SU140704A1 - Curved profile polishing machine - Google Patents

Description

Known machines for grinding and polishing curly products, in which as a tool for moving the abrasive belt, the envelope of two naravlyaet and one pressure roller.

A distinctive feature of the copying machine for polishing products with a curvilinear profile, mainly underwater wings of ships, is the use of a support-carrying abrasive tape support that receives a reciprocating movement along a transverse guide portal, moving along the workpiece fixedly mounted on the table. Such an embodiment of the proposed machine provides for obtaining on the surface of the mesh, which improves the quality of polishing.

The proposed machine also differs in that. that on the caliper coaxially with the pressure roller installed copy rollers, rolling in the process of work on the surface of the product, which plays the role of a copier. It gives the chance to polish curvilinear surfaces without specially made copiers.

The design and schematic diagram of the machine is shown in the drawing.

Said machine consists of a fixed table 1 on which the polished wing 2 is mounted and secured, and a movable portal 3 carrying the abrasive tape 4 on it as a working tool.

The wing is sucked using vacuum suction to the surfaces of the first lallets secured to the table.

Thus, o6pa30Nt, the wing is prepared for processing.

No. 140704-2 Table I, which is assembled from separate sections, is mounted on a concrete foundation 5. On both sides of the table there are rails 6, along which portal 3 moves.

In the transverse direction of the portal 3, the caliper 7 moves in a reciprocating motion with the aid of a screw pair driven by a reversible electric motor.

In the part of the support 7 on the carriage 8, which has the ability to move vertically relative to the support body, two copy rollers 9 and one pressure roller 10 are mounted.

During the movement of the slide across the wing, the copier rods roll over the wing surface, whereby the presser po, 1 10, located between the copier rollers, rolling along the wing profile contacts the moving forming strip 4 with the product, thus the surface is polished.

The pressure roller 10 is attached to the carriage 8 on an independent suspension, which allows you to adjust the force of the abrasive belt against the wing.

When the caliper is moved to the width of the wing, the portal 3 moves along the wing by an amount equal to half the width of the abrasive belt, therefore during the time that the portal has moved the entire length of the wing along the table /, each wing section will be processed twice.

The machine has a // mechanism that maintains a constant tension of the abrasive belt, as well as a cooling system (for working with waterproof abrasive belt) and an abrasive dust suction system when operating without cooling.

The machine control is remote from the central control unit 2.
