Description

Technical Field

[0001] This utility model relates to a bending device, and more particularly to a spring processing bending device, belonging to the field of spring processing technology. Background Technology

[0002] A spring is a mechanical part that works by utilizing elasticity. Parts made of elastic materials deform under external force and return to their original shape after the force is removed; they are generally made of spring steel. Springs come in a wide variety of types. Based on the nature of the force applied, springs can be classified as tension springs, compression springs, torsion springs, and bending springs. Based on their shape, they can be classified as disc springs, ring springs, leaf springs, helical springs, and torsion bar springs, among others.

[0003] The "Bending Device for Quick-Change Spring Production and Processing" disclosed in application number "202011276830.9" includes a device body. The device body has a left-right fixed guide plate at its bottom, and a right-right support plate is fixedly mounted on the top end of the fixed guide plate via bolts. A left-right support rotating shaft is fixedly mounted on the left side of the support plate via a bearing, and a meshing power wheel is mounted on the right side of the support rotating shaft via a key. A spring push block is installed at the front of the right side of the top end of the fixed guide plate, and a right-right support moving plate is installed at the left side of the top end of the fixed guide plate. In this utility model, the support rotating shaft is conveniently fixed inside the support plate via a bearing and driven to rotate by the meshing power wheel. This facilitates synchronous rotation of the winding roller sleeve, solving the problems of needing to replace the entire integrated structure after damage and the inability to replace different winding rollers according to the spring diameter.

[0004] However, the above method still has the following drawbacks: when it is necessary to replace the winding rollers of different sizes, the distance between the pressing moving plate and the winding roller is preset and fixed, and the distance between the limit guide wheel and the spring cannot be adjusted. After replacing the rollers of different sizes, the distance between the two cannot be adapted to the new working conditions, which will cause the limit guide wheel to fail to limit and guide the spring. Utility Model Content

Detailed Implementation

[0023] 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.

[0024] Please see Figure 1-6 This utility model provides a spring processing and bending device, including a base 1, with support plates 2 on both sides of the top of the base 1, and a rotating rod 3 rotatably mounted between the support plates 2. A roller 5 is slidably mounted on the surface of the rotating rod 3 through two sliding strips 4, and a spring body 6 is sleeved on the surface of the roller 5. A pressure block 7 is pressed onto the end of the spring body 6, and an adjustment component 12 is provided on the top of the pressure block 7. A base plate 9 is slidably mounted in the middle of the top of the base 1, and a moving plate 10 is slidably mounted on the top of the base plate 9. A limiting guide wheel 8 is provided on one side of the moving plate 10 to limit and guide the spring body 6, and a moving component 11 is provided on the top of the moving plate 10 to move the limiting guide wheel 8. The moving component 11 is raised to adjust the horizontal and vertical distances of the moving plate 10, thereby adjusting the horizontal distance of the limiting guide wheel 8. This allows the limiting guide wheel 8 to guide and limit the spring body 6 according to the need to replace rollers 5 of different sizes, further expanding its application range.

[0025] The moving assembly 11 includes a screw 1101, which is threadedly connected to the top of the moving plate 10 via a limiting nut. A slide block 1102 is rotatably mounted at the bottom end of the screw 1101. A limiting guide wheel 8 is rotatably mounted inside the slide block 1102. Two support rods 1103 are symmetrically slidably mounted inside the slide block 1102, and both ends of the support rods 1103 are fixedly connected to the inner wall of the moving plate 10. A knob 1104 is fixedly mounted at the top end of the screw 1101. A screw 2 1105 is threadedly connected to the top of the base plate 9 via a limiting nut. One end of the screw 2 1105 is rotatably connected to the moving plate 10, and a knob 2 1106 is fixedly mounted at the other end of the screw 2 1105. A limiting block 1107 is fixedly mounted at the bottom end of the moving plate 10. The top end has a limiting groove that slides with the limiting block 1107. Through the movable component 11, the knob 1104 can drive the screw 1101 to rotate, which, combined with the support rod 1103, can drive the slide 1102 to move in the vertical direction, thereby driving the limiting guide wheel 8 to adjust in the vertical direction. Furthermore, through the knob 1106, the screw 1105 can rotate, which, combined with the limiting block 1107, can adjust the horizontal distance of the movable plate 10, thereby adjusting the horizontal distance of the limiting guide wheel 8. This allows the limiting guide wheel 8 to guide and limit the spring body 6 according to the replacement needs of rollers 5 of different sizes, further expanding its application range.

[0026] The adjusting assembly 12 includes a mounting bracket 1201, which is positioned above the pressure block 7. The bottom end of the mounting bracket 1201 is fixedly connected to one side of the top end of the roller 5. The top of the mounting bracket 1201 is threadedly connected to a screw rod 1202 via a locking nut. The bottom end of the screw rod 1202 is rotatably connected to the top end of the pressure block 7. A knob 1203 is fixedly mounted on the top end of the screw rod 1202. A guide block 1204 is fixedly mounted on one side of the pressure block 7. A guide groove is provided on the inner wall of the mounting bracket 1201 to guide and cooperate with the guide block 1204. By rotating the knob 1203 through the adjusting assembly 12, the screw rod 1202 can be rotated. Combined with the guide block 1204, this allows the pressure block 7 to press and fix the spring body 6, making it more convenient to use.

[0027] A slider 18 is fixedly installed at the bottom of the support plate 2 on the left side. A groove is opened at the top of the base 1 to slide with the slider 18. An electric push rod 16 is fixedly installed on one side of the top of the base 1. A fixing plate 17 is fixedly installed on the telescopic rod of the electric push rod 16. One side of the fixing plate 17 is fixedly connected to the bottom of one side of the support plate 2. The electric push rod 16 can be used to push the left support plate 2 to move, so that the roller 5 that is slidably installed on the surface of the rotating rod 3 can be disassembled and replaced.

[0028] Two guide rods 13 are symmetrically slidably provided at the bottom of the base plate 9, and support blocks 14 are fixedly provided at both ends of the guide rods 13. The support blocks 14 are fixedly connected to the base 1. An electric telescopic column 15 is fixedly provided at the middle of the top of the base 1. The telescopic rod of the electric telescopic column 15 is fixedly connected to the middle of one side of the base plate 9. The guide rods 13 are provided to facilitate the limiting and guiding function of the base plate 9 when it moves along the direction of the base 1, thereby improving its stability during movement. The electric telescopic column 15 is provided to drive the base plate 9 to move, which facilitates the bending and use of the spring body 6.

[0029] The left support plate 2 has a moving groove in the middle that moves in conjunction with the rotating rod 3. A motor 19 is fixedly installed in the middle of the left support plate 2, and the output shaft of the motor 19 is fixedly connected to one end of the rotating rod 3. This allows the left support plate 2 to be separated from the rotating rod 3 by moving the left support plate 2 in conjunction with the moving groove, thereby enabling the roller 5, which is slidably mounted on the surface of the rotating rod 3, to be disassembled and replaced. The motor 19 facilitates the rotation of the rotating rod 3 and the roller 5, allowing the spring body 6 to be processed and bent.

[0030] In use, first, replace the roller 5 with one of the appropriate size as needed. Move the electric actuator 16 in conjunction with the fixing plate 17 to move the left support plate 2. Then, use the slide bar 4 to slide the roller 5 to the outside of the rotating rod 3, so that one end of the roller 5 is in contact with the right support plate 2. Then, repeat the above steps to reset the left support plate 2. Rotate the screw 1202 by the knob 1203 to press and fix the end of the spring body 6 with the pressure block 7. Then, adjust the position of the limit guide wheel 8 as needed. Rotate the screw 1101 by the knob 1104, which, in conjunction with the support rod 1103, can drive the slide 1102 to move vertically. The movement of the movable plate 10 allows for vertical adjustment of the guide wheel 8. The knob 1106 rotates the screw 1105, which, in conjunction with the limit block 1107, adjusts the horizontal distance of the movable plate 10, thereby adjusting the horizontal distance of the guide wheel 8. This ensures the guide wheel 8 is in contact with the surface of the spring body 6. The motor 19 then drives the rotating rod 3 and roller 5 to rotate. Simultaneously, the electric telescopic column 15 adjusts according to the spacing of the spring bodies 6, allowing the spring bodies 6 to wrap around the surface of the roller 5. Finally, the movement of the left support plate 2 removes the spring bodies 6 from the surface of the roller 5.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
