Abstract
The invention provides a stamping method of a longitudinal V-shaped slot of a shaft workpiece. The method mainly comprises the following steps: fixing a lower clamping fixture on a punch press platform; punching a slotted hole with an upward opening and an arch section at the center of the top of the upper edge of the lower clamping fixture in the length direction, wherein the slotted hole can be in clearance fit with a workpiece, and the width of the opening of the slotted hole is equal to the designed and specified width of the V-shaped slot; arranging a baffle plate at one end of the slotted hole of the lower clamping fixture, wherein the baffle plate is used for blocking off the slotted hole; fixing the upper end of a cutter on the fixture of the punch head of the punch press, wherein the length of a cutter is the same as that of the V-shaped slot, the section of the cutting edge is the same as the designed and specified section of the V-shaped slot; and inserting the workpiece into the slotted hole from the non-closed end of the slotted hole until the top of the end props against the baffle plate, starting a punch press switch, then causing the punch head to press downwards, and causing the cutting edge to act on the workpiece to form the V-shaped slot corresponding to the cutting edge. The stamping method provided the invention has the advantages of high machining efficiency, stable quality and low cost.
Description
Technical field
The present invention relates to a kind of processing method of axial workpiece, particularly have the processing method of the axial workpiece of vertical V groove.
Background technology
As everyone knows, axle is the main parts size of plant equipment.Along with development of science and technology, the axle class that is provided with vertical V-shaped groove also increases day by day.The processing of existing vertical V-shaped groove is normally finished on milling machine, its processing method mainly is: 1, work holder is placed on the workbench of milling machine, 2, workpiece is installed in the clamping device lock, 3, start main shaft, feeding, carry out milling, 4, after milling is finished, the burr that occurs at V-type channel opening and the surperficial intersection of axle when removing milling.The weak point of above-mentioned processing method is: 1, the working (machining) efficiency of milling machine is lower, processes 1 fulcrum with 90 seconds, can only process about 320, and can not satisfy production demand in one day 8 hours; 2, tool wear is serious, needs often to change, and causes the processing cost height; 3, milling rough surface, quality instability; 4, manual deburring operation, not only efficient is low, and easily causes the surperficial bump injury of axle.
Summary of the invention:
The object of the present invention is to provide a kind of working (machining) efficiency height, steady quality, the processing method for stamping of the vertical V groove of the shaft-like workpiece that cost is low.
The present invention mainly is: establish special-purpose following mold on the punch press platform, establish dedicated tool on drift, the blade of drift acts on the workpiece, utilizes metal flow, finishes the processing of workpiece V-shaped groove.
Particular content of the present invention is as follows:
One, diel: the workpiece support mold is called for short mold down, and its bottom surface is fixed on the punch press platform by securing member.Establish opening in length greater than the length direction of the following mold upper edge top center of V-shaped groove length and be arc slotted eye to upper section, this slotted eye can cooperate with workpiece gap.The width of this slotted eye opening equals the V-shaped groove width of V-shaped groove design code.Best, above-mentioned down mold slotted eye opening both sides are the inclined-plane, and the angle on this two inclined-plane equals the angle of the V-shaped groove of design code, and this inclined-plane can be used as the tool setting basis, and cutter is installed not only accurately but also quick.In addition be provided with baffle plate with its shutoff at mold slotted eye one end down, it can be workpiece location in the insertion groove.Last mold is a cutter, and its length is identical with V-shaped groove length, and the blade cross section is identical with the V-shaped groove cross section of design code.This cutter upper end is fixed on the anchor clamps of punch press drift.Best, anchor clamps are provided with guide plate, and establishing through hole on it is pilot hole, and this pilot hole can be enclosed within on the vertical lead corresponding with it, and this lead lower end is fixed on the punch press platform.
Two, punching press: the non-blind end of workpiece from slotted eye inserted in the slotted eye, and end contacts till the baffle plate.Start the punch press switch, drift presses down, and blade acts on the workpiece, forms a V-shaped groove corresponding with blade.
The present invention compared with prior art has following advantage:
1, the formation because of groove is to finish by punching press, so surface of the work is very smooth, surface roughness can reach more than the Ra0.4, and the V-shaped groove opening does not have burr to produce, and constant product quality.
2, because of workpiece is a matched in clearance with following mold, simple to operate, quick, working (machining) efficiency is very high, whenever finishes a product and only needs for 3～5 seconds, and working (machining) efficiency improves nearly 15 times than prior art.
3, it is stressed evenly to add man-hour cutter blade, and wearability is good, and nearly 10,000 of every processing just needs reconditioning once, and the life-span has been improved nearly 25 times, and this has not only reduced processing cost, but also working continuously of having guaranteed to produce.
4, reduced manual deburring operation, not only constant product quality, and raising working (machining) efficiency.
Description of drawings:
Fig. 1 is that the master of mould of the present invention looks simplified schematic diagram.
Fig. 2 is that the A of Fig. 1 is to view.
The specific embodiment:
In the simplified schematic diagram of the processing method for stamping mould of the vertical V groove of shaft-like workpiece illustrated in figures 1 and 2, following mold 1 bottom surface is fixed on the punch press platform 2 by securing member.Establish opening in length greater than the length direction of the following mold upper edge top center of V-shaped groove length and be arc slotted eye 3 to upper section, the gap between this slotted eye and the workpiece is 0.015.The width of this slotted eye opening equals the V-shaped groove width of V-shaped groove design code.Above-mentioned mold slotted eye opening both sides down are the inclined-plane, and the angle that the angle on this two inclined-plane equals the V-shaped groove of design code is 110 °.In addition be provided with baffle plate 4 with its shutoff at mold slotted eye one end down.Cutter 5 length are identical with V-shaped groove length, and the blade cross section is identical with the V-shaped groove cross section of design code.This cutter upper end is fixed on the anchor clamps 6 of punch press drift.These anchor clamps are provided with guide plate, establish two pilot holes 7 on it, and this two pilot hole can be enclosed within on two vertical leads 8 corresponding with it, and this lead lower end is fixed on the punch press platform.The non-blind end of workpiece 9 from slotted eye inserted in the slotted eye, and end contacts till the baffle plate.Start the punch press switch, drift presses down, and blade acts on the workpiece, forms a V-shaped groove corresponding with blade.
