Description

CONSTRUCTIVE APPLICATION IN PACKAGING FOR PACKAGING OF ELECTRODES

The present utility model patent application refers to a "CONSTRUCTIVE ARRANGEMENT APPLIED IN PACKAGING FOR ELECTRICITY PACKAGING", which has been developed for the purpose of providing a package that allows an easy opening, and which allows its subsequent closure, guaranteeing the insulation of the electrodes preventing them from absorbing moisture, besides the ease in transportation since it is equipped with a handle.

State of the art

02 If proper storage and handling care is not taken, the coated electrodes may be damaged. Some or all of the coating may be damaged, especially in cases of electrode bending or collision. Whenever any change in the state of the electrode is observed, it should not be used in operations of responsibility.

03 The excess moisture in the coating of the electrodes (especially the basic ones), is in general, harmful to welding. It can lead to arc instability, formation of spatter and porosity mainly at the beginning of the cord and embrittlement and cracking by hydrogen.

04 The humidity level can be measured in laboratories as stipulated in AWS A5.5-81. It can also be practically estimated when the moisture content is high enough, in two different ways: Verification of the behavior of the electrode during welding. The wet electrodes generally generate an explosive sound and, when the humidity is excessive, there will be, at the start of the welding, water vapor from the electrode. In addition, interruption of welding with a wet electrode occurs, the coating tends to crack longitudinally. 05 Verification of the sound produced by the shock of two or more electrodes. Two wet electrodes on the surface generated a muffled, more serious sound than dry electrodes, which in turn produce a sharper, metallic sound.

006 Proper storage and transport of the electrodes are very important for the maintenance of product quality. The greater the technology used to increase the quality of the product applied in the welding, the greater the need for techniques in the storage and transportation of the product, since they are more sensitive to external conditions.

07 Electrodes that are not stored properly become wet, resulting in various weld defects, such as porosity in the weld bead, cracking along the cord, splashing, etc.

08 In the same way, if the transport and handling of the electrode packaging are not carried out in accordance with the manufacturer's instructions, the products can be damaged and will not be able to be used, causing their disposal and damage to the industry. Some products are so sensitive that improper handling of the packaging can cause total product loss.

09 Techniques for transporting, storing and stopping electrodes, wires and welding fluxes are developed according to the degree of complexity of the products. The companies that manufacture these products invest heavily in the research of packaging, transportation, storage and stoving techniques better so that their products have a longer shelf life.

10 The coated electrode is a consumable rod widely available in the market. Its consumption is fast, but its use does not require expensive equipment and high technology, which justifies its demand.

11 There are four types of coating for this class of electrode, namely: - Cellulosic coating: produced with organic material, especially the cellulose which, due to being burned during the welding process, generates a good volume of protective gases.

- Rutyl coating: it is formed by up to 50% rutile (TiO ₂ ).

- Basic coating: it presents high levels of fluorite and calcium carbonate, which produce a very deoxidized weld metal.

- Very high-performance coating: the coating is rutrile or basic, plus iron powder, which increases the rate of metal deposition.

12 Storage of electrodes and cans

13 The storage of coated electrodes is carried out in closed cans, but they are unusable when they are opened, not used to store the electrodes that have not been used, which should be placed immediately in greenhouses to avoid the humidity.

14 According to ESAB's recommendations regarding the stacking of coated electrode cans, pallets should be used as a base for the cans, with a maximum of three cans stacked vertically. When stored horizontally, they should be positioned with the label facing up, using the pallets as the base for the cans.

15 In the storage process, the effect of temperature and humidity can not be neglected, which is why more and more advanced methods are being developed for the storage of electrodes. According to established parameters for storage of OK coated electrodes, the cellulosic electrodes can not be exposed to relative humidity higher than 50% and the ambient temperature should be in the range 18-50 ° C. For other coated electrodes, the relative humidity may not exceed 50% and the ambient temperature should be above 18 ° C.

16 Transportation of packaging 17 Pallets are also used to transport the electrodes, as they avoid shocks and possible damage to the packages. Whenever the cans are stored, they should be in a position that preserves the arc tips as they are the most sensitive parts of the electrodes. Thus, the handles of the cans are down.

018 Due to the above mentioned problems caused by humidity, the electrodes should preferably be purchased in hermetically sealed containers and stored in controlled environments, so as to avoid damage and contact with the humidity of the air.

The patent MU 8501213-0 comprises the present utility model patent to a method for coating, packaging and transporting welding electrodes, which facilitates the handling and provides better protection against moisture in the use thereof, which consists in assembling quantities (1), with tip protection, forming a package (2), which are placed in suitable bags (3). These bags (3) have a handle (4), which surrounds the packages (2) with the small quantities of electrodes (1) previously vacuum-packed or not and sealed by melting the end, which are packed in four bags (3), in suitcases (5) containing two foldable parts with locking system (6), locking with sealing (7) or locking and carrying handle (8).

Coated electrodes, as described, is a wire with a surrounding mass, which after drying is packed until its consumption. Due to the drying of the electrode mass, it becomes hygroscopic, ie after drying the coating captures the humidity of the air, adding again the water that was withdrawn during drying. This process deteriorates the coating and severely damages the weldability since water is a poison to any weld. To protect the electrode rods, the whole world developed and used metal cans (cans) that became standard at 20 kg for this type of welding. The can an excellent container for packaging with moisture barrier, but it brings other serious problems as we see next.

- Difficulty in transportation. The can does not allow a comfortable transport to the user, notably for its weight of 20 kg of rods, without the possibility of handles or the like.

- Difficulty in storing. Because the electrode cans have been designed to be transported and stocked standing, the rods are consequently also standing, which causes damage to the coating of the same, in view of the friction between them:

- Difficulty opening. Until then, every electrode can was recaptured, requiring a tool to be opened.

- Difficulty after open. Every can after open exposes the rods to moisture, since it does not have the possibility of being closed again, facilitating the entry of moisture and making the electrode moist due to the hygroscopic factor of the same, already mentioned.

- Difficulty in safety. Like all cans, after opening it is created metallic burr allowing the cut and injury to which it handles the can without the proper equipment of individual security like gloves.

- Difficulty of use. The can after opened, and used all the material is no longer useful, becoming scrap and a problem for companies that use it due to its disposal as unserviceable material.

- Aesthetic difficulty. Every manufacturer uses the metallic packaging as a vehicle of sales and dissemination of their brand and the can, like all metal, kneads and scratches easily, giving a negative image to the product contained therein. On account of these and others in said mentioned drawbacks, the inventor has developed the "CONSTRUCTIVE ARRANGEMENT APPLIED IN PACKAGING FOR ELECTRICITY PACKAGING", comprising a substantially rectangular body provided on the upper face of a first recessed surface which projects a first shoulder forming a positive annular groove followed by a cavity forming a negative groove extending therefrom, is formed on the upper face by a second surface through a secondary shoulder that terminates in a flap, while its lower face projects a crimping channel provided with a locking element, said flap being provided descended from locking rods provided in its lower sections of locking teeth which describe a "V", the locking rods are inserted into the channels of the casing, wherein the locking teeth are accommodated under the retaining walls of the brackets breakable latches arranged in the outer flaps, which internally project a channel endowed where the flap is housed, while the locking element receives the coupling of the locking locking tooth disposed on the outer face of the male circumferential locking ring which is inserted into the crimping channel, the outer flaps of the housing holding through holes for engaging a carrying handle while its bottom has ribs, The cap is provided with a handle-like aperture element.

22 In order to obtain a perfect understanding of what had been developed, there are attached illustrative drawings to which will be made numerical references, where:

Figure 1 shows a perspective view of the closed package.

Figure 2 shows exploded perspective view of the package.

Figure 3 shows a perspective view of the cap.

DESCRIPTION OF THE PREFERRED EMBODIMENTS In view of the drawings and their details, it can be seen that the "CONSTRUCTION DEVICE USED IN PACKAGING FOR ELECTRICITY PACKAGING", characterized in that a main body (1) formed by a housing (2) and a cover (3) (4) of a first recessed surface (5) which projects a first shoulder (6) forming a positive annular groove (7), followed by a cavity (8) forming a negative groove (9) which (10) through a secondary shoulder (11) terminating in a flap (12), while its lower face (13) projects a crimping channel ( 14) provided with a locking element (15), said flap (12) being provided downwards from locking rods (16) provided in their lower sections (17) with locking teeth (18) depicting a "V", the rods (16) are inserted into the channels (19) of the in (2), wherein the locking teeth (18) are accommodated beneath the retaining walls (20) of the breakable catch holders (21) arranged in the outer flaps (22), which internally project a bottomed channel (23) where the flap 12 is housed while the latch member 15 receives the locking engagement tooth coupling 25 disposed on the outer contouring locking ring face 26 which is inserted into the channel (14), the outer flaps (22) of the housing (2) having through holes (28) for engaging a transporting handle (29), while its bottom (30) has ribs (31), the (3) provided with a handle-like opening element (32).

31 Based on the described and illustrated, we can verify that "CONSTRUCTIVE APPLICATION IN PACKAGING FOR PACKAGING OF ELECTRODES" has enormous advantages, since the packaging of the electrodes in polymer, ensures greater ease in the handling, because it has a handle and allows the comfortable transport of the product, better protection of the electrodes, possibility to open and close the package as many times as necessary without the use of instruments or tools and maintenance of the electrodes protected against moisture in its original packaging, besides not requiring equipment to pack the electrodes (recravadeira), simply fill the packaging with the electrodes and cap manually.

32 It is worth mentioning that the packaging still has ease in protection, since it is a plastic packaging of easy opening and closing does not create burrs like cans avoiding the need to use PPE for its handling, ease of visualization of the mark, because instead to use lithography for printing and with the typical problems of printing on metal, the packaging carries label shrinkable, finally ecologically correct where every packaging is manufactured with 100% recyclable material.
