Description

Technical Field

[0001] This utility model relates to the field of forging sawing technology, specifically a forging sawing device with a transition conveying mechanism. Background Technology

[0002] Forging sawing equipment with transition conveyor mechanism is a composite equipment that integrates sawing processing and automated conveying system. It is specially used for cutting metal materials, especially high temperature forging billets. It can establish seamless connection between different processes and realize full-process automation from billet input to finished product output. It accurately conveys high temperature forging billets from heating equipment (such as medium frequency furnace) to sawing position to complete high-precision sawing processing. The transition conveyor mechanism is an intelligent conveying system that connects the upstream equipment (heating furnace) and the sawing host. It solves the problems of height difference, speed matching and precise positioning between different equipment. High-temperature billets (such as heated round steel) are output from the heating equipment and enter the connecting platform of the transition mechanism through the first conveyor chain. After the billet arrives at the transition platform, the positioning sensor detects its position, and the servo system controls the conveyor chain or roller to move precisely so that the billet is aligned with the sawing position. The pushing mechanism pushes the billet smoothly to the clamping device of the sawing host. When switching between blanks of different diameters or cross-sectional shapes during production, the adjustment accuracy of the guide limit end, V-shaped guide groove and adjustable baffle is limited, and it is impossible to achieve a complete fit according to the blank specifications. Large-diameter blanks are prone to instability and shaking during transportation due to insufficient support contact area, while small-diameter blanks are difficult to be precisely constrained due to excessive limit gaps and thus deviate. Both of these result in the blanks not being accurately aligned with subsequent workstations. Blanks of different specifications are prone to point contact when limited, directly causing blank positioning deviation. Therefore, a forging sawing device with a transition conveying mechanism is proposed to address the above problems. Utility Model Content

[0003] The purpose of this invention is to provide a forging sawing device with a transition conveying mechanism to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A forging sawing device with a transition conveying mechanism includes a sawing device, a transition conveying mechanism fixed to one side of the sawing device, a clamping device and a sawing host fixed to the upper end of the sawing device; the clamping device includes an electric telescopic rod, a control rod fixed to the telescopic end of the electric telescopic rod, connecting rods fixed to both ends of the control rod, a pulley fixed to one end of the connecting rod, the outer side of the pulley being in close contact with the inner side of a limiting band, and one end of the limiting band passing through the inner side of a limiting shell; the limiting band includes a rubber belt, sliders fixed to the upper and lower sides of the rubber belt, friction protrusions fixed to the end of the rubber belt located inside the limiting shell, the limiting shell including a housing, a through hole opened at the center of the housing, and a limiting groove opened on the inner side of the housing.

[0005] As a further optimization of this utility model, the electric telescopic rod is fixed to the upper end of the sawing equipment, the telescopic direction of the electric telescopic rod is parallel to the conveying direction of the transition conveying mechanism, and the telescopic end of the electric telescopic rod is fixedly connected to the middle position of the control rod.

[0006] As a further optimization of this utility model, the number of pulleys is four, two pulleys are symmetrically distributed with the central axis of the control rod as the axis of symmetry, the diameters of the two pulleys are exactly the same, the axes of the two pulleys are on the same horizontal straight line, and the corresponding two pulleys are staggered and intersecting.

[0007] As a further optimization of this utility model, the number of limiting bands is four, and each limiting band is set on the outside of each pulley. The corresponding two limiting bands are staggered and cross each other, and one end of each limiting band passes through the inside of the limiting groove.

[0008] As a further optimization of this utility model, the sliders are all embedded in the inner side of the limiting groove, the sliders are symmetrically arranged with the central axis of the rubber strip as the axis of symmetry, and the outer side of the slider is slidably connected to the inner side of the limiting groove.

[0009] As a further optimization of this utility model, the perforation is rectangular in shape, the length direction of the perforation is consistent with the length direction of the shell, and the width of the perforation is adapted to the width of the limiting band.

[0010] As a further optimization of this utility model, the friction protrusions are multiple, and the multiple friction protrusions are distributed in two rows along the width direction of the rubber belt. The friction protrusions in each row are arranged at equal intervals along the length direction of the rubber belt, and the friction protrusions all protrude from the arc-shaped surface of the rubber belt.

[0011] Compared with the prior art, the beneficial effects of this utility model are: In this invention, the electric telescopic rod drives the control rod in the middle, and the symmetrically distributed pulleys ensure that the tension at both ends is balanced, so that the four limiting bands tighten synchronously. This adapts to blanks of different specifications and cross-sections. The trajectory constraint prevents the limiting bands from jamming or deviating, ensuring smooth clamping action. The two rows of equidistant friction protrusions on the surface of the rubber band increase the friction when the limiting bands are in contact with the blank, achieving stable output of clamping force and ensuring stable positioning.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0016] Please see Figures 1-6 This utility model provides a technical solution: A forging sawing device with a transition conveying mechanism includes a sawing device 1, a transition conveying mechanism 2 fixed on one side of the sawing device 1, a clamping device 3 and a sawing host 4 fixed on the upper end of the sawing device 1; the clamping device 3 includes an electric telescopic rod 31, a control rod 32 fixed at the telescopic end of the electric telescopic rod 31, connecting rods 33 fixedly connected to both ends of the control rod 32, a pulley 34 fixed at one end of the connecting rod 33, the outer side of the pulley 34 closely adhering to the inner side of the limiting band 35, and one end of the limiting band 35 passing through the inner side of the limiting shell 36; the limiting band 35 includes a rubber band 351, sliders 352 fixed on the upper and lower sides of the rubber band 351, a friction protrusion 353 fixed at one end of the rubber band 351 located inside the limiting shell 36, the limiting shell 36 includes a shell 361, a through hole 362 opened at the center of the shell 361, and a limiting groove 363 opened on the inner side of the shell 361.

[0017] It should be noted that: the electric telescopic rod 31 is fixed on the upper end of the sawing equipment 1, the telescopic direction of the electric telescopic rod 31 is parallel to the conveying direction of the transition conveying mechanism 2, the telescopic end of the electric telescopic rod 31 is fixedly connected to the middle position of the control rod 32, there are four pulleys 34, two pulleys 34 are symmetrically distributed about the central axis of the control rod 32, the diameter of the two pulleys 34 is exactly the same, the axis of the two pulleys 34 is on the same horizontal straight line, and the corresponding two pulleys 34 are staggered and cross-set; Specifically: There are four limiting bands 35, all of which are set on the outside of each pulley 34. The corresponding two limiting bands 35 are staggered and cross each other. One end of the limiting band 35 passes through the inside of the limiting groove 363. The four limiting bands 35 correspond one-to-one with the four pulleys 34, which can realize multi-point clamping of the billet, making the clamping force distribution more uniform. It effectively avoids deformation caused by excessive local force on the billet when clamped by a single or two limiting bands 35. One end of the limiting band 35 passes through the inside of the limiting groove 363, so that the limiting groove 363 can accurately constrain the movement trajectory of the limiting band 35, preventing the limiting band 35 from deviating or jamming during tightening or loosening, and ensuring the smoothness and accuracy of the clamping action. Furthermore: The electric telescopic rod 31 is fixed to the upper end of the sawing equipment 1, and can provide reliable support for the clamping action with the help of the stable structure of the equipment body, so as to avoid the electric telescopic rod 31 shaking due to unstable installation during operation and affecting the clamping accuracy. The four pulleys 34 can correspond to the four limiting bands 35, so that the blank is subjected to multi-directional force when clamping. Compared with fewer pulleys 34, the clamping stability can be significantly improved. The pulleys 34 are staggered and cross-set, which can make the limiting bands 35 form a ring-like tightening trend, making the limiting bands 35 fit the blank surface more closely and improving the clamping reliability. As a further implementation of this solution, the sliders 352 are all embedded in the inner side of the limiting groove 363. The sliders 352 are symmetrically arranged with the central axis of the rubber band 351 as the axis of symmetry. The outer side of the sliders 352 is slidably connected to the inner side of the limiting groove 363. The through hole 362 is rectangular in shape. The length direction of the through hole 362 is consistent with the length direction of the housing 361. The width of the through hole 362 is adapted to the width of the limiting band 35. Specifically: There are multiple friction protrusions 353, which are distributed in two rows along the width direction of the rubber belt 351. Each row of friction protrusions 353 is evenly spaced along the length direction of the rubber belt 351. All friction protrusions 353 protrude from the arc-shaped surface of the rubber belt 351. The setting of multiple friction protrusions 353 can significantly increase the friction between the limiting band 35 and the surface of the blank. Even if there is oxide scale on the surface of the blank in a high-temperature environment, the interlocking effect of the protrusions can prevent the blank from slipping during the sawing process, ensuring sawing accuracy. The two rows can adapt to blanks of different widths, improving clamping applicability. The evenly spaced friction protrusions 353 in each row and protruding from the arc-shaped surface of the rubber belt 351 can make the surface of the blank more evenly stressed, avoiding excessive local stress that could damage the blank. The protrusions on the arc-shaped surface can also better fit the surface of the blank, improving the friction effect. Furthermore: the slider 352 is embedded inside the limiting groove 363, which can provide a clear guiding path for the movement of the limiting band 35, completely solving the problem that the limiting band 35 is prone to deviating from the preset trajectory when it is tightened under force, ensuring that the limiting band 35 always accurately fits the blank to be clamped position. The through hole 362 is rectangular in shape and its length direction is consistent with the shell 361, which can provide sufficient space for the entry and exit of the limiting band 35, adapt to the extension and retraction stroke of the limiting band 35 during the clamping process, and avoid the limiting band 35 from getting stuck due to insufficient space in the through hole 362; Work process: The forging billet to be processed is conveyed at a constant speed by the transition conveyor 2. When the front end of the forging billet reaches the preset position of the sawing station of the sawing equipment 1, the transition conveyor 2 automatically stops running to ensure that the axis of the forging billet is perpendicular to the sawing trajectory of the sawing host 4, thus completing the initial positioning of the billet. The control system of the sawing equipment 1 issues a clamping command, and the clamping device 3 fixed to the upper end of the sawing equipment 1 starts to operate. After receiving the signal, the electric telescopic rod 31 begins to retract, and its telescopic end drives the control rod 32 to move. The pulleys 34 at both ends of the control rod 32 move synchronously with the control rod 32. Since the pulleys 34 are in close contact with the inner side of the limiting band 35, the moving pulleys 34 generate tension on the limiting band 35, causing the limiting band 35 to slide along the limiting groove 363 on the inner side of the limiting shell 36. When the limiting band 35 moves, the sliders 352 fixed on the upper and lower sides of its rubber band 351 are embedded in the inner side of the limiting groove 363 and slide along with it. The cooperation between the sliders 352 and the limiting groove 363 limits the deviation of the limiting band 35, ensuring that the limiting band 35 is always tightened along the preset trajectory. The two sets of pulleys 34 arranged opposite to each other are misaligned with the limiting band 35. The cross-pulling causes the limiting band 35 to form a wrapping tightening tendency on the billet. As the electric telescopic rod 31 continues to contract, the limiting band 35 gradually adheres to the surface of the forging billet. The friction protrusion 353 at one end of the rubber band 351 located inside the limiting shell 36 contacts the surface of the forging billet and generates friction. When the electric telescopic rod 31 contracts to the preset stroke, the friction protrusion 353 tightly adheres to the billet, and the limiting band 35 forms a stable clamping force on the billet, completing the clamping and fixing of the billet. The clamping device 3 maintains the clamping state, and the control system sends a sawing command to the sawing host 4. The sawing host 4 starts and feeds along the direction perpendicular to the axis of the billet to perform sawing processing on the clamped and fixed forging billet. During the sawing process, the electric telescopic rod 31 of the clamping device 3 remains in the contracted state, and the limiting band 35 continuously provides clamping force to prevent the billet from shaking. After the sawing host 4 completes sawing, it returns to the initial position. The control system issues a release command, the electric telescopic rod 31 begins to extend, driving the control rod 32 to move in the opposite direction. The pulley 34 then pushes the limiting band 35 back along the limiting groove 363. The limiting band 35 separates from the surface of the blank, the friction protrusion 353 no longer contacts the blank, and the limiting band 35 returns to the relaxed state.
