Description

Technical Field

[0001] The utility model relates to the field of wheel hub forging demoulding, in particular to a hole enlarging and skin cutting die for H-shaped forged wheel hub forgings. Background Art

[0002] There are many wheel hub shapes currently in use. One-piece, two-piece, U-shaped and H-shaped are commonly used wheel hub shapes. We can produce many wheel hub shapes through forging. During the forging process, the forging needs to be expanded and the skin removed in order to perform the rim spinning process on the forging.

[0003] However, when expanding and cutting the H-shaped wheel hub, the forgings are often adsorbed on the mold and difficult to demold, which sometimes causes downtime and serious economic losses. It is necessary to spray a large amount of mold release agent on the mold to increase lubrication, which increases the cost. This patent designs a mold with a spring and a bottom ejector, which can easily demold the forgings without spraying mold release agent, saving costs and protecting the environment.

[0004] Therefore, in view of the above problems, a die for expanding and cutting the hole of H-shaped forged wheel hub forgings is proposed to solve the above problems. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model develops a die for expanding and cutting holes of H-shaped forged wheel hub forgings. The utility model saves demoulding time, eliminates the need for spraying a demoulding agent, and saves costs.

[0007] The lower support assembly includes a support member, a lower template, a punch, a guide column, a material ejection tray and a push rod. The support member is arranged on the lower template, the guide column is slidably arranged in the support member, the material ejection tray is arranged on the top of the guide column, the bottom of the guide column is connected to the push rod through a connecting plate, the push rod is arranged at the bottom of the lower template, and the output end of the push rod passes through the lower template;

[0008] The upper ejector assembly is located above the lower support assembly, and the upper ejector assembly includes a forging press slider, a punch, an upper die and an ejector unit.

[0010] As an optimization, a movable hole for placing the ejecting unit is opened at the bottom of the upper mold. The ejecting unit includes a fixing bolt, a ejecting spring and a ejecting disc. One end of the ejecting spring is connected to the top of the inner wall of the movable hole, and the other end is connected to the ejecting disc. The top of the inner wall of the movable hole is connected to the top of the fixing bolt. The fixing bolt is located in the ejecting spring. The bottom of the fixing bolt passes through the ejecting disc. When the ejecting spring is in a naturally extended state, the ejecting disc is driven to extend out of the movable hole.

[0011] As an optimization, the upper die and the forging press slide are detachably connected by bolts.

[0012] As an optimization, the support member includes a lower mold, a second connecting plate and a support seat. The bottom of the support seat is arranged on the lower mold plate.

[0021] like Figure 1 to Figure 2 As shown, a die for expanding and cutting holes of H-shaped forged wheel hub forgings comprises an upper ejector assembly, a lower support assembly and a material storage box 11;

[0022] The lower support assembly includes a support member, a lower template 10, a punch 6, a guide column 14, a material ejection plate 15 and a push rod 12. The support member is arranged on the lower template 10, the guide column 14 is slidably arranged in the support member, the material ejection plate 15 is arranged on the top of the guide column 14, the bottom of the guide column 14 is connected to the push rod 12 through a connecting plate 13, the push rod 12 is arranged at the bottom of the lower template 10, and the output end of the push rod 12 passes through the lower template 10;

[0023] The upper ejector assembly is located above the lower support assembly, and the upper ejector assembly includes a forging press slider 1, a punch 6, an upper die 2 and an ejector unit. The forging press slider 1 is slidably arranged on the guide rail of the forging press, and the upper die 2 is arranged on the forging press slider 1. The upper die 2 is arranged at one end away from the forging press slider 1, and a punch 6 and two ejector units for forgings to be separated from the die are arranged. The punch 6 is located between the two ejector units, and the punch 6 can directly cut off the skin;

[0024] The material storage box 11 is arranged at the bottom of the lower support assembly.

[0025] By providing a push-up unit, the forging can be separated from the die, saving time. By providing a guide column 14 to drive the push-up plate 15 to push up the forging, spraying a release agent is omitted, saving costs.

[0026] In this embodiment, a movable hole 17 for placing a material ejection unit is provided at the bottom of the upper die 2. The material ejection unit includes a fixing bolt 3, a material ejection spring 4 and a material ejection disc 5.

The top of the inner wall of the movable hole 17 is connected to the top of the fixing bolt 3. The fixing bolt 3 is located in the material ejection spring 4. The bottom of the fixing bolt 3 passes through the material ejection disc 5. When the material ejection spring 4 is in a naturally extended state, it drives the material ejection disc 5 to extend out of the movable hole 17. When the upper die 2 rises, the material ejection spring 4 changes from a contracted state to an extended state. At this time, a certain elastic force will be applied to the material ejection disc 5 so that the material ejection disc 5 extends out of the movable hole 17, so that the forging is separated from the die, which saves the time of using a cylinder to punch the material in the past.

[0027] In this embodiment, the upper die 2 is detachably connected to the forging machine slide block 1 by bolts.

[0028] In this embodiment, the support member includes a lower mold 7, a connecting plate 8 and a support seat 9. The bottom of the support seat 9 is set on the lower mold plate 10. The top of the support seat 9 is detachably connected to the lower mold 7 through the connecting plate 8. The guide column 14 moves through the support seat 9, the connecting plate 8 and the lower mold 7 in sequence and is connected to the top material plate 15.

[0029] The lower support assembly is provided with a blocking slide plate 16, which is tilted, with the top of the blocking slide plate 16 close to the casting, and the bottom close to the storage box 11. The cut skin enters the storage box 11 through the blocking slide plate 16, eliminating the trouble of manual picking.

[0030] Although the specific implementation methods of the utility model are described above in conjunction with the accompanying drawings, this does not limit the scope of protection of the utility model. On the basis of the technical solution of the utility model, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the utility model.
