Embodiment Construction
[0035] The invention discloses a closing device and a centering closing method. The method includes: a main control system, which is used to set a product specification corresponding to a tubular cylinder to be closed, and the product specification includes at least the outer surface of the tubular cylinder to be closed. Diameter parameter and length parameter; Clamping jaw device, comprises the first clamping cylinder that is positioned at the lower side of said tubular cylinder to be closed and the second clamping cylinder that is positioned at the upper side of said tubular cylinder to be closed, for according to said Product Specifications The tubular cylinder to be closed is fixed at the first position through the expansion and contraction of the first clamping cylinder and the second clamping cylinder, and the first position is the outer edge of the tubular cylinder to be closed. The position corresponding to the diameter parameter; the thimble device, including a thimble...

The invention discloses closing-in equipment and a centering closing-in method. The technical problem of poor closing-in accuracy of a pipe during industrial production is solved. The closing-in equipment comprises a master control system, a clamping claw device, an ejector pin device and a closing-in mould. The master control system is used for setting product specification corresponding to a to-be-closed-in tubular cylinder; the clamping claw device comprises a first clamping air cylinder and a second clamping air cylinder and used for fixing the to-be-closed-in tubular cylinder to the first position through retractable movement of the clamping air cylinders, and the first position is the position corresponding to the outer diameter parameter of the to-be-closed-in tubular cylinder; the ejector pin device comprises an ejector pin and a positioning sleeve, the ejector pin is located in the axis position of the positioning sleeve, and the positioning sleeve is used for being connected with the outer surface of the to-be-closed-in tubular cylinder in a sleeved mode; the outer diameter of the ejector pin is smaller than the inner diameter of the to-be-closed-in tubular cylinder, and the ejector pin and the axis of the to-be-closed-in tubular cylinder are overlapped during sleeved connection; the closing-in mould is used for performing closing-in treatment on the first end of the to-be-closed-in tubular cylinder on the basis of the ejector pin.
Description
technical field [0001] The invention relates to the field of machinery, in particular to a mouth closing device and a centering mouth closing method. Background technique [0002] With the rapid development of science and technology and the increasingly fierce market competition, industrial production has always attracted people's attention. Among them, the application of pipe fittings manufacturing in industrial product structure occupies an important position. Due to the needs of product structure design, pipe fittings are often required to have various special diameters or shapes. Closing is a process of reducing the diameter of a pre-stretched cylindrical or tubular workpiece through a closing die. As a high value-added technology, the closing forming technology has been widely valued, and the closing products are also widely used. In electrical, chemical and other fields. [0003] At present, in the process of mass production of cylinders with variable cross-section a...
