Description

Technical Field

[0001] This invention relates to the field of stamping die technology, and in particular to a stamping die with a precise guiding function. Background Technology

[0002] A stamping die is a tool used in stamping processes to form and process sheet metal or continuous coils using a stamping press. Most existing stamping dies rely on guide posts and guide sleeves around the die's perimeter for vertical guidance during opening and closing. This prevents the die from misalignment or lack of positioning during these processes, ensuring consistent die placement and preventing issues with stamping success.

[0003] However, in the existing structure of guide pillars and guide sleeves, the guide pillars will gradually deviate during the opening and closing and up and down movement of the mold. In the early stages of the deviation, it cannot be detected in time, which leads to a period of deviation operation of the device. Long-term operation under deviation will not only aggravate the wear of the guide pillars, but also cause damage to the mold itself and unqualified products in severe cases. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a stamping die with precise guiding function.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A stamping die with precise guiding function includes an upper die base and a lower die base. An upper die body is installed at the bottom of the upper die base, and a lower die body is installed at the top of the lower die base near the upper die body. Guide rods are installed at the four corners of the bottom of the upper die base. A guide groove is formed through the guide rods at the top of the lower die base. A first auxiliary mechanism is provided at the guide groove at the top of the lower die base. A positioning mechanism is provided inside the guide groove. A second auxiliary mechanism is provided below the bottom of the guide groove.

[0007] Preferably, the first auxiliary mechanism includes a rotating block, a first connecting rod, a second connecting rod, and a third connecting rod. Multiple rotating blocks are evenly and movably installed on the top of the lower mold base outside the guide groove, and the first connecting rod, the second connecting rod, and the third connecting rod are installed on the outside of the rotating blocks.

[0008] Preferably, a movable slide groove is provided on the top of the lower mold base at the bottom of the rotating block, and a movable electric slider is slidably installed inside the movable slide groove, with the top of the movable electric slider connected to the bottom of the rotating block.

[0009] Preferably, a rotary motor is embedded in the bottom of the rotating block, with the mounting end of the rotary motor facing downwards and connected to the top of the movable electric slider.

[0010] Preferably, the end of the first connecting rod away from the rotating block is equipped with an abutment block, the second connecting rod has a cavity inside, a nozzle is installed at the end of the second connecting rod away from the rotating block, the nozzle is connected to the cavity inside the second connecting rod, and a laser rangefinder is installed at the end of the third connecting rod away from the rotating block.

[0011] Preferably, the positioning mechanism includes a guide ring, an annular groove is formed on the inner wall of the guide groove, the guide ring is movably installed inside the guide groove, and a movable electric slider is installed on the outer wall of the guide ring near the annular groove, the movable electric slider is slidably installed inside the annular groove.

[0012] Preferably, a first groove is formed on the inner wall of the guide ring, and two blocks are movably installed inside the first groove. Displacement grooves are formed at the top and bottom of the inner wall of the first groove, and displacement electric sliders are slidably installed inside the displacement grooves. The end of the displacement electric slider near the block is connected to the block.

[0013] Preferably, the second auxiliary mechanism includes an auxiliary cylinder, the bottom of the guide groove is equipped with the auxiliary cylinder, the inner wall of the auxiliary cylinder is connected to the guide groove, and an extrusion block is slidably installed inside the auxiliary cylinder.

[0014] Preferably, a stabilizing groove is provided on the inner wall of the auxiliary cylinder, and a stabilizing slider is installed on the side of the extrusion block near the stabilizing groove, with the stabilizing slider slidably installed inside the stabilizing groove.

[0015] Preferably, a pressure sensor is installed at the bottom of the inner wall of the auxiliary cylinder, and a spring telescopic rod is installed at the bottom of the extrusion block, with the bottom of the spring telescopic rod abutting against the top of the pressure sensor.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] In this invention, by setting a guide rod, a guide ring and a laser rangefinder, the guide rod is inserted into the inside of the guide ring and moves downward during the downward movement of the upper die base and the upper die body. By inserting the guide rod into the guide ring, the downward movement of the upper die body can be guided, thereby increasing the stamping accuracy of the upper die body and the lower die body.

[0018] The laser rangefinder rotates to the position facing the guide rod. Then, the rotating block moves to the preset position by sliding the electric slider in the sliding groove. During this process, multiple laser rangefinders measure the guide rod as it moves up and down, and the measured values ​​are transmitted to the back-end control system for comparison. If there is a deviation between the multiple values, it indicates that there is an offset when the guide rod moves up and down. At this time, the staff can inspect the device based on the measurement results.

[0019] In this invention, a rotating block is provided. When the guide rod needs to be lubricated, a rotary motor drives the rotating block to rotate, causing the nozzle to rotate to the side facing the guide rod. Lubricating oil is injected into the cavity inside the second connecting rod, and the pre-set booster pump inside the second connecting rod is activated, allowing the nozzle to spray oil to the outside of the guide rod for lubrication. Moreover, through this operation method, the guide rod can be lubricated during the operation of the device without stopping the machine, which increases the ease of use of the device.

[0020] After the guide rod is lubricated by spraying oil on the outside, the pad slides outward by sliding the displacement electric slider in the displacement groove. After the pad slides to the preset position, the guide ring rotates inside the guide groove by sliding the movable electric slider in the annular groove. This allows the sponge on the outside of the pad to rotate on the outside of the guide rod when the guide rod moves inside the guide ring, which can increase the uniformity of the lubricating oil sprayed on the outside of the guide rod.

[0021] During transportation, the upper and lower mold bases are connected. First, the rotating block rotates to make the abutment block face the guide rod. Then, the sliding of the movable electric slider in the sliding groove allows the rotating block to move towards the guide rod until the abutment block abuts against the outside of the guide rod. This operation method can fix the guide rod inserted into the guide ring, thereby fixing the upper and lower mold bases and preventing the upper and lower mold bodies from shifting during transportation, which could cause internal damage.

[0022] In this invention, an auxiliary cylinder is provided. When the guide rod moves into the interior of the auxiliary cylinder, the guide rod will squeeze the squeezing block. After being squeezed, the squeezing block will slide towards the bottom of the auxiliary cylinder. During the sliding process, the squeezing block will squeeze the spring telescopic rod. The spring telescopic rod can absorb the force transmitted from the guide rod to the squeezing block, thereby achieving a buffering effect on the guide rod, preventing the guide rod from working under large impact forces for a long time, which would affect the normal use of the guide rod and increase the functional stability of the device.

[0023] During use, or immediately after assembly with the press, the device moves to a preset position by striking the extrusion block with a guide rod. A pressure sensor measures the extrusion force transmitted by the guide rod and transmits it to the back-end control system. The back-end control system compares the pressure values ​​measured by multiple pressure sensors. If multiple pressure values ​​exceed the standard pressure difference range, it indicates a directional deviation in the installation between the upper and lower die bases. At this point, personnel can inspect the device based on the detection results to prevent damage caused by continued operation under deviation. Attached Figure Description

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0036] Reference Figure 1-10A stamping die with precise guiding function includes an upper die holder 1 and a lower die holder 2. An upper die body 3 is mounted on the bottom of the upper die holder 1, and a lower die body 4 is mounted on the top of the lower die holder 2 near the upper die body 3. Guide rods 5 are mounted at the four corners of the bottom of the upper die holder 1. A guide groove 8 is formed through the guide rods 5 on the top of the lower die holder 2. A first auxiliary mechanism is provided on the top of the lower die holder 2 at the guide groove 8. A positioning mechanism is provided inside the guide groove 8, and a second auxiliary mechanism is provided below the bottom of the guide groove 8. The guide rods 5 and the positioning mechanism can guide the upper die holder 1 and the lower die holder 2, thereby increasing the stamping accuracy of the upper die body 3 and the lower die body 4. The first auxiliary mechanism can detect the offset of the guide rods 5 during use, fix the guide rods 5, and lubricate the guide rods 5 with oil. The second auxiliary mechanism can provide a buffering effect for the guide rods 5.

[0037] As a technical optimization of the present invention, the first auxiliary mechanism includes a rotating block 7, a first connecting rod 12, a second connecting rod 14, and a third connecting rod 16. Multiple rotating blocks 7 are evenly and movably mounted on the top of the lower mold base 2 outside the guide groove 8. The first connecting rod 12, the second connecting rod 14, and the third connecting rod 16 are mounted on the outer side of the rotating blocks 7. By rotating the rotating blocks 7, different functions on the first connecting rod 12, the second connecting rod 14, and the third connecting rod 16 can be switched.

[0038] As a technical optimization of the present invention, a movable slide groove 10 is provided on the top of the lower mold base 2 at the bottom position of the rotating block 7. A movable electric slider 11 is slidably installed inside the movable slide groove 10, and the top of the movable electric slider 11 is connected to the bottom of the rotating block 7. By sliding the movable electric slider 11 in the movable slide groove 10, the rotating block 7 can be moved on the top of the lower mold base 2 according to different usage requirements.

[0039] As a technical optimization of the present invention, a rotary motor 18 is embedded in the bottom of the rotating block 7, with the mounting end of the rotary motor 18 facing downwards and connected to the top of the movable electric slider 11. The rotary motor 18 can drive the rotating block 7 to rotate according to different usage requirements.

[0040] As a technical optimization of the present invention, a stop block 13 is installed at the end of the first connecting rod 12 away from the rotating block 7. A cavity is provided inside the second connecting rod 14, and a nozzle 15 is installed at the end of the second connecting rod 14 away from the rotating block 7, communicating with the cavity inside the second connecting rod 14. A laser rangefinder 17 is installed at the end of the third connecting rod 16 away from the rotating block 7. When the laser rangefinder 17 rotates to a position facing the guide rod 5, and the guide rod 5 moves up and down, multiple laser rangefinders 17 measure its movement and transmit the measured values ​​to the background control system for comparison. If there is a deviation among the multiple values, it indicates that the guide rod 5 is offset during its up and down movement. At this time, the operator can inspect the device based on the measurement results.

[0041] When the guide rod 5 needs to be lubricated, the nozzle 15 is rotated to face the guide rod 5. The nozzle 15 can spray oil to lubricate the outside of the guide rod 5. In this way, the guide rod 5 can be lubricated during the operation of the device without stopping the machine, which increases the ease of use of the device.

[0042] During transportation, the abutment block 13 rotates to face the guide rod 5. Then, by moving the electric slider 11 in the sliding groove 10, the rotating block 7 can move towards the guide rod 5 until the abutment block 13 abuts against the outside of the guide rod 5. Through this operation, the guide rod 5 can be fixed in the guide ring 9, thereby fixing the upper mold base 1 and the lower mold base 2. This prevents the upper mold body 3 and the lower mold body 4 from shifting during transportation, which could cause internal damage.

[0043] As an optimized technical solution of the present invention, the positioning mechanism includes a guide ring 9, an annular groove 19 is formed on the inner wall of the guide groove 8, the guide ring 9 is movably installed inside the guide groove 8, and a movable electric slider 20 is installed on the outer wall of the guide ring 9 near the annular groove 19. The movable electric slider 20 is slidably installed inside the annular groove 19. The guide rod 5 slides and inserts into the guide ring 9, which can guide the upper die body 3 to move downward, thereby increasing the stamping accuracy of the upper die body 3 and the lower die body 4. The movable electric slider 20 slides in the annular groove 19, allowing the guide ring 9 to rotate according to different usage requirements.

[0044] As a technical optimization of the present invention, a first slot 21 is formed on the inner wall of the guide ring 9. Two pads 22 are movably installed inside the first slot 21. Displacement grooves 23 are formed at both the top and bottom of the inner wall of the first slot 21. A displacement electric slider 24 is slidably installed inside the displacement groove 23. The end of the displacement electric slider 24 near the pad 22 is connected to the pad 22. By sliding the displacement electric slider 24 in the displacement groove 23, the pads 22 can be moved within the inner wall of the guide ring 9 according to the usage requirements.

[0045] As a technical optimization 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, and the inner wall of the auxiliary cylinder 6 is connected to 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, which can buffer the guide rod 5.

[0046] As a technical optimization of the present invention, a stabilizing groove 26 is provided on the inner wall of the auxiliary cylinder 6, and a stabilizing slider 27 is installed on the side of the extrusion block 25 near the stabilizing groove 26. The stabilizing slider 27 is slidably installed inside the stabilizing groove 26. By sliding the stabilizing slider 27 in the stabilizing groove 26, the sliding stability of the extrusion block 25 in the auxiliary cylinder 6 can be increased.

[0047] As a technical optimization of the present invention, a pressure sensor 30 is installed at the bottom of the inner wall of the auxiliary cylinder 6, and a spring telescopic rod 29 is installed at the bottom of the extrusion block 25, with the bottom of the spring telescopic rod 29 abutting against the top of the pressure sensor 30. The spring telescopic rod 29 not only buffers the guide rod 5, but also enables the pressure sensor 30 to detect the extrusion force on the guide rod 5.

[0048] In use, all electrical devices in this device are powered by an external power source connected via wires. The device controls the electrical devices through a preset control system. The upper mold base 1, lower mold base 2, upper mold body 3, and lower mold body 4 used in this device are all existing mature technologies, and their connection methods are also existing mature technologies, so they will not be described in detail. The top of the upper mold base 1 is connected to the hydraulic rod of the stamping machine, and the bottom of the lower mold base 2 is connected to the bottom of the stamping machine. Their installation methods are existing mature technologies, so they will not be described in detail. When the device is in use, the guide rod 5 can be inserted into the interior of the guide ring 9 and extend into the interior of the auxiliary cylinder 6. A booster pump is provided in the internal cavity of the second connecting rod 14. A sponge can be installed on the outer side of the patch block 22, and a rubber pad is provided on the side of the abutment block 13 away from the first connecting rod 12.

[0049] When the device is in use, the press 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 downward movement of the upper die body 3 can be guided, thereby increasing the stamping accuracy of the upper die body 3 and the lower die body 4.

[0050] When the guide rod 5 moves into the interior of the auxiliary cylinder 6, it will press the compression block 25. After being compressed, the compression block 25 will slide towards the bottom of the auxiliary cylinder 6. During the sliding process, the compression block 25 will press the spring telescopic rod 29. The spring telescopic rod 29 can absorb the force transmitted from the guide rod 5 to the compression block 25, thereby achieving the effect of buffering the guide rod 5, preventing the guide rod 5 from working under large impact for a long time, affecting the normal use of the guide rod 5, and increasing the functional stability of the device.

[0051] During use, or immediately after assembly with the press, the device moves to a preset position by the guide rod 5 striking the extrusion block 25. The pressure sensor 30 measures the extrusion force transmitted by the guide rod 5 and transmits it to the back-end control system. The back-end control system compares the pressure values ​​measured by multiple pressure sensors 30. If multiple pressure values ​​are found to exceed the standard pressure difference range, it indicates that there is a directional deviation in the installation between the upper die holder 1 and the lower die holder 2. At this time, the staff can inspect the device according to the detection results to prevent the device from being damaged by continuous operation under the condition of deviation.

[0052] When it is necessary to detect the offset of the guide rod 5, the rotating block 7 is rotated by the rotary motor 18, so that the laser range sensor 17 rotates to the use position facing the guide rod 5. Then, the rotating block 7 is moved to the preset use position by the sliding of the movable electric slider 11 in the movable slide groove 10. In this case, during the up and down movement of the guide rod 5, multiple laser range sensors 17 measure it and transmit the measurement values ​​to the background control system for comparison. If there is a deviation between multiple values, it indicates that the guide rod 5 is offset when moving up and down. At this time, the staff can repair the device according to the measurement results.

[0053] When the guide rod 5 needs to be lubricated, the rotating block 7 is rotated by the rotary motor 18, 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, and the booster pump preset inside the second connecting rod 14 is started, so that the nozzle 15 can spray oil to the outside of the guide rod 5 for lubrication. In this way, the guide rod 5 can be lubricated during the operation of the device without stopping the machine, which increases the convenience of using the device.

[0054] After the guide rod 5 is lubricated by spraying oil, the pad 22 slides outward by sliding the displacement electric slider 24 in the displacement groove 23. After the pad 22 slides to the preset position, the guide ring 9 rotates inside the guide groove 8 by sliding the movable electric slider 20 in the annular groove 19. This allows the sponge on the outside of the pad 22 to rotate on the outside of the guide rod 5 when the guide rod 5 moves inside the guide ring 9, which can increase the uniformity of the lubricating oil sprayed on the outside of the guide rod 5.

[0055] During transportation, the upper mold base 1 and the lower mold base 2 are aligned with... Figure 1 The docking is performed as shown. First, the rotating block 7 rotates, causing the abutment block 13 to rotate to the side facing the guide rod 5. Then, by moving the electric slider 11 in the sliding groove 10, the rotating block 7 can move towards the guide rod 5 until the abutment block 13 abuts against the outside of the guide rod 5. Through this operation, the guide rod 5 can be fixed in the guide ring 9, thereby fixing the upper mold base 1 and the lower mold base 2, preventing the upper mold body 3 and the lower mold body 4 from shifting during transportation and causing internal damage.

[0056] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
