Technical Field
[0001] The present invention relates to the technical field of compact shelving production, and in particular to a processing device for compact shelving production. Background Art
[0002] Compact shelving is a type of intensive storage equipment that moves on tracks. It adopts a double-column double-sided fixed frame structure, with axle wheels installed at the base, which can move in a straight line along the small guide rails laid on the ground. The core design of the compact shelving is to transform fixed channels into mobile channels, and to achieve efficient use of space through mobile frames. Compared with traditional shelves, the storage density of compact shelving is significantly improved, which can save space and reduce operating costs. The core components of compact shelving include track systems, chassis, transmission devices, frames, panels and door panels, anti-fall devices and sealing devices, etc. Compact shelving has the advantages of high-density storage, safety and reliability, and flexible operation, so it is widely used in archive management, libraries, corporate document rooms and other material storage fields. The production process of compact shelving includes: material preparation, material cutting, forming processing, welding processing, surface treatment, assembly and debugging, finished product packaging and delivery, etc. Among them, material cutting It is used for cutting and punching raw materials, so as to complete the processing of size and connection holes, which is convenient for subsequent operation and assembly. The existing cutting and punching methods mostly use laser cutting to cut and punch materials. However, in order to be able to receive materials without affecting laser cutting during use, the existing processing and punching devices mostly have thorn-like protrusions on the bottom. However, this method will leave scratches on the surface of the material during actual operation, and the cutting positions of compact shelving of different sizes are different, so the bottom thorn-like protrusions will still be laser cut. Therefore, the bottom receiving component needs to be replaced, which is inconvenient for users to use for a long time.

Since the lower end surface of the friction pad 4010 is lower than the lower end surface of the rubber pad 405 installed on the pressing rod 404, the friction pad 4010 is in contact with the external steel plate. At the same time, under the action of the spring 4014, the lifting rod 4012 is pushed up, so that the external steel plate is supported by the ball 4013.
