Detailed Description

The present invention will be described with reference to specific embodiments.

Fig. 1 is the assembly schematic diagram of the protection device, as shown in fig. 1, the protection device is arranged in the working mechanism 1, the working mechanism 1 comprises: the device comprises a lower die 11, an upper die 12, a support column 13 fixed at the top of the lower die 11 and a working column 112 fixed on the lower die 11, wherein a press plate 131 is connected to the top of the support column 13 in a sliding manner.

The protection device of the utility model also comprises: and a protective seat 2 positioned right below the pressing plate 131. The protective seat 2 is fixed on the top of the lower die 11, and the working column 112 is fixed in the protective seat 2. The protective seat 2 is provided with a first air cushion 31, and the working column 112 is wrapped by the first air cushion 31. A rubber pad 22 is fixed on the top of the protection seat 2.

During operation, the working box 122 is pressed downwards to contact the pressure plate 131, so that the pressure plate 131 moves downwards to compress the spring, after the processing is completed, the upper die 12 moves upwards, and the spring pushes the pressure plate 131 to reset. If a fault occurs, the upper die 12 cannot return and continues to be pressed down to contact with the lower die 11, which may hurt a worker who takes the workpiece. Therefore, the protection seat 2 is arranged below the pressure plate 131 for artificial limit. When the pressing plate 131 moves to come into contact with the top of the protection seat 2, it does not move down further. A certain space is left between the upper die 12 and the lower die 11, so that when a fault occurs, firstly, the safety of workers is ensured, and then the equipment is maintained. Meanwhile, the rubber pad 22 is provided on the protection seat 2 to absorb the vibration caused by the contact, and the first air pad 31 plays a role of reducing the momentum. And also to reinforce the working column 112 with the protection socket 2.

Guide posts 111 are arranged at four corners of the top of the lower die 11, a working post 112 is arranged in the center of the lower die, and a guide sleeve 121 is arranged at the bottom of the upper die 12. The guide sleeve 121 is disposed corresponding to the guide post 111, and the guide sleeve 121 is slidably connected to the guide post 111. A second air cushion 32 is fixedly mounted on the lower die 11, and the second air cushion 32 wraps the guide post 111. The second air cushion 32 is used for further reducing the momentum, and the function of protecting the guide device is achieved, so that the later maintenance is convenient.

Fig. 2 is a structural view of a protection seat, and fig. 3 is a half sectional view of the protection seat, and as shown in fig. 2 and 3, the top surface of the protection seat 2 is provided with a fixing groove 21, and the first air mat 31 is installed in the fixing groove 21. The contact area of the pressing plate 131 and the protection seat 2 is reduced due to the arrangement of the fixing groove 21, the limiting effect is achieved, the shock absorption effect is achieved, and the device is protected from being impacted too much.

As shown in fig. 2, the plurality of rubber pads 22 are uniformly arranged along the groove edge of the fixing groove 21. The rubber pad 22 is uniformly arranged, so that the pressure from the pressing plate 131 to the rubber pad 22 can be dispersed, and the effect of absorbing impact is achieved.

As shown in fig. 3, the height of the protection seat 2 is less than half of the height of the work column 112. Since the pressing plate 131 is pressed down during machining, the height of the protective base 2 cannot exceed one-half of the height of the work column 112, and a certain machining space is reserved in order to prevent the protective base 2 from interfering with the machining of the work column 112.

It will be apparent to those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims and their equivalents, the present invention is also intended to include such modifications and variations.
