Technical field

The invention belongs to metallurgical sample experiment rooms to detect auxiliary tool manufacture field, be suitable for ￠ 20mm~￠ 150mm balls The clamping of shape sample, annealed, normalizing, the technological operations such as quenching.

Background technology

Heat treatment is so that the institutional framework of steel is changed, to obtain by the operating method of heating, heat preservation, cooling Need a kind of processing technology of performance.Generally comprise other techniques such as annealing, normalizing, quenching, tempering.

Spherical sample is when being heat-treated, since the techniques such as sample is annealed at high operating temperatures, normalizing, quenching are grasped Make, sample easily rolls in operation, not only influences the heat treatment process effect of sample but also easily causes the person Injury and equipment breakdown, it requires must have special tool to be clamped, and spherical sample is kept to press from both sides during heat treatment It keeps steady to reinforce and lean on, it is desirable that the fixture has the function of that plurality of specifications spherical shape sample is clamped, and to ensure in use not It deforms, there is good anti-oxidant and higher elastic limit.

Invention content

The fixture made by this method is capable of the spherical sample of stable holding different size, in subsequent heat treatment To application, it is ensured that practical application effect.

A kind of production method of multi-function ball clamp, includes the following steps：

（1）Select that two diameters are 30mm and length is the 60Si2Mn alloy spring steels of 1014mm as raw material；

（2）By one end of every alloy spring steel weld two pieces of diameters be 45mm and thickness be 5mm semicircular plate, two pieces Angle is 120 degree ~ 150 degree between semicircular plate, forms small jaw；

（3）It is the semi-circular arc of 50mm by alloy spring steel one radius of bending, forms mouth of tongs, be bent starting point distance At welded plate 314mm；Mouth of tongs is for being clamped the spherical sample that diameter is 50mm~150mm；

（4）A pin hole is bored in bending initial point position；

（5）By the pin hole of two alloy spring steels to just and with axis pin being hinged, keep two small jaws opposite；Two pieces of small jaws Between opening degree be 60 degree；Small jaw is for being clamped the spherical sample that diameter is 20mm~50mm；

（6）Heat treatment process：

I, annealing heating temperature is 750 DEG C, keeps the temperature 3 hours, is down to 500 DEG C with 50 DEG C of cooling velocities per hour and comes out of the stove；

II 850 DEG C of hardening heats, keeping the temperature 30 minutes carries out water cooling 10 seconds, then carries out oil and is cooled to room temperature；

III, tempering process is 480 DEG C of first time temperature, keeps the temperature oil cooling in 120 minutes, and second of temperature is 460 DEG C, oil cooling in 120 minutes is kept the temperature, hardness is HRC42 after double tempering.

The fixture that the present invention makes meets the heat treatment operation of all spherical test check projects in scene, by long-term real Trample use, work well, especially when making heat-treatment quenching operation, under quick agitation, can stable and firm clamping sample, Sample will not occur to fall or deform, to ensure that the tissue reached needed for sample, effectively increase working efficiency.

Specific implementation mode

Multi-function ball clamp is made of handle (a pair), mouth of tongs, small jaw and axis, and one end of handle is mouth of tongs, Mouth of tongs end is small jaw.
