Description

Technical Field

[0001] This application relates to the field of industrial production equipment, and particularly to an assembly device for aluminum alloy extrusion. Background Art

[0002] Aluminum alloy extrusion is a processing technology that plastically forms aluminum alloy materials through a mold, and is widely used in the field of industrial manufacturing. Its basic principle is to place a heated and softened aluminum alloy blank (aluminum rod or ingot) in an extrusion cylinder, and force the metal to flow through a mold with a specific shape under high pressure to form profiles or pipes with the required cross-sectional profiles.

[0003] A core component in the extrusion process is the mold. The maintenance of the mold includes temperature control, cleaning, surface treatment, and trimming, etc. Among them, cleaning, surface treatment, and trimming involve disassembly, installation, and reinstallation.

[0004] Insufficient accuracy in the reinstallation process will lead to problems such as rapid wear of the mold, local wear of the mold, unstable production process, and decline in product quality. Currently, the reinstallation of the module mainly relies on manual operation.

[0005] However, with the increasing complexity of the mold and the refinement of its size, the implementation of the above methods becomes more and more difficult. The main reasons include that the deformation of the mold caused during use will reduce the accuracy of the positioning structure, and the decrease in the width of the mold gap and the change in the structure make it difficult for the feeler gauge to enter.

Specific embodiments

[0052] The following further elaborates on the technical solutions in the present application with reference to the accompanying drawings.

[0053] The assembly device for aluminum alloy extrusion disclosed in the present application is mainly used for mold position adjustment and mold assembly during the aluminum alloy extrusion production process. Please refer to Figure 1 , where mold position adjustment refers to adjusting the relative position of the first and second dividing dies, and mold assembly refers to assembling the first dividing die ( Figure 1 The die core located in the upper middle position in is connected to the surrounding structure through a flow dividing bridge (not shown)) and the second dividing die ( Figure 1 Located below in).

[0054] Through Figure 1 It can be seen that when the relative position of the first and second dividing dies in the horizontal direction is inaccurate, it will cause uneven thickness at the die exit. On the one hand, it will lead to uneven product thickness and potential internal and surface defects. On the other hand, it will also cause additional wear and reduced service life of the die core due to uneven stress.

[0055] This application discloses an assembly device for aluminum alloy extrusion. In some examples, the assembly device for aluminum alloy extrusion disclosed in this application includes an assembly base 1, a first adjustment module 2, a second adjustment module 3, a laser signal emission module 4, an annular flow guide 5, a position adjustment module 6, and a signal receiving disk 7.

[0056] Please refer to Figure 2 , there is a reference detection cavity 11 on the assembly base 1. Here, taking the posture of the assembly base 1 placed on the horizontal plane as a reference, the reference detection cavity 11 is located on the upper surface of the assembly base 1.

[0057] The first adjustment module 2, the second adjustment module 3, the laser signal emission module 4, and the annular flow guide 5 are all installed on the assembly base 1. The first adjustment module 2 is used to adjust the planar position of the first split die and drive the first split die to rotate on the horizontal plane. The second adjustment module 3 is used to adjust the planar position of the second split die and drive the second split die to move in the vertical direction. The laser signal emission module 4 is used to emit detection light rays to the detection surface of the second split die. The annular flow guide 5 is used to guide the detection light rays reflected on the detection surface of the second split die to the detection surface of the first split die, as Figure 3 shown.

[0058] A specific process will be described in combination:

[0059] First, place the first split die on the first adjustment module 2. The specific fixing method is as Figure 4 shown. The annular fixing ring is sleeved on the first split die and temporarily fixed with bolts around. Place the second split die on the second adjustment module 3, and the fixing method is the same.

[0060] Then start the preliminary position adjustment. Specifically, adjust the position of the first split die on the horizontal plane. After the adjustment is completed, adjust the height of the second split die according to the preliminarily measured optical path.

[0061] Then the laser signal emission module 4 emits detection light rays to the detection surface of the second split die. The detection light rays are reflected on the detection surface of the second split die and then reflected again on the annular flow guide 5, and then shoot towards the detection surface of the first split die.

[0062] The above process also requires the staff to make adjustments. Here, mainly adjust the height of the second split die and the reflection position provided by the annular flow guide 5 so that the detection light rays shoot towards the detection surface of the first split die.

[0063] Please refer to Figure 3 , Figure 5 and Figure 6, detect the light reflected at the detection surface of the first shunt die and then shoot towards the signal receiving disk 7. The function of the signal receiving disk 7 is to convert the received optical signal into an electrical signal, and the electrical signal can be displayed using position coordinates. Based on this, it can be judged whether the relative positions of the first shunt die and the second shunt die are appropriate.

[0064] The position adjustment module 6 is fixedly installed in the reference detection cavity 11, and the reference detection cavity 11 is located below the first adjustment module 2.

[0065] The signal receiving disk 7 is installed on the position adjustment module 6. The function of the position adjustment module 6 is to adjust the planar position of the signal receiving disk 7 and drive the signal receiving disk 7 to rotate on the horizontal plane.

[0066] The function of adjusting the planar position of the signal receiving disk 7 is to make the axis of the signal receiving disk 7 and the axis of the first shunt die or the second shunt die be on the same straight line. The function of driving the signal receiving disk 7 to rotate on the horizontal plane is to cooperate with the position adjustment of the laser signal emission module 4.

[0067] The purpose of the position adjustment of the laser signal emission module 4 is to emit detection light at different positions, aiming to make the finally obtained position adjustment amount more accurate through the multi-position detection method.

[0068] During the detection process described above, the first adjustment module 2 will drive the first shunt die to rotate. At this time, it is equivalent to the relative movement between a detection point on the second shunt die and a detection line (circular) on the first shunt die.

[0069] Please refer to Figure 6 and Figure 7 , if the relative positions of the first shunt die and the second shunt die on the horizontal plane are accurate, at this time, for the signal receiving disk 7, the detected line it outputs is a straight line or a curve that jumps within the allowable range; if the relative positions of the first shunt die and the second shunt die on the horizontal plane are inaccurate, at this time, for the signal receiving disk 7, the detected line it outputs is a curve that jumps outside the allowable range.

[0070] Furthermore, through the comparison of the two curves, the specific adjustment direction and adjustment amount can be determined. At the same time, after further adjustment and retesting, problems such as local deformation and inclination can also be found.

[0071] There is at least one set of symmetrically arranged signal receiving sensors 71 on the signal receiving disk 7. This means that the number of laser signal emission modules 4 is two, and the two laser signal emission modules 4 and a set of symmetrically arranged signal receiving sensors 71 need to work simultaneously in the initial stage.

[0072] Specifically, at this time, the positions of the detected light rays fed back by a set of symmetrically arranged signal receiving sensors 71 should be the same, which is the initial reference standard.

[0073] In some examples, refer to Figure 8 , the first adjustment module 2 includes a first linear module 21 and a turntable 22. The first linear module 21 is installed on the assembly base 1, and the turntable 22 is installed on the first linear module 21. The first linear module 21 provides lateral (X-axis) and longitudinal (Y-axis) movements on the horizontal plane, and the turntable 22 provides rotation (Z-axis) on the horizontal plane.

[0074] When the size is inappropriate, the first adjustment module 2 can also be fixedly installed on the reference detection cavity 11 through a column.

[0075] In some examples, refer to Figure 9 , the second adjustment module 3 includes a second linear module 31 and a lifter 32. The second linear module 31 is installed on the assembly base 1, and the lifter 32 is installed on the second linear module 31. The second linear module 31 provides lateral (X-axis) and longitudinal (Y-axis) movements on the horizontal plane, and the lifter 32 provides movement in the vertical direction (Z-axis).

[0076] When the weight of the mold is large, a light bar 33 can be added to prevent the mold from tilting, as shown in Figure 9 .

[0077] In some examples, refer to Figure 10 , the laser signal emission module 4 includes an angle adjustment turntable 41 and a laser signal emitter 42. The angle adjustment turntable 41 is installed on the assembly base 1, and the laser signal emitter 42 is installed on the angle adjustment turntable 41. The angle adjustment turntable 41 is used to adjust the incident angle of the laser signal emitter 42.

[0078] In some possible implementation manners, a lifter is further added to the laser signal emission module 4. The lifter is fixedly installed on the assembly base 1, and the angle adjustment turntable 41 is transferred to the lifter. The function of the lifter is to adjust the height of the laser signal emission module 4, aiming to adapt to molds of different specifications.

[0079] In some possible implementation manners, two sets of laser signal emission modules 4 share one lifter.

[0080] In some examples, refer to Figure 11, the annular flow guide member 5 includes lifting brackets 51 symmetrically arranged on the assembly base 1, linear expanders 52 fixedly installed on the lifting brackets 51, and flow guide half-rings 53 detachably fixed on the linear expanders 52. The lifting brackets 51 are responsible for providing height adjustment, and the linear expanders 52 are responsible for providing lateral adjustment. The two work together to achieve the optical path adjustment function described above.

[0081] Please refer to Figure 12 , the position adjustment module 6 includes a third linear module 61 and an electric turntable 62. The third linear module 61 is fixedly installed on the assembly base 1, and the electric turntable 62 is arranged on the third linear module 61. The structure and function of the position adjustment module 6 are the same as those of the first adjustment module 2, and will not be elaborated here.

[0082] In some examples, there are multiple groups of symmetrically arranged signal receiving sensors 71 on the signal receiving disk 7, and the spacing between each group of symmetrically arranged signal receiving sensors 71 is different. This is because when the specifications and related dimensions of the mold change, the relative positions between a group of signal receiving sensors 71 also need to change.

[0083] The function of adding multiple groups of signal receiving sensors 71 is that when the above changes occur, one of the groups of signal receiving sensors 71 can be directly called for use.

[0084] In some examples, please refer to

[0085] The detection surface of the signal receiving sensor 71 is circular in shape, aiming to receive the detection light as much as possible. It should be understood that when the detection light is reflected, the incident light and the reflected light should be in the same plane. However, when the detection light is reflected multiple times, the last reflected light and the initial incident light cannot be guaranteed to be in the same plane.

[0086] In some examples, please refer to Figure 13 , a display module 8 electrically connected to the signal receiving sensors 71 is added. The display module 8 is used to simultaneously display the receiving point positions on the detection surfaces of a group of symmetrically arranged signal receiving sensors 71, so that the staff can conveniently determine the adjustment direction and adjustment amount by observing the display module 8.

[0087] It should be understood that the signal receiving sensors 71 in this application use CMOS sensors, and the sensor data needs to be received through an FPGA or a microcontroller (such as STM32), processed, and then output to the display through a VGA or HDMI interface.

[0088] A feasible hardware link is as follows: signal receiving sensor 71 (DVP interface) → FPGA → HDMI encoding chip → display. Based on this, the display module 8 in this application can be composed of three parts: FPGA (microcontroller), HDMI encoding chip, and display.

[0089] In addition, for the actuators mentioned in the previous content, their power is all supplied by servo motors or stepper motors. The servo motors or stepper motors are connected to the corresponding control chips, and these control chips are connected to a microcontroller (such as STM32) for control. The relevant action adjustments are realized by control buttons, and the control buttons are connected to the communication pins of the microcontroller through the corresponding communication circuits.

[0090] The embodiments of this specific implementation manner are all preferred embodiments of this application, and do not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
