Description

Technical Field

[0001] This utility model relates to the field of profile cutting equipment technology, and in particular to a hydraulic cutting tool. Background Technology

[0002] H-beams, channel steel, and angle steel, among other structural steel sections, are widely used in building and engineering structures due to their excellent mechanical and performance properties. Therefore, processing and cutting these steel sections to meet the structural requirements of buildings and other applications is crucial in steel section manufacturing. Currently, in China, H-beams and other structural steel sections are mainly cut using saw blades or gas cutting. Saw blade cutting produces waste at the cut, has low production efficiency, and requires frequent blade replacements; gas cutting is inefficient and produces poor cut quality.

[0003] Currently, for lightweight profiles such as channel steel, hydraulic cutting can be used. However, since the cross-section of channel steel is U-shaped, when using hydraulic cutting, the existing tooling clamps tend to flip outward or inward on both sides of the cut edge of the channel steel during clamping and pressing. Furthermore, the debris generated during pressing cannot be discharged quickly and tends to accumulate inside the tooling, affecting subsequent cutting.

[0004] Therefore, it is necessary to provide a new hydraulic cutting tool to solve the above-mentioned technical problems. Utility Model Content

[0025] 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. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0027] Please see Figures 1 to 6 This utility model provides a hydraulic cutting tool, which includes:

[0028] The substrate 1 has support bolts 11 fixedly installed at the four corners of its top end;

[0029] The middle partition 2 has mounting holes 201 at its four corners for connecting with the support bolts 11. Both sides of the middle partition 2 are integrally formed with side plates 21. A side clamping hydraulic cylinder 3 is installed on the outer side wall of the side plate 21. A side clamping block 31 is fixedly installed at the telescopic end of the side clamping hydraulic cylinder 3. A support column 22 is fixedly installed at each of the four corners of the top of the middle partition 2. A cutting assembly 4 is installed on the support column 22.

[0030] A receiving frame 5 is fixedly installed in the middle of the intermediate partition 2, and a chip discharge port 501 is provided through the middle of the receiving frame 5 and the intermediate partition 2. Chip sweeping components 7 are installed on both sides of the chip discharge port 501 in the middle of the receiving frame 5. The chip sweeping components 7 include a rotating plate 71, which is rotatably installed in the middle of the receiving frame 5. A gear 72 is fixedly installed at the top of the rotating plate 71. A linkage plate 73 is fixedly installed at the bottom of the side clamping block 31. A rack plate 74 is symmetrically installed at the bottom of the linkage plate 73. The rack plate 74 meshes with the corresponding gear 72.

[0031] There are two rotating plates 71, which are symmetrically distributed based on the centerline of the chip discharge port 501.

[0032] It should be noted that during use, the base plate 1 is installed on the conveyor line for cutting channel steel, and the channel steel is placed on the support frame 5 so that its cutting position is aligned with the chip discharge port 501. After alignment, the side clamping hydraulic cylinder 3 drives the side clamping block 31 to clamp both sides of the channel steel. During clamping, the linkage plate 73 also moves closer to the channel steel. Under the meshing drive of the rack plate 74 and the gear 72, the rotating plate 71 moves away from the chip discharge port 501. Then, the cutting assembly 4 is started to cut the channel steel. After cutting, when the side clamping hydraulic cylinder 3 drives the side clamping block 31 away from the channel steel, the linkage plate 73 also moves away from the channel steel. Similarly, under the meshing drive of the rack plate 74 and the gear 72, the rotating plate 71 rotates toward the chip discharge port 501, sweeping the chips on the support frame 5 out of the chip discharge port 501, thus completing the automatic chip removal.

[0033] In this embodiment: the bottom end of the intermediate partition plate 2 is equipped with a chip discharge trough 6 that is connected to the chip discharge port 501. When the rotating plate 71 rotates, the chips are sent to the chip discharge port 501 and then automatically fall into the inclined chip discharge trough 6 and are automatically discharged from the chip discharge trough 6.

[0034] In the embodiments of this utility model, please refer to Figures 1 to 6 Adjusting nuts 12 are installed on both the upper and lower sides of the mounting hole 201 on the support bolt 11;

[0035] It should be noted that when the base plate 1 is connected to the channel steel conveyor line, the middle partition plate 2 can be adjusted in height on the support bolt 11 by adjusting the adjusting nut 12, so that the support frame 5 can be better connected to the channel steel on the conveyor line.

[0036] In the embodiments of this utility model, please refer to Figures 1 to 6The middle part of the support frame 5 is provided with pads 51 at both the front and rear ends of the chip discharge port 501. The top of the support frame 5 is equipped with a positioning plate 52. The bottom end of the positioning plate 52 is equipped with an inner support block 53 corresponding to the pads 51. The top of the positioning plate 52 is provided with a cutting groove 502 for the cutting component 4 to pass through. The side clamping block 31 is provided with a through groove 301 aligned with the cutting groove 502. The support frame 5 is fixedly installed with a U-shaped support frame 54 on the outside of the pads 51. The bottom end of the U-shaped support frame 54 is rotatably installed with a support roller 55. The top end of the support roller 55 is flush with the top end of the pads 51. The top end of the U-shaped support frame 54 is provided with a sliding groove 503. A pressure roller 56 is slidably installed in the sliding groove 503.

[0037] The cutting assembly 4 includes an upper top plate 41, which is detachably mounted on the support column 22. A main hydraulic cylinder 42 is fixedly mounted in the middle of the upper top plate 41. A knife holder 43 is fixedly mounted at the telescopic end of the main hydraulic cylinder 42. A knife groove is provided at the bottom end of the knife holder 43, and a pressure cutting knife 44 is detachably mounted in the knife groove.

[0038] It should be noted that when the support frame 5 is carrying the channel steel, one end of the channel steel passes over the support roller 55 on the U-shaped support frame 54 and then lies flat on the pad 51. When the channel steel is inserted into the support frame 5, the inner support block 53 on the positioning plate 52 is inserted into the inside of the channel steel simultaneously to position and support both sides of the channel steel. When the channel steel moves, it is controlled to cut and align with the cutting groove 502. Then, the main hydraulic cylinder 42 is started to drive the knife holder 43 to drive the pressure cutting knife 44 through the cutting groove 502 until the channel steel on the pad 51 is cut. In this way, by using the cooperation of the pad 51 and the inner support block 53, when the side clamping block 31 clamps synchronously, the clamping strength at the cut of the channel steel is improved, thereby improving the overall cutting quality of the cut.

[0039] It is worth noting that both the side clamping hydraulic cylinder 3 and the main hydraulic cylinder 42 are externally connected to control oil circuits for controlling the side clamping and cutting. The specific control oil circuits and hydraulic control principles are existing technologies and will not be described in detail here.

[0040] The working principle of the hydraulic cutting tool provided by this utility model is as follows:

[0041] In use, the base plate 1 is installed on the conveyor line for cutting channel steel, and the channel steel is placed on the support frame 5 so that the cut is aligned with the chip discharge port 501. After alignment, the side clamping hydraulic cylinder 3 drives the side clamping block 31 to clamp the two sides of the channel steel. When clamping, the linkage plate 73 also moves closer to the channel steel. Under the meshing drive of the rack plate 74 and the gear 72, the rotating plate 71 moves away from the chip discharge port 501. Then the cutting assembly 4 is started to cut the channel steel. After cutting, when the side clamping hydraulic cylinder 3 drives the side clamping block 31 away from the channel steel, the linkage plate 73 also moves away from the channel steel. Similarly, under the meshing drive of the rack plate 74 and the gear 72, the rotating plate 71 rotates toward the chip discharge port 501, sweeping the chips on the support frame 5 out of the chip discharge port 501, thus completing the automatic chip removal.

[0042] Furthermore, when the support frame 5 carries the channel steel, one end of the channel steel passes over the support roller 55 on the U-shaped support frame 54 and then lies flat on the pad block 51. When the channel steel is inserted into the support frame 5, the inner support block 53 on the positioning plate 52 is inserted into the inside of the channel steel simultaneously to position and support both sides of the channel steel. When the channel steel moves, it is controlled to cut and align with the cutting groove 502. Then, the main hydraulic cylinder 42 is started to drive the knife holder 43 to drive the pressure cutting knife 44 through the cutting groove 502 until the channel steel on the pad block 51 is pressure cut. In this way, by using the cooperation of the pad block 51 and the inner support block 53, when the side clamping block 31 clamps synchronously, the clamping strength at the cut of the channel steel is improved, thereby improving the overall cutting quality of the cut.

[0043] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0044] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
