Abstract

PURPOSE:To simplify the structure of a metallic die, and to improve the maintenance property by constituting a titled device so that plural press works by a feed of once and its inversion fetching can be executed simultaneously, and each metallic die is made independent of each other. CONSTITUTION:A titled device has one piece of shaft 1 which slides horizontally in order to feed an object to be worked by a prescribed distance, on the end or a supply part side of the object to be worked, and has a groove 3a of suitable width conforming with the size and shape of the object to be worked, on the upper face. Also, this device is provided with one piece of rail 3 having one piece of pin 5 attached horizontally in order to invert the object to be worked by 180 deg., when fetching the object to be worked, on the end face of a fetching part side of the object to be worked. On the upper part and the lower part of this rail 3, one set of die set 6 having plural consecutive metallic dies 2a, 2b attached continuously in parallel to the rail 3 is provided. Also, this device is provided with a chute 4 whose section has been formed to U-shape, for feeding the object to be worked to the next process, and a revolving eccentric shaft 7 for operating the die set 6.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a press apparatus that performs a plurality of press operations such as cutting, bending, and drilling.

Configuration of conventional examples and their problems In conventional press jigs of this type, press processing in the numerical process is often performed using a single die, and the structures of the dies and press jigs are multiple. This makes adjustment and maintenance of the mold considerably difficult, and also reduces safety, cost, maintenance, and
There were many problems in terms of workability, etc. In addition, when multiple steps of press processing are required, an automatic transfer press may be used, but this not only requires a large initial investment but also requires large equipment.

OBJECTS OF THE INVENTION The present invention aims to eliminate such conventional drawbacks, simplify the mold structure, improve maintainability, and improve functionality.

Structure of the Invention In order to achieve all of these objects, the present invention provides a horizontally sliding OT for feeding the workpiece a certain distance to the end face of the supply section of the workpiece.
It has a single shaft that can handle the workpiece, has a groove on the upper surface with an appropriate width that matches the size and shape of the workpiece, and has a groove on the side end surface of the workpiece take-out part that allows the workpiece to be removed when the workpiece is taken out. A rail with a horizontally mounted pin for reversing the degree of rotation, and a series of molds disposed above and below the rail and successively dammed in parallel with the rail. The die set is composed of a die set having a die center and a rotating eccentric shaft for operating the die center.

DESCRIPTION OF EMBODIMENTS As shown in FIGS. 1 and 2, there is one shaft 1 that slides horizontally on the end surface of the supply section of the workpiece for feeding the workpiece a certain distance, and the upper surface has a groove 3a of an appropriate width that matches the size and shape of the workpiece, and a workpiece take-out part g41.
A single rail 3 is provided on the end face of 1' and is mounted horizontally and has a single pin 6 for inverting the workpiece by 180 degrees when taking out the workpiece. A die set 6 having a plurality of series of molds 2a and 2bi is attached to the upper and lower parts of the rail 3 in parallel with the rail 3.
is provided. Further, a chute 4 having a U-shaped cross section for sending the workpiece to the next process, and a rotating eccentric shaft 7 for making one die set 6 are provided. The operation of this device is as shown in FIGS. 3A to 3C, by placing the workpiece 8 on the feed section of the rail 3 and pushing the shaft 1 a certain distance, the workpiece 8 is placed on the groove 3a of the rail 3. The workpiece 8 is fed and pressed by the first molds 2a and 2b, and the next workpiece 8 is fed and conveyed in the same manner as described above. The workpiece 8 supplied first is the second mold 2a.

2b is pressed. This kind of work is repeated: After the workpieces 8 are sequentially conveyed on the groove 3a of the rail 3 and pressed one after another, the workpieces 8td, 8td, The workpiece 8 is placed on the pin 5 attached to the take-out part of the rail 3, and the workpiece 8 is turned over by the pin and falls onto the chute 4 as shown in FIG. 3C, and is sent to the next process. go.

By repeating the above operations using a simple press jig with such a configuration, multiple presses can be performed simultaneously with just one feed operation, and the workpiece that has been press-processed can be It is sent to the position of the mold for the next press work, and can be taken out while being turned over, making it possible to perform very efficient press work.

In particular, as shown in Figure 3, when a part of the workpiece 8 (for example, a terminal) is bent, if it is dropped into the chute 4 as it is, the bent part will hit the chute and break. Although there are problems such as poor bending dimension accuracy, it is very effective because the workpiece 8 is reversed using the pin 6 attached to the workpiece take-out part of the rail 3, which prevents damage to the bent part. .

Effects of the Invention As described above, according to the present invention, it is possible to simultaneously carry out multiple pressing operations and reversal and ejection by -times of feeding, and also because each mold is independent of each other, making it possible to repair, replace, or change the mold. It is very easy to clean, etc., and it is also easy to handle, such as cleaning. □
