Abstract

A full-automatic precise cut-off machine for a cold-drawing roller carrier shaft consists of a rack, a bar cutting machine, an oil press, a feed mechanism and an electromagnetic clutch, wherein the bar cutting machine is fixed at the front end of the rack; the oil press is arranged above the bar cutting machine; the bar cutting machine is internally provided with a contactless switch; the feed mechanism is arranged behind the bar cutting machine on the rack and is used for conveying bars for the bar cutting machine; the electromagnetic clutch is arranged on the feed mechanism and is in electric contact with the contactless switch in the bar cutting machine; and a long-hole-shaped small gap die used for fixing the bars is fixedly arranged in the bar cutting machine. The full-automatic precise cut-off machine for the cold-drawing roller carrier shaft has a simple structure and high degree of automation, the problem that the end face of a discharge slot of the roller carrier shaft is deformed is solved, and the machining accuracy and the production efficiency of the roller carrier shaft are improved.

Description

The accurate cutting machine of full-automatic cold group of roller carrier shaft

Technical field

The utility model relates to a kind of cutting machine, particularly relates to a kind of cutting machine that is used for bar.

Background technology

Ribbon conveyer is the extensively short distance conveying equipments of utilization of national economy major industrys such as electric power, metallurgy, harbour, light industry.Carrying roller is the important spare part that supports the conveyer conveyor belt, and its quantity is many, requires quality high, needs long service life.

Though at present domestic majority carrying roller manufacturer all introduces and has adopted that advanced foreign technology such as steel pipe automatic cutting off table, steel pipe double end Che Kongji, carbon dioxide two-wheel automatic welding of circumferential seams are met sb. at the airport, pressing machine etc. automatically; But the cut-out of the roller carrier shaft that is used to form a complete production network is still comparatively backward; Key is after cutter cuts off; The otch distortion is big, does not meet product requirement.Therefore, most of manufacturers still adopt sawing machine and abrasive wheel cutting machine to cut off, and labour intensity is big, and cutting accuracy is low, and allowance is big, and contaminated environment can not form a complete production network.

Summary of the invention

The purpose of the utility model provides the accurate cutting machine of a kind of full-automatic cold group of carrying roller, to solve the problem of existing roller carrier shaft blanking cut ends facial disfigurement.

The accurate cutting machine of the full-automatic cold group of roller carrier shaft of the utility model is made up of frame, bar shears, hydraulic press, feed mechanism and electromagnetic clutch; Said bar shears is fixed on the frame front end; Hydraulic press is installed in the bar shears top; Noncontacting switch is installed in the bar shears, and feed mechanism places the rear of bar shears on the frame, is used for bar is flowed to bar shears; Electromagnetic clutch is installed on feed mechanism, electrically contacts with noncontacting switch in the bar shears.

Wherein, in bar shears, be installed with the little gap of the slotted hole type mould that is used for fixing bar.The big 0.35-0.5 millimeter of hole diameter ratio shaft material of this mould, slotted hole length is about the length of bar.When pressurization was cut off, the top and bottom of bar were by the whole arc surface contact of mould, and contact area is big, and unit pressure is little; Bar is flexible type not, and the otch end face is neat, and the axle head ovality is identical with the primitive axis material; Reduce the workload of axial end, practiced thrift steel, effectively guaranteed the crudy of product.

The accurate cutting machine of the full-automatic cold group of roller carrier shaft of the utility model has adopted high abrasion, long hole shape, the little gap mould that accurately resets; Realized ELEMENTARY INTRODUCTION TO NON; Overcome that waste material, contaminated environment are cut off in the cutting of sawing machine, abrasive machine, efficient is low, labour intensity is big, production cost is high; The defective that incompatible automatic matching in enormous quantities is produced, the roller carrier shaft two ends ovality of cut-out reaches the product technology requirement, adopts advanced control sensing; Drive technology has realized that roller material feeds automatically, locatees, cut-out, the material returned, numeration, the cyclic production process automation of feeding again.

The accurate cutting machine of the full-automatic cold roller carrier shaft of the utility model is simple in structure, and automaticity is high, has improved the machining accuracy and the production efficiency of roller carrier shaft.

Description of drawings

Fig. 1 is the structural representation of the accurate cutting machine of the full-automatic cold group of roller carrier shaft of the utility model.

Fig. 2 is the vertical view of Fig. 1.

Among the figure, 1. tailstock, 2. cradle, 3. reductor base, 4. frame, 5. worm speed reducer, 6. electromagnetic clutch, 7. motor, 8. bar shears, 9. hydraulic press, 10. feed mechanism.

The specific embodiment

The structure of the accurate cutting machine of full-automatic cold group of roller carrier shaft such as Fig. 1, Fig. 2 are made up of frame 4, bar shears 8, hydraulic press 9, feed mechanism 10 and electromagnetic clutch 6, and the little gap of slotted hole type mould is installed in bar shears 8.

Feed mechanism 10 places the rear end of bar shears 8 on the frame 4, is used for bar is carried the little gap of the slotted hole type mould that penetrates in the bar shears 8.Be connected with hydraulic press 9 in bar shears 8 upper ends, bar sheared through the motion of hydraulic press 9.Electromagnetic clutch 6 is positioned at a side of feed mechanism 10, is used to control self-feeding, and electromagnetic clutch 6 electrically contacts with the bar shears 8 interior noncontacting switches of installing.

Worm speed reducer 5 is fixed on the frame 4 through reductor base 3, and motor 7 transmissions by being installed in below the frame 4 drive feed mechanism 10 work.

Also be connected with the cradle 2 that supports with tailstock 1 in frame 4 back, be used to hold up bar and be transported to feed mechanism 10.

The course of work of the accurate cutting machine of full-automatic cold group of roller carrier shaft is: feed mechanism is delivered to bar in the little gap of the slotted hole type mould in the bar shears; After bar touches the stop noncontacting switch; Automatically close the feed mechanism electromagnetic clutch; Feed mechanism stops, and connects hydraulic press, bar shears work.Get into device for discharging behind the Cutting stick, feed mechanism restarts work, and bar is delivered in the bar shears, carries out next one circulation.

Claims
