Embodiment example 1

[0030] see Figure 1-6 , the present invention provides a technical solution: a quenching mold for the outer ring of a double-row spherical roller bearing made of large-size carburizing steel, including a box body 1, a quenching mechanism 2, and a spray connecting pipe 3, and the quenching mechanism 2 is arranged in the box On the top of the body 1, the spray connecting pipe 3 is arranged on the surface side of the box body 1 and connected with the quenching mechanism 2;

[0031] The inside of the box body 1 is provided with a driving mechanism 4, a cleaning device 5, and a cleaning device 6. The driving mechanism 4 is arranged at the top center of the inner wall of the box body 1, and the cleaning device 5 is arranged at the inner wall of the box body 1 and is located at the center. The cleaning device 6 is cooperatively connected to the bottom of the driving mechanism 4, and the bottom of the cleaning device 6 is connected with the impurity removal device 5, which can filter...

Embodiment example 2

[0033] The impurity removal device 5 is provided with a support ring 51, a conical filter screen 52, an arc-shaped elastic member 53, an arc surface protrusion 54, and a high-frequency elastic member device 55. The support ring 51 is arranged on the inside of the casing 1, and the conical filter screen The top edge of 52 is fixedly connected with the inner wall of the support ring 51, the arc elastic member 53 is fixed between the bottom of the support ring 51 and the corresponding two sides of the inner wall of the box body 1, and the arc protrusion 54 is fixed on the top of the support ring 51, The high-frequency elastic device 55 is arranged on the surface bottom of the conical filter screen 52. When the spray water in the quenching mechanism 2 falls on the conical filter screen 52, impurities such as debris and dust can be filtered out in time, and the drive The mechanism 4 drives the cleaning device 6 to clean up the filtered impurities in time, and under the elastic force...

Embodiment example 3

[0036] The cleaning device 6 is provided with a rotating shaft 61, a brushing device 62, and a pressing ball 63. The top of the rotating shaft 61 is connected with the drive mechanism 4. The brushing device 62 is fixed on the surface bottom of the rotating shaft 61, and the pressing ball 63 is fixed on the brushing device. 62 away from the end of the rotating shaft 61, when the rotating shaft 61 rotates under the drive of the driving mechanism 4, the brushing device 62 will rotate on the surface of the conical filter screen 52, and the filtered impurities will be quickly cleaned to avoid the accumulation of impurities , there will be no blockage, and the pressing ball 63 will also be driven to rotate at the same time, and then the support ring 51 and the conical filter screen 52 will be pressed downward through the arc surface protrusion 54, so that the conical filter screen 52 will shake up and down, and then Helps shake out impurities with vibration.

Abstract

The invention discloses a large-size carburizing steel double-row self-aligning roller bearing outer ring quenching mold which comprises a box body, a quenching mechanism and a spraying connecting pipe, the quenching mechanism is arranged at the top of the box body, and the spraying connecting pipe is arranged on one side of the surface of the box body and is connected with the quenching mechanism in a matched mode; a driving mechanism, an impurity removing device and a cleaning device are arranged in the box body, the driving mechanism is arranged in the center of the top of the inner wall of the box body, the impurity removing device is arranged on the inner wall of the box body and located in the center, and the cleaning device is connected to the bottom of the driving mechanism in a matched mode; the bottom of the cleaning device is connected with the impurity removing device in a matched mode. The large-size carburizing steel double-row self-aligning roller bearing outer ring quenching mold achieves the purpose of filtering and deslagging, can filter water in time, reduces the influence of impurities, ensures the quenching quality, can perform anti-blocking, and improves the use performance.

Description

technical field [0001] The invention relates to the technical field of heat treatment, in particular to a quenching die for the outer ring of a double-row spherical roller bearing made of large-size carburizing steel. Background technique [0002] With the rapid development of industry, more and more bearings are used. Carburized steel has superior comprehensive performance and is suitable for manufacturing large double row spherical roller bearings. There are two rows of spherical rollers, and the outer ring has a common spherical raceway, which has good self-aligning performance. When the shaft is bent by force or the installation is not concentric, the bearing can still be used normally. This type of bearing has a large load capacity. Except Can bear radial load The outer bearing can also bear the axial load acting in both directions, and has good impact resistance. Generally speaking, the allowable working speed of spherical roller bearings is low. Generally, the outer...
