DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to, for example, a press working machine for providing an extruded working member with a connection such as a hole or a notch.

[0002]

2. Description of the Related Art For example, in order to make an extruded aluminum alloy material into a required fitting member, it is necessary to perform various kinds of connection processing such as holes and cutouts on the end of the material according to the design. It is well known that press working is performed in such processing. Conventionally, a multi-head press having a plurality of die sets provided with a predetermined mold is adopted, and a series of processing is sequentially performed by one operator.
Therefore, work efficiency is low and improvement of productivity by automation etc. is desired.

[0003] A die set used for press working generally has a structure in which a punch corresponding to the die set in a lower part is vertically movable.
Even when the die set is rotated and exchanged, the die set is installed horizontally at the position where the punch is driven. For this reason, in the press working, it is necessary to carry out the working while always keeping the work surface of the working member on the upper side.

For this reason, in a press machine for automatically performing press working, conventionally, a machine for rotating a work surface of a work member sequentially according to a pressing direction of each die set by a mechanism for rotating the work member, or a work metal. There is a type in which a pressing direction of a die set is changed so as to match a processing surface by providing a slide cam mechanism in a mold.

[0005] However, the cross-sectional shape of the processed member is usually not a simple rectangle but a complicated shape. In the case of a mechanism for rotating the processed member, the cross-sectional shape for gripping one end of such a processed member is generally used. Clamping and rotating devices are complicated and large, resulting in high costs.

Further, in the case where the working die is provided with the slide cam mechanism, the working member does not need to be rotated, but the working die itself becomes complicated, so that it tends to break down and the maintenance is not good. Also, at least a plurality of dies related to a series of processing are required, and using a die having such a slide cam mechanism increases costs.

[0007]

SUMMARY OF THE INVENTION It is an object of the present invention to provide an inexpensive manufacturing method which does not require a complicated mechanism for rotating the processing member itself or a die set in the processing of the connection of the processing member. It is an object of the present invention to provide a press machine which is excellent and can easily automate such a joining process.

[0008]

SUMMARY OF THE INVENTION A press working machine processes a work member having at least one work surface inclined with respect to a horizontal plane. The press unit includes one set of dies and a punch driving device thereof. The press unit is arranged so as to be inclined so that the press direction is orthogonal to one of the inclined work surfaces of the processing member sent to the press unit.

It is preferable to adopt the following configurations. At least two or more press units are arranged corresponding to the processing order of each processing surface in one processing member which is always sent from a certain direction in a certain posture.

There is provided a clamp for gripping the processing member in a fixed posture, and a reciprocating device for moving the clamp in a direction in which the processing member is fed into and pulled out of the press unit.

[0011] A pitch feeder is provided for moving the clamp in the direction in which the press units are arranged. A work member delivery device is provided for sending the work member released from the clamp in the clamp to the outside of the clamp.

[0012]

The structure in which the press unit is provided with one set of dies and its punch driving device enables the press work to be performed independently for each press unit. In the press unit, a punch driving device is driven, and press processing of a processing member is performed by a die set. The configuration in which the press unit is arranged so as to be inclined so that the pressing direction is orthogonal to one of the inclined work surfaces of the processing member sent to the press unit is such that the non-horizontal processing surface of the processing member is set to be horizontal. Thus, it is possible to perform the connection processing in a fixed posture on the processing member without rotating the processing member, and to omit a mechanism for rotating the processing member and a slide cam mechanism in the processing die.

[0013] The paper is always sent from a certain direction in a certain posture.
The configuration in which at least two or more press units are arranged in correspondence with the processing order of each processing surface in one processing member makes it possible to perform a connection processing without changing a feeding direction and a posture of the processing member. In addition, the positioning of the processing member in the processing die is facilitated. The clamp grips the workpiece in a fixed posture. The reciprocating device moves the clamp in the direction of feeding and pulling out the processing member with respect to the press unit, and constantly feeds or pulls out the processing member held by the clamp from the pressing unit in a certain direction from a certain direction. The pitch feeder makes it possible to move the clamps along the direction in which the press units are arranged, select the press units required for a series of connection processing, and sequentially move the processing members with respect to these. The processing member delivery device sends out the processing member released from the clamp in the clamp to the outside of the clamp.
