Description

Heat treatment suspension bracket

Technical field

The utility model relates to Field of Heat-treatment, particularly relates to a kind of heat treatment suspension bracket.

Background technology

Heat treatment refers to metal material in the solid state, by the means of heating, insulation and cooling, changes material surface or interior The chemical composition in portion and tissue, it is thus achieved that a kind of metal fever processing technology of desired properties.

For conventional heat treatment, workpiece to be heated is often stacked to be put in heat treatment heating furnace, phase between workpiece Contact mutually, the part contacting with each other causes mutually blocks, and the part that workpiece is blocked often makes inside and outside workpiece temperature uneven Even, affect thermal treatment quality, and for some special-shaped workpieces, be packed together heat treatment, mutually extrude between workpiece, can cause Workpiece deforms；For thermo-chemical treatment, need typically also not allow to contact with each other between workpiece working surface to be processed, it is to avoid work Part surface to be heated is blocked by other workpiece and is caused and affect thermo-chemical treatment quality.

It in order to disposable thermal processes multiple workpiece in prior art, is generally all to be placed on batches of workpiece on suspension bracket, It is placed into the workpiece on whole suspension bracket and suspension bracket in heat-treatment furnace.And conventional modes of emplacement is all to stack workpiece or bundle Prick on support, contact with each other between workpiece, block, affect thermal treatment quality.

Utility model content

The utility model is intended to provide a kind of heat treatment suspension bracket, to avoid between workpiece during heat treatment mutually Contact, affects thermal treatment quality.

Heat treatment suspension bracket in this programme, including bearing bar, bearing bar is provided with two annulus being parallel to each other, load-bearing Bar is placed in two annulus, and bearing bar is connected fixing with annulus by pole；It is fixed with some montants, montant between two annulus Parallel with bearing bar, bearing bar is provided with some bracers, and a bracer is in spiral distribution and is fixed on bearing bar, every piece of support Block, both facing to a montant, montant is just fixed with block to the position of a bracer, and bearing bar top is provided with hanger.

The two ends of workpiece are respectively placed on a bracer and corresponding montant by the know-why of this programme and having the beneficial effect that Block on, owing to the block on montant is corresponding with bracer, and just to a bracer, therefore workpiece is disposed horizontally in often On a pair corresponding block and a bracer, again owing to a bracer Spiral distribution is on bearing bar, therefore workpiece is also around bearing bar Spiral distribution is between bearing bar and montant, so mutually staggering between workpiece, will not contact with each other between workpiece, it is ensured that The thermal treatment quality of each workpiece, and workpiece in spiral distribution than overlap the to each other distribution be more beneficial for heat workpiece it Between circulation, be more beneficial for the heating of workpiece.When needs carrying suspension bracket, sling hanging on bearing bar by suspenders such as conventional door machines Workpiece on whole suspension bracket and suspension bracket can be sling by ear, is hoisted in heat-treatment furnace i.e. thermally processable.

Prioritization scheme one based on such scheme: the size of described block and described bracer be not more than 10mm × 10mm × 10mm.Avoid block and excessive cause workpiece of bracer to block, and then avoid block to affect the quality of heat treatment of workpiece.

Prioritization scheme two based on prioritization scheme one: described in adjacent two, the vertical distance between a bracer is not less than 10cm.Avoid between workpiece excessively crowded, decrease heat and flow between workpiece, the efficiency of impact heat treatment.

Prioritization scheme three based on prioritization scheme two: the center of circle of described annulus is positioned on the axis of described bearing bar.Make The distance of annulus distance bearing bar is equal, thus also makes montant equal with the distance of bearing bar, is beneficial to put workpiece equably It is placed in suspension bracket.

Prioritization scheme four based on prioritization scheme three: be evenly equipped with some through holes on described annulus.Through hole is for interting lifting Steel wire rope, and then increase lifting suspension bracket when stress point, stress point is more, and the safety coefficient of handling is higher.

Brief description

Fig. 1 is the structural representation of the utility model embodiment heat treatment suspension bracket.

Detailed description of the invention

Below by detailed description of the invention, the utility model is described in further detail:

Reference in Figure of description includes: the 3rd, bearing bar the 1st, annulus the 2nd, pole is propped up bracer the 4th, block the 5th, montant and the 6th, hung Ear the 7th, workpiece 8.

Embodiment heat treatment suspension bracket is substantially as shown in Figure 1: include bearing bar 1, bearing bar 1 be provided with two mutually flat The annulus 2 of row, each annulus 2 is evenly equipped with four through holes, and the dead in line of the center of circle of annulus 2 and bearing bar 1, bearing bar 1 is put In annulus 2, bearing bar 1 is connected fixing with annulus 2 by pole 3；It is fixed with some montants 6, montant 6 between two annulus 2 Parallel with bearing bar 1, bearing bar 1 is provided with some bracers 4, and the vertical distance between two bracers 4 is 15cm, a bracer 4 is in spiral distribution and be fixed on bearing bar 1, and every piece bracer 4 is both facing to a montant 6, just to a bracer 4 on montant 6 Position is fixed with block 5, and bearing bar 1 top is provided with hanger 7, the size of block 5 and a bracer 4 be 10mm × 10mm × 10mm。

The two ends of workpiece 8 are respectively placed on the block 5 on a bracer 4 and corresponding montant 6, due to the gear on montant 6 Block 5 and bracer 4 are to corresponding, and just to a bracer 4, every a pair corresponding block 5 and a bracer 4 are contour, therefore workpiece 8 quilt It is disposed horizontally on every a pair corresponding block 5 and a bracer 4, again owing to bracer 4 Spiral distribution is on bearing bar 1, Therefore workpiece 8 also around bearing bar 1 Spiral distribution between bearing bar 1 and montant 6, so mutually staggering between workpiece 8, workpiece 8 Between will not contact with each other, it is ensured that the thermal treatment quality of each workpiece 8, and workpiece 8 ratio in spiral distribution phase mutual respect It is distributed foldedly and is more beneficial for heat and circulates between workpiece 8, be more beneficial for the heating of workpiece 8.When needs carrying suspension bracket, with often The suspender such as door machine sling the hanger 7 on bearing bar 1, the workpiece 8 on whole suspension bracket and suspension bracket can be sling, be hoisted to heat Process in stove i.e. thermally processable.

The size of block 5 and a bracer 4 is 10mm × 10mm × 10mm, it is to avoid block 5 and a bracer 4 are excessive to workpiece 8 cause and block, and then avoid block 5 to affect the quality of heat treatment of workpiece 8, further ensure the thermal treatment quality of workpiece 8. Distance between two adjacent supports blocks 4 is 15cm simultaneously, it is to avoid excessively crowded between workpiece 8, decrease heat workpiece 8 it Between flowing, impact heat treatment efficiency.Through hole on annulus 2, for interting the steel wire rope lifting by crane, increases when lifting by crane suspension bracket Stress point, improves safety coefficient during handling.

Above-described is only embodiment of the present utility model, and in scheme, the general knowledge such as known concrete structure and characteristic is at this Too much describe.It should be pointed out that, for a person skilled in the art, in the premise without departing from the utility model structure Under, some deformation can also be made and improve, these also should be considered as protection domain of the present utility model, and these are all without impact The effect of the utility model enforcement and practical applicability.The protection domain that this application claims should be with the content of its claim Being as the criterion, the detailed description of the invention in specification etc. records the content that may be used for explaining claim.
