Description
Technical field
The present invention relates to the thermal treatment unit after a kind of hot-expanding steel tube heat expands, particularly a kind of rotary large-diameter seamless hot-expanding steel tube automatic high-frequency induction hardening device.
Background technology
In modern industry was produced, hot-expanding steel tube was one of large-caliber thin-walled production technology of steel tube, and its characteristics are that operation is simple, mould manufacturing and with short production cycle, and production cost is low.Thereby at present many middle-size and small-size producers adopt heat to expand technology and produce steel pipe, have shortened the Development and Production cycle of product innovation greatly, instant effect, the suitable needs that put goods on the market fast.In the hot-expanding steel tube manufacturing process, after expanding, a lot of steel pipe heat need to carry out quench treatment to satisfy performance requriements.Quench treatment after existing hot-expanding steel tube heat expands adopts the box-type furnace heating mostly, and shrend then often causes pipe deformation big and dangerous, and production efficiency is low and working strength is big, so be difficult to satisfy high product quality and needs cheaply.
Summary of the invention
The purpose of this invention is to provide a kind of rotary large-diameter seamless hot-expanding steel tube automatic high-frequency induction hardening device, by new super large caliber hot-expanding steel tube quench treatment mode, and dielectric heating oven, quenching water tank, rotary actuator and Controlling System are set, thereby solve the deficiency of existing installation technology.
The present invention is achieved through the following technical solutions:
A kind of rotary large-diameter seamless hot-expanding steel tube automatic high-frequency induction hardening device, comprise transmission shaft, rotating roller, high frequency furnace, coil support, quenching water tank, water tank bearing and transmission mechanism, described rotating roller is connected by transmission shaft, drives the rotation of whole rotating roller on transmission mechanism connection and the transmission shaft; Put before and after high frequency furnace and quenching water tank are positioned in the middle of the loading and unloading roller-way and keep at a certain distance away, high frequency furnace be mainly radio-frequency induction coil place on the coil support and can carry out about, the horizontal adjustment position, the quenching water tank places water tank bearing adjustable-height and level attitude, and its inside is provided with several high pressure spray nozzles; Whole device is controlled by Controlling System; Described transmission mechanism rotates by transmission shaft driven rotary roller-way and makes the steel pipe rotation, the certain angle of rotation running roller is advanced steel pipe, control driving motor rotating speed and running roller angle be the rotation and the rate of advance of may command steel pipe just, makes the steel pipe even heating to certain temperature and uniform hardening.
Rotary large-diameter seamless hot-expanding steel tube automatic high-frequency induction hardening device of the present invention, control driving motor rotating speed and running roller angle be the rotation and the rate of advance of may command steel pipe just, can make the steel pipe even heating to certain temperature and uniform hardening; Steel pipe enters in the high frequency furnace, start the intermediate frequency cabinet and rapidly steel pipe is heated by radio-frequency induction coil, select the corresponding different outer diameter of steel pipes of different ruhmkorff coils, Controlling System can be controlled the temperature of heating, make the steel pipe even heating to the necessary temperature of quenching, finish heat-processed; Quenching process of the present invention is finished in the quenching water tank, and the steel pipe after the heating enters in the quenching water tank, at once steel pipe is sprayed water by the high pressure spray nozzle that gathers, and water yield foot, steel pipe rotation, so uniform quenching, cooling are rapidly; Steel pipe continues rotation and advances, and leaves the quenching water tank, reaches the quenching purpose.
The beneficial effect of rotary large-diameter seamless hot-expanding steel tube automatic high-frequency induction hardening device of the present invention is:
(1) apparatus for heating steel tube of the present invention adopts the radio-frequency induction coil of high frequency furnace, utilizes existing hot tube expanding machine to transform a little just and can use, than the large-scale heat treatment furnace equipment of it existing heating large-diameter steel pipe, less investment, floor space is little, and production cost is low, simple operation; The method of high-frequency induction heating can also significantly reduce the pollution to environment, reduces working strength of workers;
(2) its steel pipe is rotary advances, in heating, in the quenching process, heating and uniform quenching, and the pipe deformation amount is little, especially to bigbore hot-expanding steel tube, be convenient to practicality.
