Multi-line cutting machine vertical feed device
One, technical field:
The utility model relates to cutting machine, particularly the feed arrangement of cutting machine.
Two, background technology:
The multi-line cutting machine feed arrangement is generally slide unit is housed on the column at present, slide unit can move up and down under motor-driven and realize the feeding of workpiece, because slide unit and on the network cutting head lay particular stress on, for counterpoise, generally bascule is set at the slide unit other end, as iron block or oil cylinder etc., but these methods or too outmoded heaviness or dangerous.
Three, summary of the invention:
The purpose of this utility model is to overcome above-mentioned not enough problem, and a kind of multi-line cutting machine vertical feed device is provided, and compact conformation, precision height, operates steadily, and is safe and reliable.
The technical scheme that the utility model is adopted for achieving the above object is: multi-line cutting machine vertical feed device, relate to the column slide unit, slide unit is installed on the column, and servomotor deceleration device output connects slide unit, slide unit and on the bascule of network cutting head be speed control.
Described slide unit is connected with servomotor speed brake setting by feed screw nut's device.
Described slide unit rolls with guide rail and cooperates, and guide rail is for intersecting the roller line slideway.
Described slide unit and servomotor deceleration device junction and guide rail movable part are equipped with multilayer and move protective cover.
The inner source of the gas that connects of described feed arrangement slide unit, gas flow is the malleation air-flow, forms air seal.
Described column slide unit is an all steel welding column slide unit.
The utility model has outstanding feature compared with similar products: drive the ball-screw Mobile Slide by a servomotor through decelerator and carry out vertical feed, adopt speed control to replace general weight balance device or hydraulic balance device, not only can balance slide unit weight, and the control accuracy height, operate steadily, safe and reliable; Adopt intersection roller line slideway, compact conformation, good rigidly, it is low to rub; Column slide unit connecting portion and guide rail movable part adopt hermetically sealed multilayer to move protective cover, prevent that effectively mortar from entering among guide rail and the feed screw nut; Slide unit adopts all steel welding slide unit, rigidity intensity height, and easily processing economizes die model, saves cost.
Four, description of drawings:
Fig. 1 is the utility model structural representation.
Fig. 2 is the B-B cutaway view of Fig. 1.
Fig. 3 is an I enlarged drawing among Fig. 1.
Five, the specific embodiment:
Multi-line cutting machine vertical feed device as shown in Figure 1, 2, adopt all steel welding column slide unit, speed control 3 is as the slide unit bascule, slide unit guide rail 5 is for intersecting the roller line slideway, guide rail rolls with slide unit 4 and cooperates, slide unit is installed on the column 7, and servomotor deceleration device 1 output connects slide unit by feed screw nut's device 2; In order to prevent that effectively mortar from entering motive position, slide unit and servomotor deceleration device junction and guide rail movable part are equipped with multilayer and move protective cover 6 (as Fig. 3), the inner source of the gas that connects of feed arrangement, and gas flow is the malleation air-flow, forms good air seal.
During work, servomotor drives the ball-screw Mobile Slide through decelerator and carries out vertical feed, carries out the workpiece cutting, the slide unit reposition that makes progress after cutting is finished, in this motion process, speed control plays the effect of balance slide unit and network cutting head weight and safe operation; Simultaneously the multilayer proofing cover moves with slide unit, and forced draft remains certain pressure, prevents that mortar from entering motion parts, thus accurate ball screw and roller bearing parts of protection effectively.
