Description

Technical Field

[0001] This invention relates to the field of steel bar processing technology, specifically to a steel bar sawing machine and a method for handling overload during steel bar sawing. Background Technology

[0002] In the patent document with publication number "CN107511439A" and title "A Rebar Cutting Machine for Building Construction", a rebar cutting machine for building construction is disclosed. It includes a workbench, with support legs fixedly connected to the four corners of the bottom of the workbench. Support plates are fixedly connected to the inner sides of the support legs. A bracket is fixedly connected to the top of the workbench. A telescopic rod is fixedly connected to the top of the inner wall of the bracket. The cutting machine body is fixedly connected to the bottom of the telescopic rod. A placement plate is fixedly connected to the top of the support platform. The placement plate is located inside the bracket.

[0003] In the prior art and the comparison documents, the rebar cutter does not have an overload protection device. When the rebar cutter is overloaded, the saw blade will run slowly or stop moving. If this happens without intervention, the motor will burn out. In the prior art, when the sawing is overloaded, the sawing must be stopped and the rebar adjusted, such as by manually reducing the amount of rebar being cut, which is inconvenient to use.

[0004] Therefore, it is necessary to make improvements. Summary of the Invention

[0005] The purpose of this invention is to address the above-mentioned shortcomings by providing an overload-resistant rebar sawing machine and a method for handling overload during rebar sawing that can eliminate overload without stopping operation when it occurs, and is easy to operate.

[0006] The technical solution of the overload-resistant rebar sawing machine of the present invention is implemented as follows: The overload-resistant rebar sawing machine includes a frame, on which a clamp for holding the rebar to be sawed is installed. A column is also installed on the upper right side of the frame, and a sawing assembly connected to a lifting component is installed on the column. This lifting component is a sawing lifting component, and the sawing assembly includes a sawing motor and a saw blade driven by the sawing motor. The sawing lifting component and the sawing motor are connected to a control device. The key feature is that: a clamp base is provided below the clamp, and a rebar placement station for placing the rebar to be sawed is provided on the clamp base. A conical hole is provided below the rebar placement station on the clamp base, and a lifting component is connected to an upward-facing top cone in the conical hole. This lifting component is a top cone lifting component, and the top cone lifting component is connected to the control device. The top cone has an upward-facing tip.

[0007] Furthermore, the saw blade has a speed measuring instrument on its side, which is connected to a control device. When the speed measuring instrument detects that the speed of the saw blade is less than the set speed, the control device causes the top cone lifting component to rise.

[0008] Furthermore, there are multiple conical holes, which are arranged front to back or / and left to right at the placement station.

[0009] Furthermore, the clamp includes jaws on both sides, with the space between the two jaws being the placement position for sawing the reinforcing bars. These two jaws are the left jaw and the right jaw. The base has a horizontal slide rail, and the jaws are mounted on the slide rail. The jaws are connected to a jaw motor, which is connected to a control device. When the jaw motor operates, it drives the jaws to move on the slide rail, thereby changing the distance or position between the two jaws.

[0010] Furthermore, when the speed measuring instrument detects that the saw blade speed is less than the set speed, the control device causes the chuck motor to run.

[0011] Furthermore, the clamp is also mounted on the frame via a lifting device, which is a base lifting device. The base lifting device is connected to a control device. When the speed measuring instrument detects that the saw blade speed is less than the set speed, the control device causes the base lifting device to descend and then rise.

[0012] Furthermore, a vibration device is installed on the fixture. This vibration device is a fixture vibration device, and the vibration direction of the fixture vibration device is in the front-to-back direction.

[0013] Furthermore, a vibration device is installed on the sawing assembly. This vibration device is a sawing assembly vibration device, and the vibration direction of the sawing assembly vibration device is up and down.

[0014] The technical solution of the method for handling overload during steel bar sawing of the present invention is as follows: the method for handling overload during steel bar sawing is to eliminate the phenomenon of steel bar overload and steel bar clamping the saw blade by distributing multiple steel bars separately for sawing.

[0015] To elaborate further, when overloading or saw blade clamping occurs during rebar sawing, this issue can be resolved by changing the number or position of the multiple rebars being cut.

[0016] To elaborate further, if overloading or clamping of the saw blade occurs during the sawing of reinforcing bars, the reinforcing bars are first moved backward to move away from the saw blade, and then moved forward to contact the saw blade for cutting.

[0017] To elaborate further, it is used when the steel bar is overloaded or the saw blade is clamped during the sawing process, and the saw blade and the steel bar to be cut are cut by vibration.

[0018] The beneficial effects of this invention are: such an overload-proof rebar sawing machine and rebar sawing overload handling method have the advantages of eliminating overload without stopping operation when overload occurs and convenient operation. Attached Figure Description

[0024] The invention will now be further described with reference to the accompanying drawings.

[0025] like Figure 1 , 2As shown in Figures 3 and 4, an overload-resistant rebar sawing machine includes a frame 1, on which a clamp 2 for holding the rebar to be sawed is installed. A column 3 is also installed on the upper right side of the frame, and a sawing assembly 4 connected to a lifting component is installed on the column. This lifting component is a sawing lifting component 5. The sawing assembly includes a sawing motor 41 and a saw blade 42 driven by the sawing motor. The sawing lifting component and the sawing motor are connected to a control device 6. The machine is characterized by: a clamp base 21 below the clamp, a rebar placement station 22 on the clamp base for placing the rebar to be sawed, a conical hole 23 below the rebar placement station on the clamp base, and a lifting component connected to an upward-facing top cone 24 in the conical hole. This lifting component is a top cone lifting component 25, and the top cone lifting component is connected to the control device. The top cone has an upward-facing tip.

[0026] Working principle: When overload occurs during sawing of steel bars, which is when the saw blade has difficulty running, the operator can know this by observation. The operator can then activate the top cone lifting component, which raises the top cone and separates multiple steel bars that are together, reducing the amount of steel bars fed onto the saw blade and eliminating the overload phenomenon, thus achieving the purpose of this invention.

[0027] Furthermore, the saw blade has a speed measuring instrument 7 on its side, which is connected to a control device 6. When the speed measuring instrument detects that the speed of the saw blade is less than the set speed, the control device causes the top cone lifting component to rise.

[0028] In one embodiment, the speed measuring device 7 can be mounted on a protective cover on the side of the saw blade, and the speed measuring device is a component in the prior art.

[0029] This invention also has the advantage of higher automation, and the control device can be a PLC control device.

[0030] In one embodiment, there are multiple tapered holes 23, which are arranged front to back and / or side to side at the placement station. This arrangement also has the advantage of better separation of reinforcing bars.

[0031] Furthermore, the clamp 2 includes two jaws 26 on both sides, and the space between the two jaws is the placement position for sawing the steel bars. These two jaws are the left jaw and the right jaw. The clamp base 21 has a horizontal slide rail, and the jaws are installed on the slide rail 27. The jaws are connected to a jaw motor 28, and the jaw motor is connected to a control device. When the jaw motor runs, it drives the jaws to move on the slide rail, thereby changing the distance between the two jaws or changing the position between the two jaws.

[0032] This invention also allows for the adjustment of the number of steel bars to be cut. For example, when the two jaws move relative to each other, the steel bar placement station becomes narrower, reducing the number of steel bars to be cut per unit time and eliminating the overload phenomenon during steel bar cutting. Alternatively, when the two jaws move in the same direction, the steel bar placement station moves, allowing for adjustment of the object to be cut, thus also eliminating the overload phenomenon during steel bar cutting.

[0033] Furthermore, when the speed measuring instrument detects that the saw blade speed is less than the set speed, the control device causes the chuck motor 28 to run.

[0034] This invention also has the advantage of a higher degree of automation.

[0035] Furthermore, the clamp is also mounted on the frame via a lifting device, which is a base lifting device 8. The base lifting device is connected to a control device. When the speed measuring instrument detects that the saw blade speed is less than the set speed, the control device causes the base lifting device to descend and then rise.

[0036] The present invention is designed such that when overload occurs during the sawing of steel bars, the steel bars to be sawed are first lowered and sawing is temporarily suspended. The saw blade continues to run until it reaches a certain speed, at which point the steel bars are then sawed again, thus eliminating the overload phenomenon.

[0037] Furthermore, a vibration device is installed on the clamp 2. This vibration device is the clamp vibration device 9, and the vibration direction of the clamp vibration device is in the front-to-back direction.

[0038] This invention also enables the steel bar to vibrate in the front and back directions during sawing, eliminating overload on the sawing steel bar as it repeatedly contacts and detaches from the saw blade.

[0039] Furthermore, a vibration device is installed on the sawing assembly. This vibration device is the sawing assembly vibration device 10, and the vibration direction of the sawing assembly vibration device is up and down.

[0040] This invention also enables the saw blade to vibrate vertically during sawing, thus eliminating overload on the sawing of the steel bars as they repeatedly come into contact with and leave the saw blade.

[0041] The instruction manual is required because the above-mentioned overload-resistant rebar sawing machine can supplement the following methods for handling overload during rebar sawing. Readers can also use the overload-resistant rebar sawing machine and the examples to help them understand the methods for handling overload during rebar sawing.

[0042] The technical solution of the method for handling overload during steel bar sawing of the present invention is as follows: the method for handling overload during steel bar sawing is to eliminate the phenomenon of steel bar overload and steel bar clamping the saw blade by distributing multiple steel bars separately for sawing.

[0043] To elaborate further, when steel bar overload or saw blade clamping occurs during steel bar sawing, this problem can be eliminated by changing the number or position of the multiple steel bars being cut.

[0044] To elaborate further, if overloading or clamping of the saw blade occurs during the sawing of reinforcing bars, the reinforcing bars are first moved backward to move away from the saw blade, and then moved forward to contact the saw blade for cutting.

[0045] To elaborate further, it is used when the steel bar is overloaded or the saw blade is clamped during the sawing process, and the saw blade and the steel bar to be cut are cut by vibration.

[0046] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
