Description

Technical Field

[0001] This utility model relates to the field of gasket stamping equipment, and in particular to a gasket stamping forming device. Background Technology

[0002] In numerous fields such as machinery manufacturing, electronics, and the automotive industry, gaskets are a fundamental sealing, shock-absorbing, or insulating component with a huge demand. Currently, the production of small- to medium-scale or small-batch gaskets generally adopts stamping processes. Traditional gasket stamping equipment has a simple structure and relies on manual feeding, positioning, and unloading. Operators need to manually place strips or sheets of metal or non-metal materials onto the mold, start the stamping equipment to complete one stamping cycle, and then manually move the material to the next workstation, or separate and collect the stamped gaskets from the scrap.

[0003] Because each stamping cycle requires manual intervention for feeding and positioning, the stamping pace is slow and continuous production is impossible, severely limiting capacity expansion. Secondly, the stamping quality of the products is difficult to guarantee consistently. Manual feeding inevitably introduces positioning errors, easily leading to burrs, dimensional errors, and even misalignment or scrapping due to improper material placement, making it difficult to control the product yield. Furthermore, there are safety concerns. Manually operating near a high-speed reciprocating stamping head requires extremely high levels of skill and attention from the operator, posing a risk of mechanical injury. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0017] Please see Figure 1-3 This utility model provides a technical solution: a gasket stamping and forming device, including a guide plate 1, a base 2, a support plate 3, a hydraulic device 4, a pressure plate 5, a first pressure block 6, a second pressure block 7, and a pushing structure 8. The guide plate 1 is fixed on the base 2, and the support plate 3 is fixed on both sides of the base 2. Hydraulic device 4, installed on support plate 3, is used to drive pressure plate 5 to move up and down; The pressure plate 5 is installed on the hydraulic device 4. The first pressure block 6 and the second pressure block 7 are respectively fixed below the pressure plate 5. The first pressure block 6 and the second pressure block 7 are arranged in order from small to large along the direction of material movement. The push structure 8, installed inside the base 2, is used to push the material along the guide plate 1.

[0018] In this invention, the pushing structure 8 includes a connecting rod 81, a trapezoidal block 82, a driving sprocket 83, a driven sprocket 84, a chain 85, push blocks 86, and elongated blocks 87. One end of the connecting rod 81 is fixed to the pressure plate 5, and the other end is slidably inserted into the guide plate 1. The trapezoidal block 82 is fixed to the end of the connecting rod 81 near the base 2. The driving sprocket 83 and the driven sprocket 84 are rotatably mounted in the base 2. One side of the chain 85 meshes with the driving sprocket 83, and the other side meshes with the driven sprocket 84. Multiple push blocks 86 are equidistantly distributed on the chain 85, and multiple elongated blocks 87 are equidistantly distributed on the driving sprocket 83. When the pushing structure 8 is running, the connecting rod 81 is driven by the pressure plate 5 to move up and down reciprocally. The up and down movement of the connecting rod 81 causes the trapezoidal block 82 to move up and down along with the connecting rod 81. The guide block 9 located on the connecting rod 81 makes the up and down reciprocating movement of the connecting rod 81 more stable. During the reciprocating movement of the two trapezoidal blocks 82, when the two trapezoidal blocks 82 move upwards, the lower trapezoidal block 82 pushes the elongated block 87 one position to the right via the inclined plane. The distance of one position is the distance between the two adjacent elongated blocks 87. When the two trapezoidal blocks 82 move downwards, the upper trapezoidal block 82 pushes the other elongated block 87 forward again via the inclined plane. This process repeats, causing the elongated block 87 to rotate intermittently around the drive sprocket 83 at a certain speed. When the drive sprocket 83 rotates, it drives the driven sprocket 84 to rotate via the chain 85. When the chain 85 moves, it drives the pusher block 86 to move, which in turn pushes the material along the guide plate 1. One cycle of the trapezoidal blocks 82 can move the pusher block 86 the distance between the first pressing block 6 and the second pressing block 7. At the same time, the pusher block 86 pushes the material to move the distance between the first pressing block 6 and the second pressing block 7.

[0019] In this invention, a guide block 9 is provided on the connecting rod 81. The guide block 9 is fixed on the connecting rod 81 and slidably connected to the guide plate 1. The guide block 9 on the connecting rod 81 makes the up-and-down reciprocating movement of the connecting rod 81 more stable.

[0020] In this invention, a storage box 10 is provided on the base 2, which is slidably installed inside the base 2 and located below the second pressing block 7. A waste collection box 11 is also provided on the base 2, which is slidably installed inside the base 2 and located below the first pressing block 6. The waste collection box 11, located below the first pressing block 6, can collect waste material that is pressed off the material, while the storage box 10, located below the second pressing block 7, can collect molded pads that are pressed off the material. The waste collection box 11 and the storage box 10 facilitate workers to better classify and collect waste and finished products.

[0021] In this utility model, the guide plate 1 is provided with an anti-detachment plate 12, which is fixed on both sides of the guide plate 1. The anti-detachment plate 12 on the guide plate 1 is located on the right side of the guide plate 1, which can prevent the material from detaching when it enters the processing area. The left side of the guide plate 1 is not provided with an anti-detachment plate 12, which makes it convenient for workers to place the material on the guide plate 1.

[0022] In this invention, a positioning rod 13 is provided on the pressure plate 5, and the positioning rod 13 is fixed on the pressure plate 5. By means of the positioning rod 13 located on the pressure plate 5, the material can be fixed when the first pressure block 6 and the second pressure block 7 press the material, thereby improving the forming accuracy of the finished gasket.

[0023] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires, and should select appropriate controllers according to actual conditions to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical connections between the various electrical components are completed in sequence. The detailed connection methods are well-known technologies in the field. The following mainly introduces the working principle and process, and will not describe the electrical control further.

[0024] In this implementation scheme: the material travels from left to right. When stamping the gasket, the worker places the material to be stamped on the left side of the center of the guide plate 1 above the base 2. At this time, the hydraulic device 4 is activated, and the hydraulic device 4 located on the support plate 3 drives the pressure plate 5 to move up and down. The anti-detachment plate 12 on the guide plate 1 is located on the right side of the guide plate 1, which can prevent the material from detaching when it enters the processing area. The left side of the guide plate 1 does not have an anti-detachment plate 12, which makes it easier for the worker to place the material on the guide plate 1. When the pressure plate 5 moves up and down, the pressure plate 5 will drive the first pressure block 6, the second pressure block 7 and the pushing structures 8 on both sides to move.

[0025] When the push structure 8 is running, the connecting rod 81 is driven by the pressure plate 5 to move up and down reciprocally. The up and down movement of the connecting rod 81 causes the trapezoidal block 82 to move up and down along with the connecting rod 81. The guide block 9 located on the connecting rod 81 makes the up and down reciprocating movement of the connecting rod 81 more stable. During the up and down reciprocating movement of the two trapezoidal blocks 82, when the two trapezoidal blocks 82 move upward, the lower trapezoidal block 82 will push the elongated block 87 to the right by a certain distance through the inclined plane. The distance of one direction is the distance between the two adjacent elongated blocks 87. When the two trapezoidal blocks 82 move downward, the upper trapezoidal block 82 will push the other elongated block 87 forward by a certain distance through the inclined plane. In this way, the elongated block 87 will rotate intermittently around the driving sprocket 83 at a certain speed. When the driving sprocket 83 rotates, it will drive the driven sprocket 84 to rotate through the chain 85. When the chain 85 moves, it drives the pusher block 86 to move, which in turn pushes the material along the guide plate 1. One cycle of the trapezoidal block 82 moves the pusher block 86 a distance from the first pressing block 6 to the second pressing block 7. Simultaneously, the pusher block 86 pushes the material a distance from the first pressing block 6 to the second pressing block 7.

[0026] While the structure 8 is running, the pressure plate 5 moves up and down, causing the first pressure block 6 and the second pressure block 7 to move up and down as well. The positioning rod 13 on the pressure plate 5 can fix the material during the pressing process by the first pressure block 6 and the second pressure block 7, improving the forming accuracy of the finished gasket. The first pressure block 6 and the second pressure block 7 are arranged in ascending order along the material's direction of travel. When the material reaches the first pressure block 6, it is squeezed, pressing a small circle with the same diameter as the first pressure block 6 onto the material. When the material reaches the second pressure block 7, it presses a large circle with the same diameter as the second pressure block 7 downwards from the position of the small circle. At this point, a complete gasket can be pressed off the material. Repeating the above operation automatically presses the material, eliminating the need for manual material handling. The waste collection box 11 located below the first pressing block 6 can collect the waste material that is pressed off from the material, and the storage box 10 located below the second pressing block 7 can collect the molded pads that are pressed off from the material. The waste collection box 11 and the storage box 10 make it easier for staff to classify and collect waste and finished products.
