Description

Technical Field

[0001] This utility model relates to a profile cutting device. Background Technology

[0002] Currently, many household products frequently use aluminum profiles as frames. After forming a circle or rectangle around the aluminum profile, the two ends partially overlap, requiring cutting equipment to remove excess material. Traditional cutting equipment lays the profile flat on a table, uses a pressing mechanism to press and fix it at multiple points before cutting. However, during the cutting or positioning process, the shape and dimensions of the profile can easily change, resulting in uneven cuts that affect subsequent production and ultimately impact product yield. Furthermore, for rolled profiles of different diameters or rectangular profiles with varying side lengths, the position of the pressing mechanism needs repeated adjustments, making it inconvenient for cutting products of different specifications.

[0028] See Figures 1 to 3This utility model discloses a profile cutting device, comprising: a worktable 100, on which a support 200 is provided for supporting the overlapping portion of a vertically placed profile workpiece 10 exceeding one circumference; a positioning bracket 300, disposed on the worktable 100, for supporting the vertically placed profile workpiece 10, wherein at least three non-collinear positioning components 400 are movably disposed on the positioning bracket 300, and the left, right, and top sides of the profile workpiece 10 respectively abut against at least one of the positioning components 400; a pressing and fixing mechanism 500, movably disposed above the support 200, for pressing the overlapping portion of the profile workpiece 10 exceeding one circumference downward onto the support 200; and a cutting mechanism 600, movably and vertically disposed on the worktable 100, for cutting off the overlapping portion of the profile workpiece 10 exceeding one circumference.

[0029] The profile cutting equipment with the above structure uses a positioning bracket 300 and a support 200 to jointly support a vertically placed profile workpiece 10 that wraps around the entire body more than once. At least three positioning components 400 and the support 200 respectively contact the left, right, top, and bottom sides of the profile workpiece 10. Then, the cutting mechanism 600 cuts off the overlapping part of the profile workpiece 10 that wraps around the entire body, thereby accurately positioning the profile workpiece 10 and ensuring the shape of the cut and the dimensional accuracy of the cut. The positioning components 400 can move relative to the positioning bracket 300 to adapt to cutting profile workpieces 10 of different sizes and specifications, thereby improving the versatility of the profile cutting equipment.

[0030] See Figure 2In some embodiments of this utility model, the support 200 includes a left seat 210 and a right seat 220 spaced apart from each other. The left seat 210 and the right seat 220 are respectively provided with a first support surface 211 and a second support surface 221 that fit against the bottom outer wall of the profile workpiece 10. The cutting mechanism 600 includes a lifting seat that is lifted and lowered on the worktable 100, a motor provided on the lifting seat, and a saw gear driven by the motor. The worktable 100 is provided with a clearance through hole groove 110 located between the left seat 210 and the right seat 220. The saw gear can extend upward from the clearance through hole groove 110 to cut off more than one circle of overlapping portion of the profile workpiece 10. Understandably, the left half of the overlapping portion of the profile workpiece 10 (exceeding one circumference) is placed on the first support surface 211, and the right half of the overlapping portion of the profile workpiece 10 (exceeding one circumference) is placed on the second support surface 221. The pressing and fixing mechanism 500 presses the profile workpiece 10 located on both sides of the saw gear onto the left seat 210 and the right seat 220. As the lifting seat rises, the saw gear driven by the motor extends upward from the clearance through-hole groove 110 to cut off the portion of the profile workpiece 10 that exceeds one circumference. At this time, the two end faces of the profile workpiece 10 can fit together, facilitating subsequent welding and fixing. In this embodiment, the pressing and fixing mechanism 500 includes two pressing cylinders that are respectively raised and lowered above the left seat 210 and the right seat 220.

[0031] See Figure 1 and Figure 2 In some embodiments of this utility model, the first support surface 211 and the second support surface 221 are both concave arc surfaces, and the left seat 210 and the right seat 220 are detachably mounted on the worktable 100. It is understood that when the profile workpiece 10 is wound into a circle, the profile workpiece 10 has an arc portion exceeding one circle. The first support surface 211 and the second support surface 221 are both concave arc surfaces to fit the circularly wound profile workpiece 10, ensuring a secure fixation effect on the profile workpiece 10, thereby ensuring a smooth cut and high dimensional accuracy after cutting. Furthermore, since the left seat 210 and the right seat 220 are detachably mounted on the worktable 100, it can adapt to processing profile workpieces 10 with different diameters. Of course, in other embodiments, see... Figure 3 When the profile workpiece 10 is wrapped around to form a rectangular frame, the first support surface 211 and the second support surface 221 are planes.

[0032] See Figures 1 to 3In some embodiments of this utility model, both the left seat 210 and the right seat 220 are provided with a front limiting plate 710 and a rear limiting plate 720 to prevent the overlapping portion of the profile workpiece 10 from moving back and forth beyond one revolution. The front limiting plate 710, the rear limiting plate 720, the first support surface 211, and the second support surface 221 together form a limiting space. It can be understood that the positioning component 400 and the support 200 only limit the profile workpiece 10 in the vertical and horizontal directions. The profile workpiece 10 may move in the back and forth direction. The front limiting plate 710 and the rear limiting plate 720 solve the problem of the profile workpiece 10 moving back and forth, further ensuring the cutting accuracy.

[0033] See Figure 2 and Figure 4 In this embodiment, the upper surface of the workbench 100 is also provided with a base plate 120. The rear limiting plate 720 and the support 200 are both fixed to the upper surface of the base plate 120, while the front limiting plate 710 is detachably installed on the front end face of the base plate. Depending on the profile workpiece 10 with different widths, different shapes and sizes of the front limiting plate 710 can be replaced to clamp and position the overlapping portion of the profile workpiece 10 beyond one circumference between the front limiting plate 710 and the rear limiting plate 720. For example, when the overlapping portion of the profile workpiece 10 beyond one circumference... Figure 1 When the front-to-back dimension of the coordinate system is less than the distance between the front limiting plate 710 and the rear limiting plate 720, the front limiting plate 710 is replaced with a stepped shape. Specifically, the front limiting plate 710 includes a first vertical plate 711 fixed to the front end face of the base plate 120, a horizontal plate 712 connected to the upper end of the first vertical plate 711 and extending rearward, and a second vertical plate 713 connected to the rear end of the horizontal plate. The second vertical plate 713 abuts against the side wall of the overlapping portion of the profile workpiece 10 exceeding one circumference. Similarly, when the overlapping portion of the profile workpiece 10 exceeds one circumference along... Figure 1 When the longitudinal dimension of the coordinate system is greater than the distance between the front limiting plate 710 and the rear limiting plate 720, the front limiting plate 710 includes a first vertical plate fixed to the front end face of the base plate, a horizontal plate connected to the upper end of the first vertical plate and extending forward, and a second vertical plate connected to the front end of the horizontal plate. The second vertical plate abuts against the side wall of the overlapping portion of the profile workpiece 10 for more than one circumference. To avoid interference between the support 200 and the front limiting plate 710, the longitudinal dimension of the support 200 should be less than the distance between the first vertical plate and the rear limiting plate 720.

[0034] In some embodiments of this utility model, in order to facilitate the placement of the profile workpiece 10 between the front limiting plate 710 and the rear limiting plate 720, the upper ends of the front limiting plate 710 and the rear limiting plate 720 are provided with arc guide angles for guiding the profile workpiece 10 downward into the limiting space.

[0035] See Figure 1 In some embodiments of this utility model, the positioning bracket 300 includes a vertical beam 310 fixed to the workbench 100 and a horizontal beam 320 orthogonal to the vertical beam 310. A positioning component 400 is slidably and vertically mounted on the upper part of the vertical beam 310, and a positioning component 400 is slidably mounted on each end of the horizontal beam 320 along its length. Both the vertical beam 310 and the horizontal beam 320 are provided with a scale 800 extending along their length. The scale 800 allows the user to move each positioning component 400 into position according to the specific dimensions of the profile workpiece 10, avoiding excessive compression of the profile workpiece 10 after the positioning components 400 are moved.

[0036] In some embodiments of this utility model, the vertical beam 310 and the horizontal beam 320 are made of magnetic material. The positioning component 400 includes an adjusting seat and a magnetic suction member rotatably disposed on the adjusting seat. The magnetic suction member can rotate to attract and fix the adjusting seat to the vertical beam 310 or the horizontal beam 320, and the magnetic suction member can also rotate to detach the adjusting seat from the vertical beam 310 or the horizontal beam 320. The positioning component 400 with the above structure is a switch-type magnetic seat. The switch-type magnetic seat can attract or detach the magnetic material by rotating 90° in both directions, which is very convenient to use. Specifically, the magnetic attractor is a bar magnet with N and S poles. When the bar magnet is parallel to the surface of the vertical beam 310 or the horizontal beam 320, the magnetic lines of force emitted by the N pole of the bar magnet can pass through the vertical beam 310 or the horizontal beam 320 and return to the S pole, thereby generating a magnetic attraction force. When the bar magnet is perpendicular to the surface of the vertical beam 310 or the horizontal beam 320, the magnetic attraction force is lost. The switchable magnetic base is a product of the prior art and will not be described in further detail here.

[0037] See Figure 1 In some embodiments of this utility model, to prevent the profile workpiece 10 from tilting forward, the adjusting seat located on the vertical beam 310 is also provided with an open receiving groove 410 adapted to the profile workpiece 10 and a rotary clamping cylinder 420 movably disposed at the opening of the receiving groove 410. It can be understood that the rotary clamping cylinder 420 can be rotated to open the opening of the receiving groove 410 so that the profile workpiece 10 can be placed into the receiving groove 410, and then the rotary clamping cylinder 420 can be rotated to the opening of the receiving groove 410 and press the profile workpiece 10 against the bottom of the receiving groove 410, thereby positioning and fixing the profile workpiece 10.

[0038] See Figure 1In some embodiments of this utility model, the crossbeam 320 is connected to the vertical beam 310 via a lifting adjustment mechanism 900. It should be noted that, for a profile workpiece 10 arranged in a circle, in order to ensure that the two positioning components 400 on the crossbeam 320 can clamp the profile workpiece 10 radially and avoid loss of roundness, the lifting adjustment mechanism 900 is needed to adjust the height of the crossbeam 320 to the correct position. For a profile workpiece 10 with a roughly rectangular frame, the lifting adjustment mechanism 900 can also move the two positioning components 400 on the crossbeam 320 to the middle position in the height direction of the profile workpiece 10, thereby ensuring the effectiveness of multiple positioning components 400 in cooperating with the support 200 to position the profile workpiece 10.

[0039] See Figure 1 In some embodiments of this utility model, the vertical beam 310 is provided with a sliding guide groove 311 along its height direction, and the middle part of the horizontal beam 320 is provided with a slider part that can reciprocate and move up and down in the sliding guide groove 311. The lifting adjustment mechanism 900 includes a fastening bolt 910 passing through the horizontal beam 320 and a plurality of positioning holes 920 spaced apart along the height direction of the vertical beam 310. The fastening bolt 910 is correspondingly connected to one of the positioning holes 920 to adjust the height position of the horizontal beam 320. It can be understood that when it is necessary to adjust the relative height position of the horizontal beam 320 on the vertical beam 310, the fastening bolt 910 is first loosened, and then the horizontal beam 320 is driven to move up and down until the fastening bolt 910 is aligned with the corresponding positioning hole 920. During this process, the slider part slides up and down in the sliding guide groove 311, and then the fastening bolt 910 is connected to the positioning hole 920. It should be noted that the positioning holes 920 at different heights correspond to profile workpieces 10 of different sizes and specifications. Of course, in other embodiments, the positioning holes 920 can be eliminated, and the fastening bolts 910 can be directly tightened onto the vertical beam 310 to accommodate profile workpieces 10 with more size variations.

[0040] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0041] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
