Description

Shearing machine

The present invention relates to the field of shearing technology, and more particularly to a shearing machine for cutting a lens.

Injection molding system is a process for filling a molten molding material into a closed mold by a high pressure method to produce a product of a desired shape, which is widely used for products of ceramics, polymers, and the like with the advantages of low cost, high efficiency, high precision, and the like. For fabrication, see Leslie J. Bowen et al., Applications of Ferroelectrics, 1992. ISAF '92., Proceedings of the Eighth IEEE International Symposium on, Fabrication of piezoelectric ceramic/polymer composites by injection molding.

After the optical component has been injection molded, it also needs to be sheared to remove the runner head to obtain the desired optical component. In the prior art, the position of the gate where the flow head and the optical element intersect is usually sheared by manual shearing to remove the flow head. However, the artificial shearing staff uses the pliers to directly cut the intersection of the flow head and the optical component. Due to the shearing of the optical components, the manual operation cannot guarantee that the shear position is the same every time, possibly due to the shear position. The difference between the shape of the optical element after shearing is different, or there are differences The degree of burrs, sometimes even the phenomenon of optical components being cut.

In view of this, it is necessary to provide a shearing machine to avoid the above problems, and to quickly cut various molded products, thereby obtaining a product with a high yield.

A shearing machine will be described below by way of example.

A shearing machine includes a base, a shearing device mounted to the base, and a positioning device. The positioning device is slidably disposed on the base. The sliding direction of the positioning device is perpendicular to the shearing direction of the shearing device. The positioning device is provided with a fixing groove, and the length of the fixing groove extends parallel to the sliding direction of the positioning device for placing the product to be cut.

Compared with the prior art, the positioning device of the shearing device can slide along a shearing direction perpendicular to the shearing device, so that the shearing device can be separated according to different to-be-cut products placed in the fixing groove of the positioning device (such as symmetric distribution or The shearing of the asymmetrically distributed product to be sheared, or the product to be sheared, which is connected to the different lengths of the material, is required to adjust the relative distance between the positioning device and the cutting edge of the cutting device, thereby The product is accurately cut and is not limited by the product to be cut. At the same time, the extension direction of the fixing groove of the positioning device is perpendicular to the shearing direction of the shearing device, so that the to-be-cut product placed in the fixing groove is perpendicular to the shearing direction of the shearing device, thereby improving the cutting accuracy and avoiding shearing. Position offset.
