Detailed Description
The utility model will be further described with reference to the drawings and detailed description.
As shown in fig. 1, the utility model discloses a spoke hole forming die for processing a middle hole 51 and/or a bolt hole 52 on a spoke 5, which comprises an upper die 3, a lower die 4 and a positioning piece 1, wherein the upper die 3 and the lower die 4 are arranged vertically opposite, the upper die 3 comprises a punch 35 and an upper die core 36 for pressing the upper end face of the spoke 5, the punch 35 is used for punching the middle hole 51 and/or the bolt hole 52 or for extruding and forming a chamfer at the orifice of the bolt hole 52, the lower die 4 comprises a lower die core 43 which is positioned below the spoke 5 and horizontally supports the spoke 5, the positioning piece 1 is horizontally arranged outside the upper die core 36 or the lower die core 43 in a surrounding manner and can be lifted and adjusted, and when the positioning piece 1 is close to the spoke 5, the inner side face of the positioning piece 1 is close to the side wall face of the spoke 5 so as to fix the spoke 5 in the horizontal direction. When the spacer 1 is far from the spoke 5, the spacer 1 is located on the side opposite to the edge of the spoke 5. That is, when the edge of the spoke 5 after bending faces the lower die 4, the positioning piece 1 is positioned at one side of the upper die 3, and when the spoke 5 is close to the lower die, the positioning piece is relatively convenient to prop against the side wall surface of the spoke 5; the opposite is true when the rim of the spoke 5 is directed towards the upper die 3. When the horizontal position of the spoke 5 deviates, the spoke 5 can be pushed to push the spoke 5 to the target position under the supporting action of the positioning piece 1, and the position deviation correction is realized in the radial direction of the spoke.
The locating piece 1 can be of an integral design, as shown in fig. 2, the locating piece 1 is preferably in a circular ring shape, the spoke 5 is convenient and comprehensive to limit, the locating effect is good, and when the inner side surface of the locating piece 1 is an arc surface, the limiting effect is better. In addition, the corners of the inner upper end and/or the corners of the inner lower end of the positioning member 1 may be rounded or beveled. The corner that sets up chamfer or chamfer is selected according to the position that setting element 1 established, and when setting element 1 was located 3 one sides of last mould, the corner department that sets up chamfer or chamfer in setting element 1 inboard lower extreme can make the contact between setting element 1 and the spoke 5 more smooth through chamfer or chamfer, and setting element 1 is difficult to fish tail spoke 5 surface when going down near spoke 5.

The limiting and correcting effects similar to those of the integral locating piece 1 can be achieved through the three-way locating of at least three locating pieces 1 in the radial direction of the spoke.
The positioning member 1 is lifted by a specific lifting device, but is preferably fixed to the upper die 3 or the lower die 4, and is lifted directly with the upper die 3 or the lower die 4 when punching or extruding holes. At this time, the mold further comprises a first backing plate 2, wherein the first backing plate 2 is positioned on one side of the positioning piece 1, which is away from the spoke 5, and the positioning piece 1 is fixedly connected with the upper mold 3 or the lower mold 4, and when the position deviation of the positioning piece 1 in the vertical direction is large, the first backing plate 2 with different heights can be replaced for adjustment.
As shown in fig. 4 and 5, the upper retainer 38 is fixedly fitted to the outer side of the upper mold core 36, the lower retainer 47 is fixedly fitted to the outer side of the lower mold core 43, the upper retainer 38 and the lower retainer 47 are disposed vertically opposite to each other, and the spokes 5 can be simultaneously pressed, and the bottom of the upper retainer 38 and the top of the lower retainer 47 are respectively matched with the profile of the spokes 5. The spoke 5 can be pressed by the upper mold core 36 and the lower mold core 43 through the upper retainer 38 and the lower retainer 47, so that the positioning effect of the upper mold core 36 and the lower mold core 43 is enhanced.
Besides the lower mold core 43, the lower mold 4 further comprises a supporting seat 42 and a lower mold plate 41, wherein the supporting seat 42 is fixedly arranged at the top of the lower mold plate 41, the inside of the supporting seat 42 is hollow, openings which are internally and externally communicated are formed in the top and the side edges of the supporting seat 42, the lower mold core 43 is fixedly arranged at the top of the supporting seat 42, a vertical through hole 45 is formed in the position, corresponding to the punch 35, of the top of the lower mold core 43, and the bottom of the vertical through hole 45 is communicated with the inside of the supporting seat 42. When the punch 35 is a punching punch 35 for punching the middle hole 51 and the bolt hole 52, that is, when the die is a punching die, the vertical through hole 45 can play a role in blanking, and the punched waste can fall into the cavity inside the supporting seat 42 through the vertical through hole 45 and can be cleared out through the side opening of the supporting seat 42.
As an example, as shown in fig. 6, when the punch 35 is a chamfering punch 35 for processing a chamfer at an orifice of the bolt hole 52, a female die 46 matching the punch 35 is fixedly provided inside the vertical through hole 45, and the chamfer is formed by pressing in cooperation with the female die 46. At this time, the upper die 3 further includes an upper die plate 31, a fixing plate 33, a second base plate 32, a middle hole positioning column 34 and an elastic member 37 that can stretch up and down, the punch 35 and the middle hole 51 positioning column are respectively and fixedly connected to the bottom of the fixing plate 33, the top of the fixing plate 33 is fixedly connected to the upper die plate 31 through the second base plate 32, a central positioning hole 44 that avoids the middle hole 51 positioning column descending is formed at the top of the lower die core 43, the position and the size of the middle hole 51 positioning column correspond to those of the middle hole 51 on the spoke 5, the upper die core 36 is sleeved outside the middle hole 51 positioning column and the punch 35 and can move up and down, and the top of the upper die core 36 is connected with the upper die plate 31 through the elastic member 37. Taking this as an example, the edge of the spoke 5 is placed towards the lower die 4, the positioning piece 1 is fixedly connected with the upper die 3, when the upper die 3 descends, the positioning piece 1 is driven to synchronously descend, and before the upper die 3 compresses the lower die 4, the spoke 5 can be accurately positioned under the limit influence of the positioning piece 1; when the upper die 3 presses the lower die 4, the elastic piece 37 is in a compressed state, the chamfering punch 35 presses the orifice of the bolt hole 52 to form a chamfer, the position of the chamfer is accurate, and the deviation is small; after the chamfer is formed, the upper die 3 is moved upward, and the upper die core 36 is reset by the elastic member 37. The spoke 5 after extrusion processing by the die has better quality, and the same is true when the punch 35 is a punching punch 35.
While the utility model has been particularly shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the utility model as defined by the appended claims.
