Abstract
The utility model relates to a combined installation insert-type structure, which is characterized in that a terrace die is formed by sequentially joining terrace die inserts onto a terrace die installation plate, wherein the terrace die installation plate is fixedly connected with the top of an upper soleplate; a concave die is formed by sequentially installing concave die inserts onto a concave die installation plate and integrally installing the concave die installation plate to the top of a lower soleplate, an ejection device is formed by sequentially installing ejection device inserts onto an ejection device installation plate, and the ejection device is pushed by a supporting rod to move up and down inside a notch of the concave die; a joint seam among each terrace die insert, each concave die insert and each ejection device insert is respectively provided with a gap of 1.5mm to 2mm, and a lute circle of the notch of the concave die is of a spherical surface, and other parts of the notch of the concave die is connected with a R30 concave die circular angle after being respectively in a slope angle of 15DEG. By reserving the gaps among the inserts and modifying the shape of the concave die notch, the problems of cracking of a vehicle axle with a set square, spalling of the concave die and inconvenience in repairing can be solved.
Description
Technical field
The utility model relates to a kind of combination the block insert type structure is installed, and is applicable to set square with not with the thick blanks automobile axle half shells by hot forming mould of two types of set squares.
Background technology
Traditional truck vehicle bridge is cast article, and for production efficiency and the product quality that improves the truck vehicle bridge, the production technology of vehicle bridge is changed into welding behind the half shell heat stamping and shaping by casting finishes automobile axle half shells by hot forming technology of die manufacturing domestic blank.Abroad axle housing heat pressing and molding mold manufacturing technology is bottled up, import is offered every mold up to 2,000,000 RMB.
Summary of the invention
The purpose of this utility model is to provide a kind of combination that the block insert type structure is installed, gap between it is inserted by reservation, the transformation of die mouth-shaped, solved the problem with the drawing crack of set square vehicle bridge, die spalling and inconvenient maintenance, it has satisfied the product quality requirement, easy to maintenance, also can when producing the two or more profiles product close with size, only change working portion, share upper and lower bottom plate, reduce die cost, reduce the manufacturing cycle.
The technical solution of the utility model is achieved in that combination installation block insert type structure, is comprised of punch, die, backing-out punch, punch installing plate, die installing plate, backing-out punch installing plate, upper plate, lower shoe; It is characterized in that: punch is fixedly connected sequentially on the punch installing plate by punch insert, and the punch installing plate is fixedly connected with the upper plate top; Integral installation was at the lower shoe top again after die was installed on the die installing plate by die plate insert successively, and backing-out punch is inserted by backing-out punch and sequentially is installed on the backing-out punch installing plate, is promoted to fluctuate in the die mouth by pressure pin; Punch insert, die plate insert and backing-out punch insert respectively insert between the joint close place all reserve the gap of 1.5mm-2mm, the Chinese lute circle place of die mouth is sphere, other parts are the die entrance that meets again R30 after 15 ° of slope angles.
Described punch is assembled nine punch inserts symmetries by screw.
Described die is one group of symmetrical assembling by screw with two of six die plate inserts of two groups of symmetries.
Described backing-out punch by screw with the backing-out punch assembling of inserting.
Described die mouth falls the die entrance that meets again R30 after 15 ° of slope angles to whole die mouth during not with set square.
Good effect of the present utility model is gap, the transformation of die mouth-shaped between it is inserted by reservation, has solved the problem with the drawing crack of set square vehicle bridge, die spalling and inconvenient maintenance.

Fig. 2 is hot-pressing forming die front view of the present utility model.
Fig. 3 is hot-pressing forming die cutaway view of the present utility model.
Fig. 4 is die plate insert figure of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further: the block insert type structure is installed in combination, is comprised of punch, die, backing-out punch, punch installing plate 4, die installing plate 5, backing-out punch installing plate 6, upper plate 7, lower shoe 8; It is characterized in that: punch is fixedly connected sequentially on punch installing plate 4 by punch insert 1, and punch installing plate 4 is fixedly connected with upper plate 7 tops; Integral installation was at lower shoe 8 tops again after die was installed on the die installing plate 5 successively by die plate insert 2, and backing-out punch is installed on the backing-out punch installing plate 6 by backing-out punch 3 orders of inserting, and is promoted to fluctuate in die mouth 9 by pressure pin; All reserve the gap of 1.5mm-2mm at insert joint close place between 3 respectively insert of punch insert 1, die plate insert 2 and backing-out punch, the Chinese lute circle place of die mouth 9 is sphere, and other parts are the die entrance that meets again R30 after 15 ° of slope angles.
Making is during with back axle half shell of set square, plate after the heating is put on the die that assembles, the dependence locating piece positions, during the beginning moulding, the punch insert 1 that links together, punch installing plate 4, upper plate 7 is descending, plate after punch insert 1 will heat is pressed in the die plate insert 2 that assembles successively and reserve the 1.5mm-2mm gap, after the moulding pressurize is finished, the punch insert 1 that links together is simultaneously up with punch installing plate 4 and upper plate 7, five backing-out punch that link together insert 2 under the pushing tow of pressure pin, and the part after the moulding is ejected die mouth 9.The Chinese lute of die mouth 9 circle place is sphere, and other parts are the die entrance that meets again R30 after 15 ° of slope angles; Simultaneously, push rod promote to be promoted the part that makes after the moulding by push pedal and is broken away from punch insert 1, finishes so far the molded overall process of axle hot.
When making not back axle half shell with set square, die mouth 9 all is to be the die entrance that meets again R30 after 15 ° of slope angles.Other process are identical during with back axle half shell made with set square.
