During processing, the spring seat workpiece 1 is fitly sleeved on the mold column 3 of the processing mold, and the mold column 3 is provided with a groove 5 corresponding to the required boss, so that the side of the spring seat workpiece 1 is squeezed into the corresponding groove 5 to form an anti-rotation boss.

[0032] Embodiment 2: In this embodiment, the number of the grooves 5 is greater than or equal to two.

[0033] The rest is the same as in Example 1.

[0038] When in use, according to the number of anti-rotation bosses required, after processing one anti-rotation boss, the processing mold is rotated to drive the mold table 2, the mold column 3 and the spring seat workpiece 1 to rotate as a whole to the next position to be processed, and then the extrusion process is performed through the extrusion device 9. The rotation of the processing mold is driven by the stepper motor 13, and the rotation angle is determined according to the anti-rotation bosses required to be processed. For example, if the number of anti-rotation bosses to be processed is two, after processing the first one, the processing mold is driven by the stepper motor 13 to rotate 180 degrees, and then the next anti-rotation boss is processed; if the number of anti-rotation bosses to be processed is three, after processing the first one, the processing mold is driven by the stepper motor 13 to rotate 120 degrees, and then the next anti-rotation boss is processed.

The movable mold base 91 is inverted U-shaped, and its two lower ends are slidably connected to the extrusion platform 6. After the processing mold is arranged on the mold base 8, the height of the horizontal part of the movable mold base 91 is higher than the height of the mold platform 2, and the length is longer than the length of the corresponding side of the mold base 8; the extrusion member 92 is detachably arranged on the horizontal part of the movable mold base 91 and is arranged close to the processing mold. The extrusion member 92 is arranged corresponding to the groove 5 on the mold column.

[0043] The rest is the same as in Example 3.

[0044] When the extrusion device of this embodiment is used, the movable die seat 91 is pushed by the hydraulic device 10, moves on the extrusion platform 6 in the direction of the processing die, and contacts and extrude the spring seat workpiece 1 through the extrusion member 92. The setting of the height and length of the movable die seat 91 can ensure that the movement of the movable die seat 91 will not be hindered by the die seat 8 and the die table 2 during the extrusion process.

[0048] Embodiment 7, the extrusion piece 92 of this embodiment includes an extrusion portion 921 and a connection portion 922, the connection portion 922 is T-shaped, a connection groove 923 is provided on the horizontal part of the movable mold base 91 corresponding to the connection portion 922, and the connection portion 922 is limited in the connection groove 923; the extrusion portion 921 is provided outside the end of the connection portion 922 close to the processing mold, the extrusion portion 921 and the connection portion 922 are integrally formed, the shape of the extrusion portion 921 is adapted to the shape of the groove 5, and two threaded holes 924 are provided in the bottom of the connection groove 923, such as Figure 7-9 As shown, the connecting portion 922 is also provided with two threaded holes 924 corresponding to the threaded holes 924 in the connecting groove 923 , and the connecting portion 922 is bolted in the connecting groove 923 .

[0049] The rest is the same as Example 5.

[0050] The extrusion piece 92 in this embodiment is detachably fixed on the movable mold base 91, and the extrusion piece 92 can be replaced as needed. The extrusion piece 92 with different shapes of the extrusion part 921 or the extrusion piece 92 with different sizes of the extrusion part 921 can be replaced to adapt to the need to process anti-rotation bosses of different shapes and sizes. The T-shaped structure of the connecting part 922 can also limit the extrusion piece 92, and the screw fixation can ensure the stability of the connection of the extrusion piece 92.

[0051] Embodiment 8: The hydraulic device 10 of this embodiment is a hydraulic cylinder. A hydraulic seat 17 is provided below the hydraulic cylinder. The hydraulic seat 17 is fixed to the upper surface of the extrusion platform 6. The telescopic end of the hydraulic cylinder is fixed to the horizontal part of the movable mold seat 91.

[0052] The rest is the same as Example 5.

[0053] When the hydraulic cylinder in this embodiment is actually used, that is, when it extends in the direction of the processing mold to drive the extrusion part 92 to process the spring seat workpiece 1, after the extrusion degree is reached, that is, after the spring seat workpiece 1 is extruded to form an anti-rotation boss, the hydraulic cylinder needs to maintain the current extension state for pressure maintenance to prevent the spring seat workpiece 1 from rebounding, and the pressure maintenance time is 30-60s.

[0054] Embodiment 9. This embodiment also includes two guide rods 18.

[0055] The rest is the same as Example 8.

[0056] In Example 10, the function of the guide rod 18 and the guide sleeve 19 is to guide the extrusion device 9 when the extrusion device 9 moves for extrusion, that is, it can further ensure that the extrusion device 9 moves along a straight line close to the spring seat workpiece 1 for processing, thereby ensuring the processing accuracy.

[0058] The rest is the same as in Example 3.

[0059] The model of the inductive counter 20 in this embodiment is SD76, which is an infrared automatic inductive electronic digital display counter. When not processed, the inductive counter cannot detect the object and does not count. In specific use, when the extrusion device 9 approaches the spring seat workpiece 1 for extrusion, the inductive counter 20 detects the part of the extrusion device 9 that is close to and in contact with the spring seat workpiece 1, and counts once each time it is detected. Since each spring seat workpiece 1 may need to be extruded multiple times (multiple anti-rotation bosses need to be processed), within a period of time, the number of counts of the inductive counter 20 is divided by the number of anti-rotation bosses that need to be processed for the spring seat workpiece 1 processed during this period of time, and the number of spring seat workpieces 1 that have been processed during this period of time can be obtained. That is, within the time range y, after the last spring seat workpiece 1 is processed, the count of the inductive counter 20 is m, and within this period of time, the number of anti-rotation bosses processed for each spring seat workpiece 1 is n, then the number of spring seat workpieces 1 processed during this period of time b = m / n.

[0060] The embodiments described above are merely descriptions of preferred implementation modes of the present invention, and are not intended to limit the concept and scope of the present invention. Without departing from the design concept of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary engineering technicians in the field should fall within the protection scope of the present invention.
