Description

Technical Field

[0001] The present invention relates to the field of laser cutting technology, and in particular to a laser cutting device and method for expanding machine processing. Background Art

[0002] The horizontal expanding machine consists of an upper template, a lower template, a die hole opened between the upper and lower templates, and a module fixed at one end of the die hole (a forming hole colinear with the die hole is opened on it, and the module is hard and the cost is relatively high. One is to prevent deformation when the pipe mouth is expanded, and the other is to reduce the cost). It is also necessary to set a stamping mechanism (such as a punch) on the end sides of the upper and lower templates. When in use, the upper template is opened upward relative to the lower template, and the pipe to be expanded is clamped in the die hole, so that one end of the pipe extends into the molding of the module, and the stamping mechanism moves relative to this end of the pipe and pushes into the pipe mouth, and the die head on the stamping mechanism is used to complete the expansion action at this end of the pipe mouth.

[0003] The upper template and the lower template are made by wire cutting, which ensures seamless connection between the two templates when they are closed. The conventional technical means is to use a laser cutting head to open a mold groove at the front end of the upper and lower molds on the laser cutting equipment according to the program, and then use a laser cutting head to process the forming holes on the module according to the program. When performing the above-mentioned laser cutting, in order to prevent the upper and lower templates and the module from moving, a positioning mechanism needs to be set to clamp them multiple times. After the mold holes are opened in the upper and lower templates by the drill bit on the drilling machine, they need to be transferred to the laser cutting equipment and re-clamped before the mold groove cutting is performed. The efficiency is low, so a device is needed to improve work efficiency. Summary of the invention

[0021] As a further preferred embodiment, a second stepped surface 23 is formed downwardly from the top surfaces of the two first clamping blocks 10 , and the top surfaces of the two second stepped surfaces 23 are of the same height.

[0022] As a further preferred embodiment, discharge plates 28 are provided on the opposite surfaces of the two clamping plates 4 , and the two discharge plates 28 are inclined toward the rear and downward direction, and the bottom surface of one discharge plate 28 overlaps the top surface of the other discharge plate 28 .

[0023] Working principle and technical effect: Processing with laser cutting machine Figure 1 When the belling machine is used, the laser cutting process is mainly applied to the upper template 29, the lower template 30 and the module 34, such as Figure 2 This is a laser cutting device provided by the present invention, specifically refers to the processing Figure 1 The fixture used for the above-mentioned parts in the belling machine shown in the figure is to fix the bottom plate 1 on the vertical drilling machine through the assembly hole 2, and then press the upper template 29 and the lower template 30 Figure 3 As shown, it stands upright between the two clamping plates 4, and then the crank arm 6 is deflected in the lower left direction, and the hinged end of the crank arm 6 drives the rotating rod 13, and then the rotating rod 13 drives the first gears 16 at the front and rear ends to rotate counterclockwise, and the two first gears 16 drive the two first racks 14 to move right, and the two first racks 14 push the two second clamping blocks 12 to move right, so that the right ends of the two second clamping blocks 12 respectively enter the back of the upper template 29 and the front of the lower template 30, and prevent the upper template 29 and the lower template 30 from moving forward and backward during the drilling operation (the upper template 29 and the lower template 30 are fixed). At this time, the upper template 29 and the lower template 30 face upward and face the drill bit, and the drill bit descends and drills a mold hole 32 in the upper template 29 and the lower template 30, and the waste falls onto the discharge plate 28 and is discharged out of the device by the discharge plate 28.

[0024] In addition, it is worth mentioning that when the above-mentioned parts in the above-mentioned expanding machine are cut on the laser cutting equipment by using the present device, the processing accuracy can be improved: after the upper template 29 and the lower template 30 have completed drilling the mold hole 32, the bottom plate 1 is quickly transferred to the laser cutting equipment through the assembly hole 2, and at this time, the upper template 29 and the lower template 30 will also be cut according to the laser cutting equipment. Figure 3 The shape shown is transferred to the laser cutting equipment along with the device, and the upper template 29 and the lower template 30 have been fixed in advance in the drilling process. The manipulator brings the laser cutting head 31 to the top of the mold hole 32. Under program control, the laser cutting head 31 opens a mold groove 33 downward from the top surface of the upper template 29 and the lower template 30. The round blocks dropped during laser cutting fall onto the discharge plate 28 and are discharged outward. Since the mold hole 32 corresponds to the bottom of the laser cutting head 31, according to the technical characteristics of CNC laser cutting machine programming, the laser cutting head 31 can use the center of the mold hole 32 as the starting point (X, Y, and Z coordinates are all 0) when aligning the tool. Then, the drawing trajectory of the mold groove 33 is input into the program through computer drawing software, and the mold groove 33 is processed with the center of the circle as the processing starting point, so that the mold groove 33 is processed more accurately, ensuring that the center of the mold groove 33 obtained after laser cutting is on the same axis as the center of the mold hole 32; press Figure 4 , Figure 5 , Figure 6 as well as Figure 7 As shown, the crank arm 6 is rotated to the upper right so that the free end of the crank arm 6 brings the clamping seat 8 to the top of the die hole 32. At this time, not only the center of the die groove 33 and the center of the die hole 32 are on the same axis, but also the center of the clamping cavity 9 and the center of the die hole 32 are on the same axis. Turn the bolt 24 so that the inner end of the bolt 24 is pressed against the locking port 25 at the outer end of the first clamping block 10 on the right side. Then, the module 34 is placed flat on the second step surface 23 at the inner ends of the left and right first clamping blocks 10. The locking bolt 24 causes the first clamping block 10 on the right end to move left, and the first clamping block 10 on the right end drives the second rack 27 on the right end to move left, and engages the second gear 26 to rotate counterclockwise, and the second gear 26 drives the second rack 27 on the left side to move right, and the second rack 27 on the left side drives the first clamping block 10 on the left side to move right, so that the module 34 is fixed. The rack and gear are linked to each other to ensure that the movement amplitude of the left and right first clamping blocks 10 is consistent, thereby ensuring that the center of the module 34 is also on the same axis as the center of the die hole 32. The robot moves up with the laser cutting head 31, changing the Z coordinate point, but the X and Y coordinate points still use the center of the circle as the processing starting point. Then, the drawing trajectory of the forming hole 35 is input into the program through the computer drawing software, and the forming hole 35 is processed on the module 34 with the center of the circle as the processing starting point, so that the processing accuracy of the forming hole 35 is more accurate, ensuring that the center of the forming hole 35 obtained after laser cutting is on the same axis as the center of the die hole 32, and the forming hole 35 is processed. Figure 1The expanding machine shown in the figure ensures that after the upper mold plate 29 and the lower mold plate 30 are opened, the round tube is placed in the mold hole 32, and at the same time, one end of the round tube can accurately extend out of the forming hole 35 of the module 34, and then the expanding is completed after the punching die head is aligned with the protruding end of the round tube and punched, thereby ensuring the quality of the expanding and avoiding material shortage or cracking at the tube mouth.

[0025] In summary, after the upper template 29 and the lower template 30 are positioned on the device, they are still fixed between the two clamping plates 4 when they are transferred to the laser cutting machine for laser cutting. The upper template 29 and the lower template 30 can be drilled and laser cut after one clamping, which is easy to operate. When the crank arm 6 rotates upward, in addition to bringing the center of the clamping seat 8 and the clamping cavity 9 to the coaxial line with the die hole 32 between the upper template 29 and the lower template 30, the hinged end of the crank arm 6 rotates clockwise with the rotating rod 13, and the front and rear ends of the rotating rod 13 rotate clockwise with the front and rear first gears 16, the two first gears 16 move the front and rear first racks 14 to the left, and the two first racks 14 move the front and rear second clamping blocks 12 to the left, the restrictions on the rear of the upper template 29 are released, and the restrictions on the front of the lower template 30 are released. The upper template 29 and the lower template 30 can be removed, and it is only necessary to position the module 34 in the clamping cavity 9 according to the above positioning method to complete the laser cutting of the forming hole 35. For horizontal reaming machines, the device provided by the present invention can not only quickly position the upper template 29 and the lower template 30, but also position the module 34. The positioning can be completed by rotating the crank arm 6 to the left or right. At the same time, the positioning component is also reflected on the crank arm 6 itself. In addition to facilitating operation and improving the laser cutting efficiency of this type of reaming machine, the processing accuracy is also improved under coaxial positioning.

[0026] The present invention also provides a method for using the laser cutting device for expanding machining as described above, comprising the following steps: Step S01, fix the bottom plate 1 on the workbench of the drilling machine through the assembly hole 2, and splice the upper template 29 and the lower template 30 front and back, and clamp them between the left and right clamping plates 4 in an upright manner; Step S02: On the drilling machine in step S01, a mold hole 32 is drilled from top to bottom on the upper mold plate 29 and the lower mold plate 30 by a drill bit; Step S03, transfer and fix the laser cutting device for expanding machine processing on the workbench of the laser cutting machine through the assembly hole 2 and the bottom plate 1, and cut the die groove 33 at the top of the upper template 29 and the lower template 30 by the laser cutting head 31; Step S04 , clamping the module 34 in the clamping cavity 9 , and using the laser cutting head 31 to cut a forming hole 35 on the module 34 that is coaxial with the mold hole 32 .
