Abstract
The utility model relates to a novel forming cooling device of a spline housing. The novel forming cooling device of the spline housing comprises a cooling water tank body, wherein a cooling water pipe is arranged on the cooling water tank body, a water outlet is formed in the cooling water tank body, the distance between the water outlet and the bottom of the tank body is D, and the distance between the water outlet and the bottom of the tank body is matched with the length of a blank with a local part to be heated. Compared with the prior art, the novel forming cooling device of the spline housing has the advantages that underfill and high flash are avoided in a forge-forming process and the defect that the underfill and high flash can occur frequently in a forge-forming process in the prior art is overcome.
Description
Technical field
The utility model relates to heavy spline housing field, is mainly a kind of moulding cooling device of novel spline housing.
Background technology
In existing FMT, various about the technique that heavy spline housing forges, modal have cold-extruded and a forge hot; Forge hot is divided into horizontal forging and upsetting machine forging and jumbo such as 4000T hot forging and forges, what I said is the cover class that our company adopts jumbo (4000T hot forging moulding), the former traditional handicraft of our company forges in process and occurs that (the misrun position is random to misrun, show the A place as Fig. 1), while head overlap high (B place).Traditional forging mode is for participating in the part intermediate frequency heating to 1050 that is out of shape～1200 degree local heat, rear 4000T hot forging moulding.
The utility model content
The purpose of this utility model is to overcome the deficiency that prior art exists, and a kind of moulding cooling device of novel spline housing is provided, and a kind ofly can make heavy spline housing in forging process, does not produce misrun and prevents the high device of major part end overlap.
The purpose of this utility model is completed by following technical solution, the moulding cooling device of this novel spline housing, comprise the cooling water casing, be provided with cooling water pipe on described cooling water casing, have on the cooling water casing apart from the bottom half distance and be the delivery port of D, this distance matches with the charge length of local heat.
The blank of described local heat is the part of 30～40mm for close blank head length.
The beneficial effects of the utility model are: with traditional comparing, the utility model in forging molding without misrun with prevented the high generation of head overlap.Misrun and the high 2 kinds of defects of head overlap of having avoided forging molding often to have.
Description of drawings
Fig. 1 is misrun position and the head overlap high-order bit schematic diagram after former moulding process moulding;
Fig. 2 is the cooling device of ready-made type technique.
Wherein: cooling water pipe 1; Blank 2; Cooling water casing 3; Delivery port 4.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is done detailed introduction:
As shown in Figure 2, the moulding cooling device of this novel spline housing, comprise cooling water casing 3, being provided with cooling water pipe 1(on described cooling water casing 3 substitutes with the plastic water pipe of diameter 6～12mm), have on cooling water casing 3 apart from the bottom half distance and be the delivery port 4 of D, this distance matches with blank 2 length of local heat, and the blank of described local heat is the part of 30～40mm for close blank head length.
The moulding process of this novel spline housing described in the utility model, be a kind ofly by 4000T hot forging equipment, to make heavy spline housing not produce misrun, prevents simultaneously a kind of technique that the head overlap is high.First the length of being out of shape part heating-up temperature local heat with 1050～1200 degree in intermediate frequency furnace will be participated in blank; Then with cooling water, the blank of local heat partly is cooled to 700～850 degree in the cooling water casing, water temperature is normal temperature, and be 10～50S cool time; Forge finally.
Operation principle: the blank after heating is put in the cooling water casing, there is cooling water to flow in cooling water pipe, it is the delivery port of 30mm that a diameter is arranged in the cooling water casing, and the inner bottom surface of the dried up case of delivery port is 30～40mm approximately, guarantees the water-immersed size of local header; Water flows into from cooling water pipe, the delivery port from the cooling water casing flows out, and has formed circulation, makes water temperature under the normal temperature state.Be cooled to 700～850 degree in cooling water, water temperature is normal temperature, and be 10～50S cool time; Rear 4000T moulding, successful solution misrun and the large quality problems of overlap high two of heavy spline housing.Apply in other heavy spline housing simultaneously.
The utility model is not limited to above-mentioned embodiment; no matter do any variation on its shape or material formation; every employing structural design provided by the utility model, be all a kind of distortion of the present utility model, all should think within the utility model protection domain.
Claims (2)
1. the moulding cooling device of a novel spline housing, comprise the cooling water casing, it is characterized in that: be provided with cooling water pipe on described cooling water casing, have on the cooling water casing apart from the bottom half distance and be the delivery port of D, this distance matches with the charge length of local heat.
2. the moulding cooling device of novel spline housing according to claim 1 is characterized in that: the blank of described local heat is for being the part of 30～40mm near blank head length.
