Abstract
The utility model provides a lifting lug series forge piece extrusion blank-making mold which comprises an upper mold and a lower mold. A cavity matched with a lifting lug series forge piece in appearance is formed in the lower mold, the upper mold is provided with a punch pin matched with the lifting lug series forge piece in appearance, the combined portion of the cavity and the punch pin is positioned through a square key; the end portion of the punch pin is provided with a port matched with the inner portion of the lifting lug connecting portion. A lifting lug series forge piece blank is vertically placed, blank materials are made to move from top to bottom through the matching action of the punch pin and the cavity, the cavity can be filled with the blank materials in the process of forging and pressing, and according to use of arc positioning, the position of the blanking materials is limited, so that the requirement for reasonable distribution of the size and the materials of each portion of a part is satisfied and one side of the cavity of the lower mold is opened, and therefore a forge piece can be taken out conveniently. Abrasion of the bridge portion of a finished forging mold is eliminated, the expense of the tool is reduced, the use rate of the materials is improved by over 80%, the appearance quality of the forge piece is remarkably improved, and the production efficiency is improved by 10%.
Description
Technical field
The utility model relates to the forging of auto parts and components, particularly hanger series forging extrusion blanking mold.
Background technology
Hanger series material utilization rate is only 69% at present, mainly to adopt tradition to keep flat finish forging technique after the direct blocking of pattern, its Preform Die structure is to utilize the middle cleaver divider sub-material of upper/lower die die cavity to make the position moulding of forging prong, in forming process, die wear is fast, the life-span is low, forging surface quality is poor, and a large amount of materials is wasted at prong position.Later stage also need spend a large amount of time and fund on maintenance die.
Summary of the invention
The utility model, in order to reduce costs, reduce overlap, improves the utilization rate of material, the special hanger series forging extrusion blanking mold that proposes.
The technical solution of the utility model is for this reason, and hanger series forging extrusion blanking mold, comprises upper and lower mould, it is characterized in that: at counterdie, be provided with and the identical die cavity of hanger series forging profile; Patrix is provided with and the identical drift of hanger series forging profile; The end of drift is provided with the inner identical prong in hanger junction.
Improvement to such scheme is: both sides, counterdie die cavity top are provided with the circular arc location of blank; Counterdie die cavity one side is provided with cavity side opening.
Beneficial effect:
The utility model is laterally placed hanger series forging blank, changed traditional pattern that keeps flat, the mating reaction of drift and die cavity is moved blank from the top down, in forging and stamping process, blank can be full of die cavity, the use of circular arc location makes the limited location of blank, thereby meets the size at each position of parts and the reasonable distribution of material, and counterdie die cavity one side opening is convenient to take out forging, the product side direction that moulding is received is taken out, take out convenient.
Can obviously improve the wearing and tearing of finish-forging die bridge portion, reduce the expense of frock, stock utilization is risen to more than 80%, forging presentation quality also will be significantly improved.
Production efficiency improves 10%, with hanger series, produces 250000 per year, makes to reduce to 1.4%, approximately 70,000 yuan of cost savings because of the percent defective that fork distortion causes; Reduce and to reprocess and 50,000 yuan of labour costs; Save 2.11 yuan/part of material cost; Add up to reduce costs approximately 64.8 ten thousand yuan the whole year.
Accompanying drawing explanation
Fig. 1 is that master of the present utility model looks cutaway view.
Fig. 2 is that cutaway view is looked on a left side of the present utility model.
Fig. 3 is that hanger master looks schematic diagram.
Fig. 4 is that schematic diagram is looked on a hanger left side.
In figure, 1 is patrix, the 2nd, and counterdie, the 3rd, die cavity, the 4th, drift, the 5th, prong, the 6th, circular arc location, the 7, the 8th, hanger ear, the 9, the 10th, hanger arm, the 11st, hanger head, the 12nd, cavity side opening.
The specific embodiment
The utility model as shown in Figure 1, 2.
Hanger series forging extrusion blanking mold, comprises upper and lower mould 1,2, is provided with and the identical die cavity 3 of hanger series forging profile in counterdie 2; Patrix 1 has and the identical drift 4 of hanger series forging profile, and the junction of die cavity 3 and drift 4 is provided with circular arc location 6, and counterdie 2 die cavity 3 one sides are provided with cavity side opening 12; The prong 5 of drift 4 ends.
In use, utilize the blank of putting of circular arc location 6, blank utilizes prong 5 fixing descending, under the acting in conjunction of die cavity 3 and drift 4, be first 11 moulding of hanger head, then continue descendingly, the mobile generation hanger arm 9,10 of blank, finally forms hanger ear 7,8, also the reasonable distribution that has guaranteed material when guaranteeing product design size, cavity side opening 12 is convenient to take out forging.
Claims (2)
1. hanger series forging extrusion blanking mold, comprises upper and lower mould, it is characterized in that: in counterdie, be provided with and the identical die cavity of hanger series forging profile; Patrix is provided with and the identical drift of hanger series forging profile; The end of drift is provided with the inner identical prong in hanger junction.
2. hanger series forging extrusion blanking mold according to claim 1, is characterized in that: both sides, counterdie die cavity top are provided with the circular arc location of blank; Counterdie die cavity one side is provided with cavity side opening.
