Description

Technical Field

[0001] The present invention relates to the technical field of stamping dies, and particularly relates to a stamping die with an accurate guiding function. Background Art

[0002] A stamping die is a tool used in the stamping process to form and process metal sheets or continuous coils through a stamping machine. In the process of mold opening and closing of existing stamping dies, most rely on the guiding columns on the periphery of the die and the guiding sleeves cooperating with the guiding columns for vertical guiding to prevent the die from not fitting properly or having no positioning during the mold opening and closing processes, resulting in inconsistent mold closing positions and affecting each stamping forming.

[0003] However, in the existing structure of the guiding column cooperating with the guiding sleeve, during the up and down movement of the mold opening and closing, over long-term use, the guiding column will gradually deviate. In the initial stage of deviation, it cannot be detected in time, which leads to a period of deviation operation of the device. Operating under deviation for a long time will not only exacerbate the wear of the guiding column, but may also cause damage to the die itself and unqualified products. Summary of the Invention

[0004] The purpose of the present invention is to solve the deficiencies in the prior art and propose a stamping die with an accurate guiding function.

[0005] To achieve the above purpose, the present invention adopts the following technical solution: A stamping die with an accurate guiding function includes an upper die holder and a lower die holder. An upper die body is installed at the bottom of the upper die holder, and a lower die body is installed at the top of the lower die holder near the upper die body. Guide rods are installed at the four corners of the bottom of the upper die holder, and guide grooves are penetrated and opened at the positions of the guide rods on the top of the lower die holder. A first auxiliary mechanism is provided at the guide grooves on the top of the lower die holder, a positioning mechanism is provided inside the guide grooves, and a second auxiliary mechanism is provided below the bottom of the guide grooves.

[0006] Preferably, the first auxiliary mechanism includes rotating blocks, first connecting rods, second connecting rods, and third connecting rods. A plurality of rotating blocks are evenly and movably installed on the outside of the guide grooves on the top of the lower die holder, and the first connecting rods, second connecting rods, and third connecting rods are installed on the outside of the rotating blocks.

[0007] Preferably, moving sliding grooves are opened at the positions of the bottoms of the rotating blocks on the top of the lower die holder, and moving electric sliders are slidably installed inside the moving sliding grooves. The tops of the moving electric sliders are connected to the bottoms of the rotating blocks.

[0008] Preferably, a rotating motor is embedded at the bottom of the rotating block, the installation end of the rotating motor faces downward, and the installation end of the rotating motor is connected to the top of the moving electric slider.

[0009] Preferably, a contact block is installed at one end of the first connecting rod away from the rotating block. A cavity is provided inside the second connecting rod. A spray head is installed at one end of the second connecting rod away from the rotating block. The spray head is communicated with the cavity inside the second connecting rod. A laser distance sensor is installed at one end of the third connecting rod away from the rotating block.

[0010] Preferably, the positioning mechanism includes a guide ring. An annular sliding groove is formed on the inner wall of the guide groove. A guide ring is movably installed inside the guide groove. A movable electric slider is installed on the outer wall of the guide ring close to the annular sliding groove. The movable electric slider is slidably installed inside the annular sliding groove.

[0011] Preferably, a first slot is formed on the inner wall of the guide ring. Two sticking blocks are movably installed inside the first slot. Displacement sliding grooves are formed at the top and bottom of the inner wall of the first slot. Displacement electric sliders are slidably installed inside the displacement sliding grooves. One end of the displacement electric slider close to the sticking block is connected to the sticking block.

[0012] Preferably, the second auxiliary mechanism includes an auxiliary cylinder. The auxiliary cylinder is installed at the bottom of the guide groove. The inner wall of the auxiliary cylinder is communicated with the guide groove. An extrusion block is slidably installed inside the auxiliary cylinder.

[0013] Preferably, a stable sliding groove is formed on the inner wall of the auxiliary cylinder. A stable slider is installed on one side of the extrusion block close to the stable sliding groove. The stable slider is slidably installed inside the stable sliding groove.

[0014] Preferably, a pressure sensor is installed at the bottom end of the inner wall of the auxiliary cylinder. A spring telescopic rod is installed at the bottom of the extrusion block. The bottom of the spring telescopic rod abuts against the top of the pressure sensor.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: In the present invention, by providing a guide rod, a guide ring and a laser distance sensor, during the downward movement of the upper die base and the upper die body, the guide rod is inserted into the guide ring and moves downward. By inserting the guide rod into the guide ring, the guiding effect on the downward movement of the upper die body can be realized, thereby increasing the stamping accuracy of the upper die body and the lower die body. The laser distance sensor rotates to the use position facing the guide rod side. Subsequently, by sliding the movable electric slider in the moving sliding groove, the rotating block moves to the preset use position. In this case, during the up and down movement of the guide rod, it is measured by a plurality of laser distance sensors, and the measured values are transmitted to the background control system for comparison. If there is a deviation between the multiple values, it means that there is an offset when the guide rod moves up and down. At this time, the staff can repair the device according to the measurement results.

[0016] In the present invention, by providing a rotating block, when lubrication operation needs to be performed on the guide rod, the rotating block is driven to rotate by a rotating motor, so that the nozzle rotates to the side facing the guide rod. Lubricating oil is injected into the cavity inside the second connecting rod. The preset booster pump inside the second connecting rod is started, so that the nozzle can spray lubricating oil to the outside of the guide rod. And through this operation method, the guide rod can be lubricated during the operation of the device without stopping the machine, which increases the convenience of using the device; After spraying lubricating oil on the outside of the guide rod, by sliding the displacement electric slider in the displacement chute, the attaching block slides outward. After the attaching block slides to the preset use position, by sliding the movable electric slider in the annular chute, the guide ring rotates inside the guide groove. Thus, when the guide rod moves inside the guide ring, the sponge on the outside of the attaching block can rotate on the outside of the guide rod, which can increase the uniformity of the sprayed lubricating oil on the outside of the guide rod; During the transportation of the device, the upper die base and the lower die base are docked. First, by rotating the rotating block, the abutting block rotates to the side facing the guide rod. Subsequently, by sliding the moving electric slider in the moving chute, the rotating block can move towards the guide rod until the abutting block abuts against the outside of the guide rod. Through this operation method, the fixing of the guide rod inserted in the guide ring can be realized, thereby fixing the upper die base and the lower die base, and preventing the upper die body and the lower die body from shifting during the transportation of the device, causing damage to its interior.

[0017] In the present invention, by providing an auxiliary cylinder, when the guide rod moves into the inside of the auxiliary cylinder, the guide rod will squeeze the squeezing block. After the squeezing block receives the squeezing force, it will slide towards the bottom of the auxiliary cylinder. During the sliding process of the squeezing block, the spring telescopic rod will be squeezed. The spring telescopic rod can absorb the force transmitted by the guide rod to the squeezing block, so as to achieve the use effect of buffering the guide rod, preventing the guide rod from working under a large impact force for a long time, affecting the normal use of the guide rod, and increasing the functional stability of the device; During the use of the device, or just after the device is assembled with the stamping machine, by the way that the guide rod impacts the squeezing block, after the guide rod moves to the preset position, the squeezing force transmitted by the guide rod can be measured by the pressure sensor and transmitted to the background control system. The background control system compares the pressure values measured by multiple pressure sensors. If it is detected that multiple pressure values exceed the standard pressure difference range, it means that there is a direction deviation in the installation between the upper die base and the lower die base. At this time, the staff can repair the device according to the detection result to prevent the device from being damaged due to continuous operation under deviation.

When the laser range finder 17 rotates to the use position facing the guide rod 5, during the up and down movement of the guide rod 5, it is measured by a plurality of laser range finders 17, and the measured values are transmitted to the background control system for comparison. If there is a deviation between the multiple values, it means that there is an offset when the guide rod 5 moves up and down. At this time, the staff can repair the device according to the measurement results; When it is necessary to lubricate the guide rod 5, the spray head 15 is rotated to the side facing the guide rod 5. The spray head 15 can spray oil for lubrication on the outer side of the guide rod 5. And through this operation method, the guide rod 5 can be lubricated during the operation of the device without stopping the machine, which increases the use convenience of the device; During the transportation of the device, the abutting block 13 rotates to the side facing the guide rod 5. Then, by sliding the moving electric slider 11 in the moving chute 10, the rotating block 7 can move towards the guide rod 5 until the abutting block 13 abuts against the outer side of the guide rod 5. Through this operation method, the fixing of the guide rod 5 inserted in the guide ring 9 can be realized, so as to fix the upper die base 1 and the lower die base 2, and prevent the upper die body 3 and the lower die body 4 from shifting during the transportation of the device, resulting in damage to its interior.

[0026] As a technical optimization solution of the present invention, the positioning mechanism includes a guide ring 9. An annular chute 19 is opened on the inner wall of the guide groove 8.

The way that the guide rod 5 is inserted and slid in the guide ring 9 can realize the guiding effect on the downward movement of the upper die body 3, thereby increasing the stamping accuracy of the upper die body 3 and the lower die body 4. The way that the active electric slider 20 slides in the annular chute 19 enables the guide ring 9 to rotate according to different use requirements.

[0027] As a technical optimization solution of the present invention, a first slot 21 is opened on the inner wall of the guide ring 9. Two sticking blocks 22 are movably installed inside the first slot 21. Displacement sliding grooves 23 are opened at the top and bottom of the inner wall of the first slot 21. A displacement electric slider 24 is slidably installed inside the displacement sliding groove 23. One end of the displacement electric slider 24 close to the sticking block 22 is connected to the sticking block 22. By sliding the displacement electric slider 24 in the displacement sliding groove 23, the sticking block 22 can be driven to move inside the inner wall of the guide ring 9 according to the usage requirements.

[0028] As a technical optimization solution of the present invention, the second auxiliary mechanism includes an auxiliary cylinder 6. The auxiliary cylinder 6 is installed at the bottom of the guide groove 8. The inner wall of the auxiliary cylinder 6 is communicated with the guide groove 8. An extrusion block 25 is slidably installed inside the auxiliary cylinder 6. The guide rod 5 extrudes the extrusion block 25, and the extrusion block 25 slides in the auxiliary cylinder 6, so as to achieve buffering of the guide rod 5.

[0029] As a technical optimization solution of the present invention, a stable sliding groove 26 is opened on the inner wall of the auxiliary cylinder 6. A stable slider 27 is installed on one side of the extrusion block 25 close to the stable sliding groove 26. The stable slider 27 is slidably installed inside the stable sliding groove 26. By sliding the stable slider 27 in the stable sliding groove 26, the sliding stability of the extrusion block 25 in the auxiliary cylinder 6 can be increased.

[0030] As a technical optimization solution of the present invention, a pressure sensor 30 is installed at the bottom end of the inner wall of the auxiliary cylinder 6. A spring telescopic rod 29 is installed at the bottom of the extrusion block 25. The bottom of the spring telescopic rod 29 abuts against the top of the pressure sensor 30. The spring telescopic rod 29 can not only achieve buffering of the guide rod 5, but also enable the pressure sensor 30 to detect the extrusion force of the guide rod 5.

[0031] When the present invention is in use, the electrical equipment used in this device is all powered by connecting to an external power supply through wires. This device controls the electrical equipment in the device by presetting a control system. The upper die base 1, the lower die base 2, the upper die body 3 and the lower die body 4 used in this device are all existing mature technologies, and their connection methods are also existing mature technologies. Therefore, no more elaboration will be made on them. The top of the upper die base 1 is connected to the hydraulic rod of the stamping machine, and the bottom of the lower die base 2 is connected to the bottom of the stamping machine. Its installation method is an existing mature technology. Therefore, no more elaboration will be made on it. When the device is in use, the guide rod 5 can be inserted into the inside of the guide ring 9 and extend into the inside of the auxiliary cylinder 6. A booster pump is provided in the inner cavity of the second connecting rod 14. A sponge can be installed on the outside of the sticking block 22. A rubber pad is provided on the side of the abutting block 13 away from the first connecting rod 12.

[0032] When the device is in use, the punching machine drives the upper die holder 1 and the upper die body 3 to move downward. During the downward movement of the upper die holder 1 and the upper die body 3, the guide rod 5 is inserted into the inside of the guide ring 9 and moves downward. By inserting the guide rod 5 into the guide ring 9, the guiding effect on the downward movement of the upper die body 3 can be realized, thereby increasing the punching accuracy of the upper die body 3 and the lower die body 4; When the guide rod 5 moves into the inside of the auxiliary cylinder 6, the guide rod 5 will squeeze the extrusion block 25. After receiving the extrusion force, the extrusion block 25 will slide towards the bottom of the auxiliary cylinder 6. During the sliding process of the extrusion block 25, it will squeeze the spring telescopic rod 29. The spring telescopic rod 29 can absorb the force transmitted from the guide rod 5 to the extrusion block 25, thereby achieving the use effect of buffering the guide rod 5, preventing the guide rod 5 from working under a large impact force for a long time, affecting the normal use of the guide rod 5, and increasing the functional stability of the device; During the use of the device, or just after the device is assembled with the punching machine, by the way that the guide rod 5 impacts the extrusion block 25, after the guide rod 5 moves to the preset position, the extrusion force transmitted by the guide rod 5 can be measured through the pressure sensor 30 and transmitted to the background control system. The background control system compares the pressure values measured by multiple pressure sensors 30. If it is detected that multiple pressure values exceed the standard pressure difference range, it means that there is a direction deviation in the installation between the upper die holder 1 and the lower die holder 2. At this time, the staff can repair the device according to the detection result to prevent the device from being damaged due to continuous operation under deviation.

[0033] When it is necessary to detect the deviation of the guide rod 5, the rotating motor 18 drives the rotating block 7 to rotate, so that the laser ranging sensor 17 rotates to the use position facing the guide rod 5. Subsequently, by sliding the moving electric slider 11 in the moving chute 10, the rotating block 7 is moved to the preset use position. In this case, during the up and down movement of the guide rod 5, it is measured by multiple laser ranging sensors 17 and the measured values are transmitted to the background control system for comparison. If there is a deviation between multiple values, it means that there is a deviation when the guide rod 5 moves up and down. At this time, the staff can repair the device according to the measurement result.

[0034] When it is necessary to lubricate the guide rod 5, the rotating motor 18 drives the rotating block 7 to rotate, so that the nozzle 15 rotates to the side facing the guide rod 5. Lubricating oil is injected into the cavity inside the second connecting rod 14. The preset booster pump inside the second connecting rod 14 is started, so that the nozzle 15 can spray lubricating oil to the outside of the guide rod 5. And by this operation method, the guide rod 5 can be lubricated during the operation of the device without stopping the machine, increasing the use convenience of the device; After lubricating the outside of the guide rod 5 by spraying oil, through the sliding of the displacement electric slider 24 in the displacement chute 23, the attachment block 22 slides outward. After the attachment block 22 slides to the preset use position, through the sliding of the movable electric slider 20 in the annular chute 19, the guide ring 9 rotates inside the guide groove 8, so that when the guide rod 5 moves inside the guide ring 9, the sponge on the outside of the attachment block 22 can rotate on the outside of the guide rod 5, which can increase the uniformity of the lubricating oil sprayed on the outside of the guide rod 5.

[0035] During the transportation of the device, the upper die base 1 and the lower die base 2 are docked in the Figure 1 shown manner. First, by rotating the rotating block 7, the abutting block 13 rotates to the side facing the guide rod 5. Subsequently, through the sliding of the moving electric slider 11 in the moving chute 10, the rotating block 7 can move towards the guide rod 5 until the abutting block 13 abuts against the outside of the guide rod 5. Through this operation method, the fixing of the guide rod 5 inserted in the guide ring 9 can be realized, thereby fixing the upper die base 1 and the lower die base 2, and preventing the upper die body 3 and the lower die body 4 from shifting during the transportation of the device, causing damage to its interior.

[0036] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent replacements or changes, and should be covered within the protection scope of the present invention.
