Description

Technical Field

[0001] This utility model relates to the field of aluminum extrusion press technology, and in particular to an aluminum extrusion press with a cleaning device. Background Technology

[0002] An aluminum extrusion press is a device used to produce aluminum materials of various shapes and sizes. Its main function is to shape aluminum alloy materials into the required shapes and sizes through extrusion.

[0003] The filter material extrusion press mainly consists of three parts: a heating unit, an extrusion unit, and a cooling unit. After the aluminum profile is heated to a deformable temperature, it is placed into the extrusion unit for extrusion molding. The extrusion cylinder of the extrusion unit is also one of the components that easily adheres to residual materials or dirt. According to the authorized publication number "CN207615385U", an aluminum extrusion press is disclosed, including an extrusion drive assembly, an aluminum extrusion cylinder, an aluminum heating device, an aluminum extrusion device, and a base plate. The extrusion drive assembly includes an extrusion drive motor, an extrusion drive screw, a guide shaft, a motor fixing plate, and a screw fixing plate. The extrusion drive motor is connected to the motor fixing plate by screws. The output end of the extrusion drive motor is connected to the extrusion drive screw via a coupling, and the other end of the extrusion drive screw is rotatably connected to the screw fixing plate. This utility model has an internal aluminum heating device to prevent the rapid heat dissipation of the extrusion cylinder from causing the aluminum alloy temperature to drop too quickly, which would make it difficult to form during the extrusion process.

[0004] Currently, for some small hardware aluminum parts, during processing, aluminum rods of different shapes are cut into parts of different thicknesses or sizes. These aluminum rods are then formed by an extrusion press. However, during the extrusion process, material residue is left inside the extrusion cylinder. Since most extrusion cylinders are integral cylindrical structures, if the depth is slightly large, it is difficult to completely clean the bottom of the extrusion cylinder, causing material adhesion and hindering subsequent processing. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by proposing an aluminum extrusion machine with a cleaning device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an aluminum extrusion machine with a cleaning device, including a base, a support frame provided above the base, the support frame having a U-shaped structure, a plate seat fixed above the base, the plate seats being symmetrically distributed along both sides of the base, side plates being inserted into the plate seats, and an extrusion cylinder being fixed between the side plates distributed along both sides.

[0007] A mold plate is attached to the lower end of the extrusion cylinder. The surface of the mold plate is provided with extrusion holes of different shapes. Extension plates are symmetrically distributed and fixed on both sides of the mold plate. A hydraulic cylinder is provided at the lower end of the extension plate.

[0008] The lower end of the hydraulic cylinder is fixed to the surface of the base by screws. The hydraulic cylinder has a piston rod for extension and retraction inside, and the end of the piston rod is located below the extension plate.

[0009] Preferably, a hydraulic cylinder 2 is provided through the upper end of the support frame, and a piston rod 2 for extension and retraction is provided inside the hydraulic cylinder 2. The outer wall of the hydraulic cylinder 2 is fixedly installed to the surface of the support frame through a bracket.

[0010] Preferably, an extrusion plate is fixedly installed at both ends of the piston rod of the second hydraulic cylinder, and the diameter of the extrusion plate does not exceed the inner diameter of the extrusion cylinder.

[0011] Preferably, the extrusion cylinder has a split structure, consisting of a left half and a right half, with mounting plates fixed on both sides of the left and right half.

[0012] Preferably, both mounting plates distributed along one side are internally provided with fastening bolts, and the other end of the fastening bolt is threaded with a nut, which is tightly fitted against the surface of the corresponding mounting plate.

[0013] Preferably, the lower end of the extension plate is fixed with a rod sleeve, and the inside of the rod sleeve is slidably sleeved with the piston rod of the hydraulic cylinder.

[0014] Preferably, the piston rod of the hydraulic cylinder has a groove at one end, and a locking pin is slidably sleeved inside the groove. The end of the locking pin has a curved structure, and a spring is provided inside the groove. The two ends of the spring are fixedly installed to the inner wall of the groove and the surface of the locking pin, respectively.

[0015] Preferably, the inner wall of the sleeve is provided with an arc-shaped groove, and the end of the locking pin is tightly fitted against the inner wall of the arc-shaped groove.

[0016] The design scheme proposed in this utility model has the following beneficial effects in application:

[0017] 1. This solution divides the extrusion cylinder into a left half and a right half, which are fixed on both sides by mounting plates and fastening bolts. When cleaning is required, the extrusion cylinder can be separated in half by simply removing the bolts, forming a completely open working surface. This open structure allows operators to directly contact the inner wall of the cylinder and use tools for all-round cleaning, effectively avoiding mold blockage or product contamination caused by residue accumulation.

[0018] 2. As described in 1, the piston rod of hydraulic cylinder one retracts, causing the mold plate to move down and creating sufficient operating space. Workers can directly pull and replace mold plates with different extrusion holes. The sleeve and piston rod adopt an automatic locking structure of spring pin and arc groove. During installation, simply push the sleeve in to complete the self-locking through the curved surface extrusion of the pin. During disassembly, it can be separated by simply pulling.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Example 1

[0027] Reference Figures 1-5 An aluminum extrusion press with a cleaning device includes a base 1, a support frame 11 on the top of the base 1, the support frame 11 having a U-shaped structure, a plate seat 12 fixed on the top of the base 1, the plate seat 12 being symmetrically distributed along both sides of the base 1, side plates 13 being inserted into the inside of the plate seat 12, and an extrusion cylinder 14 being fixed between the side plates 13 distributed along both sides. The plate seat 12 can insert and position the side plates 13 connected to both sides of the extrusion cylinder 14 during the aluminum extrusion process, ensuring the stable assembly of the extrusion cylinder 14 based on the base 1.

[0028] A mold plate 18 is attached to the lower end of the extrusion cylinder 14. The surface of the mold plate 18 is provided with extrusion holes 19 of different shapes. Extension plates 17 are symmetrically distributed and fixed on both sides of the mold plate 18. A hydraulic cylinder 16 is provided at the lower end of the extension plate 17. The extrusion holes 19 on the mold plate 18 can form aluminum rods of different specifications through the extrusion holes 19 of different shapes when the aluminum base material is extruded from the extrusion cylinder 14.

[0029] The lower end of the hydraulic cylinder 16 is fixed to the surface of the base 1 by screws. The hydraulic cylinder 16 is equipped with a piston rod for extension and retraction. The end of the piston rod is located below the extension plate 17. By extending and retracting the piston rod of the hydraulic cylinder 16, the mold plate 18 and the extrusion cylinder 14 can be stably fitted together. When the mold plate 18 is replaced, it can be moved down to make room for installation and disassembly.

[0030] It should be further explained that a hydraulic cylinder 2 is installed through the upper end of the support frame 11. The hydraulic cylinder 2 has a piston rod 2 for extension and retraction inside. The outer wall of the hydraulic cylinder 2 is fixedly installed to the surface of the support frame 11 through a bracket. The hydraulic cylinder 2 can provide sufficient power when the aluminum material is extruded.

[0031] It should be further noted that the piston rod of hydraulic cylinder 2 is fixedly installed with extrusion plates 21 at both ends. The diameter of extrusion plates 21 does not exceed the inner diameter of extrusion cylinder 14, and the outer diameter of extrusion plates 21 is smaller than the inner diameter of extrusion cylinder 14, so as to ensure that extrusion plates 21 can normally enter the interior of extrusion cylinder 14 when extruding aluminum material.

[0032] It should be further explained that the extrusion cylinder 14 has a split structure, consisting of a left half and a right half. Mounting plates 3 are fixed on both sides of the left and right half. By splitting the extrusion cylinder 14 in half, it can be separated into two halves during cleaning, forming an open shape, thereby allowing for better cleaning of all parts of the extrusion cylinder 14.

[0033] It should be further explained that fastening bolts 32 are installed through the interior of the two mounting plates 3 distributed along one side. The other end of the fastening bolts 32 is threaded with nuts 33. The nuts 33 are tightly fitted against the surface of the corresponding mounting plate 3. Several fastening bolts 32 are arranged vertically along one side. With the corresponding nuts 33, the half-splitting of the extrusion cylinder 14 can be stabilized and sufficient support strength can be achieved when aluminum is extruded in the extrusion cylinder 14.

[0034] It should be further explained that a rod sleeve 4 is fixed at the lower end of the extension plate 17. The inside of the rod sleeve 4 is slidably sleeved with the piston rod of the hydraulic cylinder 16. Through the docking of the rod sleeve 4 and the piston rod, the mold plate 18 and the hydraulic cylinder 16 can be quickly docked.

[0035] It should be further explained that a groove 41 is provided at one end of the piston rod of the hydraulic cylinder 16. A locking pin 42 is slidably sleeved inside the groove 41. The end of the locking pin 42 has a curved surface structure. A spring 43 is provided inside the groove 41. The two ends of the spring 43 are fixedly installed to the inner wall of the groove 41 and the surface of the locking pin 42, respectively. The spring 43 can ensure the stable extension and repositioning of the locking pin 42. The curved surface at the end of the locking pin 42 can better cooperate and move during the extrusion process.

[0036] It should be further explained that an arc-shaped groove 44 is provided on the inner wall surface of the sleeve 4. The end of the locking pin 42 is tightly fitted against the inner wall surface of the arc-shaped groove 44. When the sleeve 4 and the piston rod need to be installed, the sleeve 4 and the piston rod are connected to achieve positioning. As the sleeve 4 is continuously connected to the piston rod, it will contact the curved surface of the end of the locking pin 42 and form a squeezing effect, causing the locking pin 42 to compress the spring 43 and enter the interior of the groove 41. Thus, the sleeve 4 and the piston rod are completely connected. At this time, the position of the locking pin 42 corresponds to the position of the arc-shaped groove 44. Through the reset effect of the spring 43, the locking pin 42 can spring into the interior of the arc-shaped groove 44 and form a compacting effect. During disassembly, by pulling, the locking pin 42 and the inner arc surface of the arc-shaped groove 44 can slide and squeeze to separate.

[0037] In practice

[0038] In this scheme, hydraulic cylinder 2 drives extrusion plate 21 to move downward through the extension and retraction of piston rod 2. The outer diameter of extrusion plate 21 is smaller than the inner diameter of extrusion cylinder 14, ensuring that it can smoothly enter the extrusion cylinder 14. After the aluminum base material is put into the extrusion cylinder 14, extrusion plate 21 applies pressure to the aluminum material under the push of hydraulic cylinder 2, forcing the aluminum material to flow towards mold plate 18. The surface of mold plate 18 is provided with extrusion holes 19 of different shapes. Under high pressure, the aluminum material is formed into aluminum rods of different specifications through extrusion holes 19. Mold plate 18 is connected to hydraulic cylinder 16 through extension plate 17. The piston rod of hydraulic cylinder 16 pushes extension plate 17 upward, so that mold plate 18 and the lower end of extrusion cylinder 14 are tightly fitted, ensuring no material leakage during extrusion. Support frame 11 and plate seat 12 provide support for the top and side of extrusion cylinder 14, respectively. Side plate 13 is inserted into plate seat 12 to further stabilize the position of extrusion cylinder 14 and ensure the stability of extrusion process.

[0039] When it is necessary to replace the mold plate 18 to adapt to different aluminum forming requirements, the piston rod of the hydraulic cylinder 16 retracts downward, causing the extension plate 17 and the mold plate 18 to move downward, creating sufficient space for disassembly. The mold plate 18 is fixedly connected to the sleeve 4 through the extension plate 17. The sleeve 4 is slidably sleeved on the piston rod of the hydraulic cylinder 16. A locking pin 42 is provided in the groove 41 at the end of the piston rod. The locking pin 42 is held outward by the spring 43. The arc groove 4 on the inner wall of the sleeve 4... 4. The end curved surface of the locking pin 42 is engaged with the sleeve 4. When the sleeve 4 is fitted into the piston rod, the locking pin 42 is squeezed back into the groove 41 until the arc groove 44 is aligned with the locking pin 42. The spring 43 pushes the locking pin 42 into the arc groove 44 to achieve quick locking. When disassembling, the sleeve 4 is pulled by external force, the locking pin 42 slides along the curved surface of the arc groove 44 and compresses the spring 43 to achieve separation. This design makes the replacement of the mold plate 18 more efficient, while ensuring its stability during the extrusion process.

[0040] The extrusion cylinder 14 adopts a split structure, consisting of a left half and a right half, which are fixed on both sides by mounting plates 3 and fastening bolts 32. During cleaning, loosening the nuts 33 and removing the fastening bolts 32 can separate the extrusion cylinder 14 into two halves, completely exposing the internal space and facilitating the removal of residual aluminum shavings or impurities. Multiple fastening bolts 32 are distributed on the upper and lower parts of the mounting plate 3 to ensure that the extrusion cylinder 14 has sufficient structural strength during high-pressure extrusion. The support frame 11 and the plate seat 12 continue to support the extrusion cylinder 14 during cleaning. The side plate 13 can be disassembled or cleaned separately. The piston rod of the hydraulic cylinder 16 can be fully retracted to avoid interfering with the cleaning operation.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
