JPS6026674B2 - Automatic shaping device for roll-shaped abrasive material - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic shaping device for roll-shaped abrasive material, and is characterized in that the roll-shaped abrasive material is automatically shaped while continuing polishing work.

That is, as shown in FIG. 3, if the polishing of the steel plate x is continued between the roll-shaped abrasive material 1 such as a buff roll and the backup roll 2, the roll-shaped abrasive material 1 will wear only inside the steel plate Unnecessary parts (shaded parts) are generated.

Then, as the polishing operation continues, the unnecessary portion of the roll-shaped abrasive material 1 comes into contact with the backup roll 2, polishing the backup roll 2, and at the same time, the steel plate is not polished.

Accordingly, when the roll-shaped abrasive material 1 as described above is worn out, the entire apparatus is temporarily stopped and the roll-shaped abrasive material 1 is removed.
It has been reshaped, installed and used again.

However, the polishing line has a series of processes such as washing, polishing, rinsing, and drying equipment, and it is not appropriate to stop all of these equipments. Furthermore, the roll-shaped abrasive material 1 has a considerable weight. Removal and installation are time-consuming.

The present invention is obtained by removing the momme point as described above.

As mentioned above, in the polishing of ball plates and the like, a line is constructed for a washing process, a polishing process, a rinsing process, a drying process, etc., and the present invention is used in the polishing process. The details will be explained in detail below with reference to the drawings.

A pipe 4 is rotatably provided parallel to the rolled abrasive material 1.

That is, the pipe 4 is supported by bearings 6 provided on both sides of the frame 5, and a bracket 8 is fixed to one end of the pipe 4. A piston rod 10 of a air cylinder 9 provided on the frame 5 side is mounted on the bracket 8. It will be worn. Further, inside the pipe 4, a shaft 12 having reverse male threads 11, 11' is provided at both end positions so as to be rotatable in the forward and reverse directions. That is, bearings 1 such as bearings provided at both ends inside the pipe 4
A gear 14 is fixed to one end of the pipe 3, and the gear 14 meshes with a gear 17 of a rotation shaft 16 of a forward/reverse rotation motor 15 provided integrally with the pipe 4 side. Next, a trowel arm 17 is provided at the center of the pipe 4 and protrudes in the direction of the rolled abrasive material 1, and a loft 18 is provided at the tip of the arm 17 to come into contact with the abrasion surface of the rolled abrasive material 1. Further, bosses 19, 19' having internal female threads are screwed into the reverse male threaded portions 11, 11' of the shaft 12. Furthermore, a slider 2 is attached to the pipe 4 at the reverse male screw portion 11, 11'.
0 and 20' are iron-plated, and the closest holes 21 and 2 provided in the pipe 4 are
1' and connected to 19 and 19', respectively. Next, from the sliders 20 and 20', arms 2 are respectively protruded in the direction of the rolled abrasive material 1, similar to the arm 17.
2, 22' are provided, and the roller 18 is provided at the tip thereof.
Grinding wheels 23, 23' are provided so as to be on the same line as
It can be rotated at high speed by motors 24 and 24' installed on the same level.

Furthermore, the pipe 4 is rotated toward the rolled abrasive material 1 side by the air cylinder 9, and the roller 18 and both grinders 23 are rotated.
, 23' are pressed against the roll-shaped abrasive material 1. 24 in the diagram
, 24' are bellows that cover the 4 parts of the pipe to prevent dust from entering the sliding surfaces of the sliders 20, 20'.

The grinders 23 and 23' are preferably made of a material having excellent hardness, such as a diamond cutter, and have a grinding effect on the side surface thereof.

In the present invention having the above-mentioned configuration, when polishing the roll-shaped abrasive material 1, the air cylinder 9 always uses the roller 18, the double grinder 23,
23' may be pressed against the roll-shaped abrasive material 1, and as shown in FIG. A cylinder 9 may be activated. In any case, when shaping the rolled abrasive material 1, the roller 18 and both grinding wheels 23, 213' are pressed against the rolled abrasive material 1 at a position that does not interfere with the polishing of the steel plate, and the shaft 12 is pressed by the motor 15. When the is rotated forward and backward, the bosses 19 and 19', sliders 20 and 20' and arm 2
Grinding wheels 23, 23' slide through 2, 22',
Unnecessary portions generated at both ends of the roll-shaped abrasive material 1 are removed by polishing.

These unnecessary parts are ground and removed by the roller 18 coming into contact with the worn surface of the roll-shaped abrasive material 1. Since the roller 18 and the grinding wheels 23, 23' are on the same line, the unnecessary parts are ground unduly deeply. It is controlled by the roller 18 and performs polishing in the same line as the polished surface of the steel plate 1 without creating a striped pattern on the steel plate 1. 3 is formed, and both ends of the roll-shaped abrasive material 1 are not placed on the backup roll 2 side to polish the backup roll 2, and the steel plate can be continuously polished. There is no need to stop the apparatus, remove the roll-shaped abrasive material 1, and shape it as in the conventional method, and it has an excellent effect.

The simple explanatory drawings show one embodiment of the present invention, and FIG. 1 is a side view of the external part, FIG. 2 is a plan view with a part of the pipe section cut away, and FIG.
The figure is a front view showing the wear process of the rolled abrasive material.
