Description

Technical Field

[0001] This invention relates to the field of angle steel processing technology, specifically a large angle steel double-end blanking tool. Background Technology

[0002] When drilling angle steel, some angle steels require manual placement on a workbench, securing with clamps, and controlling the drilling machine's feed to drill holes. After drilling, the angle steel is moved and collected for later use. Angle steels typically require hole-aligning processing, where multiple symmetrical through holes are machined on both sides of the angle steel's flanges. Current technology generally involves manually changing the drilling machine's feed direction to drill holes on both flanges separately. This method increases the labor intensity of workers and undoubtedly reduces work efficiency. Regarding angle steel processing positioning, patent publication number CN113732355B discloses an angle steel hole-aligning processing device. This device uses positioning seats on two sets of conveyor belts, combined with a clamping mechanism, to clamp and position the upper and lower ends of the angle steel. However, this positioning method tightly presses and fixes the upper and lower surfaces of the angle steel, easily covering the drilling position, which is detrimental to drilling. Furthermore, the width between the two conveyor belts is not adjustable, which is unfavorable for processing angle steels of different lengths. Based on this, a large angle steel double-end unloading tooling is now provided, which can eliminate the drawbacks of existing devices. Summary of the Invention

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] In one embodiment, such as Figures 1-6As shown, a large angle steel double-end unloading fixture includes a base 11 and sliding seats 12 disposed on both sides of its upper end. The two sliding seats 12 are connected to a distance adjustment component for moving them closer or further apart. The distance between the two sliding seats 12 can be adjusted by the adjustment component to position angle steel of different lengths. Each sliding seat 12 has a support leg 15 at both ends. The upper end of the support leg 15 is provided with a transmission roller 17 rotatably connected to it via a transmission shaft 16. The transmission shaft 16 is connected to a transmission motor for driving its rotation. Here, the transmission motor is a synchronous motor. The two transmission rollers 17 above each sliding seat 12 are connected by a transmission belt 19. Each transmission belt 19 is provided with multiple positioning components arranged at equal intervals. The two sets of positioning components constitute a positioning fixture that cooperates with the two ends of the angle steel. In this way, the two ends of the angle steel 26 can be positioned to adapt to the feeding of different angle steels. The base 11 is also provided with a drilling component that cooperates with the angle steel 26. The drilling component can be used to drill holes in the surface of the angle steel.

[0026] The positioning component includes a support block 27 disposed on the conveyor belt 19. A support plate 37 is provided on one side of the support block 27, and a clamping gap is formed between the support plate 37 and the support block 27. A sliding cavity 30 is provided inside the support block 27. A pressing slide rod 36 is provided on the side of the support plate 37 facing the support block 27. The pressing slide rod 36 slides through a perforation on the surface of the sliding cavity 30. A trapezoidal block 28 is slidably disposed inside the sliding cavity 30. The left side of the trapezoidal block 28 is connected to the inner wall of the sliding cavity 30 through a first spring 29. The trapezoidal block 28 is connected to a pusher for driving it to slide in the sliding cavity 30. The pusher allows the support plate 37 and the support block 27 to cooperate to clamp and fix the two ends of the angle steel 26.

[0027] Above the sliding seat 12, there is also a guide support assembly for guiding the support block 27. The guide support assembly includes a support plate 18. The upper end of the support plate 18 is slidably disposed with the bottom of the support block 27 above. The two ends of the support plate 18 are connected and fixed to the support leg 15 through the connecting frame. The upper end of the support plate 18 has a plurality of spherical grooves, and a rolling ball is provided in each spherical groove. In this way, the sliding friction between the support block 27 and the support plate 18 can be converted into rolling friction, reducing the wear of the parts.

[0028] Figure 5As shown, the pushing component includes a pushing through hole on the side of the support block 27, the interface of which is rectangular; a transmission push rod 34 is slidably disposed in the pushing through hole, and a second pressure roller 35 is rotatably disposed at the inner end of the transmission push rod 34. The second pressure roller 35 cooperates with the inclined surface of the trapezoidal block 28, and a first pressure roller 33 is rotatably disposed at the outer end of the transmission push rod 34. The reset block 32 on the surface of the transmission push rod 34 is connected and fixed to the support block 27 by a second spring 31. Under the action of the second spring 31, the second pressure roller 33... 5. No thrust is generated on the inclined surface of trapezoidal block 28. A guide side plate is provided on both sides of the conveyor belt 19. The guide side plate is connected and fixed to the sliding seat 12 through the positioning column. When the stop support block 27 moves to the position of the guide side plate with the conveyor belt 19, the first pressure roller 33 will be pushed by the guide side plate, so that the transmission push rod 34 slides towards the inside of the sliding cavity 30. The second pressure roller 35 at the end of the transmission push rod 34 will generate a pushing force on the inclined surface of trapezoidal block 28, so that the support plate 37 moves closer to the surface of the support block 27 to complete the pressing action.

[0029] The pressing surfaces of the tray 37 and the support block 27 are provided with anti-slip pads, which can further improve the clamping effect;

[0030] The drilling component includes two lifting support columns 25 symmetrically arranged on the upper end of the base 11. The output ends of the two lifting support columns 25 are mounted on a horizontal seat, which is perpendicular to the conveyor belt 19. A drilling base 21 is slidably mounted on the horizontal plate. A drilling motor 22 is mounted on the drilling base 21. The output end of the drilling motor 22 is equipped with a drill bit 20 for drilling holes in the surface of the angle steel 26. A displacement screw hole is provided on the side of the drilling base 21. A displacement screw 23 is fitted in the displacement screw hole. One end of the displacement screw 23 is rotatably connected to a fixed block on the horizontal seat. The other end of the displacement screw 23 is connected and fixed to the output end of the displacement motor 24. In this way, the displacement motor 24 drives the displacement screw 23 to rotate relative to the drilling base 21. Under the action of the screw, the drilling base 21 can slide on the surface of the horizontal seat, thereby adjusting the drilling position.

[0031] The distance adjustment component includes an adjustment screw hole located in the middle of the sliding seat 12. An adjustment screw 14 is fitted in the adjustment screw hole. One end of the adjustment screw 14 is rotatably connected to the fixed block at the upper end of the base 11, and the other end is connected to an adjustment motor 13 for driving its rotation. The adjustment motor 13 drives the adjustment screw 14 to rotate relative to the sliding seat 12. Under the action of the screw, the sliding seat 12 slides along the upper end of the base 11, thereby adjusting the distance between the two sliding seats 12.

[0032] Figure 6As shown, the upper end of the base 11 is also provided with two guide rods, and the lower end of the sliding seat 12 is provided with a guide groove that cooperates with the guide rods. The cooperation between the guide rods and the guide groove makes the sliding seat 12 slide more smoothly.

[0033] The above embodiment discloses a large angle steel double-end unloading fixture. In actual use, the distance between the two sliding seats 12 is adjusted according to the different lengths of angle steel 26. The adjusting motor 13 drives the adjusting screw 14 to rotate relative to the sliding seat 12. Under the action of the screw, the sliding seat 12 slides along the upper end of the base 11, thereby adjusting the distance between the two sliding seats 12. Then, the corresponding angle steel 26 is fixed between the two support blocks 27. Initially, the angle steel 26 is only stuck. When the support block 27 moves to the processing position with the conveyor belt 19, the first pressure roller 33 will be pushed by the guide side plate, thereby making the transmission push The rod 34 slides towards the inside of the sliding cavity 30. The second pressure roller 35 at the end of the transmission push rod 34 will generate a pushing force on the inclined surface of the trapezoidal block 28, thereby causing the pallet 37 to move closer to the surface of the support block 27 to complete the pressing action and ensure the stability of the processing. In addition, when it leaves the processing position, the pallet 37 will separate from the support block 27 when the guiding side plate is no longer in use, thereby releasing the angle steel 26. As the conveyor belt 19 continues to rotate, the support block 27 will be in an inverted state. At this time, the angle steel 26 will detach from the upper end of the support block 27, thereby completing the unloading. A collection conveyor belt is provided at the end of the conveyor belt 19 to promptly send away the processed angle steel 26.

[0034] The above description is merely a specific embodiment of this disclosure, but the scope of protection of this disclosure is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this disclosure should be included within the scope of protection of this disclosure. Therefore, the scope of protection of this disclosure should be determined by the scope of the claims.
