Metal Processing Equipment Manufacturer for Peeling, Grinding, Cutting and Pickling Lines

Double-bar dual-end Chamfering&facing and double-end chip removal device and conveying rack are all installed on the same body. The bar material is loaded to the left end facing device or the right end facing device through the dialing device on the roller table alternately. Two bars roll and slide into the double-station positioning V-groove. There are pulleys under the inner side of the V-groove. The cylinder pushes the bar on the pulley to the positioning block. The press cylinder on the double-facing device head drives the double V-shape holder to clamp the bar. Driven by the oil cylinder,the facing tool process the end surface.The left and right double facing devices process alternately. The jacking cylinder mechanism lifts the bar and convey the bar for the next double chamfering process (double pre-positioned V groove). The bar material was lifted and  slides down from the double pre-position slot to (the right ,the double-end chamfering v-groove), and the bar is pushed by the cylinder again to the right side of the double chamfering head. There is a positioning block in front of the head (pneumatic lifting block), the bar stops where the block positions, the block is lifted, and the pressure cylinder on the double chamfering head drives the double V-shaped clamp to clamp the right end of the bar and the double chamfering head begins the chamfering process. The bar material slides from the double chamfering V-groove on the right end and slides into the double chamfering V-groove on the left end, and pushes the bar on the pulley to the left double-chamfering head by the cylinder again. The left and right double-head chamfering is also processing alternately and repeatedly. The right machine head is fixed, the left head and the conveying rack are driven by hydraulic cylinders, which can be adjusted according to different bar materials, and the length of the bar to be processed can be adjusted on the operating table. Milled and chamfered products have no burrs and are smooth and flat. The milling depth of the end face can be adjusted from 3 to 5mm, and the chamfer size is 2 ~ 3 × 45 ° mm. The depth of the milling surface and the chamfer can be adjusted according to the actual situation of the incoming material. It is required that no new bending deformation should be caused to the bar during the processing.

The working stand of roll mill is usually composed of roller, roller bearing, frame, rail support, roller adjustment device, up roller balance device and roller changing device. And other series of auxiliary processing equipment during rolling such as raw material preparation, heating, steel turning over , shearing, straightening, cooling, crack detection, heat treatment and pickling equipment. The type and size of finished or semi-finished rolling mill selection should be decided according to the machine variety, specification, quality and quantity, and with the consideration of necessary auxiliary, lifting transport and ancillary equipment. Finally the decision can be made referring to various kinds of factors to achieve a balanced choice.

The main structure of LG cold tube rolling mill is composed of machine bed, rotary feeding mechanism, frame, a main motor, core rod, transmission system, electrical system, etc. With the development of technology, nowadays the rotary feeding mechanism has been evolved into single rotation, double feeding, double rotation, single feeding in,and double rotation double feeding in. And the usual feeding mode can be divided into mechanical feeding, photoelectric feeding, and servo feeding. The most critical part of one cold rolling mill is the frame, which includes roller, gear, rack, etc.. The working principle can be described as follows. By creating regular cavity by roller and mandrel, steel tube can be rolling milled taking advantage of elastic deformation of metal. The cold tube rolling mill machine can achieve cold rolling process to the shell using ring hole with relatively good first time rolling performance, and can process nonferrous metal seamless pipe of normal precision as well. The most obvious characteristic of cold mill is the high material utilization, with better precision and surface roughness than cold tube drawing machine.

The WHS-450×4000 honing machine adopts a horizontal frame-type structure. Its main components include machine bed, spindle head, guide rails, honing bar rotary drive motor, honing expansion drive motor, spindle head traverse drive motor, honing head, honing bar, workpiece fixing V-block, electrical cabinet, operation box, coolant tank and coolant pump, together with an assembled magnetic filter.

The HC35X3M CNC deep-hole honing machine supports constant-pressure honing with simple and convenient operation. Adopting a workpiece-fixed structural design, the equipment realizes honing processing through the rotation and reciprocating linear motion of the honing head. It is specially designed for honing and polishing cylindrical deep-hole workpieces, widely applicable to precision tubular parts such as hydraulic cylinders and pneumatic cylinders. The machine achieves a machining accuracy of IT6–IT7 or higher for bore diameters, with the surface roughness reaching Ra 0.2–Ra 0.4 after polishing. The localized honing function effectively corrects workpiece machining errors including taper, ovality and partial aperture deviation. It can directly perform honing on cold-drawn steel tubes, serving as an ideal high-precision and high-efficiency deep-hole finishing equipment. Equipped with a professional PLC control system, the machine features stable commutation and flexible speed regulation during operation. It ensures consistent bore dimensional accuracy while greatly reducing labor intensity. The system stably controls the expansion dimension of the honing head throughout the honing process, guaranteeing uniform bore diameter precision and significantly improving deep-hole honing efficiency. The honing head adopts a servo motor matched with a reducer for constant-pressure expansion, delivering stable and constant honing force from the abrasive strips to ensure excellent roundness and cylindricity of workpieces. The honing rod is equipped with universal joints at both ends, which effectively guarantee the straightness of machining and overall equipment stability. The honing pressure is adjustable to meet diverse processing requirements. The machine’s machining diameter range is Φ50–Φ350 mm. Featuring easy operation, high production efficiency and superior economic benefits, this equipment is adaptable to both mass production and single-piece & small-batch processing scenarios, making it an optimal choice for deep-hole precision finishing.
