Abstract

PURPOSE:To prevent seizure, etc. of a cylinder by constituting a titled device so that plural punch bodies receive a pressing force by aligning the center axis of its head with the center axis of the cylinder for driving the head, respectively. CONSTITUTION:A holder 5 can be moved in the right and left directions by a motor, an object to be worked 1 is provided along the right and left directions, and a desired punch body 3 among plural punch bodies 3 is positioned right under an impact cylinder 7 by moving the holder 5 to the right and left. In this state, when the impact cylinder 7 is driven, the center axis of a piston rod 15 of the impact cylinder is aligned with the center axis of a rod of the punch body 3, on the same straight line. Accordingly, the object to be worked 1 is punched without generating such moment as inclines the piston rod 15.

Description

[Detailed Description of the Invention] [Technical Field] The present invention provides a punch device, more specifically, a punch device comprising a plurality of types of punch bodies with different shapes of UL and lid, and one of the plurality of punch bodies is selected. The present invention relates to a punching device that punches workpieces into various shapes.

[Background technology]

Conventionally, as this type of punch device, one having the structure shown in FIG. 1 has been provided. With this device)
The kite tube (t41175→iE) is sunk behind the lid (2), and one syringe (41) is inserted into this kite tube (40).

The tip of 421 is inserted into the kite tube 14.
(It was structured so that there was a gap between II's 11 degrees and mouth/lid (421 points).
To select one of the lids (2), insert a sea urchin (4th floor) between its bottom and the tip of the lid (43) in the fried tube C4+11. through D... lid (4'lJ pressing force is 25 id cylinder 14

The structure was such that 1 was transferred and cut off. However, each O.
The upper end of the four lids is connected to a ram (441) that runs in the horizontal direction, and the four forces move at the same time. Therefore, the kite tube (4; the cylinder in the father-in-law (40

When C) is applied 4 times, a ram (44) VC'[1:-ment is generated around the center axis of the cylinder ttul'7'I due to the pressing force of the cylinder (40), and this is caused inside the cylinder (41). The piston (49 is tilted,
In order to solve this problem, we installed a ram (44
) to maintain balance with the 5-id 0-lid (40 may be provided, but the cylinder (41)) has a 1 mm (441 and 40) on both sides in the axial direction.
A special I door cylinder (4υ was required, which had the disadvantage of high cost. Also, a rod (4 cylinders and a JJ kite tube 0 was required between the ram (44) and the helid (21). Since the distance from the lid (2) to the cylinder (411) is large, there is a problem that the mounting becomes bulky.

[Purpose of the invention]

The present invention has been made in view of the above-mentioned problems, and its main purpose is to move the punch body of the number of punches to the central axis and the lid, respectively. By aligning the center axis of the cylinder with the center axis of the cylinder and receiving the pressing force from the cylinder, the cylinder head is driven so that the histones do not tilt to the left or right, preventing the cylinder from seizing. It's about putting it out.

[Disclosure of the invention]

In the present invention, a plurality of punch bodies are installed movably with respect to the striking cylinder JjVc, and the bunch wood is moved to align the center axis of the striking cylinder and the head of one punch body. Align with the center axis.

A hole lid (2) is placed on the lower piece (25) of the hole 1j (61), and a tie (4) is provided at the lower part 1a facing B. The first workpiece (1), such as an L-shaped antile material or a flat plate material, is sandwiched between the lid (21 and the soi (4)) to generate punching force. . There is a tie fixing F4J screw @ in front of the tie (4).
Push the part to be punched out between the upper piece I211 and the lower piece of the bolt (5) and position it on the tie (4), and then cut off the impact cylinder (7). When the firing head (6) is pushed down, the workpiece (1) is pressed between the first slot (2) and the tie (4) and punched into a desired square shape. At this time, the workpiece (1) is held by a tweeter and is successively rolled in its longitudinal direction to be punched out next. Holder (5) is ℃-ta (8)
Since it can be machined horizontally and moved horizontally, the workpiece

The center axis and the center 1111 of the 01 lid (9) of the punch body (3) align on the same straight line, and the workpiece can be machined without generating a moment that would tilt the piston 〇/lid (16). It is possible to punch out the object f1+. In addition, since the base (121) is movable back and forth by the 7-9081, it is possible to punch out pieces in different directions from the inside of the workpiece ill, which is sent by the tweeter so as to run left and right as shown in Figure 9. It can be done.
