Problems solved by technology

[0002] The rolling and bending operation of the existing plate needs to be completed with the cooperation of multiple stations. After the bending operation is performed on the bending part, it is transferred to another station for the secondary bending operation of positioning its tail end. The whole plate forms a semi-enclosed Ring structure; due to the replacement of the station, the positioning accuracy is affected, and the secondary processing operation is time-consuming and laborious

Embodiment 1

[0030] refer to Figure 1-2 As shown, this embodiment is a seesaw-type stamping die structure, which includes support plates 1 arranged at relative intervals on the lower template, forming blocks 2 that are rotatably connected to the top ends of the support plates 1 , and set between the opposite support plates 1. The elastic plate 3 for elastically supporting the bottom of the forming block 2, the symmetrical support frame 5 for supporting the product 4 to be stamped on both sides of the supporting plate 3, and the punch above the centerline of the two opposite forming blocks 2 6. The inner side of the forming block 2 is provided with an arc-shaped groove 21, the punch punches the bottom of the arc-shaped groove 21, and the top of the arc-shaped groove 21 rotates to the center line.

[0031] The top end of the support plate 1 close to its inner side is connected with the forming block 2 through the rotating shaft 11 .

[0032] The bottom of the support plate 1 is embedded in...

Embodiment 2

[0040] refer to Figure 1-2 As shown, this embodiment is a method for verifying stamping accuracy of a seesaw stamping die:

[0041] In the existing stamped parts, its structure mainly includes one of the features connected with the connecting parts that have a matching relationship with the stamped part, that is, the associated feature, which is an important part of the stamped part. These features The accuracy requirements are relatively high and controlled within the range of ±0.5mm; the second is other features that do not participate in coordination and positioning during the manufacturing process, as well as other features such as transition structures, reinforcement structures, or connection structures that connect various associated features, that is, Secondary features, which mainly play the role of positioning, transition, reinforcement or connection in the structure, have relatively low accuracy requirements, and contribute little to the accuracy of individual compo...

Abstract

The invention discloses a warped type stamping die structure and a stamping precision verification method thereof. The structure comprises supporting plates oppositely arranged on a lower die plate atintervals, forming blocks rotationally connected with the top ends of the supporting plates, elastic plates arranged between the opposite supporting plates and used for elastically supporting the bottom of the forming blocks, symmetrical supporting frames arranged on the two sides of the supporting plates and used for supporting a product to be stamped, and a punch arranged above the center linesof the two opposite forming blocks; and an arc-shaped forming groove is formed in the inner side of each forming block, the punch punches the bottom ends of the arc-shaped forming grooves, and the top ends of the arc-shaped forming grooves rotate towards the center lines. According to the structure, one-time punching and bending operation of the product is realized, and the product precision is ensured.

Description

technical field [0001] The invention belongs to the technical field of stamping dies, and in particular relates to a seesaw type stamping die structure and a stamping accuracy verification method thereof. Background technique [0002] The rolling and bending operation of the existing plate needs to be completed with the cooperation of multiple stations. After the bending operation is carried out on the bending part, it is transferred to another station for the secondary bending operation of positioning its tail end. The whole plate forms a semi-enclosed Ring structure; due to the replacement of the station, the positioning accuracy is affected, and the secondary processing operation is time-consuming and laborious. Contents of the invention [0003] The purpose of the present invention is to solve the above-mentioned technical problems, and provide a seesaw stamping die structure and a stamping precision verification method, so as to realize the one-time stamping and bendi...
