Description

  The present invention relates to a sponge titanium cutting machine, and more particularly to a structure for adjusting a contact plate thereof.

  Conventionally, for example, it is known that pure titanium tetrachloride reacts with metallic magnesium heated to about 900 ° C. in a stainless steel container, and titanium tetrachloride is reduced by the reducing action of magnesium to obtain sponge titanium. . After the reduction separation, the sponge titanium is cut by a press-cut type crushing equipment (sponge titanium cutting machine), and then cut by a cutting machine and a crusher.

  For example, in a sponge titanium cutting machine such as Patent Document 1, a sponge titanium sandwiched between a moving blade provided on a slide that moves up and down and a fixed blade provided on an end point of a chute is applied to a contact plate provided on the slide. It is cut by the thickness of the distance between the contact surface and the moving blade.

  However, in the configuration as in Patent Document 1, as shown in FIG. 8 (a), the position of the contact surface 120a for adjusting the amount of entry of sponge titanium is the position of the adjusting member 121 such as a shim shown in FIG. 8 (b). This is done by changing the number and thickness. Therefore, at the time of adjustment, it is necessary to loosen all the numerous bolts 133 that fix the contact plate 120 once and remove the contact plate 120 and change the number and thickness of the adjustment members 121. The equipment had to be dismantled and it took a lot of time and was a day job. In addition, normally, shims having a predetermined thickness of 6 mm, 9 mm,... Are prepared, but there is a problem that fine adjustment while checking the shape of the sponge titanium after cutting has a limit.

  This invention is made | formed in view of this point, The place made into the objective is to enable it to adjust the position of a contact surface easily in a sponge titanium cutting device.

  In order to achieve the above object, the present invention makes it possible to change the position of the contact surface of the contact plate that regulates the amount of sponge titanium entering by the wedge structure.

Specifically, the titanium sponge cutting device of the first invention is
An inlet for sponge titanium,
A moving blade that is fixed to the slide that moves up and down and cuts the sponge titanium that has been introduced from the insertion port,

The contact plate, the contact surface adjusting portion, and the mounting base are configured to be integrally removable along the sliding key .

According to the above configuration, since the position of the contact surface of the contact plate can be moved and finely adjusted using the wedge structure, there is no need to adjust by sandwiching the adjustment member as in the prior art. Further, since the pair of movable wedges are displaced while sliding the inclined surfaces, the contact plate is stably held by the pair of movable wedges without excessively increasing the movable wedge. Thus, fine adjustment of the position of the contact surface can be performed. Furthermore, since the contact plate, the mounting base, and the contact surface adjusting portion can be removed integrally along the sliding key, the maintenance work is very easy.

As described above, according to the present invention, since the position of the contact surface of the contact plate can be finely adjusted using the wedge structure, the position of the contact surface can be adjusted by sandwiching the adjustment member as in the prior art. Therefore, the adjustment work can be performed very easily and the maintenance work can be performed very easily .

It is the arrow view seen from the VII direction of FIG. (A) shows the adjustment part of the moving blade which concerns on a prior art, and its periphery, (b) is a front view which shows a shim.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 2 shows a sponge titanium cutting machine 1 as a slide drive device according to an embodiment of the present invention. The sponge titanium cutting machine 1 includes a crank chamber 2 and a leg portion 3 that supports the crank chamber 2. Both ends of the main shaft 5 are supported by the pair of side frames 4 constituting the crank chamber 2 so as not to rotate. As shown in FIG. 3, an eccentric member 6 is fitted on the main shaft 5 and is rotated by an electric motor 7 as a drive source.

  Specifically, the electric motor 7 is placed above the crank chamber 2, and the rotating shaft 7 a is belt-coupled to, for example, a flywheel 8 that is rotatably supported above the crank chamber 2. As shown in FIG. 3, the small gear 8 a that is integrally rotated with the flywheel 8 is engaged with the large gear 6 a that is integrally rotated with the eccentric member 6. Thereby, the eccentric member 6 is rotationally driven.

  As shown in FIG. 4, one end side of the connecting rod 10 is fitted on the eccentric portion 6 b of the eccentric member 6. The other end of the connecting rod 10 is connected to the plunger 11 by a pin 10a. Since the plunger 11 is guided by the plunger guide 11 a, the swinging motion of the eccentric portion 6 b is converted into the lifting motion of the plunger 11. The up-and-down movement direction X defined by the direction in which the plunger guide 11a extends is inclined with respect to the ground. A slide 12 is connected to the lower end of the plunger 11, and the slide 12 can be moved up and down in the hollow slide housing portion 12 a along the up-and-down movement direction X.

As shown in FIG. 5, the fixed blade 13 is fixed to the fixed blade base 38 below the slide housing portion 12 a , and the movable blade 14 is fixed to the slide 12 so as to correspond to the fixed blade 13. . A supply path 15 having an inclined passage for supplying sponge titanium W is connected to the fixed blade mount 38 , and the sponge titanium W is sequentially supplied from an insertion port 15a formed above the fixed blade 13. ing.

  As shown in FIGS. 1 and 7, the slide 12 is provided with a contact plate 20 that regulates the amount L of the sponge titanium W when the moving blade 14 is raised below the moving blade 14. The abutting plate 20 closes the insertion port 15a from the back side, and is fixed to the block-shaped mounting base 30 by mounting bolts 31 from the back side. Since this mounting bolt 31 is not visible from the front of the abutting plate 20, it is less likely to be damaged than a bolt head appearing on the surface side as shown in FIG. The mount 30 is movable along a sliding key 32 (shown only in FIG. 7) extending in the Y direction perpendicular to the up-and-down movement direction X.

  On the back side of the contact plate 20, a contact surface adjusting portion 21 is provided that finely adjusts the position of the contact surface 20 a of the contact plate 20 by moving the position of the contact surface 20 with a wedge structure. Specifically, the contact surface adjusting portion 21 includes a pair of movable wedges 22 and 23 that are arranged to face each other so that the inclined surfaces 22a and 23a are in sliding contact with each other. Each of the movable wedges 22 and 23 is, for example, a right triangle plate having a cross-section cut off, and just a pair of movable wedges 22 and 23 divides one steel plate at the inclined surfaces 22a and 23a. It has become a shape. By displacing the pair of movable wedges 22 and 23 while the inclined surfaces 22a and 23a are in sliding contact with each other, the contact plate 20 is slid so that the position of the contact surface 20a is perpendicular to the vertical movement direction X. Fine adjustment is possible in the direction.

  The pair of movable wedges 22 and 23 are sandwiched by, for example, four contact surface adjustment fixing bolts 33 with respect to the vertical plate 12 b fixed to the slide 12. At the time of adjustment of the contact surface 20a, the contact surface adjustment fixing bolt 33 is loosened and fixed again after the adjustment.

  The front movable wedge 22 close to the moving blade 14 is moved up and down in the X direction by a push bolt 34 and a pull bolt 35 provided on the horizontal plate 12c fixed to the slide 12 above the movable blade. The pushing bolt 34 can push down the front movable wedge 22 by being screwed into a fixing nut 34a fixed to the horizontal plate 12c. The pull bolt 35 is implanted in the front movable wedge 22, and the front movable wedge 22 is raised by tightening the pull nut 35a.

  When the contact surface advances (when the cutting amount decreases), the pulling nut 35a of the pulling bolt 35 is loosened and the push bolt 34 is tightened, and the front movable wedge 22 is lowered. Thereafter, the pulling nut 35a is fixed. When the contact surface is retracted (when the cut amount is increased), the front movable wedge 22 is raised by loosening the push bolt 34 with respect to the fixed nut 34a and tightening the pull nut 35a. The push bolt 34 is tightened again to prevent loosening.

  On the other hand, a lever 23b protrudes from the back side of the rear movable wedge 23 on the back side, and a stud bolt 36 extending in the X direction is fixed to the lever 23b by a lower lock nut 36a. The stud bolt 36 is screwed into a rear lifting nut 37 that is rotatably supported by the vertical plate 12b, and its upper end can be locked by an upper lock nut 37a. When the contact surface advances, the upper lock nut 37a is loosened, the rear lifting nut 37 is rotated to raise the stud bolt 36, and the lever 23b is raised in the through hole 12d provided in the vertical plate 12b. The side movable wedge 23 rises in the X direction. Thereafter, the upper lock nut 37a is tightened and fixed. On the other hand, when the abutting surface is retracted, the upper lock nut 37a is loosened, the rear elevating nut 37 is rotated in the opposite direction to that during forward movement, the stud bolt 36 is lowered, and the lever 23b is provided in the through hole 12d provided in the vertical plate 12b. The inside is lowered, and the rear movable wedge 23 is lowered in the X direction. Thereafter, the upper lock nut 37a is tightened and fixed.

  By raising and lowering the pair of movable wedges 22 and 23 in the X direction, the position of the contact surface 20a is finely adjusted in the Y direction. Thereafter, the contact surface adjustment fixing bolt 33 is tightened.

  In this way, with the fine adjustment of the position of the contact surface 20a, the sponge titanium W supplied to the supply path 15 moves with the fixed blade 13 as the slide 12 moves up and down as shown in FIG. It is cut to a thickness L finely adjusted so as to be sandwiched between the blades 14 and the cut pieces are discharged from the discharge holes 16 and collected in, for example, pits P dug in the ground.

  Thus, in this embodiment, since the position of the contact surface 20a of the contact plate 20 can be finely adjusted using the wedge structure, there is no need to adjust by sandwiching the adjustment member as in the prior art. For this reason, what used to be a day work can be completed in a short time.

  Further, since the pair of movable wedges 22 and 23 are displaced while sliding the inclined surfaces 22a and 23a, the pair of movable wedges 22 and 23 can be obtained without making the movable wedges 22 and 23 excessively large. Thus, the position of the contact surface 20a can be finely adjusted while the contact plate 20 is stably held.

  Further, the abutment plate 20, the mounting base 30, the abutment surface adjusting portion 21 and the like can be integrally removed in the Y direction along the key 32, so that the maintenance work is very easy. .

  Therefore, according to this embodiment, since the position of the contact surface 20a of the contact plate 20 can be finely adjusted using the wedge structure, the position of the contact surface 20a is sandwiched between the adjustment members as in the prior art. There is no need for adjustment, and the adjustment work can be performed very easily.
