CN203683558U - Buffer cylinder of water squeezing stretcher - Google Patents

Abstract

The utility model discloses a buffer cylinder of a water squeezing stretcher. The buffer cylinder comprises an end cover, a plunger, a cylinder and a base, wherein a buffer plunger is arranged at one end of the plunger; a buffer ring capable of freely moving and a positioning ring used for spacing the buffer ring are arranged in the base, and the buffer plunger and the buffer ring are in clearance fit when the buffer cylinder works. According to the buffer cylinder of the water squeezing stretcher, quick ejection of the cylinder and gradual speed-reducing mode buffering in retraction can be realized due to the buffer ring arranged in the cylinder, the buffer plunger arranged at the right end of the plunger and a wedge-shaped inclined oil tank formed in the buffer plunger, the buffering impact is small, and the noise can be reduced; the buffer cylinder has the advantages of small size, high efficiency, long service life, compact structure and the like, and can be used for ensuring stable product quality, so that the working requirement for opening and closing a large rubber roller of the water squeezing stretcher can be met, and the economic benefit can be increased. The buffer cylinder has a good practicality.

Description

A kind of cushion cylinder of water squeezing striking-out machine

Technical field

The utility model relates to leather machine technical field, is specifically related to a kind of cushion cylinder of water squeezing striking-out machine.

Background technology

The large rubber roll of water squeezing striking-out machine closes roller and opens roller work is to be realized by the work of the oil cylinder that is arranged in machine two ends.Quick need to accomplish large rubber roll to working position time, need to there is buffering and be about to put in place while leaving working position, when plunger ejects, need fast, and retraction to have buffering while putting in place, impact reducing.

The buffering form of general oil cylinder mainly contains four kinds: plunger tpe buffering, cushion collar-type buffering, sphere buffering, detachable buffering.Though above four kinds of buffering methods can be realized certain buffering object, its structure formation or buffering method can not meet the job requirement of water squeezing striking-out machine completely.

Utility model content

Goal of the invention: for the deficiencies in the prior art, the purpose of this utility model is to provide a kind of cushion cylinder of water squeezing striking-out machine, while ejecting fast and bounce back, cushions in the mode of progressively slowing down to realizing oil cylinder, and shock absorbing power is little, reducing noise, meets user demand.

Technical scheme: in order to realize foregoing invention object, the technical solution adopted in the utility model is as follows:

A kind of cushion cylinder of water squeezing striking-out machine, comprise end cap, plunger, cylinder barrel and base, be provided with buffer plunger in described plunger one end, in described base, be provided with the buffering ring that can move freely and for buffering ring is carried out to spacing retaining ring, when work, described buffer plunger and buffering ring running fit.

On described buffer plunger, have the oblique oil groove of wedge shape.

On the cylindrical surface of described buffering ring, have some oil grooves.

Beneficial effect: have prior art to compare, the cushion cylinder of water squeezing striking-out machine of the present utility model, buffering ring is set in oil cylinder and establishes buffer plunger and have the oblique oil groove of wedge shape at plunger right-hand member, can not only effectively realize when oil cylinder ejects fast and bounces back and cushioning in the mode of progressively slowing down, shock absorbing power is little, reducing noise; Also there is the advantages such as volume is little, efficiency is high, the life-span is long, compact construction, effectively guarantee constant product quality, therefore can meet the job requirement of the large rubber roll folding of water squeezing striking-out machine roller, increase economic efficiency; There is good practicality, can produce good economic benefit and social benefit.

Fig. 2 is the local structure schematic diagram of plunger.

Fig. 3 is the structural representation of buffering ring.

Embodiment

Below in conjunction with accompanying drawing, the utility model is further described.

As shown in figures 1 and 3, the cushion cylinder of water squeezing striking-out machine, comprises end cap 1, plunger 2, cylinder barrel 3, retaining ring 4, buffering ring 5, base 6 and corresponding connecting parts and sealing member.Buffering ring 5 is arranged in base 6, can move freely, and the retaining ring 4 being arranged on base 6 plays restriction buffering ring 5 positions.Buffer plunger 7 running fit of the right-hand member of the endoporus of buffering ring 5 and plunger 2.As shown in Figure 2, on the buffer plunger 7 of plunger 2 right-hand members, have the oblique oil groove 8 of wedge shape.As shown in Figure 3, on buffering ring 5 cylindrical surface, have some oil grooves 9.

When the cushion cylinder of this water squeezing striking-out machine is worked, in the time that pressure oil enters from B mouth, promote buffering ring 5 and move to left, the oil groove 9 of a large amount of hydraulic efficiency oil on the cylindrical surface of buffering ring 5 passes through, promote plunger 2 and move to left, because the flow of hydraulic efficiency oil is large, so plunger can move to left with speed faster.In the time that pressure oil enters from A mouth, promote plunger 2 and move to right, buffering ring 5, under return pressure effect, moves to right and is close to base 6, hydraulic efficiency oil in oil back chamber directly flows out from B mouth through the endoporus of buffering ring 5, in the oil groove 9 that oil return can not be opened from buffering ring 5 cylindrical surface, passes through.When plunger 2 approaches right-hand member, the buffer plunger 7 of plunger 2 right-hand members progressively enters the endoporus of buffering ring 5, and now oil return is flowed out from B mouth with the gap that the endoporus of buffering ring 5 forms through the buffer plunger 7 of plunger 2 right-hand members.Now flow reduces, and has reduced the speed that moves to right of plunger.Because the buffer plunger of plunger 2 right-hand members has the oblique oil groove 8 of wedge shape, the gap oil mass that the buffer plunger of plunger 2 right-hand members and the endoporus of buffering ring 5 form of flowing through is fewer and feweri, the speed that plunger 2 moves to right is more and more slower, instead of moves to right in mode at the uniform velocity, until plunger 2 stops.

Water squeezing striking-out machine cushion cylinder device of the present utility model, because the setting of buffering ring 5 and the buffer plunger of plunger 2 right-hand members have the oblique oil groove of wedge shape.Realized when oil cylinder ejects fast and bounces back and having cushioned in the mode of progressively slowing down, shock absorbing power is little, reducing noise.Have that volume is little, efficiency is high, the life-span is long, compact construction, etc. advantage, effectively guarantee constant product quality, therefore can meet the job requirement of the large rubber roll folding of water squeezing striking-out machine roller, improved economic benefit.
