Description

Technical Field

[0001] This utility model relates to the technical field of engine cylinder head gasket processing equipment, specifically to a stamping device for processing engine cylinder head gaskets with a material ejection mechanism. Background Technology

[0002] The stamping and forming equipment is closely related to engine cylinder head gaskets, serving as a key component in their production. The cylinder head gasket is a sealing component of the engine, located between the cylinder head and cylinder block, preventing gas leakage and separating coolant and lubricating oil. The stamping and forming equipment uses forming technology to shape the metal into the required form, ensuring the cylinder head gasket's elasticity and sealing performance. The precision of the equipment determines the size and function of the cylinder head gasket, especially its complex hole and sealing rib design. Furthermore, the efficient production of the stamping and forming equipment meets the large-scale demands of the automotive industry, reducing costs. The automated and quality inspection systems equipped in the equipment ensure product consistency and quality, guaranteeing engine reliability and durability.

[0003] According to CN117732984B, the continuous engine cylinder head gasket stamping preparation device includes a processing table. A clamping mechanism is provided on the upper surface of the processing table and in the middle. A moving mechanism is provided on the inner side of the two fixed frames. The moving mechanism includes a moving seat. A sliding groove and a moving groove are respectively opened inside the moving seat. A synchronous stamping mechanism is provided on the inner side of the sliding groove.

[0004] The above-mentioned technology utilizes a clamping mechanism and a moving mechanism to effectively punch holes evenly or unevenly on the upper surface of the cylinder head gasket. However, many pressurizing devices cannot guarantee that damaged objects will be removed during use. If damaged objects are not removed in time after being pressurized, it will cause disorder in the overall equipment.

[0005] Therefore, in view of this, we have studied and improved the existing shortcomings and proposed a stamping device for engine cylinder head gasket processing with a material ejection mechanism. Utility Model Content

[0006] The purpose of this invention is to provide an engine cylinder head gasket processing stamping device with a material ejection mechanism to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an engine cylinder head gasket processing stamping device with a material ejection mechanism, comprising: a power box, a support at the bottom of the power box, a vertical frame on one side of the bottom of the support, a rectangular channel horizontally opened at the lower end of the surface of the vertical frame, a pressure cylinder at the middle of the bottom of the support, an extension frame at the bottom of the vertical frame, a first platform at the top of the front end of the extension frame, a rail groove at the middle of the top of the first platform, a spring at the front end of the inner side of the rail groove, a slider at one end of the spring, a pressure plate at the top of the slider, and a workpiece body at the top of the pressure plate;

[0008] An electric telescopic rod is provided on the back of the extension frame, rails are provided on both sides of the front end of the extension frame, a push shaft is provided on the outer side of the rails, a rotating block is provided on the inner side of the push shaft, a contact plate is provided on one side of the rotating block, a curved piece is provided at the front end of the contact plate, an iron block is provided at the front end of the curved piece, a grafting rod is provided on the lower side of the front end of the curved piece, and an auxiliary structure is provided on the outer side of the pressure plate.

[0009] Furthermore, the slider and the spring form a sliding connection, and the rail groove and the slider form an elastic connection, which facilitates the slider and the spring to provide cushioning for the slider.

[0010] Furthermore, the front part of the iron block is covered with a magnetic surface, and the curved plate is S-shaped to facilitate the curved plate to provide different heights for the iron block.

[0011] Furthermore, the rectangular channel from the tail end of the extension frame to the lower end of the vertical frame surface is provided with a sliding structure consisting of three touch plates, rotating blocks, push shafts, iron blocks, and grafting rods. The sliding structure consisting of touch plates, rotating blocks, push shafts, iron blocks, and grafting rods arranged between the tail end of the extension frame and the lower end of the vertical frame surface is arranged in a stepped shape. Moreover, the length of the grafting rods in the sliding structure consisting of the three touch plates, rotating blocks, push shafts, iron blocks, and grafting rods is arranged from bottom to top, with the length decreasing from long to short, so that the iron blocks and grafting rods can attract the magnetic cards.

[0012] Furthermore, the auxiliary structure includes a magnetic card, a magnetic plate, a positioning rod, and a built-in structure. A magnetic card is attached to the back of the outer side of the pressure plate. A positioning rod is attached to the bottom of the magnetic card, and a magnetic plate is attached to the top of the magnetic card. The built-in structure is located inside the pressure plate. The built-in structure includes an inner cylinder, a cylinder groove, a side rotating plate, a pressure rod, a rocker arm, and a lifting rod. An inner cylinder is vertically positioned in the middle of the inner side of the pressure plate. Cylinder grooves are vertically formed on both sides of the outer surface of the inner cylinder. A pressure rod is attached to the upper end of the inner side of the cylinder groove. A side rotating plate is attached to the bottom of the pressure rod. A lifting rod is attached to the outer side of the side rotating plate. A rocker arm is attached to the top of the lifting rod. The side rotating plate and the lifting rod form a rotating structure, which allows the lifting rod to rotate slightly.

[0013] Furthermore, the pressure rod is composed of a cylindrical section and a thin cylindrical section. The area of ​​the cylindrical section at the upper end of the pressure rod is larger than the area of ​​the thin cylindrical section at the lower end of the pressure rod, which facilitates the pressure rod to drive the side rotating plate to rotate.

[0014] Furthermore, the side rotating plate is composed of a thin rotating rod and a flat rotating block. The flat rotating block of the side rotating plate is fixedly connected to the lifting rod, so that the lifting rod can be driven by the side rotating plate to move.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model uses an electric telescopic rod to move the contact plate forward. The push shafts on both sides of the contact plate move on the outside of the extension frame. At the same time, the rotating block can help adjust the rotation angle of the contact plate. When the contact plate moves forward, the curved piece moves with the contact plate. The curved piece drives the iron block and the grafting rod to pass through the vertical frame and approach the outside of the pressure plate. The magnetic card attracts and connects with the grafting rod and the iron block. After being pushed by the iron block and the grafting rod, the magnetic card is pressed against the outside of the pressure plate. The magnetic plate attracts the workpiece body. When the magnetic card and the magnetic plate apply force to the pressure plate, the pressure plate is forced to move the slider inside the track groove. At the same time, the spring reduces the range of movement of the pressure plate. In this way, when the electric telescopic rod moves the contact plate backward, the contact plate drives the iron block and the grafting rod to move backward. The grafting rod and the iron block drive the magnetic card and the magnetic plate to move backward. The magnetic plate attracts the workpiece body and moves backward. At this time, the workpiece body will be separated from the pressure plate.

[0017] 2. When the pressure cylinder applies pressure to the workpiece body, the bottom end of the workpiece body squeezes the pressure rod, the pressure rod presses the side rotating plate, the side rotating plate rotates after being stressed, the side rotating plate drives the lifting rod to rotate slightly, and the lifting rod drives the rocker plate to tilt to both sides. In this way, the middle part of the bottom end of the workpiece body is lifted by the rocker plate, increasing the contact degree between the workpiece body and the pressure cylinder, thereby increasing the pressure application effect of the pressure cylinder.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figures 1-6 As shown, an engine cylinder head gasket processing stamping device with a material ejection mechanism includes: a power box 1, a support 2 at the bottom of the power box 1, a vertical frame 16 on one side of the bottom of the support 2, a rectangular channel horizontally opened at the lower end of the surface of the vertical frame 16, a pressure cylinder 3 at the middle of the bottom of the support 2, an extension frame 12 at the bottom of the vertical frame 16, a first platform 8 at the top of the front end of the extension frame 12, a rail groove 9 at the middle of the top of the first platform 8, a spring 7 at the front end of the inner side of the rail groove 9, a slider 6 at one end of the spring 7, a pressure plate 5 at the top of the slider 6, and a workpiece body 4 at the top of the pressure plate 5.

[0027] An electric telescopic rod 17 is provided on the back of the extension frame 12. Rail rods 13 are provided on both sides of the front end of the extension frame 12. A push shaft 11 is provided on the outer side of the rail rod 13. A rotating block 15 is provided on the inner side of the push shaft 11. A touch plate 14 is provided on one side of the rotating block 15. A curved piece 10 is provided at the front end of the touch plate 14. An iron block 18 is provided at the front end of the curved piece 10. A grafting rod 19 is provided on the lower side of the front end of the curved piece 10. An auxiliary structure 20 is provided on the outer side of the pressure plate 5.

[0028] The rest, due to the pushing structure consisting of three contact plates 14, rotating blocks 15, push shafts 11, iron blocks 18, and grafting rods 19 on the surface of the extension frame 12, the pushing structure near the tail end of the extension frame 12 is driven by the electric telescopic rod 17 and moves forward on the surface of the extension frame 12. The iron block 18 and grafting rod 19 in the pushing structure near the pressure plate 5 attract the outer surface of the magnetic card 201. At the same time, after the iron block 18 squeezes the upper end of the magnetic card 201, the upper end of the magnetic card 201 is bent by force. At this time, the upper part of the magnetic card 201 drives the magnetic plate 202 to bend and move. The magnetic plate 202 attracts the workpiece. On the surface of the workpiece body 4, since the magnetic surface of the iron block 18 is magnetically connected to the contact plate 14, the electric telescopic rod 17 drives the push structure composed of the contact plate 14, rotating block 15, push shaft 11, iron block 18 and grafting rod 19 near the tail end of the extension frame 12 to move backward. At this time, the iron block 18 of the push structure composed of the contact plate 14, rotating block 15, push shaft 11, iron block 18 and grafting rod 19 will attract the contact plate 14 of the other contact plates 14, rotating block 15, push shaft 11, iron block 18 and grafting rod 19. In this way, the workpiece body 4 will be driven to move backward by the push structure composed of the magnetic plate 202 and the contact plate 14, rotating block 15, push shaft 11, iron block 18 and grafting rod 19, so that the workpiece body 4 is separated from the surface of the pressure plate 5.

[0029] This has resulted in the following effects and novel technologies:

[0030] This utility model engine cylinder head gasket processing stamping device achieves a highly efficient and automated production process through a carefully designed unloading mechanism. Its core lies in the power box 1 and its various components, which work together to complete the stamping and unloading process of the workpiece. The bracket 2 and vertical frame 16 constitute the support structure of the device, while the extension frame 12 at the bottom of the pressure cylinder 3 and curved plate 10 provides a stable platform for stamping. The rail groove 9 and spring 7 on the first platform 8 cooperate to maintain stable pressure on the slider 6 and pressure plate 5 during the stamping process, ensuring the forming quality of the workpiece body 4. The novelty lies in the electric telescopic rod 17 on the extension frame 12 driving the contact plate 14, rotating block 15, push shaft 11, iron block 18, and grafting rod 19 to form a pushing structure, enabling the workpiece body 4 to automatically unload after stamping. The iron block 18 and grafting rod 19 are magnetically attracted to the magnetic card. When the electric telescopic rod 17 drives the pushing structure to move backward, the workpiece body 4 held by the magnetic plate 202 is released from the pressure plate 5. The sliding connection between the slider 6 and the spring 7 and the elastic connection between the rail groove 9 and the slider 6 provide buffering for the stamping process, reducing impact, improving workpiece quality and equipment life. The magnetic attraction surface of the iron block 18 and the S-shaped curved plate 10 are designed to adapt to workpieces of different thicknesses. The pushing structure in the rectangular channel from the tail end of the extension frame 12 to the lower end of the surface of the vertical frame 16 is arranged in a stepped shape, which facilitates the mutual attraction between the iron block 18, the grafting rod 19 and the magnetic card 201, ensuring smooth material ejection. This utility model realizes automatic material ejection of workpieces through the pushing structure driven by the electric telescopic rod 17, which improves production efficiency, reduces labor intensity, and ensures workpiece quality and precision. It has high technical novelty and practical value.

[0031] like Figures 1-6 As shown, an engine cylinder head gasket processing stamping device with a material ejection mechanism includes an auxiliary structure 20 comprising a magnetic card 201, a magnetic plate 202, a positioning rod 203, and an internal structure 204. A magnetic card 201 is attached to the back of the outer side of the pressure plate 5. A positioning rod 203 is located at the bottom of the magnetic card 201, and a magnetic plate 202 is located at the top of the magnetic card 201. The internal structure 204 is located inside the pressure plate 5 and includes an internal cylinder 2041, a cylinder groove 2042, a side rotating plate 2043, and a pressure rod. 2044, rocker 2045, and lifting rod 2046; an inner cylinder 2041 is vertically arranged in the middle of the inner side of the pressure plate 5; cylinder grooves 2042 are vertically opened on both sides of the outer surface of the inner cylinder 2041; a pressure rod 2044 is arranged at the upper end of the inner side of the cylinder groove 2042; a side rotating plate 2043 is arranged at the bottom end of the pressure rod 2044; a lifting rod 2046 is arranged on the outer side of the side rotating plate 2043; a rocker 2045 is arranged at the top end of the lifting rod 2046; and a rotating structure is formed between the side rotating plate 2043 and the lifting rod 2046.

[0032] As the workpiece body 4 moves downward after being squeezed by the pressure cylinder 3, the two sides of the bottom end of the workpiece body 4 first squeeze the pressure rod 2044 to descend in the cylinder groove 2042 on both sides of the inner cylinder 2041. The bottom end of the pressure rod 2044 presses the side rotating plate 2043. After being stressed, the side rotating plate 2043 drives the lifting rod 2046 to rotate slightly. The lifting rod 2046 drives the rocker plate 2045 to tilt to both sides at the middle of the top of the inner cylinder 2041. This makes the rocker plate 2045 press against the middle of the bottom end of the workpiece body 4. The designer can change the shape of the rocker plate 2045. A semi-circular or flat rocker plate 2045 can increase the contact area with the bottom end of the workpiece body 4.

[0033] This has resulted in the following effects and novel technologies:

[0034] The auxiliary structure 20 of the engine cylinder head gasket processing stamping device of this utility model improves the processing accuracy of the workpiece body 4 and the pressure effect of the device through its ingenious design. The combination of magnetic card 201 and magnetic plate 202 ensures the fixation of the workpiece body 4 during the stamping process, while the innovative design of the built-in structure 204 achieves precise support for the bottom of the workpiece. When the pressure cylinder 3 applies pressure to the workpiece body 4, the bottom end of the workpiece squeezes the pressure rod 2044, and the bottom end of the pressure rod 2044 presses the side rotating plate 2043. After being stressed, the side rotating plate 2043 drives the lifting rod 2046 to rotate slightly. The lifting rod 2046 further drives the rocker plate 2045 to tilt to both sides and press against the middle of the bottom end of the workpiece body 4. This design increases the contact degree between the workpiece body 4 and the pressure cylinder 3. This design improves the pressure effect and ensures the consistency of workpiece forming. The cylindrical and thin cylindrical sections of the pressure rod 2044, as well as the thin rotating rod and flat rotating structure of the side rotating plate 2043, enable the pressure rod 2044 to effectively drive the side rotating plate 2043 to rotate, thereby making the movement of the lifting rod 2046 and the rocker 2045 more flexible. This rotating structure design facilitates precise support of the bottom of the workpiece body 4, and also facilitates the adjustment and replacement of rocker 2045 of different shapes to adapt to workpieces of different sizes and shapes. Through the innovative design of the auxiliary structure 20, this utility model achieves stable fixation and bottom support of the workpiece during the stamping process, improves processing accuracy and production efficiency, and has significant technological progress and novelty.

[0035] Working principle: When using the engine cylinder head gasket processing stamping device with a material ejection mechanism, the workpiece body 4 is first placed on the top of the pressure plate 5. The power box 1 drives the pressure cylinder 3 to descend and apply pressure at the bottom end of the support 2. The pressure cylinder 3 applies pressure to the surface of the workpiece body 4. The two sides of the bottom end of the workpiece body 4 first squeeze the pressure rod 2044. After the pressure rod 2044 presses the side rotating plate 2043, the side rotating plate 2043 drives the lifting rod 2046 to rotate slightly inside the cylinder groove 2042. 2046 drives the rocker arm 2045 to tilt upwards towards both sides of the top of the inner cylinder 2041. After the rocker arm 2045 tilts upwards, it pushes the bottom end of the workpiece body 4. When the workpiece body 4 is pressed by the pressure cylinder 3, the electric telescopic rod 17 drives the contact plate 14 to move forward. The push shafts 11 on both sides of the contact plate 14 move forward outside the extension frame 12. At the same time, the rotating block 15 can adjust the rotation angle of the contact plate 14. The contact plate 14 drives the push shafts 11 to move outside the rail rod 13. The curved section at the front end of the contact plate 14... Plate 10 moves iron block 18 forward, at which time iron block 18 pushes other contact plates 14 to move. The grafting rod 19 at the bottom of the curved plate 10 and the iron block 18 at the front end of the contact plate 14 near the pressure plate 5 attract the magnetic card 201. The top of the magnetic card 201 bends after being pushed by the iron block 18, and the magnetic plate 202 at the top of the magnetic card 201 attracts the top of the workpiece body 4. When the magnetic card 201 is pushed, it drives the pressure plate 5 to move. At the same time, the slider 6 at the bottom of the pressure plate 5 moves in the track groove 9. The inner side moves, the spring 7 reduces the range of movement of the slider 6, and after the electric telescopic rod 17 is restarted, it drives the contact plate 14 at the tail end of the extension frame 12 to move to the rear side. The contact plate 14 drives the curved piece 10, the iron block 18 and the grafting rod 19 to move to the rear side. The iron block 18 and the grafting rod 19 drive the magnetic card 201 and the magnetic plate 202 to move to the rear side. The magnetic plate 202 drives the workpiece body 4 to leave the surface of the pressure plate 5. This is the working principle of the engine cylinder head gasket processing stamping device with the material ejection mechanism.
