Offset load correction method for multi-station hydraulic machine

Abstract

The invention belongs to the technical field of unbalance loading correction, and discloses an unbalance loading correction method for a multi-station hydraulic machine, which comprises the following steps: S1, firstly, correspondingly putting a first workpiece, a second workpiece and a third workpiece into a first station, a second station and a third station respectively; and S2, then the stamping device is controlled to drive a first stamping head, a second stamping head and a third stamping head to apply machining pressure to the first workpiece, the second workpiece and the third workpiece below correspondingly. According to the unbalance loading correction method of the multi-station hydraulic machine, correct implementation of the extrusion forming process of the multi-station hydraulic machine is completed in the state that the pressure of each station is balanced, and during actual extrusion production, if the extrusion force of each station is different, the hydraulic oil cylinder is not required to return oil every time; the oil return amount of the hydraulic oil can be judged by observing whether the specific pressure value on the pressure display meter is within a safe range or not, and timely maintenance is facilitated.

Description

technical field [0001] The invention belongs to the technical field of eccentric load correction, in particular to a method for eccentric load correction of a multi-station hydraulic press. Background technique [0002] When single-station hydraulic presses are used for multi-process production of forgings, there are problems of resource waste such as many people, multiple machines, and low efficiency. Multi-station hydraulic presses are new equipment to solve these problems and ensure high-efficiency and continuous production; currently many The station hydraulic press is an important part of the forging automatic production line. During the forging production process of the common multi-station hydraulic press, each station requires different loads and severe eccentric loads; due to the existence of eccentric loads, the hydraulic press slider, body The baffle (guide rail), die and punch are frequently worn, roughened or even broken during use; due to the high frequency of ...

Problems solved by technology

[0002] When single-station hydraulic presses are used for multi-process production of forgings, there are problems of resource waste such as many people, multiple machines, and low efficiency. Multi-station hydraulic presses are new equipment to solve these problems and ensure high-efficiency and continuous production; currently many The station hydraulic press is an important part of the forging automatic production line. During the forging production process of the common multi-station hydraulic press, each station requires different loads and severe eccentric loads; due to the existence of eccentric loads, the hydraulic press slider, body The baffle (guide rail), die and punch are frequently worn, roughened or even broken during use; due to the high frequency of use of multi-station hydraulic presses in the production process, and the complex working conditions, coupled with factors such as eccentric loads, it is easy to cause Inaccurate product positioning leads to unqualified products; among them, the abnormal noise generated during the friction process between the slider of the multi-station hydraulic press and the baffle plate of the fuselage is particularly obvious, which will cause resonance, affect the service life of the multi-station hydraulic press, and reduce product quality

[0003] Existing hydraulic presses do not have the function of eccentric load correction. Multi-station hydraulic presses are used in the production of forging parts. When each station requires different pressures, serious eccentric loads occur. Punch, premature wear, roughening, breakage in use, the cost of the whole part is increased
