Abstract
The utility model relates to a processing mold, in particular to a pressure mold for processing cylindrical workpieces. The above mold is characterized in that it comprises an outer mold and an inner mold. The outer mold is a sleeve and the inner surface thereof is a taper. The inner mold comprises a plurality of conical wedges circumferencially equispaced. The inner surfaces of the conical wedges are in anastomosis with the surfaces of the workpieces, while the outer surfaces of the conical wedges are in anastomosis with the inner surfaces of the outer mold. Wedge bond between the outer mold and the inner mold is adopted. By adopting vertical pressurization instead of horizontal pressurization, higher output pressure is obtained under lower input pressure, which effectively lowers the load requirement of pressurized equipments. The conical wedges circumferencially equispaced as the inner mold for loading components basically enable the sections of workpieces to be round. The movement distance of the pressurized outer mold increases substantially, thereby improving the processing precision thereof.
Description
Technical field
The utility model relates to processing mold, is specifically related to a kind of pressurizing mold that is used for processing column shape workpiece.
Background technology
At present, general pressurizing mold is by inner mold pressure to be acted on the work piece (body to be extruded), make work piece produce plastic deformation, its subject matter is: 1, because will produce plastic deformation, so it is very big that this tonnage requires, the tonnage that is extruded part of Φ 30X70mm for example directly puts on pressure when being extruded part, and its pressure is greater than 100 tons.2, common pressurizing mold is two compositions up and down, and this has just determined the work piece of finishing will be the form of fracture of sub-elliptical.Because plastic deformation produces on compression aspect, when having only two moulds, make work piece realize uniform plastic deformation not too easily.3, owing to require plastic deformation normally very little in the process, have only several millimeters usually, therefore adopt existing processing mold machining accuracy to be difficult to control.
Summary of the invention
The purpose of this utility model is to provide a kind of load requirement that can effectively reduce pressurized equipment, and can make the complete pressurizing mold that is used for processing column shape workpiece that is shaped to circle of workpiece section.
Realize the technical scheme of the utility model purpose: a kind of pressurizing mold that is used for processing column shape workpiece, comprise outer mold and inner mold, described outer mold is that inner surface is the sleeve of taper, described inner mold comprises circumferentially uniform some taper voussoirs, the inner surface of taper voussoir and work piece surface coincide, and the outer surface of taper voussoir and the inner surface of outer mold coincide.
Aforesaid a kind of pressurizing mold that is used for processing column shape workpiece, inner module comprise circumferentially 8 uniform taper voussoirs.
Effect of the present utility model is: adopt wedge shape to combine between outer mold and the inner mold, will vertically pressurize changes the level pressurization into, has obtained big output pressure with little input pressure, effectively reduces the load requirement to pressurized equipment.Inner mold as loading component is the some taper voussoirs that circumferentially distribute, and the section that can make workpiece is circular substantially.Because the movement travel of pressurization outer mold extends greatly, makes machining accuracy to improve.
Description of drawings
Fig. 1 is a kind of sectional drawing that is used for the pressurizing mold of processing column shape workpiece provided by the utility model;
Fig. 2 is a kind of profile that is used for the pressurizing mold of processing column shape workpiece provided by the utility model.
Among the figure: 1. outer mold; 2. inner mold; 3. taper voussoir; 4. work piece.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As depicted in figs. 1 and 2, a kind of pressurizing mold that is used for processing column shape workpiece comprises outer mold 1 and inner mold 2.Outer mold is that inner surface is the sleeve of taper, and inner mold 2 is made up of circumferential 8 uniform taper voussoirs 3, and the number of taper voussoir 3 can be selected as the case may be, can be by 6,10 or 12 etc.
The concrete course of work of the present utility model is as follows: earlier work piece 4 is put into the outer mold 1 inside center position that inner surface is taper, then 8 taper voussoirs 3 are inserted simultaneously in the cavity that outer mold 1 and workpiece 4 surround, make 8 taper voussoirs 3 circumferentially uniform.At last with the horizontal movement restriction of the outer right part of taper voussoir 3, as add a block.As shown in Figure 2, when needs carry out pressurized operation, on outer mold 1, apply active force to the right, it is moved right.Because the outer end motion to the right of inner mold 2 is limited, owing to the effect on inclined-plane between the interior outer mold, inner mold will apply vertical pressure to the work piece surface again.
The utility model adopts circumferentially that 8 uniform taper voussoirs directly pressurize to workpiece, makes the section of the workpiece after the pressurization be essentially circular, satisfies the processing needs.
The principle of this device is the inclined plane principle in the physics, and it makes imposed load and machining accuracy all be enhanced ctan (a) doubly.Wherein a is the angle between inner mold 1 and 3 inclined-planes of outer mold and the horizontal plane, and it is to be formed by the inclined-plane between interior outer mold.Physical relationship such as following two formula:
F
Go into=F
Go out* ctan (a);
D
Go into=D
Go out* ctan (a).
Wherein, F
Go intoBe the input load that is applied to outer mold, F
Go outIt is the service load that acts on the work piece; D
Go intoBe the actual outer mold horizontal displacement that is applied on the outer mold, D
Go outIt is the pressurization displacement up or down that inner mold is applied to work piece.As angle a is 5 when spending, and ctan (a)=11.43 at this moment, adds compressive load and has been enhanced about 11 times, and machining accuracy also is enhanced and has made an appointment with 11 times.
Obviously, those skilled in the art can carry out various changes and modification to the utility model and not break away from spirit and scope of the present utility model.If these are revised and modification belongs within the scope of the utility model claim and equivalent technologies thereof, then the utility model also is intended to comprise these changes and modification interior.
