Abstract
The invention discloses a combined induction heating coil. The combined induction heating coil comprises a small-diameter coil (1), a transition coil (2) and a large-diameter coil (3), and is characterized in that the transition coil (2) is a conical coil, the small-diameter coil (1) is connected with a small-diameter end of the transition coil (2), the large-diameter coil (3) is connected with a large-diameter end of the transition coil (2), and the small-diameter coil (1), the transition coil (2) and the large-diameter coil (3) are each composed of a plurality of turns of coils. The combined induction heating coil is uniform in heating, simple, feasible, economical and practical.
Description
Technical field
The invention belongs to heater coil technical field, relate in particular to a kind of composite type load coil.
Background technology
The high temperature alloy part higher to performance requirement carry out head shaping time, usually need the mode taking hot upsetting.During hot upsetting, common mode of heating mostly is and utilizes load coil to carry out infrared high-frequency induction heating.General part mostly was the hot upsetting blank of rod-like morphology before upsetting head, therefore only need use conventional straight barrel type load coil during heating, can make the head moulding section thermally equivalent of hot upsetting blank, thus obtain good plastic deformation ability.
For little 12 jiaos of large flange valve snail bolt parts that nickel base superalloy is made, the head moulding section of its hot upsetting blank is thin head conical transition thick bar form.When heating it with straight barrel type load coil, easily cause blank to be heated inequality, the temperature of thin head part is lower than the temperature of thick bar part, so that causes part head difficult forming when upsetting.Specifically, when the temperature of thick bar part reaches requirement, the temperature of thin head part is much lower, so little 12 angle parts of part head are shaping not full when hot upsetting, and Yin Wendu does not reach requirement and makes its resistance of deformation increase, easily cause former to damage, greatly increase production cost undoubtedly like this.
Summary of the invention
The object of the invention is to overcome above-mentioned shortcoming and provide a kind ofly add thermal balance, simple possible, economical and practical composite type load coil.
The object of the invention and solve its technical problem underlying and realize by the following technical solutions:
Composite type load coil of the present invention, comprises thin footpath coil, transition coil, particle size coil, and wherein: transition coil is coniform coil, thin footpath coil is connected with the miner diameter end of transition coil, and particle size coil is connected with the bigger diameter end of transition coil.
Combinations thereof formula load coil, wherein: described thin footpath coil, transition coil and particle size coil form by some circle coils.
The present invention compared with the existing technology has obvious advantage and beneficial effect.From above technical scheme, composite type load coil of the present invention, described transition coil is coniform coil, thin footpath coil is connected with the miner diameter end of transition coil, particle size coil is connected with the bigger diameter end of transition coil, solve use conventional straight barrel type load coil heat thin head conical transition thick bar blank time run into be heated unbalanced, thin head part is lower and cause the difficult problem that head cannot be well shaping than thick bar portion temperature, when achieving the hot upsetting of thin head conical transition thick bar, the heating-up temperature of whole head materials reaches uniformity, thus the product making upsetting make has good performance requirement, the material of thin footpath coil, transition coil, particle size coil is identical with conventional coil, and heating process protects model effectively, and cost is lower.In a word, the present invention adds thermal balance, simple possible, economical and practical, and the induction heating being applicable to thin head conical transition thick bar is promoted the use of.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is using state figure of the present invention.
Identify in figure:
1, thin footpath coil; 2, transition coil; 3, particle size coil; 4, thin head; 5, transition circular cone; 6, thick bar.
Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, to the composite type load coil embodiment proposed according to the present invention, structure, feature and effect thereof, be described in detail as follows.
See Fig. 1, composite type load coil of the present invention, comprises thin footpath coil 1, transition coil 2, particle size coil 3, wherein: transition coil 2 is coniform coil, thin footpath coil 1 is connected with the miner diameter end of transition coil 2, and particle size coil 3 is connected with the bigger diameter end of transition coil 2.Described thin footpath coil 1, transition coil 2 and particle size coil 3 form by some circle coils.
During use, see Fig. 2, composite type load coil is linked in the head of hot upsetting blank, thin footpath coil 1, transition coil 2 and particle size coil 3 is made to be fitted in thin 4 of hot upsetting blank head, the outside of transition circular cone 5 and thick bar 6 respectively, when composite type load coil electrified regulation, the various piece homogeneous heating to hot upsetting blank head can be realized.
The above, it is only preferred embodiment of the present invention, not any pro forma restriction is done to the present invention, anyly do not depart from technical solution of the present invention content, the any simple modification done above embodiment according to technical spirit of the present invention, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
Claims (2)
1. a composite type load coil, comprise thin footpath coil (1), transition coil (2), particle size coil (3), it is characterized in that: transition coil (2) is coniform coil, thin footpath coil (1) is connected with the miner diameter end of transition coil (2), and particle size coil (3) is connected with the bigger diameter end of transition coil (2).
