Description

Technical Field

[0001] This utility model relates to the technical field of stamping machines, specifically a stamping machine for stamping metal products. Background Technology

[0002] With the progress and development of society, metal products are increasingly widely used in various fields of industry, agriculture and life. When processing existing metal products, stamping machines are used. Stamping is a forming process that uses a press and a die to apply external force to sheet metal, strip, tube and profile, causing plastic deformation or separation, thereby obtaining workpieces (stamped parts) of the required shape and size.

[0003] A search revealed a utility model patent in China with patent publication number CN217315560U: a stamping equipment for processing metal products, including a base, a fixed plate fixedly connected to the top of the base, a stamping machine body and a worktable fixedly connected to the top of the fixed plate, a clamping mechanism inside the fixed plate, the clamping mechanism including a motor fixedly connected to the right side of the fixed plate, a first threaded rod fixedly connected to the output shaft of the motor, a moving block threadedly connected to the outer surface of the first threaded rod, the clamping mechanism also including a fixed rod fixedly connected between the left and right sides of the inner cavity of the fixed plate and a square hole opened on the right side of the upper surface of the fixed plate, and a through hole opened inside the moving block;

[0004] However, existing technologies require manual placement of the objects to be stamped and removal of the stamped objects, posing certain safety hazards and easily causing accidents, thus resulting in low safety. Furthermore, during the stamping operation, both the stamping module and the metal parts are subjected to significant impact forces, which also exert considerable impact on the support platform, severely affecting the service life of the stamping machine and hindering the processing of metal products. Therefore, a stamping machine specifically designed for stamping metal products is needed to address these issues. Utility Model Content

[0010] The placement plate is equipped with a limit mechanism for limiting the movement of materials.

[0011] Preferably, the limiting mechanism includes two clamping plates, two fixing plates are symmetrically fixedly installed on the placement plate, and two second springs are symmetrically fixedly installed on each of the two fixing plates. The two second springs on the same side are fixedly connected to the corresponding clamping plates.

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, the present invention provides a stamping machine for stamping metal products, which has the following beneficial effects:

[0019] The workpiece to be stamped is placed on the placement plate, and the limiting mechanism limits its movement. The motor is started, and the motor drives the screw to rotate, thus moving the placement plate along with the workpiece on the worktable. When the placement plate abuts the stop plate, it stops moving and is now in the middle of the worktable. Two electric cylinders are then activated, which drive the connecting plate and the stamping plate to move. The stamping operation is performed through the stamping plate. During stamping, the pressure generated by the stamping plate on the buffer plate compresses multiple dampers and the first shock-absorbing spring, causing the two support plates to move relative to each other. This reduces the impact force on the buffer plate, protects the buffer plate and the worktable, and extends the service life of the buffer plate. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example

[0027] Please see Figure 1 and Figure 2A stamping machine for stamping metal products includes a worktable 1, a mounting frame 2 fixedly installed on the worktable 1, two electric cylinders 3 symmetrically fixedly installed on the mounting frame 2, the two electric cylinders 3 being connected by a connecting plate 4, and a stamping plate 5 being provided on the connecting plate 4.

[0028] Please see Figure 1-4 A buffer mechanism is provided on the workbench 1, including a buffer plate 6. A placement plate 7 is slidably mounted on the buffer plate 6. The workpiece to be stamped is placed on the placement plate 7. A stop plate 8 is fixedly mounted on the buffer plate 6. A motor 9 is fixedly mounted on the buffer plate 6. A screw 10 is fixedly mounted on the output end of the motor 9. A threaded hole is opened on the placement plate 7, and the screw 10 is threadedly connected to the threaded hole. When the motor 9 is started, the motor 9 provides power to drive the screw 10 to rotate, thereby moving the placement plate 7 along with the workpiece on the workbench 1. When the placement plate 7 abuts against the stop plate 8, it stops moving and is now in the middle of the workbench 1. Two electric cylinders 3 are started, which drive the connecting plate 4 and the stamping plate 5 to move. The stamping operation is performed through the stamping plate 5. Multiple rollers 11 are rotatably mounted on the bottom end of the placement plate 7. Two sliding rollers 11 are symmetrically opened on the buffer plate 6. The guide rail 12 has corresponding rollers 11 that are slidably connected to the guide rail 12. Multiple dampers 13 are symmetrically fixedly installed on the buffer plate 6. The other end of each damper 13 is fixedly connected to the worktable 1. Each damper 13 is fitted with a first damping spring 14. The two ends of each first damping spring 14 are fixedly connected to the worktable 1 and the buffer plate 6, respectively. Two support plates 15 are symmetrically hinged to the bottom end of the buffer plate 6. An auxiliary roller 16 is rotatably installed on each support plate 15. Tension springs are provided on both support plates 15. During stamping, the pressure generated by the stamping plate 5 on the buffer plate 6 causes the multiple dampers 13 and the first damping springs 14 to compress, causing the two support plates 15 to move relative to each other, thereby reducing the impact force on the buffer plate 6, protecting the buffer plate 6 and the worktable 1, and extending the service life of the buffer plate 6.

[0029] Please see Figure 1-4 The placement plate 7 is equipped with a limiting mechanism for limiting the material. The limiting mechanism includes two clamping plates 18 and two fixed plates 17 are symmetrically fixedly installed on the placement plate 7. Two second springs 19 are symmetrically fixedly installed on each of the two fixed plates 17. The two second springs 19 on the same side are fixedly connected to the corresponding clamping plate 18. Limiting rods are fixedly installed on each of the two clamping plates 18. The two limiting rods are slidably connected to the two fixed plates 17 respectively. The object is clamped and limited by the cooperation of the two clamping plates 18 and the multiple second springs 19, making the object more stable and less prone to displacement during processing.

[0030] Please see Figure 2 and Figure 3A second damper 20 is fixedly installed on the workbench 1. The other end of the second damper 20 is fixedly connected to the buffer plate 6. A third damping spring 21 is fitted on the second damper 20. The two ends of the third damping spring 21 are fixedly connected to the workbench 1 and the buffer plate 6 respectively. The buffer plate 6 is made more stable by the setting of the second damper 20 and the third damping spring 21.

[0031] Please see Figure 1-3 It should also be noted that two stabilizing rods 22 are symmetrically fixedly installed on the mounting bracket 2, and the placement plate 7 is slidably connected to the two stabilizing rods 22. The setting of the two stabilizing rods 22 makes the placement plate 7 more stable when it moves.

[0032] Please see Figure 3 The placement plate 7 is provided with positioning points 23, which makes it easy to find the center placement point of the placement plate 7.

[0033] Please see Figure 1-3 A U-shaped plate 24 is fixedly installed on the buffer plate 6, and the screw 10 is rotatably connected to the U-shaped plate 24. The U-shaped plate 24 makes the screw 10 more stable when rotating.

[0034] Please see Figure 4 Both clamping plates 18 are equipped with rubber pads 25, which makes the clamping of the object by the two clamping plates 18 more stable.

[0035] In summary, when using this stamping machine for stamping metal products, the workpiece to be stamped is placed on the placement plate 7. The workpiece presses against the two clamping plates 18, causing the multiple second springs 19 to compress. The elastic force of the second springs 19 then reacts against the two clamping plates 18, thus clamping and limiting the workpiece. The motor 9 is then started. This motor is a commercially available device known to those skilled in the art; we are only using it practically without making any structural or functional improvements, which will not be elaborated upon here. The motor is equipped with a matching control switch, the installation position of which is selected according to actual practical needs for easy operation. The motor 9 provides power to drive the screw. 10. Rotation operation is performed, so that the placement plate 7 carries the parts and moves on the worktable 1. When the placement plate 7 abuts against the abutment plate 8, the movement stops. At this time, it is in the middle of the worktable 1. The two electric cylinders 3 are activated, and the two electric cylinders 3 drive the connecting plate 4 and the stamping plate 5 to move. The stamping plate 5 performs the stamping operation. During the stamping, the pressure generated by the stamping plate 5 on the buffer plate 6 causes multiple dampers 13 and the first shock-absorbing spring 14 to compress, and causes the two support plates 15 to move relative to each other, thereby reducing the impact force on the buffer plate 6, protecting the buffer plate 6 and the worktable 1, and extending the service life of the buffer plate 6. The damper 20 and the third shock-absorbing spring 21 are set to assist in the shock absorption and buffering of the buffer plate 6.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
