Description

A stamping die for automobile parts

Technical Field

The invention relates to the technical field of stamping, in particular to a stamping forming die for automobile parts.

Background Art

Most of the covering parts on cars are made of steel plates, which are called automotive panels. The main processing method of automotive panels is to use stamping dies to stamp and form steel plates so as to mass produce them in the cheapest way. Stamping dies use dies installed on presses to apply pressure to materials to cause separation or plastic deformation. In industrial production, as the quality requirements for metal sheets increase, stamping dies are needed to stamp and shape metal sheets. At present, during the stamping process, the position of the mold is prone to deviation during pressing, and the vibration generated when the device is working will also cause the plate to move, resulting in errors in the stamping of the plate. In addition, the plate needs to be placed on the mold manually during the stamping process, which is inconvenient to use.

Summary of the invention

To achieve the above objectives, the present invention is implemented through the following technical solutions: A stamping die for automobile parts, specifically comprising:

A workbench, the workbench having a leg structure and a support frame arranged on the top of the workbench, the bottom of the support frame is fixedly connected to the top of the workbench, a guide device is fixedly connected to the center of the top of the workbench, telescopic push rods are fixedly connected to both sides of the inner wall of the support frame, the top of the guide device is fixedly connected to the top of the inner wall of the support frame, and a male mold and a female mold are fixedly connected to the telescopic push rods on both sides of the inner wall of the support frame;

A support platform, which has a long strip structure, and a connecting frame arranged at the bottom of the support platform, one side of the connecting frame is fixedly connected to the side of the workbench, and the top of the support platform is fixedly connected to a feeding device;

The guiding device comprises:

A guide frame, the guide frame having a square hollow structure, and guide sliders arranged at the top and bottom of the guide frame, a sliding track is arranged above and below the guide frame, the top of the guide slider extends into the inside of the sliding track and is slidably connected to the inner wall of the sliding track, the guide frame is provided with two groups and symmetrically distributed, and an extrusion spring is arranged between one side of the guide slider and the inner wall of the sliding track;

The guide plate has a rectangular structure and a threaded telescopic rod arranged on one side of the guide plate, one end of the threaded telescopic rod is fixedly connected to the guide plate, and one side of the guide plate is rotatably connected to the side of the guide frame through a rotating hinge.

A guide device is provided. When in use, the plate is sent to one side of the guide device through the feeding device. When the plate continues to move toward the guide device, it is squeezed onto the guide plate inside the guide device, slides on the surface of the guide plate, and is pushed into between the symmetrically distributed guide frames through the inclined surface of the guide plate. While the plate moves, the guide frame is pushed to both sides through the guide plate. The guide frame drives the guide slider to slide inside the sliding track and squeezes the extrusion spring. When the plate moves between the two sets of guide frames, the guide frame can be squeezed onto the plate through the reverse thrust of the extrusion spring, so that the plate to be processed can be clamped by the guide frame to avoid displacement of the plate caused by vibration generated during the stamping process, thereby avoiding vibration errors.

Preferably, the sliding rails above and below the guide frame are fixedly connected to the support frame and the workbench respectively, and the two ends of the extrusion spring are fixedly connected to the guide slider and the inner wall of the sliding rail respectively.

When the plate moves to one end of the electric conveyor belt, it continues to move toward the inside of the feeding base and enters between the two sets of oppositely arranged electric conveyor belts from one side of the electric conveyor belt. Since the electric conveyor belt drives the suction cup to rotate, the suction cup squeezes and sticks to the plate, and the plate can be driven to move inside the feeding base by the electric conveyor belt and the suction cup. When in use, you only need to insert the plate into the trapezoidal slide groove from one side of the feeding base. The feeding operation is convenient, and the set trapezoidal slide groove can guide the plate to enter the inside of the feeding base. There is no need to accurately align the feeding port when feeding, which is convenient to use.

3. This stamping mold for automobile parts is provided with guide strips and inclined chamfers. When the plate moves to a predetermined position between two sets of guide frames, the punch and the die are driven to move toward the guide frame by a telescopic push rod. When the punch and the die move to one side of the guide frame, the guide strips thereon first enter the inside of the guide frame. Since the side of the guide strip is provided with an inclined chamfer, when the position of the punch and the die is offset, the die and the punch can be pulled to the correct position through the inclined surface of the inclined chamfer, thereby avoiding stamping errors caused by the position offset of the punch and the die, and the stamping accuracy is high.
