Abstract

A feeding and cutting mechanism of machinery is mainly composed of a limiting cam 1, a worm gear 2, a worm 3 and a limiting hinge pin 9. The worm gear 2 is arranged on a feeding and cutting rotation shaft 5 on the right side of an arm plate 4 of a dividing and cutting machine, the worm 3 is arranged under the worm gear 2, the limiting hinge pin 9 is arranged on the worm gear 2, the limiting cam 1 is arranged on the feeding and cutting rotation shaft 5 on the right side of the worm gear 2, a support seat of the worm 3 is fixed on the arm plate 4, and a hand wheel is arranged at the left end of the worm gear 3. The feeding and cutting mechanism is short in adjusting time, high in speed, safe and reliable, and capable of reducing labor intensity and improving working efficiency.

Description

Machinery advances by cutter mechanism

Technical field

The utility model is mainly used in thin coiled material cutting machine, and a kind of machinery advances by cutter mechanism.

Background technology

Thin coiled material cutting machine is when cutting operation, and along with the conversion of coiled material specification, frequent adjustment cutter adjust the back lash of thereupon adjusting upper and lower cutter behind the cutter and both advanced by cutter to adjust, to reach the effect of cutting of the best.It is traditional that to advance by cutter be at an end spindle nose that advances by the cutter gyroaxis one square body or hexagon body to be set; Side or allen wrench carry out the manual work adjustment in adopting, and not only time-consuming but also require great effort, labor strength is big; Non-cutting time is long; And, be difficult for guaranteeing original adjustment effect along with the vibrations of cutting machine, therefore affect to cutting quality.For a long time, people are seeking the effective way of dealing with problems always.

The purpose of the utility model is to advance the weak point by cutter in order to overcome tradition, therefore designed the adjustment time short, speed is fast, safe and reliable, a kind of machinery that reduces labor intensity advances by cutter mechanism.

Summary of the invention

Machinery advances by cutter mechanism; Mainly constitute by limit cam 1, worm gear 2, worm screw 3 and 9 of spacing bearing pins; Cutting right-hand the advancing to lean on the cutter gyroaxis 5 and be provided with worm gear 2 of horn plate 4; Worm screw 3 is equipped with in the below of worm gear 2, and worm gear 2 is provided with spacing bearing pin 9, in worm gear 2 right-hand advancing by on the cutter gyroaxis 5 limit cam 1 is housed.The supporting seat of worm screw 3 is fixed on the arm plate 4, and its left part is provided with handwheel.

The beneficial effect of the utility model is: the adjustment time is short, speed is fast, safe and reliable, reduces labor intensity, and increases work efficiency.

The specific embodiment

Machinery advances by cutter mechanism, and enforcement is also uncomplicated, it should be noted that; Worm gear 2 is slightly variant with conventional worm gear; Because the worm gear of the utility model 2 is promptly will drive into to rotate by cutter gyroaxis 5 also to make gyroaxis 5 produce axial displacement, therefore, the worm-gear toothing of worm gear 2 need be processed into linear pattern to satisfy the needs that drive gyroaxis 5 axial displacements; Worm screw 3 be provided with two bearing blocks and with bolt to the sidewall of cutting horn plate 4; The other end of worm screw 3 is equipped with handwheel, and in fact limit cam 1 is exactly the block that a circle wheel is provided with a convexity, and spacing bearing pin 9 is to be fixed to accordingly on the worm gear 2.During work, left-handed handwheel, worm screw 3 drives worm gear 2 and rotates; Make cutter shaft 8 swings 120 degree by worm gear 2 through advancing by cutter gyroaxis 5 and two rotary supports 7, cutter 6 separates with following cutter, and can change or adjust cutter 6 this moment; Adjust the position of location adjustment screw 10 simultaneously; Dextrorotation handwheel again after adjusting, rotary support 7 contacts continuation dextrorotation handwheel just with location adjustment screw 10 when block contacts on spacing bearing pin 9 and the limit cam 1; Drive into by the internal thread on the worm gear 2 and to produce axial displacements by cutter gyroaxis 5 and accomplish into, make upper slitter and following cutter reach the optimal engagement state and cut quality with assurance by the cutter action.The utility model advances by cutter gyroaxis 5 maximum axial displacement amounts when advancing by cutter be 3 millimeters.

Claims (2)
