Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art. It should be noted that, in the present invention, the embodiments and features of the embodiments may be combined with each other without conflict. The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
As shown in fig. 1 to 3, the utility model provides a pair of little takeover fillet weld heat treatment armour formula heating plate, armour formula heating plate are mainly to the improvement on current ceramic resistance heating rope form, constitute including potsherd 101 and heater strip 102 and heating connector 103 triplex, potsherd 101 is in the same place through whole heater strip 102 series connection, generally formulate the heating plate of different sizes to takeover and takeover fillet weld's different specifications, heating connector 103 is installed at heater strip 102 both ends, is connected with equipment for heat treatment. And starting the heating sheet component part, wherein the heating sheet at the connecting pipe is unfolded to be in a rectangular shape, and the heating sheet at the welding seam is unfolded to be in a fan-shaped shape.
As shown in fig. 4 to 8, the starting heating plate can be directly sleeved on the welding seam needing heat treatment of the BOSS head or the small branch pipe during use. After the heating sheet is attached to the flat surface, an iron wire, a snap ring or a fixing device is used for fixing the heating sheet at the position required by the process, and the specific using method is provided.
The resistance heating sheet (ring) is designed for the special structural member on the spot of the work welding heat treatment, and the heat treatment binding for the special structural member can not meet the process and standard requirements, so the special resistance heating sheet can be designed according to the structural characteristics of the member to meet the heat treatment work requirement of the spot special-shaped member.
Aiming at the heat treatment work of the welding seam of the small connecting pipe, the resistance heating rope with small pipe diameter on the spot is not easy to wind, and the heating rope is easy to accumulate at the fillet welding seam of the pipe seat, so that the expansion and fracture of the heating rope are frequently caused by the increase of the stress after the temperature rise of the heat treatment, and the heat treatment work is interrupted. The heating rope winding is fixed insecure, because there is the slope in general fillet weld, so the heating rope easily takes place deformation and causes the phenomenon of partially warm, and partial takeover length is not enough, and the heating rope can't be used, leads to the unsatisfied standard requirement of heating width, and heating power can't satisfy the work needs. Aiming at the difficult problem of heat treatment of the small connecting pipes, corresponding tools and armored heating sheets can be designed aiming at the connecting pipes with different specifications, so that the field heat treatment can be normally carried out, the working efficiency is improved, and the working failure caused by improper heat treatment is avoided. The design of the small connecting pipe welding seam armored heating sheet and the tool is shown in figures 1 to 3.
Design description: the armored heating sheet is manufactured according to the specification of the small connecting pipe, and is directly sleeved to the position of the connecting pipe welding line when in use, and the connecting pipe fillet welding line with the same specification or similar specification can be used for heat treatment. When the length of the connecting pipe does not meet the requirement of the heat treatment process, the heating width can be extended by using the tool so as to meet the process requirement. The heat treatment of the small adapter is schematically shown in fig. 4 to 8.
(1) Adopt flexible ceramic resistance heating or far infrared radiation heating, every side heating width is no less than 4 times of weldment thickness, and the extension frock length that can make is 100mm commonly for extension heating width.
(2) The heating plate is divided into two parts including a connecting pipe heating area and a welding seam covering area, the length of the heating area is not less than the standard and process requirements, the heating width of a common small connecting pipe is less than or equal to 100mm, and therefore the length of the heating plate of the connecting pipe heating area can be designed to be 100 mm; and the inner circle of the welding seam coverage area is the circumference of the connecting pipe, and the width of the coverage area is the width of the fillet welding seam of the connecting pipe. Ensuring that the covering area is just fit to the whole welding seam surface. The pipeline part is bound by a conventional heating sheet, so that the process requirement can be met.
Although the invention has been described in detail with respect to the general description and the specific embodiments, it will be apparent to those skilled in the art that modifications and improvements can be made based on the invention. Therefore, such modifications and improvements are intended to be within the scope of the invention as claimed.
