This series of broaching machine is vertical internal broaching machine in a structure of semi-protection and full escort, and auxiliary sliding plates of the broaching machine are installed on main sliding plates. During operation of the broaching machine, the tool clamping devices on main and auxiliary sliding plates effectively support front and rear tool holders of broaches simultaneously to guarantee broaches are stationary and displacement is not produced on both ends during operation. The workpieces to be machined are fixed on worktable after self-centering, broaches move downward, and after broaching the broaching machine unloads materials and returns. Full-escort broaching mode effectively guarantees accuracy and stability of the machined parts. This broaching machine is installed on the ground or embedded underground.
This series of broaching machine is applicable to machining of various types of internal teeth, internal splines and inner geometric holes. The broaching machine is driven hydraulically and its speed is stepless regulated on HMI. The broaching machine works in three operating modes, namely full-automatic circulation, semi-automatic segmentation and manual adjustment. The broaching machine is provided with the automatic toolsetting function. The machine has the automatic toolsetting function.
The broaching machine can be equipped with automatic loading and unloading devices optionally (truss manipulator or joint robot) so as to reduce the labor intensity of operators greatly and improve the machining quality of parts.
On basis of the actual specific requirements, customers can choose machine tools with multi-station mechanism. The user determines the selectable range according to the measured broaching force.
