JPS61206557A - Deflashing method - Google Patents

Abstract

PURPOSE:To execute automatically a deflashing operation as a continuous operation and to lessen manpower by disposing a molding machine and rail members which arrive at the position right under the trimming punch of a trimming press machine. CONSTITUTION:A product 22 having a flash, when taken out of the molding machine 1, is imposed on a trimming die 7 which is held stopped at the left end of the rails 4a, 4b. The operator presses an operation button g1 thereafter. An air motor 14 is then operated to slide a die base 6 toward the trimming press machine 2. The motor 14 is stopped when a limit switch 17 is tripped right under the trimming punch 2a. A clamping claw 19a descends to press and fix the die base 6 onto frame. The trimming punch 2a descends to press the flashed product in the trimming die 7 when an operation button g2 is pushed. The deflashing is thus executed. The production which is completed of the deflashing drops downward by passing through the inside of a trimming base 7.

Description

[Detailed description of the invention] The present invention relates to an automatically performed deburring method.

Conventionally, to remove burrs from a molded product, the molded product taken out from the molding machine is transported to a trimming press machine, placed on a trimming die of the machine, and the trimming press machine is operated to remove burrs. Workers were required to transport and operate the trimming press.

The present invention proposes a new deburring method that enables the current work to be performed as an automatic continuous work and contributes to labor saving for workers. A rail member is provided so as to reach directly below the trimming punch of the trimming press machine from a position adjacent to the rail member, and the trimming die is provided so as to slide back and forth through the rail member, and at the sliding end, that is, the molding On the machine side, the molded product taken out from the molding machine is placed on the trimming die, while on the trimming press machine side, directly below the trimming punch, the sliding trimming die is clamped on the rail, and the trimming die is also clamped on the rail. The trimming punch is lowered in conjunction with the casting so that cast stripping is performed as an automatic continuous operation.

Hereinafter, an example of implementing the present invention will be described based on the accompanying drawings.

FIG. 1 is a schematic front view of the entire device, FIG. 2 is a plan view taken along line X-X, FIG. 3 is a plan view taken along line X-X, and FIGS. 4A and 4B are action explanatory views.

2 is a molding machine, 2 is a trimming press machine, and 3 is a rail member (shuttle conveyor) disposed between the two, and both end edges of the rail member are connected to the molding machine 1 on the molding machine 1 side. At an adjacent position, on the other hand, on the side of the trimming press machine 2, the length is designed to reach just below the trimming punch 2a.

The rail member 3 has a configuration in which rails 1lz4a and 4b each having a U-shaped cross section are arranged opposite each other at regular intervals in the horizontal direction on pedestals 3a and 3b of a constant height, and inside the rail there are rails 1lz4a and 4b with an inverted-shaped cross section. Four wheels K provided on both sides of the mounting stand 5 are fitted.

Reference numeral 6 denotes a mold stand which is elastically attached to the four corners of the mounting stand 5 via springs S, and a trimming diamond is fixed onto the stand.

On the other hand, 8a and 8b are the above-mentioned mounting stand 5 v-zlzJa, 4b
These chenos are for sliding along the rails 4a and 4b, and one end is attached to the front side of the stand 5 and the other end is attached to the rear side. Rotating shafts 9a and 9b are rotatably supported in a straddling state.
Renuufrocket lOa, 1f mountain, which rotates as one with
11a and 11b, and guide the inside through guide sprockets 12 and 18 into the pedestal leg, and connect the pedestal leg 3a.
It is engaged with a drive sprocket 15 attached to the end of the rotating shaft of an air motor 14 disposed inside the air motor 3b.

16 and 17 are limit switches for stopping the table 5 which slides back and forth on the rails 4a and 4b driven by the air motor 14, and 18 is an operation switch provided on the molding machine 1 side. It is a board. In addition, in the trimming press machine 2, when the holder 5 is stopped by the operation of the limit switch 17, a clamp claw 19a% is used to fix the mold holder 6 on the holder 5 at the exact position at that time.
Clamp claws 19b are provided at both side positions of the table base 20, that is, clamp claws 19a are provided downwardly from both side positions of the table base 20 by the operation of air cylinders 21a and 21b, respectively.
, 191), the filter membranes of the clamp claws 19a, 19b are fixed to the side edges of the trimming dia by pressurizing them.

Next, to explain the operation, as shown in Fig. 4, the operator operates the molding machine 1 and takes out the product 22 (with cast-stretching) obtained from the molding machine 1.
It is placed on the trimming dial that is stopped at the left end of a and 4b, and when the placement is finished, the operation button r is pressed. As a result, the air motor 14 is driven, and the chinos 8a and 8b are rotated in the direction of the arrow (arrow) to slide the mold table 6 toward the trimming press machine 2, and the trimming punch 2
The air motor 14 is stopped by kicking the limit switch 17 just below a, and the clamp claws 19a, 191) are lowered at the stop position to press and fix the mold table 6 on the placing table 5. .

When the fixing is completed, the operation button p is pressed, and the trimming punch 2a instantly descends and deburrs are performed by pressing the casting product inside the trimming diamond from above. The finished product passes through the inner hole of the trimming dia and falls downward. Incidentally, the falling products are taken out to the outside at any time via a downwardly disposed interior or chute (none of which is shown).

Next, as the trimming punch 2a rises, the shift lamp claws 19a and t9b are released, and the air motor 14 is driven in reverse to slide the mounting table 5 in the direction of the arrow (white). Then, the IJ Mitsutwitch 16 is pressed to stop the driving of the air motor 14, and at this position it is time to take out the next product, and the following steps are repeated in the same manner.

In the above embodiment, the operation of the trimming press machine 2 is controlled by the operation panel 1.
8, the air motor 14 is stopped by the operation of the IJ switch 17, and the clamp claws 19a and 19b press and fix the mold base 6. The above operation and the following steps can be performed automatically, and in the present invention, they can be performed continuously by automatically sliding the trimming die back and forth on the rail. Become something.

The present invention is configured as described above, and has a molding machine 1.
On the side, the worker simply places the cast-covered product from the molding machine on the trimming die, and the rest is automatically deburred, thus eliminating the need for conventional transportation and trimming. This contributes to labor saving and efficiency by eliminating the need for workers to be placed in the press machine. Note that several trimming press machines can be arranged and operated by one person, and in the case of different types of products, the trimming dies that slide on the rails are made to be different as appropriate. In addition, in the present invention, the use of an air motor as the driving source for the sliding trimming die not only allows air to be easily obtained as a power source at the forging site, but also for the safety of hot cast products. However, it is within the scope of the present invention to use electricity or hydraulic power as a driving source.
