Abstract

The utility model discloses a split supporting wheel lower die which is characterized by comprising an upper split die and a lower split die which can be inlaid with each other, wherein a first supporting wheel die cavity and a lower split die cavity which is located below the first supporting wheel die cavity and allows the lower split die to be inlaid are formed in the upper split die; and a second supporting wheel die cavity is formed in the lower split die. The split supporting wheel lower die is convenient to assemble, and has the same function as the existing supporting wheel lower die; a die blank used for producing the split supporting wheel lower die is light in weight and convenient to forge; the machining allowance is greatly reduced compared with the existing die blank; the machining time is shorter; and the production efficiency of the die is improved greatly.

Description

Split type thrust wheel counterdie

Technical field

The utility model belongs to forging mold field, relates to split type thrust wheel counterdie.

Background technology

Forging is that one utilizes metal forming machinery to exert pressure to metal stock, make it produce plastic deformation to obtain the processing method with certain mechanical performance, definite shape and size forging, the strength member that load is high in plant equipment, condition of work is poor, except sheet material, section bar or the weldment of the better simply available rolling of shape, adopt Forging Technology processing to obtain more.

Thrust wheel is a kind of wheel coordinating with crawler belt in excavator or bull-dozer, its Main Function is the complete machine weight that is supporting engineering machinery, drive crawler belt along with wheel advances, in order to guarantee that thrust wheel has enough intensity, generally processes thrust wheel by the mode of finish forge.In thrust wheel Forging Technology, mould is indispensable important process equipment, and the quality of its performance directly has influence on the crudy of thrust wheel.

Existing thrust wheel counterdie as shown in Figure 1, in thrust wheel counterdie 10, be formed with thrust wheel lower mode cavity 11, producing this thrust wheel counterdie 10 need to process to obtain by the die blank 20 to as shown in Figure 2, but, the size of die blank 20 is large, and forging difficulty is high, and allowance is larger simultaneously, long processing time, has affected production efficiency greatly.

Utility model content

Main purpose of the present utility model is to provide split type thrust wheel counterdie, can greatly improve the production efficiency of mould.

The utility model adopts following technical scheme:

Split type thrust wheel counterdie, it is characterized in that: comprise and can mutually inlay the upper split pattern and the lower split pattern that close, in described upper split pattern, be formed with the first thrust wheel die cavity and the lower split die cavity that the described lower split pattern of confession that is positioned at described the first thrust wheel die cavity below is bumped into, in described lower split pattern, be formed with the second thrust wheel die cavity.

Concrete, the periphery edge, bottom of described lower split pattern and the cooperation of the bottom of described upper split pattern are formed with location division.

Concrete, described the first thrust wheel die cavity and described the second thrust wheel die cavity coordinate the lower mode cavity that forms described thrust wheel.

Concrete, in described lower split pattern, be formed with the chamber that ejects that is positioned at described the second thrust wheel die cavity below.

From above-mentioned to description of the present utility model, compared with prior art, split type thrust wheel counterdie of the present utility model is easy to assembly, there is the function identical with existing thrust wheel counterdie, and it is lightweight to produce this split type thrust wheel counterdie die blank used, forge conveniently, allowance reduces a lot with respect to existing die blank simultaneously, and process time is shorter, greatly improve the production efficiency of mould.

The specific embodiment

Below by the specific embodiment, the utility model will be further described.

Split type thrust wheel counterdie as shown in Figure 3 and Figure 4, comprise and can mutually inlay the upper split pattern 30 and the lower split pattern 40 that close, in upper split pattern 30, be formed with the first thrust wheel die cavity 31 and be positioned at the lower split die cavity 32 that the lower split pattern 40 of confession of the first thrust wheel die cavity 31 belows is bumped into, in lower split pattern 40, be formed with the second thrust wheel die cavity 41, the periphery edge, bottom of lower split pattern 40 and the cooperation of the bottom of upper split pattern 30 are formed with location division 50, described the first thrust wheel die cavity 31 and the second thrust wheel die cavity 41 coordinate the lower mode cavity that forms thrust wheel, in lower split pattern 40, be formed be positioned at the second thrust wheel die cavity 41 belows eject chamber 42.

The die blank of the split type thrust wheel counterdie of this specific embodiment as shown in Figure 5, comprise the upper Split mold blank 61 of split pattern 30 and the lower Split mold blank 62 of lower split pattern 40, compared with the die blank 20 of upper Split mold blank 61 and lower Split mold blank 62 and the existing thrust wheel counterdie 10 described in background technology, blank weight greatly reduces, forge more convenient, and allowance reduces a lot, has reduced process time simultaneously, has greatly improved the production efficiency of mould.

Above are only a specific embodiment of the present utility model, but design concept of the present utility model is not limited to this, allly utilizes this design to carry out the change of unsubstantiality to the utility model, all should belong to the behavior of invading the utility model protection domain.

Claims
