Abstract

PURPOSE:To obtain a drawing device capable of performing its drawing with high efficiency and high reduction by moving alternately a die box for drawing and a chucking box for catching a drawing material on the same sliding shafts. CONSTITUTION:Die box 13 which houses a drawing die and is used for drawing is installed movably on sliding shafts 53 through a driving device 15; and a drawing material 2 is inserted in said die hole after providing a pointing to the tip of material 2 and then is caught by a chucking device housed in a chucking box 7 installed slidably on the shafts 53. Next, the die box 13 is moved to the front side with respect to the drawing direction to perform the drawing by using the die. Next, the chucking box 7 is advanced after unfastening the chuck to catch the drawn material 2 thereby drawing the material by repeating said operations.

Description

[Detailed description of the invention] The present invention relates to a drawing device.

Conventionally, in a drawing device using a die, the die is fixed to the drawing device, and the chuck performs the drawing process by chucking the drawn material processed according to the diameter of the die hole.

In a conventional drawing device using a die, the die is fixed to a die holder in which the die is set, and is housed in a die box containing a built-in device for supplying lubricant and the like. After applying the tip of the drawn material to be processed, the workpiece inserted through the die hole is chucked.
After they are securely engaged, a pulling force is applied to the chuck in the pulling direction to perform the drawing process. At this time, when winding up the workpiece onto a drum, the tip of the workpiece is fixed to the drum and the workpiece is wound up.

Even in this case, the distance between the dice box and the drum remains constant. In the case of drawing using a draw bench instead of the winding method, the tip of the workpiece is chucked and entangled with a chain moving in the drawing direction, and drawing is performed. In all of these, the die box is in a fixed position and does not move back and forth in the drawing direction.

The present invention is fundamentally different from such conventional extraction devices.

The apparatus of the present invention will be explained in detail. FIGS. 1 and 2 are diagrams of a conventional drawing device, and FIGS. FIG. 1 shows a conventional winding drum type drawing device, in which 11 is a die box, 21 is a drawn material, and 61 is a winding drum. In this drawing device, the 11 dice boxes are fixed without moving, and the distance from the drum 61 is constant.

What is shown in Fig. 2 is a conventional draw bench type drawing device, in which 12 is a die box, the tip 21 of the drawn material 2 is gripped by the chuck claw 41, and it is held on the rail 51. Connect the top to 52 sliding platforms,
This is a device that performs drawing processing by pulling with a wire.

The dice box 12 in this case is also not fixed and movable.

In conventional drawing equipment such as this, one die box has
It is a winding drum or a chuck device, not a device that stacks them and pulls them out.

That is, when drawing one piece of workpiece with a die, there is a winding drum after the die box, and the drawn workpiece is once wound up on the winding drum and then applied to the next die.

Or instead of a winding drum, wind it around a capstan.
Either the structure is such that the die is placed on the next die, or the structure is such that the die is pulled out from one die box and pulled with a rope, like a draw bench, and there is a chuck after the die so that the die can be moved back and forth. There is no structure in which the chuck moves and the chuck is linked to it. What is shown in FIG. 6 and subsequent figures is a shape diagram of an embodiment according to the present invention. FIG. 6 is a top view of the device according to the present invention, FIG. 4 is a perspective view of FIG. 6, and FIG. 5 is a die and chuck device installed inside the die box and chuck box. .

16 is a dice box in which 14 dice are installed. The 16 die boxes have 15 drivable devices and are movable on 55 slide rails. Reference numeral 2 denotes a drawn material, and the tip of the material 22 inserted through the hole diameter of the die 14 is strongly pressed by the catch portion 71 of the chuck device. The catch surface 71 may be in the form of a roll, and the force for pressing the catch surface of the machete 71 against the surface of the drawn material may be a hydraulic cylinder 72 or a mechanical structure. The chuck box in which such a catch device is installed also has a seven-wheel drive device, which allows two of the 55 rails to be freely moved. To describe an example of the operation of the drawing device shown in Figs. 6, 4, and 5, the tip of the workpiece No. 2 is tipped, and the hole diameter of the No. 14 die is inserted. Then catch the 26 drawn material with the chuck box 7, and then transfer it to the die box 16 (d
Shifts toward the front with respect to the pulling direction.

In other words, it is possible to obtain a workpiece that is drawn out with a die by the amount transferred. Later, release the catch 71 in the chuck box and remove the catch, and move the chuck box 7 until it touches the back of the dice box.
Shorten the distance between the dice box and chuck box. At that position, the chuck box catches the drawn material, and then the die box moves forward to sequentially perform the drawing process.

What is shown in FIG. 6 is a shape diagram in which a plurality of die boxes and chuck boxes are used to process a linear drawn material.

The structure is such that a plurality of dice boxes of 16.16' and a plurality of chuck boxes of 7.7' can be operated as a pair of 1 rotor, 7.16' and 7'.

The present invention is a drawing device in which the die box moves and the chuck box also moves accordingly, and is capable of achieving various effects such as high reduction.
