Description

Technical Field

[0001] The present application relates to the technical field of split wheel hub processing equipment, and in particular to a die pressing equipment for producing split wheel hubs. Background Art

[0002] Casters with split hubs can be mass-produced through stamping, which is different from single-piece hubs, which are made by sand casting. Since each sand casting mold can only be poured once, the casting mold will be damaged after the casting is obtained and must be reshaped, so the production efficiency of sand casting is relatively low; the split hub design gives the caster extremely high convenience, and its modular structure enables each component to be disassembled and assembled independently. Whether it is replacing worn parts or adjusting the hub configuration according to different load-bearing requirements, it can be completed easily and quickly, greatly improving maintenance efficiency and service life.

[0003] In the process of mass stamping of split wheels, how to improve the quality of stamping, how to achieve continuous and mass production of high-quality split wheels from plate materials, and how to produce split wheels that are more stable for subsequent assembly have become related technical issues that technical personnel in this field urgently need to solve. Utility Model Content

[0004] The device provides a die-casting device for producing a split wheel hub, and the specific implementation is as follows:

[0005] A die pressing device for producing a split wheel hub, comprising:

[0006] The lower die base and the suspended platform above it, the upper die pressed with the lower die base is provided at the bottom of the suspended platform through a driving cylinder, the lower die base is composed of a plurality of sub-dies connected in series, the plate-like material is transported along the length direction of the lower die base and enters each sub-die in turn in a progressive manner, the contours of the lower die base and each sub-die are respectively corresponding to realize the pressing and forming of the wheel hub;

[0007] The sub-mold includes a first mold and a second mold for processing the limiting structure required for the split wheel hub splicing, and the two molds are respectively provided with a plurality of concave and convex positions of the same number at equal intervals along the circumference, and the concave and convex positions are evenly arranged in an alternating manner along the circumference of the same circle;

[0008] The sub-mold also includes a seventh mold arranged at the end, which is a vertical through hole that conducts vertically. The seventh mold is used for vertically demolding the wheel hub from the plate-like material after molding, and there is a conveyor belt for transporting the wheel hub corresponding to the lower part of the vertical through hole.

[0009] Based on the above technical solutions, this set of die-casting equipment uses a continuous production process to carry out efficient and automated processing of plate-like raw materials, converting a complete plate into multiple split wheel hubs; a series of alternating sub-molds are used to achieve step-by-step precise forming of the split wheel hub through sequential transformation and collaborative work, ensuring the dimensional accuracy and morphological consistency of each component; in terms of process design, the first mold and the second mold are used to cooperate to stamp the concave and convex positions of the plate respectively, which not only makes the processed split wheel hub more stable during assembly and has better interlocking performance, but also means that any two split wheel hub parts have matching concave and convex structures, which can be seamlessly connected and assembled together, greatly improving production efficiency and product assembly convenience.

[0010] Preferably, the sub-mold also includes a third mold with a circular groove, and a fourth mold and a fifth mold for stretching and shaping the center of the hub. The center of the fourth mold is set as a conical table structure, and the concave end surface of the fifth mold is provided with corresponding positioning processing holes.

[0011] Based on the above technical solution, the third mold is used to process the flat plate into a cylindrical structure, and the subsequent fourth mold and fifth mold are used to process the contour of the wheel hub and open corresponding positioning holes on the wheel hub contour; it also includes a sixth mold for shaping and straightening. The sixth mold further deepens the contour of the wheel hub through the corresponding conical contour and annular protrusion, and each upper die matches the inner contour of each sub-mold.

[0013] Preferably, an inclined guide plate is installed below the other end of the conveyor belt.

[0014] Preferably, a feeder for the plate-like material is installed at the front end of the base.

[0015] Based on the above technical solutions, by configuring a feeder in the production line, the automatic and continuous feeding of plate-like materials is realized, which greatly improves the production efficiency and automation level; a conveyor belt arranged perpendicular to the base is set at the end of the equipment, and when the split wheel hub that has been pressed and demolded from the plate-like material is automatically and orderly sent out of the production line along the direction of the conveyor belt, it effectively avoids the inefficiency and safety risks that may be caused by manual handling. The entire production process forms a continuous and automated production chain from material feeding, wheel hub die molding to automatic output of finished products, which greatly optimizes the production process and improves production efficiency. At the same time, it also reduces the labor intensity of workers and ensures the stability and controllability of the production process.

[0017] Preferably, a side of the limiting column facing the plate-like material is provided with an L-shaped guide groove structure, and the peripheral side of the plate-like material abuts against each L-shaped guide groove structure.

[0018] Preferably, the upper die and each sub-die have circular outer contours of the same size, and the limiting posts are arranged outside the circular outer contours.

[0019] Based on the above technical solution, the L-shaped guide groove on the limiting column realizes the left and right limiting during the transportation of plate-like materials. At the same time, the upper die is pushed out by the hydraulic drive cylinder. The L-shaped guide groove can also support the bottom of the plate-like material during the die pressing.

[0020] By designing an L-shaped guide groove on the limit column, the integration and optimization of multiple functions are achieved; the L-shaped guide groove plays the role of left and right limit in the transportation of plate materials, ensuring that the plate materials remain stable and do not deviate during the transmission process; when the hydraulic drive cylinder pushes the upper die to perform the die pressing operation, the L-shaped guide groove is transformed into a supporting structure. When the upper die moves downward to press the plate material, the L-shaped guide groove can effectively support the side bottom of the material to prevent it from being deformed or warped due to uneven force during the pressing process, thereby ensuring the dimensional accuracy and quality stability of the final molded product.

[0021] In summary, this application includes the following beneficial technical effects:

[0022] 1. The utility model realizes the continuous production of a plurality of split wheel hubs by processing plate-like materials, and realizes the gradual forming of the split wheel hubs through a plurality of alternating sub-dies, thereby greatly improving the stamping quality;

By arranging a loading machine and a conveyor belt arranged perpendicularly to the base at the hollowed-out end portion, the plate-like material is automatically conveyed forward, and the split wheel hub is automatically transported out after being demoulded from the plate-like material;
