Abstract
Description
Technical Field
[0001] This utility model belongs to the field of metal cover processing technology, and more specifically, it relates to a high-efficiency stamping and forming device for metal covers. Background Technology
[0002] When producing metal covers, a servo-driven punch press is used to stamp and form the metal covers. During the operation of the punch press, the operator needs to frequently check data such as the motor temperature, actual pressure, and lead screw position of the touch screen. If an overload warning or overheating occurs, the machine must be stopped immediately for inspection.
[0003] For example, CN220161032U discloses a metal processing cap stamping forming machine, belonging to the field of metal processing technology. It includes a base platform, a support frame fixedly installed on the left side of the base platform, two electric push rods fixedly installed on the upper surface of the support frame, a hydraulic telescopic arm fixedly installed on the upper surface of each electric push rod, a corner plate fixedly installed on the right side of each hydraulic telescopic arm, a servo motor fixedly installed on the side of the two corner plates that are far apart from each other, a cylinder fixedly installed at the output end of each servo motor, and a clamping plate fixedly installed at the telescopic end of each cylinder. A storage slot is provided on the left side of the base platform. This metal processing cap stamping forming machine, by setting up a base platform, support frame, electric push rods, hydraulic telescopic arms, corner plates, servo motors, cylinders, clamping plates, storage slot, and programmable controller, utilizes the electric push rods, hydraulic telescopic arms, and cylinders to automatically lift, move, and clamp caps.
[0004] Based on the above, when starting the punch press, it is necessary to ensure that the slide is at the top dead center to prevent the motor from being overloaded at the moment of starting. However, in actual operation, the operator may start the punch press directly due to negligence or operational error, which may cause the motor to overload and malfunction, affecting the normal operation of the punch press and requiring the punch press to be stopped for maintenance, thus affecting the processing efficiency of the metal cover. Utility Model Content
[0005] To address the aforementioned technical problems, this utility model provides a high-efficiency stamping and forming device for metal covers. This device solves the problem that when starting the press, it is necessary to ensure the slide is at the top dead center to prevent motor overload. However, in actual operation, workers may easily start the press directly due to negligence or operational errors, leading to motor overload and malfunction, affecting the normal operation of the press, requiring it to be shut down for maintenance, and impacting the processing efficiency of the metal covers.
[0006] The purpose and effectiveness of this utility model's high-efficiency stamping and forming device for metal machine covers are achieved through the following specific technical means: A high-efficiency stamping forming device for metal covers includes a punch press body, a limiting mounting plate, a swing baffle plate, a positioning structure, an emergency stop structure, a start button, a stop button, and a limiting baffle plate. A moving die mounting frame is slidably connected to the upper part of the punch press body, and the limiting mounting plate is bolted to the front side of the moving die mounting frame. The swing baffle plate is hinged to the lower part of the limiting mounting plate. The positioning structure is located on the front side of the limiting mounting plate. The start button is located on the right side of the punch press body and is connected in series with the punch press's control circuit. The stop button is located on the right side of the punch press body and is connected in series with the punch press's control circuit. The limiting baffle plate is rotatably connected to the front side of the limiting mounting plate. The emergency stop structure is located on the lower side of the punch press body.
[0007] Furthermore, the positioning structure includes a limiting mounting rod, a limiting magnetic plate, and a positioning magnetic plate; the limiting mounting rod is fixedly connected to the front side of the limiting mounting plate; the limiting magnetic plate is fixedly connected to the front side of the limiting mounting rod; and the positioning magnetic plate is fixedly connected to the front side of the swing shield.
[0008] Furthermore, the emergency stop structure includes a first sliding rod and a first reset elastic element; the first sliding rod is slidably connected to the lower side of the punch press body; the first sliding rod is elastically connected to the punch press body through the first reset elastic element.
[0009] Furthermore, the emergency stop structure also includes a first electromagnet and a first metal plate; the first electromagnet is fixedly connected to the lower side of the punch press body, and the control circuit of the first electromagnet is connected in series with the control circuit of the punch press; the first metal plate is fixedly connected to the front side of the first sliding rod.
[0010] Furthermore, the emergency stop structure also includes a conductive metal plate and a conductive metal block; the conductive metal plate is fixedly connected to the rear side of the first sliding rod; two conductive metal blocks are provided, and both conductive metal blocks are fixedly connected to the lower side of the punch press body.
[0011] Furthermore, the emergency stop structure also includes a second sliding rod and a second reset elastic element; the second sliding rod is slidably connected to the lower side of the punch press body; the second sliding rod is elastically connected to the punch press body through the second reset elastic element.
[0012] Furthermore, the emergency stop structure also includes a second metal plate, a second electromagnet, and an emergency stop button; the second metal plate is fixedly connected to the rear side of the second sliding rod; the second electromagnet is fixedly connected to the lower side of the punch press body, and the two conductive metal blocks are connected in series with the control circuit of the second electromagnet through wires; the emergency stop button is located on the lower side of the punch press body, and the emergency stop button is connected in series with the control circuit of the punch press; a solid-state relay is connected in series in the control circuit of the second electromagnet, and the stop button is connected in series with the solid-state relay.
[0013] Compared with the prior art, the present invention has the following beneficial effects: This invention uses a limiting mounting plate and a swing shield to block the start button, preventing the punch press from starting under load due to operator negligence or operational errors. This avoids motor malfunction due to instantaneous overload during startup, reduces the frequency of punch press downtime for maintenance, ensures the continuity of the metal cover processing flow, and minimizes the impact of equipment failure on processing efficiency. During normal shutdown checks, pressing the stop button allows for a smooth stop of the punch press. Simultaneously, circuit linkage ensures that the second electromagnet will not be accidentally activated, preventing damage to transmission components such as the lead screw from accidental triggering of the emergency stop button. If the stop button malfunctions and the punch press power is not properly cut off, the second sliding rod will automatically press the emergency stop button, quickly cutting off the punch press circuit, ensuring the safety of the equipment and operators. This avoids the situation where frequent misuse of the emergency stop button causes increased transmission clearance in the lead screw drive pair, avoids the need for frequent punch press shutdowns for adjustments, and improves the processing efficiency of metal covers.

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. Example 1
[0022] As attached Figure 1 To be continued Figure 2 As shown: This utility model provides a high-efficiency stamping forming device for metal covers, including a punch press body 1, a limiting mounting plate 2, a swing baffle plate 3, a positioning structure, a start button 4, a stop button 5, and a limiting baffle plate 6; a moving mold mounting frame is slidably connected to the upper part of the punch press body 1, and the limiting mounting plate 2 is bolted to the front side of the moving mold mounting frame; the swing baffle plate 3 is hinged to the lower part of the limiting mounting plate 2; the positioning structure is set on the front side of the limiting mounting plate 2; the start button 4 is set on the right side of the punch press body 1, and the start button 4 is connected in series with the control circuit of the punch press; the stop button 5 is set on the right side of the punch press body 1, and the stop button 5 is connected in series with the control circuit of the punch press; the limiting baffle plate 6 is rotatably connected to the front side of the limiting mounting plate 2.
[0023] The positioning structure includes a limiting mounting rod 201, a limiting magnetic plate 202, and a positioning magnetic plate 301; the limiting mounting rod 201 is fixedly connected to the front side of the limiting mounting plate 2; the limiting magnetic plate 202 is fixedly connected to the front side of the limiting mounting rod 201; and the positioning magnetic plate 301 is fixedly connected to the front side of the swing shield plate 3.
[0024] The specific usage and function of this embodiment are as follows: When processing the metal cover, the moving mold mounting bracket will drive the moving mold to move up and down to stamp the metal cover. When the moving mold and the fixed mold are closed, the moving mold mounting bracket will drive the limiting mounting plate 2 and the swing baffle plate 3 to move downward along the main body 1 of the punch press. At this time, the swing baffle plate 3 will block the outside of the start button 4. After the moving mold mounting bracket moves the moving mold upward to the top dead center position, the swing baffle plate 3 will move above the start button 4. Only then can the operator press the start button 4 to avoid the punch press starting under load and causing the motor to malfunction. If the punch press malfunctions and the moving mold mounting bracket cannot move upward and the start button 4 needs to be repaired, the limiting baffle plate 6 is rotated. At this time, the swing baffle plate 3 is no longer limited. The swing baffle plate 3 is flipped upward so that the positioning magnetic plate 301 and the limiting magnetic plate 202 on the front side of the limiting mounting rod 201 are attracted together, fixing the position of the swing baffle plate 3 and facilitating the repair of the start button 4. Example 2
[0025] As attached Figure 3 To be continued Figure 6 As shown: Based on Embodiment 1, an emergency stop structure is also included; the emergency stop structure is located on the lower side of the punch press body 1.
[0026] The emergency stop structure includes a first sliding rod 102 and a first reset elastic element 104; the first sliding rod 102 is slidably connected to the lower side of the punch press body 1; the first sliding rod 102 is elastically connected to the punch press body 1 through the first reset elastic element 104.
[0027] The emergency stop structure also includes a first electromagnet 101 and a first metal plate 103; the first electromagnet 101 is fixedly connected to the lower side of the punch press body 1, and the control circuit of the first electromagnet 101 is connected in series with the control circuit of the punch press; the first metal plate 103 is fixedly connected to the front side of the first sliding rod 102.
[0028] The emergency stop structure also includes a conductive metal plate 105 and a conductive metal block 106; the conductive metal plate 105 is fixedly connected to the rear side of the first sliding rod 102; two conductive metal blocks 106 are provided, and both conductive metal blocks 106 are fixedly connected to the lower side of the punch press body 1.
[0029] The emergency stop structure also includes a second sliding rod 107 and a second reset elastic element 108; the second sliding rod 107 is slidably connected to the lower side of the punch press body 1; the second sliding rod 107 is elastically connected to the punch press body 1 through the second reset elastic element 108.
[0030] The emergency stop structure also includes a second metal plate 109, a second electromagnet 110, and an emergency stop button 111. The second metal plate 109 is fixedly connected to the rear side of the second sliding rod 107. The second electromagnet 110 is fixedly connected to the lower side of the punch press body 1, and two conductive metal blocks 106 are connected in series with the control circuit of the second electromagnet 110 through wires. The emergency stop button 111 is located on the lower side of the punch press body 1 and is connected in series with the control circuit of the punch press. A solid-state relay is connected in series in the control circuit of the second electromagnet 110, and the stop button 5 is connected in series with the solid-state relay.
[0031] The specific usage and function of this embodiment are as follows: When a shutdown inspection is required, pressing the stop button 5 will stop the punch press normally. At this time, the power supply to the punch press control circuit is cut off, the first electromagnet 101 loses its magnetic force, and the first reset elastic element 104 will pull the first sliding rod 102 to slide backward. At this time, the conductive metal plate 105 moves backward and is misaligned with the conductive metal block 106, thus disconnecting the circuit of the second electromagnet 110. When the stop button 5 is pressed, the control signal generated by the stop button 5 triggers the solid-state relay, causing the electronic switch inside the solid-state relay to close, connecting the power supply circuit of the second electromagnet 110. At this time, the circuit of the second electromagnet 110 is in the open state, and the second electromagnet 110 cannot be started. The stop button 5 malfunctions... When the power supply to the punch press is not cut off, the first electromagnet 101 will not be de-energized. At this time, the circuit of the second electromagnet 110 is in the on state. When the solid-state relay connects the power supply circuit of the second electromagnet 110, the second electromagnet 110 starts and generates magnetic force to attract the second metal plate 109, causing the second metal plate 109 to drive the second sliding rod 107 to slide backward. When the second sliding rod 107 moves backward, it will press the emergency stop button 111 to cut off the punch press circuit. After the punch press circuit is disconnected, the second reset elastic element 108 will drive the second sliding rod 107 to reset. After the punch press is repaired, starting the punch press will energize the first electromagnet 101 to attract the first metal plate 103, causing the first metal plate 103 to drive the first sliding rod 102 to move forward and reset.
