Description

Clamping and pulling mechanism of large-specification sleeve manufacturing equipment

Technical Field

The utility model belongs to the technical field of chain accessory processing apparatus, especially, relate to a card of big specification sleeve preparation equipment draws mechanism.

Background

The prior processing of the sleeve adopts uniform equipment. However, in actual production the sleeves have many sizes, some smaller and some larger. When the existing processing equipment needs to process and feed materials, one end of a round steel is pulled out of a coil, and then the round steel head penetrates through a guide wheel and enters the processing equipment for butt joint by manpower. The processing equipment is suitable for processing the small-sized sleeve. But is disadvantageous for large format sleeve tooling. The round steel of the big specification that the sleeve of big specification adopted, the round steel weight of big specification itself is great, and when the manual work pull out round steel head and push into equipment through the leading wheel and dock, can receive the influence of its weight and hardly push into equipment the round steel head. Thereby causing the need for multiple persons to perform auxiliary operations and causing processing troubles.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to solve above the technical problem provide one kind can be when the sleeve machine-shaping of big specification, the round steel is pulled out the back from the coil, can laborsaving, simple and convenient, automatic push the card of the big specification sleeve preparation equipment that carries out the butt joint in the processing equipment and draw the mechanism, its technical scheme as follows:
