Abstract
The utility model discloses an intermediate frequency heating coil with cooling function. The heating coil is prepared from metal tube with square cross section; two vertical tubes are arranged on the upper portion of the heating coil; bottoms of the vertical tubes are provided with an unclosed ring; the right side of the unclosed ring is provided with water spray apertures uniformly distributed along the circumference of the ring; and the center lines of the water spray apertures incline to the center of the unclosed ring relatively. The utility model has the advantage that bending of a steel pipe to be processed is changed from original cold bending to a combination of heating bending and cooling fixing, and phenomena frequently occurred in the cold bending such as wrinkling of bend position and standard exceeding of ovality are effectively avoided, thereby increasing product qualified rate and processing efficiency.
Description
Technical field
The utility model relates to a kind of heater coil, and in particular, the utility model relates to a kind of heating in medium frequency coil for the hydraulic pipe bender system.
Background technology
In the industrial electric construction, the bending process of heavy caliber electrician pipe is a difficult problem of puzzlement electrical construction enterprise always.In traditional construction operation, the bending process of heavy caliber electrician pipe, mostly adopt hydraulic pipe bender to finish, and when using hydraulic pipe bender to process operation, because the processing mode of hydraulic pipe bender is cold stewing operation, the crudy of finished product extremely difficult control, especially simmering and bending position fold or ovality phenomenon such as exceed standard often occurs, cause qualification rate and the working (machining) efficiency of product all to be in lower state, seriously influenced the construction quality of electrical installation project.
In order to overcome the defective of aforementioned prior art, the applicant improves the existing hydraulic pipe bender of managing simmering and bending for the electrician, and in improved device systems, be provided with the heating in medium frequency coil with refrigerating function, to remedy many defectives of aforementioned cold stewing operation.
The utility model content
The purpose of this utility model has the heating in medium frequency coil of refrigerating function exactly by employing, make improved hydraulic pipe bender obtain the application of better effect, thereby solve the existing in prior technology problem.
The technical solution of the utility model is as follows:
A kind of heating in medium frequency coil with refrigerating function, be that square metal tube is made with the cross section, the top of described heating in medium frequency coil is set to two vertical tubes, the bottom of two described vertical tubes is set to not close ring, the front of described not close ring is provided with along the equally distributed spray of its circumference water hole, and the center line in described spray water hole is centroclinal with respect to close ring not.
The quantity in described spray water hole is selected between 15-25 according to the different size of processed steel pipe, is set to 21 generally speaking.
The utility model compared with prior art, its beneficial effect is:
The setting of described heating in medium frequency coil, make processed steel tube bending be changed into the combination of heating simmering and bending and cooling and shaping by original cold stewing processing, effectively avoid in the cold stewing processing mode phenomenons such as the simmering and bending position fold that often occurs or ovality exceed standard, thereby improved the qualification rate of product and the working (machining) efficiency of product.
Description of drawings
Fig. 1 is the front view of the utility model heating in medium frequency coil.
Fig. 2 is the end view of Fig. 1.
Fig. 3 is the rearview of Fig. 1.
Fig. 4 is the use state diagram that the utility model is connected with cooling water pipe in the hydraulic pipe bender system.
Embodiment
The technical solution of the utility model is easier to be understood in order to make, and below in conjunction with drawings and Examples it is improved and does to describe in detail.
Fig. 1, Fig. 2, Fig. 3 have illustrated the structure situation of the utility model heating in medium frequency coil in the mode of front view, end view and rearview respectively; Fig. 4 shows described heating in medium frequency coil connects cooling water pipe in the hydraulic pipe bender system use state diagram.
With reference to Fig. 1, Fig. 2, Fig. 3, described heating in medium frequency coil 1 is that square metal tube is made (the utility model has been selected copper pipe for use) by the cross section, its top is set to two vertical tubes 11, the bottom of two described vertical tubes 11 is set to not close ring 12, the front of described not close ring 12 is provided with along equally distributed several spray water holes 13 of its circumference, and the center line in several described spray water holes 13 is centroclinal with respect to described not close ring 12 all.
With reference to Fig. 4, described heating in medium frequency coil 1 is by two cooling water pipes 2 in two vertical tubes, the 11 connection hydraulic pipe bender device systems on its top, and 12 pairs of not close rings that arrange by its bottom pass being heated by the simmering and bending steel pipe of described not close ring 12, described not close ring 12 fronts are used for along equally distributed several spray water holes 13 of its circumference being sprayed cooling water from cooling water pipe 2 by the simmering and bending steel pipe to what pass described not close ring 12, the consistent set-up mode that favours described not close ring 12 centers of the center line in several described spray water holes 13 is convenient to the utility model to being heated, the steel pipe of simmering and bending sprays cooling and makes its flexural deformation typing.
The quantity in the water hole 13 of spray described in the utility model can be selected to be defined as 15-25, to obtain desirable cooling and shaping effect according to the different size of processed steel pipe.Generally speaking, embodiment equally is set to 21 as shown in drawings.
Design of the present utility model is based on following operation principle:
When the steel pipe of being processed by simmering and bending passed from the center of intermediate frequency heater coil 1, the PLC of device systems control electric current of intermediate frequency fed described heating in medium frequency coil 1, and with the electromagnetic eddy of its formation the steel pipe of being processed by simmering and bending is heated; For making described heating in medium frequency coil 1 under the bigger situation of heating current, keep normal operating state, so in finishing the hollow tube of its making, feed cooling water, the effect of this cooling water has two: the first is passed through from hollow tube, described heating in medium frequency coil 1 is constantly cooled off, make its operating state unaffected; It two is spray water hole 13 ejections from described not close ring 12 fronts, and the steel pipe after heating is bent cools off fast, with control by the quality that bends of simmering and bending steel pipe.
Because hydraulic pipe bender uses the whole system operation process of PLC to control, again in conjunction with application of the present utility model, be convenient to realize heating in the product processing the accurate assurance of simmering and bending and cooling and shaping, avoid the simmering and bending position fold or ovality phenomenon such as exceed standard to occur, overcome the defective of prior art.
Above with reference to drawings and Examples, the heating in medium frequency coil that the utlity model has refrigerating function is schematically described, this description does not have restricted.Those of ordinary skill in the art will be understood that in actual applications the shape of each several part arranges all some change may take place in the utility model, and other staff also may make similar Design under its enlightenment.Only it is pointed out that otherwise break away from design aim of the present utility model that all apparent change and similar Design thereof all are included within the protection range of the present utility model.
