Description

Technical Field

[0001] This utility model relates to the technical field of cutting off excess sections of gas pipe joints, and in particular to a cutting device for cutting off excess sections of gas pipe joints. Background Technology

[0002] A gas pipe connector 1 is formed by hot pressing using a molding die. The gas pipe connector 1 is made of elastic rubber material and is cylindrical in shape, with a central hole 2 formed inside, coaxial with the cylindrical shape. The structure of the gas pipe connector 1 is as follows: Figures 1-2 As shown. Due to manufacturing process limitations, the length of the formed gas pipe connector 1 is too long, meaning its length does not meet design requirements. Therefore, workers need to cut off the excess section of the gas pipe connector 1 to obtain a finished product with the specified length.

[0003] The method used by the workers in the workshop to cut off the excess section of gas pipe connector 1 is as follows:

[0004] S1, the worker takes out a... Figures 1-2 As shown in the gas pipe connector 1, use a vernier caliper to measure the length H of the excess section on the gas pipe connector 1, such as... Figure 3 As shown, then draw a circular line on the cylindrical surface of the gas pipe connector 1 with a pen;

[0005] S2. The worker holds the lower end of the gas pipe connector 1 with his left hand, and then holds the scissors with his right hand, aligning the blades of the scissors with the circular line of the gas pipe connector 1, and then closes the two handles of the scissors to cut off the excess section of the gas pipe connector 1, thereby obtaining a finished product with the specified length.

[0006] S3. Workers put the finished products into the collection basket to collect them.

[0007] S4. Workers repeat steps S1 to S3 multiple times to cut off the excess sections of all gas pipe joints 1 in the workshop and obtain multiple finished products of the specified length in the receiving basket.

[0008] However, although the method used in the workshop can cut off the excess section of gas pipe connector 1, it still has the following technical defects:

[0009] In step S1, the worker needs to draw a circular line on the cylindrical surface of the gas pipe connector 1. The location of this circular line is the cutting position of the scissors. In step S2, the worker also needs to use the scissors to cut the gas pipe connector 1 from the circular line to obtain a finished product of the specified length. In step S3, the worker also needs to manually put the finished product into the receiving basket. The entire operation is done manually by the worker, which not only increases the worker's workload but also involves many steps, resulting in a long time required to obtain a finished product in the receiving basket, thus reducing the cutting efficiency of the gas pipe connector 1.

[0010] Therefore, there is an urgent need for a cutting device that can greatly reduce the workload of workers and greatly improve the efficiency of cutting gas pipe joints. Utility Model Content

[0011] The purpose of this invention is to overcome the shortcomings of the prior art and provide a cutting device for cutting off excess sections of gas pipe joints, which greatly reduces the workload of workers and greatly improves the efficiency of cutting gas pipe joints.

[0013] The pad is also provided with a cutting assembly located on the left side of the turntable for cutting off the excess section of the gas pipe connector. The cutting assembly includes a vertical plate fixed to the top surface of the pad, a mounting plate connected to the top of the vertical plate, a double-acting cylinder fixed to the bottom surface of the mounting plate, and a connecting plate fixed to the working end of each of the two piston rods of the double-acting cylinder. Both connecting plates extend downwards, and a cutter is fixed to the inner end face of the extended end. The blades of both cutters are flush with the top surface of the positioning column on the left side.

[0014] The diameter of the through hole in the unloading plate is equal to the diameter of the positioning post.

[0015] The two servo motors are symmetrical about the stepper motors, and the two positioning columns are also symmetrical about the stepper motors.

[0016] A fixing plate is fixedly connected to the unloading plate, and the fixing plate is fixed on the piston rod of the unloading cylinder.

[0017] A receiving basket is placed on the top surface of the pad, and the receiving basket is located directly below the two cutters.

[0038] The present invention will be further described below with reference to the accompanying drawings. The scope of protection of the present invention is not limited to the following description:

[0039] like Figures 4-8 As shown, a cutting device for trimming excess sections of a gas pipe connector includes a pad 3, a stepper motor 4 fixed to the top surface of the pad 3, a turntable 5 fixed to the output shaft of the stepper motor 4, and servo motors 6 fixed to the top surface of the turntable 5 at its left and right ends. The two servo motors 6 are symmetrical about the stepper motor 4, and two positioning posts 8 are symmetrical about the stepper motor 4. An L-plate 7 located outside the turntable 5 is fixed to the output shaft of each of the two servo motors 6. A positioning post 8 is fixed to the top surface of the horizontal portion of the L-plate 7. The diameter of the positioning post 8 is smaller than the inner diameter of the gas pipe connector 1. A discharge cylinder 9 is fixed to the bottom surface of the horizontal portion of the L-plate 7. The piston rod of the discharge cylinder 9 extends upward through the horizontal portion of the L-plate 7, and a discharge plate 10 is fixed to its extended end. A through hole 11 is opened in the discharge plate 10, and the discharge plate 10 is sleeved on the outside of the positioning post 8 through the through hole 11. The diameter of the through hole 11 of the discharge plate 10 is equal to the diameter of the positioning post 8.

[0040] The pad 3 is also provided with a cutting assembly 12 located on the left side of the turntable 5 for cutting off the excess section of the gas pipe connector 1. The cutting assembly 12 includes a vertical plate 13 fixed on the top surface of the pad 3. A mounting plate is connected to the top of the vertical plate 13. A double-acting cylinder 14 is fixed on the bottom surface of the mounting plate. A connecting plate 15 is fixed on the working end of the two piston rods of the double-acting cylinder 14. Both connecting plates 15 extend downward, and a cutter 16 is fixed on the inner end face of the extended end. The blades of the two cutters 16 are flush with the top surface of the positioning post 8 on the left side.

[0041] A fixing plate 17 is fixedly connected to the unloading plate 10, and the fixing plate 17 is fixed to the piston rod of the unloading cylinder 9. A receiving basket 18 is placed on the top surface of the pad plate 3, and the receiving basket 18 is located directly below the two cutters 16.

[0042] The cutting device also includes a controller, which is electrically connected to the unloading cylinder 9, the double-acting cylinder 14, the stepper motor 4, and the servo motor 6 via signal lines. The operator can control the extension or retraction of the piston rods of the unloading cylinder 9 and the double-acting cylinder 14 through the controller, and at the same time control the start or stop of the stepper motor 4 and the servo motor 6, thereby facilitating the operator's operation.

[0043] The working process of this utility model is as follows:

[0044] S1, the worker takes out a... Figures 1-2 The gas pipe connector 1 to be cut is shown. The center hole 2 of the gas pipe connector 1 is fitted onto the positioning post 8 on the right side from top to bottom, ensuring that the bottom surface of the gas pipe connector 1 is in contact with the top surface of the unloading plate 10, thus achieving the positioning of the gas pipe connector 1. Figure 9 As shown, at this time, the excess section of the gas pipe connector 1 is just exposed outside the positioning post 8;

[0045] S2. The stepper motor 4 is started, driving the turntable 5 to rotate on the horizontal plane. The turntable 5 drives the servo motor 6, unloading cylinder 9, unloading plate 10, and positioning column 8 on it to rotate synchronously on the horizontal plane, thereby driving the gas pipe connector 1 to rotate synchronously. When the gas pipe connector 1 has rotated 180° on the horizontal plane, the controller controls the stepper motor 4 to turn off. At this time, the gas pipe connector 1 just enters the cutting station of the cutting assembly 12. Figure 10 As shown, the excess section of the gas pipe connector 1 is located on the left and right sides of the two cutters 16 of the cutting assembly 12.

[0046] S3. Control the retraction of the two piston rods of the double-acting cylinder 14. The piston rods drive the cutter 16 to move towards the gas pipe connector 1. When the two piston rods of the double-acting cylinder 14 are fully retracted, the two cutters 16 just cut off the excess section of the gas pipe connector 1. Figure 11 As shown, after cutting off the excess section of the gas pipe connector 1, a finished product 19 with the specified length can be obtained;

[0047] S4. Push the finished product 19 into the receiving basket 18. The specific operation steps are as follows:

[0048] S41, the two piston rods of the double-acting cylinder 14 extend outward, driving the cutter 16 to move outward. The cutter 16 moves away from the finished product 19. Figure 12 As shown;

[0049] S42. The servo motor 6 is started, driving the L-plate 7 to rotate downwards. The L-plate 7 then drives the unloading cylinder 9, unloading plate 10, and positioning column 8 to rotate downwards synchronously, thereby causing the finished product 19 to rotate downwards. When the finished product 19 has rotated 180° downwards, the controller controls the servo motor 6 to turn off. At this time, the finished product 19 is facing the receiving basket 18. Figure 13 As shown;

[0050] S43. The piston rod of the control unloading cylinder 9 extends downward, and the piston rod drives the unloading plate 10 to move downward along the positioning post 8. During the movement, the unloading plate 10 gradually pushes the finished product 19 downward, such as... Figure 14 As shown; when the piston rod of the unloading cylinder 9 is fully extended, the finished product 19 can be pushed off the positioning column 8, and the pushed-out finished product falls into the receiving basket 18, thus finally realizing the cutting of the first gas pipe connector 1.

[0051] S5. Workers repeat steps S1 to S4 multiple times to cut off the excess sections of all gas pipe joints 1 in the workshop and obtain multiple finished products of the specified length in the receiving basket.

[0052] As can be seen from steps S1 to S4, the worker only needs to first put the gas pipe connector 1 onto the positioning post 8 on the right side; then start the stepper motor 4 to make the gas pipe connector 1 enter the cutting station of the cutting component 12; then control the two piston rods of the double-acting cylinder 14 of the cutting component 12 to retract, thereby cutting off the excess section of the gas pipe connector 1 to obtain the finished product 19 that meets the specified length; finally, through the linkage of the servo motor 6 and the unloading cylinder 9, the finished product can be pushed into the receiving basket 18 to collect the finished product 19 in the receiving basket 18.

[0053] Therefore, it can be seen that during the entire cutting process, there is no need for workers to draw a circular line on the cylindrical surface of the gas pipe connector 1, nor is it necessary for workers to cut the gas pipe connector 1 from the circular line with scissors, nor is it necessary for workers to manually put the finished product into the receiving basket. Instead, the excess section of the gas pipe connector 1 is automatically and quickly cut off, and the cut finished product 19 is automatically pushed into the receiving basket 18. This not only greatly reduces the workload of workers, but also greatly improves the cutting efficiency of the gas pipe connector 1.

[0054] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
