Abstract

PURPOSE:To reduce a discharging work, to improve a safety and to improve a working efficiency by dropping a formed part by the baffle plate arranged between a formed part taking-out position and its retreating position. CONSTITUTION:When a forging press forming stage is completed and an upper die reaches to an upper dead center by retreating upwards, an air cylinder 11 is driven to extend a piston rod 13, a formed part mounting base 8 is revolved with a revolving shaft 7 as the fulcrum and moved to a formed part taking-out position I. A worker takes out a formed part W from a forming lower die and mounts it on a mounting base 8, a blank is set on a forming lower die 3 which became empty, the mounting base 8 mounting the formed part W is revolved and faced for a retreating position II. At this time, the formed part W on the mounting base 8 is abutted to the baffle plate 17 arranged between the taking-out position I and retreating position II and dropped on the conveyor 10 for the forming article transfer. The conveyor 18 receives the formed part W and transfers it to the trimming press of the next stage.

Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to a discharge device that takes out a forged press-formed product from a mold and discharges it out of a press body.

1. Prior Art J The molded product that has completed the forging press forming process is supplied to the next process, such as a trimming press, by a conveyance device such as a conveyor.

Conventionally, a conveying device such as the conveyor is installed alongside a forging press machine, but due to the mechanism of the forging press machine, it has not been possible to install it continuously at the take-out position where the molded product is taken out from the mold. For this reason, in order to supply the forged press-formed product to the conveyance device, an operator uses metal chopsticks to take out the molded product from the mold and transfer it onto the conveyance device.

``Problems to be solved'' However, not only is the forged press-formed product heavy, but the detailed work requires the use of metal chopsticks at °C, so the workability is poor and the work is not necessarily easy for the worker. There wasn't. For this reason, there are problems that need to be solved, such as the need to improve workability and safety, thereby increasing work efficiency.

[Means to Solve the Problems] The present invention has been made to solve the above-mentioned problems, and the specific means thereof include the removal position at which the molded product is taken out from the forging press mold, and the position during the forging press forming process. A molded product mounting table that horizontally rotates and reciprocates between two positions and a retracted position, and a baffle plate that faces the top surface of the molded product mounting table midway between the two positions, and the baffle plate This is characterized in that the molded product is dropped from above the molded product III that moves through the lower surface of the molded product.

"Operation" The present invention has the above-mentioned specific means, and after the molded product is taken out from the mold and left on the molded product mounting table that has been horizontally rotated to the molded product take-out position, during the forging press forming process. When the molded product mounting table is moved horizontally to the retracted position, when the molded product mounting table passes the bottom surface of the baffle plate installed at the intermediate position, the molded product comes into contact with the baffle plate and falls from the molded product mounting table. .

"Example" Embodiments of the present invention will be described with reference to the accompanying drawings.

In FIG. 1, reference numeral 1 denotes a forging press body, and a forging press molding lower die 3 is fixed to the upper surface of a lower die bolster 2. 4
is a guide post of an upper type bolster (not shown).

Reference numeral 5 denotes a main body frame attached to the side surface of the lower bolster 2, which fixes a bearing 6 and supports a vertical pivot shaft 7.
support. 8 is a molded product II table which horizontally rotates and reciprocates between two positions, a forging press molded product take-out position (1) and a retreat position (II) during the forging press forming process, by means of a rotating shaft 7 #M. . Reference numeral 9 denotes an air cylinder mounting member installed on the main body frame 5 such that its position can be adjusted back and forth by rotation of the handle 10. The air cylinder 11, which is a turning drive source for the molded product mounting table 8, is pivotally mounted by a pin 12.

The tip of the piston rod 13 of the air cylinder 11 is connected to the connecting member 14 of the molded product mounting table 8 by a pin 15. Reference numeral 16 denotes a pair of fixing members erected from the main body frame 5, and a baffle plate 17 is fixed to the tips thereof. The baffle plate 17 is disposed midway between the take-out position opening → and the retracted position (II), and faces perpendicularly to the upper surface of the molded product mounting table 8.

18 is a conveyor for conveying molded products arranged below the baffle plate 17.

Additionally, Lsl is a limit switch that detects that the molded product mounting table 8 has pivoted to the retracted position.

"Operation of the embodiment" When the IJR press molding process is completed and the upper die retracts upward and reaches the top dead center, the air cylinder 11 is driven, the piston rod 13 is extended, and the molded product mounting table 8 is rotated about the pivot shaft 7 as a fulcrum and moved to the forging press molded product removal position rl(1). Then, the worker takes out the molded product W from the lower mold using metal chopsticks and molded product IX placement stand 8.
The worker takes out the molded product W and sets the material to be pressed onto the empty lower mold 3, and at the same time depresses the foot pedal switch to reverse drive the air cylinder 11 and press the piston. Contract the rod 13,
The molded product mounting table 8 on which the molded product W is placed is rotated and moved toward the retracted position ff(II) during the R press molding process.

At this time, the molded product W on the molded product 111yi white 8 comes into contact with the baffle plate 17 disposed between the take-out position (I) and the retracted position ([[), and the molded product I & falls from the placing table 8 onto the molded product conveyor 18. The molded product conveyor 18 receives the molded product W and transports it to the next process, the rimming press.

Said molded product a3! It is confirmed that the stand 8 has reached the retracted position (11) by activating the limit switch Ls1. The forging press process is not performed unless this limit switch Lsl is activated.

"Effect J" The present invention has the above-described specific means and effects, and after the forging press forming process is completed, a molded product mounting table is placed at the molded product take-out position between the molding upper mold and the lower mold that have retreated to the top dead center. When the molded product is mounted and moved to the retracted position during the forging press process, the molded product is dropped by a baffle plate placed between the molded product take-out position and the retracted position. The worker who took the molded product out of the lower mold
Since it is only necessary to place the molded product on the molded product mounting table that has been moved to the molded product take-out position, the work of discharging the molded product out of the press body is significantly reduced compared to the conventional method, and work efficiency is improved. This has the effect of improving safety and increasing work efficiency.
