Description

Technical Field

[0001] The utility model belongs to the technical field of engine parts stamping fixtures, in particular to a stamping fixture device for engine cylinder head parts. Background Art

[0002] Engine cylinder head accessories are an important category of automotive accessories, involving a variety of different products and specifications, such as cylinder gaskets, crankshaft oil seals, valve clearance adjustment screws, valve seat sealing gaskets, etc. The sealing gasket accessories used when installing the engine cylinder head are mainly used to seal the intake / exhaust valves, and the engine sealing gaskets often require stamping technology during manufacturing. The stamping process mainly includes material cutting, punching, punching, shaping, heat treatment, cleaning and packaging.

[0003] After searching, a Chinese patent with publication number CN217861688U discloses a punching device for processing engine gaskets, including a support frame, both ends of the support frame are connected to screws through mounting blocks, and a driving assembly is installed on the screw between the mounting blocks; a rotating bearing mechanism is installed at the bottom of the support frame; the rotating bearing mechanism includes a rotating rod rotatably connected to the support frame, one end of the rotating rod is connected to the screw through a transmission assembly, and the other end is fixedly provided with a mounting seat, the bottom of the mounting seat is provided with an opening, and a dust suction mechanism is installed on the support frame located at the bottom of the opening; an elastic clamping mechanism is installed on the top of the support frame; the elastic clamping mechanism includes a sliding member slidably connected to the support frame.

[0004] Through the above-mentioned prior art, we can understand that during the processing of the engine cylinder head gasket, a clamping mechanism is needed to clamp and fix the gasket before stamping. However, in actual operation, we find that in order to facilitate the stamping of the punching rod, the clamping mechanism in the prior art can only clamp around the center of the sealing gasket that needs to be stamped. Since the stamping hole of the sealing gasket cannot be completely clamped and fixed, during stamping, the edge of the sealing gasket is affected by the elasticity of the material, resulting in poor product effect.

This is because the hydraulic oil is affected by the pressure in the hydraulic cylinder, and then transmitted to the piston rod, thereby generating thrust, which is a prior art product;

[0025] The clamping mechanism 4 includes a bracket 402, which is symmetrically fixedly mounted on the upper end of the assembly plate 6. A first electric push rod 401 is fixedly mounted on the upper end of the bracket 402. The output ends of the first electric push rod 401 all penetrate the bracket 402 and are fixedly mounted with the same movable clamp 403. A fixed clamp 405 is fixedly mounted on the upper end of the assembly plate 6. The movable clamp 403 is arranged directly above the fixed clamp 405. A positioning hole 406 is opened on the upper end of the movable clamp 403. A punching hole 404 is opened on the inner side of the movable clamp 403 and the fixed clamp 405. One end of the punching hole 404 extends downward and penetrates the assembly plate 6. The sealing gasket to be punched is positioned along the positioning mechanism 5 and placed in the fixed clamp 405. Then, the output end of the first electric push rod 401 on the bracket 402 is synchronously extended and retracted to make the movable clamp 403 connected to the output end of the first electric push rod 401 move toward the fixed clamp 405 and cooperate with the positioning hole 406 to penetrate the positioning mechanism 5 and then cooperate with the fixed clamp 405 to clamp the entire sealing gasket, and then use the punch head 3 on the output end of the hydraulic rod 2 to punch the punching hole 404 aligned with the movable clamp 403 and the fixed clamp 405.

When positioning, the output end of the second electric push rod 503 extends out to push the mounting plate 504 to slide on the inner side of the square sleeve 502. At the same time, the positioning columns on the mounting plate 504 501 slides upward through the square sleeve 502 and the assembly plate 6, and extends out from the center of the fixed clamp 405. At this time, the processing personnel can put the sealing gasket into the positioning column 501 to position it into the fixed clamp 405. Then, when clamping, the dynamic clamp 403 passes through the upper end of the positioning column 501 through the positioning hole 406, so that the dynamic clamp 403 and the matching fixed clamp 405 can clamp the sealing gasket in all directions. After the stamping is completed, the output end of the second electric push rod 503 retracts and drives the mounting plate 504 with the positioning column 501 to slide down at the square sleeve 502 to the same level as the upper surface of the fixed clamp 405. At this time, the stamped sealing gasket can be quickly unloaded and removed.

[0032] Principle and advantages of use: When punching the sealing gasket, the output end of the second electric push rod 503 extends out to push the mounting plate 504 to slide inside the square sleeve 502. At the same time, the positioning column 501 on the mounting plate 504 slides upward to penetrate the square sleeve 502 and the assembly plate 6, and extends out from the center of the fixed clamp 405. At this time, the processing personnel put the sealing gasket into the positioning column 501 to position it and put it into the fixed clamp 405. The output end of the first electric push rod 401 on the bracket 402 is synchronously extended and retracted to make the dynamic clamp 403 connected to the output end of the first electric push rod 401 move toward the fixed clamp 405 and cooperate with the positioning hole 406 to penetrate the positioning column 501 and then cooperate with the fixed clamp 405 to clamp the entire sealing gasket. Then, the punch head 3 on the output end of the hydraulic rod 2 is used to punch the punching hole 404 aligned with the dynamic clamp 403 and the fixed clamp 405. The punch head 3 extends in the direction of the punching hole 404 and penetrates the assembly plate 6 to discharge the waste and complete the punching.

[0033] After stamping is completed, the output end of the second electric push rod 503 retracts to drive the mounting plate 504 with the positioning column 501 to slide down the square sleeve 502 to the same level as the upper surface of the fixed fixture 405. At this time, the stamped sealing gasket can be quickly unloaded and taken out.
