When the steel strip moves to the right to a set length, the electric cylinder 9 on the top of the open angle upper die 4 pushes the open angle upper die 4 to move downward. At this time, the protrusion at the bottom of the open angle upper die 4 will squeeze a V-shaped groove out of the steel strip, which is convenient for bending during subsequent processing;

[0029] An open-angle upper die 4 is arranged on the top of the open-angle lower die 5, and two electric cylinders 9 are fixedly connected to the top of the open-angle upper die 4, and the tops of the two electric cylinders 9 are fixedly connected to the main support 1 through a support frame; twelve groups of upper forming rollers 6 and lower forming rollers 7 are equidistantly installed on the right side of the open-angle lower die 5; the middle and front and rear ends of the lower forming roller 7 are thick rods, and a section of thin rods is arranged between the middle and the front and rear ends, so that the steel strip can be extruded into a W-shaped profile in cooperation with the upper forming roller 6; a punching knife 8 is also arranged on the right side of the top of the main support 1, and two electric cylinders 9 are also fixedly connected to the top of the punching knife 8, and the tops of the two electric cylinders 9 are also fixedly connected to the main support 1 through a support frame; a bending frame 10 is arranged on the right side of the main support 1; a group of lower clamping seats 12 are fixedly arranged on the right side of the top of the bending frame 10;

[0030] An upper clamping seat 11 is arranged above the lower clamping seat 12, and two electric cylinders 9 are also fixedly connected to the top of the upper clamping seat 11, and the tops of the two electric cylinders 9 are fixedly connected to the bending frame 10 through a support frame; a groove is arranged in the middle and front and rear ends of the upper clamping seat 11, and the lower clamping seat 12 is divided into three sections, which are respectively located below the middle groove of the upper clamping seat 11 and below the front and rear end grooves of the upper clamping seat 11. When clamping, the upper clamping seat 11 and the lower clamping seat 12 will fit perfectly with the shape of the steel belt to avoid squeezing and deforming the steel belt; a bending push block 13 is also supported by two electric cylinders 9 on the upper right side of the support plate at the bottom of the bending frame 10; the distance between the left side surface of the rectangular block below the bending push block 13 and the right side surfaces of the upper clamping seat 11 and the lower clamping seat 12 is 3 cm, thereby leaving a gap for the steel belt to be bent upward to a vertical state.

When bending, the semi-circular column on the top of the bending push block 13 will first contact the lower surface of the steel belt located on the right side of the upper clamping seat 11, and then the bending push block 13 continues to move upward to push this section of the steel belt to bend upward with the V-shaped groove below the right side of the upper clamping seat 11 as the base point, and the smooth surface on the top of the bending push block 13 during the bending process can prevent the steel belt from being squeezed and deformed.

[0032] Among them, a V-shaped strip protrusion is arranged in the middle position of the bottom of the opening angle upper die 4. When the steel strip moves to the right to the set length, the electric cylinder 9 on the top of the opening angle upper die 4 pushes the opening angle upper die 4 to move downward. At this time, the protrusion at the bottom of the opening angle upper die 4 will squeeze a V-shaped groove out of the steel strip, which is convenient for bending during subsequent processing.

When it is necessary to use this device to process the steel strip, first insert one end of the steel strip into the middle of the feed roller 2. At this time, the motor drives the feed roller 2 to rotate, which will cause the steel strip to move to the right. When the steel strip moves to the right to the set length, the open angle upper die The electric cylinder 9 at the top of the 4 pushes the open angle upper die 4 to move downward. At this time, the protrusion at the bottom of the open angle upper die 4 will squeeze a V-shaped groove on the steel strip, which is convenient for bending during subsequent processing. In this process, the right end of the steel strip will enter between the upper forming roller 6 and the lower forming roller 7. At this time, the upper forming roller 6 and the lower forming roller 7 squeeze it to deform the steel strip into a W-shaped profile. Then the steel strip continues to move to the right, and the steel strip will first pass through the bottom of the punching knife 8 and slide to the top of the bending frame 10. Then the steel strip will continue to pass through the bottom of the upper clamping seat 11. When the V-shaped groove on the steel strip just moves to the bottom of the right side of the upper clamping seat 11, the PLC controller will automatically The conveying of the steel belt to the right is paused, and the electric cylinder 9 on the top of the upper clamping seat 11 is controlled to push the upper clamping seat 11 to move downward to clamp the steel belt. When clamping, the upper clamping seat 11 and the lower clamping seat 12 will fit perfectly with the shape of the steel belt to avoid squeezing and deforming the steel belt. At the same time, the PLC controller will control the electric cylinder 9 at the bottom of the bending push block 13 to push the bending push block 13 to move upward. At this time, the semicircular column on the top of the bending push block 13 will first contact the lower surface of the steel belt on the right side of the upper clamping seat 11, and then the bending push block 13 will continue to move upward to push this section of the steel belt to bend upward with the V-shaped groove below the right side of the upper clamping seat 11 as the base point, and the bending During the folding process, the smooth surface on the top of the bending push block 13 can prevent the steel strip from being squeezed and deformed. When the bending push block 13 moves to the top, the steel strip will also bend to a vertical state, and then the bending push block 13 will be lowered, and the upper clamping seat 11 will be raised. The motor will continue to drive the feed roller 2 to rotate and push the steel strip to move to the right, and then continue to groove and bend the steel strip according to the above process. When the steel strip is bent into a rectangular structure, the electric cylinder 9 on the top of the punching knife 8 will push the punching knife 8 to move downward to cut off the steel strip, thereby forming a rectangular frame, and then continue to repeat the above actions until the specified number is reached and then continue to set the PLC to complete the next specification of steel strip.
