Description

Technical Field

[0001] This application relates to the technical field of metal steel cutting, and particularly to a steel bar cutting machine. Background Art

[0002] For the cutting of metal steel, it is often necessary to cut steel bars of different thicknesses according to industrial processing requirements. A cutting machine is a device that cuts columnar metal bars into sheets or segments to facilitate further processing of the metal bars.

[0003] The current cutting machines include a frame, a feeding guide rail installed on the frame, and a cutting assembly installed on the frame and located above the feeding guide rail. Among them, a conveying space for placing metal bars is formed on the feeding guide rail. During use, the metal bars are placed in the conveying space, and then the metal bars to be cut are conveyed to directly below the cutting assembly through the feeding guide rail, and the metal bars are radially cut by the cutting assembly, so that the columnar metal bars are cut into multiple metal sheets or metal segments. Since the size of the conveying space on the feeding guide rail is fixed, there are usually certain restrictions on the specifications of the steel during cutting, and it can only cut a certain fixed specification of steel. Different cutting devices are required to cooperate with steel of different diameters, increasing the equipment cost in production.

[0004] In view of the above related problems, the inventor proposes a steel bar cutting machine that can transport and cut steel bars of different diameters according to production requirements. Utility Model Content

[0005] In order to be able to cut steel bars of different diameters, this application provides a steel bar cutting machine.

[0006] The steel bar cutting machine provided by this application adopts the following technical solutions:

[0007] A steel bar cutting machine includes an operation table, a feeding assembly, and a cutting assembly. A hollow chamber is opened on the operation table. The feeding assembly is located inside the hollow chamber. The feeding assembly includes two sliding chambers, a material carrying device located on the sliding chambers, and a driving device for driving the two sliding chambers to move. A conveying space is formed between the two material carrying devices.

[0008] By adopting the above technical solutions, the feeding assembly is located inside the hollow chamber. The two sliding chambers of the feeding assembly are slidably connected inside the hollow chamber. Through the drive of the driving device, the two sliding chambers of the feeding assembly approach or move away from each other, so that the conveying space formed between the two material carrying devices expands or contracts to adapt to the transportation requirements of steel bars of different diameters.

[0009] Optionally, the driving device includes a threaded control shaft and a second motor for controlling the rotation of the threaded control shaft. The threaded control shaft is provided with external threads with opposite rotation directions at both ends. The two sliding box chambers are respectively located on the external threads in different directions on the threaded control shaft and are threadedly connected to the threaded control shaft.

[0010] By adopting the above technical solution, the two sliding box chambers are respectively located on the external threads with opposite rotation directions at both ends of the threaded control shaft and are threadedly connected to the threaded control shaft. When the second motor drives the threaded control shaft to rotate, the two sliding box chambers are relatively close to or away from each other along the axis of the threaded control shaft inside the hollow cavity.

[0011] Optionally, the driving device further includes a fixed shaft, which passes through the two sliding box chambers and has both ends fixed on the inner walls on opposite sides of the hollow chamber, and the axis of the fixed shaft is placed parallel to the axis of the threaded control shaft.

[0012] By adopting the above technical solution, the fixed shaft and the threaded control shaft are both arranged through the two sliding box chambers and placed axially parallel, so that the connection between the two sliding box chambers and the hollow chamber is more stable, and the relative movement of the two sliding box chambers in the hollow chamber is more stable.

[0013] Optionally, the material carrying device includes a driving wheel rotatably connected to the sliding box chamber, a driven wheel rotatably connected to the sliding box chamber, a first motor for driving the driving wheel to rotate, a first conveyor belt sleeved on the outside of the driving wheel and the driven wheel, and support seats evenly spaced on the outer wall of the first conveyor belt.

[0014] By adopting the above technical solution, the first motor drives the driving wheel to rotate, and under the connection action of the conveyor belt, the driven wheel is linked, and the support seat rotates along the conveyor belt along the transportation direction of the conveyor belt.

[0015] Optionally, slide plates are evenly and fixedly arranged side by side on the outer wall of the first conveyor belt, and the support seats are fixed on the slide plates at intervals.

[0016] By adopting the above technical solution, the slides are evenly arranged on the first conveyor belt and fixedly connected to the first conveyor belt, and the support seats are fixedly connected to the slides, thereby enhancing the stability of the steel rods supported by the support seats on both sides of the first conveyor belts, and avoiding the support seats tilting away from the first conveyor belt due to force only on the upper side.

[0017] Optionally, the upper side of the support seat is arc-shaped, and the arc surface of the support seat is located on the side away from the first conveyor belt.

[0018] By adopting the above technical solution, the design of the arc surface of the support seat allows the gravity of the steel rod to be applied to the support seat in multiple directions, and the arc design can match the shape of the steel rod to just clamp the steel rod.

[0019] Optionally, box chute grooves are provided on the front and rear inner walls of the hollow chamber that face each other. The length direction of the box chute grooves is consistent with the sliding direction of the sliding box chamber. Sliders are provided at opposite ends of the sliding box chamber.

[0020] By adopting the above technical solution, through the chute grooves and the sliders, the two sliding box chambers are slidably connected to the inner wall of the hollow chamber, making the movement of the two sliding box chambers inside the hollow chamber smoother.

[0021] Optionally, the steel bar cutting machine further includes a conveying device. The conveying device is provided on the side of the cutting assembly away from the feeding assembly. The conveying device includes a placing table, a conveying component connected to the placing table, and a limiting component for sending the material cut by the cutting assembly to the conveying component.

[0022] By adopting the above technical solution, the conveying device can convey the material cut by the cutting assembly to the next technological process, avoiding the scattered distribution of the cut material.

[0023] Optionally, the conveying component includes a second conveyor belt installed on the placing table and a second motor for driving the second conveyor belt to convey. Two blocking plates are fixedly connected to the placing table, and the two blocking plates are respectively located on both sides of the second conveyor belt.

[0024] By adopting the above technical solution, the second motor drives the second conveyor belt to move. The setting of the blocking plates plays a limiting role, avoiding the scattering of the steel bars during the transmission by the second conveyor belt.

[0025] Optionally, the limiting component includes two limiting plates located between the cutting assembly and the two blocking plates.

[0026] By adopting the above technical solution, the limiting plates are located between the cutting assembly and the second conveyor belt, playing a limiting role on the material before the material cut by the cutting assembly enters the second conveyor belt, avoiding the scattered distribution of the just-cut material.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. Under the action of the thread control shaft, the two sliding box chambers approach or move away from each other relatively inside the hollow chamber, making the material carrying devices approach or move away from each other relatively, thereby changing the size of the conveying space to meet the transportation requirements for steel bars of different diameters and conveying the steel bars to the cutting assembly.

[0029] 2. The arc surface on the upper side of the support seat can better fit the steel bar being transported, enhancing the clamping stability of the two material carrying devices on the steel bar.

[0030] 3. The conveying device behind the cutting assembly enables the cut material to be continuously conveyed forward to the next process, avoiding the random scattering of the steel segments. Description of the Drawings

Detailed implementation manners

[0035] The following further elaborates on this application in conjunction with all the attached drawings.

[0036] This embodiment discloses a steel bar cutting machine. As Figure 1 shown, the steel bar cutting machine includes an operating table 1, a feeding assembly 2, a cutting assembly 3, and a conveying device 4. The operating table 1 is provided with a hollow chamber 11. The feeding assembly 2 is located inside the hollow chamber 11 of the operating table 1. The cutting assembly 3 is installed on the operating table 1 and is located on one side of the hollow chamber 11. The conveying device 4 is located on the side of the cutting assembly 3 away from the feeding assembly 2. During use, the metal steel bar is sent by the feeding assembly 2 to the cutting assembly 3 for cutting, and the cut material is conveyed by the conveying device 4 to the next process.

[0037] The feeding assembly 2 includes two sliding box chambers 21 slidably connected inside the hollow chamber 11, a material carrying device 22 installed on each sliding box chamber 21, and a driving device 23 for controlling the sliding of the two sliding box chambers 21 inside the hollow chamber 11. A conveying space for the steel bar to be inserted is formed between the two material carrying devices 22, and the conveying of the steel bar can be achieved through the two material carrying devices 22. Through the driving device 23, the two sliding box chambers 21 can be controlled to approach or move away from each other to adjust the distance between the two sliding box chambers 21 to meet the conveying requirements of steel bars of different sizes.

[0038] As Figure 2As shown in the figure, the material carrying device 22 includes a driving wheel 221 rotatably connected to the sliding box chamber 21, a driven wheel 222 rotatably connected to the sliding box chamber 21, a first conveyor belt 223 sleeved outside the driving wheel 221 and the driven wheel 222, and a first motor (not shown in the figure) for driving the driving wheel 221 to rotate. The first motor can be installed inside the sliding box chamber 21, and the output shaft of the first motor is connected to the driving wheel 221. By controlling the rotation of the driving wheel 221 with the first motor, the driven wheel 222 is driven to move in linkage under the action of the first conveyor belt 223, and the first conveyor belt 223 moves along the rotation direction of the driving wheel 221 and the driven wheel 222.

[0039] In order to better convey the steel bars, a plurality of support seats 225 are uniformly fixed on the outer wall of the first conveyor belt 223, and the plurality of support seats 225 are arranged at intervals along the direction of the first conveyor belt 223. The support seat 225 is in the shape of an inverted right trapezoid. The surface of the support seat 225 fixedly connected to the sliding plate 224 is perpendicular to the bottom surface of the support seat 225. The upper side of the support seat 225 is arc-shaped, and the arc surfaces on the upper side of the support seat 225 are all located on the side away from the first conveyor belt 223. Through the setting of the arc-shaped support seats 225, the steel bars can be lifted and limited by the support seats 225 on two material carrying devices 22 in the conveying space and smoothly conveyed to the cutting assembly 3.

[0040] In order to increase the support strength of the support seat 225 for the steel bars, a plurality of sliding plates 224 are fixedly connected side by side on the outer wall of the first conveyor belt 223, and the support seats 225 are fixedly connected to the sliding plates 224 at intervals.

[0041] The driving device 23 includes a second motor 233 fixedly connected to the outer wall of the operating table 1, a thread control shaft 232 fixedly connected to the conveying shaft of the second motor 233, and a fixed shaft 231 fixedly connected to the opposite inner walls of the hollow chamber 11. The thread control shaft 232 is horizontally placed, and the axes of the fixed shaft 231 and the thread control shaft 232 are parallel. The thread control shaft 232 passes through the two sliding box chambers 21, and external threads in opposite directions are provided at both ends thereof. The two sliding box chambers 21 are respectively located at both ends of the thread control shaft 232, and the thread control shaft 232 is threadedly connected to both sliding box chambers 21. The fixed shaft 231 passes through the two sliding box chambers 21 and is slidably connected to the two sliding box chambers 21. Driven by the second motor 233, the thread control shaft 232 rotates, driving the two sliding box chambers 21 to approach or move away from each other relatively, thereby realizing the adjustment of the size of the conveying space to meet the conveying requirements of steel bars of different sizes.

[0042] As Figure 1 and Figure 2As shown in the figure, in order to make the sliding of the sliding box chamber 21 in the hollow chamber 11 smoother, sliders 211 are fixedly connected to opposite ends of each sliding box chamber 21. Box chamber chutes 12 are provided on the inner walls of opposite ends of the hollow chamber 11, and the length direction of the box chamber chutes 12 is parallel to the axis of the threaded control shaft 232. When the second motor 233 drives the relative movement of the sliding box chamber 21, the sliders 211 of the two sliding box chambers 21 also move in the box chamber chutes 12.

[0043] As Figure 3 shown, in order to prevent the cut materials from scattering everywhere, the conveying device 4 can be installed on the cutting assembly 3 or connected to the operating table 1. In this application, the case where the conveying device 4 is connected to the operating table 1 is taken as an example for illustration. The conveying device 4 includes a placement table 41 connected to the operating table 1, a limiting component 42 for limiting the cut materials, and a conveying component 43 connected to the placement table 41 for conveying the cut materials.

[0044] The limiting component 42 includes two limiting plates 421 for restricting the movement of the materials everywhere, two connecting plates 422 for connecting the placement table 41 and the operating table 1, and two first nuts 423 and two second nuts 424 for connecting the placement table 41 and the operating table 1 through the connecting plates 422. One end of the placement table 41 abuts against the end of the operating table 1 away from the feeding assembly 2. The first nut 423 fixes one end of the connecting plate 422 on the side of the operating table 1 away from the feeding assembly 2, and the second nut 424 fixes the connecting plate 422 on the placement table 41. The two limiting plates 421 are fixed inside the two connecting plates 422 and perpendicular to the placement table 41.

[0045] The conveying component 43 includes a second conveyor belt 432 for transporting the materials, a third motor 433 for driving the second conveyor belt 432, and baffle plates 431 symmetrically arranged on both sides of the second conveyor belt 432, and the baffle plates 431 are perpendicular to the second conveyor belt 432. One end of the two limiting plates 421 abuts against the cutting assembly 3, and the other end extends in the conveying direction of the second conveyor belt 432, and the distance between the two limiting plates 421 gradually decreases from the end close to the cutting assembly 3 to the distance in the conveying direction of the second conveyor belt 432, and finally abuts against the baffle plates 431 on both sides of the second conveyor belt 432, so that the connected part between the cutting assembly 3 and the conveying device 4 forms a conveying space blocked by the limiting plates 421. The materials cut by the cutting assembly 3 reach the second conveyor belt 432 after passing through the limiting plates 421 and are transported to the next process by the second conveyor belt 432.

[0046] The implementation principle of this embodiment is:

[0047] When the steel bar cutting machine is working, according to the diameter of the steel bar to be transported as required, the first motor drives the threaded control shaft 232 to move, adjusts the distance of the conveying space between the two material carrying devices 22 so that the steel bar is just located on the support seat 225 of the material carrying device 22, and transports the steel bar to the cutting assembly 3 under the action of the first conveyor belt 223. The cut material passes through the limit plate 421 and is transported to the next process on the second conveyor belt 432.

[0048] The above are all preferred embodiments of this application, and the protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
