Abstract

The utility model discloses a plate shearing machine and belongs to the field of mechanical equipment for cutting sheet metal parts. The plate shearing machine comprises a rack, an upper tool apron and a lower tool apron, wherein an upper blade is arranged at the lower end of the upper tool apron, and a conical alloy head is disposed at the lower end of the upper blade; the upper tool apron is fixed at the upper end of the rack through a ball linear guide pair, a ball screw pair is connected to left and right ends of the upper tool apron, nuts of the ball screw pairs at the left and right ends are connected with servo motors, and the servo motors drive the ball screw pairs to control the upper tool apron; the two servo motors control the upper tool apron, so that not only can the vertically sliding distance of the upper tool apron be adjusted accurately, but also the inclination of the upper tool apron can be adjusted; the lower tool apron is arranged below the upper tool apron, a lower blade is disposed at the upper end of the lower tool apron, the lower tool apron and the upper tool apron are mutually staggered, and edge surfaces of the lower tool apron and the upper tool apron are flush with each other. According to the plate shearing machine, the hardness of the upper blade is improved, the degree of the damage to the upper blade is greatly reduced, the condemnation factor of blades is reduced, resources are saved, the working efficiency is high, labor is saved, and the accuracy of the plate shearing machine is high.

Description

A kind of plate shearing machine

Technical field

The utility model relates to the plant equipment of cutting sheet metal component, particularly relates to a kind of plate shearing machine.

Background technology

Present existing plate shearing machine, the stroke of its shearing is controlled by oil cylinder and travel switch, and control accuracy is not high, only can monoblock shear plate usually, or an end of shear material; When plates such as shearing five metals cabinet, LCD handware, often need part to shear or middle the shearing, existing plate shearing machine can't satisfy instructions for use; And plate shearing machine is the common equipment that sheet metal is sheared processing, because its target is the very big metal of hardness, so the hardness of blade and quality have high requirement, if the hardness of blade is not enough, just need often to change blade, not only waste resource, and influence operating efficiency.

The utility model content

The not high and flimsy problem of blade at the plate shearing machine precision, the utility model provides the plate shearing machine of a kind of high accuracy and the anti-consumption of blade.

Technical solution adopted in the utility model is: a kind of plate shearing machine comprises frame, upper cutter head and following tool rest; The upper cutter head lower end is provided with cutter, and the cutter lower end is provided with taper alloy head, improves the hardness of cutter, has significantly reduced the damaged condition of cutter, has reduced the scrappage of blade, has saved resource, high efficiency, and save the labour; Upper cutter head is fixed on the frame upper end by the ball line slideway auxiliary, and two ends, the upper cutter head left and right sides all are connected with ball wire bar pair, and the nut of the ball wire bar pair at two ends, the left and right sides all is connected with servomotor, thereby servomotor drives ball wire bar pair control upper cutter head; Two servomotor control upper cutter heads not only can accurately be regulated the distance that upper cutter head slides up and down, the gradient that can also regulate upper cutter head; Following tool rest is located at upper cutter head below, and following tool rest upper end is provided with bottom knife, bottom knife stagger each other with cutter and the sword face concordant mutually.

In technique scheme, the frame upper end is provided with fixed head, and servomotor is fixed on the fixed head by universal coupling, and the angular displacement of compensation servomotor makes servomotor working properly.

In technique scheme, the bottom knife top is provided with holding pad, and holding pad is erected on the frame and by vertical cylinder and drives, and holding pad is led by vertical guide pillar, and holding pad workpiece pressing when shearing workpiece prevents that workpiece is subjected to displacement.

In technique scheme, upper cutter head and following tool rest the place ahead are provided with transparent baffle, and be simple in structure but can prevent that the operator from can directly be observed operation conditions again by the flying chip bullet wound.

In technique scheme, two servomotors all are connected with controller, and controller is by stroke instruction module control servomotor, and operation accurately.

The beneficial effects of the utility model are: a kind of plate shearing machine of above-mentioned structure, by the distance that the control upper cutter head moves up and down, also just controlled the stroke that plate shearing machine is sheared; Thereby the cutting stroke of described plate shearing machine can accurately be controlled; Because cutting stroke can accurately be controlled, thereby can accurately shear plate; And blade is provided with taper alloy head, improves the hardness of cutter, significantly reduced the damaged condition of cutter, reduced the scrappage of blade, saved resource, high efficiency, and save the labour.
