What are the installation requirements of the pinion gear of the CNC shearing machine?

The structure of CNC shears is relatively simple, the technical content is not high, and the numerical control is easy to realize. The annual output of my country’s shears is about 7,000, and hydraulic shears account for more than 80%; the annual output of CNC shears is about 3,000; The ratio of vertical shears and swing shears is about 1:2, and this ratio is increasing year by year.

What are the installation requirements of the pinion gear of the CNC shearing machine? How to check the accuracy of the high-precision shearing machine?

CNC Shearing Machine

The domestically-made shearing machine can fully meet the domestic demand and has achieved a large number of exports. Domestic plate shears can cut carbon steel plates up to 30mm in thickness and 12m in length. There is a clear trend for CNC guillotine shears to eliminate CNC pendulum shears.

Technical requirements for pinion installation of Anhui Yongya CNC shearing machine:

(1) The axis of the pinion shaft is parallel to the axis of the plate bending machine, the level of the pinion shaft is 0.04mm/m, and the elevation difference is not more than ±1mm.

(2) The side clearance of large and small gear pairs can be implemented according to actual elections when there is no requirement in the drawings.

(3) The large and small gear pairs are meshed and colored, and check their contact spots: not less than 40% along the tooth height; not less than 70% along the tooth length, and in the middle of the tooth width.

(4) The coaxiality between the pinion shaft and the reducer shaft is 0.2mm.

(5) The coaxiality between the input shaft of the reducer and the motor shaft, and the output shaft of the auxiliary reducer is 0.2mm; the coaxiality between the input shaft of the auxiliary reducer and the auxiliary motor shaft is 0.2mm.

The shearing center with a large right-angle shearing machine as the main machine to meet the requirements of the plate distribution center is one of the development directions of CNC shears.

Hydraulic shearing machine is different from manual shearing machine. It mainly eliminates vibration stress through hydraulic components, so that the accuracy of the components is more accurate.

High-precision shears generally we need to check the following aspects:

Is the hydraulic system of the hydraulic shearing machine working in a normal state; is there any abnormality in the hydraulic pump;

The last time the hydraulic oil was checked for cleanliness and the result of the cleaning and replacement of the filter element; if there is a failure, whether some hydraulic components have been adjusted before the failure, and what are the abnormalities of the shears before and after the failure; the previous shears What faults have occurred on the machine and how to solve them.
