Description

Synchronous motion control type continuous feed method and apparatus for press workpieces

The present invention relates to a synchronous motion controlled press workpiece continuous transfer method and apparatus thereof, and more particularly, to increase productivity by using a synchronous motion control method to manufacture a press workpiece for large automobile and ship parts by a multi-process press method, and to press the press workpiece. Its main purpose is a synchronous motion controlled press workpiece continuous feed method and device capable of continuous work and workpiece feed without stopping motion of the machine.

In general, industrial presses are separated into upper and lower molds according to the shape and size of the workpiece to be manufactured, and pressurize the workpiece seated in the lower mold through a pressurizing press that moves up and down from the upper side to transform it into various shapes. .

These presses use a method in which the volume of the workpiece is large in proportion to the size of the shape or the shape of the workpiece is sequentially moved through at least one press to pressurize and deform the shape of the workpiece little by little to complete the workpiece in the form of a final product. .

In addition, after the entire press pressurizes and punches the workpiece of the enlarged press at the same time to deform the workpiece, the workpiece is moved to the next process at the same time in a state where the press completely moves to the upper top dead center Shuttle transfer It is being moved by the unit.

However, this simultaneous pressurizing and moving manufacturing method has a limited production volume according to the working time of the press process and the moving process, so in order to increase the production volume, there is an inevitable problem of increasing the size and molding process due to the installation of additional presses and moving units,

In addition, when the structure and shape of the molding pattern formed by pressing, cutting, bending, etc. on the plate surface of the plate material is diverse and complex, that is, when there are relatively many molding processes, upper and lower parts having dies and punches corresponding to each process There is a problem that the pressurization time of a plurality of presses equipped with molds may be slightly different,

In addition, these existing methods have a problem in that productivity is low and a continuous production process cannot be performed, resulting in a decrease in price competitiveness, and various solutions have been proposed accordingly.

Recently, various types of prior art related to workpiece presses and transfer methods have been known.

For example, in Korean Registered Patent Publication No. 10-0923904 (published date: 2004.04.30.), “A first conveyor for transporting products to be processed; a robot equipped with processing means for performing processing necessary for the product; a second conveyor located in the working area of the robot and separated from the first conveyor and movable up and down; Elevating means for moving the second conveyor up and down; And a fixture fixed to maintain the height of the product even when the second conveyor descends, and rotatable to rotate the product in a space formed by the descent of the second conveyor so that a desired surface can come to the lower side of the processing means of the robot.

As described above, various types of continuous conveying methods for press workpieces and technical details related to the device are known and used.

In Korean Patent Registration No. 10-0923904, the product can be rotated in the work area.

The purpose is to provide a multi-directional processing device that enables multi-directional work that enables screw fastening, welding, component mounting, etc. on an arbitrary work surface with one robot and does not require additional workers for product reversal. Another purpose is to provide a multi-directional processing device that can reduce the waiting time in each product manufacturing process by distributing the workload similarly to each robot by configuring the robots as one line, but moving along the conveyor The workpiece to be processed is rotated at an arbitrary angle by a robot processing means, but this is the case in the case of a single-acting press, but there is a problem in that mass production is difficult in one or more continuous press processes, and thus a lot of production cost increases. There are inherent structural problems that are difficult to apply to the manufacture of ships and automobile parts, and there is a problem that the production cost increases accordingly due to the decrease in production efficiency in the sequential method.

In addition, in Korean Patent Registration No. 10-0941696, the center of the transfer arm in the transfer device is moved so that the transfer pitch can be changed as much as the center of the transfer arm is transferred, so that the pitch transfer can be changed simply without replacing parts, At the same time, the transfer arm is rotated in an "X" shape around the pitch transfer axis, and the transfer pin is transferred through this to reduce vibration due to the balance of moving parts, thereby realizing high-speed with light weight. Although it provides a material conveying device, it is specialized in conveying press materials for semiconductor packages, so it is difficult to apply to other continuous press processes, and the principle of moving the opposite end upward relative to the rotation axis is difficult to apply. There is a critical problem.

In addition, Korean Patent Registration No. 10-1625003 aims to provide a swing press for forging that can greatly reduce the molding load, but there is a problem in that the production cost increases due to press manufacturing, and it is difficult to apply to an existing press machine. There are difficult structural problems, and there are problems that are difficult to apply in large automatic motion presses.

In addition, Korean Patent Registration No. 10-1600311 aims to provide a continuous parts supply device that enables continuous assembly of assemblies formed by sequentially welding a plurality of unit parts through one production line and a single worker. Its purpose is to provide a continuous parts supply device that can reduce overall costs and improve work productivity by enabling operation by Since there is no structure, there is an inherent structural problem that continuous operation cannot be performed, and because it is a simple structure that can be simply picked up and rotated to be used in other processes, it is difficult to apply during the continuous press process, and mass production with a simple automated loading method There is this difficult problem, and there is a problem that the range of rapid workpiece movement is limited because there is no single-acting unit that moves between each press.
