Description
Technical Field
[0001] This utility model relates to the field of metal material processing machinery and equipment, and in particular to a shearing machine for shearing round steel. Background Technology
[0002] Round steel, a common metal profile, is widely used in construction, manufacturing, and other industries, and often needs to be cut to specific lengths. Currently, hydraulic shearing machines are commonly used for shearing round steel. However, during the shearing process, the round steel is prone to axial movement or torsion due to the enormous shearing force, resulting in quality problems such as oblique cuts, flattening, and excessive burrs on the cut surface, making it difficult to meet the requirements of high-precision machining. Moreover, the impact vibration during shearing can easily lead to unstable clamping of the equipment, affecting tool life and product consistency. Therefore, there is an urgent need for a shearing device that can stably clamp round steel and ensure perpendicular and high-quality cuts. Utility Model Content
[0003] The purpose of this invention is to provide a round steel shearing machine to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a round steel shearing machine, comprising a frame, a clamping mechanism mounted on the frame for clamping round steel, a driving mechanism, and a shearing mechanism;
[0005] The clamping mechanism includes a first clamping mechanism and a second clamping mechanism arranged sequentially along the axial direction of the round steel. The first clamping mechanism and the second clamping mechanism are respectively used to clamp the front end and the rear end of the round steel to be cut.
[0006] The shearing mechanism is disposed between the first clamping mechanism and the second clamping mechanism, and the connection position between the first clamping mechanism and the second clamping mechanism forms the shearing station of the shearing mechanism;
[0007] The driving mechanism drives the first clamping mechanism and the second clamping mechanism to clamp the round steel simultaneously, and drives the shearing mechanism to perform a shearing action on the round steel, so that the axial direction of the round steel remains perpendicular to the cutting direction during the shearing process.
[0008] Furthermore, it also includes an auxiliary pressure mechanism, which includes a first auxiliary pressure mechanism and a second auxiliary pressure mechanism. The first auxiliary pressure mechanism is disposed between the frame and the first clamping mechanism, and the second auxiliary pressure mechanism is disposed between the second clamping mechanism and the frame.
[0009] Furthermore, the first auxiliary pressure mechanism and the second auxiliary pressure mechanism are arranged in a staggered manner in a plane perpendicular to the axis of the round steel.
[0010] Furthermore, the first auxiliary pressure mechanism and the second auxiliary pressure mechanism include an elastic element and a guide rod. The guide rod is vertically fixed to the frame and the first clamping mechanism or the second clamping mechanism. The two ends of the elastic element abut against the frame and the corresponding clamping mechanism, respectively.
[0011] Furthermore, both the first clamping mechanism and the second clamping mechanism include a fixed clamping block and a movable clamping block, and the relative clamping surfaces of the fixed clamping block and the movable clamping block are provided with arc-shaped grooves adapted to the outer circumference of the round steel.
[0012] Furthermore, the drive mechanism includes a hydraulic cylinder.
[0013] Furthermore, the shearing mechanism includes an upper shear blade and a lower shear blade. The cutting edges of both the upper and lower shear blades are provided with notches that are adapted to the outer circumference of the round steel. The lower shear blade is fixed on the frame, and the upper shear blade is connected to the output end of the drive mechanism.
[0014] Furthermore, the upper and lower shear blades are arranged in a staggered manner.
[0015] Furthermore, the frame is equipped with an adjustment component for adjusting the misalignment distance between the upper and lower shear blades.
[0016] Furthermore, the adjustment component includes a dovetail groove disposed on the frame and a slider integrally formed with the mounting base of the upper shear blade. The mounting base is slidably disposed in the dovetail groove and locked onto the frame.
[0017] Compared with the prior art, the beneficial effects of this utility model are:
[0018] 1. The first and second clamping mechanisms clamp the steel simultaneously before and after the shearing point, and combined with the upper and lower staggered auxiliary pressure mechanism, to prevent the axial movement and torsional deformation of the round steel during the shearing process, ensuring that the cut end face is perpendicular to the axis of the round steel, improving the flatness of the cut surface and the quality of the cross-section.
[0019] 2. The auxiliary pressure mechanism uses springs and guide rods to provide continuous and stable elastic clamping force, which effectively buffers the shearing impact and enables the clamping mechanism to maintain a reliable clamping state throughout the shearing process.

Detailed Implementation
[0024] 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.
[0025] like Figures 1-2 As shown, this embodiment provides a round steel shearing machine, including a frame 1, a clamping mechanism for clamping round steel on the frame 1, a driving mechanism, a shearing mechanism 4, and an auxiliary pressing mechanism;
[0026] The frame 1 provides support for the entire equipment, and the drive mechanism adopts a hydraulic cylinder 21, which is fixed to the upper part of the frame 1;
[0027] The clamping mechanism includes a first clamping mechanism 1 and a second clamping mechanism 2 arranged side by side along the axial direction of the round steel 100. In this embodiment, the first clamping mechanism 1 is located on the left side and is used to clamp the front end of the round steel 100 to be cut, and the second clamping mechanism 2 is located on the right side and is used to clamp the rear end of the round steel 100 to be cut. Both the first clamping mechanism 1 and the second clamping mechanism 2 include a fixed clamping block 33 and a movable clamping block 34. The fixed clamping block 33 is fixed on the frame 1, and the movable clamping block 34 is driven by a hydraulic cylinder. The relative clamping surfaces of the fixed clamping block 33 and the movable clamping block 34 are provided with arc-shaped grooves 35 that are adapted to the outer circumference of the round steel 100 to provide surface contact. In this way, the first clamping mechanism 1 and the second clamping mechanism 2 clamp the entire round steel through the arc-shaped grooves 35 opened on their clamping surfaces, and the clamping is stable.
[0028] To ensure the reliability of clamping and absorb vibration, a first auxiliary pressure mechanism 51 is provided between the top plate of the frame 1 and the first clamping mechanism 1, and a second auxiliary pressure mechanism 52 is provided between the second clamping mechanism 2 and the base of the frame 1. Both the first auxiliary pressure mechanism 51 and the second auxiliary pressure mechanism 52 include an elastic element 53 and a guide rod 54. The guide rod 54 of the first auxiliary pressure mechanism 51 is vertically fixed to the frame 1 and the first clamping mechanism 1, with its upper end fixed to the crossbeam 22 connected to the output end of the hydraulic cylinder 21, and its lower end abutting against the fixed clamping block 33 of the first clamping mechanism 1. The two ends of the elastic element 53 of the first auxiliary pressure mechanism 51 respectively abut against... The crossbeam 22 connected to the output end of the hydraulic cylinder 21 and the upper surface of the fixed clamping block 33 of the first clamping mechanism 1 are connected. The guide rod 54 of the second auxiliary pressing mechanism 52 is vertically fixed to the frame 1 and the second clamping mechanism 1. The upper end abuts against the top plate of the frame 1 and the lower end abuts against the fixed clamping block 33 of the second clamping mechanism 2. The two ends of the elastic element 54 of the second auxiliary pressing mechanism 52 abut against the lower surface of the fixed clamping block 33 of the second clamping mechanism 2 and the base of the frame 1, respectively. The elastic element 54 is a spring. The first auxiliary pressing mechanism 51 and the second auxiliary pressing mechanism 52 are arranged in a staggered manner in a plane perpendicular to the axis of the round steel.
[0029] The shearing mechanism 4 is disposed between the first clamping mechanism 1 and the second clamping mechanism 2, and the connection position between the first clamping mechanism 1 and the second clamping mechanism 2 forms the shearing station of the shearing mechanism 4. The shearing mechanism 4 includes an upper shearing blade 41 and a lower shearing blade 42. The cutting edges of the upper shearing blade 41 and the lower shearing blade 42 are both provided with notches that are adapted to the outer circumference of the round steel, so as to better position and wrap the round steel 100 during shearing. The lower shearing blade 42 is fixed on the frame 1, and the upper shearing blade 41 is connected to the output end of the drive mechanism. In order to adjust the misalignment between the upper shear blade 41 and the lower shear blade 42, an adjustment component is provided on the frame 1. The adjustment component includes a dovetail groove machined on the frame 1, a slider 62 integrally formed with the mounting seat of the upper shear blade 41, and a locking bolt. In this embodiment, the mounting seat of the upper shear blade 41 can be integrally formed with the movable clamping block 33 of the second clamping mechanism 2. The slider 62 is embedded in the dovetail groove and can slide left and right along the dovetail groove. When it is necessary to adjust the gap, loosen the locking bolt, slide the slider 62 to the desired position, and then tighten the locking bolt to adjust.
[0030] The driving mechanism drives the movable clamping block 33 of the first clamping mechanism 1 and the second clamping mechanism 2 to move down simultaneously and cooperate with the fixed clamping block 34 to clamp the round steel. Under the action of the spring of the first auxiliary pressure mechanism 51, the round steel 100 is clamped, and at the same time, the upper shearing blade 41 moves downward. The lower shearing blade 42 works together to apply shearing force to the round steel. Under the action of the spring of the second auxiliary pressure mechanism 52, the round steel 100 continues to be clamped, so that the axial direction of the round steel 100 remains perpendicular to the cutting direction during the shearing process. When the shearing force reaches the yield limit of the round steel 100, the round steel 100 is cut off at the shearing position and pushed out.
[0031] The working process of this utility model is as follows:
[0032] Feeding: Feed the round steel bar 100 into the shearing machine so that the part to be sheared is between the upper shear blade 41 and the lower shear blade 42;
[0033] Synchronous action: Hydraulic cylinder 21 is activated, and the piston rod moves downward. At the same time, the piston rod drives the movable clamping block 34 of the first clamping mechanism 1 and the second clamping mechanism 2 to move downward, clamping the front and rear ends of the round steel 7 together with the fixed clamping block 33; at the same time, the pressure of the piston rod is transmitted through the springs of the first auxiliary pressure mechanism 51 and the second auxiliary pressure mechanism 52, continuing to press down, clamping the front and rear ends of the round steel 7 by the clamping force of the springs. During this process, the upper shear blade 41 moves downward.
[0034] Shearing: Under the action of the spring of the second auxiliary pressure mechanism 62, the upper shear blade 41 continues to descend and works together with the lower shear blade 42 to cut the round steel 100 and push it out. During the entire shearing process, since the entire round steel 100 is pressed, its axis always remains perpendicular to the shearing direction.
[0035] Reset: After shearing is completed, the piston rod of the hydraulic cylinder 21 retracts upward, the upper shear blade 41 is raised, and the first clamping mechanism 1 and the second clamping mechanism 2 release the round steel 100 under the action of the spring, and the equipment returns to the initial state, completing one work cycle.
[0036] This invention uses first and second clamping mechanisms to simultaneously clamp the round steel before and after the shearing point, combined with an upper and lower staggered auxiliary pressure mechanism, to prevent axial movement and torsional deformation of the round steel during the shearing process. This ensures that the cut end face is perpendicular to the axis of the round steel, improves the flatness of the cut surface, and results in good cross-sectional quality. The auxiliary pressure mechanism uses springs and guide rods to provide continuous and stable elastic clamping force, effectively buffering the shearing impact and ensuring that the clamping mechanism maintains a reliable clamping state throughout the shearing process.
[0037] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
