DETAILED DESCRIPTION

[0028] The following will be combined with the attached Figures 1-3 The utility model is further explained in detail.

[0029] Embodiment one

[0030] As Figures 1-3 Indicated, in order to be able to solve the existing problem in the present embodiment, the utility model discloses a kind of pipe shrinking structures for motorcycle shock absorber production, including base 1 and its top is connected with support support 2, support support 2 top is rotatably connected with roller 3, base 1 top is connected with pushing part 4, base 1 top is connected with pressing part 5, base 1 top is connected with extrusion part 6.

[0031] The pushing part 4 includes the telescopic rod support 401 with the top of the base 1, the telescopic rod support 401 top is connected with electric telescopic rod 402, and the telescopic end of the electric telescopic rod 402 is connected with sliding support 403, and the bottom of the sliding support 403 is slidably connected with the top of the base 1 through sliding support column.

[0032] The sliding support 403 side is connected with motor support, and the motor support is connected with rotating motor 404, and the output end of the rotating motor 404 is connected with rotating sleeve 405 penetrating sliding support 403, and the rotating sleeve 405 is rotatably connected with sliding support 403.

[0033] The pressing component 5 includes a support column 501 connected to the top of the base 1. A top bracket 502 is connected to the top of the support column 501. A lifting electric telescopic rod 503 is connected to the top of the top bracket 502. A lifting component 504 is connected to the bottom telescopic end of the lifting electric telescopic rod 503. The two ends of the lifting component 504 are slidably connected to the support column 501. An arc-shaped pressing component 505 is connected to the bottom of the center of the lifting component 504.

[0034] The specific working principle is as follows: This device can effectively improve the stability of steel pipe shrinking processing. At the same time, compared with traditional devices, this device avoids rigid collision between the device and the side of the steel pipe by rotating and extruding, thereby ensuring the service life of the device.

[0035] When using this device, the steel pipe raw material is placed above the roller 3. At this time, the rotating sleeve 405 in the pushing component 4 is connected to one end of the steel pipe. The rotating motor 404 can drive the steel pipe to rotate, and the structure of the electric telescopic rod 402 can drive the steel pipe to slide.

[0036] While the steel pipe is rotating and sliding, the electric telescopic rod 503 is activated, which drives the lifting component 504 to slide downward, so that the arc-shaped pressing component 505 contacts the side of the steel pipe, thereby preventing the steel pipe from jumping when rotating and improving the stability of the steel pipe transmission.

[0037] When the steel pipe rotates, rotating the lifting threaded rod 603 allows the lifting connector 604 to slide vertically, thereby causing the extrusion roller 607 to slide up and down. When the end of the extrusion roller 607 close to the inclined bracket 605 contacts the steel pipe, rotating the inclined threaded rod 608 causes the extrusion roller 607 to tilt, thereby achieving a conical extrusion effect on one end of the steel pipe, thus realizing the pipe shrinking processing effect of this device.
