Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, in particular to a stamping shaping die positioning structure. Background Art

[0002] With the rapid development of the automobile industry, the requirements for the versatility and stability of automobile parts are getting higher and higher, and the cycle is getting shorter and shorter, and the cost control is getting higher and higher. Therefore, the positioning of the stamping die selected in the stamping die development process is required to have excellent performance such as quick change, stability and economy. The existing stamping die fixed positioning pin structure is difficult to meet this requirement. The existing stamping die positioning structure basically fixes the positioning pin directly on the die, such as Figure 1 As shown. The die must be removed before assembly. If adjustment is required, the bottom hole can only be enlarged on the basis of the original die positioning pin hole, the original positioning pin must be enlarged again, and a step structure must be changed. Disassembly, assembly and adjustment are inconvenient and the efficiency is relatively low. Utility Model Content

[0003] The utility model aims to remedy the defects of the prior art and provide a stamping die positioning structure.

[0004] The utility model is realized by the following technical solutions:

[0005] A stamping forming die positioning structure comprises a lower template, a die fixing plate is fixed on the lower template, a die is fixed on the die fixing plate, a positioning pin seat fixing groove is opened on the die, a positioning pin fixing seat is installed in the positioning pin seat fixing groove, and a positioning pin is fixed on the positioning pin fixing seat.

[0006] A bolt countersunk hole is opened on the positioning pin fixing seat, and a threaded hole corresponding to the bolt countersunk hole is opened on the die. The threaded hole is located below the positioning pin fixing groove. The bolt countersunk hole is a stepped hole. The positioning pin fixing seat is fixedly connected to the die through bolts.

[0007] A locating pin mounting hole is opened on the locating pin fixing seat, and a countersunk hole is provided on the reverse side of the locating pin mounting hole. The locating pin is a stepped locating pin, and the locating pin passes through the locating pin mounting hole from the lower end thereof, and the upper end of the locating pin passes through the locating pin mounting hole, and the lower end hanging platform of the locating pin is located in the countersunk hole on the reverse side of the locating pin mounting hole.

[0008] There are two positioning pin seat fixing grooves, and the two positioning pin seat fixing grooves are located at two ends of the middle part of the die.

[0009] The advantages of the utility model are: the utility model sets a locating pin fixing seat, passes the stepped locating pin through the locating pin fixing seat, hangs it with a step, the locating pin fixing seat is fixedly connected to the die by bolts, and the locating pin fixing seat is fixed in the locating pin seat fixing groove. When the locating pin needs to be adjusted, it can be achieved by directly adjusting or replacing the locating pin fixing seat, which well solves the problems of the existing technology that the positioning is difficult to replace, the replacement cycle is long, the cost is high, the operation is complicated, etc. The utility model does not need to repeatedly process the fixing groove or repeatedly disassemble and assemble the die during adjustment, which reduces the secondary processing cost caused by the debugging process and saves the adjustment cycle.

[0018] like Figure 3 , 4 As shown in Figures 5 and 6, a positioning structure of a stamping die includes a lower die plate 1, a die fixing plate 2 is fixed on the lower die plate 1, a die 3 is fixed on the die fixing plate 2, a positioning pin seat fixing groove 4 is provided on the die 3, a positioning pin fixing seat 5 is installed in the positioning pin seat fixing groove 4, and a positioning pin 6 is fixed on the positioning pin fixing seat 5. In this embodiment, two positioning pin seat fixing grooves are provided, and the two positioning pin seat fixing grooves are located at both ends of the middle part of the die.

[0019] like Figure 7 , 8As shown, a bolt countersunk hole 9 is opened on the positioning pin fixing seat 5, and a threaded hole 10 corresponding to the bolt hole 9 is opened on the die 3. The threaded hole 10 is located below the positioning pin seat fixing groove 4. The bolt countersunk hole 9 is a stepped hole. The positioning pin fixing seat 5 is fixedly connected to the die 3 by a bolt 11.

[0020] A locating pin mounting hole is opened on the locating pin fixing seat 5, and a countersunk hole is provided on the reverse side of the locating pin mounting hole. The locating pin is a stepped locating pin, and the locating pin passes through the locating pin mounting hole from the lower end thereof, and the upper end of the locating pin passes through the locating pin mounting hole, and the lower end hanging platform of the locating pin is located in the countersunk hole on the reverse side of the locating pin mounting hole.

[0021] During assembly, first fix the die 3 on the die fixing plate 2, pass the stepped locating pin 6 through the locating pin mounting hole on the locating pin fixing seat 5, and hang it through the step, then place the locating pin fixing seat 5 in the locating pin seat fixing groove 4 on the die 3, and fix the locating pin fixing seat 5 in the locating pin seat fixing groove 4 by bolts to complete the assembly.

[0022] The die 3 is assembled and fixed on the die fixing plate 2 by bolts and pins, and the die fixing plate 2 is fixed on the lower mold plate 1 by bolts and pins, thus completing all the assemblies.

[0023] There are two reference holes 8 on the product to be stamped and shaped in this embodiment, so two positioning pin seat fixing grooves 4 are opened on the die 3, and a positioning pin fixing seat 5 is installed in each positioning pin seat fixing groove 4, and a positioning pin 6 is installed on each positioning pin fixing seat 5. When the utility model is in use, the two positioning pins 6 are aligned with the two reference holes 8 on the product 7 to be stamped and shaped, and the product 7 to be stamped and shaped is positioned by the positioning pins 6.
