Description

Technical Field

[0001] The utility model relates to an automatic feeding device, in particular to an automatic feeding device for spring heat treatment equipment. Background Art

[0002] Springs are widely used components in various machinery and equipment, and their performance directly impacts the operational stability of the entire system. To ensure springs possess good elasticity and toughness and extend their service life, heat treatment is essential. Heat treatment involves altering the internal structure and properties of metal materials through heating, insulation, and cooling processes to improve their physical properties and service life. For springs, heat treatment primarily serves the following purposes: It eliminates internal stresses. During spring processing, these stresses can degrade performance and stability. Heat treatment effectively eliminates these stresses, improving spring performance; improves the structure of the spring material, making it more uniform and dense, thereby increasing its strength and toughness; and improves stability. After heat treatment, springs become more stable and less susceptible to changes in the external environment. For example, the previously applied patent with application number 201521112929.X discloses an automatic feeding device for an automobile suspension spring tempering furnace. The springs are fed onto a feeding conveyor chain and dragged by the conveyor chain to a pneumatic positioning pushing device. At this time, the pushing cylinder is started, and the pushing cylinder pushes the rows of springs to the blocking and pushing device. After the blocking and pushing device rotates, the springs are fed into the tempering furnace. However, this requires that there are only single groups of springs on the conveyor chain, otherwise it will affect the uniform feeding of the springs. Utility Model Content

[0003] The purpose of the utility model is to provide an automatic feeding device for spring heat treatment equipment, which can improve the uniformity of spring feeding.

[0005] In the aforementioned automatic feeding device of the spring heat treatment equipment, the limiting groove is a limiting groove that is inclined upwardly toward the symmetric plane of the two groups of storage blocks.

[0006] In the aforementioned automatic feeding device of the spring heat treatment equipment, the conveyor is a belt conveyor, and the conveyor is provided with evenly distributed partitions, and the height of the partitions corresponds to the height limit plate.

DETAILED DESCRIPTION

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments, but they are not intended to limit the present invention.

[0016] Embodiment. An automatic feeding device for a spring heat treatment device, comprising: Figure 1-3As shown, it includes a frame-shaped bracket 1, and the frame-shaped bracket 1 is provided with side panels 2 on the left and right sides, and an angle iron 3 is provided on the bottom inner side of the side panel 2. A support frame 5 is provided on the upper side of the angle iron 3 through an electric push rod 4, and a blanking group 6 for spring storage and discharge is provided on the support frame 5. The blanking group 6 includes two groups of symmetrically arranged storage blocks 7, and a trapezoidal guide block 8 is provided on the inner side of the storage block 7. Inclined limit grooves 9 are provided at both ends of the storage block 7, and a limit rod 10 corresponding to the limit groove 9 is provided on the inner side of the side panel 2. A conveyor 11 is provided on the lower side of the frame-shaped bracket 1, and an evenly distributed height limit plate 12 is provided on the lower side of the angle iron 3; a discharge mechanism for realizing timed discharge is provided in the storage block 7.

[0017] The limiting grooves 9 are limiting grooves that are inclined upwardly and obliquely toward the symmetrical planes of the two groups of material storage blocks 7 .

[0018] The conveyor 11 is a belt conveyor. Evenly distributed partitions 13 are provided on the conveyor 11 . The height of the partitions 13 corresponds to the height-limiting plates 12 .

[0019] A slider 14 is provided at the lower end of the material storage block 7 .

[0020] The upper end of the support frame 5 is provided with a chute 15 corresponding to the slider 14 , and one side of the chute 15 is provided with a discharge port 20 .

[0021] The discharge mechanism includes a clamping block 17 arranged at the outer end of the guide block 8, a push rod 18 is provided in the middle of the clamping block 17, a return spring 19 connected to the clamping block 17 is provided on the outside of the push rod 18, and a cam 16 is provided at the end of the clamping block 17 to resist the clamping block 17.

[0022] Principle of the present invention: This application is primarily aimed at automatically feeding medium-to-large springs, and more specifically, at an automatic feeding device for automotive suspension springs. The springs are placed in a feed assembly 6, which consists of two storage blocks 7 and two guide blocks 8. A storage cavity for the springs is formed between the storage blocks 7, and a guide groove is formed between the guide blocks 8 to guide the springs downward. The spacing between the storage blocks 7 and the guide blocks 8 is adjustable to accommodate springs of varying sizes. To increase the spacing between the guide blocks 8, the electric push rod 4 is retracted, causing the support frame 5 to move the storage blocks 7 and guide blocks 8 downward. The support frame 5 is provided with a connecting seat, which is connected to the electric push rod via fasteners. The storage blocks 7 and guide blocks 8 are fixedly connected, using pins or screws. As the storage blocks 7 move downward, the spacing between the storage blocks 7 increases, thanks to the cooperation of the limiting rod 10 and limiting groove 9, and the slider 14 and slide groove 15, to accommodate larger springs. To reduce the spacing between the guide blocks 8, the electric push rod drives the support frame 5 upward. The discharge mechanism achieves a timed release of the springs, ensuring that a single spring is dropped each time. Furthermore, with the cooperation of the height-limiting plate 12 and the partition 13, this further ensures that only a single spring is contained within each partition space, achieving uniform spring feeding. During operation, the discharge mechanism controls the release of the springs through the cooperation of a cam 16 and a push rod 18. Driven by an external motor, the cam 16 rotates, driving the push rod outward, thereby extending the clamping block and securing the spring. As the cam 16 continues to rotate, the clamping block retracts into the guide block 8 under the action of a return spring 19, allowing the spring to be discharged.
