Abstract
Description
Technical Field
[0001] Embodiments of the present disclosure relate to the technical field of rubber gasket processing equipment. Specifically, it relates to a punching device for rubber gasket processing. Background Art
[0002] In the field of rubber gasket production and manufacturing, circular rubber gaskets are widely used in multiple industries such as machinery and automobiles due to their good sealing and shock-absorbing properties. However, traditional punching equipment for circular rubber gaskets has significant defects in processing efficiency and process design, making it difficult to meet the increasing production demands.
[0003] Currently, most punching equipment for circular rubber gaskets adopts the method of feeding one by one with single sheets. Operators need to accurately lay the rubber sheets at the designated positions on the equipment and then perform punching operations. This feeding method not only requires extremely high proficiency of operators, but also can only process one sheet at a time, severely limiting the production efficiency. At the same time, accurately laying the rubber sheets is time-consuming and laborious, and during repeated operations, it is extremely easy for the positions of the rubber sheets to shift, resulting in a decrease in punching accuracy and an increase in the rejection rate. In addition, existing equipment generally follows the processing flow of forming first and then punching. Once problems occur in the punching process of the formed rubber gasket, the entire gasket is scrapped, causing a great waste of raw materials.
[0004] With the continuous growth of the market demand for rubber gaskets, the traditional processing mode of feeding single sheets one by one and forming first and then punching has become a bottleneck restricting production efficiency and cost control. Therefore, it is of great significance to develop a punching device for rubber gasket processing that can break through the traditional processing flow, achieve punching first and then forming, and has an efficient feeding function, so as to improve production efficiency and reduce production costs. Utility Model Content
[0005] To overcome the above defects, embodiments of the present disclosure provide a punching device for rubber gasket processing, which solves the technical problem in the prior art that most punching equipment for circular rubber gaskets adopts the method of feeding one by one with single sheets. Operators need to accurately lay the rubber sheets at the designated positions on the equipment and then perform punching operations. This feeding method not only requires extremely high proficiency of operators, but also can only process one sheet at a time, severely limiting the production efficiency.
[0006] According to one aspect, at least one embodiment of the present disclosure provides a punching device for rubber gasket processing, including:
[0007] A conveying frame and a supporting chassis, the supporting chassis is fixed at the bottom of the conveying frame;
[0008] A guiding and winding component, the guiding and winding component is arranged on the conveying frame;
[0009] A pair of fixed rods and a punching assembly, wherein the fixed rods are fixed to the upper end of the conveyor frame, and the punching assembly is disposed on the fixed rods and the conveyor frame;
[0010] The punching assembly includes a pair of movable rods, each of which is movably fitted to both ends of the top of the conveyor frame. A crossbar is provided at the upper end of the movable rod, and several punching rods are provided at the bottom of the crossbar. Several shaped circular holes are opened on the surface of the conveyor frame, and the shaped circular holes correspond to the positions of the punching rods.
[0011] As a further technical solution, each of the movable rods is fitted with a buffer spring, and a mounting bracket is connected to one side of each pair of fixed rods. An eccentric shaft is rotatably connected to the mounting bracket via electric drive. A transmission rod is movably fitted to one end of the eccentric shaft, and the lower end of the transmission rod is rotatably connected to the surface of the crossbeam via a pin.
[0012] As a further technical solution, the guiding and winding assembly includes a conveying roller, which is rotatably connected inside the conveying frame. The conveying roller is driven to rotate by electricity, and a drive shaft sleeve is provided on one side of the conveying frame.
[0013] As a further technical solution, a winding rod is inserted and connected inside the drive shaft sleeve, and a splicing plate is fixedly connected to the other side surface of the conveyor frame by bolts. The splicing plate is rotatably fitted and connected to one end of the winding rod.

[0018] The beneficial effects of the embodiments disclosed herein are as follows:
[0019] In this disclosure, the punch assembly achieves continuous and efficient punching of rubber materials through eccentric transmission and buffer design. The eccentric shaft on the mounting frame is electrically driven to rotate, and the rotational motion is converted into the up-and-down reciprocating motion of the crossbeam through the transmission rod. This allows several punching rods at the bottom of the crossbeam to quickly pass through the formed circular holes on the surface of the conveyor frame, continuously punching the rubber material. The buffer springs fitted on the movable rods compress and buffer when the punching rods are pressed down, and extend and reset when they move up, avoiding rigid collisions between the punching rods and the conveyor frame. This ensures the stability of the equipment operation and extends the service life of the components.
[0020] This component revolutionizes the traditional single-piece feeding processing mode, enabling simultaneous punching of multiple locations on the rubber material. This significantly improves punching efficiency and solves the problem of traditional equipment processing only one piece at a time, resulting in low production efficiency. Simultaneously, the stable transmission of the eccentric shaft ensures the accuracy of the punching position, reducing the scrap rate caused by manual laying deviations, and allowing high-precision punching operations to be completed during continuous conveying of the rubber material.

It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0033] like Figures 1-4 The diagram illustrates a punching apparatus for processing rubber gaskets according to an embodiment of the present disclosure, comprising:
[0034] The conveyor frame 1 and the supporting base frame 2 are fixed to the bottom of the conveyor frame 1.
[0035] Guided winding assembly 5, which is disposed on the conveyor frame 1;
[0036] A pair of fixing rods 3 and a punching assembly 4, wherein the fixing rods 3 are fixed to the upper end of the conveyor frame 1, and the punching assembly 4 is disposed on the fixing rods 3 and the conveyor frame 1;
[0037] The punching assembly 4 includes a pair of movable rods 4-1, each of which is movably fitted onto the top ends of the conveyor frame 1. A crossbeam 4-2 is provided at the upper end of each movable rod 4-1, and several punching rods 4-3 are provided at the bottom of the crossbeam 4-2. Several forming round holes 4-4 are opened on the surface of the conveyor frame 1, and the forming round holes 4-4 correspond to the positions of the punching rods 4-3. A buffer spring 4-5 is fitted onto each movable rod 4-1. A mounting bracket 4-6 is connected to one side of the pair of fixed rods 3. An eccentric shaft bracket 4-7 is rotatably connected to the mounting bracket 4-6 by electric drive. A transmission rod 4-8 is movably fitted onto one end of the eccentric shaft bracket 4-7, and the lower end of the transmission rod 4-8 is rotatably connected to the surface of the crossbeam 4-2 by a pin.
[0038] In some examples, a punching assembly 4 is designed to achieve continuous and rapid punching of rubber materials. An electrically driven eccentric shaft 4-7 on the mounting bracket 4-6 generates eccentric motion through rotation, driving a transmission rod 4-8 to reciprocate. The lower end of the transmission rod 4-8 is rotatably connected to the crossbeam 4-2 via a pin, converting the rotational motion of the eccentric shaft 4-7 into the up-and-down reciprocating motion of the crossbeam 4-2. When the crossbeam 4-2 moves downward, the buffer spring 4-5 is compressed, and several punching rods 4-3 quickly pass through the formed circular holes 4-4 on the surface of the conveyor frame 1, punching the rubber material below. When the crossbeam 4-2 moves upward and resets, the buffer spring 4-5 extends to provide cushioning force, preventing the punching rods 4-3 from rigidly colliding with the conveyor frame 1.
[0039] This eccentric transmission structure, combined with the buffer spring 4-5, enables the punching rod 4-3 to punch continuously and quickly at a stable frequency. Compared with the traditional single-piece processing method, this greatly improves the punching efficiency and ensures that multiple holes can be quickly formed on the rubber material.
[0040] like Figures 1-4As shown, this embodiment proposes that the guide winding assembly 5 includes a conveying roller 5-1, which is rotatably connected to the conveying frame 1. The conveying roller 5-1 is driven to rotate by electricity. A drive shaft sleeve 5-2 is provided on one side of the conveying frame 1, and a winding rod 5-3 is inserted and connected inside the drive shaft sleeve 5-2. A splicing plate 5-4 is fixedly connected to the other side surface of the conveying frame 1 by bolts. The splicing plate 5-4 is rotatably fitted onto one end of the winding rod 5-3.
[0041] In some examples, a guide winding assembly 5 is designed to meet subsequent molding requirements. An electrically driven conveyor roller 5-1 rotates at a constant speed, smoothly conveying the rubber material laid on the conveyor frame 1, providing a continuous supply of raw materials for the punching operation. After the rubber material is punched, the conveyor roller 5-1 continues to convey it, guiding it to the winding rod 5-3. The insert connection design between the drive bushing 5-2 and the winding rod 5-3 allows for flexible disassembly and replacement of the winding rod 5-3, meeting the winding requirements of rubber materials of different sizes. A splicing plate 5-4 is rotatably fitted onto one end of the winding rod 5-3, providing auxiliary support and guidance to ensure that the rubber material is evenly wound onto the winding rod 5-3.
[0042] After being wound up, the rubber material roll can be directly transferred to the pressure equipment. Through the subsequent stamping and forming process, the rubber material with holes is processed into a ring-shaped rubber gasket, realizing an efficient production process of punching holes first and then forming.
[0043] like Figures 1-4 As shown, this embodiment also includes a collection component 6, which includes a centralized hopper 6-1. The centralized hopper 6-1 is fixed to the bottom of the conveyor frame 1 and is located below the forming circular hole 4-4. A pair of positioning slide rails 6-2 are provided on the inner surface of the support base frame 2. A collection box 6-3 is placed in the positioning slide rails 6-2 and is located below the centralized hopper 6-1.
[0044] In some examples, a collection assembly 6 is designed to centrally collect punching waste. A centralized hopper 6-1 is fixed to the bottom of the conveyor frame 1 and directly opposite the forming hole 4-4. When the punching rod 4-3 passes through the forming hole 4-4 for punching, the generated rubber waste falls directly into the centralized hopper 6-1. A positioning slide rail 6-2 on the inner surface of the supporting base 2 provides precise guidance and stable support for the collection box 6-3. Operators can easily push or pull the collection box 6-3 in and out along the positioning slide rail 6-2. When the collection box 6-3 is full of waste, it can be easily removed for cleaning, preventing waste from scattering and polluting the working environment, while ensuring the continuity of punching operations. The entire waste collection process is highly automated, effectively improving on-site management and production efficiency in rubber gasket processing.
[0045] For example, such as Figure 2As shown, a stabilizing roller 7 is rotatably connected inside the conveyor frame 1.
[0046] In some examples, by setting a stabilizing roller 7, it can press on the surface of the punched rubber material and cooperate with the winding to avoid affecting the punching process. At the same time, it can also ensure that the rubber material is pressed flat on the surface of the conveyor frame 1, and move stably and without deviation during the punching process, which has a good auxiliary effect.
[0047] For example, such as Figure 4 As shown, a locking block 8 is provided inside the drive shaft sleeve 5-2, and the locking block 8 is inserted into one end of the winding rod 5-3.
[0048] In some examples, by setting a locking block 8, the winding rod 5-3 can be limited and fixed, so that the winding rod 5-3 can stably follow the rotation of the drive shaft sleeve 5-2, avoiding slippage caused by the weight of the winding rod 5-3 due to the increase of material, and also ensuring the tension during winding to prevent loosening after winding.
[0049] In actual use: the rubber material is laid on the surface of the conveyor frame 1 and conveyed downward by the conveyor roller 5-1. The rubber is flattened with the help of the stabilizing roller 7. One end is pulled out and wound onto the take-up rod 5-3. Then the conveying and take-up are started. During the process, the eccentric shaft frame 4-7 is started to drive the transmission rod 4-8, which makes the multiple punching rods at the bottom of the cross frame 4-2 punch holes quickly. The rubber sheets that fall off the punching holes slide into the collection box 6-3 through the collection hopper 6-1. After the take-up rod 5-3 is rotated and fully wound, the bolts are removed and the splicing plate 5-4 is taken off. Then the take-up rod 5-3 and the rubber material are taken off and transferred to the molding equipment for final molding.
[0050] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure 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 solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
