Abstract

The utility model discloses a capsule dynamic state inflated cutting device used for the peripheral direction cutting to a fabricated rubber product, belonging to the technical field of rubber plastic processing. The utility model is characterized in that a selective headstock is connected with a belt actuator, a compound capsule device is arranged between the selective headstock and a poppet stock, the upper end of the compound capsule device is provided with a cutting knife frame, and the compound capsule device and the cutting knife frame are installed on a bed together. The expansion quantity of diameter after inflated is used by the utility model to alternate all specification core rods of expansion range, technical equipment is simplified, production cost is reduced, and production quality is enhanced. Labor strength is reduced and repair management is simplified for the weights of core rods are reduced.

Description

Dynamic aerated cutter for capsule

A kind of capsule dynamic inflation cutter sweep is used for the circumferential cutting to product of rubber and plastic, belongs to the rubber and plastic processing technique field.

Before the utility model is made,, all adopt segment bounds rigidity cutting plug to process cutting to the circumferential cutting of tubular products of rubber and plastic such as cushion rubber, flute profile band, light and thin type dermatotome.This plug is made up of steel iron core, aluminium matter skin, attachment pegs, expansion thimble.Because above product specification is more, the plug of essential more all size, plug is many, and floor space is big, and the manufacturing cost height; Use processing inconvenient, the labour intensity height is unfavorable for maintenance.

The purpose of this utility model is to overcome above-mentioned weak point, thereby provides a kind of simple in structure, easy to use, can utilize expanded in diameter amount after the inflation to substitute the capsule dynamic inflation cutter sweep of all interior specification rigidity plugs of expansion scope.

The main solution of the utility model capsule dynamic inflation cutter sweep is achieved in that it mainly by adjustable sealing headstock, belt drive unit, cutting knife, the complex type capsules device of pressing, and lathe bed, tailstock are formed.Headstock connects belt drive unit, and the complex capsule device is housed between headstock and tailstock, and cutting knife is equipped with in complex capsule device upper end.Above-mentioned parts are installed on the lathe bed.

Description of drawings:

Fig. 4 is the utility model capsule dynamic inflation cutter sweep cutting knife structure chart;

Fig. 5 is the utility model capsule dynamic inflation cutter sweep complex capsule structure chart;

Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:

The utility model mainly is made up of the adjustable sealing rotation headstock 1, belt drive unit 2, cutting knife 3, complex capsule device 4, lathe bed 6, tailstock 7, motor 11 of pressing.Above-mentioned parts are installed on the lathe bed 6.The movable sealing headstock is by bearing 15,19,

dynamic sealing device

14,20, and bearing 16,23, inflation main shaft 18, valve inside 24, centring sleeve 25, position-arresting disk 26, spring 21 is formed.The rotating ring of

dynamic sealing device

14,20 is separately fixed at the two ends of inflation main shaft 18, stationary ring is separately fixed on the

bearing

15,19, the inflation main shaft is fixed on the casing 17 by bearing 16,23, valve inside 24 is installed on the centring sleeve 25 with sliding matching mode, centring sleeve 25 is fixed on the inflation axle 18 with threaded connection mode again, and position-arresting disk 26 is fixed on the centring sleeve 25.Cutting knife is by tool axis 8, knife rest 9, balanced pinch roller 12 are installed on the bearing of two-dimentional deviation correcting device 27, and be assemblied on the knife rest 9, knife rest is connected on the tool support 28 by having the tool axis 8 of eliminating end play, under counterweight 5 and secondary spring effect, can move up and down neatly, realize cutting.Whole cutting knife assembly is fixed on the lathe bed 6 by tool support 28.The complex capsule device is by stop collar 29, and inflation cover 30, hollow skeleton 31, airflow layer 34, damaged layer 33, centration axis 35 are formed.Inflation core 30, centration axis 35 and hollow skeleton 31 closely cooperate and be pressed into the back weldering is one, and airflow layer 34 is enclosed within on the hollow skeleton 31, and two ends compress sealing with nut and packing ring and close, damaged layer 33 is enclosed within on the airflow layer 34, interchangeable, stop collar 21 are enclosed within on the inflation core 30, and be spacing fixing with screw.Complex capsule device 4 is clamped in headstock 1 and tailstock 7 centres as mold when cut workpiece, transmits moments of torsion by position-arresting disk 26 and stop collar 29.Compressed air through pressure regulation makes the expansion of capsule utricule through inflation pore 22, inflation axle 18, valve inside 24, inflation core 30, air-filled pore 32, and when cutting knife fell, main shaft rotated the dynamic cutting that realizes under the inflation pressurize automatically.Depth of cut can be regulated arbitrarily, and width is set up by blade row back-up ring 10.

Compared with the prior art the utility model has the following advantages:

1, adopts the capsule of dimension, utilize the expanded in diameter amount after inflating to substitute all size mandrils of expansion scope, and not limited by width series, simplified technological equipment, reduced the cost of production.

2, the rubber surface coefficient of friction so material to be cut can be close to the utricule surface after capsule, is difficult for axial float greater than the metal surface coefficient of friction, is difficult for causing heavy cutter phenomenon, has improved product quality;

Thereby 3, reduced plug weight and reduced labour intensity, simplified maintenance management thereby reduced plug quantity.

Claims

1, a kind of capsule dynamic inflation cutter sweep is by headstock, and belt drive unit, lathe bed, tailstock, motor are formed, and it is characterized in that being equipped with between headstock and tailstock the complex capsule device, and cutting knife is equipped with in complex capsule device upper end.
