Description

Technical Field

[0001] The invention relates to the technical field of aluminum material processing, and more specifically to an aluminum material straightening device for producing heat sinks. Background Art

[0002] A heat sink is a heat dissipation device specially designed for heat-prone electronic components in electrical appliances. Its main function is to effectively transfer the heat generated by the components to the heat sink and dissipate it into the surrounding air through the heat sink, thereby reducing the temperature inside the appliance. Heat sinks are mostly made of metal materials such as aluminum alloy, brass or bronze, which have excellent thermal conductivity. Among these materials, silver has the best thermal conductivity, but the cost is too high; copper also has good thermal conductivity, but is more expensive; and aluminum alloy is widely used because of its moderate thermal conductivity, low price and good processability.

[0003] Aluminum is easy to deform, and it is easy to bend or twist during production, storage and transportation. It is necessary to use a straightening machine to straighten the aluminum before processing to ensure the accuracy and efficiency of subsequent processing. Most of the existing straightening machines include a frame and two fixed clamps. A roller is arranged on the frame to support the aluminum. A moving mechanism is arranged on one side of the frame, one of the fixed clamps is arranged at the movable end of the moving mechanism, and the other fixed clamp is fixed on the other side of the frame. The two clamps clamp the two ends of the aluminum respectively, and the corresponding fixed clamp is driven to move by the movement of the movable end of the moving mechanism, thereby straightening the aluminum.

[0004] The existing aluminum materials used in the production of heat sinks usually have tube types and plate types, among which the raw materials of the tube type heat sink include aluminum tubes. Currently, both plate type aluminum materials and tube type aluminum materials are straightened by straightening machines, and the straightening machines have low functionality. Most of the fixing clamps on the current straightening machines are more suitable for clamping plate type aluminum materials. When clamping tube type aluminum materials, the two ends of the tube type aluminum materials will be flattened. After straightening, the flattened parts of the tube type aluminum materials need to be cut off, which not only increases the cutting frequency during the pretreatment of the tube type aluminum materials used in the production of heat sinks, reduces the pretreatment efficiency of the tube type aluminum materials, but also causes waste of the tube type aluminum materials, resulting in high production costs of the heat sinks. In view of this, we propose an aluminum straightening device for the production of heat sinks. Summary of the invention

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. The present invention fixes the two ends of the tubular aluminum material by designing two fixing mechanism structures, which is convenient for straightening the tubular aluminum material. The linkage part is controlled by the adjusting component, so that the friction component A is in close contact with the circular plate and the worm ring. The friction force causes the circular plate to rotate simultaneously when the worm ring rotates, so that the forward guide groove and the reverse guide groove rotate simultaneously, causing the tensioning component to slide on the centripetal slide groove, and the eccentrically connected clamping component slides on the eccentric slide groove, and the tensioning component and the clamping component move in opposite directions, so that the gap between several clamping components and several tensioning components constitutes a fixed cavity size change, and the tubular aluminum material is clamped when it is reduced. The corresponding tensioning component and the clamping component support each other to prevent the end of the tubular aluminum material from being clamped and flattened during the straightening process. After the two fixing mechanisms fix the two ends of the tubular aluminum material, the hydraulic cylinder is controlled by the external control mechanism to straighten the tubular aluminum material, thereby reducing the cutting frequency during the pretreatment of the tubular aluminum material and reducing the waste of the tubular aluminum material, thereby solving the technical problems of low pretreatment efficiency of tubular aluminum material for heat sink production and high production cost of heat sink.

[0024] 2. The present invention also designs a rotating component structure. The worm gear structure causes the worm to rotate and drive the worm ring to rotate, which has a self-locking effect, so that when the gaps between a number of clamping components and a number of tensioning components form a fixed cavity to fix the tubular aluminum material, no additional fixing structure is required, making the structure compact. The worm gear structure has a deceleration effect, which facilitates the adjustment of the center position of the fixed cavity formed by the gaps between a number of clamping components and a number of tensioning components, thereby improving the accuracy of the adjustment, thereby reducing the trial and error time, and further improving the pretreatment efficiency of the tubular aluminum material for the production of hot plates, saving time costs.

[0025] 3. The present invention also designs the forward guide groove and the reverse guide groove to be arc-shaped structures, and the reverse guide groove is adapted to the forward guide groove, so that when the reverse guide groove and the forward guide groove rotate together, the sliding distance of the centripetal slider on the centripetal slide groove is equal to the sliding distance of the eccentric slider on the eccentric slide groove, which further facilitates the adjustment of the center position of the fixed cavity formed by the gap between a plurality of clamping assemblies and a plurality of tensioning assemblies.

[0026] 4. The present invention arranges the friction assembly A so that when the friction ring A is in close contact with the friction cavity, the circular plate and the volute ring rotate to form a relatively fixed structure. At this time, the volute ring rotates and the circular plate rotates synchronously with it. When the friction ring A is separated from the friction cavity, the circular plate does not rotate synchronously when the volute ring rotates. The volute ring can be rotated according to the size of the tubular aluminum material, and then the gaps between the plurality of clamping assemblies and the plurality of tensioning assemblies are adjusted to form the center position of the fixed cavity. The present invention further arranges the friction ring A so that the cross-section of the friction ring A is arranged to be a trapezoidal structure, thereby increasing the contact area between the friction ring A and the friction cavity and improving the friction fixing effect of the friction ring A. The friction end surface of the friction ring A is arranged to be wavy, thereby further increasing the contact area between the friction ring A and the friction cavity and further improving the friction fixing effect of the friction ring A. The friction ring A of this shape is more convenient to "insert" into the friction cavity, which is convenient for adjusting the friction assembly A and ensures the stability of the synchronous rotation of the volute ring and the circular plate.

[0027] 5. The present invention arranges the friction assembly A and the friction assembly B so that when the friction assembly A is disengaged, the friction ring B can be fixed by friction with the side wall of the U-shaped seat, so that the coupling shaft and the circular plate cannot rotate. At this time, the center position of the fixed cavity is more accurate and easy to adjust by adjusting the gaps between the clamping assemblies and the tensioning assemblies.

[0028] 6. The present invention arranges the friction assembly A, the friction assembly B and the linkage part, and further designs the displacement guide groove A and the displacement guide groove B, so that when the gaps between the plurality of clamping assemblies and the plurality of tensioning assemblies form the center position of the fixed cavity, the gear ring rotates, the entire linkage part rotates, the ball block A first moves in the arc groove A, the position of the friction assembly A remains stationary, and at the same time, the ball block B moves in the partial thread groove B, driving the friction assembly B to slide toward the side wall of the U-shaped seat. When the ball block A moves to the tail end of the arc groove A, the ball block B moves to the tail end of the partial thread groove B, and the friction ring B and the U-shaped seat are aligned. The seat side wall is fixed by friction, the gear ring continues to rotate, the ball block A enters part of the thread groove A and moves, the friction component A is disengaged from the friction cavity, and the ball block B enters the arc groove B and moves, driving the friction component B to remain stationary toward the U-shaped seat position, so that the connecting shaft and the circular plate cannot rotate. At this time, the motor is controlled to rotate by an external control mechanism, causing the worm ring to rotate. The gaps between several clamping components and several tensioning components constitute the change of the center position of the fixed cavity. The worm gear structure has a deceleration effect, which further improves the accuracy of the adjustment, and the adjustment is convenient and accurate. When adjusted to the straightened state, the reverse operation can be performed.

[0029] Moreover, the arc groove A and the arc groove B have a limiting effect on the ball block A and the ball block B respectively, preventing the friction ring B and the friction ring A from moving due to elastic force, thereby ensuring the friction fixing effect of the friction ring B and the friction ring A.

[0068] In an embodiment of the present invention, a sliding sleeve A731 is rotatably connected to one end of the friction chamber with an installation swivel A733, an embedding groove A734 is provided on the installation swivel A733, a friction ring A735 is embedded in the embedding groove A734, and the friction ring A735 is frictionally matched with the friction chamber; the cross-section of the friction end of the friction ring A735 is a trapezoidal structure, and the surface of the friction end of the friction ring A735 is wavy, and the friction chamber is adapted to the friction ring A735. The present invention arranges the friction assembly A73 so that when the friction ring A735 is in close contact with the friction cavity, the circular plate 7 and the volute ring 8 rotate to form a relatively fixed structure. At this time, the volute ring 8 rotates the circular plate 7 and rotates synchronously with it. When the friction ring A735 is disengaged from the friction cavity, the circular plate 7 does not rotate synchronously when the volute ring 8 rotates. The volute ring 8 can be rotated according to the size of the tubular aluminum material, and then the gaps between the plurality of clamping assemblies 6 and the plurality of tensioning assemblies 5 are adjusted to form the center position of the fixed cavity. In addition, the present invention further arranges the friction ring A735 so that the cross-section of the friction ring A735 is arranged to be a trapezoidal structure, thereby increasing the contact area between the friction ring A735 and the friction cavity and improving the friction fixing effect of the friction ring A735. The friction end surface of the friction ring A735 is arranged to be wavy, thereby further increasing the contact area between the friction ring A735 and the friction cavity and further improving the friction fixing effect of the friction ring A735. The friction ring A735 of this shape is easier to "insert" into the friction cavity, facilitates the adjustment of the friction assembly A73, and ensures the stability of the synchronous rotation of the volute ring 8 and the circular plate 7.

[0069] The friction component B74 is frictionally matched with the side wall of the U-shaped seat 3. The friction component B74 includes a sliding sleeve B741. The sliding sleeve B741 is sleeved on the side of the connecting shaft 72 away from the circular plate 7. A number of sliding bars B742 are fixedly arranged on the inner edge surface of the sliding sleeve B741 corresponding to the number of the limiting sliding grooves B722. The sliding bars B742 are slidably connected with the limiting sliding grooves B722. The outer edge surface of the sliding sleeve B741 is linearly and evenly spaced. A number of displacement guide grooves B740 are provided. The end of the sliding sleeve B741 away from the friction chamber is rotatably connected with a mounting swivel B743. The mounting swivel B743 is provided with an embedded groove B744. A friction ring B745 is embedded in the embedded groove B744. The friction ring B745 is frictionally matched with the side wall of the U-shaped seat 3.

[0070] The displacement guide groove B740 includes an arc groove B746, and the arc groove B746 is connected to a part of the thread groove B747 at one end away from the friction ring B745. The present invention arranges the friction assembly A73 and the friction assembly B744 so that when the friction assembly A73 is disengaged, the friction ring B745 can be fixed by friction with the side wall of the U-shaped seat 3, so that the connecting shaft 72 and the circular plate 7 cannot rotate. At this time, the center position of the fixed cavity is more accurately formed by adjusting the gap between the clamping assemblies 6 and the tensioning assemblies 5, which is convenient for adjustment and more convenient for clamping different types of tubular aluminum materials.

[0071] The friction component A73 is movably connected with the friction component B74 through a linkage part 75, and the linkage part 75 includes a gear ring 751, which is rotatably arranged on the connecting shaft 72 relative to the gap position of the limiting slide groove A721 and the limiting slide groove B722. A linkage sleeve A752 and a linkage sleeve B753 are respectively fixed at both ends of the gear ring 751, and a plurality of ball blocks A754 are fixed on the linkage sleeve A752 relative to the plurality of arc grooves A737. The ball block A754 is movably connected with the arc groove A737, and the ball block A754 is movably matched with a part of the thread groove A736. A plurality of ball blocks B755 are fixed on the linkage sleeve B753 relative to the plurality of partial thread grooves B747, and the ball block B755 is movably connected with a part of the thread groove B747, and the ball block B755 is movably matched with the arc groove B746. The present invention arranges the friction assembly A73, the friction assembly B74 and the linkage part 75, and further designs the displacement guide groove A730 and the displacement guide groove B740, so that when the gaps between the plurality of clamping assemblies 6 and the plurality of tensioning assemblies 5 form the center position of the fixed cavity, the gear ring 751 rotates, the entire linkage part 75 rotates, the ball block A754 first moves in the arc groove A737, the position of the friction assembly A73 remains stationary, and at the same time, the ball block B755 moves in the partial thread groove B747, driving the friction assembly B74 to slide toward the side wall of the U-shaped seat 3. When the ball block A754 moves to the tail end of the arc groove A737, the ball block B755 moves to the tail end of the partial thread groove B747. The friction ring B745 is fixed by friction with the side wall of the U-shaped seat 3, the gear ring 751 continues to rotate, the ball block A754 enters the partial thread groove A736 and moves, the friction component A73 disengages from the friction cavity, and at the same time the ball block B755 enters the arc groove B746 and moves, driving the friction component B74 to remain stationary toward the U-shaped seat 3, so that the connecting shaft 72 and the circular plate 7 cannot rotate. At this time, the motor 92 is controlled to rotate by an external control mechanism, causing the worm ring 8 to rotate, and the gaps between the clamping components 6 and the tensioning components 5 constitute the change in the center position of the fixed cavity. The worm gear structure has a deceleration effect, which further improves the accuracy of the adjustment, and the adjustment is convenient and accurate; when adjusted to the straightened state, the reverse operation can be performed.

[0072] Moreover, the arc groove A737 and the arc groove B746 have a limiting effect on the ball block A754 and the ball block B755 respectively, preventing the friction ring B745 and the friction ring A735 from moving due to elastic force, thereby ensuring the friction fixing effect of the friction ring B745 and the friction ring A735.

[0073] In the embodiment of the present invention, an adjustment assembly 10 is arranged on the bottom plate of the U-shaped seat 3, and the movable end of the adjustment assembly 10 is meshed and connected with the linkage part 75.

The ball block A754 first moves in the arc groove A737, and the position of the friction component A73 remains stationary. At the same time, the ball block B755 moves in the partial thread groove B747, driving the friction component B74 to slide toward the side wall of the U-shaped seat 3. When the ball block A754 moves to the tail end of the arc groove A737, the ball block B755 moves to the tail end of the partial thread groove B747, and the friction ring B74 5 is fixed by friction with the side wall of the U-shaped seat 3, the gear ring 751 continues to rotate, the ball block A754 enters the partial thread groove A736 and moves, the friction component A73 is separated from the friction cavity, and the ball block B755 enters the arc groove B746 and moves, driving the friction component B74 to remain stationary toward the U-shaped seat 3, so that the connecting shaft 72 and the circular plate 7 cannot rotate. At this time, the motor 92 is controlled to rotate by the external control mechanism, causing the worm ring 8 to rotate, and the gaps between the clamping components 6 and the tensioning components 5 constitute the change of the center position of the fixed cavity. The worm gear structure has a deceleration effect, which further improves the accuracy of the adjustment. The adjustment is convenient and accurate. When the reverse operation is adjusted to the straightened state;

[0076] Put the tubular aluminum material for heat sink production into the gap between the clamping components 6 and the tensioning components 5, and control the motor 92 to rotate through the external control mechanism, so that the worm ring 8 rotates to drive the worm ring 8 to rotate, and the reverse guide groove 81 rotates synchronously, so that the movable rod B64 moves in the reverse guide groove 81, and the eccentric slider 61 slides in the eccentric slide groove 42, so that the clamping block 62 and the rubber block B63 move at the same time, and the rubber block B63 and the rubber block A53 move in an opposite structure, so that the clamping cavity formed by the rubber block B63 on the clamping blocks 62 expands and contracts;

[0077] The circular plate 7 and the connecting shaft 72 rotate synchronously, and the forward guide groove 71 rotates accordingly, causing the movable rod A54 to move along the forward guide groove 71, the centripetal slider 51 slides along the centripetal slide groove 41, and the tensioning block 52 and the rubber block A53 move synchronously, causing the tensioning cavity formed by the rubber blocks A53 to expand and contract, and the gap between the clamping assembly 6 and the tensioning assemblies 5 constitutes a change in the size of the fixed cavity, fixing the end of the tubular aluminum material, and treating the other end of the tubular aluminum material for heat sink production in the same way;
