[0002] At present, the development trend of the world wire products industry is heavy raw material discs, continuous, high-speed and automated production. my country's wire products industry has also begun to develop in this direction. As one of the important equipment in the wire products industry, the traction machine is mainly used in wire tensioning. During the straightening process, the steel wire is pulled through the straightening machine by the traction machine for straightening.

However, during the processing of the spring, the spring wire needs to be cut instantly and a processing pause time is required. In the prior art, a reducer is generally required to slow down the motor, so the energy consumption is relatively high. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the prior art, the purpose of the utility model is to provide an instantaneous stopping device for a spring wire traction machine, which is used to solve the problem in the prior art that the spring wire cannot be stopped instantly during the traction process.

[0005] In order to achieve the above purpose and other related purposes, the utility model provides the following technical solutions:

When the first traction wheel and the second traction wheel are approaching each other, the first traction wheel and the second traction wheel can jointly frictionally stop the spring steel wire. When the first traction wheel and the second traction wheel are moving away from each other, the first traction wheel and the second traction wheel stop frictionally stopping the spring steel wire. In the present application, the spring steel wire can be stopped instantly by the driving device, and the use of the reducer can be reduced.

[0008] In an embodiment of the present invention, a first driving component for driving the first traction wheel to rotate is disposed on the first hinged plate; and a second driving component for driving the second traction wheel to rotate is disposed on the second hinged plate.

[0014] In one embodiment of the present invention, the second driving assembly includes a second driving pulley and a second driven pulley connecting the two second traction wheels, a second driving belt sleeved between the second driving pulley and the second driven pulley, and a second driving motor that drives the second driving pulley to rotate.

[0015] To implement the above technical solution, the second drive motor can drive the second active pulley to rotate. Since the second drive belt is sleeved between the second active pulley and the second driven pulley, the two second traction wheels can rotate synchronously.

[0016] In one embodiment of the utility model, a first connecting rod is connected between the first traction wheel and the first driving pulley and the first driven pulley; a second connecting rod is connected between the second traction wheel and the second driving pulley and the second driven pulley; and two arc grooves for the first connecting rod and the second connecting rod to pass through are symmetrically provided on the back plate.

[0017] To implement the above technical solution, the driving device causes the first connecting rod and the second connecting rod to rotate, so an arc groove is opened on the back plate along the movement trajectory of the first connecting rod and the second connecting rod.

[0018] In an embodiment of the present invention, a plurality of traction grooves are disposed on the first traction wheel and the second traction wheel.

[0019] By implementing the above technical solution, multiple spring steel wires can be synchronously stopped by setting multiple traction grooves, thereby improving the stopping efficiency and the output of spring processing.

[0020] As described above, the utility model provides an instantaneous stopping device for a spring steel wire traction machine, which has the following beneficial effects: the driving device described in the present application can drive the first traction wheel and the second traction wheel to approach or move away from each other, and when the first traction wheel and the second traction wheel are close to each other, the first traction wheel and the second traction wheel can jointly rub and pull the spring steel wire, thereby stopping the spring steel wire instantaneously, and when the first traction wheel and the second traction wheel are away from each other, the first traction wheel and the second traction wheel stop rubbing and stopping the spring steel wire. In the present application, the driving device can stop the spring steel wire instantaneously without causing indentations or deformation on the surface of the spring steel wire, thereby improving the quality of spring forming.
