Abstract
The utility model discloses a die floats evenly sets up a plurality of outsides at the top surface edge of die and has an open -ended through -hole, the through -hole be parallel to each other, the opening sets up on the side of die, the opening width is less than the diameter of through -hole, sets up the steel ball in the through -hole, and both ends set up and make the outer stop device of the unable roll -off through -hole of steel ball about the through -hole. Stop device be end cover or nut. Through -hole perpendicular to die top surface. The diameter of steel ball is 6mm -6.04mm, the diameter of through -hole slightly is greater than the diameter of steel ball. Set up a 10 -12 through -hole on the die. The die top surface is circular or square. Compared with the prior art, the utility model, it becomes sliding friction for rolling friction, the degree of wear greatly reduced at die edge, and the accessible to set up through -hole and the steel ball of different diameters covert with the die central point time just to the life of die has been guaranteed.
Description
Technical field
The utility model relates to a kind of shaped device, specifically, is a kind of floating cavity die.
Background technology
When having the cross of blind hole or a T-shaped forging for forging lower end, the general ratio of height to diameter of the blind hole due to such part is all more than 2.0, and the technique therefore used is generally floating cavity die assistant formation.For floating cavity die a kind of motion back and forth in fact, adopt sliding friction more.Because in precision forging, the power between metal and metal can be larger.The technique of this classics in use, because when die is cast, center always there will be error, the offset loading force of forging molding often occurs that locking phenomenon appears in die and die trim ring, and the members that this phenomenon result in die is easy to breakage, and economic benefit reduces greatly.
Summary of the invention
Goal of the invention: the purpose of this utility model is to provide a kind of long service life, floating cavity die applied widely.
Technical scheme: the utility model comprises following technical scheme: a kind of floating cavity die, comprise die body, in the top edge of die body, the through hole of some outsides with opening is evenly set, described through hole is parallel to each other, described opening is arranged on the side of die, described A/F is less than the diameter of through hole, arranges steel ball in through hole, and the upper and lower two ends of through hole arrange and make steel ball cannot skid off stopping means outside through hole.
Described stopping means is end cap or nut.
Described through hole is perpendicular to die end face.
The diameter of described steel ball is 6mm-6.04mm, and the diameter of described through hole is slightly larger than the diameter of steel ball.
Described die is arranged 10-12 through hole.
Described die end face is circular or square.
Beneficial effect: the utility model compared with prior art, it becomes sliding friction is rolling friction, the degree of wear at die edge reduces greatly, and covert die central point is just returned of through hole and steel ball by arranging different-diameter, thus ensure that the service life of die.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Detailed description of the invention
Below in conjunction with Figure of description, the utility model is described in further detail:
The utility model relates to die during a kind of cold forging, it comprises a die body 1, die body can be columniform, also can be cuboid or square, in the center of die end face, be provided with the endoporus that push rod passes through, at the edge of die end face, the through hole 2 that some outsides are provided with opening is set, these through holes 2 are parallel each other, steel ball 3 is provided with inside through hole 2, the size of steel ball 3 is slightly less than the diameter of through hole 2, such guarantee steel ball rolls freely in through hole, the size of through hole 2 outer openings is also less than the diameter of through hole, like this after steel ball 3 loads, a part for steel ball 3 is given prominence to outside opening.
Because endoporus exists a lot of tolerances in manufacturer, generally beat within 0.04, there is again the gap 0.1-0.2 of die and die trim ring simultaneously, cause overall tolerance grade about 0.20, therefore, the through hole of different size is set according to actual conditions on die, coordinates the steel ball of different sizes supporting with it, so just can eliminate the concentric error that tolerance is brought.Specifically, the diameter of described described steel ball is 6mm-6.04mm, and die generally arranges 10-12 through hole.
At the two ends of through hole, be provided with stopping means, after loading stopping means, steel ball just can only slide in through-holes.In general stopping means adopts hex nut or end cap.
