Description

Technical Field

[0001] The utility model relates to the technical field of terminal bending, in particular to a bending machine. Background Art

[0002] The terminal board is an electronic component used for electrical connection. The terminal board is used to facilitate wiring and is generally equipped with labels so that the connection between the device and the outside world can be clearly seen. During the production and processing of the terminal board, the PIN pins of the terminal board need to be bent through a converted bending mechanism so that they can meet the usage requirements.

[0003] The upper and lower forming molds of the bending molds currently used are mostly fixedly connected and installed, that is, the upper and lower forming molds basically only have the movement process of upper and lower mold closing, and there is no wedge block adjustment process. Due to processing errors and assembly errors, it is difficult to control the bending angle when the mold is bent. When the bending size is not in place, it will directly affect the size of the subsequent process. For this reason, we designed a bending machine to solve the above problems. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a bending machine which solves the problems raised in the above-mentioned background technology.

[0005] To achieve the above purpose, the utility model is implemented through the following technical solutions: a bending machine, including a cabinet and a terminal board, the cabinet is equipped with a control console, and a cabinet door is arranged on the outside of the cabinet, a fixed plate is fixedly installed on the inside of the cabinet, and two groups of conveying ports are symmetrically distributed on both sides of the cabinet, hydraulic equipment and guide rails are fixedly installed on the fixed plate, an upper mold is mounted below the driving shaft of the hydraulic equipment, a lower mold that can slide along the guide rail is mounted on the guide rail, and evenly distributed positioning blocks and guide sleeves are mounted on the lower mold, and a bending plate corresponding to the positioning blocks is connected to the bottom of the upper mold.

[0006] Furthermore, a material tray is installed under the cabinet, and the terminal board is coiled on the inner side of the material tray. The position of the material tray corresponds to the position of the output port on the cabinet. The terminal board to be processed is coiled on the material tray. When the material tray is working, it can rotate under the action of the servo motor and cooperate with the conveying port on the outside of the cabinet to input the terminal board into the lower mold in the cabinet.

[0007] Furthermore, the fixed plate is equipped with a feeding mechanism symmetrically distributed on both sides of the hydraulic equipment. The position of the feeding mechanism corresponds to the conveying port and the middle position of the upper mold. The feeding mechanism on the fixed plate can assist the input and output of the terminal board in the cabinet, move the terminal board in the input cabinet to the lower mold and the upper mold for bending processing, and output the terminal board after the processing is completed.

[0008] Furthermore, the bottom end of the bending plate is provided with evenly distributed bending grooves, and the bending grooves match the terminal board. The bending grooves at the bottom end of the bending plate can correspond to the PIN pins on the terminal board, thereby achieving extrusion and bending thereof.

[0009] Furthermore, a slideway matching the bending plate is provided in the guide sleeve, and a recess matching the bottom end of the guide sleeve is provided on the conveying positioning block. The slideway provided on the guide sleeve can limit and guide the movement of the bending plate to ensure the bending position of the bending plate. When the bending plate is pressed down, the terminal board can be bent in cooperation with the recess on the positioning block. The recesses on the four groups of positioning blocks correspond to the bending states of the terminal board at 45 degrees, 75 degrees, 90 degrees, and 90 degrees.

[0010] Furthermore, the control console and control cabinet are electrically connected to the material tray, feeding mechanism, and hydraulic equipment. The control console and control cabinet can cooperate to realize the automatic operation of various electrical equipment in the device, realize the coordination between the structures, and ensure the degree of automation of the bending machine.

[0011] The utility model provides a bending machine, which has the following beneficial effects:

[0012] The bending machine, through the coordinated use of the bending plate and the terminal plate as well as the positioning block and the bending groove, enables the bending machine to deliver the terminal plate to the interior of the lower mold through the coordinated action of the material tray and the feeding mechanism during operation. The upper mold drives the bending plate to move under the action of the hydraulic equipment, and cooperates with the positioning block to form a bending action. The bending angles of the four evenly arranged groups of bending plates and positioning blocks are different, and they are bent to a 90-degree PIN state by a step-by-step bending process. The 90-degree bending of a terminal plate adopts the first pre-bending of 45 degrees, the second pre-bending of 75 degrees, the third forming of 90 degrees, and the fourth trimming and adjustment of 90 degrees to ensure the bending effect of the bending machine.

[0020] See also Figures 1 to 4 The utility model provides a technical solution: a bending machine, including a cabinet 1 and a terminal board 14, a control console 2 is installed on the cabinet 1, and a cabinet door 3 is arranged on the outside of the cabinet 1, a material tray 5 is installed at the bottom of the cabinet 1, the terminal board 14 is coiled on the inner side of the material tray 5, and a servo motor for driving the material tray 5 to rotate is arranged at the bottom of the cabinet 1. The terminal board to be processed is coiled on the material tray 5, and the material tray 5 can rotate under the action of the servo motor when working. The position of the material tray 5 corresponds to the position of the output port on the cabinet 1, and cooperates with the conveying port on the outside of the cabinet 1 to input the terminal board into the lower mold 8 in the cabinet 1, so as to facilitate the continuous bending processing of the terminal board.

[0021] A fixed plate 7 is fixedly installed on the inner side of the cabinet 1, and two groups of conveying ports are symmetrically distributed on both sides of the cabinet 1. A hydraulic device 11 and a guide rail 6 are fixedly installed on the fixed plate 7. The fixed plate 7 is equipped with a feeding mechanism 10 symmetrically distributed on both sides of the hydraulic device 11. The feeding mechanism 10 on the fixed plate 7 can assist the input and output of the terminal board in the cabinet 1. The position of the feeding mechanism 10 corresponds to the conveying port and the middle position of the upper mold 9. The terminal board input into the cabinet 1 is moved to the lower mold 8 and the upper mold 9 for bending processing, and the terminal board is output after the processing is completed.

[0022] See also Figures 2 to 5 An upper mold 9 is mounted below the driving shaft of the hydraulic equipment 11, and a lower mold 8 that can slide along the guide rail 6 is mounted on the guide rail 6. The lower mold 8 is mounted with evenly distributed positioning blocks 15 and a guide sleeve 12. A bending plate 13 corresponding to the positioning blocks 15 is connected to the bottom of the upper mold 9. There are four groups of bending plates 13 and positioning blocks 15. The 90-degree bending of a terminal plate 14 adopts the first pre-bending of 45 degrees, the second pre-bending of 75 degrees, the third forming of 90 degrees, and the fourth trimming and adjustment of 90 degrees. The bottom end of the bending plate 13 is provided with evenly distributed bending grooves 16. The bending grooves 16 at the bottom end of the bending plate 13 can correspond to the PIN pins on the terminal plate 14, and the bending grooves 16 match the terminal plate 14, thereby realizing extrusion and bending thereof, and ensuring the bending effect of the terminal plate 14.

[0023] A slideway matching the bending plate 13 is provided in the guide sleeve 12. The slideway provided on the guide sleeve 12 can provide limit guide for the movement of the bending plate 13 to ensure the bending position of the bending plate 13. A recess matching the bottom end of the guide sleeve 12 is provided on the conveying positioning block 15. When the bending plate 13 is pressed down, the terminal plate 14 can be bent in cooperation with the recess on the positioning block 15. The four groups of recesses on the positioning blocks 15 correspond to the bending states of the terminal plate 14 at 45 degrees, 75 degrees, 90 degrees, and 90 degrees. The control console 2 and the control cabinet 4 are electrically connected to the material tray 5, the feeding mechanism 10, and the hydraulic equipment 11. The control console 2 and the control cabinet 4 can cooperate to realize the automatic operation of each electrical equipment in the device, realize the coordination between the structures, and ensure the degree of automation of the bending machine.

[0024] In summary, when the bending machine is in use, the terminal board to be processed is coiled on the material tray 5, and the operation console 2 controls the overall operation of the equipment. The material tray 5 rotates and cooperates with the conveying port on the outside of the cabinet 1 to input the terminal board into the lower mold 8 in the cabinet 1. After the terminal board is sent to the inside of the lower mold 8, it is above the positioning block 15. The positions of the lower mold 8 and the upper mold 9 correspond. The hydraulic equipment 11 works and drives the upper mold 9 to press down repeatedly through its driving shaft. The feeding mechanism 10 cooperates with the downward pressing action of the upper mold 9 to intermittently and evenly input the terminal board between the lower mold 8 and the upper mold 9. The mold 9 drives the bending plate 13 to move under the action of the hydraulic equipment 11, and cooperates with the positioning block 15 to form a bending action. The four evenly arranged groups of bending plates 13 and positioning blocks 15 have different bending angles, and are bent to a 90-degree PIN state using a step-by-step bending process. The 90-degree bending of a terminal board 14 uses a first pre-bending of 45 degrees, a second pre-bending of 75 degrees, a third forming of 90 degrees, and a fourth trimming and adjustment of 90 degrees. The bent terminal board is output from the conveying port on the other side of the cabinet 1, completing the working process of the entire bending machine.
