[0002] In the field of metal processing, stamping forming equipment is a key device for achieving rapid shaping of sheet metal, and it is widely used in manufacturing industries such as automobiles and home appliances. However, existing sheet metal stamping forming equipment has significant functional limitations: traditional equipment has a fixed matching structure for the stamping head and die, and can only perform stamping processing for a single shape.

[0024] Example 1

The telescopic cylinder 6 drives the lifting seat 5 to move up and down. Bases 7 are fixedly mounted on the bottom surface of the lifting seat 5 and within the processing groove 3. Rollers 8 are rotatably mounted within the bases 7. The rollers 8 serve as a station switching carrier, enabling rapid switching between multiple stamping dies. Multiple mounting seats 9 are fixedly arranged in an array on the outer wall of the rollers 8. A stamping head 10 is installed on the mounting base 9 of the square roller 8, where the stamping head 10 performs the stamping action. A mold cavity 11 adapted to the stamping head 10 is installed on the mounting base 9 of the lower roller 8. The mold cavity 11 is used for stamping and forming of metal sheets. A top template 13 is movably installed in the mold cavity 11 through a spring 12. The top template 13 ejects the formed part under the action of the spring 12, realizing automatic demolding. The processing table 1 is also equipped with a drive assembly that drives the two rollers 8 to rotate synchronously and intermittently. The drive assembly ensures precise alignment of the upper and lower work positions. Through the design of multiple sets of stamping heads 10 and mold cavities 11 on the rollers 8, the stamping shape can be switched without disassembly, solving the problem of cumbersome mold replacement in traditional devices and greatly shortening the switching time.

[0026] Example 2

[0027] Please see Figure 2 and Figure 3 The drive assembly includes a fixed frame 14, a transmission sleeve 15, a transmission shaft 16, a first bevel gear set 17, and a second bevel gear set 18. The transmission sleeve 15 is rotatably mounted on the processing table 1, and one end of the transmission sleeve 15 is connected to the lower roller 8 via the first bevel gear set 17, wherein the first bevel gear set 17 transmits power to the lower roller 8.

The other end is movably inserted into the transmission sleeve 15. A limiting protrusion is fixedly provided on the rod of the transmission shaft 16, and a sliding groove is provided on the inner wall of the transmission sleeve 15 to slide and adapt to the limiting protrusion. The transmission sleeve 15 and the transmission shaft 16 achieve axial extension and synchronous rotation through the sliding cooperation of the limiting protrusion and the sliding groove, adapting to the height change of the lifting seat 5.

[0028] Example 3

[0029] Please see Figure 2 and Figure 6 The drive assembly also includes a rotating unit that drives one of the rollers 8 to rotate intermittently. The rotating unit includes a housing 19 fixedly mounted on the side of one of the bases 7, and a driving roller 21, a driven roller 22, and a brake disc 23 rotatably disposed within the housing 19.

A lever 24 is fixedly disposed at the eccentric position of the driving roller 21. A notch is provided on the side of the lever 24 near the drive wheel 23. The driven wheel 22 is coaxially and fixedly connected to the roller 8. The driven wheel 22 has grooves 25 that slide with the lever 24 at equal intervals. The lever 24 and the grooves 25 cooperate to make the roller 8 rotate intermittently. The number of grooves 25 is the same as the number of mounting bases 9. An arc-shaped groove that slides with the brake disc 23 is also provided on the driven wheel 22 between two grooves 25. The brake disc 23 and the arc-shaped groove lock the position of the roller 8 during the intermittent period to ensure stamping accuracy.

[0030] Example 4

[0031] Please see Figure 1-3 The processing table 1 is also equipped with a feeding mechanism, which includes a holding box 26, a pusher plate 27 and a pushing unit. The holding box 26 is fixedly installed on the processing table 1 and located on one side of the frame 2. The side of the holding box 26 near the frame 2 has an outlet 28 for metal plates to pass through. The holding box 26 stores the plates to be processed. The pushing unit is used to transport the metal plates in the holding box 26 to the processing slot 3 in sequence. The pushing unit realizes automatic feeding.

[0032] Example 5

[0033] Please see Figure 5 , Figure 7 and Figure 8 The feeding unit includes a lead screw 29, a nut 30, a fixed seat 31, a mounting shaft 32, and a lever 27. The top surface of the processing table 1 has symmetrical strip holes on both sides of the processing groove 3. The lead screw 29 is rotatably installed in the strip holes. The lead screw 29 is driven by a servo motor 36 set on the processing table 1. The nut 30 is installed on the lead screw 29 and is slidably set in the strip hole. The fixed seat 31 is fixedly set on the nut 30. The mounting shaft 32 is rotatably installed in the fixed seat 31. The lever 27 is fixedly installed on the mounting shaft 32. Torsion springs 33 are installed on both sides of the lever 27 on the mounting shaft 32. The other side of the holding box 26 away from the frame 2 also has a notch 34 that is clearance-fitted with the lever 27. The notch 34 allows the lever 27 to pass through.

[0034] Example 6

[0035] Please refer to the figure. Figure 8 A limiting plate 35 is also fixedly installed on the fixed base 31 on one side of the push plate 27. The limiting plate 35 restricts the rotation angle of the push plate 27 to ensure that it remains vertical when pushing the plate.

[0036] Working principle:

[0037] When switching between different molding shapes, the stepper motor 20 drives the active rotary wheel 21 to rotate. When the lever 24 is inserted into the slot 25 of the driven rotary wheel 22, it drives the driven rotary wheel 22 and the roller 8 coaxial with it to rotate by a fixed angle (corresponding to one workstation spacing). At the same time, through the transmission of the first bevel gear set 17, the transmission sleeve 15, the transmission shaft 16 (whose limiting protrusion slides in the slide groove of the transmission sleeve 15 to adapt to lifting and lowering), and the second bevel gear set 18, the other roller 8 rotates synchronously by the same angle, precisely aligning the next set of stamping heads 10 with the mold cavity 11 at the processing position. When the lever 24 disengages from the slot 25, the brake disc 23 is embedded in the arc-shaped groove of the driven rotary wheel 22 to lock the position of the roller 8. At this time, the servo motor 36 drives the lead screw 29 to rotate, causing the nut 30, the fixed seat 31, and the lever plate 27 to move towards the holding box 26. The lever 27, held vertically by the limiting plate 35, passes through the notch 34 on the side of the container 26 and enters its interior, pushing the bottom metal sheet through the discharge port 28 to the lower mold cavity 11 in the processing groove 3. The servo motor 36 reverses, and the lead screw 29 drives the nut 30 and the fixing seat 31 back. During the return process, after the lever 27 contacts the bottom metal sheet in the container 26, it overcomes the torque of the torsion spring 33 and flips towards the strip hole to avoid interference with the sheet. When the lever 27 completely exits the notch 34 of the container 26, it resets under the action of the torsion spring 33 and is held vertically by the limiting plate 35. The telescopic cylinder 6 then drives the lifting seat 5 to move down, driving the upper punch head 10 to press into the lower mold cavity 11, completing the stamping. After stamping, the telescopic cylinder 6 rises, and the top plate 13 in the mold cavity 11 ejects the formed part under the action of the spring 12. The pushing unit pushes the next sheet into the mold cavity 11, starting a new stamping cycle.

[0038] This design enables rapid switching between multiple sets of molds through roller station conversion. Combined with automatic feeding and precision indexing locking, it solves the problems of cumbersome mold replacement and long production interruption time in the background technology, and significantly improves production efficiency.

In addition, the control modules for controlling the motor and telescopic cylinder involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated. The content protected by this utility model does not involve any improvement to the internal structure and method.

[0040] The above embodiments are merely one of the preferred embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any modifications or refinements made to the main design concept and spirit of this utility model that are not of substantial significance, but solve the same technical problem as this utility model, should be included within the scope of protection of this utility model.
