Description

Technical Field

[0001] The utility model relates to the technical field of clamps, in particular to a clamp for processing metal stamping parts. Background Art

[0002] Stamping is a forming processing method that uses a press and a die to apply external force to plates, strips, tubes and profiles to cause them to undergo plastic deformation or separation, thereby obtaining workpieces of the desired shape and size. When stamping parts are produced, metal sheets are often used for stamping for production and manufacturing.

[0003] The existing clamps for processing stamping parts are large in size and heavy in weight. After clamping the metal sheets, it is not convenient to stably move and transport them during the stamping process, which in turn affects the convenience of stamping the metal sheets. For this reason, we propose a clamp for processing metal stamping parts. Utility Model Content

[0004] The utility model mainly provides a clamp for processing metal stamping parts, which solves the problem in the prior art that due to the large size and heavy weight of metal plates, it is not convenient to stably move and transport the metal plates during the stamping process after clamping, thereby affecting the convenience of metal plate stamping.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A fixture for processing metal stamping parts includes a mounting frame, a fixed die arranged on the mounting frame, and a die arranged on the mounting frame corresponding to the position above the fixed die; the mounting frame is provided with two mounting slots, one of which is provided with a displacement guide rod, and the other is rotatably connected with a displacement screw rod, and the mounting frame is provided with a power mechanism for driving the displacement screw rod to rotate; it also includes a clamping frame, one side of which is threadedly connected to the displacement screw rod, and the other side is slidably connected to the displacement guide rod; a plurality of rotating wheels are rotatably connected in a straight line on the mounting frame corresponding to the mounting slots, and the clamping frame is provided with a support slot for matching the rotating wheels; a first lifting mechanism is provided on both sides of the clamping frame, and a clamping assembly is provided on each of the first lifting mechanisms. Among them, the fixed die and the die rod can adopt existing technologies as long as they can realize the stamping processing of metal sheets. When in use, the metal sheet to be processed is moved to the fixed die and located between the two clamping assemblies, and then the two sides of the metal sheet are clamped by the clamping assemblies on both sides. If the metal sheet needs to be displaced during the processing, the clamping assembly and the clamped metal sheet are first driven to rise by the first lifting mechanism, and then the displacement screw is driven to rotate by the power mechanism, so as to cooperate with the displacement guide rod to drive the clamping frame to move forward and backward. After the displacement, the clamping assembly and the clamped metal sheet are driven to descend by the first lifting mechanism, so as to continue to stamp the metal sheet; at the same time, during the stamping processing or displacement of the clamping frame, the multiple rotating wheels provided can support the clamping frame. The structure of the present application can clamp the metal sheet during the stamping processing, and can drive the metal sheet to move; at the same time, the first lifting mechanism is provided, which can drive the metal sheet to rise and move during the clamping process, so as to avoid the wear of the metal sheet and the fixed die, and avoid the stamping forming part being stuck in the fixed die and causing inconvenience in displacement; and the rotating wheels provided can provide good support for the clamping frame, and the displacement screw can drive the clamping frame to move accurately.

[0007] Furthermore, the front and rear ends of the clamping frame are provided with a sink groove, and the two sink grooves are provided with a displacement mechanism, and the displacement mechanism is provided with a second lifting mechanism, and the second lifting mechanism is displaced forward and backward by the displacement mechanism, and the second lifting mechanism is provided with a conveying roller mechanism, and the conveying roller mechanism is displaced up and down by the second lifting mechanism. Among them, the conveying roller mechanism adopts any one of the prior art, as long as it can drive the metal sheet to be displaced. When in use, the distance between the two second lifting mechanisms can be adjusted by the displacement mechanism provided at both ends, so as to transport metal sheets of different lengths, and the second lifting mechanism can drive the conveying roller mechanism to move up and down, so as to avoid the corresponding structure affecting the processing of the metal sheet when stamping and displacing the metal sheet. The distance between the two conveying roller mechanisms is not enough to prevent the metal sheet from falling. When the metal sheet moves to one conveying roller mechanism, it will be supported by the conveying roller mechanism, and the other conveying roller mechanism will cooperate with the displacement. After the second lifting mechanism descends, the metal sheet on the conveying roller mechanism can fall onto the fixed mold, so that it is supported by the fixed mold and clamped by the two clamping components.

[0008] Furthermore, the first lifting mechanism includes a first screw rod rotatably connected to the mounting frame, a first guide rod disposed on the mounting frame, and a first lifting block threadedly connected to the first screw rod, the first lifting block is slidably connected to the first guide rod, and the clamping assembly is disposed on the first lifting block; a first motor is disposed at the bottom side of the clamping frame to drive the first screw rod to rotate. With this structure, the first screw rod can be driven to rotate by the first motor, thereby cooperating with the first guide rod to drive the first lifting block to move up and down, thereby conveniently driving the clamping assembly installed on the first lifting block to move up and down.

[0009] Furthermore, the clamping assembly includes a clamping cylinder disposed inside the first lifting block, and movable clamping plates are disposed at the output ends of the clamping cylinders on both sides. With this structure, the metal sheet can be clamped conveniently, and in conjunction with the first lifting blocks disposed on both sides, the two clamping cylinders simultaneously drive the two movable clamping plates to move closer or farther away, thereby keeping the metal sheet in the middle position.

[0010] Furthermore, the second lifting mechanism adopts a lifting cylinder. The conveying roller mechanism is arranged at the output end of the lifting cylinder. The lifting cylinder is adopted, which has a simple structure and is easy to use.

[0011] Furthermore, the displacement mechanism includes a first fixed frame installed in the sink, a matching screw is threadedly connected to the first fixed frame, the inner end of the matching screw is rotatably connected to the second fixed frame, a matching guide rod is provided on the second fixed frame, the matching guide rod is slidably connected to the first fixed frame, the outer end of the matching guide rod is provided on the third fixed frame, the third fixed frame is provided with a second motor, the output end of the second motor is fixedly connected to the outer end of the matching screw; the lifting cylinder is provided on the second fixed frame. With this structure, the matching screw can be driven to rotate by the second motor, so that the matching screw is displaced on the first fixed frame, so that the second fixed frame and the third fixed frame follow the displacement, and the provision of the matching guide rod can limit the second fixed frame and the third fixed frame to prevent them from rotating, so that the second motor can drive the matching screw to rotate.

[0012] Beneficial effects: The structure of the present application can clamp the metal sheet during the stamping process and can drive the metal sheet to move; at the same time, a first lifting mechanism is provided, which can drive the metal sheet to rise and move during the process of being clamped, thereby avoiding wear between the metal sheet and the fixed die, and avoiding the stamping-formed part from being stuck in the fixed die, causing inconvenience in displacement; and the rotating wheel provided can provide good support for the clamping frame, and the displacement screw provided can drive the clamping frame to move accurately.
