Description

Technical Field

[0001] This utility model relates to the field of jewelry processing equipment technology, and in particular to a chain ring forming mechanism for an integrated real rope machine. Background Technology

[0002] A true rope chain is a chain formed by the interlocking and welding of multiple C-shaped links. Each C-shaped link has two weld points with its adjacent link, resulting in high connection strength, and it is widely used in jewelry making. A true rope machine is a device that processes metal wire into true rope chains. Link forming is a crucial step in chain manufacturing and other industrial processes. Traditional integrated true rope machines typically use a simple bending mechanism to bend straight metal wire into semi-circular links. In existing technologies, link forming mechanisms often rely on manual or mechanical drives, such as using a single push rod to drive a forming needle to engage with a semi-circular groove to complete the bending. However, such mechanisms often require manual reset after forming or use simple spring reset, resulting in low forming accuracy and unstable reset. Specifically, the lack of buffering and precise control during the movement of the forming needle easily leads to excessive deformation or wear of the wire, and insufficient coordination between the drive and reset components affects the efficiency and quality of continuous operation.

[0003] Therefore, it is necessary to provide a chain loop forming mechanism for an integrated real rope machine to overcome the above-mentioned defects. Utility Model Content

[0004] The purpose of this invention is to provide a chain ring forming mechanism for an integrated real rope machine, which aims to solve the problems of inaccurate movement and untimely reset of existing forming needles, thereby achieving efficient and stable chain ring forming.

[0005] To achieve the above objectives, this utility model provides a chain loop forming mechanism for an integrated real rope machine, comprising: Fixed block; the fixed block is provided with a sliding hole; The first straight cylinder has a forming needle at one end. The forming needle is used to cooperate with the semi-circular groove of the preset mechanism to bend the straight metal wire into a semi-circular shape. The second straight cylinder is stacked vertically with the first straight cylinder and both pass through the sliding hole; the end of the second straight cylinder near the forming needle is provided with an abutment block flush with the first straight cylinder; a compression spring is provided inside the second straight cylinder, and one end of the compression spring is connected to a pin; a strip-shaped sliding hole is provided on the side of the second straight cylinder near the first straight cylinder; a pressure rod is vertically provided on the first straight cylinder, passing through the strip-shaped sliding hole and abutting against the pin; A driving component is used to drive the first straight cylinder to move inward along the sliding hole so that the forming needle moves away from the corresponding position of the semicircular groove of the preset mechanism. A reset component is used to return the first cylinder to its position before it was driven by the drive component.

[0006] In a preferred embodiment, the end of the first straight cylinder away from the forming needle is provided with a drive groove; the drive assembly includes a connecting block disposed on the fixed block, a connecting rod connected to the connecting block via a rotating shaft, and a drive rod disposed at the end of the connecting rod away from the rotating shaft and extending into the drive groove; the connecting rod is provided with a drive block and a drive device; the drive device drives the drive rod to move by driving the drive block, thereby driving the first straight cylinder to move.

[0007] In a preferred embodiment, the reset assembly includes a first fixing rod disposed on the connecting rod and a second fixing rod disposed on the fixing block; a first tension spring is provided between the first fixing rod and the second fixing rod, the first tension spring being used to pull the connecting rod so that the drive rod drives the first straight cylinder and the second straight cylinder to move, thereby causing the forming needle to extend to the corresponding position of the semi-circular groove of the preset mechanism.

[0008] In a preferred embodiment, the abutting block has a through hole coaxial with the first straight cylinder; a bushing with a perforation is inserted through the through hole, and a guide cylinder is inserted through the perforation; the end of the forming needle away from the first straight cylinder passes through the guide cylinder and extends outward.

[0009] In a preferred embodiment, the forming needle has an annular forming groove on the side away from the first straight cylinder.

[0010] In a preferred embodiment, a limiting block is provided on the side of the abutment block away from the second straight cylinder. The limiting block is used to abut against one end of the sliding hole to limit the maximum inward movement of the abutment block.

[0011] In a preferred embodiment, the fixing block has a sliding groove extending through both ends; the fixing block is provided with a baffle; the baffle is located at the side opening of the sliding groove and together with the sliding groove forms the sliding hole.

[0012] In a preferred embodiment, the baffle is provided with a hinge groove on the side away from the forming needle, and a hinge shaft passes through the hinge groove; the hinge shaft is connected to a pressure block, and a third fixing rod is provided at the end of the pressure block away from the hinge shaft; a second tension spring is provided between the second fixing rod and the third fixing rod, and the second tension spring is used to pull the pressure block to press against the baffle.

[0013] This utility model provides a chain ring forming mechanism for an integrated real rope machine. A first and second straight cylinder are stacked vertically within a sliding hole in a fixed block. A forming needle engages with a semi-circular groove in a pre-set mechanism to bend the wire. When the drive assembly moves the first straight cylinder inward, the forming needle moves away from the semi-circular groove. Simultaneously, the pressure rod of the first straight cylinder abuts against a pin through a strip-shaped sliding hole in the second straight cylinder. A compression spring provides buffering force, ensuring smooth movement and allowing the forming needle to avoid misalignment in subsequent processing steps. A reset assembly then accurately returns the first straight cylinder to its original position. Therefore, this not only improves the control precision of the forming process but also reduces wire damage through the cooperation of the compression spring and the abutment block, thereby improving forming quality and production efficiency.

[0017] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described in this specification are merely for explaining the present utility model and are not intended to limit the present utility model.

[0018] It should also be understood that the terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention. As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0019] It should also be further understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0020] In an embodiment of this utility model, a chain ring forming mechanism 100 for an integrated real rope machine is provided. This mechanism is used to bend a straight metal wire into a semi-circular chain ring by engaging a semi-circular groove of a preset mechanism on the integrated real rope machine. This facilitates subsequent chain ring clamping, hooking, welding and other processes.

[0021] like Figures 1-5 As shown, the chain ring forming mechanism 100 for the integrated real rope machine includes: a fixing block 10, a first straight cylinder 20, a second straight cylinder 30, a drive assembly 40, and a reset assembly 50.

[0022] The fixing block 10 is used to fix the machine frame of the integrated rope machine at a preset position, serving as a fixing carrier for other components. The fixing block 10 has a sliding hole 101 that allows the first straight cylinder 20 and the second straight cylinder 30 to move axially simultaneously.

[0023] The first cylindrical section 20 is a hollow, rectangular strip with a forming needle 21 at one end. The forming needle 21 engages with the semi-circular groove of a pre-set mechanism to bend the straight metal wire into a semi-circular shape. During the chain forming process, the forming needle 21 extends and is positioned above the straight metal wire. Then, the pre-set mechanism with the semi-circular groove below the metal wire moves upward, causing the metal wire to bend adaptively under the contact of the forming needle 21. The round metal wire can be flattened before bending.

[0024] The forming needle 21 has an annular forming groove 211 on the side away from the first straight cylinder 20. The bottom wall of the forming groove 211 can be cut so that the cross-section of the forming needle 21 at the corresponding part of the forming groove 211 is polygonal.

[0025] The second straight cylinder 30 is a hollow, rectangular strip, stacked vertically with the first straight cylinder 20, and both pass through the sliding hole 101. The end of the second straight cylinder 30 near the forming needle 21 has an abutment block 31 flush with the first straight cylinder 20. That is, the first straight cylinder 20 can only move inward relative to the second straight cylinder 30 (defined as the direction of movement away from the abutment block 31). Correspondingly, the abutment block 31 has a through hole 311 coaxial with the first straight cylinder 20. A bushing 312 with a perforation passes through the through hole 311, and a guide cylinder 313 with a small perforation passes through the perforation. The end of the forming needle 21 away from the first straight cylinder 20 passes through the guide cylinder 313 and extends outward, thereby preventing the forming needle 21 from being bent due to lateral pressure.

[0026] Specifically, the second straight cylinder 30 is equipped with a compression spring 32. One end of the compression spring 32 is connected to a pin 33, and the other end abuts against the inner wall of the second straight cylinder 30 at the end away from the abutment block 31. The second straight cylinder 30 is provided with a strip-shaped sliding hole 34 on the side near the first straight cylinder 20. The first straight cylinder 20 is vertically provided with a pressure rod 22 that passes through the strip-shaped sliding hole 34 and abuts against the pin 33. When the first straight cylinder 20 is driven inward by the drive assembly 40, the first straight cylinder 20 will drive the forming needle 21 to move inward relative to the second straight cylinder 30 until the pressure rod 22 abuts against one end of the strip-shaped sliding hole 34, at which point the compression spring 32 is compressed; then the first straight cylinder 20 will drive the second straight cylinder 30 to continue moving inward to achieve different action coordination during the rope chain processing. When the drive assembly 40 removes power, the compressed compression spring 32 will drive the first straight cylinder 20 to move outward and reset until one end of the first straight cylinder 20 abuts against the abutment block 31.

[0027] Furthermore, a limiting block 35 is provided on the side of the abutment block 31 away from the second straight cylinder 30. The limiting block 35 is used to abut against one end of the fixed block 10 corresponding to the sliding hole 101, so as to limit the maximum inward movement of the abutment block 31 and the second straight cylinder 30.

[0028] In an embodiment of this utility model, the driving component 40 is used to drive the first straight cylinder 20 to move inward along the sliding hole 101 so that the forming needle 21 moves away from the corresponding position of the semicircular groove of the preset mechanism.

[0029] The first straight cylinder 20 has a drive groove 201 at the end away from the forming needle 21. Specifically, the drive assembly 40 includes a connecting block 41 on the fixed block 10, a connecting rod 43 connected to the connecting block 41 via a rotating shaft 42, and a drive rod 44 located at the end of the connecting rod 43 away from the rotating shaft 42 and extending into the drive groove 201. The connecting rod 43 has a drive block 45 and a drive device (not shown in the figure). The drive device is used to open one end of the connecting rod 43 by pushing the drive block 45, and drive the first straight cylinder 20 to move away from the abutment block 31 via the drive rod 44.

[0030] The reset assembly 50 is used to return the first straight cylinder 20 to its position before being driven by the driven assembly 40. Specifically, the reset assembly 50 includes a first fixing rod 51 disposed on the connecting rod 43 and a second fixing rod 52 disposed on the fixing block 10. A first tension spring 53 is provided between the first fixing rod 51 and the second fixing rod 52. The first tension spring 53 is used to pull the connecting rod 43 so that the driving rod 44 drives the first straight cylinder 20 and the second straight cylinder 30 to move outward, thereby causing the forming needle 21 to extend to the corresponding position of the semi-circular groove of the preset mechanism.

[0031] Furthermore, in some embodiments, the fixing block 10 has a sliding groove extending through both ends. The fixing block 10 is provided with a baffle 11. The baffle 11 is located at the side opening of the sliding groove and together with the sliding groove forms a sliding hole 101. The side of the baffle 11 away from the forming needle 21 is provided with a hinge groove 12, and a hinge shaft 13 passes through the hinge groove 12. The hinge shaft 13 is connected to a long strip-shaped pressure block 14. The end of the pressure block 14 away from the hinge shaft 13 is provided with a third fixing rod 15. A second tension spring 16 is provided between the second fixing rod 52 and the third fixing rod 15. The second tension spring 16 is used to pull the pressure block 14 to press against the baffle 11.

[0032] In summary, the chain ring forming mechanism 100 for an integrated real rope machine provided by this utility model involves a first straight cylinder 20 and a second straight cylinder 30 stacked vertically within the sliding hole 101 of a fixed block. The forming needle 21 engages with the semi-circular groove of a preset mechanism to bend the wire. When the driving component 40 drives the first straight cylinder 20 to move inward, the forming needle 21 moves away from the semi-circular groove. Simultaneously, the pressure rod 22 of the first straight cylinder 20 abuts against the pin 33 through the strip-shaped sliding hole 34 of the second straight cylinder 30. The compression spring 32 provides buffering force, ensuring smooth movement and allowing the forming needle 21 to avoid displacement in subsequent processing steps. The reset component 50 accurately returns the first straight cylinder 20 to its original position. Therefore, it not only improves the control precision of the forming process but also reduces wire damage through the cooperation of the compression spring 32 and the abutment block 31, thereby improving forming quality and production efficiency.

[0033] This invention is not limited to the description in the specification and embodiments. Therefore, other advantages and modifications can be readily realized by those skilled in the art. Thus, without departing from the spirit and scope of the general concept as defined by the claims and their equivalents, this invention is not limited to the specific details, representative devices and illustrated examples shown and described herein.
