Description

Technical Field

[0001] This invention specifically relates to a multi-layer wave spring processing device. Background Technology

[0002] Wave springs are ring-shaped elastic metal elements with alternating crests and troughs. They are widely used in mechanical seals, vibration damping, preload and axial compensation. In the production process, common wave spring processing equipment often uses a cylinder to drive a push plate, so that the metal strip is bent into shape by the up and down movement of the push plate.

[0003] The existing cylinder reciprocating motion speed is slow, which limits the improvement of production cycle. At the same time, the cylinder stroke is fixed, making it difficult to flexibly adjust the height of the peaks and troughs, resulting in poor equipment adaptability and inability to meet the processing requirements of wave springs of different specifications. In addition, metal strips are prone to twisting and deformation during conveying and bending, affecting the dimensional accuracy and appearance quality of the final product. To address this, we propose a multi-layer wave spring processing device. Summary of the Invention

[0004] The purpose of this invention is to provide a multi-layer wave spring processing device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a multi-layer wave spring processing device, comprising:

[0006] A base, on which are distributed bending rollers for bending metal strips, and a feeding assembly is provided on one side of the base;

[0007] A mounting plate is disposed on the other side of the base, and one side of the mounting plate has a guide plate for guiding the metal strip;

[0008] A push plate is connected to one side of the mounting plate via a sliding assembly, and the push plate and the guide plate are arranged side by side to push the metal strip to form a wave shape, and one end of the inner side of the push plate has a through groove that cooperates with the metal strip.

[0009] A reset spring is disposed on the lower surface of the push plate, and one end of the reset spring cooperates with the sliding assembly;

[0010] The motor is fixed to the other side of the mounting plate, and the output end of the motor is connected to a rotating shaft that passes through one side of the mounting plate;

[0011] A drive wheel is mounted on the rotating shaft, and a top block that pushes the push plate to move up and down is detachably connected to the outer wall of the drive wheel.

[0012] Preferably, a cutting blade is provided on one side of the push plate to form a wave spring for cutting, and the lower end of the cutting blade has a telescopic cylinder.

[0013] Preferably, a guiding inclined block for spirally upward metal strips is fixed on the base, and a straightening component for correcting the metal strips is connected between one side of the guiding inclined block and the base.

[0014] Preferably, the straightening component includes a support base, a first bracket, a second bracket and straightening wheels. The support base is fixed on the base, and the second bracket and the first bracket are sequentially arranged along the long side of the support base. The first bracket is slidably matched with an adjustment groove opened on the support base. Straightening wheels are rotatably installed on the inner sides of the second bracket and the first bracket. One end of the support base is connected with an adjustment screw rod for adjusting the position of the first bracket through a threaded part.

[0015] Preferably, at least two straightening wheels are evenly distributed along one long side of the first bracket.

[0016] Preferably, the sliding component includes a guiding slider and a ball. The guiding slider is fixed on one side of the mounting plate, and a sliding groove for cooperating with the guiding slider is opened at the other end of the push plate, and balls contacting the guiding slider are arranged inside the sliding groove.

[0017] Preferably, two reset springs are provided, and two ends of each reset spring are respectively cooperated with the push plate and the guiding slider.

[0018] Preferably, a groove is opened on the lower surface of the push plate, and a connecting roller contacting the driving wheel is rotatably installed inside the groove.

[0019] Preferably, the cross section of the driving wheel is in a "U" shape, through holes are opened on the side wall of the driving wheel along its circumferential direction, and the top block is fixed to the driving wheel through the through holes and bolts.

[0020] Preferably, the motor is a servo motor.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] (1) By arranging a motor, a rotating shaft, a driving wheel and a reset spring, the present invention avoids the traditional push plate being driven by a cylinder to move up and down reciprocally. The reciprocating movement speed of the cylinder is slow, and it is not convenient to adjust the troughs and peaks of the wave springs. This device drives the driving wheel to rotate through the motor to drive the push plate to move up and down reciprocally, greatly improving the movement efficiency. And later, by replacing the top block, it is easy to realize troughs and peaks of different heights, which is beneficial to the processing of wave springs of different specifications, increasing the practicability of the device.

[0023] (2) By setting up a support base, a first bracket, a second bracket and a straightening wheel, the metal strip is prevented from twisting and deforming during transportation and feeding, which affects the quality and appearance of the product. This device can correct the metal strip during processing, reduce the twisting, improve the product quality, and has a simple structure. The correction spacing can be adjusted according to the metal strip of different widths in the later stage, which improves the applicability. Attached Figure Description

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see Figures 1-7 The present invention provides a technical solution: a multi-layer wave spring processing device, comprising:

[0034] Base 1, with bending rollers 2 for bending metal strips distributed on the base 1, and a feeding assembly 4 provided on one side of the base 1;

[0035] Mounting plate 5 is located on the other side of base 1, and one side of mounting plate 5 has guide plate 8 for guiding metal strips;

[0036] Push plate 7 is connected to one side of mounting plate 5 via sliding assembly, and push plate 7 and guide plate 8 are arranged side by side to push metal strip to form a wave, and push plate 7 has a through groove 71 on one inner end that cooperates with metal strip.

[0037] A return spring 66 is disposed on the lower surface of the push plate 7, and one end of the return spring 66 is engaged with the sliding component;

[0038] This allows the pusher plate 7 to move downwards after pushing the metal strip upwards, thus achieving a reset.

[0039] Motor 61 is fixed to the other side of mounting plate 5, and the output end of motor 61 is connected to a rotating shaft 62 that passes through one side of mounting plate 5;

[0040] The drive wheel 63 is mounted on the rotating shaft 62, and the outer wall of the drive wheel 63 is detachably connected to a top block 65 that pushes the push plate 7 to move up and down; this facilitates the periodic movement of the top block 65 driven by the drive wheel 63, thereby realizing the reciprocating movement of the push plate 7 to push the metal strip to deform and form troughs and crests.

[0041] This invention uses a motor 61 in conjunction with a drive wheel 63 and a top block 65 to drive the push plate 7, replacing the traditional cylinder drive. This mechanical structure, which converts rotary motion into linear reciprocating motion, not only has a faster operating speed and higher efficiency, but also smoother movement and lower noise. More importantly, the detachable design of the top block 65 makes it extremely easy to adjust the height of the crests and troughs. Simply replace the top block 65 with one of different protrusion heights, which greatly enhances the equipment's ability to process products of different specifications.

[0042] Preferably, a cutting blade 10 is provided on one side of the push plate 7 to form a wave spring for cutting, and the lower end of the cutting blade 10 has a telescopic cylinder.

[0043] Preferably, a guide block 3 is fixed on the base 1 to make the metal strip spiral upward, and a straightening component 9 for correcting the metal strip is connected to one side of the guide block 3 and the base 1.

[0044] This allows the metal strip to be straightened before it is bent by the bending roller 2, reducing the twisting of the metal strip and affecting the quality in the later stages.

[0045] Preferably, the straightening component 9 includes a support base 91, a first bracket 94, a second bracket 95 and straightening wheels 96. The support base 91 is fixed to the base 1, and the second bracket 95 and the first bracket 94 are sequentially arranged along the long side of the support base 91. The first bracket 94 is slidably engaged with an adjustment groove 93 opened on the support base 91. Straightening wheels 96 are rotatably installed on the inner sides of the second bracket 95 and the first bracket 94. One end of the support base 91 is connected with an adjustment screw 92 for adjusting the position of the first bracket 94 through a threaded portion;

[0046] There are at least two straightening wheels 96 evenly distributed along one long side of the first bracket 94;

[0047] By screwing the adjustment screw 92, the first bracket 94 can be driven to move, thereby changing the distance between the two groups of straightening wheels 96 to adapt to metal strips of different widths. This component eliminates the adverse effects of the distortion of the metal strip on the product quality at the source, ensuring that the finally formed wave spring has a regular shape.

[0048] Preferably, the sliding component includes a guiding slider 64 and ball bearings 74. The guiding slider 64 is fixed to one side of the mounting plate 5. The other end of the pushing plate 7 is provided with a sliding groove 73 that cooperates with the guiding slider 64, and ball bearings 74 that contact the guiding slider 64 are arranged inside the sliding groove 73;

[0049] There are two reset springs 66, and the two ends of the reset springs 66 are respectively cooperated with the pushing plate 7 and the guiding slider 64;

[0050] Through the sliding of the guiding slider 64 in cooperation with the sliding groove 73 with ball bearings 74 and with the reset springs 66, this structure greatly reduces the frictional resistance and wear during the reciprocating movement of the pushing plate 7, ensuring the efficiency, smoothness and low noise of the movement process. The symmetrical design of the double reset springs 66 further ensures the balanced force of the pushing plate 7, avoids unilateral jamming, and improves the stability of the movement.

[0051] Preferably, a groove is opened on the lower surface of the pushing plate 7, and a connecting roller 72 that contacts the driving wheel 63 is rotatably installed inside the groove;

[0052] It is convenient to better reduce the sliding friction.

[0053] Preferably, the cross-section of the driving wheel 63 is "U" shaped, through holes are opened on the side wall of the driving wheel 63 along its circumference, and the top block 65 is fixed to the driving wheel 63 through the through holes and bolts;

[0054] It is convenient to replace the top block 65 later to process wave springs with different specifications of wave peaks and wave valleys.

[0055] Preferably, the motor 61 is a servo motor;

[0056] It is convenient to accurately control the movement frequency of the pushing plate 7.

[0057] The working principle and usage process of this invention are as follows: During use, the feeding assembly 4 rotates to move the metal strip. Multiple bending rollers 2 bend the metal strip. The guide plate 8 guides the bent metal strip. The motor 61 drives the drive wheel 63 to rotate via the shaft 62. When the top block 65 on the outer wall of the drive wheel 63 contacts the connecting roller 72, the push plate 7 moves upward. At this time, the reset spring 66 elastically elongates. The push plate 7 bends the metal strip through the through groove 71 to form a wave crest. When the top block 65 is not in contact with the connecting roller 72, the metal strip forms a wave trough. Then, the inclined surface of the guide block 3 guides the metal strip, causing it to spiral upwards, thus automatically winding and forming a multi-layered wave spring. At this time, the telescopic cylinder drives the cutting blade 10 to rise, cutting the formed wave spring from the metal strip. Similarly, by changing different top blocks 65, wave springs with different crests and troughs can be formed, such as... Figure 7 The image shows a wave spring that has been manufactured.

[0058] Although embodiments of the 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 invention, the scope of which is defined by the appended claims and their equivalents.
