Blank wedge block side ejection structure with effectively lengthened stroke

Abstract

The invention discloses a blank material wedge block side ejection structure with an effectively lengthened stroke. The blank material wedge block side ejection structure comprises push assemblies. Alocking assembly is arranged at the front end of each push assembly. An ejection assembly is arranged on one side of each locking assembly. Each locking assembly comprises a second installation base,a second guide sleeve, a wedge rod and a push rod. Each second guide sleeve is arranged on the corresponding second installation base in a sleeving manner. Each wedge rod is connected in the corresponding second guide sleeve in an inserted manner and connected with the corresponding push assembly and penetrates through a square hole of the corresponding push rod. One side of each wedge rod is a first inclined face with a self-locking angle. The push rods stretch into the second guide sleeves. A second inclined face abutting against the corresponding first inclined face is arranged in each square hole, and the other end of each wedge rod is connected with the corresponding ejection assembly. An ejector rod is arranged in each ejection assembly and connected with the corresponding push rod through a connecting shaft, the wedge rods are driven to stretch out and draw back through the push assemblies, and then the push rods are pushed to drive the ejector rods to do linear reciprocating motion. The blank material wedge block side ejection structure is long in effective stroke, the ejection point is close to a saw kerf, the deformation force of blank materials is effectively overcome, the minimum width of the blank material is small, the equipment failure rate is low, and the service life of a saw blade is long.

Description

technical field [0001] The invention relates to the technical field of cutting equipment, in particular to a side top structure of a sub-material wedge with an effectively lengthened stroke. Background technique [0002] When the circular saw cuts the steel plate, the internal stress will change sharply and have no direction, which will cause irregular deformation of the saw kerf, resulting in the phenomenon of knife clamping. The usual method is: 1. Install an oil cylinder on the side of the sub-material, and install a pressure block at the front end of the piston rod of the oil cylinder to directly press the side of the sub-material to prevent the sub-material from deforming towards the master material. However, the internal stress of the steel plate is very large, and The pressure of the oil cylinder is constant, and the internal stress of the deformation of the sub-material is often greater than the pressing force of the oil cylinder, and there is a large gap between the...

Problems solved by technology

[0002] In the process of sawing the steel plate with the circular saw, the internal stress will change sharply and have no direction, which will cause irregular deformation of the saw kerf, resulting in the phenomenon of knife clamping

The usual method is: 1. Install an oil cylinder on the side of the sub-material, and install a pressure block at the front end of the piston rod of the oil cylinder to directly press the side of the sub-material to prevent the sub-material from deforming towards the master material. However, the internal stress of the steel plate is very large, and The pressure of the oil cylinder is constant, and the internal stress of the deformation of the sub-material is often greater than the pressing force of the oil cylinder, and there is a large gap between the piston rod and the pressure block of the oil cylinder, which is difficult to prevent the deformation of the sub-material. Second, use a hydraulic wedge side jacking mechanism. This mechanism uses an oil cylinder to push the wedge against the side of the sub-material, and uses the self-locking and good guiding rigidity of the wedge to effectively prevent the sub-material from deforming toward the master material. However, the steel plate The sides are mostly rough, and the size changes greatly, but the effective stroke of this mechanism is relatively short, and it often cannot reach the side of the steel plate, which brings great inconvenience to loading and feeding. Moreover, the mechanism is close to the steel plate, and the volume The wedge rod is long, in order to avoid interference with the saw blade, the ejector rod is far away from the saw kerf, and the jacking effect is affected
