Description

Technical Field

[0001] This utility model belongs to the field of industrial processing, and in particular relates to a follow-up support device for hot extruded profiles. Background Technology

[0002] When hot extruding large-section irregular profiles, due to the irregularity of the cross-section, thin supports such as fins and cantilever are easily deformed by the profile's own weight during extrusion. Graphite blocks are required for extrusion support. Traditional solutions use fixed graphite supports. When the profile deforms due to abnormal or unstable online quenching, the fixed graphite causes hard deformation contact between the profile and the graphite as the profile moves along the extrusion direction, resulting in scratches, deformation, and breakage of the graphite support, which greatly reduces the yield. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the problems of the prior art and provide a hot extrusion profile discharge follow-up support device that can protect the profile from hard compression with the graphite support and reduce the occurrence of profile scratches, deformation and crushing of the graphite support.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A hot-extruded profile discharge follow-up support device includes a support plate, a movable tray is provided on the upper end surface of the support plate, and a U-shaped frame is provided on the lower end surface. The width of the support plate is greater than the width between the two side walls of the movable pallet and the width between the two open ends of the U-shaped frame. The length of the support plate is greater than the length between the two open ends of the movable pallet and the length between the two side walls of the U-shaped frame. The portions of the support plate that extend beyond the two open ends of the movable pallet and the portions that extend beyond the two side walls of the U-shaped frame at both ends are respectively formed into straight male heads.

[0005] The movable pallet is equipped with a sliding device, and the movable pallet is connected to the support plate through the sliding device.

[0006] The support plate is provided with a guide groove that runs vertically through the bottom and below the movable pallet. A guide plate is provided on the lower end surface of the movable pallet and is disposed in the guide groove.

[0007] The length of the guide groove is not greater than the length of the movable pallet, nor less than the length of the guide plate, and the guide plate can move back and forth in the guide groove under the action of external force.

[0008] The movable pallet is a U-shaped movable pallet. The sliding device includes an upper pulley with a short connecting shaft and a lower pulley with a long connecting shaft. One end of the short connecting shaft passes through the upper pulley and is connected to the outer side walls of the left and right ends of the movable pallet. The other end is connected to one end of the long connecting shaft on the lower pulley via a connecting rod.

[0009] Four sliding devices are provided, arranged in pairs symmetrically on the outer sides of the left and right ends of the movable tray.

[0010] An upper track matching the upper pulley is provided on the upper end surface of the support plate located on the outer side of both sides of the movable pallet. The upper pulley slides in the upper track. A lower track matching the lower pulley is provided on the lower end surface of the support plate located on the outer side of the two open ends of the U-shaped frame. The lower pulley slides in the lower track.

[0011] The upper and lower rails are staggered. This staggered arrangement helps to reduce the stress on the moving pulleys and connecting rods on the upper rail, reduces the risk of breakage of the connecting rods, reduces the weight, and also facilitates on-site installation.

[0012] When the movable pallet is pushed directly or indirectly by an external force, the upper pulley on the movable pallet moves along the upper track under the action of the thrust, and at the same time, it drives the lower pulley to move on the lower track. While the upper pulley and the lower pulley slide, they drive the movable pallet to move on the support plate.

[0013] The distance that the movable pallet can move on the support plate is the same as the distance that the guide plate can move within the guide groove.

[0014] Symmetrical graphite fixing screw holes are provided on the left and right side walls of the movable tray. The bolt is screwed into the graphite fixing screw hole from the outside, and after passing through the graphite fixing screw hole, it is pressed against the graphite block on the movable tray to fix the graphite block.

[0015] The beneficial effects of this utility model are as follows: In this invention, a sliding device is designed so that the graphite support can move along the extrusion direction with the profile when the online quenching is abnormal or unstable. This protects the profile from being forcibly extruded by the graphite support, reduces the occurrence of profile scratches, deformation, and crushing of the graphite support, greatly saves material costs, reduces waste, and improves the yield.

[0023] Example: Figure 1-3 As shown, A hot-extruded profile discharge follow-up support device includes a support plate 1, a U-shaped movable tray 2 is provided on the upper end surface of the support plate 1, a guide groove is provided on the support plate 1 below the movable tray 2 and runs vertically through the support plate 1, and a guide plate 3 is provided on the lower end surface of the movable tray 2 corresponding to the guide groove, the guide plate 3 is disposed in the guide groove; the length of the guide groove is not greater than the length of the movable tray 2 and not less than the length of the guide plate 3, and the guide plate 3 can move back and forth in the guide groove under the action of external force.

[0024] Symmetrical graphite fixing screw holes 4 are provided on the left and right side walls of the movable tray 2. Graphite supports are placed on the movable tray 2. Bolts are screwed into the graphite fixing screw holes 4 from the outside and then through the graphite fixing screw holes 4 to tighten the graphite supports on the movable tray 2 to fix the graphite supports.

[0025] The U-shaped frame 5 serves as a support for the support plate 1 and is set on the lower end surface of the support plate 1. It can be welded or connected using other existing fixed connection methods.

[0026] The width of the support plate 1 is greater than the width between the two side walls of the movable pallet 2, and also greater than the width between the two open ends of the U-shaped frame 5. The length of the support plate 1 is greater than the length between the two open ends of the movable pallet 2, and also greater than the length between the two side walls of the U-shaped frame 5. The portions of the support plate 1 that extend beyond the two open ends of the movable pallet 2 and the portions that extend beyond the two side walls of the U-shaped frame 5 at both ends are respectively formed into straight male heads 6.

[0027] The movable pallet 2 is equipped with a sliding device, and the movable pallet 2 is connected to the support plate 1 through the sliding device.

[0028] There are four sliding devices, which are symmetrically arranged in pairs on the outer sides of the left and right ends of the movable tray 2. Each sliding device includes an upper pulley 8 with a short connecting shaft 7 and a lower pulley 10 with a long connecting shaft 9. One end of the short connecting shaft 7 passes through the upper pulley 8 and is connected to the outer side wall of the corresponding movable tray 2. The other end is connected to one end of the long connecting shaft 9 on the lower pulley 10 through a connecting rod 11.

[0029] The upper surface of the support plate 1 located on the outer side of both sides of the movable pallet 2 is provided with an upper rail that matches the upper pulley 8. The upper pulley 8 slides in the upper rail. The lower surface of the support plate 1 located on the outer side of the two open ends of the U-shaped frame 5 is provided with a lower rail that matches the lower pulley 10. The lower pulley 10 slides in the lower rail.

[0030] The upper and lower rails are staggered. This staggered design helps to reduce the stress on the moving pulleys and connecting rod 11 on the upper rail, reduces the risk of breakage of the connecting rod 11, and reduces the weight, which also facilitates on-site installation.

[0031] When the movable pallet 2 is pushed directly or indirectly by an external force, the upper pulley 8 on the movable pallet 2 moves along the upper track under the action of the thrust. At the same time, it drives the lower pulley 10 to move on the lower track. While the upper pulley 8 and the lower pulley 10 slide, they drive the movable pallet 2 to move on the support plate 1. The distance that the movable pallet 2 can move on the support plate 1 is the distance that the guide plate 3 can move in the guide groove.

[0032] Instructions for use: Remove the rollers from the existing U-shaped frame 5 at the front beam outlet of the extruder. After removal, the two ends of the front beam U-shaped frame 5 will be exposed. The two ends of the front beam U-shaped frame 5 are "U-shaped female openings". Insert one end of the "straight male head 6" under the moving tray in this embodiment into the "U-shaped female opening". At this time, the device is fully engaged with the extruder. After the extruder mold is completed, place the graphite, which serves as the support device, into the moving tray and tighten it on both sides through the graphite fixing screw holes 4. Then, normal extrusion can begin. During the extrusion process, if the online quenching is abnormal or unstable, the profile will deform and come into contact with the graphite along the extrusion direction. However, since the graphite moves with the moving tray 2, the deformed profile will not come into hard deformation contact with the graphite. The purpose is to protect the profile from hard extrusion with the graphite support, reduce the occurrence of profile scratches, deformation, and crushing of the graphite support, greatly save material costs, reduce waste, and improve the yield.
