DETAILED DESCRIPTION

[0025] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments, but is not intended to limit the present invention.

[0026] Example 1: Safety isolation device to prevent misoperation, see Figure 1-Figure 5As shown, a punch press 1 and a stamping die 101 are included, a workpiece placement platform is provided on the punch press 1, a stamping die 101 is slidably provided on the punch press 1, the stamping die 101 slides longitudinally on the punch press 1, and the stamping die 101 is located directly above the workpiece placement platform. Six guide columns 301 are fixedly connected to both sides of the lower part of the punch press 1 by welding, and a foot pedal 2 is slidably provided on the guide columns 301 on the same side, and the foot pedal 2 slides up and down along the guide columns 301. A first elastic member 3 for pushing the foot pedal 2 to slide upward is wound around the guide columns 301, and a limit plate 201 is installed on both sides of the punch press 1 by welding, and the bottom of the foot pedal 2 and the limit plate 201 are fixedly connected to ... A first electromagnet group 6 is installed on the top of the positioning plate 201 by bolt connection, and the first electromagnet group 6 is electrically connected to the stamping die 101. Pressure rods 4 are slidably arranged on both sides of the punch press 1. A second elastic member 5 is fixedly connected between the pressure rod 4 and the punch press 1 by welding. The second elastic member 5 is used to push the pressure rod 4 to slide upward and reset. A second electromagnet group 7 is installed between the pressure rod 4 and the punch press 1 by bolt connection, and the second electromagnet group 7 is electrically connected to the stamping die 101. The first electromagnet group 6, the second electromagnet group 7 and the stamping die 101 are connected in series with each other. When one group of electromagnets is not in contact, the punch press 1 cannot be started to avoid accidental start.

[0027] When the punch press 1 needs to be used, the two foot pedals 2 need to be stepped on at the same time to make the foot pedals 2 slide downward along the guide column 301. At this time, the first elastic member 3 is compressed and deformed by force to make the second electromagnet group 7 contact. At the same time, the two pressure rods 4 need to be pressed with both hands to make the pressure rods 4 slide downward on the punch press 1. At this time, the second elastic member 5 is compressed and deformed by force to make the first electromagnet group 6 contact. At this time, the circuit of the punch press 1 is connected, and then the stamping die 101 slides downward to punch the sheet. At this time, all four limbs of the staff are used to operate the punch press 1, and the stamping die 101 is not easy to cause harm to the staff.

[0028] Example 2: Based on Example 1, refer to Figure 2 As shown, it also includes a double-axis cylinder 8 installed on the upper front side of the punch press 1 by bolt connection, and the push rods on both sides of the double-axis cylinder 8 are installed with limit frames 9 for limiting the stamping die 101 by bolt connection.

[0029] When it is necessary to start the punch press 1 and use the stamping die 101, first start the double-axis cylinder 8 to push the limit frames 9 on both sides to move away from each other, so that the limit frames 9 on both sides are separated from the limit of the stamping die 101, and then start the punch press 1; when the punch press 1 is shut down, the double-axis cylinder 8 is controlled to drive the limit frames 9 on both sides to move toward each other, so that the two limit frames 9 limit the stamping die 101 to prevent the punch press 1 from being accidentally started and causing the stamping die 101 to be pressed down, causing harm to people.

[0030] See also Figure 6 As shown, it also includes a temperature sensor 10 embedded in the two pressure rods 4, the temperature sensor 10 is electrically connected to the first electromagnet group 6, and two alarms 11 are installed on the lower front side of the punch press 1 by bolt connection, and the two temperature sensors 10 are electrically connected to the two alarms 11 respectively.

[0031] When the staff is lazy and uses other objects instead of hands to press down the pressure rod 4, and makes the first electromagnet group 6 contact each other to be energized, the temperature sensor 10 on the pressure rod 4 cannot detect the human body temperature. The temperature sensor 10 sends a control signal to the alarm 11, causing the alarm 11 to emit a sharp alarm sound to alert other staff to prevent the staff from being injured by the stamping die 101 and ensure personal safety.

[0032] See also Figure 6 As shown, it also includes a support frame 12 installed together on the two limit plates 201 by bolt connection, and a bidirectional screw 13 is rotatably arranged on the support frame 12. L-shaped blocks 14 for limiting and supporting the limit plates 201 are slidably arranged on the two limit plates 201, and the two L-shaped blocks 14 are threadedly connected to the bidirectional screw 13.

[0033] When the punch press 1 needs to be used, the bidirectional screw 13 is first rotated on the support frame 12 so that the bidirectional screw 13 drives the two L-shaped blocks 14 to slide away from each other on the limit plate 201 for the first time, so that the two L-shaped blocks 14 are released from the limit on the foot pedal 2. When the punch press 1 is not in use, the bidirectional screw 13 is rotated in the opposite direction so that the two L-shaped blocks 14 limit and support the two foot pedals 2 to prevent the foot pedal 2 from being too heavy and causing the first elastic member 3 to be in a load-bearing compression state for a long time, causing the first elastic member 3 to lose its elasticity, and at the same time preventing misoperation.

[0034] See also Figure 1 , Figure 5 and Figure 6 As shown, an isolation cover 15 is slidably provided on the workpiece placement platform of the punch press 1, and a protective shell 16 is slidably provided on the punch press 1. The protective shell 16 is jointly sleeved on the outside of the two pressure rods 4. A telescopic sleeve 17 is jointly provided between the foot pedal 2 and the limit plate 201 by riveting, and the telescopic sleeve 17 is sleeved on the outside of the second electromagnet group 7. The isolation cover 15 can protect the stamping die 101 and prevent the punch press 1 and the stamping die 101 from being damaged by collision. The protective shell 16 is used to protect the first electromagnet group 6 and the temperature sensor 10 from damage. The telescopic sleeve 17 is compressed and stretched as the foot pedal 2 slides up and down, and is used to protect the second electromagnet group 7 and prevent dust.
