Description

Machine for milling, cutting and sawing

Technical field

The utility model belongs to the steel tubular goods cutting equipment, is specially adapted to circle, square has, seamless tubular goods crop, back-end crop, cuts sizing length, a kind of Machine for milling, cutting and sawing that sampling is cut off.

Background technology

At present, the steel tube factory is to having, crop, the back-end crop of seamless circle, square bar tubing, cutting sizing length, sampling need be cut off tubing, mostly adopt the sawing mode, saw blade cutting machine commonly used, it is by the saw blade of base, motor, motor-driven high speed steel, and with the feeding of hand or hydraulic drive, simple upper and lower clamping device, circle that needs are cut off or square bar tubing are put into the clamping device clamping on the base.Progressively push motor-driven saw blade to steel pipe then, it is disconnected that steel tubular goods is imposed uniformity without examining individual cases.It has following defective and weak point:

1, the saw blade used of sawing is the circular saw blade of high speed steel, because the change of steel pipe material, not only blade wear severity needs often in time to change, and loses time, reduces work efficiency; Restricted by cutting machine structure,, or adopt the screw rod clamping of rotating or a upper and lower clamping of going up hydraulic cylinder is only arranged with hand in the tubing cut end, reliable clamping often, especially to the cut-out of short tube material,, be easy to yaw and wag the tail because clamping is not firm, cause the saw kerf section deflection that cuts out, precision is not high, influences the saw kerf cross section quality, when particularly promoting to be fed near steel pipe with hydraulic cylinder, it is excessive and damage saw blade often to produce greater impact or bite, has a strong impact on the raising of work efficiency.

2, during sawing, noise is big.

Summary of the invention

The utility model purpose is defective and the weak point that exists in above-mentioned technology, and provide the milling mode that both adopts with alloy steel milling head, make stable cutting, wear-resisting, noiselessness, adopt again the forward and backward clamping of long and short tubing and solid and reliable a kind of Machine for milling, cutting and sawing.

The purpose of this utility model realizes with following technical scheme: Machine for milling, cutting and sawing comprises base, motor-driven circular saw blade, hydraulic feed, clamping device, the magnetic chip area, be characterised in that: its structure is mainly by the saw of the frame shape on base body, a left side, right slide, level, vertical guide rail, a left side, right sawing head, X, the feed arrangement of Y plane coordinates direction, on hydraulically powered, down, a left side, right chuck is formed, the saw body of dress frame shape on base, with indulging of saw body framework, horizontal central axis intersection point is as the center of clamping steel pipe workpiece, corresponding with steel pipe otch cross section place, adorn on the framework hydraulically powered on, down, a left side, the clamping device that right chuck constitutes, left side at clamping device, the right side, the symmetry dress is left on one's body in saw, right slide, symmetry is loaded onto on the frontal plane of two slides, the sawing head of following dislocation, with a relative left side, a sawing side, pretending parallel mutually on the right slide face respectively is two groups of vertical guide rails of one group with two guide rails, corresponding with two groups of vertical guide rails, have the chute that can hold two groups of guide rails in the sawing head side relative with slide, guide rail in two groups of chutes is inserted in the chute respectively, formation can go up, mobile down Y plane coordinates direction feed arrangement, on clamping device, pretending mutually parallel on the cruciform bracing at following two ends is two groups of horizontal guide rails of one group with two guide rails, corresponding with two groups of horizontal guide rail positions, in the slide plane relative, have the chute that can hold horizontal guide rail with saw body framework, horizontal guide rail places in the chute, and formation can be left, the right X plane coordinates direction feed arrangement that laterally moves.Described frame shape saw body is to adopt I-steel, channel-section steel to make; A described left side, right sawing head is respectively by motor-driven transmission case, the milling head saw blade that is connected with transmission case is formed, be divided into a left side, right sawing head, symmetry is loaded on the left side of tubing otch section, right both sides, or to make up down with the right side on the left side or to make up down and on the right side with the left side, just when the milling head saw blade in left side when the left-half of tubing otch section is carried out milling from top to bottom or from bottom to top, then the section of the milling head on right side circle is carried out milling from bottom to top or from top to bottom from the right half part of tubing otch section, then through a left side, the two halves that right milling becomes forms the whole otch section of tubing; Described milling head saw blade is to adopt the milling head welding-on of alloy steel to constitute the same saw blade of milling cutter; The feed arrangement of described Y plane coordinates direction, form by servomotor, ball-screw, one end of ball-screw connects servomotor, the other end and the transmission case of ball-screw join, open servomotor, just drive ball-screw and make milling head saw blade on the transmission case along direction feed of Y plane coordinates or withdrawing; The feed arrangement symmetry of described X plane coordinates direction is contained in the top of left and right slide and forms left and right feed arrangement, form by servomotor, ball-screw respectively, ball-screw one end joins with the both sides of hydraulic cylinder respectively, the other end of ball-screw connects servomotor respectively, open the servomotor of left and right feeding, just drive milling head saw blade on the left and right slide along the feed or the withdrawing of X plane coordinates direction by ball-screw.Why adopt servomotor,, avoid making milling steadily reliable because of machinery drives the impact of coming because its control feed distance is accurate, and noiselessness; The clamping device of described hydraulically powered upper and lower, left and right chuck, be loaded on the front and back ends of processed tubing respectively, it is made up of hydraulic cylinder, control valve, chuck, on the liquid oil cylinder control valve is housed, and opening controlling valve, just can make the processed tubing of chuck clamping; When the circular pipe of milling minor diameter, the clamping device that can only form with the upper and lower chuck of Driven by Hydraulic Cylinder.Combine the above technical measures of being taked and realize the purpose of this utility model.

Compared with prior art: the utlity model has following advantage:
