Description

Processing method of anti-collision square tube and product thereof

Technical Field

The invention relates to the field of containers, in particular to a method for processing an anti-collision square tube and a product thereof.

Background

The container is a tool capable of carrying packaged or unpackaged goods for transportation and is convenient to load, unload and carry by mechanical equipment. On the door body of container, generally install crashproof side pipe beside the locking lever, the container door end takes place unusual collision and makes the locking lever take place to warp or damage the phenomenon and lead to the container door to open or close the difficulty when avoiding container loading and unloading. The door body of the container is in a concave-convex shape due to the structural characteristics of the door body composition. The surface of the anti-collision square pipe needs to be processed into a yielding notch meeting the requirements of the surface structure characteristics of the door body, and the square pipe can be ensured to be welded on the surface of the door body in a matching manner.

At present, the processing technology of the anti-collision square tube abdicating notch in the industry mainly adopts a sawing machine to saw or a plasma cutting gun to cut the square tube abdicating notch, then the 90-degree bending plate with proper size and specification is jointed with the square tube notch position needing sealing for tailor welding, wherein the 90-degree bending plate firstly adopts a plate shearing machine to shear blanking or a punch blanking die to blank, and then is bent and molded. The existing processing technology has complex flow and low man-hour efficiency, wastes much time for positioning no matter in sawing or plasma cutting, and the cutting speed of the two cutting modes is slower, so a great deal of labor is consumed; the influence of welding technology level is high, the product quality is unstable due to the difference of welding technology level or processing size error, and the product is not beautiful enough after being formed.

Disclosure of Invention

The invention aims to provide a processing method of an anti-collision square tube and a product thereof, which simplify the processing flow, improve the processing efficiency and improve the strength and quality stability of the product.

In order to achieve the above purpose, the solution of the invention is:

a processing method of an anti-collision square tube comprises the following steps:

step 1, designing a corresponding upper die and a corresponding lower die according to the size parameters of the anti-collision square tube; the upper die is provided with a profiling knife edge, the profiling knife edge comprises cutting edges, the number of the cutting edges is the same as that of the abdicating notches of the anti-collision square tube, the height difference of the cutting edges is matched with that of the abdicating notches of the anti-collision square tube, the lower die is provided with a profiling placing groove, and the width of the profiling placing groove is matched with that of the anti-collision square tube;

step 2, assembling the upper die and the lower die on a profiling device;

and 3, placing the prototype square pipe into the profiling placing groove, operating the profiling equipment to press the upper die downwards, and making the upper surface of the prototype square pipe sunken to form a yielding notch.

In the step 1, the joint of the adjacent cutting edges is designed to be in circular arc transition.

In the step 1, the two side walls of the profiling placing groove are inclined to the bottom wall of the profiling placing groove, and the distance between the two side walls is gradually increased towards the opening direction along the bottom of the profiling placing groove.

The utility model provides an anticollision side pipe, is applied to the container, the upper surface of anticollision side pipe has a plurality of correspondences the notch of stepping down that the concave-convex structure on the door body surface of container set up, should step down the notch and be through the processing method die mould shaping of above-mentioned anticollision side pipe, the upper surface of the notch of stepping down has the heavy groove of stepping down for the notch shaping of stepping down.

After the technical scheme is adopted, the abdicating notch of the anti-collision square tube can be formed through one-step compression molding, so that the processing technology of the abdicating notch of the anti-collision square tube is simpler, the labor hour efficiency is greatly improved, and a large amount of labor and energy consumption cost can be saved; the workman only need accomplish the operation of location and die mould can, it is little influenced by technical level, the steady controllable of quality of product to the notch of stepping down is die mould shaping, does not destroy the intensity of crashproof side's pipe, and product structural strength is better, the shaping is standard pleasing to the eye.

Detailed Description

In order to further explain the technical solution of the present invention, the present invention is explained in detail by the following specific examples.

The invention relates to a processing method of an anti-collision square tube, which comprises the following steps:

step 1, designing a corresponding upper die 1 and a corresponding lower die 2 according to the size parameters of an anti-collision square tube 3; referring to fig. 1 and 2, the upper die 1 has a profiling blade 11, the profiling blade 11 includes blades 111 having the same number as the notches 31 of the square anti-collision pipe 3, the height difference of the blades 111 matches the height difference of the notches 31 of the square anti-collision pipe 3, the lower die 2 has a profiling placing groove 21, and the width of the profiling placing groove 21 matches the width of the square anti-collision pipe 3;

step 2, assembling the upper die 1 and the lower die 2 on a profiling device;

and 3, placing the prototype square pipe into a profiling placing groove 21, and operating the profiling equipment to press the upper die 1 downwards to form a yielding notch 31 on the upper surface of the prototype square pipe.

In the step 1, the joint of the adjacent blades 111 is designed to be in arc transition, so that the upper surface of the anti-collision square tube 3 is prevented from being crushed by the profiling blade 11.

In the step 1, the two side walls 211 of the profiled placing groove 21 are both inclined to the bottom wall 212, and the distance between the two side walls 211 gradually increases along the bottom of the profiled placing groove 21 toward the opening direction, so that the opening size of the upper end of the profiled placing groove 21 is larger than that of the lower end of the profiled placing groove, and the demoulding of the formed anti-collision square tube 3 is facilitated.

The method can be used for producing the anti-collision square tube shown in figures 3 to 7, and is mainly applied to containers. The upper surface of the square anti-collision pipe 3 is provided with a plurality of abdicating notches 31 corresponding to the concave-convex structure on the surface of the door body of the container, the abdicating notches 31 are formed by the above method in a compression mode, and the upper surface of the abdicating notches 31 is provided with sinking grooves 311 for abdicating the shaping of the abdicating notches 31.

By the method, the abdicating notch 31 of the anti-collision square tube 3 can be formed by one-step compression molding, so that the processing technology of the abdicating notch 31 of the anti-collision square tube 3 is simpler, the labor hour efficiency is greatly improved, and a large amount of labor and energy consumption cost can be saved; the workman only need accomplish the operation of location and die mould can, it is little influenced by technical level, the stable controllable of quality of product to the notch 31 of stepping down is die forming, does not destroy anticollision side's pipe 3 intensity, and product structural strength is better, the shaping is standard pleasing to the eye.
