The specific embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is described in further detail:
The utility model provides a kind of rolling die, as depicted in figs. 1 and 2, comprises roller adjustment screw 1, roller adjustment rack 2, punch-die roller, the first discharging polyurethane rubber 3-1, punch-die roller core 3-2, the second discharging polyurethane rubber 3-3, a plurality of punch-die 3-4, frame 5, die roller, polyurethane rubber die 6-1, die roller core 6-2, sprocket wheel 7, the first gear 8-1 and the second gear 8-2, wherein, roller adjustment rack 2 comprises support and bearing block, the equally distributed punch-die 3-4 of a circle is equipped with on the surface of punch-die roller core 3-2, on described punch-die 3-4, there is the second discharging polyurethane rubber 3-3, the outer surface of described punch-die roller core 3-2 is covered with one deck the first discharging polyurethane rubber 3-1, the two ends of punch-die roller are respectively provided with a roller adjustment rack 2, die roller core 6-2 is provided with cannelure, and polyurethane rubber die 6-1 is housed in cannelure, and bearing block is fixed by bolts on rack side wall, roller adjustment screw 1 is equipped with in support upper surface, and roller adjustment rack 2 is fixed by bolts to the upper surface of frame.
Sprocket wheel 7 is connected with flat key with die roller, and the first gear 8-1, the second gear 8-2 identical with a pair of parameter and the straight tooth column in normal engagement are coaxial respectively again for die roller and punch-die roller, and connect by flat key.The difference of the pitch circle of the maximum outside diameter of punch-die roller and the first gear 8-1 be material to be punched thickness 1/2nd, equally, the difference of the pitch circle of the maximum outside diameter of die roller and the second gear 8-2 be little material to be punched thickness 1/2nd, with equation expression following (thickness that t/2 is material to be punched):
Pitch circle=the t/2 of maximum outside diameter-the first gear of punch-die roller;
Pitch circle=the t/2 of maximum outside diameter-the second gear of die roller.
Radial clearance between punch-die roller and die roller is t, (thickness that t is material to be punched), stamping material passes through from gap under the drive of punch-die roller and die roller, and the gap of punch-die roller and die roller also can be adjusted by roller adjustment rack 2.Punch-die 3-4 is housed on punch-die roller, its material adopts high-wearing feature and high-intensity rigid material, be preferably carbon tool steel, be called for short T10, punch-die 3-4 and punch-die roller core 3-2 adopt interference fit, and the work cutting edge of punch-die 3-4 exceeds 1 ~ 2mm than the external diameter of punch-die roller, punch-die roller core 3-2 overcoat has the first discharging polyurethane rubber 3-1 that 5mm is thick, play binder and discharging effect, the second discharging polyurethane rubber 3-3 is also housed in punch-die 3-4, play discharging effect; On die roller core 6-2, be provided with cannelure, cannelure plays die and holds frame effect, and polyurethane rubber die 6-1 is housed in cannelure, and the work cambered surface of polyurethane rubber die 6-1 is consistent with the outside dimension of die roller core 6-2.Roller is adjusted the upper-lower position of screw 1 and the adjustable punch-die roller of roller adjustment rack 2, guarantees the gap between die roller and punch-die roller.
The structure enlarged drawing of rolling die of the present utility model as shown in Figure 3, punch-die roller and die roller are along with the rotation of gear is done respectively counterclockwise and clockwise rotates, and drive stamping material to send to by feed direction, at stamping material upper and lower sides, form punch-die and die respectively.Because the punch-die 3-4 that uses T10 to make has hard sharp cutting edge, and polyurethane rubber die 6-1 adopts hardness higher, wear-resisting, tear resistance stronger polyurethane rubber make, so, punch-die 3-4 starts and along with the continuation of rotating from contact stamping material, its cutting edge constantly stretches into stamping material, and polyurethane rubber die 6-1 can produce enough pressure, to overcome the shear strength of stamping material, make stamping material through strain, plastic deformation, fracture, until punch-die is pressed into the certain degree of depth of polyurethane rubber, make the complete separation of stamping material and reach stamping-out object.The workpiece 9 that stamping-out gets off falls automatically, and billot 4 and waste material 10, on punch-die 3-4, are released by the first discharging polyurethane rubber 3-1 and the second discharging polyurethane rubber 3-3 in the middle of punch-die roller core 3-2 outside and punch-die 3-4, complete discharging.
Because punch-die 3-4 bottom surface is flat, in punch-die cutting edge when work, contacts from starting to touch to exit with plate, progresses into and exit stamping-out, and whole process is equivalent to oblique sword stamping-out process, and blanking pressure is little, and part accuracy height is without burr.A plurality of punch-die 3-4 are housed on one week of punch-die roller, and whole stamping-out process is successive, there is no idle stroke, has greatly improved ram efficiency.
By reference to the accompanying drawings embodiment of the present utility model is explained in detail above, but the utility model is not limited to above-mentioned embodiment, in the ken possessing those of ordinary skills, can also under the prerequisite that does not depart from the utility model aim, make a variety of changes.
