Description

Technical Field

[0001] The utility model relates to a steel belt feeding mechanism of a long tail clip. Background Art

[0002] The binder clip mainly relies on the principle of metal shape recovery to generate the elasticity of the clip, thereby clamping the file and preventing it from falling off easily; most of the binder clips on the market are formed by stamping steel strips. In order to improve the efficiency of stamping, the current stamping dies are all equipped with a feeding device to achieve continuous stamping. However, the existing feeding device often applies tension to the discharge side of the stamping die, that is, the stamped steel strip is pulled and rolled up by means of a winding mechanism, thereby achieving the feeding effect. Therefore, the steel strip located on the feeding side of the stamping die is passively pulled, and the steel strip cannot always be in a flat state when being pulled. At the same time, there is a lack of necessary limit on the steel strip, which causes the steel strip to loosen easily during stamping, thereby causing the defective rate of the stamped binder clip blank to be high due to the displacement of the steel strip. In addition, the existing feeding device also lacks an adjustment function, and cannot adjust the lateral and longitudinal positions of the steel strip to the best position for mutual cooperation with the stamping die. Therefore, it is inconvenient to use and needs further improvement. Utility Model Content

[0031] Directions:

[0032] One end of the steel strip is inserted forwardly and transversely along the slope of the introduction section 811 to the bottom of the U-shaped feed trough 81 and located below each pressure plate wheel 83. During the insertion process, each pressure plate wheel 83 will roll along the upper surface of the steel strip to flatten the steel strip; then, one end of the steel strip moves forwardly from the top of the support plate 7 and passes through the flat groove 541 on the pressure beam 54 in the two clamping assemblies 5 in turn, and finally extends forward to the front of the first support plate 9; the left and right positions of the moving end of the manual slide 12 are adjusted according to the position of the stamping die, and then the left and right positions of the seat plate 1 are adjusted with the help of the moving plate 11, the back frame 13 and the lifting frame 14, thereby adjusting the left and right positions of the steel strip; then the telescopic end of the lifting cylinder 16 is driven to extend outward or retract inward to drive the seat plate 1 to move upward or downward with the help of the lifting frame 14, thereby adjusting the height of the steel strip.

[0033] The movable end of the electric slide 2 is driven to move backward to drive the two second frame plates 6 and the clamping assembly 5 located between the two second frame plates 6 to move backward to the specified position with the help of the second support plate 3; then the telescopic end of the clamping cylinder 52 in the clamping assembly 5 between the two second frame plates 6 is driven to extend outward to drive the driving block 55 in each clamping unit to move downward along each guide column 510 with the help of the lifting beam 53. When the end of the positioning plate 551 on the driving block 55 contacts the bottom surface of the positioning notch 562 on the pressing block 56, if the driving block 55 continues to move downward, it will press the pressing block 56 to move downward until the two clamping blocks 58 both press the steel strip. During this process, each spring 57 is compressed; then, the movable end of the electric slide 2 is driven to move forward to clamp the steel strip and feed it forward for a distance, so that one end of the steel strip is sent into the stamping die. At this time, the telescopic end of the clamping cylinder 52 in the clamping assembly 5 between the two first frame plates 4 remains stationary.

[0034] Next, the telescopic end of the clamping cylinder 52 in the clamping assembly 5 between the two first frame plates 4 is driven to extend outward, and then the two clamping blocks 58 on the pressing block 56 in each clamping unit are driven to press the steel belt in the same way, thereby preventing the steel belt from loosening; then the telescopic end of the clamping cylinder 52 in the clamping assembly 5 between the two second frame plates 6 is driven to retract inward to drive each clamping block 58 to move up and away from the steel belt in the same way; and then the moving end of the electric slide 2 is driven to move backward to drive the two second frame plates 6 and the clamping assembly 5 between the two second frame plates 6 to move backward again with the help of the second support plate 3 Move to the specified position; then drive the telescopic end of the clamping cylinder 52 in the clamping assembly 5 between the two second frame plates 6 to extend outward to drive each clamping block 58 to press the steel strip again in the same way, and then drive the telescopic end of the clamping cylinder 52 in the clamping assembly 5 between the two first frame plates 4 to retract inward to drive each clamping block 58 to move up and away from the steel strip in the same way; then drive the moving end of the electric slide 2 to move forward to clamp the steel strip and feed it forward again for a distance, so that one end of the steel strip is repeatedly fed into the stamping die, and finally alternate the operations according to the above steps to form a cycle.

[0035] If you want to adjust the left and right position of each clamping unit, first loosen the locking screw 512, then push it to the left or right along the lifting beam 53, and then use multiple guide columns 510 to drive the pressing block 56 to move synchronously. During this process, the two clamping blocks 58 will slide to the left or right along the two second notch grooves 542 respectively. After the adjustment is completed, tighten the locking screw 512 again.

[0036] The utility model firstly flattens the steel strip located at the feeding side of the stamping die with the help of the guide mechanism 8, and then actively feeds the steel strip from the feeding side of the stamping die into the stamping die with the help of the alternating work of the two clamping assemblies 5, and can firmly fix the steel strip during stamping to prevent it from loosening, thereby effectively reducing the defective rate of the long-tail clip blank during the stamping process; in addition, the left-right and up-and-down positions of the steel strip can be adjusted according to the position of the stamping die, thereby greatly facilitating use.
