Abstract
The utility model discloses a lever mechanism for a smoothly-conveying mold in bending and shaping processes. A vertical force transmission rod is arranged on a base of an upper mold; the upper end of the vertical force transmission rod is provided with a wedge-shaped adjusting sliding block; the outer side of the wedge-shaped adjusting sliding block is provided with an adjusting bolt; the vertical force transmission rod penetrates through an unloading plate; the axis of the vertical force transmission rod and the axis of a stressing column arranged on a base of a lower mold are in a same vertical line; the lower end of the movable stressing column arranged on the base of the lower mold is contacted with one end of a lever in the base of the lower mold; the lower end of a force supporting column arranged in the base of the lower mold is contacted above the other end of the lever; the upper end of the force supporting column is connected with the lower end of a bending punch; and the force supporting column is externally provided with a return spring. According to the lever mechanism for the smoothly-conveying mold in the bending and shaping processes, a lever mechanism technology is adopted, the punching times of a mold cutter edge are improved by more than two times, so that the production efficiency is improved and the punching production cost is reduced, and the whole service life of a mold is prolonged by three times compared with the traditional structure.
Description
Technical field
The utility model belongs to the machining mould, and is particularly a kind of along sending mould crooked trimming leverage.
Background technology
In the electric in modern times and stamping parts of automobile field; Extensive use is along sending mould production, and its production efficiency and element precision are high, but for last warp architecture, the thick part more than 1mm of material are arranged; In the punching production process; Mould is before stripper and concave template matched moulds, because stripper receives pressure-plate-force and bending force run-off the straight upwards, thereby influences mold integral production precision and life-span.
The utility model content
The purpose of the utility model provides a kind of along sending mould crooked trimming leverage.It,, is compared with traditional structure through practical application developing the leverage technology along sending in the crooked trimming of mould according to lever principle, and mould sharpening jig frequency improves more than 2 times, thereby enhances productivity, and reduces the punching production cost; The mold integral life-span is brought up to more than 3 times.
The particular content of the utility model:
A kind of mould has the patrix base, on the patrix base, stripper is arranged along sending mould crooked trimming leverage, is connected with crooked die below the stripper; Counterdie base backing plate is arranged; Have on the counterdie base backing plate on counterdie base, the counterdie base concave template is arranged; Crooked formed punch is arranged on the concave template, it is characterized in that: vertical transmission rod is arranged on the patrix base, and there is wedge shape adjustment slide block vertical transmission rod upper end; There is the adjustment bolt in the wedge shape adjustment slide block outside, and vertical transmission rod passes stripper; Vertical transmission rod axle center and the force column axle center on the counterdie base are on same vertical curve; Be contained in the lower end and lever one end in contact that is contained in the counterdie base of the force column of the activity on the counterdie base; End in contact under the top of the lever other end and the holder power post that is contained in the counterdie base; Holder power post upper end is connected with the crooked formed punch lower end, and holder power post has returning spring outward.
The characteristic advantage of the utility model:
It is adopting the leverage technology according to lever principle along sending in the crooked trimming of mould, and it is compared with traditional structure has, and mould sharpening jig frequency improves more than 2 times, thereby enhances productivity, and reduces the punching production cost; The mold integral life-span is brought up to more than 3 times.
Description of drawings
Fig. 1 is a leverage work front mold drawing.
Mould drawing when Fig. 2 works for leverage.
Among the figure: 1. counterdie base backing plate; 2. counterdie base; 3. concave template; 4. stripper; 5. patrix base; 6. adjustment slide block; 7. adjustment bolt; 8. transmission rod; 9. force column; 10. lever; 11. returning spring; 12. holder power post; 13. crooked formed punch; 14. crooked die.
The specific embodiment
As shown in the figure a kind of mould has the patrix base, on the patrix base, stripper is arranged along sending mould crooked trimming leverage, is connected with crooked die below the stripper; Counterdie base backing plate is arranged; Have on the counterdie base backing plate on counterdie base, the counterdie base concave template is arranged; There is crooked formed punch that vertical transmission rod is arranged on the patrix base on the concave template; There is wedge shape adjustment slide block vertical transmission rod upper end, and there is the adjustment bolt in the wedge shape adjustment slide block outside, and vertical transmission rod passes stripper; Vertical transmission rod axle center and the force column axle center on the counterdie base are on same vertical curve; Be contained in the lower end and lever one end in contact that is contained in the counterdie base of the force column of the activity on the counterdie base; End in contact under the top of the lever other end and the holder power post that is contained in the counterdie base; Holder power post upper end is connected with the crooked formed punch lower end, and holder power post has returning spring outward.
Utilize the physics lever principle, designing leverage in the mould along sending, be applied on the part crooked and following crooked part dimensional accuracy and adjust in the operation; The course of work is following: in the matched moulds process, after stripper elder generation contact strip and concave template compressed, the mould mo(u)ld top half drove transmission rod and passes to force column to descending power; Force column is passed to lever to descending power, and the descending power of lever harrow converts up power to and passes to holder power post, and returning spring is compressed; The moving crooked formed punch of holder power cornice is bent upwards or adjusts, and mould is at lower dead point position, and whole bending or adjustment operation are accomplished; Behind the mold open, returning spring sets back entire mechanism, through adjustment bolt and adjustment slide block; The height of power transmission thick stick can be adjusted, the height of crooked formed punch can be adjusted through leverage, to satisfy the parts size precision requirement.
Leverage is in crooked and adjustment operation process, and first binder is crooked again because the course of work is whole stripper, and it can prevent stopping materials strip minute movement in BENDING PROCESS, thereby satisfies the spares bend dimension precision requirement in process of production; Simultaneously, but bending force on this mechanism's balance prevents the stressed inclination of stripper, thereby has improved stripper guiding accuracy and mold integral life-span.
