Description

Technical Field

[0001] This utility model relates to the field of spring processing equipment technology, and in particular to an integrated device for forming and discharging compression springs. Background Technology

[0002] A compression spring is a mechanical component that uses the elastic deformation of a helical metal wire, usually spring steel, to withstand axial pressure and store energy. Its core structure consists of helical coils with uniform spacing, which achieve linear elastic deformation through Hooke's Law. When the external force is removed, it can return to its original shape. Compression springs are widely used in mechanical buffers, vehicle suspensions, industrial valves, electronic equipment and other fields, and undertake functions such as shock absorption, energy storage, reset or maintaining pressure balance between components.

[0003] In the compression spring forming process, the lack of an online deburring function module in existing equipment forces the production line to be equipped with an independent deburring station for secondary processing, resulting in a broken process chain, an increased damage rate of springs during secondary clamping, and an increase in the overall processing cost per piece.

[0004] Therefore, we propose an integrated compression spring forming and discharge device to solve the problems mentioned above. Utility Model Content

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention can also be implemented in other ways than those described herein, and therefore the present invention is not limited to the specific embodiments disclosed in the following specification.

[0026] Example 1, such as Figures 1-3 As shown, this utility model provides an integrated device for compression spring forming and discharging: including a base 1 and a bracket 2 vertically fixed to the upper end of the base 1. The front side of the bracket 2 is sequentially equipped with a longitudinal drive mechanism 3, a feeding mechanism 4 and a radial drive mechanism 5.

[0028] The feeding mechanism 4 includes a transverse drive assembly 41 and a forming assembly 42 fixedly installed on the front side of the bracket 2. A first locking plate 43 fixedly installed on the front side of the bracket 2 is provided below the transverse drive assembly 41.

The second material passage pipe 45 is fixedly installed on the front side of the bracket 2 by a second locking plate 46.

[0029] The overall effect of Embodiment 1 is as follows: through the lateral driving and conveying of the lateral drive component 41 and the synchronous process of friction deburring, combined with the V-shaped cut 335 swing cutting mechanism and the second positioning block 53 and the abutment 54 of the elastic ejection component, the integrated production of continuous spring forming, precision cutting and directional ejection is realized, eliminating the surface damage caused by secondary clamping in the traditional process, shortening the processing time of a single piece, and reducing the burr defect rate.

[0030] Example 2, as Figures 1-2 and Figure 4 As shown, this utility model provides an integrated device for spring forming and discharging: the cutting component 33 includes a positioning plate 331, which is fixedly installed on the upper end of the wedge-shaped connector 32 by a nut. A spring 332 is installed on the lower end of the positioning plate 331. The other end of the spring 332 is elastically connected to a vertical plate 333 fixedly installed on the front side of the bracket 2. A beveled cutting blade 334 is connected to the lower end of the vertical plate 333. The blade of the beveled cutting blade 334 is provided with a V-shaped cut 335. The longitudinal drive mechanism 3 also includes a fixing plate 34 fixedly installed on the front side of the bracket 2. A servo motor 35 is installed on the fixing plate 34.

[0031] The effect achieved by the entire embodiment 2 is as follows: through the precise transmission of the crank-slider mechanism, the wedge-shaped groove fixing plate 31 and the wedge-shaped connector 32 and the elastic buffering of the spring 332, the beveled cutting blade 334 achieves the swing cutting angle, and with the bidirectional shearing force of the V-shaped cut 335, the burrs on the end face of the compression spring are reduced.

[0032] Example 3, as Figures 1-2As shown, this utility model provides an integrated device for forming and discharging compression springs: the number of transverse drive components 41 is two sets, and the two sets of transverse drive components 41 are symmetrically distributed vertically. The transverse drive component 41 includes a low-speed motor 411 fixedly installed on the front side of the bracket 2 via a connecting plate. The output shaft of the low-speed motor 411 is connected to a second bearing 412. A roller 413 is nested outside the second bearing 412. The outer circumferential surface of the roller 413 is precision machined with a guide groove 414 with a semi-circular cross section. The two rollers 413 form a paired forming roller set. The two guide grooves 414 are molded together to form a complete cylindrical channel. The forming component 42 includes a fixing clamp 421 fixedly installed on the front side of the bracket 2. A first positioning block 422 is engaged inside the fixing clamp 421. One end of the first positioning block 422 is fixed. A cylindrical guide head 423 is connected. The cross-section of the first half of the cylindrical guide head 423 near the beveled cutting blade 334 is half the cross-section of the second half. A semi-circular groove is longitudinally opened on the end face of the cylindrical guide head 423 near 434. There are two sets of forming components 42, which are symmetrically distributed vertically. The semi-circular grooves opened on the end faces of the two cylindrical guide heads 423 and the circular guide groove opened inside the second feed pipe 45 extend in the same circumference. The ends of the first feed pipe 44 and the second feed pipe 45 near the roller 413 are pointed and are respectively engaged between a set of rollers 413. The beveled end of the beveled cutting blade 334 fits with the circumferential surface of the cylindrical guide head 423. Its movement trajectory is constrained by the outer circumferential surface of the cylindrical guide head 423, forming a swing cutting path.

[0033] The overall effect achieved by embodiment 3 is as follows: through the coordinated guidance of the symmetrical pairing forming roller group and the dual-channel pointed feed tube, and the constraint of the semi-circular groove of the cylindrical guide head 423, the surface burrs of the wire are reduced during the spiral forming process. At the same time, the swaying cutting path and the forming trajectory are precisely matched to reduce the burrs on the cutting surface.

[0034] Example 4, as Figures 1-2 As shown, this utility model provides an integrated device for forming and discharging materials using a compression spring: the radial drive structure 5 includes a snap-fit ​​plate 51 fixedly installed on the front side of the bracket 2. The snap-fit ​​plate 51 has a square groove inside, and a connecting block 52 is slidably connected in the square groove. A second positioning block 53 is installed on the outside of the connecting block 52. A stop post 54 is installed on the lower left side of the second positioning block 53. A second spring 55 is installed on the back of the connecting block 52. The other end of the second spring 55 is fixedly installed on the front side of the bracket 2. A hydraulic cylinder 56 is installed on the left side of the snap-fit ​​plate 51. A paddle 57 is installed on the drive shaft of the hydraulic cylinder 56 to form a radial ejection mechanism.

[0035] The effect achieved by the entire embodiment 4 is that the forward ejection of the paddle 57 driven by the hydraulic cylinder 56 and the elastic reset of the second spring 55 are coordinated to realize the synchronization of the formation of the compression spring helical structure and the ejection action.

[0036] The working principle of the entire device is as follows:

[0037] Wire conveying and spiral forming: High carbon steel wire is introduced through the first feed pipe (44) and the second feed pipe (45). Two sets of low-speed motors (411) drive rollers (413) to rotate synchronously in opposite directions. The semi-circular guide groove (414) of the roller (413) closes the mold to form a complete cylindrical channel, which drives the steel wire to be conveyed to the right. The inner wall of the guide groove (414) rubs against the surface of the wire to remove the microburrs generated during the forming process. The front end of the wire enters the cylindrical guide head (423) of the two forming components (42). Its semi-circular groove constrains the movement trajectory of the wire, so that the steel forms a ring.

[0038] Synchronous swing cutting and burr control: The servo motor (35) drives the first bearing (36), and the rotational motion is converted into the vertical reciprocating motion of the wedge connector (32) through the L-shaped connector (37). The beveled cutting blade (334) is constrained by the outer circumference of the cylindrical guide head (423) to form a swing cutting angle, avoiding material flipping caused by straight cutting. During the downward movement of the cutting blade, the V-shaped cut (335) applies pressure to the wire to achieve double bevel shearing, which reduces the end face burr rate. The spring (332) provides elastic stroke at the moment of cutting to offset the material rebound impact and ensure the flatness of the cut.

[0039] Elastic ejection and directional collection: When the beveled cutting blade (334) descends to the bottom point, due to the constraint of the outer circumference of the cylindrical guide head (423), the beveled cutting blade (334) contacts and pushes the second positioning block (53) inward. When the beveled cutting blade (334) moves upward, the rebound force of the second spring (55) drives the abutment (54) to press the compression spring forward. At this time, the hydraulic cylinder (56) drives the paddle (57) to push outward. The outward pushing force of the paddle (57) is greater than the forward low pressure of the abutment (54) on the compression spring, so that the compression spring forms a spiral shape outward. At the same time, the paddle (57) ejects the formed compression spring outward and falls into the storage box (7).

[0040] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
