Description

Technical Field

[0001] The utility model relates to the technical field of steel bar bending equipment, in particular to a horizontal numerically controlled steel bar bending center. Background Art

[0002] A rebar bending machine is a device used to bend rebars, and is mainly used in the construction, bridge and tunnel industries. A rebar bending machine generally includes a clamping mechanism for clamping and fixing the rebars, a bending shaft that rotates around the clamping mechanism, and a driving mechanism that drives the bending shaft to rotate around the clamping mechanism. The process of rebar bending generally involves first fixing the rebar on a clamping mechanism, and then bending the rebar by rotating the bending shaft around the clamping mechanism.

[0003] The patent with announcement number CN215544580U discloses a steel bar feeding device and a CNC bending center, including a feeding platform for placing steel bars, and the steel bars can be placed on the feeding platform along the length direction of the feeding platform. A steel bar bending machine and a drop bin are arranged on one side of the feeding platform in sequence, and a hook plate is rotatably installed on one side of the steel bar bending machine.

DETAILED DESCRIPTION

[0020] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0021] The present application embodiment discloses a horizontal CNC steel bar bending center, referring to Figure 1 and Figure 2, including a feeding platform 1, a steel bar bending unit and a blanking bin. The steel bar bending unit and the blanking bin are arranged in sequence on one side of the feeding platform 1 along the width direction of the feeding platform 1. The steel bar bending unit includes a fixed steel bar bending machine 2 and a movable steel bar bending machine 3. The fixed steel bar bending machine 2 is fixedly installed on one side of the end of the feeding platform 1, and the movable steel bar bending machine 3 is slidably connected to one side of the feeding platform 1 along the length direction of the feeding platform 1.

[0022] The steel bar bending unit also includes a hook plate 4, which is provided on both the fixed steel bar bending machine 2 and the movable steel bar bending machine 3. One end of the hook plate 4 is rotatably connected to the fixed steel bar bending machine 2 / movable steel bar bending machine 3, and the other end extends to the upper feeding platform 1. The fixed steel bar bending machine 2 and the movable steel bar bending machine 3 are both hinged with a second driving cylinder, and the piston rod of the second driving cylinder is staggered and hinged with the hook plate 4 to drive the movable end of the hook plate 4 to rotate and rise upward. A first material receiving groove 41 is provided on the upper edge of the hook plate 4 extending to one end of the upper feeding platform 1. When the movable end of the hook plate 4 rotates and descends to the lowest position, the opening of the first material receiving groove 41 of the hook plate 4 is located below the edge of the feeding platform 1 close to the steel bar bending unit, and the staff can manually put the steel bars on the feeding platform 1 into the first material receiving groove 41. A discharge plate 42 is also provided on the fixed steel bar bending machine 2 and the movable steel bar bending machine 3. The top wall of the discharge plate 42 is inclined. The lower end of the top of the discharge plate 42 is connected to the steel bar bending mold cavity on the fixed steel bar bending machine 2 / the movable steel bar bending machine 3. When the movable end of the hook plate 4 rotates to the highest point, the inner bottom wall of the first receiving groove 41 is inclined toward the steel bar bending unit, and the upper end of the top of the discharge plate 42 is dislocated and extends into the first receiving groove 41. After the first receiving groove 41 in the hook plate 4 is filled with steel bars, the hook plate 4 repeats the up and down rotation process. The steel bars are intercepted by the discharge plate 42 that is dislocated and extends into the first receiving groove 41, and leave the first receiving groove 41, and slide into the steel bar bending mold cavity along with the discharge plate 42.

[0023] In the embodiment of the present application, a plurality of first conveying rollers 11 are arranged at intervals along the length direction of the loading platform 1. The first conveying rollers 11 are arranged horizontally along the width direction of the loading platform 1 and are rotatably connected to the loading platform 1. The staff can easily move the steel bars placed in the loading platform 1 along the length direction of the loading platform 1 through the first conveying rollers 11 on the loading platform 1.

A second receiving trough 51 is provided on the receiving rack 5. The second receiving trough 51 can be aligned with the first receiving trough 41 in the movable falling state of the hook plate 4. A plurality of second conveying rollers 52 are rotatably arranged in the second receiving trough 51. The rotation axis of the second conveying roller 52 is parallel to the rotation axis of the first conveying roller 11. The second conveying roller 52 flattens the entire inner bottom wall of the second receiving trough 51. The upper plane of the second conveying roller 52 is higher than the inner bottom wall of the first material receiving trough 41 when the movable end of the hook plate 4 is in the falling state. When the steel bars are pushed from the feeding platform 1 to the hook plate 4, the steel bars first fall into the second material receiving trough 51. The staff can easily drag the steel bars placed in the second material receiving trough 51 through the second conveying roller 52.

[0024] A first baffle 21 is also provided on the fixed rebar bender 2. The first baffle 21 is rotatably arranged on the fixed rebar bender 2 away from the edge of the movable rebar bender 3. The fixed rebar bender 2 is provided with a first driving member for driving the first baffle 21 to rotate. Specifically, the first driving member can be a first driving cylinder 22, which is hingedly connected to the fixed rebar bender 2. The first baffle 21 is rotatably arranged on the fixed rebar bender 2 via a rotating shaft. A crank is fixedly connected to the rotating shaft. The piston rod of the first driving cylinder 22 is hinged at one end of the crank away from the rotating shaft. When the first baffle 21 is rotated to be flat on the fixed rebar bender 2, the movable end of the first baffle 21 faces away from the movable rebar bender 3. The staff can pull the steel bars in the second receiving trough 51 out a certain length toward the first baffle 21, and after the steel bars are placed in the steel bar bending mold cavity, drive the first baffle 21 to rotate to vertical, and push the end of the steel bars to maintain abutment with the first baffle 21, thereby ensuring that the position of the steel bars is consistent during each bending process, thereby improving the quality of the steel bar products after bending.

[0025] Specifically, a second baffle 12 for abutting the end of the steel bar is provided at one end of the feeding platform 1 close to the fixed steel bar bending machine 2. The second baffle 12 is specifically staggered between the receiving frame 5 and the first baffle 21 to ensure that the steel bar falls into the second receiving trough 51.

[0026] Reference Figure 3A track 7 is fixedly installed on the ground at one side of the steel bar bending unit away from the loading platform 1 along the length direction of the loading platform 1.
