Description

Technical Field

[0001] This utility model belongs to the field of metal button production technology, and in particular relates to a high-efficiency punching and forming device for five-claw buttons. Background Technology

[0002] Five-prong buckles are commonly used connectors in clothing, bags, and other products. Their structure consists of a ring-shaped metal ring and five claw-shaped protrusions evenly distributed on the inner side. The forming accuracy of the claw teeth and the integrity of the metal ring directly determine the fastening performance. Due to the small size of the five-prong buckle and the need to ensure that each claw tooth is subjected to balanced force, stringent requirements are placed on the punching accuracy, forming stability, and production efficiency of the processing equipment.

[0003] However, traditional punching and forming equipment has many drawbacks. In terms of punching, most equipment uses a single set of cutters to operate in steps, and the opening, forming and separation processes need to be completed in sequence. During the process transition, the positioning reference is prone to shift, resulting in the position deviation between the claw of the five-jaw buckle and the metal ring, and the product qualification rate is low. At the same time, a single processing can only handle a single workpiece, and it is impossible to achieve simultaneous production of multiple pieces. The production efficiency is difficult to meet the needs of mass production. In terms of sheet material fixing, the fixing mechanism of existing equipment is mostly a fixed design, which cannot flexibly adjust the clamping range according to the size of the sheet material, and the clamping stability is insufficient. During the punching process, the sheet material is prone to horizontal slippage due to impact force, which further aggravates the deviation of the punching position.

[0004] To address these issues, we provide a five-claw buckle high-efficiency punching and forming device. Utility Model Content

[0005] The purpose of this utility model is to provide a high-efficiency five-claw buckle punching and forming device. Through the cooperation of the punching mechanism and the fixing mechanism, it solves the problem that the existing five-claw buckle punching and forming device requires the conversion of multiple devices from opening to forming, and the fixing device cannot flexibly adjust the clamping range according to the size of the sheet material.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to a high-efficiency punching and forming device for five-claw buckles, comprising a frame, a mold fixedly connected to the inner cavity of the frame, a punching mechanism fixedly connected to the top of the frame, and a fixing mechanism slidably connected to the bottom of the mold. The punching mechanism includes a cylinder, the bottom of which is fixedly connected to the frame. A push rod is slidably connected to the inner cavity of the cylinder, and the bottom of the push rod passes through the top of the frame and is fixedly connected to a connecting plate. Both sides of the connecting plate are slidably connected to the frame. Five annular cutters are bolted to the bottom of the connecting plate. A pressure block is fixedly connected to the bottom of each annular cutter, and a... The decorative cutter features a through-hole at the top of the mold, which assists in claw buckle forming and allows excess material cut by the decorative cutter to fall directly into the collection box, preventing excess material from accumulating on the mold surface and affecting subsequent processing. Slide rods are fixedly connected to both sides of the mold top, with the top of the slide rods fixedly connected to the frame and the surface of the slide rods slidingly connected to the connecting plate, providing precise guidance for the connecting plate's operation. The connection method between the annular cutter and the connecting plate allows for quick removal and replacement of a damaged annular cutter by simply tightening the corresponding bolt, without requiring extensive disassembly of the entire punching mechanism.

[0008] The present invention is further configured such that the fixing mechanism includes a sliding plate, both sides of which are slidably connected to the mold; a lead screw is rotatably connected to the bottom of the sliding plate via a bearing; a movable frame is threadedly connected to the surface of the lead screw; both sides of the bottom of the movable frame are slidably connected to the sliding plate; and both sides of the top of the movable frame are fixedly connected to a fixing plate. There are two fixing mechanisms, symmetrically distributed on both sides of the top of the mold, which makes the clamping force on the sheet material more balanced and avoids deformation of the sheet material due to uneven force. A knob is provided at the bottom of the movable frame, and the top of the knob is fixedly connected to the lead screw, providing a more convenient point of force application for the operator.

[0009] The present invention is further configured such that guide rods are provided on both sides of the lead screw, the top of the guide rods are fixedly connected to the sliding plate, the surface of the guide rods is slidably connected to the movable frame, and there are two guide rods symmetrically distributed on both sides of the lead screw, which can limit the range of motion of the movable frame.

[0010] The present invention is further provided with an anti-slip pad on the top of the mold, the top of the anti-slip pad being fixedly connected to the fixing plate. The anti-slip pad can increase the friction between the sheet and the fixing plate, and prevent the sheet from shifting during processing.

[0011] The present invention is further provided that a collection box is provided at the bottom of the mold, and both sides of the collection box are slidably connected to the frame. The collection box is used to collect excess material falling from the mold.

[0012] The present invention is further configured such that a sliding groove is provided at the bottom of the inner cavity of the frame, and a slider is slidably connected to the inner cavity of the sliding groove. The other side of the slider is slidably connected to the collection box. The setting of the sliding groove and the slider allows the operator to pull the collection box out from inside the frame for processing of the materials inside.

[0013] The present invention is further configured such that limiting grooves are provided on both sides of the bottom of the mold, and limiting blocks are slidably connected to the inner cavity of the limiting grooves. The bottom of the limiting blocks is fixedly connected to the sliding plate. The setting of the limiting grooves and limiting blocks provides precise guidance and limiting for the sliding plate.

[0014] The present invention is further provided with friction pads on both sides of the limiting block. One side of the friction pad is fixedly connected to the mold. The setting of the friction pad avoids the sliding plate from being displaced due to the shaking of the device. The displacement of the sliding plate will directly cause the fixed plate to shift, thereby affecting the clamping and fixing effect on the sheet material.

[0015] The present invention has the following beneficial effects.

[0016] 1. This utility model punching mechanism, through the combination structure of flower-shaped cutter, pressure block and annular cutter, realizes the integrated and synchronous completion of the hole opening, forming and separation processes. There is no need to change the tool, avoiding the problem of positioning reference offset during process conversion, effectively ensuring the positional accuracy between the claw of the five-claw buckle and the metal ring, and significantly improving the product qualification rate. The annular cutter is set to five, which can punch five five-claw buckles at the same time, realizing the synchronous production of multiple parts. Compared with the traditional method of processing a single workpiece at a time, it greatly increases the output per unit time, speeds up the production rhythm, meets the high efficiency requirements of mass production, and is conducive to expanding the production scale and reducing production costs.

[0017] 2. In the fixing mechanism of this utility model, the sliding plate is slidably connected to the mold and, together with the moving frame driven by the screw, the position of the fixing plate can be flexibly adjusted. It can adjust the clamping range according to the size of the sheet material to meet the processing requirements of different specifications of five-claw buckles. It can also drive the fixing plate to move left and right through the movement of the sliding plate to achieve precise fixing of the sheet material at different positions, effectively avoiding the processing limitations caused by the single fixed position of the sheet material.

[0025] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Example 1

[0027] Please see Figure 1-5 This utility model is a high-efficiency punching and forming device for five-claw buckles, including a frame 1, a mold 2 fixedly connected to the inner cavity of the frame 1, a punching mechanism 3 fixedly connected to the top of the frame 1, a fixing mechanism 4 slidably connected to the bottom of the mold 2, the punching mechanism 3 including a cylinder 301, the bottom of the cylinder 301 fixedly connected to the frame 1, a push rod 302 slidably connected to the inner cavity of the cylinder 301, the bottom of the push rod 302 passes through the top of the frame 1 and is fixedly connected to a connecting plate 303, both sides of the connecting plate 303 are slidably connected to the frame 1, and five annular cutters 304 are bolted to the bottom of the connecting plate 303. A pressure block 305 is fixedly connected to the bottom of the annular cutter 304, and a flower-shaped cutter 306 is fixedly connected to the bottom of the pressure block 305.

[0028] Specifically: The top of the mold 2 has a through hole, which not only assists in the forming of the claw buckle, but also allows the excess material cut by the flower-shaped cutter 306 to fall directly into the collection box 7, avoiding the accumulation of excess material on the surface of the mold 2 and affecting subsequent processing. Both sides of the top of the mold 2 are fixedly connected to slide rods. The top of the slide rods is fixedly connected to the frame 1, and the surface of the slide rods is slidably connected to the connecting plate 303, providing precise guidance for the operation of the connecting plate 303. The connection method between the annular cutter 304 and the connecting plate 303 allows the operator to quickly remove and replace the damaged annular cutter 304 by simply tightening the corresponding bolts when one of the annular cutters 304 is damaged, without having to disassemble the entire punching mechanism 3 on a large scale.

[0029] Example 2

[0030] Please see Figure 1-5 Based on Embodiment 1, the fixing mechanism 4 includes a sliding plate 401, with both sides of the sliding plate 401 slidably connected to the mold 2. A lead screw 402 is rotatably connected to the bottom of the sliding plate 401 via bearings. A movable frame 403 is threadedly connected to the surface of the lead screw 402. Both sides of the bottom of the movable frame 403 are slidably connected to the sliding plate 401. Fixed plates 404 are fixedly connected to both sides of the top of the movable frame 403. Guide rods 5 are provided on both sides of the lead screw 402. The top of the guide rods 5 is fixedly connected to the sliding plate 401, and the surface of the guide rods 5 is slidably connected to the movable frame 403. The top of the mold 2... The mold 2 is equipped with an anti-slip pad 6, the top of which is fixedly connected to the fixing plate 404. The bottom of the mold 2 is equipped with a collection box 7, both sides of which are slidably connected to the frame 1. The bottom of the inner cavity of the frame 1 is provided with a sliding groove 8, and a slider 9 is slidably connected to the inner cavity of the sliding groove 8. The other side of the slider 9 is slidably connected to the collection box 7. Limiting grooves 10 are provided on both sides of the bottom of the mold 2. Limiting blocks 11 are slidably connected to the inner cavity of the limiting grooves 10. The bottom of the limiting blocks 11 is fixedly connected to the sliding plate 401. Friction pads 12 are provided on both sides of the limiting blocks 11, and one side of the friction pads 12 is fixedly connected to the mold 2.

[0031] Specifically: Two fixing mechanisms 4 are symmetrically distributed on both sides of the top of the mold 2, ensuring a more balanced clamping force on the sheet material and preventing deformation due to uneven force. A knob is located at the bottom of the moving frame 403, with its top fixedly connected to the lead screw 402, providing a more convenient point of application for the operator. Two guide rods 5 are symmetrically distributed on both sides of the lead screw 402, limiting the range of motion of the moving frame 403. Anti-slip pads 6 increase the friction between the sheet material and the fixing plate 404, preventing the sheet material from slipping on the ground. During processing, a deviation occurs. The collection box 7 is used to collect excess material falling from the mold 2. The setting of the chute 8 and the slider 9 allows the operator to pull the collection box 7 out of the machine frame 1 for processing of the material inside. The setting of the limiting groove 10 and the limiting block 11 provides precise guidance and limitation for the sliding plate 401. The setting of the friction pad 12 prevents the sliding plate 401 from shifting due to device shaking. The displacement of the sliding plate 401 will directly cause the fixed plate 404 to shift, thus affecting the clamping and fixing effect on the sheet material.

[0032] The working principle of this utility model is as follows: In use, the sheet material is placed on the top of the mold 2, and the fixed position is adjusted by sliding the sliding plate 401. Then, the knob is turned, which drives the lead screw 402 to rotate. The lead screw 402 drives the moving frame 403 to move down along the guide rod 5. The moving frame 403 drives the fixed plate 404 to move down and fix the sheet material. After fixing, the cylinder 301 is started. The cylinder 301 drives the push rod 302, which pushes the connecting plate 303. The connecting plate 303 slides along the sliding rod and presses down. The annular cutter 304 drives the pressure block 305 to move, and the flower-shaped cutter 306 follows the pressure block 305. During the punching process, the flower-shaped cutter 306 first contacts the sheet material and makes a hole in it. Then, the cut sheet material falls into the collection box 7 through the through hole on the mold 2. The flower-shaped cutter 306 enters the through hole, and the pressure block 305 bends the five claws on the sheet material so that they fit against the inner wall of the through hole on the mold 2. Finally, the annular cutter 304 cuts the formed five claw buckle off the sheet material, completing the separation.

The preferred embodiments do not describe all the details in detail, nor do they limit the present utility model to the specific implementation methods described. The present specification selects and specifically describes these embodiments in order to better explain the principle and practical application of the present utility model, so that those skilled in the art can better understand and utilize the present utility model.
