DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technical personnel in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figures 1 to 6The utility model provides a technical solution: a forming mold assembly with a heat treatment structure, including an operating table 1, a shaped frame 2 is welded on the surface of the operating table 1, and the shaped frames 2 are vertically aligned and internally connected with lead screws 3, the lead screws 3 are connected with connecting components 4 through nuts and bolts provided thereon, and the shaped frames 2 are plugged and connected with an upper pressure roller 5 and a lower pressure roller 6 through the connecting components 4, and an upper limit piece 7 and a lower limit piece 8 are provided at the top and bottom of the operating table 1, respectively, and the upper pressure roller 5 and the lower pressure roller 6 are located between the upper limit piece 7 and the lower limit piece 8, and the lower limit piece 8 is connected to an electric telescopic rod 9 through a slider provided at the bottom thereof, and the electric telescopic rod 9 is located on the inner wall at the bottom of the operating table 1, and a movable top frame 10 is connected to the top of the upper limit piece 7 by bolts, and the movable top frame 10 is slidably connected to the highest point of the operating table 1, and a middle limit piece 11 is glued and connected between the shaped frames 2, and the middle limit piece 11 is located between the upper pressure roller 5 and the lower pressure roller 6.

[0026] The connecting component 4 includes a left tenon groove 401 and a right tenon groove 402, which are respectively connected to nuts on the surface of the screw 3 through bolts, and the left tenon groove 401 and the right tenon groove 402 are respectively plugged and connected with tenons 403, which are respectively glued and connected to the axis at both ends of the outer wall of the upper pressure roller 5 and the lower pressure roller 6.

[0027] The upper limit member 7 includes an outer fixing plate 701 and an adjusting screw 702. The two ends of the outer fixing plate 701 are respectively penetrated by threaded through holes for threaded connection with the adjusting screw 702. The other end of the adjusting screw 702 is glued to the inside of the inner adjusting plate 703 through a bearing provided therein.

[0028] The middle limiting member 11 includes a reel 1101 , a clamping ring 1102 and a clamping column 1103 . The clamping column 1103 and the reel 1101 are arranged opposite to each other and are respectively located between the C-shaped frames 2 . The clamping ring 1102 is clamped and connected to the clamping column 1103 . The clamping ring 1102 is glued and connected to the front end of the reel 1101 .

[0029] In this embodiment, Figure 3 As shown, the lead screws 3 are connected by belts, and the upper pressure roller 5 and the lower pressure roller 6 form a horizontal transmission structure through the lead screw 3 and the nut respectively; the upper and lower groups of molds are used for shaping. When the raw material is fixed between the two, the transmission structure of the lead screw 3 can move relative to each other to extrude the raw material and then achieve bending. Since the transmission accuracy of the lead screw 3 is relatively high, the adjustment process is more accurate and controllable, and the curvature can be controlled by the transmission distance. By adjusting the curvature, products of different shapes and sizes can be produced, providing ultimate flexibility for the product.

[0030] In this embodiment, Figure 1 and Figure 2As shown, the diameter of the upper pressing roller 5 is smaller than that of the lower pressing roller 6, and the upper pressing roller 5 and the lower pressing roller 6 are made of metal and a resistance wire for heating is provided inside one side, and the outer side of the upper pressing roller 5 and the lower pressing roller 6 is covered with a heat insulating pad on the other side; it should be noted that the bamboo slice raw material is used to process bookshelves, and the two shaped bamboo slices can form a shape that is wide at the top and narrow at the bottom after being relatively glued and spliced. This combination is simple and beautiful, and is also convenient for the delivery of books and newspapers. Therefore, the upper pressing roller 5 with a smaller specification is located at the top, and the corresponding curvature caused is smaller than that at the bottom, so that the final formed bamboo slice has beauty. A heat insulating pad is arranged on the side of the upper pressing roller 5 and the lower pressing roller 6 adjacent to the external operator to prevent the operator from being accidentally burned by the high-temperature upper pressing roller 5 and the lower pressing roller 6.

[0031] In this embodiment, Figure 2 and Figure 5 As shown, the lower limit member 8 has the same structure as the upper limit member 7, and the inner adjustment plate 703 moves relative to each other inside the outer fixed plate 701 through the adjusting screw 702; in order to avoid the problem of displacement of the bamboo slices during extrusion and shaping by the upper pressing roller 5 and the lower pressing roller 6, which affects the shaping effect, anti-displacement structures are added at the upper and lower ends thereof, and the adjustable structures inside the upper limit member 7 and the lower limit member 8 can be adjusted accordingly according to the thickness of the bamboo slices, thereby improving the versatility of use of the equipment, and the inner adjustment plate 703 is made of rubber material, which can improve the friction and has a certain anti-slip performance.

[0032] In this embodiment, Figure 2 and Figure 4 As shown, the lower limit member 8 is slidably connected to the lowest point of the surface of the operating table 1 through the electric telescopic rod 9, and the upper limit member 7 is slidably connected to the highest point of the surface of the operating table 1 through the movable top frame 10; because the bamboo pieces themselves have certain specifications, and the upper pressing roller 5 and the lower pressing roller 6 occupy a certain area on the surface of the operating table 1, while not affecting the use efficiency of the upper limit member 7 and the lower limit member 8, it is also necessary to have the characteristics of convenient loading and unloading of bamboo pieces. Under the structure of the movable top frame 10 and the electric telescopic rod 9, the upper limit member 7 and the lower limit member 8 can slide along the Z axis and the X axis at the top and bottom of the operating table 1 respectively, reserving a certain space for loading and unloading of bamboo pieces.

[0033] In this embodiment, Figure 3 As shown, the depth of the through hole inside the left tenon groove 401 is greater than that inside the right tenon groove 402, and a spring is provided on the inner wall of the through hole of the left tenon groove 401; since the upper pressure roller 5 and the lower pressure roller 6 have heating resistance wires with heat treatment structures inside, maintenance may occur, and a spring is provided inside the left tenon groove 401 to improve the adaptability and compatibility of the connection for the disassembly of the tenon 403 between the two ends to prevent the upper pressure roller 5 and the lower pressure roller 6 from getting stuck during disassembly.

[0034] The use method and advantages of the utility model: When the shaping mold assembly with a heat treatment structure is used, the working process is as follows:

[0035] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, first, the bamboo piece material to be shaped is pre-fixed by the upper limit member 7, and according to the thickness of the bamboo piece, the adjusting screw rods 702 at both ends are rotated accordingly, so that the inner adjustment plates 703 are respectively attached and the upper end of the bamboo piece is clamped therein, and the lower limit member 8 is driven by the electric telescopic rod 9 to slide to the bottom of the bamboo piece, and the lower part of the bamboo piece is fixed in the same operation mode, and the clamping ring 1102 is pulled. The outer part of the reel 1101 is wrapped with a metal sheet of elastic material, and the clamping ring 1102 is clamped on the surface of the clamping column 1103. The bamboo piece material is fixed by the upper, middle and lower three groups of limiting structures, so that the subsequent bamboo piece can maintain a stable state when being squeezed by the upper pressing roller 5 and the lower pressing roller 6. After preheating the upper pressing roller 5 and the lower pressing roller 6, the lead screw 3 is driven by the upper and lower servo motors respectively, and the nuts on the surfaces of the two groups of lead screws 3 respectively drive the connecting assembly 4 to make the upper pressing roller 5 and the lower pressing roller 6 relatively transmitted. The operator can adjust the bamboo piece according to the thickness of the bamboo piece. The required curvature is appropriately adjusted to the distance transmitted by the upper pressing roller 5 and the lower pressing roller 6, and adjusted to the appropriate position, and the servo motor driving the screw 3 is stopped, and the upper pressing roller 5 and the lower pressing roller 6 perform heat treatment on the bamboo strips. Since the upper pressing roller 5 and the lower pressing roller 6 are made of metal and have good thermal conductivity, the bamboo strips are heated to a certain temperature, making them soft and having a certain plasticity. When the bamboo strips are squeezed by the upper pressing roller 5 and the lower pressing roller 6, they will be plastically deformed along the contours of the upper pressing roller 5 and the lower pressing roller 6 to obtain the required curved shape. After the shaping is completed, the middle limit member 11 is pre-disassembled, and the snap ring 1102 is separated. Since the spring spring structure of the prior art is added to the interior of the reel 1101, the reel will automatically complete the reeling after the fixation of the snap ring 1102 is lost, and then the upper limit member 7 and the lower limit member 8 are respectively disassembled, and a channel for taking materials is reserved for the bamboo strips after the upper limit member 7 slides by moving the top frame 10.

[0036] The above shows and describes the basic principle, main features and advantages of the utility model. Technical staff in this industry should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
