DETAILED DESCRIPTION

[0038] The following is combined with Figure 1-7 This application is described in further detail.

[0039] The embodiment of the present application discloses an angle steel cutting device.

[0040] Embodiment 1:

[0041] See also Figure 1 The angle steel cutting device comprises a workbench 1, a mounting shell 16 is fixedly connected to the top of the workbench 1, and a cutting cavity 17 is opened in the mounting shell 16, and the angle steel passes through the cutting cavity 17 during cutting.

[0042] See also Figure 1A support seat 11 with a rectangular top end face is fixedly connected to the top of the workbench 1. The support seat 11 is located in the cutting cavity 17. A placement groove 12 with a "V"-shaped structure adapted to the angle steel is provided on the top of the support seat 11. The extension direction of the placement groove 12 is parallel to the length direction of the support seat 11. A support frame 13 is movably provided on one side of the workbench 1. The support frame 13 is composed of a plurality of horizontal bars and vertical bars to form a frame structure. Rollers are fixedly connected to the four corners of the bottom of the support frame 13 to facilitate the adjustment of the position of the support frame 13. When in use, the uncut part of the angle steel is supported by the support frame 13.

[0043] See also Figure 1 and Figure 2 , an adjustment assembly 4 is provided on the side of the workbench 1 away from the support frame 13, which is used to adjust the cutting length of the angle steel. The adjustment assembly 4 includes an adjustment block 41 and an adjustment bolt 42. A slide rail 15 is fixedly connected to the side of the workbench 1 away from the support frame 13, and the position of the slide rail 15 is adapted to the position of the support seat 11. A slide groove 411 is provided at the bottom of the adjustment block 41, and the slide rail 15 slides in the slide groove 411, so that the adjustment block 41 can adjust the distance with the support seat 11 on the slide rail 15. The side walls on both sides of the slide groove 411 are fixedly connected to the limit blocks 412 respectively, and the bottom of the slide rail 15 slides on the top of the limit blocks 412, which can limit the adjustment block 41 and reduce the possibility of the adjustment block 41 detaching from the slide rail 15 in the vertical direction. The adjustment bolt 42 is threadedly connected to the top of the adjustment block 41. When in use, the adjustment bolt 42 is rotated until it is pressed against the slide rail 15, and the position of the adjustment block 41 is fixed at this time. Before cutting the angle steel, adjust the position of the adjusting block 41, and after adjustment, fix it with the adjusting bolt 42, and then slide the angle steel until it abuts against the adjusting block 41. At this time, the angle steel between the support seat 11 and the adjusting block 41 is the cut-off part, and the remaining part is the uncut part.

[0044] See also Figure 1 The workbench 1 is provided with a mounting seat 2 that slides up and down in the cutting cavity 17, and an upper cutting die 21 is fixedly connected to the bottom of the mounting seat 2. The upper cutting die 21 is located above the support seat 11 and away from the side of the support frame 13. When in use, the upper cutting die 21 is located directly above the angle steel, and then the upper cutting die 21 moves downward to cut the angle steel.

[0045] See also Figure 1 and Figure 2The support seat 11 is provided with a guide groove 111 extending in the vertical direction, the guide groove 111 is connected with the placement groove 12, and the upper cutting die 21 slides up and down in the guide groove 111 to guide the movement trajectory of the upper cutting die 21. Transmission holes 112 connected with the guide groove 111 are respectively provided on the opposite sides of the support seat 11, and the transmission holes 112 are located on both sides of the upper cutting die 21. The support seat 11 is fixedly connected with a transmission pipe 113, and the transmission pipe 113 is connected with the transmission hole 112. The transmission pipe 113 is threadedly connected with an oil storage cap 114 on the side away from the support seat 11, and an oil storage tank 115 is provided in the oil storage cap 114. The lubricating oil of the paste structure is stored in the oil storage tank 115. When in use, the oil storage cap 114 is rotated so that the oil storage cap 114 is close to the support seat 11. At this time, the lubricating oil in the oil storage tank 115 is pushed, which is conducive to the lubricating oil entering the slide groove 411 and lubricating the contact part between the slide groove 411 wall and the upper cutting die 21.

[0046] See also Figure 1 The mounting shell 16 is fixedly connected with a first hydraulic cylinder 22, and the piston rod end of the first hydraulic cylinder 22 is fixed to the top of the mounting seat 2. When in use, the first hydraulic cylinder 22 drives the mounting seat 2 to move up and down, driving the upper die 21 to move.

[0047] See also Figure 1 and Figure 2 The workbench 1 is provided with a connecting seat 3 that slides up and down in the cutting cavity 17. The connecting seat 3 is located on the side of the mounting seat 2 close to the support frame 13, and the connecting seat 3 is located directly above the support seat 11. The mounting shell 16 is fixedly connected to a second hydraulic cylinder 31, and the piston rod end of the second hydraulic cylinder 31 is fixed to the top of the connecting seat 3. When in use, the second hydraulic cylinder 31 drives the connecting seat 3 to move up and down.

[0048] See also Figure 1 , the first hydraulic cylinder 22 is fixedly connected with the first connecting pipe 23, the second hydraulic cylinder 31 is fixedly connected with the second connecting pipe 32, and the diameter of the first connecting pipe 23 is larger than the diameter of the second connecting pipe 32. The workbench 1 is fixedly connected with the hydraulic pipe 14, one side of the hydraulic pipe 14 is connected with the external hydraulic source, and the other side is simultaneously connected with the first connecting pipe 23 and the second connecting pipe 32. When in use, the hydraulic pipe 14 transmits hydraulic fluid. Since the diameter of the first connecting pipe 23 is larger than that of the second connecting pipe 32, the flow rate of the hydraulic fluid in the second connecting pipe 32 is greater than the flow rate of the hydraulic fluid in the first connecting pipe 23. At this time, the second hydraulic cylinder 31 first drives the connecting seat 3 to move downward, and the first hydraulic cylinder 22 then drives the mounting seat 2 to move downward, and the speed of the connecting seat 3 moving downward is greater than the speed of the mounting seat 2 moving downward.

[0049] See also Figure 1A pressing assembly 5 is provided at the bottom of the connecting seat 3. When in use, the pressing assembly 5 is used to press the uncut portion of the angle steel before the upper cutting die 21 cuts the angle steel. The pressing assembly 5 includes a pressing spring 51 and a pressing block 52. The pressing spring 51 is fixedly connected to the bottom of the connecting seat 3, and the pressing block 52 is fixedly connected to the bottom of the pressing spring 51. The side of the pressing block 52 away from the pressing spring 51 is adapted to the shape of the angle steel, thereby increasing the contact area between the pressing block 52 and the angle steel. When the second hydraulic cylinder 31 drives the connecting seat 3 to move downward, the pressing block 52 abuts against the angle steel, and then when the connecting seat 3 continues to move downward, the pressing spring 51 enters a compressed state, thereby increasing the strength of the pressing block 52 pressing the angle steel. When the upper cutting die 21 cuts the angle steel, the portion of the angle steel close to the support frame 13 is pressed by the pressing block 52, thereby reducing the possibility of warping and facilitating the flatness of the angle steel section.

[0050] See also Figure 1 and Figure 2 The workbench 1 is provided with a control component 6, which is used to simultaneously control the first hydraulic cylinder 22 and the second hydraulic cylinder 31 to start or pause. The control component 6 includes a starting pedal 61 and a travel switch 62. The starting pedal 61 is connected to the outer wall of the workbench 1 and placed on the ground. The starting pedal 61 is electrically connected to the first hydraulic cylinder 22 and the second hydraulic cylinder 31. When the starting pedal 61 is stepped on or released, the first hydraulic cylinder 22 and the second hydraulic cylinder 31 enter the starting state at the same time. A fixed column is fixedly connected to the top of the workbench 1, and the fixed column is located on one side of the vertical plane opposite to the length direction of the support seat 11. There are two travel switches 62, which are symmetrically fixed on the side of the fixed column facing the mounting seat 2. The travel switch 62 is electrically connected to the first hydraulic cylinder 22 and the second hydraulic cylinder 31. The mounting seat 2 is fixedly connected to a trigger rod 24, which extends between the upper and lower travel switches 62. When the trigger rod 24 touches the travel switch 62, the travel switch 62 sends a signal to the first hydraulic cylinder 22 and the second hydraulic cylinder 31, so that the first hydraulic cylinder 22 and the second hydraulic cylinder 31 are suspended. When in use, step on the starting pedal 61 to make the mounting seat 2 and the connecting seat 3 move downward, driving the upper cutting die 21 to cut the angle steel downward. When the angle steel is cut, the trigger rod 24 triggers the travel switch 62 located below. At this time, the first hydraulic cylinder 22 and the second hydraulic cylinder 31 are suspended. Then release the starting pedal 61, and the mounting seat 2 and the connecting seat 3 move upward until the trigger rod 24 triggers the travel switch 62 located above. At this time, the first hydraulic cylinder 22 and the second hydraulic cylinder 31 are suspended, and then the angle steel can be slid for the next cutting operation. In other embodiments, the travel switch 62 can also be a sensor or a limit switch.

[0051] The implementation principle of the angle steel cutting device in the first embodiment of the present application is as follows:

[0052] Before cutting the angle steel, first place the angle steel on the support frame 13 and the support seat 11, and adjust the position of the adjustment block 41 at the same time so that the length of the cut angle steel meets the requirements. When cutting the angle steel, first step on the start pedal 61 to start the first hydraulic cylinder 22 and the second hydraulic cylinder 31 at the same time, then the pressing block 52 first presses the uncut part of the angle steel, and then the upper cutting die 21 cuts the angle steel. At the same time, after the angle steel is cut, the trigger rod 24 triggers the travel switch 62 located below to pause the first hydraulic cylinder 22 and the second hydraulic cylinder 31. Then release the start pedal 61, so that the first hydraulic cylinder 22 and the second hydraulic cylinder 31 start to drive the pressing block 52 and the upper cutting die 21 to move to the position before cutting, until the trigger rod 24 triggers the travel switch 62 located above, the first hydraulic cylinder 22 and the second hydraulic are paused, and then the angle steel can be slid for the next round of cutting.

[0053] Embodiment 2:

[0054] The difference between the second embodiment and the first embodiment is that: Figure 3 The pressing assembly 5 includes a pressing rod 53 and a mounting rod 54 . The mounting rod 54 is fixedly connected to the bottom of the connecting seat 3 , and the mounting rod 54 is located directly above the placement groove 12 .

[0055] See also Figure 4 and Figure 5 The bottom of the mounting rod 54 is provided with a mounting groove 541 extending upward, the pressing rod 53 slides up and down in the mounting groove 541, a guide block is fixed on the outer peripheral side of the pressing rod 53, and a sliding groove is provided in the groove wall of the mounting groove 541, and the guide block slides up and down in the sliding groove, thereby reducing the possibility of the pressing rod 53 escaping from the mounting groove 541. The mounting rod 54 is rotatably connected with a rotating shaft 55, the rotating shaft 55 passes through the mounting groove 541 and both ends extend outside the mounting rod 54, and both ends of the rotating shaft 55 are respectively fixedly connected with abutting columns 551, and the abutting columns 551 can be flipped toward or away from the angle steel. The outer peripheral side of the rotating shaft 55 is rotatably connected with a gear 552, and there is a certain friction force between the gear 552 and the rotating shaft 55. The outer peripheral side of the pressing rod 53 is fixedly connected with a rack 531, and the rack 531 is meshed with the gear 552. When the pressing rod 53 slides into the mounting groove 541, the rack 531 drives the gear 552, so that the rotating shaft 55 enters a rotating state. At this time, the abutting column 551 turns toward the angle steel until it abuts against the angle steel. When the abutting column 551 abuts against the angle steel, the gear 552 and the rotating shaft 55 enter an idling state.

[0056] See also Figure 6 and Figure 7The installation groove 541 is connected to the groove wall on the side away from the upper cutting die 21 and is provided with a moving groove. The installation rod 54 is provided with a connecting plate 542. The connecting plate 542 slides in the moving groove along the extending direction of the angle steel. The connecting plate 542 is fixedly connected to the side facing the upper cutting die 21 with a supporting tooth 543. The outer peripheral side of the rotating shaft 55 is fixedly connected with a sliding tooth 553 along the circumferential direction, and the sliding tooth 553 can mesh with the supporting tooth 543. When the sliding tooth 553 is meshed with the supporting tooth 543, the pressing rod 53 slides into the mounting groove 541. At this time, the rotating shaft 55 drives the sliding tooth 553 to slide unidirectionally on the supporting tooth 543. When the pressing rod 53 slides out of the mounting groove 541, the supporting tooth 543 unidirectionally supports the sliding tooth 553. Similarly, when the clamping column 551 is pressed against the angle steel, if the angle steel is warped upward, the supporting tooth 543 unidirectionally supports the sliding tooth 553, thereby preventing the rotating shaft 55 from rotating in the opposite direction, which is beneficial for the clamping column 551 to maintain the state of being pressed against the angle steel.

[0057] See also Figure 5 and Figure 7 The connecting seat 3 is provided with a driving assembly 7. When the pressing rod 53 slides into the installation groove 541, the driving assembly 7 drives the connecting plate 542 to slide until the supporting tooth 543 is engaged with the sliding tooth 553. When the pressing rod 53 is away from the angle steel, the driving assembly 7 drives the connecting plate 542 to slide until the supporting tooth 543 is away from the sliding tooth 553.

[0058] See also Figure 5 and Figure 7 The driving assembly 7 includes a driving column 71, a driving sleeve 72 and a driving spring 73. The driving sleeve 72 is fixed at the bottom of the connecting seat 3 near the support frame 13 (the support frame 13 is Figure 3 On the side marked in the middle, the driving column 71 slides up and down on the driving sleeve 72. A limiting block is fixed on the outer peripheral side of the driving column 71, and a limiting groove is opened on the inner wall of the driving sleeve 72. The limiting block slides up and down in the limiting groove to reduce the possibility of the driving column 71 detaching from the driving sleeve 72. A power spring 721 is installed in the driving sleeve 72, one end of the power spring 721 abuts against the top of the driving column 71, and the other end abuts against the connecting seat 3. When in use, the power spring 721 pushes the driving column 71 to slide out of the driving sleeve 72. When the connecting seat 3 slides downward, the driving column 71 abuts against the angle steel before the pressing rod 53.

[0059] See also Figure 5 and Figure 7The mounting rod 54 is slidably penetrated with a connecting rod 544, which is fixed on the side of the connecting plate 542 facing away from the supporting teeth 543. The outer wall of the driving sleeve 72 is provided with a connecting hole 722, through which the connecting rod 544 passes. A stopper 545 is fixedly connected to the outer peripheral side of the connecting rod 544, and the stopper 545 is located between the mounting rod 54 and the driving sleeve 72. The driving spring 73 is sleeved on the outer peripheral side of the connecting rod 544, and one end of the driving spring 73 abuts against the side of the stopper 545 facing the mounting rod 54, and the other end abuts against the outer peripheral side of the mounting rod 54. When in use, the driving spring 73 is elastically released to push the connecting rod 544 to abut against the outer peripheral side of the driving column 71.

[0060] See also Figure 5 and Figure 7 A slot 711 is provided on the outer circumference of the driving column 71. When the connecting rod 544 is aligned with the slot 711, the driving spring 73 pushes the connecting rod 544 into the slot 711, and the supporting tooth 543 is away from the sliding tooth 553. The mounting rod 54 is provided with an elastic pusher, which is a pusher spring 8. The pusher spring 8 is installed in the mounting groove 541. One end of the pusher spring 8 abuts against the top of the pressing rod 53, and the other end abuts against the groove wall of the mounting groove 541. When the supporting tooth 543 is away from the sliding tooth 553, the pusher spring 8 pushes the pressing rod 53 to slide out of the mounting groove 541. A driving surface 5441 is inclined on one side of the connecting rod 544 away from the connecting plate 542. After the driving column 71 abuts against the angle steel, the connecting seat 3 continues to move downward, the driving column 71 slides into the driving sleeve 72, and the groove wall of the slot 711 slides on the driving surface 5441, pushing the connecting rod 544 out of the slot 711, so that the connecting rod 544 slides in contact with the outer peripheral side of the driving column 71, and at this time the supporting teeth 543 are meshed with the sliding teeth 553.

[0061] The implementation principle of the angle steel cutting device of the second embodiment of the present application is as follows: when in use, the connecting seat 3 slides downward, at which time the driving column 71 first abuts against the angle steel, and when the connecting seat 3 continues to slide downward, the driving column 71 pushes the connecting rod 544, so that the supporting teeth 543 are meshed with the sliding teeth 553. Then the pressing rod 53 abuts against the angle steel, driving the rotating shaft 55 to rotate, so that the abutting column 551 flips to abut against the angle steel, and when the angle steel is warped, the abutting column 551 restricts the angle steel, which is conducive to maintaining the state of the angle steel. When the connecting seat 3 moves upward, the power spring 721 pushes the driving column 71 to slide out of the driving sleeve 72, and when the connecting rod 544 is aligned with the card slot 711, the driving spring 73 pushes the connecting rod 544 to slide into the card slot 711, and at this time the supporting teeth 543 are away from the sliding teeth 553, and the pushing spring 8 is elastically released, pushing the pressing rod 53 to slide out of the installation slot 541.

[0062] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
