In the method, three-dimensional and hierarchical design is adopted, the designed cylinders have larger diameters and the overall size of the equipment is smaller, thus the large tube and bar straightening machines have reasonable structures, and the designed cylinders have beautiful appearances, are more convenient and reliable to use and are suitable for the large diameter multi-cross roll tube and bar straightening machines.
Description
Technical field
The present invention relates to the straightener technical field, especially be suitable for large-sized multiple-skew roller pipe, a kind of large-sized multiple-skew roller flattening machine balance of bar aligning, the distribution method of locking cylinder.
Background technology
At present, the continuous increase along with China's all trades and professions use pipe, bar specification requires metallurgical equipment to develop towards maximization, intelligentized direction.In pipe bar production enterprise, the cross roll straightening process is the effective method of pipe, WIRE FINISHING LINE.The counter lock locking oil cylinder of middle-size and small-size straightener is designed to an oil cylinder; be about to locking cylinder and balancing cylinder and be designed to one; be placed on the upper spider; be generally two oil cylinder symmetric arrangement; be positioned at the outside of protection oil cylinder; an oil cylinder is realized two kinds of functions; frequently adjust the pressure of oil cylinder according to need of work; hydraulic control is complicated and unreliable, and the piston stroke of existence locking balancing cylinder can be according to the size design of aligning specification limit, and often piston stroke is very long; processing time consuming is taken material; complex process, difficulty of processing is big, the very complicated shortcoming (as Fig. 1) of locking link.Therefore but large-scale straightener straightening force is bigger, protects oil cylinder and the locking cylinder diameter also can be very big.If also continue to use original design arrangement, can't satisfy the performance need of device fabrication.Because the straightening force of big specification pipe, bar is very big, the locking cylinder diameter increases thereupon, and straightener protection cylinder diameter also can be very big; will cause the straightener overall structure very huge like this, and the increase of aligning specification limit make the stroke of balancing cylinder very big; the equipment heaviness, and not attractive in appearance.
Summary of the invention
For overcoming the deficiencies in the prior art, the invention provides the distribution method of a kind of large-sized multiple-skew roller flattening machine balance, locking cylinder.Can solve because the problem that maximization brought of equipment is fit to large diameter pipe bar multi-cross roll straightening machine and uses, in the equipment operation is adjusted, simplified operation sequence greatly, convenient to use, dependable performance can be applicable in the large-sized multiple-skew roller flattening machine industry.
For realizing aforesaid goal of the invention, the present invention adopts technical scheme as described below:
The distribution method of described a kind of large-sized multiple-skew roller flattening machine balance, locking cylinder, its step is as follows:
1. adopting balancing cylinder and locking cylinder to split technology, is on the position of locking cylinder that two functions is different and balancing cylinder four symmetries being separately positioned on slide, forms three-dimensional the layout, and function is independent, and in the equipment operation is adjusted, directly simple;
2. locking cylinder is placed in the slide, and locking cylinder is according to the flywheel moment of calculating, setting pressure and piston diameter; When adjusting roll gap big or small, locking cylinder does not need change, only when adjusting the corner of roller, changes, and function is independent, and is convenient to operation.
3. compensating cylinder is arranged on the lower steel plate between slide and the upper spider; Be used for weight such as roller arrangement and rotating disk on the balance, the gap of eliminating elevating screw makes the roll gap of adjustment more accurate;
4. piston links to each other with holder on the slide, is provided with the protection oil cylinder above the upper spider, is used for weight such as roller arrangement and rotating disk on the balance, eliminates the effect in leading screw gap, and is convenient to make and installs and maintenance; According to weight such as last roller arrangement that calculates and rotating disk, setting pressure and piston diameter; According to the size of putting into of aligning specification limit, set the size of stroke;
5. balancing cylinder, locking cylinder design in the slide periphery, and be in a symmetrical arrangement.
The distribution method of described a kind of large-sized multiple-skew roller flattening machine balance, locking cylinder, locking cylinder are adjusted the size of stroke roll gap, are that the nut by threaded and two ends connects cylinder body, piston, slide and rotating disk; Behind the hydraulic oil that pours certain pressure in the oil pocket, piston rises, and the nut that drives threaded and two ends rises, and this moment, rotating disk and slide compressed, and played the purpose of locking; When adjusting the angle of roller, slide and rotating disk need be unclamped, at this time, and system decompression, piston returns, and nut, threaded and rotating disk descend, and obtain the purpose that slide and rotating disk unclamp.
The distribution method of described a kind of large-sized multiple-skew roller flattening machine balance, locking cylinder, the locking cylinder diameter can be designed to be applicable to the diameter of large-scale pipe, bar, make roller and pipe bar that good contact wire can be arranged, locking cylinder has bigger locking torque, overcome the flywheel moment that in the process of aligning, produces, the roller corner that is fixed makes roller and pipe bar that good contact wire can be arranged; And the less stroke design of locking cylinder: as long as slide and rotating disk are unclamped, can make the oil cylinder contour length very short, conserve space.
The distribution method of described a kind of large-sized multiple-skew roller flattening machine balance, locking cylinder, balancing cylinder are according to the load-bearing weight of calculating, and adjust pressure, in the process of whole aligning, no matter align which kind of specification, do not need change, described cylinder diameter can design less, but the stroke design is generally bigger.
Because adopt aforesaid technical scheme, the present invention has superiority as described below:
The distribution method of a kind of large-sized multiple-skew roller flattening machine balance, locking cylinder adopts novel locking cylinder and balancing cylinder to split technology, be with the design of the oil cylinder of two difference in functionalitys on the position of four symmetries of slide, function is independent.A design protection oil cylinder above the upper spider.Be applicable to the development and Design of large-scale pipe, bar straightener.This method adopts the design of chpn time, makes the more reasonable structure of large-scale pipe, bar straightener, and the design cylinder diameter is bigger, and the equipment overall dimensions is less, good looking appearance, and use more convenient reliably, be fit to large diameter pipe bar multi-cross roll straightening machine and use.In the equipment operation is adjusted, simplified operation sequence greatly, convenient to use, dependable performance can be applicable in the large-sized multiple-skew roller flattening machine industry.
