Detailed Description
The invention will be further elucidated in the following in accordance with the drawings.
As shown in fig. 1, the electric heating tube coiling and forming device comprises a driving wheel 3, a driven wheel 7 and a frame 9, wherein the driving wheel 3 and the driven wheel 7 are arranged on the frame 9 in parallel, a counter bore 5 is arranged in the center of the right end face of the driving wheel 3, a first shaft 8 is fixedly arranged on the left end face of the driving wheel 3, and the first shaft 8 is connected with a driving shaft of a motor 1; the driven wheel 7 is provided with a spiral groove 6, and the center of the driven wheel 7 is provided with a second shaft 10.
The edge of the right end face of the driving wheel 3 is also provided with a step gap 2 which is used as a spiral starting point when the electrothermal tube 4 is coiled.
The depth of the counter bore 5 is equal to the length of a straight pipe in the axial direction of the electric heating tube 4 after forming, and the diameter size of the counter bore 5 is matched with the size of a straight edge of the electric heating tube 4.
The first shaft 8 is fixed on the frame 9 through a bearing and a bearing seat.
The second shaft 10 extends out of the left end and the right end of the driven wheel 7, the driven wheel 7 is provided with a bearing and a bearing seat, the bearing seat is fixed on the frame 9, the driven wheel 7 can freely rotate around the second shaft 10 at the center of the driven wheel 7, and when the electric heating tube 4 is coiled in the spiral groove 6 of the electric heating tube, the driven wheel 7 can freely rotate under the action of friction force, so that the surface damage caused by scraping between the electric heating tube 4 and the spiral groove 6 can be reduced.
The pitch of the spiral groove 6 is equal to the pitch of the coiled electrothermal tube 4.
The utility model discloses a working process does:
before coiling the electric heating tube 4, inserting one end of the electric heating tube 4 into a counter bore 5 on the right end face of a driving wheel 7, bending the heating tube by about 100 degrees, leaning the part of the electric heating tube 4 exposed out of the counter bore 5 against a step gap 2 on the right side of the driving wheel 3, placing the rest part of the electric heating tube 4 into a spiral groove 6 on the rightmost side of a driven wheel 3, and then starting a motor 1 to drive the driving wheel 3 to rotate in the anticlockwise direction; keep that electrothermal tube 4 is located the spiral groove 6 of driven wheel 7 of passive clockwise rotation all the time for electrothermal tube 4 coils according to the clockwise on action wheel 3, and because the spacing of spiral groove 6, make electrothermal tube 4 coil according to the pitch that equals with spiral groove 6, coil the completion back when electrothermal tube 5, stop motor 1 drive, take out the spiral electrothermal tube 4 that coils from action wheel 3 from a left side to the right side.
