Therefore, the objective of the invention is to propose the making apparatus that a kind of relay advances straight tube, horizontal direction moulding and sends spiral coil, advance the method for straight tube to make it to avoid on product, to occur burning, super bag and fold phenomenon continuously with relay-type, send the uniformity that hot spiral coil finished product guarantees spiral coil pitch with level.
The making apparatus of a kind of relay propelling level shaping spiral coil that the present invention proposes comprises by the clamping device and the molding fetal that is arranged on the slideway termination that are arranged on movably on the slideway, described clamping device is two groups of A, B, be pushed into straight tube and alternately be clamped in one of described two stack clamping devices, the end that is arranged at slideway that described molding fetal is vertical; Bracket system is made up of with the rotating cylinder that be arranged in parallel of bearing supporting carriage and two, and described cylinder and molding fetal planar quadrature and in abutting connection with molding fetal is characterized in that described clamping device and oil cylinder join and moved by its driving.
Adopt the processing step of the spiral coil making apparatus of the present invention's proposition to comprise:
1, will be become the shaped steel straight tube place clamping device and clamped by a clamping device;
2, moving this clamping device is advanced to straight tube in the molding fetal;
3, straight tube is heated and is bent to spirality in molding fetal; It is characterized in that,
4, the helix tube of spirality is a support with the cylinder in the horizontally disposed bracket system that is orthogonal to molding fetal, relies on the shaping spiral coil to send as level from transferring to roll;
5, before the A clamping device that clamps straight tube arrives its stroke end during desired location, the B clamping device begins to move, and the steel straight tube is clamped, and when the A clamping device was reached home, the A clamping device unclamped and returns;
6, when the B clamping device arrived before its stroke end desired location, the A clamping device began to move, and the steel straight tube is clamped, when the B clamping device is reached home, the B clamping device unclamps and returns, and reciprocal like this replacing is advanced in the molding fetal steel pipe continuously;
7, repeat 5,6 steps, be shaped until spiral coil and finish.
Adopt the making apparatus of the spiral coil of the present invention's proposition, not only can omit the device of crane and so on, the restriction that the size of the spiral coil of doing is not risen by factory building yet, particularly because the spiral coil that is shaped is sent by level from molding fetal and by two cylinder rests, its pitch can be not inhomogeneous because of self gravitation, in addition, adopt two stack clamping devices alternately to clamp straight tube and send to make and advance straight tube to carry out continuously with relay-type, not not intermittently, thereby do not have because of heating the out-of-date burning that occurs, play bag, the fold phenomenon, the spiral coil product quality of cooling aftershaping is outstanding.
