Embodiment 1

[0053] combine figure 1 The steel ball billet measurement diagram of the existing steel bar in the workshop without fixed length. After the steel billet is unfolded on the display table, a CCD camera is set at the material turning position, and the distances L1 and L2 between the CCD camera and the billet are measured respectively. The blank length L=L0-L1-L2 is calculated by the controller. The length measurement adopts the camera length measurement equipment with high precision, and the repeat error of a single equipment is ±0.5mm.

[0054] After the steel bar is measured by the machine vision system, the length of the steel bar is accurately measured to be 5600mm, and the length is determined. After the data is transmitted to the computer, the program runs, and the program calculates that the steel bar is divided into 28 sections, with an average length of 200mm. . The turning mechanism automatically turns the blank with a measured length to the cutting position. At this ...

Embodiment 2

[0058] combine figure 1 The steel ball billet measurement diagram of the existing steel bar in the workshop without fixed length. After the steel billet is unfolded on the display table, a CCD camera is set at the material turning position, and the distances L1 and L2 between the CCD camera and the billet are measured respectively. The blank length L=L0-L1-L2 is calculated by the controller. The length measurement adopts the camera length measurement equipment with high precision, and the repeat error of a single equipment is ±0.5mm.

[0059] After the steel rod is measured by the machine vision system, the length of the steel rod is accurately measured to be 6650mm, and the length is determined. After the data is transmitted to the computer, the program runs, and the program calculates that the steel rod is divided into 33 segments, with an average length of 201.5 mm. mm. The turning mechanism automatically turns the blank with a measured length to the cutting position. At ...

Embodiment 3

[0063] combine figure 1 The steel ball billet measurement diagram of the existing steel bar in the workshop without fixed length. After the steel billet is unfolded on the display table, a CCD camera is set at the material turning position, and the distances L1 and L2 between the CCD camera and the billet are measured respectively. The blank length L=L0-L1-L2 is calculated by the controller. The length measurement adopts the camera length measurement equipment with high precision, and the repeat error of a single equipment is ±0.5mm.

[0064] After the steel rod is measured by the machine vision system, the length of the steel rod is accurately measured to be 5900mm, and the length is determined. After the data is transmitted to the computer, the program runs. The rod length is 5900mm. When the machine cuts a single 200mm, the final remaining 100mm After the program compiled by this algorithm, the steel bar is divided into 29 sections, each with an average of 203mm, the loss ...

Abstract

The invention discloses an efficient and accurate round steel automatic sizing system, and relates to the technical field of metal bar sizing. The method comprises the specific steps that first, machine vision distance measurement is conducted, and the length of a steel bar is measured by adopting a machine vision system; second, automatic sizing is carried out, algorithm compiling operation is designed in a C language programming environment, and the requirements for the qualification rate and the yield of sizing of a steel ball blank are met; and third, system control is performed, the related production technologies and processes include length measurement, material turning, calculation and cutting, and press breaking and alignment, and the round steel automatic sizing system is composed of a PLC unit (1), a machine vision detection unit (2), a display unit (3), a calculation unit (4), a power supply system, a production workshop logistics scheme, matters needing attention and the like. By optimizing the steel bar length measurement and steel bar automatic sizing control system, the sizing precision is high, the sizing is stable, calibration is simple, installation, debugging, operation and maintenance are easy, the operation cost is low, cutting is accurate, the sizing rate and the yield are increased, and the rejection rate is lowered.

Description

technical field [0001] The invention relates to the technical field of forging and pressing wear-resistant steel ball and round steel blanks to length, in particular to an efficient and accurate automatic length-sizing and control system for steel rods. Background technique [0002] In the production process of wear-resistant steel balls, the accuracy of the sizing accuracy of round steel rods affects the output, product quality and cost of steel balls. With the changes in the market and the improvement of the quality requirements for steel balls, the cost pressure is increasing, and there are more and more cut-to-length specifications. The cut-to-length accuracy and efficiency are becoming more and more important in the production of wear-resistant steel balls. At present, the existing automatic bar cutting machines generally use infrared photography to determine the length, but the anti-interference is relatively poor, the billet cannot recognize the ambient temperature is...
