Description

The utility model relates to the technology of production of weights with a single-sided adhesive coating for balancing automobile wheels with a disk of alloy materials.

Balance weights are usually made by stamping or casting.

The closest analogue to the claimed utility model is a device for the production of balancing weights by stamping followed by gluing an adhesive tape (see patent US 6260929, B60B 1/00, 2001).

The known device is difficult to operate and maintain, has a high level of harmful hazardous production factors.

The objective of the utility model is to increase productivity, simplify technology and reduce the size of the production line.

The problem is solved due to the fact that the technological line for the production of weights in the form of truncated tetrahedral pyramids for balancing the wheels, containing means for forming weights and gluing adhesive tape, is made in the form of a conveyor containing rolled figured rolls combined in a sequential technological chain and driven into the movement of an electric drive with frequency regulation of the speed of rotation of the controlled shaft, and in the process chain at least two rolls for forming the transverse faces of the pyramid, at least two rolls for forming the transverse faces of the pyramid, at least one of which is the upper one, made with transverse grooves, a powder coating chamber material for a protective coating with its subsequent sintering, rollers for applying a double-sided adhesive tape, equipped with bearing rollers for feeding adhesive tape from the drum and a shaft with separation of sections for the formation of rolls of chopped ribbons.

Using the proposed production line will ensure the performance of all operations, from the supply of the workpiece to the receipt of finished products, on one automated production line, which allows to do without interoperational storage and transportation of workpieces.

In addition, it will ensure the continuity of the production cycle and the possibility of stopping / starting it at any time without economic losses and any additional preparatory operations.

The entire set of equipment can be installed in one room, and the production line can be serviced by one operator-adjuster.

The utility model is illustrated using the drawing, in which Fig. 1 shows a production line, and in Fig. 2, a balancing weight, which is a truncated pyramid with markings on the upper plane and applied double-sided adhesive tape on the lower plane.

The production line is a conveyor on which the stages of the production of weights are carried out. The mechanisms for performing the necessary operations at all stages have a similar design: the rolls are driven through an electric gear motor with a chain drive with frequency regulation of the rotation speed of the controlled shaft. All electric drive mechanisms are controlled by a programmable logic controller, which, together with low-current actuators, is mounted in a control electrical cabinet. The movement of the tape in the areas between the rolls is provided through the use of free-rolling rollers, since the distance between adjacent rolls does not exceed the length of the tape used. At the first stage, the rolls have a smooth surface, at the next - the lower roll is smooth, and the upper one is molded, depending on the stage of processing the tape.

Weights are made from an alloy of lead with the addition of antimony. The starting material is sheets with a thickness of 3 or 5 mm and a length of 1000 to 5000 mm, supplied in rolls.

Weights are produced in several stages.

At stage I, the tape is formed by rolling the roll 1 on smooth rolls 2.

At stage II, the sheet is rolled through rolls 3 to form the longitudinal side faces of the pyramid. Extrusion of each line of the side faces is carried out sequentially from right to left. Since the width of the sheet allows you to form up to 50 (depending on the width of the pyramid face) longitudinal blanks (without trimming) on one sheet, rolling each blank form causes the crowding out of excess material. Therefore, several consecutive rolls are used to compensate for the increase in the width of the tape during rolling, ensuring the absence of defects of the correct geometric shape of the truncated pyramid (burrs, sagging, etc.).

At stage III, the sheet is rolled through rolls 4 to form the transverse faces of the pyramid. The upper roll is made with transverse grooves.

At stage IV, a catalytic deposition of an anticorrosive coating (transparent or colored powder varnish) is carried out in chamber 5, followed by sintering at a temperature of 280 ° C.

In step V, a double-sided adhesive tape is applied while trimming in the longitudinal vertical plane of the molded sheet to produce tapes having a weight of one weight. To this end, an adhesive tape is supplied from the lower drum 6 through the guide rolls 7.

In step VI, rolls of cut tapes are formed on the shaft 8 with separation of sections for winding each roll individually. After that, each roll is placed in a separate box 9, which is then subjected to labeling and storage.
