AI Technical Summary
When the air supply of existing pressing machines is cut off, the upper and lower pressing mechanisms will suddenly fall, resulting in a high risk of injury to the operator.
A cylinder-type pressing machine anti-crushing mechanism is designed. By utilizing the cooperation of the second cylinder and the spring, the telescopic rod of the second cylinder drives the block to stop the upper pressing plate from falling, thereby preventing it from injuring the operator.
This effectively prevents operators from being injured by the upper pressure plate when the gas source is cut off, thereby improving the safety of the equipment.

Stamping technology is increasingly used in domestic production due to its advantages over traditional machining, including material and energy conservation, high efficiency, low operator skill requirements, and the ability to create products that are not possible with machining through the use of various molds. Stamping primarily targets sheet metal parts. Using molds, it can produce blanking, punching, forming, drawing, trimming, fine blanking, shaping, riveting, and extrusion, among other applications, across a wide range of fields. However, existing stamping equipment can cause the upper plate to fall when the upper and lower pressing mechanisms are deactivated, potentially causing injury to the operator. Utility Model Content

[0013] Example 2. A cylinder press machine anti-compression injury mechanism, the cylinder press machine includes a support frame 5, a first cylinder 6, an upper pressure plate 7 and a lower pressure plate 8, the first cylinder 6 and the lower pressure plate 8 are installed on the support frame 5; the upper pressure plate 7 is located above the lower pressure plate 8, the upper pressure plate 7 is connected to the second piston 10 of the first cylinder 6, and the first cylinder 6 is connected to the air source; it includes a mounting frame 4, a second cylinder 3, a spring 2 and a stopper 1, the second cylinder 3 is connected to the air source, the mounting frame 4 is installed on the support frame 5, the second cylinder 3 is installed on the mounting frame 4, the stopper 1 is connected to the second piston 10 of the second cylinder 3, the stopper 1 is located on one side of the upper pressure plate 7 and the lower pressure plate 8, the spring 2 is sleeved on the telescopic rod 11 of the second cylinder 3, one end of the spring 2 abuts the mounting frame 4, and the other end of the spring 2 abuts the stopper 1.
[0014] The second cylinder 3 includes a cylinder body 12, one end of the cylinder body 12 is provided with an exhaust port 9, the other end of the cylinder body 12 is provided with an air inlet 14, and the second piston 10 of the second cylinder 3 is located between the air inlet 14 and the exhaust port 9; a baffle 13 is provided between the second piston 10 and the air inlet 14 in the cylinder body 12, and the baffle 13 is fixed to the inner wall of the cylinder body 12.
[0015] The working principle of one embodiment of the present invention is as follows: when the upper platen 7 is lifted, the operator needs to load the material and place the component to be processed between the upper platen 7 and the lower platen 8. If the air source is suddenly cut off at this time, the upper platen 7 will fall rapidly under the action of gravity and hit the operator's hand, causing injury to the operator. In this application, the first cylinder 6 and the second cylinder 3 use the same air source. The air source is cut off at the same time. When the upper platen 7 falls, the second cylinder 3 also cuts off the air. The telescopic rod 11 of the second cylinder 3 is converted from a retracted state to an extended state under the action of the spring 2, so that the block 1 blocks the bottom of the upper platen 7 and prevents the upper platen 7 from falling further.
