Improved straightening machine

Abstract

The invention relates to an improved straightening machine, comprising a base, a sliding platform, a lower template, an upper template and a hydraulic oil cylinder; the base is provided with a pair of guide rails; the sliding platform is embedded between the guide rails; the upper part of the sliding platform is provided with the lower template; the lower template is provided with a cam shaft contacted with the upper template; the upper template is fixedly arranged on the beam of a gantry frame; the gantry frame is fixed on the base; the sliding platform is connected with the hydraulic oil cylinder by using a central shaft fixedly arranged at one end of the base; the hydraulic oil cylinder is connected with an oil tank by using a pipeline; the outlet of the oil tank is connected with the inlet of the oil tank; the oil return port of an oil path is connected with the inlet of an oil-temperature reducing device; the outlet of the oil-temperature reducing device is connected with the inlet of the oil tank. The improved straightening machine has the advantages that: the oil-temperature reducing device can be used for reducing the high oil-temperature in the straightening machine and prevents an electromagnetic valve from being damaged; the working pressure is guaranteed and the working efficiency is improved.

Description

technical field [0001] The present invention relates to an improved straightening machine. Background technique [0002] When the traditional straightening machine is working, it has high toughness and wear resistance to the camshaft. The operation of the straightening process is complicated, and it is responsible for driving the opening and closing of the valve. Due to the long and repeated straightening time, the oil temperature in the straightening machine is high, which can reach more than 85 degrees, which may cause damage to the solenoid valve, resulting in failure to achieve the required pressure, affecting production and reducing work efficiency. Therefore, it is necessary to provide a new technical solutions to address the above deficiencies. Contents of the invention [0003] The purpose of the present invention is to provide an improved straightening machine which prevents the oil temperature from being too high, ensures the working pressure and has high effici...
