Luggage pull rod multi-thickness pressing groove anti-clamping mark device

Abstract

The invention relates to the technical field of luggage pull rod machining, and discloses a luggage pull rod multi-thickness pressing groove anti-clamping mark device. The device comprises a pressure hammer, wherein a first electromagnet is fixedly connected to the surface of the pressure hammer, a base is arranged under a pressing groove rod, a sliding groove is movably connected with a fixing rod, a pressure groove is formed in the upper surface of the fixing rod, a pressure conduction device is fixedly connected to the bottom face of the pressure groove, a piezoelectric device is fixedly connected to the bottom of the pressure conduction device, a second electromagnet is fixedly connected to the surface of the clamping plate, an electric telescopic rod is fixedly connected to the side face of the fixing rod, and a third electromagnet is fixedly connected to the surface of the base. According to the luggage pull rod multi-thickness pressing groove anti-clamping mark device, the electric telescopic rod and a hydraulic machine are used in cooperation to manufacture a pull rod groove, the piezoelectric device is extruded through deformation of a pull rod, when the thicknesses of the pull rod are different, the electromagnet current is changed to enhance magnetism, the pressure borne by the pull rod is controlled to conduct groove pressing and clamping force of a clamping plate on the pull rod, and clamping marks are prevented from being generated.

Description

technical field [0001] The invention relates to the technical field of luggage trolley processing, in particular to a multi-thickness groove-preventing device for luggage trolleys. Background technique [0002] The trolley case refers to a suitcase with a trolley and a roller. It is widely used because of its convenience. In order to facilitate dragging when walking, it greatly reduces the burden. In order to save effort when dragging, double-roller, four-roller and six-roller suitcases have appeared. Out of the cylindrical trolley case, to adapt to more terrain. [0003] In the production of pull rods for luggage, hydraulic machines are often used to process the grooves of the rods. Because the materials used for the rods are different, the deformation of the rods is different when the rods are pressed, and the thickness of the rods is not uniform. , for this reason, it is necessary to frequently set the pressure intensity of the hydraulic press, and in the process of gro...
