[0032] The plate-pulling die section includes a plate-pulling die box 11 and a guide frame 12 threadedly connected to the middle of the plate-pulling die box 11;

[0033] The plate-drawing die box 11 is used for drawing the copper tube, and the guide frame 12 is used for guiding the copper tube drawing;

[0034] The middle of the plate-pulling mold box 11 is a cavity opened, and the cavity is U-shaped;

[0035] The cavity is used to receive and install the guide frame 12, and the U-shaped setting is conducive to the drawing of the copper tube;

[0036] The middle part of the guide frame 12 is a guide opening that penetrates through the plate-pulling mold box 11;

[0037] The guide port is used to guide the copper tube during drawing;

[0038] The plate-pulling die section also includes a guide frame 13 extending through a corner of the front side of the plate-pulling die box 11 and a control frame 14 whose end is fixedly connected to an end above the guide frame 12;

[0039] The guide frame 13 guides and guides the liquid for centralized collection, and the control frame 14 applies the required force when the guide frame 12 is disassembled and moved;

[0040] The locking part includes a bracket 21 threadedly connected to the middle section of one side of the upper end of the guide frame 12, a vertical cylinder 1 22 penetrating and connected to one end of the upper part of the bracket 21, and a vertical cylinder 2 23 penetrating and connected to the other end of the upper part of the bracket 21;

[0041] The bracket 21 carries out structural installation of the vertical cylinder 1 22 and the vertical cylinder 2 23. Through the controlled vertical cylinder 1 22 and the vertical cylinder 2 23, the structure of the plate-drawing die box 11 can be positioned after it swings left and right to form a straight line with the copper tube and reaches the drawing position;

[0042] The input ends of the vertical cylinder 1 22 and the vertical cylinder 2 23 are sleeve holes, and the sleeve holes are sleeve-connected to the output ends of the external air supply equipment through pipelines;

[0043] The sleeve hole is connected to one end of the pipeline, and the other end of the pipeline is connected to an external air supply device to provide the power required by the vertical cylinder 1 22 and the vertical cylinder 2 23;

[0044] A straightening unit, the straightening unit includes a mounting frame 31 arranged on one side of the disc drawing die box 11;

[0045] The installation frame 31 provides an installation environment for the structure to be installed;

[0046] The straightening part also includes five shafts 32 rotatably connected to the bottom end of the mounting frame 31, straightening rollers 33 sleeved and fixedly connected to the lower part of the shafts 32, a connecting frame 34 fixedly connected to one end of the mounting frame 31, a support 35 whose end is fixedly connected to one end of the upper part of the connecting frame 34, and a disc pulling roller 36 rotatably connected to the middle part of the support 35;

[0047] The shaft 32 carries out structural support for the straightening roller 33, and the straightening roller 33 is used to straighten the drawn copper tube. The connecting frame 34 carries out structural installation for the support 35, and is used to carry out structural rotation support for the disk-pulling roller 36, and the disk-pulling roller 36 carries out one end of the drawn copper tube.

[0048] The upper part of the shaft 32 is equidistantly threadedly connected with a limit stud 37, and the screw head of the limit stud 37 is hexagonal;

[0049] The limiting stud 37 limits the structure of the straightening roller 33 at the bottom, and the hexagonal shape of the screw head increases the difficulty of disassembling and assembling the limiting stud 37, which has a certain anti-theft effect;

[0050] Three shafts 32 are rotatably connected to the rear of the bottom end of the mounting frame 31, and one group of shafts 32 is rotatably connected to the front of the bottom end of the mounting frame 31;

[0052] The staggered arrangement between the shafts 32 is conducive to receiving the copper tube in drawing and improving the straightening effect;

[0053] Working principle:

[0054] In advance, the guide frame 12 is structurally controlled by the control frame 14 and placed in the cavity of the plate drawing mold box 11 for thread locking;

[0055] Next, three and two shafts 32 are staggered and rotated to connect the front and rear of the bottom end of the installation frame 31, and the straightening roller 33 is sleeved and fixed to the lower part of the shaft 32, and the limit studs 37 are equidistantly arranged on the upper part of the shaft 32, and the pull roller 36 is installed on the upper part of the connecting frame 34 through the support 35;

[0056] At this time, when the copper tube is pulled by the coil-pulling die box 11 in cooperation with the guide frame 12, the coil-pulling die box 11 is separately arranged from the mounting frame 31, and is affected by the copper tube pulling force to drive the coil-pulling die box 11 to swing left and right, so that the copper tube and the coil-pulling die box 11 are always in a straight line, and after reaching the drawing position, the coil-pulling die box 11 can be locked by the controlled vertical cylinder 1 22 and the vertical cylinder 2 23, and the copper tube subsequently drawn out can be straightened by the straightening roller 33;

[0057] This step ensures that the drawn copper tube is evenly stressed, achieves linear stretching, reduces the probability of tube breakage, improves operating efficiency, increases the yield rate, and saves costs.
