Description

Technical Field

[0001] This utility model relates to the field of sheet metal thin plate processing technology, and more specifically, to a device for slotting workpieces. Background Technology

[0002] Sheet metal processing is a comprehensive cold working process for thin metal sheets, including shearing, punching / cutting / combined cutting, bending, welding, riveting, splicing, and forming (such as car bodies). Its significant characteristic is that the thickness of the same part is consistent. Products processed by sheet metal processing are called sheet metal parts.

[0003] Currently, it is necessary to perform grooving on the surface of sheet metal sheets (the groove does not penetrate the sheet metal sheet). The purpose of grooving is to reduce the stress of subsequent bending. Currently, grooving is generally done manually using grooving equipment, which generates a lot of debris during the grooving process. At the same time, the sheet metal sheet is prone to deviation during grooving, and the limiting effect is not good. Therefore, the effect of grooving sheet metal sheets needs to be improved. Utility Model Content

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A workpiece grooving device includes a processing table, a vacuum adsorption assembly, an L-shaped limiting block, a slot, a threaded hole, a dual-axis drive mechanism, a fiber laser, and a double fixing component.

[0010] The dual-axis drive mechanism is mounted on the machining table and is connected to a fiber laser.

[0011] The double fixing components work with the slots to provide auxiliary fixation at the four corners of the sheet metal sheet.

[0012] Furthermore, the vacuum adsorption assembly includes a vacuum pump, an adsorption box, and a suction port.

[0013] The vacuum pump is fixed on the support leg of the machining table and located below the table surface.

[0024] Furthermore, a filter screen is movably installed inside the adsorption box, and a sealed door is provided on the adsorption box.

[0025] Compared with the prior art, the beneficial effects of this utility model are:

[0026] Compared to existing technologies, this application uses an L-shaped limiting block to accurately define the placement area of ​​the sheet metal sheet. Then, it employs a central vacuum adsorption and four-corner auxiliary pressing method to achieve dual positional limitation, thereby improving the fit between the sheet metal sheet and the processing table and adsorption box and ensuring a firm fixation effect. At the same time, it can reduce the probability of edge warping during the subsequent grooving process. Furthermore, the grooving is performed by laser, which has a high degree of automation and does not generate debris, resulting in a better grooving process for the sheet metal sheet.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments:

[0034] like Figures 1 to 3 As shown, a workpiece grooving device includes a processing table 1, a vacuum adsorption assembly, an L-shaped limiting block 2, a slot 3, a threaded hole (not shown in the figure), a dual-axis drive mechanism, a fiber laser 4, and a double fixing component.

[0035] The vacuum adsorption component is embedded in the processing table 1;

[0036] Four L-shaped limiting blocks 2 are fixed on the processing table 1 and are symmetrically distributed in pairs about the vacuum adsorption component;

[0037] Slot 3 is provided on L-shaped limiting block 2 and a threaded hole is provided inside slot 3;

[0038] A dual-axis drive mechanism is mounted on the processing table 1 and is connected to a fiber laser 4.

[0039] The double fixing components work together with slot 3 to provide auxiliary fixing to the four corners of the sheet metal sheet.

[0040] Specific implementation of the embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the vacuum adsorption assembly includes a vacuum pump 5, an adsorption box 6, and a suction port 7.

[0041] The vacuum pump 5 is fixed on the support leg of the processing table 1 and located below the table surface of the processing table 1.

[0042] The adsorption box 6 is embedded in the processing table 1 and connected to the vacuum pump 5. The upper surface of the adsorption box 6 is flush with the upper surface of the processing table 1.

[0043] Several suction holes 7 are provided on the adsorption box 6 and are connected to the inside of the adsorption box 6.

[0044] Specific implementation of the embodiments of this utility model, such as Figure 1 As shown, the dual-axis drive mechanism includes a mounting frame 8 and a dual-axis device 9 (the dual-axis device 9 uses a cross slide and is driven by a lead screw structure, which is existing technology and its working principle will not be described).

[0045] Mounting bracket 8 is fixed on processing table 1, and a dual-axis device 9 connected to fiber laser 4 is installed on mounting bracket 8.

[0046] Specific implementation of the embodiments of this utility model, such as Figure 1 As shown, the dual-fixing assembly includes a pressure plate 10, an insert block 11, and fixing bolts 12.

[0047] The pressure plate 10 is welded with inserts 11 that correspond one-to-one with the slots 3 and are of the appropriate size;

[0048] The insert 11 has a mounting hole (not shown in the figure);

[0049] The fixing bolt 12 passes through the mounting hole and mates with the threaded hole.

[0050] To avoid the probability of external impurities entering through the suction port 7 and subsequently damaging the vacuum pump 5, further optimizations to the above-described embodiment are made, such as... Figure 1 As shown, a filter screen 14 is movably installed inside the adsorption box 6, and a sealing door 15 is provided on the adsorption box 6. If external impurities enter the adsorption box 6 through the suction hole 7, they will adhere to the filter screen 14. The filter screen 14 can be replaced by periodically opening the sealing door 15. The amount of impurities entering through the suction hole 7 is small, and the impact of periodically replacing the filter screen 14 on the adsorption effect is negligible. The locking of the sealing door 15 and the adsorption box 6 can be achieved using existing technology, which will not be elaborated here.

[0051] In order to reduce the probability of wear on the sheet metal surface during the initial placement of the sheet metal sheet and the double-limiting sheet metal sheet, the above embodiment is further optimized by providing rubber pads on both the pressure plate 10 and the L-shaped limiting block 2. The rubber pads are not shown in the figure.

[0052] It should be noted that the fiber laser 4, vacuum pump 5, and biaxial device 9 are all electrically connected to the controller, which is not labeled in the figure.

[0053] The working process of this utility model is as follows:

[0054] First, place the sheet metal sheet of a fixed size that needs to be slotted onto the processing table 1. During the placement process, the four L-shaped limiting blocks 2 can contact the four corners of the sheet metal sheet to accurately define the placement position of the sheet metal sheet. After placement, the sheet metal sheet can cover all the suction holes 7. Then, the vacuum pump 5 is controlled by the controller to work, so that the center part of the sheet metal sheet can be firmly adsorbed onto the processing table 1. (It should be noted that during the adsorption of the center part of the sheet metal sheet, you can press it to improve the fit and thus the adsorption effect is better.)

[0055] After adsorption is complete, a set of double fixing components is installed on each L-shaped limiting block 2 to further limit the sheet metal sheet. The double fixing components have two purposes: first, they can make the remaining area of ​​the sheet metal sheet fit better with the surface of the processing table 1; second, they can reduce the probability of edge warping due to stress during the subsequent laser grooving process.

[0056] After the center adsorption and surrounding limit are completed, the dual-axis equipment 9 is controlled by the controller to operate, which in turn drives the fiber laser 4 to accurately groove the sheet metal sheet according to the preset running trajectory and speed (grooving depth remains unchanged). After grooving is completed, the double fixing components and vacuum adsorption are released one after another to unload the sheet metal sheet and then carry out the bending process.

[0057] To promptly dissipate the heat generated during the laser grooving process and reduce the probability of thermal deformation in the sheet metal, in some embodiments, such as... Figure 4 As shown, a cooling pipe 13 (higher than the fiber laser 4) is fixed on the dual-axis device 9 and is inclined and located on one side of the fiber laser 4. The cooling pipe 13 is connected to an air pump through a hose, and the air pump is connected to a nitrogen source. The air pump and the nitrogen source are not shown in the figure. In this embodiment, nitrogen is blown to cool the sheet metal while laser grooving is performed to further reduce the probability of warping after grooving the sheet metal sheet.

[0058] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model.
