Description

Spun casting roll fill out core casting platform

Technical field

The utility model relates to field of metallurgical machine, is specifically related to a kind of device of model carried when core casting filled out by roll.

Background technology

Roll first forms a columnar skin after spun casting, and skin is the working lining in the future of roll.After completing outer field spun casting, outer cylinder need be erected, below cylinder, place under casing, on cylinder, place under casing, cast gate, then carry out filling out core casting, to form roller blank.Filling out in core casting cycle, the columnar outside of centrifugal casting, just as the cold mould of filling out core casting.Fill out core casting die to comprise by the cast gate be coaxially connected, emit the basic elements of character such as case, cold mould and under casing to form, molten steel fills up mould gradually from cast gate, completes casting work.

In order to make under casing maintenance level, using at present usually backing plate pad under casing, namely casting pit floor placing some pieces of circumferentially uniform backing plates watering, then under casing is hung on backing plate, by regulating backing plate, with horizon rule, under casing is levelling.There is the shortcomings such as levelling difficulty is large, number of operations is many, waste time and energy in the method.

In addition, in cold mould mould assembling process, cold mould generally there will be rocks, and under casing also can rock thereupon, and backing plate is often subjected to displacement then.Thus, under casing is difficult to keep level, emits case, cold mould and under casing by run-off the straight on the whole, and cause during casting core molten iron and punching occurs partially, roll thickness difference is larger.

Therefore, developing a kind of novel centrifugal roller casting platform is very necessary and urgent to those skilled in the art.

Utility model content

The utility model technical issues that need to address are to provide a kind of novel centrifugal roller casting platform.

In order to solve the problem, the utility model provides following technical scheme:

A kind of centrifugal roller casting platform, comprise base, base upper surface is provided with one or more groove group, and each groove group is made up of the groove that 3-8 circumferentially distributes; Chock is placed with in groove.

Improvement of the present utility model is, is provided with reinforcement below wherein said base.The setting of reinforcement improves the quality of casting platform, maintains the intensity of casting platform, prevents the generation of the situations such as distortion, fracture.

Further improvement of the utility model is, the side of wherein said base is provided with hangs handle.Hang and under casing can be placed in casting melt pit by design easily, plateau levels can be sling and put into melt pit, also vertically can sling and put into melt pit.

Further improvement of the utility model is, wherein said each groove group is made up of 8 grooves.

Further improvement of the utility model is, wherein said base upper surface is provided with 2 groove groups.The groove of each groove group is circularly and evenly distributed.The design of double enhances the steady of casting platform and horizontal hold facility.

Further improvement of the utility model is, the bottom surface of wherein said chock is horizontal plane, and upper support face is inclined-plane, and chock afterbody is provided with projection upwards, the outer surface of described projection and the plane perpendicular of chock.When needing to regulate under casing level, chock is placed in groove, knocks chock afterbody with hammer etc.The convex-shaped design of chock has further facilitated finely tunes under casing level.

In sum, owing to have employed technique scheme, the utility model achieves following technological progress:

1, reduce the labour intensity of roll casting work, improve operating efficiency.During prior art use backing plate, under casing horizontal adjustment needs about 10 minutes, and utilizes the utility model, even if need adjustment under casing level, generally also only need can complete for about 3 minutes, operating efficiency promotes more than 70%.

Cold mould when 2, alleviating mould assembling is rocked, and improves the horizontal hold facility of under casing.Through actual production checking repeatedly, after using the utility model, during cold mould mould assembling, shaking degree obviously alleviates.After core has been cast, again measure under casing level, almost unchanged, the horizontal hold facility of under casing significantly improves;

3, reduce roll thickness difference, roll thickness difference qualification rate improves more than 30%.

Detailed description of the invention

Detailed description of the invention is only and further explains and describes the utility model, should not be interpreted as any restriction of the present utility model.

Below in conjunction with embodiment, the utility model is further elaborated:

Centrifugal roller casting platform as Figure 1-3, comprises base 1 and chock 6, and base 1 upper surface is provided with a groove group 2, and groove group 2 is made up of 8 grooves be circularly and evenly distributed 3; A chock 6 is placed in each groove 3; The tip of chock 6 is towards the center of groove group 2.Combination is when filling out core casting die, and in the circle that the groove group 2 that under casing is placed on platform surrounds, the edge of under casing is positioned at above groove 3, then successively by cold mould, emit case, cast gate is placed under casing.Base 1 lower surface is provided with reinforcement 4; Base 1 side is provided with hangs 5.

During use, as shown in Figure 4, under casing 7 is placed on base 1, if need the level adjusting under casing 7, chock 6 is placed under casing 7 times corresponding grooves 3, knocks with hammer.For the ease of adjusting the level of under casing, the bottom surface of chock 6 can be set to horizontal plane, and the upper support face of chock 6 can be set to inclined-plane, and chock 6 afterbody is provided with projection upwards, the outer surface of described projection and the plane perpendicular of chock 6.

Fig. 5-6 respectively illustrates the utility model with 3 and 4 grooves 3.

Fig. 7 shows the utility model that base 1 is provided with 2 groove groups.The groove 3 of each groove group 2 all can be circularly and evenly distributed.
