Punches and Bushings Parts

Punches and Bushings Parts

When punching holes with a concave die, the standard of hole diameter is based on the diameter of the convex die. For example, if the hole diameter is ф10mm, the diameter of the punching die is 10mm, and the die clearance is adjusted by the size change of the punching die. 2. The selection of the punching die When punching different materials with the punching die, the different materials of the punching die will affect the selection of the die clearance. In order to ensure the quality of the hole section, dimensional accuracy, and to improve the service life of the punching die and the die, the die clearance is usually selected in consideration of the deviation in the production of the die and the wear and tear in use, and usually, only an appropriate range can be selected as a reasonable clearance.

What is The Role of A Bushing?

The use of bushings is more flexible and it can play a lot of roles. In general, bushings are a type of component that protects the equipment. The use of bushings can reduce the wear, vibration and noise of the equipment, and have the effect of corrosion prevention. The use of bushings can also facilitate the maintenance of machinery and equipment, and simplify the structure of equipment and the manufacturing process.

The role played by the custom bushingin the actual work and its application environment and purpose have a lot to do with it. In valve applications, oem bushingsare installed in the valve cover and sleeve of the valve stem to reduce valve leakage and achieve sealing. In bearing applications, bushings are used to reduce wear between the bearing and the shaft seat and to avoid increased clearance between the shaft and the bore.

Why Do Punches Break Easily?

When using stamping dies for production, the phenomenon of punch breakage will occur. The following will introduce you to the common causes of punch breakage.

Solution: Adjust the closing height so that the punch cutter is of the right length.

Solution: Adjust the positioning or feeding device.

Solution: Re-drill the big drop hole to make the drop material smooth.

Solution: Repair or re-linear cut into the block to make the punch head go up and down smoothly.

Solution: Repair the gap in the punching plate.

Solution: Change the punch again and increase the length of the cutter part.

Solution: Re-fix the punch so that it cannot move up and down.
