Description

Technical Field

[0001] This invention relates to the field of metal composite pipe processing equipment, and in particular to a production equipment for aluminum-clad stainless steel composite pipes for liquid-cooled cabinets. Background Technology

[0002] In liquid-cooled cabinet heat dissipation systems, aluminum-clad stainless steel composite tubes are widely used to achieve a balance between efficient heat conduction and corrosion resistance. Current technology typically relies on multiple independent machines for the sequential processing of aluminum-clad stainless steel composite tubes. This involves first extruding or welding an aluminum layer onto the stainless steel tube surface, followed by post-processing steps such as drawing or rolling to ensure a tight bond between the two metal layers. However, the material transfer and repeated clamping between multiple machines result in a lengthy and inefficient production process. Furthermore, repeated clamping can introduce positioning errors, affecting the dimensional accuracy of the finished product and the consistency of the interlayer bonding. Additionally, the lack of coordination between various stages, such as precise positioning before aluminum cladding, preventing misalignment during cladding, timely weld treatment, and inner tube expansion, makes the entire production process highly dependent on manual intervention, hindering continuous and automated production. Therefore, this invention provides a production equipment for aluminum-clad stainless steel composite tubes used in liquid-cooled cabinets. Summary of the Invention

[0003] This invention addresses the shortcomings of existing technologies by providing a production equipment for aluminum-clad stainless steel composite tubes for liquid-cooled cabinets, overcoming the problems of fragmented processes, low integration, and difficulty in switching between production of different specifications in existing equipment.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a production equipment for aluminum-clad stainless steel composite tubes for liquid-cooled cabinets, comprising a base plate, a wrapping component, an auxiliary component, and a pushing component. The wrapping component includes a feed support plate, a shaping groove plate, and symmetrically movably mounted pushing strips. The surface of the pushing strip closest to the groove of the shaping groove plate is an arc-shaped surface. The groove on the shaping groove plate and the arc-shaped surface of the pushing strip are on the same circumferential surface. The shaping groove plate and the pushing strip are used to wrap aluminum sheets around stainless steel tubes. The auxiliary component includes a laser welding head and a grinding head. The pushing component includes an L-shaped carriage, a traction ring plate, a support core rod, and an expanding conical block. The expanding conical block is threaded to the end of the support core rod. An annular push block is provided on the L-shaped carriage, which is used to push the stainless steel tube to move on the support core rod. Six traction short rods are movably arranged in a circumferential array on the traction ring plate, which are used to assist the movement of the stainless steel tube during pushing.

[0005] Furthermore, the feed support plate is slidably mounted on the base plate, and a support long plate is fixedly mounted on the feed support plate. Bolts are provided between the support long plate and the shaping groove plate.

Auxiliary electric cylinder one and auxiliary electric cylinder two are fixedly mounted at both ends of the shifting plate, respectively. A laser welding head is fixedly mounted on the piston rod end of auxiliary electric cylinder one, and a grinding head is movably mounted on the piston rod end of auxiliary electric cylinder two. The laser welding head and the grinding head are used to realize the welding and grinding of the joint after the aluminum sheet wraps the stainless steel tube.

[0009] Furthermore, the support core rod is fixedly installed on the base plate, and when the aluminum sheet wraps around the stainless steel tube, the axis of the support core rod and the axis of the groove of the shaping groove plate are on the same straight line.

[0010] Furthermore, the L-shaped carriage and the traction ring plate are respectively set at both ends of the support core rod. The L-shaped carriage is slidably installed on the base plate.

Detailed Implementation

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0025] Example: Reference Figures 1-9 A production equipment for aluminum-clad stainless steel composite pipes for liquid-cooled cabinets includes a base plate 101. A wrapping assembly is mounted on the base plate 101, including a feed support plate 103 slidably mounted on the base plate 101. Feed screws 109 are symmetrically rotatably mounted on the base plate 101, each forming a helical pair with the feed support plate 103. A pulley is fixedly mounted at the lower end of each feed screw 109, and a transmission belt 111 connects the pulleys on the two feed screws 109. A feed motor 110 is also fixedly mounted on the base plate 101, with its output shaft fixedly connected to the corresponding feed screw 109. When the feed motor 110 is started, it drives the corresponding feed screw 109 to rotate. Under the action of the transmission belt 111, the two feed screws 109 rotate synchronously. Under the action of the feed screws 109, the feed support plate 103 moves up and down relative to the base plate 101.

[0026] A shaping groove plate 122 is provided on the feed support plate 103, and a support long plate 121 is fixedly installed on the feed support plate 103. The shaping groove plate 122 is located directly above the support long plate 121, and bolts are provided between the support long plate 121 and the shaping groove plate 122. The shaping groove plate 122 is fixedly installed on the support long plate 121 by bolts. A pusher plate 127 is also symmetrically and movably arranged on the feed support plate 103, and an arc-shaped electric cylinder 12 is symmetrically arranged on each pusher plate 127. 4. The axis of the arc-shaped electric cylinder 124 and the axis of the groove of the shaping groove plate 122 are on the same straight line. The arc-shaped electric cylinders 124 are all fixedly installed on the feed support plate 103. Bolts are provided between the push plate 127 and the piston rod end of the corresponding arc-shaped electric cylinder 124. That is, the push plate 127 and the piston rod of the corresponding arc-shaped electric cylinder 124 are fixedly connected by bolts. By synchronously starting the two arc-shaped electric cylinders 124 corresponding to the same push plate 127, the push plate 127 can be moved.

[0027] The surface of the pusher plate 127 closest to the groove of the shaping groove plate 122 is an arc-shaped surface. The groove on the shaping groove plate 122 and the arc-shaped surface of the pusher plate 127 are on the same circumferential surface. The shaping groove plate 122 and the pusher plate 127 are used to wrap the aluminum sheet around the stainless steel tube. In the initial position, the pusher plate 127 is in a horizontal state. At this time, a complete semi-circular groove is formed between the arc-shaped surfaces of the two pusher plates 127 and the groove on the shaping groove plate 122. The aluminum sheet is then placed flat on the upper surface of the two pusher plates 127, and then the stainless steel tube to be processed is placed on the arc-shaped groove on the shaping groove plate 122. At this time, the aluminum sheet deforms under the action of the stainless steel tube, and finally the axis of the stainless steel tube and the axis of the semi-circular groove are on the same straight line. That is, the aluminum sheet wraps around the lower half of the stainless steel tube. Then the arc-shaped electric cylinder 1 is activated. 24. This causes the two sliding plates 127 to rotate vertically. At this time, the two sliding plates 127 rotate relative to the axis of the stainless steel tube. During the rotation of the two sliding plates 127, the aluminum sheet located above the semi-circular groove moves towards the surface of the stainless steel tube. Under the action of the sliding plates 127, the aluminum sheet contacts the surface of the stainless steel tube. Finally, the two sliding plates 127 rotate to a vertical state. At this time, the two sides of the aluminum sheet are directly above and in an engaged state. That is, under the action of the sliding plates 127, the aluminum sheet completely wraps around the stainless steel tube.

[0028] A symmetrically sliding adjustment slide 123 is also mounted on the feed support plate 103. A bidirectional synchronous electric cylinder 125 is provided between the two adjustment slides 123. The bidirectional synchronous electric cylinder 125 is fixedly mounted on the feed support plate 103. The piston rod ends on both sides of the bidirectional synchronous electric cylinder 125 are fixedly connected to the corresponding adjustment slide 123. When the bidirectional synchronous electric cylinder 125 is activated, the two adjustment slides 123 can be moved towards each other synchronously or away from each other synchronously. A symmetrically fixed adjustment push block 128 is provided on each adjustment slide 123. The adjustment push block 128 is used to adjust the position of the aluminum sheet. After the aluminum sheet is placed on the upper surface of the two pusher plates 127, the bidirectional synchronous electric cylinder 125 is activated to move the two adjusting slides 123 toward each other, so that the two adjusting push blocks 128 arranged opposite to each other move toward each other. Under the action of the adjusting push blocks 128, the aluminum sheet on the pusher plate 127 is moved to the center position of the shaping groove plate 122. That is, under the action of the adjusting push blocks 128, the positioning and adjustment of the aluminum sheet position is realized.

[0029] The upper surface of each sliding plate 127 is also fixedly equipped with a strip-shaped vacuum suction plate 129, and the sides of each sliding plate 127 are also fixedly equipped with a vacuum generator 130, which is connected to the corresponding strip-shaped vacuum suction plate 129. After the adjusting push block 128 completes the positioning adjustment of the aluminum sheet, the two vacuum generators 130 are activated. Under the action of the strip-shaped vacuum suction plate 129, the aluminum sheet is adsorbed and fixed, thereby preventing the aluminum sheet from shifting position after the adjusting push block 128 releases the restriction on the aluminum sheet's position.

[0030] Both the shaping groove plate 122 and the pushing strip plate 127 are detachable structures, so that the shaping groove plate 122 and the pushing strip plate 127 can be replaced according to the size of the stainless steel tube to be processed.

[0031] An auxiliary assembly is provided on the base plate 101. This assembly includes a laser welding head 117 and a grinding head 120. It also includes an auxiliary carriage 136 slidably mounted on the side of the feed support plate 103. An auxiliary lead screw 113 is rotatably mounted on the feed support plate 103. The auxiliary lead screw 113 and the auxiliary carriage 136 form a helical pair. An auxiliary motor 137 is fixedly mounted on the feed support plate 103, and its output shaft is fixedly connected to the auxiliary lead screw 113. A shifting plate 114 is rotatably mounted on the auxiliary carriage 136. A shifting motor 115 is also fixedly mounted on the feed support plate 103. The output shaft of the shifting motor 115 is fixedly connected to the shifting plate 114. Auxiliary electric cylinder 116 and auxiliary electric cylinder 118 are fixedly installed at both ends of the shifting plate 114, respectively. The laser welding head 117 is fixedly installed at the piston rod end of the auxiliary electric cylinder 116. The grinding head 120 is movably disposed at the piston rod end of the auxiliary electric cylinder 118. A grinding motor 119 is fixedly installed at the piston rod end of the auxiliary electric cylinder 118. The grinding head 120 is fixedly installed on the output shaft of the grinding motor 119. The laser welding head 117 and the grinding head 120 are used to realize the welding and grinding of the joint after the aluminum sheet wraps the stainless steel tube.

[0032] After the pusher plate 127 completes the wrapping of the aluminum sheet around the stainless steel tube, the arc-shaped electric cylinder 124 is activated, causing the two pusher plates 127 to move away from each other, exposing the joint of the aluminum sheet. Then, the shifting motor 115 is activated to drive the shifting plate 114 to rotate, so that the laser welding head 117 moves directly above the joint of the aluminum sheet. Then, the auxiliary electric cylinder 116 is activated to drive the laser welding head 117 to move downward, so that the lower end of the laser welding head 117 is close to the joint of the aluminum sheet. Then, the auxiliary motor 137 is activated to drive the auxiliary lead screw 113 to rotate, so that the auxiliary slide 136 moves along the axis of the stainless steel tube. At this time, the laser welding head 117 is activated to weld the joint of the aluminum sheet. During the welding process, the pusher plate 127 is always in a pressing state on the aluminum sheet, thereby preventing the joint of the aluminum sheet from separating.

[0033] After the laser welding head 117 completes the welding at the joint of the aluminum sheet, and the welded area cools, the aluminum sheet forms an aluminum tube on the surface of the stainless steel tube. The arc-shaped electric cylinder 124 is activated to return the two pushing plates 127 to a horizontal position. Then, the shifting motor 115 is activated to rotate the grinding head 120 directly above the stainless steel tube containing the aluminum sheet. The auxiliary electric cylinder 118 is activated to drive the grinding head 120 downwards, bringing it into contact with the welded area of ​​the aluminum sheet. Then, the grinding motor 119 is activated to drive the grinding head 120 to rotate. With the assistance of the auxiliary motor 137, the grinding head 120 performs grinding on the welded area of ​​the aluminum sheet. It should be noted that the grinding head 120 has an arc-shaped groove in the middle, which can fit snugly against the joint of the aluminum sheet for grinding. The model of the grinding head 120 can be replaced according to requirements.

[0034] A pushing assembly is provided on the base plate 101. The pushing assembly includes an L-shaped slide 102, a traction ring plate 108, a support core rod 112, and an expansion cone block 126. The expansion cone block 126 is composed of a conical section and a cylindrical section. The L-shaped slide 102 and the traction ring plate 108 are respectively located at both ends of the support core rod 112. The support core rod 112 is fixedly installed on the base plate 101. The expansion cone block 126 is threaded to the end of the support core rod 112. The diameter of the expansion cone block 126 is larger than the diameter of the support core rod 112. When the aluminum sheet wraps the stainless steel tube, the axis of the support core rod 112 and the axis of the groove of the shaping groove plate 122 are on the same straight line.

[0035] The support core rod 112 and the stainless steel tube to be processed have a clearance fit, allowing the support core rod 112 and the expansion cone block 126 to be replaced according to the size of the stainless steel tube. Removing the expansion cone block 126 from the support core rod 112 allows the stainless steel tube to be processed to be placed onto the support core rod 112. When the expansion cone block 126 is fixed to the support core rod 112, its conical surface is located at the position closest to the support core rod 112.

[0036] The L-shaped carriage 102 is slidably mounted on the base plate 101. A lead screw 105 is rotatably mounted on the base plate 101. The lead screw 105 and the L-shaped carriage 102 form a helical pair. A push motor 107 is fixedly mounted on the base plate 101. The output shaft of the push motor 107 is fixedly connected to the lead screw 105. When the push motor 107 is started, it drives the lead screw 105 to rotate, which causes the L-shaped carriage 102 to move relative to the base plate 101. The axis of the lead screw 105 is parallel to the axis of the support core rod 112. That is, at this time, the L-shaped carriage 102 moves along the axis of the support core rod 112.

[0037] An annular pusher 131 is provided on the L-shaped slide 102. The annular pusher 131 is used to push the stainless steel tube to move on the support core rod 112. A bolt is provided between the L-shaped slide 102 and the annular pusher 131. The L-shaped slide 102 and the annular pusher 131 are fixedly connected by the bolt. The axis of the annular pusher 131 and the support core rod 112 are on the same straight line. After the stainless steel tube is fitted onto the support core rod 112 and the expanding conical block 126 is fixed onto the support core rod 112, the push motor 107 is started to drive the push screw 105 to rotate, causing the L-shaped slide 102 to move closer to the expanding conical block 126. The annular push block 131 moves synchronously, allowing it to contact the end of the stainless steel tube furthest from the expanding conical block 126. Under the action of the annular push block 131, the stainless steel tube moves closer to the expanding conical block 126, eventually contacting the conical surface of the expanding conical block 126. At this point, the stainless steel tube is fixed by the action of the annular push block 131 and the expanding conical block 126. The annular push block 131 and the support core rod 112 are clearance-fitted. When the support core rod 112 is changed according to the size of the stainless steel tube to be processed, the annular push block 131 is changed synchronously.

[0038] A U-shaped slide 135 is fixedly installed on the traction ring plate 108. The U-shaped slide 135 is slidably installed on the base plate 101. The axes of the traction ring plate 108 and the support core rod 112 are on the same straight line. A traction screw 104 is rotatably installed on the base plate 101. The traction screw 104 and the U-shaped slide 135 form a helical pair. A traction motor 106 is fixedly installed on the base plate 101. The output shaft of the traction motor 106 is fixedly connected to the traction screw 104. When the traction motor 106 is started, it drives the traction screw 104 to rotate, which causes the U-shaped slide 135 to move relative to the base plate 101. The axes of the traction screw 104 and the push screw 105 are on the same straight line.

[0039] In the initial position, the feed support plate 103 is located closest to the lower surface of the base plate 101. At this time, the support core rod 112 is located directly above the shaping groove plate 122. The stainless steel tube to be processed is placed on the support core rod 112, and the stainless steel tube is fixed on the support core rod 112 under the action of the expansion cone block 126 and the annular push block 131. Then, the aluminum sheet is placed on the push strip plate 127. After the adjustment push block 128 completes the adjustment of the position of the aluminum sheet, the strip vacuum suction plate 129 completes the adsorption and fixation of the aluminum sheet. Then, the feed support plate 103 is driven to move upward, and the stainless steel tube on the support core rod 112 contacts the upper surface of the aluminum sheet. At this time, the strip vacuum suction plate 129 releases the adsorption and fixation of the aluminum sheet. The feed support plate 103 continues to move upward, and the aluminum sheet deforms under the action of the stainless steel tube, so that the axis of the stainless steel tube and the axis of the semi-circular groove are on the same straight line. Then, the push strip plate 127 completes the wrapping of the stainless steel tube by the aluminum sheets on both sides.

[0040] The traction ring plate 108 is movably arranged with six traction rods 133 in a circumferential array. The traction rods 133 are used to assist in supporting the movement of the stainless steel tube during pushing. The traction ring plate 108 is fixedly installed with six traction electric cylinders 132 in a circumferential array. The piston rod end of each traction electric cylinder 132 is fixedly provided with a telescopic rod 134. The traction rods 133 are respectively fixedly installed on the ends of the telescopic rods 134 closest to the axis of the traction ring plate 108. A spring is provided between the traction rods 133 and the corresponding telescopic rods 134.

[0041] In the initial position, the telescopic rod 134 is located at the position furthest from the axis of the traction ring plate 108, and at this time, the spring between the traction short rod 133 and the telescopic rod 134 is not compressed. When the aluminum sheet wraps the stainless steel tube on the support core rod 112, the six traction electric cylinders 132 make the traction short rod 133 contact the surface of the expansion cone block 126, and the traction short rod 133 and the telescopic rod 134 are in the maximum compression state. That is, under the action of the six traction short rods 133, the expansion cone block 126 will not move freely, thus achieving auxiliary support and fixation for the other end of the support core rod 112, thereby preventing the support core rod 112 from bending and deforming when the feed support plate 103 moves upward.

[0042] After welding and grinding the aluminum tube on the stainless steel tube of the support core rod 112, the feed support plate 103 returns to its initial position, that is, it returns to the position closest to the lower surface of the base plate 101. At this time, the traction cylinder 132 is activated to adjust the traction rod 133 and the telescopic rod 134, causing the traction rod 133 to disengage from the expanding cone block 126. Then, the push motor 107 is activated to drive the L-shaped carriage 102 to move closer to the expanding cone block 126. The annular push block 131 moves synchronously. Under the action of the annular push block 131, the stainless steel tube moves closer to the expanding cone block 126. Under the action of the conical surface of the expanding conical block 126, the inner diameter of the stainless steel tube expands. The expanded stainless steel tube is tightly attached to the inner wall of the aluminum tube. When the expanded stainless steel tube moves to the cylindrical section position of the expanding conical block 126, the six traction electric cylinders 132 are activated so that the traction short rods 133 all contact the outer surface of the aluminum tube on the stainless steel tube. The annular push block 131 continues to push the stainless steel tube to move. At this time, the traction motor 106 is activated so that the traction ring plate 108 moves synchronously. That is, under the action of the six traction short rods 133, the end of the stainless steel tube is moved synchronously, which provides auxiliary support to the end of the expanded stainless steel tube and prevents the stainless steel tube from bending and deforming.

[0043] Working principle: The stainless steel tube to be processed is placed on the support core rod 112 and fixed by the annular pusher block 131 and the expanding conical block 126. The aluminum sheet to be used is placed on the pushing plate 127 and the position of the aluminum sheet is adjusted by the adjusting pusher block 128 and the strip vacuum suction plate 129. Then, the feed support plate 103 is driven to move upward, and the aluminum sheet is attached to the surface of the stainless steel tube at the semi-circular groove. Then, the pushing plate 127 is driven to move by the arc-shaped electric cylinder 124 so that the aluminum sheet completely covers the surface of the stainless steel tube. Then, the welding of the aluminum sheet joint is completed by the laser welding head 117. At this time, the aluminum sheet forms a complete aluminum tube on the surface of the stainless steel tube. Then, the grinding head 120 is used to grind the welded part of the aluminum tube.

[0044] After grinding the joint of the aluminum tube, the wrapping component and auxiliary component are returned to their initial positions. Then, the inner diameter of the stainless steel tube is expanded by the pushing component, making the stainless steel tube larger and thus allowing it to fit tightly against the inner wall of the aluminum tube.

[0045] This invention is not limited to the specific embodiments described above. Any modifications made by those skilled in the art based on the above concept without creative effort are within the protection scope of this invention.
