[0057] This embodiment also provides a welding method based on the welding system 100 for the annular runner wax pattern, comprising the following steps:

[0058] Step 1: Set the annular runner 7 on the second support member, and place the wax mold 36 on the wax mold bracket according to actual needs.

[0059] Step 2: Adjust the linear telescopic drive component to drive the second support plate 24 to move, so that the heating component is located on the outside of the annular runner 7, and adjust the second elastic ejection mechanism through the second adjustment mechanism to drive the heating component to move inward, so that the heating component is in contact with the outside of the annular runner 7; specifically, turn the knob 35 to release the second traction rope 34, and at this time, under the action of the second spring 29, the second ejector rod 28 drives the heating component to move toward the annular runner 7, and then fits it.

[0060] Step three, after heating the heating component to the target temperature, adjust the first adjustment mechanism so that the first elastic ejection mechanism pushes the wax model 36 inward, so that the inner connecting surface of the wax model 36 contacts the heating component; specifically, take the paddle 22 out of the lower slot and move it to the upper slot, release the first traction rope 21, and at this time, under the action of the first spring 17, the first ejector rod 16 drives the block 18 to quickly push the wax model 36 inward, so that it contacts the heating component, and the heating component can be quickly heated.

[0061] Step 4: After holding for 5s to 10s, adjust the linear telescopic drive component to raise the second support plate 24, driving the heating component to quickly withdraw from the connection between the annular runner 7 and the wax mold 36. At this time, the wax mold 36 is connected to the annular runner 7 under the pressure of the first elastic ejection mechanism, that is, it is connected to the annular runner 7 under the elastic force of the first spring 17.

[0062] Step 5: After maintaining the above state for 5 to 10 minutes, adjust the first adjustment mechanism so that the first elastic ejection mechanism leaves the wax mold 36, and then take out the completed wax mold 36.

[0063] In this embodiment, a blade of a certain type is taken as an example, the diameter of the annular runner 7 is 200 mm, the thickness is 30 mm, the width of the wax mold 36 is 40 mm, and the number of the wax molds 36 is 15.

[0064] The completed wax model is taken out, and the size of the wax model is inspected after shell making → dewaxing → shell pre-baking → pouring → cutting → sandblasting.

[0065] Comparative example: The tree assembly process is entirely carried out manually, and the subsequent shell making to testing processes are consistent with those of this embodiment.

[0066] The wax molds welded by the above system and the wax molds welded by hand were selected to make castings respectively, and the torsion angles of different sections of the castings were measured. The positions of sections I and V are as follows: Figure 3 As shown, the dimensions of each casting in this embodiment are shown in Table 1, and the dimensions of each casting in the comparative example are shown in Table 2.

[0067] Table 1 Dimensions of each casting in this embodiment

[0068]

[0069] Table 2 Dimensions of castings in comparative examples

[0070]

[0071]

[0072] like Figure 4 As shown, by comparing the two, it can be seen that the consistency of Section I and Section V of the casting in this embodiment is higher than that of Section I and Section V of the casting in the comparative example.

[0073] It can be seen that in this embodiment, the first adjusting mechanism, the second adjusting mechanism, the linear telescopic drive component and the heating component are coordinated to realize the assembly welding of the annular runner wax mold, which can ensure the welding strength and weld consistency of the wax mold, prevent the deformation of the wax mold during manual welding, improve the qualified rate of castings, and improve the production efficiency of the assembly tree during continuous production.
