[0040] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "set / connected", "connected", etc. should be understood in a broad sense. For example, "connection" can be a wall-mounted connection, a detachable connection, or an integral connection. It can be a mechanical connection or an electrical connection. It can be a direct connection or an indirect connection through an intermediate medium. It can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0041] refer to Figures 1-12 This embodiment provides a mold-changing drive device for CZMU steel forming equipment, which is mainly suitable for a CZMU steel forming, punching and shearing device. The mold-changing drive device is installed on a roll forming machine. The roll forming machine is the core part of the entire equipment. The roll forming machine consists of a roller pressing group 6 and a roller transport group. The roller pressing group 6 is used to plastically deform the steel strip, and the roller transport group is used to transport the steel strip. The steel strip is pressed into a specific shape of the CZMU steel by a series of rollers of the roller pressing group 6. The roll forming machine can achieve efficient continuous production, reduce manual intervention, and improve the yield rate.

[0042] like Figure 1 Specifically, upper pressing rollers 61 and lower pressing rollers 62 are provided on both sides of the roller pressing group 6 and the roller transport group, and the upper pressing rollers 61 and lower pressing rollers 62 on both sides are symmetrically arranged. By setting the pressing rollers at different heights and setting the pressing surfaces at different angles, the rollers are configured to rotate continuously, and the rollers press the steel strip at corresponding pressure and speed, causing it to undergo plastic deformation and thus form the desired shape.

[0043] The shape-changing drive device is a shape-changing device for pressing C-shaped steel 4, Z-shaped steel 5, and M-shaped steel 7. Figure 9 During the pressing process, one side of the C-shaped steel 4 and the Z-shaped steel 5 needs to be pressed in the reverse direction, so the shape-changing drive device is a device for switching between positive and reverse pressing. During the pressing process, the M-shaped steel 7 needs to be pressed to form an M-shaped middle concave shape.

[0044] Specifically, the profile change drive equipment includes an avoidance mechanism 8, a profile change mechanism 3, and a roller assembly. The roller assembly is used to plastically deform the steel strip and includes a first series of profile change rollers 1 and a series of embossing rollers 9. The series of embossing rollers 9 constitute the first pressing process, while the first series of profile change rollers 1 constitute the second pressing process.

[0045] like Figure 5-6 The first series of changing rollers 1 is composed of a movable roller 11 and a fixed roller 12. The fixed roller 12 is installed at a fixed height of the roll forming machine. The movable roller 11 is driven by the changing mechanism 3 to move up and down vertically.

[0046] like Figure 3 The movable pressing roller 11 is fixed on the lifting platform 32 and is driven by the lifting motor 31 to move up and down. The upper end of the fixed pressing roller 12 serves as the first pressing zone, and the upper and lower ends of the movable pressing roller 11 are divided into the second pressing zone and the third pressing zone. The lifting motor 31 drives the lifting platform 32 to move up and down, so that the movable pressing roller 11 moves up and down, and is used to switch between the second pressing zone and the third pressing zone to cooperate with the first pressing zone to press the steel strip into a C-shape or Z-shape.

[0047] According to the pressing area, the upper end surface of the movable pressing roller 11 is set as the first pressing surface 14, the lower end surface is set as the second pressing surface 15, the upper end surface of the fixed pressing roller 12 is the first fixed pressing surface 13, and the steel strip is pressed in a C shape. Figure 5 When the movable pressing roller 11 descends to the first pressing surface 14 and faces the first fixed pressing surface 13, it is used to press the C-shaped structure. The steel strip is pressed in Z shape, such as Figure 6 When the movable pressing roller 11 rises to the second pressing surface 15 and faces the first fixed pressing surface 13, it is used to press the Z-shaped structure. It should be noted that the upper end surface is the side on the upper side of the pressing roller during rotation, and the lower end surface is the side on the lower side of the pressing roller during rotation.

[0048] Roller pressing is a process in which the steel strip is continuously processed and deformed by the continuous rotation of a series of rollers to form the required shape. Therefore, the movable pressing roller 11 and the fixed pressing roller 12 are a series of pressing roller structures arranged along the rolling path. In order to facilitate the change of shape, a lifting motor 31 and several lifting platforms 32 are set corresponding to a series of movable pressing rollers 11. One movable pressing roller 11 is equipped with a lifting platform 32, and then the lifting motor 31 is linked to the series of corresponding lifting platforms 32 through the linkage 33 to achieve the simultaneous lifting and lowering operation of all movable pressing rollers 11 in a rolling process.

[0049] During the lifting and lowering movement of the lifting platform 32 , a long slot 34 is provided on the lifting platform 32 in order to avoid the installation of other pressing rollers on the roll forming machine.

[0050] The C-shaped or Z-shaped pressing of the steel strip is divided into two pressing processes, one is the edge pressing process, and the other is the high waist pressing process. Figure 7 , the pressing edge needs to be pressed to 90° after the pressing. In order to facilitate the mold changing operation and the subsequent 90° pressing, and to reduce the over-long drive of the lifting motor 31, the pressing roller group used for the waist-high pressing part is divided into the first series of mold changing rollers 1 and the second series of mold changing rollers 2.

[0051] The first series of profile-changing rollers 1 and the second series of profile-changing rollers 2 are arranged in sequence along the pressing and transporting direction. The first series of profile-changing rollers 1 are arranged in the first half of the pressing production line for the waist-high pressing part, and the second series of profile-changing rollers 2 are arranged in the second half of the pressing production line for the waist-high pressing part.

[0052] The first set of profile-changing rollers 1 consists of a movable roller 11, a fixed roller 12, and a profile-changing mechanism 3. The second set of profile-changing rollers 2 consists of a first roller 21 and a second roller 22. Both rollers 21 and 22 are mounted at a fixed height on the roll-forming machine. The fixed roller 12 and the first roller 21 are mounted on the same side, while the movable roller 11 and the second roller 22 are mounted on the same side.

[0053] Specifically, the upper end of the first pressing roller 21 serves as a pressing zone, and the upper end and lower end of the second pressing roller 22 are divided into two pressing zones and three pressing zones. The first pressing zone cooperates with the first pressing zone for pressing, the second pressing zone cooperates with the second pressing zone for pressing, and the third pressing zone cooperates with the third pressing zone for pressing. According to the pressing zone, the upper end face of the first pressing roller 21 is set as the second fixed pressing surface 23, and the upper end face and lower end face of the second pressing roller 22 are set as the first pressing surface 24 and the second pressing surface 25 for cooperating with the first series of changing pressing rollers 1 to press the semi-formed C-shaped steel 4 or Z-shaped steel 5 to complete 90° pressing. It should be noted that the upper end face is the side on the upper side of the pressing roller during the rotation of the pressing roller, and the lower end face is the side on the lower side of the pressing roller during the rotation of the pressing roller.

[0054] By setting up the first series of profile-changing rollers 1 and the second series of profile-changing rollers 2, the length of the waist-high part is longer when being pressed, and the second half is pressed into 90 degrees to avoid the lifting movement affecting the pressing force. For the edge pressing, the edge pressing deformation is smaller than the waist-high deformation, and the corresponding pressure of the roller is smaller. During the profile-changing pressing process, only the first series of profile-changing rollers 1 can be used for pressing, or the first series of profile-changing rollers 1 and the second series of profile-changing rollers 2 can be used for pressing.

[0055] like Figure 10 The series of embossing rollers 9 include two groups of roller assemblies 91 arranged on the left and right sides, and both groups of roller assemblies 91 are provided with avoidance mechanisms 8; the two groups of roller assemblies 91 can move inward or outward under the drive of their corresponding avoidance mechanisms 8, and the avoidance mechanism 8 is used to control the roller assemblies 91 to select whether to perform the pressing process on the steel strip.

[0056] like Figure 12, the avoidance mechanism 8 includes a avoidance motor 81, a screw assembly 82 and a moving frame 83. The two groups of pressure roller assemblies 91 perform symmetrical pressing on both sides of the steel strip, respectively, to ensure perfect forming after pressing. Avoidance mechanisms 8 are provided on the frames on both sides of the equipment, and one group of avoidance mechanisms 8 drives a group of pressure roller assemblies 91 to move. The screw assembly 82 is driven by the avoidance motor 81, and the screw assembly 82 passes through the frame of the equipment and is connected to the moving frame 83. The moving frame 83 is connected to the pressure roller assembly 91 on its corresponding side through an axis. Driven by the motor, the screw assembly 82 drives the moving frame 83 to move in a straight line. The moving frames 83 on both sides of the first pressure roller group drive the pressure roller assembly 91 to move inward or outward during the process of moving to both sides or to each side. When the pressure roller assemblies 91 on both sides move inward and stop at a certain distance, it can be used for the plate rib process, such as Figure 11 When the sheet metal beading process is no longer needed, the roller assemblies 91 on both sides are moved outward, with the spacing between the two roller assemblies 91 greater than the width of the steel strip. The steel strip is then smoothly transported by the roller conveyor assembly through the first roller assembly, and the two roller assemblies 91 do not deform the steel strip. To facilitate identification and control of the movement trajectory and position of the roller assemblies 91, several position sensors 10 are installed at intervals on the upper frame beam of the equipment.

[0057] The above is only a preferred specific implementation method of the present invention, but the design concept of the present invention is not limited to this. Any technician familiar with the technical field who uses this concept to make non-substantial changes to the present invention within the technical scope disclosed by the present invention shall be deemed to infringe the protection scope of the present invention.
