Description

Technical Field

[0001] The present invention relates to the technical field of metal welding equipment, and in particular to automated laser welding equipment and a process based on efficient processing of metal plates. Background Art

[0002] Laser cutting technology, with its advantages of high precision, high efficiency and non-contact processing, has become one of the core processes for metal sheet processing in modern manufacturing, and is widely used in aerospace, automobile manufacturing, shipbuilding industry and other fields.

[0003] Currently, mainstream laser cutting equipment usually adopts a structure with a movable gantry and laser head. Its design focuses on improving cutting speed and accuracy, and achieving efficient cutting of metal sheets by optimizing the movement trajectory of the gantry and the control algorithm of the laser head.

[0004] However, during the laser cutting process, the high-energy-density laser beam will cause the local temperature of the cut part of the metal sheet to rise sharply, generating huge thermal stress. This concentrated release of heat will cause the cut edge of the metal sheet to be easily deformed, such as bending and warping. These deformations not only seriously affect the processing accuracy and product quality, but may even cause the workpiece to be scrapped, reduce production efficiency, and increase production costs. Although some existing technologies reduce the thermal stress effect by adding auxiliary support structures and optimizing cutting paths, it is still difficult to effectively control the temperature changes of the metal sheet itself, and the actual effect is not ideal. Summary of the Invention

[0005] In view of the fact that the existing technology is difficult to effectively control the temperature change of the metal sheet itself and the effect of reducing thermal stress is not ideal, an automated laser welding equipment and process based on efficient processing of metal sheets is proposed.

[0006] On the one hand, the present application provides an automated laser welding equipment based on efficient processing of metal sheets, the purpose of which is to achieve dynamic pressing, elastic clamping and heat conduction cooling of metal sheets during laser cutting, thereby effectively suppressing the bending and warping deformation of the cut edges of the metal sheets caused by high temperature, and improving the processing accuracy and product quality of the metal sheets.

[0007] The technical solution of the present invention is: an automated laser welding equipment based on efficient processing of metal plates, including a frame, a gantry slidably mounted on the frame, a welding box slidably mounted on the gantry, and a laser cutting head slidably mounted inside the welding box through a third electric slide rail. A storage rack is fixedly mounted on the inner wall of the frame, and a plurality of placement slots are provided on the outer wall of the storage rack. Corrugated plates for supporting metal plates are inserted into the interior of some of the placement slots. A clamping component for elastically clamping the metal plates is provided on the storage rack; a shaping ring is elastically mounted on the bottom of the laser cutting head, and the shaping ring is a sealed hollow copper body, which is filled with a coolant that is easily vaporized and volatilized when heated, and a heat dissipation component for accelerating the cooling speed of the shaping ring is provided on the outer wall of the shaping ring.

[0008] Furthermore, the heat dissipation component includes a heat pipe fixedly mounted on the top surface of the shaping ring and interconnected with the interior of the shaping ring, and a heat dissipation fin fixedly mounted on the outer wall of the heat pipe; the heat dissipation component also includes a limit plate fixedly mounted on the top surface of the welding chassis and a sliding groove opened on the outer wall of the heat dissipation fin for the limit plate to pass through.

[0009] Furthermore, the clamping component includes an insert block inserted into the placement groove of the remaining part, a base plate fixedly installed on the outer wall of the insert block, a fixed seat fixedly installed on the top surface of the base plate, an E-shaped sliding seat slidably installed on the outer wall of the fixed seat, a pressure plate slidably installed inside the E-shaped sliding seat for pressing the metal plate, and a threaded rod rotatably installed on the top surface of the pressure plate, and the E-shaped sliding seat is E-shaped, the outer wall of the fixed seat slides in contact with the inner wall of the E-shaped sliding seat, the outer wall of the pressure plate slides in contact with the inner wall of the E-shaped sliding seat, and the outer wall of the threaded rod is threadedly connected to the top surface of the E-shaped sliding seat.

[0010] Furthermore, the clamping component also includes a first elastic member fixedly mounted on the inner wall of the E-shaped sliding seat, and one end of the first elastic member away from the E-shaped sliding seat is fixedly connected to the outer wall of the fixed seat.

[0011] Furthermore, a mounting plate is fixedly mounted on the outer wall of the laser cutting head, a connecting rod is fixedly mounted on the top surface of the shaping ring, a lifting plate is fixedly mounted on the top end of the connecting rod, and a second elastic member is provided on the top of the lifting plate.

[0012] Furthermore, an adjusting component for adjusting the preload force of the second elastic member is provided on the top of the shaping ring.

[0013] Furthermore, the adjusting component includes a fixed cylinder fixedly mounted on the bottom surface of the mounting plate, a threaded sleeve slidably mounted on the wall of the fixed cylinder, the second elastic member is located inside the threaded sleeve, and the lifting plate is located inside the fixed cylinder.

[0014] Furthermore, the adjusting component also includes a rotating cylinder rotatably mounted on the bottom surface of the mounting plate, and the inner wall of the rotating cylinder is threadedly connected to the outer wall of the threaded sleeve.

[0015] Furthermore, the present invention also provides an automated laser welding process based on efficient processing of metal sheets, comprising the following steps: Step 1: First, insert the insert into the placement slot at the appropriate position according to the size of the metal plate, and then insert the remaining placement slot into the corrugated plate; Step 2: Place the metal sheet on the top of the corrugated plates on the rack and the top of the middle horizontal plate of the E-shaped sliding seat, and rotate the threaded rod to press the pressing plate against the metal sheet to fix the metal sheet; Step 3: The gantry slides on the frame via the first electric slide rail, driving the welding box to move to the appropriate position. The welding box then slides on the gantry via the second electric slide rail, and the laser cutting head descends inside the welding box via the third electric slide rail. During the descending process of the laser cutting head, the shaping ring also descends and presses down the metal sheet; Step 4: When the laser cutting head moves to cut the metal sheet, the shaping ring moves synchronously, and its U-shaped bottom flattens the part of the cutting edge that tends to deform, and cooperates with the clamping parts to further reduce the deformation of the metal sheet during cutting.

[0016] Beneficial effects of the present invention: 1. The E-shaped sliding seat in the clamping component cooperates with the first elastic member to apply a pulling force to the metal sheet during cutting to offset the thermal stress generated during laser cutting of the metal sheet. At the same time, the elastically installed shaping ring under the laser cutting head flattens the cut edge of the metal sheet in real time during the cutting process. When the laser cutting head moves, the shaping ring moves synchronously, and its U-shaped bottom fits the sheet, cooperating with the pressure provided by the second elastic member to promptly flatten the cutting edge with a tendency to deform.

[0017] 2. During the cutting process, the copper shaping ring, together with the vaporization and condensation cycle of the coolant inside it, and the heat dissipation components composed of heat pipes and heat dissipation fins, can quickly dissipate the heat generated by the cutting of the metal sheet, avoiding deformation of the metal sheet due to local high temperature, effectively suppressing the thermal deformation of the metal sheet, and greatly reducing deformation problems such as bending and warping of the cutting edge.

[0018] 3. By rotating the rotating cylinder, the threaded sleeve is driven to rise and fall to adjust the preload force of the second elastic part, thereby changing the pressure of the shaping ring on the plate, adapting to metal materials of different hardness and thickness. In addition, the placement slots on the storage rack can be flexibly inserted with plugs and corrugated plates according to the size of the plate, and the clamping spacing can be quickly adjusted. Therefore, whether it is different materials such as stainless steel, aluminum alloy, or metal plates of different specifications such as thin plates and thick plates, efficient processing can be achieved through simple adjustment, which broadens the application scenarios of this equipment and meets the diversified production needs of the manufacturing industry.

[0021] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0022] Example 1, with reference to Figures 1-9, which is a first embodiment of the present invention, provides: an automated laser welding equipment based on efficient processing of metal plates, including a frame 1, a gantry 2 slidably mounted on the frame 1, a welding box 3 slidably mounted on the gantry 2, and a laser cutting head 5 slidably mounted inside the welding box 3 through a third electric slide rail 4, the inner wall of the frame 1 is fixedly mounted with a storage rack 7, the outer wall of the storage rack 7 is provided with a plurality of placement grooves 8, some of the placement grooves 8 are inserted with corrugated plates 6 for supporting metal plates, and the storage rack 7 is provided with a clamping component 9 for elastically clamping the metal plate; a shaping ring 17 is elastically mounted on the bottom of the laser cutting head 5, and the shaping ring 17 is a sealed hollow copper body, the interior of which is filled with a coolant that is easily vaporized and volatilized when heated, and the outer wall of the shaping ring 17 is provided with a heat dissipation component 29 for accelerating the cooling speed of the shaping ring 17.

[0023] Specifically, the gantry 2 slides on the frame 1 through the first electric slide rail (not numbered in the figure), the welding box 3 slides on the gantry 2 through the second electric slide rail (not numbered in the figure), and the laser cutting head 5 rises and falls inside the welding box 3 through the third electric slide rail 4. The laser cutting head 5 is located at the center position of the shaping ring 17.

[0024] The bottom vertical cross-section of the shaping ring 17 is U-shaped. When the laser cutting head 5 descends to cut the metal sheet on the corrugated plate 6, the shaping ring 17 falls on the metal sheet. When the laser cutting head 5 moves, the shaping ring 17 moves synchronously. The shaping ring 17 flattens the cutting edge of the metal sheet that has a tendency to deform, and cooperates with the clamping parts 9 on both sides of the metal sheet to further reduce the degree of deformation of the metal sheet during cutting. At the same time, the copper shaping ring 17 absorbs heat from the metal sheet, and the coolant inside the shaping ring 17 needs to absorb heat to evaporate, which is beneficial to accelerate the heat dissipation effect of the shaping ring 17 and the cutting edge of the metal sheet.

[0025] Reference Figure 6-Figure 8 The outer wall of the laser cutting head 5 is fixedly mounted with a mounting plate 18, the top surface of the shaping ring 17 is fixedly mounted with a connecting rod 22, the top of the connecting rod 22 is fixedly mounted with a lifting plate 28, and the top of the lifting plate 28 is provided with a second elastic member 23.

[0026] Specifically, the second elastic member 23 can be a compression spring or a return spring commonly used in the prior art. Here, it is preferably a compression spring. When the laser cutting head 5 descends and drives the shaping ring 17 to descend, the lifting plate 28 squeezes the second elastic member 23. The elastic force generated by the second elastic member 23 can increase the pressure of the shaping ring 17 on the metal sheet, thereby promoting the shaping ring 17 to flatten the cutting edge part of the metal sheet that has a tendency to deform.

[0027] Reference Figure 9The heat dissipation component 29 includes a heat pipe 24 fixedly mounted on the top surface of the shaping ring 17 and interconnected with the interior of the shaping ring 17, and a heat dissipation fin 26 fixedly mounted on the outer wall of the heat pipe 24; the heat dissipation component 29 also includes a limit plate 25 fixedly mounted on the top surface of the welding machine box 3 and a sliding groove 27 opened on the outer wall of the heat dissipation fin 26 for the limit plate 25 to pass through.

[0028] Specifically, the top of the heat pipe 24 is set upward. When the coolant inside the shaping ring 17 absorbs heat and vaporizes and moves upward to the top of the heat pipe 24, during the movement of the laser cutting head 5, the airflow passes through a number of heat dissipation fins 26, which can effectively dissipate heat from the surface of the heat pipe 24. The condensed coolant then flows back to the inside of the shaping ring 17, so that the shaping ring 17 absorbs the heat from the cutting edge of the metal plate, and then dissipates heat through the heat pipe 24 and the heat dissipation fins 26. The cooled shaping ring 17 continues to absorb heat from other positions of the metal plate. The reciprocating cycle effectively improves the heat dissipation effect of the cutting edge of the metal plate, and further reduces the deformation problem of the metal plate caused by thermal stress.

[0029] Reference Figure 1-Figure 5 The clamping component 9 includes an insert block 16 inserted into the rest of the placement slot 8, a base plate 10 fixedly mounted on the outer wall of the insert block 16, a fixed seat 11 fixedly mounted on the top surface of the base plate 10, an E-shaped sliding seat 12 slidably mounted on the outer wall of the fixing seat 11, a pressure plate 13 slidably mounted inside the E-shaped sliding seat 12 for pressing the metal plate, and a threaded rod 14 rotatably mounted on the top surface of the pressure plate 13. The E-shaped sliding seat 12 is E-shaped, the outer wall of the fixing seat 11 slides in contact with the inner wall of the E-shaped sliding seat 12, the outer wall of the pressure plate 13 slides in contact with the inner wall of the E-shaped sliding seat 12, and the outer wall of the threaded rod 14 is threadedly connected to the top surface of the E-shaped sliding seat 12. The clamping component 9 also includes a first elastic member 15 fixedly mounted on the inner wall of the E-shaped sliding seat 12, and the end of the first elastic member 15 away from the E-shaped sliding seat 12 is fixedly connected to the outer wall of the fixing seat 11.

[0030] Specifically, the first elastic member 15 can be a compression spring or a return spring commonly used in the prior art. When the pressure plate 13 presses and fixes the metal sheet, the two E-shaped sliding seats 12 can pull the metal sheet. If the metal sheet tends to deform due to the thermal stress of laser cutting, the two E-shaped sliding seats 12 approach each other and squeeze the first elastic member 15, and the elastic force of the first elastic member 15 can effectively reduce the degree of deformation of the metal sheet.

[0031] By rotating the threaded rod 14, the pressure plate 13 can be driven to rise or fall along the inner wall of the E-shaped sliding seat 12. It should be noted that when the plug block 16 is inserted into the placement groove 8 of the rest of the part, the top surface of the middle horizontal plate of the E-shaped sliding seat 12 is consistent in height with the top of the corrugated plate 6. When placing the metal sheet on several corrugated plates 6, it is only necessary to insert the plug block 16 into the placement groove 8 at the appropriate position, and the distance between the two E-shaped sliding seats 12 can be flexibly adjusted according to the length or width of the metal sheet. When the metal sheet tends to deform due to the thermal stress of laser cutting, the two E-shaped sliding seats 12 can pull the metal sheet to reduce the degree of deformation of the metal sheet.

[0032] Reference Figure 6-Figure 8 An adjusting component 30 for adjusting the preload force of the second elastic member 23 is provided on the top of the shaping ring 17 .

[0033] Specifically, the degree of compression of the second elastic member 23 in the initial state can be adjusted by adjusting the component 30. Then, when the laser cutting head 5 descends and drives the shaping ring 17 to descend, the lifting plate 28 further squeezes the second elastic member 23. In conjunction with the several corrugated plates 6 at the bottom of the metal sheet, the pressure of the shaping ring 17 on the metal sheet can be flexibly adjusted, which can reduce the situation where the flattening force of the shaping ring 17 is insufficient or excessive.

[0034] Reference Figure 6-Figure 8 The adjusting component 30 includes a fixed cylinder 21 fixedly mounted on the bottom surface of the mounting plate 18, a threaded sleeve 19 slidably mounted on the wall of the fixed cylinder 21, a second elastic member 23 located inside the threaded sleeve 19, and a lifting plate 28 located inside the fixed cylinder 21. The adjusting component 30 also includes a rotating cylinder 20 rotatably mounted on the bottom surface of the mounting plate 18, and the inner wall of the rotating cylinder 20 is threadedly connected to the outer wall of the threaded sleeve 19.

[0035] Specifically, the threaded sleeve 19 is a partially hollowed-out cylinder, which provides a relative sliding space between the mounting plate 18 and the threaded sleeve 19 to ensure that the threaded sleeve 19 will not separate from the mounting plate 18. By rotating the rotating cylinder 20, the threaded sleeve 19 can be driven to rise or fall, and then the top surface of the inner wall of the threaded sleeve 19 can squeeze the second elastic member 23. In addition, with the cooperation of the fixed cylinder 21, the degree of compression of the second elastic member 23 in the initial state can be adjusted.

[0036] Working principle: When this automated laser welding equipment is working, first, according to the size of the metal sheet, the insert block 16 is inserted into the placement slot 8 at the appropriate position, and then the remaining part of the placement slot 8 is inserted into the corrugated plate 6, and the metal sheet is placed on the top of several corrugated plates 6 on the rack 7 and the top surface of the middle horizontal plate of the E-shaped sliding seat 12. By rotating the threaded rod 14, the pressure plate 13 is driven to descend along the inner wall of the E-shaped sliding seat 12, so that the pressure plate 13 presses the metal sheet. When the metal sheet tends to deform due to the thermal stress of laser cutting, the two E-shaped sliding seats 12 approach each other and squeeze the first elastic member 15. Then, through the elastic force of the first elastic member 15, the two E-shaped sliding seats 12 can generate a pulling force on the metal sheet to effectively suppress its deformation and reduce the degree of deformation of the metal sheet.

[0037] Next, the gantry 2 slides on the frame 1 through the first electric slide rail (not numbered in the figure), driving the welding box 3 to move to the appropriate position. The welding box 3 then slides on the gantry 2 through the second electric slide rail (not numbered in the figure), and the laser cutting head 5 descends inside the welding box 3 through the third electric slide rail 4 to start cutting the metal sheet.

[0038] During the descent of the laser cutting head 5, the shaping ring 17 also descends. When the bottom surface of the shaping ring 17 contacts the metal sheet, the lifting plate 28 squeezes the second elastic member 23. The elastic force generated by the second elastic member 23 increases the pressure of the shaping ring 17 on the metal sheet.

[0039] When the laser cutting head 5 moves to cut the metal sheet, the shaping ring 17 moves synchronously, and its U-shaped bottom flattens the part of the cutting edge that tends to deform, and cooperates with the clamping component 9 to further reduce the deformation of the metal sheet during cutting. During the cutting process, the copper shaping ring 17 absorbs the heat of the metal sheet, and the coolant inside, which is easily vaporized when heated, absorbs the heat and vaporizes, and moves upward to the top through the heat pipe 24 connected to the inside of the shaping ring 17. When the laser cutting head 5 moves, it drives the heat dissipation component 29 to move, and the air flow passes through the heat dissipation fins 26 to dissipate heat on the surface of the heat pipe 24. The coolant condenses and flows back to the inside of the shaping ring 17. This cycle continuously takes away the heat from the cutting edge of the metal sheet. According to actual usage, an additional fan can be installed to blow towards the heat dissipation fins 26 to improve the heat dissipation efficiency. In addition, the threaded sleeve 19 can be driven up or down by rotating the rotating cylinder 20 to adjust the degree of compression of the second elastic member 23 in the initial state, thereby flexibly adjusting the pressure of the shaping ring 17 on the metal sheet to avoid insufficient or excessive flattening force, further ensuring the stability of the metal sheet cutting process, reducing deformation problems caused by thermal stress, and realizing efficient and high-precision processing of metal sheets.

[0040] Example 2, reference Figures 1-9, which is a second embodiment of the present invention, provides: an automated laser welding process based on efficient processing of metal sheets, using automated laser welding equipment based on efficient processing of metal sheets, comprising the following steps: Step 1: First, insert the insert 16 into the placement slot 8 at the appropriate position according to the size of the metal plate, and then insert the remaining portion of the placement slot 8 into the corrugated plate 6; Step 2: Place the metal sheet on the top of the corrugated plates 6 on the rack 7 and the top surface of the middle horizontal plate of the E-shaped sliding seat 12, and rotate the threaded rod 14 to press the pressing plate 13 against the metal sheet to fix the metal sheet; Step 3: The gantry 2 slides on the frame 1 via the first electric slide rail (not numbered in the figure), driving the welding box 3 to move to the appropriate position. The welding box 3 then slides on the gantry 2 via the second electric slide rail (not numbered in the figure). The laser cutting head 5 descends inside the welding box 3 via the third electric slide rail 4. During the descent of the laser cutting head 5, the sizing ring 17 also descends to press down the metal sheet. Step 4: When the laser cutting head 5 moves to cut the metal sheet, the shaping ring 17 moves synchronously, and its U-shaped bottom flattens the part of the cutting edge that tends to deform, and cooperates with the clamping part 9 to further reduce the deformation of the metal sheet during cutting.

[0041] Step 5: During the cutting process, the copper shaping ring 17, the coolant inside the shaping ring 17 and the heat dissipation component 29 can continuously take away the heat from the cutting edge of the metal sheet, effectively suppressing the thermal deformation of the metal sheet.

[0042] Step 6: By rotating the rotating cylinder 20 to drive the threaded sleeve 19 to rise and fall, the initial compression degree of the second elastic member 23 is adjusted, and the pressure of the shaping ring 17 on the plate can be flexibly adjusted according to the material and thickness of the metal plate.

[0043] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
