LGBT molding machineWhat is the principle?

The pipe end forming machine is a kind of processing and forming equipment that expands, shrinks and shrinks the pipe under normal conditions. Adopt integrated touch screen control. With the development of automobile, air conditioning and other industries, the precision of pipe end forming is getting higher and higher, especially when it comes to multi-process pipe end forming, including rotating groove, chamfering and so on. Ordinary two-position and three-position tube end forming machines cannot meet the requirements of high precision and multi-process. In view of this, a multi-station LGBT molding machine is developed, and its station conversion and punching depth adjustment are controlled by a servo system, with high precision and fast response. And an automatic loading and unloading device is added to realize automatic loading and unloading.

LGBT molding machineSuitable for machining complex tube end shapes. With three or more than three positions, can automatically change the mold, to ensure the accuracy of processing. Manual automatic arbitrary selection, CNC control, Chinese display, man-machine dialogue operation, automatic counting function. Change the mold, shrink tube, flaring can be processed, at the same time with the mold chamfer, so that the processing chamfer can be completed at one time.

Different molds can be used for expansion, contraction, shrinkage, bulge, pier reinforcement, and can be processed manually, point materials or automatically according to user requirements. It is mainly composed of fuel tank, body, slider, master cylinder, limit cylinder, compression cylinder, displacement cylinder, axial positioning cylinder and axial positioning contact iron.

By providing a pipe throttle in the master cylinder circuit, the operating speed of the master cylinder can be adjusted. The pressure cylinder circuit is provided with a superimposed hydraulic control check valve to ensure that the clamping process is not loose; a superimposed two-way throttle valve is provided on the circuit of the displacement cylinder, the limit cylinder and the axial positioning cylinder to adjust the two-way movement speed of the cylinder. Among them, the combination of the shift cylinder, the limit cylinder and the shift station can make the shift convenient and accurate, thereby ensuring the processing quality of the pipe fittings.

LGBT ShapingThe machine is widely used in the processing and forming of pipe connections, automobile oil pipes, water pipes, air conditioning pipes and other connecting parts. It is an ideal pipe end forming equipment. Manual or automatic loading and unloading are adopted, and positioning is carried out by positioning cylinder type (F scale block) (the fixed length of F scale block is connected with the end of cylinder piston rod. After the block is taken out, it is installed into clamping die to make the pipe end contact with the block, and the surface is reset after mold installation to ensure the reserved length of pipe end before molding). The workpiece is clamped by the clamping device (the clamping device is divided into upper and lower parts, the upper clamping die is connected with the piston rod of the clamping cylinder, the lower clamping die is installed on the main frame, the upper clamping die is separated from the lower clamping die, the workpiece is placed in the clamping die during operation, the oil cylinder is clamped, the upper clamping die is combined with the lower clamping die, and the workpiece is clamped.)

The machine provides the power required by the clamping cylinder, positioning cylinder, and rotating punching cylinder through an independent hydraulic station. Under the control of the electronic control system, the operation of each process of the PC is completed to realize automatic control. In this way, the metal pipe end can be processed to the desired shape, and the process of forming the pipe end can be completed by replacing the corresponding mold for different shapes.

The process of tube end forming requires different combinations of punches and dies. Different shapes need to replace different molds and corresponding clamping molds, and multiple shapes can be processed at the same time.
