Description

Technical Field

[0001] This utility model relates to the field of wire processing technology, specifically a novel automatic round wire flattening mechanism. Background Technology

[0002] Currently, the commonly used wire flattening operation in the industry is as follows: Round wire (copper-tin alloy) on a spool is fed out by a wire feeding motor, passing directly between two upper and lower rollers. By adjusting the adjusting screw at the top, the round wire (copper-tin alloy) is flattened into a flat resistance wire. Then, a rear mechanism collects and arranges the wire.

[0003] Existing flattening technology has the following problems:

[0004] 1. It is impossible to fix the round wire in place to ensure its accurate position for subsequent crimping operations;

[0005] 2. The lack of a dial indicator to display the roller pressure can easily cause bent or broken wires in the finished resistors, resulting in inconsistent quality.

[0006] 3. The temperature rise of the wire during the flattening process will affect the resistance wire group value.

[0007] Therefore, in view of the above situation, there is an urgent need to provide a new type of automatic round wire flattening mechanism to overcome the shortcomings in current practical applications. Summary of the Invention

[0008] The purpose of this invention is to provide a novel automatic round wire flattening mechanism, which aims to solve the problems mentioned in the background art.

[0009] This utility model is implemented as follows: an automatic round wire flattening mechanism, comprising:

[0010] Main framework;

[0011] A flattening mechanism, comprising rollers, two sets of which are rotatably mounted on the main frame, and gears are fixedly mounted on both sets of rollers. The two sets of gears mesh with each other. The two sets of rollers are also provided with reinforcing parts for pressing the round wire, and water passage holes are provided inside the two sets of rollers.

[0012] The power mechanism is used to drive the flattening mechanism. The power mechanism is set on the main frame, and the main frame is also equipped with a positioning detection mechanism.

[0013] As a further embodiment of this utility model, the flattening mechanism also includes a high-precision dial indicator and adjusting screws mounted on the main frame.

[0014] As a further embodiment of this invention, a rotary slip ring is also provided at the end of the roller.

[0015] As a further embodiment of this utility model: the reinforcing part includes a ring disposed on the surface of the roller.

[0016] As a further embodiment of this utility model, the ring is a tungsten carbide ring.

[0017] As a further embodiment of this utility model: the power mechanism includes:

[0018] The motor is fixedly installed at the bottom of the main frame, and synchronous pulleys are fixedly installed on the output shaft of the motor and on one of the sets of rollers;

[0019] And a timing belt, which is used to connect two sets of timing pulleys.

[0020] As a further aspect of this utility model, the motor is an asynchronous motor.

[0021] As a further embodiment of this utility model: the positioning detection mechanism includes:

[0022] An L-shaped plate is fixedly installed on the main frame, and the L-shaped plate is also provided with a guide wire nozzle and a switch bracket;

[0023] And proximity switches that are fixedly installed on switch brackets.

[0024] As a further embodiment of this utility model, the main frame is also provided with a safety protective cover for protecting the gears.

[0025] Compared with existing technologies, the advantages of this utility model are as follows: In use, the round wire (copper-tin alloy) is fed through an automatic wire feeding shaft, pulled above the contact switch, and passed through a guide nozzle to the middle of two rollers. Once the PLC controller receives the proximity switch signal and the round wire has passed the guide nozzle and its position is relatively stable, the asynchronous motor in the power mechanism starts, transmitting power to the lower rollers via a synchronous belt and pulley. Through gear transmission, the upper and lower rollers move synchronously, pressing the round wire into a flat shape. The heat generated during the rollers' movement is dissipated through a central water passage connected to a cooling water tank. The curved surface between the two rollers is made of tungsten steel, which is durable, has high hardness, and is heat-resistant. A high-precision dial indicator allows for accurate adjustment of the downward pressure. The proximity switch detects the presence or absence of wire. The transmission between the synchronous belt, pulley, and gears ensures stable power.

[0026] This invention effectively solves the pain points of the current process, ensures product stability, reduces manpower consumption, has a high degree of automation, saves materials, reduces waste generation, facilitates the maintenance and upkeep of the equipment, and provides safety protection for the power transmission components to ensure the safety of personnel operation.

[0050] The main frame is also provided with a safety cover 2 for including the gear 13.

[0051] In this embodiment of the invention, the automatic round wire flattening mechanism is further equipped with a PLC controller. During use, the round wire (copper-tin alloy) is fed through the automatic feed shaft, pulled above the contact switch 42, passes through the guide nozzle 41, and enters the space between the two rollers 15. The PLC controller receives the signal from the proximity switch 42 and the round wire passes through the guide nozzle 41 and its position stabilizes (e.g., ...). Figure 3 ), then the power mechanism 3 (such as Figure 4 The asynchronous motor in the circuit starts and transmits power to the lower roller 15 via the synchronous belt 32 and synchronous pulley 31. The gear 13 then drives the upper and lower rollers 15 to move synchronously, pressing the round wire into a flat shape.

[0052] In summary, the working principle of this utility model is as follows: Round wire (copper-tin alloy) is fed through an automatic wire feeding shaft, pulled above the contact switch 42, and passed through the guide nozzle 41 to the middle of the two rollers 15. Once the PLC controller receives the signal from the proximity switch 42 and the round wire passes the guide nozzle 41 and its position is relatively stable, the asynchronous motor in the power mechanism 3 starts, transmitting power to the lower roller 15 via the synchronous belt 32 and synchronous pulley 31. The gear 13 drives the upper and lower rollers 15 to move synchronously, pressing the round wire into a flat shape. The heat generated during the movement of the two rollers 15 is dissipated through the central water passage 151 connected to a cooling water tank. The curved surface of the two rollers 15 is made of tungsten steel, which is durable, has high hardness, and is heat-resistant. A high-precision dial indicator 11 allows for accurate adjustment of the pressure. The proximity switch 42 detects the presence or absence of wire. The transmission between the synchronous belt 32, synchronous pulley 31, and gear 13 ensures stable power.
