Pipe tube straightener and cutting machine for A chipless 3-16mm
Straightener: a device involved in straightening the wire before it is processed is the last piece of the finished wire. It acts as a straightener, but its role is not only straightening the wire.
Straightener: A device for straightening steel wire before it is processed. Heating and straightening can meet the requirements. Straightening is the process of plastic deformation. The straightener on the laminar generally has 7 rounds or 9 rounds. Each three wheels can be seen as two edges with sloping plates. The longitudinal section shape of the static rubbing plate, its groove depth is from the depth to shallow and finally disappeared. Its working principle is that the pressure drop gradually decreases, so it can also be adjusted very straight. Its disadvantage is the reciprocating movement of the rubbing board, there is a blank course, and the production efficiency is not high enough. Although it is possible to use the emergency effect of the biased crank slider mechanism shown to reduce the space loss, due to the high quality of the moving rubbing board and the reciprocating motion, the inertial force generated by it is not easy to balance, which limits the improvement of the machine's operating speed. Therefore, productivity is still not ideal.
2) Planetary roll straight. The straightening machine's moving plate becomes a roller, which makes a continuous rotation movement. The static plate becomes an arc member, and the upper slot is also shallower and eventually disappears. This scheme not only corrects the rods very straight, but also has a high degree of automation and productivity.
3) Roll the rod with a flat press. The advantage of this method is that it is simple and easy to use. The disadvantage is that the material is not straight because of the rebound of the material.
4) Roll the bar with a slot press. Taking into account that "correction must be too positive", the static rubbing board is made into a shape with a slot, and the cross section of the moving and static rubbing board is made. In this way, it is possible to straighten the bending rods, but it is also possible to bend the straight rods. It is not ideal.
5) Straighten with a pressure bar. A similar mechanical device is designed. The straightening machine passes through an electric motor. On the one hand, the rod material is rotated. On the other hand, the pressure drop of the pressure rod is gradually reduced through the cam to achieve the purpose of straightening. Its advantage is that the rods can be adjusted very straight; The disadvantage is low productivity, loading and unloading rods need to stop.
