Description

Technical Field

[0001] The present invention relates to the technical field of cutting of marine outfitting parts, in particular to a cutting device for marine outfitting parts. Background Art

[0002] Marine outfitting is a general term for all parts, devices and facilities in the shipbuilding process except for the hull structure and electromechanical equipment. They are of many types and have different functions, covering all areas and systems of the ship. There are many types of marine outfitting, which are mainly assembled from plates and pipes. Therefore, before processing marine outfitting, the plates and pipes need to be cut to facilitate welding and assembly. There are many types of pipes, and here we mainly cut triangular pipes.

[0003] The traditional cutting method is to clamp and fix multiple triangular pipe fittings before cutting. Existing cutting machines are generally only used to fix and cut triangular pipe fittings with special angles such as equilateral triangles or isosceles right triangles in cross-section. However, in the actual processing of marine outfitting parts, in order to save costs and meet special functions, its components include triangular pipe fittings with non-equilateral triangle cross-sections. Therefore, existing cutting machines cannot cut triangular pipe fittings with non-equilateral triangle cross-sections. The cutting object is single, resulting in limitations in its cutting object. Non-equilateral triangles have many angle compositions. If they need to be cut, another cutting machine needs to be designed, which increases the cost of processing marine outfitting parts.

[0033] See Figure 2 The adjusting frame 15 has multiple sets of thread groups evenly arranged along its linear direction, and the thread groups are composed of left-right symmetrical thread grooves.

[0034] See Figure 2 、 Figure 3 、 Figure 4 and Figure 5 The resisting frame 16 includes a resisting plate 161. Resisting plates 161 are symmetrically arranged on the rectangular plate 121 and on the left and right sides of the triangular groove 122. The upper end of the resisting plate 161 is an arcuate surface. The lower ends of the two symmetrically arranged resisting plates 161 are hinged together through a positioning rod 1. A torsion spring is evenly sleeved on the positioning rod 1. The two ends of the torsion spring are fixedly connected to the resisting plates 161 on the left and right sides respectively. Round head plates 162 are symmetrically connected to the left and right sides of the triangular groove 122 on the rectangular plate 121 for sliding left and right. The arc surface of the round head plate 162 is located at the upper part. The round head plate 162 contacts the corresponding upper part of the resisting plate 161, and the left and right symmetrical threaded grooves on the adjusting frame 15 are threadedly connected to the corresponding round head plates 162.

[0035] See Figure 2 、 Figure 3 、 Figure 4 and Figure 5The adjusting frame 17 includes a rotating rod 171, which is rotatably connected to the lower pressure plate 141. A plurality of threaded segments are evenly arranged on the rotating rod 171, and a trapezoidal plate 172 is threadedly connected to the threaded segments. The inclined surface of the trapezoidal plate 172 is located at the lower end, and the inclined surface is higher on the right and lower on the left. The trapezoidal plate 172 is slidably connected to the lower pressure plate 141 left and right.

[0036] See Figure 2 、 Figure 3 、 Figure 4 and Figure 5 The pressing piece frame 18 includes a pressing plate 181, and an anti-interference groove is opened at the lower end of the lower pressing plate 141. The lower side of the lower pressing plate 141 is evenly hinged with a pressing plate 181 through the second positioning rod along its linear direction from right to left, and the left and right ends of the pressing plate 181 are both arc-shaped surfaces. A torsion spring is symmetrically sleeved on the second positioning rod. One end of the torsion spring is fixedly connected to the lower pressing plate 141, and the other end of the torsion spring is fixedly connected to the pressing plate 181. A round head pressing plate 182 is slidably connected to the upper side of the lower pressing plate 141 and located on the left part of the pressing plate 181. The arc surface of the round head pressing plate 182 is located at the bottom, and the inclined surface of the trapezoidal plate 172 is slidably connected to the round head pressing plate 182 left and right. In the initial state, the pressing plate 181 is in a horizontal state.

[0037] When it is necessary to fix a triangular pipe fitting with an equilateral triangle cross section, multiple triangular pipe fittings are directly placed in the triangular groove 122, and then the threaded rods 132 on the front and rear sides are driven to rotate by an external motor, driving the lower pressure plate 141 to move down and press down the upper part of the triangular pipe fitting. When it is not completely compacted and positioned, the front end of the triangular pipe fitting is aligned by the external alignment device provided in front of the workbench 11, and the lower pressure plate 141 continues to press down, and the pressing plate 181 contacts the upper end face of the triangular pipe fitting with an equilateral triangle cross section. Since the upper end face of the triangular pipe fitting with an equilateral triangle cross section is horizontal, the pressing plate 181 is squeezed and is in a horizontal state, and the triangular pipe fitting is compacted and positioned. The triangular pipe fitting is driven forward by the external feeding machine provided at the rear of the workbench 11 as needed until the extended triangular pipe fitting reaches the cutting length, and the three The angular pipe fittings stop moving, and the cutting knife 24 is driven to rotate by an external motor, and then the fixed shell 23 is driven to move to the right by the distance control cylinder 22, thereby driving the cutting knife 24 to move to the right to cut all the triangular pipe fittings. After cutting, the threaded rods 132 on the front and rear sides are driven to rotate, so that the lower pressure plate 141 is moved up, and the upper part of the triangular pipe fittings is no longer fully compacted and positioned. At this time, the triangular pipe fittings are driven forward by the feeding machine set behind the workbench 11, and the cut triangular pipe fittings are pushed out of the cutting device, and then the threaded rods 132 on the front and rear sides are driven to rotate again by the external motor, driving the lower pressure plate 141 to move down, and pressing down the upper part of the triangular pipe fittings. When it is not fully compacted and positioned, the above operation is repeated until the extended triangular pipe fittings reach the cutting length again, and cutting is performed until the required number of triangular components are cut out.

[0038] See Figure 4 and Figure 6 When it is necessary to perform fixed cutting on triangular pipe fittings with cross sections of isosceles triangles, right triangles, and equilateral triangles, multiple triangular pipe fittings of the same type are still directly placed into the triangular groove 122. It should be noted that if the vertex angle of the isosceles triangle is greater than 60° and any inclination angle of the right triangle and the equilateral triangle is less than 60°, then when placing, the base angle or inclination angle with an angle less than 60° should be in contact with the corner of the triangular groove 122. At the same time, the inclined surface corresponding to the inclination angle or base angle needs to be lower on the left and higher on the right. Then, the external motor drives the adjustment frame 15 to rotate, driving the round head plate 162 to move toward each other, thereby driving the abutment plate 161 to rotate, so that the abutment plate 161 is tightly attached to the triangular pipe fitting. The threaded rods 132 on the front and rear sides are driven to rotate by an external motor, which drives the lower pressure plate 141 to move downward and press down the upper part of the triangular pipe fitting. At this time, the rotating rod 171 is driven to rotate by the external motor, which drives the trapezoidal plate 172 to move to the right, thereby driving the round head support plate 182 to move downward and the pressure plate 181 to rotate, so that the pressure plate 181 is in close contact with the upper surface of the triangular pipe fitting. The subsequent alignment and cutting steps are the same as those of the equilateral triangle.

[0039] See Figure 5 and Figure 7 When any inclination angle of the right triangle and the non-equilateral triangle is equal to 60°, the inclination angle equal to 60° is directly brought into contact with the angle of the triangular groove 122. At the same time, the inclined surface corresponding to the inclination angle needs to be lower on the left and higher on the right. The threaded rods 132 on the front and rear sides are driven to rotate by an external motor, driving the lower pressure plate 141 to move downward, and pressing down the upper part of the triangular pipe fitting. At this time, the rotating rod 171 is driven to rotate by an external motor, driving the trapezoidal plate 172 to move to the right, thereby driving the round head support plate 182 to move downward, driving the support plate 181 to rotate, so that the support plate 181 is in close contact with the upper surface of the triangular pipe fitting, and the subsequent alignment and cutting steps are the same as those of the equilateral triangle.

[0040] When it is necessary to perform fixed cutting on a triangular pipe fitting with an isosceles triangle cross section, multiple triangular pipe fittings are still directly placed in the triangular groove 122. It should be noted that if the vertex angle of the isosceles triangle is less than 60°, the vertex angle contacts the angle of the triangular groove 122 when placed. At this time, it is only necessary to drive the adjustment frame 15 to rotate through an external motor to drive the round head plate 162 to move toward each other, thereby driving the resistance plate 161 to rotate so that the resistance plate 161 is in close contact with the triangular pipe fitting. At this time, the threaded rods 132 on the front and rear sides are driven to rotate by an external motor respectively, and the lower pressure plate 141 is driven to move downward to press down the upper part of the triangular pipe fitting. The subsequent alignment and cutting steps are the same as those of the equilateral triangle.
