Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, and in particular to a forming stamping die for the production of iron boxes with double-sided stamping. Background Technology

[0002] In the production process of tin boxes (such as food boxes, sealed boxes, industrial boxes, etc.), box shaping is a key process that determines the product's sealing and assembly performance. It requires applying pressure to the box body through stamping dies to correct the box body's flange width, verticality, roundness, shape, etc.

[0003] The specific principle of stamping dies for shaping boxes is to set the lower die as a contour die with corresponding concave or convex structures. The shape of the upper die corresponds to that of the lower die. During operation, the operator places one end of the box onto the lower die. When the upper and lower dies are closed, the concave or convex structures are used to shape and stamp the box. However, in current edge stamping and shaping of boxes, it is not possible to shape both sides of the box at once. After one stamping, the box needs to be removed, flipped, and placed back into the lower die to complete the shaping of both sides, which increases the workload of the operator.

[0004] Therefore, it is necessary to propose a new technical solution to address the above problems. Utility Model Content

[0005] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the aforementioned problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a double-sided stamping forming die for producing iron boxes, including a worktable, a power assembly mounted on the worktable, and a stamping head connected below the power assembly; The workbench is also equipped with a vertical plate. From top to bottom, a first upper module, a first lower module, a second upper module, and a second lower module are arranged on one side of the vertical plate. The first lower module and the second upper module can be combined and housed inside a box. The first upper module and the second upper module can be slidably mounted on the vertical plate. An elastic pressing member is provided between the first upper module and the second upper module and the upright plate. The elastic pressing member can push the first upper module and the second upper module to move upward. The first upper module and the second upper module can move up and down synchronously, and the upper end of the first upper module is higher than the upper end surface of the upright plate.

[0007] As a further embodiment of this utility model: a first movable block and a second movable block are respectively connected to the first upper module and the second upper module, and a first movable groove and a second movable groove are provided on the upright plate. The first movable block and the second movable block pass through the first movable groove and the second movable groove respectively, and the first movable block and the second movable block can move up and down in the first movable groove and the second movable groove respectively. The first movable block has a connecting rod at its lower end that is fixed to the second movable block, and the elastic pressing member is located at the lower end of the second movable block.

[0008] As a further embodiment of this utility model: an outer edge plate is also installed on one side of the workbench, and a pusher plate that can slide back and forth on the outer edge plate is provided with a box fixing groove on the side of the pusher plate facing the workbench.

[0009] As a further embodiment of this utility model: a slot is provided on the side of the upright plate away from the first upper module, the first movable block and the second movable block both extend into the slot, and the elastic pressing member is disposed between the second movable block and the bottom wall of the slot.

[0010] As a further embodiment of this utility model: a first guide rod is provided in the slot, and a first guide hole is provided on the second movable block, the first guide hole being guided and connected to the first guide rod.

[0011] As a further embodiment of this utility model: a slot is provided on the outer edge plate, and slide rails are installed on both sides inside the slot. Slider blocks that slide in cooperation with the slide rails are installed on both sides of the lower end of the pusher plate.

[0012] As a further embodiment of this utility model: a magnet block is embedded in the bottom wall of the box fixing groove.

[0013] As a further embodiment of this utility model: a second guide rod is installed on both sides of the upper end of the outer edge plate, and a guide block is provided on both sides of the pusher plate. A second guide hole is opened on the guide block, and the second guide hole is connected to the second guide rod in a guiding fit.

[0014] Compared with the prior art, the beneficial effects of this technical solution are as follows: In the initial state, the second upper module is merged with the first lower module by the upward push of the elastic pressing component, and the first upper module is in a state higher than the top of the upright plate. During operation, the end of the box that needs to be stamped and shaped is placed outside the first lower module and the second upper module. At this time, the lower side of the upper edge of the box is in contact with the first lower module, and the lower side of the lower edge is in contact with the second lower module. Then, the hydraulic cylinder is started, and the power column of the hydraulic cylinder drives the stamping head, so that the stamping head hits the first upper module. The first upper module and the second upper module are pressed down synchronously, thereby stamping and shaping the two sides of the box at the same time, improving work efficiency, eliminating the need for secondary stamping, and reducing workload. After a stamping is completed, the power column of the hydraulic cylinder drives the stamping head to move up and reset. At this time, the elastic push of the elastic pressing component causes the first upper module and the second upper module to move back to their initial positions. Furthermore, by first inserting the non-shaped end of the box into the box fixing groove of the pusher plate, and then pushing the pusher plate, the pusher plate slides towards the worktable on the outer edge plate, so that the end of the box that needs to be shaped fits over the outside of the first lower module and the second upper module. Then, the box is stamped and shaped. After the stamping is completed, the pusher plate is pulled outward, and the shaped box can be taken away and collected. This eliminates the need for workers to hold the box in their hands and place it into the mold. During the stamping process, there is no need to hold the box to stabilize it, thus avoiding the risk of hands being pinched and improving work safety.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-5 A double-sided stamping forming die for producing iron boxes includes a worktable 1, a power assembly 2 mounted on the worktable 1, a stamping head 21 connected below the power assembly 2, the power assembly 2 including a mounting bracket 22 mounted on the worktable 1, a hydraulic cylinder 23 mounted on the mounting bracket 22, and the telescopic power column of the hydraulic cylinder 23 connected to the stamping head 21. The workbench 1 is also equipped with a vertical plate 3. From top to bottom, a first upper module 4, a first lower module 5, a second upper module 6, and a second lower module 7 are arranged on one side of the vertical plate 3. The first lower module 5 and the second upper module 6 can be combined and housed in a box. The first upper module 4 and the second upper module 6 can be slidably installed on the vertical plate 3. An elastic pressing member 10 is provided between the first upper module 4 and the second upper module 6 and the upright plate 3. The elastic pressing member 10 can push the first upper module 4 and the second upper module 6 to move upward. The first upper module 4 and the second upper module 6 can move up and down synchronously, and the upper end of the first upper module 4 is higher than the upper end surface of the upright plate 3.

[0020] Specifically, in the initial state, the second upper module 6 is merged with the first lower module 5 by the upward push of the elastic pressing member 10, while the first upper module 4 is in a state higher than the upper end of the upright plate 3. During operation, the end of the box that needs to be stamped and shaped is placed outside the first lower module 5 and the second upper module 6. At this time, the lower side of the upper edge of the box is in contact with the first lower module 5, and the lower side of the lower edge is in contact with the second lower module 7. That is, there are gaps between the first upper module 4 and the first lower module 5, and between the second upper module 6 and the second lower module 7, which makes it convenient for the staff to put the box in. Then, the hydraulic cylinder 23 is started, and the power column of the hydraulic cylinder 23 drives the stamping head 21, so that the stamping head 21 hits the first upper module 4 until the first upper module 4 is flush with the upper end of the upright plate 3. At this time, the first upper module 4 and the second upper module 6 are pressed down synchronously, thereby stamping and shaping the two sides of the box at the same time, improving work efficiency, eliminating the need for secondary stamping, and reducing workload. After a stamping is completed, the power column of the hydraulic cylinder 23 drives the stamping head 21 to move upward and reset. At this time, the elastic push of the elastic pressing member 10 causes the first upper module 4 and the second upper module 6 to move upward back to their initial positions. In this embodiment, the shaping effect of the box edge is achieved by forming a concave structure on the inner edge of the first lower module 5 and the second upper module 6 near the upright plate 3, and forming an outward convex structure corresponding to the concave structure on the inner side of the first upper module 4 and the second lower module 7. When the first upper module 4 is pressed down, the cooperation between its outward convex structure and the concave structure in the first lower module 5 forms the effect of shaping the upper edge of the box. When the second upper module 6 is pressed down, the inner concave structure on its inner side cooperates with the outward convex structure of the second lower module 7 to form the effect of shaping the lower edge of the box. It should be noted that in the process of shaping the box edge, some boxes have different length and width frames, so it is necessary to use two stamping dies to stamp and shape the long side and short side of the box respectively. Preferably, a rubber pad (not shown in the figure) is provided at the lower end of the stamping head 21 to prevent the stamping head 21 from impacting the first upper module 4 and causing damage to the workpiece.

[0021] Based on the above embodiments, it is further proposed that a first movable block 41 and a second movable block 61 are respectively connected to the first upper module 4 and the second upper module 6, and a first movable groove 31 and a second movable groove 32 are opened on the upright plate 3. The first movable block 41 and the second movable block 61 pass through the first movable groove 31 and the second movable groove 32 respectively, and the first movable block 41 and the second movable block 61 can move up and down in the first movable groove 31 and the second movable groove 32 respectively. The first movable block 41 is provided with a connecting rod 42 fixedly connected to the second movable block 61 at its lower end, and the elastic pressing member 10 is provided at the lower end of the second movable block 61.

[0022] Specifically, by passing the first movable block 41 of the first upper module 4 through the first movable slot 31 opened on the vertical plate 3, and then passing the second movable block 61 of the second upper module 6 through the second movable slot 32 opened on the vertical plate 3, and then fixing the connecting rod 42 at the lower end of the first movable block 41 to the second movable block 61, the first upper module 4 and the second upper module can be raised and lowered synchronously. The widths of the first movable slot 31 and the second movable slot 32 are sufficient for the first movable block 41 and the second movable block to perform predetermined lifting and lowering ranges.

[0023] Furthermore, a slot 33 is provided on the side of the upright plate 3 away from the first upper module 4, and the first movable block 41 and the second movable block 61 both extend into the slot 33, and the elastic pressing member 10 is disposed between the second movable block 61 and the bottom wall of the slot 33.

[0024] Specifically, a slot 33 is made on the side of the upright plate 3 away from the first upper module 4 (i.e., the back side). The first movable block 41 and the second movable block 61 extend into the slot 33 through the first movable slot 31 and the second movable slot 32, respectively. Then, the elastic pressing member 10 is set on the bottom wall of the slot 33 and applies an upward thrust to the second movable block 61, so that the second movable block 61 and the first movable block 41 can move upward and reset.

[0025] Furthermore, a first guide rod 34 is provided in the slot 33, and a first guide hole 62 is provided on the second movable block 61. The first guide hole 62 is guided and connected with the first guide rod 34.

[0026] Specifically, the second movable block 61 is guided by the first guide hole 62 and the first guide rod 34 in the slot 33, so that the second movable block 61 remains vertical during the lifting and lowering movement, thus avoiding the displacement of the positions of the first upper module 4 and the second upper module 6, which would affect the shaping effect of the box.

[0027] Based on the above embodiments, it is further proposed that an outer edge plate 8 is also installed on one side of the workbench 1, and a pusher plate 9 that can slide back and forth on the outer edge plate 8 is provided. The pusher plate 9 has a box fixing groove 91 on the side facing the workbench 1.

[0028] Specifically, the unshaped end of the box is first inserted into the box fixing groove 91 of the pusher plate 9, and then the pusher plate 9 is pushed. The pusher plate 9 slides on the outer edge plate 8 toward the worktable 1, so that the end of the box that needs to be shaped is fitted onto the outside of the first lower module 5 and the second upper module 6. Then, the box is stamped and shaped. After the stamping is completed, the pusher plate 9 is pulled outward, and the shaped box can be taken away and collected. This eliminates the need for workers to hold the box in their hands and place it into the mold. During the stamping process, there is no need to hold the box to stabilize it, thus avoiding the risk of hands being pinched and improving work safety.

[0029] Furthermore, a slot 81 is provided on the outer edge plate 8, and slide rails 82 are installed on both sides inside the slot 81. Slider blocks 92 that slide in cooperation with the slide rails 82 are installed on both sides of the lower end of the push plate 9.

[0030] Specifically, a slot 81 is made on the outer edge plate 8, and a slide rail 82 is installed in the slot 81 so that the slider 92 at the lower end of the pusher plate 9 is slidably connected with the slide rail, so that the pusher plate 9 can slide back and forth on the outer edge plate 8.

[0031] Furthermore, a magnet block 93 is embedded in the bottom wall of the box fixing groove 91.

[0032] Specifically, the box body is attracted by the embedded magnet 93, thereby fixing one end of the box body in the box body fixing groove 91.

[0033] Furthermore, a second guide rod 83 is installed on both sides of the upper end of the outer edge plate 8, and a guide block 94 is provided on both sides of the push plate 9. A second guide hole 95 is opened on the guide block 94, and the second guide hole 95 is connected to the second guide rod 83 for guidance.

[0034] Specifically, the guide blocks 94 on both sides of the pusher plate 9 are guided and fitted onto the second guide rod 83 through the second guide hole 95, thereby improving the stability of the pusher plate 9 when sliding back and forth and avoiding deviation during sliding.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
