Description

Technical Field

[0001] The utility model relates to the technical field of pipeline and pipe fitting processing, in particular to a cutting device for pipeline and pipe fitting processing which is convenient for positioning. Background Art

[0002] Pipe fittings are a general term for parts and components in pipeline systems that play the role of connection, control, direction change, diversion, sealing, support, etc. Most of the pipe fittings are made by cutting the main pipe and then processing it. Therefore, cutting equipment is widely used in the field of pipe fitting processing. However, most of the existing cutting equipment is only convenient for clamping and limiting on one side. As the cutting proceeds, the pipe on the other side is prone to move, which can easily cause accidental injury. In addition, the cutting length needs to be measured before cutting, and the cutting accuracy needs to be improved. Therefore, a cutting equipment for pipe fitting processing with high cutting stability and high cutting accuracy and convenient positioning is designed. Utility Model Content

The two groups of clamping friction rollers are arranged in the same direction as the one-way guide mechanism, and the gantry is provided with a lifting and adjusting component for synchronously lifting and lowering the two groups of clamping friction rollers.

[0011] (III) Beneficial effects

[0012] Compared with the prior art, the utility model provides a cutting device for pipe fitting processing that is convenient for positioning, and has the following beneficial effects:

[0013] The cutting device for processing pipes and pipe fittings that is easy to position can facilitate the transportation of the pipe to the side with the limiting mechanism through the one-way guiding support mechanism. The limiting mechanism can be used to initially limit the pipe to prevent it from continuing to be transported. Then, after contacting the limit of the limiting mechanism, the moving distance of the pipe can be detected by the displacement measuring sensor, so that the length of the pipe moved out of the cutting mechanism can be calculated. After moving to the required cutting position, the displacement measuring sensor transmits a signal to the two groups of upper clamping mechanisms, so that the two groups of upper clamping mechanisms can press the pipe from the upper side downward and cooperate with the one-way guiding support mechanism. Then, the pipe can be cut by the cutting mechanism in the two groups of upper clamping mechanisms. When cutting, it is convenient to press both sides of the cutting position, thereby improving the cutting stability. At the same time, the cooperation between the displacement measuring sensor and the two groups of upper clamping mechanisms improves the cutting accuracy. The cutting device for processing pipes and pipe fittings that is easy to position has high cutting stability and high cutting accuracy. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Example:

[0021] See also Figure 1-4 A cutting device for pipe fitting processing with convenient positioning includes an operating table 1. Upper clamping mechanisms are arranged on both sides of the top of the operating table 1. A cutting mechanism is arranged between the two sets of upper clamping mechanisms. It also includes a limiting mechanism arranged on one of the upper clamping mechanisms. A one-way guiding support mechanism that can be transported to the limiting mechanism side is arranged through the bottom of the two sets of upper clamping mechanisms. A displacement measuring sensor 5 is arranged below the limiting mechanism. Both sets of upper clamping mechanisms are electrically connected to the displacement measuring sensor 5.

[0022] Specifically, the upper clamping mechanism includes a gantry 6 fixedly mounted on the operating table 1, and two groups of clamping friction rollers 2 are arranged at the bottom of the gantry 6, which are symmetrical on the left and right and above the one-way guide support mechanism. The two groups of clamping friction rollers 2 are arranged in the same direction as the one-way guide mechanism. The gantry 6 is provided with a lifting and adjusting component for synchronously lifting and lowering the two groups of clamping friction rollers 2. Through the lifting and adjusting component, it is convenient to drive the two groups of clamping friction rollers 2 to lift and lower at the same time. Through the two groups of clamping friction rollers 2, it is convenient to clamp the left and right sides of the pipeline from the top and place it on the one-way guide mechanism to continue moving forward.

[0023] Specifically, the limiting mechanism includes a limiting roller 4 arranged between two groups of pressing friction rollers 2 on a group of upper pressing mechanisms, and a fixing bar 7 is fixedly installed above the two groups of pressing friction rollers 2 through a lifting frame 8, and the fixing bar 7 is connected to the lifting adjustment component. The top of the limiting roller 4 is guided and slidably matched with the fixing bar 7 through a guide slide 17, and a top bar 18 is fixedly installed on the top of the guide slide 17. A spring 19 is arranged between the bottom of the top bar 18 and the fixing bar 7, and further, the two ends of the spring 19 are fixedly connected to the top bar 18 and the fixing bar 7 respectively, and the guide slide 17 is used to guide the fixing bar 7. , the top bar 18 and the spring 19 are arranged to facilitate the limit roller 4 to perform the pressing operation on the pipeline when the pressing mechanism performs the pressing operation, thereby improving the pressing stability of the pressing mechanism. Furthermore, the lifting and adjusting assembly includes two groups of driving cylinders 9 symmetrically installed on both sides of the gantry 6, and the top output ends of the two groups of driving cylinders 9 are fixedly connected to the fixed bar 7. Furthermore, the pressing friction roller 2 is rotatably connected to the lifting frame 8, which facilitates the lateral rotation of the pressing friction roller 2, and the limit roller 4 is rotatably connected to the guide slide 17, which facilitates the lateral rotation of the limit roller 4.

[0024] Specifically, the cutting mechanism includes a cutting blade 3, a connecting plate 10 is fixedly connected between the two groups of gantries 6, a lifting frame 12 is provided on the connecting plate 10 which is lifted and slidably cooperated by a driving cylinder 11, a cutting motor 13 is fixedly installed at the bottom of the lifting frame 12, and the cutting blade 3 is fixedly installed on the output shaft of the cutting motor 13. Starting the cutting motor 13 facilitates the rotation of the cutting blade 3, and extending the output shaft of the driving cylinder 11 facilitates the downward transportation of the cutting blade 3, so that the pipeline can be cut, and the cut pipeline can be turned over for preparing pipeline fittings.

[0025] Specifically, the one-way guiding support mechanism includes a plurality of stinger racks 14 spaced apart on the operating table 1, the stinger racks 14 are symmetrically provided with two groups of guide rollers 15 inclined downwardly toward the middle, and one-way intermittent motion mechanisms 16 are further provided on both sides of the two groups of guide rollers 15. The arrangement of the stinger racks 14 and the two groups of guide rollers 15 facilitates the centering and guiding of the pipeline, and the arrangement of the one-way intermittent motion mechanism 16 enables the two guide rollers 15 to move one-way to prevent them from reversing and moving back the pipeline. Furthermore, the one-way intermittent motion mechanism 16 can be set to a ratchet mechanism consisting of a ratchet and a pawl.

[0026] When in use, the pipeline is placed on the one-way guide support mechanism from the side of the unlimited mechanism, and then the upper clamping mechanism on the limiting mechanism side drives the limiting mechanism to limit the one-way direction of the pipeline. When the pipeline reaches the limiting mechanism, the displacement measurement sensor 5 is started, and then contacts the limit of the limiting mechanism, and the pipeline continues to be transported. After moving to the required length, the displacement measurement sensor 5 transmits a signal to the two groups of upper clamping mechanisms, and the pipeline is clamped by the two groups of upper clamping mechanisms, and then the cutting mechanism is started to cut the pipeline. After cutting, the clamping of the two groups of upper clamping mechanisms is released, and the pipeline is continued to be pushed forward, and the cut pipeline is pushed out from the one-way guide support mechanism, and then the above operation is repeated.
