Description

Technical Field

[0001] The invention relates to the technical field of mechanical processing, in particular to an automatic punching, drilling and milling production line. Background Art

[0002] In the process of parts processing and production, the transformation of a workpiece from raw materials to finished products often requires a series of complex and delicate processes. These processes include but are not limited to raw material cutting (also known as blanking), punching, drilling, milling, tapping, and chamfering. Each process plays a vital role in the final shape and function of the part.

[0003] However, traditional processing production methods have many limitations and shortcomings. First, the processing equipment that completes these processes, such as punching machines, drilling machines, milling machines, and tapping machines, can mostly only perform a single process. This means that in order to complete the entire processing process of a workpiece, multiple different equipment are required to operate in sequence.

[0004] More importantly, in traditional production processes, the operation of these devices often needs to be completed by multiple technicians with corresponding operating skills and qualifications. They not only need to master the operating skills of their respective processes, but also need to be responsible for material handling and loading and unloading operations. This production method leads to two major problems: first, it is inefficient, because each technician can only complete a single process at his or her position, and the workpiece needs to be frequently transferred between different technicians and different equipment, which increases the production cycle; second, it is costly, because multiple technicians need to be hired, and the maintenance and operation costs of the equipment cannot be ignored.

[0005] In addition, since each technician needs to have certain professional skills and experience, this also increases the difficulty of human resource management and training costs of the enterprise. Moreover, during the transfer and loading and unloading of workpieces, there is also the risk of damaging the workpiece or causing quality problems, which further increases production costs and quality control difficulties.

[0006] In summary, the traditional parts processing production method has obvious deficiencies in efficiency, cost and quality control. Therefore, how to improve and optimize this production process, improve production efficiency, reduce costs and ensure product quality has become an urgent problem to be solved. Summary of the invention

[0007] In view of the deficiencies in the prior art, the present invention provides an automated punching, drilling and milling production line, which solves the problems raised by the above-mentioned background technology.

[0008] To achieve the above objectives, the present invention is implemented through the following technical solutions: an automated punching, drilling and milling production line, comprising a conveyor line bracket, a plurality of groups of workpiece conveying units are installed on the upper part of the conveyor line bracket, a plurality of workpiece lifting units are installed at the conveying end of each workpiece conveying unit, and equipment capable of punching, drilling, tapping and turning and milling the workpieces is respectively arranged along the conveying direction of the workpiece conveying unit and on the back of the conveyor line bracket, and workstations are arranged in the processing area and loading area of ​​each equipment, and the workpiece conveying unit and the workpiece lifting unit jointly perform relay transfer and conveyance on each workstation until the workpiece can be processed by each equipment respectively.

[0009] Furthermore, the equipment needs to include at least a punching machine, a drilling machine, a No. 1 tapping machine, a No. 2 tapping machine, a No. 1 micro CNC milling machine and a No. 2 micro CNC milling machine.

The end of the workpiece bracket away from the bracket mounting seat is integrally connected with a barb, and the direction of the barb is upward.

[0016] Furthermore, the production line also includes an intelligent control system, which includes a central controller, a sensor module, an actuator module and a human-computer interaction interface. The central controller monitors the status and position of the workpiece in real time through the sensor module, and controls the actions of the workpiece conveying unit and the workpiece lifting unit through the actuator module. The human-computer interaction interface is used for the operator to interact with the system.

[0017] Furthermore, the sensor module includes a position sensor, a pressure sensor and a visual sensor, the position sensor is used to detect the position of the workpiece, the pressure sensor is used to detect the lifting force of the workpiece lifting unit, and the visual sensor is used to identify the type and state of the workpiece; the actuator module includes a motor driver, a cylinder controller and a servo controller, the motor driver is used to control the action of the conveying drive device, the cylinder controller is used to control the action of the horizontal drive cylinder and the vertical drive cylinder, and the servo controller is used to control the processing action of the equipment; the human-computer interaction interface includes a touch screen, a button and an indicator light, the touch screen is used to display the system status and operation menu, the button is used to manually control the action of the system, and the indicator light is used to indicate the operating status of the system.

This relay-style conveying method enables the workpieces to be transferred to the right level by level starting from the loading station. Each transfer can complete a processing procedure until all processing procedures are completed. This production method greatly reduces the transfer time and waiting time of workpieces between different equipment, and significantly improves production efficiency.

[0019] 2. Significantly reduce production costs: Due to the realization of automated production, the reliance on manual operation is reduced, so the labor cost can be greatly reduced. At the same time, since the equipment on the production line can work continuously and stably, the damage and rework of workpieces caused by human operation errors are reduced, further reducing production costs.

[0020] 3. Improve product quality: The equipment on the automated production line usually uses precise control systems and sensors to ensure the processing accuracy and consistency of each process. In addition, since human intervention is reduced, quality fluctuations caused by human factors are also reduced. Therefore, this production method can significantly improve product quality and stability.

[0021] 4. Optimize the production process: This technical solution optimizes the production process through reasonable equipment layout and workpiece conveying methods. The connection between each process is closer, reducing waste and bottlenecks in the production process. At the same time, since the equipment on the production line can automatically complete the conveying and processing of workpieces, it also reduces the skill requirements for operators, making the production process easier to manage and control.

[0022] 5. Enhanced production flexibility: The design of the production line has certain flexibility and scalability. By adjusting the number and layout of the workpiece conveying units and the workpiece lifting units, it can adapt to the processing needs of workpieces of different sizes and shapes. In addition, the types and quantities of processing equipment can be increased or decreased according to production needs to meet the production requirements of different products.

Among them, the No. 1 tapping machine 7 and the No. 2 tapping machine 8 perform tapping processing on different parts of the workpiece 11. Similarly, the No. 1 micro CNC milling machine 9 and the No. 2 micro CNC milling machine 10 are also the same). Among the seven workstations 4, the first one is the loading workstation of the workpiece 11, and the others are processing workstations. That is to say, a workstation 4 is set in the processing area of ​​the punching machine 5, the drilling machine 6, the No. 1 tapping machine 7, the No. 2 tapping machine 8, the No. 1 micro CNC milling machine 9 and the No. 2 micro CNC milling machine 10; When the production line is working, the three groups of workpiece conveying units 2 and the eight groups of workpiece lifting units 3 cooperate with each other, so that the workpiece 11 can be transferred to the right side step by step starting from the loading station. Each time the workpiece 11 is transferred, it can be transferred from the station 4 of the previous processing process equipment to the station 4 of the next processing process equipment, thereby forming a relay-type transportation of the workpiece 11 until the workpiece 11 completes all the processing processes and is finally discharged.
