Description

Technical Field

[0001] This utility model relates to the field of hot-stamped aluminum alloy wheel hub forming with thinner spokes, and more specifically to a hot-stamped aluminum alloy wheel hub forming mechanism with thinner spokes. Background Technology

[0002] In today's rapidly developing automotive industry, lightweighting and high performance have become core pursuits in automotive design and manufacturing. Aluminum alloy wheels, with their significant advantages of light weight, high strength, and corrosion resistance, are increasingly widely used in the automotive parts sector. As a key load-bearing and structural component of aluminum alloy wheels, the wheel spokes directly determine the overall performance and safety of the wheel. The thinning hot stamping process for wheel spokes has gradually become one of the mainstream wheel spoke forming processes because it effectively achieves lightweight wheel spoke design, improves material utilization, and enhances structural strength. However, in the existing stamping process for aluminum alloy wheels, it is not suitable for positioning and clamping the raw metal sheet during stamping. Therefore, this application is proposed to solve the aforementioned technical problems. Utility Model Content

Detailed Implementation

[0011] A spoke-thinning hot stamping aluminum alloy wheel hub forming mechanism includes a support frame 101 and a base 102 fixedly connected to the bottom of the support frame 101. A forming frame 103 is fixedly connected to the base 102. A sliding seat 104 is fixedly connected to the top of the support frame 101. A lifting seat 201 is slidably connected to the sliding seat 104. A stamping seat 202 is fixedly connected to the bottom of the lifting seat 201. A side plate 105 is fixedly connected to each side of the bottom of the support frame 101. A retaining mechanism is slidably connected to each side plate 105.

[0012] This section is based on Figure 1-6The embodiment described herein is as follows: During the hot stamping of a spoke-thinning aluminum alloy wheel hub, to facilitate the positioning and clamping of the raw material metal sheet during stamping and prevent deformation caused by displacement of the raw material metal sheet during stamping, the heated aluminum alloy metal sheet is horizontally placed at the top opening of the stamping seat 202. At this time, the lifting seat 201 slides downwards, aligning the stamping seat 202, located in the middle of the lifting seat 201, with the raw material metal sheet placed at the top opening of the stamping seat 202. Further pressing causes the stamping seat 202 to press the raw material metal sheet into the forming frame 103. Then, with the cooperation of the stamping seat 202 and the forming frame 103, the raw material metal sheet is stamped into the shape of a wheel hub. Before stamping... To prevent stamping deviation, the fixing mechanism, which is slidably connected to the side plates 105 on both sides of the bottom of the support frame 101, clamps and limits the raw metal sheet from the left and right sides of the forming frame 103. This ensures that the center of the raw metal sheet is aligned with the center of the forming frame 103. After positioning, the clamping of the raw metal sheet is released when the bottom surface of the stamping seat 202 is attached to the raw metal sheet. Then, the positioned raw metal sheet is stamped, thereby improving the accuracy of the stamping process and preventing the position of the raw metal sheet from shifting during the stamping process. Furthermore, it facilitates the positioning and clamping of the raw metal sheet during the stamping process, preventing the raw metal sheet from shifting during the stamping process and causing deformation.

[0013] The forming frame 103 is fitted with the stamping base 202. The front and rear sides of the sliding base 104 are polished. The movable end of the hydraulic cylinder 203 is fixedly connected to the middle of the stamping base 202, and the fixed end of the hydraulic cylinder 203 is fixedly connected to the middle of the sliding base 104. This part is based on... Figure 1-6 The embodiment described herein is as follows: when controlling the lifting seat 201 to lift, the hydraulic cylinder 203 is driven to make the lifting seat 201 located on the movable end of the hydraulic cylinder 203 slide on the sliding seat 104, thereby controlling the lifting seat 201 to lift, so that the stamping seat 202 is fitted onto the forming frame 103 to stamp and form the raw material metal plate.

[0014] The lifting seat 201 has an elongated hole on each of its front and rear sides that is slidably connected to the front and rear sides of the sliding seat 104.

[0015] The fixing mechanism includes a right-angle seat 301 and an arc-shaped piece 302 fixedly connected to the middle of the upper side of the right-angle seat 301. A pressing piece 303 is slidably connected to the top of the right-angle seat 301. The movable end of an electric push rod II 307 is fixedly connected to the left side of the pressing piece 303. The fixed end of the electric push rod II 307 is fixedly connected to the top of the right-angle seat 301.

[0016] The pressing plate 303 and the arc-shaped plate 302 are designed to work together, both being arc-shaped strips.

[0017] Multiple vertical grooves are provided on the adjacent surfaces of the pressing plate 303 and the arc-shaped plate 302.

[0018] The bottom left side of each of the two right-angle seats 301 is fixedly connected to the movable end of an electric push rod I 306, and the fixed ends of the two electric push rods I 306 are fixedly connected to the outside of the two side plates 105.

[0019] Each right-angle seat 301 has a side arc plate 304 fixedly connected to its front and rear sides, and an arc-shaped limiting seat 305 fixedly connected to each side arc plate 304. Each limiting seat 305 has a groove in the middle.

[0020] This section is based on Figure 1-6 The embodiment described herein is as follows: When the raw material metal sheet is placed on the forming frame 103 and clamped and positioned, the electric push rods I 306 on both sides are driven, and the right-angle seats 301 located on the movable end of each electric push rod I 306 move towards the center. Then, the front and rear positions of the raw material metal sheet are respectively inserted into the two limiting seats 305 on the front and rear sides of the right-angle seats 301, so that the raw material metal sheet can fit against the central groove of each limiting seat 305. At this time, each electric push rod II 307 is driven to move the corresponding pressing piece 303 downward to press the circular metal sheet onto each arc-shaped piece 302, and the vertical groove on the pressing surface of the arc-shaped piece 302 and the pressing piece 303 on the adjacent side raises the clamped and pressed raw material metal sheet. The friction between them improves the pressing stability. When the hydraulic cylinder 203 drives the stamping seat 202 to simultaneously stamp the raw material metal sheet, the two electric push rods I 306 are driven simultaneously to release the raw material from the clamping position on both sides by the pressing plate 303. The limiting seat 305 in the circumferential direction provides a limit on the raw material. During stamping, the edge will lift up, and the groove in each limiting seat 305 provides a certain amount of movement space without hindering the limiting of the raw material. When the raw material will not shift due to the stamping when it has been stamped to a certain extent, the electric push rods I 306 on both sides are driven to retract the right angle seat 301 to its original position, which ensures that the position of the raw material metal sheet will not affect the stamping work.
