Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy production and processing, specifically to a disc feeding device for a continuous aluminum alloy extrusion press. Background Technology

[0002] Continuous extrusion is a metal forming technology. When the extruded billet is continuously fed into the cavity of a continuous extruder, the wheel groove bites the billet under the action of friction and pulls the metal towards the die hole. The friction generates extrusion stress near the die hole, forcing the metal to flow out of the die hole.

[0003] Continuous extrusion technology for aluminum alloys is a core process for producing high-precision profiles (such as radiators and automotive structural parts). It is widely used in aerospace, automotive structural parts, and building profiles. A rotary feeder is typically installed at the feed end of the continuous extrusion press. The coiled aluminum billet is placed on the rotary feeder and, under the traction of the continuous extrusion feed, is stably and continuously fed into the extrusion chamber, where it is formed by the continuous extrusion press. As industry demands for higher production efficiency, the structural defects of traditional feeding devices have become a key issue restricting process optimization.

[0004] Currently, mainstream rotary feeding devices suffer from the following problems: 1. Difficult and inefficient feeding: Operators need to tie the entire bundle of material with slings, lift it using an overhead crane, and then insert it into the rotary feeder before removing the slings. This process not only tests the operator's lifting skills but also results in low assembly efficiency. During assembly, the continuous extruder must remain stationary until the material is loaded, which severely impacts the efficiency of continuous extrusion. 2. In the traditional rotary feeder process, production personnel often engage in non-standard operations to improve efficiency, resulting in tilted or oblique lifting, which is detrimental to safety management. Summary of the Invention

[0005] This utility model provides a wheel feeder for a continuous aluminum alloy extrusion press, which is suitable for continuous aluminum alloy extrusion production. Before production, aluminum billet coils are pre-wound onto the feeding sleeve and neatly stacked in a fixed area for later use. When it is necessary to replace the coils to continue production, they can be quickly hoisted onto the wheel support frame by an overhead crane for replacement, which greatly improves production efficiency and reduces downtime for continuous extrusion.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] A continuous aluminum alloy extrusion press wheel feeding device includes a single-row four-point contact ball slewing bearing mounted on the frame base, which is connected to the feeding wheel by bolts. Spokes are evenly distributed on the outer end of the feeding wheel, and a support frame is set in the middle of the feeding wheel. The support frame is made of bent steel pipe and welded and fixed. A feeding sleeve can be fitted on it to replace the aluminum billet coil. The feeding sleeve is hollow, and the coil is wound around the outer circumference of the feeding sleeve. The lower end is a horizontal circular support to support the bottom of the coil.

[0008] The bottom limiting groove of the feeding sleeve matches the shape of the spokes and is fitted and positioned. The fitting and positioning of the spokes and the bottom of the sleeve can prevent relative friction between the feeding sleeve and the wheel.

[0009] The upper end of the feeding sleeve is equipped with a lifting lug. When it is necessary to replace the aluminum billet coil, the overhead crane hook can be directly hooked to the lifting lug, and the sleeve and coil can be quickly lifted and replaced by the overhead crane. The operation is quick and simple, and the operation is stable and efficient. At the same time, the overhead crane can also suspend an electronic crane scale to facilitate real-time recording of the raw material weight.

[0010] A dust cover is installed on the upper center surface of the feeding wheel to facilitate the disassembly and maintenance of the slewing bearing. This effectively prevents dust and foreign objects from directly contacting the single-row four-point contact ball slewing bearing, thus improving its service life and enhancing its aesthetic design.

[0011] Four support wheels are evenly arranged on the frame base to prevent the wheel disc from tilting when the aluminum billet wire coil is too wide or too heavy, thus improving the sensitivity and stability of the feeding wheel disc when it rotates.

[0012] The utility model is used as follows:

[0013] Before production, aluminum billet coils are hoisted or wound onto the feeding sleeve and neatly stacked in a fixed area for later use. During production, they are directly hoisted onto the feeding wheel support frame by an overhead crane, and the bottom limiting slot is fitted and positioned with the spokes. Then, the starting end of the aluminum billet coil is connected to the continuous extrusion press. The traction force generated during the continuous extrusion press production pulls the feeding wheel and slewing bearing to rotate simultaneously.

[0014] When the coil material on the sleeve is used up, the overhead crane will lift the empty sleeve directly for transfer, and then place the new sleeve carrying the new coil material onto the support frame for use in the extruder, thus achieving the effect of rapid material change.

[0015] Advantages of this utility model:

[0016] 1. This utility model is applicable to continuous extrusion production of aluminum alloys. The aluminum billet wire coil is pre-wound or sleeved on the feeding sleeve. When changing the wire coil during continuous production, the feeding sleeve can be quickly lifted and replaced by an overhead crane. Material preparation is convenient, greatly improving production efficiency and reducing downtime of continuous extrusion.

[0017] 2. The outer circumference of the feeding sleeve of this utility model is smooth, which minimizes damage to the surface of the coil blank and can effectively improve the surface quality of continuously extruded products.

[0018] 3. This utility model adopts a purely mechanized structural design, which is low in cost and easy to operate and maintain.

[0019] 4. The feeding sleeve of this utility model is equipped with lifting lugs, which makes it convenient for overhead cranes to lift and transport materials, with high operating efficiency and low safety risk; it can also be equipped with an electronic crane scale to record the weight of raw materials in real time.

[0020] 5. The frame base of this utility model has four support wheels evenly arranged, which have high sensitivity to wheel rotation and stable feeding. Attached Figure Description
