Description

Technical Field

[0001] This utility model relates to the field of stamping technology, and in particular to a stable and durable lighter casing forming machine. Background Technology

[0002] As the core protective and supporting component of a lighter, the quality of its molding directly affects the structural stability and safety of the lighter. The lighter casing is produced using a metal sheet stamping process, relying on a stamping device to press and shape the metal sheet. If manual loading, positioning, and unloading are used, the hand movements of the worker holding the metal sheet to the designated stamping position are easily affected by factors such as tremors and visual judgment errors, leading to inconsistent positioning accuracy. After stamping, workers need to manually move the metal sheet outwards to move the formed casing towards the collection frame for unloading. After unloading, the metal sheet needs to be pushed in the opposite direction and moved a specified distance to prepare for the next stamping. The entire loading, unloading, and resetting process requires multiple movements of the metal sheet, making the operation cumbersome and affecting production quality and efficiency. Furthermore, the repeated manual movement of the metal sheet requires the worker's hands to frequently approach the working area of ​​the stamping device, posing certain safety hazards.

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0026] Example 1 Reference Figures 1-3 This is the first embodiment of the present invention, which provides a stable and durable lighter shell forming machine. The stable and durable lighter shell forming machine includes a main component 1, including a worktable 11. A lower mold 12 is provided on the worktable 11, and an upper mold 13 is provided above the lower mold 12. The lower mold 12 has a groove, and the upper mold 13 has a corresponding protrusion, so that the metal sheet 3 can be stamped into a hollow cylindrical shell. A material ejector is provided in the lower mold 12. After stamping, the material ejector pushes upward, lifting the formed lighter shell upward. At this time, the bottom of the formed shell will be flush with the upper surface of the lower mold 12, which is convenient for subsequent unloading. A lifting platform 14 is fixed on the upper mold 13. The lifting platform 14 is hydraulically driven to complete the lifting and moving. A frame 15 is fixed on the worktable 11. During stamping, the upper mold 13 moves downward and finally fits tightly with the lower mold 12 to stamp the metal sheet 3. This is the prior art, and this solution will not be described in detail. Moreover, those skilled in the art can clearly understand the working principle.

[0027] Auxiliary component 2, located on workbench 11, includes multi-stage cylinder 21. The stroke of multi-stage cylinder 21 is controllable. A push plate 211 is fixed to the extended end of multi-stage cylinder 21. By controlling the unit movement stroke of multi-stage cylinder 21, the push plate 211 can be moved, thereby moving the metal sheet 3 to a certain position. A discharge component 22 is provided on one side of multi-stage cylinder 21. By setting the discharge component 22, the formed shell can be automatically discharged.

[0028] The unloading component 22 includes a movable frame 221 located on one side of the lower mold 12. The movable frame 221 is U-shaped, and the size of the groove formed in the middle of the movable frame 221 corresponds to that of the metal sheet 3, thereby restricting the position of the metal sheet 3. When the multi-stage cylinder 21 pushes the metal sheet 3 to move, the metal sheet 3 will slide on the movable frame 221. A movable column 222 is fixed on one side of the movable frame 221. A rotating sleeve 223 is fitted over the movable column 222. A spiral groove 222-1 is opened on the movable column 222. A slider 224 is fixed on the rotating sleeve 223. The slider 224 slides in the spiral groove 222-1.

[0029] When the rotating sleeve 223 rotates, the rotation of the moving column 222 is restricted. At this time, the slider 224 will slide in the spiral groove 222-1, thereby driving the moving column 222 to move along the axial direction of the rotating sleeve 223, thereby driving the moving frame 221 to move, and then driving the metal sheet 3 to move in a position perpendicular to the feeding direction.

[0030] During stamping, a portion of the metal sheet 3 will be cut off to form a through hole. The size of the formed shell will be smaller than the through hole. At the same time, under the action of the lifting mechanism inside the lower die 12, the bottom of the formed shell will be flush with the upper surface of the lower die 12. When the metal sheet 3 moves in a position perpendicular to the feeding direction, the inner wall of the through hole will push the formed shell to move away from the lower die 12. Finally, the formed shell will fall through the through hole, thus completing the unloading.

[0031] Example 2 Reference Figures 1-6 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0032] Specifically, a positioning frame 23 is also fixed on the workbench 11. The positioning frame 23 is U-shaped and a support plate is fixed at the bottom of the positioning frame 23. The positioning frame 23 is fixed on the workbench 11 by the support plate. The positioning frame 23 is set to ensure that the metal sheet 3 can be kept horizontal when it is pushed and fed. The size of the positioning frame 23 corresponds to the thickness of the metal sheet 3.

[0033] The size of the push plate 211 is smaller than the distance between the positioning frames 23 in the same group.

[0034] Specifically, there are multiple sets of positioning frames 23, each set including two positioning frames 23. The two sets of positioning frames 23 closer to the lower mold 12 are narrower. The positioning frames 23 can ensure that the metal sheet 3 moves horizontally. At the same time, the metal sheet 3 can also slide within the positioning frames 23 during unloading.

[0035] At the contact point between the positioning frame 23 and the metal sheet 3, several friction blocks are provided to increase the friction between them. The metal sheet 3 will only change position under a large external force.

[0036] Before stamping, the multi-stage cylinder 21 extends to its shortest distance, then inserts the metal sheet 3 into the positioning frame 23 and places the metal sheet 3 on the moving frame 221. Before each stamping, the multi-stage cylinder 21 is started, pushing the metal sheet 3 to a designated position and then stopping. After stamping is completed, it is started again.

[0037] Specifically, the auxiliary component 2 also includes a trigger 24, which is located on one side of the lifting platform 14. The trigger 24 is located so that the lifting and moving of the lifting platform 14 can trigger the unloading component 22 to complete the unloading.

[0038] The trigger 24 includes a rotating plate 241 fixed on the rotating sleeve 223. A groove 241-1 is provided on the rotating plate 241. A cylinder 242 is slidably arranged in the groove 241-1. A lifting plate 243 is fixed on one side of the cylinder 242.

[0039] In the initial state, the rotating plate 241 will be in an upward tilted position. When the lifting plate 243 moves downward, the cylinder 242 and the slide groove 241-1 cooperate to make the rotating plate 241 rotate downward, thereby driving the rotating sleeve 223 to rotate.

[0040] Specifically, the lifting plate 243 is covered with a lifting sleeve 244, which is fixed on the lifting platform 14. The lifting sleeve 244 has a lifting groove 244-1 inside, and the lifting plate 243 slides in the lifting groove 244-1. The relative position of the lifting plate 243 and the lifting platform 14 can be changed to ensure continuous and stable stamping.

[0041] Example 3 Reference Figures 1-4 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0042] Specifically, a spring 245 is fixed to one end of the lifting plate 243, and the other end of the spring 245 is fixed to the inner wall of the lifting groove 244-1. The spring 245 makes the lifting plate 243 and the lifting platform 14 elastically connected.

[0043] In the initial state, the lifting platform 14 drives the lifting sleeve 244 to move downward synchronously. At this time, the spring 245 will also push the lifting plate 243 downward, thereby causing the moving column 222 to move into the rotating sleeve 223. As the lower die 12 descends, when the lower die 12 approaches the position of contact with the metal sheet 3, the moving column 222 moves to the limit position in the rotating sleeve 223, hindering the further rotation of the rotating sleeve 223. Due to the setting of the spring 245, the spring 245 can be compressed, and the relative position of the lifting plate 243 and the lifting platform 14 changes, so as not to affect the continued descent of the lifting platform 14, thereby ensuring that the stamping can be carried out stably.

[0044] After the stamping is completed, the lifting platform 14 will move in the opposite direction, causing the lifting sleeve 244 to rotate upward. The spring 245 will return to its original position and extend. When the relative position of the lifting plate 243 and the lifting platform 14 returns to the initial position, the lifting plate 243 moves upward with the cooperation of the spring 245, and the cylinder 242 slides in the slide groove 241-1, causing the rotating plate 241 to rotate in the opposite direction, which in turn causes the rotating sleeve 223 to rotate in the opposite direction, thereby causing the moving column 222 to move in the opposite direction, thus pushing the formed shell away from the lower mold 12 and completing the unloading.

[0045] Specifically, the rotating sleeve 223 has bearings at both ends connected to support blocks 225, which are fixed on the worktable 11. The support blocks 225 are used to provide stable support for the rotating sleeve 223.

[0046] Specifically, the movable frame 221 is U-shaped, and a protrusion 226 is fixed at the bottom of the movable frame 221. A through groove 226-1 is opened in the protrusion 226. A fixing post 227 is fixed on the support block 225. The fixing post 227 slides in the through groove 226-1. Through the cooperation of the fixing post 227 and the through groove 226-1, the movable frame 221 and the movable post 222 are restricted from rotating.

[0047] Specifically, there are two sets of unloading parts 22, symmetrically distributed on both sides of the lower mold 12.

[0048] Specifically, the workbench 11 is equipped with an inclined plate 228. When the metal sheet 3 moves in a position perpendicular to the feeding direction, it pushes the formed shell away from the lower mold 12. Then, the formed lighter shell will fall along the inclined plate 228 into the collection area, completing the collection of the finished part.

[0049] During use, before stamping, the multi-stage cylinder 21 extends to its shortest distance, then the metal sheet 3 is inserted into the positioning frame 23 and placed on the moving frame 221. One end of the metal sheet 3 is in contact with the push plate 211. Before each stamping, the multi-stage cylinder 21 is activated to push the metal sheet 3 to a designated position and then stops. Afterwards, the lifting platform 14 drives the upper die 13 to move downwards, and the lifting sleeve 244 moves downwards simultaneously. At this time, the spring 245 also pushes the lifting plate 243 to move downwards, causing the cylinder 242 to move downwards. With the cooperation of the cylinder 242 and the slide 241-1, the rotating plate 241 rotates downwards, thereby driving the rotating sleeve 223 to rotate. The moving column 222 moves along the axis of the rotating sleeve 223, thereby driving the metal sheet 3 to the stamping position. Before the lower die 12 approaches the position where it is in contact with the metal sheet 3, the metal sheet 3 has reached the stamping position, and then the stamping begins.

[0050] After stamping, the lifting platform 14 moves the upper die 13 upward, and the ejector in the lower die 12 ejects the formed shell upward. The bottom of the formed shell is flush with the upper surface of the lower die 12 and is located in the through hole cut by the metal sheet 3. As the lifting platform 14 moves upward, the cylinder 242 slides in the slide groove 241-1, which drives the rotating plate 241 to rotate in the opposite direction, which in turn drives the rotating sleeve 223 to rotate in the opposite direction, thereby driving the moving column 222 to move in the opposite direction, pushing the formed shell away from the lower die 12. Then the formed shell will fall from the through hole cut by the metal sheet 3 onto the inclined plate 228, and then the shell will fall along the inclined plate 228 to the collection area, completing the collection of the finished part. Then the multi-stage cylinder 21 pushes the metal sheet 3 to move a unit distance, repeating the above operation, thereby improving the stamping production efficiency and accuracy of the lighter shell.

[0051] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
