Description

Technical Field

[0001] This application relates to the field of automated machining technology, specifically to an automatic rolling device. Background Technology

[0002] Bending and rolling technology is a metal processing technique that mainly involves plastically deforming flat metal materials (such as steel plates, heating elements, etc.) into cylindrical, arc-shaped, or other curved structures. This product is widely used in the automotive, construction, energy, aerospace and other fields.

[0003] However, the current bending and rolling method is still mainly done manually by using bench vises and tools such as wrenches and pliers to bend sheet metal and other parts. Due to the limitations of workers' technical skills and experience, the quality of the products produced is inconsistent. In addition, manual bending is slow and labor-intensive, resulting in low bending efficiency and low product quality.

[0004] Therefore, how to design a reasonable and efficient automatic rolling device has become a problem that needs to be solved in this field. Utility Model Content

[0005] In view of this, this application proposes an automatic rolling device, the automatic rolling device comprising: The coil end includes: a die roller and a power roller assembly, wherein the die roller and the power roller assembly rotate in opposite directions, and when the die roller and the power roller assembly rotate, they squeeze and curl the material sandwiched between the die roller and the power roller assembly; The control unit includes a material position detector. Based on the material position detected by the material position detector, the power roller assembly rotates in the forward or reverse direction, causing the extruded material to be clamped between the die roller and the power roller assembly and bent into a circle.

[0006] Preferably, the coil end further includes: a die roller mounting base; The mold roller is mounted on the mold roller mounting base.

[0007] More preferably, the coil end further includes: a servo indexing plate; The servo indexing plate is mounted on the mold roller mounting base, and the servo indexing plate is provided with multiple mold rollers of different diameters. The servo indexing plate rotates to switch between using mold rollers of different diameters; or The coil end also includes: a rotary cylinder; The rotary cylinder is mounted on the mold roller mounting base, and the mold roller mounting base is provided with multiple mold rollers of different diameters. The rotary cylinder controls the rotation of the mold roller mounting base to switch between using mold rollers of different diameters.

[0008] Preferably, the coil end further includes: a die roller feeding mechanism; The mold roller mounting base is slidably connected to the mold roller feeding mechanism, so that the mold roller moves along the direction of the mold roller feeding mechanism to the coil position or away from the coil position.

[0009] More preferably, the coil end further includes: a feed motor; The feed motor is electrically connected to the mold roller mounting base, and controls the mold roller mounting base to slide in the mold roller feeding mechanism.

[0010] More preferably, the coil end further includes: a sensor bracket; The sensor bracket is disposed in the mold roller mounting base, and the material position detector is disposed on the sensor bracket.

[0011] More preferably, there are two material position detectors, which are respectively arranged on both sides of the sensor bracket and monitor the monitoring areas on both sides of the mold roller.

[0012] Preferably, the control terminal further includes a motion component, which controls the rotation of the power roller group, and the rotation of the power roller group drives the mold roller to rotate.

[0013] More preferably, the motion component includes: a power motor, a transmission pulley, a transmission belt, and a power roller support; The power roller assembly is mounted on the power roller support; The transmission pulley is coaxially arranged with the power roller assembly. The transmission belt is wound around the outside of the transmission pulley. The power motor is electrically connected to the transmission pulley. The power motor controls the rotation of the transmission pulley, drives the power roller assembly to rotate, and thus drives the mold roller to rotate.

[0014] More preferably, the material position detector is a laser sensor: The laser sensor illuminates the monitoring areas on both sides of the mold roller. When the laser sensor detects that there is no material in the monitoring area on either side of the mold roller, the power roller assembly changes its rotation direction, causing the squeezed material to be clamped between the mold roller and the power roller assembly and bent into a circle.

[0015] In the automatic rolling device proposed in this application, the material sandwiched between the die roller and the power roller assembly is squeezed and rolled when the die roller and the power roller assembly rotate. Simultaneously, the power roller assembly rotates forward or backward based on the material position monitored by the material position detector, causing the squeezed material to be sandwiched between the die roller and the power roller assembly and bent into a circle. This achieves automatic rolling of the material, freeing up worker labor. Furthermore, this application ensures the quality and efficiency of material bending and improves the consistency of rolling. In addition, this application has a lightweight structure, is easy to operate, and has low manufacturing costs.

[0016] Other features and advantages of this application will be described in detail in the following detailed description section. Attached Figure Description

Detailed Implementation

[0019] The technical solution of this application will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] like Figure 1-4 As shown, the automatic rolling device provided in this application includes a rolling end and a control end. The rolling end is used to squeeze and bend the material to be rolled into a circle, and the control end is used to control the rolling end.

[0021] The coil end includes a die roller 11 and a power roller assembly 12. The die roller 11 and the power roller assembly 12 rotate in opposite directions, thus squeezing and coiling the material sandwiched between them as they rotate. The power roller assembly 12 specifically consists of two synchronously rotating power rollers, arranged in a "V" shape with the die roller 11 as shown in the attached diagram. When the power roller assembly 12 rotates counterclockwise, it drives the die roller 11 to rotate clockwise using friction; conversely, when the power roller assembly 12 rotates clockwise, it drives the die roller 11 to rotate counterclockwise using friction.

[0022] The control unit includes a material position detector 21. This detector monitors the position of the material between the die roller 11 and the power roller assembly 12. Based on the material position detected by the detector, the power roller assembly 12 rotates clockwise or counterclockwise to adjust the position and curling direction of the material being compressed between the die roller 11 and the power roller assembly 12, until the material is bent into a circle. This process can also be understood as follows: when the power roller assembly 12 rotates clockwise, one end of the material adheres to the outer circumference of the die roller 11 and is compressed and bent; when the power roller assembly 12 rotates counterclockwise, the material moves in the opposite direction, and its other end adheres to the outer circumference of the die roller 11 and is compressed and bent. Therefore, to curl the material into a circle, the die roller 11 and the power roller assembly 12 need to repeatedly change their rotation direction so that both ends of the material are curled. It is understood that "clockwise" and "counterclockwise" here refer to the clockwise and counterclockwise directions, respectively.

[0023] Thus, this application uses the material position detector 21 to monitor the position of the material between the die roller 11 and the power roller group 12, and determines whether the power roller group 12 needs to rotate in the forward or reverse direction, thereby adjusting the position of the material being squeezed and the direction of being rolled, so as to ensure that the material is always between the die roller 11 and the power roller group 12 until it is bent into a circle.

[0024] Regarding the monitoring method of the material position detector 21, in one specific embodiment, the material position detector 21 is a laser sensor, which illuminates the monitoring areas on both sides of the mold roller 11. This monitoring area can be a specific region or a point, such as the angle between the two sides of the mold roller 11 and the two power rollers as shown in the attached figure. When the laser sensor detects that there is no material in the monitoring area on either side of the mold roller 11, it indicates that one end of the material is about to detach from one of the power rollers. The power roller assembly 12 then changes its rotation direction, and simultaneously, the mold roller 11 changes its rotation direction, causing the compressed material to move in the opposite direction. This prevents the material from detaching from the power rollers, keeping it constantly sandwiched between the mold roller 11 and the power roller assembly 12 until it bends into a circle.

[0025] Depending on the specific structure of the coil end, in some specific embodiments, the coil end further includes: a die roller mounting base 13. The die roller 11 is disposed on the die roller mounting base 13.

[0026] To meet different roll material requirements, this application can also provide multiple die rollers 11 with different diameters. The roll material end also includes a servo indexing plate (not shown in the figure) or a rotary cylinder 14, both of which can perform rotational movements. When using the servo indexing plate, the servo indexing plate is mounted on the die roller mounting base 13, and multiple die rollers 11 with different diameters are provided on the servo indexing plate. The servo indexing plate rotates to switch between using die rollers 11 with different diameters. When using the rotary cylinder 14, the rotary cylinder 14 is mounted on the die roller mounting base 13, and multiple die rollers 11 with different diameters are provided on the die roller mounting base 13. The rotary cylinder 14 controls the rotation of the die roller mounting base 13 to switch between using die rollers 11 with different diameters.

[0027] Additionally, the coil end also includes a die roller feeding mechanism 15. This die roller feeding mechanism 15 is used to push the die roller 11 to the coil position. The die roller mounting base 13 is slidably connected to the die roller feeding mechanism 15. Specifically, the die roller mounting base 13 can be provided with a groove, and the die roller feeding mechanism 15 can be provided with a slide rail. The slide rail and the groove cooperate with each other, so that the die roller 11 can move along the direction of the die roller feeding mechanism 15 to or away from the coil position.

[0028] The coil end also includes a feed motor (not shown in the figure). This feed motor is electrically connected to the die roller mounting base 13 and controls the die roller mounting base 13 to slide in the die roller feeding mechanism 15.

[0029] Regarding the installation position of the material position detector 21 in this application, the coil end also includes a sensor bracket 16. The material position detector 21 is disposed on the sensor bracket 16, and the sensor bracket 16 is disposed in the die roller mounting base 13, so that the material position detector 21 can be fixed in the die roller mounting base 13 to realize the monitoring of the monitoring areas on both sides of the die roller 11. Preferably, there are two material position detectors 21, which are respectively disposed on both sides of the sensor bracket 16 and correspondingly monitor the monitoring areas on both sides of the die roller 11.

[0030] In some specific embodiments, the control terminal further includes a motion component. This motion component controls the rotation of the power roller assembly 12, which, when rotating, drives the mold roller 11 to rotate via friction.

[0031] The motion assembly may specifically include: a power motor 221, a transmission pulley 222, a transmission belt 223, and a power roller support 224. The power roller assembly 12 is mounted on the power roller support 224, the transmission pulley 222 is coaxially mounted with the power roller assembly 12, the transmission belt 223 is wound around the outside of the transmission pulley 222, the power motor 221 is electrically connected to the transmission pulley 222 to control the rotation of the transmission pulley 222, the rotation of the pulley 222 drives the power roller assembly 12 to rotate, thereby driving the mold roller 11 to rotate.

[0032] The above describes the structure of the automatic rolling device provided in this application. The following section, in conjunction with... Figure 2-4 This example illustrates how an automatic rolling device works when performing bending and rolling operations.

[0033] First, such as Figure 2 As shown, the material is placed between the power roller assembly 12. When the external start button is pressed to begin bending, the die roller feeding mechanism 15 pushes the die roller mounting base 13 and the die roller 11 towards the power roller assembly 12 until they reach the coil position. At this time, the die roller 11 compresses the material and begins to bend. When the material position detector 21 detects material within the detection area, the power roller assembly 12 begins to rotate clockwise, and the die roller 11 rotates counterclockwise simultaneously. When the material moves to... Figure 3 In the indicated state, when the material position detector 21 detects that the left side of the material is about to detach from the left power roller, the power motor 221 changes its rotation direction, controlling the power roller assembly 12 to start rotating counterclockwise, and the die roller 11 simultaneously starts rotating clockwise, thus continuing to maintain the material in the opposite direction of the extrusion and bending action. Similarly, when the material position detector 21 detects that the right side of the material is about to detach from the right power roller, the power motor 221 also changes its rotation direction, thus repeating this cycle to ensure that the material is always between the two power rollers until it is bent into the desired shape. Figure 4 The circular shape shown.

[0034] In the automatic rolling device proposed in this application, the material sandwiched between the die roller and the power roller assembly is squeezed and rolled when the die roller and the power roller assembly rotate. Simultaneously, the power roller assembly rotates forward or backward based on the material position monitored by the material position detector, causing the squeezed material to be sandwiched between the die roller and the power roller assembly and bent into a circle. This achieves automatic rolling of the material, freeing up worker labor. Furthermore, this application ensures the quality and efficiency of material bending and improves the consistency of rolling. In addition, this application has a lightweight structure, is easy to operate, and has low manufacturing costs.
