Analysis of the identification method of new and old coiling machine by Liyang Juli

  The coiling machine is a large-scale mechanical equipment produced in the industry. In the process of purchasing the coiling machine, it is not only necessary to look at the overall technical parameters and performance of the coiling machine, but also to observe its appearance.

  The paint boundaries of different colors should be clear, and the non-machined metal outer surface of the coiler should be painted. Removable joints with joint surfaces shall be cut after painting and shall not be damaged when cut. The head of the countersunk head should not protrude from the surface of the part, and there should be no obvious eccentricity between the countersunk hole and the counterbore. The fixing pin tip slightly protrudes from the outer surface of the part. The bolt should slightly protrude from the surface of the nut, and the exposed shaft end should protrude the end surface of the containing part. The amount of protrusion is about the chamfer value. The exposed parts of electrical, lubricating, hydraulic and other pipes shall be arranged compactly and neatly arranged, and fixed by pipe clamps. The pipes shall not be twisted and folded and shall be rounded at the turning. The hose connected to the moving parts should be as short as possible and must not rub against other parts.

  In the process of purchasing the coiling machine, it should also look at the flatness of its surface. If the bending machine is not smooth, it is likely that it is the old equipment that has been processed and produced for many years, and has been reworked and assembled. Although the surface is coated with a layer of paint, it is still unable to get rid of the years of its use. The production of the annual high-profile bending machine will show a pitted surface, and the internal mechanical equipment will emit a very large process during the processing and operation. Noise, so be sure to pay attention to these problems when buying a coiler!
