Multifunctional forming cutter of high-precision automobile condenser fixing flange liquid storage tank

Abstract

The invention relates to the technical field of machining tools, in particular to a multifunctional forming cutter of a high-precision automobile condenser fixing flange liquid storage tank. The multifunctional forming cutter comprises a cutter base body, wherein a forming chamfer blade is arranged at the front end of the cutter base body, a transition cutter bar is arranged at the center of the front end of the cutter base body, a drill reaming cutting part is arranged at one end of the transition cutter bar, the drill reaming cutting part comprises a reamer part, a pre-drilling bit is arranged at the front end of the reamer part, and a reverse chamfer blade is arranged at the tail end of the reamer part. According to the multifunctional forming cutter of the high-precision automobile condenser fixing flange liquid storage tank, the pre-drilling bit positioned at the forefront end of a cutter is used for drilling so as to remove most of the allowance, so that the subsequent cutting pressure of the reamer part is relieved, the abrasion of the cutter of the reamer part is reduced, and the final machining quality of a reamed hole is guaranteed; and the drilling, the reaming, the reverse chamfering and the front high-precision hole surface forming can be completed only through one-time clamping and one cutter, being efficient and rapid.

Description

technical field [0001] The invention relates to the technical field of machining tools, in particular to a high-precision multifunctional forming tool for fixing flange liquid storage tanks of automobile condensers. Background technique [0002] In the process of the existing machining center for the quick installation and sealing holes of parts such as liquid storage tanks and pressure plate joints on high-end cars, it is necessary to use various tools in the tool magazine to respectively realize drilling, reaming, chamfering, and end cutting. Forming and other processing techniques have complex processing steps; the cost of stocking tools and handles is high; and sometimes because of insufficient tool positions, the process has to divide the parts that were originally processed in one process into two or more processes; replacement The tool is cumbersome and needs to waste a lot of time to perform invalid repetitive actions to replace the tool, and each time the tool is re...

Problems solved by technology

[0003] In order to overcome the shortcomings of the existing workpiece hole processing technology complex and high tool cost, the invention provides a high-precision automobile condenser fixed flange liquid storage tank multifunctional forming knife, through the pre-drilling on the cutting part of the drilling reaming The hole drill bit drills the workpiece deeply, and then the reamer at the rear end of the pre-drilling bit reams the pre-hole drilled. After the drilling and reaming cutting part penetrates the entire workpiece to form a through hole, then the machining center controls The tool performs circular interpolation around the hole and then controls the reverse chamfering edge to perform chamfering operations on the reverse side of the hole, and then the tool returns to the center to process and shape the hole through the forming chamfering edge
