Abstract
The utility model provides a compound tank grip -pad of manganese steel cladding titanium alloy, sets up the ear in grip -pad main part both sides including grip -pad main part and the symmetry that is equipped with the lightening hole, and its technical essential is: run through the lightening hole in the grip -pad main part and be equipped with pilot hole I, be equipped with respectively in the ear one with the pilot hole II of lightening hole syntropy, grip -pad outside -in is manganese steel metal level, titanium alloying metal layer in proper order. Fundamentally has solved that current grip -pad cold resistance is poor, with high costs, the loaded down with trivial details scheduling problem of preparation technology of preparation, and it has advantages such as with low costs, the excellent performance of preparation.
Description
Technical field
This utility model belongs to panzer creeper tread production field, and a kind of manganese steel cladding titanium alloy is combined tank creeper tread.
Background technology
The creeper tread of tank is typically manufactured by manganese steel, produces hardening thus high intensity and wear-resistant when foreign impacts, improves service life.But, it being susceptible to brittle fracture at low temperature psychro-environment, weight ratio is bigger.Round-the-clock and the design of lightness is difficult to solve the problems referred to above.
Utility model content
The purpose of this utility model is to provide a kind of manganese steel cladding titanium alloy and is combined tank creeper tread, fundamentally solves the problems such as existing creeper tread cold tolerance is poor, preparation cost high, preparation technology is loaded down with trivial details, and it has the advantages such as low, the function admirable of preparation cost.
For achieving the above object, this utility model provides following technical scheme: this manganese steel cladding titanium alloy is combined tank creeper tread, including being provided with the creeper tread main body of lightening hole and being symmetricly set on the ear of creeper tread main body both sides, it is characterized in that: run through lightening hole in described creeper tread main body and be provided with pilot hole I, be respectively equipped with in ear one with lightening hole pilot hole II in the same direction, creeper tread ecto-entad is followed successively by manganese steel metal level, titanium alloy metal level.
This utility model additionally provides a kind of manganese steel cladding titanium alloy and is combined the production method of tank creeper tread, is characterized in that, comprises the following steps:
Step 1) pierced billet manganese steel tubing, forges and rolls titanium alloy rod bar；
Step 2) process manganese steel internal surface of pipe and titanium alloy rod bar outer surface；
Step 3) is cut manganese steel tubing and titanium alloy rod bar and is penetrated in an interference fit in manganese steel tubing by titanium alloy rod bar；
Step 4) uses Q235 board making plug, soldering and sealing manganese steel tubing in vacuum welding equipment；
Step 5) hot-rolling mill vacuum rolling titanium alloy manganese steel compound bar billet produces compound square rod, rolling footpath contracting ratio >=50%；
Step 6) rolling square tube annealing, after 850 DEG C of insulation 1h, naturally cools to room temperature；
Step 7) saw cut blanking, die-forging forming, semi-finished product can be obtained after machining；
Step 8) uses plasma or local laser quenching, 500 DEG C ~ 650 DEG C overall tempering, is incubated 1 ~ 3h, and machining gets product again.
The beneficial effects of the utility model: use manganese steel cladding titanium alloy composite construction, change the performance of original bi-material, learn from other's strong points to offset one's weaknesses so that creeper tread performance is greatly improved.The result of the differential hardening processing method in place of contacting creeper tread with ground, all increases than simple manganese steel hardness and bulk strength.Remaining the shock resistance of manganese steel material, abrasion resistance properties, meanwhile, titanium alloy improves creeper tread cold tolerance, improves overall intensity, alleviates overall weight.Composite construction creeper tread obtains simple substance manganese steel or the higher properties of product of titanium alloy.The acquisition methods of composite construction is that Vacuum Heat rolls composite molding.Carry out subsequent mechanical processing after various stress is completely eliminated, complete creeper tread processing.It is practically free of Cutting Process step, reduces raw material loss and machining period is lost.

This manganese steel cladding titanium alloy is combined the production method of tank creeper tread, comprises the following steps:
Step 1) pierced billet manganese steel tubing, forges and rolls titanium alloy rod bar；
Step 2) process manganese steel internal surface of pipe and titanium alloy rod bar outer surface；
Step 3) is cut manganese steel tubing and titanium alloy rod bar and is penetrated in an interference fit by titanium alloy rod bar in manganese steel tubing, makees matrix, the manganese steel of surface recombination 5mm thickness, faying face metallurgical binding with titanium alloy.
Step 4) uses Q235 board making plug, soldering and sealing manganese steel tubing in vacuum welding equipment；
Step 5) hot-rolling mill vacuum rolling titanium alloy manganese steel compound bar billet produces compound square rod, rolling footpath contracting ratio >=50%；
Step 6) rolling square tube annealing, after 850 DEG C of insulation 1h, naturally cools to room temperature；
Step 7) saw cut blanking, die-forging forming, semi-finished product can be obtained after machining；
Step 8) contact surface location carries out local heat treatmet, reaches manganese steel quenching intensity requirement.Using plasma or local laser quenching, 500 DEG C ~ 650 DEG C overall tempering, be incubated 1 ~ 3h, machining gets product again.
