Description

Technical Field

[0001] The utility model relates to a shaping device, in particular to an end shaping device of a polymer prefabricated irrigation channel. Background Art

[0002] Ditches are an important part of farmland water conservancy. In order to ensure long-term use of ditches and avoid water erosion, cement prefabricated ditches are generally laid on the surface of the excavated earth ditches. Since cement prefabricated ditches are made of cement, they are relatively heavy and inconvenient for construction and installation. Cement is not resistant to acid corrosion and is easily corroded in the acidic environment of soil and water. The patent application with announcement number CN220468792U discloses a prefabricated irrigation canal made of polymer materials, which is formed by co-extrusion of polymer materials and is resistant to aging and corrosion; and because it is a polymer product, it is light in weight and easy to install.

[0003] The production process of polymer prefabricated irrigation channels includes extrusion, cooling molding, punching, cutting, and end shaping. The purpose of the end shaping is to make the inner wall of one end of the polymer prefabricated irrigation channel concave through shaping, so that when the polymer prefabricated irrigation channels are overlapped, the inner wall between the polymer prefabricated irrigation channels can have a smooth transition.

[0004] The patent application with announcement number CN217451841U discloses an expansion mold for special-shaped pipe fittings, which includes a high-pressure air intake pipe, one end of which is connected to an end assembly, and the other end of the end assembly is connected to an intermediate assembly, the intermediate assembly includes a flexible intermediate positioning sleeve, and the coaxial position of the intermediate positioning sleeve is respectively provided with a limit end plate and an intermediate expansion plate on both sides, the end of the intermediate expansion plate is connected to a positioning end head, the circular section of the positioning end head is provided with a positioning through hole, and a connecting middle cylinder is embedded in the middle of the end face of the positioning end head, and the connecting middle cylinder is connected to a connecting middle axis at the central axis position of the intermediate positioning sleeve and the intermediate expansion plate, and air pipe assemblies are symmetrically arranged on both sides of the connecting middle axis, and a supporting air bag is arranged in the inner cavity of the intermediate expansion plate, and the intermediate assembly and the end assembly are connected by the air pipe assembly, and an assembled structure is adopted, so that expansion operations can be carried out in different areas, and expansion operations on special-shaped pipes are realized, which solves the problem that traditional expansion equipment cannot expand special-shaped pipes.

[0005] Although the above expansion mold can expand the end of the plastic product, it is shaped by expanding the tube. Since the polymer prefabricated irrigation channel is not a closed form like a pipe, the above expansion mold cannot be used for the shaping of the polymer prefabricated irrigation channel. Therefore, it is necessary to design an end shaping device for the polymer prefabricated irrigation channel. Summary of the invention

[0006] The utility model aims to provide an end shaping device of a polymer prefabricated irrigation channel which can shape the end of a polymer prefabricated irrigation channel and ensure the shaping effect.

[0007] The technical solution of the utility model is:

[0009] The shaping mechanism is composed of a support frame, an upper lifting cylinder, an upper mold, a lower lifting cylinder and a lower mold. The support frame is in an inverted U shape. The upper mold is installed on the support frame through a symmetrically arranged upper lifting cylinder. The lower mold is installed on the frame below the upper mold through the lower lifting cylinder. The two sides of the upper mold and the two ends of the lower mold are slidably connected to the support frame through slide rails.

DETAILED DESCRIPTION

[0026] The end shaping device of the polymer prefabricated irrigation channel is composed of a conveying roller frame 1, a frame 2, a heating mechanism and a shaping mechanism. The frame 2 is arranged beside the end of the conveying roller frame 1, and the frame 2 is provided with a heating mechanism to heat the end of the polymer prefabricated ditch through the heating mechanism, and soften the end of the polymer prefabricated ditch by heating, thereby reducing the pressure required for shaping the polymer prefabricated ditch, and facilitating the shaping of the end of the polymer prefabricated ditch after cooling and hardening. The frame 2 between the heating mechanism and the conveying roller frame 1 is provided with a shaping mechanism to pressurize the end of the polymer prefabricated ditch through the shaping mechanism, and the end of the polymer prefabricated ditch is squeezed and deformed under the action of pressure, thereby shaping the end of the polymer prefabricated ditch. The conveying roller frame 1 includes a support frame, a drive motor and a conveying roller, and the drive motor can drive the conveying roller to rotate on the support frame. The function of the conveying roller frame 1 is to convey the polymer prefabricated groove through the conveying roller frame 1, and convey the polymer prefabricated groove through the shaping mechanism to the heating mechanism, so as to heat the end of the polymer prefabricated groove; after the end of the polymer prefabricated groove is heated, the polymer prefabricated groove is returned to the shaping mechanism, so as to shape the end of the polymer prefabricated groove.

[0027] The shaping mechanism is composed of a support frame 3, an upper lifting cylinder 4, an upper die 5, a lower lifting cylinder 6 and a lower die 7. The support frame 3 is in an inverted U shape. The upper lifting cylinder 4 is symmetrically arranged on the support frame 3. The piston rod end of the upper lifting cylinder 4 extends between the support frames 3. The piston rod end of the upper lifting cylinder 4 extending between the support frames 3 is installed with an upper die 5. Both sides of the upper die 5 are slidably connected to the support frame 3 through slide rails. The function of the upper lifting cylinder 4 is to drive the upper die 5 to rise and fall through the upper lifting cylinder 4, so as to squeeze the polymer prefabricated ditch downward during the downward process of the upper die 5. The lower die 7 is installed on the frame 1 below the upper die 5 through the lower lifting cylinder 6, and the two ends of the lower die 7 are slidably connected to the support frame 3 through slide rails. The function of the lower lifting cylinder 6 is to drive the lower mold 7 to move up and down through the lower lifting cylinder 6, thereby driving the lower mold 7 to extrude the end of the polymer prefabricated groove upward, thereby clamping and squeezing the end of the polymer prefabricated groove through the upward moving lower mold 7 and the downward moving upper mold 5, so as to shape the end of the polymer prefabricated groove.

[0028] The upper mold 5 is in the shape of an inverted "concave" character, and the lower mold 7 is in the shape of a "convex" character, so that the upper mold 5 and the lower mold 7 adapt to the shape of the polymer prefabricated trench, thereby keeping the overall shape of the end of the polymer prefabricated trench unchanged.

[0029] The upper die 5 and the lower die 7 are respectively stacked by a plurality of iron plates, and the stacked iron plates are fixedly connected by bolts. Since the upper die 5 and the lower die 7 are respectively stacked by a plurality of iron plates, the structures of the upper die 5 and the lower die 7 can be easily adjusted, and when the upper die 5 and the lower die 7 are worn, only the worn iron plates need to be replaced, thereby effectively reducing the maintenance cost of the upper die 5 and the lower die 7.

[0030] The upper mold 5 is provided with a positioning shoulder 8 to position the rear of the end of the polymer prefabricated groove through the positioning shoulder 8 so that only the end of the polymer prefabricated groove is squeezed to deform it.

[0031] Guide rods 9 are respectively provided on the lower mold 7 on both sides of the lower lifting cylinder 6, and the guide rods 9 are movably plug-connected with the frame 2. The function of the guide rods 9 is to guide the lifting of the lower mold 7 through the guide rods 9 to prevent the lower mold 7 from deflecting during the movement, thereby ensuring the shaping effect; on the other hand, to prevent the piston rod of the lower lifting cylinder 6 from deflecting during the movement, and to protect the seal of the lower lifting cylinder 6.

[0032] The heating mechanism is composed of a heat insulation box 10 and a heating resistor 11. A socket 12 is provided on the heat insulation box 10 on one side of the shaping mechanism. The heating resistors 11 are evenly distributed in the heat insulation box 10 on the upper and lower sides of the socket 12, so that heat is generated by the heating resistors 11 after power is turned on, thereby heating the polymer prefabricated ditch. Since the heating resistors 11 are evenly distributed on the upper and lower sides of the socket 12, they can heat the upper and lower sides of the end of the polymer prefabricated ditch simultaneously, quickly and evenly, thereby improving the heating efficiency. The function of the heat insulation box 10 is to insulate the heat through the heat insulation box 10 to avoid burns and effectively avoid safety accidents; on the other hand, the heat is not easily dissipated outward by isolating the heat through the heat insulation box 10, so that the heat acts on the polymer prefabricated ditch as much as possible, thereby effectively reducing energy consumption.

[0033] Guide rollers 13 are evenly distributed on both sides of the conveying roller frame 1, so as to guide the polymer prefabricated groove through the guide rollers 13, so as to guide the polymer prefabricated groove to be inserted between the upper mold 5 and the lower mold 7 of the shaping mechanism.

[0034] When the end shaping device of the polymer prefabricated irrigation channel is working, the heating resistance wire 11 of the heating mechanism is energized to preheat the interior of the isolation box 10. After the interior of the isolation box 10 is preheated, the polymer prefabricated irrigation channel is hoisted onto the conveying roller frame 1 so that it is between the guide rollers 13 along the conveying roller frame 1. After the polymer prefabricated irrigation channel is hoisted into place, the conveying roller frame 1 is started, and the end of the polymer prefabricated irrigation channel is passed through the lower mold 7 and the upper mold 5 of the shaping mechanism and the socket 12 of the isolation box 10 and inserted into the heating resistance wire 11. After the polymer prefabricated irrigation channel moves into place, the end of the polymer prefabricated irrigation channel is heated by the energized heating resistance wire 11, so that the temperature of the end of the polymer prefabricated irrigation channel is increased to 85-125 degrees Celsius, and the end of the polymer prefabricated irrigation channel is softened. After the heating of the end of the polymer prefabricated irrigation channel is completed, the conveying roller frame 1 is started to retract the end of the polymer prefabricated irrigation channel to between the upper mold 5 and the lower mold 7 of the shaping mechanism. After the polymer prefabricated irrigation channel moves to the right position, the upper lifting cylinder 4 and the lower lifting cylinder 6 are respectively started to drive the upper die 5 and the lower die 7 to squeeze the end of the polymer prefabricated irrigation channel respectively, and the end of the polymer prefabricated irrigation channel is squeezed and deformed by the upper die 5 and the lower die 7 to shape the end of the polymer prefabricated irrigation channel. During the shaping process of the polymer prefabricated irrigation channel, the upper die 5 and the lower die 7 dissipate heat from the end of the polymer prefabricated irrigation channel, and the end of the polymer prefabricated irrigation channel is cooled and shaped.

[0035] The end shaping device of the polymer prefabricated irrigation channel can heat and soften the end of the polymer prefabricated irrigation channel through a heating mechanism, so that the end of the polymer prefabricated irrigation channel is easy to deform, and after deformation and cooling, it is easy to shape. The open polymer prefabricated irrigation channel can be squeezed and shaped by clamping the polymer prefabricated irrigation channel with an upper mold and a lower mold. The upper mold and the lower mold are stacked by iron plates, so that the upper mold and the lower mold can be conveniently adjusted by adjusting the number of iron plates. The problem that the existing mold cannot shape the end of the open polymer prefabricated irrigation channel is solved. It is particularly suitable for shaping the polymer prefabricated irrigation channel.
