[0011] Optionally, the nut tightening section, the bolt tightening section and the circular groove have the same height.

[0012] By adopting the above solution, the surface of the heating side plate is made smoother, thereby achieving a better heating effect of the heating plate.

[0013] Optionally, a plurality of the connection structures are provided, and the plurality of connection structures are arranged in a rectangular array.

[0015] Optionally, the bolt column is connected to a tightening tool for facilitating the screwing of the bolt column. An insertion groove is provided on the side of the stud tightening section facing away from the stud threaded section, an insertion block is provided on one side of the tightening tool, and a tightening cap is provided on the side of the tightening tool facing away from the insertion block for convenience of tightening by the operator. When the bolt column needs to be tightened, the insertion block is inserted into the insertion groove, and the operator uses a wrench in conjunction with the tightening cap to drive the tightening tool to rotate.

[0016] By adopting the above solution, since the bolt column and the surface of the heating plate are flat, an ordinary wrench cannot be used to screw the bolt column into the first threaded hole. Therefore, the insertion block can be inserted into the insertion groove, and then the tightener can be tightened with a wrench to drive the bolt column to be screwed into the first threaded hole, so that the operator can install the bolt column more conveniently.

[0017] Optionally, an insertion groove is provided on a side of the bolt cap facing away from the bolt column.

[0020] 1. By setting up threaded columns and threaded columns, the two heating side plates are fixed to each other, thereby reducing damage to the heating core;

[0021] 2. By making the bolt column parallel to the surface of the heating side plate, and the bolt cap parallel to the surface of the heating side plate, the heating effect of the heating side plate is better;

[0022] 3. The tightener is provided to make it easier for operators to tighten the threads. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] The present application is further described in detail below with reference to the accompanying drawings.

[0028] Reference Figure 1 and Figure 2A welding machine heating plate includes a heating core 1 and a heating side plate 2. Two heating side plates 2 are provided. The two heating side plates 2 are located on opposite sides of the heating core 1. A first threaded hole 21 is opened on the surface of the heating side plate 2. A through hole 11 is opened on the surface of the heating core 1. A connecting structure 3 is provided between the heating side plate 2 and the heating core 1. The connecting structure 3 includes a bolt column 31 and a bolt cap 32. The bolt column 31 includes a stud thread section, a stud center section and a stud connection section 314. The stud thread section, the stud center section 313 and the stud connection section 314 are connected in sequence. They are all integrally formed, and the diameters of the stud thread section, the stud center section 313 and the stud connecting section 314 decrease successively. The stud thread section and the stud connecting section 314 are both provided with external threads. The bolt cap 32 includes a nut thread section 322. The outer side of the nut thread section 322 is provided with an external thread, and the nut thread section 322 is provided with a second threaded hole 323. The stud connecting section 314 is threadedly connected in the second threaded hole 323. The stud thread section and the nut thread section 322 are respectively threadedly connected in the two first threaded holes 21, and the stud center section 313 is located in the through hole 11. When installing the heating plates, place the two heating side plates 2 on both sides of the heating core 1, then pass the bolt column 31 through the through hole 11, screw the bolt thread section 312 into the first threaded hole 21 of the heating side plate 2, then screw the nut thread section 322 into the first threaded hole 21 of the other heating side plate 2, and at the same time screw the stud connecting section 314 into the second threaded hole 323 to threadably connect the bolt column 31 and the threaded nut, so that the two heating side plates 2 are fixed to each other, thereby reducing the force on the heating core 1 and making the heating core 1 less susceptible to damage.

[0029] Reference Figure 1 and Figure 2 A circular groove 22 is formed on the surface of the heating side plate 2 on the side facing away from the heating core 1. The circular groove 22 is coaxial with the first threaded hole 21 and has a larger diameter than the first threaded hole 21. A stud tightening section 311 is provided on the end of the stud center section 313 facing away from the stud connection section 314. The stud tightening section 311 is located within the circular groove 22. A nut tightening section 321 is provided on the side of the nut threaded section 322 facing away from the bolt column 31. The nut tightening section 321 is located within the circular groove 22. When the bolt column 31 and the bolt nut 32 are threadedly connected, the stud tightening section 311 and the nut tightening section 321 are located within the circular groove 22, and the bolt column 31 and the nut nut are mutually constrained, thereby further tightening the connection between the connecting structure 3 and the heating side plate 2.

[0030] Reference Figure 1 and Figure 2 The heights of the nut tightening section 321, the bolt tightening section and the circular groove 22 are the same, so that the surface of the heating side plate 2 is smoother, thereby making the heating effect of the heating plate better.

[0031] Reference Figure 1 and Figure 2There are multiple connection structures 3, and the multiple connection structures 3 are arranged in a rectangular array. This makes the force on each part of the heating side plate 2 more uniform, not only making the connection between the heating side plate 2 and the heating core 1 more secure, but also making the heating side plate 2 less likely to be damaged.

[0032] Reference Figure 2 and Figure 3 The bolt column 31 is connected to a tightening tool 4 for conveniently screwing in the bolt column 31. The stud tightening section 311 is provided with an insertion groove 42 on the side away from the stud threaded section, and the bolt cap 32 is provided with an insertion groove 42 on the side away from the bolt column 31. An insertion block 41 is provided on one side of the tightening tool 4, and a tightening cap 43 is provided on the side of the tightening tool 4 away from the insertion block 41 for easy tightening by the operator. When the bolt column 31 is flat with the surface of the heating plate, an ordinary wrench cannot be used to screw the bolt column 31 into the first threaded hole 21. Therefore, the insertion block 41 can be inserted into the insertion groove 42, and then the tightening tool 4 can be tightened with a wrench, thereby driving the bolt column 31 to be screwed into the first threaded hole 21, so that the operator can install the bolt column 31 more conveniently.

[0033] The specific implementation principle of the present application is as follows: when installing the heating plate, the two heating side plates 2 are placed on both sides of the heating core 1, and then the bolt column 31 is passed through the through hole 11, and the insertion block 41 is inserted into the insertion groove 42, and then the tightener 4 is tightened with a wrench to drive the bolt column 31 to be screwed into the first threaded hole 21, and then the nut threaded section 322 is screwed into the first threaded hole 21 of the other heating side plate 2 through the tightener 4, and at the same time, the stud connecting section 314 is screwed into the second threaded hole 323 to thread the bolt column 31 and the threaded nut, so that the two heating side plates 2 are fixed to each other, thereby reducing the force on the heating core 1 and making the heating core 1 less likely to be damaged.

[0034] This specific embodiment is merely an explanation of the present application and is not a limitation of the present application. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but as long as they are within the scope of the claims of the present application, they are protected by the patent law.
