How to solve the problem of the special screw flat tail? The general analysis has the following reasons.
Screw Series 1. The back angle of the spiral pile is too small, and the material, in both cases, the back angle of the diamond file is pushed forward in the direction of the altitude back angle, the back angle increases, the material is less, and there is a small loose tooth machine that can be adjusted to make tip of the head
To less material is also possible, for example: the end of the material, the formation area, the tail can solve this problem.
2. Controlling the length of blank nails is also very helpful to solve the problem of wake.
3. The tail teeth have a front. The solution is the same as that of the tail teeth. The key point is to control the length of the light nail to solve the front of the tail teeth.Security Screws
4. Thread heavy teeth: Generally, there are several situations:
(1) The tooth profile is not aligned properly when adjusting the machine tool. When the thread is formed by extrusion, it is easy to cause heavy teeth. Try moving the flap up and down a few times and this usually fixes the problem.
(2) When the tooth plate adjustment machine is not placed on the same surface, the two pieces will also cause uneven extrusion, which will easily cause tooth weight:
(3) When adjusting the machine, the gap on the sliding surface of the moving trigger is too large, and the vibration is too large during extrusion, which may easily cause tooth weight;
(4) The pressure in the feeding area of the regulator is too tight, which can easily cause tooth weight;
(5) When the anti-slip teeth of the dental plate are carved too deeply, the treatment method is to use a triangular withering file to insert the anti-slip teeth on both sides of the alveolar along the direction of the alveolar, so as to smooth the burrs and reduce the friction.
Special screw detection method
.Stainless Steel Screws 1. Measuring tool method: the amount used has micrometers, vernier calipers, plug gauges, etc.:
2. Magnetic method: The magnetic method measures the thickness of the coating layer, which is a non-destructive measurement of the non-magnetic coating layer on the magnetic substrate with a magnetic thickness gauge:
3. Microscope method: place the etched fastener on a metallographic microscope with a micrometer eyepiece to enlarge, and measure the thickness of the coating on the section.
4. Chronograph liquid flow method: use a solution that can dissolve the coating to flow on the partial surface of the coating, and calculate the thickness of the coating according to the time required for the local coating to dissolve.
