Description

Technical Field

[0001] The present application relates to the technical field of bar chamfering devices, and in particular to a cold-rolled bar chamfering device. Background Art

[0002] Cold rolled bar is a metal material processed by cold rolling process, which has excellent mechanical properties and surface quality.

[0003] The existing Chinese patent with publication number CN212470844U discloses a steel bar chamfering equipment, including an equipment box, two fixed plates are installed on the equipment box, and the fixed plates are respectively arranged at two ends of the equipment box, the equipment box is vertically provided with columns, and cross bars are vertically welded on the columns, the bottom of the cross bar is connected with a chamfering device through two hydraulic rods, and the chamfering device is arranged between the two fixed plates, the fixed plates are provided with clamping grooves, and clamping blocks are movably arranged on the tops of the clamping grooves, two positioning rollers are installed on the fixed plates, and a power roller is arranged between the positioning rollers, the two ends of the power roller are respectively rotatably connected to the two fixed plates, and the power roller is arranged on the surface of the equipment box, the chamfering device includes two mounting side plates, a chamfering roller and a servo motor, the two ends of the two mounting side plates are connected by a connecting rod, and the hydraulic rod is respectively fixedly connected to the connecting rod, and the two ends of the chamfering roller are rotatably connected between the mounting side plates.

[0004] The above-mentioned steel bar chamfering equipment can fix and clamp the steel bar that needs to be chamfered by arranging a fixed plate with a clamping function on the surface of the equipment box, and when clamping, the steel bar can be driven to rotate during the chamfering process through the power roller on the surface of the equipment box, so as to achieve 360-degree rotatable chamfering of the steel bar and increase the strength of the chamfering. When chamfering, the chamfering device is driven by the electromagnetic slide rail to move on the surface of the equipment box, and chamfers along the length direction of the steel bar, so that the chamfering is more comprehensive. This device is controlled by electricity and does not require manual chamfering, so it is safer and more efficient. However, the above-mentioned steel bar chamfering equipment still has some shortcomings, such as: in the process of the power roller driving the steel bar to achieve 360-degree rotation chamfering, the steel bar is easy to move along the length direction of the power roller, thereby affecting the chamfering effect of the chamfering roller on the steel bar, which needs to be improved. Utility Model Content

[0005] The purpose of the present application is to provide a cold-rolled bar chamfering device in order to improve the chamfering effect of the bar.

[0006] The present application provides a cold-rolled bar chamfering device that adopts the following technical solution:

[0007] The workbench comprises two support plates connected thereto, one of which is slidably connected to the workbench, the workbench is connected with a driving assembly for driving the support plate to slide toward or away from the other support plate, both support plates are slidably connected with at least two clamping plates, the support plates are connected with a linkage assembly for driving at least two clamping plates to slide toward or away from each other, one of the support plates is connected with a rotating assembly for driving the clamping plates to rotate, and the workbench is connected with a chamfering assembly.

[0008] By adopting the above technical solution, the driving component drives the distance between one support plate and another support plate, so as to be suitable for rods of different lengths. The rod is placed at the corresponding position, and the linkage component on the support plate drives the corresponding clamping plate to slide in the direction close to the rod, so that the rod is clamped by the clamping plate, thereby improving the stability of the rod placement. The rotating component drives the clamping plate to rotate, that is, the rod rotates around its own axis. Since the rod is clamped by the clamping plate, the horizontal movement of the rod during the rotation is reduced, thereby improving the stability of the rod rotation. The chamfering component chamfers the rod, and since the stability of the rod rotation is improved, the chamfering effect of the chamfering component on the rod is improved.

[0009] Optionally, the support plate is rotatably connected to a mounting shell, the support plate is provided with a rotating hole for rotatably cooperating with the mounting shell, the mounting shell is connected with a limiting structure for limiting the mounting shell from being separated from the support plate, the rotating assembly is used to drive the mounting shell to rotate, the mounting shell is connected to a carrier plate, the clamping plate is slidably connected to the carrier plate, the carrier plate is provided with a sliding groove for slidably cooperating with the clamping plate, the inner wall of the sliding groove is connected with a guide block, and the clamping plate is provided with a guide groove for slidably cooperating with the guide block.

[0010] By adopting the above technical solution, the rotating assembly drives the mounting shell to rotate. Since the clamping plate is slidably connected to the carrier plate, the clamped rod rotates with the rotation of the mounting shell. The limiting structure prevents the mounting shell from separating from the support plate during the rotation process, thereby improving the stability of the rotation of the mounting shell. When the clamping plate slides, the sliding cooperation of the guide block and the guide groove plays a role in guiding and limiting the sliding of the clamping plate, thereby improving the stability of the sliding of the clamping plate, that is, improving the effect of the clamping plate clamping the rod.

[0011] Optionally, the limiting structure includes a limiting ring connected to the mounting shell, and the support plate is provided with an annular groove for rotatably cooperating with the limiting ring, and the annular groove is communicated with the rotating hole.

[0012] By adopting the above technical solution, when the mounting shell rotates, the limit ring rotates around the annular groove, and the rotation of the limit ring and the annular groove cooperate to guide and limit the rotation of the mounting shell, thereby improving the stability of the rotation of the mounting shell and preventing the mounting shell from separating from the support plate during the rotation process.

[0013] Optionally, the linkage assembly includes an active block slidably connected to the support plate and a first driving member for driving the active block to slide toward or away from the carrier plate, the first driving member being connected to the support plate, the first driving member being rotatably connected to the active block, the active block being connected to each of the clamping plates via a connecting rod, and the two ends of the connecting rod being rotatably connected to the active block and the clamping plate respectively.

[0014] By adopting the above technical solution, the bar is placed between the clamping plates, the first driving member drives the active block to slide in the direction away from the carrier plate, the active block drives each connecting rod to rotate, and each connecting rod drives the corresponding clamping plate to slide in the direction close to the bar, so that the bar is clamped by the clamping plate, improving the stability of the clamping plate placement. The rotating assembly drives the mounting shell to rotate, and the connecting rod and the active block rotate with the rotation of the mounting shell. Since the first driving member is rotatably connected to the active block, the first driving member is prevented from hindering the rotation of the active block.

[0015] Optionally, the rotating assembly includes a driving gear rotatably connected to the support plate and a driven gear connected to the mounting shell, the driving gear meshes with the driven gear, and the support plate is connected to a second driving member for driving the driving gear to rotate.

[0016] By adopting the above technical solution, the second driving member drives the driving gear to rotate, and the driving gear drives the driven gear to rotate, so that the mounting shell rotates around its own axis, thereby realizing the rotation of the clamping plate and the rod. The driving gear and the driven gear provide conditions for the rotation of the mounting shell, preventing the first driving member from obstructing the second driving member.

[0017] Optionally, a side of the clamping plate close to the axis of the carrier plate is in an arc shape.

[0018] By adopting the above technical solution, the arc-shaped clamping plate is used to increase the contact area between the clamping plate and the rod, thereby increasing the friction between the clamping plate and the rod and improving the effect of the clamping plate clamping the rod.

[0019] Optionally, a buffer pad is connected to a side of the clamping plate close to the axis of the carrier plate.

[0020] By adopting the above technical solution, the buffer pad is used to prevent the clamping plate from directly contacting the rod, disperse the pressure of the clamping plate clamping the rod, and protect the rod.

[0021] Optionally, the driving assembly includes a first screw rod rotatably connected to the workbench and a third driving member for driving the first screw rod to rotate, the support plate is threadedly connected to the first screw rod, the third driving member is connected to the workbench, and the support plate is in contact with the workbench.

[0022] By adopting the above technical solution, the third driving member drives the first screw rod to rotate around its own axis. Since the support plate is threadedly connected to the first screw rod and the support plate is in contact with the workbench, the support plate slides along the length direction of the first screw rod, thereby facilitating the adjustment of the distance between the support plate and another support plate.

[0023] Optionally, the workbench is slidably connected to a movable plate, the movable plate is connected to a bracket, the workbench is connected to a movable component for driving the movable plate to slide along the length direction of the first screw rod, the bracket is slidably connected to a mounting frame, the bracket is connected to a fourth driving member for driving the mounting frame to slide toward or away from the workbench, and the chamfering component is connected to the mounting frame.

[0024] By adopting the above technical solution, the fourth driving member is used to adjust the distance between the chamfering assembly and the rod, so that the chamfered end of the chamfering assembly fits with the rod, and the moving assembly drives the moving plate to slide along the length direction of the first screw rod, thereby realizing the chamfering of the chamfering end of the chamfering assembly along the length direction of the rod.

[0025] Optionally, the chamfering assembly includes a chamfering roller rotatably connected to the mounting frame and a fifth driving member for driving the chamfering roller to rotate, and the fifth driving member is connected to the mounting frame.

[0026] By adopting the above technical solution, the fifth driving member drives the chamfering roller to rotate, thereby realizing the chamfering roller to rotate around its own axis, so that the chamfering roller chamfers the outer peripheral surface of the rod.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. The rotating assembly drives the clamping plate to rotate, that is, the bar rotates around its own axis. Since the bar is clamped by the clamping plate, the horizontal movement of the bar during the rotation is reduced, and the stability of the bar rotation is improved. The chamfering assembly chamfers the bar, which improves the stability of the bar rotation, that is, the chamfering effect of the chamfering assembly on the bar is improved.

[0029] 2. The rotating assembly drives the mounting shell to rotate, and the connecting rod and the active block rotate along with the rotation of the mounting shell. Since the first driving member is rotationally connected to the active block, the first driving member is prevented from hindering the rotation of the active block. BRIEF DESCRIPTION OF THE DRAWINGS
