Abstract

A spiral blade molding machine comprises a blade roller, two identical upper and lower adjacent truncated cone roller pairs arranged on a frame at staggered positions, wherein the rolling center line between two rollers of the upper roller pair has a planar included angle alpha with the rolling center line between two rollers of the lower roller pair; and a groove-shaped guide wheel is arranged on the frame below the two roller pairs for supporting the outer back section of a spiral blade to be processed. The upper and the lower roller pairs of the spiral blade molding machine are respectively driven by a transmission mechanism and has the advantages of strong power, no occurrence of material jamming and stable and reliable operation. Additionally, a molding support guide wheel is provided to further ensure the accuracy and the stability of the diameter and pitch of the spiral blade. The machine has simple, compact and reliable structure.

Description

A kind of screw blade make-up machine

Technical field

The utility model relates to a kind of make-up machine of leather cutting screw blade, belongs to the roll forming process equipment of metallic plate, bar.

Background technology

Chinese patent CN2073780U discloses a kind of " screw blade make-up machine ", this machine mainly is made up of the symmetry guiding distortion roller of a pair roller and both sides thereof, steel disc bar one end that coils circle is in advance sent into the guiding distortion roller of this machine one side, enter opposite side guiding distortion roller through the roll traction, promptly roll out the helical blade of a constant pitch.Succeeding in developing of this machine changed the backward production that screw blade for a long time relies on manual machine-shaping, improved production efficiency and the product quality of screw blade greatly.But through long-term practice, find that this machine still has the improved shortcoming of need, the one, blade is only drawn by a pair roller in the operation of rolling, through two groups of distortion roller distortions, and two groups of distortion rollers are only made passive rotation, if in the chance dish disk when being stained with the carburizing residue, the roller that tends to deform gets stuck in the work, and this reflects rolling being short of power; The screw blade pitch precision of this machine production is not good enough in addition.

Summary of the invention

The purpose of this utility model provides a kind of compact conformation, running is reliable and stable, screw blade pitch machining accuracy is high novel screw blade make-up machine.

Technical solution of the present utility model is: it has the blade roll, and on frame, be furnished with neighbouring and the identical truncated cone body roll of two pairs of structures dislocation is right, be that rolling between the two right rolls of topping roll cut center line and bottom roll and rolling between two rolls cut had plane included angle α between the center line, the groove shape directive wheel at the outer back of support spiral processing blade is installed on the frame of two breaker rolls below.

Described two bottom rolls and power transmission shaft thereof are to be installed on down on the boxboard by its block, two topping rolls and power transmission shaft thereof are installed on the boxboard by its block, and reach the corresponding arc-shaped slot and the set bolt that can make the boxboard activity orientation that offer on the following boxboard on the last boxboard.

The beneficial effects of the utility model are: top and bottom rolls is to directly being driven by transmission mechanism respectively, and power is strong, the phenomenon that can not get stuck, and it is reliable and stable to turn round; Set up blade moulding support directive wheel in addition, further guaranteed the accuracy and the stability of circular knife diameter and pitch; This machine overall structure is simple, compact, reliable.

Description of drawings

Fig. 1 is the utility model general structure schematic diagram.

Fig. 2 is that top and bottom rolls of the present utility model is to the relative position schematic layout diagram.

The specific embodiment

The utility model is described in further detail with embodiment below in conjunction with accompanying drawing.

Be fixed with boxboard 15 under the level on the frame 17, following boxboard 15 bottom surfaces are equipped with a pair of block 5, the front and back end of block 5 is equipped with the bearing 10 of power transmission shaft 11, be provided with truncated cone body roll 1 respectively at the two power transmission shaft leading sections that stretch out two blocks, 5 front end faces, 2, roll 1, remain with the uniform gap that is slightly larger than the processing blade thickness between 2, the power transmission shaft 11 that wherein is provided with roll 2 is connected by the output shaft of shaft coupling 8 with reduction gearing mechanism 9 end thereafter, frustoconical driving gear 7 is installed on this power transmission shaft, the driven frustoconical gear 6 that is meshed with driving gear 7 is installed and be provided with on the power transmission shaft of roll 1; Under level, be mounted with boxboard 12 on the level on the boxboard 15, a pair of block 5 and power transmission shaft 11 are installed on the last boxboard 12 equally, bearing 10, be provided with frustoconical roll 3 respectively at the two power transmission shaft leading sections that stretch out two blocks, 5 front end faces, 4, roll 3, remain with the uniform gap that is slightly larger than the processing blade thickness between 4, the power transmission shaft 11 that wherein is provided with roll 4 is connected by the output shaft of shaft coupling 8 with reduction gearing mechanism 9 end thereafter, frustoconical driving gear 7 is installed on this power transmission shaft, the driven frustoconical gear 6 that is meshed with driving gear 7 is installed and be provided with on the power transmission shaft of roll 3; Offer arc-shaped slot 13 on the last boxboard 12, also offer corresponding with it arc-shaped slot on the following boxboard 15, locate the position of boxboard 12 movably by set bolt 14, thereby can regulate rolling between the topping roll 3,4 by boxboard in the displacement 12 and cut the size of rolling the plane included angle α that cuts between the center line B between center line A and the bottom roll 1,2, also be the processing pitch of adjustable screw blade; Above-mentioned top and bottom rolls centering wherein is separately installed with baffle plate 26 on the rear end face of the front end face of a roll and another roll, to prevent that blade skids off in the process; The groove shape directive wheel 24 at support spiral processing blade 27 outer backs is installed on the frame of two breaker rolls below, this directive wheel 24 is installed on the lift adjustment seat 19 by elevating lever 23, lift adjustment seat 19 is installed on again on the slide block that is provided with adjusting screw(rod) 16 22 that is arranged in vertical sliding chute seat 20, and vertically sliding chute seat 20 then is installed on the slide rail cover 21 of the cross slide way 25 that is driven by screw rod 18.
