Description

Technical Field

[0001] This utility model relates to the field of wire production, and in particular to an embedded cam. Background Technology

[0002] The existing patent application publication number CN118595339A discloses a progressive conductor stamping device. Its description discloses that the outer circumference of the second rotating wheel has outwardly protruding protrusions and inwardly recessed grooves, with the protrusions and grooves arranged adjacent to each other. When the end of the second sliding plate in the length direction abuts against the protrusions, the second sliding plate drives the forming impact head to strike the front end of the conductor. At this time, the forming impact head has the longest impact stroke. When the end of the second sliding plate in the length direction abuts against the groove, the second sliding plate drives the forming impact head to reset. The outer circumference of the second rotating wheel also has a retraction area with protrusions at both ends. The depth of the retraction area is deeper than the depth of the groove. When the end of the second sliding plate overlaps the retraction area, the second sliding plate drives the forming impact head to retract. At this time, the forming impact head is farthest away from the front end of the conductor.

[0003] Multiple protrusions are distributed on the outer circumference of the second wheel. The height of the protrusions on both sides is higher than that of the protrusion in the middle. In this way, the end of the second slide plate overlaps with the protrusions at different heights, and the impact stroke of the forming impact head is different. The higher the protrusion, the longer the impact stroke of the forming impact head. The impact assembly also includes an impact spring. The two ends of the impact spring are connected to the second slide plate and the base respectively. In this way, when the second slide plate retracts, it retracts under the action of the impact spring.

[0004] Because the protrusion abuts against the end of the second slide plate along its length during rotation, the protrusion collides with the end of the second slide plate along its length. The protrusion with a longer radial length drives the second slide plate to move a greater distance. Over time, the protrusion with a longer radial length is prone to damage. However, replacing the entire second wheel would be a loss in terms of both time and economy, and the replacement process would be difficult. Utility Model Content

[0005] The purpose of this invention is to provide an embedded cam, which solves the problem of difficulty in replacing damaged impact parts on the cam.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: This utility model provides an inlay cam, including a cam body and an insert. The cam body has a groove on its radial outer periphery, and the insert is detachably disposed in the groove. The insert has a first impact portion, a second impact portion, and a concave surface on its radial outer periphery. The concave surface is located between the first impact portion and the second impact portion. The first impact portion and the second impact portion protrude from the radial outer periphery of the cam body and are smoothly transitioned and spliced ​​together with the radial outer periphery of the cam body.

[0007] Optionally, the groove is provided with a first inclined surface and a second inclined surface in the radial direction, and the first and second inclined surfaces extend outwards.

[0008] Furthermore, the groove is provided with a first cleaning groove and a second cleaning groove, the first cleaning groove being located at the bottom of the first inclined surface and the second cleaning groove being located at the bottom of the second inclined surface.

[0009] Furthermore, the inner end of the groove is provided with a first bottom surface, a second bottom surface, and a third bottom surface. The first bottom surface and the third bottom surface are inclined surfaces. The second bottom surface is located between the high end of the first bottom surface and the high end of the third bottom surface. The first cleaning groove is also located at the low end of the first bottom surface, and the second cleaning groove is also located at the low end of the third bottom surface.

[0010] Furthermore, the bottom of the insert is provided with a clearance groove, and the bottom of the insert is also provided with a first overlapping surface and a second overlapping surface. The clearance groove is located between the first overlapping surface and the second overlapping surface. The first overlapping surface is attached to the first bottom surface, and the second overlapping surface is attached to the third bottom surface. The clearance groove passes through both ends of the insert along its axial direction, and the second bottom surface is located at the radial opening end of the clearance groove.

[0011] Optionally, the top end of the first impact portion has a first impact surface, and the top end of the second impact portion has a second impact surface.

[0012] Optionally, the radial outer periphery of the cam body is provided with a plurality of inwardly recessed curved grooves and a plurality of outwardly protruding bumps. The curved grooves and the bumps are smoothly transitioned and adjacent to each other. The first impact part and the second impact part are respectively smoothly transitioned and spliced ​​together with two of the curved grooves. The protruding length of the bumps is less than the protruding length of the first impact part and the second impact part.

[0013] Furthermore, a retraction area is provided on the radial outer periphery of the cam body, and the two ends of the retraction area smoothly transition to the protrusion and the second impact part, respectively.

[0014] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art: The inlay cam of this utility model has a groove on the cam body, and the insert can be detachably installed in the groove. When the first impact part and the second impact part are damaged, the insert can be directly removed from the groove and a new insert can be installed in the groove. At this time, there are new first impact parts and second impact parts. Replacing the insert is simpler and cheaper than replacing the cam. Therefore, it solves the problem of difficult replacement of the impact part on the cam. Attached Figure Description

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0019] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0020] like Figure 1 and Figure 2 and Figure 3 As shown, the inlaid cam includes a cam body 1 and an insert 2. The cam body 1 has a groove 11 on its radial outer periphery. The insert 2 is detachably disposed in the groove 11. The insert 2 has a first impact part 21, a second impact part 22 and a concave surface 23 on its radial outer periphery. The concave surface 23 is located between the first impact part 21 and the second impact part 22. The concave surface 23 is recessed inward, while the first impact part 21 and the second impact part 22 are protruding outward. The first impact part 21, the concave surface 23 and the second impact part 22 are smoothly connected together, that is, there is no step between the first impact part 21, the concave surface 23 and the second impact part 22.

[0021] The first impact portion 21 and the second impact portion 22 protrude from the radial outer periphery of the cam body 1, meaning that the first impact portion 21 and the second impact portion 22 extend further radially than the radial outer periphery of the cam body 1. The first impact portion 21 and the second impact portion 22 are smoothly connected to the radial outer periphery of the cam body 1. The first side of the groove 11 has the radial outer periphery of the cam body 1, and the first impact part 21 is smoothly connected to the radial outer periphery of the cam body 1 at that location. The second side of the groove 11 has the radial outer periphery of the cam body 1, and the second impact part 22 is smoothly connected to the radial outer periphery of the cam body 1 at that location.

[0022] The groove 11 is provided with a first inclined surface 13 and a second inclined surface 14 in the radial direction. The groove 11 passes through both ends of the axial direction of the cam body 1. The first inclined surface 13 and the second inclined surface 14 extend outward, that is, the radial opening end size of the groove 11 is larger than the inner end size. The groove 11 extends outward. In other embodiments, the first inclined surface 13 and the second inclined surface 14 may not extend in the radial direction of the groove 11.

[0023] The recess 11 is provided with a first cleaning groove 15 and a second cleaning groove 16. The first cleaning groove 15 is located at the bottom of the first inclined surface 13, and the second cleaning groove 16 is located at the bottom of the second inclined surface 14. If there are impurities or dust inside the recess 11, the impurities or dust can be cleaned into the first cleaning groove 15 and the second cleaning groove 16 to prevent impurities or dust from hindering the installation of the insert 2.

[0024] The inner end of the groove 11 is provided with a first bottom surface 17, a second bottom surface 18, and a third bottom surface 19. The first bottom surface 17 and the third bottom surface 19 are connected to the inclined surface of the second bottom surface 18. The second bottom surface 18 is located between the high end of the first bottom surface 17 and the high end of the third bottom surface 19. The first cleaning groove 15 is also located at the low end of the first bottom surface 17, and the second cleaning groove 16 is also located at the low end of the third bottom surface 19. In this way, impurities falling on the first bottom surface 17 and the second bottom surface 18 can slide from the first bottom surface 17 into the first cleaning groove 15, and impurities falling on the second bottom surface 18 and the third bottom surface 19 can slide from the third bottom surface 19 into the second cleaning groove 16. The impurities accumulated in the first cleaning groove 15 and the second cleaning groove 16 are cleaned regularly.

[0025] The bottom of the insert 2 is provided with a relief groove 24, which is opposite to the concave surface 23. The bottom of the insert 2 is also provided with a first overlapping surface 25 and a second overlapping surface 26. The relief groove 24 is located between the first overlapping surface 25 and the second overlapping surface 26. The first overlapping surface 25 is attached to the first bottom surface 17, and the second overlapping surface 26 is attached to the second bottom surface 18. The first overlapping surface 25 is opposite to the first impact part 21, and the second overlapping surface 26 is opposite to the second impact part 22.

[0026] The clearance groove 24 passes through both ends of the insert 2 in the axial direction. The second bottom surface 18 is located at the radial opening end of the clearance groove 24. If impurities are present on the second bottom surface 18, the clearance groove 24 can avoid these impurities when fixing the insert 2. The insert 2 is fixed on the second bottom surface 18 by bolts.

[0027] The top end of the first impact part 21 has a first impact surface 27, and the top end of the second impact part 22 has a second impact surface 28. The first impact surface 27 and the second impact surface 28 are used to press against the skateboard to be impacted (not shown in the figure). The first impact surface 27 and the second impact surface 28 increase the contact area with the skateboard.

[0028] The cam body 1 has multiple inwardly recessed curved grooves 10 and multiple outwardly protruding protrusions 12 on its radial outer periphery. The curved grooves 10 and protrusions 12 are smoothly transitioned and adjacent to each other. The multiple protrusions 12 are located on different circumferences, that is, the multiple protrusions 12 have different heights. In this way, the multiple protrusions 12 drive the slide plate to move different distances. The first impact part 21 and the second impact part 22 are smoothly connected to the two curved grooves 10 respectively. The radius of the circumference where the protrusion 12 is located is smaller than the radius of the circumference where the first impact part 21 and the second impact part 22 are located, that is, the distance that the protrusion 12 drives the slide plate to move.

[0029] A retraction area 100 is provided on the radial outer periphery of the cam body 1. The two ends of the retraction area 100 smoothly transition to the engagement protrusion 12 and the second impact part 22, respectively. The depth of the retraction area 100 is deeper than the depth of the curved groove 10 and the concave surface 23.

[0030] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the protection scope of this utility model.
