The invention discloses an upper and lower mold changing device for a pipe bending machine, which comprises a box body, and the two sides of the box body are respectively provided with a movable pipe bending mold and a fixed pipe bending mold, and the movable pipe bending mold and the fixed pipe bending mold are arranged oppositely. The pipe bending fixed die is composed of a pipe bending upper die and a pipe bending lower die. Type structure, the head is fixedly welded on the sliding seat, the sliding seat is slidably connected to the frame, the frame is fixedly installed inside the box and the upper and lower ends are respectively connected to the inner walls of the upper and lower sides of the box, the frame is a rectangular structure and Vertical slide rails are installed on the inner side of the front and rear ends of the frame. The invention realizes the positioning of the sliding seat by setting the cushion seat, avoiding the sinking of the head when the elbow upper mold and the elbow lower mold are replaced, and setting the mobile seat at the same time. The vibration received by the sliding seat is greatly reduced, thereby improving the stability of the rack.
Description
technical field [0001] The invention belongs to the technical field of pipe bending machines, in particular to an upper and lower die changing device for pipe bending machines. Background technique [0002] The upper head of the pipe bending machine is equipped with a pipe bending upper die and a pipe bending lower die, both of which are assembled on the pipe head. When the two are replaced, the head will easily sink. The mold changing device cannot ensure that the head will not sink when the pipe bending upper mold and the pipe bending lower mold are replaced, and the precise position of the pipe bending upper mold and the pipe bending lower mold cannot be guaranteed according to the actual situation. , the vibration of the machine head will cause it to move and affect the bending operation. Contents of the invention [0003] The object of the present invention is to provide an up and down mold change device for pipe benders in order to solve the above problems, which so...
