Abstract
The invention discloses a kind of horizontal centrifugal casting method of hollow rollers, be applicable to the horizontal centrifugal casting production of hollow rollers.It is to utilize running gate system to support a fuse in the roller mould, and fuse can rotate with mould under the drive of fluid injection in casting process.After fluid injection was watered and expired, the roller internal cavities just solidified according to the shape of fuse, reaches the horizontal centrifugal casting purpose of hollow rollers with this.
Use this kind method can realize utilizing two or more material laminated pouring hollow rollers, improve the roller quality, reduce production costs, enhance productivity.
Description
The present invention relates to a kind of horizontal casting method for centrifugal, be exclusively used in horizontal centrifugal casting hollow rollers.Here the hollow rollers of indication is meant that the roller internal cavities is complex-shaped, and promptly internal diameter is inconsistent, and the part of convex-concave is arranged in the cavity, as shapes such as Fig. 1, Fig. 2, Fig. 3.
The material of making this rollers has plenty of unsaturated polyester resin, has plenty of non-ferrous metal, ferrous metal or alloy.No matter use what material, so long as use the casting manufacturing, at present all usefulness be to leave standstill casting.But leave standstill cast and often cause roller tissue looseness, defectives such as pore, shrinkage cavity, slag inclusion occur, make the product mechanical performance descend the percent defective height.And, leaving standstill cast and can't on same roller, use two or more material laminated pouring, this is to the serviceability that improves roller and reduce cost totally unfavorable.
Task of the present invention is to propose a kind of horizontal casting method for centrifugal, makes above hollow rollers can realize horizontal centrifugal casting production.
The present invention finishes as follows: produce one and the corresponding to fuse of roller internal cavities earlier, utilize the top of running gate system that fuse is supported in the mould then, fuse and mould are on the same axis, utilize positioner restriction running gate system in the position that mould shaft makes progress then, and then reach the axial location of restriction fuse in mould.Running gate system can realize the cast of fluid injection, plays the support and the positioning action of fuse simultaneously again.Fuse can rotate around the support of running gate system end.In casting process, in a single day fluid injection reaches the degree of touching the outer garden of fuse cylinder, and fuse is rotated with fluid injection.Cast finishes, and fluid injection can stop the rotation of horizontal centrifuge after solidifying, and at the appropriate time, the roller of cast is taken out from mould.
Concrete mode of the present invention, following drying cylinder with the cast paper machine is an example, is illustrated.Longitudinal sectional drawing as shown in Figure 4: mould (1) places on horizontal centrifugal the watering (2), and fuse (3) is supported in the mould (1) with one heart by both sides running gate system (4).The axial location of fuse (3) in mould (1) determined by positioner (5).Cover mould both sides end caps (6), urgent pin (7) just can be poured into a mould.During cast, starting centrifuge (2), mould (1) and then rotates, treat stability of rotation, when reaching certain rotating speed, fluid injection is poured in the running gate system (4), so fluid injection is promptly injected the mould (1) that rotates along the arrow direction through the bottom outlet or the side opening of running gate system (4), treat that fluid injection annotates to a certain degree, will drive fuse (3) and rotate with mould (1) and fluid injection together.Continue to pour into fluid injection, till the middle Kong Yuanzhou of fluid injection and end cap (6) is equal.Treat that the fluid injection in the mould (1) solidifies fully, can make horizontal centrifuge (2) stall, running gate system (4) is withdrawed from from mould (1) along guide rail (8), cross and from mould (1), to take out drying cylinder foundry goods (9) certain the time.
Claims (4)
1, by horizontal centrifuge (2), mould (1), end cap (6), pin (7), running gate system (4), guide rail (8) is formed the horizontal centrifugal casting method of implementing, and it is characterized in that:
Also support a rotary fuse (3) in a, the mould (1), fuse (3) and mould (1) coaxial line by running gate system (4).
B, running gate system positioner (5) have been determined the axial location of fuse (3) in mould (1).
2, according to the method for claim 1 regulation, the supporting way that running gate system (4) supports fuse (3) is that the conical surface or garden cylinder support.
3, according to the method for claim 1 regulation, in the running gate system (4) fluid injection will be below running gate system (4) or the side inject the gap of mould (1) and fuse (3).
4, all hollow rollers that directly make with method disclosed by the invention.
