Description

Technical Field

[0001] The present invention relates to the technical field of cold rolling equipment, in particular to a cold rolling device for producing stainless steel. Background Art

[0002] In the field of stainless steel strip processing, cold rolling mills are often used to repeatedly press stainless steel sheets to form products that meet the requirements. In particular, in the production and processing of stainless steel strips, thicker stainless steel sheets are pressed into thinner stainless steel strips through cold rolling mills.

[0003] For example, a cold rolling device for stainless steel production with announcement number CN213316823U includes a base plate, a hydraulic support seat, a guide roller and a pressure sensor. The hydraulic support seat is provided at the upper end of the base plate, and the hydraulic support seat is connected to the base plate by bolts. A mounting frame is provided at the upper end of the hydraulic support seat, and the mounting frame is connected to the hydraulic support seat by bolts. By arranging the hydraulic sensor, the hydraulic support seat and the display screen, during the operation of the device, the pressure sensor can detect the pressure of the steel strip on the guide roller and display it on the display screen, thereby facilitating the staff to understand the surface tension of the steel strip and adjust the height of the guide roller through the hydraulic support seat. To achieve the adjustment of the surface tension of the steel strip, avoid the steel strip from being torn during the cold rolling process, ensure the performance of the steel strip, improve the practicality of the device and the cold rolling effect. However, when the stainless steel material is cold rolled, due to insufficient lubrication, quality defects such as scratches and oxidation spots will appear on the surface of the steel strip. If the lubricating oil is directly sprayed by a nozzle, uneven lubrication may occur. Uneven lubrication will lead to uneven oil film thickness, which cannot effectively isolate the direct contact between the air and the surface of the stainless steel material, resulting in the formation of oxide scale on the stainless steel surface, reducing the quality of cold rolling processing. In order to reduce the impact of residual lubricating oil on the surface of the stainless steel strip after rolling, the residual lubricating oil needs to be recovered and processed.

[0004] Therefore a cold rolling device for stainless steel production is proposed to solve the above-mentioned problems. Summary of the Invention

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] 1. By setting up the lubrication assembly, the operator connects the interface end of the water pipe to the external pressurized lubricating oil pipeline. The pressurized lubricating oil is sprayed out through the nozzle, and the stainless steel coil passes through the position between the two squeezing rollers. The motor 2 and the motor 1 are started to work. The motor 2 drives the upper squeezing roller to rotate. The upper squeezing roller can drive the lower squeezing roller to rotate through the belt. The rotation of the motor 1 drives the rotating rod, the reciprocating screw and the center rod to rotate. The rotation of the reciprocating screw causes the moving rod to move back and forth in a straight line. The moving rod drives the horizontal bar to move, and the horizontal bar drives the push rod to move. The push rod pushes the nozzle, and the nozzle rotates inside the installation slot. The spring 1 is compressed or stretched to assist the rotation of the nozzle.

The rotation of the nozzle sprays, which improves The lubricating oil spraying range and uniformity are improved. The horizontal bar will also drive the sliding rod to slide inside the limit groove, and the horizontal bar will drive the mounting frame and the horizontal pressure roller to move back and forth in a straight line. The horizontal pressure roller will spread the lubricating oil on the top surface of the stainless steel coil evenly. The lubricating oil sprayed from the nozzle is guided by the guide block to facilitate the diversion and dispersion of the lubricating oil. The excess lubricating oil falls into the collection tank for collection. The moving rod will synchronously drive the vertical rod and the oblique pressure roller to move. The vertical rod drives the horizontal rod to move. The horizontal rod is blocked by the blocking block, which will drive the vertical rod to rotate. The vertical rod acts on the torsion spring to drive the oblique pressure roller to rotate, so that the oblique pressure roller can rotate and spread evenly. The even spreading of the horizontal pressure roller and the oblique pressure roller improves the uniformity of the lubricating oil coating, solves the problems of insufficient lubrication, quality defects on the steel strip surface, and uneven lubrication that will cause oxide scale to form on the stainless steel surface.

[0029] 2. A scraping assembly is provided. The rolled stainless steel coil is output through the extrusion roller and supported by the support plate. At this time, the operator connects the nozzle to the water spray pipe, and high-pressure water is sprayed through the nozzle. The water impacts the top of the stainless steel coil, which is convenient for flushing grease and debris. The grease and debris fall into the collection tank at the bottom. At the same time, the impact of the water will drive the semi-water wheel to rotate, and the semi-water wheel drives the rotating rod and the synchronous pulley to rotate, and the nozzles on both sides spray water intermittently. The semi-water wheels on both sides are symmetrically arranged, so that the nozzle on one side first impacts and drives the semi-water wheel on one side to rotate, and the semi-water wheel on one side drives the rotating rod and the synchronous pulley to rotate. The synchronous pulley on one side drives the synchronous pulley and the rotating rod on the other side through the toothed belt, so that the scraping rods on both sides rotate, and then the nozzle on the other side starts to spray water, and the two rotating rods rotate and reset, so that the scraping rods on both sides rotate back and forth to scrape and clean.
