Description

Technical Field

[0001] The utility model relates to the technical field of pipe cutting devices, in particular to a stainless steel pipe cutting device with a limiting function. Background Art

[0002] Stainless steel pipe is a hollow, long, round steel bar with numerous excellent properties and a wide range of applications. Processing stainless steel pipe requires cutting equipment to create pipe units of the required length. Stainless steel pipe cutting devices are specialized tools or equipment used to cut stainless steel pipe, and they come in a variety of types, each with its own unique characteristics.

[0003] The utility model with announcement number CN217799286U discloses a stainless steel pipe cutting device, which is provided with an angle adjustment component. When the stainless steel pipe needs to be cut at a special angle, the stainless steel pipe is first fixed in the existing clamping device, and the locking state of the rotating column is released by pulling the buckle outward. Then the handle rod is rotated to the required angle, and the card block is aligned with the buckle. Then, the buckle is released and pushed by the spring to buckle the buckle on the card block to complete the locking. The special angle of the stainless steel pipe can be adjusted and cut according to the special angle to meet more processing requirements, thereby achieving the effect of improving the overall practicality of the device.

[0004] However, when the above device is used, it is difficult to accurately cut pipe units of a specified length according to processing requirements. Workers need to judge the length of the pipe to be cut based on experience or with the help of tools such as a ruler before cutting. Therefore, there is a large error, which may make the cut pipe unit too short and unusable, or too long and require a second cut. In addition, using a ruler for measurement is also cumbersome. Therefore, in order to solve the above problems, a stainless steel pipe cutting device with a limiting function is proposed. Utility Model Content

[0005] The technical problem to be solved by the present invention is to provide a stainless steel pipe cutting device with a limiting function, which clamps and fixes the end of the pipe to be cut with a pipe end clamping limit frame before cutting to prevent the pipe from sliding or offsetting during cutting, and the pipe end clamping limit frame can slide along the sliding rod frame, so as to adjust the cutting length. When it is necessary to cut a pipe of a specified length, the position of the limit baffle can be adjusted according to the reference plate, that is, the maximum stroke point of the pipe end clamping limit frame, that is, the maximum cutting length of the pipe. When the pipe end clamping limit frame is slid to make it fit with the limit baffle, the pipe also moves to the cutting point of the specified length. At this time, the pipe of the specified length can be cut. The operation is simple and the cutting length is relatively accurate, which solves the technical problems in the prior art.

[0006] The technical solution adopted by the embodiment of the present application to solve the technical problem is:

[0007] The invention relates to a stainless steel pipe cutting device with a limiting function, comprising a base plate, wherein a sliding rod frame and a pipe cutting machine are fixedly arranged at the front and rear ends of the upper end face thereof, respectively. The pipe cutting machine is used for cutting pipes. The pipe end clamping and limiting frame is slidably arranged on the sliding rod frame, and is used for clamping and fixing the end of the pipe to be cut to prevent the pipe from sliding or deflecting during cutting. The pipe end clamping and limiting frame can slide along the sliding rod frame, thereby realizing adjustment of the cutting length. The limiting baffle is slidably arranged on the sliding rod frame and is located in front of the pipe end clamping and limiting frame to limit the maximum stroke of the pipe end clamping and limiting frame. A reference plate is fixedly arranged on the base plate, which serves as a reference for judging the current position of the limiting baffle. When it is necessary to cut a pipe of a specified length, the position of the limiting baffle can be adjusted according to the reference plate, that is, the maximum cutting length of the pipe. When the sliding pipe end clamping and limiting frame is aligned with the limiting baffle, the pipe also moves to the cutting point of the specified length, and the pipe of the specified length can be cut.

[0008] In one possible implementation, the sliding rod frame includes two groups of symmetrically arranged end fixing plates, and a sliding rod is fixedly connected between each group of end fixing plates. The sliding rod provides the necessary structural basis for the sliding connection between the pipe end clamping limit frame and the limit baffle, and the end fixing plate can suspend the sliding rod to ensure that it can perform its normal function.

[0009] In one possible implementation, the limit baffle includes a sliding ring that is slidably mounted on the sliding rod, and the sliding rings are fixedly connected by a cross-connecting plate. The cross-connecting plate can block the pipe end clamping limit frame and limit its maximum stroke, while the sliding ring is used to realize the sliding connection between the cross-connecting plate and the sliding rod.

[0010] In one possible implementation, a locking groove is provided on the sliding rod, and the locking groove is arranged along the length direction of the sliding rod. At the same time, a bolt locking piece is threadedly connected to the sliding ring, and when the bolt locking piece is tightened, its bottom end is in close contact with the locking groove. When the position adjustment of the limit baffle is completed, the bolt locking piece is tightened. At this time, the position of the limit baffle is fixed and cannot continue to slide, ensuring that it can play a reliable limiting role on the pipe end clamping limit frame, avoiding it from sliding after being hit by the pipe end clamping limit frame, causing the maximum cutting length of the pipe to change.

[0011] In one possible implementation, a bending pointer is fixedly connected to the side of the sliding ring, and a number of scale grooves are opened on the reference plate. Corresponding scale lines are drawn in the grooves, and the tip of the bending pointer points to the corresponding scale line. During the movement of the bending pointer, the corresponding scale line reading also changes synchronously. The operator can judge the current position of the limit baffle based on this, so that he can adjust the position of the limit baffle more accurately, thereby ensuring the accuracy of the cutting length.

[0012] In one possible implementation, the pipe end clamping limit frame includes a lower clamping seat, and sliding sleeves slidably mounted on the sliding rod are fixedly connected on both sides of the lower clamping seat. A door frame is fixedly arranged on the lower clamping seat, and an upper clamping plate is slidably arranged in the door frame, and an adjusting threaded rod is threadedly connected to the door frame. The bottom end of the adjusting threaded rod is rotatably connected to the upper clamping plate. When the adjusting threaded rod is twisted, it will drive the upper clamping plate to move up and down, and then the clamping action of the upper clamping plate and the lower clamping seat is used to clamp and fix the end of the pipe fitting.

[0013] In one possible implementation, an adjusting handwheel is fixedly connected to the top end of the adjusting threaded rod, which can facilitate the operator to rotate the adjusting threaded rod by twisting it. A guide rod is fixedly connected to the upper clamping plate, which passes through the door frame and is in sliding contact with it. The guide rod can guide the movement of the upper clamping plate to avoid deflection during the up and down movement and affect the clamping and fixing effect. In addition, rubber pads are provided on the upper clamping plate and the lower clamping seat. The rubber pads can increase the friction between the pipe fittings and thereby improve the clamping and fixing effect.

[0014] In one possible implementation, a bracket is fixedly provided on the base plate near the pipe cutting machine, on which a rubber support plate is fixedly mounted, and the upper end surface of the rubber support plate is flush with the upper end surface of the rubber clamping pad on the lower clamping seat. The above-mentioned structural form can support the other end of the pipe fitting, so that the pipe fitting can remain in a horizontal state during the movement and cutting process, avoiding the occurrence of uneven cutting edges.

[0015] In summary, the present invention has the following beneficial technical effects:

[0016] Before cutting, the pipe end clamping limit frame is used to clamp and fix the end of the pipe to be cut to prevent the pipe from sliding or offsetting during cutting, and the pipe end clamping limit frame can slide along the sliding rod frame to adjust the cutting length. When it is necessary to cut a pipe of a specified length, the position of the limit baffle can be adjusted according to the reference plate, that is, the maximum travel point of the pipe end clamping limit frame, that is, the maximum cutting length of the pipe. When the pipe end clamping limit frame is slid to make it fit with the limit baffle, the pipe also moves to the cutting point of the specified length. At this time, the pipe of the specified length can be cut. The operation is simple and the cutting length is relatively accurate. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The technical solution in the embodiments of the present application is to solve the problems of the above-mentioned background technology, and the overall idea is as follows:

[0023] like Figure 1 As shown, the present embodiment provides a stainless steel pipe cutting device with a limiting function, comprising a base plate 1, wherein a sliding rod frame 2 and a pipe cutter 6 are fixedly provided at both ends of the upper end face thereof, the pipe cutter 6 is used to cut the pipe, the pipe end clamping limiting frame 5 is slidably arranged on the sliding rod frame 2, and is used to clamp and fix the end of the pipe to be cut to prevent the pipe from sliding or deflecting during cutting, and the pipe end clamping limiting frame 5 can slide along the sliding rod frame 2, thereby realizing the adjustment of the cutting length, and the limiting baffle 3 is slidably arranged on the sliding rod frame 2 On the top, and located in front of the pipe end clamping limit frame 5, it is used to limit the maximum stroke of the pipe end clamping limit frame 5, wherein a reference plate 4 is fixedly provided on the base plate 1, which serves as a reference for judging the current position of the limit baffle 3. When it is necessary to cut a pipe of a specified length, the position of the limit baffle 3 can be adjusted according to the reference plate 4, that is, the maximum cutting length of the pipe. When the pipe end clamping limit frame 5 is slid to make it fit with the limit baffle 3, the pipe also moves to the cutting point of the specified length, and the pipe of the specified length can be cut at this time.

[0024] like Figure 2 As shown, the sliding rod frame 2 includes two groups of symmetrically arranged end fixing plates 21, and a sliding rod 22 is fixedly connected between each group of end fixing plates 21. The sliding rod 22 provides the necessary structural basis for the sliding connection between the pipe end clamping limit frame 5 and the limit baffle 3, and the end fixing plate 21 can suspend the sliding rod 22 to ensure that it can perform its normal function.

[0025] like Figure 2As shown, the limit baffle 3 includes a sliding ring 31 that is slidably mounted on the slide rod 22. The sliding rings 31 are fixedly connected by a cross-connecting plate 32. The cross-connecting plate 32 can block the pipe end clamping limit frame 5 and limit its maximum stroke, while the sliding ring 31 is used to realize the sliding connection between the cross-connecting plate 32 and the slide rod 22.

[0026] Among them, in order to ensure that the position of the limit baffle 3 after adjustment cannot be easily changed, that is, to avoid changes in the cutting length, a locking groove 23 is provided on the sliding rod 22, and the locking groove 23 is arranged along the length direction of the sliding rod 22. At the same time, a bolt locking piece 33 is threadedly connected to the sliding ring 31, and when the bolt locking piece 33 is tightened, its bottom end is in close contact with the locking groove 23. When the position adjustment of the limit baffle 3 is completed, the bolt locking piece 33 is tightened. At this time, the position of the limit baffle 3 is fixed and cannot continue to slide, ensuring that it can play a reliable limiting role on the pipe end clamping limit frame 5, avoiding it from sliding after being hit by the pipe end clamping limit frame 5, resulting in changes in the maximum cutting length of the pipe fitting.

[0027] like Figure 2 As shown, a bending pointer 34 is fixedly connected to the side of the sliding ring 31, and a plurality of scale grooves 41 are opened on the reference plate 4. Corresponding scale lines are drawn in the grooves, and the tip of the bending pointer 34 points to the corresponding scale line. The corresponding scale line reading of the bending pointer 34 changes synchronously during the movement. The operator can judge the current position of the limit baffle 3 based on this, so that he can adjust the position of the limit baffle 3 more accurately, thereby ensuring the accuracy of the cutting length.

[0028] like Figure 3 As shown, the pipe end clamping limit frame 5 includes a lower clamping seat 51, and sliding sleeves 52 slidably mounted on the sliding rod 22 are fixedly connected on both sides of the lower clamping seat 51. A door frame 53 is fixedly arranged on the lower clamping seat 51, and an upper clamping plate 54 is slidably arranged in the door frame 53, and an adjusting threaded rod 55 is threadedly connected to the door frame 53. The bottom end of the adjusting threaded rod 55 is rotatably connected to the upper clamping plate 54. When the adjusting threaded rod 55 is screwed, it will drive the upper clamping plate 54 to move up and down, and then the clamping action of the upper clamping plate 54 and the lower clamping seat 51 is used to clamp and fix the end of the pipe fitting.

[0029] In addition, in order to make the pipe end clamping limit frame 5 easier to use and have a better clamping and limiting effect, an adjusting handwheel 56 is fixedly connected to the top of the adjusting threaded rod 55, which can facilitate the operator to rotate the adjusting threaded rod 55 by twisting it. A guide rod 57 is fixedly connected to the upper clamping plate 54. The guide rod 57 passes through the door frame 53 and slides in contact with it. The guide rod 57 can guide the movement of the upper clamping plate 54 to prevent it from deflecting during the up and down movement and affecting the clamping and fixing effect. In addition, rubber pads 58 are provided on the upper clamping plate 54 and the lower clamping seat 51. The rubber pads 58 can increase the friction between the pipe fittings and thereby improve the clamping and fixing effect.

[0030] like Figure 1 As shown, a bracket 11 is fixedly provided on the base plate 1 near the pipe cutting machine 6, on which a rubber support plate 12 is fixedly mounted, and the upper end surface of the rubber support plate 12 is flush with the upper end surface of the rubber clamping pad 58 on the lower clamping seat 51. The above-mentioned structural form can lift the other end of the pipe fitting, so that the pipe fitting can maintain a horizontal state during the movement and cutting process, avoiding the occurrence of uneven cutting edges.

[0031] The use principle and use process of this utility model:

[0032] Before cutting, the pipe end clamping limit frame 5 is used to clamp and fix the end of the pipe to be cut to prevent the pipe from sliding or shifting during cutting. Specifically, when the adjusting threaded rod 55 is turned, it will drive the upper clamping plate 54 to move up and down, and then the clamping action of the upper clamping plate 54 and the lower clamping seat 51 is used to clamp and fix the end of the pipe. In addition, rubber clamping pads 58 are provided on the upper clamping plate 54 and the lower clamping seat 51. The rubber clamping pads 58 can increase the friction between the pipe and the pipe, thereby improving the clamping and fixing effect.

[0033] Since the pipe end clamping limit frame 5 can slide along the sliding rod frame 2, the cutting length can be adjusted. When it is necessary to cut a pipe of a specified length, the position of the limit baffle 3 can be adjusted according to the reference plate 4, that is, the maximum stroke point of the pipe end clamping limit frame 5, that is, the maximum cutting length of the pipe. When the pipe end clamping limit frame 5 is slid to fit it with the limit baffle 3, the pipe also moves to the cutting point of the specified length. At this time, the pipe of the specified length can be cut. The operation is simple and the cutting length is more accurate.

[0034] In order to ensure that the position of the limit baffle 3 after adjustment cannot be easily changed, that is, to avoid changes in the cutting length, a locking groove 23 is provided on the sliding rod 22, and a bolt locking part 33 is threadedly connected to the sliding ring 31. When the position adjustment of the limit baffle 3 is completed, the bolt locking part 33 is tightened. At this time, the position of the limit baffle 3 is fixed and cannot continue to slide, ensuring that it can play a reliable limiting role on the pipe end clamping limit frame 5, avoiding it from sliding after being hit by the pipe end clamping limit frame 5, resulting in changes in the maximum cutting length of the pipe.

[0035] Finally, it should be noted that the above embodiments are merely examples for the purpose of illustrating the present invention and are not intended to limit the embodiments. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to provide an exhaustive list of all possible embodiments. However, any obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
