Embodiment Construction

[0012] Such as figure 1 is a sectional view of the present invention, figure 2 It is a top view of the present invention, a high-efficiency lace machine tool pin shaft, including a shaft body 1, and a positioning hole 2 is provided in the center of the shaft body 1. The shaft body 1 is made of high chromium alloy material. A boss 3 with a square cross-section is provided on both sides of the cross-section of the shaft body 1 .

[0013] Since the shaft body 1 is made of high chromium alloy material, in order to improve the smoothness of the surface, it needs to be ground. There is a boss 3 with a square cross section on both sides of the cross section of the shaft body 1, which provides convenience for clamping during grinding; Knife is movably arranged in closing knife seat and closing knife seat cover by shaft body 1, and closing knife keeps swinging back and forth around shaft body 1 along the guide groove in closing knife seat and closing knife seat cover during work. T...

Abstract

The invention relates to the field of sewing machinery, in particular to an efficient lace machine closing knife pin shaft. The pin shaft comprises a shaft body, the center of which is provided with a positioning hole. The shaft body is made of a high-chromium alloy material, two sides of a shaft body cross section are respectively provided with a boss having a square cross section. The positioning hole disposed at the center of the shaft body greatly facilitates installation and positioning of the closing knife and improves the production efficiency of a lace machine. With the shaft body made of the high-chromium alloy material, the wear resistance is greatly improved, and the service life of the pin shaft is prolonged.

Description

technical field [0001] The invention relates to the field of sewing machines, in particular to a high-efficiency lace machine knife pin. Background technique [0002] A knife closing device is usually installed in the lace machine, and several closing knives are movably arranged in the knife closing seat and the knife closing seat cover through metal pin shafts. The knife-off guide groove keeps swinging back and forth; in the process of constantly swinging back and forth during the knife-off, the pin shaft is constantly worn, and the metal pin shaft will not be able to be used normally due to excessive wear in a short time; in addition, due to the pin shaft Without any positioning mechanism, installation and positioning are relatively laborious, which affects the production efficiency of the lace machine. Contents of the invention [0003] In order to overcome the disadvantages of easy wear and troublesome installation of the pin shaft in the existing lace machine knife d...
