Description

Technical Field

[0001] The utility model relates to the field of stamping dies, and more specifically to a die clamping and positioning plate for automatic loading and unloading of materials. Background Art

[0002] A stamping die is a die specially used for stamping process. The stamping process refers to applying external force to the raw material through a press and a die to cause it to undergo plastic deformation or separation, thereby obtaining the desired product.

[0003] The Chinese patent authorization announcement number: CN220560307U provides a stamping die. When using this patent, the wire or tube bent into a "Z" shape or "L" shape is placed in the forming groove, and one end of the wire or tube is inserted into the clearance hole, and the placement position of the wire or tube is fixed. The operator only needs to insert one end of the wire or tube into the clearance hole and press against the bottom of the hole each time to ensure that the position of the wire or tube placed in the die is the same each time, which solves the problem of inaccurate position of the wire or tube placed in the die in the prior art.

[0004] In the existing technology, the mold is manually loaded and unloaded by the staff in each processing operation. Most of the stamped products fit tightly with the lower mold, making it difficult for the staff to take them out. If the operation time is too long, it is easy to cause the risk of pinching the hands when the upper and lower molds are closed next time, and it also reduces the production efficiency of the equipment.

[0032] Embodiment 1:

[0033] See also Figure 1- Figure 2 A mold clamping and positioning plate for automatic loading and unloading includes a workbench 1, a top plate 2 and a conveyor belt 3. A motor 4 is fixedly connected to the inside of the workbench 1. A transmission member 5 is arranged on the top of the workbench 1. The output end of the motor 4 passes through the inner wall of the workbench 1 and is transmission-connected to the transmission member 5. Two screw rods 6 are arranged on the top of the transmission member 5. The outsides of the two screw rods 6 are both threadedly connected to cylinders 7. The telescopic end of the cylinder 7 is fixedly connected to an automatic clamping plate 8.

[0034] The specific implementation process of this embodiment is as follows: the transmission part 5 is composed of two gears and a toothed belt chain, the two gears are meshed with the toothed belt chain, the two gears are rotatably connected to the top of the workbench 1, and the two screw rods 6 are respectively fixedly connected to the top of the two gears. A screw nut is installed at one end of the cylinder 7. When the screw rod 6 rotates, the cylinder 7 can be raised and lowered on the screw rod 6. The automatic splint 8 controls the two splints to move closer or apart through the driving part, so as to clamp or release the objects. This is the prior art.

[0035] Embodiment 2:

[0036] See also Figure 1 - Figure 5 A lower mold 9 is fixedly connected to the top of the workbench 1 , an upper mold 16 is arranged at the bottom of the top plate 2 , and a conveyor belt 3 is arranged between the lower mold 9 and the transmission member 5 .

[0037] A mold bottom plate 10 is fixedly connected to the interior of the lower mold 9 , and guide grooves 91 are provided on both sides of the groove wall of the lower mold 9 .

[0038] A plurality of movable grooves 11 are formed through the top of the mold bottom plate 10 , and push blocks 12 are slidably connected inside the movable grooves 11 .

[0039] The bottom end of the push block 12 is fixedly connected with a movable column 13 , the bottom end of the movable column 13 is fixedly connected with a return spring 15 , and the bottom end of the return spring 15 is fixedly connected with the bottom end of the groove wall of the lower mold 9 .

[0040] A plurality of guide rods 14 are fixedly connected to the bottom end of the groove wall of the lower mold 9 , and the top ends of the plurality of guide rods 14 are fixedly connected to the bottom end of the mold bottom plate 10 .

[0041] The plurality of guide rods 14 are slidably connected to the plurality of movable columns 13 .

[0042] Two guide blocks 17 are fixedly connected to the bottom end of the upper mold 16 , and the two guide blocks 17 are slidably connected to the two guide grooves 91 respectively.

[0043] The specific implementation process of this embodiment is as follows: the conveyor belt 3 is used to convey the product to be processed or the processed product clamped by the automatic splint 8. The top of the upper mold 16 is externally connected to a hydraulic device, and the guide groove 91 can cooperate with the guide block 17 to facilitate the alignment of the upper mold 16 and the lower mold 9. When the upper mold 16 and the lower mold 9 are closed, the guide block 17 and the guide groove 91 are tightly combined to prevent a part of the product from being pressed into the guide groove 91 when the product to be processed is squeezed. At the same time, the size of the guide groove 91 is larger than the size of the upper splint of the automatic splint 8. When the automatic splint 8 clamps the processed product, one splint is located in the guide groove 91 and the other splint is located on the inner wall of the processed product. Then the two splints are brought together to take the finished product out of the lower mold 9.

[0044] Before mold closing, the top height of the push block 12 is slightly higher than the top height of the movable groove 11, which is used to support the product to be processed in the lower mold 9. When the mold is closed, the product is squeezed, and the top height of the push block 12 gradually becomes the same as the top height of the movable groove 11. At the same time, the reset spring 15 is squeezed to generate elastic force. When the mold is separated, the reset spring 15 releases the elastic force to make the movable column 13 and the push block 12 rise to lift the finished product, which is convenient for the automatic clamping plate 8 to clamp the finished product. The number of guide rods 14 is twice the number of movable columns 13, and every two guide rods 14 are symmetrically arranged on both sides of an movable column 13.

[0045] The working principle of the utility model is: when loading, the conveyor belt 3 sends the product to be processed to the middle of the two automatic splints 8 in sequence, and then the motor 4 controls the two screw rods 6 to rotate through the transmission member 5, so that the cylinder 7 drives the automatic splint 8 to descend, and after the automatic splint 8 descends to a suitable position, the motor 4 stops working, and the cylinder 7 pushes out the automatic splint 8 so that the automatic splint 8 is located above the product, and then the cylinder 7 maintains the position of the automatic splint 8, and the automatic splint 8 clamps the product, and then the motor 4 and the cylinder 7 continue to start, so that the automatic splint 8 places the product in the lower mold 9, and then the motor 4 and the cylinder 7 continue to control the automatic splint 8 to reset, and then The external hydraulic equipment controls the upper mold 16 to descend. During the closing process of the upper mold 16 and the lower mold 9, the guide block 17 is gradually inserted into the guide groove 91, the product is extruded and formed by the upper mold 16, and the push block 12 is squeezed into the movable groove 11 by the product. After the product is completely formed, the hydraulic equipment controls the upper mold 16 to rise, and the return spring 15 pushes the movable column 13 and the push block 12 upward, thereby separating the finished product from the lower mold 9. After that, the motor 4 and the cylinder 7 continue to control the automatic clamping plate 8 to clamp the finished product out of the lower mold 9 and place it back on the conveyor belt 3. Finally, the above process is repeated to realize a production line that can automatically load and unload materials.

[0046] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
