The rolling sleeve cleaning burr machine manufactured by the project.
1 system working principle To ensure the cleanliness of the rolling sleeve, each workpiece needs to be brushed twice.
At each processing station, the opposite nylon bristles are used to clean the burrs on both ends. How it works 1.
Blow out the discharge and describe the discharge as follows. Up to 20 workpieces can be placed on the rack, but only one can be released at a time for processing. To this end, while the stop bar releases a workpiece, the separation bar blocks the workpiece behind it; when the workpiece falls to the waiting position, the stop bar is lowered and the separation bar is raised to prepare for the next discharge.
Feeding. The brackets that can be moved up and down, and moved back and forth are responsible for the handling of the workpiece. There are three openings on the bracket to hold the workpiece to ensure that the workpiece does not fall during the feeding process.
Press tight. After the carriage advances to the machining position, it is lowered. The rolling sleeve is supported by four rollers that can be rotated. At this time, the pressure roller directly above the workpiece is lowered, and the workpiece is pressed to prevent falling off during processing. The pressure roller is a metal disc with a high degree of smoothness and moderate hardness around its central axis.
Clean the burrs. This process is the core of the machine's work. After the workpiece is pressed, the four rollers are rotated by the motor and the workpiece is placed. Rotation under the action of friction. At this point, the rotating nylon brush is opposite to the dragon brush. The burrs remaining on the end face of the rolled food are removed by a large force. After the processing, the brush retreats and stops, the workpiece rotation stops, and the pressure roller rises. When the brush is processed, coolant is sprayed between the brush and the workpiece. Flush the burrs. And it works as a cooling.
Blowing. One piece of water that has been brushed twice and the residual coolant must be removed. To this end, an air nozzle is designed to discharge at high speed. The workpiece that has reached the processing requirements is pushed out from the discharge port by the bracket and rolled onto the discharge rack. A counter is installed at the exit to determine the workload of each class of workers.
2 The system consists of the entire part of the system consisting of the signal part of the electrical part of the pneumatic part, the control part of the river and so on. , 1 pneumatic part. The pneumatic part consists of six cylinders, all of which are Japanese company products. , the heart of the support circuit 2, its function is divided into workpieces. Stop the stick. Pressure roller, and 8 lifts. The bracket lifts. The carriage moves back and forth. Among them. The lifting and moving cylinders make the cylinders. 1 is to overcome the compressibility of the gas, so that the movement speed is stable, to ensure that the workpiece does not fall during the transportation process. The machine is transformed into the pressure of the oil to promote the smooth movement of the cylinder piston. Each cylinder in 2 is in an initial state.
2 electrical part. This machine includes 13 motors. The electrical circuit is a motor that separates the coolant from the iron chips. 12圮 The motor of the mist collector that collects the coolant oil mist, the elbow 3 is the electric pump of the coolant pump, and the sneak peek of the 20-inch pan cover. The mail milk 6 is the motor that moves the brush forward and backward. 4 phase motor milk 1 54 drives the brush to rotate. Two single-phase motor cliffs 61 elbow 62 drive roller rotation. Except for the criminals, the other motors are all 17 public products in Japan.
It is the position stop, that is to say, the actuators such as the motor and the cylinder are stopped in the position and waiting for manual processing, thus avoiding hard collision and damaging the machine.
4 Conclusion The rolling sleeve cleaning burr machine has high processing precision, reliable work and high efficiency. In Japan, many automated production lines have equipment for cleaning burrs. At present, China's production enterprises have undoubtedly provided a good solution to this work for parts such as hydraulic and pneumatic valves.

Programmable controller configuration programming network China Labor Press, 2 Zhu Chunbo and so on. 1 controlled pneumatic simulation production line machine and hydraulic, 1999 front end loader electrical part also includes timer output. The brush processing time timer sets the machining time according to the machining accuracy, the brush exchange counter calculates the total number of labors from the start of each brush, and replaces the new brush with the set value, and the daily production counter is used to measure the work of each shift. The amount of work.
Since the loader adopts a single-arm structure, the operator's vision history during work is wide, which not only ensures the safety of the operation, but also improves the work efficiency. According to the introduction, the single-arm 5-carrier The price is 30 lower than most current dual-arm loaders, and the maintenance cost is correspondingly lower.
Hu Zhenglong scientists studied the use of laser bending metal Polish Institute of Basic Technology Institute of Research Institute to allow the laser to bend the metal, which will be followed by laser drilling and cutting. New progress after printing local heat treatment According to reports, the main point of this technology is to move the laser beam along the bending line on the material surface, and then use the water or gas to cool the heated part of the material, which will generate an internal stress field. The result is a bend along the laser moving line. The bending is generated by the computer under the control of the curved line along the metal. It does not require external force or forming, and the force forming tool and the rolling forming tool. According to the Institute of Basic Technology, the sudden change in the local temperature of the material lasts for a very short time, so the microstructure of the material changes only slightly.
Sometimes, the process has been found to improve the organization and properties of the material.
Even brittle materials like cast iron can be formed in this way.
This result is difficult to achieve with traditional art.
