1. Does a Punching Mold Have A Structure?
The punching mold is the top half of the entire pair of the punching dies which are the punching dies that mount on the press slides.
Besides, the upper component seat is the top most part of the die top and has a plate-shaped structure.
As soon as the workpiece nears the slider press, die handles will fixate it or it will directly fix to the press sliders.
The bottom half represents the lower die portion of the whole die pair.
This refers to the die that you will install on the work surface within the press.
Also, the bottom base mold resembles a plate-like component on the lower surface of the bottom mold.
Furthermore, this part is fixed directly on the work area of the plate backing of the press during operation.
The cutting edges has side walls within the punching molds contain the blade walls.
On both sides of the wall blades are edge slopes which sit on the cavity of the die.
Motive force originate from the compressed air which are in the dome air cushions.
Besides, there are parts that provide support to the punches and are known as back-side clamps.
Punch guide sleeve re tubular components offering accurate guidance for precise movement of lower and upper base dies.
The majority of them fixate on the top base die and operate with guideposts that are fixed on the lower base dies.
Guide plates are plate-shaped components containing inner holes that accurately match the punching molds.
Besides, guideposts are cylindrical components providing accurate guidance to the movement of the top and bottom base molds.
The majority of them connect to the bottom mold base and operate with guide sleeves that are connected to the top base mold.
Guide pins are pin-shaped components that protrude into material holes thus guiding their position within the die.
Also, guide plat dies are punching dies which the guide plates will guide during operation.
Using a mold means that the guide plates are not left with the convex molds.
Guide plates will guide the strip materials into the dies.
2. What Is The Operational Principle Of A Punching Mold?
The punching molds are components that perform punching process on various materials within a press.
It contains the lower and upper portion that operate together.
Convex dies are parts that make up the punching part within the die.
Concave dies are parts that make up the punching part directly on the die and are components whose inner shape is the working area.
Protective plates will prevent objects that are unwanted such as fingers from entering the parts within the die that are dangerous.
Blanking plates or rings are parts within the die that will hold the process components or stamping materials while controlling the flow of materials.
Blanks resemble rib-like components that offer control of material flow in drawing dies.
Furthermore, blanks can attach or they can be a local structure with the die or the blank ring.
Pressure sills are bars that contain a rectangular shape.
The bearing plates will form connections between the upper surfaces while supporting stamping materials.
Continuous dies are dies with double or more units and materials enter the station one at a time with strokes of the press.
This process causes the punched parts to form.
The punch side knife is a die that will cut the infeed positioning notch on the side roll.
Side pressure plates are plate-shaped pieces that put pressure on one side of the tape material.
It uses springs and pushes the other side near the material plate guide.
Ejectors are rod-shaped components that directly or indirectly eject the workpiece.
The top plates are plate-like components that shift within the die and directly or indirectly remove the workpieces or scrap materials upwardly.
Ring gears are tooth-like parts on the fine stamping die or mold plates containing teeth.
Besides, it represents a partial part of the punching mold and is not an independent component.
Limit bushings are tubing that control the minimal shut height of dies and it will fit externally to the guidepost.
Cylindrical parts called limit sleeves will control the minimal height close of dies and are located externally to the guidepost.
To ensure process components are in the correct position within the mold, you will use alignment pins.
Because of their different shapes, they are referred to as positioning pins or plates.
Punch fixing plates are components that will fix the punch.
Fixed discharge plates are also connected to the die while fixed stopper plates connect to the mold.
Unloaders are parts that eliminate off-work components from the external surface of the punching mold.
Discharge plates can both be movable or fixed and perform the function of unloading materials from the punching mold.
Furthermore, discharge screws connect to elastic discharge plates and will inhibit the static position of elastic discharge plates.
Punch single process dies are dies that will cover one process within a single stroke of the punching mold.
Two types of scrap cutters can operate with the punching mold.
One scrap cutter mounts of flange trimming dies of deep-drawing components to slide the whole circle of the trimming waste to ease removal.
The other scrap cutter sits on dies or presses to slice waste material rolls at predetermined lengths to ease removal.
Combination dies are standard and adjustable stamps that form punched parts one at a time with various shapes.
The outlines of flat punches need many sets of punches to punch them in phases.
3. What Are The Maintenance Practices Of A Punching Mold?
Make sure you have a suitable die clearance, which is the total clearance on both sides of the punching mold once it enters the bottom die.
Since there are different dies with varying clearances, make sure you use the correct one for varying plate thickness and materials.
Make sure you sharpen the punching mold frequently to increase its durability.
If you notice the mold edges wearing off and producing an arc with a radius averaging 0.1 mm, conduct sharpening.
Once you complete the sharpening process, use oilstone to eliminate burs from the cutting edge.
Thereafter, apply lubrication following demagnetization.
Frequently inspect the alignment of top and bottom seat dies within the turntables.
Poor alignment causes quick passivation of dies thus producing bad quality workpieces.
Lubricate, inspect, and conduct timely repairs on the guide keys and die holes within the turntables.
Pressure and heat will cause fine particles to stick on the surface of the punching mold following the punching process.
This results in a poor-quality punching process.
For this reason, eliminate the sticky substance using fine oil stone to perform the grinding process.
Ensure the direction of grinding matches that of the punching mold.
Avoid punching via tiny strips as it might deform the punching mold.
4. What Is The Installation Process Of A Punching Mold?
Installing a punching mold is a precise process and there are tips you should adhere to:
To make sure the punching mold operates safely and remains durable, clean the upper and lower mold bases.
- Tightening screws
Make sure you symmetrically and not sequentially tighten the fastening screws in the molds and pressure plates.
Ensure you tighten them 2 to 3 times so that each thread connection has a load.
- Height of pressure plate fixing block plate
Ensure a height that is not too low or high for the pressure plate fixing block plates.
Besides, you can fix the molds on the punch in two ways.
One way entails clamping the top mold with mold shanks and the bottle mold connects to pressure bolt plates.
The other way entails using pressure plate bolts.
- Height and diameter of die handles
Ensure the diameter and the height of the die handles do not surpass the diameter and depth of the hole of die handles of press slides.
5. What Categories Of Punching Molds Exist In The Market?
There are three categories of punching molds:
- Mechanically driven
This version makes the flywheel rotate via a primary motor, using the flywheel inertia to punch molds.
Besides, a clutch controls this version of punching mold.
It is a simple punching mold, affordable, and offers stable performance.
mechanically driven punching mold
The disadvantage is that it has to wait for the flywheel to complete turning before punching.
In addition, it contains constant punching strokes meaning it is impossible to increase its speed.
This version uses a hydraulic cylinder that drives it and you will control it with electro-hydraulic servo valves.
Furthermore, it has a high punching speed.
Also, since you can control the stroke of hydraulic cylinders, you can control the stroke of the punching head when forming molds.
Extreme environmental conditions can negatively affect this punching mold.
It requires a large area and needs yearly replacements.
- Servo motor driven
This version uses a servo motor as its driving mechanism.
It has a high punching speed while minimizing its power consumption.
This is because when there is no punching happening, motors remain static therefore consume no power.
6. What Are The Safety Precautions You Should Observe When Using A Punching Mold?
Operators need to understand how to work with the machine before handling it.
Wear protective clothing and gear during operation.
Ensure all parts are installed correctly and repair or replace faulty ones before operation.
Use special tools and not your hands when feeding and picking the parts you punch.
Keep sage distance from the punching mold and remain alert at all times.
Ensure the area around the punching mold is clean at all times and ensure the punching mold is not overloaded.
