A Processing Technology of Oil Hydraulic Jack Rolling to Remove the Fast Port of Pump Core

Abstract

The invention discloses a processing technology for removing the fast opening of a pump core by rolling with an oil pressure jack, which specifically includes the following steps: S1, blanking a sheet material to form a pump core, and extruding and forming an annular notch at the end of the pump core; S2. Insert the pump core into the tooling fixture of the machine tool, and the annular notch is located on the outside of the tooling fixture; S3. Take two rolling knives and align them with the inner walls on both sides of the same annular notch, and press the two rolling tools The tools are synchronously fed to the inside of the annular notch, the tooling fixture drives the pump core to rotate, and the two rolling knives roll and grind the inner walls on both sides of the annular notch at the same time. The invention improves the grinding efficiency of the pump core annular notch. integrity.

Description

Technical field: [0001] The invention relates to the technical field of production of an oil pressure jack, in particular to a processing technology for removing the quick opening of a pump core by rolling the oil pressure jack. Background technique: [0002] Jacks are generally divided into vertical jacks and horizontal jacks. There are many parts on the jack to meet the work. For the horizontal jack, the pump core is a very critical part in the horizontal jack. When the jack is working, Usually, the oiling work is carried out by ejecting the pump core, and the sealing of the pump core is particularly important during the ejection process of the pump core. [0003] In the prior art, in order to ensure the tightness of the pump core, a sealing ring is usually added to the annular notch at the end of the pump core. It is easy to scratch the sealing ring, which will lead to a decrease in the sealing performance of the sealing ring and affect the oiling work of the pump core. ...

[0003] In the prior art, in order to ensure the tightness of the pump core, a sealing ring is usually added to the annular notch at the end of the pump core. It is easy to scratch the sealing ring, which will lead to a decrease in the sealing performance of the sealing ring and affect the oiling work of the pump core. In view of this, many companies use rolling tools to grind the inside of the annular notch to achieve the purpose of removing the fast mouth. However , during the internal grinding process of the rolling tool in the annular notch, the inner wall of the annular notch will be worn to a certain extent, resulting in a certain gap between the rolling tool and the inner wall of the annular notch, which will cause the rolling tool to be very It is difficult to take into account the two inner walls of the annular notch at the same time, which affects the grinding effect of the rolling tool on the annular notch. Secondly, after the inner wall of the annular notch is finished, it is necessary to grind the end of the annular notch at a right angle Obtuse angle, slow processing efficiency
