[0018] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] The present invention provides an anti-slip device for a rounding and rounding machine, see Figure 1 The difference between the present invention and the prior art is that the anti-slip device comprises a multi-roller main machine 1, a column 7 is arranged on the multi-roller main machine, a lift arm 2 is arranged on the column 7, an adjustable roller 5 is arranged above the lift arm 2, one end of the adjustable roller 5 is connected to the lift arm 2, and the other end is connected to the roller angle adjustment drive device 6, and the angle between the adjustable roller and the horizontal plane is controlled by the rotation of the roller angle adjustment drive device, so as to adjust the position of the cylinder section mounted on the lift arm; a position detection sensor 4 is arranged on one side of the lift arm, which can monitor the position of the cylinder section in real time to ensure that the cylinder section can be kept in a predetermined position without displacement during the entire operation process; at the same time, a control system 3 is arranged on one side of the multi-roller main machine.

[0020] During implementation, when the cylinder segment is rolling or returning to a circle, the position detection sensor monitors the position of the cylinder segment in real time and compares it with the initial position. The angle of the roller is adjusted according to the change in the position of the cylinder segment, and a certain lateral force is applied to the cylinder segment through the principle of gravity, thereby adjusting the position of the cylinder segment on the multi-roller main machine to prevent the cylinder segment from moving on the main machine.

[0021] Example 1

[0022] In this embodiment, the anti-slip device includes a multi-roller main machine 1, a column 7 is provided on the multi-roller main machine, a lift arm 2 is provided on the column 7, an adjustable roller 5 is provided above the lift arm 2, one end of the adjustable roller 5 is connected to the lift arm 2, and the other end is connected to the roller angle adjustment drive device 6. The angle between the adjustable roller and the horizontal plane is controlled by rotating the roller angle adjustment drive device, thereby adjusting the position of the cylinder section on the adjustable roller; a position detection sensor 4 is provided on one side of the lift arm for real-time monitoring of the position of the cylinder section; a control system 3 is provided on one side of the multi-roller main machine.

[0023] Specifically, the multi-roller main machine here includes three-roller, four-roller or other forms of rolling and rounding main machines, which can effectively form the plate. The roller angle adjustment drive device is rotatably connected to the lifting support arm through a hinge. One end of the adjustable roller is rotatably connected to the lifting support arm through a rotating shaft 9, and the other end is connected to the roller angle adjustment drive device. Through the swing of the roller angle adjustment drive device, one end of the adjustable roller is lifted and lowered, thereby adjusting the angle between the adjustable roller and the horizontal plane, so that the cylinder section supported on the adjustable roller is displaced under the action of gravity, ensuring that the position of the cylinder section set on the lifting support arm will not move.

[0024] Furthermore, a plurality of position detection sensors are arranged along the length direction of the lifting arm, and the distance between the first position detection sensor and the last position detection sensor is greater than or equal to the length of the lifting arm, so that the position detection sensor can ensure real-time monitoring of the cylinder section.

[0025] At the same time, there is a gap between the adjustable roller and the lifting arm, and the gap value is 5-10mm, so that the angle between the adjustable roller and the horizontal plane can be adjusted, and the adjustable angle range is -15 degrees to 15 degrees.

[0026] Example 2

[0027] A method for using an anti-slip device for a rolling and rounding machine, which differs from the prior art in that the method comprises the following steps: a. sleeve a cylinder segment on a lifting support arm so that an adjustable roller supports the inner wall of the cylinder segment; b. lift the lifting support arm so that the roller can effectively carry the cylinder segment during the forming process, and a position detection sensor can detect the position of the cylinder segment at all times; c. the position detection sensor records the current position of the cylinder segment and transmits the position data to a control system; d. perform sheet forming work and monitor the position of the cylinder segment in real time during the process; e. adjust the angle between the adjustable roller and the horizontal plane by the action of a roller angle adjustment drive device so that the position of the cylinder segment on the lifting support arm remains unchanged; f. complete the cylinder segment forming and unload the cylinder segment.

[0028] Specifically, in step e, if the cylinder section moves outward, the roller angle adjustment drive device will be activated to make the outer side of the roller higher than the inner side, forming a certain angle, and applying a certain lateral force inward to the cylinder section; if the cylinder section moves inward, the roller angle adjustment drive device will be activated to make the inner side of the roller higher than the outer side, forming a certain angle, and applying a certain lateral force outward to the cylinder section. The roller angle adjustment drive device continuously adjusts according to the position detected by the position detection sensor. The single adjustment amount = K*T, where K is a variable coefficient and T is a constant. The value of K is determined by the amount of movement per unit time. The greater the amount of movement per unit time, the greater the value of K. Specifically, the value range of K is 0.1-2.2, and the value of T is 1 / 1000 of the total length of the roller.

[0029] In step c, a plurality of position detection sensors are arranged along the length direction of the lifting arm, and the distance between the first position detection sensor and the last position detection sensor is greater than or equal to the length of the lifting arm. In step c, the detection cycle of the position detection sensor is 2-5 seconds, which can ensure effective monitoring.

[0030] The roller angle adjustment driving device is rotatably connected to the lifting arm through a hinge. One end of the adjustable roller is rotatably connected to the lifting arm through a rotating shaft, and the other end is connected to the roller angle adjustment driving device.

[0031] Example 3

[0032] In this embodiment, the lifting arm 2 column is installed on the inner side of the multi-roller main machine 1 (not the feeding and discharging side), and the arm can perform vertical lifting movement on the column, and can adopt various driving modes such as electric and hydraulic; The position detection sensor 4 is installed on the lifting arm 2. The sensor can detect the real-time position of the cylinder section on the arm and feed back the position data to the control system 3. One end of the adjustable roller 5 is installed on the lifting arm 2 through a rotating shaft, and the other end is connected to the roller angle adjustment drive device 6. The roller angle adjustment drive device 6 is installed on the lifting arm 2 through a hinge. The roller angle adjustment drive device 6 can control the angle of the adjustable roller 5. Figure 3 as shown. Specifically, the roller angle adjustment drive device 6 can accurately control the extension length according to the input data, and can be controlled by various methods such as electric and hydraulic. The detection cycle of the position detection sensor 4 is generally between 2-5s, and the specific value can be determined according to the linear speed of the cylinder section during winding and returning.

[0033] The roller angle adjustment drive device 6 is continuously adjusted according to the position detected by the position detection sensor 4, and the single adjustment amount = K*T, where K is a variable coefficient and T is a constant. The value of K is determined by the amount of movement per unit time. The greater the amount of movement per unit time, the greater the value of K. Specifically, the value range of K is 0.1-2.2, preferably 0.5-2, and the value of T is 1 / 1000 of the total length of the roller. For example, T is related to the total length of the roller. The longer the total length of the roller, the greater the value of T, and the relationship is proportional. Taking the roller length of 2 meters as an example, the recommended value of T is 2mm.

[0034] The specific operation process is as follows Figure 4 As shown, a multi-point position detection sensor is first used to detect the position of the cylinder segment. When the cylinder segment is placed on the multi-roller main machine, the Nth detection point on the inside and the Mth detection point on the outside cannot detect the cylinder body, but the detection point between the Nth and Mth detection points can detect the cylinder body.

[0035] During the forming operation of the sheet, if the cylinder section moves inward, the N-1th detection point that could not detect the cylinder can now detect the cylinder, and the angle adjustment drive device retracts, so that the outer side of the adjustable roller is lower than the inner side, and an outward lateral force is applied to the cylinder section, so that the cylinder moves outward. Conversely, if the cylinder section moves outward, the M+1th detection point that could not detect the cylinder can now detect the cylinder, and the angle adjustment drive device extends, so that the inner side of the adjustable roller is lower than the outer side, and an inward lateral force is applied to the cylinder section, so that the cylinder moves inward, ensuring accurate control of the position of the cylinder section.

[0036] The device of the present invention can monitor the position of the cylinder section in real time and adjust the angle of the roller to ensure that the position of the cylinder section on the main machine does not move. It has the advantages of simple structure, high degree of automation, easy operation and high control accuracy.

[0037] The above content is a further detailed description of the present invention in combination with specific preferred embodiments, and it cannot be determined that the specific implementation of the present invention is limited to the above descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as falling within the scope of protection of the present invention.
