Description

Technical Field

[0001] The invention relates to the technical field of tube rolling, in particular to a rolling device and a rolling method for an aluminum heat dissipation bushing tube. Background Art

[0002] Aluminum heat sink tube is an important material. It has excellent corrosion resistance, high strength, light weight and other characteristics, so it has been widely used in various fields.

[0003] The production of aluminum heat sink tubes primarily involves two processes: extrusion and rolling. Extrusion involves pressing an aluminum alloy billet through a die to form it into a tubular shape. During this process, the aluminum alloy billet is subjected to high temperature and high pressure, causing it to undergo plastic deformation, ultimately forming a seamless tube. Rolling involves passing the extruded billet through a rolling mill to achieve the desired size and shape.

[0004] During rolling, existing rolling mills generally control the reciprocating motion of rollers and apply extrusion pressure to the casing to roll it into a pipe of a certain thickness. However, if the extrusion pressure is only applied in one direction to the casing, the thickness of the produced pipe may be inconsistent. In addition, when preparing casings of different thicknesses, the existing rolling mill needs to stop and replace specific rollers, resulting in reduced production efficiency.

DETAILED DESCRIPTION

[0043] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0044] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0045] See also Figures 1 to 11In an embodiment of the present invention, a rolling device for an aluminum heat dissipation bushing includes: a truss 1, a lifting plate 2, a support tube 26, an intermittent translation mechanism, a receiving frame 10, a toothed assembly, a rotary rolling mechanism, a roller 12, a clamping and regulating mechanism, a clamping plate 31, and an intermittent rotation assembly. When rolling the bushing, in order to ensure that the bushing can be fully rolled, it is necessary to control the intermittent rotation of the bushing. Therefore, when rolling the bushing, the bushing can be inserted into the support tube 26 and, under the action of the clamping and regulating mechanism, the bushing is fixed by the clamping plate 31 so that the bushing cooperates with the roller 12. At the same time, the intermittent translation mechanism works and drives the receiving frame. 10 moves along the length direction of the sleeve, thereby driving the roller 12 to move through the rotary rolling mechanism. The receiving frame 10 also drives the engagement component to move, and drives the roller 12 to rotate through the rotary rolling mechanism. Under the action of the roller 12, the sleeve is rolled. When the roller 12 moves to the end of the stroke, the intermittent translation mechanism also drives the support tube 26 to rotate intermittently through the intermittent rotation component, so as to control the intermittent rotation of the sleeve through the clamping control mechanism and the clamping plate 31, thereby ensuring comprehensive processing of the sleeve. The rotary rolling mechanism can also adjust the rotation angle of the roller 12 to change the size of the sleeve rolling, thereby increasing the applicability of the device.

[0046] The details are as follows, including:

[0047] A truss 1 and a lifting plate 2 mounted on the truss 1, wherein a support tube 26 is rotatably mounted on the truss 1;

[0048] Also includes:

[0049] See also Figure 1-Figure 3 、 Figure 5 、 Figure 8 , an intermittent translation mechanism is arranged on the lifting plate 2, and a receiving frame 10 is connected to the intermittent translation mechanism. The intermittent translation mechanism is used to drive the receiving frame 10 to intermittently reciprocate along the length direction of the lifting plate 2. The intermittent translation mechanism includes a guide rod 6 rotatably mounted on the lifting plate 2 and symmetrically arranged, and a guide sleeve 7 is movably mounted on the guide rod 6. The side wall of the guide sleeve 7 is provided with a connecting plate 8, and the connecting plate 8 is fixedly connected to the receiving frame 10; it also includes a follower plate 9 mounted on the connecting plate 8 The follower plate 9 is provided with a transverse groove 901 and an arc-shaped groove 902, and the transverse groove 901 is symmetrically arranged. The lifting plate 2 is provided with a driving component connected to the transverse groove 901 and the arc-shaped groove 902, wherein the driving component includes a rotating plate 4 rotatably mounted on the lifting plate 2, and the rotating shaft of the rotating plate 4 is connected to the output shaft of the motor 3 mounted on the lifting plate 2. The rotating plate 4 is provided with a clamping column 5 at one end away from the motor 3, and the clamping column 5 is slidably connected to the transverse groove 901 and the arc-shaped groove 902.

[0050] In detail, there are two transverse grooves 901, and the arc groove 902 is located in the middle of the two transverse grooves 901, and the two ends of the arc groove 902 are connected to the ends of the transverse groove 901. The circumferential radius of the arc groove 902 is equal to the rotation radius of the clamping column 5. When rolling the sleeve, the sleeve to be processed can be inserted into the support tube 26, and a steel pipe for limiting the inner diameter of the sleeve is inserted into the sleeve to ensure that when the outer wall of the sleeve is subjected to extrusion pressure, the inner diameter of the sleeve is maintained within the required requirements under the action of the steel pipe. In the initial state, the rotating plate 4 is located in a position parallel to the guide rod 6, so that the clamping column 5 is located in the arc groove 90 2 so that the guide sleeve 7 is located at the end of the stroke of the guide rod 6 toward the support tube 26. When rolling is required, the motor 3 works and drives the rotating plate 4 to rotate, thereby driving the clamping column 5 to move. The clamping column 5 will slide along the trajectory of the arc groove 902, and the follower plate 9 remains stationary. When the clamping column 5 leaves the arc groove 902 and enters one of the transverse grooves 901, the follower plate 9 moves and drives the guide sleeve 7 to move along the length direction of the guide rod 6 through the connecting plate 8. Since the guide rod 6 and the guide sleeve 7 have a guiding function, the follower plate 9 will not deviate during movement.

[0051] When the post 5 is out of the horizontal groove 901 and returns to the middle position of the arc groove 902, the guide sleeve 7 returns to the initial position again, and the above steps are repeated to achieve the effect of controlling the intermittent reciprocating motion of the receiving frame 10.

[0052] See also Figure 1-Figure 3 、 Figure 5 、 Figure 6 , a gearing assembly is arranged on the supporting frame 10, and the gearing assembly includes a second rotating rod 20 rotatably mounted on the supporting frame 10 and symmetrically arranged, a gear 21 is provided at the end of the second rotating rod 20, and a rack plate 22 meshing with the gear 21 is provided on the truss 1.

[0053] It should be noted that the rack plate 22 is symmetrically arranged. In the initial state, the gear 21 is located at the end of the stroke on one side of the rack plate 22. When the sleeve needs to be rolled, the receiving frame 10 will move along the length direction of the guide rod 6, and the receiving frame 10 will also drive the No. 2 rotating rod 20 to move, thereby driving the gear 21 to move along the length direction of the rack plate 22. Under the action of the rack plate 22, the gear 21 rotates, thereby driving the rotary rolling mechanism to move through the No. 2 rotating rod 20 to drive the roller 12 to rotate. Among them, under the action of the rack plate 22, the two gears 21 rotate in opposite directions to control the opposite rotation directions of the two No. 2 rotating rods 20.

[0054] See also Figure 1-Figure 7 、 Figure 11 The receiving frame 10 is also provided with a rotary rolling mechanism connected to the gearing assembly, and the rotary rolling mechanism is connected to a symmetrically arranged roller 12. The gearing assembly can drive the roller 12 to move in the horizontal direction while rotating through the rotary rolling mechanism when the receiving frame 10 moves. The rotary rolling mechanism includes a No. 1 rotating rod 11 rotatably mounted on the receiving frame 10 and symmetrically arranged. The No. 1 rotating rod 11 is fixedly connected to the roller 12, and a fixed cone 13 is provided on the No. 1 rotating rod 11. A movable sleeve 15 is movably mounted on the No. 1 rotating rod 11, and a movable sleeve 15 is provided There is a movable cone disc 16; it also includes a cylinder 23 mounted on the receiving frame 10, and a movable plate 24 rotatably connected to the movable sleeve 15 is provided on the output end of the cylinder 23, and a driven assembly connected to the No. 2 rotating rod 20 is provided on the movable cone disc 16, wherein the driven assembly includes a plurality of slots 14 respectively opened on the fixed cone disc 13 and the movable cone disc 16 and equidistantly distributed on the circumference, a limit rod 17 is slidably installed in the slot 14, and an arc-shaped plate 18 is provided on the end of the limit rod 17 away from the slot 14, and a No. 1 belt 19 rotatably connected to the No. 2 rotating rod 20 is sleeved on the arc-shaped plate 18.

[0055] Furthermore, the radius of the roller 12 gradually decreases, and the two rollers 12 fit together and form a circular hole. As the rollers 12 rotate, the diameter of the hole formed by the combination will gradually increase or decrease. The sleeve is located in the middle position of the two rollers 12. In the initial state, under the action of the cylinder 23, the movable plate 24 is located at the end of the stroke toward the receiving frame 10. Under the action of the movable sleeve 15, the distance between the movable cone disc 16 and the fixed cone disc 13 is maximized. The limit rod 17 is located at the end of the stroke on one side of the slot 14, so that the distance between the arc plates 18 is minimized. The roller 12 is located at the end of the stroke toward the support tube 26, and the hole formed by the combination is the largest. The sleeve passes through the hole. When the sleeve needs to be rolled, the receiving frame 10 will move along the length direction of the guide rod 6 and drive the roller 12 along the No. 1 rotating rod 11. The guide rod 6 moves in the length direction. At the same time, under the action of the gear 21 and the rack plate 22, the No. 2 rotating rod 20 rotates, thereby driving the arc plate 18 to move through the No. 1 belt 19. Under the action of the arc plate 18, the fixed cone disc 13 and the movable cone disc 16 are driven to rotate through the limit rod 17 and the slot 14, thereby driving the movable sleeve 15 and the No. 1 rotating rod 11 to rotate. The No. 1 rotating rod 11 will also drive the roller 12 to rotate. As the roller 12 rotates, the aperture formed by its combination will gradually decrease to continuously apply extrusion pressure to the casing. Since a steel pipe is inserted in the casing, the inner diameter of the casing will not change. Therefore, the thickness of the casing will gradually decrease until the roller 12 moves to the end of the stroke away from the support tube 26. The rotation angle of the roller 12 reaches the maximum, the aperture formed by the combination is the minimum, and the thickness of the sleeve is squeezed to the required state.

[0056] Preferably, since the greater the rotation angle of the roller 12, the smallest the hole formed by the combination thereof, resulting in a smaller outer diameter of the sleeve, if the outer diameter of the sleeve needs to be increased, at this time, under the action of the cylinder 23, the movable plate 24 is driven to move in the direction away from the receiving frame 10, thereby driving the movable sleeve 15 to move, and the movable sleeve 15 will also drive the movable cone disk 16 to move toward the fixed cone disk 13, and under the action of the slot 14 and the limit rod 17, the spacing between the arc plates 18 is increased. Since the No. 1 belt 19 can be stretched or contracted to a certain extent, the No. 1 belt 19 is stretched under the action of the arc plate 18. At this time, the rotation speed of the No. 2 rotating rod 20 remains unchanged, and the rotation speed of the No. 1 rotating rod 11 is reduced. Therefore, under the condition that the reciprocating stroke of the roller 12 remains unchanged, the rotation angle of the roller 12 is reduced. Therefore, when the roller 12 moves to the end of the stroke, the diameter of the hole formed by the combination thereof increases to adjust the outer diameter of the sleeve.

[0057] See also Figure 1 、 Figure 2 、 Figure 9, a clamping and regulating mechanism is provided on the support tube 26, and a symmetrically arranged card plate 31 is connected to the clamping and regulating mechanism. The clamping and regulating mechanism includes a support plate 27 installed on the support tube 26, and a symmetrically arranged slide groove 28 is provided on the support plate 27. A sliding block 29 is slidably installed in the slide groove 28, and a support rod 30 passing through the support plate 27 is provided on the sliding block 29. The support rod 30 is fixedly connected to the card plate 31, and the support tube 26 is provided with a symmetrically arranged slide groove 28. The guide assembly is connected to the sliding block 29, wherein the guide assembly includes a support plate 33 installed on the truss 1 and fixedly connected to the support tube 26, and the support plate 33 is provided with a symmetrically arranged annular groove 3301 and a limit groove 3302, and the end of the annular groove 3301 is connected to the end of the limit groove 3302; and also includes a protruding column 32 installed on the sliding block 29, and the protruding column 32 is slidably connected to the annular groove 3301 and the limit groove 3302.

[0058] Furthermore, there are two annular grooves 3301 and two limiting grooves 3302, and the limiting grooves 3302 are arranged in a convex wave shape. The two ends of the limiting groove 3302 are respectively connected to the ends of the annular groove 3301. In the initial state, the protruding column 32 is located at the center of the limiting groove 3302, so that the distance between the two sliding blocks 29 is maximized. The sliding blocks 29 also control the distance between the card plates 31 to be maximized through the support rod 30. At this time, the sleeve can be inserted into the support tube 26 and pass through between the card plate 31 and the roller 12. When the sleeve needs to be processed, at this time, under the action of the intermittent rotating component, the support tube 26 is driven to rotate, thereby driving the support plate 27 When rotating, the support plate 27 will drive the sliding block 29 to move through the slide groove 28, and the sliding block 29 will control the protruding column 32 to slide along the trajectory of the limiting groove 3302. Under the action of the limiting groove 3302 and the protruding column 32, the sliding block 29 moves along the length direction of the slide groove 28 and moves in the direction of approaching each other. The sliding block 29 will also drive the clamping plate 31 to move through the support rod 30. When the protruding column 32 moves to the connection position of the limiting groove 3302 and the annular groove 3301, the clamping plate 31 abuts against the sleeve and fixes the sleeve. At this time, the intermittent rotation component no longer controls the rotation of the support tube 26, and the sleeve is rolled under the action of the roller 12.

[0059] Preferably, after the roller 12 reciprocates once, the intermittent rotation component will control the support tube 26 to intermittently rotate a certain angle, thereby controlling the sleeve to rotate a certain angle through the support plate 27 and the clamping plate 31, so that the protruding column 32 slides in the annular groove 3301, thereby ensuring that the clamping plate 31 will not separate from the sleeve when the sleeve is controlled to rotate. When the protruding column 32 moves into the annular groove 3301 again, the clamping plate 31 separates from the sleeve. At this time, the sleeve can be controlled to move forward a certain distance to continue rolling the sleeve.

[0060] See also Figure 1 、 Figure 2 、 Figure 5 、 Figure 8 、 Figure 10 , the support tube 26 is also provided with an intermittent rotation component connected to the intermittent translation mechanism, and the intermittent rotation component can drive the support tube 26 to rotate intermittently, so as to control the clamping plate 31 to move closer to or away from each other through the clamping and regulating mechanism. The intermittent rotation component includes a long straight groove 601, a first inclined groove 602, a short straight groove 603, and a second inclined groove 604 opened on the guide rod 6, and a limit block 701 is provided on the inner wall of the guide sleeve 7. The limit block 701 is slidably connected to the long straight groove 601, the first inclined groove 602, the short straight groove 603, and the second inclined groove 604; it also includes a No. 2 belt 25 which is sleeved on the guide rod 6 and rotatably connected to the support tube 26.

[0061] To elaborate, both ends of the first inclined groove 602 are connected to one end of the long straight groove 601 and the short straight groove 603, one end of the second inclined groove 604 is connected to the other end of the short straight groove 603, and the other end is connected to the position of the long straight groove 601 toward the side of the support tube 26. In the initial state, the limit block 701 is located at the connection position of the first inclined groove 602 and the short straight groove 603. When the guide sleeve 7 moves in the direction away from the support tube 26, the limit block 701 will slide along the track of the short straight groove 603 and enter the second inclined groove 604, causing the guide rod 6 to rotate, thereby driving the support tube 26 to rotate through the second belt 25, so that the protruding column 32 is in the limit groove. 3302 until the protruding column 32 disengages from the limiting groove 3302 and enters the annular groove 3301. At this time, the limiting block 701 just disengages from the second inclined groove 604 and enters the long straight groove 601. The guide rod 6 stops rotating. After the roller 12 reciprocates once, the limiting block 701 will pass through the long straight groove 601 and enter the first inclined groove 602, so that the guide rod 6 rotates a certain angle again to control the rotation of the sleeve through the clamping plate 31 until the limiting block 701 returns to the first inclined groove 602 and the short straight groove 603. The above steps are repeated to realize that when the sleeve is rolled, the sleeve is controlled to rotate intermittently by a certain angle to fully roll the sleeve.

[0062] A rolling method for an aluminum heat dissipation bushing tube comprises the following steps:

[0063] Step 1: Insert the sleeve to be processed into the support tube 26 and fix the support tube 26 through the clamping plate 31 under the action of the clamping and regulating mechanism. The sleeve will cooperate with the roller 12.

[0064] Step 2: During rolling, the intermittent translation mechanism works and drives the rotary rolling mechanism to move through the receiving frame 10, thereby driving the rollers 12 to intermittently reciprocate along the length direction of the casing;

[0065] Step 3: The receiving frame 10 also drives the gear assembly to move, so as to control the rotation of the roller 12 through the rotary rolling mechanism. Under the action of the roller 12, the casing is rolled;

[0066] Step 4: In order to ensure that the sleeve is fully rolled, the intermittent translation mechanism will also drive the support tube 26 to rotate intermittently through the intermittent rotation component, so as to drive the sleeve to rotate through the clamping and regulating mechanism and the clamping plate 31, thereby changing the working position of the sleeve and the roller 12 to achieve the effect of full rolling.
