Description

Technical Field

[0001] The present invention relates to the technical field of fasteners, and particularly relates to a high-strength reinforcing rib hoop and a manufacturing method thereof. Background Art

[0002] Hoops are generally made of metal materials. Commonly, steel plates and steel strips are bent and processed into ring-shaped or semi-circular structures. Their inner diameters are slightly larger than the outer diameters of the objects to be fixed so that they can be sleeved on the objects. The working principle of the hoop is based on friction and clamping force. The patent with application number CN201821600126.2 discloses a hoop for communication, which includes a left hoop and a right hoop. The left hoop includes a left arc-shaped hoop body, a first left ear plate and a second left ear plate respectively connected to both ends of the left arc-shaped hoop body. A left pin shaft is provided on the inner side surface of the first left ear plate, and a left embedding groove is opened on the inner side surface of the second left ear plate. The right hoop includes a right arc-shaped hoop body, a first right ear plate and a second right ear plate respectively connected to both ends of the right arc-shaped hoop body. The first right ear plate corresponds to the first left ear plate, and a right embedding groove matching the left pin shaft is opened on the first right ear plate. The left pin shaft can be embedded in the right embedding groove to fix the first left ear plate and the first right ear plate. The second right ear plate corresponds to the second left ear plate, and a right pin shaft matching the left embedding groove is provided on the second right ear plate. The right pin shaft can be embedded in the left embedding groove to fix the second right ear plate and the second left ear plate. A surface insulation and voltage-resistant layer made of irradiated cross-linked polyethylene heat-shrinkable material with hot melt adhesive is coated on the outer surfaces of the left hoop and the right hoop. The surface insulation and voltage-resistant layer includes an outer PE layer, a reinforcing mesh layer, an inner PE layer and a hot melt adhesive layer which are distributed in sequence from outside to inside. A convex platform protruding outwards is provided in the middle of the right arc-shaped hoop body, and a convex platform threaded hole is opened in the center of the convex platform. A standard threaded hole is respectively opened on the first left ear plate, the second left ear plate, the first right ear plate and the second right ear plate, and the first left ear plate and the first right ear plate, as well as the second left ear plate and the second right ear plate are also reinforced by standard bolts. A galvanized layer is coated on the outer surfaces of the left hoop and the right hoop, and the surface insulation and voltage-resistant layer is coated on the outer surface of the galvanized layer. The left hoop and the right hoop are made of Q235 ordinary carbon structural steel. However, when the hoop is installed on an object with a slightly larger outer diameter, the left pin shaft cannot reach the inside of the right embedding groove, and the right pin shaft cannot reach the inside of the left embedding groove. The left pin shaft and the right pin shaft lose their functions, and there is a lack of protection at the bending part between the hoop and the ear plate. The bending part is prone to deformation under force, reducing the overall strength of the hoop. Summary of the Invention

[0003] The present invention aims to solve the problems existing in the above-mentioned prior art, and provides a high-strength reinforcing rib hoop and a manufacturing method thereof, which can set reinforcing ribs to improve the force-bearing capacity, integrally form to eliminate the welding process, increase the overall strength of the hoop to improve stability, reduce the occurrence of deformation during use, and has a simple structure and is convenient to operate.

[0004] Technical solution adopted by the present invention to solve its technical problems: This high-strength reinforcing rib hoop and its manufacturing method include a first arc-shaped member and a second arc-shaped member. An ear block is provided on the side of the first arc-shaped member. There are two ear blocks. Mounting holes are provided on the surface of the ear blocks. A reinforcing rib is provided on the surface of the first arc-shaped member, and the reinforcing rib extends to the surface of the ear blocks. The mounting holes penetrate the reinforcing rib. A first pressing groove is provided on the inner side of the first arc-shaped member, and the first pressing groove corresponds to the reinforcing rib. The second arc-shaped member is also provided with ear blocks, mounting holes, reinforcing ribs and a first pressing groove. A mounting bolt is provided on the side of the ear block. The mounting bolt sequentially passes through the mounting holes of the first arc-shaped member and the mounting holes of the second arc-shaped member. A nut is threadedly connected to the surface of the mounting bolt, and the nut abuts against the side of the ear block of the second arc-shaped member. There are two mounting bolts and two nuts respectively. A convex platform is provided on the surface of the second arc-shaped member. A connection hole is provided on the surface of the convex platform. A connection bolt is provided inside the connection hole. Obtain the first arc-shaped member and the second arc-shaped member. Pass the connection bolt through the connection hole from the inner side of the second arc-shaped member, and the front end of the connection bolt reaches the surface of the convex platform. The inner sides of the first arc-shaped member and the second arc-shaped member are respectively attached to the surface of the fixed object. The two ear blocks of the first arc-shaped member correspond to the two ear blocks of the second arc-shaped member. The two pairs of mounting holes correspond to each other. The two mounting bolts respectively pass through the two pairs of mounting holes. The two nuts are respectively threadedly connected to the two mounting bolts. The reinforcing rib strengthens the bending part between the first arc-shaped member and the ear block. The reinforcing rib strengthens the bending part between the second arc-shaped member and the ear block. The force on the first arc-shaped member, the second arc-shaped member and the ear block is effectively improved. Tighten the nut and the mounting bolt, and the hoop is effectively installed and fixed as a whole. Connect and install other support components and other nuts on the connection bolt and set the circuit. The setting of the reinforcing rib improves the force. The integral molding eliminates the welding process, increases the overall strength of the hoop and improves the stability, and reduces the occurrence of deformation during use. The structure is simple and convenient to operate.

[0005] For further improvement, the first arc-shaped member and the second arc-shaped member are made of the same material, and the thicknesses of the first arc-shaped member and the second arc-shaped member are the same. The first arc-shaped member and the second arc-shaped member made of the same material and having the same thickness have similar forces, reducing force deviation.

[0006] For further improvement, a fillet is provided on the side of the ear block, and fillets are also provided on the reinforcing rib and the convex platform. The setting of the fillets reduces the sharp right-angle edges, improving the safety and comfort during the operation process.

[0007] For further improvement, a limiting block is provided inside the convex platform. The limiting block is on the side of the connection hole. One limiting block is provided on each of the left and right sides of the connection hole. The head of the connection bolt is clamped between the two limiting blocks. The connection bolt is stuck by the two limiting blocks, reducing the rotation of the connection bolt, enhancing the fixing effect of the connection bolt, facilitating the connection and installation of other support components and other nuts, and saving manpower and time to improve the operation efficiency.

[0008] For further improvement, there are multiple connection holes, connection bolts and limiting blocks respectively. A second pressing groove is provided on the surface of the convex platform, and there are multiple second pressing grooves. The multiple connection bolts increase the stress points, further facilitating the installation of other support components. The multiple second pressing grooves correspond to the multiple limiting blocks, and the multiple limiting blocks are formed while pressing out the multiple second pressing grooves.

[0009] For further improvement, a third arc-shaped member is provided on the side of the second arc-shaped member. The third arc-shaped member has the same structure as the second arc-shaped member. The third arc-shaped member is connected to the second arc-shaped member through installation bolts and nuts. The third arc-shaped member is also provided with a convex platform and connection bolts. Other support components can be installed on both sides of the hoop, further improving flexibility and increasing convenience. At the same time, the third arc-shaped member has the same structure as the second arc-shaped member, and the generality is relatively high.

[0010] For further improvement, a first washer is sleeved on the surface of the installation bolt, and a second washer is sleeved on the surface of the installation bolt. The head of the installation bolt acts on the first washer, and the nut acts on the second washer. There are two second washers and two first washers respectively. The second washer and the first washer increase effective protection, avoid the installation bolt and the nut acting directly on the reinforcing rib, and reduce the wear on the surface of the reinforcing rib.

[0011] A high-strength reinforcing rib hoop and its manufacturing method include the following steps:

[0012] S1. Stamping and forming: The metal raw material of the first arc-shaped member is strip-shaped. After the overall heating treatment of the raw material, it is placed in the lower die of the corresponding mold. The stamping machine drives the upper die to perform stamping, and at the same time, the arc-shaped edge, two ear blocks, two first pressing grooves and two reinforcing ribs of the first arc-shaped member are stamped out. Then the first arc-shaped member is taken out for cooling. The second arc-shaped member and the third arc-shaped member have the same structure, and the forming principle is also the same. The metal raw material of the second arc-shaped member is strip-shaped. After the overall heating treatment of the raw material, it is placed in the lower die of the corresponding mold. The stamping machine drives the upper die to perform stamping, and at the same time, the arc-shaped edge, two ear blocks, two first pressing grooves, two reinforcing ribs and a convex platform of the second arc-shaped member are stamped out. Then it is taken out and placed in another mold to stamp out multiple second pressing grooves and multiple limiting blocks. Then the second arc-shaped member is taken out for cooling;

[0013] S2. Hole drilling: The first arc-shaped member is placed and fixed on a special device, and the drilling machine is started to drill holes at the corresponding positions of the two ear blocks to obtain two installation holes. The second arc-shaped member is placed and fixed on a special device, and the drilling machine is started to drill holes at the corresponding positions of the two ear blocks to obtain two installation holes. The second arc-shaped member is taken off and then placed and fixed on another device, and the drilling machine is started to drill holes at the corresponding positions of the convex platform to obtain multiple connection holes;

[0014] S3. Trimming process: Remove the first arc-shaped piece and the second arc-shaped piece, and perform grinding treatment on the first arc-shaped piece and the second arc-shaped piece respectively. Grind out multiple rounded corners on the ear blocks and the sides of the reinforcing ribs, and grind out the inner planes of multiple pairs of limiting blocks. Then, overall trim and smooth and remove the excess burrs. Subsequently, perform cleaning treatment and drying treatment uniformly, and spray a protective coating as needed.

[0015] The beneficial effects of the present invention are as follows:

[0016] 1. By obtaining the first arc-shaped piece and the second arc-shaped piece, pass the connecting bolt through the connecting hole from the inside of the second arc-shaped piece. The front end of the connecting bolt reaches the surface of the boss. The inner sides of the first arc-shaped piece and the second arc-shaped piece are respectively attached to the surface of the fixed object. The two ear blocks of the first arc-shaped piece correspond to the two ear blocks of the second arc-shaped piece, and the two pairs of mounting holes correspond to each other. Two mounting bolts respectively pass through the two pairs of mounting holes, and two nuts are respectively threadedly connected to the two mounting bolts. The reinforcing ribs strengthen the bent parts between the first arc-shaped piece and the ear blocks, and the reinforcing ribs strengthen the bent parts between the second arc-shaped piece and the ear blocks. The stress of the first arc-shaped piece, the second arc-shaped piece and the ear blocks is effectively improved. Tighten the nuts and the mounting bolts, and the overall hoop is effectively installed and fixed. Connect and install other support components and other nuts on the connecting bolt and set the circuit. The setting of the reinforcing ribs improves the stress. The one-piece molding omits the welding process, increases the overall strength of the hoop and improves the stability, reduces the occurrence of deformation during use, and has a simple structure and is convenient to operate.

[0017] 2. The connecting bolt is clamped by two limiting blocks, reducing the rotation of the connecting bolt, enhancing the fixing effect of the connecting bolt, facilitating the connection and installation of other support components and other nuts, saving manpower and time, and improving the operation efficiency. Multiple connecting bolts increase the stress points, further facilitating the installation of other support components. Multiple second grooves correspond to multiple limiting blocks, and multiple second grooves are pressed out while forming multiple limiting blocks.

[0018] 3. Other support components can be installed on both sides of the hoop, further improving the flexibility and increasing the convenience. At the same time, the structure of the third arc-shaped piece is the same as that of the second arc-shaped piece, and the general degree is relatively high. The second washer and the first washer increase the effective protection, avoiding the direct action of the mounting bolt and the nut on the reinforcing rib, and reducing the wear on the surface of the reinforcing rib.

[0030] A high-strength reinforcing rib hoop and its manufacturing method include the following steps:

[0031] S1. Stamping and forming: The metal raw material of the first arc-shaped member 1 is strip-shaped. After the raw material is heated as a whole and placed in the lower die of the corresponding mold, the stamping machine drives the upper die to perform stamping, and at the same time stamps out the arc-shaped edge of the first arc-shaped member 1, two ear blocks 3, two first grooves 6 and two reinforcing ribs 5.

When it is necessary to install other support components on both sides of the clamp for wiring, replace the first arc-shaped member 1 with the third arc-shaped member 15. Pass the connecting bolt 11 through the connecting hole 10 from the inner side of the third arc-shaped member 15. The front end of the connecting bolt 11 reaches the surface of the boss 9 of the third arc-shaped member 15. The inner sides of the third arc-shaped member 15 and the second arc-shaped member 2 are respectively attached to the surface of the fixed object. The two mounting bolts 7 are first sleeved with the first washers 16, and after the two mounting bolts 7 respectively pass through the two pairs of mounting holes 4, they are then sleeved with the second washers 17.
