Description

Technical Field

[0001] The utility model relates to the technical field of spring processing, in particular to an automatic feeding device for winding a high-strength anti-corrosion spiral spring. Background Art

[0002] A spring is a mechanical part that uses elasticity to work. A part made of elastic material deforms under the action of external force and returns to its original shape after the external force is removed. With the continuous development of society, springs are used more and more. At present, when some large springs are produced, the feeding method used is that people use a clamp to clamp the heated metal rod for manual feeding. After searching, a Chinese patent with authorization announcement number CN219817874U discloses an automatic feeding device for spring winding, including an assembly plate, a conveying seat, a clamping roller and a guide cylinder. A bidirectional motor is installed in the middle position of one side of the assembly plate, and threaded rods are installed at the output shaft ends on both sides of the bidirectional motor. The external threads of the threaded rods are connected to threaded blocks, and the top of the threaded blocks is fixedly connected to connecting blocks. The utility model has bidirectional motors installed on both sides of the assembly plate. When the bidirectional motors are started, the threaded rods on both sides can be driven to rotate, so that the threaded blocks on the threaded rods can move freely on the threaded rods, and at the same time, the threaded blocks can drive the conveying seats to move through the connecting blocks. The conveying seats on both sides of the top of the assembly plate can drive the clamping rollers to complete the rapid clamping and limiting of spring workpieces of different sizes, and the unidirectional shaft motor in the conveying seat can be started to drive the clamping rollers to rotate through the connecting gear disc.

[0003] However, in actual use, due to the lack of facilities for cutting the spring raw materials, the cut spring raw materials can only be fed one by one. Such feeding work is not only inefficient, but also cumbersome because the guide cylinder needs to be aligned each time, thereby increasing the workload.

[0004] Therefore, we made improvements on this and proposed an automatic feeding device for winding high-strength corrosion-resistant helical springs. Utility Model Content
