Description

Technical Field

[0001] The invention relates to the technical field of stainless steel processing mechanical equipment, and in particular to stainless steel surface drawing and polishing equipment. Background Art

[0002] Stainless steel surface brushing technology is the most popular surface treatment technology in the stainless steel industry today. It refers to a surface treatment method that uses a brushed abrasive belt to grind the surface of a stainless steel workpiece to form linear patterns such as straight wire patterns and snowflake patterns, thereby achieving a decorative effect. The brushed surface of the stainless steel can reflect the texture of the metal material, and the matte surface formed after the brushing process makes the workpiece surface more wear-resistant.

[0003] However, when the existing stainless steel surface drawing and polishing equipment is drawing and polishing a conical tube or a special tubular workpiece with features such as grooves and protrusions on the surface, due to the change in the diameter of the workpiece, the ordinary use of a rotating wheel to drive the drawing sandpaper for drawing and polishing is difficult for the hard rotating wheel to drive the drawing sandpaper to contact the surface depressions of the stainless steel tubular workpiece with changed surface size, resulting in a poor drawing effect. There are also methods to adapt to the diameter change of the workpiece surface through intelligent automatic adjustment or manual adjustment, which is costly and prone to errors.

DETAILED DESCRIPTION

[0047] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0048] The present invention provides a stainless steel surface wire drawing and polishing device, which improves the existing stainless steel surface wire drawing and polishing device. When wire drawing and polishing a conical tube or a special tubular workpiece with features such as grooves and protrusions on the surface, due to the change in the diameter of the workpiece, when the conventional wire drawing and polishing device uses a rotating wheel to drive the wire drawing sandpaper for wire drawing and polishing, the hard rotating wheel is not easy to drive the wire drawing sandpaper to contact the surface depression of the stainless steel tubular workpiece with the changed surface size, resulting in poor wire drawing effect. There are also intelligent automatic adjustment or manual adjustment to adapt to the diameter change of the workpiece surface, which is costly and easy to make mistakes.

[0049] The technical solution of the present invention is to improve the above technical problems, and the overall idea is as follows: by utilizing the mutual cooperation between the air pump 4 and the wire drawing and polishing assembly 2, the fluidity of the gas is utilized to enable the wire drawing and polishing assembly 2 to drive the wire drawing sandpaper 1 to better fit the surface of the stainless steel tubular workpiece, and at the same time, the working stability of the air pump 4 and the fixation of the workpiece by the clamping transmission assembly 3 are utilized to ensure the stable contact between the wire drawing sandpaper 1 and the outer surface of the workpiece, so that the wire drawing sandpaper 1 can fit closely to the surface of the stainless steel tubular workpiece whose outer surface size has changed, thereby ensuring the wire drawing effect on the surface of the stainless steel tubular workpiece whose outer surface size has changed;

[0050] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods;

[0051] The present invention provides a stainless steel surface wire drawing and polishing device, comprising wire drawing sandpaper 1, and further comprising:

[0052] A wire drawing and polishing assembly 2, wherein the wire drawing and polishing assembly 2 is arranged outside the wire drawing sandpaper 1, and can drive the wire drawing sandpaper 1 to better fit the outer surface of the stainless steel tubular workpiece whose surface size has changed;

[0053] A clamping and transmission component 3, which is arranged above the wire drawing and polishing component 2 and is used to clamp the workpiece and transmit the workpiece into the wire drawing and polishing component 2;

[0054] An air pump 4, which is arranged on one side of the wire drawing and polishing assembly 2 and is used to provide power for the wire drawing and polishing assembly 2;

[0055] A support assembly 5, wherein the support assembly 5 is arranged outside the wire drawing and polishing assembly 2 and the clamping and transmission assembly 3, and is used to provide a support point for the wire drawing and polishing assembly 2 and the clamping and transmission assembly 3;

[0056] By adopting the above technical scheme, when it is necessary to draw the surface of a stainless steel tubular workpiece whose outer surface size has changed, the staff first holds the stainless steel tubular workpiece whose outer surface size has changed, and places it between the drawing and polishing assembly 2 and the clamping and transmission assembly 3, and then controls the clamping and transmission assembly 3 to clamp the stainless steel tubular workpiece whose surface size has changed from its inner surface, and after the workpiece is fixed, controls the clamping and transmission assembly 3 again to transmit the clamped workpiece to an appropriate position in the drawing and polishing assembly 2, that is, to ensure that the horizontal height of the upper surface of the workpiece is lower than the horizontal height of the upper surface of the drawing sandpaper 1, and then starts the air pump 4, which drives the drawing and polishing assembly 2 to work, and the drawing and polishing assembly 2 drives the drawing sandpaper 1 to fit tightly with the outer surface of the stainless steel tubular workpiece whose surface size has changed, and then controls the clamping and transmission assembly 3 again to drive the stainless steel tubular workpiece whose surface size has changed to rotate, and the rotating workpiece surface rubs against the drawing sandpaper 1, thereby drawing and polishing the outer surface of the stainless steel tubular workpiece with an uneven surface;

[0057] Compared with the existing stainless steel surface drawing and polishing equipment, when drawing and polishing a tapered tube or a special tubular workpiece with features such as grooves and protrusions on the surface, due to the change in the diameter of the workpiece, when the ordinary wheel is used to drive the drawing sandpaper for drawing and polishing, the hard wheel is not easy to drive the drawing sandpaper to contact the surface depression of the stainless steel tubular workpiece with the changed surface size, resulting in poor drawing effect. There are also intelligent automatic adjustment or manual adjustment to adapt to the diameter change of the workpiece surface, which is costly and prone to errors;

[0058] The present invention utilizes the mutual cooperation between the air pump 4 and the wire drawing and polishing assembly 2, and utilizes the fluidity of the gas to enable the wire drawing and polishing assembly 2 to drive the wire drawing sandpaper 1 to better fit the surface of the stainless steel tubular workpiece, and at the same time utilizes the working stability of the air pump 4 and the fixation of the workpiece by the clamping transmission assembly 3 to ensure the stable contact between the wire drawing sandpaper 1 and the outer surface of the workpiece, so that the wire drawing sandpaper 1 can fit closely to the surface of the stainless steel tubular workpiece whose outer surface size has changed, thereby ensuring the wire drawing effect on the surface of the stainless steel tubular workpiece whose outer surface size has changed;

[0059] In addition, by controlling the output of the air pump 4 and cooperating with the clamping and transmission component 3 to tighten the workpiece, the wire drawing and polishing component 2 of the present invention can perform wire drawing and polishing on the surfaces of stainless steel tubular workpieces of different sizes, thereby improving the actual performance of the wire drawing and polishing equipment of the present invention.

[0062] A side plate 52, wherein the side plate 52 is fixedly connected to the upper surface of the base 51;

[0063] A first support plate 53, wherein the first support plate 53 is disposed above the drawing sandpaper 1 and the two ends thereof are not in contact with the side plate 52;

[0064] A second support plate 54, wherein the second support plate 54 is disposed above the first support plate 53 and both ends of the second support plate 54 are slidably connected to the side plate 52;

[0066] The motor 31 is fixedly connected to the second support plate 54;

[0067] A fixed block 32, the upper surface of which is fixedly connected to the rotating shaft of the motor 31;

[0068] A first hydraulic telescopic rod 33, wherein the first hydraulic telescopic rod 33 is disposed between the first support plate 53 and the second support plate 54, and the first hydraulic telescopic rod 33 is fixedly connected to the lower surface of the fixed block 32;

[0069] A second hydraulic telescopic rod 34, the second hydraulic telescopic rod 34 is located on one side of the motor 31, the hydraulic cylinder of the second hydraulic telescopic rod 34 is fixedly connected to the side plate 52, and the telescopic end of the second hydraulic telescopic rod 34 is fixedly connected to the upper surface of the second support plate 54;

[0070] A connecting rod 35, wherein the connecting rod 35 is fixedly connected to the output end of the first hydraulic telescopic rod 33;

[0071] A first mounting rod 36, wherein the first mounting rod 36 is fixedly connected to a side surface of the connecting rod 35;

[0072] Two clamping plates 37, the two clamping plates 37 are symmetrically arranged on both sides of the first mounting rod 36, and the upper parts of the two clamping plates 37 are slidably connected to the first mounting rod 36;

[0073] Two No. 2 mounting rods 38, the two No. 2 mounting rods 38 are symmetrically arranged on the No. 1 support plate 53, the two No. 2 mounting rods 38 are both welded to the No. 1 support plate 53, and the two No. 2 mounting rods 38 are rotatably connected to the middle parts of the two clamping plates 37 respectively;

[0074] An L-shaped connecting rod 39, one end of which is fixedly connected to the hydraulic cylinder of the first hydraulic telescopic rod 33, and one end of which is away from the hydraulic cylinder of the first hydraulic telescopic rod 33 and fixedly connected to the first support plate 53;

[0075] As an embodiment of the present invention, the wire drawing and polishing assembly 2 includes:

[0076] A slide groove 21, wherein the slide groove 21 is provided on the upper surface of the base 51;

[0077] The arc-shaped bracket 22 is arranged below the two clamping plates 37. The lower surface of the arc-shaped bracket 22 is slidably connected to the base 51 through the slide groove 21. The arc-shaped bracket 22 is provided in three or more forms and is circumferentially arranged above the base 51 to form an annular bracket 6.

[0078] The airbag 23 is attached to the inner surface of the arc bracket 22 and is adhesively connected to the inner surface of the arc bracket 22. The side of the airbag 23 away from the arc bracket 22 is fixedly connected to the drawing sandpaper 1;

[0079] An air inlet hole 24, wherein the air inlet hole 24 is provided on the airbag 23;

[0080] By adopting the above technical scheme, when it is necessary to draw the surface of a stainless steel tubular workpiece whose outer surface size has changed, the staff first holds the stainless steel tubular workpiece whose surface size has changed, and places it on the two clamps 37, that is, the tubular workpiece is sleeved on the two clamps 37, and then starts the No. 1 hydraulic telescopic rod 33, the output end of the No. 1 hydraulic telescopic rod 33 extends downward, and the No. 1 hydraulic telescopic rod 33 extends downward to drive the connecting rod 35 welded to its output end to move downward. Since the connecting rod 35 is fixedly connected to the No. 1 mounting rod 36, two clamps 37 are symmetrically arranged on the No. 1 mounting rod 36, the two clamps 37 are slidably connected to the No. 1 mounting rod 36, and the middle parts of the two clamps 37 are connected to the No. 2 mounting rod on the No. 1 support plate 53. The mounting rod 38 is rotatably connected, and the No. 1 support plate 53 is fixedly connected to the hydraulic cylinder of the No. 1 hydraulic telescopic rod 33 through the L-shaped connecting rod 39, so that the distance between the No. 1 support plate 53 and the hydraulic cylinder of the No. 1 hydraulic telescopic rod 33 is constant and they rotate synchronously. At this time, the No. 1 mounting rod 36 slidably connected to the upper ends of the two clamping plates 37 moves downward, while the No. 2 mounting rod 38 rotatably connected in the middle of the two clamping plates 37 is stationary. Therefore, after the two clamping plates 37 are pushed by the No. 1 mounting rod 36, their lower ends open to both sides of the No. 1 mounting rod 36. When the two clamping plates 37 are opened to a certain angle until their sides are in close contact with the inner surface of the tubular workpiece, the output end of the No. 1 hydraulic telescopic rod 33 is controlled to stop extending. At this time, the two clamping plates 37 complete the clamping and fixing of the tubular workpiece.

[0081] The two clamping plates 37 clamp and fix the tubular workpiece by contacting the inner surface of the tubular workpiece at their lower ends, instead of fastening by contacting the clamping plates 37 with the outer surface of the workpiece. The clamping is achieved from the inside of the workpiece, thus avoiding the wire drawing blind area of ​​the wire drawing sandpaper 1 when wire drawing and polishing the outer surface of the workpiece due to the existence of the clamping plates 37.

[0082] After the workpiece is clamped, the No. 2 hydraulic telescopic rod 34 is started, and the output end of the No. 2 hydraulic telescopic rod 34 extends downward. Since the output end of the No. 2 hydraulic telescopic rod 34 is welded to the upper surface of the No. 2 support plate 54, and the No. 2 support plate 54 is slidably connected to the side plate 52, the No. 2 support plate 54 is connected to the No. 1 support plate 53 through the motor 31, the fixing block 32, the No. 1 hydraulic telescopic rod 33, the connecting rod 35, the No. 1 mounting rod 36, the clamping plate 37, the No. 2 mounting rod 38 and the L-shaped connecting rod 39. At this time, the output end of the No. 1 hydraulic telescopic rod 33 is stationary, and the connecting rod 35 , a stable structure is formed between the clamping plate 37 and the workpiece. Therefore, when the No. 2 support plate 54 is pushed downward by the No. 2 hydraulic telescopic rod 34 and drives the No. 1 hydraulic telescopic rod 33 connected thereto to move downward, the clamping plate 37 and the No. 1 hydraulic telescopic rod 33 will not move relative to each other, so that the No. 2 support plate 54 moves downward to drive the clamping plate 37 to move downward, and the clamping plate 37 drives the workpiece to move downward, and the workpiece moves downward into the drawing and polishing assembly 2. When the upper surface of the workpiece is lower than the horizontal height of the upper surface of the drawing sandpaper 1, the output end of the No. 2 hydraulic telescopic rod 34 is controlled to stop moving;

[0083] Furthermore, since the two sides of the No. 1 support plate 53 do not contact the side plate 52, and the No. 1 support plate 53 is fixedly connected to the hydraulic cylinder of the No. 1 hydraulic telescopic rod 33 through the L-shaped connecting rod 39, the distance between the No. 1 hydraulic telescopic rod 33 and the No. 1 support plate 53 is fixed, so when the No. 2 support plate 54 moves downward, the No. 1 support plate 53 and the No. 2 support plate 54 are relatively stationary, ensuring the stable clamping of the clamping plate 37;

[0084] After the workpiece enters the wire drawing and polishing assembly 2, the staff pushes the arc bracket 22, and the arc bracket 22 moves along the slide groove 21 to one end of the slide groove 21 close to the center of the bottom plate, and then the cable tie 12 is used as a limiter to fix multiple arc brackets 22, and at this time, the arc bracket 22 forms a ring bracket 6;

[0085] Then, the air pump 4 is connected to the airbag 23 through the air inlet 24, and the airbag 23 is inflated by the air pump 4, and the airbag 23 gradually expands. Since the arc bracket 22 fixedly connected to one side of the airbag 23 is fixed, the airbag 23 expands toward the side away from the arc bracket 22, and the side of the airbag 23 away from the arc bracket 22 is fixedly connected with the drawing sandpaper 1. Therefore, when the airbag 23 gradually expands, it drives the drawing sandpaper 1 to move toward the side of the workpiece surface, and utilizes the fluidity of the gas and the elasticity of the airbag 23 to enable the airbag 23 to drive the drawing sandpaper 1 to better fit the workpiece surface. When the airbag 23 drives the drawing sandpaper 1 to be in close contact with the workpiece surface, the air pump 4 is controlled to stop supplying air to the airbag 23;

[0086] Then, the motor 31 is started, the rotation shaft of the motor 31 rotates to drive the fixed block 32 connected thereto to rotate, the rotation of the fixed block 32 drives the No. 1 hydraulic telescopic rod 33 to rotate, the rotation of the No. 1 hydraulic telescopic rod 33 drives the connecting rod 35 and the L-shaped connecting rod 39 to rotate, the rotation of the connecting rod 35 drives the clamping plate 37 to rotate, the clamping plate 37 drives the workpiece to rotate, and at the same time the L-shaped connecting rod drives the No. 1 support plate 53 to rotate, friction occurs between the rotating workpiece and the stationary wire drawing sandpaper 1, and the wire drawing polishing of the workpiece surface is completed;

[0087] Therefore, the elasticity of the airbag 23 and the fluidity of the gas drive the wire drawing sandpaper 1 to better fit the surface of the stainless steel tubular workpiece with changed outer surface dimensions, thereby ensuring the wire drawing effect of the wire drawing sandpaper 1 on the stainless steel pipe with uneven surface;

[0088] Furthermore, by setting the thickness of the airbag 23 to be no greater than 2 mm, the phenomenon that the deformation effect of the airbag 23 is deteriorated due to the excessive thickness of the airbag 23 is avoided, thereby ensuring the fit between the drawing sandpaper 1 and the surface of the workpiece;

[0089] At the same time, the staff can control the air intake of the airbag 23 through the air pump 4, and then control the moving distance of the wire drawing sandpaper 1 by controlling the expansion degree of the airbag 23, so that the wire drawing and polishing assembly 2 can be suitable for stainless steel tubular workpieces with different sizes and changing surface dimensions, thereby improving the actual use performance of the wire drawing and polishing equipment.

[0090] As an embodiment of the present invention, the side of the airbag 23 away from the arc-shaped bracket 22 is fixedly connected to the brushed sandpaper 1 through Velcro;

[0091] By adopting the above technical solution, the airbag 23 is arranged to be fixedly connected to the drawing sandpaper 1 through Velcro, so that when the drawing sandpaper 1 is worn out after repeated use, it is convenient to replace the drawing sandpaper 1, thereby further improving the actual performance of the drawing and polishing equipment.

[0092] As an embodiment of the present invention, a silicone layer 7 is fixedly connected to the outer surface of the clamping plate 37;

[0093] By adopting the above technical solution, a silicone layer 7 is fixedly connected to the outer surface of the clamp 37, and the elasticity and deformation of the silicone itself are utilized, and the friction coefficient is large, which increases the friction between the clamp 37 and the workpiece, thereby improving the stability of the clamp 37 in clamping the workpiece.

[0094] As an embodiment of the present invention, the lower half of the arc-shaped bracket 22 is set to be inclined, and a fan 8 is fixedly connected to the rotating shaft of the motor 31 and located above the fixed block 32;

[0095] By adopting the above technical solution, a lot of debris will be generated during the friction between the workpiece surface and the drawing sandpaper 1, so the lower half of the arc bracket 22 is set to be inclined, that is, the upper end diameter of the cylindrical support frame formed by multiple arc brackets 22 is larger than the lower end diameter, so that a part of the debris can slide down along the slope of the arc bracket 22 under the action of its own weight, which is convenient for collecting the debris;

[0096] During the wire drawing process of the workpiece, the rotating shaft of the motor 31 rotates to drive the workpiece to rotate to complete the wire drawing and polishing process, and a fan 8 is fixedly connected to the rotating shaft of the motor 31 and located above the fixed block 32, so that when the workpiece is processed, the rotating shaft of the motor 31 drives the fan 8 to rotate at the same time, and the rotation of the fan 8 generates wind force, and the downward wind force can further blow part of the debris downward, so as to facilitate the collection of the debris;

[0097] In addition, a discharge port is provided on the base 51 and in the middle of the annular bracket 6 , and a worker may place a collection box or a collection bag below the discharge port to facilitate the collection of debris.

[0098] As an embodiment of the present invention, an electromagnet 9 is disposed on the outer side of the arc-shaped bracket 22, and the electromagnet 9 is fixedly connected to the side plate 52. An exhaust port 10 is disposed on the upper end of the airbag 23, and the exhaust port 10 is tilted downward, and a rubber plug 11 is disposed in the exhaust port 10;

[0099] During the wire drawing and polishing process of the workpiece, the arc bracket 22 is fixed in position under the action of the limiter. When the workpiece needs to be taken out after processing, the staff removes the limiter on the arc bracket 22, turns off the motor 31, and then energizes the electromagnet 9. The electromagnet 9 generates magnetism after being energized. At this time, the magnetic attraction of the electromagnet 9 drives the arc bracket 22 to move along the slide 21 to the side away from the workpiece. At this time, the wire drawing sandpaper 1 moves away from the workpiece surface along the arc bracket 22;

[0100] At this time, the staff controls the second hydraulic telescopic rod 34 to retract upward and return to its original position again, and at the same time takes out the rubber plug 11 in the exhaust port 10 of the airbag 23. Therefore, in the process of the second hydraulic telescopic rod 34 retracting upward to pull the workpiece upward, the gas in the airbag 23 is discharged downward from the exhaust port 10, and the discharged gas blows from top to bottom toward the outer surface of the workpiece moving upward, further blowing part of the debris on the surface of the workpiece downward, which is convenient for collecting the debris in the wire drawing process;

[0101] When the workpiece rises to a level where its lower surface is higher than the upper surface of the drawing sandpaper 1, the No. 2 hydraulic telescopic rod 34 is closed, the staff holds the workpiece in hand, and then controls the output end of the No. 1 hydraulic telescopic rod 33 to retract upward again. The No. 1 hydraulic telescopic rod 33 retracts upward and pulls the connecting rod 35 to move upward. The upward movement of the connecting rod 35 generates a pulling force on the splint 37. After the splint 37 is subjected to the pulling force, its lower end retracts inward. At this time, the two side surfaces of the splint 37 are away from the workpiece, the workpiece falls, and the staff removes the workpiece.

[0102] As an embodiment of the present invention, the airbag 23 is filled with a coolant;

[0103] By adopting the above technical solution, since the workpiece generates a lot of heat after repeated friction with the drawing sandpaper 1 during the wire drawing process, the surface temperature of the workpiece is relatively high. Therefore, a coolant is filled in the airbag 23, which can alleviate the phenomenon of high surface temperature of the workpiece during the wire drawing process and ensure that the liquid level of the coolant is lower than one quarter of the height of the airbag 23. When the airbag 23 is not inflated, the liquid level of the coolant is lower than the horizontal height of the air inlet 24, so as to avoid leakage of coolant when the airbag 23 is exhausted or affect the air intake effect of the air pump 4 on the airbag 23.

[0104] As an embodiment of the present invention, the annular bracket 6 is limited by a cable tie 12;

[0105] By adopting the above technical solution, since the arc-shaped bracket 22 is slidably connected on the base 51, a plurality of arc-shaped brackets 22 are arranged in a circular shape to form an annular bracket 6, and a cable tie 12 is wrapped around the outer surface of the annular bracket 6, so that the inner side of the arc-shaped bracket 22 contacts the end of the slide groove 21, and the outer side is fixed by the cable tie 12, so that the arc-shaped bracket 22 will not slide along the slide groove 21 and toward the side away from the workpiece.

[0106] Working principle: when it is necessary to draw the surface of a stainless steel tubular workpiece whose outer surface size has changed, the staff first holds the stainless steel tubular workpiece whose surface size has changed, and places it on two clamps 37, that is, the tubular workpiece is sleeved on the two clamps 37, and then starts the No. 1 hydraulic telescopic rod 33, the output end of the No. 1 hydraulic telescopic rod 33 extends downward, and the No. 1 hydraulic telescopic rod 33 extends downward to drive the connecting rod 35 welded to its output end to move downward. Since the connecting rod 35 is fixedly connected to the No. 1 mounting rod 36, two clamps 37 are symmetrically arranged on the No. 1 mounting rod 36, and the two clamps 37 are slidably connected to the No. 1 mounting rod 36, and the middle parts of the two clamps 37 are connected to the No. 2 mounting rod on the No. 1 support plate 53. The rod 38 is rotatably connected, and the No. 1 support plate 53 is fixedly connected to the hydraulic cylinder of the No. 1 hydraulic telescopic rod 33 through the L-shaped connecting rod 39, so that the distance between the No. 1 support plate 53 and the hydraulic cylinder of the No. 1 hydraulic telescopic rod 33 is constant. At this time, the No. 1 mounting rod 36 slidably connected to the upper ends of the two clamping plates 37 moves downward, while the No. 2 mounting rod 38 rotatably connected in the middle of the two clamping plates 37 is stationary. Therefore, after the two clamping plates 37 are pushed by the No. 1 mounting rod 36, their lower ends open to both sides of the No. 1 mounting rod 36. When the two clamping plates 37 are opened to a certain angle until their sides are in close contact with the inner surface of the tubular workpiece, the output end of the No. 1 hydraulic telescopic rod 33 is controlled to stop extending. At this time, the two clamping plates 37 complete the clamping and fixing of the tubular workpiece.

[0107] The two clamping plates 37 clamp and fix the tubular workpiece by contacting the inner surface of the tubular workpiece at their lower ends, instead of fastening by contacting the clamping plates 37 with the outer surface of the workpiece. The clamping is achieved from the inside of the workpiece, thus avoiding the wire drawing blind area of ​​the wire drawing sandpaper 1 when wire drawing and polishing the outer surface of the workpiece due to the existence of the clamping plates 37.

[0108] After the workpiece is clamped, the No. 2 hydraulic telescopic rod 34 is started, and the output end of the No. 2 hydraulic telescopic rod 34 extends downward. Since the output end of the No. 2 hydraulic telescopic rod 34 is welded to the upper surface of the No. 2 support plate 54, and the No. 2 support plate 54 is slidably connected to the side plate 52, the No. 2 support plate 54 is connected to the No. 1 support plate 53 through the motor 31, the fixing block 32, the No. 1 hydraulic telescopic rod 33, the connecting rod 35, the No. 1 mounting rod 36, the clamping plate 37, the No. 2 mounting rod 38 and the L-shaped connecting rod 39. At this time, the output end of the No. 1 hydraulic telescopic rod 33 is stationary, and the connecting rod 35 , a stable structure is formed between the clamping plate 37 and the workpiece. Therefore, when the No. 2 support plate 54 is pushed downward by the No. 2 hydraulic telescopic rod 34 and drives the No. 1 hydraulic telescopic rod 33 connected thereto to move downward, the clamping plate 37 and the No. 1 hydraulic telescopic rod 33 will not move relative to each other, so that the No. 2 support plate 54 moves downward to drive the clamping plate 37 to move downward, and the clamping plate 37 drives the workpiece to move downward, and the workpiece moves downward into the drawing and polishing assembly 2. When the upper surface of the workpiece is lower than the horizontal height of the upper surface of the drawing sandpaper 1, the output end of the No. 2 hydraulic telescopic rod 34 is controlled to stop moving;

[0109] Furthermore, since the two sides of the No. 1 support plate 53 are not in contact with the side plate 52, and the No. 1 support plate 53 is fixedly connected to the hydraulic cylinder of the No. 1 hydraulic telescopic rod 33 through the L-shaped connecting rod 39, the distance between the No. 1 hydraulic telescopic rod 33 and the No. 1 support plate 53 is fixed, so when the No. 2 support plate 54 moves downward, the No. 1 support plate 53 and the No. 2 support plate 54 are relatively stationary.

[0110] After the workpiece enters the wire drawing and polishing assembly 2, the staff pushes the arc bracket 22, and the arc bracket 22 moves along the slide groove 21 to one end of the slide groove 21 close to the center of the bottom plate, and then the cable tie 12 is used as a limiter to fix multiple arc brackets 22, and at this time, the arc bracket 22 forms a ring bracket 6;

[0111] Then, the air pump 4 is connected to the airbag 23 through the air inlet 24, and the airbag 23 is inflated by the air pump 4, and the airbag 23 gradually expands. Since the arc bracket 22 fixedly connected to one side of the airbag 23 is fixed, the airbag 23 expands toward the side away from the arc bracket 22, and the side of the airbag 23 away from the arc bracket 22 is fixedly connected with the drawing sandpaper 1. Therefore, when the airbag 23 gradually expands, it drives the drawing sandpaper 1 to move toward the side of the workpiece surface, and utilizes the fluidity of the gas and the elasticity of the airbag 23 to enable the airbag 23 to drive the drawing sandpaper 1 to better fit the workpiece surface. When the airbag 23 drives the drawing sandpaper 1 to be in close contact with the workpiece surface, the air pump 4 is controlled to stop supplying air to the airbag 23;

[0112] Then, the motor 31 is started, the rotation shaft of the motor 31 rotates to drive the fixed block 32 connected thereto to rotate, the rotation of the fixed block 32 drives the No. 1 hydraulic telescopic rod 33 to rotate, the rotation of the No. 1 hydraulic telescopic rod 33 drives the connecting rod 35 and the L-shaped connecting rod 39 to rotate, the rotation of the connecting rod 35 drives the clamping plate 37 to rotate, the clamping plate 37 drives the workpiece to rotate, and at the same time the L-shaped connecting rod drives the No. 1 support plate 53 to rotate, friction occurs between the rotating workpiece and the stationary wire drawing sandpaper 1, and the wire drawing polishing of the workpiece surface is completed;

[0113] Therefore, the elasticity of the airbag 23 and the fluidity of the gas drive the wire drawing sandpaper 1 to better fit the surface of the stainless steel tubular workpiece with changed outer surface dimensions, thereby ensuring the wire drawing effect of the wire drawing sandpaper 1 on the stainless steel pipe with uneven surface;

[0114] Furthermore, by setting the thickness of the airbag 23 to be no greater than 2 mm, the phenomenon that the deformation effect of the airbag 23 is deteriorated due to the excessive thickness of the airbag 23 is avoided, thereby ensuring the fit between the drawing sandpaper 1 and the surface of the workpiece;

[0115] At the same time, the staff can control the air intake of the airbag 23 through the air pump 4, and then control the moving distance of the wire drawing sandpaper 1 by controlling the expansion degree of the airbag 23, so that the wire drawing and polishing assembly 2 can be suitable for stainless steel tubular workpieces with different sizes and changing surface dimensions, thereby improving the actual use performance of the wire drawing and polishing equipment.
