Description

Technical Field

[0001] The utility model relates to the technical field of pipe making machines, in particular to a gantry type extrusion forming pipe making machine. Background Technique

[0002] The gantry type extrusion forming pipe making machine occupies an important position in the pipe manufacturing industry due to its high efficiency. The extrusion pipe making machine is a processing device used to manufacture concrete pipe fittings. By rotating and extruding the inside of the concrete pipe fittings, the inner diameter size of the concrete pipe fittings can meet the requirements. After the material cools, solidifies and forms, it is poured out of the mold cylinder for curing.

[0003] When the existing extrusion pipe making machine feeds materials, it is usually directly poured from above the mold cylinder. However, this feeding method is uneven and easy to spill, and after pouring is completed, waste materials are likely to accumulate under the mold cylinder, affecting the stability when the mold cylinder is placed for the next pouring;

[0004] The existing patent (publication number: CN214491034U) discloses a radial extrusion pipe making machine, which includes a pipe making machine main body, a fixing plate fixedly connected to the right surface of the pipe making machine main body, and an extrusion rotating assembly installed inside the fixing plate. A feeding device is installed on the lower surface of the fixing plate, the outer surface of the feeding device is connected with a mold cylinder, and a fixing device is installed on the lower surface of the mold cylinder. By installing the feeding device, concrete can be evenly poured into the inside of the mold cylinder. And due to the shape characteristics of the corrugated pipe, when the extrusion rotating assembly rises and falls inside the mold cylinder, it will not affect the continuous feeding of the corrugated pipe. By installing the fixing device, when pouring concrete, the concrete falling to the bottom of the mold cylinder will be collected by the fixing seat, and the outer surface of the fixing cylinder is clamped inside the card slot. When the extrusion rotating assembly rotates and extrudes, the mold cylinder can be more stable.

[0005] In view of the above problems, although the solution given by the existing patent has the mold cylinder being more stable when the extrusion rotating assembly rotates and extrudes, it is not convenient to replace the pipe fitting mold. When processing pipe fitting molds with different diameters, it is necessary to replace the pipe making machine, which is rather troublesome. Summary of the Invention

Specific embodiments

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0026] The present utility model provides a technical solution:

[0027] Please refer to Figures 1 to 4 , a gantry type extrusion molding pipe making machine, including a mounting frame 1, a fixing frame 2 is fixed on the upper surface of the mounting frame 1, and an extrusion mechanism for forming raw materials is installed on the upper surface of the fixing frame 2;

[0028] The extrusion mechanism includes a driving motor 3, which is fixed to the upper surface of the fixed frame 2 by bolts. The power output shaft of the driving motor 3 penetrates through the fixed frame 2 and is fixed with a threaded pipe 31. A lead screw 32 is threadedly connected inside the threaded pipe 31. A protective shell 33 fixed to the fixed frame 2 is provided outside the threaded pipe 31. A connecting piece 34 is fixed to the lower end of the lead screw 32. A clamping groove 36 is formed inside the connecting piece 34. A clamping block 37 is clamped and connected inside the clamping groove 36. An extrusion piece 35 is fixed to the lower end of the clamping block 37. A fixing bolt 38 is installed on the outer wall of the connecting piece 34, and the end of the fixing bolt 38 abuts against the outer surface of the clamping block 37. A driving motor 39 is fixed to the upper end inside the extrusion piece 35 by bolts. An auxiliary piece 310 is fixed to the power output shaft of the driving motor 39. A slider 311 slidably connected to the extrusion piece 35 is fixed to the upper surface of the auxiliary piece 310. A rotating structure is formed between the auxiliary piece 310 and the driving motor 39.

[0029] By adopting the above technical solution, before using the gantry type extrusion molding pipe making machine, the mounting frame 1 is first placed in a suitable position. During use, the raw material is poured into the molding cylinder 4. The driving motor 3 arranged on the fixed frame 2 can drive the threaded pipe 31 to rotate, thereby driving the vertically moving lead screw 32 connected by threads to drive the connecting piece 34 to move. And two guide rods are telescopically connected to the lower end of the protective shell 33, and the lower ends of the guide rods are fixed to the connecting piece 34, thereby guiding the connecting piece 34. The extrusion piece 35 is driven to move into the molding cylinder 4 to extrude and form the raw material. At the same time, the driving motor 39 arranged inside the extrusion piece 35 is started to drive the auxiliary piece 310 to rotate. With the cooperation of the slider 311, the rotation of the auxiliary piece 310 is made smoother, thereby smoothing the inner wall of the extruded raw material and improving the practicability. By unscrewing the fixing bolt 38 on the connecting piece 34, the fixing of the clamping block 37 can be released. With the cooperation of the clamping groove 36, the extrusion piece 35 can be disassembled, thereby facilitating the replacement of the extrusion piece 35 with different diameters and facilitating the processing of workpieces with different diameters, improving the practicability.

[0030] Specifically, as Figures 1 - 4 shown, a molding cylinder 4 is installed inside the mounting frame 1. Fixing plates 5 are fixed to both ends of the inner wall of the mounting frame 1. A clamping electric cylinder 6 is fixed to the side wall of the fixing plate 5 by bolts. The telescopic end of the clamping electric cylinder 6 penetrates through the fixing plate 5 and is fixed with a clamping plate 7. An anti-slip gasket 8 is adhered to the side wall of the clamping plate 7.

[0031] By adopting the above technical solution, the molding cylinder 4 is placed inside the mounting frame 1. Through the two clamping electric cylinders 6 arranged on the fixing plate 5, the two clamping plates 7 can be driven to move relatively, thereby clamping the molding cylinder 4, which can effectively reduce the displacement of the molding cylinder 4, and the anti-slip gasket 8 provided can play an anti-slip role.

[0032] Working principle: Place the forming cylinder 4 inside the mounting frame 1. Through the two clamping electric cylinders 6 arranged on the fixing plate 5, drive the two clamping plates 7 to move relatively to clamp the forming cylinder 4. The anti-slip gasket 8 can play an anti-slip role. Pour the raw material into the forming cylinder 4. The drive motor 3 arranged on the fixing frame 2 drives the threaded pipe 31 to rotate, and then drives the vertically moving screw rod 32 connected by threads to drive the connecting piece 34 to move. And two guide rods are telescopically connected to the lower end of the protective shell 33, and the lower ends of the guide rods are fixed to the connecting piece 34, so as to guide the connecting piece 34. The extrusion part 35 is driven to move into the forming cylinder 4 to extrude and form the raw material. The drive motor 39 drives the auxiliary part 310 to rotate. With the cooperation of the slider 311, the rotation of the auxiliary part 310 is smoother, and then the inner wall of the extruded raw material is smoothed. By unscrewing the fixing bolt 38 on the connecting piece 34, the fixing of the clamping block 37 can be released. With the cooperation of the clamping groove 36, the extrusion part 35 can be disassembled, which is convenient for replacing the extrusion parts 35 with different diameters and is convenient for processing workpieces with different diameters.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
