Description

Technical Field

[0001] This utility model relates to the field of stamping technology, specifically to a metal bottle cap stamping equipment with an easy-to-remove lower die. Background Technology

[0002] In the traditional bottle cap processing flow, strip metal sheets are used as the initial raw material. The stamping process is carried out in two steps. In the first step, the worker holds the strip metal sheet and moves and positions it segment by segment according to the set interval. The stamping equipment completes the initial stamping point by point on the sheet metal sheet, forming a batch of sheet-shaped cap blanks. In the second step, the formed sheet-shaped cap blanks are sent to the subsequent stamping process. After secondary stamping, edge rolling and other processes, they are finally formed into bottle caps. In this process, the stable conveying and precise positioning of the sheet metal sheet are the key to ensuring the dimensional accuracy of the cap blanks. The smooth demolding of the cap blanks after stamping directly affects the production efficiency. Therefore, there are high requirements for the limiting performance and unloading effect of the stamping equipment.

[0003] In the existing technology, this type of metal bottle cap stamping equipment has two obvious shortcomings: First, the strip material plate lacks a reliable limit adjustment structure during the stamping process, and relies solely on manual support and movement by workers. This is prone to deviation due to hand tremors or uneven force, resulting in stamping position deviation, which in turn leads to quality problems such as incorrect cap blank size and irregular edges, increasing the scrap rate. Second, after the cap blank is stamped, it often gets stuck in the cylinder due to friction or adsorption with the inner wall of the stamping cylinder, making it difficult to remove. It requires manual removal of the cap blank from the stamping cylinder, which not only reduces production efficiency but may also scratch the surface of the cap blank or cause hand injuries to workers during the removal process, posing a safety hazard. Utility Model Content

[0004] To address the technical deficiencies in the background art, this utility model proposes a metal bottle cap stamping equipment with an easily removable lower die. To further solve the aforementioned technical problems and meet practical needs, the specific technical solution is as follows: A metal bottle cap stamping device with easy unloading of the lower die includes a base plate and a stamping assembly mounted on the base plate. The base plate has symmetrically arranged limit adjustment components on the left and right sides of the stamping assembly. The limit adjustment components include a sliding rail, a sliding seat symmetrically arranged in the sliding rail, a rack arranged in the sliding rail and connected to the base plate, a limit fixing component arranged on the sliding seat and capable of engaging with the rack for limit positioning, and a limit upright plate arranged on the top of the sliding seat. The stamping assembly includes a lower die base arranged between the sliding rails, a stamping cylinder arranged in the lower die base, and a stamping head arranged directly above the stamping cylinder and capable of cooperating with the stamping cylinder for stamping. The stamping cylinder has a liftable top plate inside.

[0005] As a further technical solution of this utility model, the sliding rail includes a wall panel symmetrically erected in an inverted L shape on the upper surface of the base plate, a sliding channel formed by the wall panel and the base plate, and the rack is disposed in the sliding seat and connected to the upper surface of the base plate.

[0006] As a further technical solution of this utility model, sliding blocks are symmetrically arranged on the left and right sides of the sliding seat, the sliding seat is disposed inside the sliding seat and the sliding blocks of the sliding seat cooperate with the sliding rail to slide.

[0007] As a further technical solution of this utility model, the bottom of the sliding seat is provided with a limiting groove, the rack is placed in the limiting groove, the longitudinal direction of the limiting fixing member is provided inside one end of the sliding seat, one end of the limiting fixing member is placed above the sliding seat, and the other end of the limiting fixing member is placed in the limiting groove and engages with the rack.

[0008] As a further technical solution of this utility model, the limiting and fixing component includes a lifting rod that is placed outside the limiting plate and can be raised and lowered, which is longitudinally inserted inside the sliding seat; a limiting pressure plate that is disposed in the limiting through groove of the sliding seat and connected to the lower end of the lifting rod; and a first spring that is disposed in the limiting through groove and sleeved outside the lifting rod. One end of the first spring is connected to the top side wall of the limiting through groove, and the other end of the first spring is connected to the upper surface of the limiting pressure plate.

[0009] As a further technical solution of this utility model, the upper surface of the rack is provided with a first biting tooth, and the lower surface of the limiting pressure plate is provided with a second biting tooth that can bite with the first biting tooth.

[0010] As a further technical solution of this utility model, the stamping assembly also includes a mounting bracket disposed on the rear side of the lower die base and connected to the base plate, and a stamping electric cylinder disposed on the mounting bracket, wherein the telescopic end of the stamping electric cylinder is connected to the stamping head.

[0011] As a further technical solution of this utility model, the side wall of the stamping cylinder is symmetrically provided with limiting grooves, the top plate is provided with a limiting slider that can slide in cooperation with the limiting groove, and a plurality of second springs are provided inside the stamping cylinder, the two ends of the second springs being connected to the lower surface of the top plate and the inner side wall of the bottom of the stamping cylinder, respectively.

[0012] The beneficial effects of this utility model are: The position between the inner sides of the limiting plates on the two sliding seats can limit the two sides of the strip material plate. With the engagement and fixation of the rack and pinion, the position of the sliding seats can be stably locked, effectively avoiding the size deviation of the cover blank caused by the offset of the material plate during stamping, reducing the scrap rate and improving the accuracy of the cover blank. The top plate inside the stamping cylinder cooperates with the second spring to automatically push the cover blank upward out of the stamping cylinder after the stamping is completed, avoiding the cover blank from getting stuck. This not only improves production efficiency, but also reduces the risk of scratches on the surface of the cover blank and hand injuries to workers, thus improving the practicality and safety of the equipment as a whole.

Detailed Implementation

[0018] like Figures 1 to 4 As shown, this utility model provides a technical solution: a metal bottle cap stamping equipment with easy material removal from the lower die, including a base plate 1 and a stamping assembly 3 mounted on the base plate 1. The base plate 1 has limit adjustment members 2 symmetrically arranged on the left and right sides of the stamping assembly 3. The limit adjustment members 2 include a sliding rail 20, a sliding seat 23 symmetrically arranged in the sliding rail 20, a rack 24 arranged in the sliding rail 20 and connected to the base plate 1, a limit fixing member 25 arranged on the sliding seat 23 and capable of engaging with the rack 24 for limit positioning, and a limit upright plate 232 arranged on the top of the sliding seat 23. The stamping assembly 3 includes a lower die base 31 arranged between the sliding rails 20, a stamping cylinder 32 arranged in the lower die base 31, and a stamping head 33 arranged directly above the stamping cylinder 32 and capable of cooperating with the stamping cylinder 32 for stamping. The stamping cylinder 32 has a liftable top plate 321 arranged inside.

[0019] In the limiting adjustment component 2 of this utility model, the sliding seat 23 drives the top limiting plate 232 to move along the sliding rail 20. With the engagement and locking of the rack 24 and the limiting fixing component 25, the limiting distance can be precisely adjusted according to the width of the strip material plate, so as to achieve reliable limiting of the material plate, effectively avoid the material plate deviation caused by manual support, and ensure the dimensional accuracy of the cover blank. The worker only needs to move the material plate in the material feeding direction and move the material plate to the appropriate position before the next stamping, reducing the scrap rate. In the stamping component 3, the stamping electric cylinder 35 on the mounting frame 34 drives the stamping head 33 to move up and down, and precisely cooperates with the stamping cylinder 32 in the lower die base 31 to complete the stamping operation of the cover blank. After stamping, the second spring 324 in the stamping cylinder 32 pushes the top plate 321 to rise automatically, pushing the stuck cover blank out of the cylinder, without the need for manual material removal. The integrated components ensure the stability of the material plate conveying and the accuracy of the stamping positioning, while also realizing the automatic unloading of the cover blank, greatly improving production efficiency. At the same time, it avoids scratches on the cover blank and hand injuries to workers, comprehensively enhancing the practicality and safety of the equipment.

[0020] As one of the preferred embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the sliding rail 20 includes a wall plate 21 symmetrically erected in an inverted L shape on the upper surface of the base plate 1, and a sliding channel 22 formed by the wall plate 21 and the base plate 1. The rack 24 is disposed in the sliding seat 23 and connected to the upper surface of the base plate 1.

[0021] Furthermore, in the above structure, sliding blocks 231 are symmetrically arranged on the left and right sides of the sliding seat 23, the sliding seat 23 is disposed inside the sliding seat 23, and the sliding blocks 231 of the sliding seat 23 cooperate with the sliding rail 20 to slide.

[0022] The wall plate 21 of the sliding rail 20 adopts an inverted L-shaped structure and is symmetrically erected on the upper surface of the base plate 1. Together with the base plate 1, it forms a sliding channel 22 for the sliding seat 23 to move, thereby providing a stable moving guide space for the sliding seat 23. The rack 24 is fixed to the upper surface of the base plate 1 and embedded in the sliding seat 23, providing a meshing basis for subsequent limiting and fixing. The sliding blocks 231 on the left and right sides of the sliding seat 23 are adapted to the inner wall of the sliding channel 22 of the sliding rail 20, which allows the sliding seat 23 to slide smoothly along the sliding channel 22, avoiding deviation or jamming during movement. This ensures that the limiting plate 232 can accurately adjust the spacing with the sliding seat 23, thereby reliably adapting to strip plates of different widths and ensuring the limiting stability during the material conveying process.

[0023] As one of the preferred embodiments of this utility model, such as Figures 1 to 4As shown, the bottom of the sliding seat 23 is provided with a limiting groove 233, the rack 24 is placed in the limiting groove 233, the limiting fixing member 25 is longitudinally disposed inside one end of the sliding seat 23, one end of the limiting fixing member 25 is placed above the sliding seat 23, and the other end of the limiting fixing member 25 is placed in the limiting groove 233 and engages with the rack 24.

[0024] Furthermore, in the above structure, the limiting fixing member 25 includes a lifting rod 252 that is placed outside the limiting upright plate 232 and can be raised and lowered, which is longitudinally inserted inside the sliding seat 23; a limiting pressure plate 251 that is disposed in the limiting through groove 233 of the sliding seat 23 and connected to the lower end of the lifting rod 252; and a first spring 253 that is disposed in the limiting through groove 233 and sleeved outside the lifting rod 252. One end of the first spring 253 is connected to the top side wall of the limiting through groove 233, and the other end of the first spring 253 is connected to the upper surface of the limiting pressure plate 251.

[0025] Furthermore, the upper surface of the rack 24 is provided with a first biting tooth, and the lower surface of the limiting pressure plate 251 is provided with a second biting tooth that can engage with the first biting tooth.

[0026] The limiting groove 233 at the bottom of the sliding seat 23 provides a precise accommodating space for the rack 24, allowing the rack 24 to be stably embedded inside the sliding seat 23. This ensures the tightness of the fit between the two and also provides a reasonable stroke for the meshing action of the limiting fastener 25 and the rack 24.

[0027] The limiting fastener 25 extends longitudinally through the sliding seat 23, with one end exposed above the sliding seat 23 for easy manual operation, and the other end placed in the limiting through groove 233 to achieve a locking function. The lifting rod 252 in the limiting fastener 25 extends longitudinally through the interior of the sliding seat 23 and is located outside the limiting plate 232. Workers can easily control the locking state by lifting the lifting rod 252. The limiting pressure plate 251 connected to the lower end of the lifting rod 252 cooperates with the rack 24. The first spring 253, which is sleeved on the outside of the lifting rod 252, provides continuous downward pressure to the limiting pressure plate 251 under normal conditions through its connection with the top side wall of the limiting through groove 233 and the upper surface of the limiting pressure plate 251, respectively, ensuring that it stably engages with the rack 24.

[0028] The first engagement tooth on the upper surface of the rack 24 is matched with the second engagement tooth on the lower surface of the limiting pressure plate 251. The toothed engagement design can greatly improve the locking firmness and effectively prevent the sliding seat 23 from being displaced due to vibration during the stamping process.

[0029] As one of the preferred embodiments of this utility model, such as Figure 1As shown, the stamping assembly 3 also includes a mounting bracket 34 disposed on the rear side of the lower die base 31 and connected to the base plate 1, and a stamping electric cylinder 35 disposed on the mounting bracket 34. The telescopic end of the stamping electric cylinder 35 is connected to the stamping head 33.

[0030] Mounting bracket 34 is fixedly connected to base plate 1 and located behind lower die base 31, providing a stable mounting base for stamping electric cylinder 35. Stamping electric cylinder 35 and stamping cylinder 32 inside lower die base 31 are vertically aligned to avoid positional deviation during stamping. The telescopic end of stamping electric cylinder 35 is directly connected to stamping head 33. The telescopic movement of the electric cylinder drives the stamping head 33 to move up and down, realizing the stamping operation of strip material. As one of the preferred embodiments of this utility model, such as Figure 4 As shown, the side wall of the stamping cylinder 32 is symmetrically provided with limiting grooves 323. The top plate 321 is provided with a limiting slider 322 that can slide in cooperation with the limiting groove 323. The stamping cylinder 32 is provided with a plurality of second springs 324. The two ends of the second springs 324 are respectively connected to the lower surface of the top plate 321 and the inner side wall of the bottom of the stamping cylinder 32.

[0031] The symmetrical limiting grooves 323 on the side wall of the stamping cylinder 32 are adapted to the limiting sliders 322 on the top plate 321, providing stable guidance for the lifting and lowering movement of the top plate 321, preventing it from deviating during vertical movement, and ensuring the accuracy of the ejection action. Several second springs 324 inside the stamping cylinder 32 are connected at both ends to the lower surface of the top plate 321 and the inner side wall of the bottom of the stamping cylinder 32, respectively. Under normal conditions, they can support the top plate 321 at a suitable height. During stamping, the top plate 321 is compressed by the pressure of the stamping head 33, causing the second springs 324 to sink. After stamping is completed, the second springs 324 quickly return to their original position, pushing the top plate 321 to rise smoothly along the limiting grooves 323, automatically ejecting the cover blank stuck in the stamping cylinder 32. This not only improves production efficiency but also avoids the risk of cover blank scratches and worker hand injuries, ensuring the continuity and safety of the stamping operation.

[0032] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
