Description

Technical Field

[0001] This utility model relates to the field of precision punching technology, specifically a precision punching device that is easy to operate. Background Technology

[0002] Punching is a production technology that uses the power of conventional or special punching equipment to directly subject sheet metal to deformation force in a die, thereby obtaining product parts with a certain shape, size and performance.

[0003] Most precision punching devices currently in use are not convenient for changing different molds and punching plates according to needs, making it inconvenient to punch materials. During use, the inconvenience of changing molds and punching plates leads to a cumbersome process, requiring a considerable amount of time and effort, making operation difficult and delaying subsequent punching work. This results in low efficiency and inconvenience in operation. Furthermore, the inability to punch materials smoothly may require multiple operations to complete a single punch, leading to poor work smoothness and low efficiency. The lack of illumination in the punching area makes it difficult for operators to accurately observe the relative position of the punch in low-light conditions, causing deviations in the punching position and affecting the dimensional and shape accuracy of the product, thus reducing the accuracy of the punching device.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model, by changing the punching mechanism, facilitates the replacement of molds and punching plates as needed, and also facilitates the punching of materials. During use, the mold and punching plate are replaced through the cooperation of the threaded rod and nut, and the threaded hole and bolt. The electric push rod then lowers the pressure plate to punch the material. This avoids the cumbersome process of changing molds and punching plates due to the inconvenience of changing different molds and punching plates as needed, which would otherwise require a long time and be inconvenient for operators, delaying subsequent punching work. This ensures the ease of operation and efficiency of the device, and also avoids situations where the punching process is not smooth due to the inconvenience of punching materials, requiring multiple operations to complete a single punch, resulting in poor work smoothness and low efficiency. Therefore, this device guarantees ease of operation and smooth punching.

[0015] 2. This utility model, through the setting of the lighting component, can achieve the function of illuminating the punching area. During use, by turning on the lighting to illuminate the punching area, it can avoid the situation where the operator cannot accurately observe the relative position of punching in some poor lighting environments due to the inability to illuminate the punching area, which would lead to deviations in the punching position and affect the dimensional and shape accuracy of the product, thus ensuring the accuracy of punching by the device.

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.

[0023] Example: Figure 1 As shown, the present invention provides the following technical solution, including a base 1, a replacement punching mechanism 2 is provided on the top of the base 1, a pressure plate 4 is slidably connected to the outer wall of the slide rail 201, the shape and size of the base 1 match the shape and size of the pressure plate 4, and the shape of the base 1 is rectangular, and lighting components 3 are provided at both ends of the base 1.

[0024] When the punching device is needed, the appropriate mold 205 and punching plate 211 need to be replaced according to the requirements. The appropriate mold 205 and punching plate 211 are replaced by the set punching replacement mechanism 2. After replacement, it is observed whether the light in the punching area is sufficient. If the light is insufficient, the punching area needs to be illuminated by the set lighting component 3. Then, the material is placed on the punching plate 211, and the punching of the material can begin. The material is punched by the set punching replacement mechanism 2 to complete the work.

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a replacement punching mechanism 2 is provided on the top of the base 1. The replacement punching mechanism 2 includes a slide rail 201. The slide rail 201 is fixedly connected to the top of the base 1. A baffle 202 is fixedly connected to the top of the slide rail 201. A pressure plate 4 is slidably connected to the outer wall of the slide rail 201. A support frame 203 is fixedly connected to one side of the base 1. An electric push rod 204 is fixedly connected to the bottom of the support frame 203. The bottom end of the electric push rod 204 is fixedly connected to the top of the pressure plate 4. A mold 205 is movably connected to the top of the base 1. Support plates 206 are fixedly connected to both ends of the base 1. A threaded rod 207 is fixedly connected to the top of the support plate 206. A locking block 208 is fixedly connected to both sides of the mold 205. A locking hole 209 is opened inside the locking block 208. The inner wall of the locking hole 209 fits against the outer wall of the threaded rod 207. The outer wall of rod 207 is threaded with a nut 210. The bottom of pressure plate 4 is movably connected with a punching plate 211. Both sides of punching plate 211 are fixedly connected with mounting plates 212. The interior of mounting plate 212 and pressure plate 4 are both provided with threaded holes 213. Bolts 214 are threadedly connected to the inner wall of threaded holes 213. There are four slide rails 201, and the slide rails 201 are circular. The support plate 206 is rectangular, and there are four support plates 206. The shape and size of the locking hole 209 match the shape and size of the threaded rod 207, and the locking hole 209 is circular. The mounting plate 212 is rectangular, and there are two sets of mounting plates 212, two in each set. The shape and size of the threaded hole 213 match the shape and size of the bolt 214, and the threaded hole 213 is circular.

[0026] When the punching device is needed, the appropriate mold 205 and punching plate 211 must first be replaced according to requirements. Then, rotate the nut 210 to remove it from the outer wall of the threaded rod 207. Next, pull out the locking block 208 from the outer wall of the threaded rod 207. Then, remove the appropriate mold 205 and align the locking hole 209 on the locking block 208 with the threaded rod 207. Insert the locking hole 209 into the outer wall of the threaded rod 207. Then, rotate the nut 210 into the outer wall of the threaded rod 207 to fix the locking block 208. Replace the new mold 205 on the base 1. Then, rotate the bolt 214 out of the threaded hole 213 to separate the mounting plate 212 from the pressure plate 4. Then, remove the punching plate 211 and place it tightly against the bottom of the pressure plate 4, corresponding to the mold 205. Simultaneously, ensure that the mounting plate 212 and the pressure plate 4 are tightly attached to both sides. Then, align the threaded hole 213 in the mounting plate 212 with the threaded hole 213 in the pressure plate 4. Then, rotate the bolt 214 and insert it into the threaded hole 213 to replace the appropriate punching plate 211, thus completing the replacement work. When it is necessary to punch the material, start the electric push rod 204 to extend it. The electric push rod 204 drives the pressure plate 4 to descend, and the pressure plate 4 drives the punching plate 211 to descend. During the descent of the punching plate 211, the sliding of the pressure plate 4 on the outer wall of the slide rail 201 makes the punching plate 211 rise and fall more smoothly. The baffle 202 ensures that the pressure plate 4 will not derail. Then, by aligning the punching plate 211 with the mold 205, the material is punched, thus completing the punching work.

[0027] like Figure 1 and Figure 5 As shown, lighting components 3 are provided at both ends of the base 1. The lighting components 3 include a fixing frame 301. The fixing frame 301 is fixedly connected to both ends of the base 1. A lighting lamp 302 is fixedly connected to one side of the fixing frame 301.

[0028] After replacement, observe whether the lighting in the punching area is sufficient. If the lighting is insufficient, the punching area needs to be illuminated by turning on the lighting lamp 302 to illuminate the punching area, thus completing the lighting work.

[0029] The working principle of this utility model is as follows: When the punching device is needed, firstly, the appropriate mold 205 and punching plate 211 need to be replaced according to the requirements. At this time, the nut 210 is rotated to rotate the nut 210 out from the outer wall of the threaded rod 207. Then, the locking block 208 is pulled out from the outer wall of the threaded rod 207. Then, the appropriate mold 205 is taken out, and the locking hole 209 on its locking block 208 is aligned with the threaded rod 207. Then, the locking hole 209 is inserted into the outer wall of the threaded rod 207. Nut 210 is rotated into the outer wall of threaded rod 207 to fix the retaining block 208. The new mold 205 is then replaced onto base 1. Bolt 214 is then rotated out of threaded hole 213 to separate mounting plate 212 from pressure plate 4. Punching plate 211 is then removed. The punching plate 211 corresponding to mold 205 is then pressed tightly against the bottom of pressure plate 4, while mounting plate 212 is pressed tightly against both sides of pressure plate 4. Finally, the threaded hole 213 in mounting plate 212 is aligned with the threaded hole 213 in pressure plate 4. Align the threaded holes 213, then rotate the bolt 214 into the threaded holes 213 to replace the appropriate punching plate 211, thus completing the replacement work. After replacement, observe whether the lighting in the punching area is sufficient. If the lighting is insufficient, the punching area needs to be illuminated by turning on the lighting lamp 302 to illuminate the punching area, thus completing the lighting work. Then place the material on the punching plate 211 to start punching the material. At this time, start the electric push rod 204 to extend the electric push rod 204 and drive the pressure plate 4 to start descending. The pressure plate 4 drives the punching plate 211 to start descending. During the descent of the punching plate 211, the sliding of the pressure plate 4 on the outer wall of the slide rail 201 makes the rise and fall of the punching plate 211 more stable and smooth. The baffle 202 can ensure that the pressure plate 4 will not derail. Then, by the overlap of the punching plate 211 and the mold 205, the material is punched, thus completing the punching work.
