Abstract

The invention discloses an oil pressure punching machine for U-shaped pipes. The oil pressure punching machine comprises a machine frame, the oil pressure punching machine is characterized in that themachine frame is provided with a pair of axial positioning baffle rings, and a pair of clamping mechanisms are arranged, at one side of the axial positioning baffle rings, on the machine frame; a plurality of punching oil cylinders are arranged, between the axial positioning baffle rings and the clamping mechanisms, on the machine frame; and a control table is arranged on the machine frame, the control table comprises a PLC programmable logic controller, and the clamping mechanisms and the punching oil cylinders are both electrically connected with the PLC programmable logic controller. The oil pressure punching machine for the U-shaped pipes has less error and higher efficiency.

Description

technical field [0001] The invention belongs to the field of special processing equipment, and in particular relates to an oil pressure punching machine for U-shaped pipes. Background technique [0002] A U-shaped tube is usually used as a support component, which consists of two parallel vertical tubes of equal length and a cross tube connecting the ends of the two vertical tubes. Several holes need to be processed along the length direction of the two vertical tubes, and the axial directions of all the holes must be guaranteed to be parallel to the length direction of the horizontal tube. [0003] The processing of these holes in the prior art requires the following steps: (1) The staff inserts one of the vertical pipes into the punching machine, swings the other vertical pipe around the axis of the vertical pipe, and visually or uses a positioning device to make the punching direction coincide with that of the horizontal pipe. (2) The punching machine runs and processes ...
