Description

Technical Field

[0001] This utility model relates to the field of stamping equipment technology, and in particular to a high-speed switching multi-functional stamping die. Background Technology

[0002] Stamping dies are special process equipment used in cold stamping to process materials (metal or non-metal) into parts (or semi-finished products). They are called cold stamping dies (commonly known as cold stamping dies). Stamping is a pressure processing method that uses dies mounted on a press to apply pressure to materials at room temperature, causing them to separate or plastically deform, thereby obtaining the desired parts.

[0003] Patent document CN112517754B discloses a precision stamping die capable of rapid switching, including a mounting base. A T-shaped groove is formed along the width direction on the top outer wall of the mounting base, and a T-shaped slider is slidably mounted within the groove. A lower die is welded to the top outer wall of the slider, and an installation opening is formed on the top outer wall of the lower die. Two nitrogen springs are fixedly connected to the bottom inner wall of the installation opening on the top of the lower die. A lifting plate is slidably mounted on the top inner wall of the lower die, and its bottom ends are welded to the top outer walls of the two nitrogen springs respectively. Fixing plates are welded to both outer walls of the lower die, and grooves are formed on the opposite outer walls of the two fixing plates. This invention simplifies the fixing operation, enabling rapid fixing of the lower die, improving fixing efficiency. When changing the die, it eliminates the need to sequentially replace the upper and lower dies, allowing for rapid die replacement and improving replacement efficiency.

[0004] The above solution uses screws and fixing blocks to press the mold against the inner wall of the fixing frame to fix the mold. However, this fixing method cannot guarantee that molds of different specifications can be accurately located directly below the stamping machine, resulting in the mold and the punch of the stamping machine not being on the same vertical line, which in turn affects the subsequent stamping operation. Utility Model Content

[0005] This utility model discloses a high-speed switching multi-functional stamping die, which aims to solve the technical problem of inconvenient replacement of stamping dies in existing stamping equipment.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A high-speed switching multi-functional stamping die includes a base and a die body. An L-shaped top plate is installed on the upper surface of the base. A hydraulic press is embedded on the upper surface of the L-shaped top plate. The telescopic end of the hydraulic press extends to the inner top of the L-shaped top plate and is fixedly installed with a connecting plate. A stamping head is installed on the lower surface of the connecting plate. A die fixing mechanism is provided on the upper surface of the base.

[0008] The mold fixing mechanism includes a cross-shaped mounting groove on the upper surface of the base. The inner wall of the cross-shaped mounting groove is rotatably connected to four threaded rods arranged in a circumferential array. A motor is installed on the lower surface of the base. The output shaft of the motor extends into the interior of the cross-shaped mounting groove and is fixedly connected to a drive bevel gear. The opposite ends of the four threaded rods are all fixedly connected to driven bevel gears corresponding to the drive bevel gears. Threaded blocks are threadedly connected to the surface of the threaded rods. A clamping plate is fixedly installed on the upper surface of the threaded blocks.

[0009] In a preferred embodiment, the driving bevel gear and the driven bevel gear mesh with each other, and the output shaft of the motor is connected to four threaded rods via the driving bevel gear and the driven bevel gear respectively.

[0010] In a preferred embodiment, anti-slip pads are embedded on the opposite surfaces of the four clamps, and the anti-slip pads are made of wear-resistant rubber.

[0011] The anti-slip pads improve the stability of the clamping plate after it comes into contact with the mold body.

[0012] In a preferred embodiment, the lower surface of the threaded block is provided with a guide slider, and the inner bottom wall of the cross-shaped mounting groove is provided with a guide groove for the guide slider to slide.

[0013] By setting a guide slider, the threaded block can drive the clamping plate to move in a specific direction through the rotation of the threaded rod.

[0014] In a preferred embodiment, a sealing cylinder is embedded on the upper surface of the L-shaped top plate. The inner bottom wall of the sealing cylinder has a sliding opening that extends through to the inner top wall of the L-shaped top plate. An L-shaped transmission rod extending into the sealing cylinder is fixedly installed on the back of the connecting plate through the sliding opening. A piston is installed at one end of the L-shaped transmission rod inside the sealing cylinder. A telescopic nozzle is embedded in the inner front wall of the L-shaped top plate. An air inlet pipe and an air delivery pipe are embedded in the upper end of the sealing cylinder. The end of the air delivery pipe away from the sealing cylinder is connected to the telescopic nozzle.

[0015] By using a sealed cylinder and piston, the workpiece that has just been stamped can be cooled by blowing air.

[0016] In a preferred embodiment, a one-way intake valve is embedded on the surface of the intake pipe, and a one-way exhaust valve is embedded on the surface of the delivery pipe.

[0017] In a preferred embodiment, a stamping groove is provided on the upper surface of the mold body, and a plurality of four springs arranged in a circumferential array are installed on the inner bottom wall of the stamping groove, with a push plate fixedly connected to the upper end of the springs.

[0018] The spring and push plate can push the workpiece out of the stamping groove, making it easy to discharge.

[0019] In a preferred embodiment, the lower surface of the base is fitted with four support legs arranged in a rectangular array.

[0020] As can be seen from the above, the high-speed switching multi-functional stamping die provided by this utility model has the following technical effects.

[0021] Firstly, under the operation of the motor, the four threaded rods are driven to rotate simultaneously by the active and driven bevel gears. Under the guidance of the guide slider, the four threaded blocks drive the four clamping plates to move in a directional manner through the rotation of the threaded rods. This causes the four clamping plates to retract and clamp the mold body, thus fixing the mold body directly below the stamping head. This facilitates mold replacement and provides a guarantee for subsequent stamping operations.

[0022] Secondly, during the stamping process, the sheet metal to be stamped is placed on the mold body. At this time, the operation of the hydraulic press drives the connecting plate and the stamping head to descend and complete the stamping operation through the stamping groove. During this period, under the action of the spring, the workpiece formed in the stamping groove is pushed out of the stamping groove by the push plate, avoiding the workpiece from being embedded in the stamping groove and facilitating its unloading.

[0023] Thirdly: After the stamping operation is completed, the hydraulic press drives the connecting plate and the stamping head to retract and reset. The upward movement of the connecting plate drives the L-shaped transmission rod and the piston to move upward synchronously inside the sealed cylinder. The upward movement of the piston sends the air pressure inside the sealed cylinder into the telescopic nozzle through the air supply pipe. The airflow blown out by the telescopic nozzle can cool down the workpiece that has just been stamped, preventing the heat of the workpiece from causing burns to personnel, and further improving the practicality of the device.

[0032] The lower surface of the base 1 is equipped with four support legs arranged in a rectangular array.

[0033] The mold fixing mechanism includes a cross-shaped mounting groove on the upper surface of the base 1. The inner wall of the cross-shaped mounting groove is rotatably connected to four threaded rods 7 arranged in a circumferential array. A motor 8 is mounted on the lower surface of the base 1. The output shaft of the motor 8 extends into the interior of the cross-shaped mounting groove and is fixedly connected to a drive bevel gear 9. The opposite ends of the four threaded rods 7 are fixedly connected to driven bevel gears 10 corresponding to the drive bevel gears 9. Threaded blocks 11 are threadedly connected to the surface of the threaded rods 7. A clamping plate 12 is fixedly mounted on the upper surface of the threaded blocks 11.

[0034] The driving bevel gear 9 and the driven bevel gear 10 mesh with each other, and the output shaft of the motor 8 is connected to the four threaded rods 7 through the driving bevel gear 9 and the driven bevel gear 10 respectively.

[0035] Anti-slip pads are embedded on the opposite surfaces of the four clamping plates 12. The anti-slip pads are made of wear-resistant rubber. The anti-slip pads can improve the stability of the clamping plates 12 after they come into contact with the mold body 2.

[0036] The lower surface of the threaded block 11 is provided with a guide slider 13, and the inner bottom wall of the cross-shaped mounting groove is provided with a guide groove for the guide slider 13 to slide. Under the guidance of the guide slider 13, the threaded block 11 can drive the clamping plate 12 to move in a directional manner through the rotation of the threaded rod 7.

[0037] Reference Figure 1 and Figure 5 In a preferred embodiment, a sealing cylinder 14 is embedded on the upper surface of the L-shaped top plate 3. The inner bottom wall of the sealing cylinder 14 has a sliding opening that extends through to the inner top wall of the L-shaped top plate 3. An L-shaped transmission rod 15 extending into the interior of the sealing cylinder 14 is fixedly installed on the back of the connecting plate 5 through the sliding opening. A piston 16 is installed at one end of the L-shaped transmission rod 15 inside the sealing cylinder 14. A telescopic nozzle 17 is embedded in the inner front wall of the L-shaped top plate 3. An air inlet pipe 18 and an air delivery pipe 19 are respectively embedded in the upper end of the sealing cylinder 14.

[0038] A one-way air intake valve is embedded on the surface of the air intake pipe 18, and a one-way air outlet valve is embedded on the surface of the air delivery pipe 19.

[0039] By using the sealing cylinder 14 and piston 16, the workpiece that has just been stamped can be cooled by blowing air.

[0042] Working principle: The mold body 2 to be switched is placed on the base 1. Under the operation of the motor 8, the four threaded rods 7 are rotated simultaneously by the driving bevel gear 9 and the driven bevel gear 10. Under the guidance of the guide slider 13, the four threaded blocks 11 drive the four clamping plates 12 to move in a direction through the rotation of the threaded rods 7, so that the four clamping plates 12 retract and clamp and fix the mold body 2. Thus, the mold body 2 is fixed directly below the stamping head 6. During the stamping process, the sheet metal to be stamped is placed on the mold body 2. At this time, the operation of the hydraulic press 4 drives the connecting plate 5 and the stamping head 6 to descend and pass through the stamping plate. After the stamping operation is completed, the workpiece formed in the stamping groove is pushed out of the stamping groove by the push plate 21 under the action of the spring 20, so as to avoid the workpiece being embedded in the stamping groove. After the stamping operation is completed, the hydraulic press 4 drives the connecting plate 5 and the stamping head 6 to retract and reset. The upward movement of the connecting plate 5 drives the L-shaped transmission rod 15 and the piston 16 to move upward synchronously in the sealing cylinder 14. The upward movement of the piston 16 sends the air pressure in the sealing cylinder 14 into the telescopic nozzle 17 through the air supply pipe 19 and blows it out. The airflow blown out by the telescopic nozzle 17 can cool down the workpiece that has just been stamped, so as to avoid the heat of the workpiece causing burns to personnel.
