DETAILED DESCRIPTION

[0043] Advantages and features of the present invention will be illustrated and explained by the following non-limiting description of preferred embodiments thereof, which are given by way of example only with reference to the accompanying drawings.

[0044] like Figure 1 As shown, the present invention provides an anti-deformation arc-shaped wood-plastic fence board extrusion device, comprising an extrusion die 1 and a connecting mandrel 4 detachably connected to the extrusion die 1, wherein the connecting mandrel 4 is built into the extrusion die 1 and extends 100-150 mm outward from the mouth die of the extrusion die 1. The connecting mandrel 4 is made of alloy steel with relatively high hardness. A lining steel 5 is fixedly connected to the connecting mandrel 4, and the lining steel 5 is arc-shaped as a whole and tilted upward. The bending inclination angle of the lining steel 5 with the extrusion direction is 45°, and the bending radius is 0.75-1.15m. A connecting cross bar 9 is provided at one end of the lining steel 5 away from the connecting mandrel 4, and the connecting cross bar 9 can maintain the stability of the extrusion process. The lining steel 5 is preferably a solid steel sheet or a hollow steel pipe. During extrusion production, the wood-plastic fence board is bent along the lining steel 5 until it stops at the connecting cross bar 9. After the shaping is stabilized, the lining steel 5 can be removed from the connecting mandrel 4, thereby obtaining an anti-deformation arc-shaped wood-plastic fence board.

[0045] like Figure 2 and Figure 3As shown, the connecting mandrel 4 has two specifications, one specification can extrude a wood-plastic fence board 12 with four cavities 12, and the other specification can extrude a wood-plastic fence board 23 with two cavities 12. The number of the lining steels 5 is consistent with the number of cavities 12 of the wood-plastic fence board, that is, when producing the wood-plastic fence board 12, four lining steels 5 are connected to the connecting mandrel 4, and when producing the wood-plastic fence board 23, two lining steels 5 are connected to the connecting mandrel 4.

[0046] like Figure 4 and Figure 5 As shown, for easy assembly, a male groove 10 is provided on one side of the width direction of the wood plastic fence board 2, and a female groove 11 is provided on the other side, wherein the male groove 10 protrudes outward and the female groove 11 is recessed inward. Female grooves 11 are provided on both sides of the width direction of the wood plastic fence board 23.

[0047] like Figure 6 and Figure 7 As shown, in order to facilitate the disassembly and fixation between the lining steel 5 and the connecting core rod 4, a connecting steel sheet 8 with a length of 60-80 mm is fixedly connected to the end of the lining steel 5 close to the connecting core rod 4, and a slot is provided at the end of the connecting core rod 4 away from the extrusion die 1, and the connecting steel sheet 8 is inserted into the slot to connect with the connecting core rod 4. The connecting steel sheet 8 is made of high-hardness alloy steel. In order to relatively fix the lining steel 5 and the connecting core rod 4 so that they will not be disengaged during the production process, a plurality of positioning holes 7, preferably two, are provided at the corresponding positions of the connecting steel sheet 8 and the connecting core rod 4, and the connecting fixture 6 is inserted into the positioning hole 7 for positioning. The connecting fixture 6 is preferably a combination of one or both of a hexagonal bolt and a pin.

[0048] like Figure 8 and Fig.10As shown, the WPC fence board 1 2 and the WPC fence board 2 3 are quickly installed by connecting the base 13, the connecting column 14, the connecting crossbar 15, the spacer buckle 16 and the cap 17. The connecting base 13 is fixedly connected to the ground, preferably fixedly connected to the ground by expansion bolts. The connecting column 14 is an aluminum square column, and the square bottom surface of the connecting column 14 is fixedly connected to the connecting base 13 by bolts. Three of the four side surfaces of the connecting column 14 are provided with grooves 20 for clamping the WPC fence board 1 2 and the WPC fence board 2 3. The connecting crossbar 15 is fixedly connected to the connecting column 14 by aluminum alloy angle code and bolts. The WPC fence board 1 2 or WPC fence board 2 3 are placed in the groove 20 from bottom to top. When the WPC fence board 1 2 is placed, the upper and lower connections can be realized through the male groove 10 and the female groove 11 provided by the WPC fence board 1 2; when the WPC fence board 2 3 or two WPC fence boards are placed and connected in combination, it is necessary to place the spacer buckle 16 at the joint position of the two female grooves 11 to realize the upper and lower buckle of the WPC fence board 2 3 and the mutual buckle of the two WPC fence boards. When the WPC fence board 1 2 and the WPC fence board 2 3 are placed, a connecting horizontal bar 15 is placed thereon, and fixedly connected to the upper end of the connecting column 14 by an aluminum alloy angle code and bolts. The top of the connecting column 14 is connected with a cap 17, and the cap 17 is used to prevent dust, rainwater, etc. from accumulating in the groove 20 or the hollow part of the connecting column 14, thereby causing corrosion of the WPC fence board and affecting its life. After the cap 17 is added to the top of the connecting column 14, the assembly of a single group of WPC fence products is completed. If multiple groups of WPC fences need to be installed, the grooves 20 on the connecting posts 14 can be used to achieve this, and the angle between adjacent grooves 20 is 90°. Therefore, after installing one group of WPC fences, another group can be installed at the adjacent or opposite grooves 20 at one end of the connecting post 14, and the remaining grooves 20 are placed in the aluminum column edge sealing for edge sealing treatment, thereby achieving the arc-shaped WPC fence effect with different angles to adapt to different use conditions and enhance a certain degree of ornamental value.

[0049] like Fig. 9 As shown, it is the first assembly method of multiple groups of wood-plastic fence finished products, wherein the arc center of each group of wood-plastic fence is on the same side and on the same straight line. In this way, adjacent groups of wood-plastic fence are placed in adjacent grooves 20. This assembly method allows several groups of wood-plastic fence finished products to be combined into an M shape.

[0050] like Fig.10 As shown, it is a second assembly method of multiple groups of wood-plastic fence finished products, wherein adjacent wood-plastic fences are placed in opposite grooves 20, and the arc centers of each group of wood-plastic fences are staggered on both sides. This assembly method allows several groups of wood-plastic fence finished products to be combined into a sine waveform.

[0051] like Fig.11As shown, it is a third way to assemble multiple groups of finished wood-plastic fences, wherein adjacent wood-plastic fences are placed in opposite grooves 20, and the arc center of each group of wood-plastic fences is on the same side. This assembly method can enclose several groups of finished wood-plastic fences into a circle.

[0052] Fig.12 This is the second assembly method of a single-group wood-plastic fence finished product of the present invention. This assembly method is that a plurality of wood-plastic fence panels 1 2 are spliced ​​together through the male groove 10 and the female groove 11.

[0053] Fig.13 This is the third assembly method of a single-group wood-plastic fence finished product of the present invention. In this assembly method, a plurality of wood-plastic fence panels 2 3 are spliced ​​together through the mother groove 11 and the spacer buckle 16.

[0054] Fig.14 Adjacent groups of wood-plastic fences are placed in adjacent grooves 20, and a single group of wood-plastic fences is assembled by a wood-plastic fence board 1 2, a wood-plastic fence board 2 3 and a spacer buckle 16 that cooperate and snap together.

[0055] The present invention also provides an assembly method for the anti-deformation curved wood-plastic fence of the present invention, comprising the following steps:

[0056] Step 1: Fix the connection base 13 to the ground.

[0057] Step 2: The square bottom surface of the connecting column 14 is fixedly connected to the connecting base 13 by bolts.

[0058] Step 3: Connect the connecting horizontal bar 15 to the lower end of the connecting column 14 through aluminum alloy angle brackets and bolts.

[0059] Step 4: Place the WPC fence board 1 2 or the WPC fence board 2 3 in the groove 20 from bottom to top. When the male groove 10 is connected with the female groove 11, they are directly spliced; when the female groove 11 is connected with the female groove 11, they are spliced ​​through the spacer buckle 16.

[0060] Step 5: After the WPC fence board 1 2 or the WPC fence board 2 3 is placed, a connecting horizontal bar 15 is placed thereon and fixedly connected to the upper end of the connecting column 14 by means of aluminum alloy angle codes and bolts.

[0061] Step 6: Add a cap 17 to the top of the connecting column 14, and the assembly of a single set of wood-plastic fence finished product is completed.

[0062] Step 7: Install another set of wood-plastic fences at the positions of the grooves 20 adjacent to or opposite to the connecting posts 14 as needed.

[0063] Step 8: After the wood-plastic fence is assembled, aluminum columns are placed in the remaining grooves 20 for edge sealing.

[0064] In addition to the above embodiments, the present invention may also have other implementation modes. Any technical solutions formed by equivalent replacement or equivalent transformation shall fall within the protection scope required by the present invention.
