Embodiment 1

[0028] Embodiment one is basically as attached figure 1 and figure 2 shown, including the following steps:

[0029] S1, first set the porcelain sleeve 4 with serrated edges on the end of the cylindrical spike, make the serrated edge of the porcelain sleeve 4 face away from the outer side of the spike end, and the end surface of the spike is located in the porcelain sleeve 4, keep The distance between the end face of the thorn nail and the serrated end face of the porcelain sleeve 4 is 2-4mm, preferably 3mm in the first embodiment;

[0030] S2, then turn the side of the roller to be welded with the thorn to the top, place the thorn upright on the roller through the porcelain sleeve 4 and make the serrated edge of the porcelain sleeve 4 contact the roller;

[0031] S3, every time a thorn is placed, the welding head is moved downward to cover the thorn and the porcelain sleeve 4, the welding rod is inserted into the porcelain sleeve 4 from the sawtooth gap of the porcelain sle...

Embodiment 2

[0038] The difference from Embodiment 1 is that in step S1, two opposite arc-shaped grooves 11 are formed on the serrated side of the porcelain sleeve 4 that contacts the roller, and the arc-shaped grooves 11 are coaxially opened, and the porcelain sleeve 4 After being placed on the roller, the distance between the arc-shaped groove 11 and the roller is greater than the distance between the sawtooth groove 12 and the roller. When grinding the arc-shaped groove 11 on the porcelain sleeve 4, use a hand grinding wheel. The porcelain sleeve 4 grinds After exiting the arc groove 11, such as image 3 Shown; When allowing porcelain cover 4 to contact roller in step S2, allow the axes of two arc-shaped grooves 11 of porcelain cover 4 to be parallel with the central axis of roller; In step S4, electrode extends into porcelain by arc-shaped groove 11 Set of 4.

[0039] Because the surface of the roller is an arc surface, the serrated edge of the porcelain sleeve 4 is hard. When the tho...

Abstract

The invention relates to the field of cotton processing and making, in particular to a new process of barbed nail welding. The new process includes the steps that S1, a porcelain bushing with the picot edges first sleeves the end of a cylindrical barbed nail, the picot edges of the porcelain bushing face the outer sides, away from the end of the barbed nail, and the end face of the barbed nail islocated in the porcelain bushing; S2, the side face of the to-be-welded barbed nail of a roller is then rotated to the top, the barbed nail is vertically placed on the roller through the porcelain bushing, and the picot edges of the porcelain bushing are in contact with the roller; S3, a welding head is moved downwards and covers the barbed nail and the porcelain bushing, a welding rod is melted by the welding head through arc welding, the porcelain bushing is filled with the melted welding rod, and after the liquid melted by the welding head cools, preliminary welding of the barbed nail is completed; and S4, the welding head is removed, and the porcelain bushing is scraped to complete barbed nail welding on the roller. According to the new process of barbed nail welding, the barbed nail is welded to the surface of the roller, the welding efficiency is high, and after the barbed nail falls, the surface of the roller is smooth without pot holes; and when the barbed nail is re-welded, the barbed nail is simply sleeved with the porcelain bushing and placed on the surface of the roller for welding, and replacement operation is easy and convenient.

Description

technical field [0001] The invention relates to the field of cotton processing and production, in particular to a new nail welding process. Background technique [0002] Cotton gin and cleaning machine are products in cotton processing machinery. There are cleaning rollers installed on the cotton gin and cleaning machine, and a plurality of thorns are welded on the cleaning roller. The thorns transmit the cotton during the rotation of the cleaning roller. At present, the welding method of thorns on the cleaning roller is: open holes for welding on the steel plate of the cleaning roller, pass the thorns through the holes of the steel plate, and then use arc welding to weld the thorns on the back of the steel plate. on the barrel. [0003] However, in the above-mentioned thorn welding method, after the thorn falls, the thorn breaks away from the hole on the steel plate, and the roller is easy to allow the hole to accumulate dust during the work process, and the balance is bro...
