Description
Technical field
The present invention relates to feeding device technical field, more specifically to a kind of feeding device for milling train.
Background technology
, it is necessary to have pipe feed mechanism and plug feed mechanism during three-roller planetary pipe mill drawn and rolled tube.How 20 meters are made
The rolling campaign of the pipe matching three-roller planetary pipe mill of left and right, ensures the even running of rolling process, is metal pipe material processing
Important step.
Chinese patent《A kind of blank feed mechanism of pipe bar rolling mill》(notification number：CN2688406Y the feeding dress involved by)
Put including feeding lathe bed, be arranged at the plug feed mechanism of feeding lathe bed afterbody, being arranged on feeding lathe bed charging ram is housed
Feeding trolley and be arranged on the outside of feeding lathe bed drive feeding trolley work sprocket transmission device.There is support on lathe bed
Groove, it is transversely provided with along bracket by spaced some pipe supporting mechanisms and plug supporting mechanism, is provided with and leads in bracket both sides
Rail, described feeding trolley both sides are provided with some guide wheels that connection is rolled with the side rails of bracket two, are arranged at pushing away for feeding trolley
Material bar front end has the rotation being connected with charging ram to cut somebody's hair, and rotation can be limited and cut somebody's hair by cutting somebody's hair to be provided between charging ram in rotation
The bolt and axial thrust bearing of axial movement.The connection collectively constituted with plug supporting mechanism is provided with feeding trolley rear end
Dynamic device, the elastics wing machine that linkage includes the elastic Zhuan Lun mechanisms of dolly rear end and is arranged on plug supporting mechanism
Structure, feeding trolley can hold up core rod support roller when advancing, and knock core rod support roller down when feeding trolley retreats.
But the blank feed mechanism has the following disadvantages in actual production：
A, dolly rotates the axial thrust bearing set between charging ram of cutting somebody's hair and limited by physical dimension, and specification is small, and
And rotation is cut somebody's hair and rolls will be influenceed close to contact in rolling by high temperature every time, the life-span of bearing is shorter, and bearing rotates failure
Afterwards, dry friction will be produced between push rod cup and pipe；
B, pipe supporting mechanism is arranged side by side on lathe bed bracket center line by two cylindrical rolls, due to three-roller planetary tube rolling
Machine work characteristics, pipe are rotationally advancing under the promotion of pusher dolly at work, are slided between roll surface and pipe in the presence of advance
, bowing phenomena inevitably be present, therefore deposit in the scuffing of resistance and outer surface of tube blank, and the elongated cantilever configuration of dolly charging ram
Hard scuffing being present in charging ram and each pipe support roller, product quality will be had a strong impact on by being scratched the pipe support roller on surface,
And add the renewal cost of support roller part；
C, the elasticity of dolly hit wheel it is not high with the elastics wing mechanism reliability of plug supporting mechanism, plug and plug be present
The problem of support roller is worn.And because plug supporting mechanism is fixed on the bracket of lathe bed, due in core rod support roller height
Non-adjustable, the plug rotated in the operation of rolling will rub with core rod support roller surface, the caused metal fillings after abrasion
If the product quality of subsequent processing will be had a strong impact on by entering in pipe.
Therefore, the blank feed mechanism has very big room for improvement.
