Punching and flanging integrated machine for rectangular pipes

Abstract

The invention discloses a punching and flanging integrated machine for rectangular pipes. The machine comprises a rack; a punching main machine capable of realizing punching from top to bottom or frombottom to top; a punching lifting support platform for placing and lifting the rectangular pipes to selecting the upper plate parts or the lower plate parts of the rectangular pipes to be punched; aflanging main machine for flanging the upper plate parts or the lower plate parts of the rectangular pipes; a flanging feeding platform which is used for clamping the rectangular pipes on the platformand feeding to ensure that the ends of the rectangular pipes are matched with the flanging main machine for flanging; a 90-degree flipping device comprising a flipping support platform which is fixedon the rack and located at a flipping station, wherein a 90-degree flipping mechanism for clamping the rectangular pipes to rotate by 90 degrees is arranged at one end of the flipping support platform; a first manipulator; and a second manipulator. The punching and flanging integrated machine has the advantages that the punching of two opposite plate parts at the ends of the rectangular pipes andthe flanging of the other two opposite plate parts can be completed, so that the automation of punching and flanging is realized and the processing accuracy and the processing efficiency are increased.

Description

technical field [0001] The invention relates to an integrated machine for punching and folding, in particular to an integrated machine for punching and folding rectangular tubes. Background technique [0002] Rectangular tube (square tube) is a commonly used profile. At present, the cold processing of rectangular tube mainly includes sawing, punching and folding. However, the current cold processing is a discrete process. First, it is cut into a specified length by a sawing machine. The rectangular pipe section, and then move the rectangular pipe section to the punching machine for punching. The punching method is generally from top to bottom. The rectangular pipe sections after punching are collected and sent to the hemming place for hemming. The hemming method adopts punching from top to bottom to make the end of the pipe be hemmed. [0003] However, the rectangular tube used for the body of the car needs to punch holes at the ends of two opposite plate parts of the recta...

Problems solved by technology

[0003] However, the rectangular tube used for the body of the car needs to punch holes at the ends of two opposite plate parts of the rectangular tube, and fold the ends of the other two opposite plate parts. At present, there is no automatic equipment that can complete the above processing. The processing is very cumbersome. It is necessary to punch once on the punching machine and then change the position of the rectangular tube before punching. Similarly, it is also necessary to fold the edge twice on the edge folding machine. When folding the edge, the position of the rectangular tube needs to be adjusted. The operation is very Complicated and inefficient, and because the position of the rectangular tube is adjusted, the position may change every time the edge is folded or punched, which makes it difficult to guarantee the consistency of punching or edge folding on the same rectangular tube
