Description
Technical Field
The utility model relates to a toughened glass manufacturing field especially relates to an electric heating element for toughened glass heating furnace.
Background
The toughened glass is prestressed glass, has the advantages of high strength, good thermal stability, safe use and the like, and is widely applied to the fields of doors and windows of high-rise buildings, glass curtain walls, lighting ceilings, automobile glass, photovoltaics and the like. The existing toughened glass is divided into physical toughened glass and chemical toughened glass according to the production process, and for the physical toughened glass, the glass coming out of a heating furnace is rapidly cooled by adopting an air grid in the production process; the electric heating element is used as a main component in the heating furnace, and the welding quality of the element directly influences the finished product quality of the toughened glass. As shown in fig. 1, in a conventional electric heating element, one end of a heating rod is inserted into the front end of an outlet pipe, a through groove is formed at the position, close to the front end, of the outlet pipe, the heating rod and the outlet pipe are fixedly welded at the through groove, and a fixing nut and a wire pressing terminal clamped between the two fixing nuts are sleeved on the outer wall of the outlet pipe, close to the rear end; because the heating rod is fixedly connected with the eduction tube by direct welding, the welding spot is seriously oxidized in the using process, the heating rod is easy to have the phenomena of desoldering, breaking and the like, the service life is short, and the using requirement is difficult to meet.
Disclosure of Invention
The utility model aims to provide an electric heating element for a toughened glass heating furnace, which has simple structure and simple and convenient processing.
In order to achieve the above purpose, the utility model can adopt the following technical proposal:
the electric heating element for the toughened glass heating furnace comprises an extraction pipe and a heating rod arranged at the front end of the extraction pipe, wherein a wire pressing terminal and a fixing nut for clamping the wire pressing terminal are sleeved at the rear part of the extraction pipe; the heating device is characterized in that a connecting sleeve is arranged between the leading-out pipe and the heating rod, one end of the connecting sleeve extends into the leading-out pipe, the heating rod penetrates through the connecting sleeve extending out of the leading-out pipe, extends to the end part of the connecting sleeve and is welded with the connecting sleeve into a whole, and the front end of the leading-out pipe is welded with the connecting sleeve into a whole.
The utility model has the advantages of simple structure and simple and convenient processing and manufacturing. The heating rod, the connecting sleeve and the lead-out tube are welded step by step and are formed by assembly welding, so that the lead-out tube is indirectly connected with the heating rod through the connecting sleeve, compared with the mode that the original lead-out tube is fixedly connected with the heating rod by direct spot welding, the indirect contact area of the heating rod and the lead-out tube is greatly increased, the structural strength is improved, the conductivity and the external interference resistance are enhanced, the oxidation phenomenon of welding spots is reduced, the phenomena of desoldering, breaking and the like of the heating rod are reduced, and the service life of an electric heating element is greatly prolonged.

Fig. 2 is a schematic structural diagram of the present invention.
Fig. 3 is a schematic structural view of the heating rod and the connecting sleeve in fig. 2.
Detailed Description
As shown in figure 2, toughened glass heating furnace uses electric heating element, including fairlead 1 and the heating rod 2 of arranging the 1 front end of fairlead in, the cover is equipped with line ball terminal 3 at 1 rear portion of fairlead, suit fixation nut 4 respectively on the fairlead 1 of line ball terminal 3 preceding, back both sides, the fixation nut 4 that is located the 3 front sides of line ball terminal welds admittedly on fairlead 1 outer wall to can the clamping line ball terminal 3 when screwing up fixation nut 4 of line ball terminal 3 rear sides.
A connecting sleeve 5 is arranged between the eduction tube 1 and the heating rod 2, one end of the connecting sleeve 5 is deep into the eduction tube 1, the heating rod 2 penetrates through the connecting sleeve 5 extending out of the eduction tube 1, extends to the end part of the connecting sleeve 5 and is welded with the connecting sleeve 5 into a whole, and the front end of the eduction tube 1 is welded with the connecting sleeve 5 into a whole.
And (3) actual processing: firstly, inserting the rear end of a heating rod 2 into a connecting sleeve 5, wherein the rear end of the heating rod 2 is flush with the rear end of the connecting sleeve 5 (as shown in fig. 3), and welding and fixedly connecting the heating rod 2 and the rear end of the connecting sleeve 5, and certainly, in order to enhance the firmness, the front end of the connecting sleeve 5 can also be welded and fixedly connected with the outer wall of the heating rod 2; then, inserting the connecting sleeve 5 and the heating rod 2 into the front end of the eduction tube 1, reserving a section at the front end of the connecting sleeve 5 outside the eduction tube 1, and fixedly welding the front end of the eduction tube 1 and the outer wall of the connecting sleeve 5; finally, the fixed nut 4 and the line pressing terminal 3 are sleeved to finish the processing and manufacturing of the electric heating element.
