Description

Technical Field

[0001] This utility model relates to the field of hardware stamping die technology, and in particular to a wear-resistant hardware stamping die. Background Technology

[0002] Metal stamping dies are an important tool in metal processing. They work together with upper and lower dies to apply pressure to metal materials, thereby achieving plastic deformation or separation of the materials and producing the required parts.

[0003] Traditional metal stamping dies are usually installed and fixed by bolts. When the die needs to be replaced, multiple bolts need to be removed and installed, which is cumbersome and reduces equipment utilization. At the same time, the cooling system used during stamping often relies on external oil pumps, which have complex pipelines and are difficult to recover oil, resulting in lubricant waste. Therefore, we propose a wear-resistant metal stamping die to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to solve the shortcomings of existing hardware stamping dies, such as the cumbersome replacement and disassembly caused by bolt installation, the reliance on external oil pumps for cooling systems, the complex pipelines, the difficulty in oil recovery, and the waste of lubricant. Therefore, a wear-resistant hardware stamping die is proposed.

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

[0006] A wear-resistant metal stamping die includes a lower die base. Guide pillars are fixedly connected to the four corners of the top of the lower die base. An upper die base is slidably mounted on the four guide pillars. A lower die is slidably connected to the top of the lower die base. An upper die is slidably connected to the bottom of the upper die base. Two wedge-shaped blocks are symmetrically fixedly mounted on the top of the lower die base and the bottom of the upper die base. Wedge-shaped grooves corresponding to the wedge-shaped blocks are opened on the bottom of the lower die and the top of the upper die. The wedge-shaped grooves of the lower die are slidably connected to the wedge-shaped blocks of the lower die base, and the wedge-shaped grooves of the upper die are slidably connected to the wedge-shaped blocks of the upper die base.

[0007] The top of the lower mold base and the bottom of the upper mold base are both provided with limiting components. The limiting components include a limiting block that is slidably disposed in the sliding groove at the top of the lower mold base and a limiting groove opened at the bottom of the lower mold base. The top of the limiting block extends to the top of the lower mold base and is inserted into the limiting groove.

[0008] During mold installation, the wedge-shaped groove and the wedge-shaped locking block slide together to achieve rapid mold positioning, and the limiting block and the limiting groove cooperate to achieve horizontal fixation.

[0009] In one possible design, a fixing block is fixedly installed at the top of the lower mold base and the bottom of the upper mold base. A groove is opened on one side of both the lower mold and the upper mold. The fixing block is embedded in the groove and cooperates with the limiting component to limit the horizontal position.

[0010] In one possible design, the limiting assembly further includes a limiting rod fixedly disposed at the bottom of the slide groove. The top end of the limiting rod is slidably inserted into the interior of the limiting block. A spring is sleeved on the limiting rod, and the two ends of the spring abut against the inner wall of the bottom of the slide groove and the bottom of the limiting block, respectively. A toggle block is fixedly connected to one side of the limiting block, and the toggle block extends to the outside of the lower mold base. The toggle block can be manually moved to disengage the limiting block from the limiting groove, thereby achieving quick disassembly.

[0011] In one possible design, an oil tank is fixedly connected to the bottom of the lower mold base, and an oil spraying assembly is provided on the oil tank. The oil spraying assembly includes an oil cylinder fixedly installed inside the oil tank and two oil guide pipes connected to the oil cylinder. Each of the two oil guide pipes is fixedly connected to a nozzle, and the nozzles face the lower mold.

[0012] In one possible design, the oil injection assembly further includes a push rod, the bottom end of which slides into the interior of the oil cylinder and is fixedly connected to a piston. The piston is slidably and sealingly connected to the inner wall of the oil cylinder. A connecting block is fixedly connected to one side of the upper mold base. The push rod slides through the connecting block, and a limit nut is threaded onto the push rod.

[0013] In one possible design, a filter cylinder is fixedly installed at the bottom oil inlet of the oil cylinder, and a one-way valve is fixedly installed at the bottom liquid inlet of the oil cylinder and on the oil guide pipe; wherein, the upper mold base moves downward to push the push rod to drive the piston to squeeze the oil out of the nozzle to achieve automatic lubrication.

[0014] In one possible design, both the lower mold base and the oil tank are provided with discharge ports, and the upper mold base is provided with clearance holes.

[0015] In one possible design, the lower mold and the upper mold have the same structure, with a concave mold at the top of the lower mold and a convex mold at the bottom of the upper mold.

[0016] In this application, firstly, guide pillars are fixedly connected to the four corners of the top of the lower mold base, and the upper mold base is slidably set on the four guide pillars. When installing the mold, taking the lower mold as an example, the push block is pressed down, the limit block is squeezed, moves down along the limit rod and compresses the spring. Then, the wedge groove at the bottom of the lower mold is inserted along the wedge-shaped block of the lower mold base. The wedge-shaped surfaces of the two wedge-shaped blocks limit the vertical position of the lower mold. When the limit groove moves to the position of the limit block, the spring pushes the limit block to move up and lock into the limit groove. At the same time, the fixing block is embedded in the groove to achieve horizontal locking. The upper mold is installed in the same way. When it is necessary to replace the mold, the push block is pressed down, so that the limit block retracts into the slide groove, releasing the limitation on the horizontal position of the lower mold. Then the lower mold can be pulled out along the wedge-shaped block to complete the quick disassembly of the mold.

[0017] During stamping, the upper die holder moves downward along the guide post under the drive of the press, causing the upper and lower dies to cooperate in stamping the material. During this process, the upper die holder pushes the push rod downward, causing the piston to slide downward in the oil cylinder. At this time, the space inside the oil cylinder shrinks, and the stamping oil is squeezed and the pressure increases. The one-way valve at the oil cylinder inlet closes to prevent the stamping oil from flowing back into the oil tank, while the one-way valves on the two oil guide pipes are pushed open. The pressurized stamping oil is sprayed out from the nozzle along the oil guide pipe and sprayed onto the surface of the lower die. The die holder rises and drives the push rod upward. The oil in the oil tank is drawn into the oil cylinder through the filter cartridge. This process is repeated to achieve automatic lubrication and cooling of the die by the lubricant. Excess lubricant sprayed on the surface of the lower die will flow back into the oil tank.

[0018] Beneficial effects: In this utility model, the wear-resistant metal stamping die uses wedge-shaped blocks set at the top of the lower die base and the bottom of the upper die base to slide in conjunction with the wedge-shaped grooves corresponding to the lower and upper dies. When installing the die, simply align the wedge-shaped grooves on the die with the wedge-shaped blocks and push it in along the guide direction to quickly complete the initial positioning and installation of the die. Compared with the traditional bolt fastening method, there is no need to use tools to tighten multiple bolts, which greatly shortens the die installation time, reduces the installation difficulty, and improves the efficiency of pre-production preparation.

[0019] In this utility model, the wear-resistant metal stamping die uses a limiting block and a limiting groove in the limiting component to limit and fix the die in the horizontal direction. When the die needs to be disassembled for maintenance, the operator only needs to manually move the moving block to overcome the spring force and make the limiting block disengage from the limiting groove, thereby releasing the horizontal fixation of the die and allowing it to slide out of the die. No complicated tools or complicated operating steps are required, which greatly improves the efficiency of die disassembly and reduces maintenance time and costs.

[0020] In this utility model, the wear-resistant metal stamping die is described. When the upper die base moves downward, the connecting block pushes the push rod, which drives the piston to squeeze the oil in the oil cylinder. The oil is then sprayed from the nozzle onto the die surface through the oil guide pipe. When the upper die rises, the spring resets the piston, and the oil in the oil tank is drawn into the oil cylinder through the filter. No external power is required throughout the process, which realizes automatic lubrication and cooling of the die by the lubricant, thus extending the service life of the die.

[0021] In this invention, the sliding cooperation between the wedge-shaped block and the wedge-shaped groove enables the mold to be quickly and initially positioned and installed, which significantly shortens the installation time and reduces the difficulty compared to traditional bolt fastening. The limiting block and the limiting groove in the limiting component allow the mold to be released by manual movement, which is convenient for disassembly and maintenance. The movement of the upper mold base drives the oil spraying component, which does not require external power and enables the lubricant to automatically lubricate and cool the mold, effectively extending the service life of the mold.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] In one embodiment: Refer to Figure 1-5 A mold includes a lower mold base 1, with guide pillars 2 fixedly connected to the four corners of the top of the lower mold base 1, and an upper mold base 3 slidably mounted on the four guide pillars 2. A lower mold 4 is slidably connected to the top of the lower mold base 1, and an upper mold 5 is slidably connected to the bottom of the upper mold base 3. The lower mold 4 and the upper mold 5 have the same structure. A cavity is provided at the top of the lower mold 4, and a punch is provided at the bottom of the upper mold 5.

[0030] Two wedge-shaped locking blocks 6 are symmetrically fixedly installed on the top of the lower mold base 1 and the bottom of the upper mold base 3. Wedge-shaped grooves 7 corresponding to the wedge-shaped locking blocks 6 are opened on the bottom of the lower mold 4 and the top of the upper mold 5. The two wedge-shaped grooves 7 on the lower mold 4 are slidably connected to the two wedge-shaped locking blocks 6 on the lower mold base 1, and the two wedge-shaped grooves 7 on the upper mold 5 are slidably connected to the two wedge-shaped locking blocks 6 on the upper mold base 3. Through the sliding engagement of the wedge-shaped locking blocks 6 on the top of the lower mold base 1 and the bottom of the upper mold base 3 with the corresponding wedge-shaped grooves 7 on the lower mold 4 and the upper mold 5, during mold installation, simply align the wedge-shaped grooves 7 on the mold with the wedge-shaped locking blocks 6 and push it in along the guide direction to quickly complete the initial positioning and installation of the mold.

[0031] Limiting components are provided at the top of the lower mold base 1 and the bottom of the upper mold base 3 to limit the position of the lower mold 4 or the upper mold 5. The limiting components include a limiting block 8 slidably disposed within a groove opened at the top of the lower mold base 1, and a limiting groove opened at the bottom of the lower mold 4 that matches the limiting block 8. The limiting components also include a limiting rod 9 fixedly disposed inside the bottom of the groove. The top end of the limiting rod 9 slidably inserts into the interior of the limiting block 8, and a spring 10 is sleeved on the limiting rod 9. Both ends of the spring 10 abut against the bottom inner wall of the groove and the bottom of the limiting block 8, respectively. A movable actuating block is fixedly connected to one side of the limiting block 8, and one end of the actuating block passes through an opening in the lower mold base 1 and extends to the outside of the lower mold base 1.

[0032] When installing the mold, taking mold 4 as an example, pressing down the actuating block compresses the limiting block 8, causing it to move downwards along the limiting rod 9 and compress the spring 10. Then, the wedge-shaped groove 7 at the bottom of the lower mold 4 is inserted along the wedge-shaped locking block 6 of the lower mold base 1. When the limiting groove moves to the position of the limiting block 8, the spring 10 pushes the limiting block 8 upwards and locks it into the limiting groove. At the same time, the fixing block 20 is embedded in the groove 21, achieving horizontal locking. Compared with the traditional bolt fastening method, it eliminates the need to use tools to tighten multiple bolts, greatly shortening the mold installation time, reducing installation difficulty, and improving the efficiency of pre-production preparation.

[0033] When it is necessary to replace the mold, press down and move the toggle block to retract the limit block 8 into the slide groove, release the restriction on the horizontal position of the lower mold 4, and then the lower mold 4 can be pulled out along the wedge-shaped locking block 6 to complete the quick disassembly of the mold, greatly improve the mold disassembly efficiency, and reduce maintenance time and cost.

[0034] Fixing blocks 20 are fixedly installed on the top of the lower mold base 1 and the bottom of the upper mold base 3. Grooves 21 are opened on one side of the lower mold 4 and the upper mold 5. The two fixing blocks 20 are embedded in the corresponding grooves 21 and cooperate with the corresponding limiting components to limit the horizontal position of the lower mold 4 or the upper mold 5.

[0035] This application can be used in the field of metal stamping die technology, or in other fields applicable to this application.

[0036] In another embodiment: Reference Figure 3-5 Based on Embodiment 1, an improvement is made: a wear-resistant metal stamping die, applied in the field of metal stamping die technology. An oil tank 22 is fixedly connected to the bottom of the lower die base 1, and the lower die base 1 is embedded inside the oil tank 22. An oil spraying assembly is provided on the oil tank 22 for cooling and lubrication. The oil spraying assembly includes an oil cylinder 11 fixedly installed inside the oil tank 22 and two oil guide pipes 12 connected to the oil cylinder 11. Each of the two oil guide pipes 12 is fixedly connected to a nozzle 13, and the two nozzles 13 face the lower die 4. The oil spraying assembly also includes a push rod 14, the bottom end of which slides into the interior of the oil cylinder 11 and is fixedly connected to a piston 15. The outer wall of the piston 15 is slidably connected to the inner wall of the oil cylinder 11. A connecting block 17 is fixedly connected to one side of the upper die base 3. The push rod 14 slides through the connecting block 17, and limiting nuts 18 for limiting are threaded onto the push rod 14 above and below the connecting block 17. A filter cylinder 19 is fixedly installed at the bottom oil inlet of the oil cylinder 11, and a one-way valve 16 is fixedly installed at the bottom liquid inlet of the oil cylinder 11 and on the two oil guide pipes 12.

[0037] During stamping, the upper die holder 3 moves downward along the guide post 2 under the drive of the press, causing the upper die 5 and the lower die 4 to cooperate in stamping the material. During this process, the upper die holder 3 pushes the push rod 14 downward, causing the piston 15 to slide downward in the oil cylinder 11. At this time, the space inside the oil cylinder 11 shrinks, and the stamping oil is squeezed and the pressure increases. The one-way valve 16 at the oil inlet of the oil cylinder 11 closes to prevent the stamping oil from flowing back to the oil tank 22, while the one-way valves 16 on the two oil guide pipes 12 are pushed open. The pressurized stamping oil is sprayed out from the nozzle 13 along the oil guide pipes 12 and sprayed onto the surface of the lower die 4. The upper die holder 3 rises, causing the push rod 14 to move upward. The oil in the oil tank 22 is drawn into the oil cylinder 11 through the filter cartridge 19. This process is repeated to achieve automatic lubrication and cooling of the die by the lubricant. No external power is required throughout the process, which extends the service life of the die. Excess lubricant sprayed on the surface of the lower die 4 will flow back into the oil tank 22.

[0038] Both the lower die holder 1 and the oil tank 22 are provided with discharge ports 101 to facilitate material unloading, and the upper die holder 3 is provided with multiple clearance holes 301 for clearance, so as to ensure the smooth operation of the stamping work.

[0039] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
