Description

Technical Field

[0001] The utility model relates to the technical field of stamping part processing, in particular to a stamping part bending die. Background Art

[0002] Stamping is a forming method that uses a press and a die to apply external force to plates, strips, pipes and profiles to cause plastic deformation or separation, thereby obtaining a workpiece (stamping) of the desired shape and size. Stamping and forging are both plastic processing (or pressure processing), collectively known as forging. The blanks for stamping are mainly hot-rolled and cold-rolled steel plates and strips, and after stamping, steel plates need to be bent using a bending die to meet actual use requirements.

[0003] The existing patent (publication number: CN217474629U) discloses a stamping part bending die, including a die table, a placement groove is opened inside the die table, a first screw is rotatably connected inside the placement groove, a fixing sleeve is threadedly connected to the surface of the first screw, the other end of the fixing sleeve is fixedly connected to a support plate, a fixing plate is welded on the top of the support plate, an electric push rod is bolted to the back of the fixing plate, a pressure plate is fixedly connected to the output end of the electric push rod, a driving structure for driving the first screw to rotate is arranged inside the placement groove, and chucks are arranged on both sides of the top of the die table; the utility model can automatically bend steel plates, and can also be conveniently bent according to the different heights of the steel plates, thereby solving the problem that the current bending die cannot automatically bend according to the height of the steel plates.

[0004] In actual use, the above patented technology fixes the steel plate at the chuck and then drives the pressure plate to bend it through an electric push rod.

In actual use, the existing technology manually judges the bending position of the steel plate, and cannot accurately judge the position of the steel plate to be bent, which may result in poor bending effect and reduced bending accuracy. Therefore, a stamping part bending die is proposed. Utility Model Content

In this embodiment, the first electric push rod 3 is turned on, and the first electric push rod 3 drives the connecting plate 4 to move so that the top plate 7 moves, so that the top plate 7 and the bending block 23 are at a suitable distance, and the distance between the top plate 7 and the bending block 23 is observed through the scale line 8, and then, the motor 10 is turned on, the motor 10 drives the first screw rod 9 to rotate, and the first screw rod 9 drives the first threaded plate 11 to move. When the first threaded plate 11 moves, the steel plate is transported. When one end of the steel plate contacts the top plate 7, the spring 5 is compressed, the pressure sensor 6 senses the value, and sends a signal to the controller. The controller receives the signal, stops the motor 10, and then bends the steel plate, thereby achieving the effect of enabling the steel plate to be bent at the required position and improving the bending accuracy.

[0024] The top outer surface of the support plate 12 is rotatably connected to the second screw rod 13, the top outer surface of the second screw rod 13 is fixedly connected to the first knob 15, and the outer surface of the second screw rod 13 is threadedly connected to the second threaded plate 14. In this embodiment, the first knob 15 is rotated, and the first knob 15 drives the second screw rod 13 to rotate, so that the second threaded plate 14 moves, and the upper and lower positions of the two clamps 20 are adjusted, and the clamps 20 are adjusted to be close to the middle of the steel plate.

[0025] The outer surface of the second threaded plate 14 is fixedly connected to two fixing plates 16, and the outer surfaces relative to each other of the two fixing plates 16 are rotatably connected to the forward and reverse screw rods 17, and the outer surfaces of the forward and reverse screw rods 17 are fixedly connected to the second knob 18, and the outer surfaces of the forward and reverse screw rods 17 are threadedly connected to two threaded blocks 19, and the two threaded blocks 19 are movably fitted with the outer surface of the second threaded plate 14, and the outer surfaces of the two threaded blocks 19 are fixedly connected to a clamping plate 20. In this embodiment, the second knob 18 is rotated, and the second knob 18 drives the forward and reverse screw rods 17 to rotate, and the rotation of the forward and reverse screw rods 17 drives the two threaded blocks 19 to move in a direction close to each other, so that the two clamping plates 20 fix the steel plate, thereby fixing one end of the steel plate.

[0026] Vertical plates 21 are fixedly connected to the top outer surface of the bending table 1 near the front and rear edges, and second electric push rods 22 are fixedly installed on the opposite outer surfaces of the two vertical plates 21.

[0028] The top outer surface of the support plate 12 is fixedly connected to two support rods, and the top outer surfaces of the two support rods are fixedly connected to a cross plate. The second screw rod 13 rotates and penetrates the outer surface of the cross rod, and the second threaded plate 14 is movably sleeved on the outer surfaces of the two support rods.

[0029] The outer surfaces of the two clamping plates 20 are fixedly connected with silicone pads. In this embodiment, the silicone pads are used to increase the friction between the clamping plates 20 and the steel plate.

[0030] Working principle: When the utility model is in use, the steel plate to be bent is fixed, and the steel plate is placed on the support plate 12. According to the height of the steel plate, the first knob 15 is turned, and the first knob 15 drives the second screw rod 13 to rotate, so that the second threaded plate 14 moves, and the upper and lower positions of the two clamping plates 20 are adjusted, and the clamping plates 20 are adjusted to be close to the middle of the steel plate.

According to the position where the steel plate needs to be bent, the first electric push rod 3 is turned on, and the first electric push rod 3 drives the connecting plate 4 to move so that the top plate 7 moves, so that the top plate 7 is at a suitable distance from the bending block 23. The distance between the top plate 7 and the bending block 23 is observed through the scale line 8, and then the motor 10 is turned on. The motor 10 drives the first screw rod 9 to rotate, and the first screw rod 9 drives the first threaded plate 11 to move. The first threaded plate 11 conveys the steel sheet when it moves. When one end of the steel sheet contacts the top plate 7, the spring 5 is compressed, the pressure sensor 6 senses the value, and sends a signal to the controller. The controller receives the signal, stops the motor 10, and makes the second electric push rod 22 work. The second electric push rod 22 on the front side drives the positioning block to move and contact the surface of the steel sheet to position the bending part of the steel sheet. The second electric push rod 22 on the rear side drives the bending block 23 to bend the steel sheet, thereby achieving the effect of enabling the steel sheet to be bent at the desired position and improving the bending accuracy.

[0031] The controller is an existing structure, and the control circuit can be implemented through simple programming by technicians in this field. It belongs to the common knowledge in this field. It is only used without modification, so the control method and circuit connection are not described in detail.
