Embodiment Construction

[0014] Such as figure 1 It is a structural schematic diagram of the present invention, a process for processing nylon wheels for elevators, and its processing flow is: melting caprolactam-weighing-pre-vacuumizing-adding quantitative NaOH pigment-vacuumizing-centrifugal casting, mold heating-demolding-blank heat treatment- Finished product processing - inspection and storage.

[0015] Among them, centrifugal casting, blank heat treatment, and finished product processing are the key steps of the present invention. The steps of melting caprolactam, weighing, pre-vacuumizing, adding quantitative NaOH pigment, vacuuming, mold heating, and demoulding are similar to traditional methods, so no longer repeat.

[0016] First, solid curing agent MSCP2013 is added during centrifugal casting, and the centrifugal casting time is 120s. The solid curing agent MSCP2013 is non-toxic, easy to measure and weigh, and the MC nylon wheel formed after polymerization is also non-toxic and has high m...

Abstract

The invention relates to the technical field of elevator nylon wheels, in particular to an elevator nylon wheel machining process. The machining process comprises the machining flows of fusion of caprolactam-weighing-forvacuum-adding of quantitative NaOH pigment-vacuumizing-centrifugal casting and mold heating-mold release-blank heat treatment-machining of finished products-inspection and warehousing; in the centrifugal casting, a solid curing agent MSCP2013 is added; in the blank heat treatment process, cast nylon wheels are dipped in an oil-state medium; and the machining of finished products only comprises the steps of grooving of blanks-rough turning-finish turning-turning of rope slots-turning of snap spring grooves-chamfering-inspection. The elevator nylon wheel machining process replaces a traditional process; and the whole service performance of products is largely improved.

Description

technical field [0001] The invention relates to the technical field of elevator nylon wheels, in particular to a processing technology for elevator nylon wheels. Background technique [0002] Nylon wheel blank is a chemical product formed by melting the raw material caprolactam and vacuumizing it, mixing it with curing agent and pouring it into a special mold for polymerization. The traditional nylon casting formula generally uses curing agent TDI. The curing agent TDI has the following disadvantages: poisonous; easy to spill, easy to residue and inaccurate in measurement and weighing; general mechanical performance indicators of MC nylon wheels formed after polymerization. [0003] In order to eliminate the internal stress of the cast nylon material and increase the dimensional stability, the cast nylon wheel is often immersed in hot water or other liquid media that do not affect the performance of the cast nylon. The traditional heat treatment medium for elevator nylon wh...
