Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0017] A high-efficiency rebar cutting machine, reference Figures 1 to 9, including a first support seat 1 and a second support seat 2, the first support seat 1 and the second support seat 2 are arranged in parallel and spaced apart, a saw blade 7 is rotatably arranged on the second support seat 2, a plurality of connecting grooves 3 are arranged at corresponding positions on the first support seat 1 and the second support seat 2, the plurality of connecting grooves 3 of the first support seat 1 and the second support seat 2 are arranged in the radial direction of the same installation circle, and the installation circle is specifically the circle on which the saw blade 7 is located, a steel bar clamping mechanism 4 is arranged in each connecting groove 3 for clamping a steel bar, wherein the steel bar clamping mechanism 4 can slide in the connecting groove 3, the sliding direction is the radial direction of the installation circle, when the steel bar clamping mechanism 4 clamps the steel bar and slides, it can drive the steel bar to move close to or away from the saw blade 7, therefore the diameter of the saw blade 7 needs to be smaller than the inner diameter of the circle formed by the plurality of steel bars clamped by the steel bar clamping mechanism, that is, the saw blade 7 needs to be arranged inside the circle formed by the plurality of steel bars, and the saw blade 7 and the circle formed by the plurality of steel bars are coaxially arranged, so that when the plurality of steel bars move close to the saw blade 7, the saw blade 7 can simultaneously cut the plurality of steel bars.

[0018] The steel bar clamping mechanism 4 includes an upper roller part 41 and a lower roller part 42, the upper roller part 41 and the lower roller part 42 each include a roller support 43 and a supporting roller 44, the supporting roller 44 and the roller support 43 are rotatably connected, the roller support 43 is slidably connected with the first support seat 1 and the second support seat 2, and the sliding direction is the radial direction of the saw blade 7, the supporting rollers 44 of the upper roller part 41 and the lower roller part 42 are oppositely arranged and have a certain gap to form a clamping gap, the clamping gap is used to arrange the steel bar, and the clamping gaps of the steel bar clamping mechanisms 4 on the first support seat 1 and the second support seat 2 are coaxially arranged, so as to ensure the coaxiality of the steel bar during clamping, a supporting spring 45 is arranged between the upper roller part 41 and the lower roller part 42, the supporting spring 45 is fixedly connected with the two roller supports 43 respectively, and the upper roller part 41 and the lower roller part 42 are caused to move close to each other and clamp the steel bar by the action of the supporting spring 45.

[0019] It should be noted that the clamping effect of the steel bar clamping mechanism 4 depends on the stiffness coefficient and spring wire diameter of the supporting spring 45, and specific parameter selection is a conventional technical means in the art.

[0020] In addition, in the embodiment, a certain rotational damping is arranged between the supporting roller 44 and the roller support 43 to ensure that the steel bar does not move axially when moving close to or away from the saw blade 7, and to ensure the cutting accuracy, and the steel bar can move axially under the pushing of an external force.

[0021] In order to prevent the steel bar clamping mechanism 4 from deviating during sliding, a limiting block 46 is arranged on the connecting groove 3 along the radial direction of the installation circumference, a limiting groove 47 is arranged on the roller support 43, and the limiting block 46 is slidingly arranged in the limiting groove 47. When the steel bar clamping mechanism 4 slides, it slides along the direction of the limiting block 46, and the sliding is more stable.

[0022] The steel bar clamping mechanism 4 is connected with a pushing mechanism 5 for driving it to slide. Through the action of the pushing mechanism 5, the steel bar clamping mechanism 4 can clamp the steel bar to move close to or away from the saw blade 7. The pushing mechanism 5 includes a mounting hole 51 arranged in the connecting groove 3 of the first support base 1, a sliding groove 52 is opened on the side surface of the first support base 1, the sliding groove 52 is arranged along the radial direction of the installation circumference, the sliding groove 52 is communicated with one end of the mounting hole 51 away from the steel bar clamping mechanism 4, a connecting rod 53 is coaxially slidingly arranged in the mounting hole 51, one end of the connecting rod 53 is fixedly connected with the roller support 43 of the lower roller part 42, the other end is connected with a push rod 54, the push rod 54 is arranged in the sliding groove 52, a rotating disc 55 is rotatably connected on one side surface of the first support base 1 where the push rod 54 is located, the rotating disc 55 is provided with a number of inclined grooves 56 equal to that of the push rod 54, the push rod 54 is slidingly arranged in the inclined grooves 56, and the inclined grooves 56 are connected with a driving mechanism for driving the rotating disc 55 to rotate.

[0023] The driving mechanism includes an outer gear ring arranged on the outer edge of the rotating disc 55, the outer gear ring is engaged with a driving gear 57, the driving gear 57 is rotatably connected with the first support base 1, the driving gear 57 is drivingly connected with a first motor 58, and the first motor 58 is fixedly connected with the first support base 1. In the present embodiment, the first motor 58 is drivingly connected with the driving gear 57 through a gear set, and in other embodiments, other structures can also be used for driving.

[0024] When the first motor 58 rotates, the first motor 58 drives the driving gear 57 to rotate, the driving gear 57 drives the outer gear ring and the rotating disc 55 to rotate, and when the rotating disc 55 rotates, the push rod 54 moves and drives the connecting rod 53 to slide in the mounting hole 51 through the action of the inclined grooves 56 on the rotating disc 55, so as to pull the steel bar clamping mechanism 4 to drive the steel bar to move close to the saw blade 7, and then the steel bar is gradually cut by the saw blade 7 until it is cut off. The specific cutting speed can be controlled by the rotating speed of the first motor 58, and then the speed of the steel bar moving close to the saw blade 7 is controlled. When the steel bar is completely cut off, the first motor 58 is stopped first, and then the direction is adjusted to be opposite to that during cutting. When the rotating disc 55 rotates in the opposite direction, the push rod 54 and the connecting rod 53 move outward along the radial direction of the saw blade 7, and the steel bar clamping mechanism 4 drives the steel bar to move away from the saw blade 7, and then the next cutting step is started.

[0025] In order to reset the reinforcing bar clamping mechanism 4 more conveniently, a first spring 59 is sleeved on one end of the connecting rod 53 close to the lower roller part 42, one end of the first spring 59 is fixedly connected with the roller support 43 of the lower roller part 42, and the other end is fixedly connected with the first support base 1.

[0026] The reinforcing bar clamping mechanism 4 of the second support base 2 is connected with an elastic support 6, specifically, the elastic support 6 includes a connecting hole 61 arranged in the connecting groove 3 of the second support base 2, the connecting hole 61 is arranged along the sliding direction of the reinforcing bar clamping mechanism 4, a support rod 62 is arranged in the connecting hole 61, the support rod 62 is in sliding connection with the connecting hole 61, a second spring 63 is sleeved on the support rod 62, one end of the second spring 63 is fixedly connected with the roller support 43 of the lower roller part 42 in the second support base 2, and the other end is fixedly connected with the second support base 2.

[0027] When the reinforcing bar approaches the saw blade 7, the first spring 59 and the second spring 63 are contracted to absorb energy, when the reinforcing bar is completely cut off, the first spring 59 and the second spring 63 push the reinforcing bar clamping mechanism 4 to reset, wherein in the first support base 1, the rotation of the rotating disc 55 and the simultaneous action of the first spring 59 are needed to reset, and in the second support base 2, the second spring 63 is directly used to reset.

[0028] In the embodiment, the saw blade 7 is driven to rotate by the second motor 8, and the second motor 8 is fixedly connected with the second support base 2.

[0029] In order to ensure that the saw blade 7 is kept in a good temperature range during cutting, a water spraying pipe can be arranged around the saw blade 7, and a cooling liquid can be introduced into the water spraying pipe, so that the cooling liquid can be sprayed to the saw blade 7 to cool it when the saw blade 7 is cutting.

[0030] The working principle of the embodiment is as follows: Firstly, the reinforcing bars are manually or by using a device to pass through the reinforcing bar clamping mechanism 4 of the first support base 1 and the second support base 2, so that the reinforcing bars are distributed along the periphery of the saw blade 7 in a circumferential direction, then the first motor 58 and the second motor 8 are started, the first motor 58 drives the driving gear 57 to rotate, the driving gear 57 drives the outer gear ring and the rotating disc 55 to rotate, when the rotating disc 55 rotates, the push rod 54 is moved and drives the connecting rod 53 to slide in the mounting hole 51, so as to pull the reinforcing bar clamping mechanism 4 and drive the reinforcing bars to approach the saw blade 7, then the reinforcing bars are gradually cut by the saw blade 7 until they are cut off.

[0031] After cutting, the first motor 58 stops first, and then the steering is adjusted to be opposite to that during cutting. When the rotating disc 55 rotates reversely, the push rod 54 and the connecting rod 53 are pushed to move radially outward along the saw blade 7, and the reinforcing bar clamping mechanism 4 drives the reinforcing bar to move away from the saw blade 7. Then, the cut reinforcing bar section is manually taken off from the second support seat 2 for collection. The reinforcing bar is manually or by equipment pushed to move, and is inserted into the reinforcing bar clamping mechanism 4 of the second support seat 2. The position of the reinforcing bar is further adjusted according to the length to be cut, the cutting point is aligned with the saw blade 7, and the first motor 58 and the second motor 8 are started again to cut the reinforcing bar by the saw blade 7.

[0032] Those skilled in the art will easily understand that the above description is only the preferred embodiment of the present application, and is not used to limit the present application. Any modification, equivalent replacement and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
