1 / 7 “ASSEMBLY LINE DEVICE FOR WEAR PLATES AND GUIDES WITH INSERTS / BARS Tungsten / Chocky Bar and other wear items on the wear plate. 001 This utility model patent application refers to a "ASSEMBLY LINE DEVICE FOR WEAR PLATES AND GUIDES WITH INSERTS / BARS OF "Tungsten / Chocky Bar and Other Wear Items on Wear Plate" aims to provide a device for correctly positioning the wear plate for securing tungsten inserts / chocky bars and other wear items in a safe manner, facilitating and speeding up the operation. State of the Art 002 The equipment used in operations in sectors such as mining, rail, steelmaking, sugar mills, and cement plants is subject to intense abrasive wear and impact on structures and wear plates. 003 Therefore, from crushing and transport to the unloading of solids, the equipment involved in the various stages of operations in these industrial sectors receives lining plates. 004 In various branches of the manufacturing industry, during the different stages of production processes, there is a need to handle parts and assemblies until the final product is formed. The transport and handling of such parts (components) at each stage depends on the type of process, the size of the components, as well as their physical characteristics, such as dimensions, geometry, weight, and fragility. 005 During the manufacturing of relatively large structural components such as wear plates, for example, it is necessary to periodically position the component at various stages of the process. Petition 870240049685, dated 12 / 06 / 2024, page 5 / 11 2 / 7 manufacturing to allow tools operated by professionals to work on the component. For example, it may be necessary to position a board in close proximity to a professionally controlled welding machine to allow for hole welding in order to enable a perfect fixation of tungsten inserts / bars / chocky bars and other wear items on the board. It is therefore essential that the component be positioned accurately and immobile in relation to the tool so that professionals can reliably perform tasks based on the particular component being manufactured. 006 The manufacture of wear plates requires careful and laborious work, as the installation and assembly of tungsten pads / bars / chocky bars and other wear items need to be carefully fixed so that they do not detach or lose their resistance properties due to excessive heat. Disadvantages of the current process: • The base plate needs to be moved initially to slowly position the wear items (tungsten inserts / bars / chocky bars) as they are positioned one by one. In this first stage, the wear items are fixed by spot welding on the edges of the wear plates. • Subsequently, the circuit boards, with all the wear items already in place, are taken to a soldering booth to be welded, thus requiring the boards to be moved again. • After the welding and cooling process, the wear plates are taken to the finishing stage, where the tack welds used at the beginning of the process to position the wear items are removed using grinders / sanders. Petition 870240049685, dated 12 / 06 / 2024, page 6 / 11 3 / 7 • Excessive wear on grinding discs and sanders. The weld points mentioned earlier are difficult to remove, which generates additional expenses for grinding discs (abrasive material), equipment (sander), and consequently excessive electricity consumption. • The operation of positioning wear items by spot welding (tacking) also leads to additional expenses for: man-hours and welding wire, significantly impacting the final cost of manufacturing the wear plates. • Excessive movement of the plates greatly increases the risk of accidents. Considering that in industry, load handling (p) is always the risk factor, eliminating or reducing it is always a factor to be considered to avoid / mitigate accidents. • In addition to the points mentioned above, we also end up with low productivity, which in turn leads to low competitiveness. Nowadays, time is a valuable commodity and the market / customers don't wait. Patent BR 102022 018897 1 refers to a guide jig (110B) comprising a guide jig body (112) and a fitting portion (300) provided over the guide jig body (112) and configured to be engaged in a partner fitting of the guide jig body (112) positioned relative to the partner fitting. The guide jig body (112) includes a guide through the hole (113, 114) provided as a through hole extending towards a relief portion of the fitting portion (300) engaged in the partner fitting and configured to guide the insertion direction of an insertion portion to be inserted into the through hole and moved towards the relief portion. The fitting portion (300) includes at least two protruding portions (301, 302). The at least two protruding portions are arranged in line in the insertion direction. A gap between adjacent salient portions (301, 302), among at least Petition 870240049685, dated 12 / 06 / 2024, p. 7 / 11 4 / 7 two protruding portions (301, 302), is defined to have a length corresponding to the thickness of the partner fitting. Patent BR 10 2019 005845 5 concerns equipment intended for the welding area, where its main purpose is to improve product quality, contribute to good ergonomics for operators, and, due to its versatility, facilitate the handling of this equipment during the main welding processes. It can be implemented in various industrial segments and in the learning area, highlighting industrial learning institutions and higher education institutions, as well as in companies that use welding in some of their manufacturing processes. It is basically constituted of a support body (1) which is made up of two structures made of metal tubes. The first is formed by a height-adjustable base (2), equipped with wheels (3) and a base for a welding machine (4).The second is formed by a movable base in vertical and horizontal tubes provided with slider tubes (5), fixing clamps (6 and 7), tool holder arm (8), support bar (9), manual tightening pin (10), spring-loaded tightening pin (11), wing nuts (12). The assembly of said support is done by coupling the first structure onto the second, being locked by means of the spring-loaded actuation pin (11) which adjusts the desired height. 009 The objective of the present application is directed towards the assembly of a table jig and methods for a welded sheet metal assembly line for use in industry, according to which workpieces on the table jig assembly can be connected with precision. 010 The objective of this application is a jig that positions tungsten carbide inserts / bars / chocky bars and other wear items in guides that prevent their displacement when the plate is positioned on it, with the aim of significantly increasing the production of plates and guides in the same way. Petition 870240049685, dated 12 / 06 / 2024, p. 8 / 11 5 / 7 work period. Production can increase by up to 150% in the same work period (one shift). 011 The objective of this application is a device that allows welding for the fixation of tungsten carbide inserts / chocky bars and other wear bar items through their external (lower / base) face, eliminating visible welds that damage the tungsten carbide inserts / chocky bars and other wear bar items and reduce their mechanical resistance, in addition to the rework required to remove the weld points used to fasten / tack and guide the tungsten carbide inserts / chocky bars and other wear items. 012 In this way we eliminate 4 assembly steps, which include: - align the tungsten brake pads / bars / chocky bars and other wear items "one by one manually"; - Tack solder the bars (tungsten inserts / bars / chocky bars); - Turn the sheets over (which weigh close to 50kg, causing extreme physical strain on our employees, and risk of trapping hands / fingers during this operation) and apply the joining weld to the oblong holes in the sheets; - Turn the plates over again, weighing approximately 50kg, to eliminate the spot welding done by grinding, used to align tungsten carbide inserts / bars / chocky bars and other wear items. 013 In order to obtain a perfect understanding of what has been developed, illustrative drawings are appended to which numerical references are made together with a detailed description that follows, where: Figure 1 shows a front perspective view of the plate. Figure 2 shows a rear perspective view of the plate. Figure 3 shows a cross-sectional view of the plate.
