Description

A flat head device for pipe and rod

technical field

The invention relates to a processing equipment for the end surface of a pipe and rod, in particular to a flat head device for a pipe and rod. the

Background technique

The flat end of the pipe and bar is to remove the shear marks and burrs from the end of the cut bar, and can improve the cutting accuracy of the cut to length. At present, the commonly used combined drawing machine only integrates the unwinding, straightening, drawing and fine straightening, shearing, polishing, and collection processes of the billet, and the subsequent flattening process is generally done manually, by grinding wheels or by machine. The processing lathe cuts flat ends, and the finishing quality and sizing accuracy cannot be guaranteed, and the cut and polished tubes and bars need to be transported to the machining lathe for separate cutting and flat ends by driving. Therefore, the production labor intensity is high, the operation rate is low, and it cannot be effectively matched with the production rhythm, and it is easy to cause a backlog of drawn tubes and bars. the

After investigation, the existing Chinese patent No. CN200920231295.8 "A fully automatic stainless steel flat head machine" includes a machine base, a machine frame set on the machine base, and a clamp capable of clamping bars on the machine base. , a transmission mechanism is provided at one end of the clamp, and it is characterized in that a flat head device installed on the frame is arranged above the clamp, a lifting and feeding mechanism is connected to the clamp, and a sensor is arranged between the flat head device and the clamp. The above-mentioned clamps, lifting and feeding mechanism, flat head device and sensor are all connected with the control system, and the sensor can send a signal to the control system when the flat head device cuts off the bar. There is also the Chinese patent "a pipe fitting flat head machine" with the patent number CN200920118973.X, which includes a stand, a power device arranged in the stand, a transmission device and a flat head device, and the power device is linked with the flat head device through a transmission device. The device includes a processing transmission mechanism and a cam transmission mechanism, and the flat head device is arranged on the platform surface of the platform, including the cam mechanism and the processing mechanism. The flat head machine adopts the cam transmission mechanism to automatically control the feed, and uses the pneumatic synchronous switch to control the cylinder to drive the workpiece clamping seat to realize the automatic clamping of the workpiece. The feeding process is completed manually, with higher production efficiency and higher precision. The above-mentioned two flat-head machines have improved the degree of automation and are relatively time-saving and labor-saving, but they cannot be combined with the drawing machine for online continuous operation, and manual feeding is required, which cannot well meet the requirements of continuous mass production. the
