Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a long continuous body that can efficiently perform polishing, deburring, scale removal, etc., without cutting a long continuous body such as a chain. And a barrel processing method.

(Prior art) Conventionally, in the case of polishing a long continuous body such as a chain, since there was no appropriate polishing device, it was necessary to rely on manual labor, or cut the continuous body into short lengths and barrel-processed. Thereafter, a method of rejoining is adopted.

(Problems to be Solved by the Invention) However, according to the above-described conventional methods, there is a problem that all of them take time and labor and the efficiency is low, and continuous work is also difficult.

The present invention has a basic object of solving the above problems, without cutting a long continuous body, polishing as it is,
An object of the present invention is to provide a processing method capable of performing processing such as deburring, scale removal, and removal of an oxide film.

(Means for Solving the Problems) In order to achieve the above-mentioned object, the present invention provides a vibration barrel tank in which a uniform small-diameter hose is arranged in multiple stages and / or multiple and spirally from a work loading port of a vibration barrel processing machine. The long continuous body is fed into the hose, and while the long continuous body is transferred in the hose by the operation of the barrel processing machine, barrel processing is performed, and the long continuous body is sent out from the workpiece discharge port. is there.

The above-mentioned vibration barrel processing machine may be one in which hoses of uniform small diameter are arranged in multiple stages and spirals, one in which multiple hoses are arranged in spirals, or one in which multiple hoses are arranged in multiple stages and spirals. .

The workpiece loading port and the workpiece discharge port of this barrel processing machine may be provided at appropriate places in the processing machine. For example, in a processing machine in which hoses are arranged in multiple stages in a double configuration, the hose is continuously connected to the hose. A workpiece loading port and a workpiece discharging port are provided at the upper part of the barrel processing machine.

In addition, various types of long continuous bodies to be provided for processing are conceivable, such as chains, punched strips,
Wires and the like can be mentioned.

In addition, when the long continuous body has a small self-propelling force in the hose like a wire rod, it is desirable to transfer the inside of the hose by applying a propulsion assisting force in the transfer direction from outside the barrel-evil machine. .

This assisting force can be achieved, for example, by installing a drawing device that pulls the continuous long body with a predetermined force in front of the barrel processing machine.

In addition, when the long continuous body has a large self-propelling force like a chain and moves in the hose at a speed higher than desired and does not allow sufficient barrel polishing time, it is transferred from outside the barrel processing machine. It is desirable to provide a propulsion restraint force opposing the direction.

As a method of applying this suppressing force, for example, it is achieved by installing a roller or the like that applies a predetermined resistance (to the progress) to the long continuous body behind the barrel processing machine.

(Operation) According to the present invention, the long continuous body is fed into the hose constituting the vibrating barrel tank from the workpiece loading inlet, and advances while being barrel-processed in the hose.

The part which has progressed through the hose of a predetermined length and has been barrel-processed is sequentially sent out of the barrel processing machine from the workpiece discharge port, and the long continuous body is continuously barrel-processed.

Further, if a propulsion assisting force is applied to the long continuous body from the outside of the barrel processing machine in the transfer direction, the continuous body having a small advancing force can be transferred through the hose at a desired speed.

In addition, if a long continuous body is provided with a propulsion restraining force opposing the transfer direction from outside the barrel processing machine, it is possible to perform sufficient barrel processing by suppressing the transfer speed even for a long continuous body having a large advancing force. It becomes possible.

Embodiment 1 Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

FIG. 1 shows a chain A which is a workpiece (long continuous body), in which a mild steel wire is cut and bent to be joined to each other, and its end faces A1... A1 are welded to form a continuous body.

In this chain A, it is necessary to remove scales and oxide films generated during welding, but polishing may be required in some cases.

FIGS. 2 and 3 show a front view and a plan view of a multi-stage vibrating barrel processing machine 13 used in the present invention, and a hose having a uniform small diameter is concentrically arranged between an inner cylinder 1 and an outer cylinder 2. 3a (outer processing tank) and hose 3b (inner processing tank) are spirally wound in multiple tiers inside and outside in upper and lower stages to form a barrel tank 3, and a metal fitting or space 4 is filled with plastics. The barrel tank 3 and the inner and outer cylinders 1 and 2 are fixed. A vibration motor 6 having a pair of eccentric weights 5a and 5b is vertically mounted above the inside of the inner cylinder 1, and these devices are mounted on a base 9 by a number of springs 8 and 8 together with a flange 7.
Hang on top. In addition, a workpiece discharge port 10 is provided at the upper end of the outer processing tank 3a, and an inner / outer processing tank joint 11 is provided in this portion, and the uppermost part of the outer processing tank 3a and the uppermost part of the inner processing tank 3b are connected. A workpiece inlet 12 is provided in the inner processing tank 3b for joining.

FIG. 4 shows an example of a machine tool group using the barrel processing machine 13. This figure and the whole operation will be described as follows.

The continuum of the chain A formed by welding by the welding machine 21 is slackened in the adjusting box 23 so as to correct an error in the speed between the welding speed and the grinding machine. The chain A that has exited the adjusting box 23 is introduced into the processing machine 13 through the rollers 24 through the workpiece loading port 12 shown in FIGS. Processing machine 13
The inside is filled with a medium, and the medium is caused by vibration generated by operating the vibration motor 6 in FIG.
The media flows spirally in the order of 14a, 14b ... 14, and reaches the top (end) 29 of the outer processing tank.
From 11, the inner processing tank 3b is re-entered and circulates in the same path as before. Accordingly, the chain A introduced from the work loading port 12 is propelled in the direction of the arrow 16a by the movement of the medium, and moves below the upper part of the inner processing tank 3b and further above the lower part of the outer processing tank 3a. The polishing action is performed by the movement of the mass during the movement in the tank, and the polishing action is guided outward from the workpiece discharge port 10. The chain guided to the outside passes through rollers 25a and 25b, and then a rust preventive liquid tank 26 containing rust preventive liquid.
After being introduced into the
It is wound up.

Large abrasives to be charged into the processing machine have good deburring effect and efficiency in removing scale and oxide film, but the inner surfaces of holes such as the gap A2 of the chain A shown in FIG. 1 cannot be processed. Therefore, when the inner surface of the hole needs to be polished, a polishing material having a size enough to pass through the hole is mixed and polished. Although it is possible to work with only a small abrasive, it is better to mix them because the efficiency of deburring the outer surface is poor. The abrasive discharge hole 15 is used when the abrasive in the processing tank is replaced.

Second Embodiment FIG. 5 shows a layout of a group of machine tools according to another embodiment, in which a wire rod B is used as a long continuous body.

This embodiment also has the same processing line as the previous embodiment, but the welding machine 31 is a welding machine for the wire rod B, and the arrangement of each processing machine is slightly different. That is, the next drawing device 30 of the barrel machine 13 is installed, and the rollers 25a and 25b are next to the drawing device 30.
Are installed, and then a rust preventive liquid tank 26 and a winding device 27 are sequentially installed.

Explaining the operation of the machine tool group, a pulling device 30 applies a forward pulling force to the wire rod B, which is a long continuous body, to smoothly transfer the wire rod B having a small self-running force. Other operations are the same as those in the above embodiment.

Although the first and second embodiments have been described using the multi-stage tank, the same processing can be performed without any problem even if the processing machine is a non-multi-stage tank or a non-multi-stage tank.
There is a disadvantage that the polishing time is shortened.

(Effects of the Invention) That is, according to the present invention, a long continuous body is supplied from a work loading port of a vibration barrel processing machine in which a hose having a uniform small diameter is arranged in multiple stages and / or multiple and spirally as a vibration barrel tank. The long continuous body is fed into the hose, and the long continuous body is barrel-processed while being transported within the hose by the operation of the barrel processing machine, and is sent out from the workpiece discharge port. By using this method, a continuous body such as a chain can be directly connected to a molding machine and polished continuously, which has a remarkable effect on labor saving, labor saving and improvement in processing efficiency.

In addition, since the passing speed of the long continuous body in the barrel processing machine is controlled, polishing is performed according to the material and shape of the long continuous body. There is an effect that a good polishing result can be obtained.
