Abstract
The utility model discloses a three-roller cold penetrating hole enlarging machine for skew rolling, which is provided with a machine frame, wherein three rotary type rollers are arranged on the machine frame; a post rod of a rolled-piece piercing plug mechanism is arranged among the three rollers. The utility model has the advantage of reasonable structure; besides, in the process of the rolling and cold penetrating hole enlarging of workpieces, an additional heating device does not need heating, and the workpieces can be carried out for penetrating and hole enlarging for processing; the work efficiency is high; equipment obtains the large deformation of sigma which is larger than 80% to 95% one time; the utility model also has the advantages of low energy consumption, good production quality in production and no environment pollution.
Description
Technical field:
The utility model relates to a kind of metallurgy rolling equipment.
Background technology:
Existing roller trio skew rolling is 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 roller trio skew rolling of reaming processing is coldly worn, cold broaching machine.
Technical solution of the present utility model is:
A kind of roller trio skew rolling is cold to be worn, cold broaching machine, and organic frame is characterized in that: adorn three rotary rolls on the frame, the push rod of rolled piece top mechanism is arranged in the middle of three rolls.
Three roll axis fork 115～125 degree.Frame has fixed support, adorns rotatable adjustable type support in the fixed support, and rotatable adjustable type support is connected with roll.There is the push rod of the streamlined of being equipped with top in rolled piece top mechanism, and the push rod periphery is provided with the pressure roller clamping device.Three roller surfaces are provided with recessed, the prominent ring structure of multiple tracks.Per pass surface recessed or prominent ring all is smooth form.That certain three roller surfaces also can not established is recessed, prominent ring structure, is smooth arc surface.
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, an equipment once can obtain the large deformation of ∑＞80～95%; 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.
Fig. 1 is the configuration diagram of an embodiment of the utility model.
Fig. 2 is the diagrammatic sketch that is connected of roll and frame among Fig. 1.
Fig. 3 is a rolled piece top mechanism structure diagrammatic sketch.
The specific embodiment:
A kind of roller trio skew rolling is cold to be worn, cold broaching machine, and organic frame is adorned three rotary rolls 2 on the frame, and the push rod 8 of rolled piece top mechanism is arranged in the middle of three rolls 2, about three roll axis fork 115～125 degree.Frame has fixed support 1, adorns rotatable adjustable type support 6 in the fixed support 1, and rotatable adjustable type support 6 is connected with roll 2, can after fixing, realize the adjustment to three roll shop building distances as required by the position of the rotatable adjustable type support 6 of rotation during work.Rolled piece top mechanism has the push rod 8 of the streamlined of being equipped with top 5 to connect, push rod 8 peripheries are provided with packaged type cross roll clamping device, the cross roll clamping device comprises three cross rolls 9 that clamp push rod 8, cross roll 9 is connected with packaged type support 7, and push rod 8 moves along with moving of packaged type support 7 in the course of work.Three roller surfaces are provided with recessed, the prominent ring structure 3 of multiple tracks, and per pass surface recessed or prominent ring all is smooth form (certain three roller surfaces also can not established recessed, prominent ring structure, be smooth arc surface form).Also has rolled piece 4 among the figure.
