Introduction to convex shaft core quenching in the use of high-frequency quenching equipment

Induction heating equipment request for convex axis:

The surface treatment technical requirements of 1.45 steel camshaft center: the nominal angle of the cam, supporting shaft diameter and fair wheel is 48-58HRC, the softening layer depth is 2-5mm, the angle of the cone is 45-58HRC, and the softening layer depth is 2-5mm.

Convex shaft core quenching process:　　　

A circular sensor is used to quench the cam and other quenching positions of the camshaft center one by one or as a whole.

Convex shaft core quenching sensor:

1. The induction heating sensor should be manufactured and designed according to the requirements. Its shape can be formed into a profile or a circle. Its height is 4-8mm higher than the center of the convex shaft. The gap between the inner diameter and the shaft diameter is between 3-4mm to avoid gaps. There is no obvious difference in angle. At the same time, it is necessary to observe that the position of the sensor and the convex shaft should be relative to each other. After the surface of the convex axis is softened by induction hardening, its austenite grains are refined, resulting in a high surface angle, improved wear resistance and fatigue resistance, and small deformation, high frequency, energy saving, and automation. and mechanized operations. The workpiece automatically and accurately drops to the next position that requires quenching, and also proceeds according to the set heating time, spraying time, starting time, and spraying delay sequence. In general, the convex shaft core heat treatment process of external combustion engines such as buses and tractors mostly uses induction heating to achieve surface heat treatment. It has the characteristics of fast heating progress, stable quality, energy saving, high level of mechanization and automation. The process is mature and easy to operate. This process can significantly improve the tensile strength, angle, wear resistance and fatigue limit of the base surface of the convex shaft core. The core still maintains residual plasticity and toughness, and can respond to the convex shaft according to its structure and technical requirements. The cam, supporting shaft diameter, fair wheel and gear wheel sequence of the center are mainly subjected to induction hardening treatment before finishing. The specific process is: programming the quenching tool according to the drawing size of the convex axis center.　

2. Technical requirements for alloy pig iron camshaft center: the nominal angle of the cam, supporting shaft diameter and fair wheel is 48-58HRC, the softening layer depth is 2-5mm, the angle of the cone is 45-58HRC, and the softening layer depth is 2-5mm. When producing in large quantities, all quenching positions of the convex shaft center should be heated at the same time. If heated in sections, soft spots or soft bands will easily appear, which directly affects the wear resistance of the convex shaft center surface. For its Service life, etc. have a direct impact. Based on the data from the process test, set the rotation speed of the workpiece and the power scale of the induction heating power supply. Main settings: initial position determination, heating time, heating stop, spraying time.

a. Circular sensor: It adopts the convex axis winding mode. The inner diameter of the sensor is larger than the supporting diameter, and the gap is larger.　

2. The 1.5-2mm radiation hole on the sensor is ensured to be unobstructed, the water pressure meets the design requirements, and the convex axis may be twisted or motionless.

b. Imitation camshaft heart-shaped sensor: Same as high-frequency sensing equipment or specific requirements for special shapes. The gap between the cam and the sensor is very small. Since the angles are uniform, it can be determined according to the depth of the softening layer of each part of the camshaft center. Changing the shape of the profiling, this type of sensor is divided into two types: single circle and double circle. The use of induction heating can improve the strength and wear resistance of the convex axis, ensuring high fatigue strength and service life during work. The heating time can be set by the sequence of the quenching tool, or by measurement using an infrared thermometer. By analogy, all work stations will be quenched.

Price analysis of high-frequency induction heating equipment and performance review of high-frequency annealing equipment

1. The only prerequisite that determines the price of high-frequency induction heating equipment is whether the technology is advanced or not; currently, a number of low-end high-frequency heating equipment appear in the domestic market, which are extremely cheap, but cause a lot of trouble to customers in use. When used, it not only fails to meet the process requirements, but also easily causes harm to the human body.

2. According to the comprehensive performance of high-frequency induction heating equipment, the superior and outstanding performance of high-frequency induction heating equipment is mainly reflected in the reasonable configuration of the overall equipment, including advanced high-end electronic components, as well as excellent circuit integration, as well as operation Side comfort and safety must be taken into consideration; to sum up, whether it is a business or an individual purchasing high-frequency induction heating equipment, do not just look at the price, but also look at the cost-effectiveness, the advanced nature and service life of the equipment.
