Small-part dense-array splicing thin plate and punching lower mold structure

Abstract

The invention discloses a small-part dense-array splicing thin plate and punching lower mold structure, which comprises a small-part dense-array splicing thin plate and a punching lower mold, wherein the small-part dense-array splicing thin plate is provided with a thin-plate small-part punching element and leftove bits and pieces, the punching lower mold is provided with a left upper reference position limiting angle block, a right upper reference position limiting angle block and a lower position limiting stop block, and the left upper reference position limiting angle block, the right upper reference position limiting angle block and the lower position limiting stop block wrap and position the peripheral edges of the small-part dense-array splicing thin plate. The small-part dense-array splicing thin plate and punching lower mold structure has the advantages that process plate edges necessary for the ordinary array splicing thin plate do not exist, the punching process of a positioning reference hole is removed, the final product of the thin-plate small-part punching element is directly formed, the punching work procedures are few, the punching cost is low, the utilization rate of a punching thin plate substrate is high, and the economic benefit is obvious.

Description

technical field [0001] The invention relates to the field of stamping forming of thin plates, in particular to a spliced ​​thin plate with a dense array of small parts and a stamping lower die structure thereof. Background technique [0002] In the stamping of thin plate small parts, the thin plate base material for the production of thin plate small part stamping parts is relatively large. Before stamping, it needs to be arranged in an array to make full use of the thin plate base material, reduce costs and avoid waste. Make CAM pattern data in it During the operation, the number of stamping parts of thin plate small parts is often tens to hundreds of pieces in one stamping. There are 4 die positioning holes designed on the edge of the plate to perform positioning. The utilization rate of the thin plate stamping array base material with plate edges and die positioning holes is relatively low. Although it has been improved, there are still more raw materials. Waste phenomen...

[0002] In the stamping of thin plate small parts, the thin plate base material for the production of thin plate small part stamping parts is relatively large. Before stamping, it needs to be arranged in an array to make full use of the thin plate base material, reduce costs and avoid waste. Make CAM pattern data in it During the operation, the number of stamping parts of thin plate small parts is often tens to hundreds of pieces. In order to improve the stamping accuracy and stamping quality, the stamping dies are designed with narrow and wide plate sides. There are 4 die positioning holes on the edge of the plate to perform positioning. The utilization rate of the thin plate stamping array base material with the edge of the plate and the positioning holes of the die is low. Although it has been improved, there are still more raw materials. Waste phenomenon, and this kind of thin plate stamping needs secondary stamping. It is necessary to stamp the process positioning round hole and process positioning waist hole on the edge of the forming plate first, and then the stamping is used to form the thin plate small parts stamping parts
