Description
Technical field
The utility model relates to forming elbow technical field, specifically a kind of heater for hot-bending bends.
Background technology
Along with the fast development of China's economy, the application of bend pipe in fields such as power construction, construction of road and bridge, boiler, boats and ships, furniture and decorations is more and more extensive, and comprises forming mill and hot-bending machine for the bending machine of shaping bend pipe.Hot-bending machine is by pipeline local heat, carries out brake forming bend pipe outside under force conditions.The fire bending device of existing hot bending generally adopts the air core coil in round tube cross section, causes and treats that the pipeline heating of hot bending is uneven, and when hot bending, large-diameter pipeline bending quality is difficult to ensure, easily because heating the uneven problem causing inner-walls of duct wrinkling.
Utility model content
The purpose of this utility model is that the fire bending device overcoming existing bend pipe heats uneven, causes the problem of bending quality instability, provides a kind of heater that the wall of hot-bending bends can be made to be heated evenly.
The technical scheme that the utility model is adopted for achieving the above object is: a kind of heater for hot-bending bends, comprise the heating element heater be electrically connected with heating power supply, high temperature insulation support, pedestal and the horizon bar be fixed on pedestal, high temperature insulation support has two side plates be oppositely arranged, the bottom of two side plates is all hinged on described horizon bar, pedestal is provided with two and lays respectively at outside two side plates in order to support the gripper shoe of high temperature insulation support, two gripper shoes all offer the gathering sill extended along gripper shoe length direction, the sidewall of two side plates is equipped with the fastening bolt for being fixedly connected in gathering sill, described heating element heater forms by turning to spiral resistance wire, and each spiral coil of described resistance wire coiling is all fixed on two side plates, and resistance wire entirety is arranged in arch.
Further, the outside of two side plate bottom is equipped with substrate, and substrate is provided with the annulus that can be set on horizon bar, and described fastening bolt is located on substrate.
Two described gripper shoes are all obliquely installed towards horizon bar.
Beneficial effect: 1, after heating element heater energising, steel pipe by ressitance spiral center can be heated, between the mandrel being generally located at transmission pipeline due to heater and the mould of shaping bend pipe, resistance wire entirety in heating element heater is in arch, the wall of the steel pipe run on mandrel with certain speed can be made to be heated evenly, making steel pipe bending in process distortion evenly, avoiding the problem that inner-walls of duct is wrinkling, improve shaping bending quality;
2, each spiral coil of resistance wire coiling is all fixed on high temperature insulation support, avoids steel pipe running to cause the jitter phenomenon of resistance wire, reduces the deflection of resistance wire, and then avoids because resistance wire is out of shape the uneven phenomenon of the heating that causes;
3, the bottom-hinged of high temperature insulation support is on horizon bar, by the position of fastening bolt in the gathering sill of gripper shoe on adjustment high temperature insulation support, high temperature insulation support is rotated around pin joint, according to bend pipe shape to be formed, finally determines the position of high temperature insulation support.

Detailed description of the invention
As shown in Figure 2, a kind of heater for hot-bending bends, heating element heater 1, high temperature insulation support 2, horizon bar 3 and pedestal 4, heating element heater 1 is electrically connected with heating power supply and in order to heat the pipeline wherein passed through.
As shown in Figure 1, high temperature insulation support 2 has two and is oppositely arranged and the side plate 20 be made up of heat-resistant insulation material, heating element heater 1 forms by self turning to spiral resistance wire 10, each spiral coil of resistance wire 10 coiling is all fixed on two side plates 20 of high temperature insulation support 2 by screw 7, makes the entirety of resistance wire 10 be that arch is arranged.
Wherein, horizon bar 3 is fixed on pedestal 4, and horizon bar 3 is located at the below of high temperature insulation support 2, and the two is arranged in a crossed manner.As shown in Figure 2, the bottom-hinged of two side plates 20 of high temperature insulation support 2 is on horizon bar 3.As shown in Figure 1, pedestal 4 is provided with two and lays respectively at outside two side plates 20 and be all obliquely installed towards horizon bar 3 in order to gripper shoe 5, two gripper shoes supporting high temperature insulation support 2.Two gripper shoes all offer the gathering sill extended along gripper shoe length direction, and two side plates 20 are fixed in gathering sill by the fastening bolt that it is arranged; Outside bottom two side plates 20 is equipped with substrate, and substrate is provided with the annulus that can be set on horizon bar 3, and is located at substrate for the fastening bolt of fixed support plate.When adjusting the setting position of high temperature insulation support 2, first the fastening bolt on side plate being outwarded winding, high temperature insulation support 2 being rotated around its pin joint on horizon bar 3, after turning to correct position, screws fastening bolt, by fixing for side plate on the supporting plate.
The pipeline of bend pipe to be formed passes through from the center of ressitance spiral, to its heating after resistance wire energising.In the specific implementation, between the mandrel that heater is generally located at transmission pipeline and the mould of shaping bend pipe, the overall resistance wire in arch can make the wall of the pipeline run on mandrel be heated evenly, and avoids pipeline bending in process the problem occurring that inwall is wrinkling.And each spiral coil of resistance wire 10 coiling is all fixed on high temperature insulation support 2 by screw 7, size and the position of spiral coil can be adjusted according to actual conditions.
