Abstract
The utility model provides a guide fixing device which is characterized in that the guide fixing device comprises two square head lead screws and a nut, the thread of one square head lead screw is left-hand, and the thread of the other square head lead screw is right-end; internal screws are arranged at both ends of the nut, one end of the internal screw is right-hand thread, and the other end of the internal screw is left-hand thread; and the internal screws are matched with two square head lead screws. With the adoption of the guide fixing device, the nut is rotated to adjust the length of the device, so that the guide is prevented from deviating from the rolling line during steel rolling, therefore, the stable function of the guide is ensured, and the size accuracy and production efficiency of the product can be improved.
Description
Technical field
The utility model relates to a kind of guide and guard fixture.
Background technology
In the online bar production process, thick, middle milling train misplaces guide and guard and pass because clam member loosening phenomenon in guide and guard lower end often appears in the impact of rolled piece, causes that finished size is overproof to be declared uselessly, or produces steel scrap midway, both wastes energy, and increases cost again.
In practical operation, for preventing to misplace about guide and guard, to fix with some wooden units in the guide and guard left and right sides, wooden unit length is fixed, and in when falling the pass, need the sawing Len req to fix, and is very inconvenient.
Summary of the invention
In order to overcome above-mentioned deficiency, the utility model provides a kind of guide and guard fixture, and this device length can be regulated, and can effectively prevent the dislocation of guide and guard and pass, has guaranteed the function-stable of guide and guard, has improved dimensional accuracy of products and production efficiency, the rate of reducing the number of rejects and seconds.
The utility model adopts following technical scheme: a kind of guide and guard fixture, it is characterized in that: comprise two square toes screw mandrels and nut, a square toes wire rod thread is left-handed, another part square toes wire rod thread is dextrorotation, the nut two ends are furnished with internal thread, one end is a right-handed thread, and the other end is a left hand thread, with two supporting uses of square toes screw mandrel.
Described nut is a hex nut.
Make positive left-hand thread fit screw rod, screw, two square toes screw mandrels cooperate with hex nut, the rotation hex nut with two screw mandrel distance adjustment to the shortest position, roll line is aimed in guide and guard, behind the fastening guide and guard pressing plate, place 1-3 fixture, reverse rotation hex nut according to the space in the guide and guard both sides, with two screw mandrels apart from increasing, till guide and guard are fixed.
The guide and guard fixture that the utility model provides, the rotation hex nut, can regulate the length of this device, solved the shortcoming of using the wooden unit equal length not regulate, after using this device, guide and guard depart from roll line in the time of can effectively preventing steel rolling, have both guaranteed the function-stable of guide and guard, have improved dimensional accuracy of products and production efficiency again.
Below in conjunction with drawings and Examples the utility model is described further.
Below in conjunction with drawings and Examples the utility model is described further.
Description of drawings:
Fig. 1 is the structure chart of guide and guard fixture.
1 is square toes among the figure, and 2 is screw mandrel, and 3 is nut, and 4 is screw mandrel.
The specific embodiment:
Embodiment 1:
The guide and guard fixture preparation method that the utility model provides is: processing square toes screw mandrel, and the square toes length of side is 110mm, and thickness is 25mm, and screw mandrel is long to be 80mm, the M64 screw thread, a wire rod thread is dextrorotation, another part wire rod thread is left-handed.Hex nut and two supporting uses of square toes screw mandrel, the length of hex nut is 150mm, and hex nut side diagonal angle length is 85mm, and two ends are furnished with internal thread, and an end is a left hand thread, and the other end is a right-handed thread, and left hand thread, right-handed thread length are respectively 85mm.
By positive left-hand thread combination, hex nut in the middle of the rotation can be regulated this instrument length, reaches the purpose of fastening guide and guard.In practical operation, can set the length of hex nut as required.
Taiyuan Iron and Steel Co. wire rolling plants pipe production line is since this device on probation on May 1st, 2010, reduced midway 63 tons in waste product and finished product waste product, and 78 hours fault times of adjustment of having reduced guide and guard effectively are for enterprise has created considerable benefit.
