Description

Technical Field

[0001] The present application relates to the technical field of ring making machines, and in particular to a ring making machine. Background Art

[0002] The welding ring is a welding tool, which is made by a ring making machine. The ring making machine includes a wire feeding device, a turning tool and a guide block. The wire feeding device conveys the arc surface on the guide block of the iron wire to form a ring body, and then the turning tool shears the connection between the iron wire and the ring body. During the production process, after the turning tool shears, the formed welding ring needs to be cut. Then, the turning tool will generate stress on the ring body during shearing, causing the sheared ring body to move, thereby affecting the cutting. Utility Model Content

[0003] In order to facilitate the guidance of the welding ring, the present application provides a ring making machine.

[0004] The present application provides a ring making machine adopting the following technical solution:

[0005] A ring making machine includes a frame, a wire feeding device, a turning tool, a first driving member and a guide block. The wire feeding device, the turning tool and the guide block are distributed on the frame in sequence along the width direction of the frame. The turning tool slides in the vertical direction to connect to the frame. The first driving member is used to drive the turning tool to slide in the vertical direction. The guide block has an arc-shaped guide surface. A guide rod is provided on one side of the guide block. One end of the guide rod is located in the arc-shaped guide surface, and the other end of the guide rod extends downward.

[0006] By adopting the above technical solution, a guide rod is provided at the position of the arc-shaped guide surface. Under the action of the arc-shaped guide surface, the iron wire will form a ring and be wound around the guide rod. Then the connection between the ring wire and the iron wire is cut off by a turning tool to form a welding ring. At this time, the welding ring is sleeved on the guide rod and moves downward under the guidance of the guide rod and falls into the material receiving basket.

[0007] Optionally, the guide rod includes a first rod, a second rod and a third rod, the first rod and the third rod are arranged at an angle, the length directions of the first rod and the third rod are arranged in parallel, the second rod is used to connect the first rod and the third rod, and the length direction of the second rod is arranged horizontally.

[0008] By adopting the above technical solution, a second rod is provided in the middle of the first rod and the third rod, and the second rod is arranged horizontally. After the welding ring passes through the second rod, the second rod will buffer the welding ring, thereby reducing the falling speed of the welding ring.

[0009] Optionally, the first driving member is a servo motor, the driving shaft of the servo motor is provided with a rotating disk, a connecting rod is provided between the rotating disk and the turning tool, one end of the connecting rod is hinged to the rotating disk through the rotating rod, the rotating rod and the rotating disk are eccentrically arranged, and the other end of the connecting rod is hinged to the turning tool.

[0010] By adopting the above technical solution, the servo motor drives the rotating disk to rotate, thereby driving the connecting rod to move, and then driving the turning tool to slide up and down, so as to shorten the iron wire.

[0011] Optionally, a mounting block is provided at one end of the guide rod, the guide block is provided with a clamping groove for clamping the mounting block, and the guide block is provided with a limiting member for limiting the mounting block.

[0012] By adopting the above technical solution, a mounting block is provided on the guide rod, the mounting block can be clamped in the clamping groove, and then the mounting block is limited by the limiting piece, thereby realizing the installation of the guide rod and facilitating the replacement of the guide rod.

[0013] Optionally, the limiting member is an insertion rod, the insertion rod is slidably connected to the guide block, and a limiting hole for the insertion rod to be clamped is opened on one side of the mounting block.

[0014] By adopting the above technical solution, when installing the guide rod, the installation block on the guide rod is clamped in the black clamping operation, and then the insertion rod is slid so that the insertion rod is clamped in the limiting hole, thereby limiting the installation block.

[0015] Optionally, the guide block is provided with an elastic member for forcing the insertion rod to slide.

[0016] By adopting the above technical solution, the elastic member forces the insertion rod to slide, so that it is locked in the limiting hole, thereby improving the stability of the limit.

[0017] Optionally, the width of the guide rod in the horizontal direction is smaller than the width in the vertical direction.

[0018] By adopting the above technical solution, since one end of the guide rod is fixed and the other end is a cantilever, it is easy to deform. The width of the guide rod in the horizontal direction is set to be smaller than the width in the vertical direction, thereby reducing the possibility of deformation of the guide rod.

[0019] In summary, the present invention has the following beneficial effects:

[0020] 1. A guide rod is provided at the position of the arc-shaped guide surface. Under the action of the arc-shaped guide surface, the iron wire forms a ring and is wound around the guide rod. Then, a turning tool is used to cut the connection between the ring wire and the iron wire to form a welding ring. At this time, the welding ring is sleeved on the guide rod and moves downward under the guidance of the guide rod and falls into the receiving basket;

[0021] 2. Since one end of the guide rod is fixed and the other end is cantilevered, it is easy to deform. The width of the guide rod in the horizontal direction is set to be smaller than the width in the vertical direction, thereby reducing the possibility of deformation of the guide rod.
