Abstract
The invention discloses a roller spacing online dynamic adjustment device, belongs to the technical field of skew rolling and relates to a two-roller seamless tube rolling mill. The roller spacing online dynamic adjustment device solves the problems that the accuracy of the longitudinal wall thickness of a steel tube is low, and loss is serious because the head and the tail of the steel tube are cut after the steel tube passes through a stretch reducing mill l. The roller spacing online dynamic adjustment device comprises an oil cylinder fixed to a base. The oil cylinder is a two-level double-acting cylinder and is composed of an oil cylinder rod I, an oil cylinder rod II and an oil cylinder barrel, wherein the oil cylinder is fixed to the base, a first-level oil cylinder body of the oil cylinder is a double-rod fine adjustment oil cylinder, a second-level oil cylinder body of the oil cylinder is a double-rod quickly-opening oil cylinder, the oil cylinder rod II is a cylinder barrel of the second-level oil cylinder body at the same time, and a limiting block is fixed to the tail of the oil cylinder rod II; a adjusting cushion block is further arranged between the oil cylinder barrel and the limiting block. The roller spacing online dynamic adjustment device conducts mechanical limiting, simplifies a hydraulic and electrical control system and is easy and convenient to operate and low in cost.
Description
Technical field
The invention belongs to oblique milling technical field, relate to two roller slitless tube mills, be specifically related to a kind of roller for two-roller skew-rolling slitless tube mill apart from online dynamic adjusting device.
Technical background
Hot rolled seamless steel tube production technology is the technology by operations such as heating of pipe blank, perforation, mill milling, sizing, alignings, solid pipe billet being processed into seamless steel pipe, tradition two roller slitless tube mills do not have roll spacing on-line tuning function, in the process of rolled steel tube, there will be the phenomenon that steel pipe head, tail wall thickness are overproof, cause the losses of crop, back-end crop to increase the problem directly affecting the lumber recovery of steel pipe.
In order to solve the problems referred to above that prior art exists, the present invention have developed a kind of roller apart from online dynamic adjusting device.
Summary of the invention
The present invention is low at longitudinal wall thickness accuracy after opening and subtracting machine in order to solve steel pipe, and crop end loses serious problem, and provides a kind of roller apart from online dynamic adjusting device.
The present invention is achieved by the following technical solutions:
A kind of roller is apart from online dynamic adjusting device, and comprise the oil cylinder be fixed on base, described oil cylinder is secondary two-way cylinder, is made up of cylinder rod I, cylinder rod II, cylinder tube; Wherein oil cylinder is fixed on base, and the one-level oil cylinder of oil cylinder is two rod fine setting oil cylinders, and two-level oil cylinder is that two rod opens oil cylinder soon, and cylinder rod II is the cylinder barrel of two-level oil cylinder simultaneously, and its afterbody is fixed with limited block simultaneously; Wherein also be placed with adjustment cushion block between cylinder tube and limited block.
Further, the afterbody perforate of described cylinder rod I, inbuilt displacement sensor, can Accurate Determining fine setting and the displacement opened soon.
Described oil cylinder is fixed on base by interior six square bolts.
During use, can the present invention be directly installed on roll, also can be placed on frame, coordinate with balancing cylinder online dynamic conditioning mill rolls apart from value.When being installed on roll-box, the cylinder masthead of oil cylinder is on frame, and as shown in Figure 3,4, the balancing cylinder that roll-box is fixed in frame pulls, and makes to drive oil cylinder bar soon and contacts gapless with frame mechanical planarization.
The operation principle of one-level oil cylinder of the present invention is: oil cylinder is fixed on base by interior six square bolts, limited block is secured by bolts on cylinder rod II rear end face, cylinder tube rear end face, end face and the limited block end face of the back cavity extension bar of oil cylinder are machined surface, when cylinder rod II does not stretch out, after limited block is in place, its end face and cylinder tube rear end face distance are definite value H and can survey, adjustment cushion block is installed between cylinder tube rear end face and limited block front end face, its thickness is h, difference s between H and h is the stroke that oil cylinder stretches out, s value is by mechanical position assurance, s value is reliable and adjust pad h value accurate adjustment by changing, by changing the specifications vary h value of adjustment cushion block, different oil cylinder stroke s values can be obtained, namely accurately control the overhang of oil cylinder, the accurate control of steel tube head wall thickness sharpening amount can be realized, its inbuilt displacement sensor detects the amount of feeding of oil cylinder, steel tube head wall thickness sharpening amount can be read in control room, convenient debugging and production process monitoring, two-level oil cylinder's operation principle: two-level oil cylinder is for open oil cylinder soon, action is full stroke action, duty is that oil cylinder back cavity enters pressure oil and all stretches out state at ordinary times, steel pipe rolling is apart from oil cylinder back cavity pressure release ante-chamber oil-feed during afterbody 50-100mm, under roll-force and front cavity pressure effect, cylinder rod I is return fast and steel pipe is passed through, and prevents tail card accident from occurring, second act as two-level oil cylinder and has overload protection function, drives cylinder action roll soon open when roll-force exceedes setting value, and steel pipe stops rolling, and proterctive equipment is not impaired.
The present invention adopts mechanical position limitation, simplifies hydraulic pressure and electric control system, easy and simple to handle, cost is low.
