Abstract

The invention relates to the processing of metals by pressure, in particular to a tool for the pressure treatment of products. The purpose of the invention is to improve the quality of the products and the reliability of the tool by increasing its durability. The pressing tool contains a pressing roller 1 mounted in a fork 3 by means of an axis 2, as well as a lubricant supply unit. The lubricant supply unit is made in the form of a metering unit consisting of a hollow body 9 with diametrically located through holes with a spring-loaded spool 8 placed in its cavity, two tubes, one of which is connected to a source of lubricating fluid, and the other is located near the treatment zone. The batcher also contains a profiled cam rigidly mounted on the axis 2 of the squeezing roller with the possibility of interaction with the slide valve. Improving the durability of the squeezing roller and the quality of the products is achieved due to the fact that the squeezing tool is equipped with a pulsed lubrication supply unit. 1 hp f-ly, 1 ill.

Description

The invention relates to the processing of metals by pressure, in particular to a tool for the pressure treatment of products.

The purpose of the invention is to improve the quality of the products and the reliability of the tool by increasing the resistance "

The drawing shows the instrument, a general view.

The pressing tool contains a pressing roller 1 mounted rotatably on axis 2 in fork 3 of the mount. At the output end of axis 2, a profiled cam 4 is placed, in contact with roller 5. mounted on axis 6 fixed in fork 7 "Last" It is connected with the spool 8, which is placed in the housing 9 and fired with a spring 10. The housing 9 is closed by a cover 11 and supplied with pipes 12 and 13 for supplying lubricants

The pressing tool works as follows

 Upon contact of the crushing roller 1 and the rotating one, it caused the billet to be deformed, the crushing wheel was pressed (it acquires the rotary ji 5x5) which is transmitted to the axis of the cooler 4 "FGS - pressing the roller 5 to the cam by spring 10 and The cam 4 ensures, when the latter is wound, the reciprocating movement of the spool 8 in the housing 9S, the displacement of the spool 8 leads to a coincidence of the through holes in the spool 8 and the housing 9 through which the lubricating fluid under pressure from the systems The machine is driven through the line: pipe 12, body 9, spool 8, tube 13 enters the deformation zone of the headers. The portion of lubricant is provided by the cam 4 profile, when the squeezing roller 1 is retracted

upon completion of the deformation process, its rotation is stopped, and the process of feeding the lubricating fluid is completed and

The use of the proposed device provides reliable pulsating lubrication of the squeezing roller, which significantly reduces the sifting of the deforming roller, thereby increasing the quality of the parts manufactured and the durability of the squeezing roller.
