Description

Technical Field

[0001] The present invention relates to the technical field of metal cutting machine tools, in particular to an aluminum material shearing device for furniture production. Background Art

[0002] Aluminum furniture is a type of furniture made primarily of lightweight, corrosion-resistant aluminum profiles and is widely used in modern homes. During the production process, the aluminum profile must first be cut to the appropriate length, then spliced, and finally welded and assembled. When shearing the aluminum profile, a shearing device clamps the profile to secure its position and ensure cutting accuracy. When the cutter shears the aluminum profile, the shearing force generated causes the aluminum profile to be strongly squeezed. Due to the high ductility of aluminum, bending and deformation easily occur at the cut, resulting in burrs or microcracks on the edges of the aluminum profile. This is more pronounced when shearing thin aluminum profiles. The deformation generated during this cutting process not only destroys the smoothness of the material but also increases the difficulty of subsequent processing. This not only reduces production efficiency but may also affect the structural strength and aesthetics of the furniture. Summary of the Invention

[0020] The existing aluminum shearing device can only fix the shape of the aluminum during the shearing process, but cannot relieve the extrusion force on the aluminum during the cutting process, causing the cut part of the aluminum to be easily bent and deformed, affecting the subsequent normal processing of the aluminum.

[0021] Example 1: Aluminum shearing equipment for furniture production, such as Figure 1-Figure 7 and Figure 9 As shown, it includes a shearing table 1, a lifting platform 2 is installed on the shearing table 1, a shearing module is arranged in the shearing table 1, an electric push rod 3 is fixed on the lifting platform 2, the telescopic end of the electric push rod 3 is fixedly connected to a lifting frame 4, the lifting frame 4 is slidingly connected to the lifting platform 2, the lifting frame 4 is slidingly connected to a symmetrically distributed connecting frame 5, the connecting frame 5 is slidingly connected to a positioning plate 6, a tension spring 7 is fixed between the positioning plate 6 and the adjacent connecting frame 5, the positioning plate 6 is installed with a support plate 8, the support plate 8 is used to limit the minimum distance between the positioning plate 6 and the shearing table 1, three connecting shells 9 are arranged on the connecting frame 5, a connecting pipe 10 is slidingly and rotatably connected in the connecting shell 9, a suction cup 11 is hinged at the lower end of the connecting pipe 10, and the connecting pipe 10 is connected to the adjacent connecting shell 9 and the adjacent suction cup 11.

[0022] The above invention provides a method for applying reverse pulling force to the surface of aluminum material from the outside during the shearing process of aluminum material, thereby offsetting part of the shearing force on the aluminum material and reducing the degree of deformation of the aluminum material; a conveying module is provided on the left side of the shearing table 1, and the conveying module is used to convey the aluminum material from left to right. The shearing module in the shearing table 1 is an existing disc cutter. The conveying module and the shearing module on the shearing table 1 are both existing devices, and their specific structure and usage method are no longer described in detail. The lifting platform 2 is located at the rear of the upper side of the shearing table 1, and the electric push rod 3 is located at the front of the upper side of the lifting platform 2. The telescopic end of the electric push rod 3 passes through the lifting platform 2, and the lifting frame 4 is composed of a rectangular plate and two round rods The two round rods of the lifting frame 4 are slidably connected to the lifting platform 2 to guide the movement of the lifting frame 4 and improve the stability of the lifting frame 4 during movement. The lower side of the lifting frame 4 is slidably connected with two connecting frames 5 symmetrically distributed on the left and right. The positions of the connecting frames 5 and the lifting frame 4 are fixed by an existing locking device. When shearing aluminum materials of different widths, the relative positions of the connecting frames 5 and the lifting frame 4 are adjusted so that the connecting frames 5 are symmetrical with respect to the center line of the aluminum material. The positioning plate 6 is located at the lower part of the connecting frame 5. The positioning plate 6 is used to fit the upper side of the aluminum material. The tension spring 7 is used to push the positioning plate 6 to move downward and reset relative to the connecting frame 5.

[0023] The support plate 8 is located at the front of the lower side of the positioning plate 6. The support plate 8 is used to limit the downward movement distance of the positioning plate 6 to prevent the positioning plate 6 from over-extruding the aluminum material and causing its deformation. The lower part of the rear side of the support plate 8 is provided with an inclined surface, which is used to facilitate the support plate 8 to position the aluminum material during the downward movement of the support plate 8. In actual use, the downward movement distance of the positioning plate 6 can be limited by replacing different support plates 8. In this article, a connecting frame 5 has three connecting shells 9, and the connecting shell 9 is externally connected to an air pump. The air pump is used to extract the gas in the suction cup 11 through the connecting shell 9 and the connecting pipe 10, so that the suction cup 11 generates negative pressure suction on the adjacent area where the aluminum material is sheared, thereby providing an upward pulling force for the aluminum material and reducing the deformation of the upper part of the aluminum material during the cutting process. Taking the parts on the left connecting frame 5 as an example, the three connecting shells 9 on it A connecting shell 9 located in the middle is closer to the cutting edge of the aluminum material. The number and position of the connecting shells 9 can be adjusted according to actual conditions. In this section, the connecting shell 9 does not rotate relative to the adjacent connecting frame 5. The connecting tube 10 is composed of a circular plate, a round rod and a hemispherical portion, and the suction cup 11 rotates on the hemispherical portion of the connecting tube 10. The hemispherical portion of the connecting tube 10 is provided with a protrusion, which is used to limit the rotation direction of the suction cup 11 relative to the adjacent connecting tube 10. The rotation axis of the suction cup 11 passes through the center of the upper hemispherical portion of the connecting tube 10, and the upper part of the suction cup 11 fits with the hemispherical portion of the connecting tube 10 to ensure the seal between the two. Three through holes are provided on the positioning plate 6, and the three suction cups 11 on the connecting frame 5 are respectively located in adjacent through holes on the positioning plate 6. Initially, the lower side surfaces of the three suction cups 11 are flush with the lower side surface of the positioning plate 6.

[0024] Workflow: When it is necessary to shear the aluminum material, the staff will place the aluminum material to be cut on the conveying module of the shearing table 1, and then the staff will adjust the position of the connecting frame 5 and replace the support plate 8 of the corresponding height, so as to control the downward movement distance of the positioning plate 6 and make the connecting frame 5 symmetrical about the center line of the aluminum material. After that, the staff will start the conveying module, and after the conveying module drives the aluminum material to move to the right by a specified distance, the staff will close the conveying module on the shearing table 1, and then the staff will start the electric push rod 3, and the telescopic end of the electric push rod 3 will extend and drive the lifting frame 4 to move downward, and the lifting frame 4 will drive the two connecting frames 5 and the parts thereon to move downward synchronously, and the connecting frame 5 will drive the positioning plate 6 to move through the tension spring 7, and the positioning plate 6 will drive the support plate 8 to move downward close to the upper side of the shearing table 1. When After the support plate 8 contacts the front side of the aluminum material, the front and rear sides of the aluminum material are fixed. As the positioning plate 6 continues to move downward, when the support plate 8 contacts the upper side of the shearing table 1, the positioning plate 6 stops moving. At this time, the suction cup 11 contacts the aluminum material, and the connecting frame 5 continues to move downward through the connecting shell 9 and drives the connecting tube 10. The tension spring 7 stretches and accumulates force, causing the suction cup 11 to deform and fit the aluminum material. Until the electric push rod 3 is fully extended, the connecting frame 5 stops moving downward, and the suction cup 11 fits the aluminum material. The staff starts the air pump, and the air pump extracts the gas in the connecting shell 9, the connecting tube 10 and the suction cup 11, so that the suction cup 11 produces an upward pulling force on the aluminum material, thereby reducing the downward deformation of the aluminum material during the cutting process. After that, the staff starts the cutting module on the shearing table 1 to cut the aluminum material.

[0025] Further, such as Figure 5-Figure 7 and Figure 9 As shown, a guide block 12 is fixed in the connecting shell 9, a first spring 13 is provided between the connecting shell 9 and the adjacent connecting pipe 10, a guide groove 14 is provided on the connecting pipe 10, the guide block 12 slides in the adjacent guide groove 14, and a water spray module is provided on the suction cup 11 for spraying water onto the surface of the aluminum material.

[0026] The above scheme provides a way to increase the adsorption force between the suction cup 11 and the aluminum material; taking the moving direction of the left connecting frame 5 and the parts thereon as an example, a water spray module is provided on the suction cup 11. In the process of the connecting frame 5 driving the parts thereon to move downward, when the suction cup 11 approaches the upper side of the aluminum material, the water spray module sprays water between the upper surface of the aluminum material and the suction cup 11, and after the suction cup 11 contacts the aluminum material, the gap between the two is filled with water, thereby increasing the sealing between the suction cup 11 and the aluminum material, ensuring that the suction cup 11 can exert a force on the adjacent position of the aluminum material, the guide block 12 is located at the lower part of the adjacent connecting shell 9, the first spring 13 is used to push the adjacent connecting pipe 10 to move downward and reset relative to the adjacent connecting shell 9, the guide groove 14 consists of an arc groove and two vertical grooves, wherein the arc groove of the guide groove 14 is located between the two vertical grooves thereon, and the arc groove of the guide groove 14 guides the adjacent connecting pipe 10 to rotate counterclockwise relative to the connecting shell 9 through the guide block 12 ( Figure 6 , looking from top to bottom), apply water to the suction cup 11 during the process of attaching it to the upper side of the aluminum material, ensuring that the water can completely fill the gap between the suction cup 11 and the aluminum material.

[0027] After the suction cup 11 contacts the aluminum material, as the connecting frame 5 continues to drive the parts on it to move downward, the connecting shell 9 pushes the connecting tube 10 downward through the first spring 13, so that the connecting tube 10 squeezes the suction cup 11 downward, and then the suction cup 11 gradually fits the surface of the aluminum material. During this process, the first spring 13 is gradually compressed, the connecting shell 9 moves downward relative to the connecting tube 10, and the guide block 12 moves downward along the vertical groove on the upper side of the guide groove 14 until the guide block 12 enters the arc groove of the guide groove 14. The guide block 12 squeezes the arc groove of the guide groove 14, so that the connecting tube 10 drives the suction cup 11 to rotate clockwise ( Figure 6 , looking from top to bottom) apply water, during this process the suction cup 11 continues to be compressed and deformed, when the guide block 12 enters the vertical groove on the lower side of the guide groove 14, the connecting pipe 10 and its parts stop rotating, until the connecting frame 5 stops moving downward, the suction cup 11 stops deforming and fits.

[0028] Example 2: Based on Example 1, Figure 4-Figure 6 and Figure 9 As shown, the connecting shell 9 is fixed with symmetrically distributed limiting rods 19, and the connecting frame 5 is provided with a second slide groove 18 and a symmetrically distributed first slide groove 17. The second slide groove 18 is located between the symmetrically distributed first slide grooves 17. All the connecting shells 9 on the same connecting frame 5 are respectively located in adjacent first slide grooves 17 and adjacent second slide grooves 18. The three limiting rods 19 on the same connecting frame 5 are respectively located in adjacent first slide grooves 17 and adjacent second slide grooves 18 to slide and rotate.

[0029] Further, such as Figure 4-Figure 6 and Figure 9As shown, an extrusion frame 15 is slidably connected to the connecting frame 5. The extrusion frame 15 is used to push all the connecting shells 9 on the adjacent connecting frames 5 to deflect. An electromagnet 16 is fixed to the extrusion frame 15 and is used to provide power for the movement of the extrusion frame 15.

[0030] Further, such as Figure 5 and Figure 8 As shown, the extension line of the first sliding groove 17 and the extension line of the second sliding groove 18 on the same connecting frame 5 are perpendicular to each other.

[0031] The above solution provides a way to adjust the angle of the connecting shell 9; Figure 2 Taking the position of the parts on the left connecting frame 5 as an example, a connecting shell 9 is fixed with two symmetrically distributed limit rods 19. In this article, a connecting frame 5 is provided with two first slide grooves 17 symmetrically distributed front and back. The first slide groove 17 is in the front and back direction, and the second slide groove 18 is in the left and right direction. The angle between the first slide groove 17 and the second slide groove 18 is 90°, and the angle between the two can be adjusted according to actual conditions. Initially, the connecting shell 9 is vertically upward, and the connecting shell 9 is located on the inner side of the adjacent first slide groove 17 (second slide groove 18). The limit rod 19 is a round rod with a hemispherical head, which is used to swing the connecting shell 9 relative to the first slide groove 17 (second slide groove 18) when the connecting shell 9 moves along the first slide groove 17 (second slide groove 18).

[0032] Herein, the connecting shell 9 in the first slide groove 17 can only move and swing in the front and back directions, and the connecting shell 9 in the second slide groove 18 can only move and swing in the left and right directions. The front and rear parts of the left side of the extrusion frame 15 are both provided with inclined surfaces, and the distance between the two inclined surfaces on the extrusion frame 15 gradually increases from left to right. When the extrusion frame 15 moves to the left, the two inclined surfaces on the extrusion frame 15 respectively push the connecting shells 9 on the front and rear sides to move in the front and rear directions, and at the same time, the middle part of the extrusion frame 15 pushes the middle connecting shell 9 to move to the left, thereby adjusting the direction between the connecting pipe 10 and the suction cup 11, and changing the direction of the force exerted by the suction cup 11 on the aluminum material. After the direction of the connecting pipe 10 and the suction cup 11 is adjusted, the suction cups 11 on the front and rear sides respectively generate a front and rear force on the upper side of the aluminum material, so that The suction cups 11 on the front and rear sides respectively produce a tendency for the adjacent areas of the aluminum material to move in the front and rear directions, thereby causing the upper side of the aluminum material to be stretched. The middle suction cup 11 produces a tendency for the aluminum material to move to the left, exerting a force on the aluminum material away from the cutter, reducing the extrusion force between the aluminum material and the cutter during the cutting process, thereby reducing the deformation amplitude of the aluminum material. The electromagnet 16 is located on the right side of the connecting frame 5, and the magnetic poles of the two electromagnets 16 on the facing sides are the same. The position during use can be adjusted according to actual conditions. After the connecting frame 5 stops moving downward and the suction cup 11 is in contact with the aluminum material, the two electromagnets 16 are started and affected by the magnetic force generated by them. The two electromagnets 16 move away from each other, and the electromagnet 16 drives the adjacent extrusion frames 15 to move synchronously, thereby causing the extrusion frame 15 to drive through the connecting shell 9 to move.

[0033] Further, such as Figure 4-Figure 6 and Figure 9 As shown, the connecting frame 5 is slidingly connected to a limiting frame 20, which is located between the adjacent connecting frame 5 and the adjacent positioning plate 6. The limiting frame 20 is used to limit the position of the connecting shell 9 in the adjacent second slide groove 18. A second spring 21 is fixed between the limiting frame 20 and the adjacent connecting frame 5. The limiting frame 20 is fixed with a fixing frame 22, and the fixing frame 22 is fixed with symmetrically distributed limiting plates 23. The limiting plates 23 are used to limit the position of the connecting shell 9 in the adjacent first slide groove 17. The positioning plate 6 is provided with an extrusion groove 24 on one side close to the adjacent limiting frame 20, and the extrusion groove 24 is used to guide the movement of the adjacent limiting frame 20.

[0034] Further, such as Figure 5 、 Figure 6 and Figure 9 As shown, the limiting plate 23 is composed of a straight plate and an arc plate. The arc plate of the limiting plate 23 is used to limit the position of the adjacent connecting shell 9, and the straight plate of the limiting plate 23 is used to guide the deflection of the adjacent connecting shell 9. The length of the straight plate on the limiting plate 23 is greater than the length of the adjacent first slide groove 17.

[0035] Further, such as Figure 4 and Figure 9As shown, the depth of the extrusion groove 24 increases as the distance between the extrusion groove 24 and the adjacent extrusion frame 15 increases.

[0036] The above solution provides a way to limit the position of the connecting shell 9; Figure 2 Taking the position of the parts on the middle left connecting frame 5 as an example, the limit frame 20 is located in the middle of the lower side of the adjacent connecting frame 5. The limit frame 20 is used to limit the position of the middle connecting shell 9, ensuring that the middle connecting shell 9 is initially located at the right position of the second slide groove 18, so that the connecting shell 9 is in a vertical state. The limit frame 20 is composed of a vertical plate, a straight rod and an arc plate, wherein the arc plate of the limit frame 20 is used to clamp the middle connecting shell 9 so that it cannot move, and the second spring 21 is used to push the limit frame 20 to move to the right and reset. The fixed frame 22 is located in the middle of the adjacent limit frame 20, and a fixed frame 22 has two limit plates 23 symmetrically distributed front and back. The arc plates of the two limit plates 23 are located on the opposite sides between them. Initially, the limit plate 23 The arc plate and straight plate together clamp the adjacent connecting shell 9 so that it cannot move. When the limit plate 23 is reset to the right, the straight plate on the limit plate 23 is used to push the adjacent connecting shell 9 to move in the opposite direction and reset. The length of the straight plate on the limit plate 23 is used to ensure that it can contact the adjacent connecting shell 9 when it moves to the right. An extrusion groove 24 is provided in the middle of the upper side of the positioning plate 6. The depth of the extrusion groove 24 gradually decreases from left to right. In the process of the connecting frame 5 driving the limit frame 20 to move downward, when the vertical plate on the limit frame 20 contacts the extrusion groove 24, the extrusion groove 24 squeezes the vertical plate on the limit frame 20 to move it to the left, and then the limit frame 20 drives the two limit plates 23 to move to the left through the parts thereon to release the limit on the positions of the three adjacent connecting shells 9.

[0037] When the existing shearing device is shearing aluminum, the downward force applied to the shearing point of the aluminum causes the shearing point of the aluminum to move downward, thereby causing the adjacent areas of the shearing point of the aluminum to gather towards this position, resulting in the edge of the aluminum being warped and deformed, affecting the normal shearing of the aluminum.

[0038] Further, such as Figure 5 、 Figure 8 and Figure 9 As shown, two symmetrically distributed transmission blocks 25 are fixed to one side of the connecting frame 5 close to the adjacent positioning plate 6, and the positioning plate 6 is slidably connected to two symmetrically distributed extrusion blocks 26. The transmission blocks 25 and the adjacent extrusion blocks 26 are provided with inclined surfaces on the opposite sides. The inclined surfaces of the transmission blocks 25 are used to push the adjacent extrusion blocks 26 to move, and a third spring 27 is fixed between the extrusion blocks 26 and the adjacent positioning plate 6.

[0039] Further, such as Figure 5 、 Figure 8 and Figure 9As shown, the lower side of the extrusion block 26 is lower than the lower side of the adjacent positioning plate 6, and the protruding height of all the extrusion blocks 26 on the same positioning plate 6 increases as the distance between the two decreases.

[0040] The above solution provides a way to further limit the deformation range of aluminum; Figure 2 Taking the position of the parts on the left connecting frame 5 as an example, the right part of the lower side of the connecting frame 5 is fixed with two transmission blocks 25 symmetrically distributed front and back, and the inclined surfaces of the two transmission blocks 25 are used to push the corresponding two extrusion blocks 26 away from each other, and the right part of the positioning plate 6 is slidably connected with two extrusion blocks 26 symmetrically distributed front and back. The extrusion blocks 26 are made of elastic material. The height of the lower side of the two extrusion blocks 26 on the same positioning plate 6 gradually increases from the side where the two extrusion blocks 26 are close to each other to the side where the two are away from each other. The lower side of the extrusion block 26 is used to extrude the corner of the aluminum material, thereby applying an outward thrust to the corner of the upper side of the aluminum material, limiting the deformation of the edge position of the aluminum material, thereby further reducing the probability of deformation of the upper side of the aluminum material, and the third spring 27 is used to push The extrusion block 26 moves in the opposite direction and resets; in the process of the above-mentioned positioning plate 6 moving downward, when the extrusion block 26 contacts the aluminum material, the positioning plate 6 continues to move downward, causing the extrusion block 26 to deform and extrude the corner of the upper side of the aluminum material. Until the positioning plate 6 contacts the aluminum material, the positioning plate 6 and the parts thereon stop moving. As the connecting frame 5 drives the transmission block 25 to continue to move downward, when the transmission block 25 contacts the extrusion block 26, the transmission block 25 squeezes the adjacent extrusion block 26 through the inclined surface thereon, so that the two extrusion blocks 26 on the same positioning plate 6 are pushed to move in reverse, so that the extrusion block 26 applies an outward extrusion force to the corner of the aluminum material, reducing the probability of the aluminum material shrinking inward during the shearing process, thereby further increasing the stability of the upper side of the aluminum material.

[0041] While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments.
