As shown in fig. 1 to 4, a synchronous cutting method for discharging a pipe includes the following steps:
s1, conveying the pipe into the cutting machine and extending into the cutting device 1, wherein the extending speed of the pipe is V1;
s2, the length of the pipe to be cut is L1, when the length of the pipe extending into the cutting device reaches L2, wherein L2 is less than L1, the control system controls the cutting device 1 to start moving and accelerate, when the cutting device 1 moves for a distance D, the speed V2 of the cutting device 1 is equal to the speed V1 of the pipe extending into the cutting device, wherein L2 is L1-D, D is the moving distance that the control system controls the cutting device (1) to start moving and accelerate to a speed V1, and D is automatically calculated by the control system;
s3, when V2 is V1, the cutting device 1 and the pipe are controlled to move at the same speed, and the control system simultaneously controls the cutting head 11 on the cutting device 1 to rotate to cut the pipe with a length of L1.
The cutting device 1 is used for cutting the pipe, and the specific cutting mode is laser cutting; the cutting machine is arranged at the output end of the pipe extrusion molding device, after the pipe is extruded and molded and is output outwards, the pipe directly extends into the cutting device 1, and then the pipe is cut by the cutting method. Cutting device 1 includes chuck 12 and cutting head 11, and chuck 12 is opened has the through-hole that supplies tubular product to pass, and cutting head 11 is installed on chuck 12, and is located one side of through-hole, and tubular product stretches into to the through-hole in, and cutting head 11 cuts tubular product. The whole cutting process is as follows: the pipe is output from the output end of the pipe extrusion molding device at a constant speed and directly stretches into the cutting, and the stretching speed of the pipe is V1; when the length L2 of the tube extending into the cutting head 11 is L1-D (L2 is smaller than the length L1 of the tube to be cut off, namely the length of the tube product cut off from the raw material tube is L1) with the position of the cutting head 11 as a zero point, the control system controls the cutting device 1 to start moving and accelerate, and the moving direction of the cutting device 1 is the same as the extending direction of the tube; when the cutting device 1 is moved a distance D (D ═ L1-L2), the speed of the cutting device 1 reaches V2(V2 ═ V1), i.e. the speed of the cutting device 1 goes from zero to V2, the distance moved is D, so that when V2 ═ V1, the position of the cutting head 11 is level with the pipe cutting point; when V2 is V1, the tube and the cutting device 1 are moved at the same speed, the speed is kept constant, and the control system controls the cutting head 11 to rotate to cut the tube to the desired length of L1.
This technical scheme, tubular product extrusion moulding is at ejection of compact in-process, and cutting device 1 follows tubular product and removes in order to cut tubular product, and tubular product need not to stop can realize being cut, consequently can set up the cutting machine at tubular product extrusion moulding device's discharge end, directly cuts the tubular product of discharging at the time, realizes that the ejection of compact and cutting go on in step, has avoided the consumption of tubular product unloading, transportation, material loading in-process to manpower and materials, has improved production efficiency. On the other hand, the pipe is directly cut into the required length after being extruded and molded, so that the generation of excess materials in the cutting process is reduced, and the loss of the pipe is reduced; the pipe does not need to be clamped in the cutting process, so that errors caused by the clamping process are avoided, and the machining precision is improved.
Further, step S3 is followed by step S4: after the first section of the pipe is cut, the cutting device 1 is reset, and when the extending length of the pipe reaches L2, the steps S2 to S3 are repeated.
After the steps S1 to S3 are performed, the cutting device 1 cuts out a first section of the tube; after the cutting is completed, the cutting apparatus 1 is reset, i.e., retracted to the initial position before the movement of step S2. In the resetting process of the cutting device 1, the pipe continuously extends into the device; generally, the length L1 of the cut tube is longer, and the length L2 of the tube extending into the tube is closer to L1, so that the time required for the tube extending into the length L2 is longer than the time required for the cutting device 1 to reset. After the cutting device 1 is reset, when the extending length of the pipe reaches L2 again, the control system controls the cutting device 1 to start moving and accelerating, and steps S2 and S3 are executed to cut a second section of pipe; and repeating the steps S2 to S4 to continuously cut the pipe. Step S4 is to complete the whole cutting process to continuously cut the pipe material continuously discharged, thereby ensuring the processing efficiency.
The numerical values of D and L2 are calculated by a control system, namely, the extending speed V1 of the pipe is firstly obtained (the speed can be obtained by the extruding speed of the pipe in the pipe extruding and forming device and can also be measured by arranging a speed measuring device), the control device controls the cutting device 1 to move, therefore, the acceleration of the cutting device 1 can be known, the distance D required for the movement of the cutting device 1 from zero to V1 is calculated, and then the length L1 of the pipe required to be cut is subtracted by the D to obtain L2. Therefore, when the pipe extends into the pipe to reach L2, the cutting device 1 is controlled to move; when the speed of the cutting device 1 reaches V2(V2 ═ V1), the cutting head 11 is flush with the cutting point on the pipe, i.e. the distance between the cutting head 11 and the end face of the pipe is L1; the length of the cut tubing was therefore L1.
When the specific value of V1 is determined, the specific value of D can be determined, and on the basis, if the specific value of L1 is different, the specific value of L2 is also different; that is, if the pipes with different lengths need to be cut under the same V1, the L2 is automatically calculated according to the specific numerical systems of L1 and D so as to meet the requirements of cutting the pipes with different lengths. When V1 is different, the system will re-determine D, so L2 will change with V1 and D, with the value of L1 unchanged.
Through step S2, not only can the synchronous cutting be realized when the tubular product is discharged, but also L2 and D can be accurately calculated for different tubular product stretching speeds V1 and the length L1 of the tubular product required to be cut off, so that the control system can accurately control the movement of the cutting device 1, and the length precision of the cut tubular product is ensured.
Further, the cutting head 11 rotates in opposite directions when cutting the tube two adjacent times. For example, when the cutting head 11 cuts out the first section of pipe, the rotation direction is clockwise; when the second section of pipe is cut out, the rotating direction is anticlockwise; when a third section of pipe is cut, the rotating direction is clockwise, and so on. In the actual operation of the cutting device 1 and the cutting head 11, more electric wires need to be connected, and if the cutting head 11 always keeps rotating in the same direction, the electric wires are easy to wind; therefore, the rotating direction of the cutting head 11 is set to be opposite when the pipe is cut twice, and the electric wire can be prevented from being wound to influence normal work.
Further, after the cutting head 11 cuts off the pipe, the control system controls the baffle 21 in the blanking device 2 to open, so that the pipe falling in the blanking device 2 continues to be blanked, and then the baffle 21 is retracted to receive the next section of pipe.
The blanking device 2 is used for blanking the cut pipe and is arranged at one end of the cutting device 1, which is far away from the pipe feeding; the pipe falls into the blanking device 2 after being cut off, the baffle 21 of the blanking device 2 is opened first, so that the pipe is blanked continuously, and the pipe can be blanked into a material storage device specifically or can be blanked into the next processing procedure; and after blanking, the baffle plate 21 is retracted. After the cutting head 11 finishes cutting, the pipe falls into the blanking device 2, and in the process, the consumed time is short, so that the control system can wait for one second after the cutting head 11 finishes cutting, and then controls the baffle 21 of the blanking device 2 to open; after the baffle 21 is opened, the pipe is immediately fed to a storage device or the next machining process, the time spent here is short, so that the baffle 21 can be opened for one second, and then the baffle 21 is retracted to receive the next section of pipe. After the pipes are cut off, the pipes are blanked by controlling the blanking device 2 to be in one section, so that the pipes can be prevented from being directly blanked into the storage device, and the messy arrangement is avoided; one section unloading of tubular product can directly be expected during to next manufacturing procedure in, has improved machining efficiency, has reduced the manpower and materials cost of tubular product transportation.
Further, the distance between the blanking device 2 and the initial position of the cutting device 1 is adjustable. The blanking device 2 needs to bear the pipe falling after being cut off, so that the blanking device 2 should stably bear the pipe as much as possible, and particularly, the center of the blanking device 2 is close to the center of the pipe as much as possible; therefore, the blanking device 2 should be arranged at different positions for pipes of different lengths. A certain distance (the distance is greater than or equal to D) is kept between the blanking device 2 and the initial position of the cutting device 1, so that the cutting device 1 can reciprocate in a certain range; as mentioned above, when V1 is different, D is different (specifically, the larger V1, the larger D is), so that the distance between the initial positions of the blanking device 2 and the cutting device 1 is adjustable, and the cutting device can adapt to V1 with different sizes, thereby ensuring that the cutting device 1 does not interfere with and affect the movement in the moving process.
Further, in step S3, the rotation speed of the cutting head 11 is greater than the pipe extending speed V1.
The pipe is cut, typically by rotating the cutting head 11 through 360 ° so that the cutting line forms a closed loop. During the rotation and cutting processes of the cutting head 11, the cutting device 1 and the pipe keep moving, so the cutting speed of the cutting head 11 directly affects the moving distance of the cutting device 1, i.e. the slower the rotation speed of the cutting head 11, the longer the distance to be moved by the cutting device 1, the lower the cutting efficiency, and the longer the length of the cutting machine. The rotating speed of the cutting head 11 is set to be greater than the pipe extending speed V1, so that the moving distance of the cutting device 1 can be reduced, the processing efficiency is improved, the total length of the cutting machine is reduced, and the occupied area of equipment is reduced.
Further, in step S2, the length of the tube inserted is detected by the encoder. The encoder can measure the linear displacement, and in step S2, the pipe extending length can be calculated according to the pipe extending speed and time, and the pipe extending length can also be measured by the encoder; the encoder is small in size, convenient to install, precise in detection and capable of improving machining precision.
Further, in the pipe extending process, the limiting mechanism 3 in the cutting device 1 limits the pipe in the radial direction, so that the pipe and the cutting device 1 can move coaxially. Stop gear 3 is used for radially spacing to tubular product, and stop gear 3 specifically encloses by a plurality of spacing subassemblies and establishes and form, and a plurality of spacing subassemblies enclose and establish the cavity that forms and to supply tubular product to pass, and the center of this cavity and the center collineation of through-hole on the chuck 12, tubular product pass cavity and through-hole in proper order and stretch into to cutting device 1 in. Tubular product is stretching into the in-process, and stop gear 3 bearing is lived tubular product and is had certain limiting displacement to tubular product on radial direction, avoids tubular product great at stretching into the in-process radial movement deviation, influences cutting accuracy.
Further, the limiting mechanism 3 can be tightened or expanded to adjust the distance between the limiting mechanism 3 and the center of the pipe. As mentioned above, the limiting mechanism 3 is formed by enclosing a plurality of limiting components, when the limiting components are close to the pipe, the limiting mechanism 3 contracts, the cavity becomes smaller, and the limiting mechanism is suitable for the pipe with smaller diameter or width; when the limiting assembly is far away from the pipe, the limiting mechanism 3 is opened, the cavity is enlarged, and the limiting mechanism is suitable for the pipe with larger diameter or width.
Further, in step S3, the motor 13 is started to rotate the driving gear 14 installed at the output end of the motor 13, the driving gear 14 rotates the driven gear 15 engaged with the driving gear 14, and the cutting head 11 installed on the driven gear 15 rotates with the driven gear 15. Specifically, a motor 13 is arranged on a chuck 12, a driving gear 14 is arranged at the output end of the motor 13, a cutting head 11 is arranged on a driven gear 15, the driving gear 14 is meshed with the driven gear 15, and the cutting head 11 can be driven to rotate when the motor 13 is started. The motor 13 and the driven gear 15 can be conveniently installed on the chuck 12, the transmission is stable, and the rotating direction of the cutting head 11 is convenient to adjust.
