Description

Technical Field

[0001] The invention relates to the technical field of plastic pipe processing, in particular to a plastic pipe bending device. Background Art

[0002] Existing plastic pipes have certain shortcomings when they are bent. First, when the plastic pipe is bent, its hardness becomes lower after heating, and its plasticity is high at this time, but it will produce uncontrollable deformation, especially when subjected to external pressure, which will cause flattening or internal deformation, affecting the quality of the plastic pipe. Secondly, if particles or dust are attached to the surface or inside of the pipe when the plastic pipe bending equipment is bending, it will rub against the mold and other components during the bending process, causing scratches or wear on the pipe surface, affecting the quality of the pipe. Particles or dust attached to the surface or inside of the pipe may change the contact state between the pipe and the mold, resulting in uneven force on the pipe during the bending process, thereby affecting the accuracy and consistency of the bending.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] The present invention provides a plastic pipe bending device. By setting a bearing mechanism, an auxiliary mechanism and a punching mechanism, when the pipe is processed and bent, the preheated pipe interior is first supported to prevent it from deforming during heating. At this time, the elastic soft cloth bag, through the filling of hot particles, will be more adapted to the shape of the interior of the pipe.

[0011] Secondly, during shaping, the channel formed by the pressing assembly and the punching seat is used in conjunction with the auxiliary mechanism to generate airflow inside the channel to blow away the particles and dust on the surface and inside of the plastic pipe, thereby avoiding uneven force on the pipe during the bending process, which is beneficial to improving the quality of the pipe. At the same time, after blowing, the two sets of auxiliary mechanisms close the openings at both ends of the pipe and send the gas into the interior of the plastic pipe, so that it fits the semi-arc notch and the second semi-arc notch, thereby improving the fit of the mold;

[0012] During the bending process, the pipe is prone to deformation due to the influence of the mechanical properties of the material. In order to ensure that the roundness and diameter of the pipe are not affected, it is necessary to support the pipes on both sides during bending. At this time, the air guide components are set to prevent the pipes from being flattened or deformed during the bending process. The pipes on both sides are supported by the air guide pipe to facilitate the connection with other pipes later. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] See also Figure 2-Figure 11 The bearing mechanism includes a mounting seat 21 arranged at the top of the base 1. The outer surface of the mounting seat 21 is threadedly connected to a stamping seat 22 by bolts. A plurality of groups of semi-arc notches 23 are provided on the top of the stamping seat 22. The semi-arc notches 23 are provided to cooperate with the second semi-arc notches 431 above. When they are actually used, they need to be replaced and adjusted in time according to the different bending parameters of the produced pipes to avoid errors, and the number of the semi-arc notches 23 corresponds to the number of the second semi-arc notches 431.

[0028] The auxiliary mechanism includes an elevated plate 31 arranged at the top of the supporting mechanism, and the elevated plate 31 is provided with movable holes 32 corresponding to the number of the semi-arc grooves 23, and elastic soft cloth bags 33 are arranged at the edges of the movable holes 32. One side of the elevated plate 31 is provided with limiting components 34 corresponding to the number of the movable holes 32, and the other side of the elevated plate 31 is provided with limiting bottoms 35 corresponding to the number of the movable holes 32. The other side of the elevated plate 31 is fixedly connected with a propulsion component 36 for operating the elastic soft cloth bags 33, the interior of the elevated plate 31 is filled with heat-conducting particles 37, and the inner wall of the elevated plate 31 is provided with a plurality of groups of first heating plates 38.

[0029] An end of the limiting assembly 34 is fixedly connected to an orientation block 341 , and a top end of the orientation block 341 is fixedly connected to a slide rail 342 .

[0030] One side of the propulsion assembly 36 is fixedly connected to a driving motor 361, and one side of the propulsion assembly 36 is fixedly connected to a loading box 362 near the driving motor 361, and the other side of the propulsion assembly 36 is rotatably connected to a first rotating tooth 363, and the surfaces of the first rotating tooth 363 are respectively meshed with a pushing rod 365 and a pushing block 364, and the end of the pushing rod 365 is fixedly connected to a bent tube spring, and the end of the bent tube spring is fixedly connected to the inner wall of the other end of the opening of the elastic soft cloth bag 33, and the surface of the pushing rod 365 slides on the surface of the limiting bottom 35, and the output end of the driving motor 361 is fixedly connected to the first rotating tooth 363, and the bottom surface of the pushing block 364 slides on the top of the propulsion assembly 36, and a pushing block is fixedly connected to the edge of the bottom surface of the pushing block 364, and an air bag 366 is fixedly connected through the pushing block, and the air bag 366 is arranged inside the loading box 362, and one side of the pushing block 364 is rotatably connected to an air guide component 367.

[0031] The end of the air guide component 367 is rotatably connected to a diamond-shaped propulsion block 3671 , an air guide tube 3672 is arranged inside the diamond-shaped propulsion block 3671 , and a sliding groove is opened at the bottom end of the diamond-shaped propulsion block 3671 , which slides on the surface of the slide rail 342 .

[0032] The push block 364, the push block, the air bag 366 and the air guide component 367 are connected to each other, so when the air bag 366 is compressed, the gas can be passed into the air guide tube 3672 and then input into the plastic pipe. The air guide components 367 on both sides have different operating speeds to ensure that one group of air guide tubes 3672 blows first, and after part of the gas enters the opening on one side of the plastic pipe, the air is sent into the pipe by the air guide tube 3672 on the other side, making the molding more standard while accelerating the cooling of the mold. The air outlet end of the air guide tube 3672 will only guide and discharge air outward when the pressure reaches a certain level.

[0033] A triangular hole 44 is formed on the side wall of the protection plate 41 , and an observation glass is embedded inside the triangular hole 44 .

[0034] A plurality of groups of second semi-arc notches 431 are formed on the surface of the pressing component 43 , and a second heating plate 432 is disposed on the inner bottom of the pressing component 43 so as to be staggered with the second semi-arc notches 431 .

[0035] Specific working principle;

[0036] Place the plastic tube on the top of the punching seat 22 on the bearing mechanism, and align the center with the center of the semi-arc notch 23, start the cylinder 42 on the punching mechanism, and make the output end of the cylinder 42 drive the pressing assembly 43 to descend. When the pressing assembly 43 slowly descends, one of the auxiliary mechanisms provided with the elastic soft cloth bag 33 starts to work, and the first heating plate 38 first starts to preheat the heat-conducting particles 37 inside the elevated plate 31. At this time, the pressing assembly 43 has slowly descended to the upper part of the plastic tube;

[0037] The second semi-arc notch 431 of the pressing component 43 is vertically aligned with the semi-arc notch 23. At this time, the second heating plate 432 inside the pressing component 43 starts to heat the inside of the plastic tube. At the same time, the auxiliary mechanism provided with the elastic soft cloth bag 33 starts to work, and the driving motor 361 on the propulsion component 36 starts to start. At this time, the driving motor 361 drives the pushing rod 365 to start moving forward, and the bent pipe spring fixedly connected to the end of the pushing rod 365 moves forward at the same time. At this time, the heat-conducting particles 37 inside the elevated plate 31 are The bending tube spring is driven forward, and at the same time, the elastic soft cloth bag 33 is pushed forward, and the partially heated heat-conducting particles 37 are dispersed in the gap formed by the elastic soft cloth bag 33 and the bending tube spring. At the same time, the elastic soft cloth bag 33 enters the interior of the plastic tube to prevent the plastic tube from being deformed or bent on the surface after being softened by heating. When the elastic soft cloth bag 33 is completely in the internal cavity of the plastic tube, the cylinder 42 continues to drive the pressing component 43 downward, so that the plastic tube is in the interior of the semi-arc notch 23 and the interior of the cavity where the second semi-arc notch 431 is located. At this time, the cavities of the semi-arc notch 23 and the second semi-arc notch 431 are not completely closed, and the plastic tube has slowly been placed in the two unclosed cavities for preliminary shaping. Subsequently, the driving motor 361 on the propulsion assembly 36 drives the first rotating tooth 363 again to start operating, and the first rotating tooth 363 is used to return the push rod 365, and the push rod 365 pulls the elastic soft cloth bag 33 back through the bent tube spring. At the same time, the first rotating tooth 363 drives the push block 364 to move forward. During the forward pushing process, the push block 364 The airbag 366 inside the carrier box 362 is squeezed, and at this time, the push block 364 drives the air guide component 367 to push forward, so that the air guide component 367 pushes the diamond-shaped push block 3671 forward, and the diamond-shaped push block 3671 slides forward on the surface of the slide rail 342 to limit the position. When the diamond-shaped push block 3671 moves to one side of the plastic tube, the air flow is blown to the inside of the cavity of the plastic tube and the inside of the unclosed cavity, and the surface debris of the plastic tube is blown away through the narrow cavity. Then, the air guide tube 3672 partially enters the inside of the plastic tube;

[0038] Another auxiliary mechanism starts to operate, and also through the rotation of the first rotating tooth 363, the air bag 366 inside the loading box 362 is squeezed. At this time, the pushing block 364 drives the air guide component 367 to push forward, so that the air guide component 367 pushes the diamond-shaped pushing block 3671 forward. At this time, the cylinder 42 continues to operate downward, and the outer surface of the pressing component 43 is attached to the stamping seat 22, so that the cavity formed by the second semi-arc notch 431 and the semi-arc notch 23 is closed. At this time, the second heating plate 432 inside the pressing component 43 stops working, and the other air guide pipe 3672 fills the inside of the plastic pipe with gas. The pipes on both sides are stretched open to facilitate the connection with other pipes later, so that the pipes are fully formed and avoid bending.
