Description

Technical Field

[0001] The utility model relates to the technical field of thermal insulation pipe processing, in particular to a cutting device with a distance-fixing function. Background Art

[0002] Insulated pipe is the abbreviation of insulated pipe. Insulated pipe is used for the transportation of liquid, gas and other media. It is used for thermal insulation of pipelines in petroleum, chemical, aerospace, hot spring, military, central heating, central air conditioning, municipal and other fields. Existing insulated pipes need to be cut during production.

[0003] For example, the publication number CN217434453U discloses a fixed-distance cutting device for TPU tube production and processing. The device is provided with two sets of slide grooves on the discharge plate, and a mounting frame is slidably installed on the slide groove, and a positioning plate is fixedly installed on the mounting frame. The positioning plate is used to cut the tube at a fixed distance.

[0004] However, the practicality of the positioning structure is poor when in use. When adjusting the position of the positioning plate, the positioning member structure directly slides the mounting frame on the surface of the slide groove to complete the adjustment of the position of the positioning plate, but there is no fixed structure for the mounting frame or the positioning plate. This makes it easy for the pipeline to move directly backward after contact with the positioning plate and cannot be automatically limited, thereby reducing the practicality of the device. In view of this, we propose a cutting device with a distance-fixing function. Utility Model Content

[0005] The purpose of the utility model is to provide a cutting device with a distance-fixing function to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above object, the utility model provides the following technical solution: a cutting device with a distance-fixing function, comprising a support frame, a U-shaped frame is fixedly installed on the upper end of the support frame, a cutting structure is arranged inside the U-shaped frame, a feeding plate is fixedly installed on the upper end of the support frame, a positioning structure is arranged inside the feeding plate, and the positioning structure comprises:

[0007] A notch is provided inside the loading plate, a screw is rotatably connected to the inner wall of the notch through a sleeve, a sleeve is threadedly connected to the surface of the screw, a connecting block is fixedly installed on the upper end of the sleeve, and the upper end of the connecting block passes through the side wall of the loading plate and is fixedly connected to the lower end of the positioning plate;

[0008] A rotating rod, one end of which is fixedly connected to the end of the screw rod, and the other end of which passes through the side wall of the loading plate and is fixedly mounted with a handle, and a supporting structure is arranged inside the loading plate.

[0009] Preferably, the supporting structure includes a bayonet opened on the side wall of the positioning plate, a fixing plate is fixedly installed on the inner wall of the bayonet, a moving rod passes through the side wall of the fixing plate, a pressure plate is fixedly installed on one end of the moving rod, a connecting plate is fixedly installed on the other end of the moving rod, and a return spring is arranged on the surface of the moving rod.

[0010] Preferably, a positioning tube passes through the inner wall of the positioning plate, and a sliding rod is slidably connected to the inner wall of the positioning tube, a connecting strip is fixedly installed on one end of the sliding rod, and a support plate is fixedly installed on the other end of the sliding rod, the lower end of the connecting strip is fixedly connected to the upper end of the connecting plate, and a sliding block is slidably connected to the side wall of the positioning plate, a support plate is fixedly installed on the lower end of the sliding block, one end of the connecting rod is hinged to the upper end of the sliding block, and the other end of the connecting rod is hinged to the lower end of the support plate.

[0011] Preferably, the lower end of the support plate is arranged as an arc-shaped structure and a rubber pad is fixedly mounted on the surface, so that the rubber pad can play a certain buffering and protective role when supporting the surface of the pipe fitting.

[0012] Preferably, one end of the return spring is fixedly connected to the side wall of the pressure plate, and the other end of the return spring is fixedly connected to the side wall of the fixed plate.

[0013] Preferably, a sliding opening adapted to the moving track of the connecting block is provided on the upper end of the loading plate, so that the connecting block can be easily moved.

[0014] Compared with the prior art, the utility model provides a cutting device with a distance-fixing function, which has the following beneficial effects:

[0015] 1. The cutting device with a fixed distance function is provided with a positioning structure so that pipes of different lengths can be cut at fixed distances by adjusting the positioning plate. The user can drive the sleeve on its surface to move by rotating the screw, and the connection block and the positioning plate at its upper end can be driven to move left and right by the movement of the sleeve. The connection block and the positioning plate can be supported and fixed by the self-locking property of the screw, so as to avoid the pipe being easily driven to move backward directly after contacting the positioning plate and being unable to limit automatically.

[0016] 2. The cutting equipment with the distance-fixing function is conveniently supported and fixed on the upper end of the pipe after the distance-fixing is completed by setting a supporting structure. When the pipe moves toward the positioning plate, the pressure plate of the pipe contacts and drives it to move. At this time, the movement of the connecting plate drives the connecting bar to move, and the movement of the connecting bar drives the support plate to move. The movement of the support plate drives the slider and the support plate to move downward to support and fix the upper end of the pipe, thereby avoiding shaking of the pipe during cutting and affecting its use.
