Description

Technical Field

[0001] This utility model relates to the technical field of spring finger processing equipment, specifically a spring finger bending forming mold. Background Technology

[0002] With the rapid development of power equipment and precision electronic components toward miniaturization and high reliability, the spring contact finger, as a key conductive contact component, is affected by the accuracy and consistency of its bending forming, which directly affects the current carrying stability and mechanical life of the equipment. People usually use spring contact finger bending forming molds to bend the spring contact finger.

[0003] The existing spring contact bending forming mold places the straight spring contact from the production area into the spring contact bending forming mold, fixes one end of the spring contact, and then operates the traction component to pull the other end of the spring contact to move, so that the spring contact is bent into the required shape.

[0004] Existing spring contact finger bending forming dies require fixing the spring contact finger first, and then operating the traction component to bend the spring contact finger. The operation process needs to be carried out in steps, which is cumbersome and results in low bending forming efficiency of the spring contact finger. Therefore, we propose a spring contact finger bending forming die. Utility Model Content

[0005] The technical problem this invention aims to solve is to overcome existing defects and provide a spring contact finger bending forming mold. Through a bending mechanism, the fixed mold moves along with the fixed block during the fitting process of the moving mold, thereby squeezing and clamping the end of the spring contact finger with a clamping plate. Then, under the action of the fixing pin and the rotating shaft, turntables one and two rotate, thereby pulling the spring contact finger and moving it into the forming cavity. The bending operation of the spring contact finger is completed in one step during the closing process of the fixed mold and the moving mold. The operation is simple, and the bending forming efficiency of the spring contact finger is high, effectively solving the problems in the background art.

The upper side of the inner wall of the clearance groove is fixedly connected to the fixed pin. The outer surface of the rotating shaft is provided with a track groove. The fixed pin is slidably connected to the track groove. Through the bending mechanism, the fixed mold drives the fixed block to move during the process of the moving mold fitting together, thereby squeezing the clamping plate to clamp and fix the end of the spring contact finger. Then, under the action of the fixed pin and the rotating shaft, the turntable 1 and the turntable 2 are driven to rotate, thereby pulling the spring contact finger and moving it into the forming cavity. The bending operation of the spring contact finger is completed in one step during the closing process of the fixed mold and the moving mold. The operation process is simple and the bending forming efficiency of the spring contact finger is high.

[0008] Furthermore, the bending mechanism also includes a second turntable, a clamping plate, and a third spring. The second turntable is rotatably connected to the upper surface of the lower forming seat. An installation groove is provided inside the second turntable, and clamping plates symmetrically distributed on the left and right sides are slidably connected in the installation groove. A third spring is fixedly connected between the two clamping plates to clamp the spring contact finger.

[0009] Furthermore, the bending mechanism also includes fixing blocks, which are all fixedly connected to the lower surface of the turntable to press and clamp the plate.

[0010] Furthermore, the upper surface of the fixed mold is fixedly connected with evenly distributed positioning pins, and the interior of the moving mold is provided with evenly distributed positioning holes.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4This embodiment provides a technical solution: a spring finger bending forming mold, including a base 1, a fixed mold 2 fixedly connected to the upper surface of the base 1, a lower forming seat 3 fixedly connected to the upper surface of the fixed mold 2, a movable mold 4 provided on the upper side of the fixed mold 2, an adjustable upper forming seat 5 provided on the lower surface of the movable mold 4, and placement cavities 9 and forming cavities 10 respectively on the upper surface of the lower forming seat 3 and the lower surface of the upper forming seat 5. An unbent spring finger is placed in the placement cavity 9 on the upper surface of the lower forming seat 3. The placement cavity 9 and the forming cavity 10, located on the same horizontal plane, are connected. Evenly distributed positioning pins 6 are fixedly connected to the upper surface of the fixed mold 2. Evenly distributed positioning holes 7 are provided inside the movable mold 4. The positioning pins 6 are all inserted into vertically adjacent positioning holes 7. The positioning pins 6 are inserted into the positioning holes 7, and the movable mold 4 is pushed downwards, causing the movable mold 4 to move downwards. A sliding connection is provided inside the movable mold 4. The sliding columns 11 are symmetrically distributed front and back. The lower surfaces of both sliding columns 11 are fixedly connected to the upper surface of the upper forming seat 5. Spring 12 is fixedly connected between the upper surface of the sliding column 11 and the inner wall of the moving mold 4. The sliding column 11 moves downward, which drives the upper forming seat 5 to move downward. The moving mold 4 continues to move downward, and the sliding column 11 moves upward relative to the moving mold 4. The spring 12 contracts. The pressure block 13 is slidably connected inside the upper forming seat 5. Spring 2 14 is fixedly connected between the lower surface of the outer edge of the pressure block 13 and the inner wall of the upper forming seat 5. Spring 2 14 is sleeved on the outer surface of the pressure block 13. The moving mold 4 presses down on the protrusions on the left and right sides of the upper surface of the pressure block 13. Spring 2 14 contracts. The pressure block 13 moves downward and presses the spring finger located inside the forming cavity 10, thereby giving the spring finger vertical pressure and reducing the rebound stress inside the spring finger. It also includes a bending mechanism 8.

[0023] Bending mechanism 8: It includes a rotating shaft 81, a fixing pin 82, and a first turntable 83. The first turntable 83 is rotatably connected to the lower surface of the upper forming seat 5. The rotating shaft 81 is fixedly connected to the center of the upper surface of the first turntable 83. The upper end of the rotating shaft 81 is rotatably connected to a clearance groove inside the moving mold 4. The fixing pin 82 is fixedly connected to the upper side of the inner wall of the clearance groove. A track groove is opened on the outer surface of the rotating shaft 81, and the fixing pin 82 is slidably connected to the track groove. The bending mechanism 8 also includes a second turntable 85, a clamping plate 86, and a third spring 87. Turntable 2 85 is rotatably connected to the upper surface of the lower forming seat 3. An installation groove is provided inside turntable 2 85, and clamping plates 86 symmetrically distributed on the left and right sides are slidably connected within the installation groove. A spring 3 87 is fixedly connected between the two clamping plates 86. The bending mechanism 8 also includes fixing blocks 84, all of which are fixedly connected to the lower surface of turntable 1 83, so that the right end of the spring contact finger is located between the two clamping plates 86. When turntable 1 83 moves downward, the fixing blocks 84 move downward. When the lower surface of the upper forming seat 5 is perpendicular to the lower forming seat 3... When the upper surfaces are in contact, the fixing block 84 is inserted into the mounting groove. The lower end of the fixing block 84 presses against the inclined surface on the rear side of the clamping plate 86, causing the two clamping plates 87 to move towards each other. The spring 87 contracts, and the two clamping plates 87 clamp the right end of the spring contact finger. The rotating shaft 81 moves upward in the clearance groove, causing the fixing pin 82 to move in the vertical groove on the upper side of the track groove (both the upper and lower ends of the track groove are vertical grooves parallel to the central axis of the rotating shaft 81, and the middle part of the track groove is a spiral groove with the central axis of the rotating shaft 81 as the axis of rotation). Then, the fixing pin 82 moves into the spiral groove inside the track groove, thereby driving the rotating shaft 81 to rotate, causing the first turntable 83 to rotate, driving the fixing block 84 to rotate around the central axis of the first turntable 83, driving the second turntable 85 to rotate, causing the clamping block 87 to drive the right end of the spring contact finger to move. The rotating shaft 81 rotates one revolution, causing the spring contact finger to coil in the forming cavity 10 (the forming cavity 10 is annular). At this time, continue to press down on the moving mold 4, and the fixing pin 82 is located in the vertical groove on the lower side of the track groove, and the rotating shaft 81 stops rotating.

[0024] The working principle of the spring contact finger bending forming mold provided by this utility model is as follows: When using the spring contact finger bending forming mold to bend and form the spring contact finger, the unbent spring contact finger is placed in the placement cavity 9 on the upper surface of the lower forming seat 3, so that the right end of the spring contact finger is located between the two clamping plates 86. The positioning pin 6 is inserted into the positioning hole 7, and the moving mold 4 is pushed downward, so that the moving mold 4 moves downward, causing the sliding pin 11 to move downward, driving the upper forming seat 5 to move downward, and driving the turntable 83 to move downward. As the upper forming seat 5 moves downward, the fixing block 84 is inserted into the mounting groove when the lower surface of the upper forming seat 5 is in contact with the upper surface of the lower forming seat 3. The lower end of the fixing block 84 presses against the inclined surface of the rear side of the clamping plate 86, causing the two clamping plates 87 to move towards each other. The spring 3 87 retracts, and the two clamping plates 87 clamp the right end of the spring contact finger. At this time, the moving mold 4 continues to move downward, the sliding column 11 moves upward relative to the moving mold 4, the spring 1 12 retracts, and the rotating shaft 81 moves upward in the clearance groove, so that the fixing pin 82 is on the track groove. The track groove moves within the vertical groove on the side (both ends of the track groove are vertical grooves parallel to the central axis of the rotating shaft 81, and the middle of the track groove is a spiral groove with the central axis of the rotating shaft 81 as the axis of rotation). Then, the fixing pin 82 moves into the spiral groove inside the track groove, thereby driving the rotating shaft 81 to rotate, causing the first turntable 83 to rotate, which in turn drives the fixing block 84 to rotate around the central axis of the first turntable 83, causing the second turntable 85 to rotate, causing the clamping block 87 to move the right end of the spring contact finger. The rotating shaft 81 rotates one revolution, causing the spring... The contact finger is coiled inside the forming cavity 10 (the forming cavity 10 is annular). At this time, the moving mold 4 is pressed down. The fixing pin 82 is located in the vertical groove on the lower side of the track groove. The rotating shaft 81 stops rotating until the lower surface of the moving mold 4 is in close contact with the upper surface of the forming seat 5. At this time, the moving mold 4 presses down on the protrusions on the left and right sides of the upper surface of the pressure block 13. The spring 14 contracts and the pressure block 13 moves down to press the spring contact finger located inside the forming cavity 10, thereby giving the spring contact finger vertical pressure and reducing the rebound stress inside the spring contact finger.
