Be equipped with in the die 1 with the recess 2 of fashioned automobile sleeve one end outer wall matching, traditional recess 2 is the straight hole, automobile sleeve outer wall after the punching press does not take place any change, and the recess 2 of this device adopts the shape that needs to process one end outer wall complete matching with automobile sleeve, and recess 2 lower extreme diameter is little, the upper end diameter is big, and bottom and transition department set up the chamfer. After the punching press like this, except that the annular recess of an extra processing of automobile sleeve outer wall, other needs the multichannel chamfer to be chamfered all need not to process once more.
As shown in fig. 3-4, the lower part of the automobile sleeve also needs to be punched, so that a lower punch 6 is arranged in the cylinder 5, and the upper part of the lower punch 6 is matched with the inner hole of the automobile sleeve and partially extends into the groove 2. After the upper die is pressed down, the lower punch 6 can punch the lower part of the automobile sleeve. The bottom end of the lower punch 6 is a large-diameter cylinder, after the large-diameter cylinder is nested with a counter sink on the lower punch fixing seat 7, the lower punch fixing seat 7 is arranged on the lower punch supporting seat 13, a central hole in the bottom of the lower punch supporting seat 13 is nested with the ejection pile sleeve 14, and the ejection pile sleeve 14 is arranged on a positioning hole of the workbench 15. And a material returning sleeve 8 is arranged outside the middle section of the lower punch 6 in a sliding manner, and the material returning sleeve 8 is used for ejecting the automobile sleeve out of the female die 1 after the punching is finished. Three groups of ejector rods 9 are arranged in an inner center hole of the lower punch supporting seat 13, a through hole for the ejector rod 9 to pass through is correspondingly formed in the top end of the lower punch supporting seat 13, the upper end of the ejector rod 9 freely passes through the lower punch supporting seat 13 and the lower punch fixing seat 7, and the upper end of the ejector rod 9 is connected with the material returning sleeve 8. The lower end of the mandril 9 is connected with a driving device 10. The driving device 10 comprises a material ejecting pile 16, the material ejecting pile 16 is a T-shaped rod, the large end of the T-shaped rod is located in the inner central hole of the lower punch supporting seat 13, the small diameter end of the material ejecting pile 16 penetrates through a material ejecting pile sleeve 14 and then is connected with a hydraulic cylinder, and the material ejecting pile 16 is driven to move up and down through the expansion of the hydraulic cylinder.
As shown in fig. 2-3, the inner hole of the stress ring 3 is provided with a cooling water channel 11, the cooling water channels 11 are distributed in an annular shape, the stress ring 3 is provided with water diversion holes for inlet and outlet along the radial direction, and the water diversion holes are connected with an external water supply and outlet device through hoses.
