Abstract
The utility model discloses a combined-type induction hardening device for camshafts, which comprises an induction coil and cooling tubes, and further comprises a shielding ring at the upper and lower end surfaces of the induction coil. An insulation board is arranged between the shielding ring and the induction coil; the induction coil is connected with one end of each cylinder manifold; the insulation board is arranged between the two cylinder manifolds; the cooling tubes are respectively arranged on the outer sides of the two cylinder manifolds; positioning plates are connected with the other ends of the cylinder manifolds; water inlet holes are formed outside the induction coil, and spout holes corresponding to the water inlet holes are formed in the induction coil; and grooves corresponding to the shaft bottoms of the camshafts are formed in the induction coil. In the induction hardening device, three cams next to one another in position can be heated and hardened at the same time, and the grooves corresponding to the shaft bottoms of the camshafts are formed in the induction coil and can prevent the heating and hardening of a non hardening area. Therefore, the induction hardening device provided by the utility model has shortened processing period and improved production efficiency, can prevent induction soft band, and ensures the product quality.
Description
Technical field
The utility model relates to a kind of camshaft induction hardening equipment, relates in particular to the built-up type induction installation that three close cams quench simultaneously.
Background technology
Guarantee its wear resistance for making cam face obtain enough hardness, the thermal treatment of camshaft is main with mid-frequency induction hardening usually, and traditional cam axle induction hardening equipment is a size of confirming inductor block according to the size of need quenching cam.When quenching to the cam of same size induction quenching simultaneously one by one.
But there is the part camshaft to contain the cam of multiple different width dimensions; For example, two narrow cams are close to the wide cam of intermediary on both sides, need to do according to the size of narrow cam and wide cam the induction installation of two kinds of different specification sizes; Earlier wide cam is quenched one by one; Then narrow cam is quenched one by one, cause the process-cycle long easily like this, production efficiency is hanged down inferior problem.Nearer owing to being separated by between the cam in addition, when the narrow cam of heating, cause the temperature of the adjacent wide cam edge position of having quenched to raise and the soft band of formation induction easily.
The utility model content
To above-mentioned prior art, the technical problem that the utility model will solve provides a kind of built-up type induction hardening equipment that soft band generates, can carry out heating quenching to the cam of three close positions simultaneously of avoiding responding to.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: a kind of camshaft built-up type induction hardening equipment comprises ruhmkorff coil, cooling tube; In the middle of being fixed on, said ruhmkorff coil is provided with an end of two omnibus bars of insulcrete; The other end connected positioning plate of omnibus bar, said ruhmkorff coil both ends of the surface are provided with shielding ring, between shielding ring and ruhmkorff coil, are provided with insulcrete; The outside of two omnibus bars respectively is provided with said cooling tube; The ruhmkorff coil outside is provided with the prosopyle, and inside is provided with the spiracle corresponding with the prosopyle, with corresponding groove at the bottom of the cam shaft.
Further, the height of said ruhmkorff coil is greater than three the total position of cam to be quenched width.
Further, said cooling tube is the U type.
Further, said insulcrete is that plate mica is processed.
Compared with prior art, the utlity model has following beneficial effect: can be simultaneously the cam of three close positions be carried out heating quenching simultaneously, and can avoid non-quenching zone to be heated quenching with the corresponding groove that is provided with at the bottom of the cam shaft in the ruhmkorff coil.Not only the process-cycle shortens, production efficiency improves, and prevents to respond to soft band, stabilized product quality.

Fig. 2 is the left view of Fig. 1;
Fig. 3 is the sectional view of the utility model embodiment ruhmkorff coil.
Among the figure: 1, ruhmkorff coil, 2, omnibus bar, 3, insulcrete, 4, the prosopyle, 5, cooling tube, 6, strongback, 7, shielding ring, 8, insulating bolt.
Embodiment
To combine accompanying drawing and embodiment that the utility model is done further to describe below.
Referring to Fig. 1, Fig. 2, a kind of camshaft built-up type induction hardening equipment comprises ruhmkorff coil 1, cooling tube 5; Also comprise the shielding ring 7 that is connected ruhmkorff coil 1 both ends of the surface through insulating bolt 8, be provided with insulcrete 3 between shielding ring 7 and the ruhmkorff coil 1, said ruhmkorff coil 1 is weldingly fixed on an end of two omnibus bars 2; Two omnibus bars 2 make electric current constitute the loop, are provided with the fixing said cooling tube 5 of each welding of the outside of 3, two omnibus bars 2 of insulcrete that plate mica processes between two omnibus bars 2; As preferably; Cooling tube 5 is the U type, and the convenient reflux cooling water of connecting is influenced by pyritous and temperature is too high to guarantee that omnibus bar 2 is unlikely; The other end of omnibus bar 2 is weldingly fixed on the strongback 6, and strongback 6 is used for the axial and radial location of this device; Said ruhmkorff coil 1 outside is provided with prosopyle 4, and inner correspondence is provided with spiracle, the heat-eliminating medium water pipe is switched on the prosopyle 4 of ruhmkorff coil 1; Form water cavity in the ruhmkorff coil 1, spiracle is evenly distributed on the inductor block internal diameter, like this when quenching; WATER AS FLOW MEDIUM is 4 entering ruhmkorff coils, 1 water cavity through the prosopyle; Spray and go out from spiracle again, cam is accomplished quenched, ruhmkorff coil 1 inside is provided with and corresponding groove at the bottom of the cam shaft.
As shown in Figure 3, the external diameter of ruhmkorff coil 1 is C, confirms the internal diameter A of ruhmkorff coil 1 according to the diameter dimension of camshaft, guarantees that camshaft can pass through ruhmkorff coil 1 smoothly, confirms the total height B of ruhmkorff coil 1 according to total position width of three cams of need quenching.Because cam is the position of need hardening, and the axle end between the cam is non-hardened area, therefore ruhmkorff coil 1 inner diameter location corresponding at the bottom of the axle is made into groove, can avoid non-quenching zone to be heated quenching like this.
Set processing parameter, when camshaft moves to specified location, ruhmkorff coil 1 heats to cam through electromagnetic induction; After being heated to preset temperature; WATER AS FLOW MEDIUM gets into ruhmkorff coil 1 water cavity through prosopyle 4,, cools off to cam by the ejection of the spiracle on the internal coil diameter through pressure; Heating quenching when so once can accomplish three close cams is accomplished the back camshaft and is continued to move to next grade quenching position and proceed quenching.
