Abstract
The utility model discloses a take large -scale rectangle die holder structure of prestressing force blank pressing, it includes die holder owner frame and bottom plate, wherein, die holder owner frame is fixed in on the bottom plate, the extending all around of terminal surface of bottom plate has the prestressing force limit, the cooperation the prestressing force limit in the fixed slot has been seted up all around to the bottom of die holder owner frame, the fixed slot of die holder owner frame set up in prestressing force edge and the mode through the hot jacket are fixed in on the bottom plate. Above -mentioned take large -scale rectangle die holder structure of prestressing force blank pressing adopts the split type structure of compriseing bottom plate and die holder owner frame, and is provided with the prestressing force limit on the bottom plate. Not only simple structure, greatly reduced the manufacturing degree of difficulty and manufacturing cost, and increased the stress limit and improved the bearing strength of die holder, improved the stress of die holder and eliminated the stress concentration that whole die holder inner chamber base angle produced the fracture easily regionally.
Description
Technical field
This utility model relates to a kind of die holder structure, particularly relates to the large-scale rectangular die holder structure of a kind of band prestressing force flanging.
Background technology
At present, the existing large-scale rectangular die holder structure for fly press forging all uses overall structure.Owing to die holder structure is big, though using overall construction intensity rigidity good, but structure is complicated, manufacture difficulty large period is long, and cost is high, and easily produces stress concentration at overall die holder cavity bottom fillet, and production is produced a very large impact by the most cracking meeting.
Utility model content
The purpose of this utility model is to provide the large-scale rectangular die holder structure of a kind of band prestressing force flanging, and it has simple in construction, low cost and the feature of length in service life, to solve the problems referred to above that prior art medium-and-large-sized rectangle die holder exists.
For reaching this purpose, this utility model by the following technical solutions:
A kind of large-scale rectangular die holder structure of band prestressing force flanging, it includes the main frame of die holder and base plate, and wherein, the main frame of described die holder is fixed on described base plate, the end face of described base plate extended around prestressing force limit.
Especially, described in described prestressing force edge, the end face surrounding of base plate upwardly extends, coordinating described prestressing force limit to offer fixing groove in the bottom surrounding of the main frame of described die holder, the fixing groove of the main frame of described die holder is arranged on described prestressing force limit and by the way of hot jacket and is fixed on described base plate.
The beneficial effects of the utility model are, the large-scale rectangular die holder structure of the most described band prestressing force flanging uses the split-type structural being made up of the main frame of base plate and die holder, and is provided with prestressing force limit on base plate, has the advantage that
1) base plate adds the bearing strength of stress limit raising die holder；
2) improve the stress of die holder and eliminate region of stress concentration；
3) greatly reduce manufacture difficulty and manufacturing cost, through actually used, there is the highest techno-economic effect.

In figure:
1, the main frame of die holder；2, base plate；3, prestressing force limit；4, fixing groove.
Detailed description of the invention
Further illustrate the technical solution of the utility model below in conjunction with the accompanying drawings and by detailed description of the invention.
Referring to shown in Fig. 1, Fig. 1 is the structural representation of the large-scale rectangular die holder structure of the band prestressing force flanging that this utility model detailed description of the invention 1 provides.
In the present embodiment, the large-scale rectangular die holder structure of a kind of band prestressing force flanging includes that the main frame of die holder 1 and base plate 2, the main frame of described die holder 1 are fixed on described base plate 2, and the surrounding of the end face of described base plate 2 has upwardly extended prestressing force limit 3.Coordinating described prestressing force limit 3 to offer fixing groove 4 in the bottom surrounding of the main frame of described die holder 1, the fixing groove 4 of the main frame of described die holder 1 is arranged on described prestressing force limit 3 and by the way of hot jacket and is fixed on described base plate 2.
During installation, described base plate 2 is heated to uniform temperature frame 1 main with the die holder of cold conditions and is connected, and after cooling, band base plate 2 frame main to die holder 1 produces the biggest compressive stress.
Above example simply elaborates ultimate principle of the present utility model and characteristic; this utility model is not limited by above-mentioned example; on the premise of without departing from this utility model spirit and scope; this utility model also has various change and change, in the range of these changes and change both fall within claimed this utility model.This utility model claims scope and is defined by appending claims and equivalent thereof.
Claims (2)
1. the large-scale rectangular die holder structure of a band prestressing force flanging, it is characterised in that it includes the main frame of die holder and base plate, and wherein, the main frame of described die holder is fixed on described base plate, the end face of described base plate extended around prestressing force limit.
The large-scale rectangular die holder structure of band prestressing force flanging the most according to claim 1, it is characterized in that, described in described prestressing force edge, the end face surrounding of base plate upwardly extends, coordinating described prestressing force limit to offer fixing groove in the bottom surrounding of the main frame of described die holder, the fixing groove of the main frame of described die holder is arranged on described prestressing force limit and by the way of hot jacket and is fixed on described base plate.
