Description

[0002] A progressive die is a set of stamping processes that complete the stamping of a part. These processes are arranged within the same die set. The metal material used in progressive dies is in coil form, and a feeder delivers the material at equal intervals to each independent stamping process within the die. The processing steps in a progressive die include blanking, cutting, trimming, tongue trimming, parting, flaring, punching, and notching. Generally, the area containing the material within the die, along with the section connecting the semi-finished products of each process to the finished product, is collectively referred to as the strip.

Therefore, after the strip is cut and its required functionality is achieved on subsequent automated equipment, a structure is often needed to remove the scrap material. As shown in patent document CN 113843339 A, traditional scrap removal structures are often large in overall size, have low work efficiency, insufficient stability, and are prone to deformation of the product itself, in addition to the scrap material.

[0030] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0031] The terms "first," "second," "third," "fourth," etc., used in the specification and claims of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0032] First embodiment.

[0033] Please see Figures 1-3 The first embodiment of the present invention provides a strip separation device, including a frame 1 and a drive device 2 and a separation mechanism 3 mounted on the frame 1. The separation mechanism 3 includes a separation mounting plate 31 and a plurality of spaced torsion members 32. The torsion members 32 are rotatably mounted on the separation mounting plate 31. The ends of the torsion members 32 are provided with clamping portions 321 for clamping the strip. The drive device 2 is used to cause the strip to bend in multiple places when the clamping portions 321 clamp the strip, thereby breaking the connection between the strip and the workpiece.

[0034] The above configuration, through the drive device 2 driving multiple torsion members 32 to rotate simultaneously in both forward and reverse directions, causes the clamping part 321 to cause the material strip to bend in multiple places, creating an action similar to manually prying the workpiece out of the material strip. This causes the connection between the workpiece and the material strip to break and fall off, thereby achieving the purpose of separating the workpiece from the material strip. This allows for efficient and automated separation of the workpiece from the material strip. In practical use, the number of torsion members 32 can be adjusted according to the size of the workpiece or the actual condition of the material strip to improve work efficiency. The spacing between the torsion members 32 corresponds to the size of the workpiece in the material strip, so as to better separate the workpiece from the material strip.

[0035] Specifically, please refer to Figure 3 and Figure 5 The separation mechanism 3 further includes a separation base plate 33, and the separation mounting plate 31 is mounted on the separation base plate 33. In this embodiment, there are two separation mounting plates 31, which are spaced apart from each other.

The guide rail 281 is installed on the lower side of the upper cover plate 272, and the guide slider 282 is fixedly installed on the upper side of the sliding cover plate 26.

[0044] With the above configuration, when the reciprocating drive is activated, the transmission mechanism drives the rack 251 to reciprocate.
