Description

Technical Field

[0001] The invention relates to the technical field of metal curtain wall processing, in particular to a stamping forming device for metal curtain wall aluminum plates. Background Art

[0002] As a modern building exterior wall decoration technology, metal curtain walls are widely used in the design of commercial and public buildings. Metal curtain walls can be made of a variety of different metal materials, such as aluminum plates, stainless steel plates and copper plates. Among them, aluminum plates are an important material for making metal curtain walls due to their light weight, high strength, corrosion resistance and easy processing.

[0003] Currently, when processing metal curtain walls, existing stamping equipment is mainly used to stamp rectangular aluminum plates to form the aluminum plates into the required shape. The specific operation is as follows: manually select the corresponding lower mold and upper mold according to the required shape, and install the two on the workbench and punch transmission system respectively. Then, manually place the flat aluminum plate between the upper mold and the lower mold. The punch transmission system works to make the upper mold stamp the aluminum plate. After stamping is completed, the aluminum plate is manually removed.

[0004] In the field of metal curtain wall aluminum panels, strip-shaped U-shaped aluminum panels are usually used as device panels on the supporting structure of open curtain wall systems. They can also be used as decorative coverings and transition connection treatments. In the current stamping process, if it is necessary to stamp a strip-shaped U-shaped aluminum panel, two symmetrical and rotatable lower molds are required. When not closed, the angle between the two lower molds is an obtuse angle. During stamping, the two lower molds are rotated and closed. At this time, the two lower molds together form the required U shape. The rotation process of the two lower molds facilitates demolding and removing the stamped workpiece, which is more widely used than traditional fixed mold stamping.

[0005] In order to reduce the influence of the elastic reset characteristics of the strip aluminum plate on the stamping effect, during stamping, after the aluminum plate is initially U-shaped, the two lower molds continue to rotate and apply pressure to the aluminum plate again through the upper ends of the two lower molds. By increasing the stamping stroke, the elastic reset of the aluminum plate is offset to ensure that the aluminum plate finally takes the required U shape, that is, the pressure holding operation is performed in the above manner.

[0006] The above-mentioned stamping process has the following problems: it is difficult to accurately control the holding pressure strength by adding a pressure stroke to offset the elastic reset of the aluminum plate, and it is easy for the straight section of the formed aluminum plate to deviate from the set vertical direction. The U-shaped forming accuracy of the U-shaped aluminum plate affects its appearance quality, assembly and connection process and functional requirements. Therefore, stamping accuracy is crucial. However, the current stamping and holding pressure methods easily lead to the precision of the stamped U-shaped aluminum plate being difficult to meet the use requirements. If the holding pressure is maintained by setting a holding area on both sides of the straight section of the aluminum plate, it is necessary to add a holding pressure structure on both sides of the straight section of the aluminum plate, that is, on the lower mold and the upper mold. However, since the lower mold itself needs to deflect slightly during the stamping process, it is difficult to increase the holding pressure area. Summary of the Invention

[0034] To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0035] like Figure 1 and Figure 3As shown, a stamping forming equipment for metal curtain wall aluminum plates is arranged on the workbench of a punch press, comprising: a base 1, on which the base 1 is fixedly installed, and a working groove 2 with an isosceles trapezoidal cross-section in the left and right directions and a larger upper portion and a smaller lower portion is provided on the base 1, and two front-to-back symmetrical lower molds 3 are placed in the working groove 2. Taking the front lower mold 3 as an example for explanation, the front lower mold 3 is a rectangular section and a trapezoidal section with an arc-shaped rear end face from top to bottom, and the opposite back surfaces of the two lower molds 3 are fixedly provided with a movable rod 4 passing through the base 1, and a strip groove for deflection of the movable rod 4 is provided on the base 1, and a reset spring 40 is commonly provided between the tail end of the movable rod 4 and the base 1, wherein the reset spring 40 is fixedly connected to the movable rod 4 and contacts and fits with the base 1; an upper mold 5 connected to the punch press transmission system (not shown in the figure) is fixedly installed on the upper side of the workbench.

[0036] like Figure 1 and Figure 2 As shown, a stamping mechanism 6 is commonly provided between the upper mold 5 and the workbench, and the stamping mechanism 6 includes a rib 60. The ribs 60 are slidably installed on the front and rear sides of the upper mold 5. The lower end surface of the rib 60 is provided with an inner caressing plate 61 and an outer caressing plate 62 distributed front and back for sliding up and down, and the inner caressing plate 61 is close to the upper mold 5. After the stamping action is completed, the rib 60 is moved back and forth left and right, and the elastic reset of the aluminum plate itself is offset by smoothing the vertical section of the aluminum plate by the inner caressing plate 61 and the outer caressing plate 62; in order to facilitate the inner caressing plate 61 and the outer caressing plate 62 to move to the opposite side of the straight section of the aluminum plate, the left and right sides of the opposite surface of the inner caressing plate 61 and the corresponding outer caressing plate 62 are chamfered; the upper end surface of the rib 60 is fixed with a handle for easy manual pushing.

[0037] like Figure 1 、 Figure 2 and Figure 4 As shown, mounting plates 63 are provided on both the front and rear sides of the base 1 for sliding left and right, and a support portion 64 for supporting the rib 60 is provided between the mounting plate 63 and the rib 60. The support portion 64 includes a plug-in block 640 for plugging and connecting with the mounting plate 63.

[0038] like Figure 2 and Figure 5 As shown, a locking portion 65 is commonly provided between the plug-in block 640 and the inner and outer caressing plates 61 and 62 , and the front and rear positions of the inner and outer caressing plates 61 and 62 are locked by the locking portion 65 .

[0039] like Figure 4 As shown, the upper mold 5 is provided with a lifting plate 66 that slides up and down. The lifting plate 66 passes through the upper mold 5 from front to back. The lifting plate 66 is driven by a cylinder to move. The rib plate 60 is lifted by the lifting plate 66 to avoid the stamping process.

[0040] Before performing the stamping operation, the corresponding upper mold 5, lower mold 3 and stamping mechanism 6 are selected according to the thickness and shape of the required stamped aluminum plate, and then the rib plate 60 is installed on the upper mold 5. This is the initial state. The lifting plate 66 lifts the rib plate 60 so that the inner and outer caressing plates 61 and 62 avoid the bending process of the front and rear ends of the aluminum plate to perform the stamping operation.

[0041] During operation, the aluminum plate is first placed flat on the base 1 manually, and the front and rear positions of the aluminum plate are manually adjusted so that the length direction of the aluminum plate is consistent with the length direction of the lower mold 3. Secondly, at the beginning, the opposite back surfaces of the two lower molds 3 are in close contact with the front and rear side walls of the working groove 2 respectively, and the angle between the vertical sections of the two lower molds 3 is an obtuse angle. Then the transmission system of the punch press works to move the upper mold 5 downward and exert downward pressure on the aluminum plate. The aluminum plate is deformed and gradually enters between the two lower molds 3. Finally, the aluminum plate is located between the lower mold 3 and the upper mold 5. During the above process, the upper end parts of the two lower molds 3 begin to deflect and approach, and finally the rectangular sections of both are facing upward, see Figure 2 , the aluminum plate becomes the required U-shape, maintaining the closed state of the upper mold 5 and the lower mold 3.

[0042] The operation of the cylinder causes the lifting plate 66 to descend, and the rib plate 60 moves down synchronously. During the downward movement, the inner caressing plate 61 and the outer caressing plate 62 move down synchronously and are respectively located on the front and rear sides of the straight section of the aluminum plate. At this time, the rib plate 60 is located on the left side of the aluminum plate. Secondly, when the rib plate 60 moves down, the plug-in block 640 is plugged into the mounting plate 63, so that a rectangular frame is formed between the plug-in block 640, the inner caressing plate 61, the outer caressing plate 62, the rib plate 60 and the locking portion 65, thereby improving the stability of the moving smoothing.

[0043] The rib 60 is pushed manually by pushing the handle so that the inner caressing plate 61 and the corresponding outer caressing plate 62 are located on the front and rear sides of the straight section of the aluminum plate. Then, the locking part 65 is operated to lock the inner caressing plate 61 and the outer caressing plate 62 so that the two maintain the vertical orientation and horizontal spacing and keep a state of pressing the aluminum plate. Then, the rib 60 is pushed again manually and moves back and forth. During the movement, the inner caressing plate 61 and the corresponding outer caressing plate 62 cooperate with each other to shape the straight section of the aluminum plate by smoothing, ensuring that the aluminum plate is shaped into a U shape. After completing all operations, the upper mold 5 moves up and resets, and the rib 60 resets to the vertical section of the L-shaped groove 641, and the aluminum plate is taken out.

[0044] like Figure 3 and Figure 4 As shown, the front and rear end surfaces of the upper mold 5 are both provided with L-shaped grooves 641, the vertical section of the L-shaped groove 641 is located on the left side, a sliding block 642 is slidingly arranged in the L-shaped groove 641, and the rib plate 60 is installed on the sliding block 642. The installation method can be a detachable method such as a snap-on installation and a plug-in installation.

[0045] like Figure 2 、 Figure 4 and Figure 5 As shown, the rib plate 60 is provided with a connecting rod 643 that slides up and down, the plug-in block 640 is fixedly provided on the lower end surface of the connecting rod 643, and the upper end surface of the mounting plate 63 is provided with a plug-in groove. When the sliding block 642 moves downward to the horizontal section of the L-shaped groove 641, the plug-in block 640 is inserted into the plug-in groove, so that the rib plate 60, the plug-in block 640, the upper mold 5 and the base 1 together form a stable rectangular frame.

[0046] like Figure 4 and Figure 5 As shown, four sliding rods 67 with a rectangular arrangement and a vertical axis are slidingly provided on the rib plate 60, and the inner and outer caressing plates 61 and 62 are fixedly provided on the lower end surfaces of the two sliding rods 67 on the left and right sides respectively. A compression spring 670 which is sleeved on the sliding rod 67 is fixedly provided between the inner and outer caressing plates 61 and 62 and the rib plate 60.

[0047] like Figure 6 As shown, in order to reduce the friction during the left-right reciprocating smoothing process and reduce the wear on the aluminum plate, the opposite surfaces of the inner smoothing plate 61 and the adjacent outer smoothing plate 62 are both rotatably provided with a plurality of smoothing rollers 671 equidistantly arranged from left to right and with vertical axes, and the lower ends of the smoothing rollers 671 are chamfered.

[0048] like Figure 4 、 Figure 5 and Figure 6 As shown, the support portion 64 also includes a vertical groove 645. The upper end surface of the vertical section of the lower mold 3 is provided with a vertical groove 645. The upper end opening of the vertical groove 645 is chamfered. A support plate 646 is fixedly provided on the lower end surface of the outer caressing plate 62. The front and rear sides of the support plate 646 are provided with a plurality of laminating rollers 647 arranged from left to right and with vertical axes. The lower end surface of the support plate 646 is provided with a plurality of bottoming rollers 648 arranged from left to right and with axes extending from front to back.

[0049] like Figure 5 and Figure 6 As shown, a triangular supporting transverse plate 649 is fixedly provided on the lower end surface of the inner comfort plate 61, and the supporting transverse plate 649 fits with the inclined surface of the upper mold 5.

[0050] During operation, after the upper mold 5 moves down to complete the stamping action, the upper mold 5 stops moving (maintaining the state in the lower mold 3), the cylinder works to make the lifting plate 66 move down, the sliding block 642 and the two ribs 60 move down synchronously to the horizontal section of the L-shaped groove 641, and during the above-mentioned downward movement, the rib 60 drives the inner and outer caressing plates 61 and 62 to move down synchronously, the inner caressing plate 61 drives the supporting cross plate 649 thereon to contact the corresponding inclined surface of the upper mold 5, and the outer caressing plate 62 drives the supporting plate 646 to move down into the corresponding vertical groove 645, and makes the bottom roller 648 contact the bottom of the vertical groove 645. It should be additionally explained at this time that after the supporting plate 646 enters the vertical groove 645, a self-locking state is formed between the lower mold 3, the outer caressing plate 62 and the upper mold 5 to improve the stability during the smoothing process, and the rib 60 continues to move down until it is flush with the horizontal section of the L-shaped groove 641, and the compression spring 6 70 deformation, the elastic force generated by the deformation of the compression spring 670 makes the outer caress plate 62 and the inner caress plate 61 have a downward force, so the inner caress plate 61 presses the inclined surface of the upper mold 5 through the supporting cross plate 649, and the inner caress plate 61 presses the lower mold 3 through the supporting plate 646, and improves the stability of the lower part of the outer caress plate 62 and the inner caress plate 61 through elastic compression, avoiding the instability problem caused by the outer caress plate 62 and the inner caress plate 61 only having the upper end connected to form a cantilever structure during the smoothing process. At the same time, the plug-in block 640 is inserted into the plug-in groove to avoid the cantilever beam problem of the rib plate 60, and at the same time, the rib plate 60, the locking part 65, the plug-in block 640, the inner caress plate 61, the outer caress plate 62, the upper mold 5, the lower mold 3 and the base together form a plurality of rectangular frames, which improves the stability during the smoothing process and improves the alignment accuracy of the smoothing route with the length direction of the aluminum plate to ensure the smoothing effect.

[0051] It should be additionally explained that the provision of the laminating roller 647 and the bottoming roller 648 enables the support plate 646 and the lower mold 3 to be in rolling contact, thereby reducing the impact of the friction between the support plate 646 and the lower mold 3 on the left and right movement of the outer caressing plate 62. Secondly, the provision of the smoothing roller 671 reduces the friction between the outer caressing plate 62 or the inner caressing plate 61 and the aluminum plate while protecting the surface of the aluminum plate to avoid surface scratches caused by the smoothing action.

[0052] like Figure 4 and Figure 5 As shown, a follow-up slider 651 is provided on the upper mold 5 for sliding left and right. The follow-up slider 651 passes through the upper mold 5 front and back. The left end face of the follow-up slider 651 is provided with two accommodating grooves 652 which are symmetrical front and back and have a T-shaped cross-section in the left and right directions. A rib 653 is welded and installed on the upper end face of the rib 60. The upper end of the rib 653 is close to the upper mold 5 as a T-shaped section. The T-shaped section of the rib 653 is inserted into the corresponding accommodating groove 652 so that the front and rear ribs 60 are supported as a whole by the follow-up slider 651.

[0053] like Figure 4 and Figure 5 As shown, a locking block 654 is provided on the upper end surface of the follower slider 651 for sliding up and down. The locking block 654 penetrates into the corresponding receiving groove 652. When the locking block 654 falls due to its own weight, the matching state of the corresponding rib 653 and the receiving groove 652 is locked.

[0054] After the sliding block 642 and the rib plate 60 move to the horizontal section of the L-shaped groove 641, the handle is manually pushed to move the rib plate 60 to the right, and the locking block 654 is manually moved up so that the rib plate 60 drives the T-shaped section of the rib 653 to move into the corresponding receiving groove 652, and the locking block 654 is released. The locking block 654 moves down and locks the front and rear ribs 653. At this point, the two rib plates 60 are supported by the corresponding ribs 653 as cantilever beams. The support of the upper ribs 653 and the plug-in matching process of the lower plug-in block 640 prevent the rib plate 60 from forming a cantilever beam structure. At the same time, the horizontal state of the rib plate 60 is maintained to prevent the rib plate 60 from deviating from the horizontal due to installation deviation and affecting the operating effect of the inner and outer caressing plates 61 and 62. Then, the rib plate 60 is moved back and forth left and right. Secondly, when the operation is completed, the locking block 654 is manually moved up to unlock the rib plate 60.

[0055] like Figure 4 、 Figure 7 and Figure 8 As shown, the locking portion 65 includes an operating rod 650 with an axis extending from front to back, and the operating rod 650 is rotatably set on the plug-in block 640. The end surface of the operating rod 650 away from the upper mold 5 is fixedly provided with a shift rod 656 that passes through the top of the rib 60. A plate group corresponding to the outer caress plate 62 and the inner caress plate 61 is fixedly provided on the operating rod 650, and the plate group includes two left-right symmetrical ear plates 657. The inner caress plate 61 and the outer caress plate 62 are provided with mounting grooves 658 for the ear plates 657 and the operating rod 650 to move forward and backward. The inner caress plate 61 and the outer caress plate 62 are provided with a card slot 659 located in the middle position of the mounting groove 658 in the front-back direction.

[0056] like Figure 7 and Figure 8 As shown, in order to facilitate the ear plate 657 to rotate and snap into the slot 659, the adjacent inner parts of the mounting slot 658 and the slot 659 are chamfered.

[0057] After the rib 653 is inserted into the receiving groove 652, the lever 656 is manually toggled to rotate the operating rod 650 to the left, and the operating rod 650 drives the ear plate 657 thereon to rotate synchronously. The ear plate 657 gradually squeezes into the corresponding slot 659 during the rotation process, and finally the ear plate 657 is inserted into the slot 659. At this time, a rectangular frame with a strictly limited front and rear distance is formed between the inner and outer caressing plates 61 and 62 and the rib plate 60. At the same time, the inner and outer caressing plates 61 and 62 have a tendency to squeeze the aluminum plate, thereby improving the smoothing effect and avoiding the problem of insufficient smoothing effect on the aluminum plate caused by the cantilever structure formed at the lower end of the inner and outer caressing plates 61 and 62. Then, the smoothing action is performed again. After the smoothing action is completed, the lever 656 is manually toggled to reset the operating rod 650, so as to facilitate the upward movement and reset of the rib plate 60, the inner and outer caressing plates 61 and 62.
