Definitions

  • This invention relates to a device for shaping a belt of a welding machine, and more particularly to a stable welding device designed for a splicing joint.
  • the shaping process of the strip welding machine strip is to gradually deform the strip material to the longitudinal seam tube through a plurality of sets of vertical rollers and horizontal rollers, and then control the stability of the weld seam through a set of horizontal rollers.
  • This set of stable quilting rollers mainly controls the center position of the longitudinal seam after the shaping and the size and yaw of the weld.
  • the problem with this roller control method is that all the roller sets cannot be made very accurately. The combination of the roller and the shaft and the bearing is good, and there will be a gap. Naturally, the accumulated error after assembly will be formed.
  • the process of forming the longitudinal seam tube by the shaping roller is firstly crimping from both sides of the strip, and then the basic arc edge is multi-staged to the longitudinal seam tube. After winding into a longitudinal seam pipe, on the circumferential distribution of the longitudinal seam pipe, the rollers of each stage wind up the arc transition point, and a certain stress is generated. The stress distribution on the circumferential distribution of the pipe is uneven, when welding the longitudinal seam When the high temperature longitudinal tube is generated, it absorbs heat. It is said that the internal stress formed by the longitudinal joint is subjected to stress after being heated, which in turn causes a second factor of instability of the weld.
  • the present invention provides a stable welding device by a large number of tests and continuous exploration, which solves the problem of instability in the prior art, and
  • the roundness error of the tube after the coiling tube is eliminated; the uniform distribution of the circumferential distribution stress of the tube and the straightness of the longitudinal joint tube are ensured.
  • the technical solution of the present invention is as follows - a plastic mold is disposed at both ends of the base bracket, and a guide tab bracket is mounted on one side of the base bracket, and the guide tab is mounted on the elastic port of the guide bracket.
  • the two molds are disposed on the same center line in the base bracket.
  • the guide piece is inserted into the longitudinal slit with a guiding angle.
  • the guiding portion of the guiding piece is on the same straight line as the shaping die.
  • the strip is introduced into the stable welding device through a plurality of sets of coiled tubes, and the wrapped metal rod is inserted into the longitudinal seam tube.
  • the longitudinal slit drives the rod to travel synchronously, and the guide piece of a certain depth in the longitudinal slit has a certain guiding angle guide.
  • a centrally positioned longitudinal seam tube shaping mold is arranged, and the centering shaping mold is used to control the correction of the out-of-roundness of the longitudinal slit.
  • the biggest advantage of using a plastic mold to stabilize the weld is that there is no variable factor; insert the guide piece into the weld to a certain depth to control the yaw of the weld, correct the shaping roll, and there is almost no gap between the longitudinal pipe and the die.
  • the clamping of the guide piece is clamped by the elastic port on the guide piece bracket, and there is no movable gap. Therefore, the present invention passes the two-way control, and the quilting of the longitudinal seam tube is stabilized at the center splicing position, so that The inventive device is fully suitable for fistula and cladding welding.
  • FIG. 1 is a schematic front view showing the structure of the present invention.
  • Figure 2 is a schematic side view of the structure of the present invention.
  • Figure 3 is a schematic view of the A-direction structure of the present invention.
  • the base bracket 7 is fixed by the hexagonal screw 6 at the wrapping machine welding gun 17; the two ends of the base bracket 7 are provided with a shaping die 2 on the same center line, and one of the base brackets 7
  • the guide piece bracket 5 is mounted on the side by the hexagon socket screw 9, and the guide piece 3 is clamped by the hexagon socket screw 4 on the elastic port of the guide piece bracket 5, and the depth of the guide piece 3 in the longitudinal seam tube can be adjusted by the elastic hexagon socket screw 4;
  • the sheet 3 is inserted into the longitudinal slit with a guiding angle; the guiding portion of the guiding sheet 3 is on the same line as the shaping mold 2; the longitudinal seam tube 1 with the coated metal rod 8 passes through the front plurality of coiled tubes
  • the forming roller passes through the shaping die 2 and the guide piece 3 after shaping.
