[0002] With the rapid development of the automobile industry, the demand for auto parts is increasing, and the requirements for the quality, precision and production efficiency of parts are becoming higher and higher. In the production process of auto parts, stamping technology is one of the key manufacturing links, and stamping dies are important tools to realize the stamping process.

[0003] The Chinese utility model patent currently announced as CN207655743U discloses a stamping die for automobile parts, which is provided with a base, a lower die and an upper die. The top of the base is provided with a lower die, and pillars are installed at the four corners of the bottom of the lower die. The bottom of the pillars is plugged into the top of the base. An impact groove is opened in the middle of the top of the upper die, and columns are installed on both sides of the top of the base. A top plate is installed on the top of the two groups of columns, and hydraulic cylinders are installed on both side walls of the bottom of the top plate. The bottom of the hydraulic cylinder is plugged with a piston rod, and the bottoms of the two groups of piston rods are installed on the top of the upper die. An impact block is installed at the bottom of the upper die. The utility model is connected to a pillar through the bottom of the lower die, and the pillar is plugged into the placement groove. The spring in the placement groove can effectively alleviate the impact force, so that the damage to the upper die and the lower die is reduced to a minimum, saving costs, being more practical, and suitable for wide promotion and use.

[0004] This patent directly impacts the lower die through the upper die, but lacks a fixed structure for the part to be stamped. When the upper die is stamping the workpiece, the impact force can easily cause the position of the part to be stamped to shift, resulting in stamping errors. Utility Model Content

[0005] The utility model aims to provide a composite stamping die, which solves the problem that the existing composite stamping dies directly impact the lower die through the upper die, but lacks a fixed structure for the workpiece to be stamped. When the upper die is stamping the workpiece, the impact force easily causes the position of the workpiece to be stamped to shift, resulting in stamping errors.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions: a composite stamping die, comprising a bottom plate, a stamping table is arranged on the bottom plate, a limiting mechanism is arranged on the stamping table, a support column is arranged on the bottom plate, the number of the support columns is two and they are symmetrically arranged, a top plate is arranged on the top of the support column, a cylinder is arranged on the top plate, a movable plate is arranged on the telescopic end of the cylinder, a stamping head is arranged on the movable plate, and the movable plate is slidably connected on the support column;

[0007] The limiting mechanism includes a fixed block, an L-shaped plate and a rotating block. The fixed block is arranged on the stamping table. There are two fixed blocks and they are symmetrically arranged. The L-shaped plate is arranged on the fixed block. There are several L-shaped plates and they are linearly arranged. The rotating block is arranged in the L-shaped plate. The rotating block is cylindrical.

[0008] The above technical scheme is adopted, by setting a bottom plate, a stamping table, a limiting mechanism, a support column, a top plate, a cylinder, a movable plate, and a stamping head. When in use, the bottom plate can first fix the stamping table, and then the top plate is fixed to the bottom plate through the support column. When stamping the part to be stamped, first the part to be stamped is placed on the stamping table, and the limiting mechanism is used to limit and fix the part to be stamped, and then the cylinder is opened to drive the movable plate and the stamping head to move downward to stamp the part to be stamped. Through the setting of the limiting mechanism, the impact force of the stamping head on the part to be stamped can be avoided, causing the position of the part to be stamped to shift, thereby reducing the stamping error. The limiting mechanism includes a fixed block, an L-shaped plate and a rotating block. When in use, the fixed block is first set on the stamping table. When stamping the part to be stamped, the L-shaped plate can limit the part to be stamped to avoid the position shifting when the part to be stamped is subjected to pressure, and the rotating block inside the L-shaped plate can facilitate the movement of the part to be stamped on the stamping table.

[0009] The utility model is further configured as follows: a spring is arranged on the top plate, the springs are several in number and arranged linearly, a pressure plate is arranged at one end of the spring, a through hole is arranged on the pressure plate, the punch head passes through the through hole, a telescopic rod is arranged inside the spring, one end of the telescopic rod is arranged on the top plate, and the other end of the telescopic rod is arranged on the pressure plate.

[0010] By adopting the above technical solution, a spring, a pressure plate, a through hole and a telescopic rod are set. When in use, the pressure plate is connected to the movable plate through the spring. When the cylinder drives the movable plate to move downward, the punching head and the pressure plate will both move downward. After the pressure plate contacts the fixed block, the cylinder continues to drive the movable plate to move downward. At this time, the punching head can punch the part to be stamped, and the movable plate squeezes the spring to deform the spring, thereby avoiding a sudden increase in the punching force and causing damage to the part to be stamped. Then the through hole on the pressure plate can facilitate the punching head to pass through the pressure plate.

[0011] The utility model is further configured as follows: an extension plate is provided on the bottom plate, a limiting groove is provided on the extension plate, a threaded rod is provided inside the limiting groove, one end of the threaded rod extends to the outside of the limiting groove, a sliding block is provided inside the limiting groove, the sliding block is threadedly rotatably connected to the threaded rod, the cross-sections of the limiting groove and the sliding block are both T-shaped, a clamping sleeve is provided on the sliding block, and a handle is provided at one end of the threaded rod.

[0012] By adopting the above technical scheme, an extension plate, a limit groove, a threaded rod, a sliding block, a clamping sleeve and a handle are set. When the stamping part needs to be clamped and fixed, the staff first turns the handle to rotate the threaded rod. Since the sliding block is threadedly rotatably connected to the threaded rod, the sliding block can move on the threaded rod, and the cross-sections of the limit groove and the sliding block are both T-shaped, so that the limit groove can limit the movement of the sliding block, and the sliding block drives the clamping sleeve to move until the clamping sleeve can clamp the stamping part.

[0013] The utility model is further configured as follows: a sliding groove is arranged on the support column, sliding rods are arranged at both ends of the pressure plate, the sliding rods are slidably connected in the sliding groove, and a limiting plate is arranged at one end of the sliding rod.

[0014] By adopting the above technical solution, by setting a sliding groove, a sliding rod and a limit plate, when the pressure plate moves, the sliding rods on both sides of the pressure plate can slide in the sliding groove, thereby limiting the movement of the pressure plate to prevent the pressure plate from shaking, and then the limit plate can limit the sliding rod.

[0015] The utility model is further configured as follows: a first mounting groove is arranged on the fixing block, and a pressure sensor is arranged inside the first mounting groove.

[0016] By adopting the above technical solution, by setting a first mounting groove and a pressure sensor, when in use, the first mounting groove can be used to install the pressure sensor, and the pressure sensor can detect the pressure of the pressure plate on the fixed block, thereby avoiding excessive impact force when the punching head just contacts the workpiece to be processed, causing damage to the workpiece to be stamped.

[0017] The utility model is further configured as follows: a second mounting groove is provided at the bottom of the base plate, an anti-skid pad is provided inside the second mounting groove, and the anti-skid pad is made of rubber material.

[0018] By adopting the above technical solution, by providing the second installation groove and the anti-skid pad, when in use, the second installation groove can install and fix the anti-skid pad, and the anti-skid pad can increase the friction between the base plate and the ground, thereby increasing the stability of the base plate.

[0019] The utility model is further configured as follows: the handle is provided with anti-skid grooves, and the number of the anti-skid grooves is several and arranged in a circle.

[0020] By adopting the above technical solution and providing the anti-skid groove, the anti-skid groove can increase the friction between the staff and the handle during use, so that the handle can be rotated better.

[0021] In summary, the utility model has the following beneficial effects:

[0022] By setting a fixed block, an L-shaped plate and a rotating block, when in use, the fixed block is first set on the stamping table. When the stamping part is being stamped, the L-shaped plate can limit the position of the stamping part to avoid position displacement when the stamping part is subjected to pressure, and the rotating block inside the L-shaped plate can facilitate the movement of the stamping part on the stamping table.

[0023] By setting an extension plate, a limit groove, a threaded rod, a sliding block, a clamping sleeve and a handle, when the stamping part needs to be clamped and fixed, the staff first turns the handle to rotate the threaded rod. Since the sliding block is threadedly rotatably connected to the threaded rod, the sliding block can move on the threaded rod, and the cross-sections of the limit groove and the sliding block are both T-shaped, so that the limit groove can limit the movement of the sliding block, and the sliding block drives the clamping sleeve to move until the clamping sleeve can clamp the stamping part.

[0024] Based on the above improvements, the overall technical effect achieved by the device is that during the stamping process, the stamping parts can be limited and fixed, thereby avoiding the position change of the workpiece due to impact force. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] Brief description of the usage process:

[0045] When in use, first the bottom plate 1 can fix the stamping table 2, and then the top plate 5 is fixed to the bottom plate 1 through the support column 4. When stamping the parts to be stamped, first place the parts to be stamped on the stamping table 2, and then turn on the cylinder 6, so that the cylinder 6 drives the movable plate 7 and the stamping head 8 to move downward to perform stamping processing on the parts to be stamped, wherein the fixed block 301 is arranged on the stamping table 2. When stamping the parts to be stamped, the L-shaped plate 302 can limit the parts to be stamped to avoid the position shifting when the parts to be stamped are subjected to pressure, and the rotating block 303 inside the L-shaped plate 302 can facilitate the movement of the parts to be stamped on the stamping table 2, and can avoid the impact force of the stamping head 8 on the parts to be stamped, causing the position of the parts to be stamped to shift, thereby reducing the stamping error.

[0046] Then, the pressing plate 10 is connected to the moving plate 7 through the spring 9. When the cylinder 6 drives the moving plate 7 to move downward, the punch head 8 and the pressing plate 10 will move downward. After the pressing plate 10 contacts the fixed block 301, the cylinder 6 continues to drive the moving plate 7 to move downward. At this time, the punch head 8 can punch the part to be punched, and the moving plate 7 squeezes the spring 9 to deform the spring 9, thereby avoiding a sudden increase in the punching force and causing damage to the part to be punched. Then, the through hole 11 on the pressing plate 10 can facilitate the punch head 8 to pass through the pressing plate 10;

[0047] Then, when it is necessary to clamp and fix the stamping part, the staff first rotates the handle 18, thereby rotating the threaded rod 15. Since the sliding block 16 is threadedly connected to the threaded rod 15, the sliding block 16 can move on the threaded rod 15, and the cross-sections of the limiting groove 14 and the sliding block 16 are both T-shaped, so that the limiting groove 14 can limit the movement of the sliding block 16, and the sliding block 16 drives the clamping sleeve 17 to move until the clamping sleeve 17 can clamp the stamping part.

[0048] Finally, the first mounting groove 22 can be used to install the pressure sensor 23, which can detect the pressure of the pressure plate 10 on the fixed block 301, thereby preventing the punching head 8 from having excessive impact force when it just contacts the workpiece to be processed, thereby causing damage to the workpiece to be punched. The second mounting groove 24 can be used to install and fix the anti-slip pad 25, which can increase the friction between the base plate 1 and the ground, thereby increasing the stability of the base plate 1.
