Steel plate punching device capable of automatically replacing punch

Abstract

The invention discloses a steel plate punching device capable of automatically replacing a punch. The device comprises a mounting table and a shell. In the device, a rotating shaft, a rotating plate,a sleeve and an ejector rod are utilized, when the punch needs to be replaced, a servo motor drives a driving gear to rotate for a certain number of turns, the driving gear drives a driven gear to rotate for a certain number of turns, and the driven gear drives the rotating shaft to rotate for a certain number of turns, so that the sleeve with different punches is moved to the portion under the ejector rod, a cylinder shrinks, an ejector plate is driven to move downwards quickly, then the ejector rod is driven to move downwards quickly, then a push head is driven to push a sliding block to move downwards, the sliding block moves downwards to drive a guide rod to contract, a punch rod drives the punch to punch a steel plate, a worker controls the rotation angle of the servo motor through aPLC, and then the sleeve with different punches can be switched and rotated to the portion under the push head during work for automatically switching the punches and complete punching. The automationdegree is high, the device is convenient to use, and the punching efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of stamping machinery, in particular to a steel plate punching device for automatically replacing punches. Background technique [0002] Stamping is to rely on presses and molds to apply external force to plates, strips, pipes and profiles, etc., to cause plastic deformation or separation, so as to obtain workpieces (stamping parts) of required shape and size. Stamping and forging belong to Plastic processing (or pressure processing), collectively known as forging, stamping blanks are mainly hot-rolled and cold-rolled steel plates and steel strips, 60-70% of the world's steel products are plates, most of which are made by stamping Finished products, automobile body, chassis, fuel tank, radiator, boiler steam drum, container casing, motor, electrical iron core silicon steel sheet, etc. are all stamped. Instruments, household appliances, bicycles, office machinery, There are also a large number of stamping pa...

Problems solved by technology

[0003] The current stamping equipment is complex and diverse, with complete functions and a high degree of automation. When the plate is stamped, different holes need to be opened on the surface of the plate. At this time, different punches are required for stamping. The traditional method is to use an assembly line for stamping. , requires repeated positioning and installation, and the punching operation of the plate cannot be completed in one installation. The punching process is complicated and the punching cost is high. At the same time, the traditional punching equipment needs to manually replace the punching head. Replacing the punching head is time-consuming and labor-intensive, which delays the production time and affects the production efficiency. Therefore, a mechanical device that can automatically replace the punching head and complete the plate punching with one installation is needed to solve the above problems.
