| The company's introduction to elbow pushing machine
Operation of elbow push-making machine: after the pipe billet is placed in the mold, the upper mold and the lower mold are combined to press the elbow, and the elbow is made into a type by pushing the push rod. In order to prevent the wrinkled defects of the produced elbow, the general pipe will be injected with liquid medium along the gap between the inner and outer mold, that is, tap water.
The working principle of elbow pushing machine: the press is used to directly press and form in the die. Before stamping, the tube billet is placed on the lower die, and the inner core and end die are loaded into the tube billet. The upper die moves downward to press, and the elbow is formed through the constraint of the outer die and the support of the inner die.Welding elbow rule is to use the mold to press out two pipe elbow half shell, and then weld into the elbow method, this method has many subsequent processes, and the welding manufacturing technology of large thin-wall elbow is poor.
Elbow push system of machine producing bend features: beautiful appearance, uniform wall thickness will be a lot of, meet the requirements of customers, improve the economic benefit, production method is simple in operation process, high production efficiency, low cost, high precision products, polishing, small amount of work workers labor intensity is not big, cutting loss, elbow machining allowance is small, product quality is good, but is expected to open complex shape.
Composition and introduction of elbow pushing machine
Elbow push machine: including chassis, chassis is arranged in the middle of the bracket, which is characterized in that: the bracket is provided with an elbow mold;The back of the elbow mould is provided with a hydraulic device, the middle is provided with a push frame, the front end is provided with an electric heating device, the push frame is installed on the elbow mould;The push frame is provided with a control box, the control box is electrically connected with a hydraulic device and an electric heating device.Further, the hydraulic device comprises a hydraulic pump and a hydraulic cylinder.The electric heating device comprises an intermediate frequency heater and an electric heater;The electric heater is a heating coil.The utility model comprises an elbow mold, a hydraulic cylinder and a push frame are arranged on the guide rod of the elbow mold, and a heating coil and a mold part are arranged in the front part of the guide rod.The utility model saves a great deal of manpower and time, and the utility model can process the elbow of large diameter by using the blank of small diameter, and the type of elbow is increased.An elbow machine relates to a device for pushing and making an elbow.It is mainly designed to solve the problem of large wall thickness difference of pressing elbow.It includes frame, intermediate frequency heater, hydraulic system, with fixed bed fixed to the frame of the back-end, fixed with a hole at the center of the machine, the oil cylinder is fixed on the fixed table, no bar and rod of oil cylinder cavity respectively through the pipe connected to the hydraulic system, have a haircut and the oil cylinder cylinder rod fixed contact, have a haircut central hole, intermediate frequency heater with heating coil wire connection, wedge key hole is at the back of the core rod from heating circle and have a haircut in the center of the hole and the center of the fixed station through the hole, wedge key wear in the key hole wedge core rod, activity semicircle card board is composed of upper and lower two semicircle card board,The upper and lower two semicircular card boards are mounted on the front surface of the push head and are covered with the core rod and the core rod has a gap.The advantage is that the produced elbow wall thickness is uniform.
