Description

Technical Field

[0001] The invention relates to the field of copper bar production, and in particular to a copper bar sizing processing method. Background Art

[0002] In modern industrial production, copper bars are widely used in electronics, construction, machinery manufacturing and other fields due to their good electrical conductivity, thermal conductivity and corrosion resistance. Conventional copper bar production is to process the copper raw materials into copper rods through methods such as the up-drawing method, and then extrude them into copper bars, and then draw them into the required cross-sectional shape, and then saw them into uniform lengths for storage. After the user purchases the copper bars, they can cut them into copper bars, copper busbars and other products of the required length according to their needs. Traditional indefinite-length copper profiles often require on-site secondary processing when used, which is not only time-consuming, but may also lead to material waste due to insufficient processing precision.

[0003] With the diversification and refinement of copper busbar demand in various industries, copper profile product cut-to-length processing service has emerged. The so-called cut-to-length processing means that copper profiles are accurately cut and processed according to specific length, width, thickness and other dimensions according to the specific needs of customers.

[0004] The cut-to-length processing can directly provide copper profiles that meet the requirements, reducing the processing links and improving production efficiency. From the perspective of cost control, through cut-to-length processing, enterprises can purchase according to the actual usage, reduce the generation of surplus materials, and reduce material costs. Moreover, due to the reduction of labor and equipment investment in on-site processing, the overall cost is also effectively controlled. From the perspective of product quality assurance, professional cut-to-length processing equipment and technology can ensure the dimensional accuracy of copper profiles and ensure the stability of product quality. Summary of the invention

[0005] The present invention aims to provide a copper bar sizing processing method, so as to realize timely sizing processing of the copper bar after production.

[0006] To achieve the above object, the present invention adopts the following technical solution: a copper bar sizing processing method, comprising the following steps:

[0007] A. Drawing the copper bar blank on an automatic hydraulic drawing machine;

[0008] B. Saw the end of the drawn copper bar at the outlet of the automatic hydraulic drawing machine;

[0009] C. The copper bar sawn in step B is moved to the transmission table under the push of the automatic hydraulic drawing machine, and the end of the copper bar is blocked and positioned by a liftable fixed-length baffle at the end of the transmission table, and the waste material at the head end of the copper bar is cut off by a fine saw in the middle of the transmission table;

[0010] D. Lower the head end of the transmission platform to raise or lower the fixed-length baffle, and the transmission platform rotates clockwise to output the waste;

[0011] E. Reverse the transmission platform to move the copper bar to expose it and raise the liftable fixed-length baffle at the head end of the transmission platform. Then use the transmission platform to rotate clockwise to move the copper bar until it is against the liftable fixed-length baffle at the head end of the transmission platform. Use a fine saw to cut the copper bar into two fixed-length products in the middle of the transmission platform.

[0012] F. Lower the lifting and lowering baffle plate and use the transmission platform to output the two copper bars of fixed length;

[0013] During step B to step F, the lifting and lowering of the liftable fixed-length baffle is controlled by a time relay to delay the lifting and lowering, and the delay time matches the production speed of the automatic hydraulic drawing machine.

[0014] Preferably, as an improvement, the liftable fixed-size baffle and the transmission platform in step C and step D are connected in a detachable manner, so that the distance between the liftable fixed-size baffle and the fine saw can be adjusted.

[0015] Preferably, as an improvement, a liftable fixed-size baffle is installed on the transmission platform before step A. When the copper bar is moved to the transmission platform in step C, the transmission platform is first rotated clockwise to move the end of the copper bar forward to expose the liftable fixed-size baffle at the end of the transmission platform, and then the liftable fixed-size baffle is lifted, and then reversed to position the end of the copper bar against the liftable fixed-size baffle.

[0016] Preferably, as an improvement, the liftable fixed-size baffle includes a base plate, two supporting ear plates are arranged side by side on the base plate, a flip baffle is rotatably connected between the two supporting ear plates, a driving member is connected to the base plate, the driving member is used to drive the flip baffle to flip so that the flip baffle is in a horizontal or vertical state, when the flip baffle is in a vertical state, the copper bar is blocked and positioned, and when the flip baffle is in a horizontal state, it is lower than the supporting plane of the transmission platform.

[0017] Preferably, as an improvement, a stopper is provided on the supporting ear plate, and the flip baffle is in a horizontal state against the stopper during the rotation process.

[0018] Preferably, as an improvement, a positioning hole is provided on the bottom plate, and the bottom plate is detachably connected to the transmission platform frame through the positioning hole and fasteners.

[0019] The principle of this scheme is as follows: after the first end cutting is completed by setting a fine saw at the exit of the drawing machine, the copper bar is coordinated with the forward / reverse movement of the transmission table and the lifting and lowering baffle to realize the coordinate control of the copper bar segment cutting. The time relay dynamically adjusts the timing of the baffle lifting and lowering to accurately match the drawing speed and ensure positioning accuracy. Utilizing the transmission table's head and tail double baffle system, the head end of the deformed waste generated after drawing is first positioned and cut off by the end baffle, and then the head end baffle is used for secondary positioning to achieve fixed-length segmentation. The liftable fixed-length baffle adopts a detachable connection method, and its position on the transmission table can be adjusted according to different fixed-length copper bar size requirements. The adjustable spacing design adapts to different fixed-length requirements and supports rapid adjustment of cutting stations. The flip baffle structure (horizontal / vertical state switching) avoids interference with the movement of the transmission table while ensuring the blocking and positioning function, thereby realizing a compact layout of the equipment.

[0020] The advantages of this solution include:

[0021] 1. When customers have a need for fixed-length processing, this method can directly perform continuous fixed-length sawing operations after the drawing process is completed. This mode avoids the cumbersome process of subsequent reprocessing in traditional processes, greatly improving production efficiency. At the same time, it reduces additional processing links, greatly reduces sawing costs, and effectively improves the economic benefits of the enterprise.

[0022] 2. This solution cleverly achieves multi-size cuts in the same process without increasing the floor space of conventional automatic hydraulic drawing machines. Through the reasonable design and coordinated operation of the transmission platform and the liftable cut-to-length baffle, the copper bars can be processed in different sizes continuously to meet the diverse market needs. The production process is smooth and efficient without the need for additional site investment.

[0023] 3. During the copper bar drawing process, after a single drawing, the sawing position and the drawing die mouth will be deformed due to the disappearance of stress, and this part needs to be sawed and scrapped. This solution can make the fine saw after the sizing just saw the part of the waste by accurately adjusting the position relationship between the liftable fixed-length baffle and the fine saw, and using the time relay to control the coordination time of each process, so as to avoid excessive material waste, effectively reduce material costs, and improve resource utilization.
