Description

Technical Field

[0001] This utility model relates to the field of bolt production technology, and in particular to a wastewater treatment device for a cold heading machine used in bolt production. Background Technology

[0002] The cold heading machine is a core piece of equipment in the bolt production process. Through a cold plastic deformation process, it efficiently processes wire into bolt blanks. Its working principle involves using internal molds and punches to apply high pressure to the metal wire at room temperature, causing the metal material to plastically flow and form within the mold cavity. This quickly completes the upsetting of the bolt head and the extrusion of the shank. The cold heading machine has a compact structure, consisting of a feeding mechanism, a mold system, a transmission system, and a control system. The feeding mechanism precisely controls the wire conveying length, the mold system uses high-hardness alloy material to ensure bolt forming accuracy, the transmission system provides stable power, and the control system enables automated operation, allowing parameters to be adjusted according to production needs. Compared to traditional hot processing, the cold heading machine has high production efficiency, significantly reduces energy consumption and material waste, and produces bolts with smooth surfaces, high dimensional accuracy, and good mechanical properties. It is widely used in the automotive, machinery manufacturing, and construction industries and is an indispensable piece of equipment for modern large-scale bolt production. To treat the wastewater generated during the operation of the cold heading machine, a wastewater treatment device for bolt production cold heading machines is required.

[0003] Currently available wastewater treatment devices for cold heading machines used in bolt production mainly consist of filtration, cleaning, and wastewater treatment units. These devices are used in automotive parts factories, machine shops, and standard parts production workshops. They purify wastewater through filtration, oil removal, and sedimentation processes, achieving water resource recycling, preventing direct discharge of wastewater and environmental pollution, and ensuring environmentally friendly production for enterprises. However, traditional grease traps or flotation machines have low removal rates of emulsified oil in cold heading machine wastewater, leading to significant difficulties in subsequent treatment. To address these issues, existing technologies only replace the wastewater with high-efficiency flotation devices, using microbubbles to adsorb and separate oil particles. A demulsifier dosing system is added before the oil removal unit to disrupt the emulsified oil structure and improve oil removal efficiency. However, the multi-step wastewater treatment structure has not been improved. This results in long-term accumulation of metal powder and oil in sand filters and precision filter elements, increasing backwashing frequency and even requiring manual disassembly and replacement of filter media, increasing consumable costs. Furthermore, maintenance shutdowns cause frequent interruptions in wastewater treatment, failing to meet usage requirements. Utility Model Content

This achieves rapid cleaning of the filter screen 5, avoids clogging of the filter screen 5, and prevents a reduction in filtration efficiency.
