The blade tip is prone to breakage during cutting, resulting in a short blade life and insufficient cutting cycles to meet the requirements of long-term continuous production. The middle section of the welded surface of the crash beam may collapse and deform, and burrs and curling may occur on the cut surface, affecting the cutting quality of the cross-section of the crash beam.

Detailed Implementation
[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.
[0033] Example 1
[0034] like Figures 1-6As shown, a cutting device for an automotive anti-collision beam roll forming production line includes: a base plate 100, two vertical plates 200, a lower cutter block fixing plate 300, two lower cutter block mounting plates 400, a lower cutter block module 500, and a cutting assembly. The two vertical plates 200 are both located on top of the base plate 100; the lower cutter block fixing plate 300 is embedded between the lower middle parts of the two vertical plates 200; the two lower cutter block mounting plates 400 are both mounted on top of the lower cutter block fixing plate 300; the lower cutter block module 500 is mounted between the two lower cutter block mounting plates 400; the cutting assembly includes an actuating cylinder fixing plate 601, which is fixedly connected to the two vertical plates 100. In the upper middle part between the vertical plates 200, a hydraulic actuation cylinder 602 is installed on the top of the actuation cylinder fixing plate 601. A cutter fixing plate is provided at the output end of the hydraulic actuation cylinder 602. A cutter mounting plate 603 is fixedly connected to the bottom of the cutter fixing plate. A cutter 604 is installed at the bottom of the cutter mounting plate 603. The cutter 604 adopts a single-point irregular triangular blade profile with a piercing sharp angle. The blade edge and handle of the cutter 604 are designed as an integral piece. By placing the anti-collision beam to be cut at the lower blade block module 500, and then activating the hydraulic actuation cylinder 602, it drives the cutter 604 to slowly fall down, finally cutting off the anti-collision beam.
[0035] like Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, the cutter 604 is provided with a sharp triangular piercing edge with an angle not exceeding 70 degrees, which facilitates piercing into the interior of the anti-collision beam and cutting the anti-collision beam.
[0036] like Figure 1 As shown, both upright plates 200 are assembled from steel plates, giving them sufficient structural strength.
[0037] like Figure 3 As shown, the lower cutting block module 500 consists of an inlet cutting block 501 and an outlet cutting block 502, and a pad is provided between the inlet cutting block 501 and the outlet cutting block 502. A cutting edge with the same cross-sectional profile as the anti-collision beam is machined in the middle of the inlet cutting block 501 and the outlet cutting block 502, which facilitates the trimming of burrs on the port section. A hollow structure is made below the cutting edge to avoid cutting waste and facilitate the falling and recycling of waste.
[0038] like Figure 1 As shown, a support plate 700 is installed on each of the two upright plates 200 on the side away from each other, and the support plate 700 is fixedly connected to the top of the base plate 100. The support plate 700 can support the upright plate 200.
[0039] like Figure 1 As shown, the base plate 100 has several mounting holes, which allow the base plate 100 to be installed.
[0040] Example 2
[0041] like Figure 7 As shown, the difference from Embodiment 1 is that: the support plate 700 is provided with an adjustment assembly for adjusting the height of the upright plate 200. The adjustment assembly includes several first threaded holes 701, which are all opened on the two upright plates 200 on opposite sides. The support plate 700 is provided with several second threaded holes 702. The first threaded holes 701 and the second threaded holes 702 are internally threaded with locking nuts 703. The base plate 100 is provided with moving assemblies around its perimeter to drive the base plate 100 to move. The moving assemblies include several hydraulic push rods 801, which are all installed around the top of the base plate 100. The output end of each hydraulic push rod 801 is provided with a universal wheel 802. The interior of the base plate 100 is provided with a limiting groove, and the universal wheel 802 is movably connected to the limiting groove. By rotating the locking mechanism... Tighten nut 703 to move it away from the first threaded hole 701 and the second threaded hole 702, thereby allowing the upright plate 200 to move. This drives the lower blade block module 500 to adjust to a suitable height, reducing limitations and broadening its applicability. After adjustment, rotate the locking nut 703 again to bring it closer to the first threaded hole 701 and the second threaded hole 702, fixing the upright plate 200 in place. Activate the hydraulic push rod 801 to drive the caster wheel 802 to rise and fall, moving it away from the limit groove to the bottom of the base plate 100. This allows the base plate 100 to move the entire device, enabling adjustments based on actual needs and further reducing limitations. After adjusting to the appropriate position, activate the hydraulic push rod 801 again to drive the caster wheel 802 into the limit groove, allowing the base plate 100 to be installed and fixed through the mounting holes.
[0042] The above embodiment discloses a cutting device for a roll forming production line of automotive anti-collision beams. During operation, the automotive anti-collision beam passes through the center cutting edge of the lower cutting block module 500 of the roll forming production line cutting device. A hydraulic cylinder 602 pushes the cutter 604 downwards. The top of the cutter 604 penetrates the weld area at the upper part of the anti-collision beam, first breaking through the upper part of the anti-collision beam from the outside in. The irregular triangular cutting edge continues to penetrate deeper into the cross-section of the anti-collision beam to perform the cutting operation. The roll forming production line cutting device continues to move downwards, and the cutting edge of the cutter 604 contacts the cross-section of the anti-collision beam. The lower part, again from the inside out, breaks through the lower part of the anti-collision beam cross-section; the roller pressing production line cutting device continues to descend until the arc part of the cutting edge of the cutter 604 crosses the lower edge of the anti-collision beam cross-section, and then finally cuts the anti-collision beam. While cutting the anti-collision beam, the cutter 604 trims the burrs in the cutting area on the cross-section of the part to ensure the quality of the cut section. The cutting force loaded by the hydraulic cylinder 602 does not change suddenly, which slows down the wear of the cutting edge, extends the service life of the cutter 604, ensures the integrity of the cut cross-section structure of the anti-collision beam, prevents deformation, and eliminates burrs.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
