Abstract
Description
Technical Field
[0001] This utility model relates to the field of metal sheet breaking technology, and in particular to a material strip single-sided feeding limit floating device and a metal sheet breaking device. Background Technology
[0002] With the rapid development of industries such as 3C electronics and precision machining, increasingly higher demands are being placed on the shape complexity, dimensional accuracy, and production efficiency of metal sheet components. In modern stamping production, metal sheets are typically transported and processed in the form of continuous strips. Multiple metal sheet units are retained on the strip substrate through micro-connection points, forming the basis for efficient and automated production. Traditional processing methods rely on a double-sided clamping float device: the two edges of the strip are respectively confined in two precision slit guide rails, and the strip is driven to advance step by step along a predetermined path by float blocks. After each feeding step, the stamping die performs a punching, forming, or separating operation, thereby completing the processing of the metal sheets one by one.
[0003] However, as product designs trend towards miniaturization and irregular shapes, a large number of asymmetrical strip structures have emerged. In such strips, often only one side has a complete and continuous edge structure for clamping, while the other side consists of multiple metal sheet units to be separated, lacking continuous and stable clamping conditions. This structural feature of clamping on one side and suspending on the other side makes traditional double-sided floating clamping mechanisms completely unsuitable. If the traditional method is forcibly used, it will not only fail to effectively constrain the movement of the strip, leading to unstable feeding and poor positioning accuracy, but may also cause strip twisting, vibration, or sheet deformation during stamping, seriously affecting product dimensional consistency and even causing problems such as increased scrap rate and mold damage.
[0004] Therefore, for this special strip material that can only be clamped on one side, there is an urgent need to develop a new strip material feeding limit floating device and a metal sheet breaking device. This device can reliably clamp the edge on one side while effectively guiding the strip material to feed stably, and ensure that the strip material will not deviate or shake during the stamping and breaking of the metal sheet, thereby ensuring processing accuracy and production continuity.

[0036] Specifically, referring to Figures 1 to 7, the thickness H of the material strip 1 is 0.15mm-1.5mm, the depth of the convex hull 3 is 1.5H, the width of the groove body 213 is 1.5H, the depth of the groove body 213 is greater than the depth of the convex hull 3, the distance L between the convex hull 3 and the edge of the material strip 1 is 2mm-5mm, the first edge 11 of the material strip 1 is constrained by the slit formed by the bottom surface 221 and the avoidance portion 212. When the material strip 1 advances in a floating manner, in the left-right direction, the first edge 11 is constrained by the convex hull 3 and the groove body 213, so that the first edge 11 advances along the groove body 213, which improves the advancing stability of the single-sided material strip 1, ensures that the first edge 11 is clamped, constrained and movable, the second edge 12 of the material strip 1 is suspended, and a plurality of metal sheets 4 to be broken are exposed outside the avoidance portion 212.

[0038] Through this embodiment, by providing the groove body 213 in the avoidance portion 212, the groove body 213 limits the left-right displacement of the material strip 1 in the left-right direction through the convex hull 3, which ensures that the material strip 1 with only the first edge 11 constrained will not generate left-right displacement during advancing, and provides a basis for accurately breaking the metal sheets 4.
