Abstract
The utility model relates to an ultra-long track surface quenching device, belonging to an auxiliary device for ultra-long track surface quenching. The utility model provides the ultra-long track surface quenching device which has the advantages that the long track surface quenching treatment can be conducted at one step, the quality is ensured to be good and the production efficiency is high. The ultra-long track surface quenching device comprises a base and is structurally characterized in that a groove-shaped track is fixed above the base, baffles are respectively arranged at the front end and the rear end of the groove-shaped track, a support with wheels at the bottom is arranged in the groove-shaped track and the upper surface of the support is a flat surface.
Description
Technical field:
The utility model is to belong to a kind of supplementary unit that the overlength raceway surface quenches.
Background technology:
Multifunction crane is the key equipment of large-sized prebaked Aluminium Electrolysis, by cart, instrument dolly, go out aluminium dolly, pneumatic system etc. and partly form.The cart wheel adopts no wheel rim vertical wheel to add the form of horizontal wheel guiding, travels on overhead crane orbit.In practical work process, wheel excircle (tread) contacts with track, and track bears than large period load and intensive rolling resistance wearing and tearing.The contact surface of track and wheel such as hardness inequality will cause occurring impression or pit, produce wearing and tearing early in the part, and shortened the work-ing life of track.Therefore, after raceway surface quenches, must have enough hardness (40～45HRC), the important requirement Hardness Distribution is necessarily even, on whole track, can not exist soft band, soft spots etc. (≤8.5m), depth of hardening zone is at 3～5mm.Adopt the method for surface induction hardening to realize by technical requirements.
Stroke characteristics at intermediate frequency table quenching lathe, its range is 2m, can't disposablely finish the table of one≤8.5m and quench when track is carried out surface induction hardening, needs to divide to carry out several times, the joining place of quenching at each table has the soft band of a 20～30mm, and this is the quench shortcoming of technology of table; Can not be overlapping when twice table quenched, overlapping back just will crack.In order to prevent that crackle from occurring, and on the track of one≤8.5m, just has 3 soft bands.The length overall of overhead crane orbit is mostly at 23～25m, is spliced by the track of 3 sections≤8.5m, will have 9 soft bands to exist, and production efficiency is low, the cycle is long, inner quality is low, school shape difficulty, and the wear resistance and the work-ing life of track descend greatly.
Summary of the invention:
The utility model is exactly at the problems referred to above, and providing a kind of can once carry out the device that the overlength raceway surface quenching that quality is good, production efficiency is high was handled, guaranteed in hard surfacing to long track.
For achieving the above object, the utility model adopts following technical scheme, and the utility model comprises base, and the upper fixed of its structural feature base has channel suspending rail, and front end, the rear end of channel suspending rail are respectively arranged with baffle plate; Be provided with the bearing that the bottom has wheel in the channel suspending rail, the upper surface of bearing is the plane.
The utility model beneficial effect:
Because the upper fixed of the utility model base has channel suspending rail, front end, the rear end of channel suspending rail are respectively arranged with baffle plate; Be provided with the bearing that the bottom has wheel in the channel suspending rail, the upper surface of bearing is the plane; In use, will be placed on the upper surface of bearing by the long track that hard surfacing is handled, the operator at the uniform velocity promotes track, makes bearing along at the uniform velocity mobile in the channel suspending rail, finishes the quench treatment of workpiece raceway surface.
The utility model can be suitable for the hard surfacing of slender pieces such as various side's rails, I-rail to be handled.
The utility model has increased existing quenching machine use range, has not only guaranteed the quenching quality, and has improved production efficiency.
Description of drawings:
Below in conjunction with the drawings and specific embodiments the utility model is described further.
Fig. 1 is the utility model structural representation.
Embodiment:
As shown in Figure 1, the utility model comprises base 1, and the upper fixed of base 1 has channel suspending rail 3, and the front end of channel suspending rail 3, rear end are respectively arranged with baffle plate 2; Be provided with the bearing 4 that the bottom has wheel 5 in the channel suspending rail 3, the upper surface of bearing 4 is the plane.
During use, will be placed by the long track 6 that hard surfacing is handled on the upper surface of bearing 4, the operator at the uniform velocity promotes long track 6, makes bearing 4 along at the uniform velocity mobile in the channel suspending rail 3, finishes the quench treatment on long track 6 surfaces.
