Description

Technical Field

[0001] The utility model belongs to a vertical punching device for thin and long pipe fittings, belonging to the processing technology of gas pipes, and is used to solve the problem that the accuracy of nozzle installation holes is not up to standard when punching thin and long gas pipe fittings. Background Art

[0002] A plurality of nozzles are installed on a gas pipe assembly. As Figure 5 shown, the gas pipe is a thin and long pipe fitting with a wall thickness of 0.6 - 2.5 mm and a length of 400 - 500 mm. The prerequisite for the installation operation of the nozzle is that punching, hole flanging, and tapping need to be carried out on the pipe fitting in sequence. The nozzle is self-sealed in the internal thread hole through an external thread. When punching, since the pipe fitting is a thin and long pipe fitting, if such a pipe fitting is directly punched, it is easy to cause deformation of the pipe fitting; once the pipe fitting is deformed during the punching process, which affects the punching accuracy not reaching the standard, it will lead to quality problems such as nozzle air leakage. At the same time, most of the existing punching operations are manual operations, and the positioning accuracy cannot be effectively controlled, which further causes problems such as eccentricity of the punched holes or an angular difference from the designed position. Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is: the problem that the accuracy of nozzle installation holes is not up to standard when punching thin and long gas pipe fittings.

[0004] In order to solve the above technical problems, the inventor of the utility model obtained the technical solution of the utility model through practice and summary. The utility model adopts the following technical scheme:

[0005] A vertical punching device for thin and long pipe fittings, including a base, on which a pipe fitting angle positioning structure and a punching assembly are installed. The punching assembly includes a punching frame, a guiding frame, and an internal support rod;

[0006] A punching member and a driving body are installed on the punching frame;

[0007] Two groups of guiding frames are provided, which are symmetrically distributed on both sides of the pipe fitting respectively. The two guiding frames are located at the bottom of the punching frame, and a guiding groove is provided on the opposite side for the vertical guiding of the driving body. Two symmetrically distributed pipe fitting bottom support blocks are slidably arranged inside the guiding frames;

[0008] When the driving body moves downward, the pipe fitting bottom support blocks approach each other to support the pipe fitting from the bottom;

[0009] The internal support rod is horizontally arranged and one end of it is inserted into the pipe fitting, and a through hole adapted to the punching member is provided on the internal support rod.

[0010] Preferably, one end of the internal support rod is inserted into the pipe fitting, and the other end is provided with a mounting seat, and the mounting seat is fixed on the base.

[0011] Preferably, the pipe fitting angle positioning structure includes a top side positioning block and a bottom side positioning block. The top side positioning block is used to support and position the bottom side of the top of the pipe fitting. A positioning pin is installed on the bottom side positioning block, and the positioning pin is used to be inserted into the punched hole in the pipe fitting.

[0012] Preferably, on the top of the opposite sides of the two pipe fitting bottom support blocks, there is a first guiding inclined surface;

[0013] On the bottom of the driving body, there is a second guiding inclined surface adapted to the first guiding inclined surface.

[0014] Preferably, on the opposite sides of the two pipe fitting bottom support blocks, a reset member is installed on each side, and the free end of the reset member is connected to the inner wall of the guiding frame.

[0015] Preferably, on the bottom of the two pipe fitting bottom support blocks, there are ear plates, and on the bottom of the guiding frame, there is a horizontally arranged guiding groove, and the ear plates are slidably matched in the guiding groove.

[0016] Preferably, on the top of the opposite sides of the two pipe fitting bottom support blocks, there is an arc section structure.

[0017] Preferably, on the base, along the direction of the internal support rod arrangement, there is a sliding groove, and in the sliding groove, a sliding block is installed. The sliding block is fixedly installed on the bottom of the guiding frame. The punching frame is adjustable in position relative to the base along the direction of the internal support rod arrangement. Compared with the prior art, the present utility model has the following beneficial effects:

[0018] 1. In the present utility model, the pipe fitting is supported from the inside by the internal support rod, and the angle of the pipe fitting is precisely controlled through the positioning structure. At the same time, since both the inside and the outside are supported, when punching the pipe fitting, deformation will not occur, thereby ensuring that the punching accuracy is guaranteed. The reason for setting the internal and external supports is as follows: The free end of the internal support rod lacks support. Once pressure is applied to the relatively long pipe fitting, it is prone to deformation. When deformation occurs and pressure is continuously applied, it will cause the end of the internal support rod to bear pressure, and when the arm moment is too large, the internal support rod will break or the through hole on the punch and the internal support rod cannot be aligned, and thus the punching operation cannot be completed.

[0019] 2. In the present utility model, a driving body is arranged on the punching frame, and by driving the driving body to move downward to drive the pipe fitting bottom support blocks to approach each other, the linkage of the components is realized, thereby realizing the bottom support of the pipe fitting and ensuring the punching accuracy and quality.

[0020] 3. In the present utility model, by arranging a sliding groove on the base and adjusting the position of the guiding frame along the direction of the internal support rod arrangement, continuous multiple nozzle mounting holes on the pipe fitting can be achieved. Description of the Drawings
