Abstract
The utility model discloses a rectangular intermediate-frequency sensor continuously spraying-quenching on side surfaces. The body of the sensor adopts a square copper tube; a notch formed by the inlet end and the outlet end of the copper tube is arranged at a corner of the body of the sensor; and a water spout is formed at a downward inner corner of the body of the sensor. The rectangular intermediate-frequency sensor has the benefits that the problems of molten zone, cracked edges and corners, and large deformation of the conventional quenching sensor are successfully solved, the alignment cost is reduced and the working efficiency is greatly improved due to the rational design of the sensor.
Description
Technical field
The utility model belongs to the medium frequency induction hardening technical field, relates to surface, a kind of square-section and sprays the intermediate frequency inductor of quenching continuously.
Background technology
Common four faces are wanted the rectangular parallelepiped workpiece of hardness, adopt integral quenching usually, if hardness requirement is higher, are limited by the influence of free area and critical size, generally adopt four faces respectively induction heating continuously spray quench.Distortion is bigger like this, and efficient is extremely low, and in order to prevent adjacent quenching face owing to rapid heating causes cracking, adjacent facets must not quench by about 10mm near edges and corners; Sometimes adopt four faces to spray cold quenching simultaneously continuously.The inductor block gap is merely 1-2mm, and inductor block strengthens the gap in edges and corners through R, prevents edge effect.Because the inductor block gap is less, precooling is not enough, during quenching, and the corner angle easy of crack, and also the inductor block breach is at big in-plane, and indentation, there has soft band like this, and is out of shape bigger.
Summary of the invention
The purpose of the utility model provides surface, a kind of square-section and sprays the intermediate frequency inductor of quenching continuously, when having solved the hard surfacing of four sides, square-section of the prior art, and the big and ineffective problem of the soft band of existence, cracking, distortion.
The technical scheme that the utility model adopted is, surface, a kind of square-section is the spray intermediate frequency inductor of quenching continuously, and inductor body adopts square copper tube to make, and copper tube entrance end and the breach of exit end formation are arranged on a jiao of inductor body.The interior angle down of described inductor body has spiracle.
The beneficial effect of the utility model is, the appropriate design through inductor block has successfully solved the soft band that existing quenching inducer brings, and the corner angle cracking is out of shape bigger problem, has reduced the alignment cost, has also improved working efficiency widely.

Among the figure, 1. inductor body, 2. workpiece, 3. entrance end, 4. exit end, 5. breach, 6. spiracle
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is elaborated.
Fig. 1 is the rectangle sensor structure synoptic diagram of the utility model; Inductor body 1 adopts the square copper tube of length of side 10-12mm to make; Copper tube wall thickness 1.5-2mm, the breach 5 that copper tube entrance end 3 and exit end 4 constitute is arranged on a jiao of inductor body 1, sees Fig. 1 a; The interior angle down of inductor body 1 has spiracle 6, sees Fig. 1 b.
Fig. 2 is that the rectangle inductor block and workpiece 2 relative installations of the utility model concern synoptic diagram.Inductor body 1 is sleeved on the weld height of workpiece 2, and the breach 5 of inductor body 1 must be facing to corner angle of workpiece 2.
Fig. 3 is that the rectangle inductor block and the workpiece 2 of the utility model installed relation and gap synoptic diagram relatively, and monolateral assemblage gap is 6-8mm.Through being placed on the corner angle direction to the breach of inductor body 1, strengthen the gap of workpiece 2 and inductor body 1, solved the problem that conventional hard surfacing exists effectively, improved working efficiency widely.
The rectangle inductor block will form the loop breach must occur, and the loss of indentation, there magneticline of force is serious, and temperature is relatively low, in addition indentation, there cooling not enough, when freely not causing hard surfacing, indentation, there hardness is on the low side.Be not difficult to find through analysis; Edges and corners are because edge effect; Temperature reaches quenching temperature easily, and edges and corners belong to interfacial angle in addition, because the cooling rate of interfacial angle is greater than the cooling rate on one side angle (plane); Be placed on the corner angle position to the breach of inductor body 1 like this, not only solved rectangle inductor block indentation, there workpiece temperature and be not easy to reach the problem of normal quenching temperature but also solved the insufficient problem of this place's cooling.Because corner angle stress relative complex, easy of crack through strengthening the gap of inductor block, reaches the precooling time that increases, and reduces the corner angle quenching temperature, thus corner angle rimose risk when having reduced quenching.Because this rectangle inductor block is that four faces quench simultaneously, does not have soft spots, has so also reduced quenching strain effectively, has improved working efficiency.
The shape of the rectangle inductor block of the utility model is a profiling blowing inductor block, and the monolateral gap of workpiece 2 and inductor body 1 is 6-8mm.Workpiece 2 is wanted with one heart when being installed with inductor body 1.When being installed, workpiece 2 will be placed in the inductor body 1, and breach is facing to the corner angle of workpiece 2, and workpiece 2 is impartial with inductor body 1 all directions gap.
The rectangle inductor block of the utility model belongs to the blowing inductor block, makes simply, and is easy to operate, and solved soft band effectively, the corner angle cracking, and the problem that workpiece deformation is big, working efficiency improves significantly.
