Description

Technical Field

[0001] This invention relates to the field of aluminum alloy manufacturing technology, and in particular to an aluminum stretching and forming equipment. Background Technology

[0002] In the processing of aluminum materials, stretching is a key step in controlling the quality of the formed aluminum material. In existing aluminum stretching methods, two clamps are usually used to clamp the two ends of the aluminum material respectively, and then the aluminum material is straightened by moving the two clamps in opposite directions. However, this method of stretching aluminum materials has the following defects: During the stretching process of slender aluminum materials, the tensile force on the aluminum material will be directly applied to its two ends. If the curvature of the middle of the aluminum material is greater than that of the two ends, two phenomena will occur: first, the tensile force is insufficient to straighten the middle of the aluminum material; second, the tensile force is too large, which will cause damage to the two ends of the aluminum material. This will affect the quality of the stretched aluminum material, or even cause the aluminum material to be damaged. Summary of the Invention

The second connecting frames are slidably connected to second outer cylinders. The second outer cylinders are threadedly connected to second threaded rods. The second threaded rods are rotatably connected to the adjacent second sliding frames. A second resistance spring is fixedly connected between the second outer cylinders and the adjacent second connecting frames. The elastic coefficient of the second resistance spring is greater than the elastic coefficient of the second elastic element.

[0006] Preferably, the first outer cylinder is fixedly connected to a first extrusion block, and the second outer cylinder is fixedly connected to a second extrusion block, wherein the first extrusion block is used to extrude the corresponding second extrusion block.

[0007] Preferably, airbags are fixed to the opposite sides of the first sliding frame symmetrically distributed on the same electric slide frame and the opposite sides of the second sliding frame symmetrically distributed on the same electric slide frame, and pressure sensors are provided inside the airbags.

[0008] Preferably, the airbag is provided with an inclined surface, and the spacing between the inclined surfaces of the airbags symmetrically distributed on the same electric slide gradually decreases from the point near the corresponding clamp to the point far away.

[0009] Preferably, both of the electric carriages are rotatably connected to rotating rings, and a winding wheel is rotatably connected to the electric carriage near the rotating ring.

[0014] Compared with the prior art, the present invention has the following beneficial effects: The present invention uses a first sliding frame to reciprocate straighten the aluminum material, while two clamps stretch the aluminum material. The first sliding frame straightens the aluminum material from the middle to both ends, ensuring the uniformity of deformation at all points during the stretching process. This reduces the probability of damage to the aluminum material due to excessive tension at both ends caused by bending in the middle, thus ensuring the quality of the stretched aluminum material. During the straightening of the vertical side of the aluminum material by the first sliding frame, the second sliding frame automatically straightens the horizontal side of the aluminum material, improving the quality of the formed aluminum material. During the stretching and straightening process, the straightened part of the aluminum material is gradually tightened by the connecting rope, thereby applying a holding force to the straightened aluminum material, reducing the probability of springback deformation after straightening, and thus improving the quality of the formed aluminum material.

Detailed Implementation

[0024] The following description is only a preferred embodiment of the present invention and does not limit the scope of protection of the present invention.

[0025] Example 1

[0026] An aluminum stretching and forming equipment, such as Figures 1-6 As shown, the device includes a base frame 1, with two clamps 2 symmetrically distributed on the left and right sides slidably connected to the base frame 1. A lifting platform 3 is installed below the base frame 1. The base frame 1 is provided with two electromagnetic slide rails symmetrically distributed front and rear. The electromagnetic slide rails symmetrically distributed on the base frame 1 are slidably connected to two electric slides 4 symmetrically distributed on the left and right sides. The electric slides 4 are fixedly connected to symmetrically distributed first connecting frames 7. The first connecting frames 7 are slidably connected to first sliding frames 8. A first elastic element 801 is fixedly connected between the first sliding frames 8 and the adjacent first connecting frames 7. The first connecting frames 7 are slidably connected to... A first outer cylinder 802 is connected, and a first threaded rod 803 is threadedly connected to the first outer cylinder 802. The first threaded rod 803 is rotatably connected to the adjacent first sliding frame 8. A first resistance spring 804 is fixed between the first outer cylinder 802 and the adjacent first connecting frame 7. The elastic coefficient of the first resistance spring 804 is greater than the elastic coefficient of the first elastic element 801. A trigger rod 9 is fixed to the first outer cylinder 802. Two limiting strips 10 are fixedly distributed symmetrically at the front and rear of the base frame 1. The limiting strips 10 are used to guide the corresponding trigger rods 9 on the two electric sliding frames 4.

[0027] Furthermore, the base frame 1 is equipped with a control terminal not shown in the figure, the clamp 2 is electrically connected to the control terminal, and both electromagnetic slide rails on the base frame 1 are electrically connected to the control terminal.

[0028] Furthermore, initially, the extruded aluminum material is passed between all the first sliding frames 8, so that the two ends of the aluminum material are clamped by two clamps 2. The lifting platform 3 is used to support the extruded aluminum material. After the two ends of the aluminum material are clamped by the two clamps 2, the lifting platform 3 retracts downward and disengages from the aluminum material.

[0029] Furthermore, during the process of the electric slide 4 driving the first connecting frame 7 to move left and right, the first connecting frame 7 drives the trigger rod 9 to move left and right through the first sliding frame 8, the first threaded rod 803 and the first outer cylinder 802. The opposing sides of the two limit bars 10 are both wavy. During the movement, the trigger rod 9 will move back and forth along the limit bar 10. The trigger rod 9 drives the first outer cylinder 802 to move back and forth, and the first resistance spring 804 deforms. The first outer cylinder 802 drives the first sliding frame 8 to move back and forth through the first threaded rod 803. During the movement, the first sliding frame 8 reciprocates to straighten the aluminum material. Accompanied by the two clamps 2 stretching the aluminum material, the first sliding frame 8 straightens the aluminum material from the middle to both ends, reducing the probability of damage to the aluminum material caused by excessive tension at both ends due to bending in the middle of the aluminum material. This ensures the quality of the aluminum material after stretching.

[0030] Furthermore, the first elastic element 801 is a compression spring.

[0031] Furthermore, by rotating the first threaded rod 803, the relative position of the first sliding frame 8 and the adjacent first outer cylinder 802 is adjusted, and the first elastic element 801 deforms (since the elastic coefficient of the first resistance spring 804 is greater than the elastic coefficient of the first elastic element 801, the relative position of the first outer cylinder 802 and the adjacent first connecting frame 7 remains unchanged at this time), so that the distance between the two adjacent first sliding frames 8 changes, thereby enabling the two first sliding frames 8 to straighten aluminum materials of different sizes and improve the applicability of this device.

[0032] like Figures 4-6 As shown, the electric slide 4 is fixedly connected to a second connecting frame 11 that is symmetrically distributed vertically. The second connecting frames 11 symmetrically distributed on the same electric slide 4 are all located between adjacent symmetrically distributed first connecting frames 7. The second connecting frame 11 is slidably connected to a second sliding frame 12. A second elastic element 1201 is fixedly connected between the second sliding frame 12 and the adjacent second connecting frame 11. The second connecting frame 11 is slidably connected to a second outer cylinder 1202. The second outer cylinder 1202 is threadedly connected to a second threaded rod 1203. The second threaded rod 1203 is rotatably connected to the adjacent second sliding frame 12. A second resistance spring 1204 is fixedly connected between the second outer cylinder 1202 and the adjacent second connecting frame 11. The elastic coefficient of the second resistance spring 1204 is greater than the elastic coefficient of the second elastic element 1201.

[0033] Furthermore, in this embodiment, the aluminum material is straightened by the first sliding frame 8 and the second sliding frame 12.

[0034] Furthermore, the second elastic element 1201 is a compression spring.

[0035] like Figures 4-6As shown, a first extrusion block 15 is fixedly connected to the first outer cylinder 802, and a second extrusion block 16 is fixedly connected to the second outer cylinder 1202. The first extrusion block 15 is used to extrude the corresponding second extrusion block 16.

[0036] Furthermore, both the first extrusion block 15 and the adjacent second extrusion block 16 have inclined surfaces on their opposing sides. Taking the first outer cylinder 802 on the front side and the corresponding second outer cylinder 1202 on the upper side as an example, when the first outer cylinder 802 on the front side moves backward, the first outer cylinder 802 presses the inclined surface of the second extrusion block 16 through the inclined surface of the first extrusion block 15, causing the second extrusion block 16 on the upper side to move downward. The second extrusion block 16 drives the second outer cylinder 1202 to move downward, the second resistance spring 1204 deforms, and the second outer cylinder 1202 drives the second sliding frame 12 to move downward through the second threaded rod 1203. That is, during the process of the first sliding frame 8 straightening the front and rear sides of the aluminum material, the second sliding frame 12 straightens the upper and lower surfaces of the aluminum material, thereby improving the quality of the aluminum material after forming.

[0037] Furthermore, by rotating the second threaded rod 1203 to adjust the height of the second sliding frame 12, the second elastic element 1201 deforms (since the elastic coefficient of the second resistance spring 1204 is greater than that of the second elastic element 1201, the relative position of the second outer cylinder 1202 and the adjacent second connecting frame 11 remains unchanged at this time), changing the distance between the two second sliding frames 12, so that the two second sliding frames 12 can straighten aluminum materials of different sizes, thus improving the applicability of this device.

[0038] The specific working principle is as follows:

[0039] When the operator needs to use this device to stretch aluminum material, the operator inserts the extruded aluminum material between all the first sliding frames 8 and all the second sliding frames 12. The lifting platform 3 supports the extruded aluminum material, and then clamps both ends of the aluminum material onto the two clamps 2 respectively. The lifting platform 3 is turned on through the control terminal, and the lifting platform 3 retracts downward and detaches from the aluminum material. The lifting platform 3 is turned off through the control terminal.

[0040] After the two ends of the aluminum material are clamped by the two clamps 2, the relative position of the first sliding frame 8 and the adjacent first outer cylinder 802 is adjusted by rotating the first threaded rod 803. The first elastic element 801 deforms (since the elastic coefficient of the first resistance spring 804 is greater than that of the first elastic element 801, the relative position of the first outer cylinder 802 and the adjacent first connecting frame 7 remains unchanged at this time), thus changing the distance between the two adjacent first sliding frames 8. By rotating the second threaded rod 1203 to adjust the height of the second sliding frame 12, the second elastic element 1201 deforms (since the elastic coefficient of the second resistance spring 1204 is greater than that of the second elastic element 1201, the relative position of the second outer cylinder 1202 and the adjacent second connecting frame 11 remains unchanged at this time), thus changing the distance between the two second sliding frames 12. This allows the two second sliding frames 12 to straighten aluminum materials of different sizes, improving the applicability of this device.

[0041] After the aluminum material is pressed by the first sliding frame 8 and the second sliding frame 12, the two electromagnetic slide rails and two clamps 2 on the base frame 1 are activated by the control terminal. The two clamps 2 move in opposite directions to stretch the aluminum material. At the same time, the two electric slides 4 move in opposite directions. During the movement of the two electric slides 4 in opposite directions, the electric slides 4 drive the first connecting frame 7 to move. The first connecting frame 7 drives the trigger rod 9 to move through the first sliding frame 8, the first threaded rod 803 and the first outer cylinder 802. The opposite sides of the two limit bars 10 are wavy. During the movement, the trigger rod 9 will move back and forth along the limit bars 10. The first outer cylinder 802 is moved back and forth by the trigger rod 9. The first outer cylinder 802 moves back and forth by the first threaded rod 803. The first resistance spring 804 deforms. The first sliding frame 8 straightens the aluminum material during the movement. The two clamps 2 stretch the aluminum material. The first sliding frame 8 straightens the aluminum material from the middle to both ends, ensuring the uniformity of deformation at all parts of the aluminum material during the stretching process. This reduces the probability of damage to the aluminum material caused by excessive tension at both ends due to bending in the middle of the aluminum material, thus ensuring the quality of the aluminum material after stretching.

[0042] During the forward and backward movement of the first sliding frame 8, taking the first outer cylinder 802 on the front side and the corresponding second outer cylinder 1202 on the upper side of one of the electric sliding frames 4 as an example, when the first outer cylinder 802 moves backward, the first outer cylinder 802 presses the inclined surface of the second extrusion block 16 through the inclined surface of the first extrusion block 15, causing the upper second extrusion block 16 to move downward. The second extrusion block 16 drives the second outer cylinder 1202 to move downward, the second resistance spring 1204 deforms, and the second outer cylinder 1202 drives the second sliding frame 12 to move downward through the second threaded rod 1203. That is, during the process of the first sliding frame 8 straightening the front and rear sides of the aluminum material, the second sliding frame 12 straightens the upper and lower surfaces of the aluminum material, thereby improving the quality of the aluminum material after forming.

[0043] After the two electric slides 4 move from the middle of the aluminum material to both ends, the clamps 2 stop moving, and the first slide 8 and the second slide 12 no longer straighten the aluminum material. Then, the two electric slides 4 move in opposite directions, and the electric slides 4 drive the parts on them to reset. The control terminal controls the clamps 2 to reset, and the two electromagnetic slides and the two clamps 2 on the base frame 1 are turned off through the control terminal. The lifting platform 3 is turned on through the control terminal. After the lifting platform 3 is reset, the lifting platform 3 is turned off through the control terminal. Finally, the first threaded rod 803 and the second threaded rod 1203 are reversed to reset the first slide 8 and the second slide 12. The first slide 8 and the second slide 12 no longer clamp the aluminum material, and the aluminum material is removed from the clamps 2 and collected.

[0044] Example 2

[0045] Based on Example 1, such as Figure 5 and Figure 6 As shown, airbags 17 are fixed to the opposite sides of the first sliding frame 8 and the second sliding frame 12 symmetrically distributed on the same electric slide 4. A pressure sensor is installed inside the airbag 17. The airbag 17 is provided with an inclined surface. The spacing between the inclined surfaces of the airbags 17 symmetrically distributed on the same electric slide 4 gradually decreases from the point near the corresponding clamp 2 to the point far away.

[0046] Furthermore, the pressure sensor inside the airbag 17 is electrically connected to the control terminal. In the above embodiment, the aluminum material is straightened by the first sliding frame 8 and the second sliding frame 12. In this embodiment, different types of aluminum materials are pressed by the airbag 17. During the process of the aluminum material being compressed, the deformation of the airbags 17 symmetrically distributed on the same electric sliding frame 4 is the same, so as to improve the applicability of this device. During the process of the airbag 17 straightening the aluminum material, if the difference in the values ​​of the pressure sensors in all the airbags 17 is within the threshold, the aluminum material is qualified. If the aluminum material is unqualified due to a large degree of bending, the difference in the values ​​of the pressure sensors in all the airbags 17 exceeds the threshold (for example, if the front side of the aluminum material is concave, the pressure value of the pressure sensor in the front airbag 17 that moves to the concave part is abnormal and differs from the value of the pressure sensor in the corresponding rear airbag 17). This reminds the operator that the aluminum material is unqualified and the aluminum material is reworked in time, so as to reduce the subsequent inspection steps of the aluminum material and improve the efficiency of aluminum material production.

[0047] Example 3

[0048] Based on Example 2, such as Figures 1-3 and Figure 7As shown, both electric carriages 4 are rotatably connected to rotating rings 18. The two rotating rings 18 are located between all the first connecting frames 7 on different electric carriages 4. The electric carriages 4 are rotatably connected to winding wheels 19 near the rotating rings 18. The two winding wheels 19 are wound together with a connecting rope 20, which passes through the two rotating rings 18.

[0049] like Figure 7 As shown, the winding wheel 19 is slidably connected to a sliding member 21, and a third elastic member 2101 is fixedly connected between the sliding member 21 and the adjacent rotating ring 18. The sliding member 21 is rotatably connected to a rotating wheel 22, which is used to compress the connecting rope 20. The connecting rope 20 is used to limit the two rotating wheels 22. The two rotating rings 18 rotate in opposite directions, and the two rotating wheels 22 are located on both sides of the central axis of the rotating ring 18.

[0050] like Figure 4 , Figure 7 and Figure 8 As shown, the electric carriage 4 is equipped with a gearbox 23. The input shaft of the gearbox 23 is fixedly connected to the adjacent take-up reel 19. The output shaft of the gearbox 23 is driven by a gear set to the adjacent rotating ring 18. A spring 24 is fixedly connected between the take-up reel 19 and the adjacent gearbox 23.

[0051] Furthermore, the connecting rope 20 is non-elastic. The connecting rope 20 is used to bind the aluminum material, thereby applying a holding force to the straightened aluminum material, reducing the probability of springback deformation after straightening, and thus improving the quality of the formed aluminum material.

[0052] Furthermore, the third elastic element 2101 is a compression spring.

[0053] Furthermore, the transmission 23 is electrically connected to the control terminal.

[0054] Furthermore, initially, the two rotating rings 18 are in contact, and the connecting rope 20 is wound around the two take-up wheels 19. As the two electric carriages 4 move in opposite directions, the two take-up wheels 19 move in opposite directions, and the two rotating rings 18 move in opposite directions, causing the connecting rope 20 to be taut. As the two take-up wheels 19 move in opposite directions, the connecting rope 20 is released, the take-up wheels 19 rotate, and the spring 24 gradually accumulates power. The take-up wheels 19 drive the adjacent rotating rings 18 through the gearbox 23 and the gear set. The two rotating rings 18 rotate in opposite directions, and the two connecting ropes 20 together wind the connecting rope 20 around the aluminum material.

[0055] Furthermore, by adjusting the transmission ratio of the gearbox 23 through the control terminal, the transmission ratio of the winding wheel 19 and the rotating ring 18 can be adjusted, that is, the ratio of the release speed of the connecting rope 20 to the winding speed of the connecting rope 20 on the aluminum material can be adjusted, so that the connecting rope 20 can be tightly wound on aluminum materials of different sizes, thereby improving the applicability of this device.

[0056] Furthermore, initially, the connecting rope 20 presses against the two rotating wheels 22, and the third elastic element 2101 is in a compressed state. When the winding wheel 19 releases the connecting rope 20, the third elastic element 2101 pops out, and the sliding element 21 presses the connecting rope 20 against the aluminum material through the rotating wheels 22. With the movement and rotation of the rotating ring 18, the rotating ring 18 drives the rotating wheel 22 to move and rotate through the sliding element 21. The rotating wheel 22 presses the connecting rope against the aluminum material, ensuring that the connecting rope 20 binds the aluminum material with sufficient force, reducing the probability of springback deformation after the aluminum material is straightened, thereby improving the quality of the straightened aluminum material.

[0057] When the two electric carriages 4 move to reset in opposite directions, the spring 24 gradually resets, causing the winding wheel 19 to reset and wind up the connecting rope 20. The winding wheel 19 drives the adjacent rotating ring 18 through the gearbox 23 and gear set, causing the rotating ring 18 to reverse and reset.

[0058] Those skilled in the art should understand that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by equivalent substitution or equivalent transformation fall within the protection scope of the present invention.
