Description

[Detailed Description of the Invention] This invention relates to a press-formed product take-out device that is capable of separating and taking out a molded product formed by a press and scraps generated due to molding.

Conventionally, molded products formed using a press are discharged using an extrusion device operated by an air cylinder, etc., but with this method, if scraps are generated during molding, the molded product and scrap are discharged at the same time. This requires work to separate the parts, resulting in very poor work efficiency.

This invention was made with the aim of improving this problem, and provides a press-formed product take-out device that separates the press-formed product from the scrap and takes it out in one step. This eliminates the need for separation work after removal.

This invention will be described in detail below with reference to an illustrated embodiment.

In the figure, 1 is a press body, on which a lower die 3 is fixed on a bolster 2.

An upper mold 5 that is attached to a slide 4 and moves up and down is provided above the lower mold 3, and between the upper mold 5 and the lower mold 3, the molded product A is
The molding is done.

Reference numeral 7 denotes a main body of this apparatus, which is installed at the rear of the press main body 1 and has a guide rail 9 laid on a pedestal 8.

The guide rail 9 is provided with a large number of rollers 10 at its bottom, and guides the movement of the slider 11 inserted between these rollers 10 and the guide rail 9.
1 is moved forward and backward toward the press body 1 by a drive cylinder 12 such as an air cylinder.

The drive cylinder 12 is located below the guide rail 9 and installed on the pedestal 8, and a sprocket 13 is rotatably supported at the tip of a piston rod 12H protruding toward the press body 1 side.

The middle part of a chain 14 whose one end is tied to the frame 8 is wound around the sprocket 13, and the other end of the chain 14 is wound around a bracket 15 which is protruded from the bottom of the slider 11.
It is tied to

Furthermore, a tension spring 18 is stretched between a bracket 16 projecting from the top of the slider 11 and a bracket 17 projecting from the rear end of the guide rail 9 to bias the slider 11 in the backward direction at all times. At the same time, the proximal end of a take-out arm 19 is pivotally attached to the distal end of the slider 11 by a pin 20.

The take-out arm 19 is pivotally attached to the slider 11 so that its distal end can rotate only upward from the same horizontal position as the slider 11, and a pair of claw bodies 21 are provided at the distal end spaced apart in the width direction. There is.

Each claw body 21 is pivotally mounted within a recessed part 19a formed at the distal end of the take-out arm 19, with the distal end facing downward.
At the rear, a stopper 22 is provided to protrude from the tip of the take-out arm 19, and the tip of the claw body 21 is moved from the downward position to the recessed portion 19.
a It is rotatable only inward.

Further, a scrap ejecting lever 23 is provided on the upper surface of the distal end side of the ejecting arm 19.

This scrap ejection lever 23 is pivoted on the proximal side or one side of the take-out arm 19, and a helical spring 23 provided on the pivot portion
The tip side is biased toward the claw body 21 side by H, and
A guide 25 is provided on the upper surface of the take-out arm 19 in an arcuate manner and projects along the locus of rotation of the tip of the scrap discharge lever 23.

Further, the proximal end of the scrap ejection lever 23 is connected to the take-out arm 19.
The scrap discharging lever 23 protrudes laterally and engages with the stopper pin 26 only when the take-out arm 19 retreats, so that the tip of the scrap ejection lever 23 is rotated along the guide 25.

On the other hand, 27 is a cam stopper that is attached to the slide 11 and moves up and down, and can come into contact with a stopper roll 28 provided on the side of the tip of the take-out arm 19, and when the slide 11 is lowered to the bottom dead center. Sometimes, the cam surface 27 a
The stopper roll 28 is brought into contact with the stopper roll 28 to prevent the take-out arm 19 from entering between the upper and lower molds 5 and 3 and being damaged during molding.

Note that 29 is a chute for collecting the molded product A provided below the take-out arm 19, and 30 is a chute for collecting scraps provided on the same side.

However, the upper mold 5 and lower mold 3 descended together with the slider 11.
When the molding of the molded product A is completed between and the upper die 5 is raised,
The drive cylinder 12 is extended by a command from a press rotary cam (not shown), and the chain 14 causes the drive cylinder 1 to extend.
The slider 11 is advanced toward the press body 1 at about twice the speed at which the slider 2 is extended.

As a result, the take-out arm 1 provided at the tip of the slider 11
9 is inserted between the upper die 5 and the lower die 3, and the claw body 21 at the tip of the take-out arm 19 is recessed into the recess 19a when passing over the molded product A, and is placed on the opposite side of the molded product A. It reaches to the top and stands up again on the other side due to its own weight.

Next, in this state, the scrap a attached to the upper die 5 is taken out from the upper die 5 using a knockout pin (not shown) and dropped into the guide 25 on the arm 19, and the drive cylinder 12 is shortened and the slider 11 is moved by the tension spring 18. make them retreat.

Claw body 2 engaged with molded product A as slider 11 retreats
1, the molded product A is taken out from above the lower mold 3 and dropped into the molded product recovery chute 29, and when the base end of the scrap ejection lever comes into contact with the stopper pin 26, the "scraffing" event [the output lever 23 The scrap a on the take-out arm 19 is discharged to the side of the take-out arm 19, and is dropped into the scrap collection chute 30, where the molded product A is
and are collected in a separated state into a product and scrap collection container (not shown).

As described in detail above, this invention allows the molded product to be discharged from the take-out arm that moves forward after molding, and the scraps to be discharged in a separated state by the scrap discharge lever provided on the take-out arm. By collecting these molded products and scraps using a separate collection chute, it is not necessary to separate the scraps from the molded products after collection, and the work efficiency is significantly improved.
