Description

Technical Field

[0001] This utility model relates to the field of punch press technology, specifically to a punch press with a pneumatic safety door. Background Technology

[0002] A punch press is a mechanical device used for metal processing. It is typically used to cut, shape, and punch metal sheets and is widely used in automobile manufacturing, home appliance manufacturing, aerospace and other fields.

[0003] The shortcomings of existing punch presses:

[0004] Inefficient use of space: Traditional punch press safety doors often adopt a left-right opening and closing design, which requires a large external space to realize the opening and closing operation, resulting in low space utilization. This is especially true for long-span punch presses, where the space occupied is even more significant.

[0005] Inconvenient to operate: The safety door that opens and closes to the left and right requires additional external space to perform the opening and closing action, which is cumbersome to operate and is easily affected by external environmental factors, such as narrow factory space or obstruction by surrounding equipment, resulting in inconvenience to operation.

[0006] Poor stability: Due to the complex structure of the safety door of traditional punch presses, the opening and closing action depends on the coordinated movement of multiple components, which can easily lead to asynchronous or unstable opening and closing, affecting production efficiency and safety.

[0007] Low safety: Traditional punch press safety doors pose certain safety hazards during opening and closing. For example, excessively fast or asynchronous opening and closing speeds may lead to accidental injuries. In addition, some structures may have gaps or sharp edges, increasing the safety risks for operators.

[0008] Therefore, this solution proposes a punch press with a pneumatic safety door to solve the above problems. Summary of the Invention

[0009] To overcome the shortcomings of the prior art, the purpose of this utility model is to provide a punch press with a pneumatic safety door.

[0010] To achieve the aforementioned objective, the technical solution of this utility model is as follows: a punch press with a pneumatic safety door, comprising a punch press, wherein two vertically parallel protective door plates are distributed on the front of the punch press, and the two protective door plates are closed to fully open and close the punching working space of the punch press, and pneumatic opening and closing mechanisms are installed at both the left and right ends of the punch press.

[0018] The cylinder telescopic rods are symmetrically distributed, and the telescopic ends of the two cylinder telescopic rods are respectively connected to one end of the inner side of the two connecting rods;

[0019] Hinged seats are installed on the same side wall of the stamping machine tool for mounting the two cylinder telescopic rods;

[0020] An air guide pipe connecting the air supply cylinder and the cylinder extension rod.

[0021] Preferably, the air supply cylinders inside the air supply drive mechanisms on both sides start and stop synchronously and have the same air output.

[0022] Preferably, the front of the stamping machine tool is provided with guide components near the left and right edges to cooperate with the opening and closing operation of the upper and lower protective door panels.

[0023] Preferably, the guiding component specifically includes the following structure:

[0024] Vertical guide rails are vertically distributed on one side edge of the front of the stamping machine tool;

[0028] Preferably, both of the protective door panels are provided with observation windows made of tempered glass.

[0029] Preferably, the inner sides of the rear ends of the two connecting rods are also provided with guide teeth, and the two guide teeth are slidably engaged with the interior of two arc-shaped guide rails provided on the same side wall of the stamping machine.

[0030] The beneficial effects of this utility model are reflected in:

[0031] High space utilization: The pneumatic safety door adopts an up-and-down opening design, which saves space around the machine compared with the traditional left-and-right opening design.

If the specific posture changes, the directional indicators will also change accordingly.

[0053] Furthermore, "multiple" refers to two or more. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of a person skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by the utility model.

[0054] Please refer to the instruction manual appendix. Figures 1-6 This utility model provides a punch press with a pneumatic safety door, including a punch press 1. The front of the punch press 1 has two vertically parallel protective door plates 2. When the two protective door plates 2 are closed, the punch press 1 can be fully opened and closed to open the punching working space. Pneumatic opening and closing mechanisms 3 are installed at both the left and right ends of the punch press 1.

[0055] The pneumatic opening and closing mechanism 3 includes:

[0056] Two connecting rods 32 are intersectingly distributed on the side wall of the stamping machine tool 1;

[0057] The central connecting shaft 33 is aligned with the intersection of the connecting rods 32.

[0058] The telescopic rod heads 34 are connected to the front ends of the two connecting rods 32, and the front ends of the two telescopic rod heads 34 are respectively hinged to the same side of the two protective door panels 2.

[0059] An air supply drive mechanism 31, installed on the same side wall of the stamping machine tool 1, drives the two connecting rods 32 to move in a cross motion;

[0060] The air supply drive mechanism 31 can drive two connecting rods 32 to perform a scissor motion, and then drive the upper and lower protective door plates 2 to open and close through the telescopic rod head 34 at its front end, thereby realizing the closed protection or opening operation of the working space of the stamping machine tool 1.

[0061] Both sides of the air supply drive mechanism 31 include the following structure:

[0062] Air supply cylinder 311 is installed on the same side wall as the stamping machine tool 1;

[0063] Symmetrically distributed cylinder telescopic rods 313, with the telescopic ends of two cylinder telescopic rods 313 respectively connected to one end of the inner side of two connecting rods 32;

[0064] Hinged seats 314 are installed on the same side wall of the stamping machine tool 1 for mounting the two cylinder telescopic rods 313;

[0065] An air guide pipe 312 connects the air supply cylinder 311 and the cylinder extension rod 313;

[0066] The air supply cylinder 311 supplies air to the two cylinder extension rods 313 on the same side simultaneously through the air guide pipe 312, so that they extend synchronously, thereby realizing the operation of adjusting the included angle between the two connecting rods 32, and thus realizing the scissor movement operation, which can drive the upper and lower protective door panels 2 to open and close. The hinge seat 314 is designed to provide the end of the cylinder extension rod 313 with a rotatable corner, ensuring that there is no movement interference when the angle of the pushing connecting rod 32 is adjusted.

[0067] The air supply cylinders 311 inside the air supply drive mechanisms 31 on both sides start and stop synchronously and have the same air output.

[0068] This design ensures that the pneumatic opening and closing mechanisms 3 on both sides can synchronously drive the two protective door panels 2 to open and close, thus ensuring the stability of the opening and closing.

[0069] The front of the stamping machine tool 1 is equipped with guide components 5 near the left and right edges to cooperate with the opening and closing of the upper and lower protective door panels 2.

[0070] The guide component 5 specifically includes the following structure:

[0071] Vertical guide rails 51 are vertically distributed on the front side of the stamping machine tool 1 near one edge;

[0072] Guide rod 52 installed inside the vertical guide rail 51;

[0073] Two guide sleeves 53 are slidably sleeved on the guide rod 52, and the two guide sleeves 53 are respectively fixedly connected to the upper and lower two protective door panels 2 on the same side;

[0074] The guide rod 52 and guide sleeve 53 in the guide assembly 5 are designed to improve the movement stability of the upper and lower protective door panels 2 during opening and closing operations.

[0075] The two protective door panels 2 are provided with buffer pads 21 at their closed edges.

[0076] Both of the protective door panels 2 are equipped with observation windows 22 made of tempered glass.

[0077] The inner side of the rear end of each of the two connecting rods 32 is also provided with guide teeth 321, and the two guide teeth 321 are slidably engaged with the interior of the two arc-shaped guide rails 4 provided on the same side wall of the stamping machine tool 1.

[0078] The arc-shaped guide rail 4 and the guide tooth 321 are designed to improve the stability of the scissor movement of the two connecting rods 32.

[0079] The specific opening and closing operation is as follows

[0080] When it is necessary to close and protect the working space of the stamping machine tool 1, the air supply cylinders 311 inside the pneumatic opening and closing mechanisms on both sides are activated simultaneously to recover gas. At this time, the air supply cylinders 311 simultaneously draw air from the two cylinder telescopic rods 313 on the same side through the air guide pipe 312, so that they are recovered synchronously, thereby reducing the included angle between the two connecting rods 32, and thus realizing the scissor movement operation. At this time, the distance between the two telescopic rod heads 34 at the front end becomes smaller, which drives the upper and lower protective door plates 2 to converge towards the center, ultimately realizing the operation of closing and shielding the working space of the stamping machine tool 1. Compared with the traditional left and right opening safety door, it saves more space, especially for stamping machines with a long span. The traditional left and right opening safety door requires more external space to realize its opening and closing operation. This upper and lower opening safety door is customized according to the length of the stamping machine, and the opening and closing operation is only carried out in the front space of the machine tool, which requires extension to the external space.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
