Description

Technical Field

[0001] The utility model relates to the technical field of tipping machines, in particular to a hydraulic tipping machine for steel plates. Background Art

[0002] Steel plate products have strict standards and requirements for the quality of their upper and lower surfaces. Therefore, before the steel plates are stored in the warehouse, the upper and lower surfaces must be visually inspected manually. Therefore, it is necessary to turn over the steel plates, and tipping machines are mostly used for turning over the steel plates.

[0003] After retrieval, the prior art discloses a large-format steel plate hydraulic tipping machine (publication number: CN111646170A), which includes a frame. Along the length direction of the frame, a plurality of tipping mechanisms are provided. The tipping mechanism includes a bracket connected to the frame. On both sides of the bracket along its width direction, a first tipping component and a second tipping component are respectively provided. Both the first tipping component and the second tipping component include tipping arms for carrying the steel plate. One end of the tipping arm close to the bracket is rotatably connected to the bracket through a first connection support. On the side of the tipping arm far from the steel plate, a driving member for assisting the lifting of the steel plate is provided. On the end face of the tipping arm close to the steel plate, a gas flow channel component and an anti-collision component are provided. The gas flow channel component includes a gas groove opened on the end face of the tipping arm, and the gas groove is connected to an external vacuum pump through an air pipe.

[0004] In the prior art, the turning over of the plate is realized by clamping the plate with two turnable tipping plates. When the steel plate falls on the tipping plate, a strong rigid impact will be generated, which is an adverse factor for the surface protection of the plate, and at the same time, a large amount of noise will be generated. In the prior art, the impact is slowed down by air flow, and correspondingly, an air source and a control component need to be set up, and its structure is relatively complex and the maintenance cost is relatively high.

[0005] Therefore, we propose a hydraulic tipping machine for steel plates. Summary of the Utility Model

[0009] A buffer structure is provided on one side of the tipping plate body for limiting and buffering workpieces. The buffer structure includes a mounting seat, a pressing block, and an outer cylinder. The mounting seat is detachably connected to the tipping plate body. The pressing block is fixedly connected to the mounting seat. The outer cylinder is movably arranged on one side of the pressing block. The outer cylinder has a plurality of deformable petal-like structures, and the workpiece can push the outer cylinder closer to the pressing block to deform the petal-like structures.

[0010] As a preferred embodiment of the present invention, the ear plate forms a rectangular plate. The ear plate is fixedly installed at a position near the bottom of the tipping plate body. A plurality of ear plates are equidistantly arranged on one side of the tipping plate body, and a gap is left between adjacent two ear plates for the ear plate on one side of another tipping plate body to be inserted.

[0011] As a preferred embodiment of the present invention, the mounting seat forms a rectangular block. Mounting holes are provided at the four corner positions of the mounting seat. The mounting seat is locked and fixed to the tipping plate body by screws.

[0012] As a preferred embodiment of the present invention, the pressing block forms a frustum structure. The outer cylinder is cylindrical. The inner diameter of the outer cylinder is smaller than the diameter of the smaller end of the pressing block. The larger end of the pressing block is fixedly connected to the mounting seat.

[0013] As a preferred embodiment of the present invention, the buffer structure further includes deformation grooves. A plurality of deformation grooves are provided at the end of the outer cylinder. The outer cylinder forms petal-like structures through the deformation grooves.

[0017] Beneficial effects

[0018] The present invention provides a hydraulic tipping machine for steel plates. It has the following beneficial effects:

[0019] 1. This hydraulic plate flipping machine for steel plates, by means of a deformable outer cylinder close to a truncated cone-shaped extrusion block, utilizes the circumferential surface of the extrusion block to push the petal-shaped structure of the outer cylinder to expand and deform to absorb impact, thereby weakening the rigid impact of the steel plate, protecting the surface of the plate, and suppressing the large-distance displacement of the plate. At the same time, it also provides support and cushioning for the steel plate to interchange positions between the two flap bodies. It has a simple structure, low use and maintenance costs, and can reduce noise from the source of use while reducing noise generated by impact.

[0020] 2. This hydraulic plate turning machine for steel plates is provided with deformation grooves, which are used to form several petal-like structures at the end of the outer cylinder. When the plate is squeezed against the end of the outer cylinder, the end of the outer cylinder with the deformation groove can be close to the extrusion block, and the petal-like structure between two adjacent deformation grooves is deformed by the extrusion block, thereby absorbing and buffering rigid impact, thereby achieving the purpose of protection and buffering.

[0021] 3. The hydraulic plate turning machine for steel plates is provided with a limit block which can be made of rubber. When the outer cylinder is close to the extrusion block, the end of the limit block can contact the end of the extrusion block, thereby realizing another buffering and protection.

[0022] 4. This hydraulic flap machine for steel plates, by setting a shock absorber assembly and a retaining ring, the shock absorber assembly can adopt known public technology, and the specific model is not restricted too much here. By setting the shock absorber assembly and the retaining ring, the retaining ring is used to limit the output shaft of the shock absorber assembly to prevent the shock absorber assembly from being completely separated from the extrusion block. When the outer cylinder is close to the extrusion block, the output shaft of the shock absorber assembly can be pushed by the mounting seat, and another buffering effect is achieved by the displacement of the output shaft of the shock absorber assembly. In conjunction with the above-mentioned limit block and outer cylinder, the rigid impact of the steel plate on the flap body can be greatly reduced.

[0023] 5. This hydraulic flip machine for steel plates uses a push cylinder to push the flip body to flip, and the two flip bodies are close to each other. The flip bodies are provided with several avoidance grooves. The flap bodies form a comb tooth structure through the avoidance grooves for misalignment of the two flap bodies when they are close to each other. When the plate is dumped from one of the flap bodies to the other, the push cylinder is controlled to restore the two flap bodies to the level, thereby realizing the flipping of the steel plate. The structure is simple and practical. By arranging several ear plates on one side of each flap body, when the flap body is gradually flipped from horizontal to vertical, the edge position of the plate is lifted by the ear plates, thereby ensuring the stability of the plate during the flipping movement of the flap body.

[0031] A hydraulic flap machine for steel plates, as Figure 1 and Figure 2 shown, includes:

[0032] A base 10, on the top of the base 10, two flap bodies 11 are rotatably connected. On one side of each flap body 11, a number of push cylinders 12 for pushing the flap body 11 to flip are arranged. On the side walls of the two flap bodies 11 close to each other, a number of ear plates 13 for bearing are fixedly installed. The ear plates 13 on the side walls of the two flap bodies 11 are staggeredly distributed. The ear plates 13 form a rectangular plate. The ear plates 13 are fixedly installed at a position close to the bottom of the flap body 11. A number of ear plates 13 are equidistantly arranged on one side of the flap body 11. A gap is left between two adjacent ear plates 13 for the ear plates 13 on one side of the other flap body 11 to insert;

[0033] In this solution, the flap body 11 is mainly pushed to flip by the push cylinder 12. In the initial position, the two flap bodies 11 are in a horizontal state. The steel plate is placed on the horizontal flap body 11 through a hoisting device, and the hoisting device can be a crane. The push cylinder 12 is used to push the flap body 11 to flip. The two flap bodies 11 approach each other. The flap body 11 is provided with several avoidance grooves. The flap body 11 forms a comb structure through the avoidance grooves for staggering when the two flap bodies 11 approach each other. When the plate is poured from one flap body 11 to the other flap body 11, the push cylinder 12 is controlled to make the two flap bodies 11 return to the horizontal, realizing the flipping of the steel plate. The structure is simple and practical. By arranging several ear plates 13 on one side of each flap body 11, when the flap body 11 gradually flips from horizontal to vertical, the edge position of the plate is lifted by the ear plates 13, which can ensure the stability of the plate during the flipping movement of the flap body 11.

[0034] As Figure 3 、Figure 4 and Figure 5 As shown in Figure 5 , a buffer structure is provided on one side of the flap body 11 for limiting and buffering workpieces. The buffer structure includes a mounting base 20, a pressing block 21, and an outer cylinder 22. The mounting base 20 is detachably connected to the flap body 11. The pressing block 21 is fixedly connected to the mounting base 20. The outer cylinder 22 is movably arranged on one side of the pressing block 21. The outer cylinder 22 has a number of deformable petal-like structures. The workpiece can push the outer cylinder 22 closer to the pressing block 21 to cause the petal-like structures to deform. The mounting base 20 forms a rectangular block, and mounting holes are provided at the four corners of the mounting base 20. The mounting base 20 is locked and fixed to the flap body 11 by screws. The pressing block 21 forms a frustum structure. The outer cylinder 22 is cylindrical. The inner diameter of the outer cylinder 22 is smaller than the diameter of the smaller end of the pressing block 21. The larger end of the pressing block 21 is fixedly connected to the mounting base 20;

[0035] In this solution, considering that when the sheet is placed on the horizontal flap body 11 of the flap body 11, the rigid impact during the fall of the sheet is relatively strong. By moving the deformable outer cylinder 22 closer to the frustum-shaped pressing block 21, the circumferential surface of the pressing block 21 is used to squeeze and push the petal-like structure of the outer cylinder 22 to expand and deform to absorb the impact, weaken the rigid impact of the steel plate, protect the surface of the sheet, and inhibit the large-distance offset of the sheet. At the same time, it also provides support and buffering for the steel plate to exchange positions between the two flap bodies 11.

[0036] As Figure 5 shown in Figure 5 , the buffer structure further includes a deformation groove 23. A number of deformation grooves 23 are provided at the end of the outer cylinder 22. The outer cylinder 22 forms a petal-like structure through the deformation grooves 23. The deformation groove 23 is a rectangular groove. The depth of the deformation groove 23 is smaller than the length of the outer cylinder 22. A number of deformation grooves 23 are arranged in an annular array at the end of the outer cylinder 22. By providing the deformation grooves 23, the end of the outer cylinder 22 forms a number of petal-like structures through the deformation grooves 23. When the sheet presses the end of the outer cylinder 22, the end of the outer cylinder 22 provided with the deformation grooves 23 can be close to the pressing block 21. The petal-like structure between two adjacent deformation grooves 23 is deformed by the pressing block 21 to absorb and buffer the rigid impact, achieving the purpose of protection and buffering.

[0037] As Figure 6 shown in Figure 6 , the buffer structure further includes a limiting block 24. The limiting block 24 is fixedly connected to the outer cylinder 22. The limiting block 24 can abut against the end of the pressing block 21. By providing the limiting block 24, the limiting block 24 can be made of rubber material. When the outer cylinder 22 approaches the pressing block 21, the end of the limiting block 24 can abut against the end of the pressing block 21 to achieve another type of buffering and protection.

[0038] As Figure 5 and Figure 6As shown, the buffer structure further includes a shock absorber assembly 25 and a retaining ring 26. The retaining ring 26 is fixedly connected to the outer cylinder 22. A round hole is provided at the center position of the limit block 24. The shock absorber assembly 25 passes through the round hole and is connected to the outer cylinder 22. The retaining ring 26 is fixedly installed on the output shaft of the shock absorber assembly 25. The extrusion block 21 is provided with a hole adapted to the output shaft of the shock absorber assembly 25. The output shaft of the shock absorber assembly 25 and the retaining ring 26 are located within the hole.

[0039] As a supplement to the above solution, by providing the shock absorber assembly 25 and the retaining ring 26, the shock absorber assembly 25 can adopt known public technologies, and specific models are not overly restricted here. By providing the shock absorber assembly 25 and the retaining ring 26, the retaining ring 26 is used to limit the output shaft of the shock absorber assembly 25, preventing the shock absorber assembly 25 from completely separating from the extrusion block 21. When the outer cylinder 22 approaches the extrusion block 21, the output shaft of the shock absorber assembly 25 can be pushed by the mounting seat 20, achieving another buffering effect through the displacement of the output shaft of the shock absorber assembly 25. Cooperating with the above-mentioned limit block 24 and the outer cylinder 22, the rigid impact of the steel plate on the flap body 11 can be greatly reduced.

[0040] The working principle of the present utility model: In the initial position, the two flap bodies 11 are in a horizontal state. The steel plate is placed on the horizontal flap body 11 through a hoisting device, which can be a crane. The flap body 11 is pushed to flip by the push cylinder 12, and the two flap bodies 11 approach each other. The flap body 11 is provided with several avoidance grooves, and the flap body 11 forms a comb structure through the avoidance grooves for misalignment when the two flap bodies 11 approach each other. When the plate is poured from one flap body 11 to the other flap body 11, the push cylinder 12 is controlled to make the two flap bodies 11 return to the horizontal state. By providing several ear plates 13 on one side of each flap body 11, when the flap body 11 gradually flips from the horizontal to the vertical, the edge position of the plate is lifted by the ear plates 13. By providing the deformation groove 23, the end of the outer cylinder 22 forms several petal-like structures by means of the deformation groove 23. When the plate extrudes the end of the outer cylinder 22, the end of the outer cylinder 22 provided with the deformation groove 23 can approach the extrusion block 21. The petal-like structure between two adjacent deformation grooves 23 is deformed by the extrusion of the extrusion block 21. The limit block 24 can be made of rubber. When the outer cylinder 22 approaches the extrusion block 21, the end of the limit block 24 can abut against the end of the extrusion block 21, achieving another buffering and protection. By providing the shock absorber assembly 25 and the retaining ring 26, the retaining ring 26 is used to limit the output shaft of the shock absorber assembly 25, preventing the shock absorber assembly 25 from completely separating from the extrusion block 21. When the outer cylinder 22 approaches the extrusion block 21, the output shaft of the shock absorber assembly 25 can be pushed by the mounting seat 20, achieving another buffering effect through the displacement of the output shaft of the shock absorber assembly 25, realizing the buffering of the rigid impact of the plate and the support for the plate.
