Description

Technical Field

[0001] The present invention relates to the technical field of sheet metal cutting, and more specifically, to a cutting method, system, equipment and storage medium for sheet metal right-angle triangle components. Background Art

[0002] A large number of right-angled triangular components are required in shipbuilding. In traditional cutting technology, sheet metal cutting usually adopts sealed cutting along the contour of individual components. Since sealed cutting is cutting of individual components, a certain distance of uncut plates will be left between adjacent components during material arrangement. Therefore, the cutting process requires multiple arc starts and the cutting path needs to be adjusted to complete the whole plate cutting task, resulting in low productivity and material waste.

[0003] At present, most CNC cutting process schemes optimize the cutting path according to the Euler loop, minimize the number of arcing times, and shorten the idle travel distance of the cutting gun moving between the component contours. Therefore, a new continuous cutting method is urgently needed to improve cutting efficiency and reduce material loss. Summary of the invention

One purpose of the present invention is to provide a method for cutting sheet metal right-angle triangle components which can improve cutting efficiency and reduce material loss.

[0055] The present invention will be further described below with reference to the specific embodiments in the accompanying drawings.

[0056] See also Figure 1 to Figure 4 A method for cutting a sheet metal right-angle triangle component comprises the following steps:

[0057] Step 1. Use the hypotenuses of two right-angled triangle components 1 as common sides to form a first virtual rectangle 2;

[0058] Step 2. Determine the cutting mode according to the height of the first virtual rectangle 2 and the height of the raw steel plate;

[0059] When the height of the raw steel plate only meets the height of a single row of first virtual rectangles 2, a single row cutting mode is adopted, in which the first virtual rectangles 2 are sequentially arranged behind the raw steel plate for cutting;

[0060] When the height of the raw steel plate only meets the height of two rows of the first virtual rectangles 2, a double-row cutting mode is adopted. In the double-row cutting mode, the first virtual rectangle 2 is first mirrored upward to obtain a second virtual rectangle 3, and the first virtual rectangle 2 and the second virtual rectangle 3 form a third virtual rectangle 4. The third virtual rectangle 4 is then sequentially connected and arranged behind the raw steel plate for cutting;

[0061] When the height of the raw steel plate only meets the height of multiple rows of the first virtual rectangle 2; if the height of the raw steel plate meets the even multiple of the height of the first virtual rectangle 2, the double-row cutting mode is adopted for all; if the height of the raw steel plate meets the odd multiple of the height of the first virtual rectangle 2, the double-row cutting mode is adopted first, until the remaining height of the raw steel plate only meets the height of a single row of the first virtual rectangle 2, the single-row cutting mode is adopted;

[0062] Step 3. Setting the cutting path of the single-line cutting mode and the cutting path of the double-line cutting mode according to the principle of shortening the total cutting length;

[0063] Step 4. Move the cutting gun head of the cutting machine from the origin to the point of the cutting path;

[0064] Step 5. Run the arc cutting, and the cutting gun head moves along the cutting path to cut;

[0065] Step 6. After cutting, the cutting gun head turns off and returns to the origin.

[0066] In the single-row cutting mode, the first process square 5 is disposed at the lower end of the common side of the first virtual rectangle 2, and the second process square 6 is disposed at the upper end of the common side of the first virtual rectangle 2. The diagonal lines of the first process square 5 and the second process square 6 are both in the same straight line as the common side of the first virtual rectangle 2. The side lengths of the first process square 5 and the second process square 6 are used as chamfers for the hypotenuse of the right-angled triangle component 1, which can prevent the hypotenuse from being too sharp and prevent the hypotenuse from collapsing, thereby improving the cutting quality.

[0067] Mark the bottom edge of the i-th first process square 5 as a(2*i-1) and a(2*i); mark the top edge of the i-th first process square 5 as b(2*i-1) and b(2*i); mark the end point of the bottom edge of the last first virtual rectangle 2 as a(2*n+1), 1≤i≤n, and n is the number of first virtual rectangles 2.

[0068] Mark the bottom edge of the i-th second process square 6 as c(2*i-1) and c(2*i); mark the starting point of the top edge of the first virtual rectangle 2 as d1, and mark the top edge of the i-th second process square 6 as d(2*i) and d(2*i+1).

[0069] When n = 1, such as Figure 2 As shown, the cutting path is: a1→b2→a2→a3→b3→c2→c1→b2→b1→d1→d2→c1.

[0070] When n>1, the cutting path consists of three sections: in the first section, i increases from 2 to n, a1→b2→a2→a(2*i-1)→b(2*i-1)→b(2*i)→a(2*i)→···→a(2*n+1); in the second section, i decreases from n to 1, a(2*n+1)→c(2*i)→c(2*i-1)→b(2*i)→b(2*i-1)

[0071] →···→d1; in the third path, i increases from 1 to n-1, d1→d(2*i)→c(2*i-1)→c(2*i)→d(2*i+1)→···→d(2*n)→c(2*n-1).

[0072] Of course, the entire raw steel plate can be cut multiple times in a single-row cutting mode.

[0073] In the double-row cutting mode, a third process square 7 is arranged at the lower end of the common side of the second virtual rectangle 3, and a fourth process square 8 is arranged at the upper end of the common side of the second virtual rectangle 3. The diagonals of the third process square 7 and the fourth process square 8 are both in the same straight line with the common side of the second virtual rectangle 3.

[0074] The top edge of the second process square 6 coincides with the bottom edge of the third process square 7 .

[0075] The top edge of the i-th third process square 7 is marked as e(2*i-1) and e(2*i); the bottom edge of the i-th fourth process square 8 is marked as f(2*i-1) and f(2*i); the top edge of the i-th fourth process square 8 is marked as g(2*i-1) and g(2*i); and the end point of the top edge of the last second virtual rectangle 3 is marked as g(2*n+1).

[0076] A first transition point d0 is provided outside the point d1, and a second transition point f0 is provided outside the point f1.

[0077] When the number of the third virtual rectangles 4 = 2, as Figure 4 As shown, the cutting path is: a1→b2→a2→a3→b3→b4→a4→a5→c4→c3→b4→b3→c2→c1→b2→b1→d1→d2→c1→c2→d3→d4→c3→e3→f4→f3→d3→d2→e1→e2→e1→f2→f1→d1→d0→f0→f2→g2→g3→f3→f4→g4→g5→e4.

[0078] When the number of the third virtual rectangles 4 is greater than 2, the cutting path includes five sections: in the first section, i increases from 2 to n, a1→b2→a2→a(2*i-1)→b(2*i-1)→b(2*i)→a(2*i)→···→a(2*n+1); in the second section, i decreases from n to 1, a(2*n+1)→c(2*i)→c(2*i-1)→b(2*i)→b( 2*i-1)→···→d1; in the third path, i increases from 1 to n-1, d1→d(2*i)→c(2*i-1)→c(2*i)→d(2*i+1)→···→d(2*n); in the fourth path, i decreases from n to 2, d(2*n)→c(2*i-1)→e(2*i-1)→f(2*i)→f(2*i-1)→d(2*i-1)→

[0079] e(2*(i-1)-1)→e(2*(i-1))→e(2*(i-1)-1)→f(2*(i-1))→

[0080] f(2*(i-1)-1)···→d1→d0→f0; in the fifth path, i increases from 1 to n, f0→f(2*i-1)→f(2*i)→g(2*i)→g(2*i+1)···→e(2*n).

[0081] Of course, the two third virtual rectangles 4 can also be used as basic cutting units. After the entire raw steel plate is divided into multiple basic cutting units, only one basic cutting unit is cut each time, and then the next basic cutting unit is cut until the entire raw steel plate is cut.

[0082] Path a1→b2 is for cutting leads, path d1→d0→f0→f1 is for cutting transition leads, the distance between point d1 and the first transition point d0, and the distance between point f1 and the second transition point f0 are both greater than the radius of the cutting gun head, which can be set according to actual process requirements. The first process square 5, the second process square 6, the third process square 7, and the fourth process square 8 are of the same size, and the side length of the first process square 5 is greater than the radius of the cutting gun head, which can be set according to actual process requirements, so that the root angle is cut using a small spacing cutting method in the cutting path.
