Description

Technical Field

[0001] The invention relates to the technical field of aluminum profile extrusion discharge, in particular to a directional discharge structure applied to an aluminum profile extrusion process. Background Art

[0002] The principle of aluminum profile extrusion is based on the plastic deformation characteristics of metal. The aluminum bar billet heated to the appropriate temperature is placed in the extrusion barrel, and the extrusion rod of the extruder is used to apply strong pressure to cause the aluminum bar to undergo plastic deformation. Due to the limitation of the die hole, the aluminum metal can only be extruded from the die hole to form an aluminum profile of corresponding shape and size.

[0003] The entire process is divided into the feeding stage, in which the aluminum profile is stably and evenly fed from the hopper to the extruder inlet via the feeding screw shaft. In the extrusion stage, the aluminum profile is pushed by the main shaft and pressurized by the pressure cylinder to produce plastic deformation and be extruded from the die hole. In the forming stage, the extruded aluminum profile is cut by the cutting machine and processed by the forming die.

[0004] When heated aluminum rods are extruded under high temperature and high pressure, the resistance encountered by the molten aluminum during the flow process is uneven due to the complex flow channel structure inside the mold. This directly causes the stress inside the aluminum profile to be complex and unevenly distributed. In this case, the aluminum profile is very prone to bending and deformation, and it is difficult to ensure its straightness and stability. In addition, in the entire process from aluminum profile extrusion from the mold to cooling and forming, there is a lack of a precise and continuous constraint mechanism, which cannot solve the continuous changes in its internal stress, resulting in uneven product quality. Summary of the Invention

[0005] The object of the present invention is to provide a directional discharge structure applied to an aluminum profile extrusion process, so as to solve the problems mentioned in the above background technology.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a directional discharge structure for aluminum profile extrusion process, comprising an equipment base plate and an extruder on top thereof, a long-distance material receiving support plate fixedly mounted on the top of the equipment base plate, and one end of the long-distance material receiving support plate extending to the material outlet of the extruder, and a follower stop assembly and two support seats are provided on the top of the equipment base plate and on both sides of the long-distance material receiving support plate;

[0007] The follow-up positioning assembly includes multiple groups of positioning cylinders and a corresponding number of positioning rods. The positioning rods are slidably connected to the interior of the positioning cylinders, and one end of the positioning rod located outside the positioning cylinder is fixedly connected to a positioning auxiliary plate.

[0008] Furthermore, a limiting groove is provided on the outer side of the positioning cylinder, a guide linkage block is fixedly connected to the outer side of the positioning rod, and the guide linkage block is slidably connected in the limiting groove, and a cylindrical slider is fixedly connected to the end of the positioning cylinder away from the positioning auxiliary plate.

[0009] Furthermore, a positioning track frame is fixedly connected to the top of the support seat, and the positioning track frame is composed of two long straight frames and two semicircular frames. The inner walls of the two semicircular frames are provided with semicircular grooves with the same outer contour shape. The inner wall of one of the long straight frames is provided with a long straight groove 1 connected to the two semicircular grooves end to end, and the inner wall of the other long straight frame is provided with a positioning groove connected to the two semicircular grooves end to end. The positioning groove is composed of two symmetrically arranged oblique grooves and a long straight groove 2, and the two ends of the long straight groove 2 are connected to the two oblique grooves, and the two oblique grooves are respectively connected to the two semicircular grooves.

[0010] Furthermore, transmission chain plates that rotate coaxially are installed on the top of the equipment base plate and on both sides of the long-distance material receiving plate. The outer sides of the transmission chain plates are fixedly connected to the outer wall of the positioning cylinder through pads arranged at equal intervals.

[0011] Furthermore, one end of the positioning track frame is fixedly connected to a closed frame, an inner side wall of the closed frame is provided with a sliding groove having the same shape as the outer contour of the closed frame, and the cylindrical slider is slidably connected in the sliding groove.

[0012] Furthermore, the top of the equipment base plate is fixedly connected to a frame, and one side of the frame is fixedly connected to a supporting plate, a lifting push rod is fixedly installed on the top of the supporting plate, and a cover shell fixed to the bottom end of the lifting push rod is provided below the supporting plate, and the bottom of the cover shell is movably connected to multiple groups of tightening rollers through bearings.

[0013] Furthermore, partitions are installed on the top of the bottom plate of the equipment and on both sides of the long-distance material receiving support plate, and a spring is provided inside the positioning cylinder to connect the end of the positioning rod and the inner wall of the positioning cylinder.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. When the present invention is in use, after the heated aluminum rod is extruded by the hydraulic cylinder, the lifting push rod is used to drive the holding roller to suppress the "warping" of the aluminum profile. The guide linkage block moves in a direction under the action of the transmission chain plate, prompting the holding auxiliary plate to regularly extend or retract. The guide linkage block enters the second long straight groove, driving the holding auxiliary plate to move synchronously with the aluminum profile at a constant pressure, forming an efficient "mobile clamp" effect, which can not only constrain the aluminum profile in real time to prevent it from bending and deformation due to stress changes, but also does not hinder continuous extrusion, greatly improving the stability and straightness of the aluminum profile during the entire extrusion process, and ensuring the high consistency of product quality.

[0016] 2. When the tail of the aluminum profile leaves the extruder, it enters the reset and circulation preparation stage. The guide linkage block returns to the semicircular groove through the inclined groove, the stop rod retracts with the assistance of the spring, and the transmission chain plate continues to drive in the same direction and moves to the initial position. The entire stop assembly quickly resets. This reset mechanism effectively shortens the extrusion cycle, improves production efficiency, and realizes efficient and continuous operation of the aluminum profile extrusion process.

It should be explained here that the extruder 2 is hydraulically driven, and a long-distance receiving support plate 3 is fixedly installed on the top of the equipment base plate 1, and one end of the long-distance receiving support plate 3 extends to the discharge port of the extruder 2. The long-distance receiving support plate 3 receives the high-temperature aluminum profiles at the discharge port of the extruder 2;

[0029] By natural sliding, the transmission load is reduced. A follow-up positioning assembly and two support seats are provided on the top of the equipment base plate 1 and on both sides of the long-distance material receiving support plate 3. A partition 4 is installed on the top of the equipment base plate 1 and on both sides of the long-distance material receiving support plate 3. The top of the equipment base plate 1 is fixedly connected to the frame, and one side of the frame is fixedly connected to the load-bearing plate. A lifting push rod 6 is fixedly installed on the top of the load-bearing plate, and a cover shell fixed to the bottom end of the lifting push rod 6 is provided below the load-bearing plate. The bottom of the cover shell is movably connected to multiple groups of clamping rollers 5 through bearings.

[0030] Embodiment 2: The follow-up positioning assembly includes multiple groups of positioning cylinders 901 and a corresponding number of positioning rods 902. The positioning cylinder 901 is provided with a spring inside the positioning cylinder 901 for connecting the end of the positioning rod 902 and the inner wall of the positioning cylinder 901. The end of the positioning rod 902 located outside the positioning cylinder 901 is fixedly connected to a positioning auxiliary plate 903. The positioning rod 902 slides in the positioning cylinder 901 and applies lateral pressure through the positioning auxiliary plate 903 to dynamically suppress the bending of the aluminum material.

[0031] A limiting groove is provided on the outer side of the positioning cylinder 901, and a guide linkage block 904 is fixedly connected to the outer side of the positioning rod 902, and the guide linkage block 904 is slidably connected in the limiting groove. The end of the positioning cylinder 901 away from the positioning auxiliary plate 903 is fixedly connected to a cylindrical slider 10.

[0032] The top of the support seat is fixedly connected to a positioning track frame 8, which is composed of two long straight frames and two semicircular frames. The inner walls of the two semicircular frames are provided with semicircular grooves with the same outer contour shape. The inner wall of one long straight frame is provided with a long straight groove 1 connected to the two semicircular grooves end to end, and the inner wall of the other long straight frame is provided with a positioning groove 801 connected to the two semicircular grooves end to end. The positioning groove 801 is composed of two symmetrically arranged oblique grooves and a long straight groove 2, and the two ends of the long straight groove 2 are connected to the two oblique grooves, and the two oblique grooves are respectively connected to the two semicircular grooves, and one end of the guide linkage block 904 is slidably connected to the groove opened on the inner wall of the positioning track frame 8.

[0033] A transmission chain plate 7 that rotates coaxially is installed on the top of the equipment base plate 1 and on both sides of the long-distance material receiving support plate 3. The outer side of the transmission chain plate 7 is fixedly connected to the outer wall of the positioning cylinder 901 through pads arranged at equal intervals. One end of the positioning track frame 8 is fixedly connected to the closed frame 11. The inner wall of the closed frame 11 is provided with a sliding groove that is consistent with the outer contour of the closed frame 11. The cylindrical slider 10 is slidably connected in the sliding groove. The cylindrical slider 10 slides in the sliding groove of the closed frame 11 to constrain the moving trajectory of the positioning cylinder 901 and eliminate the transmission offset of the transmission chain plate 7.

[0034] Combining the first and second embodiments, it can be seen that the working principle of the present invention is as follows:

[0035] Extrusion start-up and initial limit stage: After the extruder 2 is started, the aluminum rod enters the mold cavity after being heated, and the hydraulic cylinder pushes forward, and the aluminum profile is continuously extruded from the discharge port. When the head of the aluminum profile is exposed from the discharge port, the lifting push rod 6 drives the pressing roller 5 to press down to suppress the "head warping" phenomenon of the aluminum profile material due to thermal expansion. The transmission chain plate 7 is driven synchronously, and the linear speed of the transmission chain plate 7 is strictly synchronized with the extrusion speed of the aluminum profile. The guide linkage block 904 moves along the long straight groove 1 and the semicircular groove, and the positioning auxiliary plate 903 is fully retracted to avoid interfering with the initial extrusion of the aluminum profile.

[0036] Extension section: After the guide linkage block 904 enters the inclined slot, the positioning rod 902 extends at a constant speed, and the positioning auxiliary plate 903 fits the side of the aluminum profile, applying lateral pressure to offset the bending tendency caused by the residual stress inside the aluminum profile material;

[0037] Dynamic tightening and continuous guiding stage: When the guide linkage block 904 enters the second long straight slot, the positioning auxiliary plate 903 maintains a constant pressure and moves synchronously with the aluminum profile, forming a "moving fixture" effect;

[0038] Reset and cycle preparation stage; the positioning assembly is reset, and after the tail of the aluminum profile leaves the extruder 2, the guide linkage block 904 returns to the semicircular groove through the inclined groove on the other side, the positioning rod 902 retracts with the assistance of the spring, and the transmission chain plate 7 continues to transmit until it returns to the initial position, waiting for the next extrusion cycle.
