Abstract

The utility model discloses a buffer mechanism of a stripper plate. The buffer mechanism of the stripper plate comprises an upper die base, an upper base plate, the stripper plate, a height stopping screw, a spring, a cushion block and a higher sleeve. The upper die base, the upper base plate and the stripper plate are sequentially in contact from top to bottom, a through hole is formed in the upper base plate, a containing hole is formed in the upper die base, a nut, a spring and the cushion block of the height stopping screw are all arranged in the containing hole, the height stopping screw sequentially penetrates through the spring, the cushion block and the higher sleeve and then is fixedly connected with the stripper plate, one end of the spring abuts against the nut of the height stopping screw, and the other end of the spring abuts against the cushion block which abuts against the higher sleeve. According to the buffer mechanism of the stripper plate, when a precision stamping die machine tool operates at the high speed, the huge impact of the stripper plate on the height stopping screw is reduced through the anti-impact force of the spring when the stripper plate is bounced off at the high speed, the stress of the stripper plate is buffered, the aim that the machine tool is balanced in stress when the machine tool operates at the high speed is achieved, and the machine tool can stably operate for a long time under the high-speed state.

Description

The buffer gear of stripper plate

Technical field

The utility model belongs to the precise punching die machine tool field, relates in particular to a kind of buffer gear of stripper plate.

Background technology

The precise punching die lathe refers to the frequent collision by upper bolster and die shoe, makes raw material finally at the equipment of die for molding.Due to the precise punching die lathe, in when work, upper bolster and die shoe be in the high-speed cruising state, the shock that can reach more than 1000 times per minute.The speed of service so at a high speed, stripper plate can produce huge elastic force to stopping high screw, easily stops scrapping of high screw, stripper plate or backing plate.

The utility model content

For the weak point existed in above-mentioned technology, it is a kind of rational in infrastructure that the utility model provides, and can when the precise punching die machine tool high speed moves, play the buffer gear of comfort cushioning effect.

For achieving the above object, the utility model provides a kind of buffer gear of stripper plate, comprises upper bolster, upper padding plate, stripper plate, stops high screw, spring, cushion block and high cover; Described upper bolster, upper padding plate and stripper plate from top to bottom contact successively; Described upper padding plate is provided with through hole, and upper bolster is provided with accommodating hole, and described nut, spring and the cushion block that stops high screw all is placed in accommodating hole; Describedly stop high screw and be fixedly connected with stripper plate with after high cover through spring, cushion block successively, described spring one end is resisted against on the nut that stops high screw, and the other end is resisted against on cushion block, and cushion block is resisted against high putting.

Wherein, also be provided with clamping plate between described upper padding plate and stripper plate.

Wherein, the buffer gear of described stripper plate also comprises die shoe, lower bolster and lower bolster; Described die shoe, lower bolster and lower bolster contact from the bottom to top successively, and described lower bolster contacts with stripper plate; Described die shoe is provided with a slide bar, and described upper bolster is provided with the slideway suitable with slide bar, and described slide bar is contained in slideway.

Wherein, be provided with equally distributed ball between described slide bar and slideway.

The beneficial effects of the utility model are: compared to prior art; the buffer gear of the stripper plate that the utility model provides; when the precise punching die machine tool high speed moves; anti-force by spring reduce stripper plate when flicking at a high speed to stopping the enormous impact power of high screw; the impulsive force of the high screw of buffering stop to upper padding plate; make stripper plate, stop stressed more steady between high screw and upper padding plate three; reach lathe stress balance when high-speed cruising, guarantee lathe stable operation under the ultrahigh speed state for a long time.

The specific embodiment

In order more clearly to explain the utility model, below in conjunction with accompanying drawing, the utility model is further described.

Refer to Fig. 1, the buffer gear of the stripper plate that the utility model provides, comprise upper bolster 11, upper padding plate 13, stripper plate 14, stops high screw 18, spring 19, cushion block 20 and high cover 21; Upper bolster 11, upper padding plate 13 and stripper plate 14 from top to bottom contact successively; Upper padding plate 13 is provided with through hole, and upper bolster 11 is provided with accommodating hole 111, and the nut, spring 19 and the cushion block 20 that stop high screw 18 all are placed in accommodating hole 111; Stop high screw 18 successively through being fixedly connected with stripper plate 14 after spring 19, cushion block 20 and high cover 21, spring 19 1 ends are resisted against on the nut that stops high screw 18, and the other end is resisted against on cushion block 20, and cushion block 20 is resisted against on high cover 21.

The buffer gear of the stripper plate that the utility model provides, its specific works principle is: upper bolster 11 moves up and down with upper padding plate 13 relative stripper plate 14 together, when upper bolster 11 and upper padding plate 13 move upward, upper padding plate 13 drives cushion block 20 and moves upward, cushion block 20 is Compress Spring 19 upwards, an end that stops high screw 18 is fixedly connected with stripper plate 14, and the nut of the other end props up spring 19; When upper bolster 11 and upper padding plate 13 move downward, spring 19 discharges, until propped up by high cover 21.

Compared to prior art; the buffer gear of the stripper plate that the utility model provides; when the precise punching die machine tool high speed moves; anti-force by spring 19 reduce stripper plate 14 when flicking at a high speed to stopping the enormous impact power of high screw 18; the impulsive force of 18 pairs of upper padding plates 13 of the high screw of buffering stop; make stripper plate 14, stop stressed more steady between high screw 18 and upper padding plate 13 threes; reach lathe stress balance when high-speed cruising, guarantee lathe stable operation under the ultrahigh speed state for a long time.The utility model precise structure, purposes is wide, is applicable to high precision, ultrahigh speed stamping die.

The buffer gear of the stripper plate that the utility model provides, also be provided with clamping plate 12 between upper padding plate 13 and stripper plate 14.Clamping plate 12 can further cushion stripper plate 14 when flicking at a high speed, to stopping the enormous impact power of high screw 18, also can cushion upper bolster 11 in descending process, to the impulsive force of stripper plate 14.

The buffer gear of the stripper plate that the utility model provides, the buffer gear of stripper plate also comprises die shoe 17, lower bolster 16 and lower bolster 15; Die shoe 17, lower bolster 16 and lower bolster 15 contact from the bottom to top successively, and lower bolster 15 contacts with stripper plate 14; Die shoe 17 is provided with a slide bar 171, and upper bolster 11 is provided with the slideway 112 suitable with slide bar 171, and slide bar 171 is contained in slideway 112.Mutually adaptive slideway 112 and slide bar 171, play the effect of guiding, can guarantee that upper bolster 11 and die shoe 17 move along the axis direction of slide bar 171 all the time, guarantees stripper plate 14 and lower bolster 15 good contacts, stripper plate 14 stressed evenly, not to damage.

The buffer gear of the stripper plate that the utility model provides, be provided with equally distributed ball 22 between slide bar 171 and slideway 112.In order to reduce under the high-speed cruising state, frictional force between slide bar 171 and slideway 112, reduce wear, increase work efficiency, the utility model is provided with a plurality of balls 22 between slide bar 171 and slideway 112, ball 22 is evenly distributed between slide bar 171 and slideway 112, can play good lubrication.
