[0002] The engine flywheel housing is one of the key components of the engine, located between the end of the engine crankshaft and the transmission. The flywheel housing is the outer shell that wraps the flywheel, generally composed of two half-shells, and fastened together by bolts or rivets. The main functions of the flywheel housing are to protect the flywheel, crankshaft and transmission system, and reduce the vibration and noise of the engine.
[0003] Generally, when punching the flywheel housing, it needs to be placed on the die for fixation to prevent the flywheel housing from shaking. It is rather troublesome to fix the flywheel housing with a fixing jig, and it is also necessary to manually loosen and tighten the jig to fix the die, which delays the processing efficiency. Therefore, we propose a punching die for a flywheel housing to solve the problems mentioned above. Content of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.
[0022] Please refer to Figures 1-4 , an embodiment provided by the present invention: a flywheel housing punching die, including a base 1 and a mold rack 3, and the mold rack 3 is arranged at the upper end of the base 1;
[0023] It further includes:
[0024] A bracket 2, which is arranged at the upper end of the base 1. At the upper end inside the bracket 2, there is a cylinder 4. At the bottom of the cylinder 4, there is a telescopic rod 6, and the cylinder 4 drives the telescopic rod 6 to perform telescopic movement. At the bottom of the telescopic rod 6, there is a punching head 20. Outside the telescopic rod 6, there is a cross plate 5. On both sides of the cross plate 5, there are symmetrically arranged fixed rods 7. At the bottom of the fixed rods 7, there is a ring 11. At the openings at both ends of the ring 11, there are symmetrically arranged slide plates 13. The slide plates 13 swing at the openings at both ends of the ring 11 through a rotating shaft 14. Outside the slide plates 13, there is a swing plate 10. At the outer side of the bottom of the swing plate 10, there is a clamping plate 9, and the clamping plate 9 is arranged in an arc shape.
[0025] When the cylinder 4 drives the punching head 20 to descend, the swing plate 10 first contacts the surface of the flywheel housing. When the swing plate 10 contacts the flywheel housing, it closes the clamping plate 9 inward, so that the clamping plate 9 fixes the outside of the flywheel housing, and makes the ring 11 fit on the upper end of the flywheel housing and perform limiting. Since the fixed rods 7 are movably clamped on both sides of the cross plate 5, the continuous descent of the punching head 20 will not be hindered, so that the surface of the flywheel housing can be punched.
[0026] Please refer to Figure 2 , on both sides of the cross plate 5, there are symmetrically arranged first round holes 18, and the fixed rods 7 are slidably clamped inside the first round holes 18. Outside the fixed rods 7, there is a spring 8, so that the fixed rods 7 can move up and down at both ends of the cross plate 5.
[0027] Please refer to Figure 2 , at the upper end of the fixed rod 7, there is a limit block 19, and the limit block 19 is located at the upper end of the cross plate 5 to limit the position of the fixed rod 7.
[0028] See also Figure 4 A slide groove 15 is provided in the middle of the swing plate 10, and the slide plate 13 is slidably engaged in the inside of the slide groove 15, so that the spacing between the clamping plates 9 can be understood.
