Abstract
The adapting device of a kind of cold mould and end cap, comprise centrifugal cold mould, end cap, pin-and-hole, alignment pin, end cap projection, cold mould groove, at the port of centrifugal cold mould, end cap is installed, within one week in centrifugal cold mould port radial direction, be provided with pin-and-hole, be provided with conical dowel pin in pin-and-hole, alignment pin is by spacing for the end cap port at centrifugal cold mould; Be provided with cold mould groove at centrifugal cold mould port and end cap contact plane place, be provided with end cap projection at end cap and centrifugal cold mould port contact plane place, cold mould groove and the protruding matched in clearance of end cap.The beneficial effects of the utility model are: the adapting device of a kind of cold mould and end cap, effectively ensure that the fastness coordinated between cold mould with end cap, prevent in the process of centrifugal casting, molten iron outflow " runout ", improve the security in centrifugally cast composite roll production process, effectively ensure that the product quality of centrifugal roller, improve product percent of pass.
Description
Technical field
The utility model relates to the Fixture Design field of centrifugal roller casting in Special Processes of Metal Castings, particularly relates to the adapting device of a kind of centrifugal roller cold mould and end cap.
Background technology
Cold mould is the mould of centrifugally cast composite roll, is provided with end cap in two ports of cold mould, and the Main Function of end cap is exactly in the process of centrifugal casting, prevents molten iron from flowing out.In the prior art, what the contact surface that cold mould coordinates with end cap adopted is plane contact, and as shown in Figure 3, the drawback of existence is: 1) in centrifugal rotation, and because of the effect of centrifugal force, the relative cold mould of end cap is easily slided, thus end cap is loosened; 2) if the contact plane that coordinates with end cap of cold mould is uneven, the phenomenon that molten iron oozes out will be produced.Not only cannot ensure the qualification rate of product, but also serious potential safety hazard can be brought to production.
Summary of the invention
The utility model provides the adapting device of a kind of cold mould and end cap, and the end face that centrifugal cold mould contacts with end cap processes an annular recess, and the plane that end cap contacts with centrifugal cold mould processes an annular projection, makes protruding and groove matched in clearance.This structure effectively ensure that the fastness coordinated between cold mould with end cap, prevent in the process of centrifugal casting, molten iron outflow " runout ", improves the security in centrifugally cast composite roll production process, effectively ensure that the product quality of centrifugal roller, improve product percent of pass.
For achieving the above object, the utility model realizes by the following technical solutions:
The adapting device of a kind of cold mould and end cap, comprise centrifugal cold mould, end cap, pin-and-hole, alignment pin, end cap projection, cold mould groove, at the port of centrifugal cold mould, end cap is installed, within one week in centrifugal cold mould port radial direction, be provided with pin-and-hole, be provided with conical dowel pin in pin-and-hole, alignment pin is by spacing for the end cap port at centrifugal cold mould; Be provided with cold mould groove at centrifugal cold mould port and end cap contact plane place, be provided with end cap projection at end cap and centrifugal cold mould port contact plane place, cold mould groove and the protruding matched in clearance of end cap.
Compared with prior art, the beneficial effects of the utility model are:
An adapting device for cold mould and end cap, the end face that centrifugal cold mould contacts with end cap processes an annular recess, and the plane that end cap contacts with centrifugal cold mould processes an annular projection, makes protruding and groove matched in clearance.This structure effectively ensure that the fastness coordinated between cold mould with end cap, prevent in the process of centrifugal casting, molten iron outflow " runout ", improves the security in centrifugally cast composite roll production process, effectively ensure that the product quality of centrifugal roller, improve product percent of pass.
Accompanying drawing explanation
Fig. 1 is the structural representation of the adapting device of a kind of cold mould of the utility model and end cap.
Fig. 2 is the partial enlarged drawing of A point in Fig. 1.
Fig. 3 is the schematic diagram of cold mould and end cap fit system in prior art.
In figure: 1. centrifugal cold mould .2. end cap .3. end cap protruding .4. cold mould groove .5. pin-and-hole .6. alignment pin.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is further illustrated:
As shown in Figure 1-2, the adapting device of a kind of cold mould and end cap, comprise centrifugal cold mould 1, end cap 2, pin-and-hole 5, alignment pin 6, end cap projection 3, cold mould groove 4, at the port of centrifugal cold mould 1, end cap 2 is installed, within one week, pin-and-hole 5 is provided with in centrifugal cold mould 1 port radial direction, be provided with conical dowel pin 6 in pin-and-hole 5, alignment pin 6 is by spacing for end cap 2 port at centrifugal cold mould 1; Be provided with cold mould groove 4 at centrifugal cold mould 1 port and end cap 2 contact plane place, be provided with end cap projection 3 at end cap 2 with centrifugal cold mould 1 port contact plane place, cold mould groove 43 matched in clearance protruding with end cap.
Because centrifugal cold mould 1 and the contact end face of end cap 2 are a ring surface, therefore cold mould groove 4 is annular recess on cold mould end face, and cold mould groove 4 is trapezoid cross section.
End cap projection 3 is the annular protrusions matched with cold mould groove 4 position, and the cross section of end cap projection 3 is similarly trapezoid cross section.
The utility model is the technique improvement done under the prerequisite not changing original agent structure and performance, after enforcement, on the basis not increasing cost and operation easier, improve the security of production process, be conducive to the quality improving roll product, decrease the output of waste product, improve production efficiency.
