时候:2019-09-02 23:00 点击次数:

锯床首要部件有底坐;床身、立柱;锯梁和传念头构;导向装配;工件夹紧;张紧装配;送料架;液压传动系统;电气节制系统;光滑及冷却系统;

 

底座

锯床底座为钢板焊接而成的箱形布局,床身、立柱牢固其上,底座内腔有较大空间,前左边为电气按钮节制箱,右边为电气配电板箱,中心由钢板焊成的液压油箱,腔内装有液压泵站,液压管路,右边为冷却切削液箱及水泵。

 

床身

床身为铸铁件,牢固在底座上,立柱由一巨细圆柱组成,大圆立柱作为锯架动的导轨,是用以支持锯梁高低起落活动,并保障切确的导向,小圆柱起帮助感化,从而保障锯条的一般切削。中心为夹料虎钳和手动送料机构,虎钳后方毗连有承接制品件的任务台,左边的夹紧装配为夹紧丝杆穿过液压夹紧油缸杆内孔,动弹手轮或按动按钮,使左闭口摆布活动。2:锯床合用场所:首要利用于机器,铸造,加工等的下料。

 

功效和特色

液压节制锯切速率,无极可调。油缸节制,进给安稳。按照客户须要可增添成整装配。按照须要有半主动和数控全主动可供挑选。可供转角度斜切锯床。

 

锯床产物范例

有搭钮式,单柱式,双柱式。龙门式及立式,分为半主动,数控全主动。

 

锯梁和传念头构

由厚钢板切割成形焊接而成,具备较强的刚性,其右后侧牢固有蜗轮箱,箱内的蜗轮与锯梁下面的主动轮固接,两者同步扭转,左边为主动轮和锯条张紧地位。锯条的反转展转活动由主机电、皮带轮、蜗轮付经两级变速将驱动为通报到主动轮,再由主动轮、锯条驱动主动轮来完成的,锯条运转速率共三档。

 

锯条导向装配

装配在锯梁支板的导向装配由左、右导向臂与导向头组成,左、右导向臂都可沿燕尾榫挪动(或右导向臂牢固在立柱套上),调剂两导向臂间间隔比工件尺寸宽40mm摆布。导向装配用于转变锯条的装配角,使锯条与任务台垂直,为保障锯条的切削精度,削减振动,在摆布导向臂各装有一组导向轮(转动轴承)和耐磨的导向块,锯条背部也有耐磨合金的导向块。

 

夹紧机构

右虎钳牢固在床身上,夹紧丝杆穿过液压夹紧油缸内孔,由丝杆毗连左虎钳沿导轨摆布挪动,当左虎钳间隔工件10-30MM时毗连。手按节制面板的钳紧或钳松按钳,使工件夹紧或松开。

 

张紧装配

张紧装配是由滑板座、滑板、丝杆等组成,当要将锯条张紧时,用扭力扳手按顺时针标的目的扭转可张紧锯条,处于任务状况。如锯床处于长时候停机状况,扭力扳手向逆时针标的目的扭转锯条松开。

 

 

The main components of the sawing machine include: bottom seat; bed, column; saw beam and transmission mechanism; guiding device; workpiece clamping; tensioning device; feeding frame; hydraulic transmission system; electrical control system; lubrication and cooling system; the main components of the sawing machine are as follows;

base

The base of the sawing machine is a box structure welded by steel plates. The bed and column are fixed on it. There is a large space in the inner cavity of the base. The front left side is the electric button control box, the right side is the electrical distribution board box, and the middle part is the hydraulic oil tank welded by steel plate. The hydraulic pump station and hydraulic pipeline are installed in the cavity, and the cooling and cutting fluid tank and water pump are on the right side.

Bed

The bed is made of cast iron and fixed on the base. The column is composed of large and small columns. As the guide rail of the saw frame, the large circular column is used to support the up and down movement of the saw beam and ensure accurate guidance. The small cylinder plays an auxiliary role to ensure the normal cutting of the saw blade. In the middle is the clamping vise and the manual feeding mechanism. In front of the vise is a worktable to receive the finished products. The clamping device on the left side is that the clamping screw rod passes through the inner hole of the hydraulic clamping cylinder rod and rotates the hand wheel or presses the button to make the left jaw move left and right. 2: Application: mainly used in cutting materials of machinery, forging, processing, etc.

Functions and features

Hydraulic control sawing speed, infinitely adjustable. Oil cylinder control, stable feed. Beam forming device can be added according to customer needs. According to the needs, there are semi-automatic and CNC full-automatic options. It can be used for angle cutting sawing machine.

Product type of sawing machine

There are hinge type, single column type and double column type. Gantry and vertical, divided into semi-automatic, CNC fully automatic.

Saw beam and transmission mechanism

The worm gear box is fixed on the right rear side of the box. The worm gear in the box is fixedly connected with the driving wheel above the saw beam. Both rotate synchronously. The left side is the tension position of the driven wheel and saw blade. The rotary motion of the saw blade is driven by the main motor, belt pulley and worm gear through two-stage speed change, which is then realized by the driving wheel and the saw blade driving the passive wheel. The saw blade operates at three speeds.

Saw blade guide

The guide device installed on the saw beam support plate consists of left and right guide arms and guide heads. Both the left and right guide arms can move along the dovetail tenon (or the right guide arm is fixed on the column sleeve), and the distance between the two guide arms is about 40mm wider than the workpiece size. The guide device is used to change the installation angle of the saw blade to make the saw blade perpendicular to the working table. In order to ensure the cutting accuracy of the saw blade and reduce vibration, a set of guide wheels (rolling bearings) and wear-resistant guide blocks are respectively installed on the left and right guide arms, and the guide blocks of wear-resistant alloy are also installed on the back of the saw blade.

Clamping mechanism

The right vise is fixed on the bed, and the clamping screw rod passes through the inner hole of the hydraulic clamping cylinder, and is connected by the screw rod. The left vice moves left and right along the guide rail, and is connected when the distance between the left vice and the workpiece is 10-30mm. Press the clamping or loosening clamp of control panel by hand to clamp or loosen the workpiece.

Tensioning device

The tensioning device is composed of slide plate base, slide plate, screw rod, etc. when the saw blade is to be tensioned, the saw blade can be tensioned by rotating clockwise with a torque wrench, and it is in working state. If the sawing machine is shut down for a long time, the torque wrench should be turned anticlockwise to loosen the saw blade.
