Abstract
The utility model relates to a drawing anvil for forging. A V-shaped structural groove is arranged at the middle part of the drawing anvil. The depth of the V-shaped structural groove is one third to one second of the thickness of the drawing anvil. A junction at the bottom is an arc-shaped structure. An isosceles-trapezoid-shaped structure is arranged in the center of the bottom of the drawing anvil. Compared with the prior art, since the axial flowing method is adopted, the utility model has the advantages that the drawing effect is improved, the rejection rate of forgings is effectively reduced, the difficulty that the center of the forgings is apt to get loose is solved, the application scope is wide, the manufacturing is easy and the disassembling and the assembling are convenient.
Description
Technical field
The utility model relates to a kind of pulling shape anvil, especially relates to a kind of forging processing with pulling out the shape anvil.
Background technology
Forging all kinds of pulling operations of hot-working is the most basic operational sequences commonly used.To small lot batch manufacture, at present the affected pulling operation of open die forging is generally all used on the counterpart anvil piece of lower plane and is carried out.When processing circular bar and hollow tubular product,, have a strong impact on pulling effect work efficiency because anvil piece material deformation when workpiece is subjected to upward pressure freely changes vertically and radially up and down.Particularly to the more difficult pulling of hollow cylindrical forged piece, also can cause sometimes axially to tear open and split and scrap.To high-alloy steel, high-temperature alloy material because material plasticity extreme difference, and during pulling always by 90 ° of upsets, the pulling of rectangular bloom side, radially the cross shearing force is big and cause centre burst and cracking radially, and the center is difficult for forging saturating, gives the raising work efficiency, guarantees that product quality brings difficulty.
Summary of the invention
The purpose of this utility model is exactly to provide a kind of scrappage of effective reduction forging, utilization property wide in order to overcome the defective that above-mentioned prior art exists, and the forging processing of easy accessibility is with pulling shape anvil.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of forging processing is with pulling out the shape anvil, it is characterized in that the v-shaped structure groove is offered at the middle part of this pulling shape anvil, the degree of depth of this v-shaped structure groove is 1/3～1/2 of pulling chopping block thickness, the junction, bottom is a convex structure, and the center, bottom of pulling shape anvil is provided with the structure of isosceles-trapezium-shaped.
Angle between two hypotenuses of described v-shaped structure groove is 90 °～110 °.
Be connected for circular-arc transition between the plane on the hypotenuse of described v-shaped structure groove and the shape anvil.
Compared with prior art, the utlity model has following advantage:
(1) because the anvil piece is made V-arrangement and can be limited the workpiece metal flow direction,, axial flow pulls out effect for improving;
(2) effectively reduce the scrappage of forging, forge in V-arrangement, the material of plasticity difference is not easy to crack, and can reduce the axial crack in the forging pulling process;
(3) because the V-arrangement effect makes forging force trend center, and it is saturating that workpiece centre is forged, solve the easily loose difficult problem in forging center;
(4) utilization property is wide, easy to manufacture, easy accessibility.
Description of drawings
Fig. 1 is a scheme of installation of the present utility model;
Fig. 2 is a vertical view of the present utility model.
1 is that pulling shape anvil, 2 is that workpiece, 3 is that tup, 5 is for forging and pressing pedestals for carving iron, 4 among the figure.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Embodiment
A kind of forging processing is with pulling out the shape anvil, its scheme of installation as shown in Figure 1, vertical view as shown in Figure 2, the v-shaped structure groove is offered at the middle part of this pulling shape anvil 1, the degree of depth of this v-shaped structure groove is 1/3～1/2 of pulling chopping block 1 thickness, the junction, bottom is a convex structure, and the center, bottom of pulling shape anvil 1 is provided with the structure of isosceles-trapezium-shaped.Angle between two hypotenuses of v-shaped structure groove is 90 °～110 °.Be connected for circular-arc transition between the plane on the hypotenuse of v-shaped structure groove and the shape anvil.
As shown in Figure 1, over against placement, the bottom of pulling shape anvil 1 connects tup 4 and forging and pressing pedestal 5 respectively, carves the side that iron 3 is located at isosceles trapezoidal structure with two pulling shape anvils 1, and workpiece 2 is located in the v-shaped structure groove of two pulling shape anvils 1.Because the protection of v-shaped structure groove containment, workpiece 2 metal when pressing down are done the axial flow variation and reduced Radial Flow, thereby strengthen the pulling effect and prevent that material from radially ftractureing, ability is forged at raising forging center.The bottom of v-shaped structure groove is made convex structure and is reserved enough thickness, and assurance is born forging force and is unlikely to cracking.With pole pull out material forging side will or pole forge to the degree of depth greater than the v-shaped structure groove, after the angle ejection is poured in the cylindrical forged piece punching into, be put in do in the v-shaped structure groove forging and pressing and axially pulling go up the iron amount and be not more than 1/4th wide pullings of anvil, the pulling operation is finished back rotation limit feeding and is finished the round as a ball of forging.Available V-shape anvil up and down or upward flat V-shape anvil down reach above purpose.
Claims (3)
1. one kind is forged processing with pulling out the shape anvil, it is characterized in that the v-shaped structure groove is offered at the middle part of this pulling shape anvil, the degree of depth of this v-shaped structure groove is 1/3～1/2 of pulling chopping block thickness, the junction, bottom is a convex structure, and the center, bottom of pulling shape anvil is provided with the structure of isosceles-trapezium-shaped.
2. a kind of forging processing according to claim 1 is characterized in that with pulling shape anvil the angle between two hypotenuses of described v-shaped structure groove is 90 °～110 °.
3. a kind of forging processing according to claim 1 is characterized in that with pulling shape anvil, is connected for circular-arc transition between the plane on the hypotenuse of described v-shaped structure groove and the shape anvil.
