The grinding equipment can accurately remove these burrs and burrs through high-speed rotating grinding tools, making the edges of stainless steel pipes smoother and flatter, and can realize machine tool combined processing technology for stainless steel pipes.

[0003] In the existing public documents, the patent announcement number CN208342208U discloses an internal and external drawing precision stainless steel pipe edge material grinding equipment, which is equipped with a lubricating oil cylinder to replenish lubricating oil to the cutting component in time; a grinding machine box to grind away the excess burrs on the edge of the steel pipe; a processing station to enable the steel pipe to be independently processed in different forms during the processing; and a waste collection box to collect waste generated during the steel pipe processing, reducing the labor intensity of manual cleaning. However, this technology still has the following problems.

[0004] In the intelligent manufacturing equipment industry, during the internal and external drawing process of stainless steel pipes, due to the different internal and external drawing intervals of stainless steel pipes, this leads to the fact that in the process of internal and external drawing, the drawing size is adjusted first, and then the burr grinding is adjusted according to the drawing size. It is difficult to perform intelligent and precise adjustment according to the specified drawing size of the stainless steel pipe, and it is difficult to achieve intelligent and precise adjustment of burr grinding at the same time. This not only leads to low efficiency of synchronous adjustment of internal and external drawing and burr grinding, but also poor accuracy of synchronous adjustment of combined processing of stainless steel pipes.

[0041] The working principle of the equipment for grinding the burrs of the stainless steel pipe for drawing inside and outside the present invention is as follows:

[0042] Step 1: During installation, the stainless steel pipe 19 is moved, and the stainless steel pipe 19 drives the workpiece seat 20 to move, and the workpiece seat 20 is plugged into the outer wall of multiple positioning rotating rods 21. The multiple positioning rotating rods 21 can realize the positioning and plugging of the workpiece seat 20, and the position of the stainless steel pipe 19 can be positioned and installed.

[0043] Step 2: During the combined synchronous intelligent precision adjustment processing, the clearance values ​​of drawing and grinding are set on the controller 31, so as to start the adjustment motor 14 through the controller 31, and the adjustment motor 14 drives the linkage screw 3 to rotate, the linkage screw 3 drives the rotating rod 15, and the rotating rod 15 drives another linkage screw 3 to rotate synchronously. The support plate 13 is supported by the combined processing table 1, and the support plate 13 supports the two guide frames 2, thereby increasing the stability of the two guide frames 2. In this way, it is ensured that the two linkage screws 3 can stably rotate in the two guide frames 2. The first sleeve block 4 and the second sleeve block 5 are driven by the linkage screw 3 to approach each other under the action of the thread transmission force, and the inner drawing strip 6 and the outer drawing strip 7 are driven to approach each other, and the inner drawing strip 6 drives the inner drawing die 10 to approach the outer drawing die 8, and the outer drawing strip 7 drives the outer drawing die 8 to approach the inner drawing die 10, and the inner drawing die 10 drives the polished inner strip 11 to approach the outer drawing die 8, and the outer drawing die 8 drives the polished outer strip 9 to approach the inner drawing die 10, and the distance between the outer drawing die 8 and the inner drawing die 10 is reduced, and the distance between the polished inner strip 11 and the polished outer strip 9 is reduced. The distance sensor 32 is used to sense the distance between the distance sensor 32 and the induction block 12. When the distance value sensed by the distance sensor 32 is the same as the gap value set on the controller 31 for drawing and grinding, the controller 31 is used to turn off the rotating motor 23. In this way, the stainless steel pipe 19 can be intelligently and accurately adjusted for internal and external drawing, and the burr grinding of the stainless steel pipe 19 can be intelligently and accurately adjusted at the same time.

[0044] Step 3, during positioning transmission processing, the electric cylinder 25 is started through the controller 31, the electric cylinder 25 pushes the bottom guide bar 26 to move, the bottom guide bar 26 pushes the socket slide 24 to move right, the socket slide 24 moves right synchronously along the combined processing table 1, the socket slide 24 drives the rotating motor 23 to move right, the rotating motor 23 makes the turntable 22 move right, and at the same time the turntable 22 drives multiple positioning rotating rods 21 to move right synchronously.

[0045] The multiple positioning rotating rods 21 drive the workpiece seat 20 to move rightward, and the workpiece seat 20 causes the stainless steel tube 19 to move rightward, and the stainless steel tube 19 begins to move along the chamfered surfaces of the inner drawing die 10 and the outer drawing die 8. At the same time, the controller 31 starts the rotating motor 23 to drive the turntable 22 to rotate, and the turntable 22 drives the multiple positioning rotating rods 21 to rotate, and the multiple positioning rotating rods 21 drive the workpiece seat 20 to rotate, and the workpiece seat 20 drives the stainless steel tube 19 to rotate, and the stainless steel tube 19 rotates and enters along the drawing gap between the outer drawing die 8 and the inner drawing die 10. At the same time, the resistance heating inner strip 17 heats the inner drawing die 10, and the resistance heating outer strip 16 heats the outer drawing die 8, so that the stainless steel tube 19 can be heated to quickly perform internal and external drawing deformation, so that the stainless steel tube 19 can be quickly drawn in the internal and external drawing gap between the inner drawing die 10 and the outer drawing die 8. At the same time, the inner wall of the stainless steel tube 19 is in rotational contact with the outer wall of the inner grinding strip 11 to realize the grinding operation, and at the same time, the outer wall of the stainless steel tube 19 is in rotational contact with the outer grinding strip 9 to realize the grinding operation. In this way, the inner and outer drawing of the stainless steel tube 19 can be synchronously intelligently and precisely adjusted, and the inner and outer grinding of the stainless steel tube 19 can be synchronously intelligently and precisely adjusted.

[0046] Step 4: During the guided rotation, the sleeve block 30 is supported by the combined processing table 1, and the sleeve block 30 provides a stable supporting force for the support bar 29. The support bar 29 supports the arc-shaped support bar 28, and the arc-shaped support bar 28 supports two side guide bars 27. The side guide bar 27 can guide the rotation of one side of the outer wall of the workpiece seat 20, and at the same time, another side guide bar 27 can guide the rotation of the other side of the outer wall of the workpiece seat 20. At the same time, the arc-shaped support bar 28 supports the bottom guide bar 26, and the bottom guide bar 26 guides the bottom end of the outer wall of the workpiece seat 20. It can ensure that the workpiece seat 20 can be guided and rotated by the two side guide bars 27 and the bottom guide bar 26 during the rotation and movement of the workpiece seat 20. Ensure that the workpiece seat 20 is synchronously ground inside and outside while being pulled inside and outside, and stably realize the guided processing, and the processing is more accurate and stable.
