[0002] When punching a pipe, a mandrel is often used as a supporting structure for the pipe, that is, the pipe to be punched is first inserted into the mandrel, and then the punch is pressed down to punch the pipe. Generally speaking, one end of the mandrel is suspended, so after the punch is pressed down for a long time, the suspended end of the mandrel is easily skewed due to the downward pressure, affecting the stability of the punching of the pipe. Summary of the invention

[0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the utility model provides a stabilizing mechanism for pipe punching, which can prevent the core rod from tilting during the pipe punching process, so as to improve the stability of the pipe punching.

[0004] Technical solution: To achieve the above-mentioned purpose, the utility model provides a stabilizing mechanism for punching pipe fittings, comprising a punch, a core rod and a pipe fitting to be punched; the core rod is provided with a through hole opposite to the punch, and after the pipe fitting is inserted into the core rod, the displacement of the punch toward the through hole can punch the pipe fitting; one end of the core rod is suspended, and a movable support block is provided at the suspended end of the core rod, and a cushion block is provided below the movable support block; a push plate is provided on the path for the pipe fitting to be inserted into the core rod, and the push plate is connected to the cushion block; the push plate is pushed during the process of the pipe fitting being inserted into the core rod, and the pushed push plate can pull the cushion block to raise the movable support block, so that the raised movable support block supports the suspended end of the core rod.

[0005] Furthermore, the cushion block is connected to the push plate via a connecting rod, the connecting rod is consistent with the length direction of the core rod, and the connecting rod is displaced along the length direction of the core rod under the guidance of the guide rail.

[0006] Furthermore, one end of the connecting rod extends from below the movable support block and connects to the cushion block, which has a raised slope.

BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Attached Figure 1 It is a schematic diagram of the overall structure of the utility model;

[0012] Attached Figure 2 It is a structural schematic diagram of the elevated slope and the squeezed slope. DETAILED DESCRIPTION

[0013] The utility model is further described below in conjunction with the accompanying drawings.

[0014] As attached Figures 1 to 2 The stabilizing mechanism for punching pipe fittings comprises a punch 1, a core rod 2 and a pipe fitting 3 to be punched. The core rod 2 has a through hole 4 opposite to the punch 1, the outer contour of the core rod 2 is consistent with the inner contour of the pipe fitting 3, and the pipe fitting 3 can be inserted into the core rod 2. After the pipe fitting 3 is inserted into the core rod 2, the lifting mechanism drives the punch 1 to move downward, and the displacement of the punch 1 toward the through hole 4 can punch the pipe fitting 3, and the debris generated by the punching can fall out of the through hole 4.

[0015] One end of the mandrel 2 is suspended, and there is a movable support block 5 below the suspended end of the mandrel 2. There is a gap between the movable support block 5 and the suspended end of the mandrel 2, and the pipe fitting 3 is inserted into the mandrel 2 from the gap. There is a cushion block 6 below the movable support block 5. There is a push plate 7 on the path of the pipe fitting 3 being inserted into the mandrel 2, and the push plate 7 is connected to the cushion block 6. In the process of the pipe fitting 3 being inserted into the mandrel 2, the pipe fitting 3 will push the push plate 7. Since the push plate 7 is connected to the cushion block 6, the pushed push plate 7 can pull the cushion block 6 and move the cushion block 6 to the bottom of the movable support block 5, thereby raising the movable support block 5, so that the raised movable support block 5 can support the suspended end of the mandrel 2. Therefore, the mandrel 2 is not easy to be skewed during the punching process of the pipe fitting 3, thereby improving the stability of the punching of the pipe fitting 3.

[0016] The cushion block 6 is connected to the push plate 7 via a connecting rod 8, and the connecting rod 8 is consistent with the length direction of the core rod 2. Figure 1 As shown in the figure, the bottom plate 14 is provided with a guide rail 9, the connecting rod 8 is slidably matched with the guide rail 9, and the connecting rod 8 is displaced along the length direction of the mandrel 2 under the guidance of the guide rail 9. When the push plate 7 is pushed by the pipe 3, the push plate 7 pulls the cushion block 6 to displace through the connecting rod 8.

[0017] One end of the connecting rod 8 extends from the bottom of the movable support block 5 and connects to the cushion block 6. The cushion block 6 has a raised slope 10, which is located on one side of the upper end of the cushion block 6 and faces the movable support block 5. When the pull rod pulls the cushion block 6 to move toward the movable support block 5, the cushion block 6 squeezes into the bottom of the movable support block 5 through the raised slope 10, thereby raising the movable support block 5.

[0018] The bottom of the movable support block 5 has a squeezed slope 11, which is opposite to the raised slope 10. Figure 2 In an embodiment, the squeezed slope 11 and the raised slope 10 are both inclined surfaces. Due to the interaction between the squeezed slope 11 and the raised slope 10, the cushion block 6 is more easily squeezed into the bottom of the movable support block 5 to raise the movable support block 5.

[0019] The movable support block 5 is mounted on the guide seat 12, and the guide seat 12 includes two vertical rails arranged opposite to each other. The two sides of the movable support block 5 are respectively slidably matched with the two vertical rails, so that the movable support block 5 can be lifted and slid along the guide seat 12. When the movable support block 5 is raised by the cushion block 6, the movable support block 5 moves up along the guide seat 12 to support the suspended end of the core rod 2.

[0020] The push plate 7 is connected with a resetting elastic member 13. When the pipe 3 pushes the push plate 7, the resetting elastic member 13 is deformed. When the pipe 3 is pulled out of the mandrel 2, the resetting elastic member 13 rebounds and pushes the cushion block 6 away from the movable support block 5. Figure 1 In one embodiment, a vertical plate 15 is provided on the bottom plate 14, one end of the core rod 2 is a suspended end, and the other end of the core rod 2 is fixed on the vertical plate 15, and a reset elastic member 13 is connected between the vertical plate 15 and the push plate 7. When the pipe fitting 3 is inserted into the core rod 2, the reset elastic member 13 is compressed. After the pipe fitting 3 is pulled out from the core rod 2, the reset elastic member 13 extends and pushes the cushion block 6 away from the bottom of the movable support block 5.

[0021] The upper end of the movable support block 5 has an arc groove 16. In one embodiment, the pipe 3 to be punched is shorter than the mandrel 2. After the movable support block 5 is raised, the arc groove 16 on the movable support block 5 directly supports the suspended end of the mandrel 2. In another embodiment, the pipe 3 to be punched is longer than the mandrel 2. After the movable support block 5 is raised, the arc groove 16 on the movable support block 5 abuts against the section of the pipe 3 sleeved on the suspended end of the mandrel 2, thereby supporting the suspended end of the mandrel 2.

[0022] One working mode of the utility model is as follows: the pipe fitting 3 is inserted into the mandrel 2, and the push plate 7 is pushed during the insertion of the pipe fitting 3. The push plate 7 pulls the cushion block 6 through the connecting rod 8, so that the cushion block 6 is squeezed under the movable support block 5. The movable support block 5 is raised by the cushion block 6 to support the suspended end of the mandrel 2, so that the mandrel 2 is not easily distorted when the pipe fitting 3 is punched, so as to improve the stability of the punching of the pipe fitting 3. After the pipe fitting 3 is inserted into the mandrel 2, the pipe fitting 3 is held by hand to determine the punching position, and then the punch 1 is moved down to punch the pipe fitting 3. After the punching is completed, the pipe fitting 3 is pulled out, and the debris generated by the punching falls out from the through hole 4. The reset elastic member 13 is extended and pushes the cushion block 6 away from the bottom of the movable support block 5, so that the movable support block 5 is separated from the suspended end of the mandrel 2.

[0023] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
