Detailed ways

The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. However, it should be noted that the description of the following embodiments is schematic and does not constitute a specific limitation to the present invention.

Referring to Fig. 1 and Fig. 2, a kind of heating roll forming equipment of the present invention comprises: a heating device 10 and a roll forming device 20, and the roll forming device 20 includes a machine table 21, and a rotating machine set on the machine table 21 The turntable 22 and the driving device 23 that drives the turntable 22 to rotate, the circumferential side wall of the turntable 22 is provided with a spiral forming groove 221 for acrylic pipe rolling and forming, and the machine table 21 is provided with a limiter located on the outer periphery of the turntable 22 Position guide mechanism 24, the limit guide mechanism 24 is connected with a driver 25 that drives it close to or away from the forming groove 221, the limit guide mechanism 24 is close to the forming groove 221 to form a forming space for the acrylic pipe to be rolled into a circle, The limit guide mechanism 24 is close to the forming groove to abut against the acrylic pipe. The forming space formed by the limit guide mechanism 24 and the forming groove 221 is adapted to the cross-sectional shape of the acrylic pipe. During the rolling forming process of the acrylic pipe, Constrained by the forming groove and the runner, the shape is gradually formed. The number of turns of the forming groove 221 is one turn, and its pitch matches the outer diameter of the acrylic pipe; the heating and rolling equipment with the above structure drives the turntable 22 to rotate and cooperate with the limit The guide mechanism 24 forms a spiral acrylic pipe, which prevents the thinner acrylic pipe from being easily deformed when it is rolled, and ensures the roundness and shape and size requirements of the acrylic pipe. The spiral acrylic pipe formed by this equipment only needs to be cut off The part beyond the full circle can form an acrylic tube with higher roundness.
