Abstract

The invention relates to methods for manufacturing articles of wire porous material such as metal rubber (MR) and improves the productivity and quality of the product. The invention is carried out to obtain porous products from metal wire by shaping them from strips made of a single piece of wire. lengths using the cooler (transverse) method in under workers on a knitted transverse machine in a filling machine, and carried out the subsequent shaping of the workpiece by known methods, usually pu em winding tapes on the mandrel, subsequent laying preform into a mold corresponding to the shape and dimensions of the finished product, and its compaction. 4 il.

Description

The invention relates to the field of metal forming, in particular, to methods for manufacturing articles made of wire porous material such as metal rubber (MR), which is obtained by cold pressing of preformed deformed and laid into a wire blank.

The purpose of the invention is to increase labor productivity and product quality.,

FIG. 1 shows a device for implementing the described method — a functional diagram of a knitting machine with a material metering unit in FIG. 2 — a tape obtained by cooling from a piece of wire of a predetermined length in FIG. 3 and 4 — stages of final formation of the workpiece before placing it in the mold.

Knitted mapgan 1, which includes a carriage 2, which receives reciprocating movement through gear 3 from the drive with electric motor 4, is equipped with a photo sensor 5 mounted on bracket 6, which can be moved in the direction of carriage 2 along rod 7 and fixed to it is a screw 8. In the composition of the machine there is also the equipment 9 for controlling the electric motor of the drive 4. On the carriage 2 there is a plate 10 of opaque material intersecting the light beam of the photosensor 5 when the carriage 2 moves.

The material dispensing unit 11 comprises a pulse counter 12 and a driver (comparator) 13.

The fabrication of a tape from wire (blank) is carried out as follows.

With a known wire length per billet and wire consumption for a single carriage stroke, the required number of single carriage strokes to use a wire of a given length is determined and installed on the driver 13 (comparator), and the smaller wire carriage length (if any ) 5 is taken into account by moving the bracket 6 from the photo sensor 5 to the rod 7,

A well-formed billet is placed in a mold that is suitable in shape and size ready fy f. product, and pressed under a given pressure (for example, 500 kgf / cm). Other options are possible for the final shaping of the blanks depending on the configuration of the finished ™ 1Q HE product.

The use of the proposed method of manufacturing porous metal wire products will significantly simplify the technological process of manufacturing blanks of porous material, completely eliminate manual labor at the stage of

During the operation of the knitting machine, the plate Yu crosses at each course of the carriage 2 the light beam of the photosensor 5, and the electric pulses from it enter the counter 12 pulses. A close device (comparison device) 13 compares the number received by the pulse counter with the set one and gives their equality to: Ignap The motor control equipment 9 to switch off the latter. After that, the finished tape is removed and the cycle repeats.

The size B of the ribbon (Fig. 2) is set by the number of working needles on the knitting machine, and its thickness t, approximately equal to 10. "15 wire diameters, is provided by adjusting the machine. The length of 1 tape is not regulated,

Dp the final shaping of the workpiece tape is folded in half (figure 3), and then put on the mandrel (figure 4), after which the window

final shaping of the charge tube and increase labor productivity in this operation by 5-6 times, as well as improve the quality of products due to more uniform distribution of the wire in the workpiece.
