Description

Technical Field

[0001] The invention belongs to the technical field of aluminum profile processing, and particularly relates to an aluminum profile used for a train windshield and a processing method thereof. Background Art

[0002] Train windshields are located at the connection between carriages and play an important role in isolating the inside and outside environment of the train and maintaining the temperature and comfort inside the train. Train windshields mainly include three types: iron windshields, rubber windshields and folding windshields. The folding windshield has a folding function and can be quickly unfolded when needed and folded when not needed to reduce air resistance. It has been widely used.

[0003] The folding windshield is usually composed of a tarpaulin and a mounting frame, wherein the mounting frame needs to be made of high-strength metal materials and needs to meet requirements such as impact resistance and pressure resistance. Aluminum alloy has the advantages of high strength, not easy to deform, good corrosion resistance, and easy processing, and is a high-quality production material for the mounting frame. The current folding windshield usually fixes the tarpaulin and the mounting frame with bolts, but due to the heavy weight of the tarpaulin, it is inconvenient to install. Summary of the invention

[0004] In view of the problems mentioned in the background technology, the purpose of the present invention is to provide an aluminum profile for a train windshield and a processing method thereof to solve the problems mentioned in the background technology.

[0006] An aluminum profile for a train windshield comprises a mounting frame and a tarpaulin. A plurality of sets of quick disassembly and assembly components are mounted between the mounting frame and the tarpaulin. The quick disassembly and assembly components comprise mounting parts and fixing parts. The mounting parts are mounted between the mounting frame and the tarpaulin. The fixing parts are mounted on the mounting frame. The fixing parts are detachably connected to the mounting parts.

[0007] As a preferred technical solution, the distances between any two adjacent groups of quick-disassembly and assembly components along the circumferential direction of the inner wall of the installation frame are equal.

[0008] As a preferred technical solution, the mounting member includes a connector 1 fixedly mounted on the mounting frame and a connector 2 fixedly mounted on the tarpaulin. The connector 1 and the connector 2 are matched and connected, and the fixing member and the connector 1 form a closed space that restricts the connector 2.

[0009] As a preferred technical solution, connecting part 1 includes a hook installed on the mounting frame, connecting part 2 includes a hanging ring installed on the tarpaulin, the hook includes rod 1 vertically installed on the inner wall of the mounting frame and rod 2 vertically installed on rod 1, and rod 2 and the hanging ring are located on both sides of rod 1.

[0010] As a preferred technical solution, the diameter of the hanging ring is greater than the length of the second rod.

[0011] As a preferred technical solution, the distance between the first rod and the edge of the installation frame close to the tarpaulin side is not less than the diameter of the hanging ring.

[0012] As a preferred technical solution, the fixing member includes a jack formed on the second rod and an elastic member fixedly installed on the inner wall of the installation frame. The telescopic direction of the elastic member is parallel to the first rod, and a plug rod is installed at the end of the elastic member. The plug rod is detachably inserted into the jack.

[0013] As a preferred technical solution, a plurality of installation holes for installation with the end of the train are formed on the other side of the installation frame opposite to the tarpaulin.

[0014] A processing method for an aluminum profile for a train windshield includes the following steps:

[0015] Step 1: Extrusion molding: Place the aluminum alloy blank into the extrusion die, and extrude an aluminum profile with a length equal to the perimeter of the finished product from the extrusion die.

[0016] Step 2: Marking: Mark the bending position on one side of the aluminum profile, mark the position of the corresponding hook according to the position of the hanging ring on the tarpaulin, and then mark the position of the corresponding fixing member according to the position of the hook.

[0017] Step 3: Trimming: Cut both ends of the aluminum profile into triangles to facilitate welding.

[0018] Step 4: Drilling: Drill installation holes on the side of the aluminum profile opposite to the installation of the tarpaulin.

[0019] Step 5: Bending: Bend sequentially at the bending marked positions.

[0020] Step 6: Shaping: Weld the ends of the bent aluminum profile into a rectangular installation frame.

[0021] Step 7: Installation: Weld the hook and the fixing member at the marked positions.
