Driving device of upper clamp die and lower clamp die of left-right integrated pipe bending machine

Abstract

The invention discloses a driving device of an upper clamp die and an lower clamp die of a left-right integrated pipe bending machine, which has the advantages of simple structure and low cost. The driving device comprises a machine head and a pipe bending arm movably arranged on the machine head, the pipe bending arm is provided with an upper clamp die seat, a lower clamp die seat, a clamp cylinder, an upper connecting rod group and a lower connecting rod group, wherein the upper clamp die seat and the lower clamp die seat respectively correspond to an upper clamp die and a lower clamp die, the upper connecting rod group and the lower connecting rod group respectively correspond to the upper clamp die seat and the lower clamp die seat, the end of the piston rod of the clamp cylinder is movably provided with a connecting rod, and the two ends of the connecting rod are respectively connected with the upper connecting rod group and the lower connecting rod group. The structure of the invention is very simple, the clamp cylinder is respectively connected with the upper connecting rod group and the lower connecting rod group through the connecting rod, thereby realizing the opening and closing motion of the upper clamp die and the lower clamp die and greatly reducing the manufacturing cost.

Description

technical field [0001] The invention relates to a left and right integrated pipe bending machine, in particular to a driving device for an upper and a lower clamping die in the left and right integrated pipe bending machine. Background technique [0002] At present, the left and right integrated pipe bending machines have a machine head that can rotate 180 degrees, and upper and lower wheel molds are respectively installed on the upper and lower ends of the main shaft. The upper and lower clamping molds matched with the mold and the driving device of the upper and lower clamping molds. When in use, the upper wheel mold, upper clamping mold and the driving device of the upper clamping mold can be operated, the pipe can be bent to the left, and the driving device of the lower wheel mold, lower clamping mold and lower clamping mold can be operated by rotating the machine head. Bend the pipe to the right. This kind of pipe bending machine can process some very complicated pipe...
