Abstract

A method for improving the surface treatment of an object, a wire roller, and an application thereof are provided.
According to the invention, the method is used for surface treatment of an object (7), bringing a wire roller (15) into contact with the object 7 and applying a hit or hammer impact. The wire roller (15) partially rotates (8), partially pivots (12), and partially moves across the object (7) on the conveyor belt (11). As a result, an effective and completely uniform treatment (dropping and cleaning) of the surface covering including the oxide layer is ensured not simply by the polishing or cutting treatment but by simply the impact pressure. The rotating wire roller (15) bounces back slightly at the time of impact, otherwise it can remain in the same position due to the centrifugal force and the engagement between the wire end and the adjacent stay (4). A roller comprising wire elements (1, 2, 3) mounted on the stay (4) can be advantageously used.

Description

  The present invention relates to a method for surface treatment of an object preferably placed on a conveyor belt for the purpose of being accelerated by a wire on one or more rotating wire rollers, and a wire roller for carrying out the method, And its use.

  This kind of surface treatment is performed by various methods and various tools. When cutting an object, it is necessary to use an abrasive or scrubbing tool to clean the surface by removing both the coating and a portion of the object.

  However, this removes more or less useful material, and there is a risk of different removal depending on the shape and type of material.

  In order to avoid these disadvantages of the cutting process, it is known to polish the surface with a roller having a plurality of wires of plastic or metal. These wires act as bristles, but can only remove to a limited extent fixed deposits such as oxide layers.

  Further, DE102004029204, US3958294 and GB1537440 disclose wire rollers, all of which are composed of a plurality of stays on which a wire ring portion provided on one wire can rotate. When rotating, the wire rotates and comes into contact with the surface of the object by centrifugal force.

  The free part of the wire that handles the object is common to these known tools in that it can be rotated during processing, and rotates in reverse when the object is struck. This means that the object is exposed to different impact pressures depending on the reverse rotation of the generated wire and the elasticity of the wire itself.

  The object of the present invention is to improve the surface treatment.

  Improved surface treatment, according to the present invention, each wire roller is rotated about a shaft extending radially from a swivel shaft that swivels, and the swivel shaft and wire roller are simultaneously moved laterally with respect to the conveyor belt. And by using a method in which the object is treated from all sides with a constant impact pressure from the wire on the wire roller.

  The method is incredibly simple to remove both non-uniformly distributed coatings such as soft shells and fixed smooth coatings such as oxide and paint layers and burrs. Bring impact.

  Apart from the removal of the coating, the method has no effect on the object since it is left removed without damage. Therefore, “inox” can be deburred without damaging the protective sheet. Furthermore, galvanized objects can be deburred without removing or damaging the zinc layer.

  As stated, during the combined movement consisting of rotation, swiveling and transverse movements performed by the wire roller, the object is processed such that the passage is completely uniform, so the processing is quite uniform. Is very important especially when the method is used for deburring.

  As described in claim 2, when a spring wire is used, the effect is great due to inertia that causes a desired impact pressure when the wire hits an object.

  As claimed in claim 3, when the wire is curved to bend around the center in the rotational direction, an advantageous impact angle is achieved, thereby achieving a maximum impact pressure. When winding a wire to form a loop, the wire can be attached to a roller stay, and individual wire turns impart advantageous damping to the wire due to friction between the turns. After installation, the tail portion of the wire provides additional inertia that improves shock pressure and handling due to centrifugal forces that affect the wire as well as the wire extension that presses adjacent stays. It also creates a good installation position for the wire part to be used.

  Thus, the wire extension prevents the wire from moving backwards during rotation, thereby increasing the impact pressure effect.

  As described in claim 4, when this method is applied to remove surface coatings, an effective and very good treatment is achieved.

  As claimed in claim 5, when the method is applied to improve adhesion, it ensures a uniformly treated surface with uniform adhesive properties.

  Finally, as claimed in claim 6, it is advantageous to apply the method to impact hardening, strain hardening of metal objects, thereby increasing the resistance in use.

  The method of the present invention will be described below with reference to FIG. FIG. 1 shows the principle of surface treatment of a plurality of objects 7. Object 7 can be a metal or plastic object that is subjected to surface removal, deburring, surface hardening, or otherwise subjected to impact pressure applied by the wire It is.

  The objects 7 are preferably arranged on the conveyor belt 11. The conveyor belt 11 can be a magnetic belt or a vacuum belt.

  The object 7 moves inward below the plurality of wire rollers 15. In the example, six wire rollers 15 are provided. Each roller 15 is attached to a rotating shaft 6. Preferably, as indicated by the arrow 8, the adjacent wire rollers 15 are rotated in the opposite direction.

  The roller 15 disposed in the radial direction is attached to a turning head that turns around a vertical axis 13 as indicated by an arrow 12.

  Finally, the swivel head with the roller moves across the belt 11 with the object 11 as indicated by the arrow 14 at the bottom of the figure.

  Therefore, the processing of the object 7 is a combination of three movements. That is, a partial swiveling motion of the individual wire rollers 15, a partial rotational motion of the shaft 6 with the wire rollers 11, and finally a reciprocating motion of the device relative to the conveyor belt 11.

  This ensures uniform and uniform processing of all objects 15 on the side surfaces as well as the edges and surfaces. These may extend at the same or different degrees.

  Now, the wire roller of the present invention will be described.

  As shown in FIGS. 2 and 3, the wire roller 15 is configured based on a plurality of flanges 5 between the plurality of stays 4, and the stays 4 are attached so as to extend in parallel to each other. As shown in FIG. 3, the stays are arranged around the flange 5 at equal intervals.

  A plurality of wire elements are fitted on these stays 4. The wire elements are bent uniformly and are shaped to form one wire 1 for processing the object, as will be described later.

  FIG. 3 shows the actual shape of the wire element, bending the wire to form a loop 2 through which the stay 4 can extend. The wire element is adapted to be pivotable around this stay.

  The free end 1 of the wire is curved so as to point forward in the direction of rotation 8, as shown in FIG.

  As shown in FIG. 3, the opposite end portion of the wire after the ring portion 2 is configured as an end portion 3 that extends between the ring portions 2 and engages with an adjacent stay 4. This ensures that the wire elements 1, 2, 3 are in the proper position while the roller is rotating about its central axis 6.

  The wire element is shown in FIG. FIG. 4 shows the position of the wire before hitting the object 7.

  At the same time as the roller rotates in the direction of arrow 8, the roller pivots around the object 12 and / or the object 7 is moved under the roller, for example on the vacuum belt 11.

  When the wire end portion 1 hits the object, the rearmost portion of the wire 3 engages with the adjacent stay 4, so that the wire 1 is fixed at the indicated position, so that it hits with a constant force and hits the object. The

  While it is advantageous to use a spring wire that is wear resistant and has suitable elasticity, other materials such as plastic wire may be used.

  The diameter of the wire can be, for example, about 2 mm. The free end can be about 100 mm, for example, and the rear end 3 can be about 60 mm, for example. Other dimensions may be adopted as long as the mutual ratio basically corresponds to this.

  At the same time as the wire bounces as indicated by arrow 9, the wire may be optionally moved a short distance around stay 4 as indicated by arrow 10.

  Immediately after this, the spring element returns to the start position as shown in FIG. 4 due to centrifugal force, so that the wire is in the same position at the next impact on the object 7.

  Since it is stopped by the adjacent stay 4, as shown in FIGS. 3 and 4, it is ensured that all the wires are in the same position during the rotation.

The present invention will be described in detail with reference to the drawings, which are as follows.
Fig. 2 shows a system for performing the method as seen from above. The longitudinal cross-sectional view of a wire roller seen from direction II-II of FIG. 3 is shown. Fig. 3 shows a cross-sectional view of the wire roller as seen from the direction III-III in Fig. 2. One wire and movement during operation are shown.
