Description
Technical field
The utility model is related to arrive heat treatment accessory application field, the utility model discloses a kind of I-shaped baffle combinations
Formula charging tray.
Background technology
In bearing industry, using advanced protective atmosphere roller bottom stove salt hardening heat-treatment production line, the whole of bearing parts is realized
Body heat processing；The integral level of the thermal treatment quality of bearing parts is compared than before at present, is had and is significantly promoted.Directly
Big specification GCr15SiMn bearing spherical surfaces roller, conical bearing roller and the cylindrical bearing roller etc. of diameter not less than 50mm it is large-scale and
For extra large size bearing roller when this production line quench tempering, finding individual rollers, there are points hardness to be less than standard value 1HRC
The problem of~5HRC, has a very large relationship through analysis and the charge mode of roller.It is well known that the charging tray of roller hearth furnace production line
It is by the rotation of roller stick, in different stations such as the preceding cleaning of its production line, Quench heating, medium cooling, rear cleaning, tempering
Realize its linear movement.During putting for clearance-type is presented in the large roller for entering stokehold in charging tray, but charging tray moves integrally,
Due to unobstructed, roller therein can not inevitably generate movement so that rolling surface, end face unavoidably generate and connect between roller
It touches, when roller heats and quenches cooling, contact site is generated generates troostite group because underheat and inhomogeneous cooling are even
It knits, to the relatively low problem of roller points hardness occur.In order to solve the relatively low quality problems of big specification roller hardness, meet big
The Multiple Type roller of specification carries out the technological requirement of marquench and the compound quenching of horse shellfish in same equipment, ensures
The roller thermal treatment quality requirements of large scale specification, improve the case hardness of roller and the uniformity of hardness, need to use
A kind of new roller charging tray, it is existing because bearing roller heats uneven and cooling uneven, bearing caused by expiring to solve
After roller quenching the problem of lower hardness.
Invention content
In order to solve the problems, such as background technology, the utility model proposes a kind of I-shaped partition board assembling type charging tray,
It is hard after bearing roller quenches caused by heating is uneven and inhomogeneous cooling is even in existing bearing roller heat treatment process for solving
Spend relatively low problem.
The purpose of this utility model adopts the following technical scheme that realize：
A kind of I-shaped partition board assembling type charging tray, including frame, spacer screen, vertical clapboard and diaphragm plate are constituted；The frame
It is arranged in surrounding, spacer screen is arranged in the bottom surface of frame, and diaphragm plate horizontal homogeneous is arranged in frame the top of spacer screen, and vertical clapboard hangs down
Directly it is uniformly arranged on the top of diaphragm plate and is connect with diaphragm plate；The diaphragm plate is I-shape construction, the middle part of diaphragm plate
For strip rectangular clapboard, partition board both ends are symmetrically arranged with the positioning plate with divider upright, and positioning plate is billet shape rectangular slab, fixed
The intermediate inside of position plate is connect with strip rectangular clapboard, and positioning plate thickness is consistent with strip rectangular clapboard, between diaphragm plate
It is arranged in parallel.
The vertical clapboard is identical as diaphragm structure, is arranged in parallel between vertical clapboard, the spacing between vertical clapboard and cross
Spacing between partition board is adjustable.
The square frame that the frame is surrounded by elongated plates, frame medial surface and the end of diaphragm plate, vertical clapboard are equal
Keep gap.
The spacer screen is the silk screen of diamond-shaped meshes structure, and the size of spacer screen is consistent with the bottom face profile size of frame, bottom
The size of net mesh is less than the diameter dimension for the bearing roller placed, and the upper surface of spacer screen periphery is connect with frame bottom surface.
The utility model uses above technical scheme, achieves good effect：I-shaped partition board assembling type charging tray, can have
The isolation bearing roller of effect, avoid because bearing roller contact with each other the underheat of generation, inhomogeneous cooling it is even and caused by quench
The problem of hardness afterwards reduces, improves the quality of bearing roller, and the total quality of bearing and service life is made to be improved.
Description of the drawings
Fig. 1 is the vertical view of the utility model.
Fig. 2 is the upward view of the utility model.
In figure：1, frame, 2, diaphragm plate, 3, vertical clapboard, 4, spacer screen, 5, bearing roller.
Specific implementation mode
The utility model specific embodiment is described with reference to the drawings：
Such as a kind of Fig. 1 I-shaped partition board assembling type charging trays shown in Fig. 2, including frame 1, spacer screen 4, vertical clapboard 3 and tabula 4
Plate is constituted；The square frame surrounded by elongated plates in surrounding, frame 1 is arranged in the frame 1；The setting of spacer screen 4 exists
The bottom surface of frame 1, spacer screen 4 are the silk screen of diamond-shaped meshes structure, and the size of spacer screen 4 is consistent with the bottom face profile size of frame 1, bottom
The size of 4 mesh of net is less than the diameter dimension for the bearing roller 5 placed, and the upper surface of spacer screen 4 periphery is connect with 1 bottom surface of frame；Institute
The top of the spacer screen 4 in frame 1 is arranged in 2 horizontal homogeneous of diaphragm plate stated, and diaphragm plate 2 is I-shape construction, the middle part of diaphragm plate 2
For strip rectangular clapboard, partition board both ends are symmetrically arranged with the positioning plate with divider upright, and positioning plate is billet shape rectangular slab, fixed
The intermediate inside of position plate is connect with strip rectangular clapboard, and positioning plate thickness is consistent with strip rectangular clapboard, between diaphragm plate 2
It is arranged in parallel；The vertical clapboard 3 is vertical uniform to be arranged on the top of diaphragm plate 2 and is connect with diaphragm plate 2, vertical clapboard 3 and cross
2 structure of partition board is identical, is arranged in parallel between vertical clapboard 3, and the spacing between the spacing between vertical clapboard 3 and diaphragm plate 2 is adjustable, horizontal
The end of partition board 2 and vertical clapboard 3 keeps gap with 1 inside of frame.
Before bearing roller enters roller hearth furnace production line, bearing roller 5 is placed into " I " fonts combined type charging tray first
Diaphragm plate 2 and the checked spun antung that constitutes of vertical clapboard 3 in, after all piling bearing roller in checked spun antung, filling bearing roller 5
Charging tray is placed on the roller of protective atmosphere roller bottom stove feeding station, the charging process of roller is completed, then according to technological process：
Feeding → preceding cleaning → heating → salt hardening → air-cooled → postcooling → tempering → air-cooled → cleaning → discharging, to complete matched bearings
Heat treatment process of the roller in roller hearth furnace production line.
