Description

Sheet metal stamping die

technical field

The utility model relates to the field of punching dies, in particular to a punching die for sheet metal parts.

Background technique

Sheet metal stamping dies are dies used in the blanking process. According to the nature of the process, they can be divided into blanking dies, punching dies, cutting dies, notching dies, trimming dies, and cutting dies. During the blanking process, the compressor drives the punch down, which strongly collides with the blanking position of the sheet metal material plate. The gold material plate is subjected to multiple blanking operations, and the material plate may be used as the final workpiece. The unevenness of the material plate obviously affects the subsequent blanking operation and the quality of the final workpiece.

Utility model content

The purpose of this utility model is to overcome the above problems and provide a stamping die for sheet metal parts that keeps the sheet metal material plate flat and does not warp during punching, and moves the material plate for multiple stamping operations.

In order to achieve the above purpose, the technical solution adopted by the utility model is: sheet metal stamping die, including the mold base composed of upper template, lower template, guide post, guide sleeve, punch fixing plate and die fixing plate, its characteristics Yes: It also includes a punch fixed on the punch fixing plate and a first concave module and a second concave module fixed on the concave mold fixing plate, and a concave mold matched with the punch is formed between the first concave module and the second concave module Groove; there is also a pressing device on the punch fixed plate.

As a further improvement to the utility model, the pressing device is composed of a pressing spring fixed on the punch fixing plate and a pressing plate located at the end of the pressing spring. Furthermore, there are multiple pressing springs and pressing plates.

As a further improvement to the utility model, the side walls of the first concave module and the second concave module are provided with slideways respectively, and the slideways of the first concave module and the second concave module cooperate with each other to form a place for placing sheet metal material plates. .

The beneficial effects of the utility model are as follows: the pressing device presses down the rest of the material plate except the blanking position, so that the material plate remains flat and does not warp, which is beneficial to performing multiple blanking operations and improving the quality of the final workpiece; the side of the concave module The slideway of the wall defines the position of the sheet metal material sheet and forms the moving track of the material sheet.

Description of drawings

Fig. 1 is a structural diagram of the utility model;

Fig. 2 is the slideway structural diagram of the present utility model;

Among them, 1 upper template, 2 lower template, 3 guide sleeve, 4 guide post, 5 punch, 6 pressure spring, 7 pressure plate, 8 punch fixing plate, 9 concave mold fixing plate, 10 first concave module, 11 second concave module, 12 slideway, 13 sheet metal material plate, 14 groove.

Detailed ways

The figure is a preferred embodiment of the utility model, and the utility model will be further described below in conjunction with the accompanying drawings: wherein, 1 upper formwork, 2 lower formworks, 3 guide sleeves, 4 guide pillars, 5 punches, 6 pressure springs, 7 pressure Material plate, 8 punch fixed plate, 9 concave mold fixed plate, 10 first concave module, 11 second concave module, 12 slideway, 13 sheet metal material plate, 14 groove.

Referring to Fig. 1 and Fig. 2, the stamping die for sheet metal parts includes a mold base composed of an upper template 1, a lower template 2, a guide post 4, a guide sleeve 3, a punch fixing plate 8 and a die fixing plate 9, and its characteristics are: Also comprise the punch 5 that is fixed on the male mold fixed plate 8 and the first concave module 10 and the second concave module 11 that are fixed on the female mold fixed plate 9, form and convex mold between the first concave module 10 and the second concave module 11 The matching groove 14 of the mold 5; the pressing device is also provided on the punch fixing plate 8; the pressing device consists of the pressing spring 6 fixed on the punch fixing plate 8 and the pressing plate at the end of the pressing spring 7 components; the pressing spring 6 and the pressing plate 7 are multiple; when the punch 5 punches down, the pressing spring 6 and the pressing plate 7 follow the punch fixing plate 8 to go down, when the punch 5 and the sheet metal material plate When the blanking position of 13 collides, the holding plate 7 presses the remaining part of the sheet metal material plate 13 so that it does not tilt up, and the holding spring 6 is used to buffer the impact force, so as to prevent the sheet metal material plate 13 from falling on the holding plate 7. Damaged by impact. For the convenience of illustration, the slideway 12 is omitted in FIG. 1 .

A sheet metal material plate 13 is placed between the first concave module 10 and the second concave module 11, wherein the side walls of the first concave module 10 and the second concave module 11 are provided with slideways 12 respectively, and the first concave module 10 and the second concave module The slideways 12 of the modules 11 cooperate with each other for placing the sheet metal material plate 13 , and the sheet metal material plate 13 can move along the slideway 12 .       

The above-mentioned embodiments do not limit the utility model in any form, and all technical solutions obtained by means of equivalent replacement or equivalent transformation fall within the protection scope of the utility model.
