Description

Technical Field

[0001] The utility model relates to the technical field of aluminum alloy processing equipment, in particular to a rice heavy aluminum alloy export guide tool. Background Art

[0002] When processing heavy aluminum alloy, in order to ensure the straightness of the profile and prevent hard bending in the vertical extrusion direction, it is necessary to set a set of exit guide tooling between the extrusion die and the extrusion raceway to guide the profile extruded from the extrusion die to the extrusion raceway.

[0003] At present, different special export-guided tooling is required for rice-heavy aluminum alloys of different sizes. It is not only very troublesome to replace during production switching, which seriously affects production efficiency, but also brings greater financial investment pressure. The storage of multiple sets of tooling will also take up a large factory space and is very troublesome to manage.

[0004] Solving the above problems has become a top priority. Utility Model Content

[0008] By adopting the above-mentioned heavy-weight aluminum alloy export guide tooling, the height of the feed end of the guide plate can be adaptively adjusted according to the outer dimensions of the extruded profile, thereby providing reliable support for the profile. At the same time, the positions of the two guide rollers can be adaptively adjusted according to the outer dimensions of the extruded profile, thereby accurately guiding the profile to the extrusion raceway, and at the same time preventing the profile from falling due to its own weight and colliding with the first conveying roller of the extrusion raceway, thereby causing hard bending in the vertical extrusion direction. Therefore, the heavy-weight aluminum alloy export guide tooling has excellent versatility. Not only does it not need to be replaced during production switching, but only the above-mentioned two-step adjustment is required to stably and reliably guide the extruded profile to the extrusion raceway, thereby ensuring the straightness of the profile and improving production efficiency. Moreover, it is no longer necessary to prepare multiple sets of export guide tooling, thereby alleviating the pressure of capital investment and the trouble of tooling management, and also reducing the occupancy of factory storage space.

[0020] The utility model is further described below in conjunction with embodiments and drawings.

[0021] like Figure 1 As shown, a rice-heavy aluminum alloy outlet guide tooling mainly includes a guide plate 3 and a guide device 4 sequentially arranged between an outlet die 1 and an extrusion raceway 5. Among them, the outlet die 1 includes an outlet ring 11 and a support ring 12, and the support ring 12 has a profile through hole 121 connected to the profile outlet 111 of the outlet ring 11. The profile 2 passes through the profile through hole 121 after being extruded from the profile outlet 111 of the outlet die 1.

[0022] At this time, the feeding end of the guide plate 3 extends to the profile outlet 111, and can be supported on the bottom wall of the profile through-hole 121 by at least one set of lifting and adjusting components 6. By adjusting the lifting and adjusting components 6, the bottom of the profile 2 is supported on the guide plate 3 without bending downward, thereby ensuring the stability and reliability of the profile 2 discharge.

[0023] Specifically, see Figure 2 and Figure 3The lifting and lowering adjustment component 6 includes a support frame 61, a nut 62 and a support and adjustment bolt 63 matched with the nut 62, wherein the support frame 61 is vertically installed at the bottom of the guide plate 3, the nut 62 is fixedly installed at the bottom of the support frame 61, the screw rod of the support and adjustment bolt 63 is threadedly fitted and vertically penetrated on the nut 62, and the nut of the support and adjustment bolt 63 is located at the lower end of the screw rod, that is, the screw rod of the support and adjustment bolt 63 passes through the support frame 61 downward, and the nut at the lower end of the screw rod of the support and adjustment bolt 63 is supported on the bottom wall of the profile through hole 121.

[0024] By using a wrench, rotating the nut of the support adjusting bolt 63 in one direction, the support frame 61 can lift the guide plate 3 upward. Conversely, rotating the nut of the support adjusting bolt 63 in the other direction can cause the support frame 61 to drive the lifted guide plate 3 downward. This is simple and reliable.

[0025] It should be pointed out that the present embodiment preferably adopts at least two lifting and adjusting components 6, wherein two lifting and adjusting components 6 are relatively arranged on both sides of the guide plate 3 in the width direction, and the remaining lifting and adjusting components 6 are evenly distributed between the above two lifting and adjusting components 6, thereby ensuring the stability of the guide plate 3 and improving the reliability of supporting the profile 2.
