Description

Technical Field

[0001] This utility model relates to the field of metal pipe processing technology, specifically to an automatic deburring device for stainless steel pipes. Background Technology

[0002] Stainless steel pipes are hollow pipes made of stainless steel. Due to their excellent properties such as corrosion resistance, high strength, and high toughness, they are widely used in petrochemical, medical device, food processing, and building decoration fields. After cutting, sharp burrs, flash, and sharp edges will be generated on the end face. These defects can not only scratch the sealing elements or operators during subsequent installation, affecting the safety and sealing of the connection, but also reduce the aesthetics and quality level of the product. Therefore, they must be removed through a grinding process to obtain a smooth and flat end face that meets the usage requirements and safety standards.

[0003] Currently, deburring of stainless steel pipes mostly relies on manual fixing of the steel pipes, which is labor-intensive and inefficient. Deburring often adopts a single-end operation method, that is, processing one end first, and then turning it around and clamping it to process the other end. This method has low production efficiency, high labor intensity, and it is difficult to ensure that the reference is consistent between the two clamping, which can easily lead to inconsistent processing results at both ends of the steel pipe, affecting product quality. In addition, for the clamping and positioning of long pipes, there are generally problems such as cumbersome alignment and difficulty in aligning the center line.

[0004] Therefore, there is an urgent need for a high-efficiency device that can automatically center and simultaneously process both ends of the steel pipe to improve processing efficiency. Utility Model Content

[0020] In use, the stainless steel tube is first placed inside the V-groove 3 of the support bar 2. Since the grinding wheel 1208 of the grinding assembly 12 and the V-groove 3 are on the same straight line, it can be ensured that the stainless steel tube and the grinding wheel 1208 are on the same straight line. Then, the double-acting screw 10 is driven by the motor 11, and the nut 1202 can convert the rotational motion of the double-acting screw 10 into the linear motion of the slide table 1201.

The baffle 1205 can block the grinding waste and prevent the waste from splashing into the protective cover 9. After the burrs on the stainless steel pipe are removed, the pressure plate 1304 is lifted by cylinder 2 1303, and then the two grinding components 12 are driven to move in opposite directions by the double-acting screw 10, so that the grinding wheel 1208 is separated from the stainless steel pipe and the stainless steel pipe can be removed. When it is necessary to process stainless steel pipes of different diameters, the extension and retraction of the telescopic rod of cylinder 1 4 can drive the support bar 2 to rise and fall, thereby adjusting the height of the support bar 2. The guide rod 7 can guide the support bar 2 and prevent the support bar 2 from tilting. After the height of the support bar 2 is adjusted, it is suitable for use with stainless steel pipes of different diameters. After the height of the support bar 2 is adjusted, cylinder 2 1303 can control the rise and fall of the rubber pressure head 1305, which can adjust the clamping height of the stainless steel pipe.
