Description

Technical Field

[0001] The present invention relates to the technical field of extrusion molding, and particularly relates to an extrusion molding device for aluminum alloy door and window profiles. Background Art

[0002] The extrusion molding technology for aluminum alloy door and window profiles is an advanced metal processing technology, which is widely used in the construction industry, especially in the manufacture of high-grade doors and windows. This technology uses high pressure to extrude aluminum alloy billets through an extruder into aluminum profiles with the required cross-sectional shapes. The specific processing process is to first cut the raw materials into aluminum rods of the required length by a cutting mechanism, then push the aluminum rods onto a feeding mechanism, the feeding mechanism drives the aluminum rods to move to the position of the extrusion device, then the extruder drives the extrusion column to move down coaxially with the aluminum rods, and then the extruder moves to push the aluminum rods towards the forming mechanism through the extrusion column. The molds with corresponding shapes in the forming mechanism then perform forming processing on the pushed-in aluminum rods.

[0003] However, the following problems exist in the transportation and moving extrusion process of aluminum rods at present: when the cut aluminum rods move to the position of the extruder, only the rolling range is restricted by a limiting plate without an additional fixing mechanism, so that the aluminum rods are prone to rolling during the movement, resulting in bump damage on the surface of the aluminum rods, thus affecting the quality of profile processing. Secondly, during the process of pushing the aluminum rods into the forming mechanism, there is no additional device for guiding the aluminum rods, resulting in the aluminum rods being not easily pushed into the forming mechanism, affecting the smoothness of aluminum profile processing, and easily causing damage to the aluminum rods and equipment.

[0019] Third, during the process of the positioning part provided in the present invention moving from the extrusion mechanism to the forming mechanism, first, the compression spring is used to push the fixing plate to move, and the fixing plate then pushes the corresponding shaft seat to move. The shaft seat drives the corresponding first connecting plate to move upward through the connecting rod to limit the movement of the support plate and further limit the movement of the corresponding skateboard, ensuring the pressing and guiding of the guiding column against the corresponding aluminum rod, thereby further ensuring the fluency of the aluminum rod moving into the forming mechanism.

Detailed Description of the Invention

[0030] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the following will describe the specific embodiments of the present invention in detail with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0031] Such as Figure 1As shown in the figure, an extrusion forming device for aluminum alloy door and window profiles includes a receiving plate 10; support legs are uniformly and fixedly installed at the lower end of the receiving plate 10, and a forming mechanism 2 is arranged at the rear side of the receiving plate 10. Since the forming mechanism 2 is a prior art, no more details will be described here. A bottom plate 11 that penetrates from below the receiving plate 10 is arranged at the front side of the forming mechanism 2. An extrusion mechanism 4 is arranged at the upper end of the bottom plate 11, and a feeding mechanism 3 is arranged on the receiving plate 10.

[0032] As Figure 1 and Figure 2 As shown in the figure, the feeding mechanism 3 includes a vertical plate 30. Two vertical plates 30 are symmetrically and slidably installed on the upper end of the receiving plate 10 from left to right. A support plate 31 is fixedly installed between the two vertical plates 30. Fixing parts 32 for fixing the aluminum rod and guiding it when the aluminum rod moves into the forming mechanism 2 are uniformly arranged on the support plate 31 from left to right. A positioning part 33 is arranged on the receiving plate 10, and a driving part 34 for driving the two vertical plates 30 to move is also arranged on the receiving plate 10.

[0033] As Figure 1 and Figure 2 As shown in the figure, the extrusion mechanism 4 includes a seat body 40. The seat body 40 is slidably installed on the upper end of the bottom plate 11 from front to back. A fixed seat 41 is slidably installed on the upper and lower ends of the rear end of the seat body 40. An extrusion column 42 is fixedly installed at the rear end of the fixed seat 41. An unlocking part 43 for releasing the clamping of the aluminum rod by the fixing part 32 and for driving the positioning part 33 to limit the moved support plate 31 is arranged on the fixed seat 41. A pushing and pulling part 44 for driving the seat body 40 and the fixed seat 41 to move is arranged on the bottom plate 11.

[0034] During specific operation, an external conveying mechanism pushes the cut aluminum rod to the corresponding fixing part 32 until the aluminum rod is pushed in place. Then, the fixing part 32 fixes the corresponding aluminum rod. Then, the driving part 34 pushes the fixed aluminum rod to move between the forming mechanism 2 and the extrusion mechanism 4 in sequence. And whenever the aluminum rod moves to this position, the pushing and pulling part 44 will push the extrusion column 42 to move downward to be coaxial with the corresponding aluminum rod. Then, the pushing and pulling part 44 pushes the seat body 40 towards the forming mechanism 2. The seat body 40 drives the unlocking part 43 through the fixed seat 41 to release the fixed state of the corresponding aluminum rod by the fixing part 32, retaining its guiding function. Then, the extrusion column 42 abuts against the corresponding aluminum rod and pushes the aluminum rod into the forming mechanism 2 for forming processing through the forming mechanism 2.

[0035] As Figure 2 and Figure 3As shown, the fixing part 32 includes a limiting component. A limiting component is slidably installed on the upper end of the support plate 31 from left to right. The limiting component consists of two symmetrically arranged sliding plates 320 from left to right. A support plate 321 is fixedly installed at the upper end of the sliding plate 320. Connecting plates 323 are installed on the opposite faces of the two support plates 321 in the same group through first compression springs 322. Clamping blocks 324 are fixedly installed on the opposite faces of the two connecting plates 323 in the same group from front to back at equal intervals. An actuator 5 for driving the two sliding plates 320 in the same group to move towards the corresponding aluminum bar is arranged at the lower end of the support plate 31. A locking component 6 is arranged between the connecting plate 323 and the corresponding support plate 321. A guiding component is arranged on the sliding plate 320.

[0036] As Figure 2 and Figure 4 shown, the actuator 5 includes a chute 50. Chutes 50 are opened on the support plate 31 corresponding to the sliding plates 320 one by one. Sliders fixedly connected to the corresponding sliding plates 320 are slidably installed in the chutes 50. A spur gear 51 is rotatably installed in the middle of the lower end of the support plate 31. Rack bars 52 slidably connected to the support plate 31 are meshed on both the front and rear sides of the spur gear 51. The sliding plate 320 located on the left side in each group of limiting components is fixedly connected to the front rack bar 52 through the corresponding slider. The sliding plate 320 located on the right side in each group of limiting components is fixedly connected to the rear rack bar 52 through the corresponding slider. A third hydraulic cylinder 53 is fixedly installed at the left end of the left vertical plate 30. The telescopic section of the third hydraulic cylinder 53 slidably penetrates through the corresponding vertical plate 30 and is fixedly connected to the front rack bar 52.

[0037] As Figure 3 shown, the guiding component includes guiding columns 325. Guiding columns 325 are arranged on both the front and rear sides of each clamping block 324 and are rotatably connected to the corresponding sliding plates 320. A support seat 326 fixedly installed on the support plate 31 is arranged between the two sliding plates 320 in the same group. A V-shaped groove is opened at the upper end of the support seat 326. Roller shafts are rotatably installed on the inner wall of the V-shaped groove from front to back at equal intervals.

[0038] During specific operation, an external conveying mechanism pushes the cut aluminum bars onto the corresponding support seats 326 until the aluminum bars are pushed in place. Then, an external hydraulic pump is connected to the third hydraulic cylinder 53 through an external third conveying pipe. An electromagnetic valve is installed on the external third conveying pipe. The third hydraulic cylinder 53 is controlled by the electromagnetic valve to push the corresponding rack bar 52 to move. The rack bar 52 drives the corresponding sliding plate 320 to move towards the corresponding aluminum bar through the corresponding slider. The rack bar 52 pushed by the third hydraulic cylinder 53 drives the other rack bar 52 to move away from each other through the spur gear 51. Thus, the two sliding plates 320 in the same group move towards the corresponding aluminum bar synchronously through the movement of the two rack bars 52, enabling the clamping blocks 324 and the guiding columns 325 to press against the aluminum bar to fix the aluminum bar, avoiding shaking and collision during the subsequent movement of the aluminum bar and affecting the processing quality.

[0039] As Figure 1 and Figure 2 shown, the driving part 34 includes a bearing plate 340. Bearing plates 340 are fixedly installed at both the left and right ends of the receiving plate 10. A lead screw 341 is rotatably installed between the two bearing plates 340. Both vertical plates 30 are threadedly connected to the lead screw 341. A motor 342 is fixedly installed at the left end of the left bearing plate 340, and the output shaft of the motor 342 is fixedly connected to the lead screw 341.

[0040] As Figure 1 and Figure 2 shown, the pushing and pulling part 44 includes a first hydraulic cylinder 440. The first hydraulic cylinder 440 is fixedly installed at the rear end of the seat body 40. The telescopic section of the first hydraulic cylinder 440 is fixedly connected to the upper end of the fixed seat 41. A second hydraulic cylinder 441 is fixedly installed at the upper end of the bottom plate 11 and is located on the front side of the seat body 40. The telescopic section of the second hydraulic cylinder 441 is fixedly connected to the front end of the seat body 40.

[0041] During specific operation, after the aluminum rod is fixed by the fixing part 32, the motor 342 drives the lead screw 341 to rotate. The lead screw 341 then drives the fixing part 32 and the fixed aluminum rod to move rightward in sequence through the vertical plates 30 to the position corresponding to the extrusion mechanism 4. Then, an external hydraulic pump is connected to the first hydraulic cylinder 440 through an external first delivery pipe. An electromagnetic valve is installed on the external first delivery pipe. The electromagnetic valve controls the first hydraulic cylinder 440 to push the fixed seat 41 downward. The fixed seat 41 drives the extrusion column 42 to move to be coaxial with the corresponding aluminum rod, and the unlocking part 43 moves downward to the position to be unlocked synchronously. After that, the external hydraulic pump is connected to the second hydraulic cylinder 441 through an external second delivery pipe. An electromagnetic valve is also installed on the external second delivery pipe. The electromagnetic valve controls the second hydraulic cylinder 441 to push the seat body 40 toward the forming mechanism 2. First, the unlocking part 43 fixes the support plate 31 and releases the fixing of the corresponding aluminum rod by the fixing part 32. Then, the extrusion column 42 pushes the corresponding aluminum rod into the forming mechanism 2 for forming processing.

[0042] As Figure 3 , Figure 5 , Figure 6 and Figure 7 shown, the locking part 6 includes a rectangular plate 60. Rectangular plates 60 are fixedly installed at the opposite ends of the two connecting plates 323 in the same group. A limiting column 61 slidably penetrates through the rectangular plate 60. A limiting hole 62 that cooperates with the corresponding limiting column 61 is formed in the support plate 321. A column 63 is arranged on the side of the limiting column 61 close to the support seat 326 in the same group and slidably penetrates through the corresponding rectangular plate 60. A ball is rotatably installed at the lower end of the column 63. A first connecting plate 64 is fixedly installed at the upper ends of the column 63 and the corresponding limiting column 61. A tension spring 65 is installed between the lower end of the first connecting plate 64 and the corresponding rectangular plate 60.

[0043] As Figure 2 , Figure 5 and Figure 6 shown, the unlocking part 43 includes a fixing plate 430. A fixing plate 430 is sleeved on the extrusion column 42 in a sliding manner. Compression springs 431 are evenly installed between the front end of the fixing plate 430 and the fixed seat 41. A support plate 432 is installed on the lower end of the receiving plate 10 to slide back and forth. A guide post 433 that slidably penetrates the support plate 432 is fixedly installed at the lower end of the fixing plate 430. Two lifting plates 434 that are symmetric about the extrusion column 42 are fixedly installed on the upper part of the rear end of the fixing plate 430. The lower front side of the column 63 is an inclined surface. A slope that cooperates with the inclined surface on the column 63 is provided at the upper end of the rear side of the lifting plate 434. Push plates 435 are fixedly installed at the opposite ends of the two lifting plates 434. The push plate 435 has a right trapezoidal structure with an inclined surface facing away from the extrusion column 42. A baffle plate 436 that cooperates with the push plate 435 is fixedly installed at the lower end of the rectangular plate 60. A lifting member 7 for driving the positioning part 33 is provided at the rear end of the fixing plate 430.

[0044] As Figure 2 , Figure 3 and Figure 5 shown, the positioning part 33 includes a through hole 330. Two through holes 330 are symmetrically opened on the front and rear of the sliding plate 320. Round holes corresponding to the through holes 330 are opened on the support plate 31. Through holes corresponding to the through holes 330 on the two sliding plates 320 in the corresponding limiting components are opened on the receiving plate 10 between the extrusion mechanism 4 and the forming mechanism 2. Plug rods 331 slidably penetrate through the through holes. A second connecting plate 332 is fixedly installed at the lower ends of the two relatively left and right plug rods 331. A second compression spring 333 is installed between the upper end of the second connecting plate 332 and the receiving plate 10.

[0045] As Figure 2 , Figure 5 and Figure 6 shown, the lifting member 7 includes a connecting rod 70. A connecting rod 70 is hinged at both the left and right ends of the second connecting plate 332. A shaft seat is hinged at the end of the connecting rod 70 away from the corresponding second connecting plate 332. The shaft seat is slidably installed on the lower end of the receiving plate 10 left and right. A driving plate 71 is installed at the ends of the two relatively front and rear shaft seats close to the second compression spring 333. A pushing plate 72 that cooperates with the driving plate 71 is fixedly installed at the rear end of the fixing plate 430. Both the driving plate 71 and the pushing plate 72 have a right trapezoidal structure.

[0046] During specific operation, the solenoid valve on the external No. 2 conveying pipe controls the No. 2 hydraulic cylinder 441 to push the seat body 40 to move toward the forming mechanism 2, and the fixed plate 430 will be pushed to move through the fixed seat 41 and the compression spring 431. The fixed plate 430 will first contact the driving plate 71 through the pushing plate 72 to push the driving plate 71 to move away from the No. 2 compression spring 333. The driving plate 71 will drive the corresponding No. 2 connecting plate 332 to move upward through the shaft seat and the connecting rod 70, and the No. 2 connecting plate 332 will drive the insertion rod 331 to penetrate the corresponding circular hole and the through hole 330 to further improve the stability of the support plate 31 and the corresponding slide plate 320.

[0047] As the fixed plate 430 moves, the lifting plate 434 contacts the column 63 to push the corresponding column 63 to move upward, and the column 63 drives the limiting column 61 to move upward through the corresponding No. 1 connecting plate 64, so that the limiting column 61 disengages from the corresponding limiting hole 62 and stretches the tension spring 65 at the same time. Then, the pushing plate 435 contacts the corresponding abutment plate 436 to push the connecting plate 323 away from the corresponding aluminum rod, and the connecting plate 323 drives the clamping block 324 away from the corresponding aluminum rod to release the fixation of the corresponding aluminum rod and compress the No. 1 compression spring 322, while the guide column 325 maintains the contact and guidance with the corresponding aluminum rod.

[0048] Then the fixing plate 430 contacts with the receiving plate 10 to limit the further movement of the fixing plate 430. After that, as the seat body 40 moves, the compression spring 431 will be compressed to continue to move, and the extrusion column 42 will contact with the aluminum rod to push the aluminum rod into the forming mechanism 2 for forming processing. After the processing is completed, the solenoid valve on the external No. 2 conveying pipe controls the No. 2 hydraulic cylinder 441 to pull the seat body 40 away from the forming mechanism 2, and the push plate 435 moves forward away from the stop plate 436. The connecting plate 323 moves toward the corresponding support seat 326 under the action of the No. 1 compression spring 322, and drives the The corresponding clamping block 324 moves to reset, and then the lifting plate 434 moves away from the column 63. At this time, the column 63 is not blocked, so that under the action of the tension spring 65, the limiting column 61 is driven by the No. 1 connecting plate 64 to insert into the corresponding limiting hole 62 to fix the clamping block 324, and then the pushing plate 72 moves away from the driving plate 71, and the insertion rod 331 moves downward and separates from the support plate 31 under the action of the No. 2 compression spring 333, and then the extrusion column 42 moves away from the support plate 31 to reset, and the driving part 34 drives the next fixed aluminum rod to move to the position of the forming mechanism 2, and then repeats the above operation to continue the aluminum profile forming process.

[0049] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by orientation words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom", etc. is usually based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description.
