[0004] In the above patent, the processing of annular protrusions on aluminum tubes of different models is achieved, but the positioning device and the die device cannot be moved, and the reserved size of the aluminum tube cannot be adjusted to meet different processing requirements of the aluminum tube.

[0005] Therefore, it is necessary to provide a heater pipe cold heading device to solve the above problems.

[0006] 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

[0007] Based on the above problems existing in the prior art, the problem to be solved by this application is: to provide a heater pipe cold heading device, which solves the problem that different processing requirements of aluminum pipes cannot be met due to the fact that the reserved size of the aluminum pipe cannot be adjusted.

[0008] The technical solution adopted by the present application to solve the technical problem is: a heater pipe cold heading device, comprising a workbench, a frame, a die mechanism, a positioning mechanism, and a header mechanism; the frame is arranged on the workbench, the die mechanism, the positioning mechanism, and the header mechanism are arranged between the workbench and the frame, the bottom of the die mechanism is fixed to the workbench, the positioning mechanism is located on one side of the die mechanism and is slidably connected to the frame, the header mechanism is located on a side of the positioning mechanism away from the die mechanism, and the bottom is slidably mounted on the workbench;

[0009] Wherein: two slide rails are provided at the top of the frame, a movable slot is provided at the top of the frame, the movable slot is located between the two slide rails, and the long side of the movable slot is parallel to the long side of the slide rail;

[0010] The positioning mechanism includes a mounting frame, an electric telescopic rod, a support arm, and a baffle; the bottom of the mounting frame is mounted on a slide rail through a sliding connection, the bottom of the electric telescopic rod is fixedly mounted on the top of the frame, and one end is fixedly connected to the mounting frame; the support arm is located in a movable groove, and one side of the support arm is slidably mounted on the inside of the mounting frame, and a pneumatic telescopic rod is fixedly installed on the top of the mounting frame, one end of the pneumatic telescopic rod is placed inside the mounting frame and fixedly connected to the support arm; one end of the pneumatic telescopic rod of the support arm is fixedly connected to the baffle, and the baffle is located between the workbench and the frame; thus, the electric telescopic rod controls the movement of the mounting frame on the frame, and its movement trajectory is parallel to the axis of the aluminum tube to be processed, and the support arm follows the movement in the movable groove, thereby realizing the adjustment of the distance between the baffle and the die pressing mechanism, that is, adjusting the length reserved when the aluminum tube is placed, so as to meet subsequent processing requirements.

[0011] Furthermore, the mounting frame includes a hollow frame, a vertical plate, and a slide bed; the bottom of the hollow frame and the slide rail are a matching structure, the vertical plate is arranged inside the hollow frame, and one side is fixedly connected to the inner wall of the hollow frame; the slide bed is fixedly installed on the side of the vertical plate close to the die pressing mechanism, and the side of the support arm is installed with the slide bed through a sliding connection.

[0012] Furthermore, the baffle is an L-shaped plate, and the side surface of one end of the baffle is perpendicular to the side surface of the support arm; thus, the baffle can be used to determine whether the support arm is perpendicular to the workbench, thereby avoiding affecting the subsequent positioning of the aluminum tube.

[0014] Furthermore, pipelines, multiple arc-shaped grooves, and limit grooves are provided on opposite sides of the two mold beds; the arc-shaped grooves and limit grooves are respectively connected with the pipelines; the arc-shaped grooves of the two mold beds correspond one to one to form an annular groove, and the limit grooves are located on the side of the arc-shaped groove away from the baffle; thus, the pipeline is used to place a corresponding aluminum tube, one end of the aluminum tube passes through the mold bed and rests against the baffle, and the part of the aluminum tube located between the mold bed and the baffle is the reserved length; the subsequent pier head mechanism pushes the reserved part of the aluminum tube into the mold bed, causing the aluminum tube to be locally deformed and enter the arc-shaped groove for forming.

[0015] Furthermore, a limiting member is placed in the limiting groove, and the limiting member and the limiting groove are both conical; the smaller end of the limiting groove is away from the arc-shaped groove, and the inner diameter of the limiting member is the same as the inner diameter of the pipeline; ball grooves are evenly opened on the outer side of the limiting member, and a sphere is installed between the inner wall of the limiting groove and the outer wall of the limiting member through a rolling connection, and the sphere and the ball groove are a one-to-one matching mechanism; thus, the aluminum tube is embedded in the limiting member at the same time when it is installed on the pipeline; when the two mold beds are engaged, the two limiting members surround the aluminum tube; when the subsequent pier head mechanism pushes the aluminum tube, the aluminum tube drives the limiting member to move, and the sphere follows the conical surface of the limiting groove to move closer to the aluminum tube, thereby pushing the limiting member to cooperate and clamp the pipe material, preventing the pipe material from being displaced during cold heading, affecting the subsequent qualified rate of finished products, and at the same time replacing manual auxiliary control, saving manpower.

[0016] Furthermore, branches are provided at both ends of the limiting member, and the end of the branch away from the limiting member is clearance-matched with the mold bed; thus, the branch limits the limiting member from moving out of the limiting groove, but does not limit the limiting member from moving within the limiting groove.
