Technical Field
[0001] This utility model relates to the field of press technology, specifically to an automatic anti-fall device for an automatic door of a press. Background Technology
[0002] A press is a sophisticated and versatile machine. It is characterized by its wide range of applications and high production efficiency. Presses can be widely used in processes such as cutting, punching, blanking, bending, riveting, and forming. They process metal parts by applying strong pressure to metal blanks, causing plastic deformation and fracture. Safety precautions must be taken for personnel and other protective measures according to the function of the press.
[0003] During the use of the press, the safety door needs to be opened and closed. If the safety door is damaged during the opening process, it may fall and cause injury to the workers.
[0004] To address these shortcomings, an automatic anti-fall device for automatic doors of presses is proposed, which is an upgrade and modification of the existing device. Utility Model Content
[0005] The purpose of this utility model is to provide an automatic anti-fall device for automatic doors of presses in order to solve the problems in the background technology.
[0006] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:
[0007] An automatic anti-fall device for an automatic door of a press includes a frame. A safety door is slidably connected to the inner side of the frame. A sliding plate is slidably connected to the inner wall of the safety door. A connecting rod is fixedly connected to the upper end of the sliding plate. A steel wire rope is fixedly connected to the upper end of the connecting rod extending out of the safety door. A driving device is connected to the upper end of the steel wire rope extending into the interior of the frame. A groove is formed on the inner side of the frame. A movable groove is formed on the right side of the groove. A rotating tube is rotatably connected to the bottom of the inner wall of the movable groove. A piston rod is slidably connected to the inner wall of the rotating tube. A baffle is rotatably connected to the upper side of the inner wall of the groove at one end of the baffle. A hook is fixedly connected to the upper side of the other end of the baffle. A fixing groove is formed on the lower side of the safety door near the baffle for the outer end of the hook to engage.
[0008] Furthermore, guide blocks are fixedly connected to both sides of the outer end of the safety door, and guide grooves are provided on the inner side of the frame for the outer ends of the guide blocks to slide and connect.
[0009] Furthermore, transmission rods are fixedly connected to both sides of the lower end of the sliding plate. A cavity is opened at the lower end of the transmission rod. A rotating rod is provided on the inner wall of the cavity. The outer end of the rotating rod is rotatably connected to the inner wall of the safety door. One end of the rotating rod abuts against a sliding rod. One end of the sliding rod extends out of the safety door and is fixedly connected to a stop block. The lower end of the stop block is at the outer end of the fixed groove.
[0010] Furthermore, the outer end of the safety door is provided with a sliding groove for sliding connection of the outer end of the slide rod, and an elastic pad is fixedly installed on the inner wall of the safety door, with one end of the elastic pad fixedly installed to one side of the upper end of the slide rod.
[0011] Furthermore, elastic blocks are fixedly installed on both sides of the upper end of the sliding plate, and the upper end of the elastic blocks is fixedly installed to the inner wall of the safety door.
[0012] Furthermore, the inner side of the frame is provided with a sliding groove for the outer end of the stop to slide.
[0013] The beneficial effects of this utility model are as follows:
[0014] This invention utilizes the action of an elastic block to press the sliding plate downwards, and with the added weight of the sliding plate itself, the sliding plate drives the transmission rod to move downwards, causing the rotating rod to drive the stop block at one end of the sliding rod to move upwards, exposing the fixing groove. Through the cooperation of the rotating tube and the piston rod, one end of the stop plate is kept in contact with the safety door until the hook connects with the fixing groove, which facilitates the fixing of the safety door that is moving downwards and prevents the safety door from falling accidentally.
[0015] This invention utilizes the cooperation of a rotating tube and a piston rod to position the baffle at the bottom of the safety door. This allows the safety door to be blocked by the baffle at the start of the fall, preventing it from moving downwards slowly and providing more time for the baffle to open upwards, thus improving the safety of the device.

[0026] like Figures 1 to 5As shown, an automatic anti-fall device for an automatic door of a press includes a frame 1. A safety door 10 is slidably connected to the inner side of the frame 1. A sliding plate 111 is slidably connected to the inner wall of the safety door 10. A connecting rod 11 is fixedly connected to the upper end of the sliding plate 111. A steel wire rope 12 is fixedly connected to the upper end of the connecting rod 11 extending out of the safety door 10. A driving device is connected to the upper end of the steel wire rope 12 extending into the interior of the frame 1. A groove 152 is formed on the inner side of the frame 1. A movable groove 151 is formed on the right side of the groove 152. A rotating tube 153 is rotatably connected to the bottom of the inner wall of the movable groove 151. A piston rod 154 is slidably connected to the inner wall of the rotating tube 153. The upper end of the piston rod 154 passes through the rotating tube 153 and is rotatably connected to a baffle 156. One end of the baffle 156 near the groove 152 is rotatably connected to the upper side of the inner wall of the groove 152. A hook 155 is fixedly connected to the upper side of the other end of the baffle 156. A fixing groove 102 for the outer end of the hook 155 to be engaged is opened on the lower side of the end of the safety door 10 near the baffle 156. Guide blocks 13 are fixedly connected to both sides of the outer end of the safety door 10. A guide groove 14 for the outer end of the guide block 13 to be slidably connected is opened on the inner side of the frame 1.
[0027] Specifically, by cooperating with the rotating tube 153 and the piston rod 154, one end of the baffle 156 is always in contact with the safety door 10 until the hook 155 is connected to the fixing groove 102, which facilitates fixing the safety door 10 that is moving downward and prevents the safety door 10 from falling accidentally. The guide block 13 and the guide groove 14 enable stable movement.
[0028] like Figure 1 , Figure 4 and Figure 5 As shown, transmission rods 113 are fixedly connected to both sides of the lower end of the sliding plate 111. A cavity 115 is opened at the lower end of the transmission rod 113. A rotating rod 114 is provided on the inner wall of the cavity 115. The outer end of the rotating rod 114 is rotatably connected to the inner wall of the safety door 10. One end of the rotating rod 114 abuts against a slide rod 104. One end of the slide rod 104 extends out of the safety door 10 and is fixedly connected to a stop block 100. The lower end of the stop block 100 is at the outer end of the fixing groove 102. Specifically, the weight of the sliding plate 111 itself causes the sliding plate 111 to drive the transmission rod 113 to move downward, causing the rotating rod 114 to drive the stop block at one end of the slide rod 104 to move upward, exposing the fixing groove 102.
[0029] like Figure 4 and Figure 5 As shown, elastic blocks 112 are fixedly installed on both sides of the upper end of the sliding plate 111, and the upper end of the elastic blocks 112 is fixedly installed on the inner wall of the safety door 10; specifically, the sliding plate 111 is pressed downward by the action of the elastic blocks 112.
[0030] like Figure 2 , Figure 3 and Figure 4 As shown, the outer end of the safety door 10 is provided with a sliding groove 101 for the outer end of the sliding rod 104 to slide and connect. An elastic pad 103 is fixedly installed on the inner wall of the safety door 10. One end of the elastic pad 103 is fixedly installed on one side of the upper end of the sliding rod 104. Specifically, this facilitates the stable movement of the sliding rod 104 and makes it easy for the sliding rod 104 to return to its original position through the elastic pad 103.
[0031] like Figure 1 , Figure 2 and Figure 3 As shown, a groove 15 is provided on the inner side of the frame 1 for the outer end of the stop block 100 to slide and connect; specifically, this facilitates the movement of the stop block 100.
[0032] In summary: During operation, before the automatic door falls, the safety door 10 moves upward via the steel wire rope 12. At this time, the piston rod 154 is pressed against the rotating tube 153. When the safety door 10 reaches its uppermost position, the cooperation between the rotating tube 153 and the piston rod 154 causes the baffle 156 to be positioned at the bottom of the safety door 10. When the safety door 10 falls, it is blocked by the baffle 156, preventing it from moving downwards slowly. The connecting rod 11 and the sliding plate 111 move downwards, and the elastic block 112 acts as a buffer. The sliding plate 111 is pressed downwards, and the weight of the sliding plate 111 itself is added, causing the sliding plate 111 to drive the transmission rod 113 to move downwards, causing the rotating rod 114 to drive the stop block at one end of the sliding rod 104 to move upwards, exposing the fixing groove 102. Through the cooperation of the rotating tube 153 and the piston rod 154, one end of the baffle 156 is kept in contact with the safety door 10 until the hook 155 is connected to the fixing groove 102, so as to fix the safety door 10 that is moving downwards and prevent the safety door 10 from falling.
[0033] By cooperating with the rotating tube 153 and the piston rod 154, the baffle 156 is always in contact with the safety door 10, so that the safety door 10 will not fall down quickly even when it has not reached the top.
[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
