Composite spring buffer device for preventing bumping in oil tank

Abstract

The invention relates to a composite spring buffer device for preventing bumping in an oil tank. The buffer device assembly is located between a dropping hopper and the lifting mesh belt of the oil ink; the buffer device assembly is composed of a spring, a receiving buffer board, a receiving mesh belt, a steel wire rope, a receiving mesh belt guide rail, a receiving board holder, a spring fixing base plate and a spring retaining base; the top of the receiving buffer board is fixed above the receiving board holder by use of a fastener; the spring, the spring retaining base and the spring fixing base plate are mounted on the lower part of the receiving buffer board; the spring is located between the receiving buffer board and the spring fixing base plate; the spring fixing base plate is fixed on the spring retaining base; and the receiving mesh belt is mounted on the upper part of the receiving buffer board. The composite spring buffer device has the beneficial effects that a dropping workpiece is buffered halfway by use of the elasticity of the spring steel buffer plate and the spring, the mutual bumping of the workpieces is solved, the product quality is improved and the product rejection rate is reduced.

Description

technical field [0001] The invention belongs to the technical field of a buffer structure in a quenching oil tank in metal heat treatment, and in particular relates to a composite spring buffer device for preventing bumps in an oil tank. Background technique [0002] In the existing more advanced structure, after the workpiece is heated in the quenching heating furnace, it falls into the quenching oil tank for quenching. Therefore, the temperature of the workpiece is at 800°C, the surface hardness is very low, and the falling speed is also fast. In the traditional quenching In the oil tank structure, it is very easy to collide with the workpiece that fell earlier or the lifting mesh belt stopper that received the material, causing surface bumps. The surface bump damage will cause a series of problems such as increased processing volume and damage to the abrasive tool in the subsequent grinding process. If the bump damage occurs on the non-processed surface of the workpiece ...
