Description

Technical Field

[0001] This utility model belongs to the field of stamping die technology, and specifically relates to a forming structure of a stamping die. Background Technology

[0002] The metal part on the stamping die in punching machine tools, also called punch bar, punch needle or punch, is installed on the stamping die to perform continuous punching, stamping and cutting operations, so as to separate or plastically deform the processed material, thereby obtaining the desired finished or semi-finished product.

[0003] In traditional stamping dies, the punch and the slot have the same shape. During long-term operation, the friction between the punch and the hole will generate fine powder, causing blockage. The punch will not run smoothly in the hole, and is prone to breakage. It will also generate a lot of heat, affecting the service life of the punch. Utility Model Content

[0004] This invention provides a forming structure for a stamping die to solve the above-mentioned technical problems.

[0005] The solution adopted by this utility model to achieve its technical effect is as follows:

[0006] A forming structure for a stamping die includes a lower die and an upper die; the top of the lower die is provided with a forming groove and a lubrication groove; the lubrication groove is located above the forming groove; a lubrication groove is vertically provided on the side wall of the lubrication groove; a punch is provided at the bottom of the upper die; a lubrication protrusion is vertically provided on the outer side of the punch; the punch can be vertically slidably inserted into the lubrication groove; the lubrication protrusion can be vertically slidably inserted into the lubrication groove; and a chip removal hole is provided on the side wall of the lubrication groove.

[0007] Preferably, the cross-section of the lubrication groove and the lubrication protrusion is semi-circular.

[0008] Preferably, a plurality of lubrication grooves and lubrication protrusions are provided correspondingly, and the plurality of lubrication grooves are evenly spaced on the inner sidewall of the lubrication groove, and the lubrication protrusions are evenly spaced on the outer sidewall of the punch.

[0009] The beneficial effects of this invention are as follows: the forming part of the product remains unchanged, namely the forming groove; the cavity for the stroke distance that the punch needs to press down into the groove is transformed into a lubrication groove; a lubrication groove is provided on the side wall of the lubrication groove; and a lubrication protrusion is provided on the outer side wall of the punch. The sliding fit between the lubrication protrusion and the lubrication groove allows for smoother punching operation. Simultaneously, a chip removal hole is provided on the side wall of the lubrication groove, through which the powder and heat generated during punching are discharged. This invention ensures smooth operation and effectively extends the service life of the punch. Attached Figure Description
