Description

Technical Field

[0001] This utility model relates to the field of aluminum rod processing technology, and in particular to an automatic aluminum rod sawing machine. Background Technology

[0002] Molten aluminum at high temperatures is cast into aluminum rods of different diameters using a casting machine. However, the aluminum profiles we see in daily life are basically made by extruding aluminum rods under high temperature and pressure. As aluminum is used more and more widely in industries such as automobiles, home appliances, construction, and aviation, the demand for aluminum rods is increasing.

[0003] Before aluminum bars can be sold, they need to be sawed to a specified length. Traditional aluminum bar sawing is still done by manual hoisting or forklift handling, which has a low degree of automation. The entire production process requires at least 15 people per shift to complete. Forklift stacking is dangerous and the manufacturing cost is very high.

[0004] Therefore, we designed an automatic aluminum rod sawing machine. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this utility model discloses an automatic aluminum rod sawing machine.

[0006] To achieve the above-mentioned objectives, the present invention adopts the following technical solution:

[0007] An automatic aluminum rod sawing machine includes a sawing device. The sawing device has a feeding conveyor on one side and a discharging conveyor on the other side. The discharging conveyor has extensions on both sides of its tail end, and a length-fixing device is provided between the extensions.

[0008] The length-fixing device includes two linear slide rails located on the inner side of corresponding extensions along the conveying direction of the unloading conveyor. Each of the two linear slide rails has an end beam at its end in the same direction, and an adjusting screw is rotatably connected between the two end beams. A sliding frame is slidably connected to the top of the two linear slide rails, and a screw nut that cooperates with the adjusting screw is provided at the bottom of the sliding frame. The top of the sliding frame is provided with rollers and positioning baffles at intervals along its moving direction, and the positioning baffles are located on the side of the rollers away from the sawing device, and the top of the rollers is on the same plane as the top of the conveying part of the unloading conveyor.

[0009] Preferably, the top of the sliding frame is provided with two rollers spaced apart on the side of the positioning baffle corresponding to the sawing device.

[0010] Preferably, a storage device is provided on one side of the feeding conveyor, corresponding to the position between the sawing device and the length-cutting device, and a transfer device is provided at the connection between the storage device and the feeding conveyor to facilitate the transfer of the cut aluminum rod from the feeding conveyor to the storage device.

[0011] Preferably, the storage device includes at least two support beams spaced apart along the conveying direction of the feeding conveyor, and the outer ends of the support beams are provided with stop structures.

[0012] Preferably, the height of the top surface of the support beam gradually decreases from the inner end to the outer end.

[0013] Preferably, the stop structure includes a stop frame with one end rotatably connected to the outer end of the support beam, and the other end of the stop frame is provided with an upwardly extending stop portion;

[0014] The gear shift structure also includes a first telescopic device for driving the gear shift bracket to flip.

[0015] Preferably, the transfer device includes a transfer frame with one end hinged to the inner end of the storage device, and the other end of the transfer frame extends beyond the side of the corresponding unloading conveyor and extends to the top of the conveying section of the unloading conveyor.

[0016] The transfer device also includes a second telescopic device for driving the transfer frame to flip, so as to lift the aluminum rod on the unloading conveyor and roll it to the top of the storage device under the guidance of the transfer frame.

[0017] Preferably, the position of the transfer frame located above the side of the unloading conveyor device and the position located below the top of the unloading conveyor device's conveying section have a smooth transition.

[0018] By adopting the technical solution described above, this utility model has the following beneficial effects:

[0019] 1. It can transport aluminum bars through the feeding and unloading conveying devices, and adjust the rotation of the lead screw to drive the lead screw nut to rotate, which in turn drives the sliding frame and positioning baffle to rotate, thereby realizing the function of adjusting the cutting length of the aluminum bars; the setting of the idler roller can effectively support the outer end of the aluminum bars, preventing the outer end of the aluminum bars from deforming downwards due to being too far away from the conveying part of the unloading conveying device, thus affecting the cutting accuracy.

[0020] 2. The length-fixing device is located inside the material feeding and conveying device, and should not occupy space in other parts of the workshop, making the structure more compact and solving the workshop space problem;

[0021] 3. The transfer device is designed so that the transfer frame is rotated by the extension and retraction of the second telescopic device, and the aluminum rod rolls to the storage device by its own weight. Compared with the transfer device that raises the aluminum rod vertically, transfers the aluminum rod horizontally, and lowers the aluminum rod vertically, the structure is simpler and requires less power equipment.

[0028] The present invention will be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention. In the description of the present invention, it should be understood that if terms such as "upper", "lower", "front", "rear", "left", "right" indicate orientation or positional relationship, they are only corresponding to the drawings of this application for the convenience of describing the present invention. It should be understood that if terms such as "end", "side", "end portion", "side part", "lateral", "longitudinal", etc. indicate orientation or positional relationship, they are only corresponding to the length and width of the corresponding component. That is, "end" indicates the head and tail area in the length direction of the corresponding component, and "side part" indicates the head and tail area in the width direction of the corresponding component. These are for the convenience of describing the present invention and do not indicate or imply that the device or element referred to must have a specific orientation.

[0029] Example 1, in conjunction with Appendix Figure 1 An automatic aluminum rod sawing machine includes a sawing device 1, a feeding conveying device 2 on one side of the sawing device 1 and a discharging conveying device 3 on the other side; as needed, the conveying part of the conveying device is a conveying roller; preferably, the conveying roller body can be provided with an annular groove, which radially positions the conveyed aluminum rod to ensure that the aluminum rod does not deviate; furthermore, in order to increase the conveying capacity at one time, multiple annular grooves can be provided at intervals along the axial direction of the conveying roller.

[0030] The material conveying device 3 has extensions 31 on both sides of its tail end, and a length-fixing device 4 is provided between the extensions 31.

[0031] Combined with appendix Figure 3 The length-fixing device 4 includes two linear slide rails 41 respectively located inside the corresponding extension 31 along the conveying direction of the unloading conveying device 3. The ends of the two linear slide rails 41 in the same direction are provided with end beams 42, and the two end beams 42 are rotatably connected to an adjusting screw 43. The top of the two linear slide rails 41 is slidably connected to a sliding frame 44, and the bottom of the sliding frame 44 is provided with a screw nut (not shown in the figure) that cooperates with the adjusting screw 43. The top of the sliding frame 44 is provided with rollers 45 and positioning baffles 46 at intervals along its moving direction. The positioning baffles 46 are located on the side of the rollers 45 away from the sawing device 1, and the top of the rollers 45 is on the same plane as the top of the conveying part of the unloading conveying device 3.

[0032] Depending on the needs, the end of the adjusting screw 43 may be equipped with a handwheel, which can be used to rotate the adjusting screw 43; or it may be driven by a drive motor, which can be used to rotate the adjusting screw 43.

[0033] This configuration allows for adjusting the cutting length of the aluminum rod by rotating the lead screw 43, which in turn rotates the lead screw nut, thereby rotating the sliding frame 44 and the positioning baffle 46. The idler roller 45 effectively supports the outer end of the aluminum rod, preventing it from deforming downwards due to its distance from the material conveying device 3, which would affect the cutting accuracy.

[0034] As needed, the top of the sliding frame 44 is provided with two rollers 45 spaced apart on the side of the positioning baffle 46 corresponding to the sawing device 1.

[0035] Furthermore, to increase the cutting length range of aluminum rods, the linear slide rail 41 can extend to the bottom of the conveying section of the unloading conveying device 3 at one end of the sawing device 1, and the conveying section of the unloading conveying device 3 near the tail end is provided with a detachable structure.

[0036] Example 2, in conjunction with Appendix Figure 1 An automatic aluminum rod sawing machine, based on embodiment one, is provided with a storage device 5 on one side of the material feeding conveyor 3, which is located between the sawing device 1 and the length-fixing device 4, and is perpendicular to it. A transfer device 6 is provided at the connection between the storage device 5 and the material feeding conveyor 3, so as to transfer the cut aluminum rod from the material feeding conveyor 3 to the storage device 5.

[0037] In one possible implementation, combined with the appendix Figure 2 and 4 The storage device 5 includes at least two support beams 51 spaced apart along the conveying direction of the feeding conveyor 3, and the outer end of the support beam 51 is provided with a stop structure 52.

[0038] Preferably, the height of the top surface of the support beam 51 gradually decreases from the inner end to the outer end; that is, under the action of the transfer device 6, the aluminum rod can be transferred from the feeding conveyor 3 to the inner top of the storage device 5, and then under the action of gravity, the aluminum rod rolls to the stop structure 52, waiting to be transferred.

[0039] As needed, to facilitate the movement of aluminum bars on storage device 5 to forklifts, transfer racks, and other operating equipment, the stop structure 52 includes a stop frame 521 with one end rotatably connected to the outer end of support beam 51, and a stop part 522 extending upward at the other end of the stop frame 521; the stop structure 52 also includes a first telescopic device 523 for driving the stop frame 521 to flip; that is, the first telescopic device 523 can drive the stop frame 521 to flip, so that the stop part 522 rises to the top of storage device 5 to stop the aluminum bars and prevent them from falling; or the stop part 522 falls to the bottom of storage device 5, at which time the aluminum bars can roll freely outward to forklifts, transfer racks, and other operating equipment.

[0040] In one possible implementation, combined with the appendix Figure 5 The transfer device 6 includes a transfer frame 61 with one end hinged to the inner end of the storage device 5, and the other end of the transfer frame 61 extends beyond the side of the corresponding unloading conveyor 3 and extends to the top of the conveying part of the unloading conveyor 3.

[0041] The transfer device 6 also includes a second telescopic device 62 for driving the transfer frame 61 to flip, so as to lift the aluminum rod on the unloading conveyor 3 and roll it to the top of the storage device 5 under the guidance of the transfer frame 61.

[0042] Since the position of the transfer frame 61 above the side of the unloading conveyor 3 is at a different height than the position below the top of the conveying part of the unloading conveyor 3, preferably, the two positions are smoothly transitioned.

[0043] The parts of this utility model not described in detail are prior art. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that this utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and are intended to include all changes that fall within the meaning and scope of equivalents within this utility model.
