Description

Technical Field

[0001] The utility model relates to the field of PE pipe processing, in particular to a large-diameter PE pipe cutting component. Background Art

[0002] PE pipes are usually long when they are fed, and they generally need to be cut into the required length according to actual needs during use. Among them, large-diameter PE pipes often need to be cut using a large cutting machine. This large cutting machine is not only expensive, but more importantly, it is not easy to carry. Therefore, when many construction sites need to cut PE pipes for construction, they can only carry a small cutting machine for cutting. However, it is difficult for this small cutting machine to complete the one-time cutting of large-diameter PE pipes, especially when the diameter of the PE pipe is larger than the diameter of the cutting knife. Therefore, in actual cutting, after the cutting machine cuts part of the PE pipe, the worker needs to turn the PE pipe to cut other parts, and this large-diameter PE pipe is very heavy. Therefore, the whole process is very difficult to operate manually, and it is difficult to ensure the stability of the square pipe during cutting, and the smoothness of the cut surface after the PE pipe is cut is even more difficult to ensure. Utility Model Content

[0003] In view of this, the purpose of the utility model is to propose a large-diameter PE pipe cutting assembly to solve the technical problems in the prior art that when a small and portable cutting machine is used to cut large-diameter PE pipes at a construction site, the operation is difficult and the stability of the PE pipe cannot be guaranteed during cutting.

[0004] Based on the above purpose, the utility model provides a large-diameter PE pipe cutting assembly, including a base arranged at the bottom and a cutting machine located above the base, the upper surface of the base is provided with a cutting area for placing the PE pipe, the cutting machine is used to cut the PE pipe placed in the cutting area, and limiting mechanisms are provided on both sides of the cutting area;

[0005] The limiting mechanism includes a lower clamping plate slidably connected to the base and an upper clamping plate connected above the lower clamping plate. Semicircular arc grooves of the same size are opened on opposite sides of the lower clamping plate. Several rolling parts are rotatably connected in the semicircular arc grooves of the upper clamping plate above the lower clamping plate to reduce the resistance encountered by the PE pipe when rotating in the cutting area by rolling friction instead of sliding friction.

[0006] Furthermore, two fasteners are symmetrically arranged on the upper clamping plate and the lower clamping plate, the upper half of the fastener is a round rod and is rotatably connected in the upper clamping plate, and the lower half of the fastener is a screw and is threadedly connected in the lower clamping plate.

[0007] Furthermore, a screw hole for threaded connection of the screw rod portion of the fastener is provided in the lower clamping plate, and a limiting groove is provided below the screw hole. The lower end of the fastener is fixedly connected to a limiting rod, and the limiting rod is movably connected in the limiting groove.

[0008] Furthermore, the rolling element can be configured as a roller whose axial direction is the same as that of the semicircular arc groove, or can be configured as a ball.

[0009] Furthermore, the cutting machine is rotatably connected to the base via a rotating bracket, the lower end of the rotating bracket is fixedly connected to the middle position of the upper end surface of the base, and the cutting machine is rotatably connected to the upper end of the rotating bracket.

[0021] Specific implementation method and principle

[0022] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0023] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the present invention should be understood by people with ordinary skills in the field to which the present invention belongs.

When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0024] The first aspect of the utility model is as follows Figure 1 and Figure 2 As shown, in this scheme, a base 101 is arranged at the bottom, and a cutting machine 103 and a limiting mechanism are arranged above the base 101, wherein the cutting machine 103 is rotatably connected to the base 101 through a rotating bracket 102, the lower end of the rotating bracket 102 is fixedly connected to the middle position of the upper end surface of the base 101, and the cutting machine 103 is rotatably connected to the upper end of the rotating bracket 102.

[0025] A cutting area for placing the PE pipe 01 is provided on the upper surface of the base 101 (located in the middle of the upper surface of the base 101 in front of the cutting machine 103). The cutting machine 103 is used to cut the PE pipe 01 placed in the cutting area, and two groups of limiting mechanisms are provided, which are respectively located on the left and right sides of the cutting area.

[0026] Specifically, Figure 4 As shown, the limiting mechanism consists of two major parts: a lower clamping plate 104 slidably connected to the base 101 and an upper clamping plate 105 connected above the lower clamping plate 104. Semi-circular grooves of the same size are opened on the opposite sides of the lower clamping plate 104 and the upper clamping plate 105. This semi-circular groove is used to support and position the PE pipe 01.

[0027] Two fasteners 106 are symmetrically arranged on the upper clamping plate 105 and the lower clamping plate 104. The upper half of the fastener 106 is a round rod and is rotatably connected in the upper clamping plate 105, and the lower half of the fastener 106 is a screw and is threadedly connected in the lower clamping plate 104. A screw hole 112 for the screw part of the fastener 106 to be threadedly connected is arranged in the lower clamping plate 104, and a limiting groove 113 is also arranged below the screw hole 112. The lower end of the fastener 106 is fixedly connected to a limiting rod 111, and the limiting rod 111 is movably connected in the limiting groove 113.

[0028] By rotating the fastener 106, the screw rod in the lower part of the fastener 106 rotates in the screw hole 112 in the lower clamping plate 104, thereby adjusting the distance between the upper clamping plate 105 and the lower clamping plate 104. In this way, the upper clamping plate 105 and the lower clamping plate 104 can clamp PE pipes 01 of various calibers within a certain range.

[0029] The fastener 106 is passed through the upper clamping plate 105 , and a handle is provided at the upper end of the fastener 106 for facilitating the worker to rotate it.

[0030] Preferably, a plurality of rolling elements 107 are rotatably connected in the semicircular groove of the upper clamping plate 105 above the lower clamping plate 104, so as to reduce the resistance of the PE tube 01 when rotating in the cutting area by rolling friction instead of sliding friction. Among them, the rolling element 107 can be set as a roller with the same axial direction as the semicircular groove, or can be set as a ball. The disadvantage of setting it as a ball is that the rotation direction of the ball is not restricted, so the PE tube 01 clamped by the lower clamping plate 104 and the upper clamping plate 105 is also prone to move in the left and right direction (the axial direction of the semicircular groove), so that when cutting, the PE tube 01 may shake in direction, resulting in poor stability.

[0031] This problem will not occur if the roller is set, because the axial direction is the same as the axial direction of the semicircular groove, so the roller will only rotate along the circumferential direction of the semicircular groove. That is, it only promotes the rotation of the PE pipe 01 clamped by the lower clamping plate 104 and the upper clamping plate 105, and cannot shake in the front, back, left, right, up and down directions, ensuring the stability during cutting.

[0032] On the other hand, Figure 3 and Figure 4As shown, although the cutting machine 103 is rotatably connected to the base 101 through the rotating bracket 102, since the lower end of the rotating bracket 102 is fixedly connected to the middle position of the upper end surface of the base 101, the cutting machine 103 can only move in a small range in the middle position of the upper end surface of the base 101. Therefore, in order to adapt to PE pipes 01 of various diameters, the limit machine is also set to be movable.

[0033] The specific method is that a sliding bottom plate 109 is fixedly connected to the bottom of the lower clamping plate 104, and a sliding groove 108 is provided on the base 101 in the length direction of the lower clamping plate 104, and the sliding bottom plate 109 is slidably connected in the sliding groove 108. Among them, one end of the sliding bottom plate 109 has a protruding part, and the fixing bolt 110 is set in this part. The protruding sliding bottom plate 109 is provided with a hole that passes through from top to bottom, and the fixing bolt 110 is threadedly connected in the hole. When the lower clamping plate 104 and the sliding bottom plate 109 need to be fixed, the fixing bolt 110 is tightened to make it press against the bottom of the sliding groove 108, thereby achieving fixation. DETAILED DESCRIPTION

[0034] Before cutting the large-diameter PE pipe 01, first place the base 101, preferably on flat ground, to ensure the stability of the equipment during cutting. Then, by rotating the fastener 106, the screw rod of the lower part of the fastener 106 rotates in the screw hole 112 in the lower clamping plate 104, and then the distance between the upper clamping plate 105 and the lower clamping plate 104 is adjusted, so that the large-diameter PE pipe 01 can pass smoothly between the upper clamping plate 105 and the lower clamping plate 104.

[0035] After the above preparations are completed, the large-diameter PE pipe 01 is passed between the upper clamping plate 105 and the lower clamping plate 104 in the two sets of limiting mechanisms, and placed in the semicircular arc groove on the lower clamping plate 104, and then the fastener 106 is rotated again to adjust the distance between the upper clamping plate 105 and the lower clamping plate 104, so that the upper clamping plate 105 and the lower clamping plate 104 clamp the PE pipe 01.

[0036] Then adjust the position of the limit mechanism, first loosen the fixing bolt 110, slide along the slide groove 108 through the sliding bottom plate 109, so that the entire limit mechanism and the PE pipe 01 move to a position suitable for cutting by the cutting machine 103. Then tighten the fixing bolt 110 to make it against the bottom of the slide groove 108, thereby fixing the limit mechanism and the PE pipe 01.

[0037] Finally, the worker manipulates the cutting machine 103 to start cutting, while another worker continuously rotates the PE tube 01. Since the semi-circular grooves of the lower clamping plate 104 and the upper clamping plate 105 are each connected to a plurality of rolling members 107, and the rolling members 107 are configured as rollers with the same axial direction as the semi-circular groove, the rollers can only rotate along the circumferential direction of the semi-circular groove. Therefore, when the PE tube 01 is rotated, it cannot shake in the front, back, left, right, up, and down directions, ensuring stability during cutting. The rolling members 107 replace the sliding friction between the PE tube 01 and the lower clamping plate 104 and the upper clamping plate 105 with rolling friction, so that the PE tube 01 can be easily rotated. The PE tube 01 is cut and rotated at the same time, realizing the small cutting machine to cut the large-diameter PE tube, and the PE tube can only rotate and cannot move in the front, back, left, right, up, and down directions, ensuring stability during cutting.

[0038] Based on the above, the utility model positions the PE tube 01 by setting a limit mechanism on both sides of the cutting area, so that the PE tube 01 can only rotate and cannot move in the front, back, left, right, up and down directions, thereby ensuring stability during cutting. A rolling member 107 is set in the limit mechanism to reduce the resistance of the PE tube 01 when it rotates in the cutting area by rolling friction instead of sliding friction, which not only reduces the difficulty of operation for workers, but also makes the PE tube rotate more smoothly and stably. The distance between the lower clamping plate 104 and the upper clamping plate 105 can be adjusted, and the limit mechanism itself can also move, so it can adapt to PE tubes 01 of various calibers within a certain range.

Under the concept of the present invention, the technical features in the above embodiments or different embodiments may be combined, the steps may be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in detail for the sake of simplicity.
