Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a turnover device for a transfer press.

A kel turnover device in a transfer press is a device that generally rotates a surface-treated workpiece by 90 degrees or 180 degrees between molds when surface-processing the workpiece in the next step.

The present invention automatically performs the turnover by interlocking the turnover device with the operation of the feeder of the transfer press.

First, an example of the movement diagram of the feeder of the transfer press is shown in Fig. 1.2. Figure 1 shows three-dimensional feed,
The figure shows an example of two-dimensional feeding. In FIG. 1, in mold No. 0, the position of the front feeder is A1, and the position of the rear feeder is A'. First, the feeders of A, A' move forward in opposition and clamp the workpiece until they reach positions B, B'. At positions B and B', the feedper is raised by a predetermined dimension, and then at positions c and
At c', it moves toward the next mold No. n + 1.

During this movement, the front and rear fins rotate 1800 times.

Beams in the diagram.

The known 6-way turnover device, shown as D', turns most of the distance DE, D'E' until reaching the next n+1 mold position E, E'. It also varies depending on the distance between the molds and the distance between the molds. The descent starts from position E, E' and reaches the end point of descent at position F, F', where the workpiece is n +
It is passed to the clamp of the first mold. Position F.

At F', the parallel movement of the front and rear feeders ends, and the feeders move away from the workpiece in an unclamped state to position G.
, reaches G'. From position G, G' to position A.

Return to A' and wait for the next cycle.

FIG. 2 shows a feed per movement diagram due to two-dimensional feeding, in which movement is performed without vertical movement between BC and EF in FIG. Therefore, the symbols corresponding to each stop position are the same as those in FIG. 1, and will be briefly described. The feeder in the nth mold waits at position A I A', and at a predetermined time it returns to position c.
, move forward toward c' and clamp the workpiece. Grip the workpiece and move it toward the n+1 mold, during which time it is reversed 180 degrees at D and D', and stops at positions E and E' when it reaches the n+1 mold, and the workpiece is moved. Pass and position G relatively apart.

Reach G/. From position G, G' to standby position A,
Return to A'.

The above-mentioned movement of the feeder and reversal between molds are known, but in the past, they were designed and manufactured individually and no consideration was given to versatility, making it extremely difficult to repurpose existing equipment, and creating a new one. It is expensive to design and manufacture.

An object of the present invention is to provide a turnover IT for a transfer press that is a unit incorporating a device for rotating a shaft on which a workpiece holding finger is attached.

To achieve the above-mentioned object, the turnover device according to the present invention comprises a main body which is removably attached to a feedper, a shaft which is rotatably supported on the main body and to which a workpiece holding finger is removably attached, and a turnover device which is attached to the shaft. It includes a fixed pinion and a rack that engages the pinion and is slidably supported on the body.

With the above-mentioned configuration, the device for rotating the finger attachment shaft is incorporated into the turnover device as a rack and a binion, making it extremely compact and easy to install. In order to reverse the fingers, it is sufficient to place the rack at a stop and move the device, which can be accomplished by a very simple stop.

Therefore, there is no need to separately design and manufacture functional parts for turnover, and it can be used in combination with any transfer device. In this case, the distance between the molds and the size of the workpiece are irrelevant, and there is a wide range of compatibility.

Embodiments and drawings illustrating the present invention will be described.

As shown in FIGS. 3a and 3b, a Luster blade is installed, and the rack moves 1! with the movement of the feeder, which will be described later. ! Control. On the upper ram of the polster blade, there are multiple upper molds A at positions corresponding to the plurality of lower molds A, B, and C.
B and C are arranged.

Between the upper molds A, B, and C and the lower molds A, B, and C, feeders that move in a predetermined manner are arranged in corresponding states.5). The feed bar base mounts in place a body that supports rotatable fingers and a slidable rack.
