[0051] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only 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 ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0053] 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.
[0054] refer to Figures 1-14 This embodiment provides a layout structure for forming, punching, and shearing equipment for CZMU steel sections. The equipment includes a main control system and a feeder, a puncher, a roll-forming machine, and a shearing machine 9 arranged in sequence along the transport route of the steel strip 101. The feeder is used to place the steel strip 101 at the starting position of the production line, ensuring smooth transportation of the steel strip 101. The puncher is responsible for punching holes in the steel strip 101 before it is formed to facilitate subsequent forming and connection. The puncher can use an existing automatic flying saw design, which is easy to operate and can improve production efficiency.
[0055] The roll-forming machine, the core of the entire equipment, consists of a roller pressing unit and a roller conveyor unit. The roller pressing unit is used to plastically deform the steel strip 101, while the roller conveyor unit is used to transport the steel strip 101. The series of rollers in the roller pressing unit press the steel strip 101 into the specific shape of the CZMU steel section. The roll-forming machine enables efficient continuous production, reduces manual intervention, and improves yield.
[0056] The shearing machine 9 is responsible for cutting the formed CZMU steel into the required length after forming. The shearing machine 9 includes a cutter 92 and a mold limiter group, which can cut a variety of profiles with high efficiency and precision.
[0057] The roller forming machine is provided with a transverse seat 8 for installing a roller pressing group and a roller transport group, and the transverse seat 8 is provided with two groups on both sides. The two groups of transverse seats 8 are installed on the base, and a transverse guide device 81 is provided between the transverse seat 8 and the base. The main control system is connected to the transverse seat 8 and is provided with a transverse driving mechanism for driving the transverse seat 8 to move laterally, and for adjusting the distance for the roller pressing group and the roller transport group to allow steel strips 101 of different widths to pass through.
[0058] Specifically, upper pressing rollers and lower pressing rollers are provided on both sides of the roller pressing group and the roller transport group, and the upper pressing rollers and lower pressing rollers 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 101 at corresponding pressure and speed, causing it to undergo plastic deformation and thereby form the desired shape.
[0059] The lateral movement of the transverse seat 8 through the transverse drive mechanism is used to adjust the roller gap. By adjusting the size of the roller gap, the size and shape of the processed steel strip 101 can be controlled. Since the roller forming machine is a series of rollers that rotate and press, the pressing line for forming the steel strip 101 is very long, so the transverse drive mechanism is divided into multiple groups of sub-transverse drive mechanisms, and then a group of sub-transverse drive mechanisms is set up with a group of motor drive groups to control the adjustment of the roller gap in the roller forming machine in different areas. This can avoid the excessive standby control of a single group of transverse drive mechanisms and insufficient motor drive force, resulting in inadequate adjustment of the front and rear gaps. For the control of multiple groups of sub-transverse drive mechanisms, an encoder is set in the motor drive group, which can realize accurate gap adjustment of multiple motor drive groups at the same time. This can avoid the situation where the front and rear gaps are adjusted to different sizes.
[0060] The roll forming machine further comprises a first roller group 1, a second roller group 2, a third roller group 3 and a fourth roller group 4 for pressing different shapes, such as Figure 4 , the first roller pressing group is used for the rib pressing process 12 of the steel strip 101, and is used for the deformation pressing of the middle of the M shape. The second roller pressing group 2 is used for the edge pressing process of the steel strip 101, as the first edge pressing process 21, the edge of the steel strip 101 is pressed for the first time to obtain an edge of a corresponding shape. The third roller pressing group 3 is used for the edge pressing process of the steel strip 101, as the second edge pressing process 36, the edge of the steel strip 101 is pressed for the second time to obtain an edge of a corresponding shape. The fourth roller pressing group 4 is used for the waist-high pressing process 45 of the waist-high part of the steel strip 101, and is the main pressing process for forming Z-shaped and U-shaped steel. After being pressed and formed by the roller forming machine in this embodiment, the final steel strip 101 can be pressed to have different shapes, such as Figure 5 , including but not limited to these five types, the first type C-shaped steel 102, the second type M-shaped steel 103, the third type inward-facing C-shaped steel 104, the fourth type inward-facing M-shaped steel 105, and the fifth type Z-shaped steel 106.
[0061] The coordination structure between the four pressing roller processes of the first pressing roller group 1, the second pressing roller group 2, the third pressing roller group 3 and the fourth pressing roller group 4 is designed as follows: an avoidance mechanism 5 is provided in the first pressing roller group 1 and the second pressing roller group 2, and the main control system drives the corresponding roller pressing groups in the first pressing roller group 1 and the second pressing roller group 2 through the avoidance mechanism 5 to press the steel strip 101 or avoid the transportation of the steel strip 101 during transportation, and is used to select whether to perform the rib pressing process 12 of the first pressing roller group 1 and the first edge pressing process 21 of the second pressing roller group 2 to meet the requirements of whether to form the inner buckle edge C-shaped steel 104 and M-shaped steel 103. The third pressing roller group 3 and the fourth pressing roller group 4 are both provided with a changing mechanism 6. The roller pressing groups corresponding to the third pressing roller group 3 and the fourth pressing roller group 4 include a movable pressing roller 31 and a fixed pressing roller 34. The movable pressing roller 31 is linked with the changing mechanism 6. The main control system moves the movable pressing roller 31 through the driving action of the changing mechanism 6, and can select C-shaped or Z-shaped pressing work.
[0062] like Figure 7 The avoidance mechanism 5 includes a drive motor 51, a screw assembly 52, and a movable frame 53. The roller pressing groups within the first and second roller groups 1 and 2 are divided into two groups of roller assemblies 11 on the left and right sides, respectively, which perform symmetrical pressing on both sides of the steel strip 101 to ensure perfect forming after pressing. Avoidance mechanisms 5 are installed on the frames on both sides of the equipment, and one avoidance mechanism 5 drives the movement of one group of roller assemblies 11.
[0063] The screw assembly 52 is driven by the driving motor 51. The screw assembly 52 passes through the frame of the device and is connected to the mobile frame 53. The mobile frame 53 is connected to the pressure roller assembly 11 on the corresponding side through an axis. Under the drive of the driving motor 51, the screw assembly 52 causes the mobile frame 53 to move linearly. Figure 6 The movable frames 53 on both sides of the first roller assembly 1 drive the roller assembly 11 to move inward or outward when moving to both sides or to each side. When the roller assemblies 11 on both sides move inward and stop at a certain distance, they can be used for the steel strip 101 rib beading process 12. When the steel strip 101 rib beading process 12 is not needed, the roller assemblies 11 on both sides are moved outward. The distance between the two roller assemblies 11 is greater than the width of the steel strip 101. At this time, the steel strip 101 is smoothly transported through the first roller assembly 1 by the roller transport assembly, and the two roller assemblies 11 do not cause compression deformation to the steel strip 101.
[0064] In order to facilitate identification and control of the movement trajectory and position of the pressure roller assembly 11, a number of position sensors 7 are arranged at intervals on the upper frame beam of the equipment.
[0065] The second roller group 2 and the first roller group 1 are both selective processes that can choose to press the steel strip 101 into shape or not, so the position, connection and drive of the avoidance mechanism 5 provided in the second roller group 2 are consistent with those of the first roller group 1. The drive mechanism for driving the screw assembly 52 by the drive motor 51 in the first roller group 1 and the second roller group 2 is a split drive mechanism, that is, the screw assembly 52 provided in the first roller group 1 and the second roller group 2 is driven by the independent drive motor 51 provided in the first roller group 1 and the second roller group 2, which can avoid one motor being driven too long, resulting in the rear end screw drive being weak and unable to drive the moving frame 53 to the correct position. Encoders are installed in the motors of the second pressure roller group 2 and the first pressure roller group 1. The encoders are used to calibrate and control the drive of the two motors. If both the second pressure roller group 2 and the first pressure roller group 1 need to avoid each other, the drive strokes of the motors of the second pressure roller group 2 and the first pressure roller group 1 can be calibrated at the same time to ensure that the movement strokes of the second pressure roller group 2 and the first pressure roller group 1 are consistent. If the pressure roller stroke of the second pressure roller group 2 or the first pressure roller group 1 is different, two or three motors can be installed in the second pressure roller group 2 or the first pressure roller group 1 for segmented drive, and encoders can also be configured for calibration to ensure consistent strokes.
[0066] like Figure 10 The mold changing mechanism 6 includes a lifting motor 61 and a lifting platform 62. The movable pressing roller 31 is fixed on the lifting platform 62 and is driven by the lifting motor 61 to move up and down. The rollers used for pressing and forming in the third pressing roller group 3 and the fourth pressing roller group 4 are set on both sides as fixed pressing rollers 34 and movable pressing rollers 31. The upper end of the fixed pressing roller 34 serves as the first pressing area; the upper end and lower end of the movable pressing roller 31 are divided into the second pressing area and the third pressing area. According to the pressing area, the upper end surface of the movable pressing roller 31 is set as the first pressing surface 32, and the lower end surface is set as the second pressing surface 33. The upper end surface of the fixed pressing roller 34 is the fixed pressing surface 35. When the movable pressing roller 31 descends to the first pressing surface 32 and faces the fixed pressing surface 35, it is used to press the C-type structure. When the movable pressing roller 31 rises to the second pressing surface 33 and faces the fixed pressing surface 35, it is used to press the Z-type structure. Figure 11 It should be noted that the upper end surface is the side on the upper side of the pressure roller during the rotation of the pressure roller, and the lower end surface is the side on the lower side of the pressure roller during the rotation of the pressure roller.
[0067] Roller pressing is a process in which the steel strip 101 is continuously processed and deformed by the continuous rotation of a series of rollers to form the required shape. Therefore, the movable pressing roller 31 and the fixed pressing roller 34 are a series of pressing roller structures arranged along the rolling path. In order to facilitate the change of shape, a lifting motor 61 is set corresponding to a series of movable pressing rollers 31, and a lifting platform 62 is configured for each movable pressing roller 31. Then the lifting motor 61 is linked to the series of corresponding lifting platforms 62 through a linkage 63 to achieve the simultaneous lifting and lowering operation of all the movable pressing rollers 31 in a rolling process.
[0068] When the fourth roller group 4 performs waist-high pressing of the steel strip 101, Figure 12 , the pressing edge needs to be pressed to 90° after pressing. In order to facilitate the operation of changing the mold and the subsequent 90° pressing, and to reduce the over-long drive of the lifting motor 61, the roller pressing group in the fourth pressing roller group 4 is divided into the front half pressing group and the rear half pressing group.
[0069] The front half of the pressing group consists of a movable pressing roller 31 and a fixed pressing roller 34, while the back half of the pressing group consists of a first pressing roller 41 and a second pressing roller 42. The fixed pressing roller 34 is located on the same side as the first pressing roller 41, and the movable pressing roller 31 is located on the same side as the second pressing roller 42. The second pressing roller 42 also has a first pressing surface 43 and a second pressing surface 44. The first pressing surface 43 and the first pressing surface 32 cooperate to press the steel belt 101 to form a C-shaped structure, while the second pressing surface 44 and the second pressing surface 33 cooperate to press the steel belt 101 to form a Z-shaped structure.
[0070] The first half pressing group adopts a changing mechanism 6 in conjunction with a movable pressing roller 31 to realize the switching between C-type and Z-type to meet the needs of pressing steel strips 101 of different shapes. The second half pressing group adopts a second pressing roller 42 with a pressing surface 43 and a second pressing surface 44 at the upper and lower ends to cooperate with the pressing of the steel strip 101 that has been half-formed into a C-type or Z-type in the first half to complete 90° pressing.
[0071] The second half of the fourth roller set 4 is pressed using non-elevable rollers. This is because the area pressed by the fourth roller set 4 is the waist-high portion, where the deformation is longer. The second half is pressed at 90° to prevent lifting and lowering from affecting the pressing force. The third roller set 3 presses the second side, where deformation is smaller than that of the waist-high portion. Therefore, during the changeover pressing process, only the movable roller 31 can be used for pressing, or the same structure as the fourth roller set 4 can be used, with both the first and second half sections configured.
[0072] like Figure 5 , the roll forming machine in the pressing process, preparation includes but not limited to Figure 5In this shape, the first type C-shaped steel 102 is formed by the first and second roller groups 1 and 2 giving way when the steel strip 101 enters the roll-forming machine at its starting position, and the third and fourth roller groups 3 and 4 (with the movable roller 31 descending and the first side pressing) perform pressing. The second type M-shaped steel 103 is formed based on the C-shaped steel 102. When the steel strip 101 enters the roll-forming machine at its starting position, the second roller group 2 gives way, and the first roller group 1 performs rib embossing of the steel strip 101, and the third and fourth roller groups 3 and 4 perform pressing in cooperation. The third type C-shaped steel with an inner buckle edge 104 is formed by the first roller group 1 giving way when the steel strip 101 enters the roll-forming machine at its starting position, and the second, third, and fourth roller groups 2 and 3 (with the movable roller 31 descending and the first side pressing) perform pressing. The fourth type of inward-facing M-shaped steel 105 is formed by rolling the steel strip 101 from its starting position into the roll-forming machine using the first, second, third, and fourth roller sets 1, 2, 3, and 4 (with the movable roller 31 descending and performing first-side pressing). The fifth type of Z-shaped steel 106 is formed by rolling the steel strip 101 from its starting position into the roll-forming machine using the first and second roller sets 1, 2, and 3 (with the movable roller 31 ascending and performing second-side pressing) after the first and second roller sets 2 move out of the way.
[0073] The shearing machine 9 includes a shearing window, a set of cutters 92 arranged in the shearing window, and a model limiter group, and is capable of shearing a variety of profiles with high efficiency and precision.
[0074] Specifically, the shearing window is provided with a first window 91 and a second window 99. The second window 99 is connected to the first window 91 and is provided on one side of the first window 91. The second window 99 is located below the first window 91. The model limiting group is provided with a first limiting plate 93 and a second limiting plate 96. The first limiting plate 93 and the second limiting plate 96 are relatively arranged on both sides of the first window 91, and the lower end of the first limiting plate 93 extends into the second window 99.
[0075] The first limiting plate 93 is provided with a first mold hole 94 and a second mold hole 95 on its upper and lower sides. The second limiting plate 96 is provided with a third mold hole 97. The first mold hole 94 and the third mold hole 97 are both located in the first window 91, and the second mold hole 95 is located in the second window 99. A limit block 98 is detachably provided at the lower edge of the first window 91.
[0076] Among them, the first model hole 94 and the third model hole 97 are paired to form a C-shaped model hole. The second model hole 95 and the third model hole 97 are paired to form a Z-shaped model hole. The first model hole 94, the third model hole 97 and the limit block 98 are matched to form an M-shaped model hole. The specific structure of the adapted steel plate after forming is as follows Figure 5 .

The first model hole 94 and the third model hole 97 are also provided with a fourth folding hole. In order to adapt to the folding of the C-shaped steel 102 or the Z-shaped steel 106, the setting of the inner folding or the inclined folding, the first folding hole, the third folding hole, and the fourth folding hole are set as horizontal horizontal holes, and the second folding hole is set as an inclined hole. When shearing the C-shaped steel 102 or the Z-shaped steel 106, the first folding hole, the second folding hole, and the third folding hole can be selected according to the shape of the folding to match the appropriate folding holes.
[0078] At the same time, in order to adapt to the different size specifications of the C-shaped steel 102, the Z-shaped steel 106, and the M-shaped steel 103 during shearing, the first limiting plate 93 and the second limiting plate 96 are configured to be movable within the first window 91 and the second window 99.
[0079] Specifically, a first slide rail and a second slide rail are vertically arranged on both sides of the first window 91, the first limit plate 93 and the second limit plate 96 are slidably placed on the first slide rail and the second slide rail, and a third slide rail is horizontally arranged above the first window 91, and the first slide rail is slidably connected to the third slide rail.
[0080] Correspondingly, the first limit plate 93 and the second limit plate 96 are connected to a first cylinder and a second cylinder, and the third slide rail is driven by the third cylinder. The first cylinder is a lifting cylinder, which is used to drive the first limit block 98 to move up and down along the first slide rail. The second cylinder is a lifting cylinder, and the third cylinder is a telescopic cylinder. The second cylinder is used to drive the second limit block 98 to move up and down along the second slide rail, and the third cylinder is used to drive the second slide rail to move left and right along the third slide rail, thereby realizing the left and right movement of the second limit block 98. Figure 13 As shown, when shearing the small-sized Z-shaped steel 106 , the up and down movement of the first limit block 98 can be coordinated with the up and down and left and right movement of the second limit block 98 to adjust the Z-shaped model hole to a size suitable for shearing the small-sized Z-shaped steel 106 .
[0081] In the shearing machine 9, the shearing of M-shaped steel 103 is involved. In the assembly of the M-shaped model hole, a detachable limiting hole is used for setting. The detachable setting can be removed when the M-shaped model hole is not in use, thereby not affecting the shearing of C-shaped steel 102 and Z-shaped steel 106.
[0082] like Figure 14The detachable arrangement is as follows: a plug-in slot is provided at the bottom edge of the first window 91, and a plug-in hole is provided below the stopper 98; the plug-in hole is inserted into the plug-in slot. The plug-in hole and the plug-in slot are screwed together, and a through slot is provided below the first window 91 for accommodating the screw installation operation. When the stopper 98 is no longer needed, it can be removed by releasing the screw lock.
[0083] 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.
