Description

Technical Field

[0001] The present invention relates to the technical field of gear processing equipment, and in particular to a perforated mesh precision gear processing equipment and a processing method thereof. Background Art

[0002] Perforated mesh precision gears are gears made by punching holes of specific shapes and sizes on metal sheets and then precision machining them. This type of gear not only inherits the structural flexibility of perforated mesh, but also has high-precision geometric dimensions and excellent mechanical properties.

[0003] Perforated mesh precision gear processing equipment plays an important role in modern industrial production, but there are some technical bottlenecks, such as the inability to automatically discharge waste and the inability to adjust cooling according to the heat generated by the mold. These problems not only affect production efficiency, but may also have an adverse effect on product quality. If the waste cannot be discharged in time, it will accumulate inside the equipment, resulting in frequent interruptions of the production line, requiring cleaning and maintenance. The accumulation of waste will increase the wear of the equipment, shorten the service life of the equipment, and increase maintenance costs. The accumulation of waste may cause equipment failures and even cause safety accidents, threatening the safety of operators; under long-term high-intensity work, the mold will generate a lot of heat. If the heat cannot be dissipated in time, the mold temperature will rise, affecting the accuracy and surface quality of the gear. High temperature will cause thermal expansion of metal materials, which will in turn affect the dimensional accuracy and shape stability of the gear. Without an effective cooling system, the temperature of each part of the mold is inconsistent, which will lead to uneven stress distribution inside the gear, affecting the mechanical properties of the gear. Due to the lack of automatic waste discharge and temperature control systems, the equipment requires more energy to maintain production, which increases energy consumption; Therefore, we propose a perforated mesh precision gear processing equipment and its processing method to solve this problem.

[0023] The present invention also provides a method for processing a punching mesh precision gear, comprising the following steps:

[0024] S1: Place the blank plate on the top of the processing table, start the cylinder to drive the mounting shell and the conveying wheel to move horizontally, so that the conveying wheel abuts against the outer side of the blank plate, start the rotary motor to drive the conveying wheel to rotate, thereby realizing the conveying positioning of the plate;

[0025] S2: Start the hydraulic cylinder to drive the ear plate and the upper mold to move downward, and implement the punching processing of the plate with the cooperation of the mandrel and the lower mold, so that the gear-shaped finished product falls into the receiving barrel along the mandrel, and the cylindrical waste formed by punching is lifted up by the mandrel and magnetically attracted by the permanent magnet. At the same time, the ear plate drives the linkage plate and the second connecting column to move downward, and the second connecting column drives the linkage frame to rotate clockwise through the cooperation with the second connecting hole. The linkage frame drives the vertical plate and the piston plate to move upward through the cooperation with the first connecting hole and the first connecting column, so that negative pressure is formed below the piston plate, and the cooling water is sucked into the cooling box from the water inlet pipe;

[0026] S3: Start the hydraulic cylinder to drive the ear plate and the lower mold to move upward. When the rotating frame contacts the baffle, the rotating frame starts to rotate and drives the square plate to move upward relative to the upper mold through the sleeve plate, thereby transporting the cylindrical punching waste upward. After the transmission gear contacts and starts to mesh with the transmission rack, the rotating arm rotates with the transmission gear and drives the permanent magnet and the cylindrical waste to perform circular motion. When the cylindrical waste contacts the guide groove, the cylindrical waste is blocked, and the permanent magnet continues to perform circular motion, and the magnetic attraction with the cylindrical waste is weakened. The cylindrical waste falls into the collection frame under the action of gravity and the guidance of the guide groove to achieve waste collection. During the upward movement of the ear plate, the piston plate is driven downward by the linkage plate and the linkage frame, thereby pushing the cooling water in the cooling box into the outlet pipe, and introducing it into the cooling channel through the inlet pipe to achieve cooling of the upper mold. After that, the cooling water is discharged through the outlet pipe and the drain pipe;

[0027] S4: The temperature inside the upper mold is monitored by a temperature sensor, and the detection result is transmitted to the controller. When the temperature sensor senses that the temperature of the upper mold has increased, the controller controls the output end of the electric push rod to extend, thereby driving the adjustment frame and the mounting shaft to move to the right, thereby increasing the distance between the mounting shaft and the first connecting column, so that the piston plate moves up and down with a larger amplitude when the linkage plate moves the same distance, thereby being able to extract and push more cooling water to cool the upper mold, thereby preventing its temperature from increasing during the punching process and affecting the processing performance.

[0028] Compared with the prior art, the present invention provides a perforated mesh precision gear processing device and a processing method thereof, which have the following beneficial effects:

[0029] (1) Through the provided conveying mechanism and driving mechanism, the automatic feeding and punching processing of the gear can be realized under the cooperation of the fixed frame, hydraulic cylinder, ear plate, cylinder, mounting shell, rotating motor, conveying wheel, upper mold, lower mold and mandrel, thereby improving the processing efficiency;

[0030] (2) Through the waste discharge mechanism, the waste generated by punching can be automatically transported out by the cooperation of the vertical plate, fixed plate, rotating frame, sleeve plate, square plate, connecting shaft, rotating arm, permanent magnet, transmission gear, transmission rack, U-shaped plate and baffle, so as to avoid the accumulation of waste and affect normal processing;

[0031] (3) Through the cooling mechanism, the cooling box, the water outlet pipe, the water inlet pipe, the second one-way valve, the first one-way valve, the first connecting column, the piston plate, the linkage plate, the second connecting column, the linkage frame, the first connecting hole, the second connecting hole, the mounting shaft, the adjustment frame, and the guide frame can be used to cool the mold by punching power to slow down the temperature rise of the mold;

[0032] (3) The temperature sensor can be used to monitor the temperature of the mold, and the controller and electric push rod can be used to adjust the cooling water flow rate according to the temperature of the mold, thereby adjusting the cooling rate to avoid continuous heating of the mold during high-intensity operation.

[0033] The present invention is reasonably designed. Through the waste discharge mechanism, the gear punching waste can be automatically discharged during the processing process to ensure the continuous and stable operation of the punching work. Through the cooling mechanism, the punching power can be used to cool the mold, and the cooling effect can be further improved after the mold is heated, so as to facilitate high-precision punching work.

[0067] The present invention also provides a method for processing a punching mesh precision gear, comprising the following steps:

[0068] S1: Place the blank plate on the top of the processing table 1, start the cylinder 201 to drive the mounting shell 202 and the conveying wheel 204 to move horizontally, so that the conveying wheel 204 abuts against the outer side of the blank plate, start the rotating motor 203 to drive the conveying wheel 204 to rotate, thereby realizing the conveying and positioning of the plate;

[0069] S2: Start the hydraulic cylinder 103 to drive the ear plate 104 and the upper mold 11 to move downward, and implement the punching processing of the plate with the cooperation of the core shaft 13 and the lower mold 12, so that the gear-shaped finished product falls into the receiving barrel 5 along the core shaft 13, and the cylindrical waste formed by the punching is lifted up by the core shaft 13, and is magnetically attracted by the permanent magnet 408. At the same time, the ear plate 104 drives the linkage plate 7 and the second connecting column 701 to move downward, and the second connecting column 701 drives the linkage frame 8 to rotate clockwise through the cooperation with the second connecting hole 802. The linkage frame 8 drives the vertical plate 307 and the piston plate 306 to move upward through the cooperation of the first connecting hole 801 and the first connecting column 305, so that negative pressure is formed below the piston plate 306, and the cooling water is sucked into the cooling box 3 from the water inlet pipe 302;

[0070] S3: Start the hydraulic cylinder 103 to drive the ear plate 104 and the lower mold 12 to move upward. When the rotating frame 403 contacts the baffle 412, the rotating frame 403 starts to rotate and drives the square plate 405 to move upward relative to the upper mold 11 through the sleeve plate 404, thereby transporting the cylindrical punching waste upward. After the transmission gear 409 contacts and starts to mesh with the transmission rack 410, the rotating arm 407 rotates with the transmission gear 409, and drives the permanent magnet 408 and the cylindrical waste to perform a circular motion. When the cylindrical waste contacts the guide groove 9, the cylindrical waste The permanent magnet 408 is blocked, and the permanent magnet 408 continues to move in a circular motion, and the magnetic attraction between the permanent magnet 408 and the cylindrical waste is weakened. The cylindrical waste falls to the collection frame 14 under the action of gravity and the guidance of the guide groove 9, so that the waste is collected. During the upward movement of the ear plate 104, the piston plate 306 is driven to move downward through the linkage plate 7 and the linkage frame 8, so that the cooling water in the cooling box 3 is pushed into the water outlet pipe 301, and is introduced into the cooling channel through the introduction pipe 1101, so as to realize the cooling of the upper mold 11, and then the cooling water is discharged through the outlet pipe 1102 and the drain pipe 1103;

[0071] S4: The temperature inside the upper mold 11 is monitored by the temperature sensor 15, and the monitoring result is transmitted to the controller 10. When the temperature sensor 15 senses that the temperature of the upper mold 11 increases, the controller 10 controls the output end of the electric push rod 805 to extend, thereby driving the adjustment frame 804 and the installation shaft 803 to move to the right, thereby increasing the distance between the installation shaft 803 and the first connecting column 305, so that the linkage plate 7 moves the same distance and the lower piston plate 306 moves up and down with a larger amplitude, so that more cooling water can be extracted and pushed to achieve cooling of the upper mold 11, thereby preventing its temperature from increasing during the punching process and affecting the processing performance.

9. A method for processing precision gears of punching mesh, characterized in that: The following steps are involved: S1: placing a blank plate on the top of a processing table (1), starting the cylinder (201) to drive the mounting shell (202) and the conveying wheel (204) to move horizontally, so that the conveying wheel (204) abuts against the outer side of the blank plate, and starting the rotating motor (203) to drive the conveying wheel (204) to rotate, thereby realizing the conveying and positioning of the plate; S2: Start the hydraulic cylinder (103) to drive the ear plate (104) and the upper mold (11) to move downward, and implement the punching processing of the plate with the cooperation of the core shaft (13) and the lower mold (12), so that the gear-shaped finished product falls into the receiving barrel (5) along the core shaft (13), and the cylindrical waste formed by punching is lifted up by the core shaft (13), and is magnetically attracted by the permanent magnet (408). At the same time, the ear plate (104) drives the linkage plate (7) and the second connecting column (701) to move downward, and the second connecting column (701) drives the linkage frame (8) to rotate clockwise through the cooperation with the second connecting hole (802). The linkage frame (8) drives the vertical plate (307) and the piston plate (306) to move upward through the cooperation with the first connecting hole (801) and the first connecting column (305), so that negative pressure is formed below the piston plate (306), and cooling water is sucked into the cooling box (3) from the water inlet pipe (302); S3: Start the hydraulic cylinder (103) to drive the ear plate (104) and the lower mold (12) to move upward. When the rotating frame (403) contacts the baffle (412), the rotating frame (403) starts to rotate and drives the square plate (405) to move upward relative to the upper mold (11) through the sleeve plate (404), thereby transporting the cylindrical punching waste upward. After the transmission gear (409) contacts and starts to mesh with the transmission rack (410), the rotating arm (407) rotates together with the transmission gear (409) and drives the permanent magnet (408) and the cylindrical waste to perform a circular motion. When the cylindrical waste contacts the guide groove (9), the cylindrical waste The waste is blocked, the permanent magnet (408) continues to move in a circular motion, and the magnetic attraction between the permanent magnet (408) and the cylindrical waste is weakened. The cylindrical waste falls into the collection frame (14) under the action of gravity and the guidance of the guide groove (9), thereby realizing waste collection. During the upward movement of the ear plate (104), the piston plate (306) is driven to move downward through the linkage plate (7) and the linkage frame (8), thereby pushing the cooling water in the cooling box (3) into the water outlet pipe (301) and introducing it into the cooling channel through the introduction pipe (1101), thereby realizing cooling of the upper mold (11). After that, the cooling water is discharged through the outlet pipe (1102) and the drain pipe (1103); S4: The temperature inside the upper mold (11) is monitored by the temperature sensor (15), and the monitoring result is transmitted to the controller (10). When the temperature sensor (15) senses that the temperature of the upper mold (11) has increased, the controller (10) controls the output end of the electric push rod (805) to extend, thereby driving the adjustment frame (804) and the installation shaft (803) to move to the right, thereby increasing the distance between the installation shaft (803) and the first connecting column (305), so that the linkage plate (7) moves the same distance and the lower piston plate (306) moves up and down with a larger amplitude, thereby being able to extract and push more cooling water to achieve cooling of the upper mold (11), thereby preventing its temperature from increasing during the punching process and affecting the processing performance.
