Description

A kind of double-diagonal member cutting machine

Technical field

A kind of a kind of the present invention relates to cutting machine, more particularly to double-diagonal member cutting machine.

Background technology

At present, cutting machine is widely used in the cutting processing of various different workpieces, achieves large development.Existing cutting Machine generally comprise base, the workbench being located on base and rotating mechanism, by support be connected on rotating mechanism for cutting The saw blade of workpiece, the belt wheel transmission device for driving saw blade rotation, the driving means of driving pulley actuating device, to a certain extent The cutting task of some section bars or workpiece, but the following problem of generally existing can be completed：

One is that saw blade positioning clamping device includes that clip plate and outer plate, saw blade are located between clip plate and outer plate and quilt Clamp, but the surface of clip plate and outer plate is burnishing surface, saw blade is only merely be clamped at clip plate and outer plate flat In plate face so that positioning clamping effect is poor, and clip plate is larger with outer plate occupied area so that be located in clip plate with The output shaft of outer plate is also longer, so that the protective cover width being located at outside saw blade is also larger, so as to cause consumptive material larger and cost Higher.

Two is that preventer generally adopts fixed blade guard or fixed protection plate, also has in fixed blade guard or fixed protection Install flexible blade guard or mobile protective panel on plate additional, but the problem that above-mentioned preventer is primarily present is：On the one hand it is fixed The protective range of protective cover or fixed protection plate is limited, and cutter sweep can not follow the movable and movable anti-of cutter sweep when cutting Shield；On the other hand it is that existing fixed blade guard upper band flexible blade guard or mobile protective panel have flexible blade guard or movable anti- Backplate is not concentric setting with fixed blade guard or fixed protection plate so that flexible blade guard or mobile protective panel consumptive material are more And heavier-weight and relatively costly.

Three is that driving means adopt gear-box, gear case body generally to adopt metal cabinet, both heavy, ventilation and heat performance Poor, relatively costly, and generally using the motor of the external sliding tooth roller box work of gear-box so that as the electricity of driving means Machine and gear-box are present to be installed inconvenience, takes up room excessive and affect cutting machine integral installation and work；Four is belt wheel transmission Device adopts pulley gear, and belt generally using the belt of six cannelures, mainly ask by the belt of six cannelures Topic is：First, the friction during belt saw high speed operation of 2400W between belt and belt pulley is larger so that belt, belt pulley Easy to wear and service life is shorter, or even easily there is the excessive phenomenon for causing belt to burn of belt friction；Second, six annulars The belt width of groove is larger so that the elastic force of belt is less, tensile force is not sufficiently stable and it is relatively time consuming laborious to assemble；Third, six The belt consumptive material of cannelure is more so that relatively costly.

Additionally, also exist after slip cross bar is slid onto maximum position easily drop, after-frame and cranking arm and is unloaded to head at heaviness Power cushioning effect is poor, materials waste the shortcomings of seriously causing relatively costly in the package assembly of base and extension rod.

Content of the invention

The present invention is suffered from the drawback that for double-diagonal member cutting machine in prior art：One is saw blade positioning clamping device Including clip plate and outer plate, saw blade is located between clip plate and outer plate and is clamped, but the surface of clip plate and outer plate It is burnishing surface, saw blade is only merely to be clamped in the platen surface of clip plate and outer plate so that positioning clamping effect is poor, And clip plate is larger with outer plate occupied area so that the output shaft for being located in clip plate and outer plate is also longer, so that setting Protective cover width outside saw blade is also larger, so as to cause consumptive material larger and relatively costly；Two is that preventer is generally adopted admittedly Determine protective cover or fixed protection plate, also have and flexible blade guard or movable protective is installed additional on fixed blade guard or fixed protection plate Plate, but the problem that above-mentioned preventer is primarily present is：On the one hand it is the protective range of fixed blade guard or fixed protection plate Limited, cutter sweep cut when can not follow cutter sweep activity and movable protective；On the other hand it is existing fixed protection There is flexible blade guard or mobile protective panel with fixed blade guard or fixed protection in cover upper band flexible blade guard or mobile protective panel Plate is not concentric setting so that flexible blade guard or mobile protective panel consumptive material is more and heavier-weight and relatively costly；Three are Driving means adopt gear-box, and gear case body generally adopts metal cabinet, both heavy, ventilation and heat performance has been poor, cost compared with Height, and generally using the motor of the external sliding tooth roller box work of gear-box so that as the motor and gear-box of driving means Exist and inconvenience is installed, is taken up room excessive and is affected cutting machine integral installation and work；Four is that belt wheel transmission device adopts skin Belt wheel transmission device, generally using the belt of six cannelures, the subject matter of the belt of six cannelures is belt：Its During the belt saw high speed operation of, 2400W, friction between belt and belt pulley is larger so that belt, belt pulley easy to wear and Service life is shorter, or even the excessive phenomenon for causing belt to burn of belt friction easily occurs；Second, the belt of six cannelures Width is larger so that the elastic force of belt is less, tensile force is not sufficiently stable and it is relatively time consuming laborious to assemble；Third, six cannelures Belt consumptive material is more so that relatively costly；Additionally, also exist after slip cross bar is slid onto maximum position and easily dropping, after-frame and cranking arm Heavy and the buffering of head is acted on materials in the package assembly of poor, base and extension rod waste seriously cause cost compared with High the shortcomings of, there is provided a kind of clip plate is coaxial with flexible blade guard for inlaid type positioning clamping, fixed blade guard with outer plate The heart is arranged, front casing and rear box are covered and rear box and motor housing are connected as a single entity to form gear-box and gear-box and motor outside Shell is that plastics are made, consumptive material is less, lighter in weight, lower-cost double-diagonal member cutting machine.
