Description

Technical Field

[0001] The invention relates to the technical field of straightening machines, in particular to a beating plate structure for blanking a straightening machine. Background Art

[0002] A straightening machine is a device used to straighten metal profiles, bars, pipes, wire, and other materials. A straightening machine uses straightening rollers to compress the bar material, causing it to change its straightness. Generally, there are two rows of straightening rollers, with varying numbers of rollers. There are also two-roller straightening machines, which use the angles of the two rollers (with a concave center and a hyperbolic curve) to straighten materials of varying diameters. Major types include pressure straightening machines, balanced roller straightening machines, shoe roller straightening machines, and rotary reversing straightening machines.

[0003] Traditional straightening machines (such as the straightening machine disclosed in the authorized patent with application number CN202010944909.8) are not equipped with a falling device, and the material must be pried manually to be unloaded, and the unloading is uneven, resulting in the disorderly piling and uneven ends of the steel. In addition, the staff use crowbars to pry the material, which is a lot of work. The crowbar is easy to hit the operator when prying the material, and there are many unsafe factors. In response to this situation, the prior art has proposed a straightening machine that can automatically unload the material, such as the automatic unloading straightening machine proposed in the authorized patent with application number CN202023339460.7. When the straightening machine is in use, the pipes with qualified straightness fall from the inspection table to the collecting belt for stacking. The straightened pipes directly roll freely on the unloading rack by their own gravity to achieve the purpose of unloading. This method of feeding does not have any constraints on the pipes. The impact force when the pipes fall is large. When the pipes on the collecting belt come into contact with the falling pipes, the impact force can easily cause scratches on the outer periphery of the pipes and generate noise. It can also cause the steel pipes to be placed in uneven lengths, causing difficulties in the next step of the process. In addition, the existing feeding method is prone to scratches on the outer periphery of the steel pipes and generates noise. Summary of the Invention

Detailed implementation mode

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] The present invention provides a plate hitting structure for straightening machine blanking, including a blanking rack 1. The pipe after being straightened by the straightening machine moves on the blanking rack 1. A positioning structure is provided at one end of the blanking rack 1 away from the straightening machine, and a pushing structure is provided between the positioning structure and the straightening machine. The positioning structure is used to sense the pipe. When the positioning structure senses the pipe, the pushing structure works and the pushing structure pushes the pipe to move.

[0029] A vertical plate 32 is fixedly connected to one side of the top of the blanking rack 1. The positioning structure includes a fixed plate 6 fixedly connected to the vertical plate 32. A detection plate 12 is fixedly connected to one side of the fixed plate 6 close to the push plate 5. Through the setting of the fixed plate 6, the position of the positioning structure can be adjusted according to requirements, so that the structure can adapt to pipes of various lengths. The other end of the detection plate 12 is fixedly connected with a pressure sensing sheet. When the pipe contacts the detection plate 12, the pressure sensing sheet can sense the pressure. After the pressure sensing sheet senses the pressure, the control system in the structure will control the pushing structure to work.

[0030] The pushing structure includes a sliding rod 9 fixedly connected to the vertical plate 32. A sliding sleeve 3 is movably sleeved on the outer circle of the sliding rod 9. A magnet block 11 is clamped in the middle of the bottom end of the sliding sleeve 3. One end of the magnet block 11 contacts the sliding rod 9. The middle of the other end of the magnet block 11 is fixedly connected with a handle, and the magnet block 11 and the sliding rod 9 are magnetically attracted to each other. In an embodiment of the present application, the material of the sliding rod 9 is metal iron. In this way, the position of the sliding sleeve 3 can be changed, and the sliding sleeve and the sliding rod 9 can be magnetically attracted to each other. When the two are magnetically attracted to each other, the position of the sliding sleeve 3 is fixed, which is convenient for the use of the pushing structure.

[0031] A hydraulic rod 4 is fixedly connected to the middle of the top of the sliding sleeve 3, and a push plate 5 is fixedly connected to the other end of the hydraulic rod 4. The push plate 5 contacts one side of the vertical plate 32. Through the setting of the hydraulic rod 4, the extension and contraction of the hydraulic rod 4 can change the position of the push plate 5 fixedly connected thereto, and the push plate 5 can push the pipe placed on the blanking rack 1.

[0032] A scale 2 is fixedly connected to the middle of the top of the slide rod 9. By setting the scale 2, the staff can control the distance between the push plate 5 and the detection plate 12. When this structure is in use, the push plate 5 is located in the middle of the pipe. With this setting, when the push plate 5 pushes the pipe, the pipe can be moved horizontally.

[0033] A buffer structure 8 is provided at one end of the blanking rack 1 away from the vertical plate 32 . The push plate 5 can push the pipe onto the buffer structure 8 , and the pipe moves along the buffer structure 8 under the action of gravity.

[0034] The buffer structure 8 proposed in this application includes an active roller 28, a driven roller 25, a guide roller 33 and a tensioning roller 17. The active roller 28, the driven roller 25 and the tensioning roller 17 are connected by a synchronous belt 14. A connecting structure is provided in the middle of both ends of the active roller 28, and the active roller 28 is connected to the blanking rack 1 through the connecting structure.

[0035] The connecting structure includes a bracket 31 fixedly connected to the blanking rack 1, and a rotating block rotating structure is provided on the outer side of the bracket 31. The rotating block rotating structure includes a synchronous wheel 24 movably connected to one end of the bracket 31, a connecting rod 29 movably connected to the other end of the bracket 31, and a hydraulic rod 3 22 fixedly connected to the top of the bracket 31. The end of the connecting rod 29 close to the synchronous wheel 1 24 is fixedly connected to the synchronous wheel 2 23. The synchronous wheel 1 24 and the synchronous wheel 2 23 are connected by a synchronous belt 2 20. The top of the synchronous belt 20 is horizontal. The other end of the hydraulic rod 3 22 is fixedly connected to the push block 21. The bottom of the push block 21 is fixedly connected to the top of the synchronous belt 2 20.

[0036] From the above description, it can be seen that when the hydraulic rod three 22 is extended or retracted, it can drive the push block 21 fixedly connected to it to move, and the push block 21 drives the synchronous belt 2 20 fixedly connected to it to move, and the synchronous belt 20 can drive the connecting rod 2 29 to rotate through the synchronous wheel 2 23 engaged with it.

[0037] At the middle of the other end of the second connecting rod 29, a rotating block 19 is fixedly connected. At the middle of this end of the rotating block 19, a lead screw 13 is movably connected. At the outer side of this end of the rotating block 19, a rotating motor 30 is fixedly connected. The end of the output shaft of the rotating motor 30 is fixedly connected to the middle of one end of the lead screw 13. The outer circumference of the other end of the lead screw 13 is threadedly connected with a threaded block 26. At the middle of the end of the threaded block 26 away from the bracket 31, a first second connecting rod is movably connected. The other end of the first second connecting rod is fixedly connected to the middle of the end of the driven roller 25. With such a setting, when the rotating motor 30 rotates, the rotating motor 30 can drive the lead screw 13 fixedly connected thereto to rotate. The rotation of the lead screw 13 causes the threaded block 26 to move in the direction where the lead screw 13 is located, and the distance between the driven roller 25 and the rotating block 19 can be changed.

[0038] At the middle of the other end of the rotating block 19, a first first connecting rod 27 is movably connected. The other end of the first first connecting rod 27 is fixedly connected to the middle of the end of the driving roller 28.

[0039] The guiding roller 33 is located between the driving roller 28 and the tensioning roller 17, and the guiding roller 33 is fixedly connected to the outer surface of the first synchronous belt 14. At the middle of both ends of the guiding roller 33, connecting plates 18 are movably sleeved. The other end of the connecting plate 18 is fixedly connected to the blanking frame 1. The function of the guiding roller 33 is to change the wrap angle between the first synchronous belt 14 and the driving roller 28, so that the wrap angle between the two can be greater than 120 degrees, which is convenient for the work of the buffer structure 8.

[0040] The tensioning roller 17 is located below the driving roller 28. At the middle of both ends of the tensioning roller 17, third first connecting rods are fixedly connected. The other end of the third first connecting rod is movably sleeved with a connecting rod three 16. The other end of the connecting rod three 16 is fixedly connected to the second hydraulic rod 15. The other end of the second hydraulic rod 15 is fixedly connected to the blanking frame 1. With such a setting, the telescoping of the second hydraulic rod 15 can change the horizontal position of the tensioning roller 17.

[0041] As can be seen from the above description, when the distance between the driving roller 28 and the driven roller 25 changes, the second hydraulic rod 15 drives the tensioning roller 17 to move, so that the first synchronous belt 14 can always be in a tensioned state, which is convenient for the work of the buffer structure. In order to detect the tension degree of the first synchronous belt 14, a pressure sensing piece is fixedly installed on the outer surface of the tensioning roller 17, and the pressure of the first synchronous belt 14 on the tensioning roller 17 is sensed by the pressure sensing piece, so as to judge the tension degree of the first synchronous belt 14.

[0042] In this application, the outer diameters of the driven roller 25 and the driving roller 28 are the same, and the top of the buffer structure can be in a flat state. When the buffer structure tilts under the action of the third hydraulic rod 22, the pipe can fall along the buffer structure 8, reducing the impact force when the pipe falls.

[0043] This application also includes a hydraulic station 10 and a collection tank 7. The operation of the hydraulic station 10 can control the telescoping of the first hydraulic rod, the second hydraulic rod, and the third hydraulic rod within this structure. The collection tank 7 is adapted to the buffer structure 8, and the collection tank 7 can collect the straightened pipes.

[0044] The electrical components involved in this application are all prior arts. Those skilled in the art understand their connection methods. Through those skilled in the art, all the electrical components in this application are connected to their adapted power supplies through wires, and a suitable controller is selected according to the actual situation to meet the control requirements. For the specific connection and control sequence, refer to the following description. The electrical connection is completed in the order of the sequence of operation among the electrical components. Their detailed connection means are well-known techniques in this field. The following mainly introduces the working principle and process, and no further description of the electrical control will be made.

[0045] In summary: When the stripping plate structure for the straightening machine is in use, the inclination angle of the buffer structure 8 is adjusted according to the demand. The third hydraulic rod 22 telescopes. The third hydraulic rod 22 drives the push block 21 fixedly connected thereto to move. The push block 21 drives the second synchronous wheel 23 to rotate through the second synchronous belt 20 fixedly connected thereto. The second synchronous wheel 23 drives the rotating block 19 to rotate through the second connecting rod 29 fixedly connected thereto. The rotating block 19 drives the driving roller 28 to rotate, thereby changing the deflection angle of the buffer structure 8.

[0046] When this structure is in use, the pipes straightened by the straightening machine move on the blanking frame 1. When the pipes contact the detection plate 12, the first hydraulic rod 4 drives the push plate 5 to move. The push plate 5 pushes the pipes until the pipes contact the top of the buffer structure 8. At this time, the pipes can move down along the buffer structure 8 under the action of gravity, and the pipes fall into the inner cavity of the collection tank 7.
