Abstract
The utility model relates to metal forming machinery equipment, in particular to a closing height adjusting mechanism of press which belongs to the technical field of machinery equipment processing and comprises a circle of cylindrical pin rollers additionally arranged between a gland and a screw to form rolling friction; the contact between the gland and the screw is not plane contact; the closing height adjusting mechanism of press reduces the friction between the contact surface of the screw and the gland during the process that a worm drives the screw to rotate, eliminates the damage between the contact surface of the screw and the gland, is beneficial for stabilizing the gravity of a sliding block, and plays a certain role of guaranteeing the precision of the press.
Description
Technical field
The utility model relates to a kind of forging machinery and equipment, is specifically related to a kind of pressure machine closed height adjustment mechanism, belongs to the plant equipment processing technique field.
Background technology
At present, in the metal forming machinery industry, the closed height governor motion of installing on the straight side press is directly screw rod to be fixed on the piston with a gland, is plane contact between gland and the screw rod, and piston keeps off in oil cylinder inside with block, by screw oil cylinder is fixed on the slide block again, screw rod is connected with key with worm gear, drives worm gear and rotate under the effect of worm screw in external force, and the rotation of worm gear drives screw rod and rotates in the connecting rod the inside, move up and down thereby driven slide block, reach the purpose of regulating closed height.Because screw rod is in rotation process, be plane contact between gland and the screw rod, its friction is sliding friction, frictional force is very big, often cause the infringement of contact-making surface between screw rod and gland, thereby strengthened the slide block internal clearance, caused between slide block baseplane and working plate the depth of parallelism overproof, the forcing press precision also decreases.
Summary of the invention
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art part, a kind of pressure machine closed height adjustment mechanism is provided, this mechanism is included in has increased by all cylinder rollers between gland and the screw rod, form rolling friction, no longer plane contact between gland and the screw rod, it reduces the friction between screw rod and gland contact-making surface in worm gear drives screw rod rotating process, eliminate the infringement of screw rod and gland contact-making surface, the center of gravity of favourable and slide block steadily, the precision that guarantees forcing press is played a role.
The utility model is realized with following technical scheme: a kind of pressure machine closed height adjustment mechanism, it includes by screw and is fixed on oil cylinder on the slide block, piston is arranged in the oil cylinder, block is arranged on the piston, gland is fixed on screw rod on the piston, it is characterized in that: between described gland and the screw rod cylindrical rollers is arranged, and spacing by retainer, screw rod connects worm gear by key, and worm gear connects worm screw.
Described oil cylinder one end is a ring flange square shape, and screw hole is arranged all around, is fixed on the slide block by screw, and oil cylinder is made stepped hole along the center, and piston and block are installed respectively.
Advantage of the present utility model: owing to adopted said structure, no longer be plane contact between gland and the screw rod, but between gland and screw rod, increased by all cylindrical rollers, form the line contact, rolling friction.Reduce the friction between screw rod and gland contact-making surface in worm gear drives screw rod rotating process, eliminate the infringement of screw rod and gland contact-making surface, the center of gravity of favourable and slide block steady plays a role to the precision of assurance forcing press.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described in further detail:
Fig. 1 is the utility model structural representation:
Fig. 2 is the cross sectional plan view of Fig. 1 at the B-B place:
Among the figure: 1, connecting rod, 2, screw rod, 3, retainer, 4, gland, 5, screw, 6, block, 7, roller, 8, piston, 9, oil cylinder, 10, slide block, 11 screws, 12, key, 13, worm gear, 14, worm screw.
The specific embodiment
As shown in the figure: a kind of pressure machine closed height adjustment mechanism, it includes by screw 11 and is fixed on oil cylinder 9 on the slide block 10, piston 8 is arranged in the oil cylinder, block 6 is arranged on the piston, gland 4 is fixed on screw rod 2 on the piston 8, between described gland 4 and the screw rod 2 cylindrical rollers 7 is arranged, and spacing by retainer 3, screw rod 2 connects worm gear 13 by key 12, and worm gear connects worm screw 14.
Described oil cylinder 9 one ends are ring flange square shape, and screw hole is arranged all around, are fixed on the slide block 10 by screw 11, and oil cylinder 9 is made stepped hole along the center, piston 8 and block 6 are installed respectively.
The course of work: this closed height governor motion is fixed on oil cylinder 9 on the slide block 10 of forcing press by screw 11, piston 8 usefulness blocks 6 are limited in the oil cylinder 9, screw rod 2 is limited on the piston 8 by gland 4 usefulness screws 5, middle useful retainer 3 is limited to the cylindrical rollers 7 in a week on the screw rod 2, and worm gear 13 usefulness keys 12 are connected with screw rod.Under the effect of worm screw 14, drive worm gear 13 and rotate, drive screw rod 2 by worm gear 13 and rotate, move up and down, reach the purpose of regulating closed height thereby drive slide block 10 in connecting rod 1 the inside in external force.Owing between gland 4 and screw rod 2, increased by all cylindrical rollers, form rolling friction, the power of reducing friction in worm gear drives screw rod rotating process is eliminated the infringement of screw rod and gland contact-making surface, the center of gravity of favourable and slide block steady.The machine precision helps keep-uping pressure.
