Embodiment 1

[0030] Embodiment one, see figure 1, a device for extruding burrs and finishing the outer diameter of a spoke air hole, comprising a lower mold base 1 and an upper mold base 2 . The spoke 5 includes a peripheral wall 51 and an end wall 52 connected to one end of the peripheral wall. The peripheral wall 51 is cylindrical. The peripheral wall 51 and the end wall 52 are integrally formed. The end wall 52 is provided with a central hole 53 and an air hole 54 .

[0031] The lower mold base 1 is provided with an extrusion ring 3 and a core 4 . The inner peripheral surface of the extrusion ring 3 is a tapered surface with a large upper end and a smaller lower end. The extrusion ring 3 and the core 4 are arranged coaxially. The outer peripheral surface of the core 4 is a tapered surface with a large upper end and a smaller lower end. The core 4 is provided with an extruding head 41 for extruding the wall of the wind hole. The diameter of the upper end of the core 4 is equal to ...

Embodiment 2

[0033] Embodiment two, the difference with embodiment one is:

[0034] see figure 2 , The lower mold base 1 is provided with a shock-absorbing structure 9 . The damping structure 9 includes a vertical damping cylinder 91 and a damping spring 92 sleeved on the damping cylinder. The damping oil cylinder 91 includes a damping oil cylinder body 911 . The damping cylinder body 911 is connected with the lower mold base 1. A first piston 912 is disposed inside the damping oil cylinder body 911 . The first piston 912 is connected to the supporting seat 93 through the piston rod 913 . One end of the damping spring 92 is affixed together with the piston rod 913, and the other end is affixed together with the cylinder body 911 of the damping oil cylinder.

[0035] The extrusion ring 3 is detachably connected with the lower die base 1 through bolts 11 and nuts 8 welded on the lower die base 1 .

[0036] see image 3 , The second piston 914 and the separation plate 94 are also prov...

Abstract

The invention relates to vehicle wheel manufacturing equipment, in particular to a spoke air hole burr extruding and outer diameter finishing device. The spoke air hole burr extruding and outer diameter finishing device comprises a lower mold seat and an upper mold seat. The lower mold seat is provided with an extruding ring and a core. The inner circumferential face of the extruding ring is a conical face with the upper end larger than the lower end. The extruding ring and the core are arranged coaxially. The outer circumferential face of the core is a conical face with the upper end larger than the lower end. The core is provided with an extruding head used for extruding the hole wall of an air hole. The diameter of the upper end of the core is equal to the inner diameter of the peripheral wall. A conical ring cavity capable of generating radial contraction when the peripheral wall is inserted in the conical ring cavity is formed between the core and the extruding ring. The upper mold seat is provided with an extruding disc for driving a spoke to move downwards. The spoke air hole burr extruding and outer diameter finishing device can shape the peripheral wall of the spoke and carry out burr extruding on the spoke air hole at the same time, and the problems that in the vehicle wheel production process, shaping of the peripheral wall of the spoke and burr extruding and removing of the air hole need to be achieved by two steps, and consequently the production efficiency is low are solved.

Description

technical field [0001] The invention relates to wheel manufacturing equipment, in particular to a device for extruding burrs and finishing outer diameters of spoke air holes. Background technique [0002] A wheel consists of a rim and spokes. The spokes include a cylindrical peripheral wall and an end wall connected to one end of the peripheral wall, and the end wall is provided with a central hole and an air hole. In the wheel manufacturing process, one tool is used to shape the peripheral wall of the rim to become a cylinder, and another tool is used to squeeze the air hole to remove burrs, so there is a problem of low production efficiency. Contents of the invention [0003] The invention provides a spoke air hole extruding burr and finishing outer diameter device capable of shaping the peripheral wall of the spoke and extruding the air hole at the same time, which solves the shaping of the peripheral wall of the spoke and the extrusion of the air hole during the produ...
