Abstract
The utility model discloses an upper floating support protection device of a casting mould tube. The traditional centrifugal casting machine drives the mould tube to rotate through a driving wheel, and the mould tube is supported at four points through four riding wheels (including a driving riding wheel). Due to the deviation of the geometrical dimension of the mould tube and the nonuniformity of the mass distribution of liquid steel in the mould tube in the casting process, the mould tube is easy to generate circular runout in the operation process, and seriously, the mould tube can separate from the four supporting points to generate a serious production accident to bring heavy economic losses to production and equipment. The utility model provides the upper floating support protection device of the casting mould tube, which is characterized in that by the elasticity of a compression spring, an upper floating roller is pressed on a groove of the outer wall of the mould tube to reduce the degree of freedom of the spatial move of the mould tube and prevent the circular runout. The protection device is convenient to use, has high safety and ensures the quality of a centrifugal casting product and the safety of workers.
Description
Technical field
The utility model relates to the moving protective device that supports of a kind of casting type tube come-up and belongs 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 the inner molten steel Mass Distribution of type tube in the deviation of type tube physical dimension and the casting cycle, easily cause type tube that circular runout takes place 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 takes place 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, does not almost have any effect to radially beating.Shortcomings such as type tube is easily beated so used centrifugal casting machine exists, poor stability.
Summary of the invention
The utility model proposes and a kind ofly can overcome above-mentioned defective, the control type barrel dliameter is gone up to float and is supported protective device to what beat.The moving protective device that supports of a kind of casting type tube come-up, it is characterized in that: the roller that upward floats is connected on the support by spring, place type tube directly over, its width and material are consistent with carrying roller.Float on a kind of centrifugal casting type tube and support protective device; mainly be to become with compression spring set, it is characterized in that: rely on the elastic force of compression spring, will go up the roller that floats and be pressed on the type tube outer wall groove by last unsteady roller, support; reduce the free degree that move in the type tube space, prevent circular runout.When type tube rotated, if abnormal conditions take place, going up floats supported the effect that protective device also can play protection equipment and operating personnel's production safety.
For achieving the above object, the utility model proposes the support protective device that floats on a kind of centrifugal casting type tube.According to practical working situation, designed special unsteady supporting form.This protective device adopts the compression spring to connect and goes up float roller and support, and directly acts on the groove of type tube outer wall by last unsteady roller.In order to prevent that unsteady roller from tangentially moving when type tube rotates, this protective device adopts support bar and hinges pair roller to fix.Therefore; the utility model proposes floats supports the design and use method of protective device; make the novel support protective device that floats of going up normally to move, thereby reached the control type barrel dliameter, guarantee centrifugal casting product quality and staff's purpose of safety to beating.
Description of drawings
Fig. 1 supports the protective device schematic diagram for floating on the centrifugal casting type tube.
The specific embodiment
Referring to accompanying drawing 1, be provided with the roller 30 that floats directly over the type tube 20, be provided with compression spring 40 above the roller, the upper end of compression 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 last unsteady roller 30, and an end is connected with hinge 50 on the support 70.
The operation of supporting protective device of floating on the design of moving roller to floating and the centrifugal casting type tube is below analyzed:
The design of unsteady roller on 1
Going up the roller that floats and be connected on the support by spring, is the core component of whole protecting device.Its design width and material go up the roller that floats and directly act on the type tube groove, so will be consistent with carrying roller.Because compression spring elastic force that provides and vertical the acting on the type tube of gravity that last unsteady roller provides are caused wearing and tearing for avoiding excessive compression to type tube and carrying roller, can not be excessive so go up the radius of the roller that floats, should not surpass half of carrying roller radius.
Float on 2 and support the operation of protective device
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 to float roller along the rolling of 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, earlier elastic force is adjusted to minimum during installation, comes the telescopic spring amount according to the size of the required compression of last unsteady roller during use.Can once more the spring compression be transferred to minimum when stopping using.Balance during for the operation of maintenance centrifugal casting machine is all installed the support protective device that floats in support roller position, type tube rear and front end.During spun casting, type tube turns round under the restriction of two groups of support protective devices that float, and effectively reduces circular runout.
Float to support protective device on the utility model and have the safety coefficient height, advantage such as easy to use, be the control type barrel dliameter to beating, guarantee a kind of invention of centrifugal casting product quality and staff's safety to have promotional value.
