Technical Field

[0001] The utility model relates to the technical field of steel cable production, in particular to a steel cable unwinding, cutting and unloading machine. Background Art

[0002] In the past, steel strand products were sold in rolls. After delivery to the installation site, customers had to cut them manually, which was very inconvenient. Some customers also requested products in fixed lengths, such as 90 meters, 138.8 meters, and 150 meters. Based on customer needs and feedback, products were cut directly at the factory.

[0003] Conventional steel strand cutting is performed manually, where the strand is pulled from a coil to the desired length, then cut using a cutting machine to produce fixed-length sections. This cutting process requires manual pulling, is labor-intensive, and time-consuming. Furthermore, the strand drags on the ground, causing friction and wear that impacts product quality, making it impossible to meet the demands for high-efficiency, high-quality cutting. Summary of the Invention

[0004] In order to solve the problems that conventional steel strand cutting operations consume a lot of manpower and product quality is difficult to ensure, the utility model provides a steel cable unwinding, cutting and unloading machine, in which the steel strand is pulled by a traction device, the steel strand is cut by a cutting device, and the steel strand is carried and unloaded to a certain site by a flipping and unloading device, which can reduce the intensity of manual work and ensure product quality.

[0005] In order to achieve the above purpose, the technical solution adopted by the present utility model is:

[0006] The steel cable unwinding, cutting and unloading machine is used to cut steel strands to a fixed length. It includes a traction device, a cutting device and a flip unloading device arranged in a straight line at intervals.

[0007] The traction device includes a traction frame, a driven wheel and a driving wheel controlled by a traction motor. The driven wheel and the driving wheel are arranged on the traction frame to rotate up and down. The driven wheel and the driving wheel cooperate to clamp the steel strand up and down. The operation of the driving wheel and the driven wheel facilitates the traction and transportation of the steel strand.

[0008] The cutting device includes a cutting table and a cutting machine arranged above the cutting table, which is convenient for quickly cutting the steel strand;

[0009] The flip unloading device includes several flip unloading racks arranged in a straight line, each of the flip unloading racks includes a flip frame body and a flip angle iron controlled by a flip cylinder, the top edge of the flip frame body is hinged with the flip angle iron to facilitate the rotation of the flip angle iron and realize unloading, the flip angle irons in several flip unloading racks are connected in sequence to facilitate the movement of the steel strands between multiple flip angle irons.

[0010] Furthermore, the traction frame is a double-layer frame, the traction motor is arranged on the lower layer of the traction frame, the traction motor is a reduction motor, and the driving wheel is arranged on the output shaft of the traction motor to facilitate direct driving of the driving wheel.

[0011] Furthermore, a lifting cylinder is provided on the upper layer of the traction frame, and the lifting cylinder is arranged vertically. The piston rod of the lifting cylinder is connected downwardly to a lifting seat, which is convenient for controlling the up and down movement of the lifting seat. The driven wheel is rotatably provided on the lifting seat; guide columns are also vertically provided on both sides of the lifting seat, and the guide columns and the traction frame are slidably connected up and down, thereby improving the stability of the movement of the lifting seat.

[0012] Furthermore, guide angle irons are provided on both sides of the cutting table, and the guide angle irons on both sides are connected to each other. The cutting machine is arranged between the guide angle irons on both sides. The guide angle iron on one side is convenient for guiding the steel strand into the cutting machine, and the guide angle iron and the flip angle iron are connected to each other, and the guide angle iron on the other side is convenient for guiding the steel strand into the flip angle iron.

[0013] Furthermore, the cross-section of the flip frame is a right triangle, the surface where the hypotenuse of the flip frame is located is the blanking surface, and the steel strand is unloaded obliquely from top to bottom along the blanking surface. The flip angle iron for supporting the steel strand is arranged on the top of the blanking surface. The length of the flip angle iron is greater than the length of the flip frame, which facilitates the connection between two adjacent flip unloading frames. The flip cylinder is hinged between the flip angle iron and the flip frame to facilitate driving the flip angle iron to rotate.

[0014] Furthermore, a storage rack is provided at the bottom of the blanking surface to facilitate the temporary placement of the cut and fixed-length steel strands. The storage rack is arranged on one side of the bottom of the flip frame. The cross-section of the storage rack is in a "﹁" shape. A baffle is also provided on the storage rack. The baffle is arranged vertically to prevent the steel strands from falling from the storage rack.

DETAILED DESCRIPTION

[0027] The specific implementation of the present invention is described in detail below with reference to the accompanying drawings:

[0028] like Figures 1 to 6 As shown, the steel cable unwinding, cutting and unloading machine is used for cutting steel strands to a fixed length, and comprises a traction device 1, a cutting device 2 and a flip unloading device 3 arranged in a straight line. Figure 1 As shown, the coiled steel strand is pulled out by the pulling device 1, and the individual strands are arranged on the turning and unloading device 3 after passing through the cutting device 2. After being pulled out to a certain length, the strand is cut by the cutting device 2. After cutting, the turning and unloading device 3 unloads a fixed length of strand.

[0029] The traction device 1 includes a traction frame 101, a driven wheel 102, and a driving wheel 104 controlled by a traction motor 103. The traction frame 101 is a double-layer frame. The driven wheel 102 and the driving wheel 104 are both rubber wheels. The driven wheel 102 and the driving wheel 104 are arranged on the traction frame 101 to rotate up and down. The driven wheel 102 and the driving wheel 104 cooperate with each other to clamp the steel strand. After the driven wheel 102 and the driving wheel 104 are in operation, they can pull the steel strand and transport it to the workstations of the cutting device 2 and the flip unloading device 3. Figure 2 shown.

[0030] When the driving wheel 104 is installed, a traction motor 103 is set under the traction frame 101. The traction motor 103 is a reduction motor. The driving wheel 104 is set on the output shaft of the traction motor 103. The traction motor 103 can directly drive the driving wheel 104 to rotate.

[0031] During installation, the driven wheel 102 is mounted on the upper layer of the traction frame 101. A vertically arranged lifting cylinder 4 is attached to the upper layer of the traction frame 101. Its piston rod is connected downwardly to a lifting base 5, driving the base 5 up and down. To ensure stable movement, vertical guide posts 6 are mounted on either side of the base 5. These guide posts 6 are slidably connected to the traction frame 101. The driven wheel 102 is rotatably mounted on the base 5, allowing it to rise and fall, thereby varying the gripping force of the driven wheel 102 and the driving wheel 104 on the stranded wire.

[0032] The cutting device 2 includes a cutting table 21 and a cutting machine 22 arranged above the cutting table 21. Figure 3 As shown, the cutting machine 22 is a bench-type cutting machine 22 with a clamping mechanism 7. The cutting machine 22 uses the clamping mechanism 7 to clamp the steel strand to fix it and ensure the stability of the steel strand during cutting. The clamping mechanism 7 can adopt a bench vise structure and principle, but is not limited thereto.

[0033] The cutter 22 can be operated manually, i.e., manually pressing the cutter 22 to move the saw blade up and down, thereby achieving cutting. Alternatively, an automatic operation can be adopted, i.e., a cylinder is arranged between the cutting table 21 and the cutter 22, and the cylinder is used to move the saw blade up and down, thereby achieving automatic cutting. In this case, the clamping mechanism 7 also needs to be replaced with an automatic structure, for example, by using the cylinder to perform linear reciprocating movement to achieve automatic clamping and release of the steel strand.

[0034] Cutting device 2 serves as a receiving mechanism for the steel strands conveyed by traction device 1. After passing through cutting device 2, they enter turning and unloading device 3. To guide the steel strands during transport, guide angles 8 are positioned on either side of cutting table 21. These guide angles 8 are connected to each other, and a cutter 22 is positioned between them. The guide angles 8 on one side guide the steel strands into the operating range of cutter 22, while the guide angles 8 on the other side accurately guide the strands to a designated position within turning and unloading device 3.

[0035] The tilting unloading device 3 includes a plurality of tilting unloading racks 9 arranged in a straight line. The number of tilting unloading racks 9 is selected according to the length of the steel strand to be cut. If the required steel strand is long, a larger number of tilting unloading racks 9 can be selected and arranged in a straight line, so that multiple tilting unloading racks 9 can be used to support the fixed length of the steel strand.

[0036] Each overturning unloading rack 9 comprises an overturning rack body 91 and an overturning angle iron 93 controlled by an overturning cylinder 92. Figure 4 and Figure 5 As shown, the cross-section of the tilting frame 91 is an isosceles right triangle. A tilting angle iron 93 is hinged to the top edge of the tilting frame 91. Specifically, the hypotenuse of the tilting frame 91 forms the blanking surface 10. The cut steel strands are unloaded along the blanking surface 10 from top to bottom. The tilting angle iron 93 is located at the top of the blanking surface 10 to support the steel strands.

[0037] A turning cylinder 92 is hingedly connected between the turning angle iron 93 and the turning frame 91, and the turning cylinder 92 can drive the turning angle iron 93 to rotate. In a normal state, the turning angle iron 93 is in a "∨" shape, and the steel strand can be supported by the turning angle iron 93 inside the turning angle iron 93. The turning angle irons 93 in the turning unloading frames 9 are connected in sequence, that is, the length of the turning angle iron 93 is greater than the length of the turning frame 91, that is, the two ends of the turning angle iron 93 extend horizontally outward and extend beyond the length of the turning frame 91.

[0038] When arranging the flip unloading racks 9 according to the length of the steel strands, it is important to note the following: 1. The flip angle iron 93 of the first flip unloading rack 9, which is also the one closest to the cutting device 2, needs to be connected to the guide angle iron 8 on the side of the cutting table 21, and the end faces must fit together to ensure that the steel strands after passing through the cutting device 2 accurately enter the flip angle iron 93 of the flip unloading rack 9 to prevent the steel strands from hanging in the air. 2. When arranging two adjacent flip unloading racks 9, the flip angle irons 93 must also be connected to each other, and the end faces must fit together to ensure that the steel strands can pass through multiple flip unloading racks 9 smoothly and accurately.

[0039] The principle of the present invention is as follows: on the basis of the fixed positions of the traction device 1 and the cutting device 2, a corresponding number of flip unloading racks 9 are arranged according to the length of the steel strand to be cut, and the corresponding communication between the flip unloading racks 9 is ensured. During the cutting operation, the traction device 1 is started, and the driving wheel 104 and the driven wheel 102 cooperate to clamp the steel strand. The running driving wheel 104 and the driven wheel 102 cooperate to pull out the coiled steel strand, forcing the steel strand to pass through the cutting device 2 and flow into the flip angle iron 93. After pulling a certain length, the traction device 1 stops.

[0040] The cutting machine 22 is activated to cut the steel strand to a fixed length. Then, the tilting cylinders 92 on the multiple tilting unloading racks 9 are activated simultaneously, pushing the tilting angle irons 93 to rotate simultaneously, which is equivalent to flipping the fixed length of steel strand downward. The steel strand moves downward along the blanking surface 10 and falls to the ground. The tilting cylinders 92 are then reset, and the pulling device 1 continues to operate, continuing the pulling operation. After pulling a certain length, it stops and cuts again. This reciprocating process can complete the steel strand cutting operation.

[0041] Since the steel strands need to move in sequence between the multiple flip angle irons 93, in order to facilitate the smooth movement of the steel strands and reduce wear, multiple rolling assemblies 11 are spaced apart on each flip angle iron 93, such as Figure 6As shown. Each rolling assembly 11 includes side plates 111, bearings 112, and mounting shafts 113. Side plates 111 are provided on both sides of the tilting angle iron 93. The mounting shaft 113 extends between the two side plates 111. Bearings 112 are mounted on the mounting shafts 113 between the two side plates 111. Bearings 112 have holes corresponding to the positions of the tilting angle iron 93. Bearings 112 extend upward through the holes and out of the sidewalls of the tilting angle iron 93, allowing them to contact the steel strands. The rolling action of bearings 112 ensures smooth movement of the steel strands on the tilting angle iron 93.

[0042] In order to optimize the product structure and realize the temporary storage of the cut steel strands, a storage rack 12 is provided at the bottom of the blanking surface 10, that is, the storage rack 12 is arranged on one side of the bottom of the flip frame 91. In this way, the steel strands in the flip angle iron 93 can enter the storage rack 12 along the blanking surface 10. Figure 5 The cross-section of the storage rack 12 is in the shape of a "﹁". The horizontal section of the storage rack 12 can support the steel strands, and the vertical section of the storage rack 12 contacts the ground. The storage rack 12 is also provided with a barrier rod 13. The barrier rod 13 is arranged vertically and corresponds to the vertical section of the storage rack 12. The barrier rod 13 acts as a barrier to gather the steel strands on the storage rack 12 and prevent them from falling.

[0043] The embodiments described above are only preferred embodiments of the present invention and do not limit the scope of implementation of the present invention. Therefore, any equivalent changes or modifications made based on the structure, features and principles described in the patent scope of the present invention should be included in the scope of the patent application of the present invention.
