Description

Technical Field

[0001] The utility model relates to the technical field of aluminum tube production, in particular to an angle changing device for an outer scraper in aluminum tube production. Background Art

[0002] Aluminum is a metal element with the symbol Al and the atomic number 13. Its single substance is a silvery-white light metal. It is ductile. The products are often made into rods, sheets, foils, powders, strips and wires. In humid air, it can form an oxide film to prevent metal corrosion. Aluminum tube is a high-strength hard aluminum, which can be strengthened by heat treatment. It has medium plasticity in annealing, just quenching and hot state, good spot welding weldability, and tends to form intergranular cracks when using gas welding and argon arc welding. The cutting performance of aluminum tube is good after quenching and cold work hardening, but poor in the annealing state. The corrosion resistance is not high, and anodizing and painting methods or aluminum coating on the surface are often used to improve the corrosion resistance. It can also be used as a mold material.

[0003] Aluminum is widely used due to its high strength and good economy. At present, in the production process of aluminum tubes, aluminum tubes need to be welded. However, before welding, an external scraper is needed to remove burrs in the welding area. Conventional external scrapers are fixed on the frame, and the position of the scrapers contacting the aluminum tube is difficult to adjust, so the scraping effect on the burrs on the outer wall of the aluminum tube is poor. Utility Model Content

[0004] In order to solve the problem that in the above-mentioned general aluminum tube production process, the position of the outer scraper is difficult to flexibly adjust, resulting in poor burr scraping effect on the aluminum tube, and to achieve the above purpose of improving the burr scraping effect, the utility model is implemented through the following technical scheme: an angle changing device for an outer scraper for aluminum tube production, comprising a plate frame, a supporting block is fixedly provided at the front end of the plate frame, a first shaft sleeve is fixedly provided at the top right side of the supporting block, and a changing mechanism for changing the direction of the outer scraper is movably connected to the right end of the supporting block.

[0005] Furthermore, the direction-changing mechanism includes a first bolt rotatably connected to the first sleeve, a first supporting plate slidably connected to the right wall of the supporting block, the first supporting plate right wall being slidably connected to the second supporting plate, the first supporting plate right wall being fixedly provided with a second sleeve, the second sleeve inner cavity being rotatably connected to the second bolt, a connecting rod slidably inserted into the interior of the second supporting plate, an external scraper being fixed at the bottom end of the connecting rod, and a positioning bolt being threadedly connected to the right wall of the second supporting plate.

[0006] Furthermore, the right wall of the supporting block is provided with a vertical groove for the first supporting plate to slide up and down, and the first bolt is threadedly connected to the first supporting plate. By adjusting the rotation of the first bolt, the first supporting plate can be controlled to drive the outer scraper to move upward or downward; it also includes a welding mechanism fixedly arranged at the front end of the supporting block, and the welding mechanism includes a connecting block, a bracket fixedly arranged at the right end of the connecting block, a clamp fixedly arranged at the right end of the bracket, and a welding head close to the outer scraper is fixedly clamped on the clamp.

[0007] Furthermore, the right wall of the first supporting plate is provided with a longitudinal groove for the second supporting plate to slide forward and backward, and the left wall of the second supporting plate includes a threaded engaging portion sleeved on the outer periphery of the second bolt. By adjusting the rotation of the second bolt, the second supporting plate can be controlled to drive the outer scraper to move forward or backward; the positioning bolts include at least two, and the positioning bolts are abutted and connected to the surface of the connecting rod, thereby ensuring the stability of the outer scraper when scraping burrs.

[0008] Compared with the prior art, the utility model has the following beneficial effects:

[0009] 1. The angle changing device for the outer scraper of the aluminum tube production connects the outer scraper to the connecting rod, which is fixed on the second support plate by the positioning bolt. The first bolt is used to adjust the forward and backward movement of the first support plate, and the second bolt is used to adjust the up and down movement of the second support plate, so that the forward and backward movement of the outer scraper can be indirectly controlled according to production needs.

[0010] 2. The aluminum tube production external scraper angle changing device can adjust the position of the external scraper by adjusting the first bolt and the second bolt before welding, so that the external scraper can contact the aluminum tube and form the required angle. This design allows the position of the external scraper to be flexibly adjusted, so as to better scrape off burrs. BRIEF DESCRIPTION OF THE DRAWINGS
