Abstract

A double-tension control system of a multi-wire sawing machine for cutting wires comprises a machine frame. Wiring mechanisms, winding-up and paying-off mechanisms, wiring detecting mechanisms, and two tension mechanisms which are arranged symmetrically and two sets of guiding passing wheels are arranged on the machine frame, wherein all the mechanisms are two sets, the two ends of a steel wire for cutting are respectively wound on winding rollers of the two winding-up and paying-off mechanisms, a tension hindering wheel is arranged between the two tension mechanisms of each set, the tension hindering wheels are installed on output shafts of motors, and the motors are fixedly connected to the machine frame through supports. Due to the fact that the tension hindering wheels are provided, during running, the steel wires have enough tension in a cutting zone, tension of the steel wires in other zones can be correspondingly reduced, cutting quality is guaranteed, at the same time, the double-tension control system plays an effective role in protecting each part of the cutting machine, so that parts wound by the steel wires do not need to undergo large tension, and the service life of a device is prolonged.

Description

Two tension control systems of multi-line cutting machine line of cut

Technical field

The utility model relates to a kind of two tension control systems of multi-line cutting machine line of cut.

Background technology

Multi-line cutting machine is the capital equipment of cutting silicon materials, and in cutting process, the steel wire high-speed motion cuts workpiece.Existing multi-line cutting machine has the identical unwrapping wire of structure and take-up, be commonly referred to the retractable cable roller, in take-up zone and unwrapping wire zone two groups of steel wire tension force control and regulation devices are arranged all, during cutting steel wire leave the unwrapping wire zone enter take-up when zone in the middle of through cutting area, form many lines of cut at the cutting area steel wire around one group of cutting roller silicon materials cut.Existing equipment steel wire is identical with the tension force in retractable cable district at cutting area, and the centre does not have tension force to intercept mechanism.In fact steel wire is bigger at the tension force that cutting area needs, and other zones also do not require bigger tension force, and steel wire inevitably impacts associated mechanisms in that All Ranges tension force is identical, has increased the requirement of associated components to intensity, has influenced service life.

Summary of the invention

The purpose of this utility model provides a kind of obvious tension force to steel wire and forms obstruct, makes cutting area steel wire tension force greater than two tension control systems of the multi-line cutting machine line of cut of other zones, assurance cut quality, prolongation service life of equipment, overcomes the deficiencies in the prior art.

Two tension control systems of multi-line cutting machine line of cut of the present utility model comprise frame, are provided with wire-arranging mechanism, retractable cable roller mechanism, winding displacement testing agency, symmetrically arranged two cover tension mechanisms and guiding third wheel in frame; Described each mechanism and each third wheel are two groups, and the two ends of incisory steel wire are respectively on the winding roller in two groups of retractable cable roller mechanisms; Be provided with tension force between the two cover tension mechanisms in every group of mechanism and intercept wheel, tension force intercepts wheel and is installed on the output shaft of motor, and motor is fixedly connected on the frame by support.

Two tension control systems of multi-line cutting machine line of cut of the present utility model; owing to there is tension force to intercept wheel; steel wire has enough tension force at cutting zone during operation; the tension force of other regional steel wires can correspondingly reduce; when guaranteeing cut quality each parts of cutting machine have also been played effective protective effect; unlikely all bear bigger tension force around the steel wire parts, improved the service life of equipment.

Description of drawings

Fig. 1 is the structural representation of one group of line of cut coil winding system wherein in the utility model specific embodiment;

Fig. 2 is A-A cross-sectional schematic shown in Figure 1;

Fig. 3 is the structural representation that two groups of line of cut coil winding systems are combined to form take-up and unwrapping wire in the utility model specific embodiment.

The specific embodiment

As shown in Figure 1, 2: 1 is frame, in the bottom of frame 1 wire-arranging mechanism 2 is installed, and the moving body upper support in the wire-arranging mechanism 2 has retractable cable roller mechanism 3, can drive moving body during wire-arranging mechanism 2 actions and move back and forth retractable cable roller mechanism 3 reciprocating action thereupon.The front end of retractable cable roller mechanism 3 has winding roller 4.

Be provided with winding displacement testing agency 15 in frame 1, winding displacement testing agency 15 comprises two measuring rolls that be arranged in parallel, measuring roll is installed in and can does on the installing plate of swing with respect to frame 1, and is furnished with inductive head, between steel wire 5 that winding roller 4 twines is through two measuring rolls.When steel wire has skew, touch one of them measuring roll, make the installing plate swing, simultaneously by the inductive head output signal, adjust wire-arranging mechanism by control device, guarantee the winding displacement quality.

Be symmetrically arranged with two groups of tension mechanisms 6 in frame 1, as shown in Figure 1: tension mechanism 6 comprises cylinder, be connected by bearing pin between the termination of cylinder and the frame 1, be connected by bearing pin with the draw bead middle part with the piston rod external end head that cylinder matches, be connected by bearing pin between draw bead one end and the frame 1, the other end of draw bead is equipped with first straining pulley 12.13 is second straining pulley, identical with first straining pulley 12 through the mounting structure of two straining pulleys 13, no longer describes in detail.

As shown in Figure 1, 2: above frame 1, by link first third wheel 10 and second third wheel 11 are installed, between first third wheel 10 and second third wheel 11, be provided with tension force and intercept wheel 9, tension force intercepts wheel 9 and is installed on the output shaft of motor 8, motor 8 is installed on the frame 1 by support 7, and motor 8 is the servomotor that joins with electric control gear.

As shown in Figure 3: the retractable cable mechanism of cutting machine has two groups, and every group all can be used as take-up mechanism or payingoff mechanism, and its structure is identical.The centre is cutting area 14, and the two ends of steel wire 5 are respectively on the winding roller 4 of wire-wound in every group, middle arrange at cutting area 14 places cutting roller twine, form many lines of cut.

As shown in Figure 3: during work, the right side is the unwrapping wire part, the left side is the take-up part, after coming out, pass through successively the winding roller of steel wire 5 in the unwrapping wire part on right side between two measuring rolls in the winding displacement testing agency 15, first third wheel 10, first straining pulley 12, tension force intercepts wheel 9, second straining pulley 13, second third wheel 11, enter cutting area 14 then, after coming out, cutting area 14 enters the take-up part in left side, successively through second third wheel 11, second straining pulley 13, tension force intercepts wheel 9, first straining pulley 12, first third wheel 10, between two measuring rolls in the winding displacement testing agency 15, be wrapped in then on the winding roller 4 in left side.Owing to all have the tension force that is connected with motor 8 to intercept wheel 9 in left and right part, the steel wire tension force of controlling in the cutting areas by motor 8 during operation, make the steel wire of cutting area that enough tension force be arranged, steel wire tension force outside the cutting area can reduce relatively, both guaranteed cut quality, make other zones stressed less around the steel wire parts again, the service life of having improved associated components.
