Description

Technical Field

[0001] The utility model relates to a spring production device. Background Art

[0002] A spring production device refers to mechanical equipment specifically used to produce spring products, and the spring coiling device therein is a device specifically used to wind a spring straight line into a coiled spring according to the required size. The spring coiling device generally includes a spring linear transmission device, a spring linear correction wheel device, a spring directional column device connected to the output end of the spring linear transmission device, a curve gauge device and a cutter device. In the actual production process of the existing spring coiling device, it is found that the newly produced spring straight lines have poor straightness and large distortion. When they are trimmed by the spring linear correction wheel device, they are prone to jamming at the spring linear correction wheel device, affecting the overall production efficiency. In addition, due to the excessively large amplitude of the spring straight line, it is easy to cause frequent impacts on the spring linear correction wheel, resulting in a shorter service life. Improvements and optimizations are made in this regard. Utility Model Content

[0019] A guide partition plate 22 is provided between the two buffer blocks 16 in the buffer seat through hole 20, so that the buffer block 16 can move more accurately and smoothly when the position of the main shaft 10 changes.

[0020] The buffer block 16 is made of rubber to reduce the wear on the main shaft 10 when it contacts the upper end of the main shaft 10 .

[0021] The buffer seat through hole 20 is a square structure, and the number of the buffer blocks 16 is 4, which can take into account the four directions of front, back, left, and right, and has a better buffering effect.

[0022] The transition correction bracket 8 is provided with a lower bracket mounting portion 24 for mounting and fixing the motor 9, and an upper bracket mounting portion 25 provided above the lower bracket mounting portion 24 and for mounting and fixing the buffer seat 15.

[0023] The bottom of the buffer seat 15 is provided with a buffer seat limiting protrusion 28, and the bracket upper mounting portion 25 is provided with a bracket upper limit opening 29 corresponding to the buffer seat limiting protrusion 28, so that the limiting is accurate and the buffer seat 15 is installed firmly and tightly.

[0024] Working process: the spring straight line is transmitted to the transition correction device 6 via the spring wire transmission device 1. Since the straightness of the spring straight line is poor, when the spring straight line is initially corrected by the transition correction wheel 12, the spring straight line causes an impact on the transition correction wheel 12, so that the transition correction wheel 12 transmits the impact to the main shaft 10. The main shaft 10 can swing slightly freely due to the action of the universal joint 11, and the upper end of the main shaft 10 shifts accordingly. Under the action of the buffer block 16 and the return spring 18, the impact from the main shaft 10 can be quickly removed and the main shaft 10 can be quickly returned. On the one hand, the transition correction wheel 12 can self-adjust the spacing when it is subjected to a large impact, thereby not causing jamming during the transmission process. On the other hand, the buffer block 16 and the return spring 18 can make a preliminary correction to the straightness of the spring straight line at a relatively fast speed, thereby reducing the jamming and impact problems caused to it after it enters the spring straight line correction wheel device 2, thereby effectively improving the overall production efficiency.
