Description

Technical Field

[0001] The utility model relates to the technical field of cold heading machines, and in particular to a cold heading machine for anchor bolt production. Background Art

[0002] Anchor bolts refer to the general term for all anchoring components, covering a wide range. According to different raw materials, they are divided into metal anchor bolts and non-metallic anchor bolts. According to different anchoring mechanisms, they are divided into expansion anchor bolts, expansion anchor bolts, concrete screws, nails, concrete nails, etc. Cold heading machines are special equipment mainly used for batch production of fasteners such as nuts and bolts. Existing cold heading machines include feeding mechanism, cutting mechanism, and ball upsetting mechanism. The feeding mechanism transports the steel wire to a fixed length, and then the cutting mechanism completes the fixed length cutting and sends the cut steel wire to the ball upsetting mechanism to complete the ball upsetting. The cutting mechanism retracts the knife and continues to complete cutting and feeding.

[0003] Before processing, the cold heading machine directly places the material on the feeding assembly of the cold heading machine and feeds it directly into the equipment for processing without pretreatment, or simply cleans it manually. However, due to environmental and human factors during the wire transportation process, the wire is prone to rust and bending, resulting in a large number of defective anchor bolts. The quality of the workpiece will be affected by the bending and rusting of the raw materials, resulting in poor quality of the workpiece processed by the cold heading machine. For this reason, the utility model provides a cold heading machine for anchor bolt production to solve the above problems. Utility Model Content
