Embodiment 1

[0032] The application of a welding preheating device in this example includes a body, the body includes a positioning mechanism and a preheating mechanism, and an adjustment mechanism, the positioning mechanism is arranged under the side of the weld 7, and the preheating mechanism is arranged at the bottom near the weld 7 On the end face, the adjustment mechanism is connected between the positioning mechanism and the preheating mechanism to adjust the compression degree of the preheating mechanism and the bottom end surface of the weld 7; figure 1 As shown, in this embodiment, there are two sets of bodies, and each set of bodies has two adjustment mechanisms and positioning mechanisms. The adjustment mechanism is a turnbuckle 3, and the positioning mechanism is a support seat 4 with a T-shaped cross section, which is welded by steel plates and steel pipes. (welding foot size 5mm), the steel plate is a circular plate with a diameter of 100mm, the steel pipe diameter is 89mm, an...

Embodiment 2

[0039] The application of a welding preheating device in this example includes a body, the body includes a positioning mechanism and a preheating mechanism, and an adjustment mechanism, the positioning mechanism is arranged under the side of the weld 7, and the preheating mechanism is arranged at the bottom near the weld 7 On the end face, the adjustment mechanism is connected between the positioning mechanism and the preheating mechanism to adjust the compression degree of the preheating mechanism and the bottom end surface of the weld 7; figure 2 As shown, in this embodiment, the adjustment mechanism is a spring 12, the positioning mechanism is a nut barrel 15 fixed on the assembly platform 9 at the bottom end and a bolt 14 that is connected with the nut barrel 15, and the top end of the spring 12 is supported on the preset position by the top piece 11. The bottom surface of the thermal mechanism; the hexagonal head of the bolt 14 is fixedly connected with the bottom end of ...

Embodiment 3

[0042] A flatness measuring device in this example has the same basic structure as that in Embodiment 2. In order to prevent the risk of electric shock when the operator operates, a layer of insulation and heat preservation is laid on the bottom of the heating sheet mold 1, one is to reduce the risk of electric shock It can also play a role in preventing waste of heat source.

Abstract

The invention discloses application of a welding preheating device, and belongs to the technical field of welding preheating. According to the application of the welding preheating device, the welding preheating device comprises a body, wherein the body comprises a positioning mechanism, a preheating mechanism and an adjustment mechanism, the positioning mechanism is arranged below the weld joint side, the preheating mechanism is arranged on the bottom end face close to a weld joint, and the adjustment mechanism is connected between the positioning mechanism and the preheating mechanism and used for adjusting the pressing degree of the preheating mechanism and the bottom end face of the weld joint; and the application of the welding preheating device comprises the step of assembling, the step of mounting and adjustment, and the step of dismounting. According to the application of the welding preheating device, the preheating mechanism is positioned in the position close to a preheated object through the positioning mechanism, the adjustment mechanism is used for adjusting the preheating mechanism and the pressing degree of the preheated object and the preheating mechanism, and thus the technical problem that the preheating time or temperature cannot be controlled easily is effectively solved.

Description

[0001] The application of the present invention is a divisional application, the application number of the parent application: 2015108634936; the name of the parent application: a welding preheating device and its application; the application date of the parent application: 2015-11-27. technical field [0002] The invention belongs to the technical field of welding preheating, and in particular relates to the application of a welding preheating device. Background technique [0003] When the thickness of the welded steel plate is greater than 30mm, there is often a requirement for preheating, that is, the welding part should be heated to 100°C before welding, and then start welding. Preheating measures can effectively prevent welding cracks and deformation. At present, flame heating is generally used. When the thickness of the heated steel plate is more than 100mm, it will take a lot of time to make the steel plate reach the specified temperature, and the energy waste is very...
