Description

Technical Field

[0001] The invention relates to the technical field of plate shearing machines, and particularly provides an automatic plate shearing machine for architectural decorative aluminum profiles. Background Art

[0002] Aluminum profile shearing machine is a metal processing equipment specially used for shearing various types of aluminum profiles. Its core function is to accurately shear aluminum profiles according to the set size and shape through the relative movement of the upper and lower blades. It is widely used in aerospace, automobile manufacturing, electronic equipment, architectural decoration and other industries. Aluminum profiles are usually divided into aluminum plates and aluminum sheets according to their thickness. When using shearing machines for processing, aluminum sheets are prone to wavy edges due to their poor rigidity, which affects the shearing effect.

[0003] During the cutting process, the elastic point pressure structure on the shearing machine will perform point pressure positioning on the aluminum material to be cut to prevent the aluminum material from shaking during the cutting process, thereby avoiding the generation of wave patterns as much as possible. However, due to the hysteresis of the elastic deformation of the spring or rubber pad, when the shear force increases instantly, the elastic element will reduce the actual pressing force due to compression deformation, causing the plate to lose sufficient constraint at the critical moment and produce instantaneous deformation, which makes it difficult to effectively avoid the generation of wave patterns. When cutting aluminum, especially for thin and wide aluminum sheets, the shear force at the cutting point of the aluminum will also act instantly on the surface of the aluminum. Since the position of the cutting point is constantly changing, the point pressure positioning cannot correspond to the cutting point in real time. Therefore, the cutting point will form wave patterns due to the release of internal stress. At the same time, aluminum chips are easily adhered to the surface of the blade. When cutting, aluminum chips act on the aluminum sheet, which will still cause wave patterns, thereby affecting the cutting effect of the shearing machine. Summary of the Invention

DETAILED DESCRIPTION

[0031] 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.

[0032] In order to enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] Figure 1 Disclosed is an automatic shearing machine for building decorative aluminum profiles. The aluminum profiles enter the shearing machine workbench 2 and the shearing position can be achieved through a variety of methods such as conveyor belts, unwinding aluminum rollers and manual transmission. The sheared aluminum profiles are output at equal distances through the conveyor tool behind the shearing machine.

[0034] like Figure 1 、 Figure 3 、 Figure 6 and Figure 7As shown, a processing groove 1 is opened on the surface of the workbench 2, and the processing groove 1 runs through from top to bottom. A gantry 4 is fixedly installed on the upper surface of the workbench 2, and the gantry 4 is located directly above the processing groove 1. A tool holder 10 is slidably installed inside the gantry 4. The tool holder 10 contains a blade for cutting aluminum. An electric push rod 11 is fixedly installed on the surface of the gantry 4, and the output shaft of the electric push rod 11 is fixedly installed on the surface of the tool holder 10. The electric push rod 11 is used to drive the tool holder 10 to move longitudinally to cut the aluminum. In order to prevent the blade on the tool holder 10 from instantly cutting and falling on the aluminum, causing the internal stress of the aluminum to be suddenly released to produce a wavy edge, the tool holder 10 is assembled in an inclined manner. When the tool holder 10 gradually descends for cutting, the edge of the blade is progressively cut to achieve single-point cutting of the aluminum, so that the internal stress of the aluminum is gradually released, reducing the generation of wavy patterns.

[0035] like Figure 1-Figure 3 As shown, elastic point pressure components 5 are installed on both sides of the gantry 4, and the two groups of point pressure components 5 are fixedly connected by a U-shaped connecting frame 12. A connecting rod 13 is fixedly installed between the connecting frame 12 and the tool holder 10. When the tool holder 10 moves longitudinally, it can drive the connecting frame 12 to move longitudinally. A guide component 14 is set between the point pressure component 5 and the gantry 4 to prevent the point pressure component 5 from moving and causing deviation. It should be noted that the lower end position of the point pressure component 5 is lower than the lower end position of the tool holder 10. When the tool holder 10 moves downward, the point pressure component 5 will first contact the aluminum material. During the continuous downward movement, the inside of the point pressure component 5 will gradually be elastically compressed, and the aluminum material is positioned by using the elastic compression rebound force of the point pressure component 5. When the tool holder 10 gradually moves upward, the point pressure component 5 is also gradually released and slowly moves away from the aluminum material.

[0036] like Figure 1 、 Figure 6-Figure 9 As shown, in order to provide real-time positioning for the aluminum material in the cutting state and reduce the impact of internal stress release on the cutting edge, a support component 6 is installed inside the processing groove 1 to provide real-time support force for the aluminum material in cutting and prevent the tool holder 10 from exerting excessive shearing force on the aluminum material to cause wavy edges.

[0037] The support assembly 6 includes an L-shaped support frame 601. The support frames 601 are arranged in multiples and divided into two groups. They are symmetrically installed inside the processing tank 1. The support frames 601 of each group are closely arranged and installed equidistantly from front to back. It should be noted that the upper surface of the support frame 601 is completely flush with the upper surface of the workbench 2. When the aluminum material is placed on the workbench 2, the aluminum material can just overlap the surface of the support frame 601. The support frame 601 provides support for the aluminum material. A plurality of support frames 601 that are aligned with the support frame 601 are fixedly assembled inside the processing tank 1. The corresponding U-shaped frame 602 has a circular shaft installed inside the U-shaped frame 602, which is movably inserted into the surface of the support frame 601. The support frame 601 can rotate around the circular shaft, and a torsion spring 603 is movably sleeved on the surface of the circular shaft. One end of the torsion spring 603 is fixed to the surface of the support frame 601, and the other end of the torsion spring 603 is fixed to the surface of the U-shaped frame 602. When the torsion spring 603 is in a compressed state, the distance between the two adjacent support frames 601 on the left and right is the shortest, providing support force for the aluminum material closest to the cutting position.

[0038] In order to prevent the support frame 601 from rotating due to the rebound force of the torsion spring 603, a driving assembly 7 is installed inside the workbench 2. The driving assembly 7 can make the support frame 601 rotate gradually in sequence. It should be noted that the distance between the rotation axis and the side of the support frame 601 before rotation is greater than the distance between the axis and the side after rotation. Therefore, the distance between the left and right support frames 601 becomes larger after rotation to avoid the tool holder 10. It should be noted that the distance from the top of the support frame 601 to the horizontal plane of the rotation center before rotation is the same as the distance from the top of the support frame 601 to the horizontal plane of the rotation center after rotation. At this time, it can be ensured that the top height of the support frame 601 before and after rotation is always flush with the workbench 2. At this time, the tool holder 10 can smoothly fall between the two adjacent support frames 601, and the support frame 601 after rotation can still provide a certain supporting force for the cut aluminum material.

[0039] The driving assembly 7 includes a tilted support plate 701, which is fixedly mounted on the lower surface of the support frame 601, and an extrusion plate 702 is movably mounted inside the workbench 2. A rotating shaft is rotatably mounted on one end of the extrusion plate 702, and the rotating shaft is mounted inside the workbench 2. The extrusion plate 702 can rotate around the rotating shaft, and an arc-shaped rack 703 is fixedly mounted on the other end of the extrusion plate 702. The rack 703 is located inside the workbench 2. When the extrusion plate 702 rotates and gradually moves away from the support plate 701, the rebound force of the torsion spring 603 drives the support frame 601 to rotate and gradually moves away from the descending tool holder 10. The method of driving the support frame 601 to rotate one by one can not only prevent the tool holder from The rack 10 does not cause the problem of knife collision, and at the same time it can provide more stable support force for the aluminum material in the uncut position, further reducing the generation of wave ripples. A gear 704 is rotatably installed inside the workbench 2, and the gear 704 can engage with the rack 703. The gear 704 can be driven by an external drive source (not shown in the figure). When the knife rack 10 finishes cutting and moves upward, the extrusion plate 702 rotates in the opposite direction. Since the extrusion plate 702 rotates around the rotating shaft, the surface closest to the rotating shaft will first contact the extrusion support plate 701 when rotating, until the extrusion plate 702 rotates to a horizontal state, all the support plates 701 are squeezed at the same time, and at this time the support rack 601 returns to its initial state.

[0040] like Figure 2-Figure 6 As shown, in order to facilitate simultaneous use with the support frame 601, a pressing component 9 is installed on the surface of the gantry 4. When the cutting position changes, the pressing position of the pressing component 9 will also change accordingly. By controlling the point pressing method, the internal stress change of the cutting point can be effectively buffered to avoid the wave pattern phenomenon caused by excessive pressing force range or inaccurate pressing force position. The pressing component 9 is also set to be liftable.

[0041] The pressing assembly 9 includes two mounting frames 901 located on both sides of the tool holder 10. The two mounting frames 901 are installed and fixed through a U-shaped connecting frame 903. An electric push rod 904 is fixedly installed on the surface of the gantry 4. The output shaft of the electric push rod 904 is fixed on the surface of the connecting frame 903, thereby realizing the lifting and lowering of the pressing assembly 9. A pressing roller 902 is movably installed on the surface of the mounting frame 901. The lower end of the pressing roller 902 is tightly attached to the surface of the aluminum material. The pressing roller 902 can roll back and forth along the mounting frame 901. As the cutting position changes, it rolls to the corresponding position and cooperates with the support assembly 6 to realize real-time clamping and positioning.

[0042] The mounting frame 1 901 is in the shape of an elongated strip and hollow inside, with both sides connected to the outside. A plurality of tooth grooves 905 are provided at the bottom inside the mounting frame 1 901. Gear 2 906 is assembled inside the mounting frame 1 901. Gear 2 906 is meshed with the tooth groove 905. The pressing roller 902 is coaxially fixed with gear 2 906. When gear 2 906 rolls inside the tooth groove 905, the pressing roller 902 will also roll accordingly. A motor 907 is coaxially installed on the surface of the other side of gear 2 906. When the output shaft of motor 907 rotates, it will drive gear 2 906 to rotate and roll, thereby realizing the rotation and rolling of the pressing roller 902. It should be noted that at this time, gear 2 906 is in a meshing state with the tooth groove 905, and the lower end of the pressing roller 902 is lower than the lower end of the mounting frame 1 901.

[0043] In order to further reduce the problem of wavy lines on the cutting edge, a spring 908 and an elastic plate 909 are installed inside the mounting frame 1 901. One end of the spring 1 908 is fixed to the surface of the elastic plate 909, and the other end of the spring 1 908 is fixed to the inside of the mounting frame 1 901. A gap is set between the gear 2 906 and the top of the inner wall of the mounting frame 1 901. When the pressing roller 902 moves from one end away from the spring 1 908 to the other end, the aluminum cutting is completed. At this time, the gear 2 906 moves to squeeze the elastic plate 909, and the elastic plate 909 squeezes the spring 1 908, so that the spring 1 908 is in a compressed state. Due to the engagement of the tooth groove 905 and the gear 2 906, the pressing roller 902 cannot return to the initial position. At this time, the mounting frame 1 901 moves upward to drive the pressing roller 902 away from the aluminum material and pull the aluminum material in the direction of the two pressing rollers 902 respectively. The aluminum material can be pulled by the conveyor belt or the conveyor roller, which mainly depends on the production process. The state of the aluminum material itself during the production process is that the aluminum sheet is usually conveyed by a conveyor belt, and the aluminum coil is pulled and conveyed by a conveyor roller, so that the cut edge of the aluminum material is located directly below the pressing roller 902. At this time, the mounting frame 1 901 moves down so that the pressing roller 902 contacts the cut edge of the aluminum material. At this time, the lower end of the pressing roller 902 is lower than the lower end of the mounting frame 1 901, and then the mounting frame 1 continues to move down again. Since the pressing roller 902 cannot move further down, the mounting frame 1 901 and the pressing roller 902 produce relative movement, and the pressing roller 902 drives the tooth groove 905 to separate from the gear 2 906. At this time, the rebound force of the spring 1 908 quickly squeezes the gear 2 906 to reset and move, and the pressing roller 902 will also move accordingly, quickly flattening the cut edge of the aluminum material, and the pressing roller 902 quickly returns to its initial state, which is convenient for the next positioning and pressing, thereby ensuring the continuity of the operation while pressing the cut edge of the aluminum material.

[0044] In order to prevent the gear 2 906 from being worn out due to the kinetic energy converted from the elastic potential energy when the gear 2 906 is reset, a spring 1 908 (the length and elastic coefficient of the spring 1 908 at both ends can be selected according to actual needs) and an elastic plate 909 are also installed at the other end of the mounting frame 901, which are used for buffering during the return movement of the gear 2 906, and a buffer plate 15 that can rotate around the gear shaft is installed on the back of the gear 2 906. The front and rear sides of the buffer plate 15 are both located outside the range of the gear 2 906 to ensure that when the buffer plate 15 moves with the gear 2 906, the buffer plate 15 is the first to contact the elastic plate 909. The buffer plate 15 is connected to the external motor 907 through a fixed rod to prevent the buffer plate 15 from rotating with the gear 2 906. The top of the inner wall of the mounting frame 1 901 is equipped with a limit block 16 with an inclined surface on one side. The top of the inner wall of the mounting frame 1 901 is provided with a groove. The spring 3 17 is fixedly installed in the groove. The limit block 16 is fixedly installed at the lower end of the spring 3 17. During the rebound of the gear 2 906, the buffer plate 15 will first contact the limit block 16 for a buffer. At this time, the spring 3 17 is compressed, the limit block 16 is located in the groove, and the buffer plate 15 will smoothly rest on the surface of the elastic plate 909. At this time, the spring 3 17 drives the limit block 16 to reset downward. After contacting the elastic plate 909, the buffer plate 15 may rebound again. The rebounded buffer plate 15 is limited by the limit block 16, thereby limiting the reset gear 2 906 and avoiding impact on the gear 2 906. In order to reduce the resistance of the buffer plate 15 when it moves, a ball bearing can be rotatably installed on its top.

[0045] In order to prevent the motor 907 from rotating, an anti-rotation component 3 is installed on the surface of the motor 907 to prevent the motor 907 from rotating. The anti-rotation component 3 includes limit plates 301 fixedly installed on both sides of the mounting frame 901, and a guide rod 302 vertically movable through the surface of the base of the motor 907. A reset spring is connected between the guide rod 302 and the base of the motor 907. The reset spring is not shown in the figure. When the mounting frame 901 is reset upward to its bottom end and separated from the aluminum material, the elastic force of the reset spring drives the gear 2 906 to re-engage with the tooth groove 905, and the motor 907 can move axially along the guide rod 302. The top and bottom of the guide rod 302 slide against the surfaces of the two limit plates 301 respectively, which can not only effectively prevent the motor 907 from rotating, but also the motor 907 will not affect the movement of the pressing roller 902.

[0046] like Figure 1 ,like Figure 7 、 Figure 10 and Figure 11As shown, since the tool holder 10 is prone to sticking aluminum chips during the process of cutting aluminum materials, the aluminum chips stick to the blade to form a protrusion, which will change the actual rake angle of the tool, resulting in an increase in the amplitude of shear force fluctuations. The instantaneous impact force causes local bending of the plate, thereby forming wave patterns. Therefore, a cleaning component 8 is assembled in the downward movement path of the tool holder 10 to clean the aluminum chips on the tool.

[0047] The cleaning assembly 8 includes two round roller-shaped cleaning strips 801, the surfaces of the two cleaning strips 801 are in contact with each other, and the two cleaning strips 801 are respectively located on both sides of the tool holder 10. Two mounting frames 805 are symmetrically installed inside the processing groove 1. The cleaning strips 801 are rotatably installed inside the mounting frame 805, and the two cleaning strips 801 are driven to rotate in opposite directions by external means. The support rod fixedly installed on the surface of the mounting frame 805 is movably connected to the workbench 2, and the spring 802 is movably sleeved on the surface of the support rod. When the tool holder 10 moves down to the extrusion mounting frame 805 after cutting, the spring 802 will be compressed. At this time, the pressure of the spring 802 will cause the cleaning strip 801 to press against the tool of the tool holder 10, and then the cleaning strip 801 rotates to clean the tool on the tool holder 10.

[0048] A cleaning plate 803 is fixedly installed inside the second mounting frame 805. The side of the cleaning plate 803 is pressed against the surface of the cleaning strip 801. When the cleaning strip 801 rotates, the aluminum chips are scraped off and fall on the surface of the cleaning plate 803. The side of the cleaning plate 803 away from the cleaning strip 801 is lower than the side close to the cleaning strip 801. The aluminum chips will fall due to gravity. An inclined guide plate 804 is assembled inside the second mounting frame 805. The aluminum chips fall on the surface of the guide plate 804 and accumulate at a lower position due to gravity so that they can be cleaned uniformly at the end.

[0049] The present invention provides an automatic shearing machine for architectural decorative aluminum profiles. The aluminum profile is placed at a position where it needs to be sheared, and the electric push rod 2 904 moves downward, so that the surface of the pressing roller 902 contacts the surface of the aluminum profile. Then the electric push rod 11 drives the knife holder 10 to move longitudinally to cut the aluminum profile. During this process, the motor 907 is started, driving the gear 2 906 to rotate and roll, thereby realizing the rotation and rolling of the pressing roller 902. At the same time, the external driving source drives the gear 1 704 to rotate. Due to the meshing of the rack 703 and the gear 1 704, the end of the extrusion plate 702 can be pulled to move. The extrusion plate 702 rotates around the rotating shaft and gradually moves away from the support plate 701. The support frame 601 rotates, which makes it easier for the tool on the knife holder 10 to cut the aluminum profile. The support frame 601 and the pressing roller 902 act on the cutting point position at the same time. To offset the release of internal stress, the tool holder 10 continues to move downward, and the cleaning strip 801 cleans the tool. During this process, the mounting frame 1 901 moves upward to drive the pressing roller 902 away from the aluminum material, and pulls the aluminum material in the direction of the two pressing rollers 902, so that the cutting edge of the aluminum material is located directly below the pressing roller 902. At this time, the mounting frame 1 901 moves downward so that the pressing roller 902 contacts the cutting edge of the aluminum material. The mounting frame 1 901 continues to move downward again, so that the tooth groove 905 is separated from the gear 2 906. The rebound force of the spring 1 908 quickly squeezes the gear 2 906 to move. At this time, the pressing roller 902 will also move accordingly to flatten the cutting edge of the aluminum material, and the pressing roller 902 returns to its initial state. Finally, the aluminum material is cut. The tool holder 10, the pressing roller 902 and the point pressure component 5 all return to their initial positions for easy use in the next cutting.
