Abstract

The utility model belongs to a metal cutting anti-swarf device, comprising a top runner plate 6, a bottom runner plate 5, a swing rod 4, a swing base 3, a column base 2, etc. The top and the bottom runner plates are vertically crossed, the intersection line can form a 30-60 DEG included angle with the bottom edge of the top runner plate, and the runner plates can be connected with the swing base 3 via the swing rod 4 and can horizontal turn around the center of the column base 2. The utility model has the advantages of small size, good anti-swarf effect, convenient operation, time saving and labor saving, the anti-swarf runner plates can be one-time targeted as requirements, and the utility model is an ideal anti-swarf device for general lathes with various models.

Description

Swing safety chip guard

The utility model belongs to the metal cutting protector, says it is a kind of anti-bits of metal cutting device that is used for lathe more detail.

Current, not anti-bits device on domestic most of engine lathe.Improve forming on the basis that the last folding formula retaining bits cover that the Sino-Japan joint technical school in Shenyang uses is a Soviet Union IK62 lathe retaining bits cover prototype, light than the former, but when measuring workpieces, need to use arm strength will prevent considering to be worth doing upwards upset of runner plate, the operator is relatively more tired.The retaining bits runner plate of Shenyang first Machine Tools Plant design is to be fixed on the four bar extension spring structures.Appoint on the position unexpectedly though this retaining bits mirror can be moved retaining bits runner plate to, because the pulling force effect of spring, retaining bits runner plate is difficult to one-time-reach-place.Moreover, when different-diameter on workpiece of cutting or continuous building up by welding, need repeatedly to adjust to keep off the runner plate that rubs, could guarantee the anti-effect of considering to be worth doing, use cumbersome.

The purpose of this utility model provides the anti-bits of a kind of swing type mirror.This anti-bits mirror volume is little, in light weight, and retaining bits runner plate can once be adjusted to the right place according to need of work, and is easy and simple to handle, saves time, laborsaving.

The utility model is achieved in that the anti-bits of swing type mirror structurally is made of parts such as column, column base, fork, runner plate, alignment pins.Runner plate divides goes up runner plate and following runner plate, and the plate face of two runner plates intersects vertically up and down.Like this, both can block the smear metal of upwards collapsing that is produced by cutting, and can block not only and collapse to the claw but also the smear metal of being returned by bounce-back, anti-bits performance is good.Runner plate connects by fork and swing seat, rotates around the column base central horizontal, operates, and is very flexible, light, as long as light one group with have gentle hands, can put in place.Column lower end has fixture, can will prevent considering to be worth doing mirror and be fixed on the middle carriage of lathe.During work, anti-bits mirror and cutting tool are synchronized with the movement, and place retaining bits position all the time.Though be that cutting depth changes or cutting end face continuously, do not need to adjust again anti-bits position.

The utility model can solve the anti-bits problem of lathe metal cutting effectively, put down engine lathe and used a big obstacle of (the best) cutting data rationally, the application of cutting data rationally will increase the ratio of effective merit in cutting, thereby can raise labour productivity more than one times saves energy 26～40%.

Below in conjunction with accompanying drawing the utility model is further described.

Parts position on the accompanying drawing is in retaining bits position.

Fig. 1 is a front view of the present utility model.

Fig. 2 is a vertical view of the present utility model.

Among Fig. 1, the 1st, the column of anti-bits mirror; The 2nd, column base; The 3rd, swing seat; The 4th, fork; The 5th, lower runner plate; The 6th, upper runner plate; The 7th, mirror holder; The 8th, month alveolus; The 9th, alignment pin. Lower runner plate 5 and upper runner plate 6 all adopt tempered glass or methacrylate sheet to make. The plate face of upper runner plate is the plane, and upper rib is camber line, and lower rib is straight line. The plate face of lower runner plate 5 is the folding face. Upper runner plate 6 intersects vertically with lower runner plate 5, intersection becomes 30 °～60 ° angle with the lower rib of upper runner plate 6, and the best is 45 ° of angles. The upper surface of column base 2 Have the moon alveolus 8 of half garden shape. Alignment pin 9 is housed on the upper surface of swing seat 3. Alignment pin 9 cooperates with a month alveolus 8, and swing seat 3 is horizontally rotated in certain scope around the center of column base 2. Runner plate 6 is crossed fork 4 swing seats 3 knots on the lower runner plate 5, and rotating angle around column base 2 central horizontal is 0 °～90 °. 1 time end of column is provided with fixture, can will prevent considering to be worth doing mirror and be fixed on the suitable position of lathe.

The anti-bits of swing type mirror application example:

Workpiece material: 45# hot rolling structural carbon steel

Lathe tool type: TI605F, material: YT14

Cutting data=

Cutting data	One group	Two groups
			aP
^mm	3	1
			f ^MM?/r	0.5	0.35
V ^m?/mn	113	150

The smear metal whereabouts:

Use its smear metal major part of first group of cutting data to collapse to the lathe tool major flank, seldom part upwards or towards operator's direction collapses.

Use its smear metal of second group of cutting data upwards most of and on a small quantity to operator's direction collapse, small part collapses to the lathe tool back.

Retaining bits rate: 100%

The utility model can be widely used in the engine lathe of various models.

Claims

1, a kind of anti-bits mirror that comprises anti-bits plate, connecting rod, fixture, it is characterized in that: a, runner plate 6 directly intersects on the following runner plate 5, and 6 times ribs of intersection and last runner plate become 30 °～60 ° angle: b, following runner plate 5 and last runner plate 6 connect by fork 4 and swing seat 3, rotate around the central horizontal of column base 2.
