Description
Technical Field
[0001] This utility model relates to the field of hardware processing technology, specifically to a stamping device for zipper production. Background Technology
[0002] Zippers, as a common fastener, are widely used in clothing, bags, outdoor products and other fields. Their quality directly affects the user experience and lifespan of the end product. In the zipper production process, the stamping device is one of the key pieces of equipment, which undertakes the important task of stamping, drilling or positioning the metal or plastic parts of the zipper. Traditional zipper production stamping devices usually include a base, a stamping head and a fixed mold. The stamping head is driven by a hydraulic or mechanical drive mechanism to perform periodic stamping operations on the workpiece. Although this basic structure is simple, its inherent technical limitations are becoming increasingly prominent under the actual large-scale and high-precision production requirements. However, existing zipper stamping devices have many shortcomings, which seriously restrict the further improvement of production efficiency and product quality. The primary problem is that the positioning accuracy of the strip is often poor during the stamping process. As a strip carrier that carries raw materials, the strip needs to achieve precise step positioning at the millimeter or even micrometer level at the stamping station. Traditional equipment often relies on simple mechanical stops or visual calibration, which is a crude positioning method and is easily affected by factors such as equipment vibration, transmission clearance and wear of the mold itself. Every tiny positioning deviation will be accumulated and amplified in the continuous stamping process, resulting in uneven zipper tooth holes, improper zipper head assembly clearance, and even scrapping of the entire strip due to dimensional deviation. This not only directly increases the scrap rate in the production process, but also means that a large amount of raw materials are wasted without being effectively utilized, resulting in the overall utilization rate of the strip always hovering at a low level, which significantly increases the material cost of a single product. Secondly, the handling of materials generated during the stamping process has obvious defects. These materials often fall directly into the equipment or the collection tank below under the stamping pressure. This free-fall handling method seems simple, but it is actually full of hidden dangers. On the one hand, materials of different shapes and masses may collide and splash with each other when falling, making it difficult to collect them in a concentrated manner, resulting in a dirty and messy working environment and posing safety hazards. On the other hand, more seriously, these materials are very easy to accumulate and stick in the corners inside the equipment, on the surface of transmission parts, or in the discharge channel. The accumulation of metal debris may scratch the surface of precision guide rails, accelerate the wear of moving parts, cause the equipment to jam or stop, affect the continuity of production, and also increase the labor intensity of workers and the maintenance cost of equipment. Therefore, there is an urgent need for a new type of stamping device that can maintain ultra-high positioning accuracy under high-speed stamping conditions and achieve automated, orderly, and residue-free material processing, in order to meet the comprehensive requirements of modern manufacturing industry for high efficiency, high quality, low loss, and easy maintenance. Utility Model Content
[0003] The purpose of this invention is to provide a stamping device for zipper production, so as to solve the problems of low utilization rate of material strip and easy accumulation of falling material mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a stamping device for zipper production, comprising a base, a sliding seat mounted on the upper end of the base, a lower pressure plate fixedly mounted on one outer surface of the sliding seat, a forming seat fixedly mounted in the center of the upper surface of the base, a forming punch plate and a positioning punch plate fixedly mounted on the lower surfaces of both ends of the lower pressure plate, a switching motor fixedly mounted on the outer surface of one end of the base, a turntable fixedly connected to the upper end of the output shaft of the switching motor, a positioning seat fixedly mounted on the upper surface of the turntable, and a guide groove fixedly mounted on the upper surface of one end of the base; The middle section of the base has a material discharge port on its outer surface, and a sliding buffer plate is installed on the inner surface of the material discharge port. An electric push rod is fixedly installed inside the lower end of the base, and a support plate is fixedly connected to one end of the electric push rod. A support spring is fixedly installed on the outer surface of the support plate, and an extrusion block is fixedly connected to the lower end of one side of the material discharge port.
[0005] Preferably, the positioning punch plate is disposed on the side of the forming punch plate facing the guide groove, and the lower end of the positioning punch plate is lower than the lower end of the forming punch plate.
[0006] By adopting the above technical solution, the positioning punch plate can contact and engage with the positioning hole of the strip before the forming punch plate, thereby achieving precise positioning before stamping, ensuring the accuracy of forming stamping, and improving the product qualification rate.
[0007] Preferably, the positioning punch plate is located directly above the positioning seat, and the positioning seat is set at an equal angle on the upper surface of the turntable, and the turntable is tilted.
[0008] By adopting the above technical solution, different models of positioning seats can be quickly switched to the working position by switching the motor driving the turntable to adapt to the production needs of different specifications of products, thereby improving the versatility and production efficiency of the equipment.
[0009] Preferably, the buffer plate is inclined, and the outer surface of the buffer plate is in contact with the inner surface of the material discharge port.
[0010] Using the above technical solution, the stamped material can slide smoothly down the inclined buffer plate surface, avoiding direct fall that could cause impact and splashing. At the same time, the fitting design can prevent the material from getting stuck in the gap, thus realizing the orderly collection and diversion of the material.
[0011] Preferably, the support plate is inclined, and the inclination angle of the support plate is the same as that of the buffer plate.
[0012] By adopting the above technical solution, it is ensured that the support plate can provide uniform and stable elastic support to the buffer plate through the support spring, and coordinate with the squeezing block under the drive of the electric push rod to control the sliding and resetting of the buffer plate.
[0013] Preferably, the upper end of the support plate is in contact with the lower end of the compression block, and the upper end of the support spring is in contact with the lower surface of the buffer plate.
[0014] Using the above technical solution, when the electric push rod pulls the support plate to move laterally, the support plate moves downward under the action of the inclined surface of the extrusion block, thereby compressing the support spring and releasing the support of the buffer plate, causing the buffer plate to slide down and increase the discharge port. When resetting, the support spring can lift the buffer plate to restore it to the initial support state, thus realizing the automatic control of the discharge port and the intermittent discharge of materials.
[0015] Compared with the prior art, the beneficial effects of this utility model are: the stamping device for zipper production: 1. By setting a matching structure between the positioning punch plate and the forming punch plate, wherein the lower end of the positioning punch plate is lower than the forming punch plate, the positioning punch plate first contacts the material strip in the cavity after stamping during the stamping process to lock and accurately position it. This ensures that the material strip is accurately positioned when the forming punch plate is stamping, reduces the scrap rate caused by positioning deviation, and significantly improves the utilization rate of the material strip. At the same time, the positioning seats set at equal angles on the turntable are linked with the switching motor to realize rapid switching and accurate positioning of multiple stations, further ensuring the continuity and stability of the stamping process. 2. An orderly material feeding system is formed by setting up a material discharge port, buffer plate, support plate, support spring and electric push rod on the base. The buffer plate is inclined and fits against the inner wall of the material discharge port. The material after stamping slides slowly down the buffer plate, avoiding the impact and accumulation caused by direct drop. The height of the buffer plate can be adjusted by the electric push rod and support spring. In conjunction with the extrusion block, it ensures that the material can be smoothly discharged through the opening between the lowered buffer plate and the material discharge port, preventing blockage. This design reduces material residue inside the equipment, reduces cleaning frequency and maintenance costs, and improves production continuity and equipment service life. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Please see Figures 1-6 This utility model provides a technical solution: a stamping device for zipper production.
[0020] Example 1: This example discloses: a base 1, a sliding slide seat 2 installed on the upper end of the base 1, and a lower pressure plate 3 fixedly installed on one side of the outer surface of the slide seat 2. A forming seat 5 is fixedly installed in the middle of the upper surface of the base 1. A forming punch plate 4 and a positioning punch plate 6 are fixedly installed on the lower surfaces of both ends of the lower pressure plate 3. A switching motor 7 is fixedly installed on the outer surface of one end of the base 1. A turntable 8 is fixedly connected to the upper end of the output shaft of the switching motor 7. A positioning seat 9 is fixedly installed on the upper surface of the turntable 8. A guide groove 10 is fixedly installed on the upper surface of one end of the base 1. The positioning punch plate 6 is located on the side of the forming punch plate 4 facing the guide groove 10, and the lower end of the positioning punch plate 6 is lower than the lower end of the forming punch plate 4. The positioning punch plate 6 is located directly above the positioning seat 9, and the positioning seat 9 is set at equal angles on the upper surface of the turntable 8, and the turntable 8 is set at an angle. When the strip is fed into the stamping area, the sliding seat 2 at the upper end of the base 1 is driven by the hydraulic equipment to lower the pressure plate 3. Since the lower end of the positioning punch plate 6 is lower than the forming punch plate 4, it will contact the strip first. The positioning punch plate 6 is inserted into the positioning hole or cavity pre-stamped on the strip to lock in place, achieving precise positioning and ensuring the accuracy of subsequent stamping. After positioning is completed, the lower pressure plate 3 continues to descend, and the forming punch plate 4 stamps the fixed strip on the forming seat 5. The strip is stably guided and moved under the action of the guide groove 10. After stamping is completed, the zipper model design needs to be changed. First, the forming punch plate 4, forming seat 5 and positioning punch plate 6 are replaced. Then, the motor 7 drives the turntable 8 to rotate at a certain angle to change the model of the positioning seat 9 so that the positioning seat 9 can adapt to the shape of the replaced positioning punch plate 6.
[0021] Example 2: This example is based on Example 1: A material discharge port 11 is provided on the outer surface of the middle section of the base 1, and a sliding buffer plate 12 is installed on the inner surface of the material discharge port 11. An electric push rod 13 is fixedly installed inside the lower end of the base 1, and a support plate 14 is fixedly connected to one end of the electric push rod 13. A support spring 15 is fixedly provided on the outer surface of the support plate 14, and an extrusion block 16 is fixedly connected to the lower end of one side of the material discharge port 11. The buffer plate 12 is inclined, and the outer surface of the buffer plate 12 is in contact with the inner surface of the discharge port 11. The support plate 14 is inclined, and the inclination angle of the support plate 14 is the same as that of the buffer plate 12. The upper end of the support plate 14 is in contact with the lower end of the extrusion block 16, and the upper end of the support spring 15 is in contact with the lower surface of the buffer plate 12. The material generated during the stamping process falls downward into the discharge port 11. The inclined buffer plate 12 is attached to the inner wall of the discharge port 11. After the material falls, it first falls onto the buffer plate 12. The buffer plate 12 buffers the material under the support of the support spring 15. The material slowly slides down the inclined surface of the buffer plate 12 to the bottom and gathers. When material needs to be discharged, the electric push rod 13 is activated, pulling the support plate 14 to move laterally. The support plate 14 drives the support spring 15 to move and releases its support on the buffer plate 12 under the pressure of the extrusion block 16, allowing the buffer plate 12 to slide down naturally and increasing the gap between it and the inner wall of the discharge port 11. At the same time, the material gathered at the bottom of the buffer plate 12 is discharged from the equipment in an orderly manner through the increased gap under the action of gravity.
[0022] After the material is discharged, the electric push rod 13 unfolds, and the buffer plate 12 moves upward to return to its original position under the action of the support spring 15, ready for the next material collection.
[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
