The invention discloses a cold roll forming technology for an escalator handrail bracket. The cold roll forming technology is operated according to the following steps: 26-28 roller beds are arranged in a stretching bending die, wherein each roller bed comprises bending die assemblies and straightening roller assemblies; the convex-concave degree of a roller sheet in each bending die assembly and a gap between two vertically arranged rolling heads are regulated to control a pressing bending deformation amount to a section bar by each roller bed to be 8-12 degrees; then, the section bar is caused to slowly enter the last roller bed from the first roller bed; each straightening roller assembly arranged between every two bending die assemblies is used for protecting the driving direction of the section bar. The section bar processed by the technology is free from surface damage, the product quality and the attractiveness degree of the formed section bar are improved, surface processing is omitted in a later stage, the working efficiency of escalator handrail bracket processing is integrally improved, and meanwhile, the cost is saved on the whole.

A vacuum processing apparatus includes a plurality of vacuum containers; a vacuumized transfer unit connected with the vacuum containers and having a transfer chamber; a plurality of lock chambers connected to the vacuumized transfer unit; a vacuumized transferring section arranged in the transfer chamber to transfer the sample between each of the lock chambers and each of the processing chambers inside the plurality of vacuum containers; an atmospheric transfer container having a space through which the sample is transferred under the atmospheric pressure; an atmospheric transfer unit arranged in the atmospheric transfer container and adapted to transfer the sample from a cassette; and a controller operative on the basis of schedule information of a plurality of operations to adjust the operations, the information including times of stagnation of the plurality of samples and set therefor.
