Problems solved by technology

[0002] The power take-off output gear of the engine requires carburizing and quenching treatment. The original furnace adopts the same direction and is placed horizontally on the ring tooling, and the tooling itself is relatively heavy, so the amount of furnace loading is relatively small, and the handling is laborious and labor-intensive.

Embodiment Construction

[0013] The engine power take-off output gear is ideally carburized and quenched vertically to reduce the amount of deformation. At the same time, in order to ensure uniform carburization and quenching of all parts of the gear, under the constraints of space and furnace weight, install as many gears as possible to reduce the weight of auxiliary tooling and its volume. The existing tooling is placed in one direction, which will inevitably cause the teeth to be on the same plane, which takes up a lot of space, and the thermal field in the furnace is unevenly distributed, which affects the carburizing and quenching quality of the gears.

[0014] Such as figure 1 As shown, the tooling 2 is integrally processed, and the 4mm gap 1 on the upper part makes the carburizing atmosphere and quenching oil pass smoothly.

[0015] Such as figure 2 As shown, the tooling 3 is welded by the chassis 6 and the sleeve 5, and the hole 4 with a diameter of 8 mm in the middle of the sleeve 5 makes ...

Abstract

The invention aims to provide thermal treatment carburization charge tooling capable of vertically placing axle gears. The technical scheme is that: two types of the thermal treatment carburization charge tooling are utilized; tooling (2) is integrally processed; a 4 mm notch (1) is formed on the upper part of the tooling (2); tooling (3) is formed by welding a chassis (6) and a sleeve (5); and a hole (4) with 8 mm diameter is formed on the middle part of the sleeve (5). A short axle end of the gear is vertically placed in the tooling (2), and a long axle end is placed in the tooling (3); the tooling (2) and the tooling (3) are alternately arranged on a charging basket bottom for carburization quenching treatment; and after the quenching, the gear is fetched out, and the tooling (2) and the tooling (3) can be reused. When the tooling is used, the gear can be vertically placed in the tooling, the charge amount is greatly increased and the thermal treatment carburization quality is guaranteed.

Description

technical field [0001] The invention relates to a furnace loading tool for heat treatment of shaft gears, in particular to a carburizing furnace loading tool for heat treatment. Background technique [0002] The power output gear of the engine requires carburizing and quenching treatment. The original furnace adopts the same direction and is placed horizontally on the ring-shaped tooling. The tooling itself is relatively heavy, so the amount of furnace loading is relatively small, and the handling is laborious and labor-intensive. Contents of the invention [0003] The purpose of the present invention is to provide a heat treatment carburizing furnace loading tool capable of vertically placing shaft gears, so as to solve the above technical problems. [0004] The technical solution adopted is: the heat treatment carburizing furnace tooling includes two kinds of tooling, the tooling (2) is processed in one piece, and is provided with a gap (1) of 4mm; the tooling (3) adopts...
