Description

Technical Field

[0001] The present invention relates to the field of automotive component processing, and particularly to a laser coding and extrusion flaring device and working method for aluminum profile tubular beams. Background Art

[0002] Aluminum profile tubular beams are a common type of part in automotive components. The demand for lightweighting promotes their use in aluminum profile body frames, chassis suspensions, and battery pack brackets. Flaring both ends of the tubular beam is for lap joint assembly. The traditional process requires batch flaring of both ends and separate printing of marks, with relatively low efficiency. Chinese Patent CN113275891A discloses a copper tube flaring device, method, and copper tube processing equipment. Two groups of flaring clamping cylinders are used to control two flaring clamping jaws respectively, making the two flaring clamping jaws approach each other to clamp the copper tube, and then the flaring operation is carried out. However, the tubular beam is a flat part with multiple openings, and it is necessary to flare multiple openings at both ends simultaneously. Also, it is necessary to position the tubular beam first. The positioning requires first positioning the end face of the tubular beam and then flaring, so as to ensure accurate positioning. Therefore, a flaring device matching this operation is needed. Summary of the Invention

[0003] In view of this, the purpose of the present invention is to provide a laser coding and extrusion flaring device for aluminum profile tubular beams, which solves the problems in the background art.

[0004] Based on the above purpose, the present invention provides a laser coding and extrusion flaring device for aluminum profile tubular beams, including a pedestal. On the left and right ends of the top of the pedestal, a left flaring mechanism and a right flaring mechanism are respectively arranged. Horizontally distributed on the top of the pedestal between the left flaring mechanism and the right flaring mechanism are a plurality of support reference blocks for fitting and placing the tubular beam. On one side of the support reference blocks, a pressing mechanism is arranged. On the top of the pedestal, on the left side of the right flaring mechanism, a positioning mechanism for the end face of the tubular beam is arranged. On the top of the pedestal, on the left side of the positioning mechanism, a laser coding mechanism is arranged. The positioning mechanism includes a retracting cylinder that pushes and pulls back and forth on the top of the pedestal. The front output end of the retracting cylinder is connected to a positioning cylinder that pushes and pulls left and right. The bottom of the positioning cylinder is slidably matched with the slide rail on the top of the pedestal through a slider. The right output end of the positioning cylinder is connected to a positioning strip. The front end of the positioning strip can extend to the left side of the right flaring mechanism. On the left side of the front end of the positioning strip, a limiting head is arranged. The retracting cylinder pushes the positioning cylinder forward, and the positioning cylinder pulls the positioning strip to the left, and the limiting head contacts and limits the right end face of the tubular beam.

[0005] Preferably, the left flaring mechanism includes a left propulsion servo motor arranged on the top of the pedestal. The right output end of the left propulsion servo motor is connected to a flaring die head. The bottom of the flaring die head is slidably matched with the slide rail on the top of the pedestal through a slider.

[0006] Preferably, the right flaring mechanism includes a right propulsion servo motor disposed on the top of the pedestal. The left output end of the right propulsion servo motor is also connected to a flaring die head. The bottom of the flaring die head is slidably engaged with the slide rail on the top of the pedestal through a slider.

[0007] Preferably, the flaring die head includes a frame that can fit around the end face of the pipe beam. A plurality of flaring extrusion heads matching the pipe beam are arranged inside the frame. The frame is wrapped around the pipe beam to achieve fitting and positioning, and the flaring extrusion heads extend into the pipe beam for flaring.

[0008] Preferably, the laser coding mechanism includes a coding propulsion servo motor that moves back and forth disposed on the top of the pedestal. The rear output end of the coding propulsion servo motor is connected to an L-shaped bracket. A laser coder is arranged on the top of the L-shaped bracket. The L-shaped bracket is slidably engaged with the slide rail on the top of the pedestal through a slider. The coding propulsion servo motor moves the L-shaped bracket forward, so that the laser coder faces downwards towards the pipe beam for coding.

[0009] Preferably, the pressing mechanism includes a rotary pressing cylinder disposed on the top of the pedestal. The top output end of the rotary pressing cylinder is connected to a pressing arm, and the pressing arm is arranged corresponding to the support reference block up and down.

[0010] Preferably, a laser sensor is arranged on the top of the pedestal between a plurality of support reference blocks.

[0011] Preferably, fences are arranged on the top of the pedestal on the other three sides except the front side, and a safety induction grating is arranged on the front side of the fences.

[0012] A working method of an aluminum profile pipe beam laser coding and extrusion flaring device includes the following steps: Step 1, first, the retracting cylinder pushes the positioning cylinder forward, and the positioning cylinder pulls the positioning bar to the left to move the limiting head to the same plane as the support reference block; Step 2, then the pipe beam is manually placed on the support reference block, and the right end of the pipe beam contacts the limiting head for limiting; Step 3, then the pressing mechanism presses the pipe beam, and the laser coding mechanism codes the surface of the pipe beam; Step 4, finally, the left flaring mechanism moves to the right and the right flaring mechanism moves to the left to flare the left and right ends of the pipe beam simultaneously.

[0013] Advantages of the present invention: In the present invention, the pipe beam is placed on the support reference block in a fitting manner. First, the positioning mechanism is used to position the position. The positioning mechanism drives the positioning cylinder to push forward through the retracting cylinder. The positioning cylinder drives the positioning strip to pull leftward. The positioning strip limits and positions the pipe beam through the limiting head. After positioning, the pipe beam is clamped by the clamping mechanism. After the position of the pipe beam is positioned and fixed, the retracting cylinder drives the positioning cylinder to pull backward, and the positioning cylinder drives the positioning strip to push rightward, so that the positioning mechanism does not interfere with the work of the right flaring mechanism and the laser coding mechanism. After positioning, limiting, clamping and fixing, the surface of the pipe beam is laser-coded by the laser coding mechanism. Finally, the left and right flaring mechanisms simultaneously flare the two ends of the pipe beam. In this way, the end face of the pipe beam can be positioned first, and the positioning is accurate to ensure the accuracy of flaring, and the coding and flaring operations can be carried out efficiently and quickly. In the left flaring mechanism of the present invention, the frame of the flaring die head is wrapped around the left end of the pipe beam in a fitting manner by the left propulsion servo motor, and the flaring extrusion head is inserted into the pipe beam to flare. In the right flaring mechanism, the frame of the flaring die head is wrapped around the right end of the pipe beam in a fitting manner by the right propulsion servo motor, and the flaring extrusion head is inserted into the pipe beam to flare. The flaring die head slides on the slide rail of the pedestal through the slider, so the flaring efficiency is high, the effect is good, and the flaring process is stable and accurate. In the laser coding mechanism of the present invention, the slider of the L-shaped bracket is pulled forward on the slide rail at the top of the pedestal by the coding propulsion servo motor, so that the L-shaped bracket moves to the top of the pipe beam, and then the laser coder codes the surface of the pipe beam. In the clamping mechanism of the present invention, the rotating clamping cylinder drives the pressing arm to press down to accurately fix the position of the pipe beam together with the support reference block. A laser sensor is also provided on the pedestal of the present invention to sense the presence of the pipe beam, and a fence is provided to avoid surrounding interference, and a safety induction grating is provided to protect the safety of the staff.
