Trundle support punching device and punching method

Abstract

The invention discloses a trundle support punching device. The trundle support punching device comprises an upper base plate, tapered wedges, guide plates, a fixing base, punching sleeves, punching heads, inclined sliding blocks and a lower base plate, wherein the two tapered wedges are symmetrically installed, the upper ends of the tapered wedges are connected to the upper base plate, the lower ends of the tapered wedges are provided with inner slopes inclining towards the inner sides, the two inclined sliding blocks which are symmetrically installed are arranged right below the tapered wedges, the guide plates, the punching heads and the inclined sliding blocks are symmetrically installed on the left side and the right side of the fixing base from near to far respectively, when the upper base plate is pressed downwards, the tapered wedges push the two inclined sliding blocks to be both close to the middle, and the two punching heads are inserted into the two punching sleeves respectively to punch two shaft holes out. The invention further discloses a machining method for simultaneously punching the two shaft holes in movable supports at a time by utilizing the trundle support punching device. By means of the trundle support punching device and the machining method provided by the invention, the fact that the two shaft holes in the movable supports are symmetrically punched out at a time can be realized, and the hole position precision is effectively guaranteed.

Description

technical field [0001] The invention relates to a punching device, in particular to a punching device for caster brackets, which can be used for punching holes in universal caster brackets. Background technique [0002] Swivel casters are assembled from movable brackets, single wheels, etc. Such as figure 1 As shown, the two side walls 29 of the movable bracket 28 are provided with symmetrical shaft holes 30 for installing a single wheel. The position accuracy of the shaft hole 30 affects the accuracy of the movable caster after assembly. When the position accuracy of the shaft hole 30 is poor, it will cause the related facilities where the movable caster is installed to be unstable, and the shaking will tilt or even overturn when moving, affecting the normal use of the facility. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a caster bracket punching device, which can be installed on a press to punch out two ...
