Description

Technical Field

[0001] The invention relates to automatic production equipment for insulating steel bars, in particular to a single automatic production line for insulating steel bars for high-speed railways, and belongs to the technical field of automation equipment. Background Art

[0002] At present, the raw material for producing 5598mm insulated steel bars for high-speed railways (this type of insulated steel bars involved in this application are also called insulated steel bars when used in high-speed railways, but the steel bars are not covered with insulating tubes) is CRB600H high-ductility cold-rolled ribbed steel bars with a diameter of 8mm and a length of 11216mm; the production method is: a bundle of raw materials weighing about 2 tons is placed on a stand, the bundle of raw materials is unpacked, and then each steel bar is manually placed on an ordinary punch press for fixed-length punching, and each steel bar is punched twice, and each is punched to a length of 5598mm; the steel bars entering and exiting the punch press are assisted by guide wheel motors to reduce the labor intensity of the operator, and the punched steel bars fall into the collection trough. After a bundle of raw materials is punched and cut, the punched steel bars are hoisted to the bending hoop. The bending hoop equipment consists of two ordinary bending machines. The distance between the bending machines is adjusted to ensure the size of the bending hoop. Two operators lift five steel bars at a time and place them at the bending machine for bending. After the bending, the two operators put the steel bars into the collection tank. After the number of steel bars bent meets customer needs, the steel bars are packaged and transported away. The current production method has high labor intensity for operators and low automation of equipment. It is basically completely manual operation with low efficiency. It requires cooperation of multiple people to complete. Since the steel bars are long and have a certain weight, safety accidents may occur when the staff is not focused, causing personal injury. Since the batch size required for this type of steel bars is generally large, it is necessary to develop production lines to improve the automation of 5598 insulated steel bars for high-speed rail to reduce the labor intensity of operators, reduce labor costs, improve efficiency, and ensure the safety of the production process.

[0042] The bending device includes two hoop bending machines fixedly installed near the front and rear ends below the guide groove. In the figure, 601 is the first hoop bending machine and 602 is the second hoop bending machine. The hoop bending machine includes a hoop bending motor 6011.

In the figure, the first hoop bending frame has a stop surface 6016. Fig.11 It is a schematic diagram of the second hoop bending machine. The difference between the two places is the stop surface.

[0046] The cylinder in the present application can be replaced by any one of an electric push rod, an oil cylinder, and an electromagnet. The pressing device can also directly use a lifting mechanism to drive the pressing plate to rise and fall.

[0047] During production on this production line, bundles of steel bars are placed on the carrier frame. After unpacking, the vibration motor is started to vibrate the bundles of steel bars to separate the crossed steel bars so that the steel bars are no longer entangled. Then the steel bars to be cut are manually placed on the active clamping wheel. The active clamping wheel and the passive clamping wheel clamp the steel bars and transport them backward. The steel bars are supported on the support plate after passing through the feeding guide tube and the pulley. When the steel bars reach the first steel bar detection switch, the clamping motor and the material guide motor slow down. When the first steel bar detection switch B senses, the second pressing device is in the pressing state to block the steel bars. The clamping motor and the material guide motor The machine stops moving and adjusts the position of the first steel bar detection switch to ensure that the length of the steel bar after cutting is qualified. At this time, the first pressing device presses down to press the steel bar, and the shearing motor is activated to cut the steel bar. After the position detection switch 319 is sensed, the shearing motor stops moving, and the first pressing device and the second pressing device are both lifted up. At this time, the guide motor is activated to drive the cut steel bar to run. When the second steel bar detection switch A is sensed, the guide motor slows down. When the second steel bar detection switch B is sensed, the guide motor stops moving, and the opening and closing cylinder drives the support plate to move, and the bottom of the guide groove is opened for material dropping. After the steel bars pass between the supporting plate and the pressing plate of the blanking device, the material switch senses it, and the opening and closing cylinder drives the supporting plate to reset, and the alignment cylinder drives the steel bars to be positioned. After the alignment cylinder returns to its position, the mandrel cylinders of the two hoop bending machines drive the mandrels to be pushed out, and at the same time the pressing cylinder presses down to hold the steel bars. After all the cylinders are in place, the two hoop bending motors operate at the same time, and after the bending block rotates to the set angle (the specific degree of rotation can be adjusted according to the strength of the steel bars to ensure the product is qualified), it returns to its original position. After the origin detection switch senses it, all the pressing cylinders and mandrel cylinders return. After returning to their position, all the unloading cylinders operate to push the bent steel bars into the collection trough 800, and the first cutting of a steel bar is completed.

[0048] After a 11216mm long steel bar is cut twice, a 20mm long steel bar head will remain in the feeding tube of the clamping device. When another steel bar is clamped and fed later, the 20mm long steel bar head will be knocked out of the feeding tube and fall out of the equipment without affecting production. When the number of 5598 insulated steel bars for high-speed rail is sufficient, the operator will pack the produced 5598 insulated steel bars for high-speed rail, remove the packed 5598 insulated steel bars for high-speed rail and continue production.
