Description

Technical Field

[0001] The present application relates to the technical field of aluminum tube processing, and in particular to a chamfering cutter head for metal tubes. Background Art

[0002] In the production of metal pipes, chamfering the pipe ends is a necessary process to avoid cuts to operators during use and to improve the quality of metal pipe products.

[0003] In traditional production processes, handheld grinders or cutters are used to chamfer the ends of metal tubes. This method has low production efficiency, poor quality stability, and poor chamfering effects. In addition, the heat dissipation during processing is poor, which makes the aluminum tube easily deformed during processing.

[0004] Therefore, it is necessary to provide a metal pipe chamfering cutter head to solve the above problems.

[0005] It should be noted that the above information disclosed in this Background section is only for understanding the background technology of the present application concept, and therefore, it may contain information that does not constitute prior art. Summary of the Invention

[0006] Based on the above problems existing in the prior art, the problem to be solved by the present application is: to provide a chamfering cutter head for metal pipes, which solves the problem of poor heat dissipation and easy deformation during processing.

[0007] The technical solution adopted by the present application to solve its technical problems is: a chamfering cutter head for metal pipes, comprising three mounting blocks, a support column, and a chamfering cutter; the three mounting blocks are circumferentially arranged on the outside of the support column, the chamfering cutter is arranged between two adjacent mounting blocks, and is located at one end of the support column, and the three mounting blocks are connected end to end in sequence; the length of the support column is greater than the length of the mounting block; the mounting block is a fan-shaped block, one end of the support column is set to be conical, and the chamfering cutter is provided with a blade on the side away from the support column; thus, one end of the support column is fixedly connected to the rotating motor, the end of the aluminum pipe is docked with the conical head of the support column, and the rotating motor drives the mounting block and the chamfering cutter to rotate through the support column, and the chamfering cutter chamfers the end of the aluminum pipe; there is a gap between the mounting seat composed of three mounting blocks, so that heat can be dissipated quickly, thereby avoiding overheating and deformation of the chamfering cutter during processing.

[0008] Furthermore, a right-angle groove is provided on the end face of the mounting block, and the right-angle groove passes through the end face of the mounting block. The right-angle groove divides the mounting block into volume block one and volume block two, and the volume block one is connected to the volume block two of another adjacent mounting block by bolts; thus, the right-angle groove not only provides an installation environment, but also increases the ventilation area and accelerates the heat dissipation speed.

[0009] Furthermore, a plurality of mounting grooves are opened on the circumferential side of the support column, and a plurality of mounting plates are arranged on the circumferential side of the support column; one of the mounting plates is arranged between two adjacent mounting grooves, and the mounting plates are clamped with the mounting blocks in a one-to-one correspondence; thus, the mounting grooves are correspondingly connected to the gaps between the two mounting blocks, one of the mounting grooves is used to place the chamfering knife, and the other mounting grooves are used to discharge waste materials.

[0010] Furthermore, a straight rib 1 is provided on the outer circumference of the mounting plate, and the long side of the straight rib is parallel to the axis of the support column. A straight rib 2 is provided on the inner arc side circumference of the mounting block, and one straight rib 2 is located between two adjacent straight ribs 1; thus, the staggered connection formed by straight rib 1 and straight rib 2 can strengthen the connection between the mounting block and the support column, reduce the position error caused by the lag force when the mounting block rotates, and indirectly extend the service life of the device.

[0011] Furthermore, a plurality of splayed ribs are axially arranged on the outer side of the mounting plate; thus, the splayed ribs increase the resistance to tilting, which is used to offset the inertial forces in the horizontal and vertical directions caused by the rotation between the mounting block and the support column, thereby enhancing the stability between the mounting block and the support column.

[0012] Furthermore, the side of the chamfering cutter is provided with an arc rib; thus, the arc rib increases the friction between the chamfering cutter and the mounting block, strengthens the stability of the mounting block clamping the chamfering cutter, and indirectly reduces the failure rate of aluminum tube processing.

[0013] The beneficial effects of the present application are: a chamfering cutter head for metal tubes provided by the present application is provided with three mounting blocks, a support column, and a chamfering cutter. One end of the support column is fixedly connected to a rotating motor, and the end of the aluminum tube is docked with the conical head of the support column. The rotating motor drives the mounting block and the chamfering cutter to rotate through the support column, and the chamfering cutter chamfers the end of the aluminum tube. There is a gap between the mounting seat composed of the three mounting blocks, so that heat can be dissipated quickly, thereby avoiding overheating and deformation of the chamfering cutter during processing.

The rotating motor drives the mounting block 1 and the chamfering knife 3 to rotate through the support column 2, and the chamfering knife 3 chamfers the end of the aluminum tube; there is a gap between the mounting seat composed of three mounting blocks 1, so that heat can be dissipated quickly to avoid overheating and deformation of the chamfering knife 3 during processing.

[0031] Reference Figure 3 A right-angle groove 11 is provided on the end face of the mounting block 1. The right-angle groove 11 passes through the end face of the mounting block 1 and divides the mounting block 1 into volume block 1 111 and volume block 2 112. Volume block 1 111 is connected to volume block 2 112 of another adjacent mounting block 1 by bolts. Thus, the right-angle groove 11 not only provides an installation environment, but also increases the ventilation area and accelerates the heat dissipation speed.
