DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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] In order to solve the technical problem that the steel plate 2 is deflected when being conveyed to the die table, resulting in asymmetric folding angles, thereby causing inaccurate overall dimensions and affecting subsequent installation, the following preferred technical solutions are provided: like Figure 1 - Figure 3 and Figure 7 - Figure 8 As shown, a Z-shaped steel deformation processing equipment comprises a lower die table 1, a steel plate 2 is conveyed to the lower die table 1 by a feeding device, the width of the steel plate 2 is greater than that of the lower die table 1, columns 3 are fixed on both sides of the lower die table 1, a crossbeam 4 is fixed on the top of the two columns 3, the crossbeam 4 spans over the lower die table 1, a guide rail 5 is fixed on the bottom surface of the crossbeam 4, the guide rail 5 is arranged horizontally, a slide 6 is slidably connected to the guide rail 5, a first cylinder 7 is fixedly connected to the side wall of the column 3, the movable end of the first cylinder 7 is fixed to the side wall of the slide 6, and a calibration component 8 is fixedly connected to the bottom surface of the slide 6; The first cylinder 7 is used to push the slide 6 to move, thereby driving the calibration component 8 to move. The length of the calibration component 8 is set corresponding to the length of the steel plate 2. The calibration components 8 on both sides of the lower die table 1 can be used to center and calibrate the steel plate 2 on the lower die table 1 to ensure that the folding distance and angle at various locations are consistent during folding, thereby avoiding asymmetric folding angles, resulting in inaccurate overall dimensions and affecting subsequent installation problems.

[0020] On both sides of the calibration component 8, there are symmetrically penetrating sliding connections with the edge adjustment component 9. When different hemming widths are required for welding or bolt connection, or when the hemming width needs to be adjusted due to limited installation space, the calibrated steel plate 2 is translated through the edge adjustment component 9, thereby changing the protruding distance of the steel plate 2 on the lower die table 1 to achieve the purpose of adjusting the hemming distance; on the side walls of the cross beam 4, there are symmetrically fixed brackets 10. On the side wall of one of the brackets 10, there is a fixed connection with the first hemming component 20. On one side of the lower die table 1, there is a fixed installation of the second hemming component 30. On the top surface of the cross beam 4, there is a fixed connection with the second cylinder 40. The movable end of the second cylinder 40 is fixedly connected with the upper die 50. After the steel plate 2 is calibrated and the edge is adjusted, the second cylinder 40 drives the upper die 50 to press down to fix the steel plate 2. The first hemming component 20 and the second hemming component 30 are respectively used for hemming the long sides of the steel plate 2.

[0021] The calibration component 8 includes a connecting plate 81, the connecting plate 81 is fixed to the bottom surface of the sliding table 6, on the bottom surface of the connecting plate 81, there is a fixed connection with a bracket 82, on the outer wall of one side of the bracket 82, there is a fixed connection with a back plate 83, on the side wall of the back plate 83, there is an embedded pressure mechanism 84, the movable end of the pressure mechanism 84 is fixedly connected with a pressing plate 85, on the side wall of the pressing plate 85, there is a fixed connection with a pressure sensor 86. The calibration component 8 moves downward towards the lower die table 1 under the drive of the sliding table 6. At this time, the pressing plates 85 on both sides of the lower die table 1 respectively abut against the long sides of the steel plate 2, so that the pressure sensor 86 can detect the pressure received by each pressing plate 85. By detecting whether the pressures received by each pressure sensor 86 are balanced, it is judged whether the steel plate 2 is skewed. If the steel plate 2 is skewed, its attitude is calibrated through the thrust of the pressing plate 85 to make the edge of its hemming parallel to the edge of the lower die table 1.

[0022] The first hemming component 20 includes two first hydraulic rods 201 symmetrically fixed to the side wall of the bracket 10. The movable ends of the two first hydraulic rods 201 are jointly fixedly connected with a lower pressing plate 202. After adjusting the hemming distance of the steel plate 2, the first hydraulic rod 201 drives the lower pressing plate 202 to press down to hem one long side of the steel plate 2, so that the steel plate 2 bends downward with the lower die table 1 as the boundary.

[0023] The second hemming component 30 includes two second hydraulic rods 301 fixedly installed on one side of the lower die table 1. The movable ends of the two second hydraulic rods 301 are jointly fixedly connected with an upper pressing plate 302. After adjusting the hemming distance of the steel plate 2, the second hydraulic rod 301 drives the upper pressing plate 302 to hem the other long side of the steel plate 2, so that the steel plate 2 bends upward with the upper die 50 as the boundary.

[0024] Specifically, when performing Z-shaped processing on the steel plate 2, first, the steel plate 2 is conveyed to the upper surface of the lower die table 1 by the feeding device. At this time, the steel plate 2 is not fixed. To ensure that the hemming distances and folding angles at various positions of the steel plate 2 are consistent during hemming, the attitude of the steel plate 2 is calibrated by the calibration assembly 8. During this process, the two first cylinders 7 are started simultaneously, and the connected sliders 6 are pushed towards the lower die table 1. The two calibration assemblies 8 gradually approach the steel plate 2, so that the abutting plates 85 abut against the long side of the steel plate 2. By abutting against the long side of the steel plate 2 when the two abutting plates 85 approach, the skewed steel plate 2 can be adjusted to make the edge of its hemming parallel to the edge of the lower die table 1, avoiding the rejection of the steel plate 2 due to inconsistent hemming distances during hemming and reducing material losses; The pressure sensor 86 on the side wall of the abutting plate 85 can detect the mechanical pressure it receives and convert it into an electrical signal for output. This is prior art. If the steel plate 2 is in a skewed attitude, according to the different pressures detected by the pressure sensor 86, the staff can judge the skewing degree of the steel plate 2 accordingly, and promptly check the feeding device to adjust the positioning accuracy during feeding. After the steel plate 2 is adjusted, the abutting plate 85 continues to approach the lower die table 1. At this time, the pressures received by the pressure sensors 86 at various positions tend to be the same, and the first cylinder 7 stops to avoid excessive squeezing pressure on the steel plate 2 by the abutting plates 85 on both sides of the steel plate 2, causing the middle of the steel plate 2 to bend upward. When the hemming distance does not need to be adjusted, the upper die 50 is directly driven by the second cylinder 40 to press down to fix the steel plate 2. Then, the first hydraulic rod 201 drives the lower pressing plate 202 to press down to hem one long side of the steel plate 2, causing the steel plate 2 to bend downward with the lower die table 1 as the boundary. The second hydraulic rod 301 drives the upper pressing plate 302 to hem the other long side of the steel plate 2, causing the steel plate 2 to bend upward with the upper die 50 as the boundary, completing the Z-shaped bending of the steel plate 2.

[0025] To solve the technical problem that according to different usage requirements, the hemming distance of the Z-shaped steel usually needs to be changed, and in the existing equipment, it is usually adapted to the steel plate 2 through a specific mold, which is not convenient to adjust the hemming distance of the steel plate 2, as Figure 4 - Figure 6 shown, the following preferred technical solutions are provided: The pressing mechanism 84 includes a plunger cylinder 841 fixedly connected through the side wall of the back plate 83. A slide bar 842 is slidably connected through one end of the plunger cylinder 841. A piston 843 is sealingly slidably connected to the inner wall of the plunger cylinder 841. The side wall of the piston 843 is fixedly connected to one end of the slide bar 842. The rodless cavity of the plunger cylinder 841 is filled with hydraulic oil. A lead-out pipe 844 is fixedly connected through the end of the plunger cylinder 841 away from the slide bar 842. An electromagnetic valve 845 is fixedly installed on the lead-out pipe 844. The electromagnetic valve 845 is in a normally closed state. When calibrating the posture of the steel plate 2, the abutting plate 85 will not push the slide bar 842 to move. A plurality of lead-out pipes 844 on both sides of the lower die table 1 are respectively connected in one-to-one correspondence through pipelines. The length of the pipeline has a certain margin to adapt to the distance change when the two calibration components 8 move. And the pipeline is filled with pressure oil. When it is necessary to adjust the hemming distance of the steel plate 2, the electromagnetic valve 845 is opened, and the rodless cavities of the plunger cylinders 841 on both sides of the lower die table 1 are in a communicating state.

[0026] A first through hole 101 is formed in the bottom side wall of the bracket 10. A second through hole 11 is formed in the bottom side wall of the lower die table 1 corresponding to the position of the first through hole 101. The first through hole 101 and the second through hole 11 are provided for passing through the pipelines, so that the pipelines are orderly distributed at the bottom, avoiding entanglement caused by mess.

[0027] The edge-adjusting component 9 includes a spline shaft 91 slidably connected through the side wall of the bracket 82. Through the setting of the spline shaft 91, it can only slide along the side wall of the bracket 82 without rotating. One end of the spline shaft 91 located inside the bracket 82 is fixedly connected with a limiting plate 92. The limiting plate 92 is elastically connected with the side wall of the bracket 82 through a spring 93. And the spline shaft 91 passes through the inner ring of the spring 93. The sliding distance of the spline shaft 91 is limited by the limiting plate 92. The setting of the spring 93 makes the spline shaft 91 need to apply a certain force to slide, increasing its stability when not stressed.

[0028] The edge-adjusting component 9 further includes a mounting frame 94 fixedly connected to the outer end of the spline shaft 91 located outside the bracket 82. A mounting hole 95 is formed in the outer wall of the mounting frame 94 close to the lower die table 1. A guide roller 96 is rotatably installed inside the mounting hole 95. A driving motor 97 is fixedly connected to the top surface of the mounting frame 94. The output shaft of the driving motor 97 is coaxially and fixedly connected to the rotating shaft of the guide roller 96. By driving the guide roller 96 to rotate through the driving motor 97, the steel plate 2 can be translated to one side.

[0029] Specifically, when the calibration components 8 on both sides of the lower die table 1 return to the center and approach the steel plate 2, one side of the steel plate 2 enters between the two mounting frames 94, and the steel plate 2 slightly opens the two mounting frames 94 outward, and the spline shaft 91 slides outward with the movement of the mounting frames 94. At this time, the spring 93 is compressed, and under the elastic force of the spring 93, the guide roller 96 is tightly against the short side of the steel plate 2. When the pressure values ​​detected by the multiple pressure sensors 86 tend to be consistent, the calibration is completed. At this time, the electromagnetic valve 845 is opened, and the rodless chambers of the plunger cylinders 841 on both sides of the lower die table 1 are in a connected state. When welding or bolting requires different folding widths or the folding width needs to be adjusted due to limited installation space, the motor 97 is driven to open. The guide roller 96 is driven to rotate, and the guide roller 96 is against the short side of the steel plate 2, thereby driving the steel plate 2 to move to one side. During this process, the long side of one side of the steel plate 2 pushes the abutment plate 85 along the moving direction, and the abutment plate 85 pushes the piston 843 to move through the sliding rod 842, and part of the pressure oil in the rodless chamber of the plunger cylinder 841 is pressed into the rodless chamber of the plunger cylinder 841 on the other side through the pipeline. The piston 843 in the plunger cylinder 841 on the other side is pressurized and can push the sliding rod 842 and the abutment plate 85 connected thereto to extend in the moving direction of the steel plate 2, so that the abutment plates 85 on both sides move in the same direction, and the interval remains unchanged, thereby ensuring the stability of the posture of the steel plate 2 during the movement process and avoiding the deflection again during the movement; After the edge adjustment of one side of the steel plate 2 is completed, the second cylinder 40 drives the upper mold 50 to press down to fix the steel plate 2. At this time, the second folding assembly 30 bends the steel plate 2 upward, and then the second cylinder 40 drives the upper mold 50 to rise, and again uses the edge adjustment assembly 9 to make the steel plate 2 move in the opposite direction to adjust the folding distance on the other side of the steel plate 2. After the adjustment is completed, the second cylinder 40 drives the upper mold 50 to press down to fix the steel plate 2, and the steel plate 2 is bent downward through the first folding assembly 20 to complete the Z-shaped bending process of the steel plate 2.
