Abstract
The utility model relates to an upper forging die for forging a ball head of a car thrusting rod. The upper forging die comprises an inner core, a body and a die cavity, wherein the inner core and the body are of a combined structure, the body is provided with a through hole, and the inner core is installed into the body through the through hole and penetrated into the die cavity. According to the technical scheme, the through hole is a trapezoid hole and comprises a lower circular hole and an upper circular hole, the inner diameter of the upper circular hole is greater than that of the lower circular hole, the inner core is divided into a working section, a matching section and a fixed section, the size of the matching section is matched with the lower circular hole, the size of the fixed section is matched with the upper circular hole, the inner core is installed into the body through the upper circular hole of the through hole, the working section of the inner core penetrates through the through hole to enter the die cavity, a liner plate is installed above the fixed section of the inner core, and the liner plate is connected with the body through a screw. By adopting the technical scheme, the upper forging die is simpler and more convenient to produce, the production efficiency is higher, the consistency of the size of the die cavity is high, convenience for refining the die cavity is realized, and the smoothness can be guaranteed.
Description
Technical field
The utility model relates to a kind of for forging the mould of auto parts and components, especially a kind of for forging the upper forging die of automotive track bar bulb.
Background technology
Ball-end parts is connected to form by annulus head and circular pin portion, head, between bar by compared with orthodrome transition, part head annulus wall is thinner, highly larger and relative round bar axis is asymmetric up and down, cause the annulus die cavity in the part of the upper die of this part forging die narrower, narrow die cavity needs electric pulse processing, and to mould, manufacture brings larger difficulty.And on traditional bulb, forging die adopts overall structure (seeing Fig. 1), inner core part at first with red-hot Metal Contact, and all the time height hit load and thermic load the two simultaneously pulsed load and environmental condition of unloading under work, very easily cause that pressure is collapsed, wearing and tearing, distortion and heat fatigue cracking; Forge end of a period process, because Web thickness attenuation, the temperature at forging head blind hole place declines, the larger pressure that inner core bears can be extruded to cavity bottom plane, cause outer shroud root place because of tension easy to crack; In addition, annular die cavity is narrower, and the exhaust of forging process die cavity has some setbacks, and easily causes forging part to be not fully filled.Therefore, mould service life is low, and product percent defective is high, has seriously restricted production efficiency, has increased production cost.
Utility model content
The technical problems to be solved in the utility model is to provide forging die on a kind of bulb of making simple, long service life, and the technical problem that the utility model further will solve is to provide a kind of die cavity exhaust and goes up forging die smoothly.
For solving first technical problem, on a kind of bulb provided by the utility model, forging die comprises inner core, body, die cavity, and inner core and body are fabricated structure, has a through hole on described body, and described inner core packs body into from through hole, and protrudes into die cavity.
The further technical scheme of the utility model is, described through hole is shoulder hole, comprise a lower circular hole and a upper circular hole, the internal diameter of upper circular hole is greater than the internal diameter of lower circular hole, described inner core is divided into active section, coordinates section and canned paragraph, wherein coordinate the size of section to match with lower circular hole, the size of canned paragraph matches with upper circular hole, described inner core circular hole from through hole packs body into, inner core active section protrudes into die cavity through through hole, backing plate is equipped with in the top of inner core canned paragraph, and described backing plate is connected with body by screw.
Adopt technique scheme, make the making of forging die more easy, knockdown structure can be carried out lathe in machining, can only adopt electric pulse processing to compare with whole mould, production efficiency is faster, and cavity dimension uniformity is high, die cavity refine is convenient, and bright and clean degree can be guaranteed.And the pressure bearing due to the inner core of fabricated structure is absorbed by backing plate, the probability of the outer shroud root cracking of cavity bottom plane reduces to zero, and mould service life can significantly improve.In addition, when inner core inefficacy rear mold die cavity, other place still can continue to be on active service, and now mould is reprocessed, and traditional overall structure can only synchronously be carried out everywhere, and combining structure of the present utility model only need reprocess or change inner core.Moreover inner core of the present utility model can adopt separately the slightly poor and excellent mold materials of other performance of toughness, thus make mold cavity everywhere service life reach unanimity.
The utility model further technical scheme is that the inner core of upper forging die and body contact position are matched in clearance, between described backing plate and inner core canned paragraph, outwards have air discharge duct.
Adopt technique scheme, when mould is in running order, by the air discharge duct on inner core and body fit clearance and backing plate, overflow residual gas, can fully guarantee being full of of forging, thereby significantly reduce product percent defective.

The specific embodiment
As shown in the figure: forging die on a kind of bulb, it comprises inner core 2, body 1, die cavity 3, inner core 2 and body 1 are fabricated structure, on described body 1, have a through hole 7, described through hole 7 is shoulder hole, comprise a lower circular hole 72 and a upper circular hole 71, the internal diameter of upper circular hole 71 is greater than the internal diameter of lower circular hole 72, described inner core 2 is divided into active section 23, coordinate section 22 and canned paragraph 21, wherein coordinate the size of section 22 to match with lower circular hole 72, the size of canned paragraph 21 matches with upper circular hole 71, described inner core 2 circular hole 71 from through hole 7 packs body into, inner core 2 active sections 23 protrude into die cavity 3 through through hole 7, backing plate 4 is equipped with in the top of inner core 2 canned paragraphs 21, described backing plate 4 is connected with body 1 by screw 5.Inner core 2 is matched in clearance with body 1 contact position, chooses suitable gap both to meet the discharge of residual gas, does not produce again longitudinal burr, and outwards have air discharge duct 6 between backing plate 4 and inner core 2 canned paragraphs 21.
