Debugging method of helping machine before making shoes

General steps for debugging

First of all, according to the shape of the shoe last with good claw and claw and two claw and sweep knife and bundle, and then adjust the claw to the outer support table 10 mm, claw and inner support table, sweep knife ao into a straight line.

The claw disc to the middle position, take the yard shoe last put on the inner support platform, last to put positive, aligned with the claw center point and after the top plate into a straight line, and then according to the shape of the shoe last to adjust the radian, between the claws do not rub each other, but the gap should be as small as possible, gap small knot effect is good, claw clamping force should not be too large.

Start the manual switch of the sweep knife block, test the lowest point when the knife block drops, the lowest point of the sweep knife block should be above the claw, the distance from 0-1 mm is better, and pay attention to the knife block is easy to touch the claw, the gap is too large, and the platform is easy to hold the upper.

The original height of the inner brace is just right to put the upper into the claw. The horizontal height of the inner support plate shall be adjusted according to the bump and bump of the shoe last part. It is better to make the bottom of the shoe last parallel to the top edge of the sweeping tool. At this time, attention should be paid to whether the outer support plate is parallel to the sweeping tool.

The height of the inner support platform after rising is 2-3 mm higher than the upper edge of the sweep knife. If the support platform rises too high, it is not only easy to support the upper vamp, and the effect of forming is not good. Working height is too low easy to sweep the sole, hurt the vamp.

The inner and outer support platform shall rise to the top at the same time. Pressure of indenter. PVC upper pressure is generally set at 0-2kg, cm2.

When the sweep knife exceeds the claw mouth by 3 mm, the claw is released, and the outer support platform drops close to the tool mold by about 4 mm, and the inner support platform also drops when the tool mold is close to about 4 mm. The inner and outer support platform drops too fast and easily sweeps to the middle bottom plate, and the shoe lasts shakes. Too slow will spoil the machine parts.
