Abstract
The invention discloses a heat treatment technique of a lock case die carrier. The outline of the lock case die carrier is in a cuboid structure. The heat treatment process comprises the steps of heating and holding, quenching and tempering. The quenching medium adopted by the quenching after the heating and holding is saline water with the concentration of 8-12%; and when the lock case die carrier enters the quenching medium, an inclination angle of greater than 45 degrees is kept between the lock case die carrier and the horizontal surface of the quenching medium. By using the saline water with the concentration of 8-12% as the quenching medium, bubbles, which are generated when the die carrier enters the quenching medium, can quickly rupture, thereby lowering the quenching soft spot, ensuring the same cooling rate of the upper and lower die surfaces, and further ensuring the quenching soft spot hardness of the upper and lower die surfaces. The lock case die carrier is put into the quenching medium at the inclination angle of greater than 45 degrees, so that the bubbles can rupture and flow away, thereby ensuring the quenching effect and ensuring the upper and lower die surfaces to be respectively within the hardness range.
Description
Technical field
The present invention relates to forge hot Application Areas, is a kind of thermal treatment process of lock housing mould bases specifically.
Background technology
Be generally foundry goods with the lock housing that locking bolt is supporting, change forging into because of customer demand afterwards, lock housing mould bases is then be lock housing forging special die carrier, and material adopts 45# steel, but in heat-treatment quenching process, easily occur that upper and lower mould surface hardness is uneven, causes quenching unsuccessfully.
Summary of the invention
The object of this invention is to provide a kind of thermal treatment process of lock housing mould bases, solve lock housing mould bases after heat-treatment quenching, easily occur that upper and lower mould surface hardness is uneven, cause failed problem of quenching
For achieving the above object, the technical solution adopted in the present invention is: a kind of thermal treatment process of lock housing mould bases, the outline of described lock housing mould bases is pane structure, its heat treatment process comprises heating and thermal insulation, quenching, tempering, the salt solution of the quenchant that quenching after heating and thermal insulation adopts to be concentration be 8%-12%.
When described lock housing mould bases enters quenchant, keep certain angle of inclination with the horizontal plane of quenchant.
Angle of inclination when described lock housing mould bases enters quenchant is greater than 45 °.
Beneficial effect of the present invention: adopt concentration to be that the salt solution of 8%-12% is as quenchant, the bubble rapid disruption that mould bases produces when entering quenchant can be made, thus decrease quenching soft spot, ensure that upper and lower die face speed of cooling is consistent, thus guarantee that upper and lower mould surface hardness is consistent; Lock housing mould bases puts into quenchant with the angle of inclination that is greater than 45 ° simultaneously, can bubbles burst be made further to flow away, thus ensures quenching effect, ensures that upper and lower die face is all in durometer level.
Embodiment
Below in conjunction with embodiment, the present invention is described in further detail:
The outline of described lock housing mould bases is pane structure, get 5 groups of lock housing mould bases put into vacuum oven respectively and be heated to 1130 DEG C of insulations 100 minutes, then shift out in stove, and put into mode with the angle of inclination of 45 °, put into the salt solution that concentration is 8%, 9%, 10%, 11%, 12% respectively, cooled rear tempering and measured the hardness of its upper and lower die face.
Concrete Hardness results value is as following table.
| Embodiment | Brine concentration (%) | Patrix hardness (HRC) | Counterdie hardness (HRC) |
| 1 | 8 | 61.1 | 60.2 |
| 2 | 9 | 60.8 | 59.8 |
| 3 | 10 | 60.2 | 60.3 |
| 4 | 11 | 60.2 | 59.6 |
| 5 | 12 | 60.5 | 60.1 |
Adopt concentration be the salt solution of 8%-12% as quenchant, the bubble rapid disruption that mould bases produces when entering quenchant can be made, thus decrease quenching soft spot, ensure that upper and lower die face speed of cooling is consistent, thus guarantee that upper and lower mould surface hardness is consistent; Lock housing mould bases puts into quenchant with the angle of inclination that is greater than 45 ° simultaneously, can bubbles burst be made further to flow away, thus ensures quenching effect, ensures that upper and lower die face is all in durometer level.
Claims (3)
1. the thermal treatment process of a lock housing mould bases, the outline of described lock housing mould bases is pane structure, its heat treatment process comprises heating and thermal insulation, quenching, tempering, it is characterized in that: the salt solution of the quenchant that quenching after heating and thermal insulation adopts to be concentration be 8%-12%.
2. the thermal treatment process of a kind of lock housing mould bases according to claim 1, is characterized in that: when described lock housing mould bases enters quenchant, keep certain angle of inclination with the horizontal plane of quenchant.
