Description

Technical Field

[0001] The present invention relates to a transfer table design for a fully automated forging line capable of realizing incoming material detection, and is particularly applicable to the forging field, where no human involvement is required throughout the entire process, and a robot fully automatically transfers and transports hot bar materials between forging equipment according to different workstations through signals sent by a detection mechanism of the transfer table, and applies the transfer table in a fully automated forging production line. Background Art

[0002] With the deepening of industrial transfer and the development of my country's high-end equipment manufacturing industry, some domestic forging enterprises have made great progress in forging technology, forging equipment level and forging capacity by absorbing and introducing technology, strengthening R&D cooperation and technology accumulation. At present, the domestic forging (front axle and crankshaft) production line basically continues the German technology of the 1980s. This technology has the following disadvantages in full automation: hot die forging hands and conveyor belts are used to transport and convey forgings, among which the loading, unloading and inter-station transfer of forgings on the press are realized by hot die forging hands, and the transmission of forgings between presses is realized by conveyor belts. However, the hot die forging hand is a coordinate structure with low degree of freedom, inflexible operation and high failure rate; while the conveyor belt has low positioning accuracy and long forging conveying time. Therefore, this forging handling and conveying method using hot die forging hands and conveyor belts has the disadvantages of high failure rate and low production efficiency.

[0003] The present invention solves the above-mentioned defects and has the following technical advantages: a forging-specific robot is used to replace the original hot die forging hand with a low degree of automation, and the conveyor belt with low positioning accuracy and long conveying time is eliminated. The entire line adopts a transfer table that can accurately locate and detect incoming materials, and adopts a bus control method to achieve fully automated production, with a high degree of automation, high production efficiency, and a low failure rate. Summary of the invention

[0004] The present invention discloses a transfer table design for a fully automated forging line capable of realizing incoming material detection, that is, in the fully automated forging line, a robot fully automatically transfers and conveys between forging equipment with the aid of the transfer table, a master control system of the forging line locates the position of forgings through signals emitted by an incoming material detection device of the transfer table, and then commands the robot to grab the forgings on the transfer table and transfer the forgings between different robots through the master control system, and the transfer table is applied to an unmanned fully automated forging production line.

[0005] The transfer table consists of three parts: a material receiving rack, a bracket and a detection mechanism; the detection mechanism consists of six parts: an adjusting bolt, a push rod, a guide sleeve, a spiral spring, a travel switch and a travel switch bracket; the adjusting bolt is adjustable in height, and the adjustment range is 70mm; the push rod is lifted to a certain height under the action of the spring. When the forging is placed on the material receiving rack, the push rod is pressed down to compress the spring, and at the same time, the push rod moves down 20mm to rotate the travel switch and send a forging arrival signal to the main control system. After the robot takes the forging on the material receiving rack, the push rod is lifted and reset under the action of the spring; the push rod is designed with a boss d2=φ32mm, h5=166mm, and a push rod diameter d1=φ25mm; the screw hole depth h6=95mm; h3=7mm, h4=103mm, h7=130mm, D2=φ56mm; the forging is placed on the material receiving rack, the lowest point of the forging is h=20mm higher than the highest point of the adjusting bolt, and the material receiving rack β=80°.

[0009] In this embodiment Figure 1 This is the assembly drawing of the transfer table. Number 1 is the material receiving rack, and there is one on each side of the detection mechanism. Number 2 is the bracket, and number 3 is the detection mechanism. Number 13 is the travel switch mounting plate, which is used to fix Figure 3 The middle travel switch 9 is at a height of h2 = 500 mm from the ground; reference numeral 10 is a fixing plate of the guide sleeve 6, at a height of h1 = 870 mm from the ground; the distance between the two uprights of the bracket is L1 = 600 mm.

[0010] Figure 2 It is a side view of the transfer table, the width of the fixed plate 10 is L2 = 270mm, the angle of the receiving rack 1 is β = 80°, and the reference numeral 11 is the cross section of the forging received by the receiving rack, which can be circular or in other shapes. The forging is placed on the receiving rack, and the lowest point of the forging is h = 20mm higher than the highest point of the adjusting bolt.

[0011] Figure 3It is an enlarged view of the transfer table detection mechanism. The number 4 is the adjustment bolt, which is adjusted according to the required height of different forgings so as to detect that the forgings are on the receiving rack; the number 5 is the push rod, the diameter of the push rod is d1 = d3 = φ25mm, the threaded hole depth of the push rod is h6 = 95mm, there is a boss under the push rod, the boss is h5 = 166mm from the bottom of the push rod, and its diameter is d2 = φ32mm; the number 6 is the guide sleeve, the guide sleeve has a submerged seat, and is embedded in the fixed plate 1 by the submerged seat 0, the diameter of the submerged seat D1 = 100mm, the thickness h3 = 7mm; the total length of the guide sleeve h7 = 130mm, the distance between the submerged seat and the bottom surface of the guide sleeve h4 = 103mm, the bottom of the guide sleeve has a cover 12, the spiral spring 7 is installed at the lower part of the guide sleeve, and is sealed inside the guide sleeve by the boss of the push rod and the cover 12 of the guide sleeve. The outer diameter of the guide sleeve D2 = φ56mm, the number 8 is the travel switch, the number 9 is the travel switch bracket, and the number 13 is the travel switch mounting plate.
