Abstract
The utility model belongs to the technical field of machinery and relates to a punching machine, in particular to a locknut used in the punching machine. The locknut used in the punching machine comprises a body which is annular and provided with internal threads, and a plurality of grooves which can play the role of fixing are arranged on external surfaces of the body. The punching machine has the problem that because of punching and vibration for a long time, components are prone to looseness after a certain time, in particular to a nut used for connecting. However, the locknut used in the punching machine has the advantages that the locknut can be fixed by means of the grooves, and the looseness of the locknut in a short period can be avoided.
Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of stamping press, particularly a kind of lock nut that is used for stamping press.
Background technique
Mainly as the processing of sheet metal part, it is to utilize mould and blade processing plate to stamping press, makes workpiece generation deformation or fracture to form required shape.Stamping press utilizes stamping process one time, can get the part of complicated shape, and its finished form precision is high, specification is consistent, has the advantage of a large amount of simplification processing procedures, reduction human cost; Its principle is through the motoring flywheel, and through clutch, driving gear drives connecting rod moves up and down slide block, drives drawing die to steel plate forming.So-called two moving is exactly to refer to that press machine has two slide blocks; Be divided into inner slide and outer slide, inner slide drives the punch or the die of mould, and outer slide drives the pressed edge ring on the mould; Pressed edge ring at first moves and pushes down the steel plate edge when stretching, and inner slide moves and stretches.It is thus clear that motor and flywheel thereof are indispensable essential conditions, they have also determined the working efficiency of its stamping press simultaneously.Though widespread usage is at mechanical field for existing stamping press, its advantage also can meet the requirement of existing market, and it still exists the some shortcomings part; Especially entire machine is long-time use after, situation such as associated components is loosening appear easily, appearance loosening also mainly is because that the screw of located in connection causes under the situation of field time vibrations is loosening.
The model utility content
The purpose of the utility model technical problem to be solved is the deficiency that overcomes the above-mentioned background technology, and a kind of concrete long-pending little, with low cost, convenient install, can make compact overall structure, the effective lock nut of prevention screw loosening are provided.
The utility model has adopted technological scheme: a kind of lock nut that is used for stamping press, be arranged on the stamping press, and comprise annular and have the body of internal thread, it is characterized in that described external surface is provided with the groove that several can play fixation.
At above-mentioned a kind of lock nut that is used for stamping press, described external surface is evenly distributed with four grooves.
The beneficial effect of the utility model is: because punching press adds long-term vibrations; Situation such as loosening appear in its parts easily after the regular hour, in particular for the nut that connects, and in the present technique scheme; Realize it through groove and fix, can avoid it becoming flexible in the short time to occur.
Description of drawings
The schematic representation of Fig. 1 the utility model;
Fig. 2 is the side view of Fig. 1.
Among the figure, body 1, groove 2.
Embodiment
As illustrated in fig. 1 and 2, a kind of lock nut that is used for stamping press is arranged on the stamping press, comprises annular and has the body 1 of internal thread, and described body 1 outer surface is provided with several grooves that can play fixation 2.Described body 1 outer surface is evenly distributed with four grooves 2, is installing lock nut, only need just can realize it at groove 2 additional positioning blocks and avoid situation such as absent-mindedness.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from the spirit of the utility model or surmount the defined scope of appended claims.
Although this paper has used more term morely, do not get rid of the possibility of using other term.Using these terms only is in order to describe and explain the essence of the utility model more easily; It all is contrary with the utility model spirit being construed to any additional restriction to them.
