Description

Technical Field

[0001] The present application belongs to the technical field of copper tube processing, and in particular relates to a copper tube combined drawing device with convenient automatic shutdown. Background Art

[0002] Drawing is a plastic processing method that deforms a metal blank by passing it through the die hole of a drawing die. During the drawing process, the blank undergoes plastic deformation in the drawing die. After passing through the drawing die, the cross-sectional shape and size of the blank are the same as those at the die hole outlet of the drawing die. Therefore, by changing the shape and size of the die hole of the drawing die, the corresponding drawn product can be obtained. The copper tube is drawn using a combined drawing device.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments.

[0023] REFERENCE Figure 1-4A convenient automatic shutdown type copper tube joint drawing device includes a processing base plate 1, and two groups of support legs 2 are fixedly connected to the bottom surface of the processing base plate 1. The bottom end of each group of support legs 2 is fixedly connected to a lower support plate 3. The two groups of support legs 2 and the lower support plate 3 are used to form a support structure to enable the copper tube joint drawing device to be stably supported in the required position for use.

[0024] The upper surface of the processing base plate 1 is fixedly connected to a fixed heating box 4, and both sides of the fixed heating box 4 are fixedly connected to a drive motor 8. The drive motor 8 can determine the time of automatic shutdown for precise sizing through communication with the operator through an implanted program, and the equipment is automatically shut down after 5 minutes of no movement. When the machine is not driven, the start and stop of the equipment can be achieved through a manual button. If there is no sawing action within 5 minutes after manual start of the equipment, the equipment will automatically shut down. When the equipment is driven normally, the precise sizing shutdown is not allowed, and the manual stop button is shielded to prevent the saw blade from being damaged by the pipe being stuck. When there is no sawing action within 5 minutes after the equipment is normally shut down, the precise sizing will automatically shut down when there is no pipe on the equipment. The simulation test of the program achieves the above requirements without affecting other parts. After uploading the program to the PLC of the equipment, the whole machine is debugged and runs normally. The output end of each drive motor 8 is fixedly connected to a rotating screw 9. The drive motor 8 is controlled by the PLC controller, which can conveniently use the convenient automatic shutdown type copper tube combined drawing device to draw the copper tube.

[0025] The inner wall of the fixed heating box 4 is fixedly connected with a fixed clamping hydraulic rod 7, and the telescopic end of the fixed clamping hydraulic rod 7 is fixedly connected with a clamping frame 22. The interior of the fixed heating box 4 is provided with drawing dies 6 arranged at equal distances, and the outer surface of each drawing die 6 is in contact with the bottom surface of the clamping frame 22. The upper surface of the fixed heating box 4 is provided with an oiling groove 5, and the outer surface of each drawing die 6 is provided with connecting grooves 19 arranged at equal distances, and each group of connecting grooves 19 is connected to the oiling groove 5. By utilizing the oiling grooves 5 opened on the fixed heating box 4, it is possible to conveniently apply drawing oil to the copper tube blank through the connecting grooves 19 before drawing.

[0026] A die hole 20 is provided on the front of each drawing die 6, and a movable frame 15 is provided above the processing base plate 1. The outer surface of each rotating screw 9 is threadedly connected to a movable block 12, and the side surfaces of the two movable blocks 12 close to each other are fixedly connected to the two side surfaces of the movable frame 15 respectively. The bottom surface of each movable block 12 is in contact with the upper surface of the processing base plate 1. By utilizing the cooperation between the movable block 12 and the rotating screw 9, the movable block 12 can move left and right along the rotating screw 9 with the movable frame 15 by rotating the rotating screw 9.

[0027] The bottom surface of each moving block 12 is fixedly connected to a limiting slider 14, and two limiting grooves 13 are provided on the upper surface of the processing base plate 1. Each limiting slider 14 is slidably connected to the inside of the limiting groove 13. By sliding the limiting slider 14 in the limiting groove 13, the horizontal movement of the moving block 12 can be limited, thereby facilitating the use of the drawing device to draw the copper tube.

[0028] The outer surface of each rotating screw 9 is fixedly connected to a stabilizing bearing 10, the outer ring of each stabilizing bearing 10 is fixedly connected to the upper surface of the processing base plate 1, and the end of each rotating screw 9 away from the driving motor 8 is fixedly connected to a baffle 11, and the back of each baffle 11 is in contact with the front of the stabilizing bearing 10. The stabilizing bearing 10 is used to improve the rotation stability of the rotating screw 9, and the baffle 11 is used to improve the stability of the rotation of the rotating screw 9 in the stabilizing bearing 10.

[0029] The inner wall of the mobile frame 15 is fixedly connected with mobile clamping hydraulic rods 16 arranged at equal distances, and the telescopic end of each mobile clamping hydraulic rod 16 is fixedly connected with an upper clamping block 17. The inner bottom wall of the mobile frame 15 is fixedly connected with lower clamping blocks 18 arranged at equal distances. The telescopic end of the fixed clamping hydraulic rod 7 is fixedly connected with two reinforcing rods 21, and the ends of the two reinforcing rods 21 away from each other are fixedly connected to the upper surface of the clamping frame 22. The two reinforcing rods 21 are fixed between the telescopic end of the fixed clamping hydraulic rod 7 and the clamping frame 22, thereby improving the connection stability between the telescopic end of the fixed clamping hydraulic rod 7 and the clamping frame 22.

[0030] The working principle of the utility model is as follows: when in use, first connect the fixed heating box 4, the fixed clamping hydraulic rod 7, the driving motor 8 and the movable clamping hydraulic rod 16 to the power supply. When the drawing device needs to be used for the joint drawing processing of the copper tube, the drawing device is first manually set on the horizontal ground, and the support structure composed of two groups of support legs 2 and the lower support plate 3 is used to enable the drawing device to be stably set at the required position for the joint drawing processing of the copper tube. Then, the copper tube to be drawn is manually set inside the drawing die 6, and the drawing die 6 is installed inside the fixed heating box 4. Since different die holes 20 are provided on one side of the drawing die 6, different drawing dies 6 can be conveniently used to draw copper tubes of different sizes and shapes, and the heating effect in the fixed heating box 4 can be used to heat the copper tube to be processed.

[0031] Then, by controlling the power supply of the fixed clamping hydraulic rod 7 and the movable clamping hydraulic rod 16, the clamping frame 22 can be used to extrude the drawing die 6 to clamp one end of the copper tube, and the movable clamping hydraulic rod 16 is used to drive the cooperation of the upper clamping block 17 and the lower clamping block 18 to clamp the other end of the copper tube that needs to be drawn. By controlling the power supply of the driving motor 8, the two rotating screws 9 can be driven to rotate. Since the two rotating screws 9 cooperate with the moving blocks 12 on both sides of the movable frame 15 and the limit slider 14 slides in the limit slide groove 13, the movable frame 15 can be moved and drawn with one end of the copper tube. When the copper tube reaches the appropriate length, the corresponding movable clamping hydraulic rod 16 is controlled to drive the corresponding upper clamping block 17 and the lower clamping block 18 to move away, so that the copper tube is not clamped and drawn.
