Abstract
The invention relates to a nitrogen cylinder for a plate shearing machine, comprising a cylinder body, a guiding sleeve and a piston rod. One end of the piston rod is disposed in the cylinder body; the guiding sleeve is arranged between the cylinder body and the piston rod. The nitrogen cylinder for the plate shearing machine is characterized in that the cylinder body and the guiding sleeve are of an integral structure. The nitrogen cylinder for the plate shearing machine is few in leaking points of the cylinder body, long in service life and low in manufacturing cost.
Description
Technical field
The present invention relates to a kind of cylinder, specifically, relate to a kind of guillotine shear nitrogen cylinder.
Background technique
Existing cylinder, especially guillotine shear adopt split-type structural (as shown in Figure 1) mostly with the cylinder body and the guide sleeve of nitrogen cylinder, and the material of cylinder body is 45#, and the guide sleeve material is ZQSN10-1.This structure relies on the guide sleeve guiding, because guide sleeve is a thin-wall part, easily deforms in course of working, and increase the leak point of cylinder body, and the material price of guide sleeve is also relatively more expensive.Therefore, need a kind of new technological scheme to solve above-mentioned technical problem.
Summary of the invention
The objective of the invention is for solving the problems of the technologies described above, provide that a kind of cylinder body leak point is few, the guillotine shear nitrogen cylinder of long service life and low cost of manufacture.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
Guillotine shear nitrogen cylinder comprises cylinder body, guide sleeve and piston rod, and an end of described piston rod places in the cylinder body, and described guide sleeve places between cylinder body and the piston rod, and described cylinder body and guide sleeve are an overall structure.
Be provided with many guidance tapes between described guide sleeve and the piston rod.
The bar number of described guidance tape is three.
Described guidance tape is composited by polytetrafluoroethylmaterial material and bronze material.
Cylinder body of the present invention and guide sleeve are whole processing, have saved the copper material guide sleeve.Reduce the leakage point of cylinder body, improved the quality of cylinder body, saved manufacture cost.
Be provided with many guidance tapes between guide sleeve and piston rod, the guiding of cylinder body and piston rod is brought realization by guiding.And guidance tape is by the polytetrafluoroethylene PTFE material and bronze material is compound makes, and has enough intensity and wear-resisting property, can protect piston rod effectively, improves working life.
Advantage of the present invention is: the cylinder body leak point is few, long service life, low cost of manufacture.
Description of drawings
Fig. 1 is the result schematic diagram of existing nitrogen cylinder.
Fig. 2 is an overall structure schematic representation of the present invention.
Wherein: 1, cylinder body, 2, guide sleeve, 3, piston rod, 4, guidance tape.
Embodiment
As shown in Figure 2, guillotine shear nitrogen cylinder comprises cylinder body 1, guide sleeve 2 and piston rod 3, one end of piston rod 3 places in the cylinder body 1, and guide sleeve 2 places between cylinder body 1 and the piston rod 3, and cylinder body 1 adopts an overall structure with guide sleeve 2, like this, saved the copper material guide sleeve.Reduce the leakage point of cylinder body 1, improved the quality of cylinder body 1, saved manufacture cost; And between guide sleeve 2 and piston rod 3, be provided with three guidance tapes 4; each guidance tape 4 is composited by polytetrafluoroethylmaterial material and bronze material; cylinder body 1 leans on guidance tape 4 to realize with the guiding of piston rod 3; and guidance tape 4 is by the polytetrafluoroethylene PTFE material and bronze material is compound makes; have enough intensity and wear-resisting property; can protect piston rod effectively, improve working life.
Claims (4)
