Abstract
The invention discloses a composite structure friction welding piston blank for a retarder. Currently, a piston blank for the retarder is produced via an integral die forging technology and is produced into a finished product via manufacturing technologies like mechanical processing and heat treating. In the forging technology, a parting line must be reserved, a large flash is generated on the head portion, and a large working allowance must be reserved for mechanical processing. All the parting line, the large flash and the large working allowance are required to be cut off during production, so that special workers and mechanical processing equipment are required, a large number of cutting tools are consumed, and the problems about low producing efficiency and delivery date prolongation are caused simultaneously. The composite structure friction welding piston blank for the retarder comprises a head portion (1), the head portion and an intermediate portion (2) are in friction welding connection, and the intermediate portion and a portion (3) are in friction welding connection. The composite structure friction welding piston blank for the retarder is used for piston blank.
Description
Technical field:
It is woollen with composite structure friction welding piston to the present invention relates to a kind of decelerating.
Background technique:
At present, decelerating adopts the mold integral Forging Technology to produce with piston blank always, and then carries out the manufacturing process such as machining, hotlist processing and be processed into finished product.This Forging Technology must leave paring line, and produces larger overlap at head, leaves very large machining allowance but also be necessary for machining.Need in process of production they are all excised, this just needs to arrange special personnel, machining equipment, and consumes a large amount of cutters, causes simultaneously the problems such as manufacturing efficiency is low, prolongation at delivery date.
Summary of the invention:
It is woollen with composite structure friction welding piston to the purpose of this invention is to provide a kind of decelerating.
Above-mentioned purpose realizes by following technological scheme:
A kind of decelerating is woollen with composite structure friction welding piston, and its composition comprises: head, described head and middle part friction welding, described middle part and the friction welding of bar section.
Described decelerating is woollen with composite structure friction welding piston, and the weld at described head and described middle part has overlap A, and described middle part and described bar section weld have overlap B.
Described decelerating is woollen with composite structure friction welding piston, and described overlap A, described overlap B are the eversion type overlap.
Beneficial effect:
1. the present invention can save material, and the head of piston, middle part and bar section adopt the suitable dimension bar of customization, needn't leave very large machining allowance as mold integral forges, thereby greatly save material consumption.
2. the present invention can reduce processing cost, the waste that has caused because excising the waste of equipment that its irregular overlap and paring line cause, cutter, personnel, management, also reduced the very large machining allowance of removing the mold integral rough forging when having reduced the processing rough forging.
3. the present invention can energy saving, adopts Friction welding technique to produce the spent energy of this woolen cloth, burns whole blank red and forges the energy consumption that occurs much smaller than the mold integral Forging Technology.
4. the present invention also owing to reduced the time waste that causes when processing rough forging, shortens the manufacture cycle because friction welding manufacturing efficiency is high greatly, improve throughput, shorten delivery date, promote the market competitiveness, improve Business Economic Benefit, also have very large social value.

Embodiment:
Embodiment 1:
A kind of decelerating is woollen with composite structure friction welding piston, and its composition comprises: head 1, described head and middle part 2 friction weldings, described middle part and 3 friction weldings of bar section.
Embodiment 2:
Woollen with composite structure friction welding piston according to the described decelerating of embodiment 1, the weld at described head and described middle part has overlap A, and described middle part and described bar section weld have overlap B.
Embodiment 3:
Woollen with composite structure friction welding piston according to embodiment's 1 described decelerating, described overlap A, described overlap B are the eversion type overlap.
Embodiment 4:
Above-mentioned decelerating is woollen with composite structure friction welding piston, and piston is decomposed into head, middle part and bar section three parts, and prepares separately each part by the bar of the suitable dimension that customizes respectively.Head and middle part are welded together in the friction welding mode, can produce eversion type overlap (seeing accompanying drawing 5, accompanying drawing 1) this moment at head and middle part junction point, again itself and bar section are welded together in the friction welding mode, can (see accompanying drawing 1 at middle part and the junction point generation eversion type overlap of bar section this moment, so just produced that to make as a whole piston woollen, head, the three sections bars in middle part and bar section formed respectively the piston woolen cloth 1,2,3(sees accompanying drawing 1) three places.Carry out again the subsequent handlings such as machining and hotlist processing until produce piston finished product.
Embodiment 5:
Above-mentioned decelerating is woollen with composite structure friction welding piston, piston is decomposed into head (seeing accompanying drawing 3), middle part (seeing accompanying drawing 4) and bar section (seeing accompanying drawing 5) three parts also prepares separately by bar respectively.Head and middle part and middle part and bar section are welded into an integral body in the friction welding mode respectively, carry out again the production of the subsequent handlings such as machining and hotlist processing.When producing by this technology, can carry out at the woollen head of piston and middle part and middle part the junction point generation eversion type overlap (seeing accompanying drawing 1) of friction welding with bar section, this is the main sign that is different from the production of alternate manner blank.
Adopt the decelerating piston of this explained hereafter, the consumption that not only greatly saves material is enhanced productivity, and reduce to produce waste, and Supply period shortened greatly.This technology has significant consumption reduction, puies forward the effect effect.
Embodiment 6:
Above-mentioned decelerating is woollen with composite structure friction welding piston, adopts composite structure, and integrally welded in the friction welding mode, and then carries out the manufacturing process such as machining, hotlist processing and be processed into finished product.The decelerating piston blank is (the seeing accompanying drawing 2) made with the technique of unitary mould forging molding before this.It is woollen to adopt friction-welding technique to produce the decelerating piston, consumption greatly not only saves material, enhance productivity, and the waste of the equipment that has caused because of its irregular overlap and paring line when having reduced the processing rough forging, cutter, personnel, management, and Supply period shortened greatly.This technology have significant consumption reduction, energy-conservation, put forward the effect effect.This technology can be used for now widely used plain edition decelerating (such as TDJ302 type, TDJK103 type, TDJT103 type, TDJT103 type, TDJDS101 type decelerating etc.), also can be used for high-load speed reducing support (such as TDJ2000 type, TDJT2000 type decelerating etc.).By the piston of this explained hereafter can dot connective type, the hump of the same normal use with former piston in marshaling yard entirely push up, full top, station track speed control system.
