Wire bending machine with electromechanical bending technique

Abstract

The wire rack bending machine with electromechanical bending technique is in the technical field of industrial wire and metal wire bending machines and devices. The technical problem is the lack of a dedicated bending machine for bending wire racks of agricultural equipment, which requires expensive and general bending machines, which reduces production runs and increases production costs. The basis of the proposed solution is to build a device with an electric drive and completely mechanical functions, which is specifically designed to produce wire rope from cut wires placed in the device chamber, using mechanical mechanisms to bend the wires in a high-volume sequence, and then remove the resulting wire rope from the device's production cycle by a wire feeder. This device is used for bending wire ropes with a high-volume sequence in the agricultural machinery spare parts manufacturing industry.

Description

Description of the invention Title of the invention Wire rack bending machine with electromechanical bending technique Technical background of the relevant invention The industrially presented bending machine with electromechanical operation enables the industrial bending of high-volume wire racks, thus falling within the technical field of industrial wire and wire bending machines. Technical problem and stating the objectives of the invention A solar rake is a mechanical agricultural tool used to collect, turn, and stack forage (hay, straw, dry grass). The solar rake wires are the main and consumable components of this agricultural tool, which are in direct contact with the forage and the ground surface during operation and gradually wear and fatigue. The useful life of these wires depends on the operating conditions, type of soil, device adjustment, and quality of construction, but they usually need to be replaced after one to three growing seasons. Wear or deformation of the wires reduces the quality of forage collection, and their timely replacement is essential to maintain the proper functioning of the rake. Machines used for industrial bending include the following problems: Lack of a dedicated device for bending rake wires: The equipment available on the market is mainly general wire bending devices designed to produce industrial wires with standard shapes and cannot optimally bend spring wires with the shape, diameter, and angles required for agricultural rakes. Incompatibility with high-volume production needs: Commercial wire bending machines may be capable of low-volume production or for limited shapes, but they are not optimized for high-volume production with the appropriate accuracy, speed, and repeatability of reed wires (including a variety of diameters, lengths, and spring shapes). Cost and manpower problem: Using general machines for this task increases costs, mold change times, and requires a lot of manual adjustment, which is not cost-effective in industrial wire rack production. Purpose of the invention: Design and manufacture a dedicated electromechanical rack wire bending machine that can bend rack wires of different shapes and specifications with high accuracy, at the appropriate speed, and for industrial production, without the need for complex adjustments or excessive human intervention. A description of the state of the prior art and the history of developments related to the claimed invention. In recent years, the agricultural industry, and especially the forage harvesting and gathering sector, has required tools with high efficiency, good durability and industrial production capability. One of the key components of these tools is the solar rake wires, which act as the forage collecting part and gradually wear out and deform. Despite the importance of this part, the production and bending of rake wires is mainly done manually or semi-industrially, and there are no standard machines on the market that can bend spring wires with the shape, diameter and characteristics required by the rake in high volumes. In contrast, in the field of wire and wire bending, numerous patents have been registered, including general wire bending machines, programmable machines, and robotic equipment for bending industrial wires and wires. These machines, although useful in the production of precision industrial wires, are not suitable for bending agricultural rake wires with their special spring properties and unique shapes. This technical gap has provided an incentive to design and develop a dedicated electromechanical device for bending rake wires and their industrial production. 1.

This method allows the wire to be bent into specific shapes with high precision and without human intervention. 7. Wire bending machine, registration number: EP 0079587A1 Abstract: This invention relates to a wire bending machine that has a set of adjustable tools to create different bends depending on the diameter of the wire. The machine is designed in such a way that the bending tool and the cutting blade are alternately adjustable and can be used to produce precise bends in wires of different diameters. Providing a solution to an existing technical problem along with an accurate, sufficient, and integrated description of the invention The wire rack bending machine consists of several main parts, as follows: Central chassis: The chassis (1) of the device consists of metal cans of different sizes that are welded together, the upper part of which includes a wire storage compartment (75), and all components and mechanisms of the device are installed on this chassis (1). Wire rack feeding mechanism: The rake wires (77) are placed inside the wire storage chamber (75). These wires are sequentially fed through the slot (78) installed on the grooved roll (84) on the rotating shaft of the wire storage chamber (83). With each rotation, the wire is dropped onto the wire aligning and moving piece (48). The driving force of this mechanism is provided by gears (85,89), bearings (87), and chains (86) that lead to the central shaft (17). In the operation of dropping the wire rack (77) onto the wire alignment and moving piece (48), the rotation of the guide shaft (83) which is connected to the bearings (73, 82) on both sides and receives its driving force from the chain (50) and the gear (49, 72) connected to the central shaft is helpful. Rack wire sorting and transfer mechanism: The wire alignment and moving piece (48) simultaneously moves up, down, right and left within a limited range, which is operated by the rotation of the crank (46, 47) inside the bearing (44, 45) with the force resulting from the rotation of the gear (41, 43) and the chain (42), and its driving force is received by the gear (40, 38) and the chain (39) from the central shaft (17). Two guide toothed corners (79,80) support the wire alignment and moving piece (48) on both sides, and by moving the crank (46,47) 360 degrees, the aligned rake wires are moved one step forward, each time one rake wire (77) falls into the grooved piece of the longitudinal wire transfer (71). Horizontal movement and wire rack transfer mechanism for bending: The longitudinal wire transfer grooved piece (71) has two guide rails (81) on one side, and the longitudinal wire transfer grooved piece (70) connected to the chain (64) enters the groove of the two guide rails (81) as the chain moves, and then the longitudinal wire transfer grooved piece (71) moves the wire rack (77) located inside it forward longitudinally, which is then placed on the guide grooved piece (32). To adjust the timing of a chain (64) by rotating it, its length is important, which is why a chain tightening mechanism is provided using a roller (66), spring (67), and chain length adjustment rail (65) so that in addition to preventing chain vibration, the length of the chain (64) can also be controlled. The chain (64) performs its rotational motion by two gears (62,68) connected to two bearings (63,69) mounted on the chassis of the device (1), which provides its driving force through gears (59,61), chain (60), and shaft (57) rotating within the bearing (58). The source of this mechanical driving force then leads to the gearbox (5) and the electric motor (4) through the gear wheel (56), chain (55), large sun gear (54), shaft (53) driven inside the bearing, 90-degree gear (52,51), central shaft (17), 90-degree gear (18,14), shaft (13) driven inside two bearings (15,12), gear wheels (11,6) and chain (7). Wire rack bending mechanism: The rake wire (77) transferred onto the grooved guide piece (32) is bent by two large rollers (33,34) and two small rollers (22,23), and the necessary driving force is provided by the rotational force from the billet (21), shaft (20), secondary bracket (19), primary bracket (18), disc (10), and shaft (8) rotating within the bearing (9), gearbox (5), and electric motor (4). After bending the wire rack (3), the operation of ejecting the bent wire rack (3) from the bending cycle is performed by the movement of the wire feeder (31) which has a limited reciprocating motion on the wire feeder rail (30). This limited reciprocating motion is performed by the bracket (29), the crank (26, 28), the bearing (27), the gear (25, 88) and the chain (24) leading to the central shaft (17). Bending count counter mechanism: The mechanical counter (36) used to count the number of output bent wires is mounted on the upper part of the chassis (1) and is connected to the extension placed on the secondary bracket (19) by a string (27). With the limited rotational movement of this piece, the string is pulled and one number is added to the number of counts of the mechanical counter (36).
