Synchronizers are widely used in mechanical equipment, but due to different technical requirements or product structure requirements, the designed configuration structures of synchronizers are also different. For example, the patent publication number is CN101688567A, a synchronous device for a motor vehicle transmission, which has at least one synchronous ring and a paired cone, and the synchronous ring and the paired cone rotate at the same speed in the connected state, wherein A friction ring is arranged between the bodies, and the friction ring can move freely between the synchronous ring and the mating cone in an unconnected state and is loosely arranged between the synchronizing ring and the mating cone. Another example is a three-spindle synchronization device with the patent publication number CN101718285A, which is characterized in that sliding bearings are arranged at the corresponding positions of the front end cover and the rear end cover, and the two ends of the driving shaft and the driven shaft arranged in parallel are arranged in the inner hole of the sliding bearing Among them, three oil cavities and two partitions are fixed between the front end cover and the rear end cover. The partition is arranged between the two oil cavities, and an oil inlet is placed on the middle oil cavity. The other ends of each oil chamber are provided with oil outlets, the oil chambers pass through all oil chambers and baffles and communicate with the oil inlets, three driving wheels are arranged on the driving shaft, and three and Corresponding to the driven wheel meshed with the driving wheel, a pair of meshing gears are arranged in an oil chamber, and each oil chamber is provided with a high-pressure chamber and a low-pressure chamber. These existing technologies are all specific synchronizer structures, which cannot fulfill the synchronous requirements of multiple linear tubes required by the present invention.

The vertical support cooperates with the induction furnace in the production line for induction annealing of multiple linear tubes to ensure that the pipes output from the induction furnace can basically maintain a parallel height and pass through the synchronization device. Composed of rings, etc., the feature is that it relies on friction to achieve synchronization. There are locking angles on the adapter sleeve, synchronization lock ring and the ring gear of the gear to be engaged. The inner cone surface of the synchronization lock ring contacts the outer cone surface of the gear ring to be engaged. The friction, locking angle and cone surface have been properly selected in the design. The friction of the cone surface makes the tooth sleeve and the ring gear to be meshed quickly synchronized, and at the same time produces a locking effect to prevent the gears from meshing before synchronization. Install a broken pipe stop signal collection point on the synchronizer. One end of the signal line is connected to the synchronizer, and the other end is connected to the PLC power cat. The synchronizer is connected to the steel pipe to form a circuit loop. Under normal circumstances, its circuit is Access, when the steel pipe breaks, it is equivalent to an open circuit of the electrical appliance, and the PLC power cat sends an instruction to stop.

As a preference, the outer diameter of the synchronous wheel is provided with a pipe running groove, and the pipe running groove is consistent with the direction of the linear pipe. Multiple linear tubes are equipped with multiple tube slots, and each linear tube can be detected by the synchronizer at any time.

As a preference, a rocker seat is provided below the horizontal cantilever, and the upper end of the rocker arm is positioned in the rocker seat through a pivot pin, and the outer diameter of the pivot pin is in clearance fit with the pin hole at the upper end of the rocker arm. The rocker arm is connected to the synchronizer, and the shaft pin is used as the fulcrum to make a slight swing along the pipe running direction to obtain the pipe running information at any time.

Preferably, the lower end of the rocker arm is provided with an engaging sleeve, and the engaging sleeve cooperates with a synchronizing lock ring provided on the outer diameter of the synchronizer.
