Description

Technical Field

[0001] This utility model relates to the field of angle steel processing technology, specifically to a feeding device for angle steel. Background Technology

[0002] In fields such as building structures and iron tower manufacturing, the feeding process in angle steel slitting is the core link between raw material storage and cutting operations. Traditional feeding methods are no longer suitable for the needs of modern mass production, and there are significant shortcomings in automation and connectivity. Current processing relies heavily on manual labor to separate, align, and transfer angle steel from stacking racks to shelving racks. Even with simple conveying equipment, manual assistance is still required for the transfer, making it impossible to achieve automatic transfer from stacking racks to shelving racks. This results in high labor intensity and low efficiency. At the same time, the pushing and positioning of angle steel to the cutting station also requires manual positioning and pushing. The lack of a reliable clamping structure can cause the angle steel to shift and sway, thus affecting subsequent slitting. Utility Model Content

[0003] To achieve the above objectives, this utility model provides the following technical solution: a feeding device for angle steel, comprising a frame, the frame being divided into a stacking area, a transfer area, and a cutting area. The stacking area of ​​the frame has a downward slope, and multiple inclined L-shaped plates and guide plates are fixed below the slope, as well as multiple sets of pushing assemblies corresponding to the guide plates. The pushing end of the pushing assembly is fixed with an inclined block that has the same inclination angle as the guide plate and is connected to it. The transfer area of ​​the frame is equipped with a push clamp assembly and a traveling assembly. A slide rail slider is installed on the transfer area, and a push plate driven to move by the traveling assembly is installed on the slider of the slide rail slider.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4This embodiment of an angle steel feeding device includes a frame 1, which is divided into a stacking area, a transfer area, and a cutting area along the angle steel conveying direction. Each area works together to realize automatic feeding, pushing, and cutting of angle steel. The stacking area of ​​the frame 1 forms a downward slope, using the weight of the angle steel to achieve initial material feeding guidance. At least four inclined L-shaped plates 2 and guide plates 3 are fixed below the slope. The L-shaped plates 2 are used to receive angle steel that slides down from the stacking area and restrict its placement posture. The guide plates 3 provide a guiding path for the angle steel to be conveyed to the transfer area. The stacking area is also equipped with four sets of pushing components that correspond one-to-one with the guide plates 3. The pushing end of the pushing component is fixed with an inclined block 9. The inclined block 9 has the same inclination angle as the guide plate 3 and can be connected to ensure that the angle steel can smoothly transition to the guide plate along the inclined block.

[0019] Among them, such as Figure 2 The jacking assembly includes four sets of support plates 6 fixed on the frame 1. A jacking cylinder 7 is vertically installed on the support plate 6. A jacking block 8 is fixed to the top of the piston rod of the jacking cylinder 7. The inclined block 9 is fixed to the top end face of the jacking block 8. The jacking block can be moved upward by the jacking cylinder, thereby causing the single angle steel to separate from the L-shaped plate. The angle steel is then transferred to the transfer area by the inclined block and the guide plate. In order to improve the stability of the jacking block lifting and lowering, four pairs of rails 4 are fixed on the frame 1 at the stacking area. Each pair of rails 4 is distributed on both sides of the corresponding jacking block 8. Pulleys 5 are installed on both sides of the jacking block 8. The pulleys 5 are embedded in the corresponding rails 4 and can slide along the rails 4.

[0020] like Figure 3 The transfer area of ​​the frame 1 is equipped with a push clamp assembly for clamping angle steel, a walking assembly for driving the angle steel to move, and a guide rail slider 14. The slide rail of the slide rail slider 14 is fixed to the top surface of the frame transfer area. A push plate 15 is installed on the slider of the slide rail slider. The push plate 15 is driven by the walking assembly to move along the length of the slide rail, thereby moving the angle steel to the cutting area.

[0021] The push-clamp assembly includes two sets of push cylinders 10. The push cylinders 10 are horizontally installed at the bottom of the frame 1 in the transfer area. A crossbar is fixed between the piston rods of the push cylinders. The crossbar is in sliding fit with the top of the transfer area. No fewer than eight protruding plates 12 are fixed on the top of the crossbar. The protruding plates 12 are arranged opposite to the slide rail of the slide rail slider 14, and the height of the slide rail is higher than the height of the protruding plates 12, so as to ensure that when the protruding plates push the angle steel, they cooperate with the slide rail to clamp the angle steel.

[0022] In addition, the walking assembly includes a mounting plate 16, which is fixed to the top of the push plate 15 by bolts through a waist hole. A motor 17 is mounted on the back of the mounting plate 16, and a gear 18 is fixed to the drive shaft of the motor 17. A rack 13 is fixed to the back of the frame 1 located in the transfer area. The rack 13 meshes with the gear 18. The motor drives the gear to rotate along the rack, thereby driving the push plate to move along the slide rail, thus realizing the pushing of the angle steel to the cutting area. The setting and adjustment of the waist hole allows the push plate to be positioned on the slide rail slider, thereby adjusting the position of the push plate.

[0023] like Figure 4 A slitting assembly is installed on the slitting area of ​​the frame 1. The slitting assembly includes a slitting frame with a slope. A screw device 20 is installed on the slope. A moving plate 21 is fixed to the nut end of the screw device 20. The moving plate is in sliding fit with the slope surface of the slitting frame. A slitting device is installed on the moving plate. The screw device drives the moving plate to move the slitting device along the slope, thereby realizing the adjustment of the slitting position and the feeding coordination.

[0024] The working principle of the above embodiments is as follows:

[0025] The stacking area slopes downwards. Angle steel relies on its own weight for initial unloading guidance, sliding down to the L-shaped plate and positioned above the inclined block. The L-shaped plate restricts the angle steel's placement, while the guide plate has a pre-set conveying path. When the loading program starts, the four sets of pushing components in the stacking area work synchronously. Pushing cylinders drive the pushing blocks upwards, and pulleys on both sides of the pushing blocks slide along the rails, ensuring stability during the lifting process. The inclined block at the top of the pushing block has the same tilt angle as the guide plate and precisely aligns. During the upward movement of the pushing block, the inclined block lifts a single angle steel and separates it from the L-shaped plate. The angle steel then smoothly transitions along the inclined block to the guide plate, and with the guide plate's guidance, enters the transfer area, completing the automatic separation and loading of single angle steel. The transfer area, through the cooperation of the push clamp assembly, the traveling assembly, and the slide rail slider, achieves the directional transfer of angle steel to the cutting area. First, the push clamp assembly starts, and two sets of pushing cylinders drive the crossbar to move laterally. The convex plate at the top of the crossbar simultaneously pushes the angle steel. At this time, the slide rail slides... Because the slide rail of the block is higher than the convex plate, it forms a clamping structure opposite to the convex plate, ensuring the transfer and clamping of the angle steel. Then the walking component starts to work. The motor drives the gear to rotate along the rack on the back of the frame. Through the meshing transmission of the gear and rack, the push plate with the mounting plate fixed on it is driven to slide along the slide rail. The position of the push plate can be adjusted through the waist hole of the mounting plate. After the convex plate is separated from the angle steel, the push plate accurately pushes the angle steel and moves it smoothly to the cutting area. The cutting component in the cutting area drives the cutting device to move through the screw device to achieve precise cutting of the angle steel. The cutting frame is set at a slope. The screw device is installed on the slope. The moving plate connected to its nut end slides with the surface of the cutting frame. Before processing, the screw device drives the moving plate to move the cutting device along the slope to complete the precise adjustment of the cutting position. During processing, the screw device continues to drive the moving plate to feed, so that the cutting device cuts the angle steel transferred here according to the preset path, and finally completes the automated cutting process of the angle steel.
