Material falling buffer of mesh belt type quenching furnace

Abstract

The invention discloses a material falling buffer of a mesh belt type quenching furnace. The material falling buffer comprises a balance shaft and an elastic thin plate, wherein the elastic thin plateis connected to one side of the balance shaft; two groups of counterweight assemblies and one reverse pull rod are arranged on the other side of the balance shaft; the reverse pull rod is located inthe middle; the two groups of counterweight assemblies are symmetrically arranged on both sides of the reverse pull rod; a spring pull rod is arranged below the counterweight assemblies and the reverse pull rod, and the counterweight assemblies and the reverse pull rod are connected together through the spring pull rod; a tension spring is mounted at each of two ends of the lower part of the spring pull rod; and the two ends of the balance shaft are connected with assembling assemblies. The material falling buffer disclosed by the invention is ingenious in concept and simple and reasonable instructural design; by use of elastic deformation of the elastic thin plate and the resistance of a quenching agent, a workpiece of which a matrix is still in a soft state is buffered in a falling process, so that the falling speed of the workpiece is effectively reduced, the cooling time of the workpiece in the falling process is prolonged, and impact to a mesh belt is greatly relieved; and therefore, the workpiece is no longer collided.

Description

technical field [0001] The invention relates to the technical field of mesh belt quenching furnace accessories, in particular to a mesh belt quenching furnace blanking buffer. Background technique [0002] Mesh belt quenching furnace is a type of heat treatment furnace that uses mechanically driven intermittent or continuous mesh belt to control the temperature of the workpiece in the heating zone, and then meets the requirements of the quenching process. It is suitable for the heat treatment of small and medium-sized parts in batches. It can automatically and continuously complete a series of processing processes such as heating, heat preservation, quenching agent cooling, workpiece extraction from the quenching agent, cleaning and drying. It has the advantages of stable process control and high production efficiency. . [0003] The mesh belt quenching furnace is mostly used for heat treatment of small and medium-sized workpieces. It is not suitable for heavy workpieces. T...
