Description

Technical Field

[0001] This utility model relates to the field of automotive sound-absorbing cotton processing technology, and in particular to a stamping equipment for producing automotive sound-absorbing cotton. Background Technology

[0002] Automotive sound-absorbing cotton stamping is a process that uses stamping equipment and molds to stamp and shape sound-absorbing cotton materials. Rolls or sheets of sound-absorbing cotton are placed in the mold, and the pressure of the stamping machine causes the sound-absorbing cotton to be cut and shaped according to the shape and size of the mold.

[0003] For example, CN210879997U discloses a stamping equipment for producing automotive sound-absorbing cotton. The stamping equipment for producing automotive sound-absorbing cotton includes a frame and a stamping mechanism. A worktable is fixedly provided on the frame. The stamping mechanism includes a mold fixed on the worktable and a cylinder located on the top of the frame. A tool holder is fixedly connected to the top of the telescopic rod of the cylinder. Several punches are provided on the tool holder. Several stamping holes are opened on the mold, and the positions of the stamping holes correspond one-to-one with the positions of the punches.

[0004] However, in existing technologies, if misalignment occurs during the stamping process of automotive sound-absorbing cotton, it is necessary not only to adjust the stamping process and inspect and repair the mold, but also to re-stamp some products. This not only leads to a longer production cycle and reduced production efficiency, but also easily causes parts to have uneven edges, localized material shortages or excesses. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the prior art that if a misalignment occurs, the parts are prone to uneven edges, partial material shortages or excess material, and to propose a stamping equipment for producing automotive sound-absorbing cotton.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a stamping device for producing automotive sound-absorbing cotton, comprising a support base and cylinders fixedly installed on both sides of its top, a limiting mechanism installed at the center of the top of the support base, and a stamping mechanism installed above the limiting mechanism;

[0007] The stamping mechanism includes a mounting plate and a base. Limiting rods are fixedly connected to both sides of the bottom of the mounting plate. The bottom of the base is fixedly connected to the top of the support base. Sliding blocks are slidably connected to both sides of the top of the base. Limiting holes are opened on the surface of the sliding blocks. The limiting rods are slidably connected to the limiting holes, and the bottom end of the limiting rods passes through the limiting holes. A hydraulic cylinder is installed in the center of the top of the mounting plate. A stamping block is fixedly connected to the bottom end of the hydraulic cylinder.

[0008] Preferably, lifting plates are fixedly connected to both sides of the mounting plate, and the lifting plates are fixedly connected to the cylinder output end.

[0009] Preferably, each of the two sliding blocks is fixedly connected to a pressing block on one side facing each other.

[0010] Preferably, the limiting mechanism includes a limiting frame, the bottom end of which is fixedly connected to the base, and both sides of the limiting frame are slidably connected to a pressing rod.

[0011] Preferably, a limiting plate is fixedly connected to the top of the extrusion rod, and a spring is sleeved on the outer surface of the extrusion rod.

[0012] Preferably, a threaded rod is threadedly connected to the middle of the base, and a lower mold is rotatably connected to the top of the threaded rod.

[0013] Preferably, slide rods are fixedly connected to both sides of the bottom of the lower mold, and the bottom ends of the slide rods pass through the base and the support.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] 1. In this utility model, by coordinating the control of components such as cylinders, lifting plates, limit rods, sliding blocks, and hydraulic cylinders, efficient and precise stamping of sound-absorbing cotton is achieved. The material edges are fixed in advance by the limit rods driving the sliding blocks and extrusion blocks, which effectively avoids the problems of offset, wrinkles and deformation during the stamping process, significantly improving the positioning accuracy and product consistency. At the same time, the stamping blocks move stably vertically under the constraint of the limit frame, ensuring uniform distribution of stamping pressure and improving the forming quality. The overall structure moves smoothly and fits tightly, improving the stability of operation and the safety of equipment.

[0016] 2. In this utility model, the material is pre-pressed by a spring-driven extrusion rod, which effectively fixes the material position and enhances its fit stability with the mold. This avoids material displacement, warping, or forming errors during the stamping process, improving the processing accuracy and consistency of the product. At the same time, the height of the lower mold is adjusted by a threaded rod, achieving precise control of the mold in the vertical direction. Combined with the guiding and limiting function of the slide rod, it ensures that the mold runs smoothly during the lifting process, avoiding mold wear or workpiece damage caused by deviation. The overall structural design is reasonable, ensuring the stability, safety, and product yield of the stamping operation. Attached Figure Description

Detailed Implementation

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] 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. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1: As Figures 1-4 As shown, this utility model provides a stamping equipment for producing automotive sound-absorbing cotton, including a support base 1 and cylinders 2 fixedly installed on both sides of its top. A limiting mechanism 5 is installed at the center of the top of the support base 1, and a stamping mechanism 4 is installed above the limiting mechanism 5.

[0025] The stamping mechanism 4 includes a mounting plate 42 and a base 46. Limiting rods 41 are fixedly connected to both sides of the bottom of the mounting plate 42. The bottom of the base 46 is fixedly connected to the top of the support base 1. Sliding blocks 45 are slidably connected to both sides of the top of the base 46. Limiting holes 47 are opened on the surface of the sliding blocks 45. The limiting rods 41 are slidably connected to the limiting holes 47, and the bottom end of the limiting rods 41 passes through the limiting holes 47. A hydraulic cylinder 43 is installed in the center of the top of the mounting plate 42. A stamping block 44 is fixedly connected to the bottom end of the hydraulic cylinder 43.

[0026] Lifting plates 3 are fixedly connected to both sides of the mounting plate 42, and the lifting plates 3 are fixedly connected to the output end of the cylinder 2. Pressing blocks 48 are fixedly connected to the two sliding blocks 45 on opposite sides.

[0027] The specific settings and functions of this embodiment are described below. When stamping the sound-absorbing cotton, the raw material is first neatly placed at the designated position on the lower mold 53 to ensure that the material is completely in contact with the mold surface, so as to avoid displacement or wrinkles in subsequent operations. Then, the control system activates the cylinder 2, pushing the lifting plate 3 to move downward in the vertical direction. At this time, the mounting plate 42 installed at the bottom of the lifting plate 3 will also descend synchronously, thereby driving the limiting rod 41 installed on it to move downward together. During the descent, the limiting rod 41 will slide precisely inside the limiting hole 47, thereby guiding and constraining the movement path of the sliding mechanism.

[0028] Simultaneously, the limiting rod 41 applies a certain pushing force to the sliding block 45, causing the sliding block 45 to begin moving horizontally. Due to the guiding fit between the sliding block 45 and the base 46, its movement is effectively restricted by the structure of the base 46, ensuring a smooth and consistent sliding process. During its movement, the sliding block 45 further pushes the connected extrusion block 48 closer to the raw material, allowing the extrusion block 48 to pre-fix and press the edge of the raw material, effectively preventing the sound-absorbing cotton from shifting, deflecting, or deforming due to uneven force during subsequent stamping stages, thereby improving stamping accuracy and product consistency.

[0029] After the material is pre-positioned, the hydraulic cylinder 43 starts working, driving the stamping block 44 to move downwards at high speed in the vertical direction. During the movement, the stamping block 44 is constrained by the middle structure of the limiting frame 51, ensuring that it presses precisely against the lower die 53 along a predetermined trajectory, thereby quickly and evenly stamping the sound-absorbing cotton. This limiting structure not only prevents the stamping block 44 from shifting due to lateral forces, but also improves the stability and safety of the entire machine. After stamping is completed, the hydraulic cylinder 43 reverses and drives the stamping block 44 back to its original position. Subsequently, the lifting plate 3 is lifted by the cylinder 2, releasing the constraint on the sliding block 45 and the extrusion block 48.

[0030] Example 2: Figure 2 and Figure 4 As shown, the limiting mechanism 5 includes a limiting frame 51, the bottom end of which is fixedly connected to the base 46, and both sides of the limiting frame 51 are slidably connected to pressing rods 56. A limiting plate 52 is fixedly connected to the top of the pressing rod 56, and a spring 57 is sleeved on the outer surface of the pressing rod 56. A threaded rod 54 is threadedly connected to the middle of the base 46, and a lower mold 53 is rotatably connected to the top of the threaded rod 54. Sliding rods 55 are fixedly connected to both sides of the bottom of the lower mold 53, and the bottom ends of the sliding rods 55 penetrate the base 46 and the support base 1.

[0031] The overall effect of this embodiment is that, during the stamping operation, the material to be processed is first accurately placed on top of the lower die 53. At this time, under the elastic action of the spring 57, the extrusion rod 56 connected to it is subjected to a downward thrust, thereby applying a certain pre-compression to the upper surface of the material. This pre-compression not only effectively fixes the material position but also improves the material's bonding stability, thereby further avoiding problems such as stamping skewing and offset caused by material displacement or warping during the stamping process. The setting of this elastic pre-compression mechanism helps to improve the accuracy of product processing and the yield rate.

[0032] Furthermore, to achieve precise vertical lifting and lowering of the lower mold 53, a threaded rod 54 is incorporated into the system design as an adjustment component. During operation, rotating the threaded rod 54 allows the lower mold 53 to move precisely vertically, thus enabling fine-tuning and control of the mold's position. During mold lifting and lowering, the slide rod 55 serves as a guide and limiter; its structural design ensures that the lower mold 53 remains vertical during movement, preventing damage to the mold or workpiece due to misalignment.

[0033] The operating method and working principle of this device are as follows: When stamping the sound-absorbing cotton, the raw material is first placed on the top of the lower mold 53. Then, the cylinder 2 drives the lifting plate 3 to move downwards, causing the limiting rod 41 at the bottom of the mounting plate 42 to move downwards synchronously. During the sliding process of the limiting rod 41 within the limiting hole 47, it applies a force to the sliding block 45, causing it to begin moving along the guide direction. The sliding block 45 is constrained by the base 46 during its movement, thereby causing the extrusion block 48 to gradually approach the material, initially pressing and positioning it to prevent displacement during the stamping process.

[0034] Immediately afterwards, the hydraulic cylinder 43 is activated, driving the stamping block 44 to move downward in the vertical direction, and completing the stamping and forming operation of the raw material under the guidance of the middle structure of the limit frame 51.

[0035] During the stamping process, after the material is placed on top of the lower die 53, the spring 57 provides a downward elastic force, pushing the extrusion rod 56 downward to apply stable pressure to the top of the material, thereby further preventing the material from tilting during stamping.

[0036] Furthermore, the position of the lower die 53 can be precisely adjusted by rotating the threaded rod 54. During the lifting and lowering process, the die is first guided and restricted by the slide rod 55, effectively preventing tilting during movement and ensuring the accuracy and stability of the stamping process.

[0037] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art can easily use the above-disclosed technical content to make changes or modifications to equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
