Description

Technical Field

[0001] The present invention relates to the technical field of sawing equipment, and particularly relates to a profile sawing device. Background Art

[0002] The use of profiles is relatively common in building structures. Profiles are objects with a certain geometric shape made of materials with a certain strength and toughness through processes such as rolling, extrusion, and casting. During the processing of profiles, sawing treatment is required for the profiles.

[0003] Chinese Patent with the authorization announcement number CN109226882B discloses an automatic aluminum profile sawing device, which includes a feeding frame, a feeding mechanism that can be lifted and lowered in front of the feeding frame, a material taking mechanism at the rear of the feeding frame, and a sawing device on the right side of the feeding frame; on the material taking mechanism, there is a material taking mechanism located above the feeding mechanism and a displacement mechanism for changing the position of the material taking mechanism; on the feeding frame, there are a feeding ejector rod located on the upper layer and a feeding roller assembly evenly arranged on the lower layer; in actual use, the straight aluminum profiles to be processed can be stacked and placed on the feeding mechanism, and then the material taking mechanism grabs one or more straight aluminum profiles from the stack of straight aluminum profiles and places them on the feeding roller assembly, and the single or multiple straight aluminum profiles are pushed to the sawing device by the feeding ejector rod for sawing; this method avoids manual placement of straight aluminum profiles, improves production and processing efficiency, reduces production costs, and improves the automation during the sawing of straight aluminum profiles.

[0004] When the existing sawing device is working, after the sawing blade finishes cutting a single profile, it will continue to move to cut the remaining multiple profiles until all the profiles are cut. When the profile is just cut, its end face will expand and deform due to heat. When the sawing blade moves forward or returns, the cutting surfaces on both sides of the sawing blade will rub against the cut surface of the profile, resulting in an increase in the surface roughness of the profile end face, and defects such as scratches and burrs, which affect the quality of the finished product. Summary of the Invention

[0005] The present invention provides a profile sawing device, aiming to solve the technical problem that in the related art, when the existing sawing device is working, after the sawing blade finishes cutting a single profile, it will continue to move to cut the remaining multiple profiles until all the profiles are cut. When the profile is just cut, its end face will expand and deform due to heat. When the sawing blade moves forward or returns, the cutting surfaces on both sides of the sawing blade will rub against the cut surface of the profile, resulting in an increase in the surface roughness of the profile end face, and defects such as scratches and burrs, which affect the quality of the finished product.

[0006] A profile sawing device of the present invention comprises: a workbench, a sawing knife, a clamping cylinder and a clamping plate; a vertical clamping module is also arranged on the workbench, and the vertical clamping module comprises a clamping unit and a pushing unit; the clamping unit comprises a telescopic member arranged on the workbench, a mounting plate arranged on the telescopic member, a plurality of bearing plates arranged on the mounting plate with horizontal intervals front and back, two mounting tables arranged on the bearing plate on the left and right, a moving table connected to the mounting table by spring sliding, a clamping member fixed on the moving table, and a force storage component is arranged on the moving table, the force storage component comprises a force storage component arranged on the moving table, and a push rod sliding horizontally on the moving table; the pushing unit comprises a sliding plate sliding horizontally on the mounting plate front and back and located between the left and right mounting tables, and a plurality of extrusion blocks arranged on both sides of the sliding plate, the extrusion blocks respectively corresponding to the push rods, and the extrusion blocks have inclined surfaces, the sliding plate moves so that the inclined surface of the extrusion block pushes the push rod to slide, and the push rod squeezes the force storage component to store force.

[0007] Beneficial effects: After the clamping piece clamps the profile, it pushes the cylinder to drive the sliding plate to move. The inclined surfaces on the extrusion blocks on both sides will simultaneously push the push rods on both sides. The push rods drive the extrusion plates to slide and compress the force storage piece to store force. After the sawing knife cuts the profile, the force of the force storage piece is released, and the moving platforms on both sides will respectively drive the two sections of the profile to move a certain distance to both sides at the same time to avoid the contact between the end face of the cut profile and the sawing knife. As the sawing knife continues to move, the subsequent multiple profiles are gradually cut in the same way. Therefore, when the sawing knife continues to move or return, the end face of the profile is prevented from contacting the blade of the sawing knife, which can avoid scratches on the end face of the profile and ensure production quality.

[0008] Preferably, a trapezoidal slider is provided on the bearing plate, a slide groove matching the slider is provided at the bottom of the mounting plate, the slider slides in the slide groove, the slider has a threaded hole extending vertically therethrough, and a fixing bolt is installed in the threaded hole.

[0009] The effect is that the distance between each group of pressing units can be adjusted to be suitable for profiles of different sizes.

[0010] Preferably, a plurality of guide rollers are rotatably mounted on the upper surface of the workbench, and the guide rollers are horizontally spaced and distributed along the left-right direction.

[0011] The effect is that the guide roller is located at the bottom of the profile and can play a conveying role, making it easy for the profile to move to both sides.

[0012] Preferably, two driving grooves are provided on the two opposite inner side walls of the mounting platform, and the two driving grooves on each side wall are horizontally spaced apart from each other, the driving groove has a horizontal section and an arc section, the horizontal section is connected to the arc section, the arc section is bent upward, and movable columns are provided at positions corresponding to the driving grooves on the front and rear sides of the movable platform, and the movable columns are slidably fitted in the driving grooves.

[0013] The effect is that after each profile is cut, the cut section will immediately fall to the unloading module, so that the cut profiles fall one by one, which makes it easy to sort and collect the cut profiles, facilitates subsequent operations, and improves efficiency.

[0014] Preferably, a filter plate is fixedly mounted on the side of the workbench, and the filter plate is arranged obliquely, and a plurality of convex strips with arc-shaped cross-sections are arranged at intervals on the surface of the filter plate along its length direction.

[0015] The effect is that when the profile falls on the filter plate and in the process of rolling down, the debris on the profile can fall through the holes on the filter plate.

[0016] Preferably, a plurality of retaining columns are obliquely distributed along the length direction on the surface of the filter plate.

[0017] Preferably, a force storage chamber is provided on the moving platform, and the force storage member is a spring installed in the force storage chamber.

[0018] Preferably, the pressing piece is made of rubber, and the pressing surface of the pressing piece is an arc-shaped structure.

[0019] By adopting the above technical solution, the beneficial effects of the present invention are as follows: after the clamping part clamps the profile, the cylinder is pushed to drive the sliding plate to move, and the inclined surfaces on the extrusion blocks on both sides will simultaneously push the push rods on both sides, and the push rods drive the extrusion plates to slide and compress the force storage part to store force. After the sawing knife cuts the profile, the force of the force storage part is released, and the moving platforms on both sides will respectively drive the two sections of the profile to move a certain distance to both sides at the same time, so as to avoid the contact between the end face of the cut profile and the sawing knife. As the sawing knife continues to move, the subsequent multiple profiles are gradually cut in the same way. Therefore, when the sawing knife continues to move or returns, the contact between the end face of the profile and the blade of the sawing knife is avoided, which can avoid scratches on the end face of the profile and ensure production quality.

[0020] After the moving column moves to the end of the horizontal section, it will enter the arc section and then move upward along the arc section. When the moving platform moves upward, it will drive the clamping part to lift upward, so that the clamping part releases the restriction on the profile. After each profile is cut, the cut section will immediately fall to the unloading module, so that the cut profiles fall one by one, which makes it easy to sort and collect the cut profiles, facilitate subsequent operations, and improve efficiency.

[0021] By providing the filter plate, when the profile falls on the filter plate and in the process of rolling down, the debris on the profile can fall from the holes on the filter plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The following details the embodiments of the present invention, and the examples of the embodiments are shown in the drawings. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0031] As Figures 1 to 7 shown, a specific embodiment of a profile sawing device of the present invention includes a workbench 10, a cutting module, a conveyor frame 20, a lateral clamping module, a vertical clamping module, and a blanking module.

[0032] As Figure 1 And Figure 2As shown in the figure, the cutting module includes a moving component 11 installed inside the workbench 10. A saw blade 12 is installed on the moving component 11. The moving component 11 can drive the saw blade 12 to move horizontally. At the same time, a driving motor for driving the saw blade 12 to rotate is installed on the moving component 11. A through hole that penetrates up and down is provided at the position corresponding to the saw blade 12 on the upper surface of the workbench 10. The saw blade 12 passes through the through hole and extends above the workbench 10. Thus, the moving component 11 can drive the rotating saw blade 12 to cut the profile. The above structures all belong to the prior art and will not be elaborated here.

[0033] The conveying frame 20 is arranged on one side of the workbench 10. A plurality of conveying rollers are rotatably installed at intervals on the workbench 10. The conveying rollers are used to convey the profile to be processed to the upper surface of the workbench 10. The moving component 11 drives the rotating saw blade 12 to cut the profile.

[0034] In this embodiment, the conveying direction of the profile by the conveying frame 20 is defined as the left - right direction, and the direction in which the moving component 11 drives the saw blade 12 to move is defined as the front - back direction. It should be specifically noted that the profile in this embodiment is a hollow circular tube. In other embodiments, it is not limited to this, and the profile can be of other different shapes.

[0035] The saw blade 12 divides the upper surface of the workbench 10 into two parts, the right part (the side close to the conveying frame 20) is the area to be processed, and the left part is the processed area. A plurality of guide rollers 14 are rotatably installed on the upper surface of the workbench 10 in both the area to be processed and the processed area. And the guide rollers 14 are horizontally spaced along the left - right direction, and the axial directions of the guide rollers 14 are all horizontal with the front - back direction. The guide rollers 14 can facilitate the movement of the profile.

[0036] Continue to refer to Figure 2 , the transverse clamping module includes a clamping cylinder 40 fixedly installed on the upper surface of the workbench 10. A clamping plate 41 is fixedly installed on the telescopic part of the clamping cylinder 40. The clamping cylinder 40 is located at a position near the front end of the area to be processed and can perform transverse clamping and positioning on the profile conveyed to the upper surface of the workbench 10. When the profile is conveyed to the upper surface of the workbench 10, the axial direction of the profile is horizontal with the left - right direction. One end of the profile in the advancing direction is located in the processed area, and the part of the profile to be processed is located in the area to be processed. After the saw blade 12 finishes one - time cutting of the profile, the cut - off part will be in the processed area and then be collected. Then the profile in the area to be processed continues to move forward, and so on in a cycle until the entire sawing work of the profile is completed.

[0037] On the upper surface of the workbench 10, a plurality of mounting holes are provided along the front-back direction, which can adjust the mounting position of the clamping cylinder 40 back and forth, so as to be able to clamp and position profiles in different quantities in the front-back direction. Frictional force is generated between two adjacent profiles, thereby preventing the profiles from moving in the left-right direction.

[0038] As Figures 3 to 6 shown, the vertical clamping module includes a lifting unit, a pressing unit and a pushing unit.

[0039] The lifting unit includes a bracket 13 fixedly installed on the upper surface of the workbench 10. On the upper surface of the bracket 13, a lifting cylinder 50 is fixedly installed. The telescopic part of the lifting cylinder 50 is fixedly installed with a mounting plate 51. The lifting cylinder 50 can drive the mounting plate 51 to lift. In this embodiment, the mounting plate 51 is of a rectangular structure, and its length direction is parallel to the front-back direction.

[0040] The pressing unit is installed on the mounting plate 51, and multiple groups of pressing units are provided. The pressing units are spaced along the front-back direction on the mounting plate 51. Each group of pressing units corresponds to a profile below, so that multiple groups of pressing units can press and fix multiple profiles below.

[0041] Each group of pressing units includes a bearing plate 60 slidably installed at the bottom of the mounting plate 51 along the front-back direction. The bearing plate 60 is of a rectangular structure, and its length direction is parallel to the left-right direction. A trapezoidal slider 61 is provided on the bearing plate 60, and a chute matching the slider 61 is provided at the bottom of the mounting plate 51. The slider 61 is slidably fitted in the chute. The slider 61 has a threaded hole penetrating up and down, and a fixing bolt 62 is installed in the threaded hole. By rotating the fixing bolt 62, the slider 61 and the bearing plate 60 can be fixed. In this way, the distance between each group of pressing units can be adjusted to suit profiles of different sizes.

[0042] In this embodiment, 4 bearing plates 60 are provided along the front-back direction, but the number is not limited to this and is determined according to the number of processed profiles.

[0043] On the left and right sides of the lower surface of the bearing plate 60, two mounting platforms 63 are symmetrically installed. Inside the mounting platforms 63, moving platforms 64 are horizontally slidably installed left and right. A return spring 65 is connected between the mounting platform 63 and the moving platform 64. The two ends of the return spring 65 are respectively fixedly connected to the mounting platform 63 and the moving platform 64.

[0044] At the bottom of each moving platform 64, a connecting column 66 is fixedly installed. At the bottom of the connecting column 66, a pressing member 67 is fixedly installed. In this embodiment, the pressing member 67 is made of rubber, and the pressing surface is an arc structure matching the profile.

[0045] The two mounting platforms 63 on each carrier plate 60 are respectively located in the area to be processed and the area where processing is completed. When the lifting cylinder 50 drives the mounting plate 51 to descend, the pressing members 67 on the left and right sides of each carrier plate 60 can be pressed against two areas on the corresponding profile below (such as Figure 1 ).

[0046] In the horizontal direction of the profile, there is a clamping plate 41 to limit it. The clamping plate 41 can push the profile onto the bracket 13. In the vertical direction of the profile, there is a pressing member 67 to limit it. Therefore, the profile can be firmly restricted and will not move.

[0047] It should be particularly emphasized that although the moving platform 64 is slidably engaged with the mounting platform 63, the clamping of the profile by the clamping plate 41 will generate frictional force between the profiles, that is, a pre-tightening force is applied to the profiles. At the same time, there is a return spring 65 between the mounting platform 63 and the moving platform 64, and the return spring 65 will also limit the movement of the moving platform 64. Therefore, when the pressing member 67 presses down on the profile, the moving platform 64 will not slide on the mounting platform 63.

[0048] A power storage assembly is provided on each moving platform 64. After the pressing member 67 presses down on the profile, the power storage assembly is charged through the pushing unit. The power storage assembly will generate a force to push the moving platform 64 to move. The two moving platforms 64 on each carrier plate 60 will move to both sides respectively, but this force acts on the profile. Since the pressing member 67 presses on the profile, the power storage assembly will not be released. After the sawing blade 12 cuts the profile, the power storage assembly will overcome the frictional force (pre-tightening force) generated between the profiles, and the two moving platforms 64 will drive the two cut parts of the profile to move to both sides simultaneously.

[0049] Continuing back to Figure 4 , the power storage assembly includes a power storage cavity 70 opened on the moving platform 64. A power storage member 71 is installed in the power storage cavity 70. In this embodiment, the power storage member 71 is a spring. A pressing plate 72 is slidably installed on one side of the power storage cavity 70 close to the center position. A push rod 73 is fixedly installed on the side of the pressing plate 72 away from the power storage member 71. The push rod 73 extends to the outside of the power storage cavity 70, and the push rods 73 on the two relatively left and right moving platforms 64 are arranged oppositely.

[0050] Such as Figure 5 shown, the pushing unit includes a pushing cylinder 80 fixedly installed on the front side of the mounting plate 51. A sliding plate 81 is fixedly installed on the telescopic part of the pushing cylinder 80. The sliding plate 81 is horizontally slidably installed on the mounting plate 51 in the front and back directions.

[0051] The sliding plate 81 is arranged in the front-rear direction and is located at the middle position between the two moving platforms 64 on both sides. Extrusion blocks 82 are fixedly installed on both the left and right side surfaces of the sliding plate 81, and the extrusion blocks 82 on the left and right sides of the sliding plate 81 are symmetrically arranged. One surface of the extrusion block 82 away from the sliding plate 81 has a horizontal surface 83 and an inclined surface 84. In the initial state, the push rod 73 abuts against the horizontal surface 83.

[0052] After the pressing member 67 presses the profile downward, the pushing cylinder 80 drives the sliding plate 81 to move backward. At this time, the inclined surfaces 84 on the extrusion blocks 82 on both sides will simultaneously push the push rods 73 on both sides. The push rods 73 drive the extrusion plate 72 to slide and compress the energy storage member 71 to store energy. Since the two relatively pressing members 67 are both pressed on the same profile, and at the same time, the elastic force of the energy storage member 71 is less than the frictional force between the pressing member 67 and the profile, the energy storage members 71 on both sides are in a state of waiting to be released.

[0053] After the saw blade 12 cuts off the profile, the force of the energy storage member 71 is released. It should be particularly noted that the force of the energy storage member 71 is greater than the elastic force of the return spring 65, and at the same time, the force of the energy storage member 71 is greater than the frictional force (pre-tightening force) generated between the profiles. Therefore, the moving platforms 64 on both sides will drive the two sections of the profile to move a certain distance to the left and right sides respectively, avoiding the end face of the cut profile from contacting the saw blade 12, and the return spring 65 will be stretched. Similarly, as the saw blade 12 continues to move, subsequent multiple profiles will be gradually cut in the same way. The guide roller 14 is located at the bottom of the profile and can play a conveying role to facilitate the movement of the profile to both sides.

[0054] Generally speaking, after the profile is cut, the force of the energy storage member 71 is released, which will quickly drive the two sections of the profile to move to the left and right sides, avoiding contact with the blade surface of the saw blade 12. Thus, when the saw blade 12 continues to move or return, it can avoid causing scratches on the end face of the profile.

[0055] The release of the elastic force of the energy storage member 71 enables the distance that the moving platform 64 drives the profile to move to be set as needed, which can be 1 - 2 cm or longer.

[0056] After the saw blade 12 completes one stroke and finishes cutting all the profiles, the lifting cylinder 50 drives the bearing plate 60 to rise, the pushing cylinder 80 drives the sliding plate 81 to reset, the return spring 65 drives the moving platform 64 to reset, and then continues to push the profile forward. In this cycle, the sawing of the profile is completed. It should be particularly noted that the present invention also includes a pushing mechanism for the profile and a limiting mechanism for the front end of the profile moving forward. The limiting mechanism can ensure that the end parts of all profiles are flush after moving. The pushing mechanism and the limiting mechanism both belong to the prior art and are not shown in the figure.

[0057] As Figure 6As shown, two driving grooves 90 are provided on the two opposite side walls of the inner side of the mounting platform 63 located on the left side (processing completion area), and the two driving grooves 90 on each side wall are arranged horizontally and spaced from each other. The driving groove 90 has a horizontal section 92 and an arc section 93, the horizontal section 92 is connected to the arc section 93, and the arc section 93 is bent upward.

[0058] Moving posts 91 are disposed at positions on both the front and rear sides of the moving platform 64 corresponding to the driving slot 90 , and the moving posts 91 are slidably fitted in the driving slot 90 .

[0059] In the initial state, the movable column 91 is located at the end of the horizontal section 92 . As the movable platform 64 slides in the mounting platform 63 , when the movable column 91 moves to the end of the horizontal section 92 , it enters the arc section 93 and then moves upward along the arc section 93 .

[0060] When the moving platform 64 moves upward, it drives the pressing member 67 to lift upward, so that the pressing member 67 releases the restriction on the profile.

[0061] At this time, the distance that the movable platform 64 pushes the profile is set to be greater than the length of the cut profile, so that the cut profile is not restricted in the horizontal and vertical directions, which facilitates the cut profile to fall into the unloading module.

[0062] Generally speaking, after each profile is cut, the cut section will immediately fall to the unloading module, so that the cut profiles fall one by one, which makes it easy to sort and collect the cut profiles, facilitate subsequent operations, and improve efficiency. It avoids the cut profiles falling at the same time, which increases the labor intensity of workers.

[0063] like Figure 1 and Figure 7 As shown, the unloading module includes a filter plate 30 fixedly mounted on the left side of the workbench 10. The filter plate 30 is tilted, and more debris will remain on the inner side of the cut profile (inner through hole). When the profile falls on the filter plate 30 and rolls down, the debris on the inner side of the profile can fall from the holes on the filter plate 30.

[0064] The filter plate 30 has a plurality of convex strips 31 with arc-shaped cross sections arranged at intervals along its length direction. When the profile rolls down along the filter plate 30 , the profile can be bumped, which facilitates the discharge of debris in the profile.

[0065] The filter plate 30 has a plurality of blocking posts 32 (such as Figure 7 ), when the profile is in a horizontal state (the axial direction of the profile is horizontal with the front and back), it is not conducive to the discharge of the debris inside. The blocking column 32 can play a role in moving the profile, so that the profile is transformed into an inclined or vertical state (the axial direction of the profile is consistent with the falling direction), which is convenient for the discharge of the debris inside the profile.

[0066] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention.
