Description

Technical Field

[0001] This utility model belongs to the field of machining technology. Background Technology

[0002] Currently, in the automotive parts processing project development phase, there is a need for small batches of workpieces for tooling debugging and vehicle assembly testing. The production quantity of these small batches is limited, and the production cycle is not critical, but the production timeframe and quality requirements are high. However, in the current project development phase, the small batches of stamped workpieces require the fabrication of traditional, complex stamping dies suitable for mass production. The fabrication cycle for these stamping dies is long and cannot meet the timeframe requirements for providing small batches of stamped workpieces during the project development phase. Summary of the Invention

[0003] The purpose of this invention is to provide a simple stamping die for the longitudinal beam of the front subframe of an automobile. It has a short manufacturing cycle and produces high-quality stamped parts, which can meet the quality and cycle requirements for providing small batches of stamped parts during the project development stage.

[0004] The technical solution of this utility model is as follows: a rectangular base plate is used to support the entire stamping die. Four side positioning points are fixed on the upper and lower edges of the base plate for lateral positioning of the stamped workpiece. An end positioning point is fixed on the top of the base plate for end positioning of the stamped workpiece. A core is inserted into the cavity of the cylindrical workpiece. The core is inserted into the workpiece cavity to support the stamped workpiece and prevent deformation of the inner cavity of the workpiece during the stamping process. A forming block is installed on the part of the workpiece that needs to be formed for stamping and forming of the workpiece.

[0005] The beneficial effects of this utility model are: the simplified stamping die for the longitudinal beam of the front subframe of automobiles changes the traditional, more complex, and time-consuming stamping die manufacturing process. It shortens the manufacturing cycle, produces high-quality stamped parts, effectively reduces the production cycle of stamped parts, and ensures the production cycle requirements during the project development phase.

[0006] Figure 1 This is a schematic diagram of the overall structure of this utility model;

[0007] Figure 2 This is a front view of the present invention;

[0008] Figure 3 This is a top view of the present invention; Detailed Implementation

[0009] The present invention will be further described below with reference to the accompanying drawings:

[0010] like Figure 1-3As shown, 1 is the base plate, 2 is side positioning A, 3 is side positioning B, 4 is insert A, 5 is insert B, 6 is side positioning C, 7 is the forming block, 8 is side positioning D, 9 is insert C, 10 is insert D, 11 is end positioning, and 12 is the workpiece.

[0011] like Figure 1-3 As shown, side positioning A2, side positioning B3, side positioning C6, side positioning D8, and end positioning 11 are bolted to the base plate 1. The forming block 7 is placed at the position on the workpiece 12 where it needs to be stamped. The inserts A4, B5, C9, and D10 are inserted into the corresponding cavities of the workpiece 12. These components constitute the entire stamping die. All materials are Q235.

[0012] like Figure 1-3 As shown, its working principle is as follows:

[0013] The base plate 1 is used for bearing, the side positioning A2, side positioning B3, side positioning C6, and side positioning D8 are used for lateral positioning, the end positioning 11 is used for end positioning, the insert A4, insert B5, insert C9, and insert D10 are used for support, and the forming block 7 is used for forming.

[0014] like Figure 1-3 As shown, the method of using this utility model is as follows:

[0015] First, install the entire stamping die base plate 1, along with side positioning A2, side positioning B3, side positioning C6, side positioning D8, and end positioning 11, onto the designated position on the lower worktable of the stamping machine. Install the forming block 7 onto the designated position on the upper worktable of the stamping machine. Manually insert the inserts A4, B5, C9, and D10 into the corresponding cavities of the workpiece 12. Then, place the workpiece 12, along with the inserts A4, B5, C9, and D10, onto the corresponding position on the base plate 1. Start the stamping die, and the upper worktable, along with the forming block 7, descends to complete the stamping of the workpiece 12, then returns to the designated position.

[0016] After the stamping process is completed, the workpiece 12 is taken out together with the inserts A4, B5, C9 and D10. The inserts A4, B5, C9 and D10 are then manually removed from their respective cavities. The stamping of workpiece 12 is now complete.
