Field of the Invention The present invention relates to a surface processing apparatus for spraying a grinding material onto the surface of a workpiece such as a moving plate or wire to machine the surface of the workpiece.

2. Description of the Related Art Generally, in the manufacturing process of metal materials,
Since heat treatment is performed to improve the material associated with the forming, an oxide film is formed on the metal surface at that time. In particular, in the wire manufacturing process, the wire material that is the raw material is processed into a target wire diameter through a die.In this wire material manufacturing process, an oxide film is formed on the metal surface by the heat treatment performed at the material manufacturing stage or after the die processing. To be done.

Therefore, a surface processing step for processing the surface of the wire is required, such as removal of the oxide film formed by such heat treatment and formation of a surface underlayer as a step prior to the plating of the wire.

Conventionally, in these surface processing steps, a surface treatment is performed with a chemical such as hydrochloric acid. In the case of such chemical treatment, since the treatment effect depends on the chemical reaction rate of the metal surface and the chemical, the target of the metal surface to be treated, that is, the thickness and shape of the oxide film, the wire diameter of the wire, and the line speed It is necessary to adjust the appropriate reaction time depending on the difference. Also, usually store a large amount of chemicals in a large chemical tank,
Surface treatment is performed by passing a plurality of wire lines in parallel through a chemical tank.

In such a surface processing step, the surface processing is adjusted by the line speed of the wire and the contact time of the chemical.

However, surface processing using chemicals causes a chemical reaction with a metal and causes a chemical change with the lapse of processing time. Therefore, in order to maintain the chemical reaction, the chemicals are always replenished or replaced. Is required. Further, since the reaction product with metal and other impurities increase in the chemical tank, facilities and treatments such as regeneration of chemicals are required. In addition, strong acid etc. are often used for metal surface processing using this chemical, and it is often used by heating the chemical to increase the reaction rate with the metal, so there is no danger. Equipment for condensing and neutralizing the chemical vapor used is also required.

As described above, in the conventional metal surface processing, since the chemical reaction treatment with chemicals is used, it is not only a dangerous working environment, but also a large amount of wastes such as chemicals are generated. was there.

Therefore, in order to solve the problems of metal surface processing using chemicals, an air blast method of spraying an abrasive together with compressed air from a nozzle onto a workpiece to perform surface treatment or centrifugal force of an impeller is used. The shot blast method used is known.

However, in the metal surface processing using such an abrasive, when moisture or foreign matter is attached to the workpiece, the abrasive solidifies on the surface of the workpiece and becomes clogged in the processing apparatus. May occur or may have an adverse effect on the plating process in the subsequent process.

Further, when the blasting method is applied to a production line, continuous operation is generally performed. Therefore, a maintenance method such as equipment maintenance such as replacement of parts of a processing equipment or a cutting of a metal wire during manufacturing is established. I need to put it. In addition, the metal wire does not always flow in a stable state,
If necessary, it is necessary to change the operating conditions of the processing device based on the state. For example, the operation of the processing apparatus is stopped when abnormal deformation occurs, and the spraying force is adjusted due to the difference in the adhered state of the oxide film.

Further, the air blast method can concentrate and spray the abrasive material more efficiently than the shot blast method, but the relative alignment between the metal wire and the nozzle is important, and the nozzle is consumed. It is extremely difficult to align the nozzles in consideration of regular replacement of the product.
Further, generally, in a surface processing apparatus using an abrasive, abrasion is apt to progress in the spray nozzle and the like, and it is necessary to grasp this state and periodically replace it for preventive maintenance.

The clogging phenomenon can be prevented. Therefore, it is possible to improve the reliability of the metal surface processing apparatus 1 as a whole and manufacture a high-quality wire M.

Further, a metal material state detecting device 16 is arranged before and after the grinding box body 7. The metal material state detecting device 16 detects the metal wire rod state such as the deformation of the wire rod M by the two-dimensional cameras 16a and 16b.

For example, the wear of the nozzle 6 expands with the lapse of use time, but if the air flow rate and the amount of abrasive are constant, the inlet pressure of the nozzle 6 will increase as the wear progresses. It will decrease. By preliminarily grasping the relationship between the air flow rate at the wear limit, the amount of abrasive, and the nozzle inlet pressure, and storing this in a memory (not shown) of the life evaluation control device 24, the time of the nozzle 6 can be adjusted appropriately. The metal surface processing apparatus 1 can be replaced, and accidents and maintenance of the metal surface processing apparatus 1 can be achieved.
As a result, the reliability and maintainability of the processing device can be improved.

The second surface processing apparatus according to the present invention
An embodiment will be described.

The second embodiment is the same as the first embodiment.
While a processing unit consisting of one nozzle and a grinding box is used, two processing units are arranged in series along the metal wire.

For example, as shown in FIG. 5, the metal surface processing apparatus 1B of the second embodiment has two processing units 25.
Ba and 25Bb are arranged in series, and the processing units 25Ba and 25Bb each have a grinding ability of 100% with respect to the wire M, and the nozzle 6B as an abrasive ejection pipe.
a, 6Bb, and grinding boxes 7Ba and 7Bb in which these are accommodated and can be opened.

Therefore, normally, one of the processing units is operated to perform surface grinding.

As a result, the consumable nozzles 6Ba and 6Bb can be replaced without stopping the production line of the wire rod MB. Further, since the other nozzle in the operation stopped state can be maintained at any time, there is a margin in the maintenance plan. Further, it also serves as a backup in the event of a failure in one system.

In addition, usually, a plurality of wire rods MB usually flow through the production line at the same time, and it is a great loss to stop all the wire rods when one wire rod fails (breaks or the like). With the configuration according to the present embodiment, it is possible to recover the abnormal wire without stopping the normal line.

Specifically, the recovery work is performed in the following procedure. Here, it is assumed that the processing unit 25Ba is operating. (1) Wire Rod Cutting: The wire rod winding device 12B pulls out the wire rod MB from the processing units 25Ba and 25Bb. (2) Operation stop of wire rod winding device: The wire rod winding device is stopped when the end of the wire rod MB comes out of the grinding box body 7Bb. (3) Switching the processing device operation: The operation is switched from the processing unit 25Ba to the processing unit 25Bb, and then the processing unit 25Ba is stopped. (4) Wire rod set: The broken wire rod MB is pulled from the coil 12Bb on the material side, and the processing unit 25B is stopped.
Set to a. (5) Switching of processing device operation: Processing unit 25Bb
To the processing unit 25Ba, and then the processing unit 25Bb is stopped. (6) Wire rod setting: The wire rod set in the machining unit 25Ba is further pulled, and the machining unit 25 is in operation stop.
Set to Bb. (7) After passing through the two processing units 25Ba and 25Bb, they are connected to the broken wire section on the wire winding device 12Ba side, and the operation of the line is restarted.

As described above, the maintainability is excellent.

A third surface processing apparatus according to the present invention is also provided.
An embodiment will be described.

In the third embodiment, the nozzles of the first embodiment are fixedly arranged, whereas the nozzles are arranged so as to freely move back and forth with respect to the metal wire.

For example, as shown in FIG. 6, the processing unit 21C of the surface processing apparatus of the third embodiment has a grinding box body 7C.
A nozzle moving guide rail 26C is provided on the nozzle rail 6C, and a nozzle 6C having a nozzle roller 27C attached thereto is provided on the guide rail 26C so as to be able to move forward and backward. A stopper 26Ca is provided at the tip of the guide rail 26C, and the position of the tip of the nozzle 6C is uniquely determined by the structure of the nozzle 6C to which the guide rail 26C, the stopper 26Ca, and the nozzle roller 27C are attached. .

Therefore, the nozzle 6C, which is a consumable item, can be easily removed from the grinding box body 7C in the direction of the arrow and replaced, and also when it is re-installed, the nozzle 6C is attached to the metal wire M by the above mechanism. A reproducible setting of the tip of 6C can be performed.

As a result, the maintainability of the metal surface processing apparatus can be improved and the alignment can be facilitated when the nozzle 6 is replaced and restored.

The fourth surface processing apparatus according to the present invention
An embodiment will be described.

The fourth embodiment has a nozzle tip position fixing jig for positioning the tip of the nozzle.

For example, as shown in FIG. 7, a nozzle tip position fixing jig 28D is provided at the tip 6Da of the nozzle 6D used in the surface processing apparatus of the fourth embodiment.

The nozzle tip position fixing jig 28D is made of a rectangular parallelepiped metal block, through which the wire MD passes,
A workpiece through hole having a diameter larger than the diameter of the wire rod MD, for example, a wire rod through hole 28Da is bored on the center line in the longitudinal direction, and the four sides of the metal block have the length of the wire rod through hole 28Da. Nozzle insertion sockets 28Db into which the tips 6Da of the nozzles 6D are inserted are provided at positions that do not overlap each other along the direction. Further, an escape hole (not shown) for allowing the abrasive to escape is provided coaxially with the surface facing the nozzle insertion socket 28Db. Nozzle tips 6D are inserted into the four sockets 28Db, respectively, and the four nozzles 6D are fixed at a nozzle tip position fixing jig 28D with an angle of 90 °, and the nozzles 6D are wire rods. It communicates with the through hole 28D.

The material of the nozzle is not limited to metal and may be any wear-resistant material such as ceramics, and the nozzle tip position fixing jig is not limited to one formed by processing a block, but a plurality of jigs may be used. It may be formed by assembling members.

Therefore, the metal wire material M and the abrasive material are fed to the nozzle 6D.
The positional relationship with the tip 6Da of the nozzle is the most important factor for performing uniform surface processing, and the nozzle tip position fixing jig 28D uses the roller or the like to position the metal wire MD at the target position (center in this embodiment). The nozzle tip 6Da
Can be easily and accurately positioned in four directions simply by inserting it into the nozzle insertion socket 28Db of the nozzle tip position fixing jig 28D.

Further, since the jetting portion, which is the most worn out of the spraying portion, is a block, the wear allowance can be increased and the life of the consumable nozzle can be expected to be extended. As a result, a metal surface processing apparatus having high reliability and excellent maintainability is realized.
