Description

Technical Field

[0001] The utility model relates to the technical field of steel straightening equipment related equipment, and more specifically, particularly relates to a straightening roll assembly and a straightening machine. Background Art

[0002] A straightening machine is equipment for straightening metal profiles, bars, pipes, wires, etc. The straightening machine extrudes bars and the like through straightening rolls to change their straightness. At present, straightening machines generally have two rows of straightening rolls, and the number of single-row straightening rolls varies. There are also two-roll straightening machines that rely on the angle change of two rolls (concave in the middle, hyperbolic rolls) to straighten materials of different diameters. However, for the current traditional stretch-bending straightening rolls, the straightening rolls used in straightening machines will be worn during use, and after a period of use, the straightening rolls often need to be replaced.

[0003] The prior art has the following defects and deficiencies: Replacing the straightening rolls of the existing straightening machine requires using a lot of tools to disassemble the straightening rolls, which is very troublesome, wastes a lot of time, and has low work efficiency. For example, replacing the straightening rolls of a traditional simply supported structure roll-type straightening machine requires disassembling mechanical equipment, and the replacement time of the straightening rolls is up to one day, affecting the normal production rhythm of the enterprise and resulting in low production efficiency.

By rotating the locking member 301, the locking member 301 can axially move along the axis of the lower roller 5 at the shaft end of the lower roller 5. The locking member 301 can convert the horizontal movement into expansion towards the outer ring (the outer ring is the fastening clip 302) or contraction towards the inner ring, and the locking member 301 is detachably connected to the lower roller 5. The fastening member 302 is arranged outside the locking member 301, and the fastening member 302 has a surface that is in sliding contact with the locking member 301 (the contact surface is an inclined surface, which can convert the axial movement of the locking member 301 into a radial expansion or contraction movement), and the fastening member 302 is detachably connected to the lower roller 5 (specifically, an annular protrusion is arranged at one end of the lower roller 5 for installing the locking member 301, and sliding holes are equidistantly arranged on the annular protrusion, and the fastening member 302 is installed in the sliding holes and cooperates with the locking member 301).

[0048] As Figure 2 shown, the installation mechanism further includes a connection seat 102, an installation frame 103, and an installation seat 101. The driving mechanism is installed above the installation seat 101 and below the connection seat 102; the installation seat 101 is fixedly connected to the driving mechanism, and the fixed connection method can be screw connection or welding, preferably, the driving structure and the installation seat 101 are screw-connected.

[0049] The connection seat 102 is located at the upper part of the installation mechanism. Specifically, the connection seat 102 is located above the installation seat 101 and is used to fixedly install the upper roller 4, and the upper roller 4 is installed on the connection seat 102; the installation frame 103 is fixedly installed above the installation seat 101, and the installation frame 103 is arranged at one end of the lower roller 5 and is used to fixedly support the lower roller 5. The installation seat 101 is used to fixedly install the connection seat 102 and the installation frame 103, and the installation frame 103 is fixedly connected to the installation seat 101; the connection method can be screw connection or welding, preferably, the installation frame 103 and the installation seat 101 are screw-connected.

[0050] The installation seat 101 is a housing, and its upper surface is a flat plane. The shape of this upper surface can be polygonal, circular, or elliptical, preferably, the upper surface is rectangular.

[0051] Further, a hydraulic rod 104 is provided on the upper surface of the mounting base 101. The hydraulic rod 104 is in a columnar structure and is fixedly installed on the upper surface for supporting the connecting seat 102. Preferably, the hydraulic rod 104 is fixedly installed at each corner of the rectangular upper surface. The fixing method can be screw fixing or welding fixing. Preferably, the upper surface of the mounting base 101 and the hydraulic rod 104 are welded and fixed. One or more hydraulic rods 104 are provided. For example, there are 2, 3, 4, 5, or 6 hydraulic rods 104. Preferably, 4 hydraulic rods 104 are provided. A receiving space is formed between the multiple hydraulic rods 104. The lower roller 5 is arranged in this receiving space, and the driving mechanism is arranged in this receiving space, which is beautiful and saves space. A connecting seat 102 is fixedly installed above the hydraulic rod 104. The hydraulic rod 104 can drive the connecting seat 102 to move up and down.

[0052] The connecting seat 102 is in a frame structure for installing the upper roller 4. The upper roller 4 is fixedly installed in the frame structure. The cross-sectional shape of the end of the frame structure is L-shaped for facilitating the fixing of the hydraulic rod 104. The connecting seat 102 is fixedly connected to the mounting base 101 through the hydraulic rod 104. The L-shaped end of the connecting seat 102 is fixedly connected to the hydraulic rod 104. The fixing connection method is screw fixing or welding fixing. Preferably, the L-shaped end and the hydraulic rod 104 are welded and fixed. Convex plates are provided upward at both ends of the frame structure for carrying or fixing the straightening roller assembly. Preferably, the cross-section of the frame structure is rectangular. Rotation holes are provided along the direction of each short side 1021 of the rectangle for installing the upper roller 4. The rotation holes are symmetrically arranged on both sides of the midpoint connection line of the two long sides 1022 of the rectangle. Both ends of the upper roller 4 are arranged in the rotation holes. The number of rotation holes in the direction of each short side 1021 is set to be one or more, which is the same as the number of the upper rollers 4. For example, there are 2, 3, 4, 5, or 6 rotation holes. Preferably, the number of rotation holes in the direction of each short side 1021 is 3. During use, the steel moves in and out along the short side 1021 direction of the frame structure. The rotation holes of the connecting seat 102 are installed with the upper rollers 4, and the steel is stretched and straightened through the cooperation of the upper rollers 4 and the lower rollers 5.

[0053] Further, the locking member 301 has a conical structure. In the present utility model, the locking member 301 includes a turning knob. On one side of the turning knob, a mating frustum is provided. On the end face of the mating frustum, a threaded post is provided. The threaded post is used to rotate to the end of the lower roller. The mating frustum is disposed opposite to the annular protrusion in the radial direction (the radial direction of the lower roller). The fastener includes an outer contact surface (the outer contact surface is a curved surface structure for contacting the inner ring of the bearing) and a mating portion provided inside the outer contact surface. The end face of the mating portion is an inclined surface structure and contacts the outer side surface of the mating frustum. The locking member 301 can move axially when rotating on the lower roller. When the mating frustum contacts the mating portion, the axial movement can be converted into the radial movement of the fastener. The outer contact surface expands and presses against the inner ring of the bearing to fix the lower roller, or the outer contact surface contracts and separates from the inner ring of the bearing to disassemble the lower roller. The cooperation between the locking member 301 and the fastener 302 can convert the horizontal movement into the expansion or contraction of the outer contact surface. When the locking member 301 is tightened or loosened, the conical structure moves horizontally inward or outward, driving the fastener 302 to expand outward or contract inward, locking or unlocking the connection relationship between the lower roller 5 and the bearing.

[0054] Further, a handle (i.e., the above-mentioned turning knob) is provided on the outer side of the locking member 301 for facilitating the installation and disassembly of the locking member 301, the fastener 302, and the lower roller 5. The locking member 301 and the handle are engaged. In a specific embodiment, when the handle is tightened, the locking member 301 is tightened, and the conical structure (the above-mentioned mating frustum) moves horizontally inward. The fastener 302 expands outward and is in interference fit with the inner ring of the bearing for fixed connection, thereby fixing the lower roller 5 and the bearing. When the handle is loosened, the locking member 301 is loosened, and the conical structure moves horizontally outward. The fastener 302 contracts inward and separates from the inner ring of the bearing, thereby removing the lower roller 5. Of course, in another specific embodiment, when the handle is tightened, the locking member 301 is tightened, and the conical structure moves horizontally outward. The fastener 302 expands outward and is in interference fit with the inner ring of the bearing for fixed connection, thereby fixing the locking member 301 and the lower roller 5. When the handle is loosened, the locking member 301 is loosened, and the conical structure moves horizontally inward. The fastener 302 contracts inward and separates from the inner ring of the bearing, thereby removing the locking member 301 and the lower roller 5. Generally speaking, when the handle is tightened, the locking member 301, the fastener 302, the lower roller 5, and the bearing are fixed. When the handle is loosened, the locking member 301, the fastener 302, the lower roller 5, and the bearing are disassembled.

[0055] Further, as Figure 3As shown, the driving mechanism is arranged below the connecting seat 102. The driving mechanism includes a driving member 201, which is used to provide power for the lower roller 5. A driving motor is arranged inside the driving member 201. The driving motor and the lower roller 5 are detachably connected. Specifically, the driving motor and the lower roller 5 can be in interference fit, or the driving motor and the lower roller 5 are in meshing connection (through the meshing of a gear assembly). The driving motor is used to provide power for the lower roller 5. The driving motor is installed below the connecting seat 102. The mounting bracket 103 is located at one end of the lower roller 5, and the driving motor is located at the other end of the lower roller 5. Specifically, the mounting bracket 103 is located at one end of the lower roller 5 along the short side 1021 direction of the frame structure. The driving motor is located at the other end of the lower roller 5 along the short side 1021 direction of the frame structure. The driving motor is provided with an output port along the short side 1021 direction of the frame structure, which is used to install the lower roller 5 and transmit torque to the lower roller 5. The driving mechanism can also be in other structural forms, and any power device capable of driving the lower roller 5 to rotate can be applied to the present invention.

[0056] The driving mechanism is an integral structure, and the acting power device is applied to the present invention. A power output port is arranged on the driving mechanism. There are multiple power output ports, and the number of their settings corresponds to the number of settings of the lower roller 5. In a specific embodiment of the present invention, a rotating shaft (the rotating shaft is a component structure of the lower roller 5 and is coaxially arranged with the lower roller 5) is arranged at the other end of the lower roller 5, and is detachably fixed to the output port of the driving motor for transmitting torque. That is to say, the rotating shaft at the other end of the lower roller 5 is inserted into the output port of the driving mechanism to detachably connect the lower roller 5 and the driving mechanism. Specifically, the rotating shaft and the output port can be in interference fit to realize the driving motor transmitting torque (that is, power) to the lower roller 5; the rotating shaft is in a convex column shape. Preferably, the convex rotating shaft is cylindrical.

[0057] The number of output ports can be 1 or more. The number of output ports is the same as the number of lower rollers 5. Multiple output ports, such as 2, 3, 4, 5, 6. Preferably, the number of output ports is 4; the other end (i.e., the rotating shaft) of the lower roller 5 is detachably and fixedly installed in the output port.

[0058] The mounting bracket 103 is provided with through holes in the direction of the short side 1021 of the frame structure. Bearings are arranged in the through holes for mounting one end of the lower roller 5. The bearings in the through holes of the mounting bracket 103 and one end of the lower roller 5 are detachably fixed. That is to say, one end of the lower roller 5 is mounted in the bearing of the through hole of the mounting bracket 103, and the other end is mounted in the output port of the driving member 201. The mounting of both ends of the lower roller 5 is detachable. During use, the driving motor drives the lower roller 5 to rotate. When the locking member 301 is tightened or loosened, the conical structure moves horizontally inward or outward, driving the fastener 302 to expand outward or contract inward, locking or unlocking the connection relationship between the lower roller 5 and the bearing.

[0059] Further, the lower roller 5 and the locking member 301 are fixed by a screwing mechanism. The screwing mechanism is such that one of the lower roller 5 and the locking member 301 is provided with a threaded hole and the other is provided with a stud. That is to say, the lower roller 5 and the locking member 301 are detachably fixed by screwing. In a specific embodiment, one end of the locking member 301 is provided with a stud, and correspondingly, a threaded hole is provided at one end of the lower roller 5. The locking member 301 and the lower roller 5 are detachably fixed by screwing through the cooperation of the stud and the threaded hole; in another specific embodiment, one end of the locking member 301 is provided with a threaded hole, and correspondingly, a stud is provided at one end of the lower roller 5. The locking member 301 and the lower roller 5 are detachably fixed by screwing through the cooperation of the stud and the threaded hole.

[0060] In a specific embodiment, the handle is detachably fixedly connected to the screwing mechanism. When the handle is tightened, the locking member 301, the fastener 302, the lower roller 5 and the bearing are fixedly installed through the screwing mechanism and the conical structure. When the handle is loosened, the screwing mechanism, the conical structure, the locking member 301, the fastener 302, the lower roller 5 and the bearing are removed. This facilitates the replacement of the lower roller 5.

[0061] Further, the fastener 302 is arranged in the circumferential direction of the locking member 301. The number of the fasteners 302 is set to be one or more, and multiple ones are, for example, 2, 3, 4, 5, 6. Preferably, the number of the fasteners 302 is 3. The extending manner of the fastener 302 is consistent with the circumferential direction of the locking member 301. Multiple fasteners 302 are evenly distributed along the circumferential manner of the locking member 301. A columnar protrusion is arranged inside the fastener 302 for detachably connecting the fastener 302 and the lower roller 5. Specifically, the columnar protrusion of the fastener 302 is inserted into the sliding hole of the lower roller 5 to detachably fix the fastener 302 and the lower roller 5.

[0062] An arc-shaped groove is provided inside the columnar protrusion for cooperation with the conical structure. Specifically, the arc-shaped groove meshes with the locking member 301; the arc-shaped groove contacts the conical structure of the locking member 301, and the arc-shaped groove is sleeved outside the conical structure, thereby converting the horizontal movement of the conical structure into the outward expansion or inward contraction of the fastener 302 to lock or unlock the connection relationship between the lower roller 5 and the bearing. In a specific embodiment, the arc-shaped grooves of the 3 fasteners 302 are sleeved outside the conical structure of the locking member 301.

[0063] In a specific embodiment, when installing the lower roller 5, the conical structure moves horizontally inward, and the fastener 302 expands outward and has an interference fit with the inner ring of the bearing. The 3 fasteners 302 will fix the lower roller 5 and the bearing of the mounting bracket 103; when removing the lower roller 5, the conical structure moves horizontally outward, and the fastener 302 contracts inward. The fastener 302 will loosen the lower roller 5 and the bearing of the mounting bracket 103, and then the lower roller 5 can be removed.
