Description

Technical Field

[0001] This invention relates to the field of aluminum bar processing technology, specifically to a fixed-width clamping and cutting device for aluminum bar forming. Background Technology

[0002] In the forming and cutting of aluminum bars, existing conventional cutting devices mostly adopt a single-sided cutting blade feed or a step-by-step drive structure for the upper and lower cutting blades. Before cutting, the aluminum bar is simply clamped and positioned by a vertical clamping block. This type of structure has the following shortcomings: First, vertical clamping alone cannot limit the lateral deformation of the material around the cut during the cutting process. When the aluminum bar is subjected to shearing force, it is prone to arching and slippage, resulting in a tilted cut surface, a large amount of burrs, and difficulty in ensuring the cutting dimensional accuracy and cross-sectional quality. Second, clamping and positioning and cutting actions usually require independent drive sources for separate control, resulting in a complex equipment structure, difficulty in coordinating the action sequence, and low cutting efficiency. Third, the upper and lower cutting blades have poor synchronization, which easily leads to uneven cutting force, further aggravating the deformation of the aluminum bar and the wear of the cutting blades. To address these issues, this invention develops a fixed-width clamping and cutting device for aluminum bar forming. Summary of the Invention

[0003] The purpose of this invention is to provide a fixed-width clamping and cutting device for aluminum bar forming, so as to solve the problems of poor positioning and clamping effect, easy deformation of aluminum bar during cutting, low cut quality, and dispersed clamping and cutting action drive, complex structure and low efficiency of existing aluminum bar cutting equipment.

[0004] To achieve the above objectives, the technical solution provided by the present invention is as follows: A fixed-width clamping and cutting device for aluminum foil forming includes a worktable and a cutting component. A cutting groove is formed through the surface of the worktable, and the cutting component is straddling the worktable and corresponding to the cutting groove. The cutting assembly includes mounting seats on both sides of the worktable. Each mounting seat contains a double-ended lead screw that is vertically rotatably mounted. The double-ended lead screw has upper and lower threaded sections with opposite directions of rotation. The upper threaded sections of both double-ended lead screws are threaded with first sliders, and the lower threaded sections of both double-ended lead screws are threaded with second sliders. An upper cutter is installed between the two first sliders, and a lower cutter is installed between the two second sliders. The upper and lower cutters are vertically opposite each other and have matching cutting edges. Two sets of upper clamping assemblies are located between the two first sliders and on either side of the upper cutter. Two sets of lower clamping assemblies are located between the two second sliders and on either side of the lower cutter. The upper and lower clamping assemblies correspond one-to-one. The two mounting bases have a first limiting groove that slides with the upper clamping component and a second limiting groove that slides with the lower clamping component on their opposite sidewalls. The first and second limiting grooves are configured such that when the double-ended lead screw drives the first and second sliders to move toward each other, the upper and lower clamping components are first guided to vertically feed and clamp the aluminum bar, and then the upper and lower clamping components are guided to horizontally move outward a preset distance in the direction away from the cutting groove to tension both sides of the aluminum bar to be cut. Subsequently, the upper and lower cutters continue to feed toward each other to complete the cutting.

[0005] Preferably, both the first limiting groove and the second limiting groove are composed of a vertical limiting groove, a transition limiting groove and a horizontal limiting groove connected in sequence. The vertical limiting groove extends vertically to guide the clamping assembly to clamp vertically. The horizontal limiting groove extends horizontally in a direction away from the cutting groove to guide the clamping assembly to tension horizontally. The two horizontal limiting grooves on the same mounting base are arranged in a direction away from each other. The transition limiting groove is an arc-shaped groove that smoothly connects the vertical limiting groove and the horizontal limiting groove.

[0006] Preferably, the upper clamping assembly includes a hinge seat, a connecting rod, a mounting shaft, and a clamping member. The hinge seat is fixed to the side wall of the first slider. One end of the connecting rod is hinged to the hinge seat, and the other end is rotatably connected to the mounting shaft. The clamping member is horizontally mounted between the two mounting shafts. The mounting shaft is slidably embedded in the first limiting groove on the corresponding side. The lower clamping assembly and the upper clamping assembly have symmetrical and identical structures.

[0007] Preferably, the clamping component includes a fixing strip and a clamping strip. The two ends of the fixing strip are respectively fixed to the mounting shaft on the corresponding side. At least two sets of adjusting bolts are vertically threaded through and threaded onto the fixing strip. The lower end of the adjusting bolts is connected to the clamping strip and is used to adjust the vertical extension of the clamping strip to adapt to aluminum bars of different thicknesses.

[0008] Preferably, an elastic rubber pad is fixed to the bottom surface of the pressing strip, and the lower surface of the elastic rubber pad is provided with anti-slip stripes to increase the contact friction with the surface of the aluminum bar.

[0009] Preferably, the workbench surface is provided with an aluminum positioning component. The positioning component includes two sets of horizontal positioning strips disposed on both sides of the cutting groove and a vertical positioning strip disposed at the material discharge end of the workbench. Several rollers are provided on the facing sides of the two sets of horizontal positioning strips. The vertical positioning strip and the two sets of horizontal positioning strips are slidably connected to the workbench and are used to adjust the distance between the vertical positioning strip and the cutting groove and the distance between the two sets of horizontal positioning strips, respectively.

[0010] Preferably, both of the mounting base cavities are provided with a cleaning mechanism, which includes an upper elastic airbag and a lower elastic airbag respectively installed at the top and bottom of the mounting base cavity. The bottom movable end of the upper elastic airbag is fixedly connected to the first slider, and the top movable end of the lower elastic airbag is fixedly connected to the second slider. The upper elastic airbag is connected to the upper air inlet pipe and the upper air outlet pipe through two one-way valves respectively. The upper air blowing assembly is installed on the side wall of the blade holder of the upper cutter, and the air blowing port of the upper air blowing assembly is aligned with the cutting edge area of ​​the upper cutter. The lower elastic airbag is connected to the lower air inlet pipe and the lower air outlet pipe via two one-way valves respectively. The lower cutter's blade holder sidewall is equipped with a lower air blowing assembly, and the air blowing port of the lower air blowing assembly is aligned with the cutting edge area of ​​the lower cutter.

[0011] Preferably, both the upper and lower air outlet pipes are retractable flexible hoses.

[0012] Preferably, both the upper air blowing assembly and the lower air blowing assembly include two sets of strip-shaped air blowing nozzles, which are respectively disposed on both sides of the corresponding cutter, with the air blowing end obliquely aligned with the cutting edge area of ​​the cutter.

[0013] Preferably, the cleaning mechanism further includes two sets of follow-up air nozzles, which are respectively located on the opposite sides of the two sets of upper pressing components and are obliquely aligned with the periphery of the cut on the upper surface of the aluminum bar. The follow-up air nozzles are connected to the upper air outlet pipe.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention uses a double-headed lead screw to synchronously drive the upper and lower sliders to move in opposite directions, thereby driving the upper and lower cutters to complete the cutting action synchronously. The cutting force is symmetrical and uniform. At the same time, the clamping component and the cutter are linked with the sliders, and the trajectory constraint of the limiting groove realizes the continuous sequential action of vertical clamping, horizontal tensioning and synchronous cutting. This ensures that the aluminum bar in the cutting area is kept in a constant tension state during the cutting process, effectively counteracting the tendency of material shrinkage, arching and slippage caused by the cutting shearing force, avoiding the collapse, slant cutting and burr deformation of the cut surface, ensuring the stable and consistent cutting width dimension, and significantly improving the flatness of the cut surface and processing accuracy.

[0018] 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.

[0019] like Figure 1-8 As shown: The embodiments of the present invention are as follows: A fixed-width clamping and cutting device for aluminum foil forming includes a worktable 1 and a cutting component. A cutting groove 2 is formed through the surface of the worktable 1. The cutting component is straddling the worktable 1 and is arranged corresponding to the cutting groove 2. The cutting assembly includes mounting bases 3 located on both sides of the workbench 1. Each mounting base 3 has a double-ended lead screw 4 vertically rotatably mounted inside it. The double-ended lead screw 4 has upper and lower threaded sections with opposite directions of rotation. The upper threaded sections of the two double-ended lead screws 4 are threadedly fitted with first sliders 5, and the lower threaded sections of the two double-ended lead screws 4 are threadedly fitted with second sliders 6. An upper cutter 7 is installed between the two first sliders 5, and a lower cutter 8 is installed between the two second sliders 6. The upper cutter 7 and the lower cutter 8 are vertically opposite each other and have matching cutting edges. There are two sets of upper clamping components 9 located on both sides of the upper cutter 7 between the two first sliders 5, and two sets of lower clamping components 10 located on both sides of the lower cutter 8 between the two second sliders 6. The upper clamping components 9 and the lower clamping components 10 correspond one-to-one. The two mounting bases 3 have a first limiting groove 11 that slides with the upper pressing component 9 and a second limiting groove 12 that slides with the lower pressing component 10 on their opposite sidewalls. The first limiting groove 11 and the second limiting groove 12 are configured such that when the double-ended lead screw 4 drives the first slider 5 and the second slider 6 to move towards each other, the upper pressing component 9 and the lower pressing component 10 are first guided to vertically feed and press the aluminum bar, and then the upper pressing component 9 and the lower pressing component 10 are guided to horizontally move outward a preset distance in the direction away from the cutting groove 2 to tension the two sides of the aluminum bar to be cut. Then the upper cutter 7 and the lower cutter 8 continue to feed towards each other to complete the cutting.

[0020] Specifically, both the first limiting groove 11 and the second limiting groove 12 are composed of a vertical limiting groove, a transition limiting groove and a horizontal limiting groove connected in sequence. The vertical limiting groove extends vertically and is used to guide the clamping assembly to clamp vertically. The horizontal limiting groove extends horizontally in a direction away from the cutting groove 2 and is used to guide the clamping assembly to tension horizontally. The two horizontal limiting grooves on the same mounting base 3 are arranged in a direction away from each other. The transition limiting groove is an arc-shaped groove that smoothly connects the vertical limiting groove and the horizontal limiting groove.

[0021] As can be seen from the above description, setting the limiting groove as a three-section connecting structure of vertical limiting groove, arc-shaped transition limiting groove and horizontal limiting groove can guide the clamping component to smoothly complete the vertical to horizontal movement reversal, avoid jamming and impact during the reversal process, and ensure smooth and reliable clamping action. At the same time, the horizontal limiting grooves on both sides of the same mounting base are arranged in opposite directions, which can make the clamping components on both sides tension outward synchronously, and the aluminum bar is subjected to symmetrical and uniform force on both sides, resulting in stable tensioning and positioning effect.

[0022] Specifically, the upper clamping assembly 9 includes a hinge seat 91, a connecting rod 92, a mounting shaft 93, and a clamping member 94. The hinge seat 91 is fixed to the side wall of the first slider 5. One end of the connecting rod 92 is hinged to the hinge seat 91, and the other end is rotatably connected to the mounting shaft 93. The clamping member 94 is horizontally mounted between the two mounting shafts 93. The mounting shafts 93 are slidably embedded in the first limiting groove 11 on the corresponding side. The lower clamping assembly 10 and the upper clamping assembly 9 have symmetrical and identical structures.

[0023] As can be seen from the above description, the clamping assembly adopts a linkage structure consisting of a hinged seat, a connecting rod, and a mounting shaft. With the guidance constraint of the limiting groove, it can adaptively generate horizontal displacement while the slider is vertically fed. The transmission is reliable, the parts are simple in structure, the processing and assembly are easy, and it is convenient for later maintenance and replacement.

[0024] Specifically, the clamping component 94 includes a fixing strip 941 and a clamping strip 942. The two ends of the fixing strip 941 are respectively fixed to the mounting shaft 93 on the corresponding side. At least two sets of adjusting bolts 943 are vertically threaded through and threaded onto the fixing strip 941. The lower end of the adjusting bolt 943 is connected to the clamping strip 942 to adjust the vertical extension of the clamping strip 942 and adapt to aluminum bars of different thicknesses.

[0025] As can be seen from the above description, the clamping component connects the fixing strip and the clamping strip through adjusting bolts, which can flexibly adjust the vertical extension of the clamping strip to adapt to aluminum workpieces of different thicknesses and ensure that a stable clamping force can be obtained under different thicknesses.

[0026] Specifically, an elastic rubber pad is fixed to the bottom surface of the clamping strip 942, and anti-slip stripes are provided on the lower surface of the elastic rubber pad to increase the contact friction with the aluminum bar surface.

[0027] As can be seen from the above description, setting an elastic rubber pad with anti-slip stripes on the bottom surface of the clamping strip can not only increase the contact friction with the surface of the aluminum bar and prevent slippage and loosening during horizontal tensioning, but also prevent damage to the surface of the aluminum bar during clamping through elastic buffering, thus protecting the appearance quality of the workpiece.

[0028] Specifically, the workbench 1 is equipped with an aluminum positioning component, which includes two sets of horizontal positioning strips 14 located on both sides of the cutting groove 2 and a vertical positioning strip 15 located at the discharge end of the workbench 1. Several rollers 141 are provided on the facing sides of the two sets of horizontal positioning strips 14. The vertical positioning strip 15 and the two sets of horizontal positioning strips 14 are slidably connected to the workbench 1 and are used to adjust the distance between the vertical positioning strip 15 and the cutting groove 2 and the distance between the two sets of horizontal positioning strips 14, respectively.

[0029] As can be seen from the above description: the adjustable horizontal and vertical positioning bars on the worktable can be used to fix the width and cutting length of the aluminum bar respectively, ensuring the consistency of the cutting dimensions; the rollers on the horizontal positioning bars can greatly reduce the frictional resistance when feeding the aluminum bar, making feeding smooth and labor-saving; the positioning bars can be slidably adjusted to adapt to the processing needs of aluminum bars with different widths and cutting lengths.

[0030] Specifically, both mounting bases 3 are equipped with cleaning mechanisms 16. The cleaning mechanisms include an upper elastic airbag 161 and a lower elastic airbag 162 installed at the top and bottom of the mounting base 3 respectively. The bottom movable end of the upper elastic airbag 161 is fixedly connected to the first slider 5, and the top movable end of the lower elastic airbag 162 is fixedly connected to the second slider 6. The upper elastic airbag 161 is connected to the upper air inlet pipe 163 and the upper air outlet pipe 164 respectively through two one-way valves. The upper air blowing assembly 165 is installed on the side wall of the blade holder of the upper cutter 7, and the air blowing port of the upper air blowing assembly 165 is aligned with the cutting edge area of ​​the upper cutter 7. The lower elastic airbag 162 is connected to the lower air inlet pipe 166 and the lower air outlet pipe 167 via two one-way valves respectively. The lower cutter 8 has a lower air blowing assembly 168 installed on the side wall of the blade holder. The air blowing port of the lower air blowing assembly 168 is aligned with the cutting edge area of ​​the lower cutter 8.

[0031] As can be seen from the above description, the cleaning mechanism is composed of upper and lower elastic airbags. The airbags are driven to expand and contract by the reciprocating motion of the slider to generate airflow, which automatically blows air to clean the cutting edge and removes chips. No additional air source and driving device are required. The structure is compact and energy-saving. It can remove aluminum chips that adhere to the cutting edge during the cutting process in a timely manner, and avoid the accumulation of aluminum chips from affecting the cutting accuracy and the service life of the tool.

[0032] Specifically, both the upper vent pipe 164 and the lower vent pipe 167 are retractable hoses.

[0033] As can be seen from the above description, the upper and lower air outlet pipes are designed as retractable flexible hoses that can extend and retract synchronously with the cutter and slider, avoiding pulling, bending and interference of the pipes during the movement, ensuring stable airflow and smooth air delivery.

[0034] Specifically, both the upper air blowing assembly 165 and the lower air blowing assembly 168 include two sets of strip-shaped air blowing nozzles, which are respectively located on both sides of the corresponding cutter, with the air blowing end obliquely aligned with the cutting edge area of ​​the cutter.

[0035] As can be seen from the above description, the air blowing assembly uses two sets of strip-shaped air nozzles placed on both sides of the cutter and angled towards the cutting edge area. The airflow covers the entire area without any dead corners, which can effectively improve the cleaning effect of aluminum chips on the cutting edge.

[0036] Specifically, the cleaning mechanism 16 also includes two sets of follow-up air nozzles 169. The two sets of follow-up air nozzles 169 are respectively located on the opposite sides of the two sets of upper pressing components 9, and are obliquely aligned with the periphery of the cut on the upper surface of the aluminum bar. The follow-up air nozzles 169 are connected to the upper air outlet pipe 164.

[0037] As can be seen from the above description, the follow-up air nozzle moves synchronously with the upper clamping component. During the cutting and return process, it can continuously blow air around the aluminum bar cut to promptly blow away the debris generated during cutting, thus preventing aluminum chips from remaining on the aluminum bar surface and affecting subsequent processing and surface quality.

[0038] like Figure 1-8 As shown, Embodiment 1 of the present invention is as follows: This embodiment discloses a fixed-width clamping and cutting device for aluminum bar forming, which mainly includes a workbench 1 and a cutting component. The workbench 1 is a horizontally arranged rectangular platform with a cutting groove 2 extending horizontally through the middle of its platform. The cutting component is mounted above the workbench 1, and the cutting station corresponds vertically to the cutting groove 2.

[0039] The cutting assembly includes two mounting bases 3, which are vertically fixed to the left and right sides of the workbench 1, respectively. Each mounting base 3 has a vertical mounting cavity inside, and a double-ended lead screw 4 is vertically rotatably mounted inside the mounting cavity. The double-ended lead screw 4 is divided into an upper threaded section and a lower threaded section, with the two threads rotating in opposite directions. The upper threaded section of both double-ended lead screws 4 is threadedly fitted with a first slider 5, and the lower threaded section is threadedly fitted with a second slider 6. The sliders slide against the inner wall of the mounting cavity and can slide vertically along the mounting cavity. The two double-ended lead screws 4 can be connected to a drive motor through a synchronous transmission mechanism to achieve synchronous rotation in the same direction, thereby driving the first sliders 5 on both sides to rise and fall synchronously, and the second sliders 6 on both sides to rise and fall synchronously.

[0040] An upper cutter 7 is horizontally fixed between two first sliders 5, and a lower cutter 8 is horizontally fixed between two second sliders 6. The upper cutter 7 and the lower cutter 8 are arranged vertically opposite each other, and their cutting edges are matched to form a cutting structure. Two sets of upper clamping components 9 are also provided between the two first sliders 5, located on the front and rear sides of the upper cutter 7, respectively. Two sets of lower clamping components 10 are provided between the two second sliders 6, located on the front and rear sides of the lower cutter 8, respectively. The upper clamping components 9 and the lower clamping components 10 correspond one-to-one, working together to clamp the front and rear sides of the area to be cut on the aluminum bar.

[0041] On the inner sidewalls of the two mounting bases 3 facing each other, two sets of first limiting grooves 11 and two sets of second limiting grooves 12 are respectively provided. The first limiting grooves 11 are slidably engaged with the upper pressing component 9, and the second limiting grooves 12 are slidably engaged with the lower pressing component 10. The trajectories of the first limiting grooves 11 and the second limiting grooves 12 are configured as follows: when the double-ended lead screw 4 drives the first slider 5 to move downward and the second slider 6 to move upward, the upper pressing component 9 and the lower pressing component 10 first feed vertically towards each other along the limiting grooves to press the aluminum bar up and down; as the sliders continue to move towards each other, the pressing components change direction along the limiting grooves and move horizontally outward a preset distance away from the cutting groove 2 to tension the front and rear sides of the area to be cut of the aluminum bar outward; then the upper and lower cutters continue to feed towards each other until the cutting edges engage to complete the cutting.

[0042] In this embodiment, the first limiting groove 11 and the second limiting groove 12 have the same structure, both consisting of three interconnected segments: a vertical limiting groove, a transition limiting groove, and a horizontal limiting groove. The vertical limiting groove extends vertically, corresponding to the vertical feed during the pressing stage; the horizontal limiting groove extends horizontally away from the cutting groove 2, corresponding to the horizontal outward movement during the tensioning stage; the two horizontal limiting grooves on the same mounting base 3 are arranged in mutually distancing directions, i.e., the front horizontal limiting groove extends forward and the rear horizontal limiting groove extends backward. The transition limiting groove is an arc-shaped segment that smoothly connects the lower end of the vertical limiting groove and the inner end of the horizontal limiting groove, ensuring smooth and impact-free movement of the pressing assembly during reversal.

[0043] The upper clamping assembly 9 includes a hinge seat 91, a connecting rod 92, a mounting shaft 93, and a clamping member 94. The hinge seat 91 is fixedly connected to the inner wall of the first slider 5. The upper end of the connecting rod 92 is hinged to the hinge seat 91, and the lower end is rotatably connected to the mounting shaft 93. Two mounting shafts 93 extend laterally, and the clamping member 94 is horizontally mounted between them. The outer ends of the mounting shafts 93 are slidably embedded in the first limiting groove 11 on the corresponding side. The lower clamping assembly 10 has a completely symmetrical structure with the upper clamping assembly 9. The outer end of its mounting shaft is slidably embedded in the second limiting groove 12 on the corresponding side. When the slider moves vertically, the mounting shaft slides along the limiting groove, causing the connecting rod to swing around the hinge seat, so that the clamping member simultaneously produces vertical and horizontal displacement.

[0044] In this embodiment, the clamping member 94 includes a fixing strip 941 and a clamping strip 942. Both ends of the fixing strip 941 are fixedly connected to the mounting shaft 93 on the corresponding side. At least two sets of adjusting bolts 943 are vertically threaded through the fixing strip 941. The adjusting bolts 943 are threaded into the fixing strip 941, and their lower ends are rotatably connected to the clamping strip 942. By turning the adjusting bolts 943, the vertical extension of the clamping strip 942 relative to the fixing strip 941 can be adjusted, thereby adapting to aluminum workpieces of different thicknesses. An elastic rubber pad is fixedly provided on the bottom surface of the clamping strip 942. The lower surface of the elastic rubber pad is machined with anti-slip stripes, which can increase the friction with the surface of the aluminum workpiece, prevent slippage during tensioning, and avoid rigidly damaging the workpiece surface.

[0045] In this embodiment, an aluminum bar positioning component is provided on the workbench 1. The positioning component includes two sets of horizontal positioning strips 14 and one set of vertical positioning strips 15. The two sets of horizontal positioning strips 14 are respectively located on the front and rear sides of the cutting groove 2, extending along the feeding direction, and are used to limit the width position of the aluminum bar. Several rollers 141 are installed along the length direction on the facing sides of the two sets of horizontal positioning strips 14. The axis of the rollers 141 is set vertically, which can reduce the frictional resistance when feeding the aluminum bar. The vertical positioning strip 15 is located at the discharge end of the workbench 1, extending horizontally, and is used to limit the cutting length of the aluminum bar. The vertical positioning strip 15 and the two sets of horizontal positioning strips 14 are all slidably connected to the workbench 1 and can be fixed in position by locking components. They are used to adjust the distance between the vertical positioning strip 15 and the cutting groove 2, and the distance between the two sets of horizontal positioning strips 14, respectively, to adapt to aluminum bars of different specifications.

[0046] In this embodiment, a cleaning mechanism 16 is provided in the inner cavity of each of the two mounting bases 3. The cleaning mechanism 16 includes an upper elastic airbag 161 and a lower elastic airbag 162. The upper elastic airbag 161 is installed at the top of the inner cavity of the mounting base 3, and its movable end at the bottom is fixedly connected to the top surface of the first slider 5. The lower elastic airbag 162 is installed at the bottom of the inner cavity of the mounting base 3, and its movable end at the top is fixedly connected to the bottom surface of the second slider 6. When the slider moves up and down, it can drive the corresponding airbag to compress or expand.

[0047] Two one-way valves are connected to the upper elastic airbag 161, which are respectively connected to the upper air inlet pipe 163 and the upper air outlet pipe 164. The upper air inlet pipe 163 is connected to the outside atmosphere, and the upper air outlet pipe 164 extends to the upper cutter 7. An upper air blowing assembly 165 is installed on the side wall of the cutter holder of the upper cutter 7. The upper air blowing assembly 165 is connected to the upper air outlet pipe 164, and its air blowing port is aligned with the cutting edge area of ​​the upper cutter 7. Similarly, two one-way valves are connected to the lower elastic airbag 162, which are respectively connected to the lower air inlet pipe 166 and the lower air outlet pipe 167. A lower air blowing assembly 168 is installed on the side wall of the cutter holder of the lower cutter 8, and its air blowing port is aligned with the cutting edge area of ​​the lower cutter 8. When the airbag expands, outside air enters the airbag unidirectionally through the air inlet pipe; when the airbag is compressed, internal air is sent unidirectionally to the air blowing assembly through the air outlet pipe to blow air and remove chips from the cutting edge.

[0048] In this embodiment, both the upper air outlet pipe 164 and the lower air outlet pipe 167 are retractable corrugated hoses, which can extend and retract synchronously with the cutter to avoid pipe interference. Both the upper air blowing assembly 165 and the lower air blowing assembly 168 include two sets of strip-shaped air nozzles, which are respectively installed on the front and rear sides of the corresponding cutter, with the air blowing end obliquely aligned with the cutting edge area of ​​the cutter to achieve full circumferential chip removal.

[0049] In this embodiment, the cleaning mechanism 16 also includes two sets of follow-up air nozzles 169. The two sets of follow-up air nozzles 169 are respectively installed on the opposing sides of the two sets of upper pressing components 9, with the air blowing end pointing obliquely downwards and aimed at the periphery of the cut on the upper surface of the aluminum bar. The follow-up air nozzles 169 are connected to the upper air outlet pipe 164 through the branch pipe and can move synchronously with the upper pressing components to blow air around the cut to remove debris during cutting.

[0050] The specific working process of the above embodiments is as follows: The aluminum bar to be cut is pushed onto the worktable 1 along the feeding direction. The aluminum bar enters between two sets of transverse positioning strips 14. The rollers 141 on the inner side of the transverse positioning strips 14 roll in contact with the side wall of the aluminum bar, which not only restricts the width direction deviation of the aluminum bar, but also greatly reduces the feeding friction resistance. The aluminum bar is continuously pushed until its end abuts against the vertical positioning strip 15, completing the positioning of the cutting length. The distance between the vertical positioning strip 15 and the cutting groove 2, as well as the distance between the two sets of transverse positioning strips 14, can be pre-adjusted according to processing requirements to accommodate aluminum bar workpieces of different widths and cutting lengths.

[0051] Then, the drive device is started, and the two double-ended lead screws 4 are driven to rotate synchronously in the same direction through the synchronous transmission mechanism. Since the upper and lower thread sections of the double-ended lead screws 4 rotate in opposite directions, the first sliders 5 on both sides move downward synchronously, and the second sliders 6 on both sides move upward synchronously. During this stage, the mounting shaft 93 of the upper clamping assembly 9 slides vertically along the vertical limiting groove of the first limiting groove 11, and the mounting shaft of the lower clamping assembly slides vertically along the vertical limiting groove of the second limiting groove 12. The connecting rod 92 maintains a vertical posture and only drives the clamping part 94 to make vertical feed. Until the clamping strips 942 of the upper and lower clamping assemblies press against both sides of the aluminum bar to be cut area from the upper and lower sides, the vertical clamping and positioning is completed. The elastic rubber pad is deformed by pressure, which increases the contact friction and avoids rigid pressure damage to the surface of the aluminum bar.

[0052] Then the double-ended lead screw 4 continues to rotate, and the first slider 5 and the second slider 6 keep feeding towards each other; at this time, the mounting shaft 93 enters the arc-shaped transition limit groove of the limit groove, and gradually changes direction along the arc trajectory, driving the connecting rod 92 to swing around the hinge seat 91 in the direction away from the cutting groove 2, so that the clamping member 94 maintains the vertical clamping force while simultaneously shifting horizontally to the outside; when the mounting shaft 93 slides into the horizontal limit groove, the clamping member 94 completes the horizontal outward movement of the preset distance, and through the static friction between the clamping surface and the aluminum bar, the front and rear sides of the area to be cut of the aluminum bar are simultaneously pulled outward and tightened, so that the aluminum bar material in the cutting area is in a taut state, thereby fundamentally offsetting the tendency of material shrinkage and arching caused by the cutting shearing force.

[0053] After the tensioning action is completed, the first slider 5 and the second slider 6 continue to move towards each other, and the mounting shaft 93 remains in the horizontal limiting groove. The clamping assembly continues to maintain the tensioned state. The upper cutter 7 moves down with the first slider 5 and the lower cutter 8 moves up with the second slider 6. The blades of the two cutters contact the aluminum bar synchronously and complete the opposite shearing. The cutting force is symmetrical and uniform in the vertical direction, ensuring that the cut surface is flat.

[0054] At the same time, the first slider 5 moves downward and the second slider 6 moves upward, causing the upper elastic airbag 161 and the lower elastic airbag 162 to expand respectively. Outside air is drawn into the airbag through the one-way valve of the air inlet pipe, completing the gas reserve for cleaning. After cutting, the drive device drives the double-headed lead screw 4 to rotate in the opposite direction. The first slider 5 moves upward and the second slider 6 moves downward, moving in opposite directions. The upper and lower cutters first disengage from the aluminum bar cut, and then the mounting shaft 93 moves from the horizontal limiting groove through the transition limiting groove back to the vertical limiting groove. The clamping assembly first resets horizontally inward to release the tension, and then rises / falls vertically to release the clamping on the aluminum bar. The first slider 5 moves downward to compress the upper elastic air bag 161, and the second slider 6 moves upward to compress the lower elastic air bag 162. The air pressure inside the air bag increases, and the gas flows out from the air outlet pipe through the one-way valve and is sent to the upper air blowing assembly 165, the lower air blowing assembly 168 and the follower air blowing nozzle 169 respectively. The two sets of strip-shaped air blowing nozzles blow obliquely from both sides of the cutter edge. The follower air blowing nozzle 169 is positioned synchronously with the upper clamping assembly and blows obliquely around the cut edge on the upper surface of the aluminum bar, simultaneously removing the aluminum chips generated during cutting, and preventing the chips from adhering to the cutting edge or remaining on the workpiece surface.

[0055] Once the clamping components have fully reset, the cut aluminum bar can be removed, or the material to be processed can be pushed on to enter the next cutting cycle.
