Description

Technical Field

[0001] This utility model relates to the field of aluminum processing technology, specifically to a feeding device for an aluminum rod extrusion machine. Background Technology

[0002] Aluminum bar feeding is a key pre-processing step in aluminum extrusion, mainly including three stages: raw material preparation, heat treatment, and automatic feeding. Modern production lines generally adopt automated feeding systems, which use robotic arms or conveyor belts to accurately transport aluminum bars. The feeding speed must be matched with the working rhythm of the extruder. The system is equipped with infrared safety protection devices, and operators must wear professional protective equipment. The key points of quality control include the detection of aluminum bar temperature uniformity and the control of feeding positioning accuracy.

[0003] In existing aluminum bar extrusion presses, aluminum bars are typically placed next to a feeding device using a forklift. The feeding device then lifts the aluminum bars and transfers them to the extrusion press. However, when a large number of aluminum bars are piled up next to the feeding device, the feeding device needs to withstand a large force to lift a single aluminum bar and transfer it to the extrusion press. Over time, this will shorten the lifespan of the feeding device, and the loading load on the feeding device when lifting the aluminum bars will be relatively large. Utility Model Content

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Example 1

[0032] Please see Figures 1-2 A feeding device for an aluminum rod extrusion mill, comprising:

[0033] The lifting box 1 and the transmission rod 2 are installed at one end of the lifting box 1.

[0034] The first chain 3 is rotatably connected to the inside of the lifting box 1;

[0035] Two protruding plates 4 are installed at one end of the first chain 3. A short shaft 6 is installed between the two protruding plates 4. A sleeve 5 is installed on the outer surface of the short shaft 6. A lifting bar 8 is installed at one end of the sleeve 5. The lifting bar 8 is used to lift the aluminum rod upward and move it.

[0036] The baffle 7 is installed at one end of the protruding plate 4, and one end of the sleeve 5 is used to abut against the baffle 7.

[0037] Square groove 12 is set at the upper end of lifting box 1, and lifting bar 8 is slidably connected to square groove 12;

[0038] Insert plate 15 is installed inside the lifting box 1. Insert plate 15 is used to slide upward through the square groove 12 and the upper end of insert plate 15 is used to press between two aluminum rods.

[0039] Its transmission rod 2 is inclined at one end of the lifting box 1, and the axis of the transmission rod 2 is inclined to the axis of the lifting box 1, so that a large number of aluminum rods can roll by themselves.

[0040] according to Figure 1 and Figure 2 As shown, a large number of aluminum rods are placed on the upper end of the transmission rod 2. The first chain 3 drives the sleeve 5 and the lifting bar 8 to slide upward, thereby using the lifting bar 8 to drive the aluminum rods to slide upward and approach the extruder to complete the feeding.

[0041] Furthermore, by setting an insert plate 15 inside the lifting box 1, when the first chain 3 drives the lifting bar 8 to slide upward, the insert plate 15 slides upward, causing the two aluminum bars to separate at intervals. This ensures that the lifting bar 8 only drives one aluminum bar to slide upward, and the blocking effect of the insert plate 15 prevents the other aluminum bars from contacting the aluminum bars at the upper end of the lifting bar 8. This reduces the load on the first chain 3 that drives the lifting bar 8 to lift upward and improves its service life.

[0042] Furthermore, since the aluminum rods have different diameters, in order for the lifting bar 8 to just drive the aluminum rods upward without touching the adjacent aluminum rods, the length of the lifting bar 8 is the same as the diameter of the aluminum rods. Therefore, the lifting bar 8 is snapped into the inside of the sleeve 5 and fixed by screws.

[0043] Example 2

[0044] This embodiment is an improvement upon embodiment 1. For details, please refer to [link / reference]. Figures 1-3 The inside of the lifting box 1 is equipped with a vertical bar 9, which is used to squeeze one end of the sleeve 5 to swing downward.

[0045] A torque spring is also installed on the outer surface of the short shaft 6, and the extension plate 4 and the sleeve 5 are connected by the torque spring.

[0046] according to Figure 2 and Figure 3 When the lifting bar 8 drives the aluminum rod to slide upward, the vertical bar 9 abuts against one end of the sleeve 5, so that the sleeve 5 uses the short shaft 6 as a fulcrum, causing one end of the lifting bar 8 to tilt upward, causing the lifting bar 8 to drive the aluminum rod to tilt to one side, and then the aluminum rod slides to the upper end of the lifting box 1. Then, by rotating the second chain 10, the second chain 10 drives the push plate 11 to slide, and the push plate 11 pushes the aluminum rod to slide, thus realizing fully automatic feeding.

[0047] Example 3

[0048] This embodiment is an improvement upon embodiment 2. For details, please refer to [link / reference]. Figures 1-4 The inside of the lifting box 1 is equipped with a telescopic column 13, and an adjustment plate 14 is installed at the upper end of the telescopic column 13. A plug plate 15 is installed at the upper end of the adjustment plate 14.

[0049] The upper end of the adjustment plate 14 is provided with several round holes 16, and a pin is installed inside the round holes 16.

[0050] The pin is used to pass through the round hole 16 and the insert plate 15.

[0051] according to Figure 3 and Figure 4 As shown, the lifting bar 8 can be selected according to the diameter of the aluminum rod. Therefore, in order to allow the insert plate 15 to be inserted between two aluminum rods, the insert plate 15 is slidably connected to the upper end of the adjusting plate 14 to adjust the position of the insert plate 15. Then, the insert plate 15 is fixed by the pin, so that the insert plate 15 can be inserted between aluminum rods of any diameter.

[0052] It should be noted that its telescopic column 13 includes a cylinder, a rod and a return spring. The upper end of the cylinder is connected to the lower end of the connecting frame 3. The rod is slidably connected inside the cylinder, and the cylinder and the rod are connected by a return spring.

[0053] The return spring drives the round rod to slide upward, which in turn drives the adjustment plate 14 to slide upward. The adjustment plate 14 then drives the insert plate 15 to be inserted between the two aluminum rods.

[0054] Example 4

[0055] This embodiment is an improvement upon embodiment 3. For details, please refer to [link / reference]. Figures 1-4 One end of the first chain 3 is also equipped with a sleeve tube 17, and a connecting strip 19 is slidably connected inside the sleeve tube 17. The connecting strip 19 and the sleeve tube 17 are connected by a return spring 18.

[0056] A pressing plate 20 is installed at the lower end of the connecting strip 19, and the pressing plate 20 is used to abut against the adjusting plate 14;

[0057] The lower end of the connecting bar 19 is rotatably connected to a short rod shaft 21, one end of which is connected to one end of the extrusion plate 20;

[0058] A torque spring 22 is also installed on the outer surface of the short rod shaft 21, and the connecting bar 19 is connected to the short rod shaft 21 through the torque spring 22;

[0059] It also includes a second chain 10, which is rotatably connected to the upper end of the lifting box 1. A push plate 11 is installed at one end of the second chain 10, which is used to push the aluminum rod to slide.

[0060] according to Figure 3 and Figure 4 As shown, firstly, the first chain 3 drives the sleeve tube 17 and the extrusion plate 20 to abut against the adjusting plate 14, thereby causing the adjusting plate 14 to compress the round rod and the support spring, so that the insert plate 15 no longer abuts against the aluminum rod, and then the aluminum rod slides against the lifting box 1. Then, when the first chain 3 drives the sleeve tube 17 to slide upward, the connecting bar 19 drives the extrusion plate 20 to slide upward. At this time, the lifting bar 8 has not yet contacted the aluminum rod. Then, when a gap is created between the sleeve tube 17 and the extrusion plate 20, the support spring pushes the round rod and the adjusting plate 14 to slide upward, thereby causing the adjusting plate 14 to drive the insert plate 15 to insert between the two aluminum rods, thus achieving the separation of aluminum rods.

[0061] It should be noted that the spring force of its supporting spring is greater than the gravity generated by the downward pressing of the aluminum rod on the lifting box 1.

[0062] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0063] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
