Description

Technical Field

[0001] The invention relates to aluminum material packaging and processing equipment, and more specifically, to a multi-station aluminum material forming device and also to an aluminum material packaging and processing method. Background Art

[0002] In the manufacturing process of today's aluminum packaging materials, aluminum sheets need to be processed by extrusion machines. This process involves continuous extrusion and stretching of the sheet, so that it can be shaped into various parts such as covers. However, for end caps that are both slender and have a large depth, they usually require a series of continuous forming processes to gradually and progressively stretch them to the predetermined shape specifications.

[0003] During the forming process, the aluminum workpiece needs to be transferred between the front and rear forming positions, where a mold frame is installed, and the corresponding mold is installed on the mold frame. After the forming step is completed, the aluminum workpiece is ejected to the upper side of the upper mold, and is grabbed by the gripper assembly in conjunction with the tooling, and then transferred to the next forming position through the transverse structure, and the workpiece is placed on the next mold frame for processing. During the transfer process, due to the transverse movement of the gripper assembly, friction may occur between the lower side of the workpiece and the upper surface of the mold frame, forming resistance during the transfer process, which may easily cause the workpiece to fall off from the gripper assembly. Even the mold frames at the front and rear forming positions have a certain height difference. When the workpiece is transferred to the next mold frame, the lower part of the workpiece will collide and interfere with the upper side of the mold frame, which will directly cause the workpiece to be collided and fall off, and may even cause the equipment to jam, affecting the operating stability and continuity of the equipment.

DETAILED DESCRIPTION

[0033] 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.

[0034] This embodiment discloses a multi-station aluminum material forming device. Figure 1-6As shown, it includes a workbench 1, a transverse frame 4 and a plurality of gripper assemblies 5. The workbench 1 is evenly provided with a plurality of forming positions 2 along the transverse direction, and at each forming position 2, the aluminum workpiece can be formed by upper and lower pressures.

[0035] Each forming position 2 is provided with a lower die frame 21, and the lower die frame 21 is used to install the lower die tooling. A hydraulic cylinder 3 is provided directly above the forming position 2, and an upper die frame 31 is installed at the lower output end of the hydraulic cylinder 3, and the upper die frame 31 is directly opposite to the lower die frame 21. The upper die frame 311 and the lower die frame 2 are respectively installed with appropriate molds, which can realize the forming process of the workpiece, and multiple forming positions 2 can realize continuous multi-process processing.

[0036] The traverse frame 4 is a long rod-shaped structure, located on the upper part of the workbench 1, and supported by a slide rail and a rolling support structure. The traverse frame 4 can be slidably connected to the workbench 1 along the distribution direction of each molding position 2, and can be reciprocally driven to slide by a driver.

[0037] Each gripper assembly 5 is mounted on the transverse frame 4 and corresponds to the molding position 2 one by one. It can slide along with the transverse frame 4 to grab the workpiece on the lower mold frame 21. The gripper assembly 5 can grab the workpiece to be processed, and follow the reciprocating forward and backward movement of the transverse frame 4 to deliver the processed workpiece in sequence and realize continuous multi-pass processing. The transverse frame 4 has a forward direction and a backward direction during the reciprocating sliding process. For details, refer to Figure 4 , Figure 6 direction shown.

[0038] Reference Figure 3 , Figure 4 , Figure 5 As shown, the gripper assembly 5 includes a gripper bracket 51 and a finger cylinder 52. The gripper bracket 51 is installed on the upper part of the transverse frame 4, and the gripper bracket 51 extends toward the transverse frame 4. The finger cylinder 52 is fixedly installed on the upper side of the gripper bracket 51, and the output end of the finger cylinder 52 extends toward the corresponding forming position 2, and can be installed with a workpiece fixture. The workpiece fixture can be specifically designed according to the workpiece structure of each production process, and can realize the gripping of the workpiece.

[0039] The gripper bracket 51 is rotatably connected to the transverse frame 4 via the rotating shaft 511, which can realize the up and down swing of the gripper assembly 5. During the swinging process, the workpiece clamp installed at the output end of the finger cylinder 52 can realize the up and down swinging, thereby realizing the swing avoidance of the workpiece and the upper side of the lower mold frame 21.

[0040] The axis direction of the rotating shaft 511 is consistent with the sliding direction of the transverse frame 4. The rotating shaft 511 of the gripper bracket 51 extends from both sides, and the two sides are rotatably supported by the first shaft seat 8 and the second shaft seat 9 respectively, and the output end of the finger cylinder 52 can swing up and down with the gripper bracket 51.

[0041] Reference Figure 4 , Figure 5 As shown, the finger cylinder 52 is fixedly installed on the gripper bracket 51, and the gripper bracket 51 can swing along with the gripper bracket 51. During the up and down swinging process, the workpiece of the finger cylinder 52 can give way to the upper side of the lower mold frame 21.

[0042] During the process of the gripper assembly 5 grasping the workpiece and moving it horizontally, the output end of the finger cylinder 52 can move upward, so that the grasped workpiece can move upward, and the workpiece grasped by the finger cylinder 52 can avoid each other with the upper side of the lower mold frame 21, avoiding the workpiece from interfering with the upper side of the next lower mold frame 21. Especially when there is a slight height difference between the lower mold frames 21, the avoidance action during the horizontal movement of the workpiece can be achieved.

[0043] Reference Figure 5 As shown, a limiting plane 512 is provided at the lower part of the gripper bracket 51, and the limiting plane 512 is located at the lower side of the rotating shaft 511, and the limiting plane 512 is located on the side of the rotating shaft 511 close to the forming position 2. The limiting plane 512 can be offset against the upper and lower parts of the transverse frame 4 to achieve limiting. Under the action of the gripper bracket 51, the finger cylinder 52, and the deadweight of the workpiece gripped by the finger cylinder 52, the limiting plane 512 can be offset against the upper side of the transverse frame 4, thereby limiting the position of the gripper assembly 5, and maintaining the gripper assembly 5 in a relatively balanced state. After the gripper assembly 5 is deflected, the side that grips the workpiece moves upward, and the limiting plane 512 is separated from the upper side of the transverse frame 4.

[0044] In order to achieve the deflection and avoidance of the gripper assembly 5 during the transverse movement of the transverse frame 4, a linkage assembly is arranged between the gripper bracket 51 and the workbench 1. The linkage assembly is used to limit the linkage of the gripper assembly 5, and can drive the gripper assembly 5 to swing up and down during the reciprocating transverse movement of the transverse frame 4. When the gripper assembly 5 grabs the workpiece from the current forming position 2 and moves to the next forming position 2, the linkage assembly will produce a deflection linkage action on the gripper assembly 5, and the side of the gripper assembly 5 grabbing the workpiece can produce a slight upward deflection, so that the workpiece grabbed by the gripper assembly 5 can rise, and a certain gap is generated between the gripper assembly 5 and the upper side of the lower mold frame 21, so as to avoid interference and collision between the upper side of the lower mold frame 21 and the workpiece, and avoid the workpiece falling and the stretching equipment jamming.

[0045] Reference Figure 4 , Figure 5 , Figure 6As shown, the linkage assembly includes a linkage rod 6 and a linkage runway 7, wherein the linkage rod 6 is fixedly connected to the gripper bracket 51, and the linkage runway 7 is fixedly installed on the workbench 1 and arranged along the sliding direction of the transverse frame 4. The transverse frame 4 is provided with a clearance groove 41 for the linkage rod 6 to pass through, and the clearance groove 41 can adapt to the swinging movement of the linkage end 61. The linkage rod 6 has a linkage end 61, which is the lower end of the linkage rod 6, and the linkage end 61 can be mutually linked with the linkage runway 7.

[0046] Reference Figure 6 As shown, the linkage runway 7 includes a convex edge 71, which is located on the side of the linkage end 61 facing away from the forming position 2 and between the linkage rod 6 and the rotating shaft 511. The working surface of the convex edge 71 is a side surface arranged toward the linkage rod 6, and has a recessed portion 711 and a raised portion 712, wherein the recessed portion 711 is recessed away from the linkage rod 6, and the raised portion 712 is raised toward the linkage rod 6; a horizontal guide surface 713 is formed between the raised portion 712 and the recessed portion 711, forming an inclined smooth transition, and the raised portion 712 is used to push the linkage rod 6 to swing toward the forming position 2, and drive the gripper assembly 5 to swing upward near the forming position 2.

[0047] The convex portion 71 is located between the two forming positions 2, and the position of the convex portion 71 near the two forming positions 2 forms a horizontal guide surface 713; the recessed portion 711 corresponds to the forming position 2. Among them, the horizontal guide surface 713 of the convex portion 71 in the backward direction contacts the linkage rod 6 at the current position. When the gripper assembly 5 starts to move horizontally, the linkage rod 6 on the lower side of the gripper assembly 5 immediately presses against the horizontal guide surface 713, and can be immediately pushed by the horizontal guide surface 713 to produce a swing, so that the workpiece can give way and separate from the current lower mold frame 21, reducing the friction on the upper side of the lower mold frame 21. When the gripper assembly 5 approaches the next lower mold frame 21, it is still in a swinging state, and the workpiece is still slightly higher than the lower mold frame 21, so that the workpiece can move smoothly to the upper side of the lower mold frame 21. When reaching the end position in the forward direction, the horizontal guide surface 713 of the convex portion 71 in the forward direction is slid back to the recessed portion 711. When the linkage rod 6 is at the recessed portion 711 , the gripper assembly 5 is in an initial state, and the limiting plane 512 can abut against the upper side of the transverse frame 4 , thereby limiting the position of the gripper assembly 5 .

[0048] Furthermore, the gripper assembly 5 can not only tilt and deflect around the rotating shaft 511, but also swing in the left and right directions. After the swing, the side facing the forward direction can tilt upward, so that the side of the workpiece in the forward direction can be further raised and can make way more smoothly. After the left and right swing, the front side of the workpiece is higher and can enter the upper side of the next lower mold frame 21. In the subsequent moving process, even if the lower side of the workpiece contacts the upper side of the lower mold frame 21, the workpiece can still be smoothly moved to the top of the next lower mold frame 21 under the guiding effect of the inclined surface of the lower side of the workpiece.

[0049] Reference Figure 4 As shown, the rotating shaft 511 is rotatably supported on the first shaft seat 8 through the first ball bearing 81, and the second shaft seat 9 is provided with a lifting groove 91, and a lifting block 92 is slidably connected in the lifting groove 91, and the rotating shaft 511 is rotatably supported on the lifting block 92 through the second ball bearing 93. The first ball bearing 81 and the second ball bearing 93 on both sides can not only allow the rotating shaft 511 to rotate, but also ensure that the two ends can produce an upward and downward offset, and the rotating shaft 511 can still rotate smoothly after the offset. Moreover, the lifting block 92 can not only slide up and down in the lifting groove 91, but also produce a slight movement in the left and right directions, thereby compensating for the slight offset of the two ends of the rotating shaft 511 in the lateral direction.

[0050] Reference Figure 4 As shown, the transverse frame 4 has a forward direction and a backward direction during the reciprocating sliding process, and the second shaft seat 9 is located in the forward direction relative to the first shaft seat 8; the linkage rod 6 is fixedly connected to the lower side of the gripper bracket 51 near the second shaft seat 9. When the linkage end 61 of the linkage rod 6 is not subjected to an upward force, the gripper bracket 51 and the transverse frame 4 are abutted against each other, so that the gripper assembly 5 can be kept in a stable state; when adjustment is required, the linkage runway 7 can apply an upward force to the linkage end 61 of the linkage rod 6, so that the side of the gripper assembly 5 facing the forward direction can be deflected upward, so as to achieve the supplementary deflection and displacement of the gripper assembly 5.

[0051] The linkage runway 7 includes a bottom portion 72, which is located directly below the linkage end 61, and the side of the bottom portion 72 facing upward is a working surface. On the working surface of the bottom portion 72, there are a high portion 722 protruding upward and a low portion 721 concave downward, which are distributed along the direction of the linkage runway 7.

[0052] An upper and lower guide surface 723 is formed between the high portion 722 and the low portion 721, forming an inclined smooth transition, so that the linkage rod 6 can smoothly switch and move between the high portion 722 and the low portion 721. When the linkage rod 6 moves to the high portion 722, the high portion 722 protrudes upward, which can push the linkage rod 6 to move upward. The linkage rod 6 can drive the rotating shaft 511 at one end to deflect up and down within the range of the lifting slot 91, so that the linkage rod 6 can push the axial side of the gripper bracket 51 to deflect upward, thereby causing the entire gripper assembly 5 to deflect, and the workpiece grasped by the gripper assembly 5 will also produce a corresponding deflection, and the side facing the forward direction is upward.

[0053] Reference Figure 6 As shown, the high portion 722 is located between the two molding positions 2 , and the high portion 722 forms upper and lower guide surfaces 723 near the two molding positions 2 , and the low portion 721 corresponds to the molding positions 2 .

[0054] Figure 6 The position of the linkage rod 6 is the end in the backward direction, that is, the state in which the gripper assembly 5 has not moved. In the subsequent movement process, the linkage rod 6 will first move on the upper part of the low-position portion 721. The low-position portion 721 will not produce an upward pressure on the linkage rod 6, and the axial ends of the gripper assembly 5 will not produce a deflection. The linkage rod 6 is first affected by the horizontal guide surface 713, and first rotates around the rotating shaft, so that the gripper assembly 5 can produce a slight upward movement until the linkage rod 6 moves to the position of the raised portion 712; at this time, the linkage rod 6 is still in the low-position portion 721, and then as it continues to move horizontally in the forward direction, the linkage rod 6 will gradually move to the upper and lower guide surfaces 723 and the high-position portion 722, and the linkage rod 6 will move upward, so that The two ends of the rotating shaft of the gripper assembly 5 will produce up and down deflection, and the side facing the forward direction will be in a high position, so that the bottom surface of one side of the workpiece in the forward direction can be deflected upward to further make room; then, the linkage rod 6 continues to move forward until it moves to the end close to the forward direction. At this time, the gripper assembly 5 and the workpiece have moved to the top of the lower mold frame 21 of the next forming position 2, and the position of the linkage rod 6 in the linkage runway 7 is located in the recessed portion 711 and the low portion 721. The gripper assembly 5 deflects in the opposite direction and returns to its original position, so that the workpiece grasped by the gripper assembly 5 can be replaced on the top of the lower mold frame 21 of the next forming position 2, so that the bottom of the workpiece can be close to and fit with the upper side of the lower mold frame 21 again, thereby maintaining the stability of the workpiece placement.

[0055] Then, the gripper assembly 5 and the linkage rod 6 will move in the opposite direction following the transverse moving frame 4, move in the backward direction, and retreat to the area of ​​the previous forming position 2 again.

[0056] Furthermore, the linkage runway 7 and the workbench 1 are detachable structures and are fixed by bolts; the linkage runway 7 can be adjusted along the sliding direction of the transverse frame 4, and then the positions corresponding to the forming positions 2 on the linkage runway 7 can be adjusted, and the linkage positions on the linkage runway 7 can be fine-tuned, and then the linkage amount of the linkage runway 7 with the gripper assembly 5 and the linkage rod 6 can be adjusted to adapt the linkage action to the fit of the production action. After the adjustment is completed, the linkage runway 7 is locked and fixed on the workbench 1 by bolts.

[0057] In addition, the upper end of the linkage rod 6 is plugged and fixed on the lower side of the gripper bracket 51, and the linkage rod 6 can be replaced. The length and diameter of the linkage rod 6 can be selected so that the linkage action of the linkage rod 6 and the linkage runway 7 can adapt to the action requirements of the equipment.

[0058] This embodiment also discloses an aluminum packaging processing method, which uses the multi-station aluminum forming device as mentioned above to produce aluminum packaging bottle components.

All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
