[0034] Example 1

[0035] See Figures 1 to 4 As shown, the hot bending and shaping apparatus provided in this application can be used for hot bending and shaping of acrylic glass. The apparatus includes a heating fixing seat and a pressure block 101. The heating fixing seat has an installation gap 103 to fix the bottom of the acrylic glass workpiece 102, and the heating fixing seat can heat the workpiece 102 so that its temperature reaches the deformation temperature of the acrylic glass material. For the aluminum foil suction conveyor guide plate, the deformation temperature is 256°C.

[0036] Of course, when hot bending and shaping workpieces made of other materials, the heating temperature of the heating fixture is set according to the specific deformation temperature of the material.

[0037] The heating fixture has an opening 104 communicating with the mounting gap 103. The workpiece 102 can be inserted into the mounting gap 103 through the opening 104 to fix the workpiece 102. In addition to facilitating the placement of the workpiece 102 in the mounting gap 103, the opening 104 also positions the pressure block 101. Specifically, the opening 104 gradually widens in the direction away from the mounting gap 103. The widened structure of the opening 104 provides space for the placement of the pressure block 101. In order to bend the workpiece 102, the pressure block 101 can be placed between the workpiece 102 and the side wall of the opening 104 to apply pressure to the workpiece 102. When the workpiece 102 reaches the deformation temperature, the workpiece 102 can bend towards the side wall of the opening 104 under pressure.

[0038] The hot bending and shaping device provided in this application, by setting a heating fixing seat and a pressure block 101, can quickly hot bend and shape the workpiece 102, with controllable deformation temperature and stable deformation effect. The device is compact and can be directly taken to the production site to perform flaring deformation of aluminum foil paper suction conveyor guide plates, thereby enabling timely verification of the bending effect of the workpiece 102, and personalized adjustments after feedback to adapt to different machines.

[0039] In an optional embodiment, the heating fixture includes two connected fasteners 105; the two fasteners 105 are arranged opposite to each other, and an installation gap 103 and an opening 104 are formed between the two fasteners 105. Figure 1 The two fasteners 105 shown are provided with a plurality of connecting holes 106, and the two fasteners 105 can be detachably connected by bolts. Furthermore, the distance between the two fasteners 105 can be adjusted to adjust the size of the installation gap 103 and the opening 104, thereby enabling hot bending forming of workpieces 102 of different sizes.

[0040] Of the two fasteners 105, at least one fastener 105 is formed of a thermally conductive material, specifically aluminum. At least one side of the workpiece 102 can be heated, meaning the workpiece 102 can be bent towards the heated side. The fastener 105 formed of the thermally conductive material can be connected to a temperature control device 110 to adjust the temperature of the heated fastener 105. A pressure block 101 can be placed between one of the fasteners 105 and the workpiece 102 to bend the workpiece 102 towards the other side and towards the fastener 105 formed of the thermally conductive material.

[0041] Optionally, one of the two fasteners 105 is made of a thermally conductive material, while the other fastener 105 is made of a non-thermally conductive material. This allows for single-sided heating and bending of the workpiece 102, making it easier to control the bending of the workpiece 102.

[0042] Furthermore, a heat insulation layer 107 is provided at the connection between the two fasteners 105 to prevent the heated fastener 105 from conducting heat to the fastener 105 on the other side. Specifically, the heat insulation layer 107 can be an asbestos gasket, a fiberglass layer, a rock wool layer, etc.

[0043] In an optional embodiment, the fixing member 105, which is formed of thermally conductive material, is further provided with an adjusting member 108; the adjusting end of the adjusting member 108 can extend and retract relative to the side wall of the opening 104 of the fixing member 105 to limit the bending position of the workpiece 102.

[0044] In this embodiment, when the workpiece 102 bends towards the side wall of the fixing member 105 under the action of the pressure block 101, the workpiece 102 is at its maximum bending angle when it is in contact with the side wall of the fixing member 105. The function of the adjusting member 108 is to adjust the bending degree of the workpiece 102. The abutting part of the adjusting member 108 can extend and retract relative to the side wall surface of the opening 104 of the fixing member 105. When the workpiece 102 bends towards the side wall of the fixing member 105, when the workpiece 102 abuts against the abutting part of the adjusting member 108, the workpiece 102 can no longer increase its bending angle, thereby realizing the adjustment of the bending angle of the workpiece 102.

[0045] For example, when hot bending an aluminum foil suction conveyor guide plate, the deformation temperature is 256℃, the deformation angle is 16°, and the deformation height is 12mm. The deformation height is determined by the groove depth of the installation gap 103.

[0046] Figures 1 to 4 The adjusting member 108 shown is an adjusting screw, which is rotated from the outside to the inside of the fixing member 105 to adjust the size of the abutment portion extending out of the inner wall of the fixing member 105. At least one adjusting screw is provided. For workpieces 102 with a large area, multiple adjusting screws act simultaneously to ensure more stable abutment support for workpieces 102.

[0047] Example 2

[0048] The hot bending and shaping device in this embodiment is an improvement on the above embodiments. The technical content disclosed in the above embodiments will not be described again, and the content disclosed in the above embodiments also belongs to the content disclosed in this embodiment.

[0049] See Figures 1 to 4 As shown, in an optional embodiment, the installation gap 103 is a groove structure. When the workpiece 102 is placed into the installation gap 103, the bottom of the workpiece 102 can be placed at the bottom of the groove structure, making the installation of the workpiece 102 more stable. The length direction of the opening 104 is consistent with the length direction of the groove structure, which facilitates the placement of the plate-shaped workpiece 102 into the installation gap 103 through the opening 104. The side wall of the opening 104 is a slope. When the plate-shaped workpiece 102 is bent to its maximum angle, the workpiece 102 can fit against the side wall of the opening 104, so that the bent shape of the workpiece 102 is regular. The groove opening of the groove structure is connected to the small-sized end of the opening 104, and a bending edge is formed between the groove opening of the groove structure and the opening 104. The position of the bending edge corresponding to the workpiece 102 is the bending point of the workpiece 102.

[0050] Specifically, Figure 2 and Figure 4 The dimensions of the heating fixture are shown in detail. The heating fixture is 108mm high, the bottom of the fixture is 45mm thick, the heating fixture holding the heat insulation layer is 94mm thick, the contact surface between the fixtures is 30mm high, and the side wall of the opening 104 is inclined at an angle of 108° relative to the top surface, which can be used to bend the aluminum foil paper suction conveyor guide plate.

[0051] In this embodiment, the pressure block 101 is a cylindrical structure, and the curved surface of the cylindrical structure is the pressure surface. During the bending process of the workpiece 102 under pressure, the curved surface of the pressure block 101 can fit against the plate surface of the workpiece 102, and the pressure block 101 can roll downward along the side wall of the opening 104 of the fixing member 105 under the action of gravity, continuously applying pressure to the workpiece 102. There is no need to manually apply pressure to the pressure block 101, and the stress on the workpiece 102 is more stable and uniform.

[0052] When hot bending the aluminum foil paper suction conveyor guide plate, the pressure block 101 is a cylinder with a diameter of 20mm. The material of the pressure block 101 is steel and its weight is 2kg.

[0053] During actual operation of the device, as the pressure block 101 rolls downward to apply pressure to the workpiece 102, the movement of the pressure block 101 is prone to jamming. Further, see... Figure 3 As shown, to increase the downward force of the pressure block, pull elastic elements 118 are provided at both ends of the pressure block 101. The pull elastic elements 118 are rotatably connected to the pressure block 101 and do not affect the rolling of the pressure block 101. The pull elastic elements 118 are used to apply a force to the pressure block in the direction of the installation gap 103. Under the combined force of gravity and the pulling force applied by the pull elastic elements 118, the pressure block 101 can roll in the direction of the installation gap 103 to perform a bending operation on the workpiece 102.

[0054] Of course, to prevent excessive impact force on the workpiece 102 during downward movement of the pressure block 101, which could damage the workpiece 102, a buffer structure can be added along the movement path of the pressure block 101. Specifically, see... Figure 4 As shown, near the extreme position of the falling block 101, a mounting groove is provided on the fixing member 105. A floating support plate 119 can be installed in the mounting groove. The floating support plate 119 is installed in the mounting groove by an elastic member, and the floating support plate 119 extends out of the surface of the inner side wall of the fixing member 105. When the block 101 falls, the floating support plate 119 can float up and down and apply a floating support force to the block 101, at least offsetting part of the impact force generated by the falling block 101. However, the floating support force will not completely offset the weight of the block 101, causing the block to be unable to continue falling. The above structure allows the block 101 to fall to different positions to achieve different bending angles of the workpiece 102.

[0055] In this optional embodiment, the hot bending and shaping device also includes a base 109. Both fixing members 105 of the heating fixing seat are installed on the base 109, specifically secured with bolts. Furthermore, at least one heat-generating part of the heating fixing seat is provided between itself and the base 109. That is, if both fixing members are heat-generating, then heat insulation layers must be provided between both fixing members and the base 109; if only one of the fixing members is heat-generating, then only one heat insulation layer needs to be provided between the heat-generating fixing member and the base 109. Specifically, the heat insulation layer can be an asbestos gasket, a fiberglass layer, a rock wool layer, etc.

[0056] Furthermore, the base 109 is made of heat-resistant materials, such as bakelite, heat-resistant plastic, etc.

[0057] Example 3

[0058] Embodiment 3 of this application provides a processing device, including the hot bending and shaping device of any of the above embodiments, and thus has all the beneficial technical effects of the hot bending and shaping device of any of the above embodiments, which will not be repeated here.

[0059] In an optional embodiment, the processing equipment further includes a temperature control device 110, whose heating element 111 is connected to a fixing member 105 made of a thermally conductive material. Optionally, the temperature control device 110 is also mounted on the top surface of the base 109.

[0060] See Figure 2 and Figure 4 As shown, in this embodiment, the two end faces of the fixing member 105 along the length direction are provided with insertion holes 112 with a diameter of 7mm. The heating tube 111 can be inserted into the fixing member 105 through the insertion holes 112. The heating tube 111 has a voltage of 110V, a power of 300W, and a length of 85mm.

[0061] Optionally, the temperature control device 110 is also equipped with a fuse 115, which serves to connect the input circuit in the switching power supply. In the event of an overload or short circuit fault, if the current through the fuse 115 exceeds the fusing current, the fuse will melt and disconnect the input circuit, thereby providing overcurrent protection.

[0062] In this optional embodiment, the temperature sensing element 116 of the temperature control device 110 is placed at the connection between the mounting gap 103 and the opening 104 to measure the temperature at the connection point. Specifically, the temperature sensing element 116 measures the temperature of the bent edge, which is more significant for determining the bending of the workpiece 102. The temperature sensing element 116 is specifically an E-type thermocouple. E-type thermocouples have a large thermoelectric potential and high sensitivity, allowing them to measure minute temperature changes. E-type thermocouples also have advantages such as good stability, superior oxidation resistance compared to copper-constantan and iron-constantan thermocouples, and lower cost.

[0063] The following describes the process of processing aluminum foil paper into a suction conveyor guide plate using processing equipment:

[0064] Connect the input power supply 117 of the temperature control device 110, turn on the power switch 113, and adjust the digital display temperature controller 114 of the temperature control device 110 to set the deformation temperature to 156℃. After the aluminum heating fixture reaches the set temperature, insert the aluminum foil suction conveyor guide plate into the installation gap 103, adjust the position of the adjusting screw extending out of the inner wall of the fixing member 105 to set the deformation angle to 16°, place the pressure block 101 between the aluminum foil suction conveyor guide plate and the fixing member 105, and perform plastic deformation on the aluminum foil suction conveyor guide plate for 8 minutes. Turn off the power switch 113, wait for the heating fixture to cool to room temperature, remove the pressure block 101, and then you can take out the aluminum foil suction conveyor guide plate that has been deformed.
