Description

Technical Field

[0001] The present application relates to the technical field of sleeve nut assembly, and in particular to a sleeve nut stamping device. Background Art

[0002] In the sleeve nut fixing structure, there is a semicircular groove on the outer wall of the sleeve and the inner wall of the nut. The two semicircular grooves are clamped together to form a circular groove for the steel wire to pass through; the nut is penetrated by an insertion hole communicating with the circular groove for the steel wire to enter; when the steel wire is inserted into the circular groove, the nut and the sleeve are relatively fixed in the axial direction and can rotate relative to each other in the circumferential direction.

[0003] In the existing technology of threading the wire through the sleeve nut, it is done manually by the operator. Due to the different proficiency of the operators, the work efficiency is low during the mass production process.

[0004] With respect to the above-mentioned related technologies, the inventor believes that manual operation results in a long time for threading the steel wire, low efficiency, prolonged production time and increased production costs. Utility Model Content

A stamping rod that can be abutted against a steel wire is fixedly arranged in the mounting tube; an auxiliary tube for inserting the stamping rod is slidably arranged in the mounting tube.

[0008] By adopting the above technical solution, the steel wire passed through the nut sleeve is manually aligned with the auxiliary tube during use, and the first driving member pushes the punching rod downward so that the steel wire in the auxiliary tube is continuously inserted along the insertion hole and the circular groove, and entangled in the sleeve nut, thereby improving production efficiency.

[0009] Furthermore, a fixing block is provided on the workbench, and a fixing groove is provided on the upper surface of the fixing block to fit with the outer surface of the nut.

[0010] By adopting the above technical solution, the fixing groove can fully fit the nut, so that the nut sleeve is not easy to slide during the stamping process, and a certain fixing effect is achieved.

[0011] Furthermore, the workbench is provided with fastening screws on both sides of the fixed block, and each of the fastening screws is threadedly connected to a fastening nut that can abut against the upper surface of the fixed block.

[0012] By adopting the above technical solution, the fastening nut and the fixing block are abutted against each other, thereby fixing the fixing block well.

[0013] Furthermore, a pressing plate is provided on the upper surface of the fixing block, and a mounting hole for inserting a fastening screw is provided through the pressing plate, and the fastening nut is pressed against the upper surface of the fixing block through the pressing plate.

[0014] By adopting the above technical solution, the pressing plate is connected to the fixing block, the abutting area is increased, and thus a better fixing effect is achieved.

[0015] Furthermore, a support block is provided on the upper surface of the workbench, and the lower surfaces of both ends of the pressing plate are respectively against the fixed block and the support block.

[0016] By adopting the above technical solution, the pressing plate connects the fixed block and the workbench, which can prevent the entire fixed block from sliding, thereby making the fixed block more stable.

[0017] Furthermore, a positioning block is provided at one end of the fixing block located in the fixing slot.

[0018] By adopting the above technical solution, the positioning block performs axial positioning on the nut sleeve, so that the nut sleeve is better fixed.

[0019] Furthermore, a fixing convex ring is provided on the inner side wall of the mounting tube and at the lower end thereof, and a fixing piece is provided on the outer side wall of the auxiliary tube and at the upper end thereof.

[0020] By adopting the above technical solution, the fixing protrusion at the lower end of the inner wall of the mounting tube and the fixing piece at the upper end of the outer wall of the auxiliary tube can make the auxiliary tube slide in the mounting tube without falling.

[0021] Furthermore, a tapered guide surface is provided on the inner side wall of the auxiliary tube and below the auxiliary tube.

[0022] By adopting the above technical solution, the opening of the tapered guide surface is larger than the ordinary circular opening area, making it easier for the auxiliary tube to be inserted into the steel wire.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. During use, manually align the steel wire on the nut sleeve with the auxiliary tube. The first driving member pushes the punch rod downward so that the steel wire in the auxiliary tube is continuously inserted along the insertion hole and the circular groove and twisted into the sleeve nut, thereby improving production efficiency.

[0025] 2. Connecting the workbench and the fixed block by pressing the plate can prevent the fixed block from sliding and increase the stability of the fixed block;

[0026] 3. By setting a tapered guide surface at the bottom of the inner wall of the auxiliary tube, the opening area can be increased, making it easier for the auxiliary tube to be inserted into the steel wire for subsequent operations. BRIEF DESCRIPTION OF THE DRAWINGS
