Description

Technical Field

[0001] This utility model relates to the field of punch press technology, and in particular to a punch press safety protection mechanism. Background Technology

[0002] A punch press is a type of stamping press. In industrial production, stamping processes are increasingly widely used due to their advantages over traditional machining, including saving materials and energy, high efficiency, lower operator skill requirements, and the ability to produce products that cannot be achieved through machining, thanks to the application of various molds. Stamping production is primarily for sheet metal. Using molds, it can produce blanking, punching, forming, deep drawing, trimming, fine blanking, shaping, riveting, and extruded parts, etc., and is widely used in various fields.

[0003] When a small punch press completes the stamping process, the loading and unloading operations are usually performed manually by the worker. To improve operational safety, punch presses are typically equipped with safety protection devices, such as detection probes to check for foreign objects intruding into the stamping die area, thus reducing the risk of worker injury. However, current technology relies solely on detection gratings, which still poses a risk of unreliable detection and worker hand injuries during stamping. Secondly, when the punch press completes the stamping process, the workpiece may be ejected outwards under pressure, posing a risk of worker injury.

[0004] Therefore, how to design a punch press safety protection mechanism with a simpler and more reasonable structure that can better prevent workpieces from popping out and intruding into the work area, and can better improve operational safety, has become a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of the above-mentioned deficiencies of the prior art, the technical problem to be solved by this utility model is how to design a punch press safety protection mechanism with a simpler and more reasonable structural design, which can better prevent the workpiece from popping out and intruding into the working area, and can better improve the operational safety.

[0006] To achieve the above objectives, this utility model provides a safety protection mechanism for a punch press, including detection gratings mounted on the left and right sides above the front end of the punch press worktable via an installation structure, and the detection gratings being connected to the punch press controller; characterized in that; it also includes a rotation drive mechanism mounted on the punch press via a support structure, a stop plate installed at the working end of the rotation drive mechanism, the rotation drive mechanism being able to drive the stop plate to rotate vertically and block the front of the stamping die on the punch press to prevent the stamped workpiece from being ejected by force to the outside of the stamping die; a two-hand push-button switch is installed in front of the punch press worktable; and the controller is electrically connected to the electrical control end of the rotation drive mechanism and the two-hand push-button switch.

[0007] In this way, when the aforementioned safety protection mechanism for the punch press is in operation, the worker places the part to be processed on the punch press die, and then retracts their hand. Two detection gratings detect that there is no obstruction between them (the worker's arm), and the detection gratings send the detected signal to the controller. Simultaneously, the worker presses two buttons on each hand-operated push-button switch. The push-button switches send signals to the controller, which then controls the rotary drive mechanism to rotate the stop plate vertically, blocking the front of the punch press die to prevent the workpiece from being ejected from the front of the die. The punch press then processes the part. After processing, the controller controls the rotary drive mechanism to rotate the stop plate vertically back to its original position, and the worker removes the processed part.

[0008] The aforementioned structure, by incorporating a stop plate, can block workpieces ejected during punching, preventing injury and improving operational safety, as well as preventing workers' hands from entering the workpiece. Secondly, the requirement to press the two-hand button switch with both hands further avoids placing hands in a dangerous area during processing, further enhancing operational safety.

[0009] As an optimization, the two-hand push-button switch is installed on the front surface of the workbench.

[0010] This arrangement of the two-hand button switch on the front surface of the workbench is more reasonable, safer, and easier to operate.

[0011] As an optimization, a protective plate with a horizontal arrangement and a rectangular plate structure is installed above the two-hand button switch on the front surface of the workbench, and the upper surface of the protective plate is flush with the upper surface of the workbench.

[0012] In this way, by setting up a protective plate, the two-hand button switch can be protected, making the design more reasonable.

[0013] As an optimization, the inner middle part of the protective plate is bent downward to form a mounting plate. The mounting plate is attached to the front end of the workbench and fixed to the workbench by connecting screws.

[0014] This makes the structural design simpler and more reasonable, and also makes the installation and disassembly of the protective structure easier.

[0015] As an optimization, the installation structure includes mounting strips respectively installed on the left and right sides of the upper surface of the workbench. The front end of the mounting strip is bent outward to form a support strip, and the outer end of the support strip is bent upward vertically to form a fixing strip. The detection grating is installed on the inner side of the fixing strip.

[0016] This makes the installation structure design simpler and more reasonable, and makes it easier to install the detection grating.

[0017] As an optimization, the drive mechanism includes a rotary cylinder, a connecting rod is installed at the rotation drive end of the rotary cylinder, and the stop plate is installed at the far end of the connecting rod.

[0018] In this way, the drive mechanism adopts a rotary cylinder, and the structural design is simpler and more reasonable.

[0019] As an optimization, the stop plate is designed as a circular plate structure.

[0020] This makes the stop plate design more reasonable.

[0021] As an optimization, the support structure includes an L-shaped mounting plate. The mounting plate includes a vertical section that is fixed to the punch press and an integrally formed horizontal section that is set at the upper end of the vertical section. The far end of the horizontal section is bent at 90 degrees to form a mounting section. A rotation drive mechanism is installed on the mounting section.

[0022] This simplifies the support structure design and makes it easier to install the drive mechanism.

[0023] In summary, the above structure, by incorporating a detection grating, a stop plate, and a two-hand push-button switch, can better prevent workpieces from ejecting and intruding into the work area, thus improving operational safety. Attached Figure Description

[0032] In this way, when the aforementioned safety protection mechanism for the punch press is in operation, the worker places the part to be processed on the punch press die, and then retracts their hand.

Secondly, the requirement to press the two-hand button switch with both hands further avoids placing hands in a dangerous area during processing, further enhancing operational safety.

[0034] In this specific embodiment, the two-hand push-button switch is installed on the front surface of the workbench.

[0035] This arrangement of the two-hand button switch on the front surface of the workbench is more reasonable, safer, and easier to operate.

[0036] In this specific embodiment, a protective plate 5 with a rectangular plate structure is installed above the two-hand button switch on the front surface of the workbench, and the upper surface of the protective plate is flush with the upper surface of the workbench.

[0037] In this way, by setting up a protective plate, the two-hand button switch can be protected, making the design more reasonable.

[0038] In this specific embodiment, the inner middle part of the protective plate is bent downward to form a mounting plate 6. The mounting plate is attached to the front end surface of the workbench and fixed to the workbench by connecting screws.
