Description
Technical Field
[0001] The invention belongs to the technical field of pipe cutting, in particular to a new type of pipe cutting machine. Background Art
[0002] With the rapid development of the domestic economy, the application of pipes has become more and more common, especially in the fields of construction, machinery and other industries. Traditional pipes are generally cut manually or mechanically, and manual cutting is gradually replaced by pipe cutting machines due to poor cutting accuracy, high labor intensity and low efficiency.
[0003] At present, the existing pipe cutting machines generally include a loading mechanism, a cutting mechanism and a unloading mechanism. The loading mechanism transports the pipe to be cut to the cutting mechanism. After the cutting mechanism cuts the pipe into sections, the cut pipe sections are transported to the unloading mechanism. The traditional unloading mechanism generally includes a manipulator and a pipe placement rack. The manipulator clamps the cut pipe and moves the pipe to the pipe placement rack. This unloading method is inefficient, which in turn affects the cutting efficiency of the pipe. Summary of the invention
[0004] The purpose of the present invention is to solve the above problems in the prior art and propose a new type of pipe cutting machine. The technical problem to be solved by the present invention is: how to solve the problem of low efficiency of pipe cutting.
[0005] The purpose of the present invention can be achieved by the following technical solutions:
[0006] A new type of pipe cutting machine comprises a loading mechanism, a cutting mechanism and a unloading mechanism which are arranged in sequence along the transverse direction, and is characterized in that the unloading mechanism comprises a mechanical clamp which can move laterally and can clamp the pipe and a turning assembly located below the mechanical clamp, and a material receiving rack is arranged on the left and right sides of the turning assembly, and the turning assembly comprises a unloading rack, and a left unloading plate and a right unloading plate which can be used to place the pipe are hinged on the unloading rack, and a left unloading cylinder and a right unloading cylinder are also arranged on the unloading rack, and the left unloading cylinder is connected to one side of the left unloading plate and can push the left unloading plate to swing up and down, and the right unloading cylinder is connected to one side of the right unloading plate and can push the right unloading plate to swing up and down.
[0007] The feeding mechanism transports the pipe to be cut to the cutting mechanism. In order to ensure the stability of pipe cutting, the mechanical clamp clamps one end of the pipe. After the cutting mechanism cuts the pipe into sections, the left unloading cylinder and the right unloading cylinder respectively drive the corresponding left unloading plate and the right unloading plate to move, so that the left unloading plate and the right unloading plate are in a V shape. The mechanical clamp releases the cut pipe, and the pipe falls into the V-shaped groove formed by the combination of the left unloading plate and the right unloading plate. The left unloading cylinder drives the left unloading plate to swing downward so that the left unloading plate tilts downward, and the pipe slides along the left unloading plate and slides to the left receiving rack. When the left receiving rack is full of pipes, the right unloading cylinder drives the right unloading plate to swing downward so that the right unloading plate tilts downward, and the pipe slides along the right unloading plate and slides to the right receiving rack. This structure significantly improves the unloading efficiency of pipes, and this structure can realize two-way unloading, further improves the convenience of unloading, and improves the pipe storage capacity of the unloading mechanism.
[0008] In the above-mentioned new type of pipe cutting machine, the material receiving rack includes a rack body and a plurality of support rods on the top of the rack body, all the support rods are arranged in a horizontal interval, and all the support rods are arranged in a longitudinal direction, and the support rods are arranged in an inclined manner, and the end of the support rod facing the material turning component is high, and the end away from the material turning component is low. Through the arrangement of this structure, the plurality of support rods play a supporting role for the pipes, and the pipes can slide along the inclined direction of the support rods, which facilitates the accumulation of the pipes on the material receiving rack.
[0009] In the above-mentioned new pipe cutting machine, a vertically arranged limit rod is fixed on the frame, and there are a plurality of limit rods, all of which are arranged in the transverse direction, and the limit rod is close to the end of the support rod away from the material turning assembly. Through the arrangement of this structure, the limit rod plays a role of blocking and limiting the pipe, preventing the pipe from sliding from the receiving rack to the ground.
[0010] In the above-mentioned new type of pipe cutting machine, the feeding mechanism includes a bracket, a slide plate arranged on the bracket along the transverse sliding, a feeding assembly arranged on the slide plate and capable of driving the pipe fitting to move, and a driving member capable of driving the slide plate to move back and forth laterally. The feeding assembly includes a fixed seat fixed on the slide plate, a support cylinder arranged on the fixed seat, a slider cylinder arranged at the front end of the support cylinder, and an inner support clamp arranged on the side wall of the slider cylinder. The inner support clamp has two inner support clamps and is arranged relatively up and down the slider cylinder. The two inner support clamps can move radially along the slider cylinder. An oil cylinder is fixed on the fixed seat. The oil cylinder and the inner support clamp are connected by a connecting rod assembly. The oil cylinder drives the two inner support clamps to move closer to or away from each other through the connecting rod assembly. Through the arrangement of this structure, during the operation of the pushing mechanism, the pipe fitting is hollow, and the driving member drives the drag plate to move forward, so that the slider tube moves into the pipe fitting, and the oil cylinder drives the two inner support clamps to move radially along the slider tube through the connecting rod assembly, so that the two inner support clamps are stretched outward, and the two inner support clamps are abutted against the inner circumferential surface of the pipe fitting, and the driving member drives the drag plate to continue to move forward, and the feeding assembly drives the pipe fitting to move forward, thereby realizing automatic loading of the pipe fitting. The loading method of this structure will not cause damage to the outer circumferential surface of the pipe fitting, and the pipe fitting will not be deformed when subjected to large force, thereby avoiding damage to the pipe fitting during the loading process.
[0011] In the above-mentioned novel pipe cutting machine, a guide rail is arranged on the bracket in the horizontal direction, a slider is slidably arranged on the guide rail, the carriage is fixed on the slider, the driving member includes a rack arranged on the frame in the horizontal direction and a motor fixed on the carriage, and the motor shaft is provided with a gear meshing with the rack. Through the arrangement of this structure, after the motor shaft rotates, the carriage is driven to move in the horizontal direction through the gear rack.
[0012] In the above-mentioned new type of pipe cutting machine, the cutting mechanism includes a casing, a pipe clamp and a cutting knife assembly arranged on the discharge end of the casing, the pipe clamp is arranged in the discharge end of the casing, and the pipe clamp includes a plurality of clamping blocks arranged along the circumference of the casing, all of which can move radially along the casing at the same time, and the side walls of the clamping blocks have an arc-shaped surface that can fit with the outer circumferential surface of the pipe. In the present structure, several clamping blocks move radially inwardly along the casing to clamp and position the pipe. The arrangement of the arc-shaped surface allows the side wall of the clamping block to fit with the outer peripheral surface of the pipe, ensuring that there is a large contact area between the clamping block and the pipe, thereby improving the positioning effect on the pipe. Moreover, the pipe clamp and the cutter assembly in the present structure are arranged at the same end of the casing, which shortens the distance between the pipe clamp and the cutter assembly compared with the prior art. The end of the pipe close to the cutter assembly has a very good positioning effect, avoiding the situation where the end of the pipe close to the cutter assembly is suspended, so that during the process of cutting the pipe, the end of the pipe close to the cutter assembly is not prone to shaking up and down, thereby reducing the noise during the pipe cutting process, ensuring that the cut surface of the pipe has good flatness, and improving the stability of pipe cutting.
[0013] Compared with the prior art, the novel pipe cutting machine of the present invention has the following advantages: the structure significantly improves the feeding efficiency of pipes, and the structure can realize two-way feeding, further improving the convenience of feeding, and improving the pipe storage capacity of the feeding mechanism.
