Description

Technical Field

[0001] The present invention relates to the technical field of metallurgical machinery, and particularly to a double-buffer baffle. Background Art

[0002] The baffle is an essential device for the bar production line. Whether it is for positioning the rolled piece during transportation or preventing the rolled piece from detaching from the conveying equipment, the baffle device will be applied. Fixed baffles are installed at both ends of the conveying roller table when the bars in the bar production line are bundled and collected. One is to improve the flatness of the ends of the bundled rolled pieces by aligning the heads; the other is to fix the wire for passing steel to ensure that the ends of each bundle of rolled pieces are consistent. The existing fixed baffles basically use a movable plate with counterbored holes processed on it and are connected to the corresponding fixed plate of the fixed base through countersunk bolts. Rubber sheets, dampers or springs and other buffer components are installed between the corresponding fixed plate of the fixed base and the movable plate to buffer. This kind of fixed baffle has many deficiencies, which increase the production and maintenance costs and also increase the workload and difficulty of equipment maintenance. First of all, the sum of the weights of the baffle and the counterweight plate, when added to the force generated by the non-linear vibration generated when the steel impacts the baffle, always causes the fixed bolts to break or the thread of the fixed bolts to be damaged, resulting in the dropping of the counterweight plate and the baffle. Secondly, the baffle is in direct contact with the end face of the bar during operation and bears the impact force and vibration of the bar first. Therefore, the connecting bolts often break or the internal thread of the counterweight plate is damaged. In addition, the gasket on the threaded section of the guide rod slides in the threaded section under the action of the impact force repeatedly, resulting in damage to the external thread of the threaded section and affecting the adjustment of the buffer force of the disc spring. Finally, when installing the guide rod during maintenance, since the two guide rods are always stuck by the disc spring when entering the holes of the fixed frame body, it is time-consuming and laborious to align them.

[0003] In view of this, the present invention is specifically proposed. Summary of the Invention

[0004] The purpose of the present invention is to provide a double-buffer baffle to solve the problems that the existing baffle structure is unreasonable and the buffer force provided is insufficient, resulting in the failure of the buffer device and the inability to play a buffering role.

[0005] To solve the above technical problems, the present invention provides a double-buffer baffle, including a baffle, a solid kinetic energy ball, a plurality of flange guide rods, a fixed frame body, and a buffer device, wherein:

[0006] The buffer device is arranged in the fixed frame body. One end of each flange guide rod is fixedly connected to the baffle, and the other end passes through the buffer device and is fixedly connected to the fixed frame body;

[0007] Through grooves matching the solid kinetic energy ball are respectively radially formed in the flange guide rods, and the solid kinetic energy ball is placed in the through grooves and moves left and right to counteract the impact force generated when the bar impacts the baffle.

[0008] Furthermore, the fixed frame body includes a bottom plate, and two parallel support plates are vertically fixed on the bottom plate. A first fixing plate and a second fixing plate which are perpendicular to the bottom plate and parallel to each other are arranged between the two support plates. The first fixing plate, the second fixing plate, the bottom plate and the two support plates enclose an accommodation space for placing the buffer device.

[0009] Furthermore, the buffer device is a plurality of disc spring groups placed in parallel, and the disc spring groups are sleeved on the flange guide rods.

[0010] Furthermore, a plurality of first through holes and second through holes are respectively formed on the first fixing plate and the second fixing plate; the centers of the first through holes, the second through holes and the disc spring groups are coaxial; the other ends of the flange guide rods respectively pass through the first through holes, the disc spring groups and the second through holes in sequence; external threads are formed at the other ends of the flange guide rods, and flange nuts are matched with the external threads to fix the other ends of the flange guide rods on the second fixing plate.

[0011] Furthermore, an anti-loosening connecting plate is further included, and a plurality of small holes are evenly formed on the anti-loosening connecting plate for fixing the anti-loosening connecting plate and the flange nut through bolts.

[0012] Furthermore, an arc-shaped supporting plate is arranged at the bottom of the disc spring group, and the arc-shaped supporting plate is fixed to the bottom plate through a bracket.

[0013] Furthermore, a circular groove is formed on one side of the baffle, and a cylindrical protrusion matching the circular groove is arranged at one end of the guiding connecting rod.

[0014] Furthermore, a chamfer is arranged on the cylindrical protrusion so as to be closely attached to each other when matching with the circular groove.

[0015] Furthermore, a plurality of countersunk through holes are evenly formed on the baffle for fixing the flange guide rod and the baffle through bolts.

[0016] Furthermore, a rubber damping body is arranged at one end of the disc spring group close to the second fixing plate.

[0017] Furthermore, the rubber damping body is made of nitrile rubber material.

[0018] Furthermore, the number of the flange guide rods is two.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] 1. The double-buffer baffle of the present invention can counteract the kinetic energy generated when the bar impacts the baffle by placing a solid kinetic energy ball inside the flange guide rod, reducing the impact and vibration on the system. While improving the overall working performance, it also protects each component of the system.

[0021] 2. By setting a rubber damper at one end of the disc spring group, the combined action of the rubber damper and the disc spring group enhances the buffering ability and also protects the disc spring group from premature failure.

[0022] 3. Through the clearance fit between the groove of the baffle and the protrusion of the flange guide rod, and at the same time, the flange guide rod and the counterbore through-hole on the baffle are fixed by bolts, it not only plays a positioning role but also reduces the weight of the baffle assembly, improving the service life of the equipment.

[0023] 4. By setting a lock prevention connecting plate, it is more convenient to adjust the pre-tightening force of the buffer device and protects the external thread of the flange guide rod from damage.

[0024] 5. By setting an arc-shaped support plate at the bottom of the disc spring group, the phenomenon of jamming during the installation of the flange guide rod and the disc spring group is avoided. BRIEF DESCRIPTION OF THE DRAWINGS

Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the said features. In the description of the present invention, "a plurality of" means two or more unless otherwise specifically defined. In addition, the terms "mounted", "connected", and "coupled" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0046] Referring to Figure 1-7 As shown, a double buffer baffle proposed by the present invention includes a baffle 1, a solid kinetic energy ball 2, a plurality of flange guide rods 3, a solid frame 4, and a buffer device. Among them, the buffer device is arranged in the fixed frame 4. One end of each flange guide rod 3 is fixedly connected to the baffle 1, and the other end passes through the buffer device and is fixedly connected to the fixed frame 4; through grooves 31 matching the solid kinetic energy ball 2 are respectively formed in the radial direction of the flange guide rods 3, and the solid kinetic energy ball 2 is placed in the through grooves 31 and can move left and right to counteract the impact force generated when the bar impacts the baffle.

[0047] Specifically, as Figure 3 shown, the kinetic energy of the bar hitting the baffle 1 is E1, the buffer force generated by the overall baffle structure causes the solid kinetic energy ball 2 to generate a kinetic energy E2 and the flange guide rods 3 to generate a kinetic energy E3. E1 is greater than or equal to the sum of E2 and E3. However, due to the generation of E2, the kinetic energy generated when the bar impacts the baffle is advantageously reduced. Therefore, a part of it can be offset, reducing the impact on the system. Moreover, the movement of the solid kinetic energy ball 2 in the through groove 31 can also offset the non-linear force received by the overall baffle structure.

[0048] The fixed frame 4 includes a bottom plate 41, and two parallel support plates 42 are vertically fixed on the bottom plate 41. A first fixing plate 43 and a second fixing plate 44 perpendicular to the bottom plate 41 and parallel to each other are arranged between the two support plates 42. The first fixing plate 43, the second fixing plate 44, the bottom plate 41, and the two support plates 42 enclose an accommodation space, and the buffer device is placed in the accommodation space. The buffer device is preferably a plurality of disk spring groups 5 placed in parallel, and the disk spring groups 5 are sleeved on the flange guide rods 3.

[0049] Specifically, a number of first through holes 431 and second through holes 441 are provided on the first fixing plate 43 and the second fixing plate 44 respectively; the centers of the first through holes 431, the second through holes 441, and the disc spring group 5 are coaxial; the other ends of the flange guide rods 3 sequentially pass through the first through holes 431, the disc spring group 5, and the second through holes 441 respectively; external threads are also provided at the other ends of the flange guide rods 3, and after the flange nuts 6 are engaged with the external threads, the other ends of the flange guide rods 3 and the second fixing plate 44 are fixed. On the basis of the above solution, a lock washer connecting plate 7 is further included, and a number of small holes are evenly provided on the lock washer connecting plate 7 for fixing the lock washer connecting plate 7 and the flange nut 6 through bolts. Such a setting can prevent the flange nut 6 from loosening and shifting, and at the same time avoid the situation where the external thread section of the flange guide rod 3 cannot be adjusted due to wear caused by loosening displacement.

[0050] A circular groove is provided on one side of the baffle 1, and a cylindrical protrusion matching the circular groove is provided at one end of the flange guide rod 3; the circular groove and the cylindrical protrusion are in clearance fit; in order to make the two contact surfaces of the circular groove and the cylindrical protrusion closely fit during installation, a chamfer is also provided on the cylindrical protrusion, as Figure 4-5 shown. At the same time, a number of countersunk through holes 11 are evenly provided on the baffle 1 for fixing the flange guide rod 3 and the baffle 1 through bolts. Through the above fixed connection method, not only the positioning function is achieved, but also the weight of the baffle assembly is reduced, and the service life of the equipment is improved.

[0051] In addition, the number of the flange guide rods 3 provided can be adjusted according to actual needs. In this embodiment, the number of the flange guide rods 3 is 2, and 2 can meet the on-site requirements of most bar production lines.

[0052] On the basis of the above solution, an arc-shaped support plate 8 is further provided at the bottom of the disc spring group 5, and the arc-shaped support plate 8 is fixed to the bottom plate 41 through a bracket, as Figure 7 shown. When installing the flange guide rod 3, since the guide flange rod 3 is always stuck by the disc spring group 5 when centering and entering the hole of the fixed bracket 4, after the arc-shaped support plate 8 is provided, the phenomenon of jamming between the flange guide rod 3 and the disc spring group 5 can be avoided during installation.

[0053] On the basis of the above solution, a rubber damper 9 is further provided at one end of the disc spring group 5 close to the second fixing plate 44. After the rubber damper 9 and the disc spring group 5 act together, the buffering ability is enhanced, and the disc spring group 5 is also protected, avoiding the premature failure of the disc spring group. The material selection of the rubber damper 9 includes but is not limited to nitrile rubber, and any elastic material that can meet the corresponding requirements can be used.

[0054] The solid kinetic energy ball in the flange guide rod of the double buffer baffle of the present invention can offset the impact kinetic energy of the system, reduce the weight of the baffle structure, and add a double buffer structure composed of a rubber damper and a disc spring group to improve the buffering capacity. The structure of the fixed frame is transformed to make it more convenient and labor-saving to install the flange guide rod and the disc spring group. All the transformations make the whole baffle assembly more compact, improve the overall working performance, and also protect all the components of the system.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
