Description

Technical Field

[0001] This utility model relates to the field of metal parts processing technology, and in particular to a punching device for metal parts processing. Background Technology

[0002] Punching equipment is a type of machinery used to process holes of specific shapes in metal, plastic, paper, or other sheet materials. It uses the cooperation of a die and a punch to break the material by mechanical pressure or hydraulic power, thereby forming the desired hole shape. It is widely used in industries such as automobile manufacturing, aerospace, building decoration, and electronics to produce products such as screens, heat dissipation holes, and decorative panels. Its characteristics include high processing efficiency, precise hole shape, and strong repeatability. It can change the die according to different needs to achieve diverse hole diameters and arrangements, making it one of the indispensable basic processing equipment in modern industrial production.

[0003] In the field of metal parts processing, punching is a common forming process. However, most traditional punching devices on the market have functional limitations; their stamping mechanisms can usually only process workpieces in a single fixed direction. Therefore, when punching multiple different surfaces of metal parts, such as the sides and tops, it is inevitable that after each processing step, the workpiece must be removed from the fixture, its posture readjusted, and then re-clamped before punching in another direction can be performed. This repeated clamping and disassembly process not only consumes a lot of auxiliary time and increases the labor intensity of operators, but also affects the final processing accuracy due to the accumulation of repeated positioning errors, thus seriously restricting the overall processing efficiency and product quality of metal parts. Utility Model Content

[0004] One objective of this invention is to provide a punching device for processing metal parts. This invention addresses the problem mentioned in the background that when punching multiple different surfaces of metal parts, such as the sides and tops, it is inevitable to complete one processing step, then remove the workpiece from the fixture, readjust its posture, and re-clamp it before punching in another direction. This repeated clamping and disassembly process not only consumes a lot of auxiliary time and increases the labor intensity of operators, but also affects the final processing accuracy due to the accumulation of repeated positioning errors, thus seriously restricting the overall processing efficiency and product quality of metal parts.

[0005] A punching device for processing metal parts according to an embodiment of the present invention includes a processing table, an upper punching mechanism, a side punching mechanism, and a limiting mechanism. The upper punching mechanism includes a top plate, a sliding plate, and a first punch. The top plate is fixedly installed on the upper surface of the processing table, the sliding plate is slidably installed on the lower part of the top plate, and the first punch is fixedly installed on the lower surface of the sliding plate. The side punching mechanism includes a diagonal rod, a fixed block, and a slider. The fixed block is fixedly installed on both sides of the upper surface of the processing table, the slider is slidably installed on the inner side of the fixed block, and a second punch is fixedly installed on the inner side of the slider. The diagonal rod is fixedly installed on both sides of the lower surface of the sliding plate and is slidably installed through the inside of the slider.

[0006] Preferably, the lower surface of the processing table is fixedly equipped with support legs at all four corners.

[0007] Preferably, four sets of limiting rods are fixedly installed on the upper surface of the processing table, the top plate is fixedly installed on the upper end of the limiting rods, a hydraulic rod is fixedly installed on the lower surface of the top plate, the sliding plate is slidably installed on the surface of the limiting rods, and the sliding plate is fixedly installed on the telescopic end of the hydraulic rod.

[0009] Preferably, a toothed block is fixedly installed inside the slide rail, and gears are rotatably installed on both sides of the slider, with the gears meshing with the toothed block.

[0010] Preferably, a limit block is fixedly installed at the lower end of the diagonal rod.

[0011] Preferably, the limiting mechanism includes an inner support block and an outer clamping ring, both of which are fixedly installed on the middle part of the upper surface of the processing table.

[0012] Preferably, both sides of the outer clamping ring are provided with through holes.

[0013] The beneficial effects of this utility model are: This utility model, through the setting of an upper punching mechanism and a side punching mechanism, drives the sliding plate to slide downward by the extension of the hydraulic rod. At the same time, the first punch on the lower surface of the sliding plate punches the upper surface of the metal parts, while the sliding plate drives the inclined rod to slide downward. The inclined rod is installed inside the slider by sliding obliquely, thereby pulling the sliders on both sides to slide synchronously towards the middle. The second punch on the inner side of the sliders on both sides achieves the purpose of punching the two sides of the metal parts. By linking the upper punching and side punching mechanisms, multi-surface synchronous punching is achieved, reducing the number of clamping times, improving processing efficiency and accuracy, and reducing labor intensity. This utility model, through the setting of a limiting mechanism, allows for the selection of a corresponding limiting mechanism to be installed on the surface of the processing table before processing, based on the shape of the metal parts to be processed. The inner support block provides inner support to the inner side of the metal parts to be processed, while the outer clamping ring provides outer clamping stability to the outer side of the metal parts, achieving double clamping from both inside and outside, enhancing processing stability, improving positioning accuracy, and adapting to the processing needs of various types of metal parts. This invention utilizes gears and toothed blocks to ensure smooth sliding of the slider as it is pulled towards the center or sides by the oblique force of the inclined rod. The gears roll on the surface of the toothed blocks, preventing jamming and improving the reliability and machining accuracy of the mechanism. Attached Figure Description

[0015] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0016] refer to Figure 1-4A punching device for processing metal parts includes a processing table 1, an upper punching mechanism 3, a side punching mechanism 4, and a limiting mechanism 5. The upper punching mechanism 3 includes a top plate 302, a sliding plate 304, and a first punch 305. The top plate 302 is fixedly installed on the upper surface of the processing table 1, the sliding plate 304 is slidably installed on the lower part of the top plate 302, and the first punch 305 is fixedly installed on the lower surface of the sliding plate 304. The side punching mechanism 4 includes a diagonal rod 409, a fixing block 401, and a slider 405. The fixing block 401 is fixedly installed on both sides of the upper surface of the processing table 1, the slider 405 is slidably installed on the inner side of the fixing block 401, and a second punch 408 is fixedly installed on the inner side of the slider 405. The diagonal rod 409 is fixedly installed on both sides of the lower surface of the sliding plate 304. The 09 is slidably installed inside the slider 405. Through the upper punching mechanism 3 and the side punching mechanism 4, the extension of the hydraulic rod 303 drives the sliding plate 304 to slide downward. At the same time, the first punch 305 on the lower surface of the sliding plate 304 punches the upper surface of the metal parts, while the sliding plate 304 drives the inclined rod 409 to slide downward. The inclined rod 409 is obliquely installed inside the slider 405, thereby pulling the sliders 405 on both sides to slide synchronously towards the middle. The second punch 408 on the inner side of the sliders 405 on both sides achieves the purpose of punching the two sides of the metal parts. By linking the upper punching and side punching mechanisms 4, multi-surface synchronous punching is achieved, reducing the number of clamping operations, improving processing efficiency and accuracy, and reducing labor intensity.

[0017] Example 1: Support legs 2 are fixedly installed at the four corners of the lower surface of the processing table 1. Four sets of limiting rods 301 are fixedly installed on the upper surface of the processing table 1. A top plate 302 is fixedly installed on the upper end of the limiting rods 301. A hydraulic rod 303 is fixedly installed on the lower surface of the top plate 302. A sliding plate 304 is slidably installed on the surface of the limiting rods 301, and the sliding plate 304 is fixedly installed on the telescopic end of the hydraulic rod 303. A limiting groove 402 is formed on the inner side of the fixing block 401. A slider 405 is slidably installed inside the limiting groove 402. A slide rail 403 is formed on the lower inner surface of the limiting groove 402. The slide rail 403 has a toothed block 404 fixedly installed inside. Gears 406 are rotatably installed on both sides of the slider 405. The gears 406 and the toothed block 404 mesh with each other. Through the gears 406 and the toothed block 404, when the slider 405 is pulled to the center or to the sides by the oblique force of the inclined rod 409, the gears 406 roll on the surface of the toothed block 404, so that the slider 405 slides more smoothly and will not have a jamming problem, improving the reliability of the mechanism and the machining accuracy. The lower end of the inclined rod 409 is fixedly installed with a limit block 407.

[0018] Example 2: The limiting mechanism 5 includes an inner support block 501 and an outer clamping ring 502. Both the inner support block 501 and the outer clamping ring 502 are fixedly installed on the middle part of the upper surface of the processing table 1. Both sides of the outer clamping ring 502 are provided with through holes 503. With the setting of the limiting mechanism 5, before processing, the corresponding shape of the limiting mechanism 5 can be selected according to the shape of the metal part to be processed and installed on the surface of the processing table 1. The inner support block 501 provides inner support to the inner side of the metal part to be processed, and the outer clamping ring 502 provides outer clamping stability to the outer side of the metal part, realizing double clamping inside and outside, enhancing processing stability, improving positioning accuracy, and adapting to the processing needs of various types of metal parts.

[0019] In use, firstly, select a suitable limiting mechanism 5 according to the shape of the metal parts to be processed. Fix the inner support block 501 and outer clamping ring 502 onto the surface of the processing table 1. The inner support block 501 internally supports the workpiece, while the outer clamping ring 502 externally clamps and fixes it, ensuring stable positioning of the workpiece. Activate the hydraulic rod 303. The hydraulic rod 303 extends, causing the sliding plate 304 to slide downwards along the limiting rod 301. The first punch 305 on the lower surface of the sliding plate 304 descends accordingly, punching holes on the upper surface of the metal parts. Simultaneously, the inclined rods 409 on both sides of the sliding plate 304 move downwards synchronously. The inclined rods 409 pull the slider 405 within the limiting groove 402 of the fixed block 401 through oblique sliding force. The gears 406 on both sides of the slider 405 mesh and roll with the toothed blocks 404 in the slide rail 403, making the slider 405 slide more smoothly and preventing jamming. Both sliders 405 slide synchronously towards the center under the drive of the inclined rod 409, and the second punch 408 inside the slider 405 punches holes on both sides of the metal parts. Throughout the process, the upper punching mechanism 3 and the side punching mechanism 4 operate in conjunction to achieve simultaneous punching of multiple surfaces, reducing the number of clamping operations, improving processing efficiency and accuracy, and reducing labor intensity. The double clamping of the limiting mechanism 5 ensures the stability of workpiece processing, and the rolling cooperation between the gear 406 and the tooth block 404 improves the reliability of the mechanism operation, ultimately completing the efficient and high-precision punching process of the metal parts.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
