Description

Technical Field

[0001] The invention relates to the technical field of welding processing, in particular to a welding device and a welding method for a saw blade and a cutter head. Background Art

[0002] The tool is a tool used for cutting in mechanical manufacturing. The tool is generally made of high-temperature resistant cemented carbide material. However, since high-temperature resistant cemented carbide material is relatively expensive, in order to reduce costs, the tool head is made of high-temperature resistant hard material, and the tool handle is made of ordinary metal material. Therefore, the tool head and the handle need to be welded together. The existing welding method is through manual welding. There are some problems with manual welding. For example, since the tool head has a very high temperature resistance, the tool head and the handle are not easy to weld. After the tool head and the handle are welded, the temperature of the tool head and the handle drops sharply, and there is residual stress at the welding point. The welding point is prone to deformation or cracking. At the same time, due to the small size of the tool head and the handle, it is not easy to fix during welding, the welding efficiency is low, and the labor intensity is high.

Since the welding temperature of the saw blade 15 and the cutter head 16 is very high during the welding process, the saw blade 15 and the cutter head 16 are taken away by the manipulator 45 and placed in the finished product receiving bin 11, and the saw blade 15 and the cutter head 16 are cooled in the finished product receiving bin 11 to prevent burns.

The laser welding head 20 can move in the X-axis, Y-axis and Z-axis directions, which is convenient for welding saw blades 15 and cutter heads 16 of different widths and lengths.

[0047] like Figure 1 , Figures 8 to 12As shown, the welding equipment for the saw blade and the cutter head also includes a ninth driving unit 13, a second X-axis slide rail 14 is provided on the upper surface of the frame 10 along the length direction of the frame 10, and the high-frequency heating device 70 is slidably connected to the second X-axis slide rail 14. The ninth driving unit 13 drives the high-frequency heating device 70 to slide along the second X-axis slide rail 14. When the ninth driving unit 13 drives the high-frequency heating device 70 to slide close to the cutter head clamping device 90 or the saw blade clamping device 80, the high-frequency heating device 70 heats the connection between the saw blade 15 and the cutter head 16 and tempers the welding joint between the saw blade 15 and the cutter head 16 after welding. Specifically, when the ninth driving unit 13 drives the high-frequency heating device 70 to slide along the second X-axis slide rail 14 toward the tool head clamping device 90, the heating head of the high-frequency heating device 70 heats the connection between the saw blade 15 and the tool head 16. After the heating is completed, the ninth driving unit 13 drives the high-frequency heating device 70 to slide along the second X-axis slide rail 14 away from the tool head clamping device 90, and at the same time, the laser welding head 20 welds the connection between the saw blade 15 and the tool head 16. After the welding is completed, the ninth driving unit 13 drives the high-frequency heating device 70 to heat the connection between the saw blade 15 and the tool head 16. 0 slides along the second X-axis slide rail 14 toward the tool head clamping device 90, and the heating head of the high-frequency heating device 70 tempers the welding place of the saw blade 15 and the tool head 16. After the tempering is completed, the pusher device 40 slides along the frame 10 toward the tool head clamping device 90, and the manipulator 45 clamps the welded saw blade 15 and the tool head 16. At the same time, the pusher 43 pushes the saw blade 15 in the saw blade storage device 50 to move to the saw blade clamping device 80, and the pusher bar 44 pushes the tool head 16 in the tool head feeding device 60 to the tool head clamping device 90. The heating head of the high-frequency heating device 70 heats the connection between the saw blade 15 and the tool head 16, thereby improving the welding efficiency; the heating head of the high-frequency heating device 70 tempers the welding place of the saw blade 15 and the tool head 16, thereby changing the internal structure of the welding place of the saw blade 15 and the tool head 16, thereby making the welding place of the saw blade 15 and the tool head 16 more firmly welded. The tempering of the high-frequency heating device 70 improves the cutting processability of the cutter head 16, reduces the residual stress in the cutter head 16 and the saw blade 15, stabilizes the dimensions of the cutter head 16 and the saw blade 15, and reduces the deformation and crack tendency of the cutter head 16 and the saw blade 15; the welding of the cutter head 16 and the saw blade 15 is automated, thereby improving efficiency.

[0048] The fourth embodiment, as Figures 1 to 13 As shown, the method of welding the saw blade 15 and the cutter head 16 by welding equipment includes:

[0049] In the first step, the pusher device 40 slides from the first end of the frame 10 to the second end close to the frame 10, and the pusher device 40 pushes the saw blade 15 in the saw blade 15 storage device 50 to move to the saw blade 15 clamping device 80, and at the same time, pushes the cutter head 16 in the cutter head 16 feeding device 60 to move to the cutter head 16 clamping device 90;

[0050] In the second step, the saw blade 15 clamping device 80 clamps the saw blade 15, and the cutter head 16 clamping device 90 clamps the cutter head 16;

[0051] In the third step, the clamping device 80 of the saw blade 15 is moved close to the clamping device 90 of the cutter head 16 so that the edge of the saw blade 15 butts against the edge of the cutter head 16;

[0052] Step 4: When the high-frequency heating device 70 slides from the second end of the frame 10 to the first end close to the frame 10 , the high-frequency heating device 70 heats the connection between the saw blade 15 and the cutter head 16 ;

[0053] In the fifth step, the laser welding head 20 welds the connection between the saw blade 15 and the cutter head 16 .

[0054] The fifth embodiment, as Figures 1 to 13 As shown, the difference between this embodiment and the fourth embodiment is that it also includes a sixth step, after the laser welding head 20 welds the connection between the saw blade 15 and the cutter head 16, the high-frequency heating device 70 tempers the welding point between the saw blade 15 and the cutter head 16.
