Description

Technical Field

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

[0002] Marine outfitting parts are a general term for all components, devices and facilities except the hull structure and electromechanical equipment during the shipbuilding process. They are various in types and functions, covering all areas and systems of the ship. Marine outfitting parts are diverse in types and are mainly assembled from plate parts and pipe parts. Therefore, before processing marine outfitting parts, it is necessary to cut the plate parts and pipe parts to facilitate welding and assembly. There are many types of pipe parts, and here mainly the triangular pipe parts are cut.

[0003] The traditional cutting method is to clamp and fix multiple triangular pipe parts and then cut them. Existing cutting machines generally only fix and cut triangular pipe parts 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, the components thereof include triangular pipe parts with non-equilateral triangles in cross-section. Therefore, existing cutting machines cannot cut triangular pipe parts with non-equilateral triangles, and the cutting object is single, resulting in limitations in the cutting object. The angle compositions of non-equilateral triangles are numerous. If it is necessary to cut them, additional cutting machines need to be designed, resulting in an increase in the cost of processing marine outfitting parts. Summary of the Invention

[0031] Refer to Figure 2 , multiple groups of thread sets are linearly and evenly formed on the adjustment frame 15. Each thread set is composed of symmetric left and right thread grooves.

[0032] Refer to Figure 2 , Figure 3 , Figure 4 and Figure 5 , the abutting member frame 16 includes an abutting member plate 161. Abutting member plates 161 are symmetrically arranged on the rectangular plate 121 on both sides of the triangular groove 122. The upper end of the abutting member plate 161 is an arc surface. The lower ends of the two symmetrically arranged abutting member plates 161 are jointly hinged through a positioning rod one. A torsion spring is evenly sleeved on the positioning rod one. The two ends of the torsion spring are respectively fixedly connected to the left and right abutting member plates 161. Round head plates 162 are symmetrically slidably connected to the rectangular plate 121 on both sides of the triangular groove 122. The arc surface of the round head plate 162 is located at the upper part. The round head plate 162 is in contact with the upper part of the corresponding abutting member plate 161. The symmetric left and right thread grooves on the adjustment frame 15 are threadedly connected to the corresponding round head plates 162.

[0033] Refer to Figure 2 , Figure 3 , Figure 4 and Figure 5, the adjusting frame 17 includes a rotating rod 171. The rotating rod 171 is rotatably connected to the lower pressing plate 141. A plurality of threaded segments are evenly formed on the rotating rod 171. Trapezoidal plates 172 are threadedly connected to the threaded segments. The inclined surface of the trapezoidal plate 172 is located at the lower end, with the right side higher than the left side. The trapezoidal plate 172 is slidably connected to the lower pressing plate 141 in the left-right direction.

[0034] Refer to Figure 2 , Figure 3 , Figure 4 and Figure 5 , the pressing member frame 18 includes a pressing plate 181. An anti-interference groove is formed at the lower end of the lower pressing plate 141. The pressing plate 181 is hinged to the lower side of the lower pressing plate 141 from right to left along its linear direction through a second positioning rod. Both the left and right ends of the pressing plate 181 are arc-shaped surfaces. Torsion springs are symmetrically sleeved on the front and back of 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-headed pressing plate 182 is slidably connected to the upper side of the lower pressing plate 141 and located on the left side of the pressing plate 181. The arc-shaped surface of the round-headed pressing plate 182 is located at the lower part. The inclined surface of the trapezoidal plate 172 is slidably connected to the round-headed pressing plate 182. In the initial state, the pressing plate 181 is in a horizontal state.

[0035] When it is necessary to fix a triangular pipe fitting with an equilateral triangle cross-section, directly place multiple triangular pipe fittings into the triangular groove 122, and then drive the threaded rods 132 on the front and rear sides to rotate respectively through an external motor, drive the lower pressing plate 141 to move downward, and press down on the upper part of the triangular pipe fitting. When it is not completely compacted and positioned, align the front end of the triangular pipe fitting through an external alignment device arranged in front of the workbench 11. The lower pressing plate 141 continues to press down, and the pressing plate 181 contacts the upper end surface of the triangular pipe fitting with an equilateral triangle cross-section. Since the upper end surface of the triangular pipe fitting with an equilateral triangle cross-section is horizontal, the pressing plate 181 is in a horizontal state under extrusion and compacts and positions the triangular pipe fitting. According to needs, drive the triangular pipe fitting to move forward through an external feeding machine arranged behind the workbench 11 until the protruding triangular pipe fitting reaches the cutting length. The triangular pipe fitting stops moving. Drive the cutting knife 24 to rotate through an external motor, and then drive the fixed shell 23 to move to the right through the distance control cylinder 22, thereby driving the cutting knife 24 to move to the right and cutting all the triangular pipe fittings. After cutting, drive the threaded rods 132 on the front and rear sides to rotate, make the lower pressing plate 141 move upward, and no longer completely compact and position the upper part of the triangular pipe fitting. At this time, drive the triangular pipe fitting to move forward through the feeding machine arranged behind the workbench 11, push out the cut triangular pipe fitting from the cutting device, and then drive the threaded rods 132 on the front and rear sides to rotate respectively through an external motor again, drive the lower pressing plate 141 to move downward, and press down on the upper part of the triangular pipe fitting. When it is not completely compacted and positioned, repeat the above operations until the protruding triangular pipe fitting reaches the cutting length again and perform cutting until the required number of triangular components are cut out.

[0036] Refer to Figure 4 With Figure 6 , when it is necessary to fix and cut triangular pipe fittings with an isosceles triangle, right triangle, and non-equilateral triangle cross-section, still directly place multiple triangular pipe fittings of the same type into the triangular groove 122. It should be noted that if the apex angle of the isosceles triangle is greater than 60° and any inclination angle of the right triangle and non-equilateral triangle is less than 60°, then when placing, make the base angle or inclination angle less than 60° contact the angle of the triangular groove 122, and at the same time, the corresponding inclined surface of the inclination angle or base angle needs to be lower on the left and higher on the right. Then drive the adjustment frame 15 to rotate through an external motor, drive the round head plates 162 to move towards each other, thereby driving the pressing member plate 161 to rotate and making the pressing member plate 161 close to the triangular pipe fitting. Drive the threaded rods 132 on the front and rear sides to rotate respectively through an external motor, drive the lower pressing plate 141 to move downward, and press down on the upper part of the triangular pipe fitting. At this time, drive the rotating rod 171 to rotate through an external motor, drive the trapezoidal plate 172 to move to the right, thereby driving the round head pressing plate 182 to move downward, driving the pressing plate 181 to rotate, and making the pressing plate 181 close to the upper surface of the triangular pipe fitting. The subsequent alignment and cutting steps are the same as those for the equilateral triangle.

[0037] Refer to 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 external motor drives the threaded rods 132 on the front and rear sides to rotate respectively, driving the lower pressing plate 141 to move downward to press the upper part of the triangular pipe fitting. At this time, the external motor drives the rotating rod 171 to rotate, driving the trapezoidal plate 172 to move to the right, thereby driving the round head pressing plate 182 to move downward, driving the pressing plate 181 to rotate, so that the pressing plate 181 is closely attached to the upper surface of the triangular pipe fitting. The subsequent alignment and cutting steps are the same as those of the equilateral triangle.

[0038] When it is necessary to fixedly cut a triangular pipe fitting with an isosceles triangle cross-section, multiple triangular pipe fittings are still directly placed into the triangular groove 122. It should be noted that if the apex angle of the isosceles triangle is less than 60°, when placing, the apex angle is brought into contact with the angle of the triangular groove 122. At this time, only the external motor needs to be driven to drive the adjusting frame 15 to rotate, driving the round head plates 162 to move towards each other, thereby driving the pressing parts plate 161 to rotate, so that the pressing parts plate 161 is closely attached to the triangular pipe fitting. At this time, the external motor drives the threaded rods 132 on the front and rear sides to rotate respectively, driving the lower pressing plate 141 to move downward to press the upper part of the triangular pipe fitting. The subsequent alignment and cutting steps are the same as those of the equilateral triangle.
