Fastener quenching device

Abstract

The invention discloses a fastener quenching device which comprises a quenching furnace. The quenching furnace comprises a discharging opening, a tubular spraying pipe is arranged below the discharging opening, a charging barrel is arranged below the spraying pipe and positioned in an oil collecting barrel, a support is installed in the oil collecting barrel, and the charging barrel is installed on the support and can rotate around the axis of the support; the side wall and the bottom of the charging barrel are both in a latticed shape, the charging barrel is controlled by a motor to rotate, and a closed oil cavity is formed in the pipe wall of the spraying pipe; a plurality of spray heads which are uniformly distributed are arranged on the inner wall of the spraying pipe, the spray headscommunicate with an oil cavity, and the oil cavity is connected with a cooling liquid box through a pipeline; and cooling liquid is contained in the cooling liquid box, the pipeline is connected withthe bottom of the cooling liquid box, a booster pump is installed on the pipeline, the barrel bottom of the oil collecting barrel is connected with a recycling pipeline, and the recycling pipeline isconnected with the cooling liquid box. According to the fastener quenching device, all-directional rapid quenching and cooling can be achieved for fasteners, so that the situation that the local temperature is too high due to agglomeration and the fasteners are prone to deformation is reduced.

Description

technical field [0001] The invention relates to the technical field of fastener processing, in particular to a fastener quenching device. Background technique [0002] Fasteners will retain a large amount of internal stress during processing, and quenching is required to eliminate the remaining strain. The traditional fastener quenching process is: batches of fasteners are heated in a quenching furnace, and then sent to a quenching tank filled with coolant for cooling. The disadvantage of this method is: when batches of fasteners enter the quenching tank at the same time, there will be instantaneous high temperature in the cooling liquid, and the temperature difference between the fasteners will be too large, resulting in uneven temperature of the fasteners. parts will be deformed. At the same time, a large amount of cooling liquid must be prepared in the quenching tank, and the fasteners will stick and take away part of the cooling liquid, causing the quenching tank to ne...

At the same time, a large amount of coolant must be prepared in the quenching tank, and the fasteners will stick to take away part of the coolant, resulting in the need to replenish new coolant in the quenching tank from time to time, resulting in a lot of waste
