Description

Technical Field

[0001] The utility model relates to the technical field of plate processing, in particular to a rock wool plate hole punching machine. Background Art

[0002] Rockwool board is a thermal insulation material that can be combined with exterior panels and base panels to create thermal insulation composite panels. In thermal insulation composite panels, the rockwool board is placed between the exterior panels and base panels, and the three panels are connected by adhesives or fasteners. To further strengthen the connection between the exterior panels and base panels, mechanical fasteners are usually required to strengthen the connection between the exterior panels and base panels. To facilitate the installation of fasteners, holes are pre-drilled in the rockwool board. The fasteners are placed in the holes in the rockwool board, and the ends of the fasteners are mechanically connected to the exterior panels and base panels respectively.

[0003] Currently, drilling holes in rock wool boards is usually done manually, which is inefficient and difficult to maintain consistent hole position accuracy, thus affecting subsequent connections. Utility Model Content

[0004] In order to solve the above problems existing in the prior art, the utility model provides a rock wool board hole punching machine which is easy to use, has high hole punching efficiency and high hole position accuracy.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A rock wool board hole punching machine comprises a frame, a workbench is provided on the top of the frame, a first limiting mechanism is provided at both ends of the workbench, and a second limiting mechanism is provided at the rear end of the workbench; a lifting bracket is provided on the upper side of the workbench, and a lifting mechanism is provided at both ends of the workbench that is lifted and lowered by the lifting bracket; a plurality of hole punching components distributed corresponding to the positions of holes to be punched in the rock wool board are provided on the lifting bracket, and the hole punching components include a motor and a round tube cutter detachably connected to the motor shaft end; a blanking hole is provided on the workbench directly below the round tube cutter.

[0007] By adopting the above technical solution: the lifting mechanism drives the lifting bracket to rise to the initial position, and the single rock wool board is placed on the workbench. The left and right sides of the rock wool board are limited by the first limiting mechanism, and the rear side is limited by the second limiting mechanism. Then the lifting mechanism drives the lifting bracket to descend, and at the same time the motor drives the round tube cutter to rotate. When the round tube cutter descends and passes through the rock wool board, a through hole is opened in the rock wool (the through hole is used to install fasteners). Then the lifting bracket is reset to the initial position, the rock wool board with holes opened is removed, and the rock wool board to be opened is installed. Through this type of hole opening machine, all the holes on the rock wool board can be cut at one time, and the hole opening component can be installed according to the actual requirements to ensure that the hole position on each rock wool board is consistent.

[0008] Preferably, the first limiting mechanism includes a connecting base, side baffles, and a screw rod, the side baffles being horizontally slidably connected to the connecting base via a guide rod, the inner end of the screw rod being rotatably connected to the side baffles, the screw rod being parallel to the guide rod and threadedly connected to the connecting base, and the outer end of the screw rod being fixed with a wrench seat. The side baffles in the two first limiting mechanisms are arranged parallel to each other. The screw rods are rotated by the wrench seat, thereby adjusting the position of the side baffles to meet the limiting requirements of rock wool boards of different sizes.

[0009] Preferably, the second limiting mechanism comprises a horizontal cylinder fixed to the bottom of the workbench and a rear baffle fixed to the end of the horizontal cylinder shaft. A push block is provided on the front side of the rear baffle, which is slidably connected to the rear baffle via an adjustment rod, and a locking bolt is provided on the side of the adjustment rod. The position of the push block is adjusted by the adjustment rod to meet the rear positioning requirements of rock wool boards of different sizes. After the rock wool board is drilled, the push block is driven by the horizontal cylinder to push the rock wool board forward a certain distance, thereby facilitating the operator to conveniently and safely remove the rock wool board.

[0010] Preferably, the lifting mechanism includes a cylinder seat fixed at both ends of the frame and several lifting cylinders, the lifting cylinders on each cylinder seat are configured into two groups, the axial ends of the lifting cylinders face upward and extend and retract synchronously; the two ends of the lifting bracket are respectively fixedly connected to the axial ends of the lifting cylinders.

[0011] Preferably, the lower end of the circular tube cutter is provided with tooth blades distributed along the circumferential direction, and the upper end of the circular tube cutter is fixed with a connecting sleeve, and the connecting sleeve is coaxially connected to the motor via a coupling. When the circular tube cutter rotates and descends, the tooth blades rotate to cut a through hole in the rock wool board.

[0012] Preferably, the upper end of the coupling is sleeved onto the motor shaft and fastened by a first bolt, while the lower end of the coupling extends to form a rectangular projection. The inner hole of the connecting sleeve is configured as a rectangular hole adapted to fit the rectangular projection, and the rectangular hole is sleeved onto the rectangular projection and fastened by a second bolt. This connection structure facilitates replacement of the round tube cutter.

[0013] Preferably, an annular retaining ring is provided on the inner wall of the circular tube cutter, a pressure block is provided on the upper side of the annular retaining ring, a compression spring is provided between the pressure block and the top end of the circular tube cutter, and a pressure rod is provided at the center of the lower end of the circular tube cutter, the upper end of the pressure rod is connected to the pressure block. During the circular tube cutter cutting process, the material cut from the rock wool board will remain in the circular tube cutter and abut against the pressure rod, causing the compression spring to contract. When the rock wool board is completely cut through, the elastic force of the compression spring pushes the material remaining in the circular tube cutter downward, and the material falls from the blanking hole.

[0014] Preferably, the upper end of the pressure rod is rotatably connected to the pressure block, and a bearing seat is provided at the center of the upper end of the pressure block, wherein a bearing is provided in the bearing seat, and the upper end of the pressure rod is connected to the bearing. When the circular tube cutter rotates, the pressure rod rotates relative to the circular tube cutter via the bearing, thereby preventing friction between the lower end of the pressure rod and the rock wool board during the circular tube cutter drilling process.

[0015] Therefore, the utility model has the beneficial effects of being easy to use, high in hole-drilling efficiency and high in hole position accuracy. BRIEF DESCRIPTION OF THE DRAWINGS
