Description

Technical Field

[0001] This invention relates to the field of aluminum profile processing, and specifically to an aluminum alloy profile extrusion device and process. Background Technology

[0002] Aluminum profiles are increasingly widely used in daily life and production due to their advantages such as light weight, high strength and beautiful appearance. Extrusion forming is the most important production method for aluminum profiles. Its basic principle is to put heated aluminum rods into the die cavity of an extruder, and the aluminum material is filled into the die cavity by the extrusion action of the die, and then processed into the required cross-sectional shape.

[0003] Chinese Patent Publication No. CN117548517A discloses an extrusion press for aluminum profiles, comprising a base, a connecting seat, and an extrusion die. A hydraulic telescopic cylinder is mounted on one end of the top of the base, and a support frame is fixedly connected to the surface of the hydraulic telescopic cylinder. A stabilizing mechanism is provided on the surface of the hydraulic telescopic cylinder. The connecting seat is fixedly connected to the other end of the top of the base, and a first connecting groove is horizontally formed through the center of the surface of the connecting seat. A feeding seat is provided on the side of the connecting seat near the hydraulic telescopic cylinder, and the feeding seat is fixedly connected to the top of the base. The top of the feeding seat is inclined, and a feeding mechanism is provided inside the feeding seat. The extrusion die is located on the other side of the connecting seat, and the extrusion die is located on the surface of the first connecting groove. A connecting mechanism for connecting the extrusion die to the connecting seat is provided on the surface of the extrusion die. This invention, through the arrangement of multiple columns and pallets, allows aluminum raw materials to be placed on the top of the feeding seat at any time, thereby improving the working efficiency of the device and making aluminum profile extrusion faster.

[0004] The above-mentioned aluminum profile extrusion device also has the following problems when in use: the above-mentioned aluminum profile extrusion device requires the ratchet die to be disassembled and installed by means of screw connection, which makes it inconvenient to replace the whole extrusion die, and additional tools are required to store the die, making the replacement operation inconvenient.

[0005] Therefore, it is necessary to invent an aluminum alloy profile extrusion device and process to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide an aluminum alloy profile extrusion device and process to solve the problem mentioned in the background art that the aluminum profile extrusion device requires screw connection to replace and install the ratchet die during use, which makes it inconvenient to replace the entire extrusion die and requires additional tools to store the die, making the replacement operation inconvenient.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an aluminum alloy profile extrusion device and process, comprising a frame, a side plate fixedly connected to the end of the frame, and a hydraulic telescopic cylinder fixedly installed on the end wall of the side plate; a mold mounting plate fixedly installed on the top of the frame, and a movable cavity formed inside the mold mounting plate, with a movable plate movably connected inside the movable cavity; a mounting hole formed inside the movable plate; a through hole formed inside the mold mounting plate, the through hole communicating with the mounting hole and the movable cavity; a conveying roller provided at the front end of the mold mounting plate; and further comprising:

[0008] The mold assembly has a threaded groove on the inner wall of the mounting hole, and the mold body is threadedly connected to the inside of the threaded groove. The outer wall of the mold body is threaded, and a connecting block is fixedly connected to the outer wall of the mold body. The connecting block is fixedly connected to the inner wall of the sleeve, and the sleeve moves within a channel provided inside the movable plate.

[0009] The limiting installation component has a notch at the top of the mold mounting plate, and a fixing rod is fixedly connected to the inner wall of the notch. A lever is movably sleeved on the outer ring of the fixing rod. The lever is movably connected to the bottom wall of the notch via a spring. The end of the lever is movably connected to a fitting block. The fitting block passes through a limiting groove at the top of the mold mounting plate and matches the fitting groove, which is located at the top of the moving plate.

[0010] Preferably, the cross-section of the movable plate is "I" shaped, and the side wall of the movable plate is attached to and slidably connected to the inner wall of the movable cavity to ensure the stability of the movable plate's movement. At the same time, the connecting block protruding from the mold body can also move inside the movable cavity and within the reserved movable space.

[0011] Preferably, the number of mounting holes is five, and the five mounting holes are distributed in a line at equal intervals on the movable plate, so as to install five mold bodies at the same time for switching use.

[0012] Preferably, the depth of the sleeve is less than the depth of the mold body, and a gap is left between the inner wall of the sleeve and the outer wall of the mold body;

[0013] The outer wall of the sleeve fits and slides against the inner wall of the channel. When the end of the sleeve abuts against the deepest part of the channel, it indicates that the mold body is installed and no further twisting is required.

[0014] Preferably, there are two fixing rods, and the two fixing rods are symmetrically distributed with reference to the central axis of the mold mounting plate, so as to ensure that the two sets of limiting installation components restrict the installation of the moving plate.

[0015] Preferably, the interlocking block is composed of three blocks. The middle position of the interlocking block is connected to the upper block and the lower block by a columnar short rod. The columnar short rod is located inside a circular hole at the inclined end of the lever, so that the movement of the interlocking block connected to the end of the lever can be synchronously adjusted when the lever is turned. The inner diameter of the circular hole is slightly larger than the outer diameter of the columnar short rod. There is a space for movement between the columnar short rod and the circular hole, which ensures that the synchronous movement of the lever and the interlocking block is feasible, and also facilitates the linear movement of the interlocking block under the limiting position of the limiting groove.

[0016] Preferably, one end of the spring is fixedly connected to the bottom wall of the horizontal end of the lever, and the other end of the spring is fixedly connected to the inner wall of the notch. The spring's own elastic force presses against the lever, causing the lever to be in a certain position. Figure 5 In the initial state shown, the interlocking block passes through the limiting slot and matches the interlocking slot set on the top of the moving plate.

[0017] Preferably, there are five fitting slots, and the positions of the five fitting slots correspond one-to-one with the positions of the five mounting holes.

[0018] The present invention also provides an aluminum profile extrusion process, which uses the above-mentioned aluminum alloy profile extrusion device, and the specific operation steps are as follows:

[0019] Step 1: Aluminum rod pretreatment. Lay the aluminum rods flat on the material rack with gaps between them and heat them for 3.5 hours until the temperature of the aluminum rods reaches 480 degrees Celsius, and keep them at that temperature for 1 hour.

[0020] Step 2: Mold matching. Pull out the movable plate to match the mold body to be used with the through hole, and then limit the installation of the movable plate.

[0021] Step 3: Extrusion processing. The aluminum rod processed in Step 1 is pushed into the mold body through a hydraulic telescopic cylinder for extrusion processing.

[0022] Step four: After the extruded profile comes out of the discharge hole, it is fed by the conveyor rollers, and then the length is set for subsequent processing such as cutting.

[0023] The technical effects and advantages provided by the present invention in the above technical solution are as follows:

[0024] 1. This invention uses a downward pressing motion to move the end of the push block close to the mating block, causing it to tilt upward. This, in turn, moves the mating block, which is movably connected to the end of the push block, upward away from the pre-set mating groove inside the moving plate that originally matched the mating block. This facilitates the translation and pulling of the moving plate, so that different molds and through holes on the moving plate correspond to each other. This makes it easier to replace the molds of the extrusion device, thereby facilitating the basic processing of aluminum profiles of different specifications.

[0025] 2. At the same time, the connecting block fixedly connected to the mold body on the rotating plate drives the mold body connected to the mounting hole by threads to rotate, thereby facilitating the removal of the mold body from the mounting hole for replacement and maintenance.

[0035] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0036] This invention provides, for example Figure 1-6The aluminum alloy profile extrusion device and process shown includes a frame 1, a side plate 2 fixedly connected to the end of the frame 1, and a hydraulic telescopic cylinder 3 fixedly installed on the end wall of the side plate 2. A mold mounting plate 4 is fixedly installed on the top of the frame 1, and a movable cavity 7 is opened inside the mold mounting plate 4. A movable plate 8 is movably connected inside the movable cavity 7, and a mounting hole 9 is opened inside the movable plate 8. A through hole 6 is opened inside the mold mounting plate 4, and the through hole 6 communicates with the mounting hole 9 and the movable cavity 7. A conveyor roller 5 is provided at the front end of the mold mounting plate 4. The device also includes:

[0037] The mold assembly 10 has a threaded groove 103 on the inner wall of the mounting hole 9, and the mold body 101 is threadedly connected to the inside of the threaded groove 103. The outer wall of the mold body 101 is provided with threads 102. A connecting block 104 is fixedly connected to the outer wall of the mold body 101, and the connecting block 104 is fixedly connected to the inner wall of the sleeve 105. The sleeve 105 moves inside the channel 106 provided inside the movable plate 8.

[0038] The limiting installation component 11 has a notch 111 on the top of the mold mounting plate 4, and a fixing rod 112 is fixedly connected to the inner wall of the notch 111. A lever 113 is movably sleeved on the outer ring of the fixing rod 112. The lever 113 is movably connected to the bottom wall of the notch 111 through a spring 114. The end of the lever 113 is movably connected to the fitting block 115. The fitting block 115 passes through the limiting groove 116 on the top of the mold mounting plate 4 and matches the fitting groove 117. The fitting groove 117 is located on the top of the moving plate 8.

[0039] The cross-section of the movable plate 8 is "I" shaped, and the side wall of the movable plate 8 is attached to and slidably connected to the inner wall of the movable cavity 7 to ensure the stability of the movement of the movable plate 8. At the same time, the connecting block 104 protruding from the mold body 101 can also move inside the movable cavity 7 and the reserved movable space.

[0040] There are five mounting holes 9, which are distributed in a line at equal intervals on the movable plate 8 so that five mold bodies 101 can be installed at the same time for switching use.

[0041] The depth of the sleeve 105 is less than the depth of the mold body 101, and there is a gap between the inner wall of the sleeve 105 and the outer wall of the mold body 101.

[0042] The outer wall of the sleeve 105 is in contact with and slidably connected to the inner wall of the channel 106. When the end of the sleeve 105 abuts against the deepest part of the channel 106, it indicates that the mold body 101 is installed and no further twisting is required.

[0043] There are two fixing rods 112, and the two fixing rods 112 are symmetrically distributed with reference to the central axis of the mold mounting plate 4, so as to ensure that the two sets of limiting mounting components 11 restrict the installation of the moving plate 8.

[0044] The interlocking block 115 is composed of three blocks. The upper block and the lower block are connected in the middle by a columnar short rod. The columnar short rod is located inside the circular hole 118 at the inclined end of the lever 113. This allows the interlocking block 115, which is movably connected to the end of the lever 113, to move synchronously when the lever 113 is turned. The inner diameter of the circular hole 118 is slightly larger than the outer diameter of the columnar short rod. There is a space for movement between the columnar short rod and the circular hole 118, which ensures that the synchronous movement of the lever 113 and the interlocking block 115 is feasible. It also facilitates the linear movement of the interlocking block 115 under the limiting position of the limiting groove 116.

[0045] One end of the spring 114 is fixedly connected to the bottom wall of the horizontal end of the lever 113, and the other end of the spring 114 is fixedly connected to the inner wall of the notch 111. The spring 114 itself presses against the lever 113, causing the lever 113 to be in a certain position. Figure 5 In the initial state shown, the mating block 115 passes through the limiting groove 116 and matches the mating groove 117 provided on the top of the moving plate 8.

[0046] There are five fitting slots 117, and the positions of the five fitting slots 117 correspond one-to-one with the positions of the five mounting holes 9.

[0047] The present invention also provides an aluminum profile extrusion process, which uses the above-mentioned aluminum alloy profile extrusion device, and the specific operation steps are as follows:

[0048] Step 1: Aluminum rod pretreatment. Lay the aluminum rods flat on the material rack with gaps between them and heat them for 3.5 hours until the temperature of the aluminum rods reaches 480 degrees Celsius, and keep them at that temperature for 1 hour.

[0049] Step 2: Mold matching. Pull out the movable plate 8 to match the mold body 101 to be used with the through hole 6, and limit the installation of the movable plate 8.

[0050] Step 3: Extrusion processing. The aluminum rod processed in Step 1 is pushed into the mold body 101 through the hydraulic telescopic cylinder 3 for extrusion processing.

[0051] Step four: After the extruded profile comes out of the discharge hole, it is fed by the conveyor roller 5, and then the length is set for subsequent processing such as cutting.

[0052] Working principle: When using an aluminum alloy profile extrusion device and process, firstly, by pressing down and moving the pusher block 113 away from the end of the fitting block 115, the downward movement of the pusher block 113 applies force to the spring 114, causing the spring 114 to deform. Moving the pusher block 113 causes the end of the pusher block 113 to tilt upwards towards the fitting block 115. The end of the pusher block 113 is movably connected to the fitting block 115. The short columnar rod in the middle of the fitting block 115 is inside the round hole 118 provided in the end of the pusher block 113. There is a space for movement between the short columnar rod and the round hole 118, so that moving the pusher block 113 can synchronously move the fitting block 115, which is movably connected to the end of the pusher block 113. And because the fitting block 115... Passing through the limiting groove 116 between the internal notch 111 of the mold mounting plate 4 and the movable cavity 7, the fitting block 115 is vertically lifted away from the pre-set fitting groove 117 at the top of the movable plate 8 that originally matched the fitting block 115. At this time, there is no limiting force between the movable plate 8 and the mold mounting plate 4, which facilitates the translation and pulling of the movable plate 8, so that different molds on the movable plate 8 correspond to the positions of the through holes 6, which facilitates the replacement of the molds of the extrusion device and facilitates the basic processing of aluminum profiles of different specifications. After the movable plate 8 is translated to the appropriate position, the spring 114 loses the manual downward force. At this time, the spring 114's own elasticity pushes against the lever 113, causing the lever 113 to be in a certain position. Figure 5 In the initial state shown, the interlocking block 115 passes through the limiting groove 116 and matches the interlocking groove 117 set on the top of the moving plate 8, completing the positional limitation between the moving plate 8 and the mold mounting plate 4. At this time, the mold body 101 is located in the central area of ​​the through hole 6, so as to facilitate the extrusion production of aluminum profiles.

[0053] When the mold body 101 on the movable plate 8 needs to be replaced, the connecting block 104 fixedly connected to the mold body 101 on the movable plate 8 can be twisted to drive the rotation of the mold body 101 which is connected to the mounting hole 9 by threads. This makes it easy to remove the mold body 101 from the mounting hole 9 for replacement and maintenance. When installing a new mold body 101, the above operation steps are repeated. The mold body 101 is aligned with the mounting hole 9 provided in the movable plate 8, and the mold body 101 is twisted to make it threadedly connected with the threaded groove 103 inside the mounting hole 9. At the same time, the sleeve 105 fixedly connected to the mold body 101 by the connecting block 104 is located inside the groove 106 inside the movable plate 8. When the end of the sleeve 105 abuts against the deepest part of the groove 106, it means that the mold body 101 is installed and no further twisting is required. This ensures the accuracy of the twisting installation of the mold body 101.

[0054] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
