Abstract
The utility model relates to a fan-shaped supporting forging, fan-shaped supporting forging's both sides limit department respectively is equipped with the step that is less than fan-shaped plane to the draft inclination of step department is 0-0.5. The utility model discloses a fan-shaped supporting forging can directly use and need not reprocessing.
Description
Technical field
The utility model relates to a kind of supporting forging, particularly a kind of fan-shaped supporting forging of engineering machinery.
Background technique
In the at present domestic FMT,, all need carry out the design of pattern draft to forging for making things convenient for the forging depanning; To the pattern draft of steel forgings, design is general all spends to about 7 degree 5, when forging equipment is had last lower push rod; Can suitably be reduced to 3 and spend to 5 degree, the depanning when design of this pattern draft is just forged for ease and a kind of dressing of adding, the product that forges can not directly use; Need in course of working subsequently, remove above-mentioned dressing, be the waste on a kind of material.
The model utility content
The utility model problem to be solved provides a kind of fan-shaped supporting forging, overcomes the problems referred to above that exist in the existing technology.
A kind of fan-shaped supporting forging of the utility model, the dual-side place of said fan-shaped supporting forging respectively is provided with the step that is lower than fan-shaped plan, and the pattern draft at said step place is 0 °-0.5 °.
Said fan-shaped supporting forging of the utility model and steel plate welding, said two steps are the welded seam place.
Through above technological scheme; The fan-shaped supporting forging of the utility model adds step through the dual-side at fan-shaped supporting forging and reduces pattern draft, directly uses to need not reprocessing; And the directly welding at the step place when fan-shaped supporting forging and steel plate welding, make reinforcement of weld.
Description of drawings
Fig. 1 is the structural drawing of the fan-shaped supporting forging of the utility model.
Schematic representation when Fig. 2 is 0 ° for said step and counterdie mould pattern draft.
Embodiment
As shown in Figure 1, a kind of fan-shaped supporting forging of the utility model, the dual-side place of fan-shaped supporting forging 1 respectively is provided with the step 2,3 that is lower than fan-shaped plan, and the pattern draft at step place is 0 °-0.5 °.The utility model is provided with step at the dual-side place, and the pattern draft that makes this place is less than 0 °, and therefore this fan-shaped supporting forging can directly assemble use, need not reprocessing.
As shown in Figure 2, the pattern draft that step 3 and counterdie mould 4 are set at two step places is 0 °, and by descending lifting pin with the up jacking of fan-shaped support forging, realize the demoulding this moment when the demoulding.And pattern draft is that 0 ° fan-shaped support forging is easy to use, and can satisfy user's demand.
Fan-shaped supporting forging of the utility model and steel plate welding, two steps are the welded seam place, add two steps, have improved the practicability of fan-shaped supporting forging, are easy to the welding of fan-shaped supporting forging and steel plate, and make reinforcement of weld.
Claims (2)
1. a fan-shaped supporting forging is characterized in that, the dual-side place of said fan-shaped supporting forging (1) respectively is provided with the step (2,3) that is lower than fan-shaped plan, and the pattern draft at said step place is 0 °-0.5 °.
2. fan-shaped supporting forging according to claim 1 is characterized in that, said fan-shaped supporting forging (1) and steel plate welding, and said two steps (2,3) are the welded seam place.
