Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a device for positioning a flanged metal to a press when finishing the flanged metal using a press.

(Prior Art) There is an operation in which a fan-shaped piece A is removed at an angle of about 20 degrees from both ends of both flanges 101 and 102 of a flanged metal 100 toward the outer periphery, as shown in FIG.
Such conventional work was done with cutting machines.

(Problem to be solved by the invention) In order to improve efficiency compared to cutting work, punch cutting using a press is considered, but in order to cut both flanges 101 and 102 in the same way, it is necessary to cut both flanges 101 and 102 in the same way. In order to reverse the parts 101 and 102 and fix them to the die again, it was necessary to develop an efficient and reliable positioning device for the press.

(Means for Solving the Problems) The present invention has been made in view of the above circumstances, and its configuration is as follows.

In a device for positioning a flanged metal on a die holder of a press with a die inserted between both flanges, a guide groove is formed at both ends of the punch holder with an upward slope toward the end face of the flanged metal. A guide plate is provided vertically, both ends are guided by the guide groove, and a stopper holder is provided in the middle part having a stopper that can be biased toward the end surface of the flanged metal by a spring. This is a positioning device for a flanged metal in a press, which is provided with a cradle for a stopper holder held in a position facing the flanged metal, and a cam plate having a jaw portion that prevents the stopper holder from rising.

(Function) When the punch holder is lowered, the stopper holder whose both ends are guided by the guide grooves of the guide plate vertically provided at both ends of the punch holder is lowered together with the guide plate. The stopper is attached to the stopper holder and can be biased by a spring toward the end face of the flanged metal placed on the die holder of the press with the die inserted between the flanges.
When the stopper holder comes to the position facing the flanged metal, it is prevented from descending by both holders and guided along the upward slope guide groove toward the end face of the flanged metal, and the stopper holder is stopped by both holders. The table moves forward toward the end of the flanged metal, enters the underside of the jaw of the cam plate, and the stopper comes into contact with the end of the flanged metal, compressing the spring and pressing the flanged metal against the die to position it. do. If you raise the punch holder after finishing the flat and flanged metal,
Since the stopper holder is prevented from rising by the jaws of the cam plate, it is guided by the guide grooves of the guide plate and moves away from the flanged metal on both holders, detaching from the lower surface of the jaws of the cam plate,
It rises together with the cam plate and returns to its original position.

(Embodiment) An embodiment of the apparatus for positioning a flanged metal to a press according to the present invention will be described based on FIGS. 1 to 4. In this embodiment, both flanges 10 of the flanged metal 100 are
The operation of cutting and removing the fan-shaped pieces A at both ends of the pipe No. 1, 102 will be explained as an example.

In FIG. 1, 1 is a semicircular die, 2 is a die holder, 3 is an arcuate part, 4 is a punch holder, and 5 are attached to both ends of the punch holder 4, and the ends of the flange 101 or 102. A pair of punches for cutting the fan-shaped piece A from the section.

That is, the die 1 fixed on the die holder 2 is inserted between the flanges 101 and 102 of the flanged metal, and the punch holder 4 is lowered by being guided by a guide post (not shown).
is pressed against the die 1, and the fan-shaped pieces A at both ends are cut using both punches 5, 5. The present invention is a device that presses both end surfaces of the flanged metal 100 to ensure alignment with the die 1 and eliminate circumferential runout for the above-mentioned work.

Each numeral 6 is a guide plate that is vertically disposed at both ends of the punch holder 4 and positioned in front of the end face of the die 1, and is provided with a guide groove 6a having an upward slope toward the die 1 side. Reference numeral 7 denotes a stopper holder, both ends of which are guided by guide grooves 6a, 6a, respectively. 8 is a stopper that is provided in the middle part of the stopper holder 7 in parallel to the end surface of the die 1, has a length that spans both end surfaces of the flanged metal 100, and has a height lower than the width of the metal 100. . As shown in FIG. 4, the push rod 9 has its large-diameter tail end 9a engaged with one surface of a partition wall 7a provided in the middle of the through hole of the stopper holder 7, and its tip end is connected to the partition wall 7a. 7a and is fixed to the stopper 8. A coil spring 10 is interposed on the outer periphery of the push rod 9 between the other surface of the partition wall 7a and the stopper 8 to urge it toward the end surface of the flanged metal 100.

Each 11 is a pedestal, the height of which is the height of the flange metal 10 attached to the die 1 at the flange parts 101 and 102.
It is set equal to the lower edge of 0. Each cam plate 12 is provided on the flange metal 100 side of the stopper holder 7 on the inside of both guide plates 6, 6, and can lock the upper surface of the stopper holder 7 with a jaw portion 12a.

Next, the effect will be explained.

As shown in FIG. 2, if the punch holder 4 is lowered with both ends of the stopper holder 7 supported by the lower edge of the guide groove 6a of the guide plate,
The stopper holder 7 descends together with both guide plates 6 and comes into contact with both receivers 11, 11. Further, when the punch holder 4 is lowered, the stopper holder 7 is guided by the guide groove 6a so as to be close to both ends of the flanged metal 100, and the stopper holder 7 is guided by the guide groove 6a so as to be close to both ends of the flanged metal 100.
1 and 11 and enters below the jaw part 12a of the cam plate as shown in FIG. Press the surface.
Then, the pad 3 and punch 5 are operated to cut the fan-shaped pieces A at both ends of the flanged metal 100.

Next, when the punch holder 4 is raised, as both the guide plates 6, 6 rise, the stopper holder 7 follows the rise by the jaw part 12 of the cam plate.
a, and the guide grooves 6a of both guide plates,
6a, moves on both holders 11, 11 away from both end surfaces of the flanged metal 100, reaches the lower edge of both guide grooves 6a, 6a, and separates from the lower surface of the jaw portion 12a of the cam plate. Then, as the punch holder 4 further rises, it returns to the original position shown in FIG.

(Effect of the invention) As can be understood from the above explanation, according to the positioning device for the flanged metal in the press according to the present invention, the end face of the flanged metal is pressed against the die, so that the flanged metal is It is possible to accurately position the die with respect to the die without centering error or runout in the circumferential direction, and since the operation of this device is linked to the operation of the punch holder, that is, the operation of the punch, it can be operated quickly and reliably.
