Description

[Detailed Description of the Invention] Conventionally, the die casting industry has focused on mass production and saving labor costs in order to reduce production costs. First, the punching process using a press after molding required manual labor, and the initial objective was difficult to achieve because the molded parts were fed in, removed, and burred removed by hand. I felt that it was very inconvenient to manufacture die-cast products.

The present invention relates to an automatic press for punching that eliminates these inconveniences and allows forming, punching, and product sorting burr removal to be performed as a series of automatic assembly operations, eliminating the need for human labor. .

That is, the present invention is a press in which an upper mold and a lower mold are provided above and below a gate-shaped frame, and the lower mold is mounted on a lower mold mounting board that is movable by a roller guide and a slide cylinder provided on a pedestal below the frame. installation,
The deburring cylinder with a brush and a push-out plate at the tip and the take-out cylinder with a brush and a take-out plate at the tip operate in opposite directions, with the upper surface of the lower mold being deburred and the push-out plate being used, and the upper surface of the lower mold mounting plate being operated by the take-out plate. To make it possible to take out the product, the deburring cylinder is placed above and parallel to the take-out cylinder on the back side of the frame, the product chute is placed below the take-out cylinder, and the burr chute is installed diagonally on the opposite side from the product chute. , Auxiliary burr chute is installed on both sides of the lower mold mounting plate in an oblique manner so that the burr chute side is lower, and the product taken out from the molding equipment by the automatic take-out device is placed on the lower mold which is moved by a slide cylinder. The punched product is dropped onto a product chute by a take-out plate in correspondence with the upper mold, and the remaining products are dropped onto a burr chute by an extrusion plate and sent to the next process.

When using, install the mounting base 21 and the upper mold mounting board 2.
When the lower die 9 and the upper die 27 are fixed to the lower die 9 and the upper die 27, respectively. When pressed, the operating plate 16 hits the limit switch 20 and the slide cylinder 17 moves to the control box 41.
The process is temporarily stopped and the state shown in FIG. 4 is reached, and the semi-finished product 43 is placed on the lower mold 9 by an automatic feeding device or the like. Then, when the slide cylinder 17 moves in one direction for a certain period of time and stops, the control box 41 operates the slide cylinder 17 in the opposite direction and moves it back to its original state. The protruding plate contacts the limit switch 20, stops the movement of the lower mold mounting plate 13, and sets the lower mold 9 at the molding position.

On the other hand, in conjunction with the operation of the limit switch 20, the hydraulic cylinder 22 is operated to lower the slide 23, and the lower die 9 and the upper die 27 punch out the semi-finished product 43, and the product 44 is placed on the lower die mounting board 13. The other residual products 45 that have been removed are left as they are on the upper surface of the lower mold 9.

After the punching process is completed in this way, the slide 23
When the rises, the control box 41 is activated by the connecting rod 24.
In conjunction with this, the operation of the hydraulic cylinder 22 is stopped, and at the same time, the deburring cylinder 31 and the take-out cylinder 34 are activated. First, deburring cylinder 31
The brush 32 and extrusion plate 33 are pushed out to push the residual product 45 on the lower mold 9 and dropped by the burr chute 39, and the take-out cylinder 34 is pushed out by the brush 35.
Then, the take-out plate 36 is returned to its original position from the burr chute 39 side, and the product 44 on the lower mold take-out board 13 is dropped onto the product chute 37.

In this way, the product 44 and the residual product 45 are swept away from the lower mold 9 and the lower mold removal board 13, respectively, and the original state is returned to the original state in one reciprocating motion, and the deburring cylinder 3
1 and the take-out cylinder 34 stop operating, resulting in the state shown in FIG.

Lower die mounting board 1 with slide cylinder 17 again
3 is extruded, the semi-finished product 43 is placed on the lower mold 9, and the same process as described above is repeated to continuously perform processing one after another.

Then, the product 44 and the residual product 45 are completely separated and sent separately to the next process via each chute.

Incidentally, the burnt material scattered during punching falls from the overflow auxiliary burr chute 38 onto the second burr chute 39 and is sent to the next process.

Furthermore, drawings of wiring for each electrical system and hydraulic connection piping in the present invention are omitted.

As described above, the present invention provides a press in which an upper die 27 and a lower die 9 are provided above and below a gate-shaped frame 1 to enable punching.
The lower mold 9 is mounted on the mounting base 21 installed on the lower mold mounting board 13 which is movable with the slide cylinder 17.
, and reverse the movements of the deburring cylinder 31 with the brush 32 and extrusion plate 33 at the moving tip, and the take-out cylinder 34 with the brush 35 and take-out plate 36 at the moving tips, and remove the upper surface of the lower mold 9 with the brush 32 and the bottom. A deburring cylinder 31 and a take-out cylinder 34 are provided parallel to each other on the back side of the frame 1 so that the upper surface of the mold mounting board 13 can be discharged with a spring 35, and a product chute 37 is installed.
A burr chute 39 is provided diagonally below the take-out cylinder 34, and a burr chute 39 is provided diagonally on the surface of the frame 1 opposite to the product chute 37, and an overflow auxiliary burr chute 38 is provided on both sides of the lower die mounting board 13 for burr. By slanting the chute 39 so that it is lower, there is no need to manually take out the products and the residual products, and they can be collected separately in one process and sent to the next process as soon as the punching process is completed. Because of this, continuous processing is possible, there is no risk of eye contact, efficiency is improved, the accident rate is reduced, and it is very rational from the standpoint of safety and health as well as from the production cost perspective, and can be combined with other equipment. In some cases, it is an excellent invention for many industrial applications, such as being able to carry out a series of continuous processes including removal from molding, punching, and finished products.
