Description

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 forming an opening, a cutout or the like in an extruded member.

[0002]

2. Description of the Related Art For example, in order to finish an extruded aluminum alloy profile into a required fitting member, it is necessary to make various joints such as holes and notches at the end of the profile according to the design. It is well known that press working is performed in those workings. Then, conventionally, a multi-head press machine in which a plurality of sets of die sets each having a predetermined die is installed side by side 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.

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

For this reason, in a press working machine for automatically carrying out press working, conventionally, a mechanism for rotating the working member is used to sequentially rotate the working surface of the working member in accordance with the pressing direction of each die set and the working metal. There is a type in which a slide cam mechanism is provided in the die to change the pressing direction of the die set so as to match the processing surface.

However, the cross-sectional shape of the machined member is usually not a simple rectangle but a complicated shape, and in a mechanism for rotating the machined member, one end portion of the machined member is grasped. The clamp and the rotating device are complicated and large, and the cost is high.

Further, in the case where the processing die is provided with the slide cam mechanism, it is not necessary to rotate the processing member, but since the processing die itself becomes complicated, it easily breaks down and the maintainability is not good. In addition, at least a plurality of dies required for a series of processes are required, and the cost is high if a die provided with such a slide cam mechanism is used.

[0007]

SUMMARY OF THE INVENTION An object of the present invention is to manufacture a processed member at a low cost without rotating the processed member itself or requiring a complicated mechanism for a die set, and can be manufactured at a low cost and maintainable. An object of the present invention is to provide a press working machine that is excellent and that can easily automate such finishing.

[0008]

The press unit includes a set of dies and a punch driving device for the dies. 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 employ the following configurations. At least two or more press units are arranged in correspondence with the processing order of each surface to be processed in one processing member that is always fed from a certain direction in a certain posture.

In the press working machine of the present invention, the press unit is provided with a set of dies and a punch driving device for the die set, and this press unit sends the press direction to the press unit. Since it is arranged so as to be orthogonal to one of the above, the processing member is pressed in a certain posture without rotating the processing member itself so that the non-horizontal surface of the processing member becomes horizontal. It is only necessary to send it to the machine, and when the joint processing of the processed member is performed manually, the work becomes easy and the automation becomes easy.

Since a mechanism for rotating the processed member and a complicated mechanism for the die set are not required, the manufacturing can be carried out at low cost and the maintainability is excellent.

By arranging a plurality of press units so as to be orthogonal to each of the surfaces to be machined in accordance with the processing order of the surfaces to be machined in one machined member, the machined members are always kept in a certain posture from a certain direction.

By providing the processing member held by the clamp to the press unit from a certain direction in a constant posture at all times and then pulling it out, the clamp is moved along the arranging direction of the press unit to make a series of joints. It becomes possible to select the press units necessary for processing and move the processing members sequentially with respect to these, and it is only necessary to perform the work process of holding the processing members in the clamps on the processing line, which enables labor saving. Become.

By providing the processing member feeding device for sending the processing member whose grip is released in the clamp to the outside of the clamp, it is possible to save the labor for removing the processing member from the clamp.

When a plurality of press workings are performed on one working member, a die set corresponding to each process is prepared, and the die set corresponding to the inclined work surface of the working member is the pressing direction of the die set. Are arranged so as to be orthogonal to the inclined surface to be processed, and by processing the processing members in the same posture for each die set,
There is no need to change the posture of the processing member for each die set, and by simply sending the processing member from a certain direction in a certain posture at all times, it is possible to successively perform the finishing process of each process. Compared to those requiring a rotating mechanism and rotational position control means for rotationally moving and positioning, the reciprocating movement control means for making linear movement in the feeding and drawing directions of the processing member with respect to the press unit, and the arrangement direction of the press units. Since it suffices to provide a pitch feed control means for linearly moving the processing member along it, automation becomes easy.
