Abstract

PURPOSE:To perform with high precision side grinding of sharp band saw by performing spring setting breadth grinding in two steps of rough machining and finishing and also controlling generation of heat as much as possible. CONSTITUTION:A pair of grindstones 19, 19' respectively equipped with motors 18, 18' are symmetrically provided slanting at a predetermined ideal spring setting angle and interposing a band saw 1 between them. One side part in the direction of movement of direct-acting cam 15 is formed as a slant part 15a for rough machining, and a medium formed as a parallel part 15b of a definite breadth, while a base end part formed as a slant part 15c for finishing. An interval between a pair of grindstones is changed in the same way in two stages of rough machining and finishing through a cross-fed mechanism (unillustrated) and grinding of the spring setting breadth is performed efficiently.

Cut it and finish it in the shape of 2D A, BVC7i. In addition, the tooth throat 3 and both sexes 4 are polished with an automatic sharpening stone, and the edges are polished with a side surface grinding process 'AU'.

In other words, the pair of grinding wheels 19 and 19' approach each other in a symmetrical manner as the pressing cam [1] 5 moves repeatedly, and in conjunction with this, the band saw 1 moves intermittently. As a result of vertical VC feed, the width (++F) of 41 pieces and 1111 songs is reduced.

However, in the case of the conventional band saw (ttl! tin grinding finishing equipment + i), the cutting (feeding) of the grinding wheels 19 and 19' is done at a constant speed for rough cutting and finishing at different speeds, which generates a lot of heat. Stellite's hardness) W decreases, and the obi belt is cut! It is easy to remove the taste and the whetstone is 19.
, +9' l wear was severe, and its wear and tear was short, making daily maintenance management troublesome.

In addition, the grindstones 19 and 19' wear irregularly because only their -feet σ] surfaces hit the side surfaces of the band saw, so the grinding angles are shaped like a recess or a Y-shape as shown in Fig. 3. Not only was it difficult to do, but it also killed 8 students who had 11 bruises. To be more specific, the shape of the bruise is 9〈, and the grinding is not perfect, so it is difficult to make full use of the Stellite pouring sink, and if the grinding is even slightly worn, the taste will be worse. However, since it has to be replaced for a long period of time, and it has to be replaced 3 or 4 times a day, it is a cause of decreased productivity. In addition, there were also drawbacks such as bending in the grinding process, poor grinding texture, and a decrease in yield.

Purpose of the invention Therefore, the purpose of the present invention is to grind
It is carried out in two stages: drying and finishing, and therefore,
1 wheel drive [Audibly suppressed, the performance of Stellite was sufficiently improved, and the cutting 7 blades 1 blade saw side 1 T 11 grinding can be carried out with high passion and purpose. An object of the present invention is to provide a band saw one-law surface E-one finishing device with an improved configuration.

Structure and Effects of the Invention In order to achieve the above-mentioned objects, the band saw side surface grinding and finishing device of the present invention has a wide sloped part for rough cutting on one side in the direction of movement of the direct-acting cam, and a parallel part on the middle part. and form it as an inclined part for finishing on the other side.

If the cam follower 3 does not come into contact with the disk cam 1C1', only the direct-acting cam 15 will be able to perform the width 0F till.

In addition, here, the 1311 continuous action of the direct-acting cam 15 and the cam 10' and the working of both of them will be explained together with reference to Figures 1 to 16. For example, it is as follows.

First, as shown in FIGS. 11A and B, the disk cam 10' rotates approximately 60 degrees clockwise, and as the cutting rod moves forward, the cam follower 36.16' is tilted around 1 for rough cutting. A pair of whetstones 19 are located near and along part 1savc.
, 19' (Asa 111i information) has narrowed, and the stellite 20 on the scale saw 1 has entered the stage of rough cutting on all sides. ゛During this period, the cam follower 3 is in the cross-section position, so vertical feeding is not performed. I haven't.

Next, FIGS. 12A and 12B show a stage in which the rotation angle of circle 4 to cam IO' has further advanced by 45 degrees (total rotation angle 1056). That is, the cam follower 16° 16' comes into contact with the parallel part 15h from the end point z1 of the oblique part 15a for rough cutting in the direct-acting cam 15, and the width of the body to complete the first stage of cutting is determined to be 1.
1111 Surface grinding (rough cutting) is being carried out.

At this time, the cam follower 3 for the disc cam 10' is also in contact with the arcuate concave surface 111a, and the first vertical reciprocating motion against the pair of grinding wheels 19°19' is being carried out with a stroke of approximately 10 degrees. . , -11, etc., the end point z1 of the shaving slope M515a on the direct-acting cam 15 and the starting point y1 of the arcuate concave surface 10a on the disc cam 10' are the same distance 2'.

In other words, a pair of 14 (stones 19 and 19' are
Keeping the set Vc, determined C-, and n as shown in the figure, the adjustment width is approximately 101M to the position indicated by the dotted line in the same figure.
It is transported back and forth (l secondary transport), and side surface (if) cutting is performed. Therefore, r, tQ stone 1 is removed from stellite 2.
9゜1tal grinds by making land contact in a wide area, so grinding wheel 1
9゜19' local wear should be prevented as much as possible.
The ideal shape of the asarif shown in Figures A and B lies in its sharpness, and it takes effort to grind it well.

The cam followers 16 and 16' have already moved forward about 15 steps, and the cam followers 16 and 16' are still in contact with the parallel portion 15i), maintaining the first stage σ] width IJ. However, the cam follower 3 for the disc cam l()' has already passed through the first arcuate concave surface 10a and is in contact with the arcuate portion]Oc having a constant radius.

Incidentally, FIGS. 14A and 14B show the stages of the rotation angle of the disc cam IO'σ of 195°. 121J, the direct drive cam 15 has exceeded its 6iJ advance limit (the Z point of the crank 10) and has entered the go-around rod a little. Cam followers] 6 and 16' come into contact with the finishing inclined portion +5c to determine the zero width of the bruise in the second stage, and the side surface grinding (finishing) is in progress.

The cam followers 16 and 16' are brought into contact with the rough-cutting inclined portion 15a at approximately the 11th position, and the pair of grinding wheels 9 and 19' are fully opened to prepare for grinding. This 11II surface grinding and finishing device according to the present invention prevents irregular wear of the grinding wheels 19, ] 9', and keeps the width of the heel 11 and the angle of the heel IJ in an ideal shape. Can perform side grinding. Therefore, by making full use of Stellite's performance, you can obtain a band saw with a good cutting surface and no cutting curve. 1?
