Description

Technical Field

[0001] The utility model relates to the field of glass processing, in particular to a flexible shaft glass bending equipment and a glass bending and tempering roller. Background Art

[0002] The existing flexible shaft glass bending equipment generally has multiple or even dozens of flexible shafts, and each flexible shaft has dozens of rollers, which means that the flexible shaft glass bending equipment usually requires hundreds to thousands of rollers. Most of the existing rollers are one-piece structures customized according to the diameter of the flexible shaft. The rollers are spaced and mounted on the flexible shaft. The flexible shaft and the rollers are fixed together by bonding with adhesives, tightening with tapered sleeves, etc. However, in the normal production process, the non-metallic materials on the surface of individual or partial rollers are easily damaged by high-temperature glass. When replacing, the rollers at the end need to be removed first until they are removed to the position of the rollers that need to be replaced. The rollers are difficult to remove and the number of rollers to be removed is large, resulting in low efficiency in roller replacement. The intact rollers are also easily damaged during the disassembly process, and the replacement cost is high; repeated disassembly and assembly will also affect the flexible shaft, or even damage it. Summary of the invention

[0003] In view of this, the first purpose of the utility model is to provide a glass bending and tempering roller, and the second purpose of the utility model is to also provide a soft-shaft glass bending and tempering equipment.

[0006] The beneficial effect is that the wheel body of the roller of the utility model is a split structure composed of two arc-shaped wheel cores, and the wheel body and the flexible shaft are detachably connected by fasteners (which can be screws or bolts). On the basis of ensuring that the clamping force and the bearing force are in the same vertical line, any roller on the flexible shaft can be quickly disassembled and assembled, thereby improving the replacement efficiency and reducing the replacement cost. In addition, a gap is designed between the two arc-shaped wheel cores, so that they can be clamped on the flexible shaft by fasteners, effectively ensuring the fixing effect.

[0008] In another preferred embodiment of the utility model, there are two mounting grooves, one mounting groove is provided on each wheel core, and the two mounting grooves are located on both sides of the center of the wheel body.

[0009] Preferably, the mounting groove is a through groove formed on the wheel core, but the mounting groove may be a non-through groove.

[0010] Preferably, an auxiliary mounting hole coaxial with the mounting groove is provided on the wheel core, and the auxiliary mounting hole is convenient for the hexagonal wrench to pass through, thereby enabling rapid installation of the fastener.

For those skilled in the art, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0021] Implementation Method 1

[0022] like Figure 1 As shown, the glass bending and tempering roller of the utility model comprises a wheel body and a high temperature resistant layer 1 wound around the outer peripheral surface of the wheel body, the wheel body comprises a pair of wheel cores 2 of arc structure, the two wheel cores 2 have arc holes 3 consistent with the radius of the flexible shaft, there is a gap of 0.2mm to 1.5mm between the connecting surfaces of the two wheel cores 2, and the two wheel cores 2 are fastened to the flexible shaft by two fasteners (screws 4 in this embodiment);

[0023] The two wheel cores 2 are close to a semicircular structure, so that there is a gap between the two wheel cores 2, which can be clamped on the flexible shaft by screws 4, effectively ensuring the fixing effect; the wheel core 2 located at the top is symmetrically provided with two mounting grooves 5 along its vertical center axis (the mounting grooves 5 in this embodiment are non-through grooves), and the wheel core 2 is provided with auxiliary mounting holes 6 that match the mounting grooves 5, and the aperture of the auxiliary mounting holes 6 is 2 mm to 5 mm. During actual installation, the screws 4 can be placed in the mounting grooves 5, and the hexagonal wrench can be passed through the auxiliary mounting holes 6 from top to bottom. The screws 4 can be screwed into the wheel core 2 below with the help of the hexagonal wrench, and then the wheel body can be clamped on the flexible shaft, ensuring that the clamping force between the two wheel cores 2 and the flexible shaft and the bearing force of the wheel body are on the same vertical line.

[0024] To ensure the concentricity of the flexible shaft and the wheel body, coaxial mounting holes are provided on the bottom wall of the mounting groove 5 and on another wheel core 2. When actually installing, the screw 4 is placed in the coaxial mounting hole from top to bottom, and then tightened with a wrench.

[0025] Combination Figure 1 It can be seen that a limiting groove is provided on the outer peripheral surface of the wheel body, and the high temperature resistant layer 1 is a high temperature resistant fiber belt or a high temperature resistant fiber rope arranged in the limiting groove, and the high temperature resistant layer 1 extends the fiber groove outward to avoid direct contact between the wheel body and the glass, thereby protecting the wheel body and extending its service life.

[0026] In actual processing, the outer diameter of the wheel body of the utility model is 43 mm to 75 mm, and the thickness of the wheel body is 6 mm to 16 mm, so as to reduce the contact area between the roller and the flexible shaft as much as possible; the diameter of the arc hole 3 is 10 mm to 30 mm, so as to ensure its concentricity with the flexible shaft.

[0027] During actual installation, the two wheel cores are placed on the flexible shaft respectively, and then the two wheel cores 2 are connected together with screws 4; when replacement is required, the screws 4 on the roller to be replaced are unscrewed and a new roller is replaced. There is no need to remove the rollers from the flexible shaft one by one, thereby achieving quick replacement.

[0028] The wheel body of the roller of the utility model is a split structure composed of two wheel cores 2 of arc-shaped structures. The wheel body and the flexible shaft are detachably connected by screws 4. On the basis of ensuring that the clamping force and the bearing capacity are in the same vertical line, any roller on the flexible shaft can be quickly disassembled and assembled, thereby improving replacement efficiency and reducing replacement costs.

[0029] Implementation Method 2

[0030] The difference between this embodiment and the first embodiment is that the mounting groove 5 is different.

The horizontal distances from the two mounting grooves 5 to the center of the wheel body are equal, and the distances from the two mounting grooves 5 to the horizontal center line are equal, so that the wheel body is tightly held on the flexible shaft to ensure that the force between the wheel body and the flexible shaft is balanced. At the same time, each wheel core 2 is provided with an auxiliary mounting hole 6 with the same central axis as the mounting groove 5 to meet the needs of rapid disassembly and assembly of the flexible shaft and the wheel body.

[0033] Implementation Method 4

[0034] The difference between this embodiment and the third embodiment is that the mounting groove 5 is different. Figure 4 It can be seen that the two mounting slots 5 of the present invention are through slots, so that the screws 4 can be put into the mounting holes from any side, which is convenient for installation.
