盤(pán)式制動(dòng)器及制動(dòng)鉗的拉削加工

Processing of disc brake and brake caliper by broaching machine

盤(pán)式制動(dòng)器及制動(dòng)鉗的拉削是近期汽車工業(yè)發(fā)展的結(jié)果，引導(dǎo)我們進(jìn)入該類零件的加工領(lǐng)域。對(duì)盤(pán)式制動(dòng)器來(lái)講相對(duì)較易加工，而制動(dòng)鉗由于本身的結(jié)構(gòu)剛性差，易變形。因此，我們采用了各項(xiàng)措施：在拉削過(guò)程中，我們采用了不同的速度。粗、精拉削齒升量合理安排。

為了保證精度不受零件變形影響，在機(jī)床加工過(guò)程中，粗、精加工分段拉削。夾具增加輔支撐，減少零件變形。我們?yōu)榇松a(chǎn)的平面外拉床，其主要參數(shù)為：

額定拉力：200KN

額定行程：1600mm-2500mm

Processing of disc brake and brake caliper by broaching machine Development of auto in recent period leads us into the field of disc brake and brake caliper broaching.Broaching disc brake is easy, but the bad rigidity and deformation of brake caliper makes us adopt measures:

We adopt different speed when broaching for the purpose of getting reasonable arrangement of rise teeth of rough broaching and finish broaching.

In order to guarantee the accuracy not affected by deformation of parts, finish broaching and rough broaching is individually. Additionally sup-port of jigs will reduce deformation.

The main specification of external surface broaching machine.

as follows:

Rated pulling capacity: 200kN

Nominal stroke:1600mm-2500mm
