Embodiment Construction

[0026] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0027] like Figure 1~3 The shown wide-width CNC stamping transposition clamping secondary positioning device includes a two-dimensional plane driving mechanism 5 that can be used for horizontal and vertical movement in front of the punching machine 1. The structure and working principle of the two-dimensional plane driving mechanism 5 are existing Technology, so I won’t go into details here.

[0028] Two sets of sheet clamps 4 with adjustable relative positions are arranged on the two-dimensional planar driving mechanism 5. The sheet clamps 4 are used to laterally clamp the outer edge of the processed wide sheet 8, thereby controlling its relative position The upper mold 10 and the lower mold 9 of the punch press 1 move horizontally and vertically.

[0029] Two driving cylinders 2 are arranged on the bed upper part of the punching ...

Abstract

The invention discloses a method and a device for secondary clamping positioning of wide numerical control punching and interchanging. The method comprises the following steps of by utilizing the loosening, moving back and re-clamping of a sheet clamp, completing the long-distance punching process of a to-be-processed wide sheet by sections; in the interchanging process of the sheet clamp, enabling driving air cylinder compressing mechanisms at the upper part and lower part of a punch press body to firmly clamp and fix the to-be-processed wide sheet, so as to guarantee the accuracy of secondary positioning and clamping. The device mainly consists of a two-dimensional plane driving mechanism, the sheet clamp, driving air cylinders, sheet pressing blocks, sheet support cushions and the like, wherein the two-dimensional plane driving mechanism is arranged in front of the punch press, the sheet clamp is arranged on the two-dimensional plane driving mechanism, the position of the sheet clamp can be adjusted, the driving air cylinders and the sheet pressing blocks are arranged at the upper part of the punch press, and the sheet support cushions are arranged at the lower part of the punch press. The method and the device have the characteristics that the method is skillful and rapid, and the structure is simple and compact; the full-width processing of the larger-width metal sheet punching can be completed by the smaller single clamp stroke, and the interference with a punching die can be avoided by adjusting the position of the sheet clamp.

Description

technical field [0001] The invention relates to a clamping technology in numerical control stamping processing, in particular to a secondary positioning method and device for wide-width numerical control stamping transposition clamping. Background technique [0002] In the field of CNC stamping processing, the sheet to be processed is generally clamped by the traditional sheet clamp, and then the two-dimensional plane driving mechanism drives the sheet clamp to realize the feeding and stamping of the sheet. For large-format sheet metal processing, it is often necessary to have a very long stroke of the sheet metal clamp to ensure the requirements of the processing format. However, if the stroke of the sheet clamp is too long, the entire mechanical equipment will be bulky, and the requirements for the rigidity and precision of the moving parts and transmission parts will also be correspondingly increased, resulting in a substantial increase in manufacturing costs. Therefore,...
