Description

Technical Field

[0001] The invention relates to the technical field of wheel hub processing, in particular to a material turning mechanism of a band saw machine for wheel hub processing. Background Art

[0002] The production process of forged wheel hub is to first cut the wheel hub raw material to a fixed size on a band saw, and then process the blank into a wheel hub through processes such as preheating, shorting, and forming forging.

[0003] After the wheel hub raw material is cut by the band saw, the blank is in a vertical state. Since the raw material is a cylindrical aluminum rod, the vertical state of the cut blank is not convenient for transportation, and it may roll during transportation. Therefore, the blank needs to be turned over to make it horizontal. The traditional turning method is mostly done manually. Since the blank is heavy and the edges and corners are sharp after cutting, manual turning is more dangerous, which brings certain adverse effects to people's use process.

[0015] Beneficial Effects

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. In the present invention, the position of the baffle is adjusted before loading, so that the spacing between the baffle and the band saw machine is the required length of the hub blank, and then one end of the hub raw material is transported to the upper end of the rolling roller and contacts the surface of the rolling roller and continues to be transported forward until one end of the hub raw material is against the two baffles, and then the first cylinder pushes the first moving block to move, at this time the clamping pliers will cooperate with the other one to tightly clamp the hub raw material with the movement of the first moving block to complete the clamping and fixing of the hub raw material, and then the two second cylinders are controlled at the same time to drive the two first connecting plates to move downward, and the band saw machine is turned on at the same time, and the band saw machine will move downward together with the movement of the two first connecting plates, and the band saw moved to the band saw machine After contacting the hub raw material, it continues to move downward to cut the hub raw material, and the hub raw material can be prevented from rolling during cutting under the tight clamping of the two clamping pliers, thereby improving the stability of cutting the hub raw material.

[0018] 2. In the present invention, after the wheel hub raw material is cut, a clamping block is pushed by the fourth cylinder to cooperate with another clamping block to clamp the cut blank, and then the first cylinder drives the first moving block and a clamping clamp to retract backward to cancel the clamping of the raw material, and then the first motor drives the screw rod to rotate. At this time, the second moving block will drive the first connecting block to move forward with the rotation of the screw rod, and at the same time drive the connecting box, the movable plate and the wheel hub blank on the upper end of the movable plate to move, which can conveniently drive the cut blank to move, so as to facilitate the subsequent turning process. At the same time, under the action of the clamping block, the blank can be clamped when it is driven to move, so as to prevent the blank from slipping from the upper end of the movable plate during movement.

[0019] 3. In the present invention, after the blank is moved to a suitable position, the two third cylinders are controlled to simultaneously push the second connecting block to move. Since the second connecting block is movably connected to the second fixed seat through the second connecting shaft, the second fixed seat is welded to the bottom of the movable plate, and the movable plate and the connecting box are movably connected through the hinge, when the third cylinder pushes the second connecting block to move, the second fixed seat will drive the movable plate to flip over until the movable plate and the connecting box are in a vertical state. When the movable plate flips over, it will also drive the wheel hub blank to flip over, so that the wheel hub blank is turned to a horizontal state. At the same time, the two baffles will be inserted into the rectangular groove opened at the upper end of the movable plate after the movable plate is flipped, so that the wheel hub blank can be stably placed on the upper end of the movable plate in a horizontal state after flipping. Here, under the action of the two clamping blocks, the wheel hub blank can be prevented from falling off when the wheel hub blank is turned over.

[0020] 4. In the present invention, after the wheel hub blank is turned over, a clamping block is driven by the fourth cylinder to move and cancel the clamping of the wheel hub blank, and then the first motor drives the connecting box and the movable plate to move to the original position for turning over again. When the movable plate moves, the two baffles will be pulled out of the rectangular groove. After the baffles are pulled out, the movable plate is flipped over to a horizontal state with the connecting box by the third cylinder. The blank material will stay on the upper end of the movable plate after the baffles are pulled out. At this time, the two second motors simultaneously drive the two gears to rotate. Here, the two second motors rotate in opposite directions. When the two gears rotate at the same time, the movable plate will move forward under the action of the two racks. After moving to the guide plate just above the conveyor belt, the moving plate is stopped, and then the two fifth cylinders push the push plate to move. When moving, the push plate will push the wheel hub blank on the upper end of the movable plate to move. After the wheel hub blank moves to the guide plate, it will slide down to the upper end of the conveyor belt under the guidance of the guide plate, and the conveyor belt driven by the third motor will be transported to the next process for processing.

DETAILED DESCRIPTION

[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0031] like Figure 1As shown, after the hub raw material is conveyed to the upper end of the rolling roller 3, it is further conveyed forward between the two clamping clamps 7. The first cylinder 5 pushes the first moving block 6 and a clamping clamp 7 to move so that the two clamping clamps 7 can clamp the hub raw material tightly. Then, the second cylinder 8 drives the first connecting plate 9 and the band saw 10 to descend so that the hub raw material can be cut. After the cutting is completed, the fourth cylinder 30 pushes the clamping block 31 to move so that the two clamping blocks 31 clamp the cut hub blank. Then, the first cylinder 5 drives the first moving block 6 and the clamping clamp 7 to move to cancel the clamping of the hub raw material. Then, the first motor 13 can be turned on to drive the blank on the upper end of the connecting box 18 and the movable plate 19 to move forward. After moving to the front end, the movable plate 19 is flipped to make the hub blank The material is turned over to the upper end of the movable plate 34 in a horizontal state, and then the clamping block 31 is pulled by the fourth cylinder 30 to cancel the clamping of the hub blank. The connecting box 18 and the movable plate 19 are driven to move to the original position by reversing the first motor 13. At this time, the hub blank will stay on the upper end of the movable plate 34. At this time, the two second motors 40 simultaneously drive the two gears 41 to rotate, and under the action of the rack 38, the movable plate 34 and the hub blank on its upper end will be driven forward. After moving to the guide plate 46 being directly above the conveying platform 47, the push plate 45 is pushed to move by the fifth cylinder 44. When moving, the push plate 45 will push the hub blank to the guide plate 46 and then slide down to the upper end of the conveyor belt 48 in the conveying platform 47 under the guidance of the guide plate 46 for transportation.

[0032] like Figure 2 As shown, the wheel hub is originally conveyed to the upper end of the rolling roller 3 and then continues to be conveyed forward to move between the two clamps 7. Then, the first cylinder 5 pushes the first moving block 6 to move, which can drive a clamp 7 to move, so that the two clamps 7 can tightly clamp the wheel hub raw material. Then, the second cylinder 8 drives the first connecting plate 9 and the band saw 10 to move downward to cut the wheel hub blank.

[0033] like Figure 3-Figure 4 As shown, the output end of the first motor 13 is connected to a screw rod 14, and the screw rod 14 and the outer surface of the fixed rod 15 are respectively threadedly connected and slidably connected with a second moving block 16, and a first connecting block 17 is welded to the upper end of the second moving block 16, and a connecting box 18 is welded between the two first connecting blocks 17. When the first motor 13 drives the screw rod 14 to rotate, the second moving block 16 will drive the first connecting block 17 and the connecting box 18 to move with the rotation of the screw rod 14, and at the same time, it will drive the movable plate 19 and the wheel hub blank at its upper end to move. Before moving, the clamping block 31 is pushed to move by the fourth cylinder 30, so that the two clamping blocks 31 clamp the wheel hub blank to prevent the wheel hub blank from slipping during movement, and at the same time, it can prevent the wheel hub blank from falling from the upper end of the movable plate 19 when the wheel hub blank is turned over.

[0034] like Figure 5 As shown, two first fixed seats 21 are welded in the connecting box 18, and a movable block 22 is movably connected in the first fixed seat 21 through a first connecting shaft 23. A third cylinder 24 is welded at one end of the movable block 22, and a second connecting block 25 is welded at the output end of the third cylinder 24. When the third cylinder 24 pushes the second connecting block 25 to move, since the second connecting block 25 is movably connected to the second fixed seat 26 through the second connecting shaft 27, the second fixed seat 26 is welded to the bottom of the movable plate 19, and the movable plate 19 is movably connected to the connecting box 18 through a hinge 20. Therefore, when the third cylinder 24 pushes the second connecting block 25 to move, the second fixed seat 26 will drive the movable plate 19 to flip to be perpendicular to the connecting box 18, thereby driving the wheel hub blank at the upper end of the movable plate 19 to be turned over.

[0035] like Figure 6-Figure 7 As shown, track grooves 33 are provided on both sides of the support frame 32, and a movable plate 34 is arranged above the support frame 32. Racks 38 are welded to the inner surfaces of both sides of the support frame 32, and two support plates 39 are welded to the front end of the movable plate 34. The upper end of the support plate 39 is detachably connected to the second motor 40, and the output end of the second motor 40 passes through the support plate 39 and is connected to a gear 41. When the two second motors 40 drive the two gears 41 to rotate, the movable plate 34 will be driven to move forward under the action of the two racks 38. When the movable plate 34 moves, the two sets of track wheels 37 will slide horizontally in the two track grooves 33 respectively, so that the movable plate 34 moves more smoothly. At the same time, when the movable plate 34 moves, it will drive the wheel hub blank at its upper end to move. After moving to the guide plate 46 and being located just above the conveying platform 47, the wheel hub blank above the movable plate 34 can be pushed to be unloaded onto the conveying platform 47 for conveying.

[0036] like Figure 8 As shown, a second vertical plate 43 is welded to the upper end of the movable plate 34, and two fifth cylinders 44 are detachably connected to one side of the second vertical plate 43. The fifth cylinders 44 can push the pushing plate 45 to push the hub blank on the upper end of the movable plate 34 to the guide plate 46 to unload it onto the conveying platform 47 for conveying.

[0037] It should be noted that the present invention is a turning mechanism of a band saw machine for wheel hub processing. When in use, the first motor 13 is turned on to drive the screw rod 14 to rotate, thereby driving the second moving block 16 and the first connecting block 17 to move. When the first connecting block 17 moves, it will drive the connecting box 18 and the movable plate 19 to move, and at the same time, it can drive the baffle 28 to move. After moving to the distance between the baffle 28 and the band saw machine 10 to be the required length of the wheel hub blank, one end of the wheel hub raw material is conveyed to the rolling roller 3 and then continued to be conveyed forward until one end of the wheel hub raw material abuts against the baffle 28. Then, the first cylinder 5 pushes the first moving block 6 and a clamp 7 to move, so that the two clamps 7 tightly clamp the wheel hub raw material, and then the band saw machine 10 can be turned on. The first connecting plate 9 is driven downward by the second cylinder 8. When the first connecting plate 9 moves, it drives the band saw 10 to move downward to cut the hub raw material. After the cutting is completed, the first cylinder 5 drives the first moving block 6 and the clamping clamp 7 to cancel the clamping of the hub raw material, and then the fourth cylinder 30 drives a clamping block 31 to move, so that the two clamping blocks 31 clamp the hub blank, and then the first motor 13 drives the screw rod 14 to rotate. At this time, the second moving block 16 will drive the first connecting block 17 and the connecting box 18 to move forward with the rotation of the screw rod 14, and at the same time drive the movable plate 19 and the hub blank at its upper end to move. Here, under the clamping of the two clamping blocks 31, the hub blank can be prevented from slipping when moving. In this case, after the connecting box 18 moves to the front end, the second connecting block 25 is pushed to move by the two third cylinders 24. Since the second connecting block 25 is movably connected to the second fixing seat 26 by the second connecting shaft 27, and the second fixing seat 26 is welded to the bottom of the movable plate 19, and the movable plate 19 is movably connected to the connecting box 18 by the hinge 20, when the third cylinder 24 pushes the second connecting block 25 to move, the second fixing seat 26 will drive the movable plate 19 to flip until the movable plate 19 and the connecting box 18 are in a vertical state. When the movable plate 19 flips, it will drive the wheel hub blank at its upper end to be turned over. At the same time, when the movable plate 19 flips, the baffle 28 will flip into the rectangular groove 42 opened on the surface of the movable plate 34. After the wheel hub blank is turned over, the clamping block 31 is driven by the fourth cylinder 30 to cancel the clamping of the wheel hub blank, and then the connecting box 18 and the movable plate 19 are driven by the first motor 13 to move to the original position for the purpose of turning over again. When the movable plate 19 moves, the two baffles 28 are respectively drawn out from the two rectangular grooves 42. At this time, the wheel hub blank will stay on the upper end of the movable plate 34 in a horizontal state. At this time, the two second motors 40 simultaneously drive the two gears 41 to rotate. Under the action of the rack 38, the movable plate 34 will move forward, and at the same time, it will drive the wheel hub blank and the guide plate 46 to move. When moving, the two sets of track wheels 37 will slide forward horizontally in the two track grooves 33 respectively, so that the movement of the movable plate 34 is more stable.After the guide plate 46 is moved to the top of the conveyor belt 48, it stops moving. Then, the two fifth cylinders 44 push the push plate 45 to move. When the push plate 45 moves, it pushes the wheel hub blank on the upper end of the moving plate 34 to move. After moving to the guide plate 46, it slides down to the upper end of the conveyor belt 48 under the guidance of the guide plate 46. Then, the third motor 49 drives the conveyor belt 48 to transport the wheel hub blank to the next process for processing.

It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
