Description

Technical Field

[0001] The utility model belongs to the field of machining technology and relates to an improvement of a packaging and transportation tool for special metal products. Background Art

[0002] When shipping aluminum profiles of rail cars, wooden frames are required for packaging. The specific packaging method is to first place the lower pallet, then place the profiles on the lower pallet, then set up the side plates, place the upper cover plate, and then nail to fasten the frame. Since the daily packaging quantity is very large, the workload of manual nailing is even more huge. The nails need to be nailed on the upper cover plate and the side plates, as well as on the side plates and the lower pallet. Since the width of the side plate is 30 mm, when nailing, it is necessary to nail through the upper cover plate to connect the side plate and nail through the side plate to connect the lower pallet according to experience. The distance control of this manual operation step is very limited, and it often happens that the nails are nailed off position and cannot be nailed on the side plate. There is also a possibility that due to human negligence, the nails are nailed obliquely onto the surface of the profile, causing nail damage to the profile surface, bringing serious quality problems and problems with the stability of the wooden frame.

[0003] In summary, the problems existing in the prior art are as follows:

[0004] (1) When packaging the wooden frame of the aluminum profile of the rail car, the workload of nailing is huge, and the worker cannot ensure that the nailing position is in the center of the side plate.

[0005] (2) The nails are nailed off position, resulting in the side plate, the upper cover plate and the lower pallet not being firmly connected together, causing the phenomenon of loose packaging.

[0006] (3) The nails are nailed obliquely onto the surface of the profile, causing nail damage to the profile surface and the profile being directly scrapped. Summary of the Invention

[0007] The purpose of the utility model is to provide a general nail alignment device for packaging the wooden frame of the aluminum profile of the rail car, which can reduce the huge workload during the packaging of the wooden frame of the aluminum profile of the rail car and nail accurately without error.

[0008] The technical solution of the present utility model is as follows: An upper cover pressing block is horizontally fixed at the top of the main body vertical plate. Several funnel-shaped upper cover nail inlet openings are opened on the upper cover pressing block. A calibration upper side plate gripper and a lower side plate gripper are respectively fixed at the middle side edges of the upper cover pressing block. Lower support plate feet are respectively fixed at the lower side edges of the upper cover pressing block. Funnel-shaped lower support plate nail inlet openings are opened on the lower support plate feet. The beneficial effects of the present utility model are as follows: It provides a brand-new method for accurately positioning nails, and it is applicable to the packaging of all current aluminum profile wooden frames of rail vehicles. By changing the previous method of nailing nails, a universal nail alignment device for the packaging of aluminum profile wooden frames of rail vehicles is designed and manufactured, greatly simplifying the difficulty of nailing nails for wooden frames, and can ensure that the side plates, upper cover plates, and lower support plates are tightly connected together, avoiding the phenomenon of the wooden frame swaying and bulging, comprehensively ensuring the stability and safety of product transportation, and avoiding the phenomenon of the profile surface being damaged by nails due to human negligence, resulting in the scrapping of profiles. It improves the working efficiency of workers in nailing wooden frames. Workers can directly nail nails during work, canceling the previous aiming step, ensuring that the area where the nails are driven is fixed and does not deviate. It avoids the phenomenon of secondary rework caused by human negligence, reduces the usage amount of nails, further improves labor efficiency, and enhances product quality.
