Description

Technical Field

[0001] The invention relates to the technical field of micro-channel aluminum flat tube profile processing, in particular to an extrusion and coiling device used for processing micro-channel aluminum flat tube profiles. Background Art

[0002] Microchannel aluminum flat tube is a thin-walled porous flat tubular material made of refined aluminum rods through hot extrusion, surface zinc spraying anti-corrosion treatment and cooling and drying. It is mainly used in air-conditioning systems of various refrigerants as a pipeline component carrying new environmentally friendly refrigerants. According to the patent document of aluminum rod extrusion forming equipment with announcement number CN217393340U, the aluminum rod is sheared after heating, and the extrusion column needs to be pre-extruded against the aluminum rod, and the mechanical claws for grabbing the aluminum rod are withdrawn, and then the aluminum rod is pushed into the ingot barrel through the extrusion column in the aluminum rod extruder. Then, while the extrusion column pushes the aluminum rod to move in the ingot barrel, the sliding die table sends the corresponding die to the outlet side of the ingot barrel to complete the extrusion of the aluminum rod. Usually, the residual material at the end of the aluminum rod extrusion is deformed and cannot be used. The end of the aluminum rod is cut off and collected by a special shearing device to facilitate subsequent continuous smelting and use. The deformation of the end of the entire aluminum rod is obviously related to the adaptability of the entire extrusion column, the ingot barrel and the aluminum rod profile. Therefore, when extruding aluminum bars of specified sizes, the extrusion column is usually replaced and the inner diameter of the ingot holding barrel is adjusted, which affects the production efficiency of the microchannel aluminum flat tube. At the same time, according to the needs, the microchannel aluminum flat tube extruded after the mold is replaced has differences, and its hole position and hole shape will change accordingly, resulting in the need to actively adjust the components for the left and right offset of the microchannel aluminum flat tube when winding the microchannel aluminum flat tube in the subsequent preparation process, so as to clamp the two sides of the microchannel aluminum flat tube and complete a more uniform distribution of the microchannel aluminum flat tube on the roller; To this end, we propose an extrusion and coiling equipment for processing microchannel aluminum flat tube profiles.

[0008] Furthermore, motor 2 and motor 3 are fixed to one side of the winding frame by bolts respectively, one end of motor 2 and motor 3 passes through the winding frame and is fixed with a transmission gear cylinder, and the other side of the transmission gear cylinder is movably connected to the winding frame through a bearing, and sliding rods are symmetrically fixed on the inner walls of both sides of the winding frame and at the top of the transmission gear cylinder, and a movable shell is slidably connected to the sliding rods.

[0009] Furthermore, a rotating shaft block is movably connected to the inner wall of the top of the movable shell, and connecting rods are symmetrically rotatably connected on both sides of the rotating shaft block.

One end of the rotating shaft block passes through the movable shell and is fixed with a transmission tooth three by bolts, and the two sides of the transmission tooth three are respectively meshed and connected with the transmission gear cylinders on both sides.

[0010] The extrusion and coiling method for processing microchannel aluminum flat tube profiles is: Adaptation and debugging before extrusion: The roller is adapted and adjusted according to the diameter of the cut aluminum rod. The cylinder contacts the limit block on the side of the slide. While pressing the limit block, the motor drives the entire roller to rotate at equal angles through the transmission gear 2, so that the most suitable extrusion barrel is moved to the side of the ingot barrel. At the same time, the annular barrels of equal sizes are added and reduced in the ingot barrel.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1.

DETAILED DESCRIPTION

[0014] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0015] See also Figure 1-7 , the present invention provides a technical solution: Example 1: Extrusion and coiling of microchannel aluminum flat tube profile processing involves processing processes on both the head and tail sides. For hot extrusion, the aluminum rod needs to be heated to about 530°C. At the same time, the extrusion column and the mold in the extrusion process are preheated in advance, and the deformed side is cut at the end of the extrusion to facilitate uniform connection in the subsequent aluminum rod extrusion process. By adjusting the size of the extrusion column and the inner diameter of the ingot barrel, the aluminum rod can be better heated and the serious deformation problem during the extrusion of the aluminum rod can be avoided; like Figure 1 and Figure 2 As shown, the aluminum rod is conveniently heated, and the tubular rod automatically falls into the mechanical claw after being cut, and then the aluminum rod is sent to the same height as the extrusion column, and after the extrusion column contacts the aluminum rod, it is sent into the ingot holding cylinder, and along with the movement of the ingot holding cylinder, the aluminum rod is finally sent to one side of the extrusion die, and the extruded microchannel aluminum flat tube is discharged from the extrusion cover 1; To facilitate the switching of extrusion columns, Figure 3 As shown, four extrusion columns are fixed on the entire conversion mechanism 8, which respectively perform 90° rotation switching of the roller 802. The column diameters of the four extrusion columns are different, corresponding to the commonly used aluminum rod sizes for extrusion. The extrusion columns can be installed and expanded on the roller 802 later. Since the entire roller 802 is installed on the slide 801, the slide 801 is located in the slideways 7 on both sides of the extrusion cover 1, and is pushed by the cylinder 2 15 in the extrusion cover 1 to avoid affecting the rotation of the roller 802. A locking sleeve 805 is symmetrically sleeved and fixed on the roller 802, and the arc block at the end of the cylinder 2 15 is clamped with the locking sleeve 805, but not fixed, so as not to affect the rotation of the entire roller 802, and facilitate the forward and backward stretching movement of the slide 801; Considering the switching adjustment of the extrusion column on the roller 802, such as Figure 4 As shown, locking grooves 807 are evenly provided on the single-side roller 802, and the locking grooves 807 correspond to the number and position of the abutment columns 804. At the same time, a locking block 9 is slidably connected in the slide 801, and a spring 10 is installed at the bottom of the locking block 9. After the roller 802 rotates to a specific angle, the locking block 9 abutted by the spring 10 will be engaged with the locking groove 807 on the roller 802, thereby limiting the free rotation of the roller 802 in the slide 801. When the roller 802 needs to rotate, Figure 2 As shown, the cylinder 14 installed on the extrusion cover 1 is extended, and the end thereof contacts the limit block 11 located on the side of the lock block 9. Since the protrusion on the side wall of the lock block 9 is engaged with the groove on the limit block 11, the limit block 11 moving linearly pushes the lock block 9 to move downward, and at this time, the roller 802 without the limit of the lock block 9 can rotate; For the rotation of the roller 802, a transmission gear 1 806 is fixed on one side thereof by bolts. When the cylinder 2 15 pulls the slide 801 to move to the rightmost side of the extrusion cover 1, as shown in FIG. Figure 2 As shown, at this time, the transmission tooth 1 806 on the side of the slide 801 is meshed and connected with the transmission tooth 2 13 on the motor 12. At this time, in conjunction with the abutment of the cylinder 14 on the limit block 11, the motor 12 drives the transmission tooth 2 13 to rotate to realize the rotation of the roller 802 connected to the entire transmission tooth 1 806, and the rotation angle is fixed, which also realizes the adjustment of the position of the support column 804 on the fixed sleeve 803, so that the most suitable support column 804 is moved to the side of the ingot barrel, and then the hot extrusion operation of the aluminum rod is carried out; At the same time, when adjusting the inner diameter of the ingot holding barrel, the pre-prepared annular barrel is inserted, and the adjusting block 17 on the other side of the ingot holding barrel is adjusted so that the adjusting block 17 abuts against the edge of the annular barrel, thereby avoiding the problem of the aluminum rod and the annular barrel being pushed out together. At the same time, it is convenient to adjust the diameter and width of the microchannel aluminum flat tube. A slidable movable locking platform 16 is provided on one side of the entire extrusion cover 1 to facilitate the replacement of the mold during extrusion. After adjusting the inner diameter of the ingot holding barrel and replacing the diameter of the support column 804, the aluminum rod is more stable during hot extrusion, thereby reducing the deformation of the end of the aluminum rod, and also saving the time for replacing the support column 804, thereby improving the overall preparation rate of the microchannel aluminum flat tube.

[0016] Embodiment 2: Since the microchannel aluminum tube has high technical content and is extremely difficult to produce, the minimum variety has a width of 12mm and a thickness of only 1mm, but it must have 12-16 holes. Therefore, when winding the end, it is necessary to automatically clamp and adjust according to the width of the microchannel aluminum flat tube, and cooperate with the left and right moving components for active winding to achieve a more uniform distribution of the microchannel aluminum flat tube on the material roll; Since there is refrigerant medium inside the microchannel aluminum tube and atmospheric corrosion outside, it is easy to leak due to pitting corrosion. A thin layer of zinc must be sprayed on its outer surface to protect the tube wall from corrosion. For this reason, a zinc spraying station 2 is installed on the discharge side of the entire extrusion cover 1. The microchannel aluminum flat tube that has been zinc sprayed at multiple angles enters the cooling chamber 3. Due to hot extrusion, the surface temperature of the aluminum material is relatively high. Water cooling is usually used in conjunction with a water stain cleaning mechanism. Then, it passes through the drying chamber 4 for wind drying and finally arrives at the winding rack 5. like Figure 5 As shown, a material roller is installed on the winding platform 6, and the microchannel aluminum flat tube is evenly wound on the surface of the material roller after being guided by the winding frame 5. For the left and right auxiliary movement of the entire microchannel aluminum flat tube, a movable shell 22 is slidably connected to the sliding rod 19 located on the inner side of the winding frame 5, and the top of the movable shell 22 is fixedly connected to the limiting sleeve 23, and the clamping block 26 is symmetrically slidably connected in the limiting sleeve 23. The clamping block 26 is used to adjust the spacing in the limiting sleeve 23, so as to achieve clamping of the two sides of the microchannel aluminum flat tubes of different widths, and thus avoid the delay in the winding and turning of the microchannel aluminum flat tubes on both sides of the material roller due to the incompatibility of the guide components when the width of the microchannel aluminum flat tube is adjusted, resulting in the overlap of some microchannel aluminum flat tubes, and in severe cases, the stacking and deformation of the microchannel aluminum flat tubes. For this purpose, the spacing of the clamping block 26 in the limiting sleeve 23 is adjusted. The inner walls on both sides of the winding frame 5 are movably connected with the transmission gear cylinder 18, and the transmission gear three 27 installed at the bottom of the movable shell 22 is meshed with the outer wall teeth of the two transmission gear cylinders 18. Therefore, the two transmission gear cylinders 18 rotate at the same speed in opposite directions to ensure that the position of the transmission gear three 27 remains unchanged, and the transmission gear three 27 is rotated. Figure 7 As shown, the transmission gear three 27 is connected to the shaft block 24 in the movable shell 22, so after the transmission gear three 27 rotates, the entire shaft block 24 is driven to rotate, and the rotation of the shaft block 24 will drive the connecting rod 25 to move, thereby dragging the clamping block 26 connected to the connecting rod 25, changing the position of the clamping block 26 in the limiting sleeve 23, and thus clamping the two sides of the microchannel aluminum flat tubes of different widths; As for the movable shell 22 to move left and right on the slide bar 19, the two transmission gear cylinders 18 are required to rotate in the same direction and at the same speed. Motor 20 and motor 3 21 are installed on one side of the winding frame 5. Motor 20 and motor 3 21 respectively independently control the direction and speed of the two transmission gear cylinders 18. When the two transmission gear cylinders 18 rotate in the same direction, the transmission gear three 27 is driven to move to one side, and the entire movable shell 22 is moved on the slide bar 19 at the same time, thereby realizing the offset operation when the microchannel aluminum flat tube is wound.

[0017] The working process and principle of the present invention are as follows: The roller 802 is adapted and adjusted according to the diameter of the cut aluminum rod, and the cylinder 14 contacts the limit block 11 on the side of the slide 801. While pressing the limit block 11, the motor 12 drives the entire roller 802 to rotate at equal angles through the transmission gear 2 13, so that the most suitable extrusion cylinder is moved to the side of the ingot barrel, and at the same time, the annular cylinders of equal size are added and reduced in the ingot barrel, and the adjustment block 17 is adjusted to adjust the telescopic side of the ingot barrel, so as to change the inner diameter of the entire ingot barrel and adapt it to the aluminum rod. While the mechanical claw feeds, the extrusion column in the extrusion cover 1 pushes the aluminum rod into the ingot barrel, and then the mold is installed on the movable locking table 16 to start the microchannel aluminum flat tube extrusion molding; According to the width of the formed microchannel aluminum flat tube, the motor 20 and the motor 3 21 rotate in opposite directions, driving the transmission gear 3 27 in the transmission gear cylinder 18 to rotate in place, and the rotation of the transmission gear 3 27 drives the shaft block 24 to rotate, and the connecting rod 25 located on the shaft block 24 pulls the clamping block 26 in the limit sleeve 23 to move, changing the spacing of the clamping block 26 and adapting to the width of the microchannel aluminum flat tube; The deformed end of the microchannel aluminum flat tube extruded from the discharge port of the extrusion hood 1 is cut, and then enters the zinc spraying hood for zinc spraying treatment, and then passes through the cooling chamber 3 and the drying chamber 4 in sequence for surface treatment of the microchannel aluminum flat tube, and then is limited by the clamping block 26 in the limiting sleeve 23 and finally wound on the surface of the material roll on the winding table 6, and the motor 2 20 and the motor 3 21 are rotated to carry out the winding of the microchannel aluminum flat tube.
