Problems solved by technology

However, in the existing quenching pool, after the workpiece enters the pool body, the quenching medium is still, so that a layer of steam film is easily formed on the surface of the workpiece, which will affect the transfer of temperature, and it is easy to cause the workpiece to be chilled. Quenching hot cracking will cause the workpiece to be scrapped, and the temperature of the quenching medium cannot be transmitted evenly, which will easily affect the metallographic structure and hardness of the workpiece

Embodiment 1

[0019] Such as figure 1 and figure 2 As shown, a quenching pool for small castings includes a pool body 1, and a casting loading basket 2 is provided inside the pool body 1. The casting loading basket 2 includes a mesh basket body 21 and a handle 22; The workbench, servo motor 3 and lead screw 4 are placed on top. The servo motor 3 is located on the workbench. On the bar 4; the workbench includes a table top 51 and a support frame 52, the screw 4 includes a screw 41 and a nut 42, the screw 41 is distributed along the vertical direction, and is connected with the output shaft end of the servo motor 3 , the support frame 52 is provided with a slideway, and also includes a horizontally arranged sliding rod 6, two sliding rods 6 are evenly distributed along the circumference of the nut 42, one end of the sliding rod 6 is fixed with the nut 42, and the other end is slidably connected with the slideway ; Two handles 22 are also provided, which are fixed with a sliding rod 6 respe...

Embodiment 2

[0022] Such as image 3 and Figure 4 As shown, the difference between this embodiment and Embodiment 1 is that a filter residue net 7 is also provided in the pool body 1, and a baffle plate 8 is provided around the filter screen 7, and the baffle plate 8 is connected to the handle 10 through the connecting rod 9. connected. The filter residue net 7 is slightly smaller than the size of the bottom of the pool body; the handle 10 is placed on the edge of the pool body 1 to facilitate the removal of the filter residue 7 net.

Embodiment 3

[0024] The difference between this embodiment and Embodiment 2 is that there are two casting loading baskets 2 .

Abstract

The invention relates to the field of quenching tanks, in particular to a quenching tank for small-sized castings. The quenching tank comprises a tank body, a workbench, a servo motor and a lead screw, wherein casting loading baskets are arranged inside the tank body, each casting loading basket comprises a reticular basket body and a handle, the workbench is positioned on the tank body, the servo motor is positioned on the workbench, the lead screw is arranged at the output shaft end of the servo motor in a transmission connecting manner, and the basket bodies are fixedly arranged on the lead screw; after the adoption of the technical scheme of the quenching tank for small-sized castings, the quenching temperature can be uniformly transferred.

Description

technical field [0001] The invention relates to the field of quenching pools, in particular to a quenching pool for small castings. Background technique [0002] Quenching is a metal heat treatment process in which a metal workpiece is heated to an appropriate temperature and maintained for a period of time, and then immersed in a quenching medium for rapid cooling. The purpose of quenching is to transform supercooled austenite into martensite or bainite to obtain martensite or bainite structure, and then cooperate with tempering at different temperatures to greatly improve the steel's rigidity, hardness, and durability. Wear resistance, fatigue strength and toughness, etc., so as to meet the different requirements of various mechanical parts and tools. Quenching can also be used to meet the special physical and chemical properties of some special steel materials such as ferromagnetism and corrosion resistance. [0003] The quenching pool is an essential equipment for the ...
