Description

Technical Field

[0001] This application relates to the field of profile processing equipment technology, and in particular to a shearing device for industrial profile production. Background Technology

[0002] Profiles are objects with a certain geometric shape made of iron or steel and other materials with a certain strength and toughness through processes such as rolling, extrusion, and casting. These materials have a fixed external dimension, a certain cross-sectional shape, and certain mechanical and physical properties, and are often used in building structures and equipment manufacturing and installation.

[0003] Currently, the shearing devices with fixed-length shearing function used in the market have low working efficiency. As a result, shearing devices with fixed-length shearing function for general profiles generally require manual operation, which increases the labor consumption of users and the processing time. Therefore, it needs to be improved. Summary of the Invention

[0004] To improve the problem of low shearing efficiency when shearing profiles to a fixed length, this application provides a shearing device for industrial profile production.

[0005] The shearing device for industrial profile production provided in this application adopts the following technical solution:

[0006] A shearing device for industrial profile production includes a cutting platform, a support plate slidably mounted on the cutting platform, baffles provided at the four corners of the support plate, the support plate and the baffles forming a cavity for placing the profile, and the cutting platform is provided with a first unidirectional pushing mechanism for intermittently driving the support plate to move a fixed length and a cutting mechanism for cutting the profile.

[0007] By adopting the above technical solution, when cutting the profile, the profile is placed in the cavity formed by the support plate and four baffles to limit the profile. Then, under the action of the first one-way pushing mechanism, the support plate is pushed to move a fixed length. After that, the cutting mechanism cuts the profile to a fixed length. This method of automatically pushing the profile to move and automatically cutting the profile can effectively improve the problem of low cutting efficiency when cutting the profile to a fixed length.

[0008] Optionally, the first unidirectional pushing mechanism includes two sets of positioning structures disposed on the surface of the support plate. The two sets of positioning structures are respectively located on both sides of the surface of the support plate and along the moving direction of the support plate. Each set of positioning structures includes a plurality of equally spaced positioning holes.

[0009] The first unidirectional pushing mechanism also includes two positioning claws, which correspond one-to-one with the two sets of positioning structures, and the positioning claws are movably inserted into one of the positioning holes on one side.

[0010] The first unidirectional pushing mechanism further includes a driving component for driving the positioning claw to intermittently insert into the positioning hole and push the support plate to move. When the support plate moves toward the cutting mechanism, the positioning claw is inserted into one of the positioning holes and pushes the support plate to move under the action of the driving component. When the positioning claw disengages from the positioning hole, the cutting mechanism cuts the profile.

[0011] By adopting the above technical solution, specifically, when the support plate is moved, the two positioning claws automatically insert into the corresponding positioning holes. At this time, under the action of the drive component, the positioning claws push the support plate to move towards the cutting mechanism. After moving a quantitative displacement, the drive component drives the positioning claws to disengage from the corresponding positioning holes. At this time, the support plate and the profile on it are in a stationary stage, and the cutting mechanism performs quantitative cutting on the profile. After the cutting is completed, the positioning claws continue to be inserted into another positioning hole, and the above operation is repeated, realizing the fixed-length movement and fixed-length cutting of the profile.

[0012] Optionally, the drive assembly includes a slide rail fixed to the cutting platform, the length direction of the slide rail being consistent with the sliding direction of the support plate, a slide bar slidably embedded in the slide rail, a positioning claw rotatably mounted on the slide bar, and a limit rod provided on the slide bar, the side of the positioning claw away from the cutting mechanism movably abutting against the limit rod, and the drive assembly further includes a drive component for driving the slide bar to reciprocate;

[0013] When the slide bar moves toward the cutting mechanism, the positioning claw is inserted into one of the positioning holes; when the slide bar moves away from the cutting mechanism, the positioning claw disengages from the positioning hole.

[0014] By adopting the above technical solution, furthermore, when the support plate is moved, the positioning claw is inserted into the positioning hole under the action of gravity. Then, the driving component drives the slide bar to move in the direction of the cutting mechanism. The limiting rod restricts the reverse rotation of the positioning claw, so that the positioning claw pushes the support plate forward. When the slide bar slides to the maximum stroke, the support plate stops. At this time, the cutting mechanism cuts the profile. Then, the driving component drives the slide bar to move in the opposite direction. When it moves, the positioning claw disengages from the positioning hole. When the slide bar slides to the maximum stroke in the opposite direction, the positioning claw is inserted into another positioning hole under the action of gravity. This process is repeated to achieve fixed-length movement of the profile and improve work efficiency.

[0015] Optionally, the cutting mechanism includes a positioning frame vertically mounted on the cutting platform and a cutting component vertically slidably mounted on the positioning frame, and also includes a lifting assembly for driving the cutting component to reciprocate up and down.

[0016] By adopting the above technical solution, the positioning frame restricts the cutting parts to only vertical lifting movements, and the cutting of profiles is realized under the action of the lifting component.

[0017] Optionally, the lifting assembly includes a rope frame disposed on the cutting platform and a reversing rope disposed on the rope frame. One end of the reversing rope is fixed to the slide bar, and the other end of the reversing rope is fixed to a first rack. The first rack is vertically slidably mounted on the positioning frame. A second rack is vertically disposed on the cutting piece. The second rack is vertically slidably mounted on the positioning frame. A gear is also rotatably mounted on the positioning frame. The gear meshes with the first rack and the second rack respectively.

[0018] When the slider moves away from the cutting element, the first rack rises, and the second rack and the cutting element descend.

[0019] By adopting the above technical solution, when the slider moves away from the cutting part under the action of the drive component, the slider pulls the reversing rope on the rope frame to move. At this time, the reversing rope pulls the first rack to rise. When the first rack rises, the gear rotates. When the gear rotates, it drives the second rack to fall and simultaneously drives the cutting part to fall, thus realizing the cutting of the profile.

[0020] Optionally, the cutting platform is provided with a second one-way pushing mechanism for driving the support plate to move a fixed length, wherein the direction of movement of the support plate driven by the first one-way pushing mechanism is opposite to the direction of movement of the support plate driven by the second one-way pushing mechanism.

[0021] By adopting the above technical solution, the second unidirectional pushing mechanism enables the profile to be fed and moved for cutting from two directions, improving the practicality and versatility of the device.

[0022] Optionally, the cutting platform is provided with multiple pressure strips for restricting the vertical movement of the profile.

[0023] By adopting the above technical solution, the setting of the pressure strip for pressing the profile restricts the vertical movement of the profile during cutting, thereby improving the stability of profile cutting.

[0024] Optionally, the support plate is provided with clamping components on opposite sides along its moving direction for clamping the profile.

[0025] By adopting the above technical solution, the clamping components further fix the profile, making it stable during transmission and cutting.

[0026] Optionally, the support plate is provided with a support ball for supporting the profile near the baffle.

[0027] By adopting the above technical solution, the support ball supports the support plate, raises the support plate and keeps it at a distance from the plate surface, which facilitates the cutting parts to cut the profile and improves the cutting effect.

[0028] Optionally, the support plate has a perforation, and the cutting platform has a discharge port for the cut profile to be discharged.

[0029] When the support plate moves to the discharge port, the cut profile passes through the perforation and the discharge port for discharge.

[0030] By adopting the above technical solution, the cutting component cuts the profile and the profile falls onto the cutting platform. Under the action of the support plate, it continues to move forward. When the perforation is opposite to the blanking hole, the profile is blanked.

[0031] In summary, this application includes at least one of the following beneficial technical effects:

[0032] 1. When cutting the profile, the profile is placed in the cavity formed by the support plate and four baffles to limit the profile. Then, under the action of the first one-way pushing mechanism, the support plate is pushed to move a fixed length. Then the cutting mechanism cuts the profile to a fixed length. This automatic pushing and automatic cutting method can effectively improve the problem of low cutting efficiency when cutting the profile to a fixed length.

[0033] 2. When the support plate is moved, the positioning claws are inserted into the positioning holes under the action of gravity. Then, the drive component drives the slide bar to move in the direction of the cutting mechanism. The limit rod restricts the reverse rotation of the positioning claws, so that the positioning claws push the support plate forward. When the slide bar slides to the maximum stroke, the support plate stops. At this time, the cutting mechanism cuts the profile. Then, the drive component drives the slide bar to move in the opposite direction. When it moves, the positioning claws disengage from the positioning holes. When the slide bar slides to the maximum stroke in the opposite direction, the positioning claws are inserted into another positioning hole under the action of gravity. This process is repeated to achieve fixed-length movement of the profile and improve work efficiency.

[0034] 3. When the slider moves away from the cutting part under the action of the drive component, the slider pulls the reversing rope on the rope frame to move. At this time, the reversing rope pulls the first rack to rise. When the first rack rises, the gear rotates. When the gear rotates, it drives the second rack to fall and simultaneously drives the cutting part to fall, thus realizing the cutting of the profile. Attached Figure Description

[0040] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0041] This application discloses a shearing device for industrial profile production.

[0042] Reference Figure 1 and Figure 2 A shearing device for industrial profile production includes a cutting platform 1, which is rectangular in shape. A support plate 2, also rectangular, is slidably mounted on the cutting platform 1 along its length, with its length aligned with that of the cutting platform 1. Four L-shaped baffles 3 are fixed to the surface of the support plate 2, arranged in a rectangular pattern. These baffles, together with the support plate 2, form a cavity for placing the profile. A support ball 9 is fixed near each baffle 3 on the support plate 2, and the profile is placed on the four support balls 9. The cutting platform 1 is equipped with a first unidirectional pushing mechanism 4 for intermittently driving the support plate 2 to move a fixed length and a cutting mechanism 5 for cutting the profile. The support balls 9 support the support plate 2, raising it and maintaining a distance from its surface, facilitating the cutting mechanism 5 in cutting the profile and improving the cutting effect.

[0043] Reference Figure 1The first one-way pushing mechanism 4 includes two sets of positioning structures 41 disposed outside the accommodating cavity of the support plate 2. The two sets of positioning structures 41 are respectively located on the surface of the support plate 2 and on both sides along the length direction of the support plate 2. Each set of positioning structures 41 includes a plurality of equally spaced positioning holes 411. The first one-way pushing mechanism 4 also includes two positioning claws 42, which correspond one-to-one with the two sets of positioning structures 41, and the positioning claws 42 are movably inserted into one of the positioning holes 411 on one side. The first one-way pushing mechanism 4 also includes a driving component 43 for driving the positioning claws 42 to intermittently insert into the positioning holes 411 and push the support plate 2 to move.

[0044] Reference Figure 1 Specifically, the drive assembly 43 includes a slide rail 431 fixed on the cutting platform 1. The length direction of the slide rail 431 is consistent with the length direction of the support plate 2. A slide bar 432 is slidably embedded in the slide rail 431. A positioning claw 42 is rotatably mounted on the slide bar 432, and the rotation axis of the positioning claw 42 is consistent with the width direction of the support plate 2. A limit rod 433 is also fixed on the slide bar 432, and the side of the positioning claw 42 away from the cutting mechanism 5 is movably abutting against the limit rod 433. The setting of the limit rod 433 limits the rotation angle of the positioning claw 42. In addition, the drive assembly 43 also includes a drive member 434 for driving the slide bar 432 to reciprocate within the slide rail 431.

[0045] Reference Figure 1 The driving component 434 can be a linkage structure or a cylinder. In this embodiment, the driving component 434 is a linkage structure. Specifically, a first linkage 4341 is rotatably connected to the slide bar 432. The rotation axis of the first linkage 4341 is parallel to the rotation axis of the positioning claw 42. A second linkage 4342 is rotatably connected to the end of the first linkage 4341 away from the slide bar 432. A motor 4343 mounted on the cutting platform 1 is connected to the free end of the second linkage 4342. The length of the first linkage 4341 is greater than the length of the second linkage 4342. When the motor 4343 is started, it drives the second linkage 4342 to rotate. The second linkage 4342 drives the slide bar 432 to slide on the slide rail 431 through the first linkage 4341.

[0046] When the support plate 2 is moved, the positioning claw 42 is inserted into the positioning hole 411 under the action of gravity. Then, through the cooperation of the first connecting rod 4341, the second connecting rod 4342 and the motor 4343, the slide bar 432 is driven to move towards the cutting mechanism 5. The limiting rod 433 restricts the reverse rotation of the positioning claw 42, so that the positioning claw 42 pushes the support plate 2 forward. When the slide bar 432 slides to the maximum stroke, the support plate 2 stops. At this time, the cutting mechanism 5 cuts the profile. Then the slide bar 432 moves in the reverse direction. When it moves, the positioning claw 42 disengages from the positioning hole 411. When the slide bar 432 slides to the maximum stroke in the reverse direction, the positioning claw 42 is inserted into another positioning hole 411 under the action of gravity. This process is repeated to achieve the fixed length movement of the profile and improve work efficiency.

[0047] Reference Figure 1 and Figure 3 The cutting mechanism 5 includes a positioning frame 51 vertically fixed on the cutting platform 1. The positioning frame 51 is a gantry frame. A cutting component 52 and a lifting assembly 53 for driving the cutting component 52 to rise and fall are vertically slidably mounted between opposite sides of the positioning frame 51. The cutting component 52 includes a mounting plate 521 and an automatic cutting blade 522 located on the mounting plate 521.

[0048] Reference Figure 1 and Figure 3 The lifting assembly 53 includes a rope frame 531 fixed on the cutting platform 1 and a deflecting rope 532 mounted on the rope frame 531. One end of the deflecting rope 532 is fixed to a slide bar 432, and the other end of the deflecting rope 532 is fixed to a first rack 533. The deflecting rope 532 is always in a taut state. The first rack 533 is vertically slidably mounted on the positioning frame 51. Second racks 534 are vertically fixed on opposite sides of the mounting plate 521. The two second racks 534 are vertically slidably mounted on the positioning frame 51. On opposite sides, gears 535 are rotatably mounted on the positioning frame 51. Gears 535 mesh with the first rack 533 and the second rack 534 adjacent to the first rack 533 respectively. When the slide bar 432 moves away from the cutting piece 52, the reversing rope 532 pulls the first rack 533 to move vertically upward. At this time, the first rack 533 drives the gear 535 to rotate, and the gear 535 drives the second rack 534 to descend, thereby realizing the descent of the cutting piece 52 and realizing the cutting of the profile.

[0049] Reference Figure 1To improve the stability of the profile, multiple pressure strips 7 are fixed at intervals along the length of the cutting platform 1 for pressing the surface of the profile, and the positions of the pressure strips 7 are offset from the positions of the profile to be cut. Furthermore, clamping assemblies 8 for holding the profile are provided on opposite sides of the support plate 2 along its moving direction. The clamping assembly 8 includes multiple drive cylinders 82 fixed at intervals on the support plate 2 and clamping plates 81 fixed on the drive cylinders 82, with the clamping plates 81 abutting against the profile.

[0050] Reference Figure 1 and Figure 4 The cutting platform 1 is equipped with a second one-way pushing mechanism 6 for driving the support plate 2 to move a fixed length. The second one-way pushing mechanism 6 has the same structure as the first one-way pushing mechanism 4, but the actuation direction of the positioning claws 42 is opposite. That is, the movement direction of the support plate 2 driven by the first one-way pushing mechanism 4 is opposite to the movement direction of the support plate 2 driven by the second one-way pushing mechanism 6. The second one-way pushing mechanism 6 allows the profile to be fed and moved for cutting from two directions, improving the practicality and versatility of the device.

[0051] When the first one-way pushing mechanism 4 is needed, the positioning claw 42 of the second one-way pushing mechanism 6 is lifted to avoid interference with the support plate 2; when the second one-way pushing mechanism 6 is needed, the positioning claw 42 of the first one-way pushing mechanism 4 is lifted and the motors 4343 of the first one-way pushing mechanism 4 and the second one-way pushing mechanism 6 are started at the same time. The support plate 2 is moved by the second one-way pushing mechanism 6 and the cutting piece 52 is driven to rise and fall by the first one-way pushing mechanism 4.

[0052] Reference Figure 1 and Figure 4 The support plate 2 has a through hole 10, and the cutting platform 1 has a material drop port 11 at both ends. A position sensor 12 is installed at the material drop port 11 on the cutting platform 1, and the position sensor 12 is electrically connected to the drive cylinder 82. After the cutting part 52 cuts the profile, the profile falls onto the cutting platform 1 and continues to move forward under the action of the support plate 2. When the through hole 10 is opposite to the material drop port 11, the position sensor 12 detects the position of the support plate 2, and the drive cylinder 82 drives the clamping plate 81 away from the profile, and the profile is dropped.

[0053] The implementation principle of a shearing device for industrial profile production according to an embodiment of this application is as follows: When cutting the profile, the profile is placed in the cavity surrounded by the support plate 2 and the baffle 3, and the support plate 2 is fixed by the pressure strip 7 and the clamping assembly 8. Then, the slide bar 432 moves towards the cutting part 52 under the action of the motor 4343, the first connecting rod 4341 and the second connecting rod 4342. At this time, the positioning claw 42 inserted in the positioning hole 411 pushes the support plate 2 to slide forward. When the slide bar 432 slides to the maximum stroke, the support plate 2 stops, and then the slide bar 432 moves forward. 32 moves in the opposite direction, the positioning claw 42 disengages from the positioning hole 411, and when the slide bar 432 moves, it drives the reversing rope 532 to move. The reversing rope 532 drives the first rack 533 to rise, the first rack 533 drives the gear 535 to rotate, and the gear 535 drives the second rack 534 to descend, thereby realizing the automatic cutting blade 522 cutting the profile. When the slide bar 432 slides to the maximum reverse stroke, the positioning claw 42 is inserted into another positioning hole 411 under the action of gravity. This process is repeated to realize the fixed-length movement and fixed-length cutting of the profile, thereby improving work efficiency.

[0054] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
