Abstract
The invention discloses a kind of large-scale rectangular die holder structures with prestressing force flanging, it includes the main frame of die holder and bottom plate, wherein, the main frame of die holder is fixed on the bottom plate, the end face of the bottom plate has extended around prestressing force side, the prestressing force side is coordinated to offer fixing groove in the bottom surrounding of the main frame of the die holder, the fixing groove of the main frame of die holder is set on the prestressing force side and is fixed on the bottom plate by way of hot jacket.The above-mentioned large-scale rectangular die holder structure with prestressing force flanging uses the split structure being made of bottom plate and the main frame of die holder, and prestressing force side is provided on bottom plate.It is not only simple in structure, greatly reduces manufacture difficulty and manufacturing cost；And it increases stress side and improves the bearing strength of die holder, improves the stress of die holder and eliminate the region of stress concentration that whole die holder inner cavity base angle easy tos produce cracking.
Description
Technical field
The present invention relates to a kind of die holder structure more particularly to a kind of large-scale rectangular die holder structures with prestressing force flanging.
Background technology
Currently, the existing large-scale rectangular die holder structure for fly press forging all uses overall structure.Due to mould
Holder structure is big, though it is rigid good using overall construction intensity, it is complicated, manufacture difficulty large period is long, it is of high cost, and in entirety
Stress concentration is easy tod produce at die holder cavity bottom fillet, once cracking can be to producing a very large impact.
Invention content
The purpose of the present invention is to provide a kind of large-scale rectangular die holder structures with prestressing force flanging, with structure letter
Feature single, at low cost and with long service life, to solve the above problem existing for large-scale rectangular die holder in the prior art.
For this purpose, the present invention uses following technical scheme：
A kind of large-scale rectangular die holder structure with prestressing force flanging comprising the main frame of die holder and bottom plate, wherein the die holder
Main frame is fixed on the bottom plate, and the end face of the bottom plate has extended around prestressing force side.
Particularly, the end face surrounding of bottom plate described in the prestressing force edge upwardly extends, and coordinates the prestressing force side in institute
The bottom surrounding for stating the main frame of die holder offers fixing groove, and the fixing groove of the main frame of die holder is set on the prestressing force side and leads to
The mode for crossing hot jacket is fixed on the bottom plate.
Beneficial effects of the present invention are that the large-scale rectangular die holder structure with prestressing force flanging is adopted compared with prior art
With the split structure being made of bottom plate and the main frame of die holder, and it is provided with prestressing force side on bottom plate, has the following advantages：
1) bottom plate increases the bearing strength that die holder is improved on stress side；
2) it improves the stress of die holder and eliminates region of stress concentration；
3) manufacture difficulty and manufacturing cost are greatly reduced, by actual use, there is very high techno-economic effect.
Description of the drawings
Fig. 1 is that the structure for the large-scale rectangular die holder structure with prestressing force flanging that the specific embodiment of the invention 1 provides is shown
It is intended to.
In figure：
1, the main frame of die holder；2, bottom plate；3, prestressing force side；4, fixing groove.
Specific implementation mode
Technical solution to further illustrate the present invention below with reference to the accompanying drawings and specific embodiments.
Refering to Figure 1, Fig. 1 is the large-scale rectangular mould with prestressing force flanging that the specific embodiment of the invention 1 provides
The structural schematic diagram of holder structure.
In the present embodiment, a kind of large-scale rectangular die holder structure with prestressing force flanging includes the main frame 1 of die holder and bottom plate 2, institute
It states the main frame of die holder 1 to be fixed on the bottom plate 2, the surrounding of the end face of the bottom plate 2 has upwardly extended prestressing force side 3.Cooperation institute
It states prestressing force side 3 and offers fixing groove 4 in the bottom surrounding of the main frame of the die holder 1, the fixing groove 4 of the main frame of the die holder 1 is arranged
It is fixed on the bottom plate 2 on the prestressing force side 3 and by way of hot jacket.
When installation, the main frame 1 of die holder that the bottom plate 2 is heated to certain temperature and cold conditions connects, and band bottom plate 2 is to mould after cooling
The main frame of seat 1 generates prodigious compression.
Above example is to elaborate that the basic principle and characteristic of the present invention, the present invention are not limited by above-mentioned example,
Without departing from the spirit and scope, the present invention also has various changes, these changes and modifications are both fallen within
In scope of the claimed invention.The scope of the present invention is defined by the appended claims and its equivalents.
