Description

Technical Field

[0001] This utility model relates to the field of shearing machine technology, specifically to a sheet metal conveying device for a metal shearing machine. Background Technology

[0002] A shearing machine is a machine that uses one blade to reciprocate linearly relative to another blade to shear sheet metal. It utilizes a moving upper blade and a fixed lower blade, with a suitable blade gap, to apply shearing force to metal sheets of various thicknesses, causing the sheet metal to break and separate to the required dimensions. Shearing machines belong to the category of forging and pressing machinery, primarily used in the metal processing industry. The products are widely used in aerospace, light industry, metallurgy, chemical industry, construction, shipbuilding, automotive, power, electrical appliances, decoration, and other industries, providing the necessary specialized machinery and complete sets of equipment.

[0003] After shearing the sheet metal, most shearing machines use conveyor belts to transport the sheet metal. Due to the different specifications of shearing machines, the cutting height is also different, requiring the use of conveyor belts of different heights for conveying the sheet metal. The subsequent receiving mechanism also needs to be adapted according to the height of the conveyor, which affects the design of the entire production line. Non-standard customization is required based on the conveyor, resulting in high operating costs.

[0004] Therefore, it is of great significance to provide a sheet metal conveying device for a metal shearing machine that can solve the problems existing in the prior art. Utility Model Content

[0005] In view of this, the purpose of this application is to provide a sheet metal conveying device for a metal shearing machine to solve the problem.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

A third rotating roller and a fourth rotating roller are rotatably connected to the two sides of the top of the base frame, and the third rotating roller and the fourth rotating roller are connected by a main conveyor belt.

[0008] A secondary cross frame is hinged to one end of the main cross frame near the third rotating roller. The secondary cross frame is rotatably connected to the main cross frame via a rotating sleeve. A first rotating roller and a second rotating roller are rotatably connected to both ends of the secondary cross frame, and the first rotating roller and the second rotating roller are connected by a swing conveyor belt.
