Technical Field

[0001] The present invention relates to the field of stamping technology, and more specifically, to a lifting type CNC stamping jig. Background Art

[0002] A stamping jig is a tool used in the stamping industry. It is mainly used to assist in completing certain steps in the stamping process that cannot be formed in one go, such as cutting, partial forming or bending. A stamping jig is a tool used in the stamping process to assist the mold in completing specific stamping steps.

[0003] Among them, the invention patent CN221833151U discloses an automobile stamping die with rapid demoulding, including a mounting base, a fixed seat is fixedly connected to the middle of the top of the mounting base, the left and right sides of the inside of the fixed seat are fixedly connected to the connecting seat, the top of the connecting seat is slidably connected to a moving plate, the outer side of the moving plate is fixedly connected to a rack plate, the top of the moving plate is fixedly connected to a connecting plate, the inside of the connecting seat is rotatably connected to a transmission rod, one end of the transmission rod is fixedly connected to a worm, and the other end of the transmission rod is fixedly connected to a cylindrical gear;

[0004] When this structure is in use, the automatic film-topping function is realized by adding connecting plates, moving plates, rack plates, connecting seats, cylindrical gears and other structures to cooperate with each other. However, during the stamping process, after the mold stamps out the product, the parts that cannot be formed at one time need to be stamped again to achieve the required shape and size, which makes the structure more cumbersome when used. Summary of the invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a lifting type CNC stamping fixture, aiming to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a lifting type CNC stamping fixture comprises a support frame, on which a stamping forming component is arranged.

[0007] The stamping forming assembly includes a slide rail arranged on a support frame, a slide table is slidably connected to the slide rail, a stamping chamber is opened on the top of the slide table, an inner lining body is installed in the stamping chamber by bolts, two hydraulic rods are arranged on the top of the support frame, and the output end of each hydraulic rod extends to the top of the stamping plate and the cross plate respectively, an electric push rod is arranged on one side of the slide rail, the electric push rod is installed on the support frame by bolts, and the output end of the electric push rod extends to one side of the slide table and is detachably connected to the slide table by bolts.

[0008] It can be seen that in the above technical solution, the workpiece is placed in the inner liner body, the electric push rod is started to drive the slide to move on the slide rail to transport it to the bottom of the stamping plate, and the stamping plate is driven to move downward by the hydraulic rod on the top of the stamping plate, so that the stamping rod is driven to move downward to stamp the tool.

[0009] A stamping plate is provided at the top of the inner cavity of the support frame, and a stamping head is provided at the bottom of the stamping plate. The outer side of the stamping head is slidably connected with a first spring rod, and the first spring rod is fixed to the bottom of the stamping plate. A reinforcing cylinder is clamped at the middle of the stamping head, and a supporting ring is provided in the middle of the reinforcing cylinder. A plurality of guide rods are slidably connected to the supporting ring, and a return spring is fixedly provided at the bottom of each guide rod, and a stamping rod is fixedly provided at the bottom of the return spring, and a guide sliding ring is provided at the top of the supporting ring, and the guide rod penetrates the guide sliding ring and extends to the top of the guide sliding ring, and a ball joint is movably connected to the top of the supporting ball, and a pressing block is provided at the top of the ball joint, and an inclined groove is provided at the bottom of the pressing block, and the pressing block extends to the ball joint and is slidably connected to the ball joint, and sliders are fixedly provided on both sides of the pressing block, and the slider is slidably connected to the reinforcing cylinder, and a driving motor for driving the pressing block to rotate is provided at the top of the reinforcing cylinder.

[0010] It can be seen that in the above technical scheme, the pressure block rubs against each ball joint one by one when it rotates, and the ball joint drives the guide rod to slide on the support ring through the inclined angle of the bottom of the pressure block, and then the guide rod, the return spring and the punch rod are displaced downward by the extrusion force generated by the rotation of the pressure block to punch the workpiece. By continuously rotating the pressure block or adjusting the extension stroke of each punch rod after the pressure block rotates, it is easy to form on the workpiece at one time, so that the workpiece can reach the required shape and size. The punch head can be clamped on the top of the slide to position the workpiece, and at the same time, the first spring rod can be limited and compressed, so that the punch head is easily reset by the elasticity of the first spring rod itself when the stamping plate is reset. The ball joint is preferentially clamped on the slide to clamp the workpiece, which can effectively avoid the workpiece from being displaced and limited due to force during stamping, thereby ensuring the stamping accuracy.

[0011] A transverse plate is provided on one side of the stamping plate, and a feeding plate is provided at the bottom of the transverse plate. A second spring rod is slidably connected to the feeding plate, and the second spring rod is fixed to the bottom of the transverse plate. A plurality of clamping jaws are rotatably connected to the outer side of the feeding plate through an axle pin, and the top of each clamping jaw is movably connected to an axle pin part through an axle pin, and the tops of the plurality of axle pin parts extend to the bottom of the transverse plate, and the tops of the axle pin parts are rotatably connected to the transverse plate through an axle pin.

[0012] It can be seen that in the above technical solution, the hydraulic rod on the top of the horizontal plate drives the horizontal plate to move downward, so that the clamping jaws are forced to rotate along the axis point of the connection between the clamping jaws and the material removal plate, and then the clamping jaws are opened and clamped on the outside of the workpiece, making it easy to take out the workpiece.

[0013] Technical effects and advantages of the present invention:

[0014] The punching plate of the present invention moves downward, so that the punching head drives the punching rod to move downward to punch the tool, and the driving motor is started to drive the pressing block to rotate. When the pressing block rotates, it rubs against each ball joint one by one. The ball joint drives the guide rod to slide on the supporting ring through the inclined angle of the bottom of the pressing block, and then the guide rod, the return spring and the punching rod are moved downward by the extrusion force generated by the rotation of the pressing block to punch the workpiece;

[0015] The present invention facilitates one-time forming on a workpiece by continuously rotating the pressing block or adjusting the extended stroke of each punching rod after the pressing block rotates, so that the workpiece can reach the required shape and size.

[0016] The punch head of the present invention can be clamped on the top of the slide table to position the workpiece, and at the same time, the first spring rod can be limited and compressed, so that the punch head can be easily reset by the elasticity of the first spring rod itself when the punching plate is reset. The ball joint is preferentially clamped on the slide table to clamp the workpiece, which can effectively avoid the workpiece from being displaced and limited due to the force during punching, thereby ensuring the punching accuracy.

[0017] The invention drives the horizontal plate to move downward by a hydraulic rod on the top of the horizontal plate, so that the clamping claw is forced to rotate along the axis point of the connection between the clamping claw and the material taking plate, and then the clamping claw is opened and clamped on the outside of the workpiece, making it easy to take out the workpiece;

[0018] To summarize, through the corresponding coordination of various structures, the ball joint drives the guide rod to slide on the support ring through the inclined angle of the bottom of the pressure block, and then the guide rod, the return spring and the punching rod are moved downward by the extrusion force generated by the rotation of the pressure block to punch the workpiece. By continuously rotating the pressure block or adjusting the extension stroke of each punching rod after the pressure block rotates, it is easy to form on the workpiece in one go, so that the workpiece can reach the required shape and size. The ball joint is preferentially clamped on the slide to clamp the workpiece, which can effectively avoid the workpiece from being shifted and limited due to the force applied during stamping, thereby ensuring the stamping accuracy.
