Description

The utility model relates to a rapid heating and rolling forming and quenching equipment for a steel belt liner ring, which belongs to the technical field of piston ring manufacturing equipment.

The piston ring includes a scraper ring and a lining ring. In the prior art, the lining ring is manufactured by first cold-extruding the steel strip into a U to form a section, and then winding it on a quenched threaded rod for heat treatment. The annual heat treatment equipment includes: preheating furnace, Degreasing tank, salt bath furnace, quenching water tank, cleaning line, etc. In addition, a large number of fixtures, auxiliary tools and chemical auxiliary materials (such as acid, alkali, salt, etc.) are required, which makes the manufacturing process of steel belt lining a long time , the equipment covers an area of up to ^80m2 , consumes a lot of energy, pollutes the environment, and the labor intensity of the workers is high. Each shift requires 4 people, and only forty-six steel strip lining rings can be produced per hour. Therefore, the existing manufacturing steel Equipment with lined rings can no longer meet the market demand for piston rings.

The purpose of this utility model is: in view of the above problems, provide a kind of simple in structure, easy to operate, and can make the steel belt backing ring rapidly heat and roll into the garden quenching equipment.

Concrete structure of the present utility model can be described in conjunction with accompanying drawing.

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

Fig. 2 is a sectional view of BB in Fig. 1 .

The figure shows that the utility model is composed of a feeding device I, a heating device II and a quenching device III, and the speed of the steel strip A in the quenching device III is synchronized with the speed in the feeding device I to ensure that the pitch of the steel strip A does not vary. Change, the thermocouple 8 controls the temperature in the heating device II, and the button 9 controls the running state of the whole device.

The feeding device Ⅰ is composed of a feeding plate 1, a worm gear reducer 3, two pairs of pressure wheels 4 mounted on the surface of the box, and a pulley 2 for transmitting power; the heating device Ⅱ is composed of a base 6 and placed on the base 6 The heating furnace 5 is composed of the heating furnace 5 and the heating tube 7 installed in the heating furnace 5. The heating furnace 5 adopts a high-temperature nickel-chromium electric heating wire heating furnace, and the heating tube 7 adopts an OCr25A15 heat-resistant tube or a high-temperature quartz glass tube, and its specification is φ32 ×3.5×1100mm.

Quenching device III is composed of a gear transmission reducer 11, a material shift rod 10 mounted on the surface of the box, a size positioning wheel 12, a cam 22, a concave 23, a material receiving sleeve 24, a lower water tank 16, an upper water tank 17, and an adjustment valve 13 etc., the size positioning wheel 12 can move on the casing surface of the reducer 11, so as to obtain lining rings with different radii. Upper water tank 17 is connected with lower water tank 16 by pipe 15, and upper water tank 17 also connects another pipe 14 to quenching place through regulating valve 13, and the solution after quenching flows back lower water tank 16 to form circulation system. The two transmission shafts 19 and 20 in the reducer 11 are all stretched out of the box, and one end of the shaft 20 is equipped with a concave wheel 23, and two pressing parts 21 that can make the shaft 20 move up and down are respectively provided at the two supports. , (in order to re-wear the steel belt), one end of the shaft 19 is equipped with a cam 22 and a material receiving sleeve 24 that match the concave wheel 23, and the other end is equipped with a sprocket 18 that transmits power.

The working process of this equipment is: the U-shaped steel belt A installed on the feeding tray 1 is synchronously driven by the worm gear reducer 3 and the gear drive reducer 11 at a speed of 46 mm/s, and enters the heating tube 7 in the heating furnace 5, After the U-shaped steel strip A coming out from the heating tube 7 is positioned by the cam 22 and the concave wheel 23, it is immediately quenched into quenched martensite, and the U-shaped steel strip A forms a continuous garden arc under the rolling of the convex and concave wheels simultaneously. The material rod 10 pulls the steel strip A away from the cam 22 to rotate it from the receiving sleeve 24 . The flow of quenching solution is controlled by regulating valve 13.

The outstanding effects of the utility model are: (1) reduce heat treatment processing equipment, fixtures, chemical auxiliary materials, reduce heat treatment procedures, (2) improve productivity, only one person is required to operate each shift, and 534 pieces of steel belt lining rings can be produced per hour , (3) Reduce the operating area, the whole equipment covers an area of 3m ² .

In addition, the utility model can also be applied to the quenching and forming of a thin steel belt combined lining ring with complex pitch and many hole positions.

The preferred embodiment of the present utility model is as described above.
