Problems solved by technology
[0002] During the production process of the pipe expander machine, due to the large wall thickness of the workpiece, the punch often breaks when expanding the pipe, and the broken punch will stay in the mold cavity inside the expanded pipe. If the equipment fails to detect the shutdown in time, The second punch continues to advance and expand the tube, so that the mold cavity is easily scrapped
And if the expansion equipment is damaged, its maintenance is difficult and costly

The invention belongs to the technical field of machining tools of a pipe-expanding machine, and in particular relates to a fracture detecting device for a machining punch of a pipe-expanding machine. The invention discloses a fracture detecting device for the machining punch of the pipe-expanding machine. The fracture detecting device comprises a frame, wherein the frame is movably connected with a punch fixed seat; a punch is arranged on the punch fixed seat; a pipe-expanding internal mold corresponding to the punch is arranged on the frame; a punch detecting sensor is arranged on one side of the pipe-expanding internal mold positioned facing to the punch; a fixed seat positioning sensor is arranged on the frame; the vertical distance between the fixed seat positioning sensor and the punch detecting sensor is the same as the length of the punch; and the fixed seat positioning sensor and the punch detecting sensor are connected with an alarm controller. The device can well detect whether the punch fractures or not, so that the device is prevented from being damaged, early warning for the fracture of the punch can be automatically carried out, and the time and cost are saved.
Description
technical field [0001] The invention belongs to the technical field of processing tools for pipe expanding machines, and in particular relates to a break detection device for processing punches of pipe expanding machines. Background technique [0002] During the production process of the pipe expander machine, due to the large wall thickness of the workpiece, the punch often breaks when expanding the pipe, and the broken punch will stay in the mold cavity inside the expanded pipe. If the equipment fails to detect the shutdown in time, The second punch continues to advance and expand the pipe, so that the mold cavity is very easy to scrap. And if the expansion equipment is damaged, its maintenance is difficult and expensive. Contents of the invention [0003] The purpose of the present invention is to solve the technical problems described above, and to provide a device for detecting the breakage of punches in pipe expanding machining, the technical solution of which is as...
