The molding drum (20), the up-floating roller (30), the pressure spring (40) and the hinge (50) are arranged in the holder (70). The up-floating roller (30) is connected to the holder (70) through the pressure spring (40) and arranged right above the molding drum (20). The up-floating roller (30) acts on a groove of the molding drum (20), and is fixed by the aid of the support bar (10) and the movable hinge (50). By the arrangement, an up-floating support protection device can operate normally so as to control the molding drum to bounce radially, and centrifugal casting product quality and personnel security are guaranteed.
Description
Technical field
The present invention relates to a kind of casting type tube upper floating support protection device and belong to metallurgy, machinery, electric power, centrifugal casting field, mine.
Background technology
Centrifugal casting machine is to drive type tube by driving wheel to rotate, and type tube is realized four-point supporting by four support rollers (comprise and drive support roller).Because the inhomogeneities of type tube internal steel liquid Mass Distribution in the deviation of type tube physical dimension and the casting cycle, easily cause type tube that circular runout occurs in operation process, when especially the diameter large-scale type tube that surpasses 1m runs up, beating can be more obvious, type tube can break away from four strong points and serious production accident occurs when serious, cause centrifugal casting to scrap even cause type tube to scrap, give and produce and equipment causes heavy economic losses.Centrifugal casting machine type tube protective device at present commonly used is a simple crossbeam, flies out to prevent type tube, to radially beating almost without any effect.The shortcomings such as type tube is easily beated so used centrifugal casting machine exists, poor stability.
Summary of the invention
The present invention proposes a kind ofly can overcome defects, and the control type barrel dliameter is to the upper floating support protection device of beating.
The present invention is achieved through the following technical solutions goal of the invention:
A kind of casting type tube upper floating support protection device; comprise support bar, type tube, upper unsteady roller, Compress Spring, hinges, regulation and control nut, support; described type tube, upper unsteady roller, Compress Spring, hinge all are arranged in the described support; the upper roller that floats is connected on the support by Compress Spring; place type tube directly over; the upper roller that floats directly acts in the groove of type tube, adopts the fixing upper roller that floats of support bar and hinges.
The elastic force of the Compress Spring among the present invention can carry out free adjustment by the regulation and control nut.
Support described in the present invention is fixed by regulation and control nut or hinges.
Beneficial effect:
The present invention proposes the design and use method of upper floating support protection device, so that novel upper floating support protection device can normally move, thereby has reached the control type barrel dliameter to beating, and guarantees the purpose of centrifugal casting product quality and staff's safety.
Description of drawings
Fig. 1 is centrifugal casting moulded barrel upper floating support protection device schematic diagram.
The specific embodiment
A kind of casting type tube upper floating support protection device; comprise support bar 10, type tube 20, upper unsteady roller 30, Compress Spring 40, hinges 50, regulation and control nut 60, support 70; wherein type tube 20, upper unsteady roller 30, Compress Spring 40, hinge 50 all are arranged in the support 70; the upper roller 30 that floats is connected on the support 70 by Compress Spring 40; place type tube 20 directly over; the upper roller 30 that floats directly acts in the groove of type tube 20, adopts support bar 10 and the hinges 50 fixing upper rollers 30 that float.The elastic force of the Compress Spring 40 among the present invention can carry out free adjustment by regulation and control nut 60.Support 70 among the present invention is fixing by regulation and control nut 60 or hinges 50.
Upper unsteady roller 30 among the present invention directly acts on the groove of type tube 20, reduce the free degree that move in type tube 20 spaces, thereby prevent type tube 20 circular runouts, upper unsteady roller 30 among the present invention is connected on the support 70 by Compress Spring 40, place type tube 20 directly over, its width and material are consistent with carrying roller.Adopt support bar 10 and the hinges 50 fixing upper rollers 30 that float, prevent that unsteady roller 30 from moving along the tangential direction that type tube 20 rotates, medium-height trestle 70 of the present invention is fixed by screw or hinge, can freely dismantle, and is convenient for changing type tube.
The present invention relies on the elastic force of Compress Spring 40, and upper unsteady roller 30 is pressed on type tube 20 unit with grooves in outer walls, reduces the free degree that move in type tube 20 spaces, prevents circular runout.When type tube 20 rotated, if the abnormal situation, upper floating support protection device also can play the effect of protection equipment and operating personnel's production safety.
Tangentially mobile when type tube rotates in order to prevent upper unsteady roller, this protective device adopts support bar and hinges pair roller to fix.Therefore, the present invention proposes the design and use method of upper floating support protection device, so that novel upper floating support protection device can normally move, thereby has reached the control type barrel dliameter to beating, and guarantees the purpose of centrifugal casting product quality and staff's safety.
Referring to accompanying drawing 1, be provided with unsteady roller 30 directly over the type tube 20, be provided with Compress Spring 40 above the roller, the upper end of Compress Spring is set as the bolt form, be fixed on the support 70 by regulation and control nut 60, can change the size of elastic force by adjusting nut, support bar 10 1 ends link to each other with upper unsteady roller 30, and an end is connected with hinge 50 on the support 70.
The below analyzes the float design of moving roller and the operation of centrifugal casting moulded barrel upper floating support protection device:
The design of unsteady roller on 1
The upper roller that floats is connected on the support by spring, is the core component of whole protective device.The upper roller that floats directly acts on the type tube groove, so its design width and material will be consistent with carrying roller.Because the Compress Spring elastic force that provides and vertical the acting on the type tube of gravity that upper unsteady roller provides are caused wearing and tearing for avoiding excessive compression to type tube and carrying roller, so the upper radius that floats roller can not be excessive, should not surpass half of carrying roller radius.
The operation of 2 upper floating support protection devices
After the type tube of centrifugal casting machine places, mounting and fixing bracket, unsteady support roller is positioned at directly over the type tube.For preventing that upper unsteady roller from rolling along the type tube tangential direction, this protective device adopts support bar and hinges pair roller to fix.Adjusting nut can change the size of spring force, first elastic force is adjusted to minimum during installation, with the time come the telescopic spring amount according to the size of the required compression of upper unsteady roller.Can again spring-compressed be transferred to minimum when stopping using.Balance during for the operation of maintenance centrifugal casting machine is all installed upper floating support protection device in support roller position, type tube rear and front end.During spun casting, type tube turns round under the restriction of two groups of float support protective devices, effectively reduces circular runout.
The advantages such as it is high that upper floating support protection device of the present invention has safety coefficient, easy to use are the control type barrel dliameters to beating, and guarantee a kind of invention of centrifugal casting product quality and staff's safety, have promotional value.
