Abstract
The utility model relates to the reducing tube diagonal rolling equipment, composed of a roller part and a roller feeding part, wherein, at least three sets of uniformly distributed rollers are provided; the roller feeding part comprises a roller frame, a guide block, a guide holder, a box body and a guide block propelling system; inthe rolling process, the rollers moves radially under the action of the force of the feeding system to realize the purpose of rolling reducing tubes; by adopting the utility model, a steel rolling enterprise can produce conical tubes and ladder tubes with different specifications, the cost is low, and the quality is good.
Description
The utility model relates to the rolling equipment of a kind of conical pipe, laddertron.
It is several that the reducer pipe manufacturing process of present stage mainly contains the system of dialling, extruding and pressure processing.Which kind of method no matter, its production efficiency is all very low, and operation is various, and it is just bigger that the reducer pipe of big specification is processed difficulty.What occurred in recent years has produced all bigger conical pipe of diameter, length with sheet material through the pressure processing method of multiple working procedure and has satisfied that electric industry department transmission of electricity bar uses and the needs of every profession and trade capital construction, but this method uses equipment huge, operation is many, investment of production equipment is very big, causes the difficulty of promoting the use of.
The purpose of this utility model is to provide a kind of brand-new reducer pipe production equipment, makes it reach reduced investment, work efficiency height, can replace the oblique milling reducer pipe equipment of traditional diamond-making technique.
The utility model is to realize like this;
Its basic principle of oblique milling reducer pipe equipment is to utilize existing section bar oblique milling technology, and its roll can be moved radially, and obtains the purpose of rolling conical pipe or laddertron by the method that applies constant or interim change pressure to roll.
Its concrete structure is; This oblique milling reducer pipe equipment is made up of roll part and roll feeding two parts, roll partly comprises roll, roll mandrel and roll dynamical system, roll is contained on the roll mandrel, roll axis and rolling centerline are angled, it is characterized in that the roll part will have uniform three groups at least, the roll feeding partly comprises roll stand frame, guide pad, guide holder, casing, and guide pad propulsion system, roll mandrel is contained on the roll stand frame, roll stand frame is fixed on the guide pad, guide pad is contained in the guide holder, can slide each guide pad propulsion system thereon, guide holder is contained on the casing.
The guide pad propulsion system is made up of worm screw, worm gear, guiding screw mandrel, worm gear case, feather key, gear, bull gear and the power set that act on worm screw, worm gear is contained in the worm gear case, and in worm engaging, the worm gear endoporus is a threaded engagement with the guiding screw mandrel, guiding screw mandrel lower end is connected with guide pad, has keyway on the screw mandrel that leads and is feather key with casing via hole keyway and is connected.Worm screw shaft extension one end is equipped with gear, and each gear of organizing the guide pad propulsion system is engaged in the bull gear that is contained on the casing jointly, and the other end can be adorned power set.When rolling reducer pipe, start the worm screw power set, worm gear is rotated, the guiding screw mandrel that drives on the worm gear moves up and down under the feather key effect, thereby driven guide pad, moving of roll stand frame, roll is because gear on each roll stacks worm screw and bull gear engagement have realized each roll synchro-feed.
The guide pad moving system can be above-mentioned mechanical drive mode, also can be the hydraulic servo system, or alternate manner.Purpose is to obtain one to act on constant or be interrupted change power on the guide pad, realizes the purpose of rolling conical pipe or laddertron.
Adopt the utility model just can produce various reducer pipe and satisfy needs of society, greatly reduce the cost of producing reducer pipe with other processing method, and quality is higher from steel rolling enterprise.
The utility model is described in further detail below in conjunction with accompanying drawing:
Accompanying drawing 1 is an oblique milling reducer pipe equipment front view;
Accompanying drawing 2 is oblique milling reducer pipe side views;
Accompanying drawing 3 is oblique milling reducer pipe schematic diagrams;
As shown in the figure, oblique milling reducer pipe equipment is made up of roll part and roll feeding two parts, roll partly comprises roll 4, roll mandrel 13 and roll dynamical system, roll is contained on the roll mandrel, roll axis and rolling centerline are angled, its roll part will have three groups of uniform rolls at least, the roll feeding partly comprises roll stand frame 12, guide pad 11, guide holder 7, casing 2 and guide pad propulsion system, roll mandrel 13 is contained on the roll stand frame 12, roll stand frame 12 is fixed on the guide pad 11, guide pad 11 is contained in the guide holder 7, can slide thereon, each guide pad propulsion system, guide holder is contained on the casing 2, the guide pad propulsion system is by worm screw 3, worm gear 8, guiding screw mandrel 1, worm gear case 10, feather key 9, gear 5, bull gear 6 and the power set that act on the worm screw 3 are formed, worm gear 8 is contained in the worm gear case 10 and in worm screw 3 and meshes, the worm gear endoporus is a threaded engagement with guiding screw mandrel 1, guiding screw mandrel lower end is connected with guide pad 11, have keyway on the guiding screw mandrel, be connected with feather key 9 with casing via hole keyway, worm screw shaft extension one end is equipped with gear 5, each gear 5 of organizing the guide pad propulsion system is engaged in the bull gear 6 that is contained on the casing 2 jointly, other end dress power set.When rolling reducer pipe, start the worm screw power set, worm gear is rotated, the guiding screw mandrel that drives on the worm gear moves up and down under the feather key effect, thereby driven moving of guide pad, roll, because gear 5 on each roll stacks worm screw and bull gear 6 engagements, realized the synchro-feed of each roll.
