Description

Technical Field

[0001] This invention relates to the field of cutting equipment, and more specifically, to a cutting device for sheet metal. Background Technology

[0002] Fiberglass, or fiberglass reinforced plastic, is a composite material using glass fiber as reinforcement and polymer as the matrix. It is widely used in the hull structure of fiberglass boats, often in the form of laminates or sandwich panels. It features high specific modulus and high specific strength, and its excellent designability allows it to meet the mechanical performance requirements of various parts of the hull. To test the mechanical properties of fiberglass laminates or sandwich panels under tension, compression, bending, and shear conditions, the testing center needs to cut pre-formed fiberglass sheets from the shipyard into a series of specimens of specified dimensions according to the relevant testing standards recognized by the China Classification Society.

[0003] However, existing cutting devices have at least the following drawbacks:

[0004] 1. Existing technology makes it difficult to control the precision of fiberglass cutting. The cutting direction is mostly unidirectional, requiring manual adjustment of the fiberglass. This not only makes it difficult to control the cutting precision of fiberglass but also increases the difficulty of operation for personnel.

[0073] Although the invention can be readily embodied in various forms, only some specific embodiments are shown in the accompanying drawings and will be described in detail in this specification. It is understood that this specification should be regarded as an exemplary illustration of the principles of the invention and is not intended to limit the invention to what is described herein.

[0074] Therefore, a feature pointed out in this specification is used to illustrate one feature of one embodiment of the invention, and does not imply that every embodiment of the invention must have the described feature. Furthermore, it should be noted that this specification describes many features. While certain features may be combined to illustrate possible system designs, these features may also be used in other combinations not explicitly stated. Therefore, unless otherwise stated, the described combinations are not intended to be limiting.

[0075] In the embodiments shown in the accompanying drawings, the directional indications (such as up, down, left, right, front, and back) used to explain the structure and movement of the various elements of the invention are relative rather than absolute. These descriptions are appropriate when these elements are in the positions shown in the drawings. If the descriptions of the positions of these elements change, these directional indications also change accordingly.

[0076] Please see Figure 1 and Figure 6 An embodiment of the present invention provides a cutting device for sheet metal, comprising a base 1, a movable frame 2, a clamping assembly 3, and a cutting assembly 4.

[0077] The movable frame 2 is movably connected to the base 1 along a first direction D1. The clamping assembly 3 is used to clamp the plate onto the base 1. The cutting assembly 4 is movably connected to the movable frame 2 along a second direction D2, which is perpendicular to the first direction D1. The cutting assembly 4 includes a mounting base 41 and a saw blade 42. The saw blade 42 is rotatably connected to the mounting base 41. The mounting base 41 includes a dust cover 411 covering the outside of the saw blade 42, and the dust cover 411 is provided with a dust removal port 4111 for connecting to a negative pressure air source. The mounting base 41 has a first mounting position and a second mounting position.

[0078] In the first installation position, the normal direction of the saw blade 42 is parallel to the second direction D2, so as to make cuts in the first direction D1. In the second installation position, the normal direction of the saw blade 42 is parallel to the first direction D1, so as to make cuts in the second direction D2.

[0079] Through the above structural design, the sheet metal is placed on the base 1, and the clamping component 3 presses the sheet metal firmly onto the base 1, preventing displacement of the sheet metal during cutting. When cutting the sheet metal in the first direction D1, the mounting base 41 is installed in the first installation position, and then the moving frame 2 moves relative to the base 1 in the first direction D1, allowing the saw blade 42 to cut in the first direction D1. When cutting the sheet metal in the second direction D2, the mounting base 41 is installed in the second installation position, and then the cutting component 4 moves relative to the moving frame 2 in the second direction D2, allowing the saw blade 42 to cut in the second direction D2. Cutting the sheet metal can be completed without loosening the clamping component 3 or manually handling and rotating the sheet metal, avoiding the problem of inaccurate positioning after sheet metal rotation affecting cutting accuracy. Furthermore, adjusting the installation position of the cutting component 4 is less labor-intensive than rotating the sheet metal, reducing the difficulty of operation, avoiding repeated adjustments of the sheet metal by operators, simplifying operation steps, saving time, and improving cutting efficiency.

[0080] During the cutting process, the dust removal port 4111 on the dust removal hood 411 can suck away a large amount of dust generated during cutting by connecting to a negative pressure air source, reducing the impact of dust on the working environment and the threat to the health of operators.

[0081] This cutting device can cut a whole composite material sheet into a series of specimens of specified sizes for testing the mechanical properties of composite laminates and sandwich panels such as glass fiber and carbon fiber, including tensile, compressive, bending, and shear properties. The size of the cut specimens can be determined according to the test standards for relevant mechanical properties.

[0082] Please see Figures 1 to 3 The movable frame 2 includes two movable seats 21 arranged opposite each other in the second direction D2. The movable seats 21 are T-shaped. The base 1 has a movable groove 11 on each side of the second direction D2. The movable groove 11 is also T-shaped. The two movable seats 21 are movably disposed in the two movable grooves 11 respectively. When the movable seats 21 move relative to the movable grooves 11, the cutting component 4 on the movable frame 2 moves along the first direction D1.

[0083] The movable frame 2 also includes a first rod 22, a first handle 23, and a washer 24. The first rod 22 includes a first rod portion 221 and a second rod portion 222 coaxially connected, with the diameter of the first rod portion 221 being larger than the diameter of the second rod portion 222. The base 1 has an adjustment groove located on one side of the movable slot 11. The second rod portion 222 passes through the adjustment groove and is screwed to the movable base 21. The first handle 23 is connected to the end of the first rod portion 221 away from the second rod portion 222. The washer 24 is sleeved on the second rod portion 222 and clamped between the side wall of the base 1 with the adjustment groove and the first rod portion 221. By rotating the first rod 22 with the first handle 23, the washer 24 and the movable base 21 clamp the side wall of the base 1 with the adjustment groove, thereby restricting the movement of the movable frame 2. By rotating the first rod 22 with the first handle 23, the washer 24 and the movable base 21 loosen from the side wall of the base 1 with the adjustment groove, allowing the movable frame 2 to move relative to the base 1.

[0084] The movable frame 2 also includes a mounting plate 25, a first guide rod 26, and a first lead screw 27. Both the first guide rod 26 and the first lead screw 27 extend along the second direction D2, and their ends are respectively connected to two movable seats 21. The mounting plate 25 is movably connected to the first guide rod 26 and threadedly connected to the first lead screw 27. By rotating the first lead screw 27, the mounting plate 25 can move relative to the first guide rod 26 and the first lead screw 27 in the second direction D2. The cutting assembly 4 is mounted on the mounting plate 25, thereby driving the cutting assembly 4 to move in the second direction D2.

[0085] The movable frame 2 also includes a first operating handle 28 and a first nut 29. The first operating handle 28 is connected to one end of the first lead screw 27, which facilitates the rotation of the first lead screw 27. The first nut 29 is threadedly connected to the first lead screw 27 and is located between the movable frame 2 and the first operating handle 28. After rotating the first lead screw 27 drives the mounting plate 25 to move the cutting assembly 4 into place, the first lead screw 27 can be locked by rotating the first nut 29 against the movable seat 21.

[0086] Please see Figure 4 and Figure 5 and combined Figure 1 The movable frame 2 is provided with a first marking line 251 and a second marking line 252, with the first marking line 251 parallel to a first direction D1 and the second marking line 252 parallel to a second direction D2. In the first installation position, the mounting base 41 covers the first marking line 251, while the second marking line 252 is exposed outside the mounting base 41. In the second installation position, the mounting base 41 covers the second marking line 252, while the first marking line 251 is exposed outside the mounting base 41.

[0087] The installation position of the mounting base 41 can be easily confirmed by observing the marking lines, thereby facilitating the confirmation of the cutting direction of the saw blade 42. In this embodiment, the first marking line 251 and the second marking line 252 are provided on the mounting plate 25.

[0088] Both the first marking line 251 and the second marking line 252 are slots on the movable frame 2, and the first marking line 251 and the marking line are arranged in a cross shape. In the first installation position, the mounting base 41 covers the first marking line 251 and part of the second marking line 252, leaving the remaining part of the second marking line 252 exposed in the mounting base 41. In the second installation position, the mounting base 41 covers the second marking line 252 and part of the first marking line 251, leaving the remaining part of the first marking line 251 exposed in the mounting base 41.

[0089] Since both the first marking line 251 and the second marking line 252 are slotted, it is convenient to process them when the first marking line 251 and the marking line intersect at a cross shape. Of course, in other embodiments, the first marking line 251 and the second marking line 252 may also be lines of a different color than those on the mounting plate 25.

[0090] Please see Figure 5 and Figure 6 The cutting assembly 4 also includes a drive member 43. The drive member 43 is driven and connected to the saw blade 42, and is also connected to the dust cover 411. The mounting base 41 also includes a base plate 412 and a rotating member 413. One end of the rotating member 413 is a first hinge end 4131, which is hinged to the base plate 412, and the axis of rotation of the first hinge end 4131 is parallel to the first direction D1. One end of the dust cover 411 is a second hinge end 4112, which is hinged to the rotating member 413, and the hinge axis of the second hinge end 4112 is parallel to the second direction D2.

[0091] The driving component 43 can be a motor, which drives the saw blade 42 to rotate for cutting. The rotating component 413 can adjust the tilt angle of the saw blade 42 by rotating the first hinge end 4131 to meet the cutting requirements of different tilt angles of the plate. The dust hood 411 can adjust the cutting depth of the saw blade 42 by rotating the second hinge end 4112 to meet the cutting requirements of plates of different thicknesses.

[0092] Please see Figures 4 to 6In this embodiment, the base plate 412 is bolted to the mounting plate 25. The mounting plate 25 has four locking holes 253, two of which are located on either side of the first marking line 251, and the remaining two are located on either side of the second marking line 252. In the first installation position, the base plate 412 is secured to the two locking holes 253 on either side of the first marking line 251 with two bolts. In the second installation position, the base plate 412 is secured to the two locking holes 253 on either side of the second marking line 252 with two bolts.

[0093] The other end of the rotating member 413 is the first movable end 4132. The base plate 412 is provided with a first arc-shaped groove 4121 that is curved around the rotation axis of the first hinge end 4131. The cutting assembly 4 also includes a first locking member 44. The first locking member 44 is connected to the first movable end 4132 and passes through the first arc-shaped groove 4121. The first locking member 44 can lock the first movable end 4132 and the base plate 412, or the first locking member 44 can move within the first arc-shaped groove 4121 so that the rotating member 413 can rotate relative to the base plate 412.

[0094] The movement of the first locking member 44 within the first arc-shaped groove 4121 stabilizes the rotation trajectory of the rotating member 413. The first locking member 44 can also lock the rotating member 413 to prevent rotation, or release it to allow rotation. The first locking member 44 includes a first locking rod 441 and a first locking nut 442. The first locking rod 441 passes through the first arc-shaped groove 4121, and the first locking nut 442 is threaded onto the first locking rod 441. Rotating the first locking nut 442 can clamp the head of the first locking rod 441 and the first locking nut 442 onto both sides of the first arc-shaped groove 4121, or it can loosen the head of the first locking rod 441 and the first locking nut 442 from both sides of the first arc-shaped groove 4121.

[0095] The other end of the dust cover 411 is the second movable end 4113. The rotating member 413 is provided with a second arc-shaped groove 4133 that is curved around the rotation axis of the second hinge end 4112. The cutting assembly 4 also includes a second locking member 45. The second locking member 45 is connected to the second movable end 4113 and passes through the second arc-shaped groove 4133. The second locking member 45 can lock the second movable end 4113 and the rotating member 413, or the second locking member 45 can move within the second arc-shaped groove 4133 so that the dust cover 411 can rotate relative to the rotating member 413.

[0096] The movement of the second locking member 45 within the second arc-shaped groove 4133 stabilizes the rotation trajectory of the dust collector 411. The second locking member 45 can also lock the dust collector 411 to prevent rotation, or loosen it to allow rotation. The second locking member 45 includes a second locking rod 451 and a second locking nut 452. The second locking rod 451 passes through the second arc-shaped groove 4133, and the second locking nut 452 is threaded onto the second locking rod 451. Rotating the second locking nut 452 can clamp the head of the second locking rod 451 and the second locking nut 452 onto both sides of the second arc-shaped groove 4133, or it can loosen the head of the second locking rod 451 and the second locking nut 452 from both sides of the second arc-shaped groove 4133.

[0097] The first hinge end 4131 is provided with a first rotating shaft. The first movable end 4132 is provided with a transition member 41321, and the two ends of the transition member 41321 are respectively provided with a second rotating shaft and a movable part. The first rotating shaft and the second rotating shaft are located on the same straight line and are respectively hinged to both sides of the base plate 412. The second locking member 45 is connected to the movable part.

[0098] The rotating component 413 is hinged to the base plate 412 by the first and second rotating shafts, making the rotation of the rotating component 413 more stable.

[0099] Please see Figure 1 and Figure 7 The base 1 includes a first inclined wedge 12 and a second inclined wedge 13. A gap forming a dust collection port is formed between the first inclined wedge 12 and the second inclined wedge 13. The top surface of the first inclined wedge 12 is a first inclined surface, which gradually slopes downwards from the side away from the dust collection port to the side closer to the dust collection port. The top surface of the second inclined wedge 13 is a second inclined surface, which also gradually slopes downwards from the side away from the dust collection port to the side closer to the dust collection port. The cutting device for the sheet metal also includes a dust collection drawer 5, which is movably connected to the bottom of the base 1 along a first direction D1 and located between the first inclined wedge 12 and the second inclined wedge 13. The dust collection drawer 5 has a dust collection groove 51, and the top of the dust collection groove 51 has an opening communicating with the dust collection port. In this embodiment, the first and second inclined surfaces are arranged in a V-shape.

[0100] The negative pressure air source can absorb most of the dust through the dust collection port 4111. A small amount of dust slides down from the first and second inclined surfaces through the dust drop ports to the dust collection drawer 5 for collection and treatment, enabling rapid cleaning, improving dust removal efficiency, and reducing the impact of fiberglass dust on the working environment and the threat to the health of operators. The negative pressure air source can be an industrial vacuum cleaner.

[0101] Both the dust inlet and the dust collection drawer 5 extend along the first direction D1. The base 1 includes a first support frame 14 and a second support frame 15 disposed opposite each other along the first direction D1. The second support frame 15 is movable along the first direction D1, and the outline of the bottom of the second support frame 15 is adapted to the first inclined surface and the second inclined surface, and the bottom of the second support frame 15 contacts the first inclined surface and the second inclined surface. The clamping assembly 3 includes a first clamping assembly 31 and a second clamping assembly 32. The first clamping assembly 31 is disposed on the first support frame 14 and is used to clamp the plate onto the first support frame 14. The second clamping assembly 32 is disposed on the second support frame 15 and is used to clamp the plate onto the second support frame 15.

[0102] By moving the second support frame 15 along the first direction D1, the second support frame 15 can be used as a scraper to scrape the dust on the first and second inclined surfaces down to the dust collection port and be collected by the dust collection drawer 5, further improving the dust removal effect. The first pressing component 31 and the second pressing component 32, which are arranged in two rows at intervals, can press the plate more stably.

[0103] The base 1 also includes a second lead screw 16, a second operating handle 17, and a second nut 18. The second lead screw 16 extends along a first direction D1, and its two ends are respectively connected to the two sides of the base 1 located in the first direction D1. The second lead screw 16 is threadedly connected to the second support frame 15. The second operating handle 17 is connected to one end of the second lead screw 16, allowing for easy rotation of the second lead screw 16, thereby driving the second support frame 15 to move along the first direction D1. The second nut 18 is threadedly connected to the second lead screw 16. After rotating the second lead screw 16 to drive the second support frame 15 into position, the second lead screw 16 can be locked by rotating the second nut 18 against the base 1.

[0104] It is worth mentioning that the V-shaped arrangement of the first and second inclined surfaces can restrict the rotation of the second support frame 15, so that the rotation of the second lead screw 16 can be converted into the travel of the second support frame 15.

[0105] Please see Figure 7 and Figure 8 and combined Figure 1 The first pressing assembly 31 includes a first pressing plate 311 and a first pressing member 312. The first pressing plate 311 is disposed above the first support frame 14, and two first pressing members 312 are respectively disposed at both ends of the first pressing plate 311. The first pressing members 312 drive the first pressing plate 311 to move up and down. The second pressing assembly 32 includes multiple sets of second pressing plates 321 and second pressing members 322 arranged at intervals along the second direction D2. The second pressing plates 321 are disposed above the second support frame 15, and the second pressing members 322 drive the second pressing plates 321 to move up and down.

[0106] The length of the first clamping plate 311 is greater than the length of the second clamping plate 321. Multiple second clamping plates 321 clamp the plate at multiple points, providing a more secure fixation and preventing displacement during cutting. Furthermore, considering the uneven thickness of larger plates, the multiple second clamping plates 321 can solve the problem of insecure clamping due to uneven thickness. Therefore, this cutting device is suitable for large-sized plates.

[0107] When clamping the sheet material, the sheet material can pass through the gap between the first support frames 14 of the first clamping plate 311 until the end of the sheet material moves between the second clamping plate 321 and the second support frame 15. The first clamping plate 311 and the second clamping plate 321 are lowered to clamp the sheet material. Excess portion of the sheet material can protrude from the outside of the first clamping plate 311 facing away from the second clamping plate 321, so the clamping assembly 3 can be used to clamp sheets of different specifications.

[0108] The top of the first support frame 14 has a T-shaped groove 151 at each end of the first pressing plate 311. The top of the second support frame 15 has multiple T-shaped grooves 151. Both the first pressing plate 311 and the second pressing plate 321 have T-shaped sliding parts 3211, which are movably disposed within the grooves 151. The cooperation between the grooves 151 and the sliding parts 3211 restricts the rotation of the first pressing plate 311 and the second pressing plate 321. Both the first pressing member 312 and the second pressing member 322 include a third lead screw 3221 and a third nut 3222. The third lead screw 3221 of the first clamping member 312 is threadedly connected to the first clamping plate 311 and the first support frame 14. The third lead screw 3221 of the second clamping member 322 is threadedly connected to the second clamping plate 321 and the second support frame 15. Rotating the third lead screw 3221 can drive the first clamping plate 311 and the second clamping plate 321 to rise and fall. The third nut 3222 is threadedly connected to the third lead screw 3221. After rotating the third lead screw 3221 drives the first clamping plate 311 and the second clamping plate 321 to rise and fall to the correct position, the third lead screw 3221 can be locked by rotating the third nut 3222 to press against the first clamping plate 311 or the second clamping plate 321.

[0109] Understandably, the direction of the cutting component 4 and the clamping component 3 can be adjusted in both the horizontal and vertical directions as needed, enabling the cutting device to cut different types of plate samples.

[0110] Please see Figures 7 to 9 and combined Figure 1The cutting device for sheet metal also includes a limiting member 6. The limiting member 6 includes a limiting baffle 61 and a limiting rod 62. Both the limiting baffle 61 and the limiting rod 62 are hinged to the side of the base 1, and the rotation axis of the limiting baffle 61 and the rotation axis of the limiting rod 62 are perpendicular to each other. When the limiting baffle 61 rotates downwards, the downward rotation of the limiting rod 62 can prevent the limiting baffle 61 from rotating upwards. When the limiting rod 62 rotates upwards, it can allow the limiting baffle 61 to rotate upwards or downwards.

[0111] When in use, the cutting device for sheet metal can be placed entirely on a tabletop, with the base 1 supported above the table. By rotating the limiting baffle 61 downwards and causing the limiting rod 62 to rotate downwards to prevent the limiting baffle 61 from rotating upwards, the limiting baffle 61 is pressed against the side of the tabletop, thus restricting the cutting device from shifting. Multiple limiting members 6 can be provided as needed. In this embodiment, two limiting members 6 are provided, respectively located at two opposite corners of the base 1. One limiting member 6 restricts the cutting device from shifting in the first direction D1, and the other limiting member 6 restricts the cutting device from shifting in the second direction D2.

[0112] The base 1 is also provided with a connected receiving groove 191 and a positioning groove 192. The limiting baffle 61 includes a plate body 611 and a positioning block 612 connected to each other. When the limiting baffle 61 rotates upward, the plate body 611 enters the receiving groove 191 and the positioning block 612 enters the positioning groove 192. By rotating the limiting rod 62 upward, the limiting rod 62 is blocked outside the positioning block 612, which can prevent the limiting baffle 61 from rotating downward.

[0113] Although the invention has been described with reference to several typical embodiments, it should be understood that the terminology used is illustrative and exemplary, and not restrictive. Since the invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
