Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
As shown in Figures 1 to 3, a kind of new casing Plastic renovation device of the utility model, including hanging ring 1, upper binding head 2,
Hydraulic cylinder 3, lower union joint 4, piston 5, piston rod 6, shaping head 7, upper linking arm 8, lower linking arm 9, shaping roller 10, upper arm pegs
Follow closely 11, idler wheel pin 12, lower arm pin 13, the first sealing ring 14, the second sealing ring 15, upper sealing ring 16, lower sealing ring 17, spiral shell
Nail 18, the hanging ring 1 is fixedly mounted on 2 upper end of upper binding head, and 2 lower end of upper binding head is threadedly coupled with hydraulic cylinder 3, described
Upper runner A is offered on upper binding head 2,6 upper end of piston rod is threadedly coupled with piston 5, and lower end and 7 screw thread of shaping head connect
It connects, first sealing ring 14 is mounted on the outside of piston 5, and the piston 5 is sleeved on 3 inside of hydraulic cylinder and divides hydraulic cylinder 3
For upper and lower two cavitys, the upper runner A is connected with the upper chamber of hydraulic cylinder 3, and the lower union joint 4 is pacified by screw 18
Mounted in 3 lower end of hydraulic cylinder, lower flow channel B, the lower cavity phase of the lower flow channel B and hydraulic cylinder 3 are offered on the lower union joint 4
