[0001] The invention relates to the technical field of building material bending, in particular to a bending device for building material processing. Background Art

[0002] Building pipes refer to the materials used to transport fluids and carry solid wires in buildings. They are an indispensable part of construction projects, especially in mechanical and electrical installations and building piping systems.

[0003] Building pipe bending refers to the bending of metal pipes during construction or pipe processing to meet the specific requirements of building design or the direction of the pipe. Bending is usually used in various pipe systems, such as water supply and drainage systems, HVAC systems, fire protection systems, etc., to meet the layout and installation requirements of pipes inside buildings.

[0004] The existing patent (Announcement No.: CN118218448B) discloses a material bending device for construction, including a processing table assembly and a bending compensation mechanism, wherein the processing table assembly includes a processing table frame, an outer support frame and a bending turntable; wherein the outer support frame is fixedly connected to the middle of one side of the processing table frame, the bending turntable is rotatably connected to the upper surface of the processing table frame, and the bending compensation mechanism is installed on one side of the upper surface of the bending turntable.

[0005] In view of this, we propose a bending device for processing building materials. Summary of the invention

[0006] The purpose of the present invention is to provide a bending device for processing building materials, so as to solve the problem in the above background technology that the running track of the pressing wheel used for bending steel pipes in the prior art is fixed, and the pipes need to be disassembled and reassembled when bending in the reverse direction, which is poor in convenience of use. In order to achieve the above purpose, the present invention provides the following technical solutions: a bending device for processing building materials, comprising a processing table, the top of which is rotatably provided with two pushing rollers, and a limiting sleeve matched with the pushing rollers is fixedly provided on the processing table, and a bidirectional bender matched with the limiting sleeve is provided on the processing table.

[0007] The bidirectional bender includes a plate seat arranged in the middle of the processing table, and the bottom of the plate seat is fixedly connected to a slide rail through two connecting frames, a motor seat is slidably connected in the slide rail, and a motor is fixedly installed in the motor seat, and a gear is fixedly arranged on the rotating shaft of the motor.

[0008] The plate seat is provided with two arc grooves, and the two arc grooves are staggered. The interiors of the two arc grooves are slidably connected with sliding seats, and the bottoms of the two sliding seats are fixedly connected with connecting plates. The bottoms of the connecting plates are provided with grooves corresponding to the gears, and one of the inner side walls of the grooves is provided with tooth surfaces meshing with the gears, and both ends of the grooves are provided with latch teeth for locking the gears.

[0009] The tops of the two slide seats are rotatably connected with bending wheels that cooperate with each other.

[0010] The processing table is provided with a bending reversing component.

[0011] Preferably, the bending reversing assembly includes a concave shell arranged along the middle of the processing table, the plate seat is located in the concave shell, and a rotating ring is fixedly connected to the plate seat, and the plate seat is rotatably connected along the limiting sleeve through the rotating ring.

[0012] A pipe rack is fixedly arranged at the bottom of the concave shell, and a rotating shaft is rotatably connected inside the pipe rack. Two plug-in blocks are fixedly connected to the side surface of the rotating shaft, and the two plug-in blocks are symmetrically distributed along the rotating shaft.

[0013] The bottom of the concave shell is provided with a slot for inserting the plug.

[0014] The surface of the plug block and the side edge of the plate seat are both fixedly provided with magnetic seats that cooperate with each other.

[0015] The bending wheel is provided with a gap filling component.

[0016] Preferably, the filling assembly includes a circular groove opened at the top of the bending wheel, and a pressure plate with a conical structure is screwed into the circular groove through a thread. A plurality of sliding grooves are annularly opened on the inner wall of the circular groove, and a push rod for cooperating with the pressure plate is slidably connected in the sliding groove.

[0017] A plurality of vertical grooves connected with the slide grooves are respectively provided on the wheel surface of the bending wheel, and a vertical shaft is arranged in the vertical groove. The bottom end of the vertical shaft is rotatably connected along the vertical groove, and the top end of the vertical shaft cooperates with the push rod.

[0018] The surface of the vertical shaft is rotatably connected with a roller.

[0019] Preferably, two triangular bars matching with the motor seat are slidably provided at the inner bottom of the slide rail, and a spring is provided at the bottom of the triangular bars.

[0020] Preferably, two handles are fixedly provided on the plate seat.

[0021] Preferably, the insert block, the plate seat and the corresponding magnetic seat are all installed by bolts.

[0022] Preferably, a convex ridge is fixedly provided on the top of the pressure plate.

[0023] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, the connecting plate is driven to rotate by gears, and the connecting plate is swung with one end as the center of the circle, so that one of the bending wheels is used as a fixed wheel to limit the steel pipe, and the other bending wheel is used as a moving wheel to bend the steel pipe. After the motor is controlled to reverse, the motor will slide to the other end along the slide rail, and the two bending wheels will interchange their functions. At this time, the bending direction of the steel pipe is opposite to the above-mentioned one. Compared with the existing non-adjustable bending structure, the above-mentioned connecting plate can switch the functions of the two bending wheels according to the difference of its own deflection point, so that the steel pipe can be quickly bent in the opposite direction without re-installing the steel pipe, and the deflection point of the connecting plate is quickly controlled by the forward and reverse rotation of the motor, which is convenient to use and improves the working efficiency.

[0024] In the present invention, by pushing the plate seat to flip 90° along the limiting sleeve and the concave shell, the plate seat is turned from horizontal to vertical, so that the bending direction of the two adjustable bending wheels is switched from left and right horizontal to up and down vertical. When shutting down, the plate seat can also be flipped to turn the bending area into the concave shell. Compared with the existing bending equipment with fixed structure, the above-mentioned flip plate seat can cooperate with the adjustable bending wheels to perform vertical bidirectional bending on the steel pipe without re-disassembling the steel pipe, which greatly improves the convenience of the bending operation. When transporting the equipment, the bending area is placed under the concave shell, which can avoid damage caused by external collisions on the one hand, and lower the center of gravity of the equipment on the other hand.

[0025] In the present invention, the pressure plate is rotated downward and the push rod is squeezed to slide outward along the slide groove, so that the push rod pushes the vertical axis and the roller to move and fit the steel pipe. Compared with the steel pipe pressure wheel with the existing wheel surface structure, the roller can move within the wheel surface and adaptably fit different steel pipes. On the one hand, effective contact between the bending wheel and the steel pipe is guaranteed to avoid deviation in the bending amount caused by the gap. On the other hand, when the tube surface of the steel pipe bending area is stretched or wrinkled, the roller can cooperate and roll to continuously bear the load, thus avoiding hard friction of the tube surface along the fixed wheel surface.
