Punching device for bridge plate production line

Abstract

The invention relates to a punching device for bridge plate production line. The punching device is characterized in that the punching device consisting of a square frame body, an II# upper connecting plate, a core plate, an inserting plate, a cylinder, a stripper plate, a cavity plate, a cavity bottom plate and a liner plate is installed in a transition bracket between the upper operating platform and the lower operating platform of a press, and a lower plate in the square frame body is arranged on the liner plate; the bottom surface of an I# upper connecting plate is connected with the II# upper connecting plate, and the core plate of a core die set is arranged on the bottom surface of the II# upper connecting plate; a pressing plate, the stripper plate and the cavity plate are installed on the bottom surface of the core plate in sequence; the inserting plate driven through the cylinder is installed in the core plate between core plate and the II# upper connecting plate. The punching device has the advantages that the design is reasonable, the structure is compact, not only punching and flanging can be simultaneously realized, but also the punched hole has accurate position, theproduction efficiency is high, the product quality is good, the labor intensity is low, the operation is safe, and the use is very convenient.

Description

technical field [0001] The invention belongs to equipment for manufacturing bridge plates in engineering construction, in particular to a punching device suitable for a bridge plate production line in the bridge plate production line. It is also suitable for guardrail products that need to be turned over after punching holes. Background technique [0002] As we all know, bridge plates are widely used in engineering construction, and bridge plates are connected or assembled using connecting holes. According to the construction needs of the project, use the connection process holes, connectors, and keels to connect and assemble the bridge plates into a vertical or horizontal space with a certain height, length, and width. Such holes are usually called connection holes. The number of connection holes on the bridge plate is small, and they are generally distributed around the periphery of the bridge plate. Therefore, strict position requirements are required for the connection ...

Problems solved by technology

The efficiency of such a production process is very low. At the same time, due to the secondary punching, the second alignment is very difficult, and most of the punching molds used now often have no blanking during blanking, and the scraps that are washed out If it is left on the workbench, it is extremely easy to cause waste, and the bridge plate has to be scrapped, which brings economic losses to the manufacturing unit
