Abstract

The invention relates to a manufacturing process of a steel engine cylinder sleeve. By utilizing the manufacturing process, the mechanical performances and the mechanical strength of an engine are improved, the distance of the center distance among all the cylinders is reduced, the volume of an engine body is reduced, the weight of the whole engine is reduced by 20%, the requirements of light weight and high-speed driving for the modern cars, coaches and trucks are met, and the purpose of saving raw materials and energy is achieved.

Description

Steel air cylinder sleeve of engine manufacturing process

Technical field

This aspect relates to cylinder liner, is specifically related to a kind of steel air cylinder sleeve of engine manufacturing process, is applicable to car, large and medium bus, truck, and motor reaches lightweight.

Background technique

At present, air cylinder sleeve of engine all is to adopt cast iron cylinder cover, alloy cast iron cylinder jacke, because what the material of cylinder liner adopted is cast iron, in order to guarantee enough mechanical propertys and mechanical strength, its cylinder liner must have certain thickness to support, its supporting shoulder is outer through also big simultaneously, therefore motor is when design, and in order to guarantee the installing space of cylinder liner, its matrix design is bigger, weight is big, can not adapt to the requirement of Hyundai Motor lightweight and high speed driving.

Summary of the invention

The objective of the invention is to: a kind of steel air cylinder sleeve of engine manufacturing process is provided, utilize steel cylinder liner material of the present invention to make cylinder liner, the mechanical property and the mechanical strength of motor have been improved, reduced the distance of each cylinder centre distance, dwindled the volume of body, the weight saving of complete machine 20%, adapt to the requirement of Modern Car, passenger vehicle, truck lightweight high speed driving, reach save material, the purpose of the energy.

The technological scheme that technical solution problem of the present invention is adopted is: adopt the seamless steel pipe of low carbon steel content material to make cylinder liner.

Its technological process is: blanking → car both ends of the surface and inner stopper → boring endoporus → corase grind cylindrical → thick internal grinding → correct grinding cylindrical → flange → rolling → right boring endoporus → finish turning descends seam → chromium plating → microhoning endoporus → cleaning → check → sign → spray rust preventive oil → packing → warehouse-in outward.

The invention has the beneficial effects as follows: the cylinder liner by steel material is made, realize the requirement of automobile lightweight, high speed driving, reach the economical with materials and the energy and prolong the motor purpose in working life.

Description of drawings

Fig. 1 is a process flow diagram of the present invention.

Embodiment

As shown in Figure 1, technological process is:

1. blanking

Steel pipe is clamped on the anchor clamps of special saw machine, guarantees the center line of steel pipe and the perpendicularity of saw blade, and 1 millimeter surplus is respectively stayed at two ends;

2. car both ends of the surface and inner stopper

The blank cylinder sleeve is contained on the mandrel of machine tool, cuts both ends of the surface after the tensioner, then the car inner stopper;

3. cylindrical turning

Cylinder sleeve is packed on the mandrel of blooming expanding sleeve of machine tool, size, and surplus is stayed 0.25 millimeter of diametric(al);

4. boring endoporus

Dispose blooming expanding sleeve with special boring mill, the port clamping device is the transition fit state when cylinder sleeve is put into anchor clamps, and the port spiral clamps;

5. corase grind cylindrical

Cylinder sleeve bore adds the plasticity lining, works the purpose that strengthens cylinder sleeve intensity, puts into and roughly grinds cylindrical on the coreless grinding machine, 0.08 millimeter of made allowance;

6. thick internal grinding

The cylinder sleeve cylindrical adds the plasticity overcoat, adopts internal grinding machine to carry out the grinding endoporus;

7. correct grinding cylindrical

Cylinder sleeve bore adds the plasticity lining, puts into to finish grind cylindrical on the coreless grinding machine, is milled to final size;

8. flange

Adopt special-purpose press, the anchor clamps transition fit, the concavo-convex mold pressing of Top end moulding is tight, forms flange;

9. rolling

Adopt bearing on machine tool, to carry out rolling;

10. right boring endoporus

Adopt the T716 special boring mill, the anchor clamps form, blooming expanding sleeve, spiral clamp;

11. finish turning descends seam outward

Anchor clamps adopt fluidity filler anchor clamps, general lathe;

12. chromium plating

Cylinder sleeve integral body is carried out chromium plating and is handled the raising wear resistance;

13. microhoning endoporus

Use honing machine, anchor clamps transition fit formula, pressure limit;

14. clean

Convert water with washing agent and clean, washing agent 5%, water 95%;

15. check

Interventions Requested: tolerance of size, shaped position tolerance, hardness, platform reticulate pattern.

16. sign

With laser marking machine apart from cylinder sleeve bottom to lower end surface 20 millimeters locate the sign.

17. spray rust preventive oil

The whole mechanically spraying rust preventive oil of cylinder sleeve.

18. packing

Pack cylinder sleeve with plastic bag sealing, put into the individual packaging box then, the carton of putting into 6 dresses again seals.

19. warehouse-in

Sort out warehouse-in by kind.

Claims

1. steel air cylinder sleeve of engine manufacturing process, it is characterized in that: this technological process is: blanking → car both ends of the surface and inner stopper → boring endoporus → corase grind cylindrical → thick internal grinding → correct grinding cylindrical → flange → rolling → right boring endoporus → finish turning descends seam → chromium plating → microhoning endoporus → cleaning → check → sign → spray rust preventive oil → packing → warehouse-in outward.
