LQ200 CNC Spline Cold Knocking Machine is mainly used for cold forming processing of large-size splines of shafts and discs. Such as: automotive transmission shaft spline, automotive axle spline, automotive gearbox clutch hub spline and so on. Strong rigidity, high precision, high degree of automation, mainly has the following technical characteristics:

1. The electric control system adopts Siemens high-end numerical control system and field bus connection.

2. Servo feed drive can be used for spline incremental processing.

3, using a dedicated high-speed intermittent indexing mechanism, with direct indexing and indirect indexing function, broaden the range of processing spline teeth.

4, using a special oil processing system, can achieve cooling lubricant material multi-stage filtration, temperature control, pressure control.

5. Automatic loading and unloading mechanism can be configured according to requirements, which can significantly increase production efficiency.

Processing principle

Cold tap forming is the use of metal shaping, using two high-speed rotation, and the roller profile is consistent with the roller hit the workpiece, the workpiece in addition to doing a rotary motion, but also for the axial feed movement, rolling out a long tooth.

Spline cold knocking

Development process

In 1968, it took the lead in the development of the spline cold knocking machine in China and successfully launched the QD-006 spline cold knocking machine for the machining of splined spline on automotive drive shafts.

In 1974, QD-014 spline cold knocking was completed and successfully marketed.

In 2010, completed the development of a new structure of CNC LQ200 spline cold knocking machine, which is used for the processing of clutch gear teeth in automotive gearboxes.

In 2015, he presided over the development of the "JB/T12298-2015 CNC spline cold knocking machine" industry standard.
