Description

Technical Field

[0001] This utility model belongs to the field of heat-conducting copper tube flattening technology, specifically relating to a heat sink heat-conducting copper tube flattening fixture. Background Technology

[0002] With the continuous upgrading of computer hardware performance, the high heat generated by the equipment places extremely high demands on the heat dissipation efficiency of the heat sink. The heat-conducting copper pipes inside the heat sink are key components for heat conduction. Flattening them can significantly improve heat dissipation and facilitate installation and layout. Flattening the heat-conducting copper pipes requires relevant jigs.

[0003] However, existing radiator heat pipe flattening fixtures have revealed many thorny problems in actual operation. The fixture must be opened first, then the radiator is placed, then the radiator is lifted and stabilized at a relative height, and the support plate supporting the radiator base is inserted. However, due to the unreasonable internal space structure design of the fixture, the process of placing the radiator is extremely inconvenient. The operating space is narrow, and the operator often needs to repeatedly adjust the angle and position, which consumes a lot of energy and time.

[0004] After the flattening process, removing the radiator is equally challenging. The radiator is tightly integrated with the fixture, and the lack of a convenient separation mechanism makes lifting it difficult. Forced operation can easily deform the copper tubes, potentially damaging the internal heat-conducting structure and severely impacting thermal conductivity. Furthermore, the entire process is cumbersome and complex, with each step from insertion to removal consuming significant time, greatly reducing production efficiency. This is undoubtedly a bottleneck problem that urgently needs to be addressed in the radiator manufacturing industry, which strives for high-efficiency production. It not only affects product efficiency but also increases scrap rates and production costs. Utility Model Content

[0005] The purpose of this utility model is to provide a flattening fixture for heat-conducting copper tubes of radiators, which aims to solve the technical problems of low production efficiency and high scrap rate of existing heat-conducting copper tube flattening fixtures.

[0006] To achieve the above objectives, this utility model provides a flattening fixture for heat-conducting copper pipes of a radiator, characterized in that: it includes a fixed plate, on which a support mechanism and a lifting device are provided; the support mechanism consists of a support frame, a top plate, a limiting frame, a limiting post, and a support plate; the support frame is fixedly disposed on both sides of the fixed plate, the top plate is fixed above the support frame, and the limiting frame and limiting post are disposed on the top surface of the top plate; the support plate is intersected with the top plate and extends through the top of the top plate; the lifting device is disposed in the support mechanism and includes a lifting plate, a positioning frame, a slide rail, and a telescopic mechanism. The system includes a tube, a spring, electromagnet one, electromagnet two, and a height-adjusting frame. The lifting plate is located below the pre-drilled hole, and a positioning frame is located above the lifting plate. The slide rail is located above the fixed plate and on both sides of the lifting plate. The telescopic tube is located on the fixed plate and corresponds to the pre-drilled hole. A spring is installed inside the telescopic tube. Electromagnet one is located at the bottom of the two ends of the lifting plate that are not connected to the slide rail. Electromagnet two is located below electromagnet one. The magnetic poles generated by electromagnet one and electromagnet two after being energized are of the same polarity. A height-adjusting frame is located below electromagnet two to support it.

[0007] Preferably, the top plate is provided with a reserved hole for the radiator to pass through and for limiting the position of the support plate on the top plate.

[0008] Preferably, the limiting frame is disposed on the top surface of the top plate to limit the position of the radiator base; the limiting post is fixed to the top surface of the top plate and cooperates with the holes at the four corners of the radiator base to assist the limiting frame in limiting the position of the radiator and to enable the radiator to be placed smoothly in the designated position.

[0009] Preferably, the two ends of the support plate protrude from both sides of the top plate, which facilitates its insertion into and removal from the pre-drilled holes in the top plate.

[0010] Preferably, the lifting plate is located below the reserved hole and its shape matches the reserved hole. It is used to place the radiator and drive the radiator to move up and down. A positioning frame is fixedly provided above the radiator to limit the position of the radiator.

[0011] Preferably, the slide rail is located above the fixed plate and on both sides of the lifting plate, and its two inner surfaces are on the same plane as the inner surface of the pre-reserved hole in the top plate, and are connected to both ends of the lifting plate to limit the movement direction of the lifting plate.

[0012] Preferably, the telescopic tube is fixedly mounted on the fixed plate and corresponding to the reserved hole. It consists of an inner tube and an outer tube. The bottom of the outer tube is fixedly connected to the fixed plate, and the top of the inner tube is fixedly connected to the lifting plate. It is used to support the lifting plate and the auxiliary slide rail restricts the range of motion of the lifting plate.

[0013] Preferably, the spring is located inside the telescopic tube, with its bottom contacting the fixed plate and its top contacting the lifting plate. When the spring is extended, it can lift the lifting plate. Under the weight of the radiator, the spring contracts, and at this time, the top surface of the radiator body is lower than the top surface of the top plate, and the distance between the bottom surface of the radiator base and the bottom surface of the top plate is sufficient for the support plate to be inserted.

[0014] Preferably, when the first electromagnet is energized, the magnetic force generated by the first electromagnet can drive the lifting plate to descend and thus come into contact with the second electromagnet.

[0015] Preferably, when electromagnet one and electromagnet two are energized, they repel each other and when de-energized, they have no magnetic force, thereby causing electromagnet two to push electromagnet one, and electromagnet one to drive the lifting plate to move the radiator upward.

[0016] The above-mentioned technical solutions in the heat sink heat-conducting copper tube flattening fixture provided in this embodiment of the utility model have at least one of the following technical effects:

[0017] This utility model discloses a flattening fixture for heat-conducting copper tubes in radiators. Through the design of a lifting mechanism, and with the coordinated operation of a telescopic tube below the lifting plate, a spring, and two pairs of electromagnets on both sides, the placement and removal of radiators becomes easy and smooth. When placing or removing the radiator, simply controlling the on / off state of the electromagnets precisely achieves the lifting and lowering action of the lifting plate, stabilizing the radiator at the required height. This allows for direct insertion and removal of the support plate between the heat sink and the base without manual adjustment of the radiator height. Furthermore, when removing the radiator, it rises to a height that allows the heat sink fins to protrude from the top plate, enabling workers to directly lift the main body of the radiator. This achieves a smooth and gentle separation operation, avoiding the need to lift the base and pull out the main body of the radiator along with the copper tubes. This prevents the copper tubes from being pulled and squeezed, maximizing the protection of their integrity and ensuring that their internal heat-conducting structure is not damaged. This, in turn, guarantees the thermal conductivity and product quality of the radiator.

[0018] The heat-conducting copper tube flattening fixture of this utility model, with the cooperation of the support mechanism and the lifting device, forms an efficient heat sink picking and placing mechanism, which enables the rolling machine to quickly connect the flattening work of the heat-conducting copper tube of the heat sink, reduces the waiting time between processes, greatly increases the number of copper tubes flattened per unit time, and significantly improves production efficiency.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the embodiments of the present invention, and should not be construed as limiting the present invention.

Therefore, they should not be construed as limitations on this utility model.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0031] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0032] In one embodiment of this utility model, such as Figure 1-3 As shown, a flattening fixture for heat-conducting copper tubes of a radiator is provided, including a fixed plate 10, a support mechanism 20, and a lifting device 30. The fixed plate 10 is fixed in the conveying mechanism of a tube rolling machine, and the fixture moves the radiator under the drive of the conveying mechanism. The support mechanism 20 is vertically fixed to the fixed plate 10, and the support mechanism 20 cooperates with the lifting device 30 to support and fix the radiator. The lifting device 30 is disposed in the support mechanism 20, and the lifting device 30 cooperates with the support mechanism 20 to limit the position of the radiator, and at the same time, to position the radiator to the required height.

[0033] The support mechanism 20 includes: a support frame 21, a top plate 22, a limiting frame 23, a limiting post 24, and a support plate 25. The support frame 21 is fixedly mounted on both sides of the fixed plate 10, and the support frame 21 serves to support the top plate 22. The top plate 22 is fixed above the support frame 21, and the top plate 22 serves to support the support plate 25 and the radiator base. The top plate 22 has a reserved hole 221, which allows the radiator to pass through and restricts the position of the support plate 25 on the top plate 22.

[0034] The top surface of the top plate 22 is provided with a limiting frame 23. When the heat dissipation copper pipe of the radiator is placed in the support mechanism 20 to perform the flattening operation, the limiting frame 23 plays the role of limiting the position of the radiator base.

[0035] The limiting frame 23 is also provided with limiting posts 24, which are fixed to the top surface of the top plate 22. The limiting posts 24 cooperate with the holes at the four corners of the radiator base to assist the limiting frame 23 in limiting the position of the radiator. At the same time, the setting of the limiting posts 24 enables the radiator to be placed in the designated position more smoothly when it is inserted into the support mechanism 20.

[0036] The support plate 25 is intersecting with the top plate 22, and the support plate 25 extends through the top plate 22. During the flattening operation of the radiator's copper heat dissipation tubes, the support plate 25 is inserted into the pre-drilled hole 221 in the top plate 22, and is embedded in the top plate 22 under the action of the pre-drilled hole 221, thus restricting the position of the support plate 25 within the top plate 22 and preventing horizontal displacement. The two ends of the support plate 25 protrude from both sides of the top plate 22, making it easier and faster to insert and remove the support plate 25 from the pre-drilled hole 221 in the top plate 22. The support plate 25 serves to support the radiator base during the flattening of the heat dissipation copper tubes by the tube rolling machine.

[0037] The lifting device 30 includes: a lifting plate 31, a positioning frame 32, a slide rail 33, a telescopic tube 34, a spring 35, an electromagnet 1 36, an electromagnet 2 37, and a height-increasing frame 38.

[0038] The lifting plate 31 is located below the pre-drilled hole 221 and its shape matches the pre-drilled hole 221. This allows the lifting plate 31 to move into the pre-drilled hole 221 under the driving action of the lifting device 30, making it easier and faster to insert the radiator. The lifting plate 31 serves to place the radiator and drive its up-and-down movement. A positioning frame 32 is fixedly provided above the lifting plate 31 at the location of the radiator, and the positioning frame 32 serves to restrict the position of the radiator.

[0039] The slide rail 33 is located above the fixed plate 10 and on both sides of the lifting plate 31. The two inner surfaces of the slide rail 33 are on the same plane as the inner surface of the reserved hole 221 formed in the top plate 22, so that the lifting plate 31 can enter the reserved hole 221 when it moves up and down. The slide rail 33 is connected to both ends of the lifting plate 31, and the slide rail 33 plays the role of restricting the movement direction of the lifting plate 31.

[0040] The telescopic tube 34 is fixedly mounted on the fixed plate 10 and is correspondingly set with the reserved hole 221. The telescopic tube 34 is composed of an inner tube and an outer tube. The bottom of the outer tube is fixedly connected to the fixed plate 10, the inner tube is located in the outer tube, and the top of the inner tube is fixedly connected to the lifting plate 31. The telescopic tube 34 serves to support the lifting plate 31 and the auxiliary slide rail 33 to limit the range of motion of the lifting plate 31.

[0041] A spring 35 is provided inside the telescopic tube 34. The bottom of the spring 35 contacts the fixed plate 10, and the top contacts the lifting plate 31. Under the cooperation of the fixed plate 10 and the lifting plate 31, the spring 35 is confined in the telescopic tube 34. When the spring 35 is extended, it can lift the lifting plate 31. At the same time, under the confinement of the telescopic tube 34, the lifting plate 31 is placed in the reserved hole 221. When the radiator is placed on the lifting plate 31, under the gravity of the radiator, the spring 35 contracts, the lifting plate 31 moves downward, and at this time the main body of the radiator enters the reserved hole 221. The top surface of the radiator body is lower than the top surface of the top plate 22, and the distance between the bottom surface of the radiator base and the bottom surface of the top plate 22 is sufficient to support the insertion of the plate 25.

[0042] The first electromagnet 36 is fixedly installed at the bottom of both ends of the lifting plate 31 that are not connected to the slide rail 33. The second electromagnet 37 is located below the first electromagnet 36. The first electromagnet 36 and the second electromagnet 37 have the same magnetic poles after being energized, so that the first electromagnet 36 and the second electromagnet 37 repel each other after being energized. A heightening bracket 38 is provided below the second electromagnet 37, which serves to support the second electromagnet 37.

[0043] The working principle of this utility model is as follows: A flattening fixture for heat-conducting copper pipes of a radiator. In the initial state, the support plate 25 is placed aside, and the telescopic tube 34 is extended under the elastic force of the spring 35, so that the lifting plate 31 is in the reserved hole 221. Electromagnets 36 and 37 are both in a de-energized state. The user places the radiator on the lifting plate 31, and the bottom of the radiator body cooperates with the positioning frame 32. The radiator body is restricted to a fixed position on the lifting plate 31 and cannot move horizontally. After the user places the radiator on the lifting plate 31, the spring 35 under the lifting plate 31 is compressed under the action of the radiator's own weight. The lifting plate 31 moves downward, causing the radiator to move downward. Subsequently, the weight of the radiator and the elastic force of the spring 35 are in a balanced state. At this time, the top surface of the radiator body is lower than the top surface of the top plate 22, and the distance between the bottom surface of the radiator base and the bottom surface of the top plate 22 is sufficient for the support plate 25 to be inserted. The user inserts the support plate 25, then energizes electromagnet 36 via a control switch while electromagnet 37 remains de-energized. Electromagnet 36 generates magnetic force to attract electromagnet 37, bringing them into contact. Simultaneously, spring 35 is compressed again, and telescopic tube 34 fully retracts. The lifting plate 31 is supported by the combination of the riser frame 38, electromagnets 36 and 37, and telescopic tube 34. At this point, the radiator is completely fixed. The radiator base is positioned by the limiting frame 23 and limiting post 24, and is also supported by the support plate 25. The main body of the radiator is fixed in a fixed position within the lifting plate 31 by the positioning frame 32. The rolling machine starts working, flattening the copper heat dissipation tubes above the radiator base. After the work is completed, the user controls the electromagnet 37 to be energized via the control switch. Electromagnets 36 and 37 repel each other, causing the lifting plate 31 to move upward under the elastic force of the spring 35. Under the repulsive force between the electromagnets 36 and 37, the lifting plate 31 drives the radiator upward, causing the main body of the radiator to protrude from the top surface of the top plate 22. The user can remove the radiator by picking up the main body. After removal, the electromagnets 36 and 37 are de-energized, and the lifting plate 31 returns to its initial position under the action of the spring 35, ready for the next round of work.

[0044] The rest of this embodiment is the same as that in Embodiment 1. Features not explained in this embodiment are explained using the methods in Embodiment 1, and will not be repeated here.

[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
