Description

TECHNICAL FIELD

[0001] The utility model relates to material rack opening and closing device technical field, concretely is a material rack automatic opening and closing device. BACKGROUND

[0002] When the H-shaped steel is laser cutting, the material rack supporting the H-shaped steel is usually opened and closed by manpower, so that the H-shaped steel can be supported and clamped. This way is time-consuming and laborious, and affects the processing time.

[0003] In order to realize automation, the existing material rack gradually realizes automatic control and automatic opening and closing through the application of sensors and motors. This way indeed greatly improves the efficiency of supporting and clamping the H-shaped steel and shortens the processing time. However, during use, it is found that even if automation can be realized, corresponding problems will follow. When the H-shaped steel is supported, the length of the H-shaped steel sometimes cannot be completely clamped by the first supporting plate. That is, during clamping, part of the first supporting plate will not be in contact with the H-shaped steel. Therefore, when clamping, the first supporting plate not in contact with the H-shaped steel will change in stress. After a long time, it is easy to cause multiple groups of first supporting plates not to be in the same horizontal plane, and part of the first supporting plates not in contact will tilt. If the tilted first supporting plate supports the H-shaped steel, due to the change in stress, the nut fixing the first supporting plate will be blocked and increased, causing the second mounting plate to be damaged or deformed, directly affecting the movement of the whole moving structure. Therefore, there is a certain hidden danger. Secondly, the existing automatic opening and closing device is an integral device. Therefore, when manufacturing, if a device with a length of 15m is needed, the device frame must be 15m long. During manufacturing, the device frame will produce fertilizer, which cannot be directly used. Therefore, to a certain extent, material is wasted.

[0004] Therefore, in order to realize multi-section clamping, prevent the first supporting plate not in contact with the H-shaped steel from changing in stress and affecting the subsequent moving structure, and realize the assembly type combination of the device frame, thereby saving raw materials to a certain extent, the utility model provides a material rack automatic opening and closing device to solve the technical problems existing in the existing automatic opening and closing device.
