Rail, described feeding trolley both sides are provided with and roll, with bracket two side rails, some guide wheels being connected, and are arranged at pushing away of feeding trolley
Material bar front end has the rotation being connected with charging ram to cut somebody's hair, and cutting somebody's hair to be provided with and charging ram between in rotation can limit rotation and cut somebody's hair
The bolt of axial movement and axial thrust bearing.It is provided with the connection collectively constituting with plug supporting mechanism in feeding trolley rear end
Dynamic device, the elastic Zhuan Lun mechanism that linkage includes dolly rear end and the elastics wing machine being arranged on plug supporting mechanism
Structure, core rod support roller can be held up when advancing by feeding trolley, and knocks core rod support roller down when feeding trolley retreats.
But this blank feed mechanism has the following disadvantages in actual production：
A, dolly rotate the axial thrust bearing of setting and charging ram between of cutting somebody's hair and are limited by physical dimension, and specification is little, and
And rotate each rolling of cutting somebody's hair and will be affected by high temperature, the life-span of bearing is shorter near contact in rolling, bearing rotates failure
Afterwards, dry friction will be produced between push rod cup and pipe；
B, pipe supporting mechanism are arranged side by side on lathe bed bracket centrage by two cylindrical rolls, due to three-roller planetary tube rolling
Machine work characteristics, pipe is to be rotationally advancing under pusher dolly promotes at work, there is advance and slide between roll surface and pipe
, inevitably there is bowing phenomena, therefore deposit in resistance and the scuffing of outer surface of tube blank, and the elongated cantilever configuration of dolly charging ram
There is hard scuffing in charging ram and each pipe support roller, the pipe support roller being scratched surface will have a strong impact on product quality,
And increased the renewal cost of support roller part；
C, the elasticity of dolly hit wheel not high with the elastics wing mechanism reliability of plug supporting mechanism, there is plug and plug
The problem of support roller abrasion.And because plug supporting mechanism is fixed on the bracket of lathe bed, because core rod support roller is highly gone up
Non-adjustable, the plug rotating in the operation of rolling will be rubbed with core rod support roller surface, the metal fillings of the generation after abrasion
If entering into the product quality that will have a strong impact on subsequent processing in pipe.
Therefore, this blank feed mechanism has very big room for improvement.
