Embodiment 1

[0034] Such as Figure 1-4 As shown, an automobile shock absorber working cylinder expansion package tooling includes an upper die set 1, a lower die set 8, and a bottom die set 32.

[0035] The upper module 1 includes a top plate 2, a guide sleeve 4, and a centering head 6. The guide sleeve 4 is fixed on the lower surface of both ends of the top plate 2 by a screw one 3, and the centering head 6 is sleeved on the screw two 7. And can slide up and down, the second screw 7 is screwed in the center of the lower surface of the top plate 2, a compression spring 5 is set between the centering head 6 and the top plate 2, the second screw 7 is 10 cm long, the The effective stroke of compression spring 5 is 6 centimetres.

[0036] Described lower mold group 8 comprises connecting plate 9, column 10, punch seat 11, punch 13, punch cover 17, die 16, and the lower end of described column 10 is screwed on the two ends of described connecting plate 9, The upper end of the column 10 is sl...

Embodiment 2

[0048] The structure of this embodiment is basically the same as that of Embodiment 1, the difference is that a through hole is set at the corresponding position of the top plate 2 in the center of the inner hole top surface of the guide sleeve 4, and the inner cavity of the guide sleeve 4 passes through the through hole to connect with the outside of the hole. In communication, when the guide sleeve 4 and the column 10 move relative to each other, adjusting the pressure in the inner cavity of the guide sleeve 4 can make the column 10 move more smoothly in the inner hole of the guide sleeve 4 .

Embodiment 3

[0050] The structure of this embodiment is basically the same as that of Embodiment 1, the difference being that the top edge of the punch seat 11 is chamfered at 45 degrees, which facilitates the positioning of the inner hole of the working cylinder 31 and prevents damage to the inner wall of the working cylinder 31 .

Abstract

The invention relates to a vehicle shock absorber working cylinder expanding tool, which comprises an upper module, a lower module and a bottom module. The upper module is fixed to an upper jacking plate of a hydraulic machine, the bottom module is fixed to a workbench of the hydraulic machine, the bottom module is provided with an expanding rod with the conical top, and a male die seat is provided with a male die composed of three sections; through relative movement of the upper module, the lower module and the bottom module, the sectioned male die is jacked open through the conical expandingrod, and through matched using of a female die, a workpiece can be expanded to form the needed shape; and a to-be-machined working cylinder is automatically clamped, operation is easy, the time and labor are saved, and the machining quality is stable.

Description

technical field [0001] The invention relates to the technical field of automobile shock absorber working cylinder processing, in particular to an automobile shock absorber working cylinder expansion packing tool. Background technique [0002] In mechanical equipment, metal tubes are important parts that are widely used. The working cylinder of automobile shock absorber is a thin-walled tube cylindrical material, which requires high machining accuracy and is not easy to process. At present, it is necessary to purchase a special Processing equipment has high production cost, complicated process, low production efficiency and low equipment utilization rate. [0003] The Chinese patent with the authorized announcement number CN 201304450 Y discloses a kind of expansion mold of shock absorber oil storage cylinder, which is composed of guide lifting assembly, oil storage cylinder clamping and positioning mechanism, upper mold assembly, lower mold assembly and upper and lower mold ...
