Description

Technical Field

The first pushing assembly includes a conveying platform, a fixed frame, a threaded rod, a first driving member and a threaded sleeve. The second pushing assembly includes a second driving member, a connecting rod and a push plate. When in use, the first driving member drives the threaded rod to rotate, the threaded rod drives the threaded sleeve to move, and the threaded sleeve then drives the second pushing assembly to move through the connecting rod, thereby pushing the plate to the processing platform of the punching and shearing machine, and then starting the second driving member, the piston rod of the second driving member extends, drives the push plate to move, and continues to push the plate to the processing position. This patent has a high degree of mechanization and high work efficiency.

The design of the U-shaped block 601 can realize that when the limiting wheel 603 drives the connecting rod 602 to slide inside the guide groove 15, the U-shaped block 601 can avoid the connecting rod 602.

The inner walls of the two U-shaped frames 702 are slidably provided with a support plate 705. Two through grooves are penetrated through the upper surface of the support plate 705. The inner walls of the two through grooves are rotatably provided with multiple electric rollers 706. Through the set electric rollers 706, when the steel on the support plate 705 is aligned with the shearing opening, the steel can be driven to achieve the shearing work. The electric rollers 706 are prior art and are widely used in various conveyor belt systems, such as automated production lines, logistics transportation systems, etc. The L-shaped steel 9 is set on the upper surface of the support plate 705.

[0040] A positioning groove 703 is provided on one side of the two U-shaped frames 702, and the inner walls of the two positioning grooves 703 are slidably connected with positioning blocks 704. The opposite surfaces of the two positioning blocks 704 are fixedly connected to the two sides of the support plate 705 respectively.

A plurality of springs 712 are fixedly connected to the upper surface of the cross plate 701, and the top ends of the plurality of springs 712 are fixedly connected to the lower surface of the support plate 705 respectively. Four springs 712 are provided to achieve the reset of the support plate 705 when it is not subjected to the pressure of the steel material.

[0041] The lower surface of the support plate 705 is fixedly connected with a pressure rod 707, and the surface of the pressure rod 707 is fixedly connected with a limit pin 708. The upper surface of the cross plate 701 is rotatably connected with a sleeve 710 through a bearing. The surface of the sleeve 710 is provided with an annular groove 711, and the surface of the sleeve 710 is fixedly connected with a rotating plate 709. By cooperating with the limit pin 708 on the pressure rod 707 and the annular groove 711 on the sleeve 710, the movement trajectory of the sleeve 710 can be changed to make it rotate. The rotating plate 709 is diamond-shaped.

[0042] like Figure 3 and Figure 4 As shown, the upper surface of the horizontal plate 701 is fixedly connected to two fixing frames 713, the inner walls of the two fixing frames 713 are fixedly connected to sliding rods 715, the surfaces of the two sliding rods 715 are slidably connected to sliding blocks 716, the lower surfaces of the two sliders 503 are rotatably connected to rotating rods 714, and the ends of the two rotating rods 714 away from the sliding blocks 716 are rotatably connected to the upper surface of the rotating plate 709 respectively.

[0043] The two sides of the two sliding blocks 716 are rotatably connected with a rotating rod 1 717, and the ends of the two rotating rods 1 717 away from the sliding blocks 716 are rotatably connected with rotating rods 2 718 respectively. The ends of the two rotating rods 2 718 away from the rotating rod 1 717 are rotatably connected to the upper surface of the fixed frame 713 through follower rods 719 respectively. The top ends of the two follower rods 719 are fixedly connected with a fixed plate 720. The upper surfaces of the two fixed plates 720 are penetrated with rotating holes, and the inner walls of the two rotating holes are rotatably connected with clamping rollers 721. The clamping rollers 721 are composed of two parts, and clamping rollers 721 are arranged on the upper and lower parts to increase the clamping range. The clamping rollers 721 are made of rubber material to avoid rigid clamping and increase friction. The relative rotation design between the clamping rollers 721 and the steel makes it convenient for the electric rollers 706 on the support plate 705 to drive the steel.

[0044] The specific working method is as follows: when in use, first place the L-shaped steel 9 or the U-shaped steel on the support plate 705, the support plate 705 is subjected to the pressure of the steel, the support plate 705 moves downward, the support plate 705 drives the pressure rod 707 to descend, the pressure rod 707 drives the limit pin 708 to slide in the annular groove 711 on the sleeve 710, and then the sleeve 710 is rotated. When the sleeve 710 rotates, it will drive the rotation of the rectangular plate, and the rotation of the rectangular plate will drive the rotation of the two rotating rods 714, thereby pulling the two sliding blocks 716 on the sliding rod 715. The sliding of the two sliding blocks 716 will drive the rotation of the two rotating rods 1 717, and the rotation of the two rotating rods 1 717 will drive the rotation of the two rotating rods 2 718. Through the rotation relationship between the two rotating rods 1 717 and the two rotating rods 2 718, the two follower rods 719 can drive the rotation of the two fixed plates 720, and the movement of the two fixed plates 720 can drive the two sets of clamping rollers 721 to rotate, so that the steel placed on the support plate 705 can be centered at the four corners to achieve positioning during the feeding process, thereby improving the accuracy of feeding;

[0045] During the positioning process, the support plate 705 is subjected to gravity to fall, so that the steel material can be aligned with the shearing opening on the machine body 1. After positioning and clamping, the motor 12 is started, and the motor 12 drives the threaded rod 11 to rotate, so that the feeding work can be realized. The threaded rod 11 rotates to realize the sliding of the U-shaped block 601. The U-shaped block 601 drives the connecting rod 602 and the limiting wheel 603 to slide inside the moving groove 13, thereby driving the steel material to move. During the movement of the steel material, if the L-shaped steel material 9 is placed on the support plate 705, the steel material will squeeze the roller 506 in the right reversing component 5 (reference Figure 1 , the position of the body 1 is north), the roller 506 is squeezed and then squeezes the spring 1 505, so that the rack 1 504 moves, and the movement of the rack 1 504 drives the gear 508 to rotate, and the rotation of the gear 508 drives the rack 2 510 to move away from the rack 1 504. Therefore, the movement of the rack 2 510 drives the vertical rod 509 and the moving block 513 to move on the inner wall of the limiting groove 511 through the limiting block 512, and the movement of the moving block 513 drives the spherical rod 514 moves, the spherical rod 514 moves to the top of the guide groove 2 15, thereby blocking the moving ball 604. After the spherical rod 514 blocks the ball 604, it will drive the limiting wheel 603 to deviate from the guide groove 2 15 and slide toward the guide groove 1 14, thereby realizing that the L-shaped steel 9 is aligned with the L-shaped shearing opening 2 on the machine body 1. At this time, the electric roller 706 on the support plate 705 drives the L-shaped steel 9 to be inserted into the L-shaped shearing opening 2 on the machine body 1 for punching and shearing.

[0046] If a U-shaped steel is placed on the support plate 705, the U-shaped steel will squeeze the roller 506 in the left reversing assembly 5 (refer to Figure 1, the position of the machine body 1 is north), repeat the above steps, the limiting wheel 603 deviates from the guide groove 14 and slides toward the guide groove 2 15, thereby realizing that the U-shaped steel is aligned with the U-shaped shearing opening 3 on the machine body 1. At this time, the U-shaped steel is driven by the electric roller 706 on the support plate 705 to insert into the U-shaped shearing opening 3 on the machine body 1 for punching and shearing, which further improves the accuracy and adaptability of feeding.
