Description

Technical Field

[0001] This utility model relates to the field of double-flanged wheel manufacturing technology, specifically to a rolling equipment for manufacturing crane wheels. Background Technology

[0002] Currently, in the manufacturing process of crane wheels, the rolling of the base material typically requires multiple core processes, including pressing, forming, and punching, each of which often relies on independent rolling equipment or specialized die assemblies. For example, the base material first needs to be pre-shaped in a specialized pressing device, pressing the original metal billet into a disc-shaped structure that meets the dimensional requirements of subsequent processing. After pressing, the disc-shaped base material needs to be transferred to the forming equipment via a transfer device, where a forming die is used to pre-shape the wheel profile. After the forming process is completed, the base material is transferred to the punching equipment, where a punching die is used to machine the shaft holes for assembly at preset positions on the base material. However, the aforementioned traditional processing mode has significant technical drawbacks: on the one hand, multiple processes rely on independent equipment, resulting in cumbersome transfer of the substrate between different machines. This not only increases labor costs and transfer time but also makes the substrate processing accuracy susceptible to issues such as positioning deviations and collisions during transfer, potentially even leading to substrate scrap. On the other hand, the independent design of the die components in each machine prevents them from working collaboratively, creating significant interruptions in the entire rolling process and resulting in extremely poor operational continuity. In mass production scenarios, this interrupted processing mode leads to low overall equipment efficiency, making it difficult to meet the demands of large-scale, high-efficiency crane wheel production. Furthermore, while some existing technologies attempt to improve operational continuity through integrated design, most can only achieve simple integration of two processes (such as pressing and forming), still requiring separate punching operations. This fails to achieve full-process integration of the three core processes: pressing, forming, and punching. At the same time, the pressing mold components of existing integrated equipment mostly adopt fixed structures, making it difficult to flexibly adjust according to the processing requirements of different specifications of crane wheels. The equipment has poor versatility, and when it is necessary to switch processing specifications, the entire pressing mold component must be disassembled and replaced, further increasing the operation time and complexity, and restricting the improvement of production efficiency.

[0013] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0014] like Figure 1-4 As shown, the rolling equipment for manufacturing crane wheels in this embodiment uses the frame 1 as the load-bearing frame. The upper lifting platform 3 drives the pressure head 2 to move downward for stamping, and the lower transfer module is responsible for the transfer of workpieces between the various stations of the pressing die assembly. The pressing die assembly is arranged along the movable slide 4 with the pressing station 5, forming station 6, and punching station 7 in sequence. The lifting platform 3 is also equipped with a rotatable robotic arm 23 to drive the stamping bar 8, realizing the integrated process of "pressing → forming → punching".

[0015] Pressing station 5: The blank is initially flattened to prepare for subsequent forming.

[0016] Forming station 6: The base 16 supports the lower forming mold 17, the central groove 18 corresponds to the gap 15 of the pressure head 2, and the surrounding area is equipped with a barrier 19 to ensure forming accuracy and prevent displacement.

[0017] Punching station 7: A load-bearing plate 21 is installed above the storage bin 20, with a through hole 22 in the middle; the stamping bar 8 punches the formed parts through the through hole 22, and the waste falls into the storage bin for centralized processing.

[0018] The lifting platform 3 drives the pressing head 2 to move vertically, providing pressing power; the stamping bar 8 is installed on the lifting platform 3 through the mechanical arm 23 and the rotating seat 24, and its angle and position can be adjusted to avoid collisions with other positions during the pressing and forming stages.

[0019] The movable slide table 4 is equipped with clamps 9 on both sides and a telescopic rod 10 on the outside; the frame 1 is equipped with a lifting seat 11 connected to the telescopic rod 10, and the workpiece is gripped, transferred and positioned between various workstations through lifting and telescopic actions.

[0020] Press head 2: The base 12 is connected to the lifting platform 3; a pre-pressing protrusion 13 is provided in the center of the lower surface, and the surrounding area is a ring-shaped pre-pressing block 14, with a gap 15 reserved between them. It cooperates with the lower mold groove 18 at the forming station to achieve step-by-step pre-pressing and precise forming.

[0021] Stamping bar 8: The upper part is mounted on the lifting platform 3 by the robotic arm 23 and the rotating seat 24, which can operate at multiple angles to meet the needs of punching and other processes.

[0022] The work sequence is as follows: First, the movable slide table 4 slides so that the pressing station 5 is located below the pressing head 2. The heated cylindrical substrate is placed at the pressing station 5 for pressing. The height of the cylindrical substrate is compressed to the range that matches the wheel height. Then, the clamp 9 is used to pick up the compressed material. The movable slide table 4 moves backward so that the material falls into the forming station. Then, the pressing head 2 is used for forming and rolling to obtain a rough blank. After the forming operation is completed, the clamp 9 and the movable slide table 4 repeat the above operation to transfer the rough blank to the punching station 7. The rotating seat 24 rotates the stamping bar 8 to the working position. The lifting table 3 drives the stamping bar 8 to press down and complete the punching operation on the rough blank.
