Abstract
The invention discloses a two-roller skew-rolling cold piercing and cold broaching machine for a metal ingot. The two-roller skew-rolling cold piercing and cold broaching machine is provided with a stand, two active-rotating type rollers are arranged on the stand, a pierced push rod is arranged between the two rollers, and two passive-rotating type rollers which are in contact with a machined workpiece are arranged between the two active-rotating type rollers. The invention can realize the piercing and broaching machining to the workpiece without additional heating devices for heating in the piercing and cold broaching process of workpiece rolling, and has reasonable structure, high machining efficiency, low energy consumption, good produced product quality and no environment pollution.
Description
Technical field:
The present invention relates to a kind of metallurgy rolling equipment.
Background technology:
Existing two rollers, roller trio skew rolling are worn, staving press, when rolled steel tube, copper pipe, need to adopt the hot rolling method; Be that strand needs with the firing equipment heating, roll preceding, roll the back and produce a large amount of scale losses, the rolled piece surface quality is poor; Equipment investment is big, and energy consumption is big, and exists labor strength big; Environmental pollution is big, and equipment is regulated defectives such as trouble.
Summary of the invention:
The object of the present invention is to provide a kind of workpiece rolling wear or the reaming process in, need not the heating of other heater, can realize workpiece is worn or the two-roller skew-rolling ingot of reaming processing is coldly worn, cold broaching machine.
Technical solution of the present invention is:
A kind of two-roller skew-rolling ingot is cold to be worn, cold broaching machine; Organic frame; It is characterized in that: adorn two active rotation formula rolls on the frame, the push rod of perforation is arranged in the middle of two rolls, and two passive rotary rolls that contact with workpiece to be machined are set between two active rotation formula rolls.
The moving rotary roll center of two active rotation formula rolls and two velamens symmetry.Two active rotation formula rolls adopt the form of sleeve roll.Two adjustable forms of active rotation formula roll and two velamens moving rotary roll employing draught pressure angle.Two active rotation formula roller surfaces are provided with recessed, the prominent ring structure of multiple tracks.Per pass surface recessed or prominent ring all is smooth form.
The present invention is rational in infrastructure, workpiece is rolling wear or the reaming process in, need not other heater heating, can realize workpiece is worn or reaming processing; Working (machining) efficiency is high, and energy consumption is little, particularly when recessed, the prominent ring structure of the multiple tracks that has roller surface, in process, make metal produce very big temperature rise, thereby resistance of deformation is little, realizes the effect with cold rolling method acquisition hot rolling; The product specification wide coverage of producing; The good product quality of producing, wall thickness is even, dense structure, crystal is tiny evenly, the bright and clean non-scale of surfaces externally and internally; Equipment volume is little, and small investment is good in economic efficiency; Non-environmental-pollution.The product of producing can omit operation such as pickling before road, the back drawing procedure or heat-treatment of annealing in the conventional processing.
The present invention is the further improvement on zl200510064481.3 patent basis, more reasonable structure, and result of use is better.
Below in conjunction with accompanying drawing and embodiment the present invention is described further.
Fig. 1 is the configuration diagram of one embodiment of the invention.
The specific embodiment:
A kind of two-roller skew-rolling ingot is cold to be worn, cold broaching machine; Organic frame 1; Adorn two active rotation formula rolls 2,3 on the frame, the push rod of perforation is arranged in the middle of two rolls, and two passive rotary rolls 4,5 that contact with workpiece to be machined are set between two active rotation formula rolls.The moving rotary roll center of two active rotation formula rolls and two velamens symmetry.Two active rotation formula rolls adopt the form of sleeve roll.Two active rotation formula rolls adopt the adjustable form in draught pressure angle.Two active rotation formula roller surfaces are provided with recessed, the prominent ring structure of multiple tracks, make to form the large deformation district between two active rotation formula rolls, and per pass surface recessed or prominent ring all is smooth form.
