Description

Technical Field

[0001] The utility model relates to the technical field of extrusion equipment, in particular to an extrusion system. Background Art

[0002] When an aluminum extruder is operating, the extrusion barrel fits tightly against the die end face, maintaining a locked state. The extrusion head, driven by a movable beam, enters the inner bore of the barrel, extruding the hot aluminum rod inside through the die's forming hole, forming aluminum profiles of various cross-sectional shapes. During the extrusion process, to prevent aluminum from flowing back through the gap between the extrusion head and barrel, the gap between the two is generally small, approximately 0.5mm per side. Therefore, during operation, the coaxiality of the extrusion head and barrel must be high, generally no greater than φ0.4. Alignment of the extrusion head and barrel is required before commissioning, when replacing the extrusion rod or barrel, and during regular maintenance. Furthermore, the operating temperature of the barrel is approximately 450°C, and thermal expansion and deformation are significant. Therefore, alignment should only be performed after the temperature has risen to the operating state and stabilized. 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 centering adjustment process, the operator needs to hold a feeler gauge to repeatedly check the clearances around the extrusion rod and the inlet and outlet ends of the extrusion barrel inner hole, 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 feeler gauge is difficult to guarantee, and there are large errors.

[0031] Example 1:

[0032] See Figure 1 and Figure 2This embodiment discloses an extrusion system. The extrusion system includes an extrusion body 1, a first positioning assembly 2, a second positioning assembly 3, a third positioning assembly 4, and a light source assembly 5. Preferably, the extrusion body 1 includes an extrusion head 11, an extrusion barrel 12, and a front beam 13 arranged in an array; the first positioning assembly 2 is assembled at the outlet end of the extrusion barrel 12; the second positioning assembly 3 is assembled at the inlet end of the extrusion barrel 12; the third positioning assembly 4 is arranged on the extrusion head 11; and the light source assembly 5 is assembled on the front beam 13 and can emit a reference light in the direction of the third positioning assembly 4. Preferably, the light source assembly 5 emits a reference light in the direction of the third positioning assembly 4, so that the deviation degree and direction of the extrusion head 11 and / or the extrusion barrel 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, which facilitates the operator to perform centering adjustment, replaces the traditional manual inspection method of using a feeler gauge, prevents the operator from being burned, and improves the accuracy of centering adjustment.

[0033] Optionally, the extrusion machine body 1 further includes a movable beam and an extrusion rod, wherein the movable beam is connected to the extrusion head 11 via the extrusion rod and is capable of pushing the extrusion head 11 into the inner hole of the extrusion barrel 12, thereby extruding the high-temperature aluminum rod in the extrusion barrel 12 from the forming hole of the mold to form aluminum profiles of various cross-sectional shapes. Optionally, the outlet end and inlet end of the extrusion barrel 12 are respectively the outlet end and inlet end of the inner hole of the extrusion barrel 12. Preferably, the outlet end of the extrusion barrel 12 is arranged near the end of the extrusion barrel 12 close to the front beam 13, and the inlet end of the extrusion barrel 12 is arranged near the end of the extrusion barrel 12 away from 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.

[0034] See Figure 1 、 Figure 2 、 Figure 3 and Figure 7In this embodiment, the light source assembly 5 includes a light source fixing plate 51 and a light source unit 52. 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 lens refracts the light emitted by the ordinary light source into a straight reference light. Optionally, the light source unit 52 is a laser light source, and the laser light source directly emits a straight reference light. Optionally, the light source fixing plate 51 can be of 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. Then, by observing the degree of deviation 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, the degree and direction of deviation of the extrusion head 11 and / or the extrusion cylinder 12 can be obtained.

[0035] See Figure 1 、 Figure 2 and Figure 3 In 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 the direction approaching the extrusion cylinder 12, so that the front beam 13 can be connected to the light source fixing plate 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 plate 51 is adapted to the shape of the positioning counterbore 111, so that the center of the light source fixing plate 51 that is matched 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 plate 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 then 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 from 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 remains coincident with the axis of the front beam 13.

[0036] See 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 cooperatively connected with the outlet end of the extrusion cylinder 12, 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 with each other, the degree of deviation between the outlet end of the extrusion cylinder 12 and the axis of the front beam 13 can be judged 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 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 driving the axis of the first light-transmitting hole 22 to be coaxial with the axis of the extrusion cylinder 12.

[0037] See Figure 1 、 Figure 2 、 Figure 5 and Figure 9In 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 and illuminate the second positioning assembly 3. However, the second positioning assembly 3 is assembled at the inlet end of the extrusion cylinder 12, so the reference light may be blocked by the second positioning assembly 3 on the side thereof close to the extrusion cylinder 12, thereby affecting the degree of deviation observed by the operator. Preferably, the second positioning assembly 3 includes a second positioning disk 31 that is cooperatively connected to the inlet end of the extrusion cylinder 12, and the second positioning disk 31 is provided with a light-transmitting hole 32. The circumference of the light-transmitting hole 32 extends away from the extrusion cylinder 12 to form a plurality of connection portions 33 spaced apart along the circumferential direction. The connection portion 33 is connected to an observation disk 34, and the observation disk 34 is provided with a second light-transmitting hole 35. 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 circumferentially adjacent connecting portions 33 forms an observation window, which facilitates the operator to clearly observe the degree of deviation 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 and illuminate the second positioning component 3. The reference light irradiated on the second positioning component 3 can pass through the light-transmitting hole 32 and illuminate the observation plate 34, so that the operator can observe the second light-transmitting hole 35 through the observation window between the connecting portions 33. The degree of deviation from the reference light is used to obtain the degree and direction of deviation of the inlet end of the extrusion cylinder 12, and then the position of the inlet 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.

[0038] See Figure 1 、 Figure 2 、 Figure 4 and Figure 5In this embodiment, the outlet end of the extrusion barrel 12 is provided with a first boss 121 that cooperates with the first positioning disk 21, and the inlet end of the extrusion barrel 12 is provided with a second boss 122 that cooperates with the second positioning disk 31. Optionally, the axes of the first boss 121 and the second boss 122 are both coaxial with the axis of the extrusion barrel 12. Optionally, by cooperating and connecting the first positioning disk 21 to the first boss 121, the axis of the first light-transmitting hole 22 is coaxial with the axis of the extrusion barrel 12, and by cooperating and connecting the second positioning disk 31 to the second boss 122, the axis of the second light-transmitting hole 35 is coaxial with the axis of the extrusion barrel 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 the 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 axis 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 realizing the observation of the degree and direction of deviation of the extrusion cylinder 12 without cleaning the aluminum chips in the extrusion cylinder 12, and effectively eliminating the error caused by the aluminum chips in the extrusion cylinder 12. Furthermore, the first positioning plate 21 is interference fit with the first boss 121, and the second positioning plate 31 is interference fit with the second boss 122, to prevent the high-temperature working environment from causing thermal expansion and deformation of the extrusion cylinder 12, thereby preventing the first positioning plate 21 and / or the second positioning plate 31 from shifting in position or even falling 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.

[0039] See Figure 7 、 Figure 8 and Figure 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 the plurality of 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 the removal and assembly of the light source fixing plate 51 on the front beam 13 is facilitated. It is understandable that, similarly, by distributing the 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 the removal and assembly of the first positioning plate 21 and / or the second positioning plate 31 on the extrusion cylinder 12 is facilitated. Furthermore, 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-fit ​​portions. The light source fixing plate 51 is interference-fitted with the front beam 13 via its snap-fit ​​portion, the first positioning plate 21 is interference-fitted with the outlet end of the extrusion barrel 12 via its snap-fit ​​portion, and the second positioning plate 31 is interference-fitted with the inlet end of the extrusion barrel 12 via its snap-fit ​​portion. Preferably, the slots 6 are distributed along the circumferential direction on the snap-fit ​​portions, thereby increasing the elastic deformation range of the snap-fit ​​portions, allowing the snap-fit ​​portions to deform in response to thermal expansion deformation of the front beam 13 or the extrusion barrel 12, driving the first positioning plate 21 and the second positioning plate 31 to be securely fixed to the extrusion barrel 12, and the light source fixing plate 51 to be securely fixed to the front beam 13, thereby accurately determining the degree and direction of deviation of the extrusion head 11 and / or the extrusion barrel 12. Furthermore, the ends of the snap-fit ​​portions may be provided with guiding bevels to facilitate installation.

[0040] See Figure 7 、 Figure 8 and Figure 9 In this embodiment, the light source fixing plate 51, the first positioning plate 21, and the second positioning plate 31 are each provided with a plurality of weight-reducing holes 7. Preferably, by providing the weight-reducing holes 7 on each of the light source fixing plate 51, the first positioning plate 21, and the second positioning plate 31, the weight of each of the light source fixing plate 51, the first positioning plate 21, and the second positioning plate 31 is reduced, making it easier for operators to assemble and disassemble the light source fixing plate 51, the first positioning plate 21, and the second positioning plate 31. Furthermore, by reducing weight, the installation and removal of any one or more of the light source fixing plate 51, the first positioning plate 21, and the second positioning plate 31 can be prevented from causing changes in the height of the front beam 13 and / or the extrusion cylinder 12, further improving the accuracy of centering adjustment.

[0041] See 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.

[0042] See 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 drive 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 movable beam. The operator adjusts the position of the movable beam through the third horizontal adjusting screw and / or the third height adjusting screw so that the movable 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.

[0046] 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. The light source assembly 5 is then assembled to the front beam 13, the first positioning assembly 2 is assembled to the outlet end of the extrusion cylinder 12, and the second positioning assembly 3 is assembled to 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 in the first positioning disk 21. Optionally, the first light-transmitting hole 22 is provided in 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 plate 31 which is cooperatively connected to the inlet end of the extrusion cylinder 12, and a light-through hole 32 is provided on the second positioning plate 31.

An observation plate 34 is connected to the connecting part 33, and the observation plate 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.

[0047] S2: Determine whether the reference light coincides with the first light-transmitting hole 22 on the first positioning component 2. If so, execute S4; if not, execute S3.

[0048] 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 from 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. 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. Step S3 is executed to adjust the position of the outlet end of the extrusion cylinder 12.

[0049] S3: Adjust the position of the extrusion cylinder 12 and return to execute S2;

[0050] Specifically, the outlet end of the extrusion cylinder 12 is connected to 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.

[0051] 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.

[0052] 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 on 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 degree of deviation between the second light-transmitting hole 35 and the reference light from the observation window between the connecting parts 33 to obtain the degree and direction of deviation 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 inlet end of the extrusion cylinder 12.

[0053] S5: Adjust the position of the extrusion cylinder 12 and return to execute S4;

[0054] Specifically, the inlet end of the extrusion cylinder 12 is connected to 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 coincides with the second light-transmitting hole 35.

[0055] S6: Determine whether the reference light coincides with the positioning hole 41 of the third positioning component 4. If so, execute S8; if not, execute S7;

[0056] 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 executed to further determine the coaxiality of the motion trajectory of the extrusion head 11 and 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 executed to adjust the position of the extrusion head 11.

[0057] S7: Adjust the position of the extrusion head 11 and return to execute S6;

[0058] 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 movable beam. The operator adjusts the position of the movable 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.

[0059] S8: drive the extrusion head 11 to move a certain distance toward the front beam 13, and again determine 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.

[0060] 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 judged. 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). 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 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 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 indicates that the position of the extrusion head 11 needs to be readjusted, and step S9 is executed.

[0061] 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.

[0062] S9: Adjust the position of the extrusion head 11 so that the positioning hole 41 coincides with the reference light, then drive the extrusion head 11 back to the initial position away from the front beam 13, and return to execute S6.

[0063] 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 so that the positioning hole 41 coincides 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.
