Description

Technical Field

[0001] The invention belongs to the technical field of aluminum busbar processing, and in particular relates to a chamfering sawing machine. Background Art

[0002] With the development of aluminum electrolysis industry towards large-scale and the increasing requirements for energy conservation and consumption reduction, one of the important components used in the aluminum electrolysis industry is the anode conductive rod. The anode guide rod is a conductor used to connect the anode busbar and the anode steel claw of the electrolytic cell in the aluminum electrolysis process, and plays an important role in conducting electricity and suspending anode carbon blocks.

[0003] The aluminum busbar is the conductor for the current to enter and exit the electrolytic cell. The current is transmitted from the aluminum busbar to the anode guide rod through the contact surface. It sends high-power direct current, so that the high direct current passes through the electrolysis link from the positive electrode, and finally comes out from the electrolysis negative electrode to the rectifier cabinet. The aluminum busbar has high purity, low impurity content that affects conductivity, and good conductivity. The aluminum busbar can be up to 14 meters in length, with a maximum cross-sectional size of 550х250mm, and has small deviation, small bending and twisting, a flat surface, no ripples and cracks, a dense internal structure, no bubbles, slag inclusions and internal cracks, and is easy to install.

[0004] During the production process of aluminum busbars, the aluminum busbars are chamfered at 40 and 45 degree angles according to customer needs. However, during the chamfering process of the aluminum busbars, the four sides of the aluminum busbar ends need to be cut. The existing aluminum busbar cutting devices are all single electric saw cutting devices. Therefore, when the aluminum busbars are chamfered, the aluminum busbars need to be cut four times. When cutting the aluminum busbars in this way, the aluminum busbars need to be moved and rotated many times, and the operation process is cumbersome, which makes the cutting efficiency of the aluminum busbar chamfers low, affecting production efficiency. Summary of the invention

[0005] The present invention aims to provide a chamfer sawing machine to solve the problem in the prior art that the aluminum busbar is moved or rotated multiple times during chamfering cutting, resulting in low production efficiency and complicated operation.

[0006] A chamfering sawing machine in the present scheme includes a frame and a shelf for placing an aluminum busbar, and two sets of chamfering sawing mechanisms are symmetrically arranged on the frame at both ends of the shelf, and the two sets of chamfering sawing mechanisms are respectively used to saw the transverse chamfers and longitudinal chamfers of the ends of the aluminum busbar; the chamfering sawing mechanism includes a "V"-shaped connecting seat, and motors are respectively arranged at both ends of the connecting seat, and an adjustment mechanism for adjusting the motor angle is arranged on the connecting seat, and the output shafts of the two motors are respectively connected to saw blades.

[0007] The working principle of this scheme is: after the aluminum busbar is fixed on the shelf to fix its position, its two ends face the racks on both sides, and the longitudinal chamfering sawing mechanism on the rack moves downward to pass through the ends of the aluminum busbar, and at the same time, the motor drives the saw blade to rotate at high speed to saw and shape the longitudinal chamfer of the ends of the aluminum busbar. After the longitudinal chamfering sawing mechanism rises away from the aluminum busbar, the transverse chamfering sawing mechanism moves transversely to approach and pass through the ends of the aluminum busbar, and at the same time, the motor drives the saw blade in the transverse chamfering sawing mechanism to rotate at high speed, thereby sawing and shaping the transverse chamfer of the ends of the aluminum busbar.

[0008] Furthermore, the two groups of chamfering sawing mechanisms are respectively a transverse sawing mechanism and a longitudinal sawing mechanism; the connecting seat of the transverse sawing mechanism is connected to a transverse driving mechanism for driving its transverse movement, and the connecting seat of the longitudinal sawing mechanism is connected to a longitudinal sawing mechanism for driving its longitudinal movement; the transverse sawing mechanism and the longitudinal sawing mechanism operate alternately.

[0009] Furthermore, the transverse sawing mechanism includes a transverse guide rail, a transverse motor is installed on the transverse guide rail, the output shaft of the transverse motor is connected to a transverse lead screw, the transverse lead screw is threadedly connected to a connecting seat of the transverse sawing mechanism, and the connecting seat of the transverse sawing mechanism is also slidably connected to the transverse guide rail.

[0010] Furthermore, the longitudinal sawing mechanism includes a longitudinal guide rail, on which a longitudinal motor is installed, the output shaft of the longitudinal motor is connected to a longitudinal lead screw, the longitudinal lead screw is threadedly connected to a connecting seat of the longitudinal sawing mechanism, and the connecting seat of the longitudinal sawing mechanism is also slidably connected to the longitudinal guide rail.

[0011] Furthermore, the longitudinal sawing mechanism also includes a tensioning mechanism, which includes a chain and a sprocket, the sprocket is fixed on the frame, the chain tensioning is arranged on the sprocket, one end of the chain is connected to the connecting seat of the longitudinal sawing mechanism, and the other end of the chain is connected to a counterweight block, so as to improve the stability of the longitudinal sawing mechanism during the up and down movement.

[0012] Furthermore, a saw cover is provided at the end of the connecting seat, the size of the saw cover is larger than the size of the saw blade, and the saw cover is used to completely cover the saw blade. The waste generated during the sawing process is blocked by the saw cover to avoid splashing everywhere, making the processing site tidy.

[0013] Furthermore, the frame is provided with a telescopically adjustable positioning push rod aligned with the end of the shelf, and the positioning push rod is used to hold and position the end of the aluminum busbar.

[0014] Furthermore, a locking cylinder for fixing one side of the aluminum busbar is provided on the shelf, and a fixing plate is provided on the shelf on the other side of the aluminum busbar.

[0015] The beneficial technical effects of this solution are:

[0016] 1. This solution has high working efficiency. It only needs to clamp and fix the position of the aluminum busbar once, and then the four chamfers at its end can be quickly sawed and formed. There is no need to turn or move it at noon, and the operation is simple and convenient.

[0017] 2. Before implementing this plan, after adjusting the motor and saw blade inclination according to the chamfer size, it can ensure that all workpieces of the same model requirements are formed at one time, and the chamfer size is not differentiated, ensuring the standardization of forming and production quality.

[0018] 3. After sawing, the aluminum busbar is hoisted as a whole and transferred to the next process, which avoids the major safety hazards during repeated hoisting and repeated clamping and improves processing safety.

[0019] 4. The centers of both ends of the aluminum busbar placed on the shelf are supported and fixed by the positioning push rods, and both sides of the aluminum busbar are clamped and fixed by the locking cylinder and the fixing plate. Multi-point fixation avoids the aluminum busbar from jumping during the sawing process, thereby improving the sawing stability and the flatness of the cut surface. BRIEF DESCRIPTION OF THE DRAWINGS
