Description

Technical Field

[0001] This utility model relates to the field of punching equipment technology, and in particular to a novel punching mechanism for punching machines. Background Technology

[0002] The new punching mechanism is a high-efficiency, precise, and intelligent punching execution system developed based on traditional punching technology and combined with advanced technologies in modern mechanical design, automation control, and materials science. It is mainly used to quickly and accurately punch holes of preset shapes and sizes in metal and non-metal materials, and is widely used in industrial fields such as automobile manufacturing, aerospace, electronics, and hardware processing.

[0003] The patent application "202420899109.2" entitled "A Novel Punching Mechanism for a Punch Press" describes a device that uses a push rod to push a punching block, which in turn pushes a punching plate, which in turn pushes a punch rod to punch holes. This device effectively improves structural strength by distributing the force across the punching plate and the punching block. A lower pressure plate is provided at the lower end of the punching plate, and a sliding sleeve is provided on the lower pressure plate. The sliding sleeve is slidably connected to the sliding rod, which serves as a guide and limiter for the device, preventing the punch rod from shifting and causing damage. This effectively extends the service life of the device and enhances its practicality.

[0004] However, the device has the following problems when in use: the electric push cylinder of the device is fixed in position and cannot be moved, which means that when punching different positions of the template is required, the template needs to be moved frequently, which reduces the punching efficiency of the template. In addition, the device does not have a device to limit the template, and the template is prone to displacement during the punching process, which reduces the accuracy of punching. Utility Model Content

[0005] The purpose of this invention is to provide a novel punching mechanism for a punch press, which solves the problems of existing punching devices where the electric push cylinder is fixed in position and cannot be moved, thus requiring frequent movement of the template when punching different positions of the template, reducing the punching efficiency of the template, and the lack of a device to limit the template, causing the template to easily shift during the punching process, thereby reducing the punching accuracy.

[0006] To achieve the above objectives, a novel punching mechanism for a punch press is provided, comprising: a punch press body, a support leg fixedly connected to the bottom of the punch press body, a mounting plate 1 fixedly connected to the top of the punch press body, a servo motor 1 fixedly mounted on the outer side of the mounting plate 1, a lead screw 1 fixedly connected to the output end of the servo motor 1 via a coupling, a guide rod 1 fixedly connected to the inner sides of the two mounting plates 1, a bracket movably connected to the outer wall of the lead screw 1 and the guide rod 1, a servo motor 2 fixedly mounted on one side of the bracket, a lead screw 2 fixedly connected to the output end of the servo motor 2 via a coupling, a guide rod 2 fixedly connected to the inner side of the bracket, a slider movably connected to the outer wall of the lead screw 2 and the guide rod 2, a hydraulic rod fixedly connected to the bottom of the slider, and a punch rod fixedly connected to the output end of the hydraulic rod, facilitating the adjustment of the punch rod position, allowing the punch rod to punch holes at any position on the top of the template without needing to move the template multiple times, thus improving punching efficiency;

[0007] A mounting plate two is fixedly connected to the top of the punch press body. A cylinder is fixedly connected to the inner side of the mounting plate two. A moving plate is fixedly connected to the output end of the cylinder. A clamping groove is opened on the inner side of the moving plate. A sleeve is fixedly connected to the inner wall of the clamping groove. A spring is fixedly connected inside the sleeve. A telescopic rod is fixedly connected to the other end of the spring. A clamping block is fixedly connected to the other end of the telescopic rod. Screws are provided at both ends of the moving plate. A controller is provided on one side of the bracket to facilitate the clamping of the template and prevent it from shifting during the punching process, thereby improving the stability of the punching process.

[0008] According to the novel punching mechanism, a drain hole is provided on the top of the punch body, and a collection box is movably connected inside the punch body to facilitate the collection of debris.

[0009] According to the novel punching mechanism, a screw hole is provided at the center of the bottom end of the bracket. The inner wall of the screw hole is provided with threads, and the screw hole engages with the lead screw through the threads, which facilitates the back-and-forth movement of the bracket.

[0010] According to the novel punching mechanism, a second screw hole is provided at the center of the side of the slider, and the inner wall of the second screw hole is provided with threads. The second screw hole and the second lead screw are engaged with each other through threads, which facilitates the left and right movement of the slider.

[0011] According to the novel punching mechanism, the bottom end of the support and the side of the slider are respectively provided with through hole one and through hole two. The support and the slider are slidably connected to the outer walls of guide rod one and guide rod two through through hole one and through hole two, respectively, which facilitates the guidance and positioning of the support and the slider.

[0012] According to the novel punching mechanism, both ends of the moving plate are provided with screw holes three. The screw holes three and the outer wall of the screw rod are both provided with threads. The screw holes three and the screw rod are engaged with each other through threads, which facilitates the movement of the clamping block and thus facilitates the clamping of the template.

[0013] According to the novel punching mechanism of the punch press, a rotating shaft seat is fixedly installed on one side of the mounting plate, the inner side of the bracket, and one side of the clamping block. One end of the lead screw, lead screw 2, and screw is rotatably connected to the rotating shaft seat, which facilitates the rotation of lead screw 1, lead screw 2, and screw.

[0014] The above-mentioned solution has the following beneficial effects:

[0015] 1. This new type of punching machine uses a servo motor to drive the lead screw to rotate, which in turn drives the support to move back and forth. A second servo motor is installed on one side of the support, which drives the lead screw to rotate, which in turn drives the slider to move left and right. A hydraulic rod and a punch rod are installed at the bottom of the slider, facilitating the forward, backward, left, and right movement of the punch rod. This allows the punch rod to punch holes at any position on the top of the template without moving the template, improving punching efficiency. Furthermore, a perforation hole is installed at the top of the punching machine body, and a collection box is installed at the bottom of the perforation hole. Debris generated during punching can enter the collection box through the perforation hole, facilitating debris collection.

[0016] 2. This new type of punching machine has a cylinder installed on the top of the punching machine body. The cylinder drives the movement of the moving plate. At the same time, a clamping groove is opened inside the moving plate. The clamping groove is equipped with a screw and a clamping block. By rotating the screw, the clamping block can be moved. In this way, the templates of different sizes can be clamped and limited by four clamping blocks to prevent them from shifting during the punching process and improve the stability of the punching process.
