Description

Technical Field

[0001] The present invention relates to the technical field of intelligent combined processing of stainless steel pipes, and more particularly to a device for grinding burrs of internally and externally drawn stainless steel pipes. Background Art

[0002] In the intelligent manufacturing equipment industry, equipment for grinding the burrs of stainless steel pipes used in combined internal and external drawing processes primarily improves processing quality. By removing burrs, the edges of stainless steel pipes, which are prone to burrs and rough edges during the internal and external drawing process, can be precisely removed using high-speed rotating grinding tools, resulting in smoother, flatter edges and enabling combined machine tool processing of stainless steel pipes.

[0003] Patent publication number CN208342208U discloses a device for grinding edge material for precision stainless steel pipes used for internal and external drawing. This technology features a lubricating oil cylinder to replenish lubricant to the cutting assembly; a grinding chassis to remove excess burrs from the pipe edges; processing stations to enable independent processing of different types of pipes during processing; and a waste collection box to collect waste generated during 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 interval sizes of stainless steel pipes, this leads to the need to first adjust the drawing size and then adjust the burr grinding 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. Therefore, a burr grinding device for edge material of internal and external drawing stainless steel pipes is needed. Summary of the Invention

[0006] The inner wall of the drawn outer strip is fixedly connected to a drawing outer die, and the inner wall of the drawn outer die is fixedly connected to a polished outer strip.

One side of the drawing inner die is chamfered, and one side of the drawing outer die is chamfered. The distance sensor is electrically connected to a controller.

[0007] Preferably, a sensing block is provided on one side of the distance sensor, the sensing block being fixedly connected to the first sleeve block.

The interlocking screw drives the first and second sleeve blocks toward each other under the action of the threaded force, bringing the inner and outer drawing strips closer together. The outer drawing strip drives the outer drawing die toward the inner drawing die, which in turn drives the polished outer strip toward the inner drawing die. The distance between the outer and inner drawing dies decreases, and the distance between the polished inner and outer strips decreases.

[0011] The positioning transmission processing assembly includes a plurality of positioning rotating rods inserted into the inner wall of the workpiece seat, a turntable is installed at one end of the positioning rotating rod, and the plurality of positioning rotating rods are fixedly connected to the turntable.

[0012] A rotary motor is mounted on one end of the turntable. The motor is electrically connected to a controller, and the motor's output is fixedly connected to the turntable.

A curved support bar supports the bottom guide bar, which guides and rotates the workpiece base's outer wall. The two side guide bars and the bottom guide bar guide and rotate the workpiece base.

The rotating motor drives the turntable to rotate, and the workpiece seat drives the stainless steel pipe to rotate. The stainless steel pipe can be quickly drawn in the inner and outer drawing gaps between the drawing inner die and the drawing outer die. At the same time, the inner wall of the stainless steel pipe is in rotational contact with the outer wall of the polished inner bar to realize the grinding operation, which not only greatly improves the efficiency of the synchronous adjustment of the combined processing of the stainless steel pipe, but also greatly improves the accuracy of the synchronous adjustment of the combined processing of the stainless steel pipe.

[0019] 3. The present invention uses a guide rotation component, and the sleeve block provides stable supporting force for the support bar. The arc-shaped support bar supports two side guide bars.

A sleeve slide 24 is fixedly mounted on the outer wall of the rotary motor 23, and the sleeve slide 24 is slidably connected to the combined processing table 1. An electric cylinder 25 is mounted on the side of the sleeve slide 24 and is fixedly connected to the combined processing table 1.

The vertical cross-section of each positioning rod 21 is circular, and the outer wall of the positioning rod 21 is smooth.

[0039] In this embodiment, as shown in the attached Figure 7 - Attachment Figure 9 As shown, a guide rotation assembly is installed on the inner wall of the socket slide 24; the guide rotation assembly includes a bottom guide bar 26 slidably installed inside the socket slide 24, and two side guide bars 27 are provided above the bottom guide bar 26, and the two side guide bars 27 are both slidably connected to the workpiece seat 20, and the bottom guide bar 26 is slidably connected to the workpiece seat 20; an arc-shaped support bar 28 is fixedly installed on one end of the bottom guide bar 26, and the two side guide bars 27 are both fixedly connected to the arc-shaped support bar 28, and the outer wall of the arc-shaped support bar 28 is fixedly connected to a support bar 29.

[0040] A sleeve block 30 is fixedly attached to the outer wall of the support bar 29 and is fixedly connected to the modular processing table 1. A controller 31 is embedded in the side of the modular processing table 1. The two side guide bars 27 are symmetrically arranged about the workpiece base 20. The outer walls of both side guide bars 27 are smooth, and the outer wall of the bottom guide bar 26 is also smooth. The vertical cross-section of the curved support bar 28 is an arc, and the support bar 29 is used to support the curved support bar 28.

[0041] The working principle of the equipment for grinding the burrs of the internal and external drawn stainless steel pipe is as follows:

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

[0043] Step 2: Combined Synchronous Intelligent Precision Adjustment During machining, the gap values ​​for drawing and grinding are set on controller 31, which activates adjustment motor 14. Adjustment motor 14 drives linkage screw 3 to rotate, which in turn drives rotating rod 15, which in turn drives another linkage screw 3 to rotate synchronously. The combined machining table 1 supports support plate 13, which in turn supports the two guide frames 2, increasing the stability of the two guide frames 2. This ensures that the two linkage screws 3 can rotate stably within the two guide frames 2. The interlocking screw 3 drives the first sleeve block 4 and the second sleeve block 5 toward each other under the action of the thread transmission force, and the inner drawing strip 6 and the outer drawing strip 7 approach each other. The inner drawing strip 6 drives the inner drawing die 10 toward the outer drawing die 8, and the outer drawing strip 7 drives the outer drawing die 8 toward the inner drawing die 10. The inner drawing die 10 drives the polished inner strip 11 toward the outer drawing die 8, and the outer drawing die 8 drives the polished outer strip 9 toward the inner drawing die 10. The distance between the outer drawing die 8 and the inner drawing die 10 decreases, and the distance between the polished inner strip 11 and the polished outer strip 9 decreases. The distance sensor 32 senses the distance between the distance sensor 32 and the sensing block 12. When the distance value sensed by the distance sensor 32 is the same as the drawing and grinding gap value set on the controller 31, the controller 31 turns off the rotating motor 23. In this way, the stainless steel pipe 19 can be intelligently and precisely adjusted for internal and external drawing while simultaneously performing intelligent and precise adjustment for burr grinding on the stainless steel pipe 19.

[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 rods 21 to move right synchronously.

[0045] The multiple positioning rods 21 drive the workpiece holder 20 to move rightward, and the workpiece holder 20 causes the stainless steel tube 19 to move rightward, and the stainless steel tube 19 begins to be guided along the chamfered surfaces of the inner drawing die 10 and the outer drawing die 8. At the same time, the controller 31 activates the rotary motor 23 to drive the turntable 22 to rotate, and the turntable 22 drives the multiple positioning rods 21 to rotate, and the multiple positioning rods 21 drive the workpiece holder 20 to rotate, and the workpiece holder 20 drives the stainless steel tube 19 to rotate, and the stainless steel tube 19 rotates along the drawing gap between the outer drawing die 8 and the inner drawing die 10 to enter. 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. In this way, the stainless steel tube 19 can be heated and quickly deformed by drawing inward and outward, so that the stainless steel tube 19 can be quickly drawn in the inner and outer 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 achieve 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 achieve 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 operations 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. The sleeve block 30 provides stable support 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 the 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, while the other 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 process. It ensures that the workpiece seat 20 is synchronously ground inside and outside while being pulled inside and outside, and the guided processing is stably achieved, and the processing is more accurate and stable.
