锯床系统伺服地位节制模块接纳采样插补和预感节制相连系的地位节制(详细节制略),决议封闭送料油缸的地位,使送料油缸遏制时恰好到达方针地位。因为电磁机器滞后及活动惯性,经由过程“通”“断”节制送料滑台挪动0.1mm几近不能够的。为了保障最小送料长度及送料精度,后钳使送料滑台撤退退却到到LK地位,而后向前挪动到展望地位LT封闭送料电磁阀。当送料油缸活动遏制时后钳夹紧。

 

圆锯床

圆锯床也称圆锯机,分全主动与半主动。圆锯片作改变的切削活动,同时随锯刀箱作进给活动。圆锯床按锯片进给标的目的又分为卧式(程度进给)、立式(垂直进给)和摆式(绕一支点摆动进给)3种。另外另有各类公用圆锯床,如用于切割大型铸件浇冒口的点头锯床;用于钢轨锯切和钻孔的锯钻结合机床。

 

带锯床

环形锯带张紧在两个锯轮上,并由锯轮驱动锯带停止切割。带锯床首要有立式和卧式两种。立式带锯床的锯架垂直设置,切割时工件挪动,用以切割板料和成形整机的曲线表面,还可把锯带换成锉链或砂带,停止修锉或打磨。卧式带锯床的锯架程度或倾斜安排,沿垂直标的目的或绕一支点摆动的标的目的进给,锯带普通改变40°,以坚持锯齿与工件垂直。卧式又分为铰剪式、双立柱、单立柱式带锯床;按照利用环境分为手动型(经济型手动送料手动切割物料)、主动型;按照利用节制器的主动化法式可分为手动型(半主动手动送料)全主动型(主动送料主动切割)

 

弓锯床

装有锯条的锯弓作来去活动,以锯架绕一支点摆动的体例进给,机床布局简略,体积小,但效力较低。弓锯床锯条的活动轨迹有直线和弧线两种。弧线活动时锯弓绕一支点摆动一小角度,每一个锯齿的切入量较大,排屑轻易,效力较高,旧式弓锯床大多接纳这类体例。

 

 

The servo position control module of sawing machine system adopts the position control combining sampling interpolation and preview control (the specific control is omitted), which determines the position of closing the feeding cylinder, so that the feeding cylinder just reaches the target position when it stops. Due to the hysteresis and inertia of electromagnetic machinery, it is almost impossible to control the movement of the feed slide by 0.1 mm through "on" and "off". In order to ensure the minimum feeding length and feeding accuracy, the rear tongs make the feeding slide back to LK position, then move forward to the predicted position LT, and close the feeding solenoid valve. When the feeding cylinder movement stops, the rear clamp is clamped.

Circular sawing machine

Circular saw machine, also known as circular saw machine, is divided into automatic and semi-automatic. The circular saw blade makes a rotary cutting motion, and at the same time, it makes feed motion with the saw blade box. According to the feed direction of saw blade, circular sawing machine can be divided into horizontal (horizontal feed), vertical (vertical feed) and pendulum (swing feed around a fulcrum). In addition, there are various kinds of special circular sawing machines, such as the moving head saw for cutting large casting risers, and the combined sawing and drilling machine for rail sawing and drilling.

Band sawing machine

The circular saw belt is tensioned on two saw wheels, and the saw wheel drives the saw belt to cut. There are two main types of band sawing machines: vertical and horizontal. The saw frame of vertical band sawing machine is set vertically, and the workpiece moves during cutting, which is used to cut the curve contour of sheet metal and forming parts. The saw band can also be replaced by file chain or abrasive belt for filing or grinding. The saw frame of horizontal band sawing machine is arranged horizontally or obliquely, feeding along the vertical direction or swinging direction around a fulcrum. The saw band is generally twisted by 40 ° to keep the saw tooth perpendicular to the workpiece. The horizontal type is divided into scissor type, double column type and single column type band sawing machine; according to the use situation, it can be divided into manual type (economical manual feeding, manual cutting material) and automatic type; according to the automatic program of the controller, it can be divided into manual type (semi-automatic manual feeding) and full-automatic (automatic feeding and automatic cutting)

Sawing machine

The saw bow equipped with saw blade makes reciprocating motion and feeds by swinging the saw frame around a fulcrum. The machine tool has the advantages of simple structure, small volume and low efficiency. There are two kinds of moving tracks of the saw blade of the sawing machine: straight line and arc. When the arc moves, the saw bow swings around a fulcrum with a small angle. The cutting amount of each saw tooth is large, the chip removal is easy, and the efficiency is high. This method is mostly used in the new type of sawing machine.
