Description

Technical Field

[0001] The utility model relates to the field of hole opening processing, in particular to a hole opening processing device for rubber and plastic insulation pipes. Background Art

[0002] Rubber and plastic insulation materials are elastic closed-cell foaming materials, which have the advantages of low thermal conductivity, fire prevention and flame retardancy, moisture-proof and moisture-barrier, shock absorption and noise reduction, environmental protection and health, long service life, simple and elegant appearance, and convenient installation. They are widely used in heat and cold medium insulation and cold protection of central air conditioners, buildings, chemical industries, light textiles, metallurgy, automobiles, electrical appliances, etc.

[0003] Under the existing technology, a simple fixing structure is used to clamp rubber and plastic pipe fittings. Because of the single clamping and fixing from the outside to the inside, it is very easy to cause excessive extrusion of the soft-structured rubber and plastic insulation pipes, resulting in deformation of the rubber and plastic pipe fittings. In this way, it is difficult to accurately position the rubber and plastic insulation pipes, and because the orientation of hole opening processing is variable, it is difficult to adjust the position and state of the fixed rubber and plastic insulation pipes, so effective and accurate hole opening processing cannot be carried out on the pipe fittings. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problem that it is difficult to limit and fix rubber and plastic insulation pipes in the existing technology, and a hole opening processing device for rubber and plastic insulation pipes is proposed.

[0008] Preferably, the limiting mechanism includes a fixed pile integrally connected to the machine body, and a clamping rod movably pulled by the driving cylinder is pin-mounted on the fixed pile. A limiting chute is opened in the machine body, and a strong spring fixedly connected and a guiding slider movably pulled by the clamping rod are arranged in the limiting chute. A fixed clamping plate for fixedly clamping the left end part of the insulation pipe fitting is integrally arranged on the guiding slider;

[0009] The limiting mechanism further includes a telescopic device fixedly connected to the output end of the driving motor, and a shaping sleeve for supporting and fixing the right end of the insulation pipe fitting is fixedly connected to the output end of the telescopic device.

[0010] Preferably, a first connecting rod is pin-connected between the output end of the driving cylinder and the opening and closing rod.

[0011] Preferably, the strong spring is fixedly installed at one end of the limiting sliding groove, and the guiding slider is slidably sleeved in the limiting sliding groove. A through hole for slidably sleeving the opening and closing rod is formed in the guiding slider.

[0012] Preferably, a heightening platform is integrally connected to the machine body, and a hollow bracket for fixedly sleeving the telescopic device is rotatably installed on the heightening platform.

[0013] Compared with the prior art, the present utility model has the following advantages:

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0021] Reference Figures 1-3 , a rubber and plastic insulation pipe hole-opening processing device, including a machine body 1 and a drill support plate 2. A driving cylinder 5 and a driving motor 17 are respectively fixedly installed at the left and right ends of the machine body 1. A limiting mechanism for fixing and adjusting the insulation pipe fittings is arranged on the machine body 1 through the driving cylinder 5 and the driving motor 17.

[0022] Specifically refer to the attached drawings of the specification Figure 1 and the attached Figure 2 , the limiting mechanism includes a fixed pile 6 integrally connected to the machine body 1, and a clamping rod 9 driven by the driving cylinder 5 is pin-installed on the fixed pile 6. A first connecting rod 8 is pin-connected between the output end of the driving cylinder 5 and the clamping rod 9. The clamping rod 9 is pulled by the first connecting rod 8. A limiting chute 11 is opened in the machine body 1. A strong spring 10 fixedly connected and a guiding slider 12 driven by the clamping rod 9 are arranged in the limiting chute 11. A fixed clamping plate 7 for fixedly clamping the left end part of the insulation pipe fitting is integrally arranged on the guiding slider 12. In addition, the strong spring 10 is fixedly installed in one end of the limiting chute 11, and the guiding slider 12 is slidably sleeved in the limiting chute 11. The strong spring 10 can provide elastic support for the guiding slider 12 linearly moving in the limiting chute 11. A through hole for slidably sleeving the clamping rod 9 is opened in the guiding slider 12. Due to the pulling of the first connecting rod 8, the clamping rod 9 deflects with the fixed pile 6 as the center of the circle. While deflecting in the through hole, the deflecting clamping rod 9 expands and contracts, thereby driving the guiding slider 12 to linearly reciprocate.

[0023] An elevation platform 13 is integrally connected to the machine body 1. The increase in height makes the processing of the insulation pipe fitting more convenient, and at the same time gives space for the rotation track of the expander 16. A hollow bracket 15 for fixedly sleeving the expander 16 is rotatably installed on the elevation platform 13. On the elevation platform 13, the expander 16 fixedly connected to the output end of the driving motor 17, and a shaping sleeve 14 for supporting and fixing the right end of the insulation pipe fitting is fixedly connected to the output end of the expander 16. The shaping sleeve 14 enters the insulation pipe fitting through the right end of the insulation pipe fitting to support the insulation pipe fitting from the inside to the outside, avoiding the structural deformation caused by the insulation pipe fitting being clamped and flattened.

[0024] It should be noted that the specific model specifications of the motor, cylinder and expander 16 need to be selected according to the actual specifications of the device, etc. The specific selection calculation method adopts the existing technology in the field, so it will not be elaborated.

[0025] The function principle of the present utility model can be described by the following operation method:

[0026] The rubber-plastic insulation pipe is installed horizontally through the fixed clamping plate 7 and the shaping sleeve 14, and the driving cylinder 5 is turned on to control the first connecting rod 8 to push forward and backward, thereby driving the opening and closing rod 9 to deflect with the fixed pile 6 as the fulcrum, and then driving the guide slider 12 to slide in the limiting slide groove 11, and making the strong spring 10 expand and contract synchronously, thereby driving the fixed clamping plate 7 connected to the guide slider 12 to move toward each other, so as to achieve the limiting and fixing effect on the insulation pipe fittings;

[0027] By opening the expansion joint 16, the shaping sleeve 14 is passed through the rubber-plastic insulation pipe to the position of the fixed clamp 7. The fixed clamp 7 interacts with the shaping sleeve 14 to make the rubber-plastic insulation pipe more stable. By opening the driving motor 17, the expansion joint 16 generates a rotational motion, thereby driving the insulation pipe to flip and adjust to the required opening angle.

[0028] The elevator 3 is controlled to open, driving the hole opener 4 to perform fixed-point hole opening on the thermal insulation pipe fittings at fixed positions.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
