Description

Technical Field

[0001] This utility model relates to the technical field of hot air comb production equipment, and in particular to a hot air comb aluminum tube punching machine. Background Technology

[0002] The hot air comb aluminum tube punching machine is a key piece of equipment in the hot air comb production process. It is mainly used to precisely punch holes in aluminum tubes (the core airflow channel component of the hot air comb) to meet the performance requirements of uniform airflow and structural strength. Its working principle is to process through holes of specific size and distribution on the surface of the aluminum tube by the cooperation of the mold and the punch. The processing accuracy directly affects the airflow efficiency and safety of the hot air comb. Existing hot air comb aluminum tube punching machines typically employ two common layouts for their ejector and hydraulic mechanisms: one where the ejector and hydraulic mechanisms are mounted on the worktable, and after the aluminum tube is placed in the mold, the hydraulic mechanism drives the ejector component to push the tube into the mold to complete the punching; the other where the hydraulic mechanism is located below the worktable, using a retracting hydraulic cylinder to move the mold or aluminum tube downwards, allowing the tube to enter the mold for processing. To prevent punching deviations due to positional shifts during the tube's descent, existing devices typically include a hooked vertical rod on the unloading platform. This rod descends synchronously with the aluminum tube, contacting its surface via the hook to move it downwards, theoretically ensuring that the bottom of the tube remains in contact with the placement surface. However, in practical applications, this structure has obvious defects: because the contact point between the hook and the aluminum tube is singular, mostly at a certain position on the side of the aluminum tube, the aluminum tube is prone to unbalanced force. Especially when the aluminum tube has a slight bend or uneven wall thickness, the unilateral thrust will cause the aluminum tube to tilt, resulting in a gap between its bottom and the placement surface or excessively tight local contact, which will eventually cause the punching position to shift, affecting the product qualification rate. At the same time, the hard contact between the hook and the aluminum tube may also leave scratches on the tube surface, increasing the workload of subsequent grinding processes.

[0003] Therefore, a hot air comb aluminum tube punching machine was designed. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing a hot air comb aluminum tube punching machine. It solves the problem in the two layouts of existing hot air comb aluminum tube punching machines where the vertical rod with a hook on the feeding chassis has a single, consistent contact point, resulting in unbalanced force on the aluminum tube and causing punching deviation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A hot air comb aluminum tube punching machine includes a machine tool, a mold fixed on the top of the machine tool, a plurality of punches fixed on the top of the machine tool and distributed around the mold, a positioning component fixedly installed on the machine tool and penetrating the mold to position the aluminum tube, and a placement component slidably installed in the mold for fixing the aluminum tube.

[0006] Preferably, the placement component includes a hollow tube, a vertical rod is fixedly installed on the top of the hollow tube, and a pressure ring is rotatably installed on the top of the vertical rod.

[0007] Preferably, a hydraulic cylinder is fixedly installed on the bottom inner wall of the machine tool, and the output shaft of the hydraulic cylinder is fixedly connected to the bottom of the hollow tube.

[0008] Preferably, the positioning component includes a positioning shaft, and a guide block is fixedly installed on the top of the positioning shaft. The guide block is designed to be smaller at the top and larger at the bottom, so that the aluminum tube can be easily inserted into the positioning shaft.

[0009] Preferably, a discharge pipe is fixedly installed at the bottom of the positioning shaft, a rectangular groove is opened on the outer wall of the hollow tube, the discharge pipe passes through the rectangular groove and is slidably connected to the rectangular groove, and the end of the discharge pipe is fixedly connected to the collection box.

[0010] Preferably, the outer wall of the positioning shaft has multiple sets of slots II, and the outer wall of the mold has multiple sets of slots I, with the multiple sets of slots II and slots I respectively adapted to the corresponding punches.

[0011] Preferably, the top of the mold has a placement groove, and the hollow tube is slidably connected to the placement groove and the positioning shaft respectively, so that the hollow tube can slide stably along the placement groove and the positioning shaft.

[0012] Preferably, the top of the vertical rod is provided with a protrusion to limit the rotation angle of the pressure ring.

[0013] Preferably, the top opening of the placement groove is the largest, gradually narrowing downwards to guide the sliding of the hollow tube.

[0014] Preferably, the pressure ring can be rotated to adjust its contact state with the aluminum tube, and together with the vertical rod, it can press the top of the aluminum tube.

[0015] Compared with the prior art, the present invention has the following beneficial effects: This invention features a positioning component that allows the positioning shaft to penetrate the mold and fit tightly against the inner wall of the aluminum tube. The guide block, via a conical surface, can calibrate concentricity and reduce initial deviation. A rotatable pressure ring forms a bidirectional fixation with the hollow tube, and with the help of a protrusion for limiting movement, it prevents the aluminum tube from tilting during movement. This effectively solves the problem of unbalanced force at a traditional single contact point, thereby minimizing punching errors caused by unbalanced force and improving the product yield.

Example

[0023] Please see Figure 1-6 A hot air comb aluminum tube punching machine includes a machine tool 1, a mold 2 fixed to the top of the machine tool 1, multiple punches 11 fixed to the top of the machine tool 1 and distributed around the mold 2, a positioning component 4 fixedly installed on the machine tool 1 and penetrating the mold 2 to position the aluminum tube, and a placement component 3 slidably installed inside the mold 2 to fix the aluminum tube; the placement component 3 includes a hollow tube 30, a vertical rod 31 fixedly installed on the top of the hollow tube 30, and a pressure ring 32 rotatably installed on the top of the vertical rod 31; a hydraulic cylinder 12 is fixedly installed on the inner wall of the bottom of the machine tool 1, and the output shaft of the hydraulic cylinder 12 is fixedly connected to the bottom of the hollow tube 30; the positioning component 4 includes a positioning shaft 40, a guide block 43 fixedly installed on the top of the positioning shaft 40, the guide block 43 being designed with a smaller top and a larger bottom to facilitate the aluminum tube being fitted into the positioning shaft 40; a discharge pipe 42 is fixedly installed on the bottom of the positioning shaft 40, and the outer wall of the hollow tube 30 is provided with A rectangular groove 33 is formed, through which a discharge pipe 42 is slidably connected. The end of the discharge pipe 42 is fixedly connected to a collection box. Multiple sets of slots 41 are formed on the outer wall of the positioning shaft 40, and multiple sets of slots 21 are formed on the outer wall of the mold 2. The multiple sets of slots 41 and slots 21 are respectively adapted to the corresponding punches 11. A placement groove 22 is formed on the top of the mold 2. The hollow tube 30 is slidably connected to the placement groove 22 and the positioning shaft 40, so that the hollow tube 30 can slide stably along the placement groove 22 and the positioning shaft 40. A protrusion 311 is provided on the top of the vertical rod 31 to limit the rotation angle of the pressure ring 32. The top opening of the placement groove 22 is the largest and gradually tightens downward, which guides the sliding of the hollow tube 30. The pressure ring 32 can be rotated to adjust the contact state with the aluminum tube, and together with the vertical rod 31, it can press the top of the aluminum tube to enhance the fixing effect of the aluminum tube.

[0024] The positioning shaft 40 of the positioning component 4 passes through the mold 2 and fits tightly with the inner wall of the aluminum tube to achieve radial reference positioning; the top guide block 43 is designed with a smaller top and a larger bottom, which can guide the aluminum tube to be quickly inserted and automatically calibrate the concentricity of the aluminum tube and the positioning shaft 40 through the conical surface, reducing the initial placement deviation; the pressure ring 32 of the placement component 3 can be rotated to adjust the contact state with the aluminum tube, and together with the hollow tube 30, it forms a two-way fixing structure of top pressing and bottom support, which prevents the aluminum tube from tilting during up and down movement; the protrusion 311 on the top of the vertical rod 31 restricts the excessive rotation of the pressure ring 32, ensuring that the pressure ring 32 remains fixed after reset. Pressed against the edge of the aluminum tube, the problem of unbalanced force caused by the traditional single contact point fixation is solved, thereby reducing the punching deviation caused by the aluminum tube offset; the hollow tube 30 is simultaneously slidably connected to the placement groove 22 and the positioning shaft 40 of the mold 2, forming a double guide; the tightening design of the placement groove 22, which is wider at the top and narrower at the bottom, further guides the hollow tube 30 to move in a straight line, avoiding jamming or shaking when sliding up and down, and effectively protecting the surface of the aluminum tube from scratches; the hydraulic cylinder 12, as a power source, can realize the automated lifting and lowering of the aluminum tube into the mold 2, processing, and removal, replacing the traditional manual pushing, and greatly shortening the transfer time of a single aluminum tube.

[0025] Workflow The hydraulic cylinder 12 is in the extended state, the top of the hollow tube 30 is located at the top of the placement groove 22 of the mold 2, the guide block 43 of the positioning shaft 40 is exposed above the top of the hollow tube 30, and the pressure ring 32 is in the rotating open state. The operator holds the aluminum tube to be processed. Under the guidance of the top guide block 43 of the positioning shaft 40, the shape of the aluminum tube, which is smaller at the top and larger at the bottom, makes it easy to quickly insert the aluminum tube. The aluminum tube is then placed vertically on top of the hollow tube 30. Rotate the pressure ring 32 at the top of the vertical rod 31 to reset it. At this time, the pressure ring 32 is pressed against the top edge of the aluminum tube, clamping the aluminum tube between the pressure ring 32 and the hollow tube 30. Start the hydraulic cylinder 12 to retract its output shaft, which drives the hollow tube 30 to slide downward along the placement groove 22 and positioning shaft 40 of the mold 2, and gradually feeds the aluminum tube into the mold 2. When the aluminum tube is fully inserted into the mold 2 and the position of the aluminum tube to be punched is aligned with the first slot 21 of the mold 2 and the second slot 41 of the positioning shaft 40, the hydraulic cylinder 12 stops retracting. At this time, the punches 11 distributed around the mold 2 start and punch the aluminum tube through the first slot 21 and the second slot 41. The waste generated by punching is discharged into the collection box through the discharge pipe 42. The discharge pipe 42 slides along the rectangular groove 33 with the hollow tube 30 and does not affect the downward movement process. After punching is completed, the hydraulic cylinder 12 extends, driving the hollow tube 30 to move the aluminum tube upward until it returns to the initial position; the rotating pressure ring 32 opens, and the processed aluminum tube is removed, completing one processing cycle.

[0026] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations or modifications.
