Abstract
The utility model discloses a double-roller skew-rolling ingot metal cold perforating, enlarging hole machine, comprising a frame, two driving rotary type rollers on the frame, a hole perforating top rod arranged between two driving rotary type rollers, two driven rotary type rollers contacting with the workpiece to be process and arranged between two driving rotary type rollers. The double-roller skew-rolling ingot metal cold perforating, enlarging hole machine has features of reasonable structure, high process efficiency, small energy consumption, good product quality and no environment pollution and no need in additional heating device to realize the hole perforating, enlarging process during the rolling cold perforating, enlarging hole process.
Description
Technical field:
The utility model relates to a kind of metallurgy rolling equipment.
Background technology:
Oblique millings such as existing two rollers, three rollers are worn, staving press, when rolled steel tube, copper pipe, need to adopt the hot rolling method, promptly 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 purpose of this utility model be 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 utility model 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 utility model 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; The working (machining) efficiency height, 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 utility model is described in further detail below in conjunction with drawings and Examples.
Description of drawings:
Fig. 1 is the configuration diagram of an embodiment of the utility model.
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.Per pass surface recessed or prominent ring all is smooth form.
