The axial direction is provided with a screw, the screw is fixed with the output shaft of the main motor, and the outlet end of the heating cylinder is provided with a pipe forming mold. The traction machine includes a traction motor and a crawler driven by the traction motor, and also includes a PLC chip and a motor speed control. The device and the hopper quality change value collecting device, the motor governor and the hopper quality change value collecting device are all electrically connected with the PLC chip, and the motor governor and the traction motor are electrically connected.

However, the prior art is used to control the weight and thickness of the pipe; and the technical problem to be solved by the present invention is that the labor intensity of the worker is large and the processing efficiency is slow.

Summary of the invention

The technical problem to be solved by the present invention is to provide a plastic pipe forming device that solves the problems of high labor intensity, low processing efficiency, and low degree of intelligence during processing.

In order to solve the above technical problem, the plastic pipe forming device of the present invention comprises a work table, and a side of the work table is provided with a pole and a controller, and the working table is provided with a laterally movable left clamping seat and a fixed right clamping seat. One side of the pole is connected to the cylinder one, the cylinder one is connected with the left clamping seat, the left clamping seat and the right clamping seat are on the same straight line, the upper end of the vertical rod is connected with the cross rod, the lower end of the horizontal rod is connected with the cylinder 2, and the lower end of the cylinder is connected The forming head has a left half boss on the left clamping seat, and a right half boss on the right clamping seat, and a left half boss Forming a clamping gap with the right half boss, the inner wall of the left half boss is provided with a pressure sensor, and the outer side of the left half boss and the outer side of the right half boss are sleeved with the heater, and the jaw, the heater and the forming head are in the same strip On the center line, the heater, the cylinder one, the cylinder two, and the pressure sensor are respectively connected to the controller.

The controller is a PLC controller.

The workbench is provided with a sliding slot, and the left clamping seat is slidably connected to the workbench through the sliding slot.

The heater is provided with a heating through hole, and the heater is coupled to the left semi-convex and the right semi-convex through the heating through hole.

The use of such a plastic pipe forming device has the following advantages:

1. With this structure, the workpiece can be clamped by the cylinder to push the left clamping seat, and then heated by the heater, and then the cylinder 2 pushes the forming head to shape the plastic tube; the labor intensity of the worker is greatly reduced, and the labor intensity is greatly improved. Processing efficiency

2. Since the inner wall of the left half boss is provided with a pressure sensor, when the pressure detected by the pressure sensor is greater than the set pressure value during clamping, the cylinder can be intelligently stopped by the controller.

Among them are: 1. Workbench; 2. Pole; 3. Crossbar; 4. Cylinder one; 5. Left clamping seat; 6. Right clamping seat; 7. Left half boss; 8. Right half boss ; 9. Pressure sensor; 10. Cylinder 2; 11. Forming head; 12. Heater; 13. Controller.

detailed description

The plastic pipe forming device shown in Fig. 1 comprises a workbench, and a work stand has a vertical rod and a controller. The work table is provided with a laterally movable left clamping seat and a fixed right clamping seat, and the vertical rod side Connect the cylinder one, the cylinder one is connected with the left clamping seat, the left clamping seat and the right clamping seat are on the same straight line, the upper end of the vertical rod is connected with the cross bar, the lower end of the horizontal bar is connected with the cylinder 2, the lower end of the cylinder is connected with the forming head, left The clamping seat is provided with a left half boss, the right clamping seat is provided with a right half boss, and the left half boss and the right half boss form a clamping mouth, and the left half boss inner wall is provided with a pressure sensor, the left half The outside of the boss and the outside of the right half of the boss are sleeved with a heater. The nipple, the heater and the forming head are on the same center line, and the heater, the cylinder one, the cylinder two, and the pressure sensor are respectively connected to the controller.

The controller is a PLC controller.

During molding, the workpiece is first placed in the jaw, and the left clamping seat is moved to the right clamping seat by the clamping cylinder to clamp the workpiece to reduce the clamping position. When clamping, when the pressure sensor is on the inner wall of the left clamping seat When the sensed pressure value exceeds the set value, the pressure sensor transmits a signal to the controller, and the controller controls the cylinder to stop running, and then the heater is sleeved on the left half boss and the right half boss, and the pair is located in the heating pass.
