The utility model provides a kind of buckle shaving die of expanded letter shackle, solves more than technical problem.
What the purpose of this utility model was realized in：A kind of buckle shaving die of expanded letter shackle, it is described comprising lower die
Lower die be bolted on worktable upper surface, top board institute is connected with by motor drive rod above the workbench
Driving motor is provided with above the top board stated, it is characterised in that：The lower die is set as rectangle, in the rectangle
Cavity and cavity boss are provided with, the cavity is by first segment curve, second segment curve, third section curve and the 4th end curve
The closed surface being composed, the cavity divide two layers and run through lower die；The upper mold that the lower die is arranged above passes through spiral shell
Bolt is fixed on top board lower surface, and the upper mold includes upper mold fixed block and upper die briquetting；The upper die briquetting is arranged on
The surface of lower die cavity.
Preferably, the cavity of the lower die includes first layer cavity and second layer cavity, and the first layer cavity is small
In second layer cavity, the first layer cavity and second layer cavity use chamfered transition, and the first layer depth of cavity is small
In second layer depth of cavity.
Preferably, the first segment curve is set as 2 fonts.
Preferably, the second segment curve is set as 5 fonts.
Preferably, the lower die is provided with buckle with upper intermode.
The buckle shaving die of the utility model forging expanded letter shackle ensures that the buckle product overlap forged cutting is high
Effect, and section is neat；It is easy to operate, convenient for taking out the buckle of expanded letter shackle.

Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings, but not as the limitation to the utility model：
In the accompanying drawings：A kind of buckle shaving die of expanded letter shackle, comprising lower die 1, the lower die 1 is bolted
In 3 upper surface of workbench, 3 top of workbench is connected with by motor drive rod 5 on the top board 6 described in top board 6
Side is provided with driving motor 7, it is characterised in that：The lower die 1 is set as rectangle, and cavity is provided in the rectangle
With cavity boss, the cavity is by first segment curve 1-1, second segment curve 1-2, third section curve 1-3 and the 4th end curve
The closed surface being composed, the cavity divide two layers and run through lower die 1；The upper mold 2 that the lower die 1 is arranged above passes through
Bolt is fixed on 6 lower surface of top board, and the upper mold 2 includes upper mold fixed block 2-1 and upper die briquetting 2-2；The upper mold
Briquetting 2-2 is arranged on the surface of 1 cavity of lower die, and cutting efficiency is high, and trimming is neat, one-pass molding.
The cavity of the lower die 1 includes first layer cavity 1-5 and the second layer cavity 1-6, the first layer cavity 1-5
Less than second layer cavity 1-6, the first layer cavity 1-5 and second layer cavity 1-6 are using chamfered transition, the first layer
Cavity 1-5 depth is less than second layer cavity 1-6 depth, when cutting burrs, can be ejected and blocked by second layer cavity 1-6 from below
It detains 8 or strikes lower buckle 8 from top and pass through second layer cavity 1-6 taking-ups.
The first segment curve 1-1 is set as 2 fonts.
The second segment curve 1-2 is set as 5 fonts.
Buckle 8 is provided between the lower die 1 and upper mold 2.
When it is implemented, being provided with cavity in lower die 1, cavity is arranged above upper mold 2, is driven by driving motor 7
The buckle 8 of expanded letter shackle is pressed into lower die first layer cavity by top board 6, and upper and lower mould is processed using 45 steel, it is desirable that is heat-treated it
Rear surface hardness HRC40-42 ensures that machining accuracy and notch are smooth.
Above-described embodiment is only intended to clearly illustrate the description that the utility model is made, and not to the limit of embodiment
It is fixed, to those of ordinary skill in the art, other various forms of variations can also be made on the basis of the above description
