Description

Technical Field

[0001] The utility model belongs to the technical field of spring bar material processing equipment, and in particular relates to a feeding mechanism for suspension spring bar material. Background Art

[0027] A guide plate 14 is horizontally installed on the side surface of the first side plate 61.

The guide plate 14 is used to assist in supporting the bar material to ensure the smooth operation of the bar material.

[0028] The specific working process of the utility model is as follows: A plurality of rollers 16 are arranged in the bar material conveying system 15. The spring bar material is conveyed to a position close to the fixed fixture through the plurality of rollers 16. Under the action of the crank and connecting rod of the power driving box 17, the lever 18 placed at the bottom of the spring bar material lifts the spring bar material. The power driving box 17 continues to operate, and the lever 18 pushes the spring bar material into the support groove 19. An auxiliary roller is arranged on one side of the support groove 19, and the spring bar material presses on the auxiliary roller and runs more smoothly. The spring bar material is placed between the movable clamping plate 64 and the fixed clamping plate 65. The cylinder rod of the first clamping cylinder 63 extends outwards, and the distance between the movable clamping plate 64 and the fixed clamping plate 65 decreases and clamps the spring bar material. The bar material is supported by the guide plate 14. The cylinder rod of the auxiliary cylinder 11 extends outwards, and the third movable pressure block 13 presses down on the spring bar material. The cylinder rod of the driving cylinder 9 extends outwards, and the clamping bracket 6 moves towards the coiling device. The spring bar material passes through the gap between the first movable clamping block 85 and the second movable clamping block 88. The cylinder rods of the second clamping cylinder 83 and the third clamping cylinder 86 both extend outwards. The spring bar material is placed between the first movable clamping block 85 and the second movable clamping block 88. The coiling device clamps the head of the spring bar material and performs coiling. The spring bar material runs stably without vertical and horizontal crosstalk. During this process, the movable clamping plate 64 and the fixed clamping plate 65 do not clamp the spring bar material to death. The movable clamping plate 64 and the fixed clamping plate 65 only play a limiting role. The spring bar material can move linearly along its axial direction. During the whole process, the spring bar material can linearly enter the coiling device to complete the spring coiling.

[0029] After a spring bar stock is coiled, under the action of the crank and connecting rod of the power drive box 17, the lever 18 placed at the bottom of the spring bar stock resets, the cylinder rod of the first clamping cylinder 63 retracts, the distance between the movable clamping plate 64 and the fixed clamping plate 65 increases, the cylinder rods of the second clamping cylinder 83 and the third clamping cylinder 86 both retract, the gap between the first movable clamping block 85 and the second movable clamping block 88 increases, the cylinder rod of the auxiliary cylinder 11 retracts, and the third movable pressing block 13 is lifted. All of the above operations are for the entry of the next spring bar stock.

[0030] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of the present invention.
