Description

Technical Field

[0001] This utility model relates to the field of rear longitudinal beam processing technology, specifically a rear longitudinal beam processing cutting dust adsorption device. Background Technology

[0002] In the machining of rear longitudinal beams (one of the core processes in automobile manufacturing), table saw cutting is a critical step. However, the traditional cutting process has serious dust and debris problems, which restrict production safety and work efficiency: debris splashing causes serious pollution and high cleaning costs: the rear longitudinal beams are mostly made of metal, and a large amount of metal debris and dust are generated during cutting. Traditional table saws do not have a special adsorption and blocking structure. The debris splashes at a speed of 5-10m / s, which not only scatters on the workbench, the ground and equipment gaps, increasing the amount of manual cleaning (cleaning takes 1-2 hours per shift), but also easily enters the table saw transmission parts, causing jamming, increasing the equipment maintenance frequency by 30%. At the same time, the dust is suspended in the air, and long-term inhalation can cause respiratory diseases and endanger the health of operators.

[0003] Poor adaptability and insufficient protection for workpieces of different sizes: The size of the rear longitudinal beam varies with the vehicle model (length 1.5-3m, width 0.2-0.5m). Traditional protective devices (such as fixed baffles) are designed with a single size and cannot fit workpieces of different widths. The protective gap is 5-10cm, and debris can easily overflow from the gap. In addition, there is a lack of telescopic adjustment function. When changing workpieces, the baffles need to be removed, which is cumbersome. Changing a single workpiece takes 5-10 minutes and affects the continuity of production.

[0004] Low dust collection efficiency and high environmental compliance risks: Some simple dust collection devices only have air inlets on one side of the table saw, with limited suction coverage. The collection rate of debris with large splash angles is less than 40%, and the concentration of uncollected dust emissions far exceeds the "Integrated Emission Standard of Air Pollutants" (GB16297-1996), posing a risk of environmental penalties to enterprises. In addition, the collected dust is mixed with debris and requires additional sorting and processing, further increasing environmental costs.

[0005] Therefore, there is an urgent need for a dust adsorption device for the processing and cutting of rear longitudinal beams that combines "all-round blocking, high-efficiency adsorption, and multi-size adaptation" to solve the above-mentioned technical problems. Utility Model Content

[0006] The purpose of this invention is to provide a dust adsorption device for the processing and cutting of rear longitudinal beams, so as to solve the above-mentioned technical problems.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a dust adsorption device for processing and cutting rear longitudinal beams, comprising a table saw, a mounting plate, and a baffle. A buckle is fixedly installed on the top of one side of the baffle. Slide rail grooves are respectively opened on both sides of the table saw. A slide rail is movably connected inside the slide rail groove. A dust collection component is provided at the other end of the slide rail, wherein there are two sets of dust collection components.

[0008] Preferably, the dust collection assembly includes: a ventilation box, which is fixedly installed on the other side of the baffle by a corner bracket, and the bottom of one side of the ventilation box is fixedly installed with a slide rail; a fixing plate, which is fixedly installed on the bottom of the ventilation box; an air pump, which is fixedly installed on one side of the fixing plate; and a filter box, which is fixedly installed on one side of the fixing plate.

[0009] Preferably, a ventilation hole is provided on one side of the ventilation box, and a ventilation pipe is connected inside the ventilation hole. One end of the ventilation pipe is connected to the input end of the air pump, and an air outlet pipe is connected to the output end of the air pump. An air outlet is provided on the top of the filter box, and the interior of the air outlet is connected to the other end of the air outlet pipe.

[0010] Preferably, a tray is fixedly installed on one side of the inner wall of the filter box, a filter cylinder is provided on the top of the tray, an air outlet is provided on the other side of the filter box, and a door is installed on the front of the filter box by hinges.

[0011] Preferably, a telescopic hole is provided at the bottom of the other side of the ventilation box, and a telescopic assembly is provided inside the telescopic hole. Preferably, there are two sets of telescopic assemblies, and the telescopic assembly includes: a telescopic rod, there are two sets of telescopic rods, which are movably connected inside the telescopic hole; and a protective cloth, which is covered on the surface of the telescopic rod.

[0012] Preferably, a small fixing plate is fixedly installed at the other end of the telescopic rod, and a spring is provided between the telescopic rods. One end of the spring is fixedly connected to the small fixing plate, and the other end of the spring is fixedly connected to the inner wall of the telescopic hole.

[0013] This utility model provides a dust adsorption device for machining and cutting rear longitudinal beams. It has the following beneficial effects:

[0014] 1. This utility model significantly improves the efficiency of dust and debris control through a synergistic structure of "flexible blocking + negative pressure adsorption," ensuring the safety of the working environment and equipment. In terms of blocking, two sets of dust-collecting components drive the baffle to close along the slide rail, with the top of the baffle fixed by buckles, forming protective barriers on both sides. Simultaneously, the telescopic rod of the telescopic component, under the action of spring force, drives the small fixed plate to press tightly against the side of the rear longitudinal beam. The protective cloth expands and contracts with the telescopic rod, filling the gap between the baffle and the workpiece, blocking more than 90% of splashing debris at the source.

[0015] At the adsorption level, the air pump generates negative pressure after starting, drawing in residual dust and fine debris through the ventilation holes of the ventilation box. The dust and debris are then transported to the filter cartridge of the filter box through the ventilation pipe and the exhaust pipe. The filter cartridge uses a HEPA high-efficiency filter with a dust filtration efficiency of ≥99%. The purified air is discharged from the exhaust port, and the emission concentration meets environmental protection standards.

[0016] 2. This utility model, through its adjustable structure of "sliding rails + elastic telescopic movement," perfectly adapts to rear longitudinal beams of different sizes, significantly improving production continuity. When the size is suitable, the dust collection component slides along the sliding rails on both sides of the table saw, allowing adjustment of the baffle spacing according to the length of the rear longitudinal beam. The sliding process is smooth and without jamming. For width variations, the telescopic rod of the telescopic component automatically extends and retracts—when placing a workpiece, the workpiece presses against the small fixed plate, causing the telescopic rod to retract and the spring to compress; after the workpiece is placed, the spring rebounds, pushing the telescopic rod to extend, ensuring the protective cloth tightly adheres to the side of the workpiece. No manual adjustment is required, and single workpiece changeover time is ≤1 minute. Furthermore, the door design on the front of the filter box facilitates quick filter cartridge replacement, eliminating the need to disassemble the equipment during cleaning, further reducing downtime and increasing single-shift production efficiency by over 20%, thus meeting the batch processing needs of rear longitudinal beams for multiple car models in automotive manufacturing.

[0027] A preferred embodiment of the dust adsorption device for rear longitudinal beam machining and cutting provided by this utility model is shown in Figures 1-4: The dust adsorption device for rear longitudinal beam machining and cutting includes a table saw 1, a mounting plate 2, and a baffle 3. A buckle 5 is fixedly installed on the top of one side of the baffle 3. Slide rail grooves are respectively opened on both sides of the table saw 1. A slide rail 4 is movably connected inside the slide rail groove. A dust collection assembly 6 is provided at the other end of the slide rail 4. The dust collection assembly 6 has two sets. The dust collection assembly 6 includes: a ventilation box 611, which is fixedly installed on the other side of the baffle 3 by a corner bracket. The bottom of one side of the ventilation box 611 is fixedly installed to the slide rail 4; a fixing plate 613, which is fixedly installed at the bottom of the ventilation box 611; an air pump 614, which is fixedly installed on one side of the fixing plate 613; and a filter box 616, which is fixedly installed on one side of the fixing plate 613. A ventilation hole is opened on one side of the ventilation box 611. A ventilation pipe 612 is connected inside the ventilation hole. One end of the filter box 616 is connected to the input end of the air pump 614, and the output end of the air pump 614 is connected to an air outlet pipe 615. An air outlet is provided on the top of the filter box 616.

[0028] The filter box 616 is connected to the other end of the air outlet 615. A tray 618 is fixedly installed on one side of the inner wall of the filter box 616. A filter cylinder 617 is set on the top of the tray 618. An air outlet 619 is opened on the other side of the filter box 616. A door is installed on the front of the filter box 616 by hinge. By turning on the air pump 614, the debris enters the ventilation pipe 612 through the ventilation box 611, and is then discharged to the filter cylinder 617 through the air outlet 615 from the output end of the air pump 614. Open one side panel of the filter box 616 and take out the filter cylinder.

[0029] The ventilation box 611 has a telescopic hole on its other side bottom. A telescopic assembly 7 is installed inside the telescopic hole. The telescopic assembly 7 has two sets, each including: two telescopic rods 714, each movably connected inside the telescopic hole; a protective cloth 711, covering the surface of the telescopic rods 714; a small fixing plate 712 fixedly installed at the other end of each telescopic rod 714; and a spring 713 between the telescopic rods 714. One end of the spring 713 is fixedly connected to the small fixing plate 712, and the other end is fixedly connected to the inner wall of the telescopic hole. The dust collection assembly 6 drives the baffle 3 and the telescopic assembly 7 to open to both sides of the table saw 1 via the slide rail 4. The rear longitudinal beam 2 is placed on the surface of the table saw 1, the dust collection assembly 6 is closed inwards, and the buckle 5 on the top of the baffle 3 is fastened. The telescopic rods 714 in the telescopic assembly 7 extend and retract according to the size of the rear longitudinal beam 2, facilitating the movement of the rear longitudinal beam 2. The cutting process is carried out, and the baffle 3 and protective cloth 711 isolate the flying debris.

[0030] Working principle:

[0031] Push the two sets of vacuuming components 6 to slide along the slide rail 4 of the table saw 1 to both sides, widening the gap between the baffles 3, and place the longitudinal beam to be cut on the surface of the table saw; then push the vacuuming components to slide inward, so that the baffles are close to both sides of the longitudinal beam, and are fastened and fixed by the buckles 5 on the top of the baffles, forming initial protection.

[0032] During placement, the side of the rear longitudinal beam presses against the small fixed plate 712 of the telescopic assembly 7, causing the telescopic rod 714 to retract along the telescopic hole of the ventilation box 611, and the spring 713 is compressed synchronously. After the workpiece is placed in place, the spring rebounds, pushing the telescopic rod to extend, so that the small fixed plate is tightly attached to the side of the workpiece, and the protective cloth 711 unfolds with the telescopic rod, filling the gap between the baffle and the workpiece, and achieving a flexible seal.

[0033] The table saw 1 is started to cut the rear longitudinal beam. Most of the metal debris produced is blocked by the baffle 3.

[0034] The protective cloth 711 blocks and prevents splashing; at the same time, the air pump 614 of the dust collection component 6 is activated, and the air pump generates negative pressure, which sucks in residual dust and fine debris through the ventilation holes of the ventilation box 611.

[0035] The inhaled dust and debris are transported to the air pump input end through the ventilation pipe 612, and then discharged into the filter cartridge 617 of the filter box 616 through the air outlet pipe 615; the filter screen inside the filter cartridge intercepts the dust and debris, and the purified air is discharged from the air outlet 619, realizing efficient dust collection and purification.

[0036] After cutting, turn off the table saw and air pump, release the buckle 5, push the dust collection component 6 to slide along the slide rail 4 to both sides, and take out the processed rear longitudinal beam; open the front door of the filter box 616, take out the filter cartridge 617 from the tray 618, empty the dust and debris collected inside and put it back in to complete the cleaning; finally, reset the dust collection component and prepare for the next cutting operation.

[0038] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
