Technical Field

[0001] The present invention relates to the technical field of steel plate cutting devices, and particularly relates to a cutting device for steel formwork processing. Background Art

[0002] During the construction process, a large number of steel formworks are required. For different usage positions, steel formworks of different shapes or sizes may be needed. To meet the usage requirements, the steel formworks need to be cut.

[0003] Chinese Patent CN220698426U discloses a cutting device for die steel production. By driving two clamping blocks to move towards the center until the two anti-sliding blocks fix the die steel, and then cutting, it can avoid the offset of the die steel during the cutting process, and the operation is convenient and fast.

[0004] The above device cuts the plate by a cutting blade, and the cut plate stays on the workbench. During the stacking process, workers need to remove the cut plate from the workbench. On the one hand, the operation is not convenient enough, and on the other hand, it will also affect the overall progress of the cutting operation. In summary, there is still room for improvement in the above device.

[0005] Therefore, it is necessary to provide a cutting device for steel formwork processing to solve the above technical problems. Summary of the Invention

[0006] The purpose of the present invention is to provide a cutting device for steel formwork processing to solve the problem that in the existing device, the plate is cut by a cutting blade, and the cut plate stays on the workbench. During the stacking process, workers need to remove the cut plate from the workbench, making the operation not convenient enough as mentioned in the above background art.

[0007] Based on the above idea, the present invention provides the following technical solution: A cutting device for steel formwork processing, including a bottom plate. Fixed seats and sliding seats are respectively installed at both ends of the bottom plate. Rotating shafts are rotatably installed in both the fixed seats and the sliding seats. A top plate is installed on the outer peripheral wall of the rotating shaft. A bracket for placing the plate is provided on the side of the fixed seat away from the sliding seat. A cutting head is provided above the fixed seat. A plurality of cushion blocks are slidably assembled at the front and rear positions inside the top plate, and notch openings for guiding out the cushion blocks are provided on the front and rear side surfaces of the top plate;

[0008] Inside the top plate, an extrusion assembly is provided on one side of the cushion block. Slots are formed in the inner walls of both the sliding seat and the fixed seat. When the top plate rotates to the vertical state and is parallel to the slots, the extrusion assembly can push the cushion block at the top out through the notch and insert it into the slots. After the cushion block is separated from the top plate, the cushion block can slide downward along the slots. As the top plate deflects downward and leaves the plate member, the plate member can fall onto the cushion block.

[0009] As a further solution of the present invention: The extrusion assembly includes a top rod provided on one side of the cushion block. The top rod is integrally L-shaped. A storage groove for storing a plurality of cushion blocks is formed on the top plate. A limiting spring is installed at the bottom end of the storage groove. The top rod is located at the top end position of the storage groove. A counterweight is provided below the top rod, and a pull rope is fixedly arranged between the counterweight and the top rod.

[0010] As a further solution of the present invention: An arc-shaped groove is formed on one side of the cushion block close to the top rod, and both ends of the arc-shaped groove extend to the end faces of both ends of the cushion block.

[0011] As a further solution of the present invention: Straight grooves and inclined grooves are formed on both inner side walls of the slots. The straight grooves are distributed at both ends of the inclined grooves and are connected to the inclined grooves. Limiting blocks are elastically connected to both side faces of the cushion block. When the cushion block is pushed by the top rod and inserted into the slots, the limiting blocks can be inserted into the straight grooves.

[0012] As a further solution of the present invention: Protrusions are fixedly installed on both the front and rear sides of the top plate. Magnets are slidably arranged in the protrusions. A positioning block is elastically connected to the top wall of the storage groove. A traction rope is fixedly arranged between the magnet and the positioning block. A positioning groove is formed on the top surface of the cushion block. Magnetic blocks are fixedly embedded on the inner walls of both the sliding seat and the fixed seat. The surfaces of the magnetic blocks opposite to the magnets have different magnetic poles.

[0013] As a further solution of the present invention: A support frame is provided on the outside of the fixed seat, and the cutting head is located below the support frame.

[0014] As a further solution of the present invention: A horizontal support portion is provided on the bracket.

[0015] As a further solution of the present invention: Both the fixed seat and the sliding seat are U-shaped.

[0016] As a further solution of the present invention: The fixed seat is fixedly connected to the bottom plate, and the sliding seat can slide along the length direction of the bottom plate.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: When the top plate deflects downward from the vertical state, the counterweight will reset, thereby causing the ejector rod to reset. The pressure of the limiting spring can drive the remaining pads to move upward, so that the topmost pad is at the notch for the next use. Repeating the above process, as the top plate rotates, multiple pads can be stacked in sequence, making the height of the plate members stacked on the supporting part the same as the height of the pads stacked in the slot. The remaining plate members can then fall above the plate members stacked on the supporting part and the pads stacked in the slot and remain in a horizontal state, which is beneficial for the cutting of the cutting head.

Detailed implementation manner

[0030] As Figures 1-10 shown, a cutting device for steel formwork processing includes a bottom plate 1. At positions near both ends on the top of the bottom plate 1, a fixed seat 3 and a sliding seat 2 are respectively installed. Specifically, the fixed seat 3 is fixedly connected to the bottom plate 1, while the sliding seat 2 can slide along the length direction of the bottom plate 1. Both the fixed seat 3 and the sliding seat 2 are integrally arranged in a U shape, and a rotating shaft 10 is rotatably installed inside both the fixed seat 3 and the sliding seat 2. A top plate 11 is fixedly connected to the outer peripheral wall of the rotating shaft 10 through bolts. Specifically, the top plate 11 is detachably connected to the rotating shaft 10. Referring to Figures 1-2 、 Figure 4 shown, a bracket 4 for placing the plate member 7 is provided on the side of the fixed seat 3 away from the sliding seat 2, and a horizontal supporting part 401 is provided on the bracket 4. During actual use, the plate member 7 to be cut is placed on the two top plates 11. When the two rotating shafts 10 rotate and drive the top plates 11 to rotate, the plate member 7 can be driven to move obliquely upward through the cooperation of the two top plates 11. When the top plate 11 deflects downward, one end of the plate member 7 can gradually fall onto the supporting part 401. A cutting head 6 for cutting the plate member 7 is provided above the fixed seat 3. After the plate member 7 is cut by the cutting head 6, the cut plate member 7 can be placed on the supporting part 401. Then, as the top plate 11 rotates, the remaining plate member 7 can be jacked upward, so that the remaining plate member 7 moves obliquely upward and finally falls onto the cut plate member 7, so that the cut plate member 7 can be stacked on the supporting part 401.

[0031] As Figures 1-10As shown, a plurality of cushion blocks 15 are slidably assembled inside the top plate 11 at positions on the front and rear sides. The plurality of cushion blocks 15 are distributed radially along the rotating shaft 10. Notches 22 for guiding out the cushion blocks 15 are formed on both the front and rear side surfaces of the top plate 11. An extrusion assembly is arranged inside the top plate 11 on one side of the cushion blocks 15. Vertical slots 8 are formed on both inner side walls of the sliding seat 2 and both inner side walls of the fixed seat 3. During actual use, as the top plate 11 gradually rotates upward, the extrusion assembly can apply pressure to the topmost cushion block 15, causing the topmost cushion block 15 to tend to be guided out through the notch 22. When the top plate 11 rotates upward to a vertical state, the cushion block 15 can be inserted into the slot 8 and slide downward to the bottom position of the slot 8. Subsequently, as the top plate 11 deflects downward and leaves the plate member 7, the plate member 7 can fall onto the cushion block 15, thereby raising the height of the plate member 7 to be cut, so that one end of the plate member 7 to be cut can fall above the plurality of plate members 7 stacked on the support portion 401.

[0032] The extrusion assembly includes a ejector rod 14 arranged on one side of the cushion block 15. The ejector rod 14 is integrally L-shaped. Storage grooves for storing a plurality of cushion blocks 15 are formed at both side positions of the top plate 11. A limiting spring is installed at the bottom end of the storage groove. Through this structure, it can be ensured that the topmost cushion block 15 is at the notch 22, while the ejector rod 14 is at the top end position of the storage groove, so that the ejector rod 14 is always aligned with the topmost cushion block 15. The storage groove communicates with the above-mentioned notch 22;

[0033] Further, a counterweight 13 is arranged below the ejector rod 14. The counterweight 13 is slidably matched with the top plate 11, and a pull rope 16 is fixedly arranged between the counterweight 13 and the vertical section of the ejector rod 14. The pull rope 16 passes through the top plate 11 and is slidably matched with it. When the top plate 11 rotates to near the slot 8 but is not parallel to the slot 8, the top plate 11 is approximately in a vertical state, so that the counterweight 13 can pull the ejector rod 14 through the pull rope 16, and the topmost cushion block 15 can be pushed out through the ejector rod 14.

[0034] For the stable cooperation between the ejector rod 14 and the cushion block 15, an arc-shaped groove 1502 is formed on one side of the cushion block 15 close to the ejector rod 14. Both ends of the arc-shaped groove 1502 extend to the end faces at both ends of the cushion block 15.

[0035] To avoid interference between the top plate 11 and the cushion block 15 in the slot 8 during rotation, straight grooves 801 and inclined grooves 802 are formed on both the left and right side walls inside the slot 8. Refer to Figures 5-6As shown, straight grooves 801 are distributed at both ends of the inclined groove 802 and the straight grooves 801 communicate with the inclined groove 802. Elastic limiting blocks 1503 are connected to both side surfaces of the spacer block 15. When the spacer block 15 is pushed by the ejector rod 14 and inserted into the slot 8, the limiting block 1503 can be inserted into the straight groove 801. When the spacer block 15 slides down along the slot 8, the limiting block 1503 can slide down from the straight groove 801 to the inclined groove 802. During this process, the spacer block 15 will move in a direction away from the top plate 11, thereby avoiding interference between the top plate 11 and the spacer block 15 in the slot 8. Since the distance from the end face of the end of the spacer block 15 away from the top plate 11 to the inner wall of the slot 8 is small, the spacer block 15 will not turn over when sliding down along the slot 8.

[0036] In actual use, the plate 7 to be cut is placed on the two top plates 11, and one end of the plate 7 is on the supporting part 401. The plate 7 is cut by the cutting head 6, and the cut plate 7 remains on the supporting part 401. Then, the top plate 11 is driven to rotate by the rotating shaft 10. During the rotation of the top plate 11, the remaining plate 7 can be driven to move obliquely upward, so that one end of the remaining plate 7 can abut against the vertical section of the bracket 4. The bracket 4 can prevent the remaining plate 7 from continuing to move in the horizontal direction. When the top plate 11 rotates to near the slot 8, as described above, the counterweight 13 can pull the ejector rod 14 through the pull rope 16, so that one end of the ejector rod 14 is inserted into the arc-shaped groove 1502 of the cushion block 15. The topmost cushion block 15 can be pushed out through the notch 22 by using the ejector rod 14. When the top plate 11 rotates upward to the vertical state, the cushion block 15 can be aligned with the slot 8. At this time, the ejector rod 14 will push the topmost cushion block 15 into the slot 8. As the cushion block 15 is inserted into the slot 8, the limit block 1503 on the cushion block 15 will be aligned with the straight groove 801 and can be inserted into the straight groove 801. When the cushion block 15 is in the state of being pushed out from the notch 22 and inserted into the slot 8, the center of the arc-shaped groove 1502 on this cushion block 15 is collinear with the axis of the rotating shaft 10. Therefore, when the rotating shaft 10 continues to drive the top plate 11 and the ejector rod 14 on the top plate 11 to rotate, one end of the ejector rod 14 can be led out through the arc-shaped groove 1502. As the ejector rod 14 separates from the cushion block 15, the cushion block 15 in the slot 8 can move downward along the slot 8. Through the cooperation of the inclined groove 802 and the limit block 1503, the cushion block 15 can move away from the top plate 11 during the downward sliding process, thereby avoiding interference between the top plate 11 and the cushion block 15 in the slot 8 during subsequent rotation. In actual operation, the thickness of the cushion block 15 is the same as that of the plate 7. When the top plate 11 deflects downward from the vertical direction, the remaining plate 7 can move downward and finally fall onto the stacked plates 7 on the supporting part 401 and the top of the cushion block 15 in the slot 8. The stacked plates 7 on the supporting part 401 and the cushion block 15 in the slot 8 can stably support the remaining plate 7, which is beneficial for the cutting head 6 to continue cutting the remaining plate 7;

[0037] When the top plate 11 is deflected downward from the vertical state, the counterweight 13 will be reset, thereby resetting the top rod 14, and the pressure of the limit spring can drive the remaining pads 15 to move upward, so that the topmost pad 15 is in the slot 22, so as to facilitate the next use. The above process is repeated. As the top plate 11 rotates, multiple pads 15 can be stacked in sequence, so that the height of the panels 7 stacked on the support part 401 is the same as the height of the pads 15 stacked in the slot 8, and the remaining panels 7 can fall above the panels 7 stacked on the support part 401 and the pads 15 stacked in the slot 8 and remain in a horizontal state, which is beneficial to the cutting of the cutting head 6. After the cutting is completed, the panels 7 stacked on the support part 401 can be removed by a forklift or other equipment.

[0038] In summary, this device can push the plate 7 through the rotation of the top plate 11, which is beneficial for the cutting head 6 to continuously cut the plate 7, and the cut plates 7 can be stacked on the support part 401, which is beneficial for the storage of the plates 7.

[0039] like Figures 1-10 As shown, the front and rear sides of the top plate 11 are fixedly installed with protrusions 12, and the protrusions 12 are located on the side of the top plate 11 away from the rotating shaft 10. A magnet 18 is slidably arranged in the protrusion 12, and a positioning block 19 is elastically connected to the top wall of the storage slot. A traction rope 17 is fixedly arranged between the magnet 18 and the positioning block 19, and the traction rope 17 passes through the protrusion 12 and the top plate 11 and slidably cooperates with the two. A positioning groove 1501 is opened on the top surface of the cushion block 15. When the top cushion block 15 is moved upward to the notch 22 by the pressure of the limit spring, the positioning block 19 can be inserted into the positioning groove 1501 of the top cushion block 15, so as to limit the top cushion block 15, combined with Figure 1 As shown, a magnetic block 9 is fixedly embedded on the inner wall of the sliding seat 2 and the fixed seat 3, and the side of the magnetic block 9 opposite to the magnet 18 has different magnetic poles. Through this structure, when the top plate 11 rotates to the vicinity of the slot 8, the magnet 18 on the protrusion 12 can be aligned with the magnetic block 9, and the traction rope 17 can be pulled by the suction force between the two, thereby pulling the positioning block 19 through the traction rope 17, so that the positioning block 19 is separated from the positioning groove 1501. At this point, the topmost cushion block 15 can be pushed out through the slot 22 through the top rod 14. The purpose of this setting is: only when the top plate 11 rotates to the vicinity of the slot 8, the cushion block 15 can be guided out through the slot 22, which can effectively avoid the problem of the cushion block 15 interfering with the fixed seat 3 or the sliding seat 2 when the top plate 11 rotates.

[0040] like Figures 1-10As shown in the figure, in order to drive the sliding seat 2 to move, a driving motor is provided on the side of the sliding seat 2 away from the fixed seat 3. The driving motor is installed on the bottom plate 1, and the output shaft of the driving motor is drivingly connected to a screw rod 21. The screw rod 21 passes through the sliding seat 2 and is threadedly connected thereto, and one end of the screw rod 21 passing through the sliding seat 2 is rotatably engaged with the fixed seat 3, so as to drive the sliding seat 2 to move on the bottom plate 1. Of course, this is only one way to drive the sliding seat 2 to slide. Since the structure for driving the sliding seat 2 to slide is a mature technical means in the mechanical field, other ways to drive the sliding seat 2 to slide will not be elaborated. Of course, a slide rail that slidably cooperates with the sliding seat 2 can be installed on the bottom plate 1 to improve the stability of the movement of the sliding seat 2.

[0041] A support frame 5 is provided outside the fixed seat 3, and the cutting head 6 is located below the support frame 5. Specifically, a hydraulic rod can be assembled on the support frame 5, and the telescopic end of the hydraulic rod is connected to the cutting head 6, so as to drive the cutting head 6 to move in the vertical direction. And the hydraulic rod can slide on the support frame 5. Specifically, the hydraulic rod can be driven to move relative to the support frame 5 by means of a lead screw slider structure or a hydraulic drive. Of course, the above-mentioned cutting head 6 can cut the plate member 7 by means of laser cutting.

[0042] In order to drive the rotation of the rotating shaft 10, a connecting shaft is fixedly installed at the end of the rotating shaft 10 in this solution. Specifically, the end of the rotating shaft 10 at the fixed seat 3 passes through the fixed seat 3 and is rotatably engaged therewith, while the end of the rotating shaft 10 at the sliding seat 2 passes through the sliding seat 2 and is rotatably engaged therewith. Motors are installed on both the fixed seat 3 and the sliding seat 2, and the output shaft of the motor and the connecting shaft can be drivingly cooperated through a transmission unit such as a belt or a chain, so as to drive the rotation of the rotating shaft 10. Since the structure for driving the rotation of the rotating shaft 10 is relatively common, relevant structures are not marked in the drawings.

[0043] As Figures 3-10 shown, an installation groove 1101 is opened on the top plate 11 on one side of the storage tank. The ejector rod 14 slides in the installation groove 1101. The installation groove 1101 is set to be L-shaped. Combining Figure 6 shown, a first spring is provided between the vertical section of the ejector rod 14 and the end face of the installation groove 1101. When the counterweight 13 pulls the ejector rod 14 through the pull rope 16, the ejector rod 14 can compress the first spring.

[0044] A rectangular groove for installing the counterweight 13 is opened on the top plate 11, so that the counterweight 13 slides in the rectangular groove.

[0045] One side of the storage tank can be an open structure and is sealed by a sealing plate 23. The sealing plate 23 can be fixed to the top plate 11 by bolts. With this structure, it is beneficial to take and store the cushion block 15.

[0046] One end face of the bump 12 away from the top plate 11 is provided with a chute that slidably cooperates with the magnet 18, and a groove that slidably cooperates with the positioning block 19 is provided at the top wall of the storage groove. A second spring is fixedly arranged between the inner end face of the groove and the positioning block 19.

[0047] Combined Figure 9 As shown, clamping units 20 can be installed at positions on both sides of the fixed seat 3. The clamping units 20 can be cylinders. The telescopic ends of the cylinders are fixedly connected with pressing plates 2001. The plate member 7 can be clamped through the pressing plates 2001, improving the stability of the plate member 7 during cutting.

[0048] Combined Figure 10 As shown, a guiding groove that slidably cooperates with the limiting block 1503 is provided at the end face of the cushion block 15. A spring is fixedly arranged between the inner end face of the guiding groove and the limiting block 1503.
