Abstract
The utility model relates to a structure for preventing material-lifting floating nail from upward-jumping, which comprises a rectangular floating nail, screws and plug screws; the height of the rectangular floating nail is larger than 32 mm, and the inside of the rectangular floating nail is provided with a pair of limiting sleeves, and the inside of the limiting sleeves are threadedly connected with the screws respectively, and the head of the screw is connected with the plug screw through a spring. The beneficial effects of the structure for preventing material-lifting floating nail from upward-jumping are as follows: the height of the rectangular floating nail is larger than 32 mm, and the punching travel route of general high-speed punching progressive die is 30 mm, when the die is at the dead center position of the high-speed punching machine, that is, the punching travel route is at the highest speed of 30 mm, the height of the rectangular floating nail is larger than that of the punching travel route, therefore, there is not enough space for pumping, and the material-lifting floating nail is effectively prevented from upward-jumping from the concave die surface, and the damage to a punch-die caused by the upward-jumping of the material-lifting floating nail is prevented, and the damage to the die can also be avoided.
Description
Technical field
The utility model relates to a kind of floating structure that nails on jumping of material lift that prevents.
Background technology
At present, electric machine iron core high-speed carbide punching press industry, mould is to high speed, automation direction development.For common single-row stator-rotor iron core, less because of product itself, so expect that wide step pitch is also less relatively, feeding can meet the demands.But for big (as wind-power electricity generation) mould, feeding will be aspired for stability, and is reliable, at this moment just need use rectangle and float pin structure for three row or step pitch.For the floating pin structure of common circle, less because of the floating nail of circle diameter range of application, general diameter is 6～20mm, therefore carrying material bar area is limited, and progressive die is when material bar tail end, and it is more that material bar itself is gone out the hole, poor rigidity, the floating nail of circle easily fall in the hole that the material bar before goes out, and stablize and influence feeding.The application of the floating pin structure of rectangle can effectively overcome this difficult point, long floating nail is longer because of length, loaded area is bigger, thereby make the material bar all the time at the floating face that nails on, and feeding is stable, but state's inner mold uses long floating pin structure, dismounting inconvenience at present, not easy care and repairing, the floating staple height in side is generally lower, at a high speed towards progressive die mould drawing velocity reach 200～500 jig frequencies/minute, this moment, mould was owing to run up, when punch press rises to upper dead center position by lower dead point position, mould inside produces vacuum, has absorption affinity, also easily produces dither in the punching course, make screw and floating oncomelania line junction loosening, cause screw and floating nail to throw off, this moment, floating nail was easily jumped out in concave template, thus mold damage, the floating nail in the side of causing is jumped out on the concave template, cause punch and die tipping, make mould cause great damage, when serious, also can penetrate by the floating nail in the side of making in the punching course, cause operating personnel's injures and deaths.
The utility model content
The purpose of this utility model provides this suitable novel purpose and provides a kind of floating structure that nails on jumping of material lift that prevents, effectively avoids existing floating to nail on jumping, causes mould to damage the phenomenon of operating personnel's injures and deaths.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of floating structure that nails on jumping of material lift that prevents, comprise that rectangle floats nail, screw and plug screw, the height of the floating nail of described rectangle is greater than 32mm, and the inside of the floating nail of rectangle is provided with a pair of stop collar, the screw that has been threaded respectively in the stop collar, the head of screw is connected with plug screw by spring.
The beneficial effects of the utility model are: the floating staple height of rectangle is greater than 32mm, general is 30mm towards progressive die mould punching stroke at a high speed, when mould during at the high velocity ram machine upper dead center position, when being punching stroke maximum height 30mm, the floating staple height of rectangle is greater than the punching stroke height, thereby do not have enough height space to eject effectively to prevent the floating nail of material lift from jumping, prevent to jump destruction punch-die, mold damage because of floating nailing on from the die face.
Description of drawings
Fig. 1 is the described a kind of floating STRUCTURE DECOMPOSITION schematic diagram that nails on the structure of jumping of material lift that prevents of the utility model embodiment.
Among the figure:
1, the floating nail of rectangle; 2, stop collar; 3, screw; 4, spring; 5, plug screw.
The specific embodiment
As shown in Figure 1, the described a kind of floating structure that nails on jumping of material lift that prevents of the utility model embodiment, comprise the floating nail 1 of rectangle, screw 3 and plug screw 5, the height of the floating nail 1 of described rectangle is greater than 32mm, the inside of the floating nail 1 of rectangle is provided with a pair of stop collar 2, the screw 3 that has been threaded respectively in the stop collar 2, the head of screw 3 is connected with plug screw 5 by spring 4.
During concrete the use, when mould at the high velocity ram machine upper dead center position, when being punching stroke maximum height 30mm, because the floating nail 1 of rectangle highly is greater than 32mm, floating nail 1 height of rectangle this moment is greater than the punching stroke height, do not have to jump on enough height space, thereby prevent that effectively the floating nail of material lift from jumping from the die face, prevent to jump destruction punch-die mold damage because of floating nailing on.
Claims (1)
1. one kind prevents the floating structure that nails on jumping of material lift, comprise the floating nail of rectangle (1), screw (3) and plug screw (5), it is characterized in that: the height of the floating nail of described rectangle (1) is greater than 32mm, the inside of the floating nail of rectangle (1) is provided with a pair of stop collar (2), the screw (3) that has been threaded respectively in the stop collar (2), the head of screw (3) is connected with plug screw (5) by spring (4).
