Abstract
The utility model discloses a width adjusting transmission device of a plate blank crystallizer. The width adjusting transmission device comprises a worm and gear reducer. One end of a ball screw rod is placed inside the worm and gear reducer, and the other end of the ball screw rod is placed inside a sleeve, wherein a bearing group which is matched with the ball screw rod is arranged inside the sleeve. A split flange is connected with a sliding shaft, a ball screw nut is fixed between the split flange and the sliding shaft, the worm and gear reducer drives the ball screw rod to rotate, and the ball screw nut drives the sliding shaft to move along an axial line direction to achieve width adjusting and narrowness adjusting of a narrow side of the crystallizer. The width adjusting transmission device of the plate blank crystallizer has the advantages of being high in control precision, strong in self-locking capacity, compact in structure and convenient to maintain, has a function of adjusting the width of the crystallizer hot/cold online, and can be widely used in the plate blank crystallizer.
Description
Technical field
The utility model relates to a kind of plate slab crystallizer and transfer wide transmission device.
Background technology
Crystallizer transfers wide transmission device to be used for supporting the mould at narrow parts, the wide mode of accent commonly used has hydraulic pressure to transfer the wide dual mode of wide and mechanical accent, it is the axial displacement of constraint screw mandrel that machinery is transferred wide mode, rotation by screw mandrel makes nut move along axis direction and realizes moving of mould at narrow parts, thereby changes the width of crystallizer.Traditional machinery transfers wide mode often to adopt trapezoidal screw, and structure end play is larger, and the situation of " running cone " not only occurs in process of production easily, the great difficulty of also bringing to automation control.Traditional machinery is transferred under the wide mode, the connected mode of transmission device and mould at narrow parts mounting hole commonly used and axle, and the replacing of mould at narrow parts and maintenance are inconvenient.
The utility model content
The purpose of this utility model is to provide a kind of drift skate billet crystallizer of narrow limit tapering that can effectively prevent to transfer wide transmission device.
To achieve these goals, by the following technical solutions: a kind of plate slab crystallizer is transferred wide transmission device, it is characterized in that: described device comprises worm type of reduction gearing, one end of ball screw is arranged in worm type of reduction gearing, the other end is arranged in sleeve pipe, be provided with the bearing group that cooperates with ball screw in its middle sleeve, the dissection type flange is connected with slide-bar, and ball screw nut is fixed on dissection type flange and slide-bar between the two, worm type of reduction gearing drives ball screw and rotates, ball screw nut drives slide-bar and moves along axis direction together, realizes that the accent of mould at narrow is wide narrow with accent.
Adopt the worm type of reduction gearing of large number ratio, guaranteed that total has good self-locking property in the course of the work, can effectively prevent the drift of narrow limit tapering.Ball screw nut adopts the dissection type flange to be connected with slide-bar, is convenient to dismounting.
Described ball screw adopts shaft shoulder structure.
Described bearing group is comprised of a needle bearing and two thrust bearings, and two thrust bearings are positioned at the two ends of needle bearing, and the bearing group rotation is flexible and end-play is very little.
Described bearing group is fixed on the shaft shoulder of ball screw by a stop pad and two round nuts, can effectively prevent becoming flexible in the course of work.
Described slide-bar front end adopts the structure of hook to link to each other with the mould at narrow parts, is convenient to change and safeguard narrow wall part spare.
Be provided with protective sleeve between described sleeve pipe and the slide-bar, prevent entering of dust and water vapour.
The utlity model has the control accuracy height, self-lock ability is strong, compact conformation, characteristics easy to maintenance.Possess online cold/wide function of heat accent of crystallizer, can be widely used in the plate slab crystallizer.
Description of drawings
Fig. 1 is front view of the present utility model;
Fig. 2 is cutaway view of the present utility model.
Among the figure: 1-worm type of reduction gearing, 2-flange supporting cover, 3-round nut, 4-bearing group, 5-bearing block, 6-dissection type flange, 7-ball screw, 8-sleeve pipe, 9-slide-bar, 10-protective sleeve.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments:
As depicted in figs. 1 and 2, a kind of plate slab crystallizer is transferred wide transmission device, with boltsly between worm type of reduction gearing 1 and flange supporting cover 2, bearing block 5, the sleeve pipe 8 becomes an integral body, and links to each other with crystalliser by sleeve pipe 8, compact conformation is convenient to dismounting.
This plate slab crystallizer transfers wide actuator beairng group 4 to be comprised of a needle bearing and two thrust bearings, two thrust bearings are positioned at the two ends of needle bearing, bearing group 4 is fixed on the shaft shoulder of ball screw 7 by a stop pad and two round nuts 3, makes whole mechanism end play very little.Dissection type flange 6 and slide-bar 9 are connected by bolt, and ball screw nut is fixed between the two, are convenient to dismounting.Slide-bar 9 front ends adopt the hook form to link to each other with the mould at narrow parts, so that the replacing of mould at narrow parts and safeguard very conveniently is provided with protective sleeve 10 between sleeve pipe 8 and the slide-bar 9, prevent entering of dust and water vapour.
Claims (5)
