Abstract
The utility model discloses a rotary type bending punch mechanism of a progressive die. On an upper die, a bending punch is fixed on a fixing plate, a return spring is fixed on a discharging bearing plate in the horizontal direction, and one end of the return spring presses to the bending punch 6; and on a lower die, a bending female die is fixed on a female die plate, a punch guide block is mounted on the female die plate, a compressing spring is arranged at the upper end on the left side of the punch guide block, the inclined surface at the bottom end of the punch guide block is in contact with an inclined sliding block, and an adjusting bolt mounted on a side surface of the female die plate is connected onto the inclined sliding block. The rotary type bending punch mechanism has the effects as follows: the rotary type bending punch mechanism effectively solves the technical problem that, for parts with inner R corner requirements in a bending and forming part of a part, the progressive die can not ensure accuracy requirements of angular dimensions of a bent part, through practical application, compared with a traditional structure, after the process step of bending, a reshaping procedure is not required, the bent angle of a part can reach 90 DEG or be smaller than 90 DEG, and bending interval is convenient to adjust according to different material thickness.
Description
Technical field
The utility model belongs to the mould of machining, and is particularly a kind of along sending the rotary crooked formed punch of mould mechanism.
Background technology
In Modern Mold is designed and developed, for the stamping parts that batch is large, dimension precision requirement is high, the general employing along sending mould production, to enhance productivity and to guarantee dimension precision requirement, the part that interior R angle requirement is arranged for the spares bend moulding section, along in sending Design of Dies and development process, be difficult to guarantee the required precision of sweep Angular Dimension.
The utility model content
Technical problem to be solved in the utility model is: provide a kind of along sending the rotary crooked formed punch of mould mechanism.This effectively solves above-mentioned technical barrier along sending the rotary crooked formed punch of mould mechanism, passes through application in practice, compare with traditional structure, after crooked work step, do not need trimming, the spares bend angle just can reach 90 the degree or less than 90 the degree, and according to the material thick difference, facilitate the bent gap adjustment.
The technical solution of the utility model is:
A kind of along sending the rotary crooked formed punch of mould mechanism, it is characterized in that: on upper mould, crooked formed punch 6 is fixed on fixed head 1 by drift steady pin 4, returning spring 5 horizontal directions are fixed on discharging backing plate 12, discharging backing plate 12 is arranged between stripper and fixed head, and a side pressure of multiple spring is to crooked formed punch 6; On lower mould, bending die 7 is fixed on concave template 3, and drift guide pad 8 is arranged on concave template 3, and there is holddown spring 9 upper end, drift guide pad side, inclined-plane, drift guide pad bottom contacts with angled-lift splits 10, and the adjustment bolt 11 that is contained in the concave template side is connected on angled-lift splits 10.
The utility model effect is:
This is along sending the rotary crooked formed punch of mould mechanism, effectively solved along sending mould to have the part of interior R angle requirement to be difficult to guarantee the technical barrier of sweep Angular Dimension required precision for the spares bend moulding section, pass through application in practice, compare with traditional structure, after crooked work step, do not need trimming, the spares bend angle just can reach 90 degree or spend less than 90, and according to the thick difference of material, facilitate the bent gap adjustment.
Description of drawings
Fig. 1 is along sending the mechanism's work of the rotary crooked formed punch of mould front schematic diagram
Fig. 2 is in schematic diagram figure when sending the rotary crooked formed punch of mould mechanism work: 1. fixed head; 2. stripper; 3. concave template; 4. drift steady pin; 5. returning spring; 6. crooked formed punch; 7. bending die; 8. drift guide pad; 9. holddown spring; 10. angled-lift splits; 11. adjustment bolt; 12. discharging backing plate.
The specific embodiment
As shown in the figure a kind of along sending the rotary crooked formed punch of mould mechanism, on upper mould, crooked formed punch 6 is fixed on fixed head 1 by drift steady pin 4, returning spring 5 horizontal directions are fixed on discharging backing plate 12, discharging backing plate 12 is arranged between stripper and fixed head, and a side pressure of returning spring is to crooked formed punch 6; On lower mould, bending die 7 is fixed on concave template 3, and drift guide pad 8 is arranged on concave template 3, and there is holddown spring 9 upper end, drift guide pad side, inclined-plane, drift guide pad bottom contacts with angled-lift splits 10, and the adjustment bolt 11 that is contained in the concave template side is connected on angled-lift splits 10.
its course of work is as follows: crooked formed punch working face one side and fixed head, stripper has the gap of 0.3mm-0.5mm, in the matched moulds process, stripper first contacts strip and concave template compresses, the crooked formed punch working face forms crooked the time the spares bend direction that faces down, crooked formed punch opposite side inclined-plane and the sliding-contact of drift guide pad ramp, make crooked formed punch form one to the right side force, this side force drives crooked formed punch and rotates take the drift steady pin as the center of circle, the spares bend face is being subject to downwards and is counterclockwise rotating under the effect of resultant force, complete BENDING PROCESS, mould is at lower dead point position, BENDING PROCESS finishes, after mold open, returning spring sets back crooked formed punch left.During due to raw material thickness and mechanical performance variation needs adjustment angle of bend, can angled-lift splits be moved right by adjusting bolt, drive the drift guide pad and move right, and change crooked formed punch in the matched moulds process, the bending die gap, make the spares bend angle satisfy the drawing required precision.
The research and development of rotary crooked formed punch mechanism, thoroughly solved because spares bend has interior R requirement, crooked root resilience is large, and angle of bend does not reach this technical difficult problem of drawing requirement, and this bending mechanism can make angle of bend less than 90 degree, the little characteristics of the crooked vestige of spares bend face.
