Description

Technical Field

[0001] This application relates to the field of spring manufacturing, and more specifically, to a feeding structure and a spring machine. Background Technology

[0002] A spring is a mechanical part that works by utilizing elasticity. Made of elastic material, it deforms under external force and returns to its original shape after the force is removed. It is also called a "spring". They are generally made of spring steel. Springs come in a wide variety of types; based on shape, they mainly include helical springs, spiral springs, leaf springs, and irregularly shaped springs.

[0003] Currently, in the process of processing wire raw materials into springs using a spring machine, the wire needs to be fed into the spring machine via conveyor rollers. However, wear and tear during long-term use causes the clamping force of the two conveyor rollers on the wire to loosen, which can easily cause the feeding to slip. Adjustments need to be made while maintaining concentricity. Utility Model Content

[0004] To overcome the above deficiencies, this application provides a feeding structure and a spring machine, which aim to improve the problems mentioned in the background art.

[0005] In a first aspect, embodiments of this application provide a feeding structure including a feeding assembly and a straightening assembly.

[0006] The feeding assembly includes a fixed plate, a connecting plate, a bidirectional lead screw, a moving block, a conveying wheel, a rotating shaft, a motor, a first bevel gear, and a second bevel gear. The connecting plate is disposed at the bottom of the fixed plate. The bidirectional lead screw is rotatably disposed between the two connecting plates. The moving block is threaded onto the bidirectional lead screw. The conveying wheel rotatably passes through the moving block. The rotating shaft rotatably is disposed between the two connecting plates. The motor is fixedly connected to the connecting plate and drivenly connected to the rotating shaft. The first bevel gear is fixedly connected to the bottom end of the conveying wheel. The second bevel gear is slidably disposed on the rotating shaft, and one end of the second bevel gear rotatably passes through the moving block. The first bevel gear and the second bevel gear mesh with each other.

[0007] The straightening assembly includes a support plate and a straightening wheel. The support plate is fixedly connected to the fixed plate, and the straightening wheel rotates through the support plate.

[0008] In one specific implementation, the fixing plate has an elongated hole, through which the shaft of the conveyor wheel slides.

[0009] In the above implementation process, an elongated hole is provided to guide and restrict the movement direction of the two transmission wheels.

[0010] In one specific implementation, the moving block is L-shaped, and the first bevel gear and the second bevel gear are located inside the moving block.

[0011] In one specific implementation, the second bevel gear is fixedly connected to a circular grooved cylinder, and the movable block is slidably sleeved on the circular grooved cylinder.

[0012] In the above implementation process, by setting a circular groove cylinder, the moving block and the second bevel gear are connected, and the relative rotation between the two can also be guaranteed.

[0013] In one specific implementation, the rotating shaft is fixedly connected to a limiting strip, and the circular groove cylinder and the second bevel gear are both adapted to be slidably sleeved on the limiting strip.

[0014] In the above implementation process, by setting a limit bar, the relative rotation of the rotating shaft and the second bevel gear is restricted, ensuring that the rotating shaft can drive the second bevel gear to rotate when it rotates.

[0015] In one specific implementation, one end of the bidirectional lead screw rotates through the connecting plate and is equipped with a handwheel.

[0016] In the above implementation process, a handwheel is provided to facilitate the rotation of the bidirectional lead screw by turning the handwheel, making operation convenient.

[0017] In one specific implementation, two sets of the support plate and the straightening wheel are arranged, and the two sets of the support plate and the straightening wheel are perpendicular to each other.

[0018] Secondly, this utility model also provides a spring machine including the above-mentioned feeding structure, and a spring machine assembly. The spring machine assembly includes a spring machine body and a base plate. The spring machine body is disposed on the top of the base plate, and the fixing plate is fixedly connected to the spring machine body.

[0019] Beneficial effects: This application provides a feeding structure and a spring machine. By setting a fixed plate, a connecting plate, a bidirectional lead screw, a moving block, a conveying wheel, a rotating shaft, a motor, a first bevel gear, and a second bevel gear, the distance between the two conveying wheels can be adjusted synchronously to ensure that the two conveying wheels have sufficient clamping force on the wire and can ensure that the two conveying wheels rotate synchronously to feed the wire, ensuring that the feeding does not slip and the feeding center position remains unchanged. By setting a support plate and a straightening wheel, the wire can be straightened. Attached Figure Description

Detailed Implementation

[0027] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0028] Please see Figures 1-5 This application provides a feeding structure including a feeding assembly 100 and a straightening assembly 200.

[0029] Please see Figure 1 , 23 and 4, the feeding assembly 100 includes a fixed plate 110, a connecting plate 120, a bidirectional lead screw 130, a moving block 140, a conveying wheel 150, a rotating shaft 160, a motor 170, a first bevel gear 180, and a second bevel gear 190. The connecting plate 120 is disposed at the bottom of the fixed plate 110. The bidirectional lead screw 130 is rotatably disposed between the two connecting plates 120. The moving block 140 is threadedly sleeved on the bidirectional lead screw 130. The conveying wheel 150 rotatably passes through the moving block 140. The rotating shaft 160 rotatably is disposed between the two connecting plates 120. The motor 170 is fixedly connected to the connecting plate 120 and is drivenly connected to the rotating shaft 160. The first bevel gear 180 is fixedly connected to the bottom end of the conveying wheel 150. The second bevel gear 190 is slidably sleeved on the rotating shaft 160, and one end of the second bevel gear 190 rotatably passes through the moving block 140. The first bevel gear 180 and the second bevel gear 190 mesh with each other.

[0030] The fixed plate 110 has an elongated hole 111 through which the shaft of the conveyor wheel 150 slides. The elongated hole 111 is used to guide and limit the movement direction of the two conveyor wheels 150.

[0031] Specifically, the moving block 140 is L-shaped, and the first bevel gear 180 and the second bevel gear 190 are located inside the moving block 140.

[0032] In this embodiment, the second bevel gear 190 is fixedly connected to the circular groove cylinder 191, and the moving block 140 is slidably sleeved on the circular groove cylinder 191. By setting the circular groove cylinder 191, the moving block 140 and the second bevel gear 190 are connected, and the relative rotation of the two can also be guaranteed.

[0033] It should be noted that the rotating shaft 160 is fixedly connected to the limiting strip 161, and the circular groove cylinder 191 and the second bevel gear 190 are both adapted to slide on the limiting strip 161. By setting the limiting strip 161, the relative rotation of the rotating shaft 160 and the second bevel gear 190 is restricted, ensuring that the rotating shaft 160 can drive the second bevel gear 190 to rotate when it rotates.

[0034] In one specific implementation, one end of the bidirectional lead screw 130 rotatably passes through the connecting plate 120 and is equipped with a handwheel 131. By providing the handwheel 131, it is convenient to drive the bidirectional lead screw 130 to rotate by rotating the handwheel 131, which facilitates operation.

[0035] Please see Figure 1 , 2 5. The straightening assembly 200 includes a support plate 210 and a straightening wheel 220. The support plate 210 is fixedly connected to the fixed plate 110, and the straightening wheel 220 rotates through the support plate 210.

[0036] In one specific implementation, two sets of support plates 210 and straightening wheels 220 are arranged, and the two sets of support plates 210 and straightening wheels 220 are perpendicular to each other.

[0037] Please see Figure 1 This utility model also provides a spring machine including the above-mentioned feeding structure, and a spring machine assembly 300. The spring machine assembly 300 includes a spring machine body 310 and a base plate 320. The spring machine body 310 is disposed on the top of the base plate 320, and the fixing plate 110 is fixedly connected to the spring machine body 310.

[0038] The feeding structure and working principle of the spring machine are as follows: During use, the wire is passed through the straightening rollers 220 and the conveyor rollers 150. The motor 170 is started, driving the rotating shaft 160 to rotate. With the cooperation of the limit bar 161, the rotating shaft 160 drives the second bevel gear 190 to rotate. The second bevel gear 190 meshes with and drives the first bevel gear 180 to rotate. The first bevel gear 180 drives the moving block 140 to rotate. The two moving blocks 140 rotate synchronously for feeding. When adjustment is needed after long-term use, the handwheel 131 is turned to drive the double-acting screw 130 to rotate. The double-acting screw 130 synchronously drives the two moving blocks 140 to move, and the moving blocks 140 drive the conveyor rollers 150 to move, thereby synchronously adjusting the two conveyor rollers 150. This allows adjustment of the distance between the two conveyor rollers 150 while ensuring the feeding centerline remains unchanged, and also allows for synchronous rotation in both directions, greatly improving practicality.

[0039] It should be noted that the specific model and specifications of the motor 170 and the spring mechanism body 310 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0040] The power supply and principle of the motor 170 and the spring mechanism body 310 are clear to those skilled in the art and will not be described in detail here.

[0041] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this application. No reference numerals in the claims should be construed as limiting the scope of the claims.
