CS268233B1 - Device for continuously made profile products' separating mechanism driving - Google Patents

Description

(57) The solution allows for increased performance and accuracy, reduced adjustment and adjustment of lengths or pitches for equipment continuously producing profiles when cutting or marking, punching, perforating, etc. Changing the length or pitch is accomplished by adjusting only one parameter of the mechanism. technological equipment used for continuous production. It can also be used in other fields, wherever we need to perform a certain technological operation while moving the product.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for driving a dividing mechanism of continuously manufactured profiled articles, or other technological equipment in continuous manufactured profiled materials, strips, tubes and the like.

The prior art solutions are very often constructed on the basis of a friction measuring of length by a fixed disk, one circumference length corresponding to one length or one pitch and by rotation a cutting saw is usually carried by a saw which performs translational or oscillating movement at the frequency of the technological operation. This method does not allow for a continuous change in the length of the manufactured profile products or a change in the spacing of marking, punching, perforation, knurling, etc. Other disadvantages of this solution are in low entrainment force or in low entrainment. lengths change on the device, often slippage occurs and therefore the inaccuracy of separation or pitch is dependent on friction conditions, the product transmits force and therefore it is often not only possible to attenuate it from a technological point of view, or cross-sectional deformations of profiles occur.

Another common solution is provided with a starting cue and the mechanism operates reversibly, periodically, with a certain delay, which is necessary to stabilize the mechanism and thereby achieve acceptable accuracy. The frequency of operation of such principles is below 1 / s, unless the device is equipped with a servo mechanism. Devices equipped with servo mechanisms can divide at frequencies up to 2 / s, but the tolerances и of perfect solutions are above 0.5 to 14 length or pitch, and often the ends or straightness of the thin-walled profiles is deformed. Another major disadvantage of such mechanisms is the generation of high velocities, accelerations and inertia forces that cause cross-sectional or longitudinal deformations.

The above mentioned drawbacks are eliminated by the device for carrying of dividing mechanisms of continuously produced profile products or also for carrying of other technological devices whose task is eg to periodically punch, mark, perforate, etc. in precise pitch, its essence by means of pins and a sliding body with a swinging straight lever, the driven end of which is also articulated by means of a pin to the technological device and is guided in a straight line parallel to the jack, parallel to the movement of the profile material. At least two articulated bearings of the rocking straight lever are provided in the bodies, in addition to the pivot pin, with a sliding linear guide oriented in the direction of the straight lever. The axis of swinging of the direct lever is adjustable perpendicular to the linear guide of the jack and to the guide of the technological equipment.

The higher and new effect of the present invention is to provide profile length tolerances of less than 0.1 4 lengths and a possible dividing frequency of the order of 10 divisions / sec, which increases by 50 4 the performance achieved by the mechanisms known in the world.

The advantages of the solution of the device according to the invention are illustrated in the attached figures, where Figure 1 is a front view of the device with partial section and Figure 2 is a plan view of the plane Λ-A of Figure 1.

Apparatus к drift separating mechanism of continuously produced profiled product is part of the machine for the production and separation, the shaft 2 J ^e is rigidly connected * to the drive cam 2, which is coupled with the jack 2 mounted in a straight guide 22 · on the jack 2 are fixed pulley - stones 10 and pin 22 »which is mounted ^on body 22» ^vn ^ z of the sliding mounting of a drive end of the rocking lever direct £. The driven end of the rocking straight lever 6 is rotatably articulated by a pin 13 on a drifting process device 15 guided by a linear guide 16. The pin 6 is the pivot point of the rocking lever and is accommodated in a housing 2. 14. The driven pin 13 has a stroke 2 corresponding to a stroke 8.

The device according to the invention is usable in mechanical engineering on technological equipment which continuously divides, marks, punches etc. with the production. At the same time it is applicable in other branches of the national economy where the described principle can be used, eg in printing, paper and electrotechnical industry.
