Description

Technical Field

[0001] This invention relates to the field of aluminum profile production, and more specifically, to a cold extrusion forming equipment for aluminum alloy profiles. Background Technology

[0002] Cold extrusion forming of aluminum alloy profiles is a plastic processing method that uses a press for extruding metal to apply enormous pressure to an aluminum alloy billet placed in a die cavity, causing it to "extrude" from specific holes in the die, thereby obtaining a profile with the desired cross-sectional shape. During the cold extrusion of aluminum alloys, the metal undergoes intense plastic deformation within the die, resulting in extremely high unit extrusion pressure. Poor lubrication can lead to surface scratches on the workpiece, excessive die wear, and even workpiece seizing. Currently, the industry generally employs a lubricating layer on the outside of the billet for lubrication. The methods for establishing this lubricating layer include: First, surface pretreatment to establish a carrier layer (phosphate treatment / oxalate treatment); Second, lubricant coating (saponification treatment). While this method can create a lubricating layer on the surface of the billet, effectively coping with the extreme conditions during cold extrusion, the pre-treated lubricating layer is very susceptible to damage during billet transportation and loading. Scratches, bumps, or contamination during transportation and loading can disrupt the continuity and integrity of the lubricating film, resulting in the loss of local protection during extrusion, thus causing product defects and mold damage. If a precision transportation method similar to that used for "semi-finished precision parts" is adopted for the billet, it will lead to excessively high costs for the entire production line. Summary of the Invention

[0003] In view of the problems existing in the prior art, the purpose of this invention is to provide a cold extrusion forming equipment for aluminum alloy profiles.

[0004] To solve the above problems, the present invention adopts the following technical solution.

It also includes a feeding assembly, which includes a support base, multiple feeding rollers rotatably connected to the upper end of the support base, a drying section fixed to the upper end of the support base, and two lifting sections symmetrically arranged inside the support base.

[0006] Furthermore, a drying section 2 is fixedly connected to one side of the movable seat 2, and a vibration table is connected to the lower end of the support seat.

[0007] Furthermore, the lifting part includes a lifting seat slidably connected inside the support base, two transmission rollers rotatably connected inside the lifting seat, a motor fixed to one side of the lifting seat and connected to one of the transmission rollers, a limiting seat fixed to one side of the lifting seat, and a hydraulic cylinder fixed inside the support base with its telescopic end connected to the bottom of the lifting seat. The two transmission rollers are connected by a transmission component.

[0008] Furthermore, the pressure application unit includes a movable seat slidably connected to the guide frame, a slide rail fixed to one side of the movable seat, a slide block slidably connected to the slide rail, a hydraulic cylinder fixed to the upper end of the slide rail, and a feeding and pressure application component fixed to one side of the slide block, wherein the telescopic end of the hydraulic cylinder is connected to the slide block.

[0009] Furthermore, a lead screw is rotatably connected to the lower end of the extension frame, and a second motor is fixedly connected to one side of the extension frame. The output shaft of the second motor is connected to the lead screw. A second scraper is slidably connected to one side of the movable seat, and the second scraper is screwed to the outside of the lead screw.

[0010] Furthermore, it also includes a material leveling assembly, which includes a top plate fixed to one side of the movable seat two and located above the scraper one, a plurality of columns fixed to one side of the top plate, an ultrasonic transducer fixed to one end and the outer surface of the columns, and an ultrasonic generator fixed to one side of the movable seat two and connected to the ultrasonic transducer.

[0011] Furthermore, multiple columns are inclined and fixed to one side of the top plate, and the lower end of the top plate is connected to the upper end of the scraper through a buffer plate.

[0012] Furthermore, a cleaning assembly is connected to the other side of the guide frame, and the cleaning assembly includes a fixed seat fixed to one side of the guide frame, a hydraulic cylinder four fixed to one side of the fixed seat, a guide rod two movably inserted into the fixed seat, a movable seat three fixed to one end of the guide rod two and connected to the telescopic end of the hydraulic cylinder four, an air outlet one opened on one side of the movable seat three, a cleaning roller rotatably connected to one side of the movable seat three, and a motor three fixed to one side of the movable seat three and whose output shaft is connected to the cleaning roller.

[0013] Furthermore, the movable seat three has an air outlet groove inside, and an air outlet two is provided on the inner top wall of the air outlet groove. An air duct interface is provided on one side of the movable seat three, and the air duct interface is connected to the air outlet one and the air outlet two.

[0014] Furthermore, a combing part for cleaning the cleaning roller is fixedly connected to the inner wall of the air outlet groove, and the air outlet end of the second air outlet faces the combing part.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) This solution is equipped with a lubrication component, which transports the pre-treated billet with a carrier layer to the pressure mold entry station. The carrier layer is an inorganic salt grown on the metal surface, which has high hardness and good anti-friction properties during transportation. Compared with the billet after saponification, the transportation is safer and cleaner. Then, the lubricant is discharged to the surface of the billet through the discharge section, and the lubricant is evenly scraped by the scraper. The lubricating slurry is pressed into the micropores of the chemical conversion film and the scratches generated during transportation, filling the damage caused by transportation and greatly enhancing the final lubrication effect. Even if there are slight scratches on the base layer of the billet, they can be covered and repaired by the lubricant. This ensures a good lubrication effect, so there is no need to carry out precision transportation of the billet, which reduces the cost of upgrading the entire production line.

[0016] (2) This solution is equipped with a lead screw and scraper II. The lead screw drives scraper II to reciprocate. The reciprocating motion of scraper II pre-scrapes the lubricant on the outer surface of the blank. The reciprocating scraper, with its dynamic and shearing action, can forcefully squeeze the lubricant mixture into the micropores of each scratch, pit and phosphate film, ensuring the firmness of the basic filling. After being treated by scraper II, scraper I is used to treat it. It moves with a fixed gap, uniform pressure and speed to smooth out all the wavy lines, scratches and other marks left by the previous pre-scraping, eliminating the risk of local lubrication failure caused by "pits" and "missing" lubricant layers, and reducing the probability of surface scratches and cracks in the product.

[0017] (3) This solution is equipped with a uniform material assembly. The ultrasonic energy generated by the uniform material assembly can reduce the viscosity of the slurry, making it flow better when it contacts the scraper and eliminating the knife marks generated by the scraper. In addition, the ultrasonic waves can help to uniformly disperse the powder particles in the lubricating slurry in the form of individual particles, and can also expel the microbubbles in the lubricating slurry. At the same time, the ultrasonic waves can enhance the penetration and wetting ability of the lubricating mixture in the micropores and surface scratches of the phosphating film, making it easier to flow in and fill every surface defect and pore, and maximizing the contact area with the substrate.

[0018] (4) This solution is equipped with a cleaning component. The cleaning roller cleans the outer surface of the billet, which helps the billet and the lubricating slurry to achieve the maximum physical adsorption and chemical bonding. At the same time, the cleaning can expose the real scratches and pits on the surface of the billet, so that the lubricating slurry can directly fill these defects instead of filling on the contaminants, thereby forming a continuous protective layer.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0022] Please see Figures 1 to 8 A cold extrusion forming equipment for aluminum alloy profiles includes a press 2, a frame 1 fixed to the upper end of the press 2, a support part 4, a mold 3 fixed to one side of the support part 4, a guide frame 6 with both ends connected to the support part 4 and the press 2 respectively, and a pressure application part 5 slidably connected to the guide frame 6 and connected to the output end of the press 2. It also includes a feeding assembly 7, which includes a support base 72, a plurality of feeding rollers 73 rotatably connected to the upper end of the support base 72, a drying section 74 fixed to the upper end of the support base 72, and two lifting sections symmetrically arranged inside the support base 72. The guide frame 6 is connected to a lubrication assembly 8 on one side, and the lubrication assembly 8 includes a fixed plate 81 fixed to one side of the guide frame 6, a hydraulic cylinder 3 82 fixed to one side of the fixed plate 81, a guide rod 1 83 movably inserted into the fixed plate 81, a movable seat 2 84 fixed to one end of the guide rod 1 83 and connected to the telescopic end of the hydraulic cylinder 3 82, an extension frame 841 fixed to one side of the movable seat 2 84, a discharge part 842 opened at the lower end of the extension frame 841, an inlet port 843 opened on one side of the movable seat 2 84 and connected to the discharge part 842, and a scraper 1 85 fixed to one side of the movable seat 2 84.

[0023] A drying section 86 is also fixedly connected to one side of the movable seat 84, and a vibration table 71 is connected to the lower end of the support seat 72.

[0024] The lifting unit includes a lifting seat 75 slidably connected inside the support seat 72, two transmission rollers 76 rotatably connected inside the lifting seat 75, a motor 77 fixed to one side of the lifting seat 75 and connected to one of the transmission rollers 76, a limiting seat 78 fixed to one side of the lifting seat 75, and a hydraulic cylinder 79 fixed inside the support seat 72 with its telescopic end connected to the bottom of the lifting seat 75. The two transmission rollers 76 are connected by a transmission component.

[0025] The pressure application part 5 includes a movable seat 51 slidably connected to the guide frame 6, a slide rail 52 fixed to one side of the movable seat 51, a slide block 54 slidably connected to the slide rail 52, a hydraulic cylinder 53 fixed to the upper end of the slide rail 52, and a feeding pressure member 55 fixed to one side of the slide block 54, and the telescopic end of the hydraulic cylinder 53 is connected to the slide block 54.

[0026] By adopting the above technical solution, the vibration table 71 is fixed on the lifting platform, and the feeding interface 843 is connected to the feeding part. After the billet is transported to the support seat 72 and the billet contacts the feeding roller 73, the lifting platform is raised and the billet is made coaxial with the feeding port in the mold 3. At this time, the hydraulic cylinder 79 is extended and the lifting seat 75 is lifted from the support seat 72, so that the transmission roller 76 on the lifting seat 75 contacts the billet. The motor 77 is controlled to work and drive the transmission roller 76 to rotate, which in turn drives the billet to rotate. The hydraulic cylinder 82 is extended and pushes the movable seat 84 towards the billet, so that the discharge part 842 reaches above the billet. At the same time, the scraper 85 can contact the outer surface of the billet. The feeding part pumps the lubricating slurry into the discharge part 842, and the lubricating slurry flows out from the discharge part 842. 42 is discharged and falls onto the surface of the billet; when the billet rotates, scraper 85 can smooth the lubricating slurry on the surface of the billet, ensuring the uniformity of the lubricating layer, pressing the lubricating slurry into the micropores of the chemical conversion film and the scratches generated during transportation, filling the damage caused by transportation, and greatly enhancing the final lubrication effect; even if there are slight scratches on the base layer of the billet, they can be covered and repaired by the lubricant; ensuring a good lubrication effect, so that the billet does not need to be transported precisely, reducing the cost of upgrading the entire production line; the lubricating slurry can be a composition of solid lubricating powder (such as molybdenum disulfide, graphite, polymer powder, etc.) + liquid carrier (solvent, water) + polymer resin or adhesive (such as acrylic resin, epoxy resin, cellulose derivatives, etc.) dissolved in the liquid carrier. The lubricant on the outer surface of the billet can be dried by the drying section 74 and the drying section 86. The drying section 74 and the drying section 86 can use drying methods such as hot air drying and infrared drying, which are mature existing technologies and will not be described in detail here. After drying, the hydraulic cylinder 79 descends and resets, and makes the billet contact the feeding roller 73. The hydraulic cylinder 53 works to drive the slide 54 to slide along the slide rail 52, so that the slide 54 and the feeding pressure component 55 move downward. The feeding pressure component 55 and the billet are on the same axis. The press 2 is controlled to work and drive the movable seat 51 and the feeding pressure component 55 to move towards the billet. One end of the feeding pressure component 55 contacts one end of the billet and pushes the billet into the mold 3, so that the billet is fed into the mold 3 and cold extruded.

[0027] like Figure 6 As shown, the lower end of the extension frame 841 is rotatably connected to a lead screw 88, and a motor 87 is fixedly connected to one side of the extension frame 841. The output shaft of the motor 87 is connected to the lead screw 88. A scraper 89 is slidably connected to one side of the movable seat 84, and the scraper 89 is screwed to the outside of the lead screw 88.

[0028] By adopting the above technical solution, the motor 87 drives the lead screw 88 to rotate, and the rotation of the lead screw 88 drives the scraper 89 to move. Before the scraper 85 smooths the lubricating slurry, the reciprocating motion of the scraper 89 can pre-scrape the lubricant on the outer surface of the blank. The reciprocating scraper 89, with its dynamic and shearing action, can forcefully squeeze the lubricating mixture into the micropores of each scratch, pit, and phosphate film, ensuring the firmness of the basic filling. After being treated by the scraper 89, the scraper 85 is used to treat it with a fixed gap, uniform pressure, and speed, smoothing out all the wavy lines and scratches left by the previous pre-scraping, eliminating the risk of local lubrication failure caused by "pits" or "missing" lubricating layers, and reducing the probability of surface scratches and cracks on the product.

[0029] like Figures 6-8 As shown, it also includes a material leveling component 9, which includes a top plate 91 fixed to one side of the movable seat 84 and located above the scraper 85, a plurality of columns 93 fixed to one side of the top plate 91, an ultrasonic transducer 94 fixed to one end and the outer surface of the column 93, and an ultrasonic generator 95 fixed to one side of the movable seat 84 and connected to the ultrasonic transducer 94.

[0030] Multiple columns 93 are inclined and fixed on one side of the top plate 91, and the lower end of the top plate 91 is connected to the upper end of the scraper 85 through a buffer plate 92.

[0031] By adopting the above technical solution, when the scraper 85 scrapes the lubricating slurry on the outside of the blank, the ultrasonic generator 95 sends a signal to the ultrasonic transducer 94, and the ultrasonic transducer 94 outputs ultrasonic waves to the lubricating slurry, reducing the viscosity of the slurry and improving its fluidity when it contacts the scraper 85, thus eliminating the knife marks generated by the scraper 85. In addition, the ultrasonic waves also help to uniformly disperse the powder particles in the lubricating slurry in the form of individual particles, and can also drive out the microbubbles in the lubricating slurry. At the same time, the ultrasonic waves can enhance the penetration and wetting ability of the lubricating slurry in the micropores of the phosphating film and surface scratches, making it easier to flow in and fill every surface defect and pore, maximizing the contact area with the substrate.

[0032] like Figure 2 , Figure 9 and Figure 10As shown, the other side of the guide frame 6 is also connected to a cleaning component 10, and the cleaning component 10 includes a fixed seat 101 fixed to one side of the guide frame 6, a hydraulic cylinder 103 fixed to one side of the fixed seat 101, a guide rod 102 movably inserted into the fixed seat 101, a movable seat 104 fixed to one end of the guide rod 102 and connected to the telescopic end of the hydraulic cylinder 103, an air outlet 105 opened on one side of the movable seat 104, a cleaning roller 106 rotatably connected to one side of the movable seat 104, and a motor 107 fixed to one side of the movable seat 104 and whose output shaft is connected to the cleaning roller 106.

[0033] The movable seat 104 has an air outlet groove 108 inside, and an air outlet 1081 is provided on the inner top wall of the air outlet groove 108. An air duct interface is provided on one side of the movable seat 104, and the air duct interface is connected to the air outlet 105 and the air outlet 1081.

[0034] The inner wall of the air outlet 108 is fixedly connected to a combing part 109 for cleaning the cleaning roller 106, and the air outlet end of the second air outlet 1081 faces the combing part 109.

[0035] By adopting the above technical solution, the pipeline of the air supply equipment is connected to the air duct interface. Before the lubricating slurry is discharged from the discharge section 842 and falls onto the surface of the billet, the hydraulic cylinder four 103 extends and drives the movable seat three 104 to move towards the billet. The motor three 107 works to drive the cleaning roller 106 to rotate. The cleaning roller 106 cleans the surface of the billet, and at the same time, the air outlet one 105 can blow the surface of the billet. The combing part 109 can scrape the bristles of the cleaning roller 106, and the air outlet two 1081 blows out the impurities scraped off by the combing part 109 in the air outlet groove 108. By cleaning the outer surface of the billet, it helps the billet and the lubricating slurry to form the maximum physical adsorption and chemical bonding. At the same time, cleaning can expose the real scratches and pits on the surface of the billet, so that the lubricating slurry can directly fill these defects instead of filling on the contaminants, thereby forming a continuous protective layer.

[0036] Operating Instructions: Fix the vibrating table 71 onto the lifting platform, connect the feeding interface 843 to the feeding unit, transport the billet to the support base 72, and after the billet contacts the feeding roller 73, the lifting platform rises and makes the billet coaxial with the feeding port in the mold 3; at this time, control the hydraulic cylinder 2 79 to extend and lift the lifting base 75 from the support base 72, so that the transmission roller 76 on the lifting base 75 contacts the billet; control the motor 1 77 to work and drive the transmission roller 76 to rotate, which in turn drives the billet to rotate; control the hydraulic cylinder 4 103 to extend and drive the movable base 3 104 to move towards the billet, and the motor 3 107 to work and drive the cleaning roller 106 to rotate, which cleans the surface of the billet, while the air outlet 105 blows the surface of the billet; the combing part 109 combs the bristles of the cleaning roller 106, and the air outlet 1081 blows the surface of the billet. The impurities scraped off by the combing part 109 in the air outlet duct 108 are blown out; the hydraulic cylinder 3 82 is extended and pushes the movable seat 2 84 towards the billet, so that the discharge part 842 reaches above the billet, and at the same time the scraper 1 85 can contact the outer surface of the billet. The feeding part pumps the lubricating slurry into the discharge part 842, and the lubricating slurry is discharged from the discharge part 842 and falls on the surface of the billet; the motor 2 87 drives the lead screw 88 to rotate, and the rotation of the lead screw 88 can drive the scraper 2 89 to move. Before the scraper 1 85 scrapes the lubricating slurry, the reciprocating motion of the scraper 2 89 can pre-scrape the lubricating slurry on the outer surface of the billet. The reciprocating scraper 2 89, with its dynamic and shearing action, can forcefully squeeze the lubricating slurry into the micropores of each scratch, pit and phosphate film. The scraper 1 85 can scrape the lubricating slurry on the surface of the billet.
