Description

Technical Field

[0001] The invention relates to the technical field of aluminum profile extrusion equipment, and in particular to an aluminum profile automatic extrusion equipment. Background Art

[0002] Aluminum profiles have a series of excellent properties. Among the applications of metal materials, the application of aluminum is second only to that of steel. Aluminum profile extrusion equipment generally includes a heating mechanism, an extruder, a conveying and cutting mechanism, and an annealing and cooling mechanism. The specific production process is as follows: the heating mechanism heats the aluminum billet (constant temperature 480°), cuts it into small sections, and transfers the cut aluminum billet to the extrusion station of the extruder equipment to extrude into long strip profiles. The extruded profiles are conveyed and cut by the conveying and cutting mechanism to form finished profiles, and finally cooled by the annealing and cooling mechanism.

[0003] Existing aluminum profile extrusion equipment has many technical defects when in use. First, after the extrusion is completed, the flat die is tightly filled with residual materials inside and cannot be cleaned directly. The flat die needs to be disassembled and heated at high temperature, and then the residual materials need to be manually removed, which is time-consuming and labor-intensive, and has low work efficiency. Second, when the aluminum profile is cut with a cutting knife, since the aluminum profile has not been cooled and the structural strength is weak, the conventional one-size-fits-all approach is likely to cause deformation and cracking of the incision area, reduce the cutting integrity, and shorten the service life of the cutting knife. Third, when cutting the aluminum profile, on the one hand, due to the long structure and weak structural strength of the aluminum profile and the lack of fixing measures, the cutting position is easily offset and the incision is oblique. On the other hand, before the aluminum profile is transported to the annealing mechanism, it is easy to bump and deform during the transportation and transfer process, affecting the subsequent annealing cooling and straightening process.

[0004] To sum up, considering that the existing facilities cannot meet the work needs, we propose an automatic extrusion equipment for aluminum profiles. Summary of the invention

[0028] The present invention provides an aluminum profile automatic extrusion equipment through improvement, which has the following significant improvements and advantages compared with the prior art:

[0029] First, start the servo motor to drive the driving gear to rotate. After a series of transmissions, the inner extension seat is driven to make slow circular motion. When the annular cutting knife on the inner extension seat approaches the aluminum profile, turn on the cutting motor, and the connecting shaft drives the annular cutting knife to rotate at high speed, causing the annular cutting knife to make an arc motion around the aluminum profile while cutting the aluminum profile at different depths, reducing the contact strength during cutting, increasing the cutting contact time and point, ensuring the cutting quality, avoiding deformation and cracking of the incision area, and extending the service life of the cutter.

[0030] Start the screw motor to drive one set of long screws to rotate, and cause the other set of long screws to rotate synchronously through the transmission of the chain. The connecting arms on the two sets of long screws move downward, causing the middle flat mold to move downward until the flat mold moves to the middle and lower part of the mold lifting bracket, close to and aligned with the unloading seat, achieving the effect of automatic positioning, with a high degree of automation, and preparing for residual material cleaning.

[0031] Start the punching cylinder and use the punching head to hit the aluminum profile unloading die, causing the aluminum profile unloading die to move linearly in the die guide port. The aluminum profile unloading die exerts pressure on the residual material in the extrusion groove, causing the entire residual material in the flat die to move to the left. After multiple hits, the entire residual material in the flat die is guided out from the connecting groove, thereby achieving the effect of automatically removing the residual material, solving the problem of time-consuming, labor-intensive and low working efficiency of the prior art.

[0032] The lower end of the positive pressure wheel cooperates with the bottom of the material receiving channel to press the bottom of the aluminum profile. The side wheel surfaces of the two sets of side pressure wheels cooperate with the side walls of the material receiving channel to press the two side edges of the aluminum profile. On the one hand, it ensures that the aluminum profile is straightened during transportation to avoid bumps and deformation; on the other hand, it fully limits and guides the aluminum profile to avoid deviation during cutting.

DETAILED DESCRIPTION

[0047] 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. Embodiment 1

[0048] like Figure 1-10 As shown, this embodiment provides an automated extrusion equipment for aluminum profiles, including an equipment body 1, a fixing plate 2 is vertically installed on the left side of the upper end surface of the equipment body 1, which plays a role of installation and fixing, a hydraulic cylinder 3 is horizontally arranged on the inner side surface of the fixing plate 2, and an extrusion rod 4 is extended upward inside the hydraulic cylinder 3.

[0049] A guide trough 5 is installed at the middle position of the upper end surface of the equipment body 1. The inner surface of the guide trough 5 is smooth and heat-resistant. An aluminum bar 6 aligned with the extrusion rod 4 is placed horizontally in the guide trough 5. Figure 2 shown.

[0050] Furthermore, the right end of the equipment body 1 is connected to a support seat 7, and a mold lifting bracket 10 is installed upward inside the support seat 7. Two groups of through holes 56 are opened on the left and right end surfaces of the mold lifting bracket 10, and the through holes 56 play a role in avoiding obstruction. A flat mold 11 is movably arranged in the mold lifting bracket 10, and the flat mold 11 moves up and down linearly, such as Figure 1-3 shown.

[0051] Among them, a connecting groove 12 for inserting the aluminum bar 6 is opened at the outer position inside the flat die 11, a diverter groove 13 is opened at the middle position inside the flat die 11 and connected to the connecting groove 12, and the diverter groove 13 plays a diverting role. An extrusion groove 14 is opened at one end of the flat die 11 away from the connecting groove 12 (the shape of the extrusion groove 14 is determined according to the specific shape of the aluminum profile 54). Figure 4 shown.

[0052] In this embodiment, connecting arms 15 are symmetrically arranged at both ends of the flat mold 11, and vertical limiting grooves 52 for the movement of the connecting arms 15 are symmetrically arranged inside the mold lifting bracket 10. A screw nut sleeve 20 is installed through each set of connecting arms 15 (a nut with a spiral motion is installed inside the screw nut sleeve 20). Figure 4 shown.

[0053] In this embodiment, the screw nut sleeve 20 is for the long screw 21 to pass through, and the upper and lower ends of the long screw 21 are fixed by the first bearing seat 22 and the inner wall of the mold lifting bracket 10, playing a role of connection and fixing. Figure 4 shown.

[0054] The upper ends of the two sets of long screw rods 21 are sleeved with sprockets 23, and the two sets of sprockets 23 are connected by a synchronous chain 24 (the synchronous chain 24 is located at the upper position inside the mold lifting bracket 10). The upper end of one set of long screw rods 21 is connected to a screw motor 25 through a coupling, and the screw motor 25 is set through the upper end surface of the mold lifting bracket 10. Figure 2 and 4 shown.

[0055] Furthermore, a material receiving bed 8 is horizontally arranged at the right end of the mold lifting bracket 10 and located at the upper end of the support seat 7. A support leg is installed at the right end of the material receiving bed 8 to play a supporting role. A cutter 9 is riveted at the middle position of the right end surface of the mold lifting bracket 10 and located at the upper end of the material receiving bed 8. Figure 1-3 shown.

[0056] Specifically, the cutter 9 includes an annular mounting seat 90, a large gear 91, an annular positioning groove 92, a driving gear 93, a servo motor 94 and a motor housing 99. Figure 5-7 shown.

[0057] In this embodiment, a large gear 91 is rotatably arranged inside the annular mounting seat 90, and an annular positioning groove 92 is symmetrically provided on the inner and outer end surfaces of the large gear 91. A positioning block extending into the annular positioning groove 92 is arranged inside the annular mounting seat 90, and the positioning block and the annular positioning groove 92 move relative to each other. An annular opening is provided on the inner side surface of the annular mounting seat 90 for partially extending the large gear 91. A driving gear 93 is meshingly arranged on the upper end surface of the large gear 91, and the driving gear 93 is sleeved on the output shaft of a servo motor 94. The servo motor 94 is installed inside a motor housing 99, and the motor housing 99 is fixed to the upper end of the annular mounting seat 90.

[0058] Furthermore, the cutter 9 also includes an inner extension seat 95, a cutting motor 96, a connecting shaft 97 and an annular cutting blade 98. Figure 5-7 shown.

[0059] In this embodiment, an inner side of the large gear 91 is connected to an inner extension seat 95, and the inner extension seat 95 extends toward the inner center position of the annular mounting seat 90. A cutting motor 96 is installed horizontally through one side of the inner extension seat 95. The cutting motor 96 is connected to a connecting shaft 97 through a coupling. An annular cutting knife 98 is welded to the end of the connecting shaft 97. The annular cutting knife 98 is located inside the through opening 56 of the mold lifting bracket 10 (the movement range of the annular cutting knife 98 is within the through opening 56), and the annular cutting knife 98 acts on the aluminum profile 54 discharged from the extrusion groove 14.

[0060] When the aluminum profile 54 is cut, the aluminum profile 54 is located at an eccentric position of the annular mounting seat 90 (ensuring that the annular cutting knife 98 can completely cut the aluminum profile 54 ).

[0061] Furthermore, a discharge trough 30 is provided inside the support seat 7, and a punching cylinder 31 is horizontally installed in the discharge trough 30. Figure 3 and 8 shown.

[0062] The punching cylinder 31 has a punching rod 32 extending outward horizontally, and a punching head 33 is welded to the left end of the punching rod 32. Fig. 9 shown.

[0063] Among them, a discharge seat 34 is riveted at the middle position of the right end surface of the mold lifting bracket 10 and located in the discharge groove 30. A mold guide port 35 is opened inside the discharge seat 34. The cross-sectional shape of the mold guide port 35 is consistent with the extrusion groove 14. The mold guide port 35 is for the aluminum profile discharge mold 36 to pass through. The aluminum profile discharge mold 36 acts on the extrusion groove 14. The aluminum profile discharge mold 36 is made of high-strength alloy material, such as Figure 8-10 shown.

[0064] When the flat die 11 is unloaded, the unloading seat 34 and the flat die 11 are close to each other, and the die guide port 35 and the extrusion groove 14 correspond to each other.

[0065] Furthermore, baffles 55 are symmetrically arranged on the upper end surface of the receiving bed 8, and two sets of baffles 55 form a receiving channel 53 adapted to the aluminum profile 54, and the receiving channel 53 has a sufficient length, such as Fig.11 shown.

[0066] Furthermore, a plurality of groups of semicircular slots 50 are equidistantly provided on the side of the connecting arm 15, and each group of semicircular slots 50 is for a reinforcing rod 51 to pass through. The reinforcing rod 51 is movably arranged to penetrate the front and rear end surfaces of the mold lifting bracket 10. The reinforcing rod 51 acts on the connecting arm 15 to ensure the stability of the extrusion process of the flat mold 11 and play a role in reinforcing and shock absorbing. The reinforcing rod 51 can be flexibly pulled out, such as Figure 1 and 4 shown.

[0067] Furthermore, a waste trough for collecting waste is provided on the right end surface of the equipment body 1, and the waste trough and the unloading seat 34 are on the same horizontal plane.

[0068] When the present embodiment is in use, the preheated aluminum bar 6 is first transferred to the guide trough 5, and by starting the hydraulic cylinder 3, the extrusion rod 4 slowly extends horizontally to the right, pushing the aluminum bar 6 to move linearly, gradually entering the flat die 11, and slowly discharging the formed aluminum profile 54 from the extrusion trough 14, and the aluminum profile 54 enters the receiving channel 53. When cutting is required, the servo motor 94 is first started to drive the driving gear 93 to rotate, and the large gear 91 is decelerated by meshing, thereby driving the inner extension seat 95 to make a slow circular motion. When the annular cutting knife 98 on the inner extension seat 95 approaches the aluminum profile 54, the cutting motor 96 is turned on, and the connecting shaft 97 drives the annular cutting knife 98 to rotate at a high speed, causing the annular cutting knife 98 to make an arc motion around the aluminum profile 54 while cutting the aluminum profile 54 in depth (when the annular cutting knife 98 is at different points of the arc motion, the cutting depth of the aluminum profile 54 is different, and it is gradual), until the annular cutting knife 98 leaves the aluminum profile 54.

[0069] When extrusion and cutting are completed, the flat die 11 of the extrusion equipment is tightly filled with residual materials. At this time, the screw motor 25 is started first to drive a group of long screws 21 to rotate, and the other group of long screws 21 are caused to rotate synchronously through the transmission of the synchronous chain 24. The connecting arms 15 on the two groups of long screws 21 begin to move downward along the vertical limit groove 52 (the screw nut sleeve 20 in the connecting arm 15 and the spiral pattern on the long screw 21 interact with each other), causing the middle flat die 11 to move downward until the flat die 11 moves to the middle and lower part of the mold lifting bracket 10, and is close to and aligned with the unloading seat 34.

[0070] At this time, the punching cylinder 31 is started, and the punching rod 32 moves linearly outward, and the punching head 33 is used to hit the aluminum profile unloading die 36, causing the aluminum profile unloading die 36 to move linearly in the die guide port 35 of the unloading seat 34, and the end portion contacts the extrusion groove 14 of the flat die 11. The aluminum profile unloading die 36 exerts pressure on the residual material in the extrusion groove 14, causing the entire residual material in the flat die 11 to move to the left (the end portion of the aluminum profile unloading die 36 is inserted into the extrusion groove 14). After multiple collisions, the entire residual material in the flat die 11 is guided out from the direction of the connecting groove 12 and falls into the waste trough, thereby achieving the effect of removing the residual material. Embodiment 2

[0071] On the basis of the first embodiment, when cutting the aluminum profile 54, on the one hand, the aluminum profile 54 is long in structure, weak in structural strength, and lacks fixing measures, which easily causes the cutting position to shift and the incision to be oblique; on the other hand, before the aluminum profile 54 is transported to the annealing mechanism, it is easy to bump and deform during the transportation and transfer process, affecting the subsequent annealing cooling and straightening process. In order to solve the above technical problems, we have the following design, such as Figure 11-13 shown.

[0072] Specifically, the material receiving channel 53 and the extrusion groove 14 are at the same height. A wheel seat 40 is arranged above the material receiving channel 53. The two sides of the wheel seat 40 are respectively fixed to the baffle 55 through the connecting piece 41 to play the role of connection and fixing. A plurality of groups of positive pressure wheels 42 are equidistantly installed in the wheel seat 40, such as Fig.11 shown.

[0073] In this embodiment, the lower end of the positive pressure wheel 42 is in contact with the bottom of the aluminum profile 54 of the material receiving channel 53 (the wheel surface structure of the positive pressure wheel 42 is compatible with the bottom structure of the aluminum profile 54), the positive pressure wheel 42 is sleeved on the middle of the first wheel shaft 43, and both ends of the first wheel shaft 43 are fixed by the second bearing seat 44 and the inner wall of the wheel seat 40 (the first wheel shaft 43 is located above the material receiving channel 53). Fig.12 shown.

[0074] In this embodiment, the bottom of the two sets of second bearing seats 44 are both provided with arc-shaped connecting blocks 45, and the lower ends of the two sets of arc-shaped connecting blocks 45 are vertically welded with second wheel shafts 46. The lower end of the second wheel shaft 46 is sleeved with a connecting bearing 47, and the connecting bearing 47 is riveted to the center position of the side pressure wheel 48. The side pressure wheel 48 rotates around the second wheel shaft 46. The two sets of side pressure wheels 48 act on the inner side of the aluminum profile 54 respectively, as shown in FIG. Fig.13 shown.

[0075] Furthermore, inner wheel grooves are formed on the two inner side surfaces of the positive pressure wheel 42, and the side pressure wheels 48 are located in the inner wheel grooves to accommodate the side pressure wheels.

[0076] When this embodiment is in use, the aluminum profile 54 that enters the material receiving channel 53 is pressed against the bottom of the aluminum profile 54 by the lower end of the positive pressure wheel 42 in cooperation with the bottom of the material receiving channel 53 during movement. At the same time, the side wheel surfaces of the two sets of side pressure wheels 48 are pressed against the side edges of the aluminum profile 54 in cooperation with the side walls of the material receiving channel 53, thereby ensuring that the aluminum profile 54 is fully limited and straightened during movement, and avoiding deviation of the aluminum profile 54 during cutting.

[0077] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
