Abstract
A round snap ring bending mold comprises a mold handle, a convex mold fixedly connected to the mold handle, a base, a fixing seat fixedly installed on the base and a concave mold, wherein a movable plate is arranged in the fixing seat; the concave mold is arranged on the movable plate and composed of two half mold bodies which are symmetrically installed on the fixing seat through fixing pins and can rotate around the fixing pins; the half mold bodies are fixedly provided with positioning blocks; an ejection rod is arranged on the base, a spring is arranged between the base and the ejection rod, and the ejection rod abuts against the bottom surface of the movable plate. The round snap ring bending mold is compact in structure and reliable in bending forming. The quality consistency of a formed round snap ring is good, and the part is small in resilience. The practice proves that the bending mold is suitable for bending forming of small round ring parts.
Description
Technical field
The present invention relates to a kind of bending mould, particularly a kind of round clasp one-shot forming bending mould.
Background technology
A kind of round clasp, is adopted 65Mn spring steel by brake forming, often needs to be bent by multiple working procedure, cause working (machining) efficiency lower, and shaping quality can not be guaranteed, and add the labour intensity of operation in production process in the past.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of by first order buckling and plastic round clasp bending mould.
For solving the problems of the technologies described above, present invention employs a kind of round clasp bending mould, comprise die shank, be fixedly connected on the punch on die shank, base, be fixedly mounted on the holder on base, die, portable plate is provided with in described holder, described die is arranged on portable plate, described die is made up of two half modules, described half module is arranged on holder respectively by steady pin symmetry, described half module can rotate around steady pin, described half module is installed with locating piece, described base is provided with push rod, spring is provided with between described base and push rod, described push rod withstands on portable plate bottom surface.
Compact conformation of the present invention, bending forming is reliable, and the round clasp quality conformance after shaping is better, and part resilience is little, facts have proved, this bending mould is suitable for the brake forming of small-sized annulus part.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is working state structure schematic diagram of the present invention.
In figure, 1, die shank; 2, punch; 3, base; 4, holder; 5, half module; 6, locating piece; 7, steady pin; 8, spring; 9, push rod; 10, portable plate; 11, workpiece.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further illustrated.
With reference to Fig. 1 and 2, for a kind of round clasp bending mould, comprise die shank 1, be fixedly connected on the punch 2 on die shank 1, base 3, fixedly mount holder 4 on the base 3 and die, portable plate 10 is provided with in described holder 4, described die is arranged on portable plate 10, described die is made up of two half modules 5, described half module 5 is arranged on holder 4 respectively by steady pin 7 symmetry, described half module 5 can rotate around steady pin 7, described half module 5 is installed with locating piece 6, described base 3 is provided with push rod 9, spring 8 is provided with between described base 3 and push rod 9, described push rod 9 withstands on portable plate 10 bottom surface.
As shown in Figure 2, the course of work of this mould is: before punching press starts, and spring 8 is by portable plate 10 jack-up, and now die is horizontal, and two half modules 5 of die, in the state of dividing right and left, can rotate around steady pin 7; Blank on clamping on locating piece 6, punch press declines, and blank is pressed into U-shaped in advance by punch 2, continues to decline, and punch 2 forces two half modules 5 to rotate around steady pin 7; When punch press drop to be in extreme lower position time, two half modules 5 rotate to position blank wrapped on punch 2 just, complete bending forming.During backhaul, die 5 by jack-up, comes back to horizontal level, is taken off by workpiece 11 from punch 2 under the effect of spring 8 and push rod 9.
Claims (1)
