Description

A stamping die and a quick disassembly structure Technical Field

[0001] This utility model belongs to the field of stamping die technology, and specifically relates to a stamping die and a quick disassembly structure. Background Technology

[0002] Stamping dies are core tools used for forming and processing sheet metal. They are typically mounted on a press (such as a punch press) and apply instantaneous high pressure to shear, bend, stretch, or shape the material, thereby mass-producing parts with uniform shapes. Guide pillars and guide sleeves are key guiding components in stamping dies, ensuring precise alignment of the upper and lower dies during the closing process. Working together, they control the vertical movement trajectory of the die, preventing misalignment, jamming, or dimensional deviations in parts caused by uneven loading. Guide pillars are usually cylindrical steel rods fixed to the lower die base, while guide sleeves are installed inside the upper die base, with inner walls containing lubricating oil grooves or self-lubricating materials (such as graphite copper sleeves). Traditionally, guide pillars and guide sleeves are fixed using interference fits or bolts, requiring disassembly of the entire die structure (such as templates and backing plates) for replacement, which can take several hours. Therefore, a new structure is proposed to solve these problems. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a stamping die and a quick disassembly structure to solve the problems mentioned in the background art.

[0005] An upper mold base is provided above the lower mold base. Four mounting slots are provided at the four corners of the bottom of the upper mold base. A guide sleeve is installed inside each mounting slot. A fitting ring is provided at the bottom of the guide sleeve. A quick-release slot is provided at the front and rear positions of the inner side of the fitting ring.

[0006] In a preferred embodiment, a fixing post is provided at each of the four corners of the top of the lower mold base. The top of the fixing post is recessed downward to form a docking groove. A base plate is provided at the bottom of the fixing post, and a buffer ring is provided at the top of the base plate.

[0007] In a preferred embodiment, the radius and depth of the inner side of the mating groove match the radius and height of the mating screw, the outer side of the mating screw is provided with a thread, and the inner side of the mating groove is provided with an internal thread groove that matches the specification of the thread.

[0008] In a preferred embodiment, a gasket is fitted on the outer side of the upper part of the docking screw, and a buffer pad is provided on the top of the guide post body, the radius of the buffer pad being matched with the radius of the guide post body.

[0009] In a preferred embodiment, a fitting groove is provided on the outer side below the mounting groove, the radius of the fitting groove is greater than the radius of the mounting groove, and a sealing ring for sealing is provided on the inner side of the fitting groove.

[0010] In a preferred embodiment, the radius and depth of the mounting groove match the radius and depth of the outer side of the guide sleeve. An inner thread groove is provided on the inner side of the mounting groove, and a thread matching the specifications of the inner thread groove is provided on the outer side of the guide sleeve.

[0011] In a preferred embodiment, the inner radius of the guide sleeve is the same as the inner radius of the fitting ring, the inner radius of the guide sleeve matches the radius of the guide post body, and the total length of the guide post assembly and the fixing post matches the depth of the guide sleeve.

[0012] In a preferred embodiment, a second buffer pad is provided on the inner upper surface of the guide sleeve. The specifications of the second buffer pad match those of the first buffer pad, and both the second buffer pad and the first buffer pad are made of flexible rubber.

[0013] After adopting the above technical solution, the beneficial effects of this utility model are as follows: 1. By setting guide post assemblies and guide sleeves, the guide post assembly includes a guide post body and a docking screw. The guide post body is threadedly connected and fixed to the docking groove at the top of the fixed post through the docking screw. Then, four sets of guide post assemblies are installed on the top of four sets of fixed posts at the four corners of the lower mold base. An upper mold base is provided above the lower mold base. An installation groove is opened at the four corners of the bottom of the upper mold base. An interlocking groove is opened on the outer side below the installation groove. Four sets of guide sleeves are threadedly connected to the inside of the installation groove, and the interlocking ring at the bottom of the guide sleeve is interlocked and installed inside the interlocking groove. When it is necessary to disassemble the guide post assembly and guide sleeves, the guide post body can be rotated first to drive the docking screw to disengage from the inside of the docking groove, so that the guide post assembly can be quickly removed. Then, a flathead screwdriver can be inserted into the quick-release slots at the front and rear positions of the inner side of the interlocking ring, and the interlocking ring can be rotated in the opposite direction to drive the guide sleeve to disengage from the inside of the installation groove, so that the guide sleeve can be quickly removed. Therefore, the final effect is to significantly improve the disassembly efficiency of the guide post assembly and guide sleeves.

[0014] 2. By setting buffer pad one, buffer pad two, buffer ring, and sealing ring, buffer pad one is set on the top of the guide post body, and buffer pad two is located on the upper inner surface of the guide sleeve. When the guide post assembly and the guide sleeve are in contact and guiding, the guide post body is located inside the guide sleeve. When the upper mold base moves downward and approaches the lower mold base, the contact and compression between buffer pad one and buffer pad two buffer the impact force. At the same time, the bottom of the fitting ring and the top of the buffer ring on the top of the base plate are pressed against each other. The buffer ring can also weaken the impact force through its buffering effect. At the same time, the contact between the top of the buffer ring and the bottom of the fitting ring can also achieve a sealing effect. After the guide sleeve is installed inside the mounting groove, the top of the fitting ring and the sealing ring inside the fitting groove are pressed tightly together, thereby achieving a sealing effect through the sealing ring and preventing lubricating oil from overflowing.

[0035] Example 1: Please refer to Figures 1 to 5. In actual use, the lower die holder 100 is installed on the worktable. An upper die holder 200 is provided above the lower die holder 100. The top of the upper die holder 200 is connected to the punch press. The punch press provides pressure to close the upper die holder 200 and the lower die holder 100. A fixing post 110 is provided at each of the four corners of the top of the lower die holder 100. The fixing post 110 is fixed to the top of the lower die holder 100 by a base plate. The top of the fixing post 110 is recessed downward to form a mating groove 111 for fixing. A guide post assembly 300 is installed inside the column 110. The guide post assembly 300 includes a guide post body 310 and a connecting screw 311. The connecting screw 311 is located below the guide post body 310 and is an integral structure with the guide post body 310. The connecting screw 311 is threadedly connected to the connecting groove 111, thereby installing the guide post body 310 on the top of the fixed column 110. After the connecting screw 311 is screwed into the connecting groove 111, the top of the fixed column 110 is pressed tightly against the gasket on the outer side above the connecting screw 311. The guide post assembly 300 is tightly installed. An installation groove 210 is provided at each of the four corners of the bottom of the upper mold base 200. A fitting groove 211 is provided on the outer side below the installation groove 210. The radius of the fitting groove 211 is greater than the radius of the bottom of the installation groove 210. A guide sleeve 400 is threadedly installed inside the installation groove 210. A fitting ring 410 is provided at the bottom of the guide sleeve 400. A quick-release slot 411 is provided at the front and rear positions of the inner side of the fitting ring 410. A pair of quick-release slots 411... 1. The quick-release slots 411 are symmetrically arranged, and the distance between them is matched with the width of the external flathead screwdriver. The width of the inner side of the quick-release slot 411 is matched with the thickness of the flathead screwdriver. After the guide sleeve 400 and the mounting groove 210 are installed, the fitting ring 410 is located inside the fitting groove 211 and its bottom is flush with the bottom of the upper mold base 200. It should be noted that an oil leakage hole is provided on the back of the curved side of the guide sleeve 400, so that lubricating oil can enter the inner side of the guide sleeve 400 through the oil leakage hole.

[0036] In actual use, the upper die holder 200 moves downward and approaches the lower die holder 100 under the drive of the punch press. At this time, the four sets of guide post assemblies 300 move upward along the inner sides of the four sets of guide sleeves 400, thereby providing precise guidance to the upper die holder 200 and the lower die holder 100 through the cooperation of the guide post assemblies 300 and the guide sleeves 400 (the working process of the upper die holder 200 and the lower die holder 100 is existing technology, and its internal structure and working principle will not be described in detail here). When it is necessary to disassemble the guide post assembly 300 and the guide sleeve 400 assembly, a tool such as a wrench can be used to pinch the outer side of the guide post body 310. A layer of rubber can be glued to the inside of the wrench to protect it. While protecting the guide post body 310 from scratches, it also increases the friction between the guide post body 310 and the guide post body 310. By rotating the guide post body 310 in the opposite direction, the guide post body 310 drives the docking screw 311 to disengage from the docking groove 111, thereby allowing the guide post assembly 300 to be quickly removed. Then, a flathead screwdriver can be used. With the tip of the flathead screwdriver in a vertical position, it is inserted into the two sets of quick-release slots 411. By rotating the engagement ring 410 in the opposite direction, the guide sleeve 400 is rotated out of the mounting groove 210, and the guide sleeve 400 can be removed. Therefore, the final effect is to significantly improve the disassembly efficiency of the guide post body 310 and the guide sleeve 400, thereby facilitating maintenance.

[0037] Example 2: Please refer to Figures 2 to 5. A buffer pad 312 is provided on the top of the guide post body 310, and a buffer pad 401 is provided on the upper inner surface of the guide sleeve 400. Buffer pad 312 and buffer pad 401 have the same specifications. A buffer ring 112 is provided on the top of the base plate. The inner side of the buffer ring 112 contacts the outer side of the fixed post 110, and the radius of the buffer ring 112 matches the radius of the fitting ring 410. A sealing ring 220 is installed inside the fitting groove 211 below the fitting ring 410. After the guide sleeve 400 and the mounting groove 210 are installed, the sealing ring 220 is tightly pressed into the fitting groove 211 by the fitting ring 410, thereby protecting the mounting groove 210 and the guide sleeve 400. The guide post assembly 300 and the guide sleeve 400 work together to guide the lubricant. At this time, the guide post body 310 is inside the guide sleeve 400. When the upper mold base 200 moves downward and approaches the lower mold base 100, the guide post body 310 moves upward along the inner side of the guide sleeve 400. The top of the buffer pad 1 312 contacts and presses against the bottom of the buffer pad 2 401. The friction between the rubber molecules can buffer the upper mold base 200 and the lower mold base 100. At the same time, the top of the buffer ring 112 presses against the bottom of the fitting ring 410, thus providing both a buffering effect and a sealing effect to prevent the lubricant from overflowing.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
