Description

Technical Field

[0001] This utility model relates to the field of punch press technology, and in particular to a punch press safety bolt mechanism for mechanical punch presses and a punch press using the same. Background Technology

[0002] The statements in this section are merely background information related to this application and do not necessarily constitute prior art.

[0003] Punch presses, especially high-speed punch presses, typically have a slide stroke rate far exceeding 200 strokes per minute, currently reaching over 3000 strokes per minute. Therefore, the dies wear out quickly, requiring frequent replacement or repair. Furthermore, punch presses have a wide range of processes, necessitating continuous die replacements for the same press due to process variations. Thirdly, test-press punch presses require die repairs on the press itself, requiring operators to work between the punch press slide and the worktable. To prevent injury to personnel working between the punch press slide and the worktable in case of a broken connecting rod assembly or malfunction of the balancing device (not shown in the diagram), supporting devices need to be added to the slide and the worktable or upper and lower dies during punch press maintenance. These devices support the slide in case of an accident and prevent injury. The punch press safety bolt mechanism is specifically designed to support the slide in case of an accidental fall, thus protecting personnel.

[0004] In existing technologies, the safety bolt mechanism for punch presses is generally installed between the upper and lower dies (which are separated during die maintenance and replacement); some also install it between the slide and the worktable. Safety bolts can be adjustable or non-adjustable. Non-adjustable bolts have a narrow processing range and cannot meet the protection requirements for dies of different heights. Existing adjustable safety bolts, although employing automatic rotation mechanisms, are too complex and bulky, unsuitable for small and medium-sized punch presses. Furthermore, when repairing dies, the safety bolt needs to be placed between the worktable and the slide; if the operator is negligent or temporarily leaves the punch press, an unsuspecting person might start the press, creating a safety hazard. Therefore, it is essential to research a convenient, practical, and safe safety bolt suitable for small and medium-sized punch presses.

[0005] Therefore, how to solve the safety bolt problem of the punch press becomes the subject of this utility model. Utility Model Content

[0006] The purpose of this utility model is to provide a safety bolt mechanism for a punch press and a punch press using the same.

[0007] To achieve the above objectives, the first aspect of this utility model provides a punch press safety bolt mechanism, which includes a support base, an adjustable support sleeve, an adjustable support column, and control electrical components.

[0008] The adjustable support sleeve is detachably and combinably installed on the support base, and the adjustable support column is mounted on the adjustable support sleeve with adjustable vertical height.

[0009] The control electrical components include connectors, plugs, and sockets. The connectors are mounted on the support base or adjustable support sleeve and are connected to the plugs. The sockets are mounted on the machine tool body and can be detachably and combinably connected.

[0010] To achieve the above objectives, a second aspect of this utility model provides a punch press, which has a machine body and a worktable, a slider component, and a die mounted on the machine body.

The support base is mounted on the fixed base. The control electrical components include a connector, a plug, and a socket. The plug and socket are connected to the electrical control system. When the plug is inserted into the socket, the electrical control system supplies power to the punch press. When the plug is separated from the socket, the electrical control system disconnects power from the punch press.

[0011] The relevant contents of this utility model are explained as follows:

[0012] 1. The implementation of the above-mentioned technical solution of this utility model addresses the problems that existing conventional safety bolts are bulky, unsuitable for small and medium-sized punch presses, and prone to safety hazards when using safety bolts. Therefore, an innovative punch press safety bolt mechanism suitable for small and medium-sized punch presses is designed, as well as a punch press using the punch press safety bolt mechanism. This punch press safety bolt mechanism comprises a support base, an adjustable support sleeve, an adjustable support column, and control electrical components. The adjustable support sleeve is detachably mounted on the support base, allowing for easy access and removal by the operator. When used on small to medium-sized punch presses, the support base, adjustable support sleeve, and adjustable support column can be removed separately, saving effort and increasing convenience. The control electrical components are also included. In use, the plug is disconnected from the socket, keeping the punch press powered off. Specifically, once the support base of the safety bolt is removed from the punch press mounting base, the plug disengages from the socket, immediately stopping the punch press and preventing accidental startup, thus avoiding safety hazards. In the non-use state, when the safety bolt mechanism is placed on the punch press mounting base, the plug connects to the socket, allowing the punch press to be powered on and started. This innovative design makes the punch press safety bolt mechanism highly suitable for small to medium-sized punch presses, offering convenience, practicality, and safety, thereby enhancing overall safety.

[0013] 2. In the first aspect of the above technical solution, the punch press has a machine body and a worktable, a slider component, and a mold disposed on the machine body. The mold includes an upper mold and a lower mold. A fixed seat for placing the support base is disposed on the machine body.

[0014] 3. In the first aspect of the above technical solution, in the use state, the support base, adjustable support sleeve, and adjustable support column are installed between the slide block component and the worktable of the punch press or between the upper and lower dies of the punch press, and the plug is separated from the socket. This ensures that the punch press is always powered off when using the punch press safety bolt mechanism, preventing accidental start-up of the punch press.

[0015] 4. In the first aspect of the above technical solution, in the unused state, the support base, adjustable support sleeve, and adjustable support column are installed in the fixed seat, and the plug and socket are connected together. This allows the punch press to be powered on and started, and also allows the punch press safety bolt mechanism to be placed in the same fixed position when not in use, making it convenient for operators to use.

[0016] 5. In the first aspect of the above technical solution, the socket is located on one side of the fixed base, the connector is a long, flexible member, one end of the connector is connected to the support base via a pin, and the other end is connected to the plug. The connector can be a chain or rope-like object, with a plug at the end of the connector to facilitate plugging into the socket and to facilitate plug removal when using the punch press safety bolt mechanism.

[0017] 6. In the first aspect of the above technical solution, the socket is disposed on the fixed base, the connector is an insulating component, and the connector is disposed on the side or bottom of the support base. In use, the support base can be directly removed to separate the plug from the socket; when not in use, the support base can be directly inserted into the fixed base, which is convenient and quick.

[0018] 7. In the first aspect of the above technical solution, the support base is an aluminum alloy structure, and the support base is provided with an assembly groove for assembling the adjustable support sleeve. A fixing screw passes through the support base to securely connect the adjustable support sleeve assembled in the assembly groove. The support base, as the lower part of the punch press safety bolt mechanism, is made of aluminum alloy to reduce weight and make it easier to use. The use of an assembly groove and fixing screws to fix the adjustable support sleeve, and the division into upper and lower parts, makes it more convenient to remove.

[0019] 8. In the first aspect of the above technical solution, the adjustable support column is an alloy steel columnar structure, and the column body is provided with external threads; the adjustable support sleeve is a hollow cylindrical structure, and the inner wall of the adjustable support sleeve is provided with internal threads, wherein the external and internal threads are mutually mating trapezoidal threads. The use of an alloy steel columnar adjustable support column and a hollow cylindrical adjustable support sleeve aims to increase strength and reduce weight, wherein the mutually mating trapezoidal threads can improve the ability to withstand large forces.

[0020] 9. In the second aspect of the above technical solution, the punch press further includes a transmission structure and a connecting rod assembly, the connecting rod assembly being mounted on the upper part of the machine body, and the transmission structure driving the slide block component to move through the connecting rod assembly.

[0021] Due to the application of the above solution, this utility model has the following advantages and effects compared with the prior art:

[0022] 1. Through the implementation of the technical solution of this utility model, the safety bolt mechanism of the punch press is configured to have a support base, an adjustable support sleeve, an adjustable support column, and control electrical components. The adjustable support sleeve can be detachably and combined and installed on the support base, so that the safety bolt mechanism of the punch press can be easily picked up and put down by the operator.
