Description

Technical Field

[0001] This invention relates to the field of aluminum rod production and cutting technology, and in particular to an automatic cutting device for aluminum rod production. Background Technology

[0002] Aluminum bars, as an important industrial raw material, are widely used in building profiles, automotive parts, radiators, aerospace, and other fields. During the processing of aluminum bars, depending on actual usage requirements, it is often necessary to perform end-to-end cutting operations on large batches of long, round aluminum bars.

[0003] Currently, the industry commonly uses bundled cutting to improve production efficiency. This typically involves bundling multiple long, round aluminum rods together (commonly 7 or 10 rods per bundle) and then cutting them in one go using a band saw. This bundled cutting method offers a significant efficiency advantage compared to single-rod cutting, drastically reducing the number of cuts and processing time.

[0004] However, existing technologies often use cable ties for simple binding. Since aluminum rods have a circular cross-section, there are naturally large gaps between adjacent rods, and the cable ties cannot provide sufficient clamping force, resulting in inconsistent and irregularly distributed gaps within the rod bundle. During the band saw's reciprocating cutting motion, the sawing action causes relative vibration and slippage between the aluminum rods, making the cutting process extremely unstable. Secondly, due to the lack of effective restraint between the aluminum rods, uneven end faces and poor perpendicularity are easily generated during cutting, especially in the final stage, where insufficient connecting parts frequently lead to chipping, tearing, and other quality defects, severely affecting the quality of the cut end face. Furthermore, the existing method of binding with cable ties poses significant safety hazards during cutting. If the binding straps loosen or break during vibration, the aluminum rods may scatter, roll, or even fly, posing a threat to the operator's safety.

[0005] Therefore, in order to improve the cutting stability of bundled aluminum bars, improve the end face quality and production safety, this invention provides an automatic cutting device for aluminum bar production. Summary of the Invention

[0006] The purpose of this invention is to solve the problems existing in the prior art and to propose an automatic cutting device for aluminum rod production.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: an automatic cutting device for aluminum rod production, comprising a cutting device body, the cutting device body including a supporting guide seat, a cutting seat mounted on the top wall of the supporting guide seat, a band saw mounted on the cutting seat, and further comprising: a conveying mechanism disposed on the left and right sides of the cutting device body, used to convey bundled aluminum rods from right to left to the cutting station and output them from the cutting station; and two circumferential limiting mechanisms disposed on the cutting seat and symmetrically located on the left and right sides of the band saw, used to circumferentially limit the beginning and end ends of the bundled aluminum rods.

[0008] An end-limiting mechanism, mounted on the cutting seat, is used to provide internal support for the beginning and end ends of the bundled aluminum bars. The end-limiting mechanism includes a flipping support ring and an end-limiting component. The end-limiting component flips on the flipping support ring to switch positions when cutting the beginning and end ends of the bundled aluminum bars. The end-limiting component limits the number of bundled aluminum bars in two working modes.

[0009] The circumferential limiting mechanism works in conjunction with the end limiting mechanism to arrange the bundled aluminum bars to be cut into a tightly arranged structure with a hexagonal cross-section before cutting by using external circumferential constraint and filling the gaps between the aluminum bars.

[0010] In the aforementioned automatic cutting equipment for aluminum rod production, the upper part of the supporting guide seat is trapezoidal, the cutting seat is U-shaped, and a strip groove for band sawing is provided through the middle of the cutting seat.

[0011] In the aforementioned automatic cutting equipment for aluminum rod production, the circumferential limiting mechanism includes a front and rear limiting group and an upper and lower limiting group. The front and rear limiting group includes a front movable limiting member and a rear fixed limiting member that are symmetrically distributed front and rear.

[0012] In the aforementioned automatic cutting equipment for aluminum rod production, the rear fixed limiter is fixedly connected to the inner wall of the cutting seat, and the front movable limiter is slidably connected to the inner wall of the cutting seat. Both the front movable limiter and the rear fixed limiter are equipped with multiple protrusions.

[0013] In the above-mentioned automatic cutting equipment for aluminum rod production, the upper and lower limit groups include standard parts symmetrically distributed on the inner wall of the cutting seat. The standard parts include two protrusions II distributed vertically. The protrusions II are slidably connected to the cutting seat vertically through elastic elements. A wedge is fixed on the protrusions II.

[0014] In the above-mentioned automatic cutting equipment for aluminum rod production, the upper and lower limit groups also include a driving component. The driving component includes a U-shaped driving frame distributed corresponding to the standard part. The U-shaped driving frame is slidably connected to the cutting seat from left to right. A wedge block is fixedly connected to the horizontal end of the U-shaped driving frame.

[0015] In the aforementioned automatic cutting equipment for aluminum rod production, symmetrical flip support rings are installed on the front and rear sides of the cutting seat, and a semi-circular arc-shaped slide rail is provided on the upper part of the flip support ring.

[0016] In the aforementioned automatic cutting equipment for aluminum rod production, the end limiting component includes a bracket mounted on a flipping support ring, and a sleeve corresponding to the end of the bundled aluminum rods is mounted on the bracket.

[0017] In the aforementioned automatic cutting equipment for aluminum rod production, the middle of the sleeve has a main movable seat in the shape of a full moon and an auxiliary movable seat in the shape of a crescent moon that slide left and right.

[0018] In the aforementioned automatic cutting equipment for aluminum rod production, limit rods can be detachably installed on the side of both the main movable seat and the auxiliary movable seat near the end of the bundled aluminum rods.

[0019] Compared with existing technologies, the advantages of this invention are as follows: 1. Through the coordinated operation of the circumferential limiting mechanism and the end limiting mechanism, multiple rigid constraints on the bundled aluminum bars are achieved, which greatly improves the stability of the cutting process, significantly improves the flatness and perpendicularity of the end face, and effectively avoids quality defects such as chipping and tearing caused by vibration. The circumferential limiting mechanism adopts front and rear limiting groups and upper and lower limiting groups. Through the coordinated action of protrusion one and protrusion two, the originally loose and irregularly spaced bundled aluminum bars are organized into a tightly arranged structure with a hexagonal cross-section; at the same time, the end limiting mechanism fills and supports from the inside by inserting the limiting rod into the gap between the aluminum bars.

[0020] 2. The two working modes of the end-limiting component, and the combination of the main and auxiliary movable seats, allow for the cutting of bundles of 7 and 10 aluminum bars respectively. This enables the equipment to quickly switch modes with simple adjustments when handling different batches and quantities of aluminum bars, significantly reducing changeover time and improving equipment utilization and production flexibility. The limit rod is detachable and can be replaced or adjusted as needed. The end-limiting mechanism achieves 180-degree rotation via a flip support ring, allowing for quick position switching between the beginning and end of the cut without manual re-clamping.

[0021] 3. The rigid limiting mechanism eliminates the gaps between aluminum bars, effectively preventing safety accidents caused by aluminum bar displacement, rolling, or even splashing during the cutting process; the inclined top wall design of the supporting guide seat facilitates automatic waste discharge, keeps the working area clean, and further improves the safety and reliability of equipment operation.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Reference Figures 1 to 5 An automatic cutting device for aluminum rod production includes a cutting device body 1, which includes a support guide seat 11. A cutting seat 12 is mounted on the top wall of the support guide seat 11, and a band saw 13 is provided on the cutting seat 12. The automatic cutting device also includes a conveying mechanism 2, two circumferential limiting mechanisms 3, and an end limiting mechanism 4.

[0036] The upper part of the support guide seat 11 is trapezoidal in shape. The inclined top wall of the support guide seat 11 is used to guide the waste generated during the cutting process (such as aluminum chips, shavings, etc.) downwards, which facilitates the automatic sliding and collection of waste, keeps the working area clean, and improves the safety and reliability of equipment operation. The cutting seat 12 is U-shaped, with a strip groove through the middle for the band saw 13 to operate in. The band saw 13 moves up and down in the strip groove to complete the cutting operation of the bundle of aluminum bars 100.

[0037] The conveying mechanism 2 is located on the left and right sides of the cutting equipment body 1. It is used to transport bundled aluminum bars 100 from right to left to the cutting station and to output the finished product from the cutting station after cutting. The conveying mechanism 2 is existing technology and can adopt conventional conveying forms in the field such as roller conveyor, chain conveyor or belt conveyor, which will not be described in detail here.

[0038] Two circumferential limiting mechanisms 3 are disposed on the cutting base 12 and symmetrically located on the left and right sides of the band saw 13, for circumferentially limiting the beginning and end ends (i.e. the two sides of the position to be cut) of the bundled aluminum bars 100. An end limiting mechanism 4 is disposed on the cutting base 12 for internal support of the beginning and end ends of the bundled aluminum bars 100.

[0039] The circumferential limiting mechanism 3 and the end limiting mechanism 4 work together to combine external circumferential constraint and internal gap filling to organize the bundled aluminum bars 100 to be cut into a tightly arranged structure with a hexagonal cross section before cutting. This effectively eliminates the gaps between the aluminum bars, prevents relative sliding and chipping caused by vibration during the cutting process, and further prevents safety accidents caused by aluminum bar displacement, rolling or even splashing during the cutting process.

[0040] Reference Figures 4 to 6 The circumferential limiting mechanism 3 includes a front and rear limiting group 31 and an upper and lower limiting group 32. The front and rear limiting group 31 includes a front movable limiting member 311 and a rear fixed limiting member 312 symmetrically distributed front and rear. Both the front movable limiting member 311 and the rear fixed limiting member 312 are V-shaped. The rear fixed limiting member 312 is fixedly connected to the inner wall of the cutting seat 12, and the front movable limiting member 311 is slidably connected to the inner wall of the cutting seat 12.

[0041] A motor corresponding to the front movable limit member 311 is installed on the front side wall of the cutting seat 12. The output end of the motor is connected to a lead screw (not shown in the figure) that is rotatably installed inside the cutting seat 12. The lead screw is in transmission cooperation with a threaded seat (not shown in the figure) provided at the bottom of the front movable limit member 311, thereby forming a drive mechanism for driving the front movable limit member 311 to slide back and forth.

[0042] On the side where the front movable limiter 311 and the rear fixed limiter 312 are close to each other, there are symmetrically installed protrusions 313. The protrusions 313 are in tangential contact with the outer circular surface of the bundled aluminum rods 100, and are used to limit and regulate the bundled aluminum rods 100 in the front and rear directions of the periphery.

[0043] Reference Figures 4 to 7 The upper and lower limit assembly 32 includes standard components 321 symmetrically distributed on the inner wall of the cutting seat 12. Each standard component 321 includes two symmetrically distributed protrusions, which are slidably connected to the cutting seat 12 via an elastic element (not shown in the figure, preferably a spring). A wedge 322 is fixed to the side of the protrusions closest to the cutting seat 12. The side of the wedge 322 closest to the cutting seat 12 is inclined.

[0044] Reference Figures 4 to 7 The upper and lower limit assembly 32 also includes a driving component, which includes a U-shaped driving frame 323 corresponding to the standard component 321. U-shaped grooves for sliding of the U-shaped driving frame 323 are provided on the left and right side walls of the cutting seat 12. The U-shaped driving frame 323 is driven to slide left and right by an electric slider (not shown in the figure), allowing it to move closer to or further away from the cutting seat 12. The openings of the two corresponding U-shaped driving frames 323 are arranged opposite each other, and a wedge block 324 is fixedly connected to the horizontal end of the U-shaped driving frame 323 near the standard component 321.

[0045] The side of wedge 2 324 closest to wedge 1 322 is inclined to match it. When the U-shaped drive frame 323 moves toward the cutting seat 12, the inclined surfaces of wedge 2 324 and wedge 1 322 cooperate with each other, driving wedge 1 322 to drive protrusion 2 to move inward (i.e., toward the bundled aluminum rods 100) against the elastic force of the elastic element; when the U-shaped drive frame 323 moves away from the cutting seat 12, wedge 2 324 disengages from wedge 1 322, and protrusion 2 moves outward and resets under the reset action of the elastic element.

[0046] Through the above structure, the drive mechanism 1 drives the front movable limiting member 311 to move backward, causing the front movable limiting member 311 and the rear fixed limiting member 312 to move closer to each other. At the same time, the drive member drives the two symmetrically distributed protrusions 2 to move closer to each other, thereby circumferentially organizing the bundled aluminum bars 100 to be cut into a tightly arranged structure with a hexagonal cross-section. In this process, the protrusions 1 313 and 2 work together to force the bundled aluminum bars 100, which originally had gaps, to stick together tightly, and the gaps gradually become regular, creating conditions for subsequent stable cutting.

[0047] Reference Figure 4 and Figure 5The end limiting mechanism 4 includes a flipping support ring 41 and an end limiting component 42. The flipping support ring 41 is symmetrically installed on the front and rear sides of the cutting seat 12, and a semi-circular arc-shaped slide rail is provided on the upper part of the flipping support ring 41.

[0048] Reference Figure 4 , Figure 5 and Figure 8 The end-limiting component 42 includes a bracket 421 mounted on the flipping support ring 41. The bracket 421 is driven by a second drive mechanism to move on a semi-circular slide rail. The second drive mechanism includes a second motor mounted on the front and rear side walls of the cutting seat 12. The output end of the second motor is connected to the bracket 421, driving the bracket 421 to flip along the semi-circular slide rail. Through this flipping structure, the end-limiting component 42 can switch positions when cutting the first and last ends of the bundled aluminum bars 100, that is, after one end is cut, it flips 180 degrees to limit the other end.

[0049] A sleeve 422 corresponding to the end of the bundled aluminum bars 100 is installed on the bracket 421. The middle of the sleeve 422 is driven by an electric slider (not shown in the figure), and is slidably connected to a crescent-shaped main movable seat 423 and a crescent-shaped auxiliary movable seat 424. Limiting rods 425 can be detachably installed on the side of the main movable seat 423 and the auxiliary movable seat 424 near the end of the bundled aluminum bars 100. The limiting rods 425 are tapered near the end of the bundled aluminum bars 100 to facilitate insertion into the gaps between the bundled aluminum bars 100. The coordinated operation of the circumferential limiting mechanism 3 and the end limiting mechanism 4 achieves multiple rigid constraints on the bundled aluminum bars 100.

[0050] It should be noted that the length of the limiting rod 425 is 5-10cm, and the depth of the limiting rod 425 inserted into the gap between the bundled aluminum rods 100 does not exceed the cutting position of the band saw 13, so as to avoid interference with the saw blade.

[0051] To accommodate different numbers of bundled aluminum rods 100, the end-limiting assembly 42 has two operating modes: Mode 1 (see reference) Figure 9 ): This corresponds to cutting 7 aluminum rods into a bundle 100. In this mode, the limiting rods 425 (preferably 6 rods) on the main movable seat 423 are inserted into the gap between the middle ring of aluminum rods, and the auxiliary movable seat 424 is in a retracted state and does not participate in the work.

[0052] Mode 2 (Reference) Figure 10 ): Corresponding to the cutting of 10 aluminum rods 100 bundled together. In this mode, the 6 limiting rods 425 on the main movable seat 423 and the limiting rods 425 (preferably 4) on the auxiliary movable seat 424 are inserted into the gap between the middle ring of aluminum rods to form an internal support for the arrangement of the 10 aluminum rods.

[0053] This modular and adjustable structural design allows the equipment to quickly switch modes with simple adjustments when dealing with different batches and numbers of aluminum bars, greatly reducing changeover time and improving equipment utilization and production flexibility.

[0054] The specific operating steps of the automatic cutting equipment for aluminum rod production are as follows: First, according to the number of aluminum rods to be cut (7 or 10), adjust the end limit component 42 to the corresponding working mode, and select the appropriate number and position of the main movable seat 423, auxiliary movable seat 424 and limit rod 425.

[0055] Secondly, the bundled aluminum rods 100 are conveyed from right to left to the cutting station by the conveying mechanism 2, so that their heads reach the cutting position of the band saw 13.

[0056] Then, the circumferential limiting mechanism 3 is activated: the drive mechanism one drives the front movable limiting member 311 to move backward, cooperating with the rear fixed limiting member 312 to limit the movement in the front-back direction; the drive member drives the U-shaped drive frame 323 to move towards the cutting seat 12, and through the cooperation of the second wedge 324 and the first wedge 322, drives the symmetrically distributed protrusions two to move inward, limiting the movement in the vertical direction. At this point, the bundled aluminum bars 100 are arranged in a tight hexagonal pattern in the circumferential direction.

[0057] Next, the end limiting mechanism 4 is activated: the drive mechanism 2 drives the bracket 421 to rotate along the semi-circular slide rail to the working position, so that the sleeve 422 is aligned with the end of the bundled aluminum rods 100; then the main movable seat 423 (and the auxiliary movable seat 424) is driven to slide towards the bundled aluminum rods 100, so that the limiting rod 425 is inserted into the gap between the aluminum rods to achieve end internal support.

[0058] After the above-mentioned limiting is completed, the band saw 13 starts to longitudinally cut the bundle of aluminum bars 100. During the cutting process, since the bundle of aluminum bars 100 has been limited in multiple directions and at the ends, the aluminum bars are relatively fixed. Even if the saw blade moves up and down during the cutting process of the band saw 13, there will be no vibration or relative slippage between the aluminum bars, which greatly improves the stability of the cutting process, significantly improves the flatness and perpendicularity of the end face, and effectively avoids quality defects such as chipping and tearing caused by vibration.

[0059] After one end is cut, the band saw 13 resets. The limiting rod 425 of the end limiting mechanism 4 retracts, and the flipping support ring 41 flips the end limiting component 42 180 degrees to the other end, enabling quick switching of positions when cutting the first and last ends without manual re-clamping. The above limiting steps are repeated to cut the other end of the bundled aluminum bars 100.

[0060] After all cutting is completed, all limit mechanisms are reset, and the conveying mechanism 2 outputs the finished aluminum rods and simultaneously sends the next batch of aluminum rods to be cut into the work station to enter the next work cycle.
