Description

Technical Field

[0001] The invention relates to the technical field of aluminum-plastic plate manufacturing, in particular to an aluminum-plastic plate manufacturing stamping forming machine. Background Art

[0002] Aluminum-plastic panels are building decoration materials made of multiple layers of materials. They are widely used in construction, advertising and other fields. Most of them are 0.2-0.5mm thick aluminum alloy plates. Usually 3003 series or 5005 series aluminum alloys are used. They have good corrosion resistance, weather resistance and strength. The surface is treated by anodizing, electrostatic spraying, etc., which can form decorative effects of various colors and glossiness.

[0003] For aluminum-plastic panels used for decoration, the surface usually needs to be stamped and shaped, and punched when necessary. For example, the patent document with announcement number CN111112421B mentions a multifunctional stamping forming machine that can combine stamping deformation and punching. The aluminum-plastic panel is fixedly clamped by a suction cup and a clamping plate during the stamping process to avoid the problem of reduced production efficiency caused by frequent transfer of the aluminum-plastic panel for step-by-step operation; however, for aluminum-plastic panels with multiple stampings on the panel surface, stamping and forming cannot achieve mobile positioning. At the same time, the aluminum-plastic panel has a high adaptability to the mold, and it is difficult to suck the deformed panel surface and clamp the clamping plate to demould;

[0004] For this purpose, we propose a stamping forming machine for manufacturing aluminum-plastic panels. Summary of the invention

[0005] The object of the present invention is to provide a stamping machine for manufacturing aluminum-plastic panels to solve the problems raised in the above-mentioned background technology;

[0006] To achieve the above object, the present invention provides the following technical solution: an aluminum-plastic plate manufacturing stamping forming machine, comprising a base and a limit platform, the top of the base is fixed to the limit platform by bolts, and the inner walls on both sides of the limit platform are slidably connected with a positioning and lifting mechanism;

[0007] The positioning and lifting mechanism comprises a sliding shell, a rotating arm 1 and a combined arm, the inner walls on both sides of the limit platform are slidably connected with the sliding shell, the top of the sliding shell is movably connected with the rotating arm 1 through a bearing, and the inner walls on both sides of the sliding shell are evenly and symmetrically connected with the combined arm;

[0008] The inner walls on both sides of the sliding shell are slidably connected with a placing slide, the bottom of the placing slide is fixed with an upper mold by bolts, one side of the limit platform is fixed with a driving assembly by bolts, and the output end of the driving assembly passes through the limit platform and is fixedly connected with a cam, a pressure rod is movably connected to the cam, one end of the pressure rod passes through the top groove of the sliding shell and is movably connected to the placing slide, a positioning frame is symmetrically installed with bolts on the top of the base, a lower mold is fixed with bolts on the top of the positioning frame, and the lower mold is correspondingly arranged to the upper mold.

[0009] Furthermore, a slide assembly 2 is slidably connected to the top track of the base, a clamp is installed on the slide assembly 2, a translation assembly 2 is fixed to the top of the base by bolts, and the cylinder end of the translation assembly 2 is connected to the slide assembly 2.

[0010] Furthermore, a slide assembly 1 is slidably connected to the top track of the limit platform, a claw box is fixed to the bottom plate of the slide assembly 1 by bolts, a claw head is installed at the bottom of the claw box, and a translation assembly 1 is fixed to the top of the limit platform by bolts, and the cylinder end of the translation assembly 1 is fixed to the slide assembly 1.

[0011] Furthermore, a second rotating arm is movably connected to the limit platform and is located on the cam side. One end of the second rotating arm is movably connected to the first rotating arm, and the other end of the second rotating arm is movably connected to the side connecting rod of the limit platform.

[0012] Furthermore, slide plates are symmetrically slidably connected in grooves on both sides of the inner wall of the sliding shell, a slider is slidably clamped on the slide plate, and one end of the combined arm is slidably connected to the slider.

[0013] Furthermore, a threaded rotating rod is evenly and movably connected to the top of the sliding shell, one end of the threaded rotating rod passes through the sliding shell and is movably connected to the side of the sliding plate, and a spring is symmetrically sleeved and installed on the connection side of the sliding block and the sliding plate.

[0014] The use method of the aluminum-plastic panel manufacturing stamping forming machine is as follows:

[0015] Adaptive positioning stamping: place one end of the aluminum-plastic panel stored on the positioning frame side on the slide assembly 2, control the fixture to clamp the aluminum-plastic panel on one side, and cooperate with the upper translation assembly 2 to move the panel;

[0016] Control the angle of the combined arm according to the width of the aluminum-plastic plate, and rotate the threaded rod on the top of the sliding shell to make the end of the single-side arm of the combined arms on both sides contact the aluminum-plastic plate and extend 1-2mm;

[0017] The second translation component is controlled to slide the aluminum-plastic plate to a certain size, and the driving component controls the rotation of the cam on the limit table to realize the movement of the pressure rod while controlling the swing arm second to swing. Before the upper mold at the bottom of the slide table contacts the aluminum-plastic plate, the combined arm on the slide shell first contacts the two sides of the extruded aluminum-plastic plate on one side to complete the centering calibration. At the same time, as the combined arm continues to extrude, the upper mold contacts and completes the stamping of the aluminum-plastic plate. Subsequently, the combined arm increases the inner angle due to continuous extrusion, and the central axis side of the combined arm moves to the bottom of the aluminum-plastic plate that is in contact with the stamping, and as the upper mold rises, the aluminum-plastic plate that has been stamped is driven to move upward in advance, completing the collision between the aluminum-plastic plate and the upper mold, thereby realizing automatic demoulding of the aluminum-plastic plate that is in contact with the stamping.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. In the present invention, the stamping combined accessories are installed, the conventional cam is used to rotate to drive the placement slide, and the second rotating arm is installed to carry out the accompanying movement of the side sliding shell of the placement slide. The sliding shell that moves first is installed by the combination arm to center and press the aluminum-plastic plate to be stamped, and the aluminum-plastic plate is lifted and demoulded after the stamping is completed. The placement slide and the sliding shell move closely, which improves the processing efficiency of continuous stamping of aluminum-plastic plates and is safe to operate;

[0020] 2. In the present invention, the inner angle of the combined arm is actively adjusted to provide conditions for adapting to the stamping of aluminum-plastic panels of different sizes, avoiding the need for corresponding fixture signals and position adjustments due to the replacement of the aluminum-plastic panels. The overall adaptability of the stamping machine is relatively high. At the same time, the installation of the translation component 1 and the claw box on the top of the limit table can also automatically grab and transport the stamping panels detached from the translation component 2, further improving the overall stamping efficiency of the aluminum-plastic panels.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0030] See also Figure 1-7 , the present invention provides a technical solution:

[0031] Example 1: For aluminum-plastic panels for architectural decoration, when pattern stamping or continuous punching is performed on the surface, if the panel surface cannot be adapted to the stamping machine, a step-by-step stamping process is used. The panel is pre-stamped first to give it a preliminary shape, and then subsequent stamping processes are performed as needed to gradually achieve the final forming effect. Considering the movement and demoulding operations required during the continuous stamping process, Figure 1 As shown, the automatic traction component is used to move the plate, and the upper stamping component is used for extrusion to complete continuous forming. At the same time, the stamping plate can be automatically demoulded and subsequently unloaded;

[0032] The positioning frame 7 is fixed on the top of the base 1. Taking the punching of the aluminum-plastic plate as an example, the aluminum-plastic plate is placed on the positioning frame 7, and the clamp 9 on the slide assembly 8 presses the plate surface, and then the aluminum-plastic plate is pulled by adjusting the translation assembly 10 with the movement parameters adjusted;

[0033] The slide 13 and the positioning and lifting mechanism 14 are installed in combination on the limiting platform 2 located on the top of the base 1. Figure 6 As shown, the upper mold 15 is installed at the bottom of the placement slide 13, and the placement slide 13 is located on the inner wall of the slide shell 141, and is located on the limit platform 2 for driving assembly installation, and the cam 11 fixedly connected to the end of the motor rotates, and one end of the pressure rod 12 sleeved on the side of the cam 11 is movably connected to the placement slide 13. With the rotation of the cam 11, the pressure rod 12 swinging up and down drives the placement slide 13 to move inside the slide shell 141, so as to realize the pressing operation of the upper mold 15 at the bottom and the aluminum-plastic plate placed on the surface of the lower mold 16;

[0034] Since the stamping of the aluminum-plastic plate is a continuous operation, the deformed plate needs to be demolded and moved. If the plate is directly deformed or punched, the plate surface will be worn and scratched due to the incomplete separation of the plate from the mold during traction and pulling. Therefore, the positioning and lifting mechanism 14 is installed on the original placement slide 13;

[0035] like Figure 7As shown, the whole slide 13 is half-enclosed by a cover shell, and the inner walls of both sides of the slide shell 141 are symmetrically installed with combined arms 143, and the combined arms 143 are movably connected to the slider 20 on the inner wall of the slide shell 141 on one side, and the entire slider 20 is installed on the slide plate 18, and the slider 20 can slide as a whole, and a spring 21 is also sleeved and installed between the slider 20 and the slide plate 18, and the triangular combined arms 143 begin to contact the two sides of the aluminum-plastic plate during the movement of the slide shell 141, and the inclined surface design squeezes the aluminum-plastic plate inward at the same time, so that the aluminum-plastic plate is automatically centered and pressed on the lower mold 16;

[0036] For the overall drive of the positioning and lifting mechanism 14, it is necessary to complete the centering and pressing of the aluminum-plastic plate before the upper mold 15 at the bottom of the slide 13 contacts the aluminum-plastic plate to avoid the movement of the aluminum-plastic plate during the stamping process, and to complete the reset of the combined arm 143 as soon as possible after the stamping is completed;

[0037] For this reason, Figure 5 As shown, a rotatable arm 2 17 is movably mounted on the original cam 11, one end of the rotatable arm 2 17 is connected to a rotatable arm 1 142 movable on the top of the sliding shell 141, and the other end is movably connected to the connecting rod on the limit platform 2. When the cam 11 rotates, the pressure rod 12 pushes the placement slide 13 to move, and due to the limit of the connecting rod, the rotatable arm 2 17 swings clockwise, and the downward pressing amplitude of the end of the rotatable arm 2 17 is greater than the pressure rod 12 on the cam 11, so that the downward pressing movement speed and downward moving distance of the sliding shell 141 are greater than the placement slide 13;

[0038] At this time, one end of the combined arm 143 starts to contact the two sides of the aluminum-plastic plate during the movement process, completing the pressing of the two sides of the aluminum-plastic plate, and continues to move downward when the upper mold 15 at the bottom of the slide 13 contacts the plate surface. At this time, the combined arm 143 needs to be separated from the contact with the plate surface, and it starts to move itself. The combined arm 143 starts to press the spring 21 connected to the slider 20 side upward on one side, so that the inner angle of the combined arm 143 increases and breaks away from the contact with the plate, and moves the turning center of the combined arm 143 from the top of the plate to the bottom of the plate.

[0039] With the completion of the stamping of the aluminum-plastic plate, the combined arm 143 that moves upward in advance pushes the aluminum-plastic plate on the lower mold 16 to move again. The moving speed of the sliding shell 141 is greater than the placement slide 13, causing the stamped aluminum-plastic plate pushed upward to hit the upper mold 15. The rotation center of the combined arm 143 squeezes the aluminum-plastic plate and again separates it from the plate surface through the squeezing spring 21, that is, the automatic demoulding of the aluminum-plastic plate after stamping is realized. Compared with the manual or mechanical arm entry-type aluminum-plastic plate movement, the rapid demoulding after stamping improves the overall subsequent stamping efficiency and makes the stamping operation safer.

[0040] By moving the combined arm 143 on the sliding shell 141 up and down first, and cooperating with the normal movement of the placement slide 13, efficient stamping is achieved while completing the subsequent automatic demoulding of the aluminum-plastic plate. For the aluminum-plastic plate after demoulding, the cylinder on the translation component 2 10 pulls the plate to move, which will not cause contact damage to the aluminum-plastic plate after shaping. At the same time, the subsequent placement slide 13 is for uninterrupted stamping, thereby achieving efficient and continuous stamping operations of the entire aluminum-plastic plate.

[0041] Embodiment 2: Considering the different widths of different aluminum-plastic panels, the combination arms 143 placed at a uniform angle are used for centering and pressing during stamping, which may easily lead to failure to normally squeeze and separate when the aluminum-plastic panel with a larger width is squeezed, causing deformation of the edge of the aluminum-plastic panel, and in severe cases, causing the combination arm 143 to break. Therefore, when the aluminum-plastic panel is stamped, the inner extension distance of the combination arm 143 is adjusted according to the width of the aluminum-plastic panel, that is, the inner angle of the combination arm 143 is adjusted;

[0042] like Figure 7 As shown, one end of the combined arm 143 is fixed to both sides of the slider 20 on the slide plate 18, and the slider 20 can slide slightly on the slide plate 18 and is constrained by the spring 21. A threaded rod 19 is movably connected to the top of the sliding shell 141, and the end of the threaded rod 19 is movably connected to the slider 20. With the manual rotation of the threaded rod 19, the entire slide plate 18 is adjusted to slide inside the sliding shell 141. When moving downward, the angle of the combined arm 143 decreases and the extension distance increases. When moving upward, the opposite is true. For this reason, the angle of the combined arm 143 is adjusted according to the width of the aluminum-plastic plate. Usually, the extension distance of the combined arm 143 is kept greater than the edge of the aluminum-plastic plate by 1-2mm, so that the combined arm 143 can be effectively lifted after the plate is pressed when the sliding shell 141 moves.

[0043] At the same time, the entire aluminum-plastic panel manufacturing stamping forming machine is also equipped with an automatic unloading mechanism, which is slidably connected to a slide assembly 3 on the top track of the limit platform 2, and a claw box 5 is fixedly connected to the bottom of the slide assembly 3. A claw head 6 is installed at the bottom of the claw box 5. The slide assembly 3 is pushed to move on the top of the limit platform 2 through the translation assembly 4, and the stamped aluminum-plastic panel pulled away by the translation assembly 2 10 is grabbed. The claw head 6 completes the clamping of both sides of the aluminum-plastic panel, and the panel that has completed stamping is automatically detached, thereby improving the stamping efficiency of subsequent panels.

[0044] The working principle of the present invention is as follows: one end of the aluminum-plastic plate stored on the side of the positioning frame 7 is placed on the slide assembly 2 8, the clamp 9 is controlled to clamp the aluminum-plastic plate on one side, and the upper translation assembly 2 10 is coordinated to move the plate;

[0045] The angle of the combined arm 143 is controlled according to the width of the aluminum-plastic plate, and the threaded rotary rod 19 at the top of the sliding shell 141 is rotated so that the end of the single-side arm of the combined arm 143 on both sides contacts the aluminum-plastic plate and exceeds 1-2mm;

[0046] The translation component 2 10 is controlled to slide the aluminum-plastic plate to a certain size, and the driving component controls the cam 11 on the limit platform 2 to rotate, so that the pressure rod 12 can be moved and the rotating arm 2 17 can be controlled to swing. Before the upper mold 15 placed at the bottom of the slide 13 contacts the aluminum-plastic plate, the combined arm 143 on the sliding shell 141 contacts the two sides of the extruded aluminum-plastic plate on one side to complete the centering calibration. At the same time, as the combined arm 143 continues to extrude, the upper mold 15 contacts and completes the stamping of the aluminum-plastic plate. Subsequently, the combined arm 143 increases the inner angle due to the continuous extrusion, and the central axis side of the combined arm 143 moves to the bottom of the aluminum-plastic plate that is in contact with the stamping, and as the upper mold 15 rises, the aluminum-plastic plate that has been stamped is driven to move upward in advance, completing the collision between the aluminum-plastic plate and the upper mold 15, thereby realizing the automatic demoulding of the aluminum-plastic plate that is in contact with the stamping.
