Description

Technical Field

[0001] This invention relates to the field of chain braiding machine technology, and in particular to a highly efficient and convenient chain braiding machine and chain braiding method. Background Technology

[0002] Metal chains are made up of interlocking metal rings, which are formed by cutting, bending, and shaping long strips of wire. During processing, they generally need to be chained first, then welded and deburred. However, existing chain weaving mechanisms are either too complex to be easily maintained or not stable enough, especially in the processing of some heavy chains, where it is difficult to guarantee the stability of the processing. Summary of the Invention

[0003] The purpose of this invention is to provide an efficient and convenient chain braiding machine and chain braiding method, which can improve the stability of chain braiding, and has a simple structure that facilitates maintenance.

[0004] The above-mentioned technical objective of the present invention is achieved through the following technical solution: A high-efficiency and convenient chain braiding machine includes a forming component and a feeding component. The forming component includes a forming mold and a pressing mold. The pressing mold presses the raw material strip into chain links along the forming mold. The forming mold is telescopic and has a notch at its lower end. The feeding component includes a feeding cylinder located below the forming component and a rotating drive component that drives the feeding cylinder to rotate. The feeding cylinder has a lifting and lowering abutment plate. The abutment plate has a cross-shaped receiving groove for the chain links to be placed horizontally. The center of the cross-shaped receiving groove also has a through hole for the chain links to pass through vertically. The moving path of the abutment plate includes a forming position and a passing position. When the abutment plate moves upward to the forming position, the uppermost horizontal chain link enters the notch of the forming mold. When the abutment plate moves downward to the passing position, the uppermost horizontal chain link rotates to the vertical position under its own weight, allowing it to pass through the through hole.

[0005] Furthermore, the rotation drive includes a rack and a cylinder, the output end of the cylinder is connected to the rack and drives the rack to move linearly, and the outer periphery of the feed cylinder is provided with teeth that mesh with the rack.

[0006] Furthermore, the molding die is provided with fixing blocks at both ends. When the molding die retracts inward, the fixing blocks push the chain links outside the molding die to separate from the molding die.

[0007] Furthermore, the notch in the forming mold is larger than the cross-section of the chain link.

[0008] Furthermore, the notch of the molding die is also provided with an inwardly increasing clearance groove.

[0009] Furthermore, the feeding cylinder is equipped with two drive cylinders or electric cylinders that drive the abutment plates to move up and down.

[0010] Furthermore, it also includes a feeding assembly, which includes a feeding block on one side and an alignment block on the other side. The feeding block has a feeding hole, through which raw material strips are conveyed and conveyed to one end to abut against the alignment block.

[0011] Furthermore, the molding component includes an upper molding die and two symmetrically arranged horizontal molding dies. The upper molding die presses the middle part of the raw material strip along the upper side of the molding die, and the two horizontal molding dies press the two ends of the raw material strip along the lower side of the molding die.

[0012] A chain weaving method includes the following steps: a raw material strip is conveyed to the top of a forming mold; a pressing mold presses the raw material strip into chain links along the forming mold; then a retaining plate moves upward to the forming position; the forming mold retracts inward, so that the processed chain links are placed horizontally downward in the retaining plate; the feed cylinder rotates 90 degrees, and the forming mold extends outward, so that the upper part of the horizontal chain links enters the notch of the forming mold. The next raw material strip is fed to the top of the forming mold. The pressing mold presses the raw material strip into a chain link along the forming mold. Then, the abutment plate moves downward to the ring-passing position. The uppermost horizontal chain link rotates to the vertical position under its own weight and passes through the through hole of the abutment plate. Then the abutment plate moves upward to the forming position. The forming mold retracts inward, so that the second processed chain link is placed horizontally downward in the abutment plate. The feed cylinder rotates 90 degrees, and the forming mold extends outward, so that the upper part of the horizontal chain link enters the notch of the forming mold. Repeat the above steps to complete the chaining process.

[0013] Furthermore, during the chain weaving process, the formed chain first hangs on a fixed surface for a certain length before being conveyed away.

[0014] In summary, the present invention has the following beneficial effects: The raw material strip is pressed into chain links along the forming mold by the pressing mold. The abutment plate moves downward to the ring-passing position. The uppermost horizontal chain link rotates to the vertical position under its own weight and passes through the through hole of the abutment plate. Then the abutment plate moves upward to the forming position. The forming mold retracts, so that the second processed chain link is placed horizontally downward in the abutment plate. The feed cylinder rotates to realize the next chain weaving, which improves the stability of chain weaving. Moreover, its structure is simple and convenient for maintenance.

Detailed Implementation

[0017] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. These embodiments do not constitute a limitation of the present invention. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this application.

[0018] A highly efficient and convenient chain braiding machine, such as Figure 1 As shown, it includes a feeding component, a forming component, and a discharging component. The feeding component includes a feeding block 7 on one side and an alignment block 71 on the other side. The feeding block 7 is provided with a feeding hole, through which raw material strips are conveyed and conveyed to one end of the raw material strips abutting against the alignment block 71. The raw material strips can be pre-cut and then conveyed into the feeding block 7, or they can be obtained by cutting and feeding while weaving the chain.

[0019] like Figure 1 As shown, the forming component includes a forming mold 1 and a pressing component. The pressing component presses the raw material strip into a chain link along the forming mold 1. In this embodiment, the pressing component includes an upper pressing mold 2 and two symmetrically arranged horizontal pressing molds 3. The upper pressing mold 2 is located above the forming mold 1 (the feeding component is located between the two, conveying the raw material strip to the upper part of the forming mold 1). It moves up and down through a hydraulic cylinder or cam structure, pressing the middle part of the raw material strip downward along the upper side of the forming mold 1. The two horizontal pressing molds 3 are located on both sides below the forming mold 1. They move closer or further apart through a hydraulic rod or screw drive structure, pressing the two ends of the raw material strip inward along the lower side of the forming mold 1. The more structural principles are existing technologies and will not be described in detail here.

[0020] like Figure 1 As shown, the forming mold 1 is telescopically oriented and has a notch at its lower end. In this embodiment, the notch of the forming mold 1 is larger than the cross-section of the chain link. To facilitate the flipping of the chain link within the notch, the notch of the forming mold 1 can be further configured as an inwardly opening clearance groove with a gradually increasing cross-section. The forming mold 1 can be telescopically oriented in the inward and outward directions by a horizontal cylinder in the frame, stably realizing the connection between the chain links and the separation of the chain links from the forming mold 1. In some embodiments, the frame is also fixed with fixing blocks 11 located at both ends of the forming mold 1. When the forming mold 1 retracts inward, the fixing blocks 11 push the chain links outside the forming mold 1 to separate from the forming mold 1. The feeding assembly includes a feeding cylinder 4 located below the forming mold 1 and a rotation drive component that drives the feeding cylinder 4 to rotate around a vertical axis. The rotation drive component includes a rack 6 and a cylinder 61. The output end of the cylinder 61 is connected to the rack 6 and drives the rack 6 to move linearly. The outer periphery of the feeding cylinder 4 is fixed with teeth that mesh with the rack 6 to realize the rotation of the feeding cylinder 4. In this embodiment, its rotation angle is 90 degrees for reciprocating.

[0021] like Figure 1 and Figure 2 As shown, the feeding cylinder 4 is equipped with a lifting and lowering abutment plate 5. Two driving cylinders 61 or electric cylinders are fixed inside the feeding cylinder 4 to drive the abutment plate 5 to move up and down. The abutment plate 5 is provided with a cross-shaped receiving groove 51, in which the chain link is placed horizontally. The center of the cross-shaped receiving groove 51 is also provided with a through hole 52 for the chain link to pass through vertically. The moving path of the abutment plate 5 includes the support position, the forming position, and the loop position. The support position is located at the top. When the abutment plate 5 moves upward to the support position, the cross receiving groove 51 in the abutment plate 5 abuts against the lower part of the corresponding chain link (or at a certain distance, waiting for the chain link to fall into it under its own weight), waiting for the forming mold 1 to retract and separate, so as to achieve stable horizontal placement of the chain link. When the forming position is in the middle position, the abutment plate 5 moves upward to the forming position, and the upper part of the uppermost horizontal chain link enters the notch of the forming mold 1, waiting for the new chain link to be processed and formed. When the abutment plate 5 moves downward to the abutment position, the uppermost horizontal chain link rotates to the vertical position under its own weight, allowing it to pass through the through hole 52. Then the abutment plate 5 moves upward to place the processed chain link, making it the new uppermost horizontal chain link.

[0022] This embodiment also discloses a chaining method, including the following steps: The raw material strip is conveyed to the top of the forming mold 1. The pressing mold presses the raw material strip into a chain link along the forming mold 1. Then the abutment plate 5 moves upward to the support position (or forming position). The forming mold 1 retracts inward, so that the processed chain link is placed horizontally downward in the abutment plate 5. Then the abutment plate 5 moves to the forming position, the feed cylinder 4 rotates 90 degrees, and the forming mold 1 extends outward, so that the upper part of the transverse chain link enters the notch of the forming mold 1. The next raw material strip is fed to the top of the forming mold 1. The pressing component presses the raw material strip into a chain link along the forming mold 1. Then, the abutment plate 5 moves downward to the ring-passing position. The uppermost horizontal chain link rotates to the vertical position under its own weight. The abutment plate 5 rises and allows the vertical chain link to pass through the through hole 52 of the abutment plate 5. Then, the abutment plate 5 moves upward to the support position (or forming position). The forming mold 1 retracts inward, so that the second processed chain link is placed horizontally downward in the abutment plate 5. Then, the abutment plate 5 moves to the forming position, the feed cylinder 4 rotates 90 degrees, and the forming mold 1 extends outward, so that the upper part of the horizontal chain link enters the notch of the forming mold 1, waiting for the next chain link to be processed and formed. Repeat the above steps to complete the chaining process; In order to reduce the pressure on the feed cylinder 4, for heavy chains, during the chain weaving process, the formed chain is first dropped to a fixed surface (ground) for a certain length, and then conveyed upwards and away by subsequent conveying equipment.

[0023] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art can make various modifications or equivalent substitutions to the present invention within the scope of its essence and protection. Such modifications or equivalent substitutions should also be considered to fall within the protection scope of the present invention.
