Description

Material cutting assembly of guide-pin-hole-free material belt cutting needle and inserting needle integrated mechanism

Technical Field

The utility model relates to a blank subassembly especially relates to a there is not blank subassembly of guide pin hole material area needle and contact pin integrative mechanism.

Background

In order to build a resource-saving and environment-friendly society, the development of circular economy and the improvement of resource utilization rate are needed. The development and the saving are repeated and the saving is prioritized, and a social resource circulation system is gradually established on the links of resource exploitation, production consumption, waste generation, consumption and the like according to the principles of reduction, reutilization and resource utilization.

Under the large trend of saving priority, the improvement of the utilization rate of resources and the reduction of the waste of the resources are important links. The unnecessary parts in the material belt of the pin are reduced, and the resource-saving society is developed.

The existing pin material belt is basically provided with a guide hole, the cutting mechanism cuts off products by positioning the guide hole, and the feeding system also takes the guide hole as a power supply point and feeds the products into the cutting mechanism by stirring the guide hole.

The needle belt cutting mechanism has the advantages that guide holes are required to be fed, qualified products cannot be accurately cut when the needle belt cutting mechanism meets a material belt without the guide holes, more waste materials are generated on the material belt due to the guide holes, and more material is wasted because the guide holes are not usually arranged in the products.

According to the overall requirements of ecological civilization construction, by the time China comprehensively builds a well-being society in 2020, great progress must be made in the construction of resource-saving and environment-friendly society. The construction of a resource-saving and environment-friendly society needs to develop circular economy and improve the utilization rate of resources. The development and the saving are repeated and the saving is prioritized, and a social resource circulation system is gradually established on the links of resource exploitation, production consumption, waste generation, consumption and the like according to the principles of reduction, reutilization and resource utilization.

The method responds to the calls of parties and countries, adheres to the principle of repeated development and saving, saves the priority, reduces the waste generated in production, improves the utilization rate of resources and can reduce the production cost at the same time. With a view to reducing the generation of waste material, the entry of unnecessary raw materials is reduced. The pin cutting process generates a plurality of scraps, which are basically guide holes and connecting sheets and are used in the production process. The guide holes in the needle belt are used for positioning the needle inserting position and feeding the driving point, but are not required parts of the needle inserting products, so that the guide hole parts become waste materials when the needle inserting products are cut off.

The existing pin belt feeding and cutting mechanism takes a guide hole in a pin belt as a reference, uses a positioning pin to position the guide hole, and then punches a pin product. If the guide hole portion is not present, an acceptable finished pin cannot be cut.

Aiming at cutting off the needle belt without the guide hole, the positioning point of the contact pin needs to be found again, and the qualified product is cut out accurately under the state that the guide hole is not used.

This non-holed needle tape cutting mechanism is a mechanism for performing precise cutting of a needle tape having no guide hole. For the transportation of the needle belt, the mechanism adopts a clamping and pushing mode, and two groups of cylinders are used for clamping, wherein one group is used for clamping the needle belt to drive the needle belt to transport, the other group is used for clamping and fixing, and the needle belt is clamped and fixed when moving in place. After the needle belt is fixed in place, the needle belt is positioned and confirmed by the ejector pin, and then the punching mechanism is used for cutting. The cutting part is that the guide needle guides the positioning point of the contact pin again, the contact pin is precisely positioned again, and then the cylinder pushes the cutting knife to cut off the contact pin connecting belt, so that a qualified contact pin product is obtained.

The existing pin inserting mode basically belongs to a material taking and inserting mode, and a material taking and transferring mechanism is needed to take the cut metal pins to an inserting position for pin inserting.
