Abstract
Description
Technical Field
[0001] This utility model relates to the field of stamping equipment technology, and in particular to a replaceable stamping head for metal stamping. Background Technology
[0002] By utilizing the immense pressure generated by stamping equipment, the force is concentrated onto sheet metal or blanks through replaceable punch heads. This causes the material to undergo plastic deformation or fracture under the action of the punch, thereby achieving stamping processes such as cutting, punching, and forming. The replaceable punch head design means that for different stamping tasks, only the appropriate punch needs to be replaced, without requiring large-scale adjustments to the entire stamping equipment.
[0003] In the prior art, to speed up the replacement rate of the stamping head, the bolt connection structure is usually eliminated and a pin connection is used. However, in actual operation, the overall process of replacing the pin structure is still relatively cumbersome and there is still much room for improvement. Therefore, a new structure is needed to solve the above problems. Utility Model Content
[0004] The purpose of this utility model is to provide a replaceable stamping head for metal stamping, in order to solve the problem mentioned in the background art, that in order to speed up the replacement rate of the stamping head, the bolt connection structure is usually eliminated and a pin connection is used. However, in actual operation, the overall steps of the pin replacement structure are still relatively cumbersome and there is still a lot of room for improvement.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0006] This utility model relates to a replaceable stamping head for metal stamping, comprising:
[0007] A stamping arm and a stamping head, wherein the stamping head is movably connected to the bottom of the stamping arm;
[0008] The easily replaceable components include slots, insert rods, receiving grooves, moving rods, annular grooves, mounting grooves, springs, locking blocks, and locking slots. A slot is formed at the bottom of the stamping arm. An insert rod is fixedly connected to the top of the stamping head, and the insert rod is movably connected to the slot. Receiving grooves are formed at both ends of the bottom of the stamping arm. Moving rods are fixedly connected to both sides of the insert rod, and the moving rods are movably connected to the receiving grooves. An annular groove is formed on the stamping arm, and a moving rod is movably connected within the annular groove. A mounting groove is formed on the side of the moving rod, and one end of a spring is fixedly connected to the inside of the mounting groove. A locking block is fixedly connected to the other end of the spring. Locking slots are formed through both ends of the stamping arm, and locking blocks are movably connected within the locking slots.
[0009] Furthermore, the side of the movable rod is arc-shaped.
[0010] Furthermore, the annular groove connects the slot and the receiving groove.
[0011] Furthermore, the annular groove connects to the card slot.
[0012] Furthermore, the card block is composed of a cylindrical rod and a hemisphere.
[0013] Furthermore, it also includes an auxiliary assembly / disassembly component, which includes a strip-shaped limiting groove and a movable limiting block. The upper and lower ends of the mounting groove in the movable rod are provided with strip-shaped limiting grooves. The upper and lower ends of the cylindrical rod of the locking block are fixedly connected to the movable limiting block, and the movable limiting block is movably connected in the strip-shaped limiting groove.
[0014] Compared with existing technologies, the advantages of this utility model are:
[0015] In this invention, during disassembly, simply press the two end blocks, then rotate the punch head 90 degrees, and then pull it downwards to remove the punch head connecting rod from the punch arm. During installation, simply insert the top rod of the new punch head into the slot, and then rotate it 90 degrees again to install the new punch head. The above disassembly and replacement process is simpler and faster than the pin replacement structure.
[0016] Based on the aforementioned beneficial effects, the movement range of the card block can be limited by the cooperation of the moving limit block and the strip-shaped limit groove. That is, the card block can only move within the moving rod, preventing the card block from disengaging from the moving rod. This ensures that the card block can be quickly inserted and slid out of the slot, guaranteeing a high rate of stamping head replacement. Attached Figure Description

[0031] Please see Figure 1-6 As shown, this embodiment is a replaceable stamping head for metal stamping, comprising:
[0032] The stamping arm 101 and the stamping head 102 are movably connected to the bottom of the stamping arm 101;
[0033] The easily replaceable components include a slot 201, a rod 202, a receiving groove 203, a moving rod 204, an annular groove 205, a mounting groove 206, a spring 207, a locking block 208, and a locking slot 209. The slot 201 is located at the bottom of the stamping arm 101. The rod 202 is fixedly connected to the top of the stamping head 102, and the rod 202 is movably connected to the slot 201. Receiving grooves 203 are located at both ends of the bottom of the stamping arm 101, and the rod 202 is fixed on both sides. A fixed connecting rod 204 is movably connected to a receiving groove 203. An annular groove 205 is opened on the stamping arm 101, in which the moving rod 204 is movably connected. An installation groove 206 is opened on the side of the moving rod 204. One end of a spring 207 is fixedly connected to the inner side of the installation groove 206, and the other end of the spring 207 is fixedly connected to a locking block 208. A locking groove 209 is opened through both ends of the stamping arm 101, in which the locking block 208 is movably connected.
[0034] The slot 201 and the insertion rod 202 work together to ensure the initial connection of the stamping head 102 to the stamping arm 101. The receiving groove 203 ensures the insertion of the moving rod 204. The annular groove 205 provides space for the rotation of the moving rod 204. The mounting groove 206 provides space for the connection of the spring 207 and the locking block 208. The spring 207 ensures the movable connection of the locking block 208 to the locking groove 209.
[0035] The side of the movable rod 204 is arc-shaped;
[0036] The shape of the movable rod 204 is designed so that its outer trajectory is circular when it rotates, thus better conforming to the shape of the annular groove 205 and ensuring the smooth rotation of the movable rod 204 itself.
[0037] The annular groove 205 connects to the slot 201 and the receiving groove 203, and the annular groove 205 connects to the card slot 209;
[0038] The positional relationship between the above components ensures that the moving rod 204 can smoothly enter the annular groove 205, and that the locking block 208 can smoothly enter the locking slot 209.
[0039] Block 208 is composed of a cylindrical rod and a hemisphere.
[0040] The hemispherical structure on the side of the card block 208 ensures that the card block 208 can be quickly inserted and removed from the card slot 209.
[0041] It also includes auxiliary disassembly and assembly components, which include a strip-shaped limiting groove 301 and a movable limiting block 302. The upper and lower ends of the mounting groove 206 in the movable rod 204 are provided with strip-shaped limiting grooves 301. The upper and lower ends of the cylindrical rod of the locking block 208 are fixedly connected to the movable limiting block 302, and the movable limiting block 302 is movably connected in the strip-shaped limiting groove 301.
[0042] The strip-shaped limiting groove 301 and the moving limiting block 302 work together to ensure that the movement range of the card block 208 is limited.
[0043] Working principle: First, insert the top rod 202 of the stamping head 102 into the slot 201 at the bottom of the stamping arm 101. When the locking block 208 contacts the stamping arm 101, press down the locking blocks 208 at both ends. At this time, the locking blocks 208 move into the mounting groove 206, and the spring 207 is compressed in the mounting groove 206. Then, continue to move the stamping head 102 upward until the moving rod 204 is fully pushed into the receiving groove 203. When the rod 202 moves to the top of the slot 201, rotate the stamping head 102. At this time, the moving rod 204 rotates in the annular groove 205 until... When the locking block 208 in the moving rod 204 moves to the position of the slot 209, the spring 207 returns to its original state, pushing the locking block 208 into the slot 209 to install the punch head 102. When it is necessary to disassemble and replace the punch head 102, simply press the locking blocks 208 at both ends. After the locking blocks 208 disengage from the slot 209, rotate the punch head 102 accordingly. When the moving rod 204 rotates to the position of the receiving groove 203, pull the punch head 102 down to disassemble the punch head 102 and the insert rod 202. This step is simpler and faster than the pin replacement structure.
