Description

Technical Field

[0001] The utility model belongs to the technical field of stamping die design, and particularly relates to a stamping die which is convenient for disassembling and assembling a stamping die head. Background Technique

[0002] A stamping die is a tool used in stamping processing. It is used to apply pressure to a metal sheet through a stamping machine to deform or separate it, so as to obtain parts with the required shape and size. The design and manufacture of stamping dies are key links in the stamping process, directly affecting product quality, production efficiency and cost.

[0003] In the existing stamping die, the disassembly and assembly of the punch head are relatively troublesome and not convenient for maintenance. After stamping, the die is easily stuck in the bottom die, affecting the processing progress. At the same time, there is a lack of a design for automatically collecting formed parts, and the processing fluency is not high. Summary of the Invention

[0004] The purpose of the utility model is to provide a stamping die which is convenient for disassembling and assembling a stamping die head, so as to solve the problems existing in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A stamping die which is convenient for disassembling and assembling a stamping die head includes a support device. A stamping die device is arranged on the top of the support device, and a guiding device is arranged at the bottom of the stamping die device; the stamping die device includes a pressing seat. Two hydraulic cylinders are symmetrically installed on the top of the pressing seat. An installation table is arranged above the hydraulic cylinders. A punch is slidably arranged at the bottom of the pressing seat. A plurality of locking bolts are symmetrically arranged on both sides of the punch. Two outer shells are symmetrically arranged on both sides of the pressing seat. An electromagnet is arranged inside the outer shell; the guiding device includes an inclined plate. Two springs are symmetrically and fixedly arranged on the back of the inclined plate. A traction wire is arranged in the middle of the inclined plate.

[0007] Further: The support device includes a support seat. A first pulley is rotatably arranged at the back of the support seat. Two second pulleys are symmetrically and rotatably arranged on the top of the support seat. Two guide rails are symmetrically and fixedly arranged in the middle of the support seat. A bottom die is arranged at the bottom of the support seat.

[0008] Further: The pressing seat is bolted to the hydraulic cylinder.

[0009] Further: The outer shell is square tube-shaped.

[0010] Further: The traction wire respectively bypasses the first pulley and the second pulley.

[0011] Further: The cross-section of the guide rail is circular, and the inclined plate is slidably connected with the guide rail.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] During stamping, first place the original part to be stamped on the bottom die. The support hydraulic cylinder of the installation table extends, driving the lower pressure seat and the punch to descend. During the downward movement of the lower pressure seat, the traction wire is pulled downward. The traction wire pulls the inclined plate to move backward under the support of the first pulley and the second pulley. The guide rail limits and supports the movement of the inclined plate while the spring is compressed. After the inclined plate moves backward, it no longer blocks the fall of the punch. The punch stamps the part on the top of the bottom die. At the same time, the electromagnet inside the housing is turned on, generating a magnetic force to adsorb the stamped workpiece. After stamping, the hydraulic cylinder resets, driving the punch and the adsorbed workpiece to rise, realizing the demoulding of the workpiece. At the same time, the traction wire loses the top tension and no longer pulls the inclined plate. The support seat supports the spring to push the inclined plate to reset and move back under the punch. Finally, the electromagnet is turned off, and the workpiece falls onto the inclined plate and slides along it, completing the collection of the formed workpiece. Through the design of setting electromagnets on both sides of the lower pressure seat, the workpiece is driven out after stamping, preventing the workpiece from being stuck in the bottom die and difficult to take out. At the same time, it cooperates with the moving inclined plate to complete the automatic collection of the formed workpiece, improving the processing fluency;

[0014] Through the design of setting the traction wire on the lower pressure seat, the movement of the inclined plate is controlled by the lifting of the lower pressure seat, improving the linkage of the device, facilitating the saving of manufacturing costs, and further enhancing the automation degree of the device;

[0015] First, the punch is inserted into the bottom of the lower pressure seat through the T-shaped structure on the top, and then the locking bolts are screwed into both sides of the lower pressure seat respectively to connect the lower pressure seat and the punch together, completing the fixation of the punch and realizing the quick disassembly and assembly of the punch.

[0025] Please refer to Figures 1 - 4, a stamping die facilitating disassembly and assembly of a stamping die head, comprising a support device 1. A die stamping device 2 is arranged on the top of the support device 1, and a guiding device 3 is arranged at the bottom of the die stamping device 2.

[0026] In this embodiment: The support device 1 includes a support base 101. A first pulley 102 is rotatably arranged behind the support base 101. Two second pulleys 103 are symmetrically and rotatably arranged on the top of the support base 101. Two guide rails 104 are symmetrically and fixedly arranged in the middle of the support base 101. A bottom die 105 is arranged at the bottom of the support base 101. The cross-section of the guide rail 104 is circular, and the inclined plate 301 is slidably connected to the guide rail 104. During stamping processing, first place the original part to be stamped on the bottom die 105;

[0027] In this embodiment: The die stamping device 2 includes a downward pressure seat 201. Two hydraulic cylinders 202 are symmetrically installed on the top of the downward pressure seat 201. An installation platform 203 is arranged above the hydraulic cylinders 202. A punch 204 is slidably arranged at the bottom of the downward pressure seat 201. A number of locking bolts 205 are symmetrically arranged on both sides of the punch 204. Two outer shells 206 are symmetrically arranged on both sides of the downward pressure seat 201. An electromagnet 207 is arranged inside the outer shell 206. The downward pressure seat 201 is bolted to the hydraulic cylinder 202. The outer shell 206 is square tube-shaped. The installation platform 203 is installed on the ceiling. First, the punch 204 is inserted into the bottom of the downward pressure seat 201 through the T-shaped structure at the top, and then the locking bolts 205 are screwed into the downward pressure seat 201 along both sides respectively to connect the downward pressure seat 201 and the punch 204 together, completing the fixation of the punch 204 and realizing the quick disassembly and assembly of the punch 204. The installation platform 203 supports the elongation of the hydraulic cylinder 202, driving the downward pressure seat 201 and the punch 204 to descend. During the downward movement of the downward pressure seat 201, the traction wire 303 is pulled downward. The punch 204 stamps the original part on the top of the bottom die 105. At the same time, the electromagnet 207 inside the outer shell 206 is turned on to generate a magnetic force to adsorb the stamped workpiece. After stamping, the hydraulic cylinder 202 resets to drive the punch 204 and the adsorbed workpiece to rise, realizing the demoulding of the workpiece. Through the design of arranging the electromagnet 207 on both sides of the downward pressure seat 201, the workpiece is driven out after stamping, preventing the workpiece from being stuck in the bottom die 105 and being difficult to take out. At the same time, it cooperates with the moving inclined plate 301 to complete the automatic collection of the formed workpiece, improving the processing fluency;

[0028] In this embodiment: The guiding device 3 includes an inclined plate 301. Two springs 302 are symmetrically and fixedly arranged on the rear surface of the inclined plate 301. A traction wire 303 is arranged in the middle of the inclined plate 301. The traction wire 303 bypasses the first pulley 102 and the second pulley 103 respectively. The traction wire 303 pulls the inclined plate 301 to move backward under the support of the first pulley 102 and the second pulley 103. The guide rail 104 limits and supports the movement of the inclined plate 301 while the spring 302 is compressed. After the inclined plate 301 moves backward, it no longer blocks the downward movement of the punch 204. The traction wire 303 loses the top tension and no longer pulls the inclined plate 301. The support base 101 supports the spring 302, and the spring force pushes the inclined plate 301 to reset and move back under the punch 204 again. Finally, the electromagnet 207 is turned off, and the workpiece falls onto the inclined plate 301 and slides along it, completing the collection of the formed workpiece. Through the design of arranging the traction wire 303 on the lower pressing seat 201, the movement of the inclined plate 301 is controlled by the lifting of the lower pressing seat 201, improving the linkage of the device, facilitating the saving of manufacturing costs, and further enhancing the automation degree of the device.

[0029] Working principle: The installation table 203 is installed on the ceiling. First, the punch 204 is inserted into the bottom of the lower pressing seat 201 through the top T-shaped structure and then slid. Then, the locking bolts 205 are screwed into both sides of the lower pressing seat 201 respectively to connect the lower pressing seat 201 and the punch 204 together, completing the fixation of the punch 204 and realizing the quick disassembly and assembly of the punch 204. During stamping, first place the element to be stamped on the bottom die 105. The installation table 203 supports the hydraulic cylinder 202 to extend, driving the lower pressing seat 201 and the punch 204 to descend. During the descent of the lower pressing seat 201, the traction wire 303 is pulled downward. The traction wire 303 pulls the inclined plate 301 to move backward under the support of the first pulley 102 and the second pulley 103. The guide rail 104 limits and supports the movement of the inclined plate 301 while the spring 302 is compressed. After the inclined plate 301 moves backward, it no longer blocks the downward movement of the punch 204. The punch 204 stamps the element on the top of the bottom die 105. At the same time, the electromagnet 207 inside the housing 206 is turned on to generate a magnetic force to adsorb the stamped workpiece. After stamping, the hydraulic cylinder 202 resets and drives the punch 204 and the adsorbed workpiece to rise, realizing the demoulding of the workpiece. At the same time, the traction wire 303 loses the top tension and no longer pulls the inclined plate 301. The support base 101 supports the spring 302, and the spring force pushes the inclined plate 301 to reset and move back under the punch 204 again. Finally, the electromagnet 207 is turned off, and the workpiece falls onto the inclined plate 301 and slides along it, completing the collection of the formed workpiece. Through the design of arranging the electromagnet 207 on both sides of the lower pressing seat 201, the workpiece is driven to be ejected after stamping, preventing the workpiece from being stuck in the bottom die 105 and being difficult to take out. At the same time, it cooperates with the moving inclined plate 301 to complete the automatic collection of the formed workpiece, improving the processing fluency. Through the design of arranging the traction wire 303 on the lower pressing seat 201, the movement of the inclined plate 301 is controlled by the lifting of the lower pressing seat 201, improving the linkage of the device, facilitating the saving of manufacturing costs, and further enhancing the automation degree of the device.
