Description

Technical Field

[0001] This utility model relates to the field of steel coil packaging technology, and in particular to a dual-mode draw knife device. Background Technology

[0002] After processing, finished steel coils require further packaging to reduce defects such as oxidation and rust. Commonly used packaging materials are thin sheets such as checkered plates, approximately 0.2mm thick and 1.5m wide. Because these thin sheets are stored in rolls, they need to be cut to size according to the dimensions of the finished coil before use.

[0003] Cutting thin sheets commonly involves using electric shears or angle grinders, requiring workers to stand on the sheet to perform the cutting operation. Electric shears are inefficient, producing a large amount of metal shavings that are difficult to clean and pose a risk of injury to workers. Angle grinders generate significant sparks and dust, requiring the use of environmental protection equipment and making them unsuitable for applications that frequently require relocation.

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0025] Furthermore, reference numerals and / or reference letters may be repeated in different examples in this application. Such repetition is for simplification and clarity purposes and does not in itself indicate a relationship between the various embodiments and / or settings discussed. In addition, this application provides examples of various specific processes and materials; however, those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0026] Please refer to the reference. Figure 1 and Figure 2 This application discloses a dual-mode drawbar device, including a blade holder 100, a linear drive mechanism 200, and a handheld lever 300. The blade holder 100 includes a frame 110, with a first mounting position 111 and a second mounting position 112. The linear drive mechanism 200 is detachably connected to the frame 110 at the first mounting position 111, and the handheld lever 300 is detachably connected to the frame 110 at the second mounting position 112. The linear drive mechanism 200 drives the frame 110 to move linearly, and the handheld lever 300 is for manual use. This solution allows switching between automatic and manual modes. In use, the blade holder 100 is mounted on either the linear drive mechanism 200 or the handheld lever 300. The linear drive mechanism 200 drives the blade holder 100 to move linearly, or the handheld lever 300 is operated manually.

[0027] The blade holder 100 includes two shear blades 120, both of which are rotatably mounted on the frame 110. A cutting section 130 is formed between the two shear blades 120. When the plate to be cut is placed in the cutting section 130, the blade holder 100 moves along the plate to be cut, enabling the plate to be cut by the two shear blades 120.

[0028] This application solution can switch between automatic and manual modes. When in use, the blade holder 100 is mounted on the linear drive mechanism 200 or the hand lever 300. The linear drive mechanism 200 drives the blade holder 100 to move in a straight line, or the hand lever 300 is operated manually. Under the condition that the plate to be cut is placed in the cutting interval 130 between the two shear blades 120, the blade holder 100 moves along the width direction of the plate to be cut. When the blade holder 100 moves, the plate to be cut is quickly cut by the two shear blades 120.

[0029] The device of this application has the advantages of being flexible, lightweight and easy to operate. It can switch between manual and automatic modes. While ensuring work efficiency, the device of this application has a wider range of applications. Moreover, it does not generate iron filings, sparks and dust during cutting operations, which reduces the workload of operators, improves personal safety hazards, and does not require the use of environmental protection equipment, thus reducing environmental pressure.

[0030] Figure 2The cutting edge structure of the scissor blade 120 is not shown in the original drawing. In some embodiments, to accommodate the rotatable mounting of the scissor blade 120 to the frame 110, the scissor blade 120 has a rotating structure. The rotation center line of the rotating structure is the axis of the scissor blade 120. The scissor blade 120 has an axial direction 121 and a radial direction 122. The cutting edges of the scissor blade 120 are distributed on the circumferential surface of the rotating structure. Since the plate to be cut is a thin plate with a thickness of about 0.2 mm, the cutting edges of the two scissor blades 120 cannot be designed to face each other. In this application, the cutting edges of the two scissor blades 120 are staggered along the axial direction 121, and at least partially overlap along at least one radial direction 122. Figure 2 The image shows the axial direction 121 and radial direction 122 of the shear blade 120. Using the above scheme, when the blade holder 100 moves along the thin plate, the thin plate is automatically cut by the shear blade 120.

[0031] It should also be noted that the device of this application adopts a manual method of manually overlapping the thin plate in the cutting section 130, which can greatly simplify the device of this application.

[0032] In some implementation methods, please refer to Figure 2 The frame 110 includes a first plate 113, a second plate 114, and a third plate 115. The first plate 113, the second plate 114, and the third plate 115 are connected in sequence. The second plate 114 is distributed along the axial direction 121 of the shear blade 120, and the thickness direction of the second plate 114 is the radial direction 122 of the shear blade 120. The first plate 113 and the third plate 115 are connected to the opposite ends of the second plate 114 along the axial direction 121 of the shear blade 120. The first plate 113 and the third plate 115 are located on both sides of the thickness of the second plate 114. The first plate 113 and the third plate 115 are distributed along the radial direction 122 of the shear blade 120, and the thickness direction of the first plate 113 and the third plate 115 is the axial direction 121 of the shear blade 120. The two shear blades 120 are rotatably mounted on the first plate 113 and the third plate 115, respectively. The aforementioned frame 110 provides mounting for the two shear blades 120, enabling the installation purpose to be smoothly achieved in which the cutting edges of the two shear blades 120 are staggered in the axial direction 121 of the shear blades 120, and the cutting edges of the two shear blades 120 at least partially overlap in at least one radial direction 122 of the shear blades 120.

[0033] In some implementation methods, please refer to Figure 2 The frame 110 also includes a main body 116. One end of the third plate 115 away from the second plate 114 is connected to the main body 116. The first mounting position 111 is located on the main body 116. The main body 116 provides a mounting position for the linear drive mechanism 200.

[0034] In some embodiments, a second mounting position 112 is provided on a first plate 113, which provides a mounting position for the handgrip 300.

[0035] In some implementation methods, please refer to the reference. Figure 1 and Figure 2 The linear drive mechanism 200 includes a frame 210, a lead screw 220, a spacer 230, and a motor 240. The frame 210 has at least one guide rod 211, and the main body 116 is movably sleeved on the guide rod 211. The lead screw 220 is rotatably mounted on the frame 210, and the lead screw 220 is parallel to the guide rod 211. The first mounting position 111 is a first hole penetrating the main body 116, and the spacer 230 passes through the first hole and is detachably connected to the main body 116 by a bolt (spacer bolt 231 in the figure). Figure 2 As shown in the spacer bolt 231, the main body 116 and the spacer 230 are designed with mounting holes for assembling the spacer bolt 231, and the inner circumference of the spacer 230 is designed with threads to realize the threaded connection between the spacer 230 and the lead screw 220. The motor 240 is driven by the lead screw 220. When the motor 240 drives the lead screw 220 to rotate, under the premise that the guide rod 211 restricts the main body 116 from rotating, the spacer 230 moves along the length direction of the lead screw 220, and the spacer 230 moves together with the blade holder 100 along the length direction of the lead screw 220.

[0036] In more feasible implementations, the linear drive mechanism 200 can also be implemented using hydraulic cylinders, pneumatic cylinders, etc.

[0037] In some implementation methods, please refer to the reference. Figure 1 and Figure 2 The frame 210 is equipped with two guide rods 211, which are parallel to each other, and the lead screw 220 is arranged parallel between the two guide rods 211.

[0038] In some embodiments, the dimension of the frame 210 along the length of the guide rod 211 is not less than the width of the plate to be cut. For example, when the width of the thin plate is 1.5m, the dimension of the frame 210 along the length of the guide rod 211 is greater than or equal to 1.5m.

[0039] In some embodiments, the second mounting position 112 is a second hole opened in the first plate 113, and the hand handle 300 is bolted to the first plate 113 to achieve a detachable connection between the hand handle 300 and the first plate 113.

[0040] In some embodiments, the handheld lever 300 includes a main lever 310 and a handle 320 connected to one end of the main lever 310. The other end of the main lever 310 is detachably connected to the first plate 113. The handle 320 is bent at the connection with the main lever 310. This handheld lever 300 can also be called an L-shaped lever, which makes it easy for a person to hold it.
