[0052] The specific structure of this application includes:

[0053] The frame 1 is welded with a plurality of steel parts and has a space inside to complete the assembly of the corresponding mechanism;

[0054] A cam mechanism 2 is installed on the frame 1. The cam mechanism 2 is an existing driving mechanism, which is connected to a driving motor or other power source to achieve power transmission;

[0055] A lifting mechanism 3 is installed at the output end of the cam mechanism 2, and the lifting mechanism 3 moves up and down under the drive of the cam mechanism 2. The lifting mechanism 3 mainly drives the subsequent upper punch assembly 4 and other components to move to achieve the upper punch function;

[0056] The upper punch assembly 4 is installed at the bottom end of the lifting mechanism 3. When the lifting mechanism 3 is lifted, the upper punch assembly 4 can move up and down accordingly.

[0057] The workbench assembly 5 is installed on the frame 1. The workbench assembly 5 is installed on the frame 1, mainly plays a supporting role, and is also used to place the subsequent shaping die, and is also used to cooperate with the subsequent stamping shaping action;

[0058] The shaping die 6 is installed on the workbench assembly 5, and the shaping die 6 corresponds to the upper punch assembly 4. The shaping die 6 in the present application is provided with a die hole, which is an outer hole of a spiral tooth shape. The die hole matches the outer wall of the workpiece to be shaped. After the workpiece is squeezed and enters the shaping die 6, the shaping can be completed;

[0059] The lower punch assembly 7 is installed on the frame 1, and the lower punch assembly 7 is located below the shaping die 6. The lower punch assembly 7 corresponds to the shaping die 6. The lower punch assembly 7 in the present application is used to push the workpiece out of the shaping die after the workpiece enters the shaping die 6, and then enters the next process through the upper push of the lower punch assembly 7;

[0060] The upper punch 403 of the upper punch assembly 4 pushes the workpiece to rotate into the shaping die 6, and the lower punch 705 of the lower punch assembly 7 pushes the workpiece to rotate out of the shaping die 6. The workpiece is a workpiece with a spiral tooth shape to be processed in this application.

[0061] In one embodiment, at least two lifting rails 8 are installed on the frame 1, and the lifting rails 8 are arranged to extend vertically in parallel at intervals, so as to provide a track for vertical movement, that is, to enable the subsequent lifting mechanism to move vertically up and down stably;

[0062] The lifting mechanism 3 comprises:

[0063] The driving connecting rod 301 is installed at the output end of the cam mechanism 2. When the cam mechanism 2 moves, the driving connecting rod 301 can move up and down accordingly, thereby driving the subsequent lifting plate to move up and down;

[0064] The lifting plate 302 is arranged between the lifting rails 8, and the top of the lifting plate 302 is hinged to the bottom of the driving connecting rod 301; the two sides of the lifting plate 302 in the present application are respectively coordinated with the lifting to ensure that the lifting plate 302 can be lifted and lowered stably, which can be achieved by the combination of grooves and protrusions or other methods.

[0065] Specifically, the upper punch assembly 4 includes:

[0066] An upper punch mounting seat 401 is mounted on the bottom of the lifting plate 302;

[0067] The upper punch thrust ball bearing 402 is mounted on the bottom of the upper punch mounting seat 401;

[0068] The upper punch 403 is connected to the upper punch thrust ball bearing 402, and the upper punch 403 is vertically arranged; the upper punch assembly 4 of the present application is lifted and lowered when the lifting plate 302 is lifted and lowered, wherein the connection method between the upper punch 403 and the upper punch thrust ball bearing 402 is the existing one, including some gaskets, seat bodies and other components, which will not be repeated here; the present application can achieve that when the upper punch 403 reaches the upper surface of the workpiece through the upper punch thrust ball bearing 402, it can drive the workpiece to rotate a certain angle and enter the shaping mold to complete the shaping process.

[0069] Because the workpiece can enter the shaping die 6 when the upper punch assembly 4 moves downward, it is necessary to ensure the stability of the structure of the shaping die 6. Therefore, the present application is designed for the workbench assembly 5, and the workbench assembly 5 includes:

[0070] A base 501 is mounted on the frame 1, and the shaping mold 6 is mounted in the middle of the base 501. The base 501 is connected to the frame 1 through some components to form a structure similar to a workbench.

[0071] A plurality of upper punch guide columns 502 are installed vertically at intervals on the base 501, and the upper punch guide columns 502 are connected with the upper punch mounting seat 401. The upper punch guide columns 502 pass through the base 501, and the top of the upper punch guide columns 502 cooperates with the upper punch mounting seat 401, so that the upper punch mounting seat 401 can move up and down along the upper punch guide columns 502;

[0072] A plurality of lower punch guide posts 503 are vertically installed at intervals on the base 501. The lower punch guide posts 503 cooperate with the subsequent lower punch assembly to enable it to move up and down stably, pushing the workpiece out of the shaping die, thereby completing the shaping process.

[0073] Specifically, Figure 2 As shown, the lower punch assembly 7 includes:

[0074] The down-punch cylinder 701 is installed at the bottom of the frame 1. The down-punch cylinder 701 is vertically arranged, and its piston rod is vertically upward;

[0075] A lower punch rod 702 is mounted on the piston rod end of the lower punch cylinder 701, and the lower punch rod 702 extends upward to resist against a subsequent lower punch mounting seat 703;

[0076] The lower punch mounting seat 703 is arranged on the lower punch guide column 503. At this time, the lower punch mounting seat 703 moves up and down along the lower punch guide column 503 under the drive of the lower punch rod 702;

[0077] The lower punch thrust ball bearing 704 is mounted on the lower punch mounting seat 703;

[0078] The lower punch 705 is vertically arranged on the lower punch thrust ball bearing 704, and the lower punch 705 corresponds to the shaping die 6. Similarly, the mounting structure of the lower punch thrust ball bearing 704 is existing and can be connected to the lower punch 705 and the lower punch mounting seat 703 through some other components. It will not be repeated here. It is only necessary that the lower punch 705 can rotate; the lower punch 705 is used to push the workpiece out of the shaping die 6.

[0079] The working process of this application is as follows:

[0080] First, push the workpiece to the shaping die 6, start the cam mechanism 2, and drive the lifting mechanism 3 to move up and down along the lifting track 8. At this time, the upper punch assembly 4 moves downward, driving the upper punch 403 to move downward, so that the upper punch 403 can reach the surface of the workpiece and continue to press down. If the spiral shape of the workpiece and the die hole shape of the shaping die are misaligned, the upper punch 403 can rotate in cooperation with the upper punch thrust ball bearing 402, thereby driving the workpiece to rotate, and then the upper punch 403 can rotate the workpiece into the shaping die 6 to complete the shaping; and at this time, the lower punch is against the workpiece, and the lower punch cooperates with the lower punch thrust ball bearing and can also rotate, and can be rotated to push out of the shaping die to complete the shaping process.
