Abstract

The utility model relates to a device for producing a lining ring made of a steel band by fast heating, rolled forming and quenching, which is composed of a feeding device, a heating device, and a quenching device. The steel band passes through the device and can process the required lining rings with different sizes; the quality of the products can be ensured. The device has the advantages of simple structure, convenient operation, and one person for per shift, and the device can produce the lining rings of the steel bands up to 534 pieces; the device can be used for processing the quenching rounding of the thin lining ring of a steel band assembly with complicated pitch and multiple hole sites.

Description

Equipment for producing lining ring made of steel band by fast heating, rolled forming and quenching

A kind of steel band grommet is rolled into the garden quenching apparatus with rapid heating and belongs to piston ring producing apparatus technical field.

Piston ring comprises scraping ring and grommet, in the prior art, the grommet manufacturing is earlier the steel band cold-extruded to be pressed into U-shaped to become the cross section, be wrapped in then on the quenching threaded bar and heat-treat, need Equipment for Heating Processing to have in year: preheating oven, oil removing groove, salt bath furnace, quenching tank, Cleaning Line etc., also need be equipped with a large amount of frock clamps, accessory and chemical industry auxiliary material (as acid, alkali, salt etc.) in addition, this just makes that manufacturing process's time of steel band grommet is long, and occupation area of equipment reaches 80m ²More than, energy consumption is many, contaminate environment, and labor strength is big, and per tour needs 4 people, per hour can only produce 46 steel band grommets, and therefore, existing manufacturing steel band grommet equipment can not satisfy the demand of market to piston ring.

The purpose of this utility model is: at the problems referred to above, provide a kind of simple in structure, easy to operate, and can make steel band grommet rapid heating be rolled into the equipment that quenches in the garden.

Concrete structure of the present utility model can be illustrated in conjunction with the accompanying drawings.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is a B-B sectional view among Fig. 1.

Know among the people figure that the utility model is made up of pay-off I, heater II, quenching unit III, speed and the speed in pay-off I of steel band A in the quenching unit III is synchronous, constant to guarantee steel band A pitch, temperature in the thermocouple 8 control heater II, whole equipment operation state of button 9 controls.

The pay-off I by feed table 1, Worm Wheel System decelerator 3 and be contained in two pairs of pinch rollers 4 on its casing face, and the belt pulley 2 of transferring power form; The heater II is made up of base 6 and the heating tube 7 that is placed on the heating furnace 5 on the base 6 and be contained in the heating furnace 5, heating furnace 5 adopts high temperature nickel chromium triangle electric-heating-wire-heating stove, heating tube 7 is selected OCr25A15 type heat-resistant tube or is selected the high quartz glass tube, and its specification is φ 32 * 3.5 * 1100mm.

The quenching device III by geartransmission speed reduction unit 11 and be contained in a rod for stiring materials 10 on its casing face, sizing wheel 12, cam 22, recessed 23, the sleeve 24 that connects material, and lower header 16, upper water box 17, variable valve 13 etc. form, sizing wheel 12 can move on the casing face of speed reduction unit 11, thereby obtains the grommet of different radii.Upper water box 17 is connected with lower header 16 by pipe 15, and upper water box 17 also connects a pipe 14 in addition and passes through variable valve 13 to quenching place, and the solution after the quenching flows back to lower header 16 and forms the recycle systems.Two transmission shafts 19,20 in the speed reduction unit 11 all stretch out outside the casing, an axle end of 20 is equipped with recessedly takes turns 23 and be provided with two respectively in two supportings place and can make axle 20 compressing members that move up and down 21, (in order to wearing steel band again), one end of axle 19 is equipped with and recessed 23 cams that are complementary 22 and the sleeve 24 that connects material of taking turns, the sprocket wheel 18 of the other end dress transferring power.

The working process of this equipment is: the U steel band of model A that is contained on the feeding table 1 is driven synchronously by worm and gear gearing speed-reducer 3 and geartransmission speed reduction unit 11 speed with 46mm/ second, enter the heating tube 7 in the process furnace 5, the U steel band of model A that from heating tube 7, comes out by cam 22, recessed take turns 23 the location after, be quenched to quenched martensite immediately, U steel band of model A has formed a garden arc continuously under the roll extrusion of convex-concave wheel simultaneously, a rod for stiring materials 10 dials steel band A from cam 22, makes it to rotate from the sleeve 24 that connects material.The flow of quenching solution is by variable valve 13 controls.

Outstanding effect of the present utility model is: (1) reduces heat treatment process equipment, frock clamp, chemical industry auxiliary material, reduces heat treatment step, and boost productivity (2), per tour only needs one people operation, per hour can produce 534 steel band grommets, (3) reduce working area, and whole equipment takes up an area of 3m ²

The utility model is also applicable to the garden that is quenched to of the more steel band combination grommet of thin and pitch complexity, position, hole in addition.

Most preferred embodiment of the present utility model as mentioned above.
