[0017] 1. The user can place two welded profiles in two clamping components respectively, and start the main cylinder to fix the two profiles respectively. Fig.13 As shown, the two profiles are then brought close to each other and butted together through the butt assembly, the weld groove piece 1 and the weld groove piece 2 are driven to corresponding positions and the upper transport track and the lower transport track are brought close to each other, so that the two grinding heads are moved to a position in contact with the profile and the groove opening structure is started to grind and groove the side of the profile to be welded, and after the groove opening, the weld groove piece 1 and the weld groove piece 2 are moved to the placement area at the end of the upper transport track and the lower transport track so as not to affect the operation of the welding assembly 1 and the welding assembly 2, and then the welding assembly 1 and the welding assembly 2 are started to weld the top and bottom of the profile, wherein the welding assembly The first and second welding components are both segmented to weld the top and bottom of the profile, and the welding directions of the first and second welding components are opposite. After welding is completed, the second and first welding components are started again to grind the unwelded parts of the profile again. As shown, the first and second welding components are started again to weld the unwelded parts. The segmented welding and the simultaneous welding on both sides can reduce the generation of thermal deformation, improve efficiency and reduce the possibility of profile deformation. The simultaneous grooving and welding on the upper and lower sides can weld the thickened profile, which improves the firmness of the welding.

[0018] 2. If the length of the profile is greater than the length of the welding device and the first welding cannot be completed, when the profile needs to be transported, the user drives the electric push rod to make the linkage plate 1 and the linkage plate 2 close to each other, so that the upper and lower feed rollers clamp the upper and lower sides of the profile, and then drive the upper and lower feed rollers to rotate simultaneously through the motor, so that the profile is transported inward, and the welding part on the other side of the profile is welded, which improves the continuity of the device and the applicability to the extended mold steel;

[0019] 3. The upper connecting beam and the lower connecting beam are driven by the lifting slide rail, and the weld groove piece 1, the weld groove piece 2, the welding assembly 1 and the welding assembly 2 are all provided with a driving mechanism inside, which is used to drive the mechanism to slide inside the upper transport track or the lower transport track, wherein the weld groove piece 1 and the weld groove piece 2 are completed, so that the weld groove piece 1 is located in the placement area at the right end of the transport track, and the weld groove piece 2 is located in the placement area at the left end of the transport track, so as not to affect the operation of the welding assembly 1 and the welding assembly 2, wherein the bottom of the weld groove piece 2 and the top of the weld groove piece 1 are both provided with a sensing device and a distance measuring device, the sensing device is used to sense the distance between the two profiles to be welded, and the distance measuring device is used to detect the thickness of the profile, so as to detect whether the device is deformed and the degree of deformation, which is conducive to adjusting the length and position of the welding according to the degree of deformation, and by detecting the thickness of the profile, it is conducive to adjusting the depth of the groove;

[0020] 4. The universal wheel contacts the profile, and according to the height of the profile, the universal wheel pushes the connecting frame to move up and down. The connecting frame is driven by the fixed ring, and the grinding head slides up and down. The grinding head is slidably connected between the grinding head and the profile, thereby squeezing the second elastic member. The second elastic member pushes the grinding head to reset under the elastic action, which is conducive to free fine-tuning according to the concave and convex surface of the profile, which is conducive to expanding the applicability and preventing thermal deformation caused by different groove depths; the reserved block is slidably connected with the reserved groove, which is conducive to limiting the range of movement of the grinding head. The user adjusts the distance between the universal wheel and the profile by turning the knob, which is conducive to adaptive adjustment according to the thickness of the profile and expanding the scope of application of the device;

[0021] 5. Double-sided slotted welds and double-sided simultaneous welding are beneficial to reducing the occurrence of thermal deformation. The weld groove is set to 30°, and welds are set on both sides. The X-shaped symmetrical weld is beneficial to balancing the shrinkage force on the central axis of the joint, and the segmented welding is beneficial to controlling the length of the weld. The gap welding method is more conducive to reducing welding deformation, and welding on both sides at the same time is conducive to creating a force opposite to the deformation to balance the deformation force, and welding on both sides is conducive to improving the strength of the welding.

[0049] In actual operation, the user can place two welded profiles in the two clamping components 003 respectively, and start the main cylinder to fix the two profiles respectively. Fig.13 As shown in S1, the two profiles are then brought close to each other and butted together by the butt joint assembly 002, as shown in Fig.13 As shown in S2, by driving the weld groove opening member 1 005 and the weld groove opening member 2 006 to corresponding positions and by bringing the upper transport track 404 and the lower transport track 405 closer to each other, the two grinding heads 913 are moved to the position in contact with the profile and the groove opening structure 009 is started to grind and groove the side of the profile to be welded, as shown in FIG.

[0050] If the length of the profile is greater than the length of the welding device, after welding is completed, the user can release the clamping of the profile and drive the linkage plate on the side of the upper feeding roller 306 and the lower feeding roller 307, so that the upper feeding roller 306 and the lower feeding roller 307 approach each other to clamp the profile, and the motor drives the upper feeding roller 306 and the lower feeding roller 307 to rotate to convey the lengthened profile, so as to weld the next section of the profile, improving the connection continuity and applicability of the device, and being beneficial to the welding of lengthened die steel.
