Problems solved by technology

[0003] When the punching force of the existing punching machine is unbalanced during punching, that is, when the bottom surface of the table and the slider are not parallel, the judgment and adjustment method is generally a qualitative judgment based on work experience, which is not timely enough and relatively difficult. Error-prone, which in turn can lead to increased press wear

[0063] see Figure 4 , Figure 4 It is a schematic flowchart of the method for detecting the balance of the punching force provided by the second embodiment of the present invention.

[0064] The punching force balance detection method is applied to the main controller 15 of the punching force balance detection device 10 in the first embodiment, and the method includes:

[0065] Step S101: Find the maximum value among the variation distances of each dead point during each stamping, and record the detection point 16 corresponding to the maximum value as the deepest dead point.

[0066] Step S102: Determine whether the number of times when the deepest dead point is the same detection point 16 is greater than the first preset threshold.

[0067] Step S103: When the number of times is greater than the first preset threshold, it is determined that the punching state of the punch press 100 is a state requiring intervention. In other words, when the dead point change distance corr...

Abstract

The invention discloses a stamping force balance detection device and method and a stamping machine, and relates to the technical field of stamping control. The stamping force balance detection devicecomprises a main controller and at least two dead point sensors which are electrically connected with the main controller; each dead point sensor is arranged on a table disc, the position of each dead point sensor serves as a detection point, and the dead point sensors are used for detecting the dead point change distances between the target detection positions, corresponding to the detection points, of a sliding block and a preset standard dead point position when the sliding block falls to the lower dead point; and the main controller is used for determining a maximum value in all the deadpoint change distances generated in each time of stamping as a deepest dead point, and when the number that the dead point change distance corresponding to the same detection point is continuously determined as the deepest dead point exceeds a first preset threshold value, it is determined that the stamping state of the stamping machine is an intervention needing state. According to the stamping force balance detection device and method and the stamping machine, the stamping state can be stably and accurately judged.

Description

technical field [0001] The invention relates to the technical field of punching control, in particular to a punching force balance detection device, method and punching machine. Background technique [0002] The punch press is mainly used for stamping production, which is mainly for plates. Through the mold, blanking, punching, forming, deep drawing, trimming, fine blanking, shaping, riveting and extrusion, etc. can be made, which are widely used in various fields. [0003] When the punching force of the existing punching machine is unbalanced during punching, that is, when the bottom surface of the table and the slider are not parallel, the judgment and adjustment method is generally a qualitative judgment based on work experience, which is not timely enough and relatively difficult. Error-prone, which in turn can easily lead to increased wear on the press. [0004] In view of this, it is particularly important to develop and design a punching force balance detection devi...
