Description

Technical Field

[0001] This invention relates to the field of laser cutting technology, and in particular to a processing device for trimming and notching stamped parts such as automotive crossbeams. Background Technology

[0002] Automotive crossbeams are key load-bearing components in automotive mechanical engineering, playing a crucial role in the chassis. They not only enhance the chassis's torsional rigidity and bear longitudinal loads but also support critical automotive parts. Generally, trucks and similar vehicles are equipped with 5-6 crossbeams, or even more. The design characteristics of beam-type chassis facilitate the installation of cabs, cargo boxes, and various specialized equipment, which also provides convenience for vehicle modification and the development of multiple vehicle models. Therefore, they are widely used in the truck and special-purpose vehicle sectors.

[0003] Automotive crossbeam stamping parts are generally formed directly from steel or aluminum. After stamping, the parts need to be trimmed and notched. To ensure the accuracy of trimming and to accommodate the processing of various crossbeam stamping parts, laser cutting machines are currently used for trimming and notching. Laser cutting machines offer high precision and strong adjustability, and can perform trimming and notching on crossbeam stamping parts of various shapes.

[0004] Existing laser cutting machines present two significant problems when trimming and notching stamped workpieces with a "U"-shaped cross-section. First, the molten slag produced by laser cutting easily sputters and adheres to the inner wall of the groove in the workpiece. This molten slag can affect subsequent spraying and assembly operations, and the slag adhesion area is also more prone to corrosion. Second, during laser cutting, when the long side is cut halfway, the waste edge that detaches from the body is in a suspended state and will swing, causing slight deformation in the area being cut by the laser, thus affecting the processing accuracy. Summary of the Invention

[0005] The purpose of this invention is to provide a processing equipment for trimming and notching stamped parts of automobile crossbeams, which aims to solve the problems in the prior art where welding slag easily accumulates on the inner wall of the groove of the workpiece when the laser cutting machine processes the stamped parts, and the wobbling of the waste edge during cutting affects the laser cutting.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution: A processing device for trimming and notching stamped parts of automobile crossbeams includes a laser, a worktable on one side of the laser, a support member on the worktable, the support member being "I"-shaped, a lifting cylinder at the bottom of the support member, multiple pressing components for clamping workpieces on both sides of the support member, movable parts on both sides of the support member, each movable part including a movable block, a flat support plate horizontally mounted on the movable block, a first cleaning plate vertically mounted on the end of the flat support plate near the support member, a second cleaning plate horizontally mounted on the top of the first cleaning plate near the support member, an electric push rod mounted on the movable block and connected to the flat support plate, and a drive mechanism on the worktable for driving the movable parts to move horizontally.

[0007] With the above technical solution, before processing the workpiece, the height of the support component is adjusted by the lifting cylinder according to the size of the workpiece to ensure that the bottom surface of the workpiece is not lower than the top of the flat support plate when the workpiece is placed on the support component. After the workpiece is placed on the support component, the top of the support component contacts the inner wall of the groove of the workpiece. The pressing component presses the workpiece firmly on the support component. Then the laser starts to cut the waste edge of the workpiece. When the laser cuts a short distance, the drive mechanism controls the moving part to start moving towards the workpiece. The flat support plate supports one end of the waste edge and then moves forward with the laser. Since the waste edge is always supported by the flat support plate, it is avoided that the waste edge is suspended and shakes. The position of the laser cutting will not be deformed, and the cutting accuracy is higher. At the same time, when the laser is cutting, the molten slag will splash onto the inner wall of the groove of the workpiece. When the moving part moves with the laser, the first cleaning plate scrapes off the molten slag on the side wall of the groove, and the second cleaning plate scrapes off the molten slag on the upper wall of the groove, realizing timely cleaning of the molten slag.

[0008] A further feature of the present invention is that: a movable cavity is provided inside the movable block, and an elongated movable hole is provided at the top of the movable block, the movable hole communicating with the movable cavity; an "L"-shaped movable rod is provided inside the movable cavity, the top end of the movable rod being detachably connected to the bottom of the flat support plate, and the other end of the movable rod being connected to the electric push rod.

[0009] With the above technical solution, the first cleaning plate, the second cleaning plate and the flat support plate of different sizes can be replaced according to the workpiece of different sizes. It is only necessary to disassemble the flat support plate and the movable rod for replacement. The electric push rod can control the flat support plate, the first cleaning plate and the second cleaning plate to move back and forth.

[0010] A further feature of the present invention is that a connecting screw is provided at the bottom of the flat support plate, and a connecting threaded hole that mates with the connecting screw is provided at the top of the movable rod.

[0011] The above technical solution enables the installation and disassembly of the flat support plate and the movable rod through the cooperation of the connecting screw and the connecting threaded hole.

[0012] A further feature of the present invention is that the driving mechanism includes a driving screw, one end of which is provided with a driving motor, and the movable block is provided with a driving threaded hole that cooperates with the driving screw.

[0013] The above technical solution uses a drive motor to control the rotation of the drive screw, and through the cooperation of the drive screw and the drive threaded hole, the translational drive of the moving block is achieved.

[0014] A further feature of the present invention is that: both ends of the movable block are provided with accordion covers, and the drive screw is located inside the accordion covers.

[0015] Through the above technical solution, the bellows cover protects the drive screw and prevents welding slag from falling onto the screw and affecting the movement of the moving block.

[0016] A further provision of the present invention is that: a rotary table is provided below the worktable, a rotary motor is provided below the rotary table, multiple worktables are provided, multiple worktables are provided on the same rotary table, and a partition is provided between two adjacent worktables.

[0017] The above technical solution allows for the setting of multiple worktables on a rotary table, enabling multi-station operation. After one workpiece is processed, the rotary table rotates, allowing the laser to cut the workpiece on the next worktable. The workpiece on the already processed worktable is then disassembled and the slag is cleaned. The processing and disassembly of the workpiece are carried out at the same time, resulting in higher work efficiency.

[0018] A further configuration of the present invention is as follows: the pressing component includes a fixed block and a pressing claw, an adjusting motor is provided on the fixed block, one end of the pressing claw is connected to the adjusting motor, and a rubber anti-slip plate is provided on the movable end of the pressing claw.

[0019] The above technical solution involves adjusting the motor to control the rotation of one end of the lower pressure claw, while the other end of the lower pressure claw presses the workpiece tightly against the support, thus fixing the workpiece. Adjusting the motor to rotate in the opposite direction unlocks the workpiece.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention uses an "I"-shaped support to create a barrier zone inside the workpiece groove. When the laser cuts the waste edge, the molten slag will only splash onto one side and the top of the workpiece's inner wall. Then, the movable block follows the movement of the laser, and the first and second cleaning plates scrape off the welding slag adhering to one side and the top of the workpiece's inner wall, achieving timely cleaning of the inner wall of the workpiece groove. At the same time, the flat support plate holds the waste edge in place, preventing it from wobbling and causing deformation at the cutting point, thus improving cutting accuracy. 2. The present invention uses movable parts on both sides of the support member. When the workpiece is finished and a notch needs to be cut on the workpiece, the support member descends and the movable parts provide support on both sides of the workpiece. Then, the downward pressure claw is used to fix the workpiece, ensuring that there is no obstruction directly below the workpiece. Notch cutting processing can be performed on the top and sides of the workpiece, which is simple and convenient. 3. By setting up an electric push rod, after the notch is processed, the electric push rod controls the translation of two first cleaning plates and two second cleaning plates, which can realize the cleaning of welding slag on each surface of the inner wall of the workpiece groove.

[0024] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0025] This invention provides a processing device for trimming and notching stamped parts of automobile crossbeams, such as... Figures 1 to 5 As shown, the system includes a laser 1, a worktable 2 on one side of the laser 1, a support 3 on the worktable 2, the support 3 being I-shaped, and two lifting cylinders 4 installed at the bottom of the support 3 for controlling its lifting. A movable component 6 is located on each of the left and right sides of the support 3. Each movable component 6 includes a movable block 6a, which is cubic in shape, and an electric push rod 6e is mounted on the movable block 6a. A flat support plate 6b is horizontally mounted on the movable component 6. A first cleaning plate 6c is vertically mounted on one end of the flat support plate 6b near the support 3. A second cleaning plate 6d is horizontally mounted on the top of the first cleaning plate 6c near the support 3. The two ends of the first cleaning plate 6c are fixedly connected to the flat support plate 6b and the second cleaning plate 6d, respectively. Multiple pressing assemblies 5 for pressing workpieces 11 are located on both sides of the support 3. A drive mechanism 7 for driving the movable component 6 to move horizontally is located on each side of the support 3.

[0026] The laser 1 is a common five-axis laser in the field, which can cut the workpiece 11 at various angles. The length of the support 3 is less than the length of the workpiece 11. After the workpiece 11 is placed on the support 3, the two ends of the workpiece 11 do not contact the support 3, which facilitates the laser 1 to cut the ends of the workpiece 11. The width of the horizontal plate at the top of the support 3 is less than the width of the inner wall of the workpiece 11, leaving space for the first cleaning plate 6c and the second cleaning plate 6d to move inside the groove of the workpiece 11. Two lifting cylinders 4 are located at the bottom ends of the support 3 respectively and lift and lower synchronously to ensure that the lifting and lowering of the support 3 is stable. The sum of the width of the second cleaning plate 6d on both sides and the width of the horizontal plate at the top of the support 3 should be equal to the width of the groove inside the workpiece 11. Before installing workpiece 11, the height of support 3 can be controlled by lifting cylinder 4 to ensure that when workpiece 11 is placed on support 3, the second cleaning plate 6d is in contact with the top of the inner wall of the groove when it moves into the groove of workpiece 11. The width between the two first cleaning plates 6c on the left and right sides can also be controlled by electric push rod 6e. When the distance between the two second cleaning plates 6d is exactly equal to the width of workpiece 11, the center line of workpiece 11 coincides with the center line of the "I"-shaped support 3, and it is placed in the center without manual adjustment. At the same time, after the workpiece 11 is trimmed, lifting cylinder 4 controls support 3 to descend, and workpiece 11 is supported only by the second cleaning plates 6d on both sides. The downward pressure component 5 provides downward pressure to fix workpiece 11. There is no obstruction on the bottom and sides of workpiece 11, which facilitates laser 1 to cut notches on the sides and top of workpiece 11.

[0027] like Figure 6 As shown, a movable cavity 6a1 is opened inside the movable block 6a, and an elongated movable hole 6a2 is opened at the top of the movable block 6a, which communicates with the movable cavity 6a1. An "L"-shaped movable rod 6f is set inside the movable cavity 6a1. The horizontal end of the movable rod 6f is connected to the electric push rod 6e, and the vertical end is provided with a connecting threaded hole. The bottom of the flat support plate 6b is fixedly connected to the connecting screw 6b1, so as to realize the detachable connection between the flat support plate 6b and the movable rod 6f. The electric push rod 6e can control the flat support plate 6b, the first cleaning plate 6c and the second cleaning plate 6d to move forward and backward. The length of the flat support plate 6b should always cover the movable hole 6a2 to prevent foreign objects from entering the movable hole 6a2.

[0028] The first cleaning plate 6c and the second cleaning plate 6d can be adjusted in real time, which has three main technical effects. First, when placing the workpiece 11, by controlling the distance between the first cleaning plates 6c, the workpiece 11 is ensured to be placed in the center, so that the workpiece 11 is evenly stressed during fixing and processing, and no area is missed when cleaning welding slag. Second, the first cleaning plate 6c can ensure that it is in close contact with the inner wall of the groove of the workpiece 11, so as to clean the slag on the inner wall of the groove of the workpiece 11 in a timely manner. Third, since the combined length of the two second cleaning plates 6d is less than the width of the groove of the workpiece 11, after the second cleaning plates 6d have cleaned the two sides of the top of the inner wall of the groove of the workpiece 11, the two second cleaning plates 6d move towards each other to clean the areas that have not been contacted again, so as to achieve complete cleaning of the inner wall of the groove of the workpiece 11.

[0029] like Figure 5 and Figure 6 As shown, the drive mechanism 7 includes a drive screw 7a, with a drive motor 7b at one end. The movable block 6a has a drive threaded hole that mates with the drive screw 7a. The drive motor 7b drives the drive screw 7a to rotate forward or backward. The movable block 6a moves forward or backward under the combined action of the drive screw 7a and the drive threaded hole, thus achieving horizontal displacement of the movable block 6a. To prevent welding slag generated during laser cutting from falling onto the drive screw 7a, a bellows cover 7c is installed on the outside of the drive screw 7a. Bellows covers 7c are installed at both ends of the movable block 6a. Regardless of whether the movable block 6a moves forward or backward, the bellows cover 7c can cover the drive screw 7a, preventing welding slag from falling onto the drive screw 7a and affecting the movement of the movable block 6a.

[0030] like Figure 1 and Figure 3 As shown, there are three worktables 2, which are located on a rotary table 8. A rotary motor 9 is installed below the rotary table 8, which controls the rotation of the rotary table 8, thereby driving the three worktables 2 to rotate simultaneously. A partition 10 is installed between the two worktables 2 of the two rows. The three worktables 2 divide the working area into three zones. The processing zone is used for the laser 1 to cut the workpiece 11. After processing, the worktable 1 rotates 120° to the unloading zone to unload the processed workpiece 11. After cleaning the worktable 2, a new workpiece 11 to be processed is placed on it. Then the worktable 2 rotates 120° to the adjustment zone to adjust the position of the workpiece 11. After the workpiece 11 is fixed, the worktable 2 rotates 120° to the processing zone for processing. This cycle is repeated, and loading, unloading, position adjustment and laser processing can be performed at the same time, resulting in high work efficiency.

[0031] like Figure 5As shown, the pressing-down component 5 includes a fixed block 5a and a pressing-down claw 5b. An adjusting motor 5c is installed on the fixed block 5a. One end of the pressing-down claw 5b is connected to the adjusting motor 5c. The adjusting motor 5c controls the rotation of one end of the pressing-down claw 5b to achieve fastening and locking or unlocking of the workpiece 11. A rubber anti-slip sheet is provided on the movable end of the pressing-down claw 5b to increase the friction between the pressing-down claw 5b and the surface of the workpiece 11 and prevent the workpiece 11 from sliding.

[0032] As Figure 7 shown, in this technical solution, the workpiece 11 to be processed is in a "V" shape before cutting. There are waste edges remaining after stamping on both sides of the workpiece 11. It is necessary to cut off the waste edges on both sides, and it is also necessary to cut and process multiple slits on the top or both side surfaces of the workpiece 11 for subsequent installation.

[0033] As Figure 8 shown, when the support member 3 rises to support the workpiece 11, trimming is performed at this time to cut off the waste edges on both sides. The first cleaning plate 6c and the second cleaning plate 6d scrape the slag from the inner wall of the groove of the workpiece 11. As Figure 9 shown, after the support member 3 descends, the two second cleaning plates 6d support the workpiece 11. After the workpiece 11 is cut with slits, the two second cleaning plates 6d extend relatively and clean the slag at the middle position of the top of the inner wall of the groove of the workpiece 11.

[0034] The working process steps and principles of this technical solution are as follows: S1. Position setting: Based on the size of the workpiece 11, set the rising height of the support member 3 to ensure that after the workpiece 11 is placed on the support member 3, the top of the second cleaning plate 6d is flush with the top of the inner wall of the groove of the workpiece 11, and the top of the flat support plate 6b is slightly lower than the bottom of the workpiece 11; set the advancing height of the electric push rod 6e. When the electric push rod 6e advances to the first length, the first cleaning plate 6c fits against the side of the inner wall of the groove of the workpiece 11. When the electric push rod 6e advances to the second length, the adjacent sides of the two second cleaning plates 6d are coplanar. S2. Fixing the workpiece 11: Push the electric push rod 6e to the second length. At this time, the distance between the opposite sides of the two first cleaning plates 6c is equal to the width of the groove of the workpiece 11. Turn the groove of the workpiece 11 downward and buckle it on the support member 3. At this time, the first cleaning plate 6c and the second cleaning plate 6d are located in the groove of the workpiece 11. Then the adjusting motor 5c controls the rotation of the pressing-down claw 5b, and the pressing-down claw 5b tightly presses the workpiece 11 on the support member 3. Then the driving motor 7b rotates to control the first cleaning plate 6c and the second cleaning plate 6d to move out of the groove of the workpiece 11 to complete the fixing of the workpiece 11. S3. Trimming Process: Rotary motor 9 controls the rotating body and worktable 2 to rotate 120° to the position adjustment area, where the position of workpiece 11 is detected and adjusted. After adjustment, worktable 2 rotates another 120° to the processing area, and laser 1 begins processing workpiece 11. When laser 1 cuts a certain distance of waste edge, drive motor 7b controls movable block 6a to move, and flat support plate 6b moves below the waste edge to support it and prevent it from wobbling. At the same time, movable block 6a moves forward with laser 1, but... Always positioned behind the laser 1, the first cleaning plate 6c and the second cleaning plate 6d are in contact with the inner wall of the groove of the workpiece 11, scraping away the slag adhering to the inner wall in time. When the laser 1 moves to the vicinity of a certain pressing claw 5b, the pressing claw 5b rotates to the other side, so as not to obstruct the movement of the laser 1. At the same time, the other pressing claws 5b keep pressing the workpiece 11. When the waste edge on one side is cut off, the laser 1 moves to the other side, and the movable block 6a on the other side moves with the laser 1 to realize the waste edge support and slag treatment. S4. Notch processing: Drive motor 7b controls the second cleaning plates 6d on both sides to move into the groove of workpiece 11. The two second cleaning plates 6d are located at both ends of workpiece 11 respectively. Then, lifting cylinder 4 controls support 3 to descend. At this time, workpiece 11 is supported from below by the two second cleaning plates 6d. There is no obstruction on the top and sides of workpiece 11. Laser 1 cuts and processes notches on the top and sides of workpiece 11. S5: Secondary cleaning of slag: When the electric push rod 6e extends to the first length, the first cleaning plate 6c and the second cleaning plate 6d scrape off the slag remaining on the inner wall of the workpiece 11 when the notch is opened. At this time, the middle area at the top of the inner wall of the groove of the workpiece 11 has not been cleaned. Then the electric rod extends to the second length, and the two second cleaning plates 6d clean the middle area at the top of the inner wall of the groove of the workpiece 11.

[0035] S6: Disassembling workpiece 11: After workpiece 11 is processed and the slag is cleaned, the rotary motor 9 controls the rotating body and the worktable 2 to continue rotating 120° and move to the loading area. The adjustment motor 5c controls the lower pressure claw 5b to unlock and remove workpiece 11. After workpiece 11 is removed, the two second cleaning plates 6d can be controlled to scrape off the slag remaining on the top of the support 3 when the notch was cut. Then the entire workpiece 11 is processed.

[0036] It should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
