Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides equipment for chopping titanium and other gold scrap materials, particularly scrap of medium or thick plates, into small chips sized for remelting.

Titanium has high strength per unit weight, so it is used as a strength alloy! I! In addition to being used as a constituent material for ruts, etc., it is also widely used in various chemical industry fields due to its excellent corrosion resistance against the corrosion effects of cypress shavings. Because it is a material, it is worth collecting as much scrap material as possible, subjecting it to remelting, and reusing it as recycled titanium material.

Titanium has a very high melting point (1725°C), so it is difficult to dissolve, is highly active at high temperatures, and reacts extremely easily with oxygen, nitrogen, and sulfur, and its impact properties decrease when hydrogen is mixed in, so it should not be used in an inert gas atmosphere or It is gradually melted using a consumable electrode method under vacuum. Therefore, in order to subject titanium scrap to such remelting, it is necessary to use a small H1 example, 20 mm flat type, which is easy to remelt and can be continuously cleaned by removing impurities such as oil and fat.
It is necessary to pre-cut #ll into 1 ln x 20 n+m % piece chips.

A medium plate with a thickness of 2 to 6 Trm or J! It is difficult to cut relatively large scrap materials made from jL& titanium plates into pieces because the shear resistance of titanium is generally large and the residual M stress at the time of l7JWit tends to cause spring punctures, warping, and twisting. encounters various difficulties with VcM. Conventionally, this type of scrap board material was divided into thin 1itrVi, the first 17 IIFT process using an individual large jarring machine, the continuous image process, the second 9 cutting process using an individual small jarring machine, and the selection of cuts H outside the specified dimensions. Manual adjustments are made throughout the process, but there are many losses due to excessive cutting, insufficient cutting, and improper cutting, and the process is complicated and the work is inevitably inefficient. Ta.

The present invention provides a rational and efficient vcUJ method for producing small chips of a certain size suitable for remelting from thick plate scraps.
It is based on the technology or equipment that can cut
It is configured to work slowly at one time, so that orderly shredding can be carried out. That is, the structural features of the super IwT conveying device of the present invention include a first shearing machine that cuts medium and thick plate scrap material into strips and materials of a certain narrow width;
A conveyor is provided to receive the strip-shaped plate material falling below and convey it in the longitudinal direction, and on the conveyor, a plurality of groove paths r are created by a guide plate for use in the dormitory, and the shearing section of the first shearing machine 11+ and the groove [IiI] VC 1st shear - 1st machine's shear tt/r Sakusuke, connected to it and reversed distribution is da/no (board? provided, roughly the position of the conveyor head - VC 2nd
The point is that a shearing machine is provided, and a pinch roll is provided at 1111 between the conveyor and the second shearing machine for feeding the strip-shaped plate material in conjunction with the shearing operation, so that the strip-shaped plate material is thinned into rectangular H-shaped chips.

For unexploded BAs, a guide plate for laying down is installed on the guide plate for clear guidance, and even if there is bending or twisting in the band-shaped plate material, t14
This includes a configuration that always holds the material horizontally in the narrow width direction on the road and smoothly transports and feeds it to the second pruning machine.

Hereinafter, the present invention will be explained in more detail with reference to Embodiment R (specifically and in detail #I vc g51) of the attached drawings. 8) shows its distribution from the side view of the damper, Fig. 8 (b) shows the direction from the II-Ill line, and Fig. 4 U) shows the top guide of the conveyor. Figure 4 (b) is its front view.

In order to carry out shredding using the apparatus of the present invention, thick plate scrap materials of various dimensions and thickness of 2 to 6 mm generated in various processing factories are cut in advance to a constant width +000 mm Vr- and then supplied. This width direction is the narrow strip 8/I of the material described later.

In the above 1) M 1000 iom, place the thick plate scrap material on the turret (2), feed it manually or by self-feeding until it hits the sizing stopper (5) K, and then step on the foot switch to activate the air clutch uQ. By connecting and transmitting power, the blade (4) is moved up and down by one stroke, and the scrap material is shaped into a narrow strip with a width of, for example, 20 min. 20 am x 10
The strip plate It with the specified size of 0(l min has a lower Vcl/

In order to minimize bending, warping, and twisting in the longitudinal direction of the strip material, the shear angle of the shearing tool, that is, the inclination angle of the movable blade (4) with respect to the identification blade (3), is minimized by VC. This shear angle Fi of about 40 minutes is appropriate.

1st! Below the glIIT machine (1), a belt conveyor-type conveyor will be installed to receive the strip-shaped plate material that is peeled off and convey it in the longitudinal direction toward the mincing shearing machine (@2M2J section) ◎ Conveyor @ top In this example, we are transporting strips and materials within the dormitory.In this example, we attach four guide plates parallel to the running direction to such an extent that their lower ends touch the conveyor belt. Set it up in the upper and both outer positions of Konobeya! #i in this example
Create two channels (A) and (B).

In order to distribute the strip-shaped plate material from the first shearing machine (1) into grooves 0) and (B) and insert it into the shearing section and grooves (A) and (B),
) A damper plate σ41 is provided between &. Danno Hikiita (
B) is a groove (A) shown in Fig. 8 (0) (B) K. In the position relative to (1), the lower end is pivotally supported by the shaft 4, the upper part is connected to the air cylinder (6) K, and the groove is in contact with the stoppers qη at both ends. 0 and the first !l!Jfr machine (
At the end of the 1lII stroke of the movable blade (4) in 1), an electric signal is sent to activate the air cylinder (G) to perform a reversal, and the strip-shaped plate material that falls one after another is alternately K ts path (
Include A) and (B) and KML. OΦ is a guide that cooperates with the damper plate.

Near the conveyance end of grooves WJ (A) and CB), as shown in Figure 4 0) (B) K, there are 6 grooves @ VC and two opposite-hand guide pieces (to). It will be housed in So.

These guide pieces (G) should be used in case the band-shaped plate material is bent or warped.
When trying to take the posture of 20 mm narrow turning vertical 1u due to twisting, it is regulated to be horizontal in the narrow width direction to facilitate guidance and feeding toward the second shear +1uu.

In order to feed the strip material to the second shearing machine υ, an auxiliary roller for tightening is installed on the head pulley QIK of the conveyor (6). Pinch roll C! Set υ. The strips and nails are conveyed on the conveyor (B) through the grooves (A) and CB).
First, it is conveyed by the conveyor (B) and auxiliary roller (E), and then by the pinch roll Glυ, it is sent by itself to the pruning machine of the second pruning machine Oυ at a predetermined speed.

In front of the shearing part of the 241iI cutting flk (b), attach a material holding plate) to the material holding plate. In the second shearing machine (b), the upper q# blade (c) is the sliding guide 11 OK for the lower fixed blade ■. The three movable blades (c) move up and down in the dormitory to perform shearing, and the blades (c) move from the electric motor (to the electric motor) to the belt transmission mechanism (to the -center crankshaft) to the eccentric crank (to the eccentric crank) to create a U-wound at high speed. roll(
(b) is driven by a continuously variable transmission and chain transmission mechanism (not shown) at a speed that is the same as the operating speed of the movable blade (iv), and is fed into the shearing section of the second shearing #T machine by a series of both speeds. The gap between the EAT i blade (2) ♂ and the fixed blade ■, which is loaded into the belly and transported to the next process, can be adjusted to a dimension Ka & 1 corresponding to the thickness δ of the cut plate material. Movable blade (c)
': Lower vJ speed and pinch roll 6! The shear angle is set to zero in order to keep the feeding speed of v and LS in sync.

In this example, two narrow strip-shaped plates are fed parallel to each other one after the other through the channels (A) and (B) on the conveyor (6). But 1
When the two strip-shaped plates pass through the pinch rolls (2), the feeding force is lost, so this strip-shaped plate temporarily stops inside the material holding plate (2) between the ten-piece (c) and the pinch rolls (V). This strip-shaped plate material is pushed forward by the arrival of the next strip-shaped plate material sent at intervals, and the shredding continues. The following effects can be obtained. In other words, thick plate scrap material, such as titanium, which is difficult to finely cut, is first cut into small strips of 1/I# and then shredded into chips of a predetermined size, so that the shredding can be done in an orderly manner. This eliminates the need for unnecessary cutting, requires minimal assistance, and reduces wear and tear on the equipment and blades.
It is possible to cut continuously without being disturbed by warpage, twisting, etc. Also, the shredding chips have uniform dimensions and are of good quality, and there is no need for sorting, which is advantageous between uses. The cutting operation can be performed automatically or semi-automatically, so there is less manual operation and shredding can be done safely and efficiently.
