Description

Technical Field

[0001] The invention relates to the field of aluminum product stamping, and in particular to an extrusion production line and process for decorative aluminum profiles. Background Art

[0002] Decorative aluminum profile is an aluminum alloy material specially used for construction and interior decoration. It is lightweight, beautiful, durable, and corrosion-resistant, and is widely used in various decorative scenes. Decorative aluminum profiles are made through an extrusion molding process and can be processed into different shapes and sizes according to design requirements. In the process of extruding aluminum rods into aluminum profiles, the aluminum rods must first be placed in a heating device for heating, in order to make the aluminum rods easier to shape. The heated aluminum rods will be moved to the extrusion device and formed into aluminum profiles through extrusion. However, during the movement, if the moving distance is long and the aluminum rods are exposed to the external environment, the surface temperature of the aluminum rods will drop, and even if they are moved to the extrusion device, their internal temperature may not reach the set temperature required for extrusion. Therefore, before extruding the aluminum rods, it is necessary to ensure that their internal temperature is within a reasonable range.

[0003] However, the existing technology has obvious defects. On the one hand, it is difficult for the current heating device to heat multiple aluminum bars at the same time. On the other hand, even if some devices have the ability to heat multiple aluminum bars at the same time, due to the order of aluminum bar transportation, the heating time and temperature of subsequent aluminum bars need to be precisely controlled. Otherwise, long-term heating will easily cause the aluminum bars to melt, making it impossible to perform subsequent extrusion molding operations.

[0004] In addition, the existing operating method is usually to move all the heated aluminum bars out of the heating device at one time and then extrude them using extrusion equipment. This results in the number of aluminum bars heated at one time being limited by the number of extrusion equipment. If the number of extrusion equipment is insufficient, even if multiple aluminum bars can be heated at the same time, the excess aluminum bars can only wait, which seriously affects production efficiency.

[0005] Therefore, based on the above-stated viewpoints, there is still room for optimization in the existing technology for processing aluminum profiles. Summary of the invention

DETAILED DESCRIPTION

[0043] The following combination Figures 1 to 16 Embodiments of the present invention are described in detail.

[0044] The embodiment of the present application discloses an extrusion production line and process for decorative aluminum profiles, and it is explained that the present application is mainly used in the process of extruding aluminum rod raw materials into aluminum profiles. In terms of technical effect, a plurality of aluminum rods can be preheated by providing a preheating cavity, so that the aluminum rods themselves reach a certain temperature, and can be heated faster when entering a heating device for heating. After the heating is completed, the aluminum rods can be quickly placed in a pre-extrusion mechanism by the heating device to extrude and reduce the diameter of the aluminum rods, so that the aluminum rods can enter the feed port on the extrusion device, and then the aluminum rods are extruded into aluminum profiles by the extrusion device.

[0045] Example 1: Reference Figure 1 and Figure 2 As shown, it includes two symmetrically distributed rectangular boxes 1, a bottom plate 10, a support column 11, a transport unit 2, a partition plate 12, a first chamber 13, a second chamber 14, a third chamber 15, a fourth chamber 16, a heating unit 3, an extrusion unit 5 and an extrusion device 17. Support columns 11 connected to the bottom plate 10 are arranged at the bottom of the two rectangular boxes 1, and the support columns 11 are used to support the corresponding rectangular boxes 1; a transport unit 2 for transporting aluminum bars is arranged between the rectangular boxes 1, and several partition plates 12 distributed at equal intervals are arranged in the rectangular box 1, and the several partition plates 12 divide the interior of the rectangular box 1 from top to bottom into a first chamber 13, a second chamber 14, a third chamber 15 and a fourth chamber 16, and the transport unit 2 can transport the aluminum bars to the first chamber 13 and the second chamber 14.

[0046] Heating plates (not shown) are provided on the inner walls of the first chamber 13 and the second chamber 14. That is, when the transport unit 2 transports the aluminum rod to the first chamber 13, the heating plates are started to preheat the aluminum rod in the first chamber 13 so that the inside of the aluminum rod reaches a certain temperature. However, at this time, the temperature cannot reach the set temperature for extrusion molding of the aluminum rod.

[0047] The second chamber 14 is provided with a heating unit 3 for heating the aluminum rods at high temperature and receiving the aluminum rods transported by the transport unit 2. The transport unit 2 then transports the pre-heated aluminum rods to the heating unit 3. Since the aluminum rods have been pre-heated, the heating unit 3 can quickly heat the aluminum rods at a higher heating temperature, thereby increasing the efficiency of the aluminum rods.

[0048] The third chamber 15 is provided with an extrusion unit 5 for reducing the diameter of the aluminum rod. After the aluminum rod is heated, it is transferred to the extrusion unit 5 by the heating unit 3, and then the extrusion unit 5 pre-extrudes the aluminum rod to reduce its diameter.

[0049] An extrusion device 17 for forming and extruding the aluminum rod is arranged in the fourth chamber 16 , so that the aluminum rod with a reduced diameter can enter the extrusion device 17 and then be extruded into an aluminum profile by the extrusion device 17 .

[0050] Reference Figure 3 and Figure 4 As shown, a transport unit 2 for transporting aluminum bars is provided; specifically, the transport unit 2 includes a conveyor 20, a conveyor belt 21, an arc frame plate 22, an arc plate 23 and a thickened plate 24. Two conveyors 20 are arranged between the rectangular box 1, and the conveyors 20 are symmetrically distributed on both sides of the rectangular box 1. The conveyor belt 21 is provided on the conveyor 20, and the conveyor 20 drives the conveyor belt 21 to move. The outer side of the conveyor belt 21 is provided with a plurality of arc frame plates 22 distributed along its extension section, and the arc plate 23 is slidably provided inside the arc frame plate 22. That is, the conveying device 20 drives the conveyor belt 21 to move on its end surface, and the conveyor belt 21 can drive the arc frame plate 22 to move synchronously with it during the movement. The arc plate 23 can move in the left and right directions under the limit guide of the corresponding arc frame plate 22. When the arc frame plates 22 on the two conveying devices 20 move into a chamber 13 together, the arc plates 23 in the two arc frame plates 22 will correspond to each other. At this time, the aluminum rod is placed on the two arc plates 23, and the arc plates 23 support the aluminum rod.

[0051] At the same time, the heating plate in the first chamber 13 can preheat the aluminum rod, and similarly, the heating plate in the second chamber 14 will also heat the second chamber 14; a thickened plate 24 is provided on the inner diameter of the side of the arc plate 23 away from the arc frame plate 22, and the inner diameter of the thickened plate 24 corresponds to the arc frame plate 22, and an electric push rod (not shown) is provided between the inner wall of the arc frame plate 22 and the arc plate 23, and the thickened plate 24 contacts the outer side of the aluminum rod. When the aluminum rod is too long, the outer side of the aluminum rod can contact the inner diameter of the arc frame plate 22. At this time, the thickened plate 24 contacts the outer side of the aluminum rod so that the arc plate 23 can also support the aluminum rod, and the electric push rod can push the arc plate 23 to move inside the arc frame plate 22 to adapt to aluminum rods of different lengths.

[0052] Continue to refer to Figure 3 , Figure 5 and Figure 6 As shown, a heating unit 3 is used for heating the aluminum rod at high temperature and receiving the aluminum rod on the transport unit 2; specifically, the heating unit 3 includes a rotating shaft 30, a supporting plate 31, a supporting screw 32, a sliding plate 33, a pushing arc plate 34 and a through groove 35, the rotating shaft 30 is rotatably arranged on the inner wall of the second chamber 14, and a supporting plate 31 with an arc-shaped cross-section is commonly arranged between the rotating shafts 30, and a high-temperature hot plate (not shown) is arranged inside the supporting plate 31, that is, the rotating shaft 30 can drive the corresponding supporting plate 31 to rotate, and the supporting plate 31 can support the aluminum rod, and the high-temperature heating plate inside it is in contact with the outer side of the aluminum rod, and the aluminum rod is heated at high temperature, so that the aluminum rod can quickly reach a predetermined extrusion temperature.

[0053] Two symmetrically distributed supporting cavities are provided in the supporting plate 31, one side of the supporting cavity penetrates to the inner wall of the supporting plate 31, a supporting screw rod 32 is rotatably provided on the inner wall of the supporting cavity, and a sliding plate 33 is also slidably provided inside the supporting cavity, and the sliding plate 33 is threadedly connected to the supporting screw rod 32, and one side of the sliding plate 33 extends out of the supporting cavity and is jointly provided with a pushing arc plate 34 on the outside. When the arc plate 23 drives the aluminum rod to be located at the upper end of the supporting plate 31, the outer side of the aluminum rod will contact the pushing arc plate 34. At this time, the two arc plates 23 are retracted into the arc frame plate 22 under the drive of the corresponding electric push rod, and the aluminum rod is no longer supported and falls onto the inner diameter of the supporting plate 31.

[0054] When the supporting screw rod 32 is driven to rotate by external force, it can drive the corresponding sliding plate 33 to move back and forth in the supporting cavity, and the sliding plate 33 can drive the pushing arc plate 34 to push the aluminum rod to move on the supporting plate 31. That is, after the aluminum rod is heated, the rotating shaft 30 drives the arc plate 23 to rotate one hundred and eighty degrees, so that the aluminum rod is perpendicular to the extrusion unit 5 at the lower end, and then the pushing arc plate 34 pushes the aluminum rod to move into the extrusion unit 5 at the lower end under the indirect drive of the supporting screw rod 32.

[0055] The upper side of the push arc plate 34 is an inclined surface, which is skewed toward the support plate 31. That is, when the aluminum rod falls on the support plate 31, the inclined surface on the push arc plate 34 can guide one side of the aluminum rod along its end face to enter the support plate 31, preventing the aluminum rod from falling at a skewed angle.

[0056] The two uppermost partition plates 12 are both provided with through grooves 35, and the through grooves 35 allow the first chamber 13 and the second chamber 14 to be interconnected, that is, the heat emitted by the heating plate and the high-temperature hot plate in the first chamber 13 and the second chamber 14 can flow through the through grooves 35, thereby more effectively utilizing the heat without causing waste.

[0057] The rotating shaft 30 on one side passes through the outer wall of the corresponding rectangular box 1 and is connected to the output shaft of the external driving motor, and is driven to rotate by the external driving motor.

[0058] Continue to refer to Figure 6 and Figure 7 As shown, a blocking component 4 is also provided between the rotating shafts 30 to prevent the aluminum rod on the supporting plate 31 from accidentally falling off when the supporting plate 31 rotates; specifically, the blocking component 4 includes a sliding groove 40, a blocking plate 41, a driven groove 42 and a return spring 43, the sliding groove 40 is opened inside the rotating shaft 30 and passes through the outer wall of the rotating shaft 30, and a blocking plate 41 is slidably provided in the sliding groove 40, that is, the blocking plate 41 can reciprocate in the corresponding sliding groove 40.

[0059] A sliding groove 40 is extended from one side of the two blocking plates 41 and a driven groove 42 is opened, and the driven grooves 42 on the two rotating shafts 30 are symmetrically distributed. A return push spring 43 is also arranged between the blocking plate 41 and the sliding groove 40. The return push spring 43 drives one side of the corresponding blocking plate 41 to be located outside the sliding groove 40 in the initial state. At this time, the end distances of the two blocking plates 41 are close. When the aluminum rod falls from the arc plate 23, the outer side of the aluminum rod contacts the end face of the driven groove 42, and drives the corresponding blocking plate 41 to be retracted into the corresponding sliding groove 40 through the driven groove 42. At this time, there is no blocking plate 41 to prevent the aluminum rod from falling into the arc plate 23. Then the return push spring 43 drives the corresponding blocking plate 41 to move to the initial position to block the aluminum rod. At this time, the supporting plate 31 rotates under the drive of the rotating shaft 30, and the outer side of the aluminum rod is limited by one side of the blocking plate 41 and will not separate from the supporting plate 31.

[0060] Reference Figure 8 , Fig.12 and Fig.13As shown, the extrusion unit 5 is used to reduce the diameter of the aluminum rod; specifically, the extrusion unit 5 includes a conical cylinder 50, an extrusion groove 51, an extrusion screw 52, ​​a driving block 53, an extrusion plate 54 and a limit plate 55. The conical cylinder 50 is arranged between the blocking plates 41 corresponding to the three chambers 15. Both ends of the conical cylinder 50 are through-shaped, and the upper end opening of the conical cylinder 50 corresponds to one side of the support plate 31, and the lower end opening of the conical cylinder 50 corresponds to the feed port at the upper end of the extrusion device 17, that is, the inner diameter of the conical cylinder 50 gradually decreases from top to bottom.

[0061] It can be seen from this that after the rotating shaft 30 drives the supporting plate 31 to flip, one end of the aluminum rod will correspond to the upper opening of the conical cylinder 50. At this time, the outer side of the aluminum rod is in contact with the inner diameter of the conical cylinder 50, and then the pushing arc plate 34 pushes the aluminum rod into the conical cylinder 50 under the drive of the corresponding supporting screw rod 32. The diameter of the aluminum rod will gradually shrink under the extrusion of the inner wall of the conical cylinder 50, and then the extruded aluminum rod will move out from the opening at the lower end of the conical cylinder 50. However, at this time, the pushing arc plate 34 can only push the aluminum rod completely into the conical cylinder 50, but cannot completely push the aluminum rod out of the conical cylinder 50.

[0062] An extrusion groove 51 which penetrates the interior of the conical cylinder 50 is opened on one side, an extrusion screw rod 52 is rotatably arranged on the inner wall of the extrusion groove 51, and a driving block 53 which is threadably connected to the extrusion screw rod 52 is slidably arranged in the extrusion groove 51. The extrusion screw rod 52 can drive the driving block 53 to move up and down in the conical cylinder 50 under the limit guide of the corresponding extrusion groove 51.

[0063] One side of the driving block 53 is hinged with an extrusion plate 54 located inside the conical cylinder 50 through a torsion spring, and one side of the driving block 53 is provided with a limiting plate 55 in contact with the extrusion plate 54, that is, the extrusion plate 54 can swing along its hinge point, and under the limitation of the limiting plate 55, the extrusion plate 54 can only swing downward, and in the initial state, the extrusion plate 54 is limited by the torsion spring at its hinge point and remains level with the conical cylinder 50.

[0064] That is, when the aluminum rod enters the conical cylinder 50, the end of the aluminum rod contacts the upper end of the extrusion plate 54 and drives the extrusion plate 54 to swing downward to avoid the travel path of the aluminum rod. When the aluminum rod completely enters the conical cylinder 50, the extrusion screw 52 indirectly drives the extrusion plate 54 to move to the upper end of the aluminum rod, and then the extrusion plate 54 is driven by the torsion spring to swing back to the initial position. Thereafter, the extrusion screw 52 rotates in the opposite direction to drive the extrusion plate 54 to move toward the direction of the aluminum rod, thereby driving the aluminum rod to move downward and drive the aluminum rod to move out from the opening at the lower end of the conical cylinder 50. When the aluminum rod moves out from the opening at the lower end of the conical cylinder 50, its diameter has been extruded to a predetermined size.

[0065] Continue to refer to Figure 8 , Fig. 9, Fig.10 and Fig.11 As shown, specifically, it includes a synchronization groove 6 and a synchronization key 60. One side of the extrusion screw rod 52 passes through the outer wall of the tapered cylinder 50 to open a synchronization groove 6, and one end of the supporting screw rod 32 on one side also passes through the outer wall of the supporting plate 31 to be provided with a synchronization key 60 corresponding to the synchronization groove 6, and the other side of the two supporting screw rods 32 also passes through the outer wall of the corresponding supporting plate 31 and is connected by belt drive.

[0066] That is, the supporting screw 32 can be rotated synchronously by belt transmission, and the end of the supporting screw 32 on one side can be connected to the output shaft of the external driving motor, and driven to rotate by the external driving motor. When the supporting plate 31 swings to correspond to the upper end of the tapered cylinder 50, the synchronization key 60 on the upper end of the supporting screw 32 on one side will be inserted into the synchronization groove 6 on the corresponding extrusion screw 52, ​​and the threaded grooves on the supporting screw 32 and the extrusion screw 52 are opposite. In the initial state, the driving block 53 is located at the lower end of the tapered cylinder 50. When the supporting screw 32 rotates, the extrusion screw 52 is driven to rotate by the synchronization key 60 and the synchronization groove 6.

[0067] The pushing arc plate 34 pushes the aluminum rod downward and pushes the aluminum rod into the conical cylinder 50. At the same time, the extrusion plate 54 moves upward under the drive of the driving block 53, and finally moves to correspond to the top wall of the extrusion groove 51. Then the supporting screw rod 32 rotates in the opposite direction to drive the pushing arc plate 34 to move back to the initial position. At the same time, the extrusion screw rod 52 also rotates in the opposite direction, indirectly driving the extrusion plate 54 to push the aluminum rod, and finally pushing the aluminum rod out of the opening at the lower end of the conical cylinder 50. After moving out of the conical cylinder 50, the aluminum rod directly enters the interior of the extrusion device 17, and the extrusion device 17 extrude it immediately. Finally, the aluminum rod is extruded into an aluminum profile and moves out from the discharge port at the lower end of the extrusion device 17.

[0068] Example 2: Reference Fig.14 , Fig.15 and Fig.16 As shown, on the basis of the first embodiment, after the aluminum profile is extruded from the discharge port of the extrusion device 17, in order to be able to cut the aluminum profile to a specified length, a cutting unit 7 is arranged between the support columns 11; specifically, the cutting unit 7 includes a rectangular block 70, a cutting groove 71, a cutting plate 72, a cutting knife 73, a reciprocating screw rod 74 and a gearbox 75, the rectangular block 70 is jointly arranged between two corresponding support columns 11 on the left and right, that is, there are two symmetrically distributed rectangular blocks 70, a cutting groove 71 is opened inside the rectangular block 70, and one side of the cutting groove 71 passes through its outer wall, and the openings of the two cutting grooves 71 correspond to each other, a cutting plate 72 is slidably arranged inside the cutting groove 71, and a cutting knife 73 located outside the cutting groove 71 is arranged on one side of the cutting plate 72, and the cutting knife 73 is arc-shaped, and the two cutting knives 73 correspond to each other.

[0069] The support column 11 can support the corresponding rectangular block 70, and the cutting plate 72 can drive the cutting knife 73 to move back and forth in the cutting groove 71 when driven by external force. The two cutting knives 73 move in relative directions to cut the aluminum profile. That is, after the cutting knife 73 completes cutting the aluminum profile, since the middle part is a circular arc through shape and the end face of the cutting knife 73 is an arc shape, even if the residue on the aluminum profile falls on the cutting knife 73 during the cutting process, it will slide from the outside of the cutting knife 73 to prevent the residue from being brought into the cutting groove 71 by the cutting knife 73 and interfering with the moving path of the cutting knife 73.

[0070] One side of the rectangular block 70 is rotatably provided with a reciprocating screw rod 74 which penetrates the corresponding cutting groove 71. One side of the reciprocating screw rod 74 is threadedly connected to the corresponding cutting plate 72. A gearbox 75 is installed on one side of the rectangular block 70. The other side of the reciprocating screw rod 74 penetrates the outer wall of the rectangular block 70 and is connected to the main shaft of the gearbox 75. The main shaft of the gearbox 75 is connected to the driving shaft on the conveying device 20 by belt transmission. That is, when the conveying device 20 drives the conveyor belt 21 to move, its driving shaft will also move. The drive shaft will rotate, so the drive shaft will drive the main shaft in the gearbox 75 to rotate through the belt drive, and the main shaft of the gearbox 75 will drive the corresponding reciprocating screw 74 to rotate, and the reciprocating screw 74 will drive the cutting knife 73 to reciprocate through the cutting plate 72, and the rotation speed of the main shaft of the gearbox 75 can be controlled to adjust the movement speed of the cutting knife 73, while the falling speed of the aluminum profile is unchanged, so the cutting length of the aluminum profile by the cutting knife 73 can be adjusted by controlling the rotation speed of the reciprocating screw 74.
