Description

Leaf spring hot extrude ear frock

Technical field

The utility model belongs to leaf springs of car hanger processing technique field, is specifically related to a kind of leaf spring hot extrude ear frock.

Background technology

Leaf springs of car hanger width refers to the width of main assemblage of spring hanger part in prescribed limit, has two relevant parameters---length and width.Hanger width tolerance band requires in 0.22mm left and right, and hanger width coordinates with automobile hanger, belongs to matched in clearance, the too small installation difficulty in gap, and excesssive gap can make leaf spring swing, and produces noise, affects whole vehicle stability.Hanger processing length matches with the fitting limit of automobile hanger, too short assembling difficulty, long meeting causes processing difficulties, expense increases, affect leaf spring intensity, therefore leaf spring technological process is classified hanger manufacturing procedure one of as key procedure, and hanger width is also listed in one of leaf spring finished product final inspection project.

Traditional mill ear technique generally adopts mill earphone to carry out, mill earphone grinding speed guarantees by the oil cylinder speed that regulates lengthwise movement, the clamping position of the moving adjustment stroke switch of grinding length armrest and reed guarantees, polishing width is artificial feeding emery wheel, by the distance between two emery wheels, guarantee, manual operation has very large randomness, and dimensional accuracy is difficult to guarantee; Mill ear easily grinds burning reed, affects leaf spring performance; In production process, must specialize in this operation by three people of class Three, human resources consumption is large; Mill otoconia is taken turns easy explosion injure people, thing, the emery wheel spittle operator's eyes of easily burning; Emery wheel loss is large, and expense is high, and average every day is with four; Maintenance of equipment expense is high, and average every monthly 3000 yuan, and equipment failure rate is high, average every two days primary faults; Equipment cost is high, and a Daepori continuous grinding earphone price is just 5,60,000 yuan of left and right.

Utility model content

For overcoming the deficiency in above-mentioned technology, the purpose of this utility model is: a kind of leaf spring hot extrude ear frock is provided, and time saving and energy saving, save production cost.

The utility model for the technical scheme that its technical problem of solution adopts is:

Described leaf spring hot extrude ear frock, comprise cope match-plate pattern, lower bolster, upper die body and lower mold body, cope match-plate pattern and lower bolster are rectangular slab, upper die body and lower mold body are cylindrical structure, and lower mold body bottom surface is connected with lower bolster end face, and upper die body end face is connected with cope match-plate pattern bottom surface, on the two sides of cope match-plate pattern and lower bolster, corresponding position is respectively equipped with U-lag, lower mold body top is provided with V-block, and V-block is fixed on lower bolster end face, and cope match-plate pattern end face is provided with die shank.

The utility model is arranged on general 100kN gap-framepress and uses, and preferably, described upper die body bottom periphery and lower mold body end face periphery are chamfering structure, can prevent from, in the process of punch press extruding hanger, reed is squeezed to wound; Described V-block is provided with base, and base is provided with slotted hole, and V-block is fixed on lower bolster end face by slotted hole and bolt, can regulate by slotted hole and bolt the front and back position of V-block, meets different demands of squeezing ear length degree; The diameter of described upper die body and lower mold body is 150mm, is applicable to the hanger of all sizes on the market.

Operation principle is:

Before the utility model is used, on the U-lag and the T-shaped work top that is bolted to 100KN gap-framepress of lower bolster by its side, cope match-plate pattern is connected with crank press slide block mechanism with T-shaped bolt by the U-lag of die shank, cope match-plate pattern side; During use, reed is placed in lower mold body, the hanger of reed is clamped, is fixed by V-block, upper die body moves down under the effect of slide block, contact, push with hanger, the waste heat that utilizes grasswort operation to technological requirement width and length, should guarantee that reed temperature is not less than 700 degrees Celsius by hanger hot extrusion in extrusion process, reed heating-up temperature is very micro-on the impact of width, ignores.

Gap-framepress stroke can regulate and lock according to the developed width of required hanger, and dimensionally stable, is not affected by human factors, and the width tolerance band machine Accuracy that is only stressed, within statistics shows to can be controlled in 0.20mm; Squeeze ear length degree and guarantee that by the front and back position of adjusting V-block dimensionally stable is not affected by human factors; Forcing press extrusion process is improved effect to workpiece perpendicularity, and the squareness tolerance occurring in grasswort process has corrective action through squeezing after ear, and tolerance is reduced, and to the depth of parallelism without any harmful effect; Squeeze ear process and can make hanger aperture slightly diminish, available grasswort mandrel compensates in advance.

Compared with prior art, the utlity model has following beneficial effect:

The utility model is arranged on the enterprising enforcement of general 100KN initiation pressure machine and uses, gap-framepress slider-crank mechanism is rigidity, thereby the motion of slide block is enforceable, the position that slide block moves to bottom dead centre be adjustable and can lock constant, this structure energy stable extrusion quality, it has open type fuselage, being operated in three directions opens wide, loading, unloading Mould operation is all more convenient, can complete a slice leaf spring hot extrude ear technique 5 seconds, and efficiency is high.

Empirical tests, the utility model often completes 150 automobile hot extrude ear techniques can save 2, emery wheel, and leaf spring performance, without any harmful effect, is reduced expenses to 500 yuan, and by monthly 10000 calculating, ten thousand yuan of the 3-4 of economizing on the use of funds by the moon, year save 410,000 yuan; Mill ear operation is saved 3 people, saves every year 120000 yuan of labour costs; Only 1000 yuan of left and right of leaf spring hot extrude ear frock expense, life cycle can reach 2 years; Avoid the potential safety hazard because using mill earphone emery wheel explosion and the emery wheel spittle to hurt sb.'s feelings, ensured workman's personal safety; Strict guarantee assembly width and mill ear length degree, within error remains on 0.2mm; Save the energy, avoided security incident, within 1 year, can produce approximately 20,000 yuan of indirect economic effects.
