Description

Technical Field

[0001] The invention relates to production equipment for insulating steel bars for high-speed railways, in particular to a full-automatic production line for multiple insulating steel bars for high-speed railways at a time, belonging to the technical field of steel bar production automation equipment. Background Art

[0002] The 5598 insulated steel bars used in high-speed railways are used in large quantities. They are made of 5598mm long steel bars bent at the designed positions near the two ends. The raw materials for producing this 5598 insulated steel bar are φ8mm 11216mm long CRB600H high-ductility cold-rolled ribbed steel bars. The production method is: put a bundle of raw materials weighing about 2 tons on the stand, unpack the bundle of raw materials, and then manually place each steel bar on an ordinary punch press for fixed-length punching. Each steel bar is punched twice, and each is punched to 5598mm long. 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 hoops. The bending hoop equipment is composed of two ordinary bending machines. The distance between the bending machines is adjusted to ensure the size of the bending hoops. Two operators lift five steel bars at a time and place them on the bending machines for bending. After the bending, the two operators put the steel bars into the collection trough. When the number of bent steel bars meets customer needs, the bent steel bars are packaged and transported away. The current production method has high labor intensity for operators and safety risks. The equipment has a low degree of automation and is basically entirely operated manually, which is inefficient and has high labor costs. Summary of the invention

The first incoming steel bar is blocked by the bottom of the U-shaped frame, and the subsequent steel bars are blocked by the previous steel bar in turn. In an even more optimized manner, the U-shaped edge end portion of the upper part of the U-shaped frame is bent upward, so that the steel bars can move into the U-shaped frame more conveniently.

A group of steel bar detection switches are installed in the combined guide grooves before and after the material blocking cylinder. Each group of steel bar detection switches includes one or more steel bar detection switches. In this embodiment, each group of detection switches consists of two steel bar detection switches. The two steel bar detection switches installed in the combined guide groove in front of the material blocking cylinder are used to slow down and stop when arriving at the cutting station, respectively. The two steel bar detection switches are respectively for deceleration and stopping when arriving at the hoop bending station. In one group, the front steel bar detection switch is for deceleration. After the controller receives the switch signal, it controls the motors related to the conveying to decelerate. The rear steel bar detection switch is the stop switch. After the controller receives the stop switch signal, it controls the motors related to the conveying to stop. The steel bar detection switch is not shown in the figure.

A second hoop bending machine 513 is installed near the steel bar cutting machine, and a clamping device is installed in conjunction with each hoop bending machine; the clamping device is a clamping cylinder 510 in the up and down directions, and a pressing plate 511 is fixed on the cylinder rod of the clamping cylinder.

The mandrel is fixedly connected to the mandrel oil cylinder 5087 in the left and right directions, and the bending block of the first hoop bending machine has a stopper 5089. The second hoop bending machine has the same structure as the first hoop bending machine, except that there is no stopper on the bending block of the second hoop bending machine.

[0050] There are multiple notches on the side B513 of the combined guide groove, and a steel pushing device is installed in each notch. The steel pushing device includes a steel pushing box 600, and a steel pushing cylinder 601 is installed on the steel pushing box. The cylinders and oil cylinders of the above-mentioned second chain bed steel bar cutting machine and hoop bending machine are all connected to the controller for control.

[0051] The working process of this production line is as follows: all lifting and vibrating tables are lifted, and bundles of steel bar raw materials are placed on them. After unpacking, vibration begins. The baffle on the vibration plate on the lifting and vibrating table can prevent the steel bars from falling. After the steel bars are vibrated, the lifting and vibrating tables are lowered at the same time, and the steel bars fall onto the first chain bed. The first chain bed is started to transport the steel bars to the step-by-step conveyor paving device. After the steel bars are transported to the step-by-step conveyor paving device, the step-by-step conveyor paving device is started, and the first chain bed is paused at the same time. The cam drives the mobile frame to rotate one steel bar at a time, and it is transferred from the mobile frame to the lowest step of the fixed step plate. At the same time, if there are steel bars on the upper step of the fixed step plate, they are also moved up step by step under the action of the mobile step plate. The uppermost steel bar is moved to the paving plate to complete the paving. This device can control the chain bed to transport steel bars to the step-by-step conveyor paving device at intervals of a certain period of time through the program. The step-by-step conveying and paving device starts to convey the steel bars to the paving plate one by one, and slides from the paving plate to the second chain bed. The counter on the paving plate counts the steel bars that have passed. The steel bars move in the direction of the U-shaped frame on the second chain bed and are blocked when they reach the bottom of the U. The subsequently conveyed steel bars are blocked by the previous steel bars in turn. The active clamping wheel is located under the stopped steel bars. When the number of steel bars reaches the designed number (such as 6), the step-by-step conveying and paving device and the second chain bed stop, and the passive wheel cylinder moves downward to clamp the steel bars between the active wheel and the passive wheel. At the same time, the transmission shaft drives the cylinder to lift the passive roller. At this time, the steel bars are supported on the passive roller. The clamping motor is started, and the steel bars pass through the pre-shear guide groove and the shearing device into the combined guide groove. The guide roller motor is also started to drive the guide roller to The roller conveyor reaches the steel bars in the combined material trough. At this time, the material blocking plate in the combined material trough is in the material blocking state. After the first set of steel bar detection switches detect that it is in place, each conveying motor stops. At this time, the hydraulic shearing machine actuates the steel bar to cut the steel bar, the hydraulic shearing machine resets, the material blocking cylinder is lifted, and each guide roller motor starts to send the steel bar to the bending hoop station. Under the action of the second set of steel bar detection switches, the tail end of the steel bar reaches the first bending hoop machine. The stopper can prevent the steel bar from moving backward due to inertia. The clamping device acts to clamp the steel bar, the mandrel hydraulic cylinder drives the mandrel to extend, and the bending block hydraulic cylinder drives the bending block to rotate to complete the bending. After the bending block returns to its place, the clamping cylinder is lifted at the same time. At this time, the guide groove cylinder acts to open side A, and the steel pusher cylinder of the steel pusher is pushed out to push the steel bar with the bent hoop into the collection frame. The steel pusher cylinders of each steel pusher return, and side A is reset when the guide groove cylinder is reset. Then the clamping motor transports the steel bars into the combined guide groove for cutting and bending. The steps are the same as above. After there is no steel bar above the second chain bed, the rollers drop and the step-by-step conveying and spreading device starts to spread the material.
