Description

Technical Field

[0001] This utility model relates to a bending machine, and more particularly to a bending machine that can adjust the bending angle and curvature. Background Technology

[0002] Ordinary bending machines on the market use pneumatic power to drive mechanical bending, such as the one with publication number CN116581618A, titled "A Pin Bending Machine and Its Processing Method". The bending machines with this structure produce pins with fixed angles and curvatures, which cannot be well adapted to connectors of various specifications. How to create a bending machine that can adjust the bending angle and curvature is the technical problem we need to solve now. Utility Model Content

[0003] In view of the shortcomings of existing technology, this utility model provides a bending machine.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: a bending machine, characterized in that it includes a machine base, on which a first bending mechanism is provided to bend the pins of a connector by rotation, and a clamping plate for holding the connector is provided below the first bending mechanism. The clamping plate has a reciprocating motion path of front-back and up-down. When the pins are bent, the connector adjusts the bending angle of the pins by the front-back and up-down cooperation of the clamping plate.

[0005] The device includes a mounting plate for assembling clamps, a first fixed seat on the mounting plate, a first fixed plate on one side of the mounting plate, a first lead screw that engages with the first fixed seat on the first fixed plate, and a first drive mechanism that engages with the first lead screw on the first fixed plate. The mounting plate achieves up-and-down reciprocating motion through the cooperation of the first fixed seat, the first lead screw and the first drive mechanism.

[0006] The first fixed plate is provided with a first guide rail, and the mounting plate is provided with a first slider that cooperates with the first guide rail. The mounting plate and the first fixed seat achieve reciprocating motion through the cooperation of the first slider and the first guide rail.

[0007] The system includes a second fixed plate that is fixedly assembled with the first fixed plate. The first fixed plate and the second fixed plate are perpendicular to each other. The second fixed plate is provided with a second fixed seat. The machine base is provided with a second lead screw that cooperates with the second fixed seat. The machine base is also provided with a second drive mechanism that cooperates with the second lead screw. The second fixed plate achieves reciprocating motion back and forth through the cooperation of the second lead screw, the second fixed seat and the second drive mechanism.

[0008] The machine base is provided with a second guide rail, and a second slider that cooperates with the second guide rail is provided on the second fixed plate. The second fixed plate and the machine base achieve reciprocating motion through the cooperation of the second slider and the second guide rail.

[0009] The clamping plate is provided with a limiting groove for the connector to be inserted, and the mounting plate is provided with a stop plate to prevent the connector from moving. One side of the mounting plate is provided with a third driving mechanism that forces the clamping plate to reciprocate and cooperates with the stop plate. When the connector is inserted into the limiting groove, the connector is limited in the limiting groove through the cooperation of the third driving mechanism and the stop plate.

[0010] The limiting groove is provided with a push plate that forces the connector to move up and down reciprocally. The mounting plate is provided with a fourth drive mechanism that forces the push plate to move up and down reciprocally. The connector achieves up and down reciprocating movement in the limiting groove through the cooperation of the push plate and the fourth drive mechanism.

[0011] The machine platform is provided with a second bending mechanism on one side opposite to the first bending mechanism to bend the connector pins. The clamping plate realizes the mutual conversion between the first bending mechanism and the second bending mechanism through a back-and-forth reciprocating motion path.

[0012] The machine tool includes a cover for cooperating with the first bending mechanism and the second bending mechanism. The outside of the cover is equipped with a servo motor and a planetary reducer that cooperate with the first bending mechanism and the second bending mechanism. Both the first bending mechanism and the second bending mechanism are equipped with bending shafts that are rotatably connected to the cover. A plug is fixed on the bending shaft. The plug is equipped with a hole for a pin. The pin is inserted into the hole, and the bending operation is achieved by rotating the bending shaft.

[0013] The machine cover is equipped with a servo zero-position switch and a servo limit switch to limit the rotation of the bending shaft. The bending shaft is equipped with a sensing block that works in conjunction with the servo zero-position switch and the servo limit switch. The bending shaft switches the positions of the servo zero-position switch and the servo limit switch through the sensing block to limit the rotation.

[0014] The beneficial effects of this utility model are as follows: Based on the bending mechanism, this utility model adds front-to-back and up-and-down linear modules to the clamping plate of the connector, so that the connector can be bent in conjunction with the linear modules during the bending operation. When the connector pins are bent with their cooperation, the bending angle and curvature can be adjusted, which can accommodate more specifications of connectors. This utility model also has the characteristics of simple structure, convenient processing and easy assembly, and strong practicality. Attached Figure Description

Detailed Implementation

[0025] like Figures 1-9 As shown, a bending machine includes a machine base 100. The machine base 100 is equipped with a first bending mechanism 400 that bends the pins 210 of a connector 200 by rotation. Below the first bending mechanism 400 is a clamping plate 300 for holding the connector 200. The clamping plate 300 has a reciprocating motion path in front-back and up-down directions. When the pins 210 are bent, the connector 200 adjusts the bending angle of the pins 210 through the front-back and up-down movement of the clamping plate 300. In this application, the reciprocating motion path of the clamping plate 300 in front-back and up-down directions is added during the bending process. In this way, the bending angle and curvature of the pins 210 become adjustable. Different angles of the pins 210 can be obtained by setting a program on the machine base 100. The specific engineering process is detailed below.

[0026] The assembly includes a mounting plate 310 for assembling the clamping plate 300. The mounting plate 310 is provided with a first fixing seat 311. A first fixing plate 320 is provided on one side of the mounting plate 310. The first fixing plate 320 is provided with a first lead screw 321 that cooperates with the first fixing seat 311. The first fixing plate 320 is also provided with a first drive mechanism 322 that cooperates with the first lead screw 321. The mounting plate 310 achieves up-and-down reciprocating motion through the cooperation of the first fixing seat 311, the first lead screw 321 and the first drive mechanism 322. Preferably, a lead screw structure is adopted, which is structurally stable and has a long service life. The mounting plate 310 has an up-and-down movement path under the cooperation of the first lead screw 321 and the first drive mechanism 322, which means that the connector 200 also has an up-and-down movement path.

[0027] The first fixed plate 320 is provided with a first guide rail 323, and the mounting plate 310 is provided with a first slider 312 that cooperates with the first guide rail 323. The mounting plate 310 and the first fixed seat 311 achieve reciprocating motion through the cooperation of the first slider 312 and the first guide rail 323. The cooperation of the first guide rail 323 and the first slider 312 makes the up-and-down reciprocating motion of the mounting plate 310 more stable and reliable, and more practical.

[0028] The system includes a second fixing plate 330 fixedly assembled with the first fixing plate 320. The first fixing plate 320 and the second fixing plate 330 are perpendicular to each other. The second fixing plate 330 is provided with a second fixing seat 331. The machine base 100 is provided with a second lead screw 110 that cooperates with the second fixing seat 331. The machine base 100 is also provided with a second drive mechanism 120 that cooperates with the second lead screw 110. The second fixing plate 330 achieves back-and-forth reciprocating motion through the cooperation of the second lead screw 110, the second fixing seat 331 and the second drive mechanism 120. Preferably, a lead screw structure is adopted, which is structurally stable and has a long service life. The second fixing plate 330 has a back-and-forth movement path through the cooperation of the second lead screw 110 and the second drive mechanism 120, which means that the connector 200 also has a back-and-forth movement path. The cooperation of the second drive mechanism 120 and the second lead screw 110 can not only adjust the bending angle and curvature of the pin 210, but also move the clamping plate 300 back and forth to facilitate the insertion of the connector 200.

[0029] The machine base 100 is provided with a second guide rail 130, and the second fixed plate 330 is provided with a second slider 332 that cooperates with the second guide rail 130. The second fixed plate 330 and the machine base 100 achieve reciprocating motion through the cooperation of the second slider 332 and the second guide rail 130. The cooperation of the second guide rail 130 and the second slider 332 makes the forward and reciprocating motion of the second fixed plate 330 more stable and reliable, and more practical.

[0030] The clamping plate 300 is provided with a limiting groove 340 for the connector 200 to be inserted. The mounting plate 310 is provided with a stop plate 350 to prevent the connector 200 from moving. One side of the mounting plate 310 is provided with a third driving mechanism 360 that forces the clamping plate 300 to reciprocate and cooperates with the stop plate 350. When the connector 200 is inserted into the limiting groove 340, the connector 200 is limited in the limiting groove 340 through the cooperation of the third driving mechanism 360 and the stop plate 350. The third driving mechanism 360 adopts a cylinder device. When the third driving mechanism 360 pulls the clamping plate 300 backward, the connector 200 will push against the stop plate 350, thus completing the lateral clamping of the connector 200.

[0031] The limiting groove 340 is provided with a push plate 370 that forces the connector 200 to move up and down reciprocally. The mounting plate 310 is provided with a fourth drive mechanism 371 that forces the push plate 370 to move up and down reciprocally. The connector 200 achieves up and down reciprocating movement in the limiting groove 340 through the cooperation of the push plate 370 and the fourth drive mechanism 371. The fourth drive mechanism 371 adopts a cylinder device. After the third drive mechanism 360 completes the lateral clamping of the connector 200, the fourth drive mechanism 371 begins to adjust the vertical position of the connector 200.

[0032] The machine tool 100 is provided with a second bending mechanism 500 on one side opposite to the first bending mechanism 400, which bends the pins 210 of the connector 200. The clamping plate 300 realizes the mutual conversion between the first bending mechanism 400 and the second bending mechanism 500 through a back-and-forth reciprocating motion path. The purpose of setting two sets of bending mechanisms is to adapt to connectors 200 of different specifications. The spacing of the pins 210 on some connectors 200 is different, so the specifications of the insert blocks 440 on the first bending mechanism 400 and the second bending mechanism 500 are also different. This application already has a back-and-forth reciprocating motion path, so it is very convenient to cooperate with the first bending mechanism 400 and the second bending mechanism 500. In this way, it can easily adapt to several sets of connectors 200 of different specifications, which is highly practical.

[0033] The machine base 100 includes a cover 140 for cooperating with the first bending mechanism 400 and the second bending mechanism 500. The outside of the cover 140 is provided with a servo motor 410 and a planetary reducer 420 for cooperating with the first bending mechanism 400 and the second bending mechanism 500. Both the first bending mechanism 400 and the second bending mechanism 500 are provided with a bending shaft 430 that rotatably cooperates with the cover 140. The bending shaft 430 is rotatably connected to the cover 140. An insert block 440 is fixed on the bending shaft 430. The insert block 440 is provided with an insertion hole 441 for cooperating with the insert pin 210. The insert pin 210 is inserted into the insertion hole 441, and bending is achieved by rotating the bending shaft 430. The insertion hole 441 of the insert block 440 is inserted into the insert pin 210, and bending is achieved by rotating the bending shaft 430.

[0034] The housing 140 is equipped with a servo zero-position switch 141 and a servo limit switch 142 to limit the rotation of the bending shaft 430. The bending shaft 430 is equipped with a sensing block 431 that works in conjunction with the servo zero-position switch 141 and the servo limit switch 142. The bending shaft 430 switches the positions of the servo zero-position switch 141 and the servo limit switch 142 through the sensing block 431 to form a rotation limit. The addition of the servo limit switch 142 avoids over-bending of the pin 210 due to programming errors. The addition of the servo zero-position switch 141, in conjunction with the servo motor 410, enables the bending shaft 430 to have an initial zero position, increasing the rotational stability of the bending shaft 430. The servo zero-position switch 141 and the servo limit switch 142 are optical switches, which are relatively mature technologies on the market and will not be described in detail here. The added servo zero-position switch 141 and the servo limit switch 142 limit the total stroke of the bending shaft 430.

[0035] Workflow:

[0036] When bending is required, the second drive mechanism 120 pushes the clamping plate 300 outward from the machine tool 100, placing the connector 200 to be processed into the limiting groove 340 of the clamping plate 300. The third drive mechanism 360 pulls the clamping plate 300, causing the connector 200 to be abutted by the stop plate 350 and completed lateral clamping. Then, with the cooperation of the fourth drive mechanism 371, the connector 200 is moved to the correct vertical position, completely fixing the connector 200 in the limiting groove 340. The second drive mechanism 120 moves the clamping plate 300 towards the bending station. At this time, the bottom of the insertion block 440 of the first bending mechanism 400 faces the insertion pin 210. With the cooperation of the first drive mechanism 322, the clamping plate 300 rises to the bending station. The first bending mechanism 400 starts to rotate and bend the pin 210. At the same time, the first drive mechanism 322 and the second drive mechanism 120 work together to adjust the bending angle and curvature of the pin 210 by moving the connector 200 back and forth and up and down. Finally, the bending operation is completed. After the operation is completed, the second drive mechanism 120 causes the clamping plate 300 to exit the station, the first bending mechanism 400 resets, the second drive mechanism 120 moves the clamping plate 300 to the outside of the machine 100, the third drive mechanism 360 releases the connector 200, and the fourth drive mechanism 371 also begins to reset. The connector 200 can then be taken out from the limiting groove 340 and wait for the next round of bending operation.
