Tungsten and molybdenum rolling machine

Abstract

The invention relates to the technical field of rolling equipment, in particular to a tungsten and molybdenum rolling machine. The tungsten and molybdenum rolling machine comprises a rack, a plurality of horizontal rolling devices, a plurality of vertical rolling devices, an emulsion cooling mechanism and a plurality of thin oil cooling mechanisms. The outer sides of two eccentric wheels are each provided with two symmetric roller spacing adjusting mechanisms, each roller spacing adjusting mechanism comprises an adjusting screw rod, an adjusting nut and a connecting block, a mounting block is arranged on the outer side of each eccentric wheel, the adjusting screw rods and the adjusting nuts are arranged in the mounting blocks, the adjusting nuts are arranged in the mounting blocks in the radial direction in a limited mode, and the adjusting screw rods and the adjusting nuts are arranged in cooperation. The connecting blocks are rotatably connected with the adjusting nuts through connecting rods, one ends of the connecting rods are fixedly connected with the adjusting nuts, one ends of the connecting rods are rotatably connected with the connecting blocks, and the connecting blocks and the connecting rods are rotatably connected with the eccentric wheels through connecting pins.

Description

technical field [0001] The invention relates to the technical field of rolling equipment, in particular to a tungsten-molybdenum rolling machine. Background technique [0002] At present, domestic equipment for processing metal workpieces includes wire rolling machines and wire drawing machines. Since the processed metal workpieces are all thinner wires, the wire rolling machines use large motors and heavy multi-stage transmission mechanisms. The mechanisms are respectively driven by mechanized gears or belts, so that the rolling speeds of the processing devices and transmission mechanisms at all levels are limited. This type of unit can only roll a single material. For example, it cannot be rolled by a copper rod rolling mill.

Problems solved by technology

[0002] At present, domestic equipment for processing metal workpieces includes wire rolling machines and wire drawing machines. Since the processed metal workpieces are all thinner wires, the wire rolling machines use large motors and heavy multi-stage transmission mechanisms. The mechanisms are respectively driven by mechanized gears or belts, so that the rolling speeds of the processing devices and transmission mechanisms at all levels are limited. This type of unit can only roll a single material. For example, it cannot be rolled by a copper rod rolling mill. Aluminum rods, domestic special-shaped materials must be rolled by specific rolling mills, and these existing units cannot process special alloy materials; at the same time, the general unit is driven by a large transmission box to drive multiple rolling devices, so the current and voltage consumption is too large and wasteful Energy; the transmission mechanism in the transmission box wears out after long-term use, so that during the processing, the unit will be unstable and push-pull, which will affect the quality of the processed product; in addition, the processing device and transmission mechanism of the existing unit The setting is unreasonable. When processing different materials, there is a shortcoming that it takes too long to change the mold, which increases the input of extra manpower, and the rolling process is carried out by two rolls in the rolling device. The two rolls The distance between them determines the degree of rolling. The distance between the rolls of the existing rolling mills is fixed and cannot be adjusted, which limits the effect of rolling and the flexibility of rolling to a certain extent.
