Problems solved by technology

The main problems are: 1. For the same batch of raw materials, there is a large deviation in the cross-sectional geometric dimension, and the cross-sectional shape is irregular, and there is also a large error in the measured geometric dimension. For example, using photoelectric and video to measure the geometric cross-sectional dimension, Also affected by the working environment, it is difficult to adapt to the actual production site
2. For different batches of raw materials, the actual density is not the same, and there is a certain error with the standard density
Therefore, the blanking of this method often has a large weight deviation after blanking

Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0028] Such as figure 1 , figure 2 Shown:

[0029] The material is placed on the roller 4 of the feeding frame 1, and the two weighing cylinders 2 are stretched out at the same time, driving the weighing module 3 to lift the material for weighing. Of course, other forms of weighing can also be used here, and the weighing is completed. Finally, the oil cylinder descends, the material is put back on the feeding roller 4, and the length measuring device 5 starts to measure the total length of the material. After the length is measured, the feeding chuck 8 is driven by the feeding servo device 6 to send the material to the sawing chuck The initial position of the outer end surface of 10 is detected and positioned by the position sensor 9 installed on the outer end surface of the feeding chuck to ensure that the end of the material is close to the outer e...

Abstract

The invention discloses a blanking method and a system thereof. The method comprises the following steps of: A. weighing a raw material and measuring the length of the raw material in advance; and figuring out the actually linear density of the material and the length of the needed blanking; B. controlling the feeding stroke according to the blanking length and blanking. The invention avoids the measurement on the section geometric dimension of the raw material, only needs to measure the weight and the length of each material on line so as to obtain the actually linear density and forms the closed cycle control of the blanking length in the terms of length control; therefore, the method is suitable for blanking solid or hollow materials with any section shapes. The invention overcomes the shortcoming of the traditional blanking method, is suitable for production field and increases the blanking precision.

Description

technical field [0001] The invention relates to a blanking method and system thereof, in particular to a material sawing blanking method and system thereof, which are used to realize equal-weight blanking of profiles with various cross-sectional shapes. technical background [0002] Precise blanking of materials is the basis and necessary condition for precise plastic forming of materials to realize the refinement of parts blanks. At present, in actual production, the method of cutting materials is generally used to cut the material to a certain size. The specific method is: measure the cross-sectional geometric dimension of the material with specific size specifications, and then convert it into the length dimension required for each section of cutting according to the standard density of the material, and then saw the material according to this dimension. The main problems are: 1. For the same batch of raw materials, there is a large deviation in the cross-sectional geome...
