Description

Technical Field

[0001] This utility model relates to the technical field of punch presses, and in particular to the technical field of punch press protective mechanisms. Background Technology

[0002] A punch press is a type of stamping press that is widely used in national production. Compared with traditional machining, stamping has advantages such as saving materials and energy, high efficiency, low operator skill requirements, and the ability to produce products that cannot be achieved by machining through the application of various molds. It is mainly used for sheet metal and can perform various processing such as blanking, punching, forming, and deep drawing. It is widely used in the production of parts for many products such as switches and sockets, cups, and computer cases.

[0003] Some punch presses lack protective devices. If operators put their hands, arms, or heads into the danger zone of the mold while working near the punch press, they may be crushed during the punching process, causing serious injury. Some punch presses also lack protective devices for the stamped parts. When the internal program of the punch press malfunctions and the pressure block applies excessive pressure to the stamped parts, the stamped parts may break, and the splashed fragments may injure the operators. Summary of the Invention

[0004] The purpose of this invention is to solve the problems in the prior art by proposing a punch press protection mechanism that can solve the above problems.

[0005] To achieve the above objectives, this utility model proposes a punch press protective mechanism, including a punch press body. A placement seat and a protective cover are provided at the processing station of the punch press body. The protective cover includes a protective panel, a left guard plate, and a right guard plate. The protective panel is disposed on the front of the placement seat. A left guard plate and a right guard plate are respectively disposed on the left and right sides of the protective panel. The left guard plate is threadedly installed with a drive threaded rod, which is driven to rotate by a drive motor. The drive threaded rod is rotatably mounted on the left side of the punch press body. The right guard plate is slidably installed with a guide rod, which is mounted on the right side of the punch press body. A cleaning brush is provided on the punch press body, located above the placement seat.

[0006] Preferably, the left guard plate is provided with a mounting plate, which is threaded onto the drive threaded rod, and the right guard plate is provided with a guide plate, which is slidably mounted on the guide rod.

[0007] Preferably, the protective panel has a viewing window.

[0008] Preferably, the placement base is provided with a proximity switch, and the bottom of the protective cover is provided with a sensor that matches the proximity switch.

[0009] Preferably, the shape of the cleaning brush matches the cross-section of the protective cover, and the bristles of the cleaning brush abut against the inner sidewall of the protective cover.

[0010] The beneficial effects of this utility model are as follows: By setting a liftable protective cover at the stamping station, this utility model can prevent workers from putting their body parts into the danger zone when the punch press is working, and can also block debris from flying, thus improving the safety of the punch press operation; when the protective cover is raised, the cleaning brush will automatically clean the inner wall of the protective cover to ensure the cleanliness of the protective cover.

[0011] The features and advantages of this utility model will be described in detail through embodiments and accompanying drawings. Attached Figure Description

[0014] See Figure 1 , Figure 2 , Figure 3 A punch press protective mechanism includes a punch press body 1. A placement seat 2 and a protective cover 3 are provided at the processing station of the punch press body 1. The protective cover 3 includes a protective panel 31, a left guard plate 32, and a right guard plate 33. The protective panel 31 is disposed on the front of the placement seat 2. The left guard plate 32 and right guard plate 33 are respectively disposed on the left and right sides of the protective panel 31. The left guard plate 32 is threadedly installed with a drive threaded rod 4, which is driven to rotate by a drive motor. The drive threaded rod 4 is rotatably installed on the left side of the punch press body 1. The right guard plate 33 is slidably installed with a guide rod 5, which is installed on the right side of the punch press body 1. A cleaning brush 6 is provided on the punch press body 1, and the cleaning brush 6 is located above the placement seat 2.

[0015] The left guard plate 32 is provided with a mounting plate 34, which is threaded onto the drive threaded rod 4. The right guard plate 33 is provided with a guide plate 35, which is slidably mounted on the guide rod 5.

[0016] The protective panel 31 has a viewing window.

[0017] The placement base 2 is equipped with a proximity switch, and the bottom of the protective cover 3 is equipped with a sensor that matches the proximity switch.

[0018] The stamping process will only proceed when the proximity switch detects the sensing element, ensuring operational safety.

[0019] The shape of the cleaning brush 6 matches the cross-section of the protective cover 3, and the bristles of the cleaning brush 6 abut against the inner sidewall of the protective cover 3.

[0020] After the stamping is completed, the protective cover rises. During the rising process, the bristles of the cleaning brush that matches the protective cover will come into contact with the inner wall of the protective cover and automatically clean off the remaining debris.

[0021] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
