Description

Technical Field

[0001] This utility model relates to the technical field of cutting, and in particular to a rail steel cutting device. Background Technology

[0002] During the processing of rails, a cutting device is needed to cut the rails to a suitable length. In the prior art, a utility model patent with patent application number 201120157475.3 discloses a cutting machine, which mainly consists of a handheld cutting machine and a base. When cutting a workpiece, the workpiece is placed on the base, and then the operator presses the handheld cutting machine to lower it, so that the cutting machine can cut the workpiece. However, there are the following problems in the use of this device: when cutting a workpiece, the labor intensity of manually pressing the cutting machine is relatively high, and it is inconvenient to use. Therefore, there is a need for a device that can automatically cut the workpiece. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a rail steel cutting device that can automatically move the cutting machine during the cutting process, eliminating the need for manual movement of the cutting machine, making it convenient to use, with low labor intensity and high practicality.

[0004] This utility model discloses a rail steel cutting device, comprising a base plate, a support frame, a fixed plate, and a cutting machine. The fixed plate is mounted on the upper end of the base plate via the support frame, and the cutting machine is equipped with a cutting blade. It also includes a moving mechanism and a clamping mechanism. The cutting machine is mounted on the base plate via the moving mechanism, which is used to move the cutting machine back and forth. The fixed plate has a vertically connected slot, and the cutting blade is located within the slot. The clamping mechanism is mounted on the fixed plate and has a clamping and fixing function. When cutting the rail steel, the rail steel is first placed on the base plate, ensuring the part to be cut is above the slot in the fixed plate. Then, the rail steel is clamped and fixed by the clamping mechanism. The cutting machine is then turned on, causing the cutting blade to rotate. The moving mechanism then moves the cutting machine and the cutting blade in the back-and-forth direction. During this movement, the cutting blade contacts the rail steel and cuts it. The device automatically moves the cutting machine during the rail steel cutting process, eliminating the need for manual movement. It is convenient to use, has low labor intensity, and is highly practical.

[0005] Preferably, the clamping mechanism includes a torque motor, a lead screw, and two sets of clamping plates. The torque motor is fixedly mounted on the front end of the fixed plate, and the lead screw is rotatably mounted on the fixed plate. The front and rear parts of the lead screw are respectively provided with external threads in opposite directions. The front end of the lead screw is connected to the output end of the torque motor. The two sets of clamping plates are respectively screwed to the front and rear parts of the lead screw. Both sets of lead screws are slidably mounted on the fixed plate. When cutting the rail steel, the torque motor is first turned on, and the torque motor drives the lead screw to rotate. The rotating lead screw causes the two sets of clamping plates to move closer to each other in the front-rear direction until the two sets of clamping plates contact the front and rear ends of the rail steel respectively. The rail steel is then clamped and fixed by the two sets of clamping plates, which facilitates the clamping and fixing of the rail steel.

[0006] Preferably, the moving mechanism includes an electric slide rail and a sliding plate. The electric slide rail is mounted on the base plate, and the sliding plate is mounted on the electric slide rail. The electric slide rail is used to move the sliding plate back and forth. The cutting machine is mounted on the electric slide rail. When cutting the rail steel with the cutting blade, the electric slide rail is opened, and the electric slide rail drives the sliding plate to move in the back and forth direction. The sliding plate moves the cutting blade in the back and forth direction through the cutting machine. This facilitates the back and forth movement of the cutting blade.

[0007] Preferably, the device also includes a fixed frame, a cylinder, a push rod, and a pressure plate. The fixed frame is fixedly installed on the upper end of the fixed plate, the cylinder is fixedly installed on the upper end of the fixed frame, the push rod is slidably installed on the upper part of the fixed frame, the upper end of the push rod is connected to the output end of the cylinder, and the pressure plate is fixedly installed on the lower end of the push rod. When cutting the rail steel at the upper end of the fixed plate, the cylinder is opened, and the cylinder causes the pressure plate to descend through the push rod until the pressure plate presses the rail steel tightly and fixes it on the upper end of the fixed plate. This improves the stability of the rail steel during cutting and ensures the cutting accuracy.

[0008] Preferably, the assembly also includes a vertical plate, a hydraulic cylinder, a sliding rod, and a positioning plate. The vertical plate is fixedly installed on the upper end of the base plate, the hydraulic cylinder is fixedly installed on the right end of the vertical plate, the sliding rod is slidably installed on the vertical plate, the right end of the sliding rod is connected to the output end of the hydraulic cylinder, and the positioning plate is fixedly installed on the left end of the sliding rod. Before cutting the rail steel, the distance between the positioning plate and the cutting blade in the left-right direction is first measured, and the hydraulic cylinder can be engaged to move the sliding rod to move the positioning plate until the distance between the left end of the positioning plate and the cutting blade in the left-right direction is the required length of the rail steel. Then, the rail steel is placed on the upper end of the fixed plate, so that the right end of the rail steel is close to the left end of the positioning plate, thus completing the positioning of the rail steel; this facilitates the positioning and cutting of the rail steel.

[0009] Preferably, a rubber pad is provided at the lower end of the pressure plate; this arrangement prevents the pressure plate from damaging the rail steel.

[0010] Preferably, the torque motor is equipped with a leakage current protector; this feature improves the safety of the torque motor during use.

[0011] Compared with the prior art, the advantages of this utility model are: the cutting machine can be moved automatically during the cutting of rail steel, eliminating the need for manual movement of the cutting machine, making it convenient to use, reducing labor intensity, and increasing its practicality.
