Description

Technical Field

[0001] The present invention relates to the technical field of extrusion equipment, and in particular to an extrusion system and a centering adjustment method. Background Art

[0002] When the aluminum extruder is working, the extrusion barrel and the die end face are tightly fitted and locked, and the extrusion head enters the inner hole of the extrusion barrel under the push of the moving beam, and extrude the high-temperature aluminum rod in the extrusion barrel from the forming hole of the die to form aluminum profiles of various cross-sectional shapes. During the extrusion process, in order to prevent the aluminum from flowing back from the gap between the extrusion head and the extrusion barrel, the gap between the two is generally small, and the single-side gap is about 0.5mm. Therefore, during the operation of the equipment, the coaxiality requirements of the extrusion head and the extrusion barrel are relatively high, generally not greater than φ0.4. Before equipment commissioning, replacement of the extrusion rod or extrusion barrel, regular maintenance, etc., it is necessary to adjust the extrusion head and the extrusion barrel. In addition, the working temperature of the extrusion barrel is about 450 degrees, and the thermal expansion deformation cannot be ignored. Therefore, the centering adjustment can only be performed after the temperature rises to the working state and stabilizes. In the traditional process, it is generally necessary to clean the aluminum chips on the inner wall of the extrusion barrel in advance, then remove the extrusion head, and adjust the extrusion barrel with the extrusion rod as the reference. In the process of centering adjustment, the operator needs to hold a feeler gauge to repeatedly check the clearance around the extrusion rod and the inlet and outlet ends of the inner hole of the extrusion barrel, so as to obtain the degree and direction of deviation between the extrusion rod and the inner hole of the extrusion barrel, and then adjust the position of the extrusion barrel based on this. As a result, there are many deficiencies in the existing centering adjustment process: first, the operator is easily burned when measuring and reading with a feeler gauge; second, the aluminum chips on the inner wall of the extrusion barrel are difficult to completely remove, which has a significant impact on the measurement results of the feeler gauge; third, the measurement accuracy of manual use of a feeler gauge is difficult to guarantee, and there is a large error.

Optionally, the outlet end and the inlet end of the extrusion cylinder 12 are respectively the outlet end and the inlet end of the inner hole of the extrusion cylinder 12. Preferably, the outlet end of the extrusion cylinder 12 is arranged at one end of the extrusion cylinder 12 close to the front beam 13, and the inlet end of the extrusion cylinder 12 is arranged at one end of the extrusion cylinder 12 close to the front beam 13, and the inlet end of the extrusion cylinder 12 is arranged at one end of the extrusion cylinder 12 close to the front beam 13. Optionally, the degree of deviation and direction of the extrusion head 11 and / or the extrusion cylinder 12 can be directly obtained by judging the degree of deviation between the reference light and one or more of the first positioning component 2, the second positioning component 3 and the third positioning component 4; optionally, the first positioning component 2, the second positioning component 3 and the third positioning component 4 can be provided with corresponding reference points or specific structures / areas such as through holes, and the degree of deviation and direction of the extrusion head 11 and / or the extrusion cylinder 12 can be obtained by judging the degree of deviation between the reference light and the specific structure / area.

[0043] See also Figure 1 , Figure 2 , Figure 3 and Figure 7 In this embodiment, the light source assembly 5 includes a light source fixing plate 51 and a light source unit 52, and the light source unit 52 is assembled at the center of the outlet end of the front beam 13 through the light source fixing plate 51. Optionally, the light source unit 52 can be formed by combining an ordinary light source and a lens, and the light emitted by the ordinary light source is refracted into a straight reference light by the lens. Optionally, the light source unit 52 is a laser light source, and the straight reference light is directly emitted by the laser light source; Optionally, the light source fixing plate 51 can be any shape, such as a regular polygon, a rhombus, a circle, etc. Preferably, by assembling the light source unit 52 at the center of the outlet end of the front beam 13 through the light source fixing plate 51, the reference light emitted by the light source unit 52 in the direction of the third positioning assembly 4 is coaxial with the axis of the front beam 13, and then the deviation degree and direction of the extrusion head 11 and / or the extrusion cylinder 12 can be obtained by observing the deviation degree between one or more of the first positioning assembly 2, the second positioning assembly 3 and the third positioning assembly 4 and the reference light.

[0044] See also Figure 1 , Figure 2 and Figure 3In this embodiment, a positioning countersunk hole 111 is formed at the outlet end of the front beam 13 , and the light source fixing plate 51 is connected to the positioning countersunk hole 111 . Optionally, the inner diameter of the positioning counterbore 111 is arranged to decrease in a direction approaching the extrusion cylinder 12, so that the front beam 13 can be matched and connected with the light source fixing disk 51 of different specifications through the positioning counterbore 111. Optionally, the axis of the positioning counterbore 111 is coaxial with the axis of the front beam 13, and the shape of the light source fixing disk 51 is adapted to the shape of the positioning counterbore 111, so that the center of the light source fixing disk 51 matched and connected with the positioning counterbore 111 is coaxial with the axis of the front beam 13, thereby driving the light source unit 52 assembled at the center of the light source fixing disk 51 to be located on the axis of the front beam 13, so that the reference light emitted by the light source unit 52 is coaxial with the axis of the front beam 13, and thereby the deviation degree and direction of the extrusion head 11 and / or the extrusion cylinder 12 can be obtained by observing the degree of deviation between the first positioning component 2, the second positioning component 3 and the third positioning component 4 and the reference light. Furthermore, the light source fixing plate 51 is interference fit with the positioning countersunk hole 111 to prevent the high-temperature working environment from causing thermal expansion and deformation of the front beam 13, which may cause the assembly position of the light source fixing plate 51 to shift or even fall off the front beam 13, so that the light source fixing plate 51 can be continuously and reliably fixed in the positioning countersunk hole 111, ensuring that the reference light beam remains coincident with the axis of the front beam 13.

[0045] See also Figure 1 , Figure 2 , Figure 4 and Figure 8 In this embodiment, the first positioning assembly 2 includes a first positioning disk 21 and a first light-transmitting hole 22 provided in the first positioning disk 21. The first positioning disk 21 is connected with the outlet end of the extrusion cylinder 12 in cooperation, and the axis of the first light-transmitting hole 22 is coaxial with the axis of the extrusion cylinder 12. Preferably, by observing whether the reference light and the first light-transmitting hole 22 coincide, the degree of deviation between the outlet end of the extrusion cylinder 12 and the axis of the front beam 13 can be judged, so as to obtain the degree and direction of deviation of the outlet end of the extrusion cylinder 12, and this can be used as an adjustment basis to adjust the position of the outlet end of the extrusion cylinder 12 to make it coincide with the first light-transmitting hole 22 by observing the reference light. Optionally, the first light-transmitting hole 22 is provided at the center of the first positioning disk 21, and the shape of the first positioning disk 21 is adapted to the outlet end of the extrusion cylinder 12, so that the axis of the first positioning disk 21 is coaxial with the axis of the extrusion cylinder 12, thereby making the axis of the first light-transmitting hole 22 coaxial with the axis of the extrusion cylinder 12.

[0046] See also Figure 1, Figure 2 , Figure 5 and Fig. 9 In this embodiment, when the reference light coincides with the first light-transmitting hole 22, the reference light can pass through the first light-transmitting hole 22 to illuminate the second positioning component 3, but the second positioning component 3 is assembled at the entrance end of the extrusion cylinder 12, so the reference light may be blocked by the second positioning component 3 on the side close to the extrusion cylinder 12, thereby affecting the degree of deviation observed by the operator. Preferably, the second positioning component 3 includes a second positioning plate 31 that is cooperatively connected to the entrance end of the extrusion cylinder 12, and a light-transmitting hole 32 is provided on the second positioning plate 31. The circumference of the light-transmitting hole 32 extends in a direction away from the extrusion cylinder 12 to form a plurality of connection parts 33 that are spaced apart along the circumferential direction, and an observation plate 34 is connected to the connection part 33. The observation plate 34 is provided with a second light-transmitting hole 35, and the axis of the second light-transmitting hole 35 is coaxial with the axis of the first light-transmitting hole 22. The gap between two adjacent connecting parts 33 along the circumferential direction forms an observation window, which is convenient for the operator to clearly observe the deviation degree between the second light-transmitting hole 35 on the observation plate 34 and the reference light. When the reference light coincides with the first light-transmitting hole 22, the reference light can pass through the first light-transmitting hole 22 to irradiate the second positioning component 3, and the reference light irradiated to the second positioning component 3 can pass through the light-transmitting hole 32 to irradiate the observation plate 34, so that the operator can observe the second light-transmitting hole 35 from the observation window between the connecting parts 33. The degree of deviation from the reference light is determined to obtain the degree and direction of deviation of the entrance end of the extrusion cylinder 12, and then the position of the entrance end of the extrusion cylinder 12 is centered and adjusted to drive the second light-transmitting hole 35 to coincide with the reference light. Specifically, since the axis of the second light-transmitting hole 35 is coaxial with the axis of the first light-transmitting hole 22, when the reference light that coincides with the first light-transmitting hole 22 coincides with the second light-transmitting hole 35 again, that is, the axis of the extrusion cylinder 12 coincides with the reference light, the axis of the extrusion cylinder 12 coincides with the axis of the front beam 13 and is coaxial.

[0047] See also Figure 1 , Figure 2 , Figure 4 and Figure 5In this embodiment, the outlet end of the extrusion cylinder 12 is provided with a first boss 121 that is matched and connected with the first positioning disk 21, and the inlet end of the extrusion cylinder 12 is provided with a second boss 122 that is matched and connected with the second positioning disk 31. Optionally, the axis of the first boss 121 and the axis of the second boss 122 are both coaxial with the axis of the extrusion cylinder 12. Optionally, the first positioning disk 21 is matched and connected to the first boss 121, so that the axis of the first light-transmitting hole 22 is coaxial with the axis of the extrusion cylinder 12, and the second positioning disk 31 is matched and connected to the second boss 122, so that the axis of the second light-transmitting hole 35 is coaxial with the axis of the extrusion cylinder 12. Preferably, the outlet end of the extrusion cylinder 12 protrudes toward the front beam 13 to form the first boss 121, and the inlet end of the extrusion cylinder 12 protrudes toward the extrusion head 11 to form the second boss 122, and the first positioning plate 21 cooperates to connect the first boss 121 and the second positioning plate 31 cooperates to connect the second boss 122, thereby preventing aluminum chips remaining in the extrusion cylinder 12 from affecting the assembly position of the first positioning plate 21 and / or the second positioning plate 31, thereby ensuring that the axes of the first light-transmitting hole 22 and the second light-transmitting hole 35 are coaxial with the axis of the extrusion cylinder 12, thereby achieving the ability to observe the degree and direction of deviation of the extrusion cylinder 12 without cleaning the aluminum chips in the extrusion cylinder 12, thereby effectively eliminating the error caused by the aluminum chips in the extrusion cylinder 12. Furthermore, the first positioning plate 21 has an interference fit with the first boss 121, and the second positioning plate 31 has an interference fit with the second boss 122, so as to prevent the high-temperature working environment from causing the extrusion cylinder 12 to expand and deform due to heat, thereby causing the first positioning plate 21 and / or the second positioning plate 31 to shift in position or even fall off the extrusion cylinder 12, so that the first positioning plate 21 and / or the second positioning plate 31 can be reliably fixed on the extrusion cylinder 12, ensuring that the axes of the first light-transmitting hole 22 and the second light-transmitting hole 35 remain coincident with the axis of the extrusion cylinder 12.

[0048] See also Figure 7 , Figure 8 and Fig. 9In this embodiment, the peripheral edges of the light source fixing plate 51, the first positioning plate 21 and the second positioning plate 31 are all provided with a plurality of grooves 6 distributed along the circumferential direction. Preferably, by distributing a plurality of the grooves 6 along the circumferential direction on the peripheral edges of the light source fixing plate 51, the elastic deformation range of the light source fixing plate 51 is increased, and it is convenient to disassemble and assemble the light source fixing plate 51 on the front beam 13. It can be understood that, similarly, by distributing a plurality of grooves 6 along the circumferential direction on the peripheral edges of the first positioning plate 21 and the second positioning plate 31, the elastic deformation range of the first positioning plate 21 and the second positioning plate 31 is increased, and it is convenient to disassemble and assemble the first positioning plate 21 and / or the second positioning plate 31 on the extrusion cylinder 12. Further, the peripheral edges of the light source fixing plate 51, the first positioning plate 21 and the second positioning plate 31 are all provided with snap parts, the light source fixing plate 51 is interference fit with the front beam 13 through its snap parts, the first positioning plate 21 is interference fit with the outlet end of the extrusion cylinder 12 through its snap parts, and the second positioning plate 31 is interference fit with the inlet end of the extrusion cylinder 12 through its snap parts. Preferably, the grooves 6 are distributed on the snap parts along the circumferential direction, thereby increasing the elastic deformation range of the snap parts, so that the snap parts can deform along with the thermal expansion deformation of the front beam 13 or the extrusion cylinder 12, driving the first positioning plate 21 and the second positioning plate 31 to be reliably fixed on the extrusion cylinder 12, and the light source fixing plate 51 can be reliably fixed on the front beam 13, thereby accurately judging the degree and direction of deviation of the extrusion head 11 and / or the extrusion cylinder 12. Further, the end of the snap part can also be provided with a guiding bevel for easy installation.

[0049] See also Figure 7 , Figure 8 and Fig. 9 In this embodiment, the light source fixing plate 51, the first positioning plate 21 and the second positioning plate 31 are all provided with a plurality of weight-reducing holes 7. Preferably, by providing the light source fixing plate 51, the first positioning plate 21 and the second positioning plate 31 with the weight-reducing holes 7, the weight of each of the light source fixing plate 51, the first positioning plate 21 and the second positioning plate 31 can be reduced, so that the operator can conveniently perform the assembly and disassembly operations on the light source fixing plate 51, the first positioning plate 21 and the second positioning plate 31. Furthermore, by reducing the weight, it is possible to prevent the loading and unloading of any one or more of the light source fixing plate 51, the first positioning plate 21 and the second positioning plate 31 from causing the height of the front beam 13 and / or the extrusion cylinder 12 to change, thereby further improving the accuracy of the centering adjustment.

[0050] See also Figure 1 , Figure 2 and Figure 6 In this embodiment, the third positioning component 4 includes a positioning hole 41 opened in the extrusion head 11 , and the axis of the positioning hole 41 is coaxial with the axis of the extrusion head 11 . Preferably, the degree of deviation and direction of the extrusion head 11 is obtained by observing the degree of deviation between the positioning hole 41 and the reference light. Optionally, before observing the degree of deviation between the positioning hole 41 and the reference light, the extrusion cylinder 12 needs to be centered so that the reference light passing through the first light-transmitting hole 22 and the second light-transmitting hole 35 is irradiated to the extrusion head 11, and then the degree of deviation between the positioning hole 41 and the reference light is observed. Alternatively, after the extrusion cylinder 12 is centered, the first positioning component 2 and the second positioning component 3 are removed from the extrusion cylinder 12 so that the extrusion head 11 can move, and then the degree of deviation between the positioning hole 41 on the extrusion head 11 that has moved a certain distance and the reference light is observed, so as to judge the degree of deviation between the motion trajectory of the extrusion head 11 and the reference laser line. After the extrusion head 11 moves a certain distance, the extrusion head 11 can maintain a certain distance from the extrusion cylinder 12, or the extrusion head 11 extends into the extrusion cylinder 12, or the extrusion head 11 extends from the outlet end of the extrusion cylinder 12. Furthermore, the extrusion head 11 is made of carbon steel material, which makes the color of the extrusion head 11 different from that of aluminum. Therefore, even if the positioning hole 41 of the used extrusion head 11 is filled with aluminum, the position of the positioning hole 41 can be identified by the difference in color, thereby realizing the observation of the degree of deviation between the positioning hole 41 and the reference light without cleaning the extrusion head 11.

[0051] See also Figure 1 and Figure 2In this embodiment, it also includes a first adjusting member 14, a second adjusting member 15 and a third adjusting member 16, wherein the first adjusting member 14 is connected to the outlet end of the extrusion cylinder 12, and is used to adjust the position of the outlet end of the extrusion cylinder 12; the second adjusting member 15 is connected to the inlet end of the extrusion cylinder 12, and is used to adjust the position of the inlet end of the extrusion cylinder 12; the third adjusting member 16 is connected to the extrusion head 11, and is used to adjust the position of the extrusion head 11. Optionally, the first adjusting member 14, the second adjusting member 15 and the third adjusting member 16 can be driving motors, cylinders, screws and other devices, which can adjust the position of the extrusion head 11 and / or the extrusion cylinder 12; preferably, the first adjusting member 14 includes a first horizontal adjustment screw for adjusting the horizontal position of the outlet end of the extrusion cylinder 12 and a first height adjustment screw for adjusting the height position of the outlet end of the extrusion cylinder 12. The operator can adjust the position of the outlet end of the extrusion cylinder 12 through the first horizontal adjustment screw and / or the first height adjustment screw according to the degree of deviation between the first light-transmitting hole 22 and the reference light, so that the first light-transmitting hole 22 coincides with the reference light. Preferably, the second adjusting member 15 includes a second horizontal adjusting screw for adjusting the horizontal position of the inlet end of the extrusion cylinder 12 and a second height adjusting screw for adjusting the height position of the inlet end of the extrusion cylinder 12. The operator can adjust the position of the inlet end of the extrusion cylinder 12 through the second horizontal adjusting screw and / or the second height adjusting screw according to the degree of deviation between the second light-transmitting hole 35 and the reference light, so that the second light-transmitting hole 35 coincides with the reference light. Preferably, the third adjusting member 16 includes a third horizontal adjusting screw and a third height adjusting screw. The operator can adjust the position of the extrusion head 11 through the third horizontal adjusting screw and the third height adjusting screw according to the degree of deviation between the positioning hole 41 and the reference light. Furthermore, the third horizontal adjusting screw and the third height adjusting screw are both connected to the moving beam. The operator adjusts the position of the moving beam through the third horizontal adjusting screw and / or the third height adjusting screw so that the moving beam drives the extrusion head 11 through the extrusion rod, thereby adjusting the position of the extrusion head 11 so that the positioning hole 41 coincides with the reference light.

[0055] Specifically, the mold is removed, and a certain distance is maintained between the extrusion head 11, the extrusion cylinder 12 and the front beam 13 for easy operation and observation, and then the light source assembly 5 is assembled on the front beam 13, the first positioning assembly 2 is assembled on the outlet end of the extrusion cylinder 12, and the second positioning assembly 3 is assembled on the inlet end of the extrusion cylinder 12. Preferably, the first positioning assembly 2 includes a first positioning disk 21 and a first light-transmitting hole 22 provided on the first positioning disk 21. Optionally, the first light-transmitting hole 22 is provided at the center of the first positioning disk 21. The shape of the first positioning disk 21 is adapted to the outlet end of the extrusion cylinder 12, so that the axis of the first positioning disk 21 is coaxial with the axis of the extrusion cylinder 12, thereby driving the axis of the first light-transmitting hole 22 to be coaxial with the axis of the extrusion cylinder 12. Preferably, the second positioning assembly 3 includes a second positioning disk 31 which is cooperatively connected to the inlet end of the extrusion cylinder 12, and a light-through hole 32 is formed on the second positioning disk 31. The circumferential side of the light-through hole 32 extends away from the extrusion cylinder 12 to form a plurality of connecting parts 33 spaced apart along the circumferential direction. An observation disk 34 is connected to the connecting part 33, and the observation disk 34 is provided with a second light-through hole 35. The axis of the second light-through hole 35 is coaxial with the axis of the first light-through hole 22. Preferably, the light source assembly 5 includes a light source fixing plate 51 and a light source unit 52, wherein the light source unit 52 is assembled at the center of the outlet end of the front beam 13 through the light source fixing plate 51, so that the reference light emitted by the light source assembly 5 in the direction of the third positioning assembly 4 is coaxial with the axis of the front beam 13; optionally, the light source unit 52 is a laser light source, which directly emits a straight reference light; when the light source assembly 5, the first positioning assembly 2 and the second positioning assembly 3 are all assembled, the light source unit 52 can be turned on to emit a reference light in the direction of the third positioning assembly 4.

[0056] S2: Determine whether the reference light beam coincides with the first light-transmitting hole 22 on the first positioning component 2. If so, execute S4; if not, execute S3;

[0057] Specifically, by observing whether the reference light coincides with the first light-transmitting hole 22, the degree of deviation of the center of the outlet end of the extrusion cylinder 12 and the axis of the front beam 13 is determined to obtain the degree and direction of deviation of the outlet end of the extrusion cylinder 12. If the reference light coincides with the first light-transmitting hole 22, it means that the axis of the first light-transmitting hole 22 is coaxial with the axis of the front beam 13, and step S4 is executed to further determine whether the reference light coincides with the second light-transmitting hole 35 on the second positioning component 3. If the reference light does not coincide with the first light-transmitting hole 22, it means that the first light-transmitting hole 22 deviates from the axis of the front beam 13, and step S3 is executed to adjust the position of the outlet end of the extrusion cylinder 12.

[0058] S3: Adjust the position of the extrusion cylinder 12, and return to execute S2;

[0059] Specifically, the outlet end of the extrusion cylinder 12 is connected with the first adjusting member 14, and the first adjusting member 14 can adjust the position of the outlet end of the extrusion cylinder 12. Optionally, the first adjusting member 14 can be a driving motor, a cylinder, a screw and other devices. Optionally, the first adjusting member 14 includes a first horizontal adjustment screw for adjusting the horizontal position of the outlet end of the extrusion cylinder 12 and a first height adjustment screw for adjusting the height position of the outlet end of the extrusion cylinder 12. The operator can adjust the position of the outlet end of the extrusion cylinder 12 through the first horizontal adjustment screw and / or the first height adjustment screw according to the degree of deviation between the first light-transmitting hole 22 and the reference light, and then return to step S2 to re-observe whether the reference light coincides with the first light-transmitting hole 22.

[0060] S4: Determine whether the reference light coincides with the second light-transmitting hole 35 on the second positioning component 3. If so, remove the first positioning component 2 and the second positioning component 3 from the extrusion cylinder 12 and execute S6. If not, execute S5.

[0061] Specifically, when the reference light coincides with the first light-transmitting hole 22, the reference light can pass through the first light-transmitting hole 22 to illuminate the second positioning component 3, and the reference light irradiated to the second positioning component 3 can pass through the light-transmitting hole 32 to illuminate the observation disk 34, so that the operator can observe the deviation degree between the second light-transmitting hole 35 and the reference light from the observation window between the connecting parts 33, so as to obtain the deviation degree and direction of the outlet end of the extrusion cylinder 12. If the reference light coincides with the second light-transmitting hole 35, it means that the outlet end and the inlet end of the extrusion cylinder 12 are aligned. The axes of the ends are coaxial with the axis of the front beam 13, that is, the axis of the extrusion cylinder 12 is coaxial with the axis of the front beam 13, and the centering adjustment of the extrusion cylinder 12 is completed. At this time, the first positioning component 2 and the second positioning component 3 can be removed from the extrusion cylinder 12, and step S6 is further executed to determine whether the reference light coincides with the positioning hole 41 of the third positioning component 4. If the reference light does not coincide with the second light-transmitting hole 35, it means that the second light-transmitting hole 35 deviates from the axis of the front beam 13, and step S5 is executed to adjust the position of the entrance end of the extrusion cylinder 12.

[0062] S5: Adjust the position of the extrusion cylinder 12, and return to execute S4;

[0063] Specifically, the inlet end of the extrusion cylinder 12 is connected with the second adjusting member 15, and the second adjusting member 15 can adjust the position of the inlet end of the extrusion cylinder 12. Optionally, the second adjusting member 15 can be a driving motor, a cylinder, a screw and other devices. Optionally, the second adjusting member 15 includes a second horizontal adjustment screw for adjusting the horizontal position of the inlet end of the extrusion cylinder 12 and a second height adjustment screw for adjusting the height position of the inlet end of the extrusion cylinder 12. The operator can adjust the position of the inlet end of the extrusion cylinder 12 through the second horizontal adjustment screw and / or the second height adjustment screw according to the degree of deviation between the second light-transmitting hole 35 and the reference light, and then return to step S4 to re-observe whether the reference light and the second light-transmitting hole 35 coincide with each other.

[0064] S6: Determine whether the reference light beam coincides with the positioning hole 41 of the third positioning component 4, if yes, execute S8, if no, execute S7;

[0065] Specifically, the degree of deviation and direction of the extrusion head 11 are obtained by observing the degree of deviation between the positioning hole 41 and the reference light. If the reference light coincides with the positioning hole 41, it indicates that the axis of the positioning hole 41 is coaxial with the axis of the front beam 13. Step S8 is performed to further determine the coaxiality of the motion trajectory of the extrusion head 11 with the axis of the front beam 13. If the reference light does not coincide with the positioning hole 41, it indicates that the positioning hole 41 deviates from the axis of the front beam 13. Step S7 is performed to adjust the position of the extrusion head 11.

[0066] S7: Adjust the position of the extrusion head 11, and return to execute S6;

[0067] Specifically, the extrusion head 11 is connected to the third adjusting member 16, and the third adjusting member 16 can adjust the position of the extrusion head 11. Optionally, the third adjusting member 16 can be a driving motor, a cylinder, a screw and other devices. Optionally, the third adjusting member 16 includes a third horizontal adjustment screw and a third height adjustment screw. The operator can adjust the position of the extrusion head 11 through the third horizontal adjustment screw and the third height adjustment screw according to the degree of deviation between the positioning hole 41 and the reference light. Furthermore, the third horizontal adjustment screw and the third height adjustment screw are both connected to the moving beam. The operator adjusts the position of the moving beam through the third horizontal adjustment screw and / or the third height adjustment screw, and then returns to step S6 to re-observe whether the reference light coincides with the positioning hole 41, and repeats this cycle until the positioning hole 41 coincides with the reference light.

[0068] S8: drive the extrusion head 11 to move a certain distance toward the front beam 13, and determine again whether the reference light coincides with the positioning hole 41 of the third positioning component 4. If so, end the program; if not, execute S9.

[0069] When the reference light coincides with the positioning hole 41 of the third positioning component 4 (the current position is defined as the initial position), the coaxiality of the motion trajectory of the extrusion head 11 and the axis of the front beam 13 is further determined. Specifically, the extrusion head 11 is driven to move a certain distance toward the front beam 13 (at this time, the extrusion head 11 can maintain a certain distance from the extrusion cylinder 12, or the extrusion head 11 extends into the extrusion cylinder 12, or the extrusion head 11 extends from the outlet end of the extrusion cylinder 12), and the degree of deviation between the positioning hole 41 and the reference light is observed again. If the positioning hole 41 of the third positioning component 4 and the reference light still coincide with each other after moving a certain distance, it indicates that the motion trajectory of the extrusion head 11 is coaxial with the axis of the front beam 13, and the centering adjustment of the extrusion head 11 is completed. If the positioning hole 41 of the third positioning component 4 and the reference light do not coincide with each other after moving a certain distance, it indicates that the motion trajectory of the extrusion head 11 deviates from the axis of the front beam 13, which means that the position of the extrusion head 11 needs to be readjusted, and step S9 is executed.

[0070] Furthermore, during the movement of the extrusion head 11 toward the front beam 13, the degree of deviation between the positioning hole 41 and the reference light can be directly observed to determine whether the movement trajectory of the extrusion head 11 is coaxial with the axis of the front beam 13, without measuring the distance between the extrusion head 11 and the extrusion cylinder 12, so that the extrusion head 11 and the extrusion cylinder 12 are relatively independent during the centering adjustment process, preventing the extrusion head 11 and the extrusion cylinder 12 from interfering with each other, and optimizing the centering adjustment process.

[0071] S9: adjusting the position of the extrusion head 11 so that the positioning hole 41 coincides with the reference light, and then driving the extrusion head 11 to return to the initial position away from the front beam 13, and returning to execute S6.

[0072] Specifically, when the positioning hole 41 of the third positioning component 4 does not coincide with the reference light after moving a certain distance, the position of the extrusion head 11 is adjusted at the current position to make the positioning hole 41 coincide with the reference light, and then the extrusion head 11 is driven back to the initial position away from the front beam 13, and S6 is executed to re-judge whether the positioning hole 41 at the initial position coincides with the reference light, and this cycle is repeated until the motion trajectory of the extrusion head 11 is coaxial with the axis of the front beam 13.
