Abstract

The utility model discloses a balance cylinder shock absorption device in the field of a pressure machine. The balance cylinder shock absorption device comprises a piston and a piston rod, wherein the piston and the piston rod are glidingly arranged in a cylinder body, the end part of the piston rod is provided with a ball head, a step is formed between the ball head and the piston rod, the middle part of the piston is provided with a cone groove corresponding to the ball head, the ball head is arranged in the cone groove through a press cover in a pressed way, the end part of the piston rod is connected with the piston through the press cover, an elastic component is arranged between the ball head and the press cover, and the elastic component is sheathed on the piston rod. The balance cylinder shock absorption device has the advantages that the elastic component is arranged between the piston rod and the piston, the noise in the work process of the pressure machine is reduced, the work environment of the pressure machine is optimized, the service life of the pressure machine is prolonged, and the balance cylinder shock absorption device can be used in the pressure machine.

Description

A kind of compensating cylinder damping device
Technical field
The utility model relates to a kind of compensating cylinder, particularly a kind of compensating cylinder damping device.
Background technology
Continuous upgrading along with forcing press production technology, market is also more and more higher to the requirement of forcing press, also day by day obvious to the requirement of machine noise, existing compensating cylinder is owing to being sphere-contact between piston rod and piston, therefore there is gap, in machine tool motion process, can produce noise, form noise pollution.
Utility model content
The purpose of this utility model is to provide a kind of compensating cylinder damping device, has reduced the noise in the course of work, optimizes the working environment of forcing press, extends its service life.
The purpose of this utility model is achieved in that a kind of compensating cylinder damping device, comprise the piston and the piston rod that are slidably arranged in cylinder body, described piston rod end is provided with bulb, between bulb and piston rod, form step, described piston middle part is provided with the cone groove corresponding with described bulb, described bulb is in gland is pressed on cone groove, the end of described piston rod links together through gland and piston, between described bulb and gland, be provided with elastomeric element, described elastomeric element is set on piston rod.
As improvement of the present utility model, described elastomeric element is nylon jacket.
As improvement of the present utility model, described elastomeric element is spring.
As improvement of the present utility model, described gland is fixed on piston through lock-screw.
As improvement of the present utility model, the thickness of described elastomeric element is 1/3 ~ 1/2 of cone groove depth.
In the utility model when work,, when piston rod moves up and down, owing to adopting the good nylon interplanting of elasticity filler, make the gap of piston rod and piston space less, therefore the collision of generation also relatively a little less than, the noise of generation is eliminated substantially; Secondly while adopting sphere-contact structure to prevent that piston rod from moving up and down between piston rod and piston, the perpendicularity of the relative piston of stroke of piston rod is compared with large and cause compensating cylinder to damage.Compared with prior art, the beneficial effects of the utility model are, the utility model is by between piston rod and piston, elastomeric element being set, and the noise while reducing forcing press work is optimized the working environment of forcing press, extends its service life.The utility model can be used in forcing press.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Wherein, 1 cylinder body, 2 piston rods, 3 lock-screws, 4 glands, 5 elastomeric elements, 6 bulbs, 7 pistons.
The specific embodiment
A kind of compensating cylinder damping device as shown in Figure 1, comprise the piston 7 and the piston rod 2 that are slidably arranged in cylinder body 1, piston rod 2 ends are provided with bulb 6, between bulb 6 and piston rod 2, form step, piston 7 middle parts are provided with the cone groove corresponding with bulb 6, bulb 6 is in gland 4 is pressed on cone groove, the end of piston rod 2 links together through gland 4 and piston 7, between bulb 6 and gland 4, be provided with elastomeric element 5, elastomeric element 5 is set on piston rod 2, elastomeric element 5 is nylon jacket, gland 4 is fixed on piston 7 through lock-screw 3, the thickness of elastomeric element 5 is 1/3 ~ 1/2 of cone groove depth.
During the utility model work, between piston rod 2 and gland 4, increase the good nylon jacket of elasticity and play cushioning effect, old-fashioned piston 7 adopts sphere-contact with piston rod 2, gap is larger, easily produce noise, if come the gap between control piston bar 2 and piston 7 by increasing the length of gland 4, owing to being that rigidity material contacts between gland 4 and piston 7, sphere-contact between piston 7 and piston rod 2 is just ineffective like this, piston rod 2 will damage running into the situation that stroke and piston 7 end face squareness are larger, and between piston rod 2 and gland 4, add a good nylon jacket of elasticity, so both guaranteed to reduce the gap between piston 7 and piston rod 2, and nylon jacket is out of shape under stressing conditions, make the piston rod 2 can be in activity under unfavorable condition freely, also replaceable one-tenth spring of nylon jacket in addition.
The utility model is not limited to above-described embodiment; on the basis of the disclosed technical scheme of the utility model; those skilled in the art is according to disclosed technology contents; do not need performing creative labour just can make some replacements and distortion to some technical characterictics wherein, these replacements and distortion are all in protection domain of the present utility model.
