Problems solved by technology

[0002] Since the existing forging wheel mold can only punch a single center straight hole of the blank, the metal in the blank’s inclined window needs to be processed by machining, which brings troubles in the follow-up process, increases the production cycle and increases the cost.
Whether it can be realized in the very small space of the wheel, and the oblique window of the hub blank can be punched at the same time has become a very difficult issue.
The invention patent with the publication number CN104722694A discloses a forging wheel composite die, which can complete the tasks of punching the center hole, punching the inclined window, and rim reaming at one time, which can reduce the subsequent processing time and unnecessary processes of the wheel blank. The production cycle of the wheel is shortened, and the time occupied by equipment and manpower is reduced. However, this mold cannot forge wheel blanks that do not require rim reaming. The pressure surface of the upper mold is not flat, and it is easy to cause deformation of the forming surface under positive pressure. The pressure of the inclined hole of the window oblique punch is not large, which may easily cause problems such as unsmooth hole and inconsistent operation of the punch. In addition, the demoulding structure of the mold only uses the spring force to demould, and the demoulding ability is limited, which is not conducive to simultaneous demoulding

Embodiment 1

[0024]A compound mold for forging oblique window holes, including an upper mold base 2, a connecting sleeve 1, an upper mold sliding sleeve 3, a pressure plate 4, a window oblique punch 5, a central punch 17, a first connecting screw 15, and a first spring 14 , the second connecting screw 19, the second spring 18, two left and right hydraulic auxiliary systems, the lower mold 6, the base plate 9, the tray 7, the lower supporting plate 8, the ejector rod 10, the guide post 11, the waste slide plate 12, the bolt 16, The upper mold base 2 includes a circular top surface and a side wall extending downward around the top surface, and the side wall has a certain thickness; the connecting sleeve 1 is a columnar structure, and the connecting sleeve 1 is fixedly connected to the top surface of the upper mold base 2 by bolts 16. The bottom; the pressing plate 4 is a columnar structure, and the bottom surface of the pressing plate 4 is a plane; the central punch 17 is arranged in the conn...

Embodiment 2

[0031] In the compound mold for forging oblique window holes provided in this embodiment, the wheel hub blank needs to punch six oblique window holes, and a hydraulic auxiliary system is used, combined with the attached image 3 As shown in , one of the main piston rods in the hydraulic auxiliary system drives the six distribution piston rods of the six sub-hydraulic cylinders to move up and down the six window oblique punches 5 through the hydraulic power of the hydraulic oil. Wherein said lower mold 6 is hollow, and is divided into upper and lower two parts, and upper part diameter is small, and lower part diameter is big; Described lower mold 6 circumference is evenly provided with 3 square empty slots, and lower supporting plate 8 is arranged on the bottom plate, The lower supporting plate 8 is located in the lower space of the lower mold 6, and the circumference of the lower supporting plate 8 is fixedly provided with a guide post 11 at a position corresponding to the squa...

Abstract

The invention belongs to the technical field of forging dies, and particularly relates to a forging and inclined window hole punching composited die. The composite die comprises an upper die seat, a connecting sleeve, an upper die sliding sleeve, a pressing plate, a window inclined punch, a central punch, a first connecting screw, a first spring, a second connecting screw, a second spring, a hydraulic auxiliary system, a lower de and a bottom plate. The bottom surface of the pressing plate of the composite die is a plane, so that deformation of the front forming surface is avoided; meanwhile,hydraulic power is added to the window inclined punch, the pressure for inclined hole punching is increased, and the quality problem is avoided; besides, the demolding force is increased, by the aid of a multi-split synchronous hydraulic device, synchronization of multiple window inclined punches can be well realized, simultaneous demolding of the punches can be realized, the processes of punchingof hub blank inclined windows and separation from the window inclined punches are performed simultaneously in the very small space of a wheel, and the structure is ingenious.
