Abstract
The utility model provides a furnace charging tool for performing the ion nitridation to a whole gear, which has the following specific structure: a tube type stand column (1) is vertically connected with a chassis (5) in a welding way; a large circular hole is arranged in the middle of a circular pergola clapboard (4), and a tapered support pillar (3) is vertically welded on a ring belt of the circular pergola clapboard (4) by three points equilaterally at 120 degrees; a welding piece of the tube type column (1) and the chassis (5) and the tube type column (1) are upwards arranged on a cathode disc, a welding piece of the tapered support pillar (3) and the circular pergola clapboard (4) is arranged on the chassis (5), and the large circular hole of the circular pergola clapboard (4) is sheathed on the tube type stand column (1); and a gear workpiece 2 is arranged at the upper end of the tapered support pillar (3). The gear is wholly nitrided by the tool, so that the nitridation area on the surface of the gear workpiece is greatly enlarged, the end face at the middle umbilical region of the gear is nitrided, the whole gear is attractive, and the corrosion resistance and the rust resistance are greatly improved.
Description
Technical field
The utility model relates to gear thermal treatment frock, is specifically related to the whole ion nitriding shove charge of a kind of gear frock.
Background technology
Ion nitriding is for its charging mode, be that frock has extremely strict requirement, characteristics because of ion nitriding, the contact site of gear and gear, gear and frock all can not nitrogenize because of shielding, still keep its original metalluster, do not have the nitrogenize part surface promptly not have hardness not corrosion-resistant yet, naked in the middle of air oxidation and rusting very easily, especially gear umbilical region end face oxidation and rusting is obvious.
Summary of the invention
The purpose of this utility model provides a kind of whole ion nitriding shove charge of gear frock that can be used for the gear bulk treatment.
The tubular type column (1) and vertical being welded to connect in chassis (5) of the whole ion nitriding shove charge of the utility model gear frock have big hole in the middle of the taper fore-set (3) and vertical being welded to connect of circular flower stand dividing plate (4), circular flower stand dividing plate (4); Tubular type column (1) and chassis (5) weldment tubular type column (1) upwards are placed on the cathode disc, put taper fore-set (3) and circular flower stand dividing plate (4) weldment on chassis (5), and the big hole of circular flower stand dividing plate (4) is enclosed within on the tubular type column 1.
Described taper fore-set (3) is divided equally 3 vertical welding by 120 degree on circular flower stand dividing plate (4) endless belt.
The tapered head in two ends of described taper fore-set (3).
Described conical head circular diameter is 3mm-6mm.
The whole ion nitriding shove charge of the utility model gear frock, by using it to the whole nitrogenize of gear, gear workpiece surface nitrogenize area significantly increases, and especially the umbilical region end face all obtains nitrogenize in the middle of the gear, make the gear overall appearance, corrosion-resistant antirust ability obviously improves.
Description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is the whole ion nitriding shove charge of gear tool structure figure.
Among the figure: tubular type column 1, workpiece gear 2, taper fore-set 3, circular flower stand dividing plate 4, chassis 5.
Embodiment
As shown in Figure 1, the whole ion nitriding shove charge of the utility model gear frock is made of tubular type column 1, taper fore-set 3, circular flower stand dividing plate 4 and chassis 5.Tubular type column 1 and chassis 5 vertical being welded to connect have requirement to verticality; Circular flower stand dividing plate 4 is annular steel plates of thick 5mm-8m, and the centre has big hole, divides equally 3 points by 120 degree on endless belt, in taper fore-set 3 and the circular flower stand dividing plate 4 vertical welding of respectively naming a person for a particular job.Taper fore-set 3 and circular flower stand dividing plate 4 welding, it is unshowy that the bright spot that retains on former as far as possible becomes, reduce to produce the degree of iron mold, during 3 welding of taper fore-set, guarantee the planeness of three end faces and following three end faces, make the workpiece gear 2 that is placed on it under hot state, still keep horizontal positioned and indeformable.Conehead shape is made at the two ends of taper fore-set 3, and is little with workpiece gear 2 contacts area like this, guarantees that the area of workpiece nitrogenize is enough big; Taper fore-set 3 conehead circular diameter are defined as 3mm-6mm according to the size and the weight of gear;
The length of taper fore-set 3 is also very important, if length is short, workpiece gear 2 spacings are little, is difficult for heat radiation, causes workpiece local temperature height, influences the product inner quality; If length is long, workpiece gear 2 spacings are big, and one to mount workpiece gear 2 numbers few, reduce production efficiency.
The auxiliary relevant equipment of the whole ion nitriding shove charge of gear frock comprises the cathode disc that carries workpiece, thermometric thermopair, the anode cap of water-cooled.Also comprise ammonia, acetone, power supply system and vacuum acquiring system.
The big bavin Germany Dao Yici of one vapour gear reaches the whole nitrogenize purpose of gear substantially by the whole ion nitriding shove charge of gear frock shove charge nitrogenize, has satisfied the requirement of the big bavin Germany Dao Yici of vapour gear technique, realizes quality product " German quality, European standard "
Claims (4)
1. the whole ion nitriding shove charge of a gear frock be is characterized in that: described tubular type column (1) and vertical being welded to connect in chassis (5) by tubular type column (1), taper fore-set (3), circular flower stand dividing plate (4) and chassis (5) formation; Described taper fore-set (3) and vertical being welded to connect of circular flower stand dividing plate (4); Have big hole in the middle of the described circular flower stand dividing plate (4); Described tubular type column (1) and chassis (5) weldment tubular type column (1) upwards are placed on the cathode disc, put taper fore-set (3) and circular flower stand dividing plate (4) weldment on chassis (5), and the big hole of circular flower stand dividing plate (4) is enclosed within on the tubular type column 1.
2. according to the whole ion nitriding shove charge of the described gear of claim 1 frock, it is characterized in that: described taper fore-set (3) is divided equally 3 vertical welding by 120 degree on circular flower stand dividing plate (4) endless belt.
