Grabbing mechanism used for sectional material traction and grabbing method thereof

Abstract

The invention provides a grabbing mechanism used for sectional material traction. The grabbing mechanism comprises a power box body, a drive part, a transmission module, two grabbing hand modules androtating shafts, wherein the drive part and the transmission module are arranged in the power box body. The two grabbing hand modules are arranged oppositely up and down in a mirror symmetry manner. In the working process, the drive part drives the two rotating shafts to rotate reversely through the transmission module to drive the two grabbing hand modules of the mirror symmetry to rotate outwards reversely to achieve discharging of sectional materials, or drive the two grabbing hand modules of the mirror symmetry to rotate inwards reversely to achieve grabbing of the sectional materials. Each grabbing hand module is provided with a plurality of pincer claws capable of elastically pressing the surfaces of the sectional materials, and when the sectional materials are grabbed, the pincer claws in the two grabbing hand modules of the mirror symmetry press and locate the surfaces of the sectional materials in a matched manner from the upper portion and the lower portion. The invention further provides a grabbing method for sectional material traction. The grabbing mechanism is high in universality, the sectional materials of any shape can be matched and grabbed in a self-adapting manner, and the sectional materials are grabbed stably in the fast traction process of the sectional materials.

Description

technical field [0001] The invention relates to the technical field of metal processing, and more specifically relates to a gripping mechanism and a gripping method for drawing profiles. Background technique [0002] With the application of profiles in transportation and other fields, the quality requirements of profiles are getting higher and higher. When the profile is extruded, due to the friction between the profile rod and the extrusion die, such as the extrusion cylinder, mold, extrusion pad, etc., the flow velocity along the cross-sectional direction will be uneven during the extrusion process of the profile rod. Therefore, using a tractor to pull profile products can eliminate partial unevenness to prevent serious deformation of profile products. When traction equipment is used to improve the production quality and qualification rate of profiles, the stability of traction equipment in operation is closely related to the quality of profile production. [0003] In th...

However, when tractioning square profiles or heterogeneous profiles, the radians of the existing clip-type grippers do not match, resulting in the need to replace the corresponding grippers when tractioning profiles of different shapes or sizes, thereby greatly reducing traction The versatility and practicability of the equipment also increases the production and processing costs of the enterprise
