Abstract
The invention relates to an automatic locking device for a piston cylinder of an upper roller system, which is used for automatically locking and loosening the upper roller system and a ram of metal plate strip multi-roller straightening equipment. The device comprises an upper working roller system, an upper roller system bottom plate and the ram, wherein a piston cylinder fixing bracket is fixed on the ram; the piston cylinder is connected with the piston cylinder fixing bracket; and a jacking head for directly automatically locking and loosening the upper roller system and the ram is arranged in the piston cylinder. The piston cylinder fixing bracket is fixed on the ram and can vertically move along with the ram, so that the piston cylinder can ensure that the upper roller system and the ram are automatically, quickly, reliably and safely locked and loosened through a short travel, the device has a simple structure and small volume, and locking force is 1.7 times that of the conventional structure.
Description
Technical field
The present invention relates to iron and steel and non-ferrous metal industry technical field, is that a kind of top roll that is used for metal plate and belt multiple roll equipment for straightening is the piston cylinder forced locking device specifically.
Background technology
Multi-roll straightening machine is widely used at iron and steel and non-ferrous metal industry as the equipment for straightening of metal plate and belt.System generally all can separate with main frame automatically at the multi-roll straightening machine central roll; Convenient, fast when its effect is roll change, labour intensity is low; Automatically the multi-roll straightening machine top roll of roll change system all is to adopt rotary oil cylinder locking with ram at present; Rotary oil cylinder is fixed on the ram, and an equipment needs 12 rotary oil cylinders.There is following defective:
1, the anglec of rotation of rotary locking cylinder is to lean on scrolling realization in the cannelure of steel ball on piston rod and cylinder body; The flexibility that the length of cannelure, angle, shape, steel ball slide etc. all influences the size of the piston rod anglec of rotation; Because influence factor is too many, so the difficulty of processing of this structure oil cylinder requires very high.
2 and rotary locking cylinder in use the pressure of the cleannes of oil and oil is all had relatively high expectations; There are foreign material will in-oil cylinder steel ball be blocked in the oil; Piston rod can not be rotated put in place, roll when dumb at steel ball, oil pressure is low can not to put the piston rod rotation in place.
When 3, adopting rotary oil cylinder locking top roll to be, be top roll system to be locked through the block of adorning on 12 rotary oil cylinder piston rods.When roller system locked, the piston of rotary oil cylinder was the back rectilinear motion that rotatablely moves earlier, through the block on the piston rod top roll system is strained; When roller system unclamped, the piston of rotary oil cylinder was to rotatablely move behind the first rectilinear motion, and block on the piston rod and roller system throws off then.Require the anglec of rotation of rotary oil cylinder very accurate here, and require good stability, reliability height; If piston rod half-twist on request, the block when top roll system throws off during roll change on the rotary oil cylinder piston rod will interfere phenomenon with roller system, gently then rotary oil cylinder is damaged, and is heavy then can to make whole top roll be to come off from ram equipment is smashed.Ram climbs away top roll when being in the roll change process, because the piston rod of indivedual rotary oil cylinders can not half-twist, it is the open slot on the base plate that the block on the piston rod will tangle top roll; Indivedual oil cylinders top roll system together risen, because of can't bear the deadweight that whole top roll is, phenomenons such as breaking can appear in piston rod, disengagement with ram; This moment, top roll system can be from pounding in the air to lower roll; Roller system and equipment are smashed, and entail dangers to life safety, so its security, reliability extreme difference.
Summary of the invention
For overcoming the deficiency of prior art, it is the piston cylinder forced locking device that goal of the invention of the present invention is to provide a kind of top roll, substitutes rotary oil cylinder locking through forced locking device, is effective locking of piston cylinder to realize top roll.
For realizing above-mentioned purpose; The present invention includes top working roll system, top roll is base plate and ram; It is characterized in that: the piston cylinder fixed support is fixed on the ram; Piston cylinder is connected with the piston cylinder fixed support, is equipped with in the piston cylinder that to be used for directly top roll be base plate and the ram auto lock and the top of unclamping.
The present invention compared with prior art has the following advantages:
1, the piston cylinder fixed support is fixed on the ram, can move up and down with ram, makes piston cylinder only need auto lock that very short stroke can guarantee top roll system and ram and unclamp.
2, because the purpose of piston cylinder is that top roll system is realized separating fast and locking with ram,, more faster with piston cylinder, more reliable, safer than rotating cylinder to improve the operating efficiency of roll change.
3, than former separation and locking mode, simple in structure, under the situation of identical coupling mechanism force, its volume is little more a lot of than original structure rotational lock oil cylinder.
4, piston cylinder piston rod when locking oil suction chamber is a rodless cavity, and oil suction chamber is the structure of rod chamber when the original structure locking cylinder is locked, and under the situation of identical cylinder diameter, oil cylinder coupling mechanism force of the present invention is 1.7 times of original structure.
Description of drawings
Accompanying drawing is invention structural representation sketch.
Specific embodiments
Shown in accompanying drawing; Top working roll is 6 to cooperate the rectification strip effect of playing with bottom working roll system; On the ram 8 of the straightener arrival end and the port of export, respectively adorn four piston cylinder fixed supports 1 with screw 2; Adorn a piston cylinder 5 with piston cylinder hold-down screw 4 on each piston cylinder fixed support 1, respectively adorn a top 3 on the piston rod of each piston cylinder 5, be used for directly with top roll be base plate 7 with ram 8 auto locks with unclamp.
During piston cylinder 5 oil-feeds, it is on the base plate 7 that top 3 can directly withstand on top roll, and making ram 8 and top roll is that base plate 7 is locked each other; When piston cylinder 5 is fuel-displaced, realize that ram 8 and top roll are unclamping each other of base plate 7.
