Abstract
The invention discloses a processing method for a hinge section steel element of a car door. The method comprises the following steps of: blanking section steel; processing steps; drilling and reaming; chamfering hole openings and tapping, wherein in the step of process steps, R in the illustration is R60mm-R120mm, and the processing machine used in the step is a machining tool; a chuck of the machining tool is fixedly provided with a disc-shaped section steel clamp; the disc-shaped section steel clamp comprises a flange, a clamp body, a pressing plate, a screw, and a shouldered nut; the clamp body fixes the section steel on the flange by a bolt; the flange is fixed on the clamp body by the pressing plate, the screw and the shouldered nut. The method provided by the invention greatly increases the quantity of workpieces clamped once, enhances the cutting speed and improves the cutting rate mainly by utilizing the machining tool flange with the characteristics of larger diameter and longer circumference (corresponding to a disc milling cutter), large rotation inertia and high linear speed.
Description
Technical field
The present invention relates to the manufacture field of body hinge shaped steel spare, concrete is a kind of processing method of body hinge shaped steel spare.
Background technology
Fig. 1 is a kind of manufacturing procedure of car side door hinge chain steel part: (1) shaped steel blanking (2) step processing (3) hole (4) aperture chamfering (5) tapping that drills and reams.Wherein operation (2) is the processing of step, and the size of diagram R is R90 ± 30mm.Prior art is that employing two diameters shown in Figure 2 are 120 ~ 180mm disk face and side cutter a Milling Process.Shortcoming: 1, process one at every turn, on average be about 10 seconds the process time of each part, can process about 2600 for one class, working (machining) efficiency is very low; 2, the cost of disk face and side cutter is higher relatively, and is every about 500 yuan; 3, the cutting kinetic energy of cutter is to provide through milling machine spindle, and the cutting noise is big, equipment and cutter loss aggravation.
Summary of the invention
The invention provides a kind of processing method of the body hinge shaped steel spare that can greatly improve working (machining) efficiency and reduce production costs.
Technical scheme of the present invention:
The processing method of body hinge shaped steel spare; Comprise following manufacturing procedure: shaped steel blanking, step processing, the hole that drills and reams, aperture chamfering, tapping; It is characterized in that: in the described step manufacturing procedure, the size of the R in the diagram is R90 ± 30mm, and the processing machine that this operation adopts is a lathe; Be installed with dish-type shaped steel anchor clamps on the chuck of lathe; Described dish-type shaped steel anchor clamps comprise ring flange, clamp body, pressing plate, screw rod, band shoulder nut, and described clamp body is installed on the described ring flange through bolt, on the described ring flange through pressing plate, screw rod and band shoulder nut fixedly shaped steel on described clamp body.
The processing method of described body hinge shaped steel spare; It is characterized in that: described pressing plate, screw rod and band shoulder nut are one group of fixation kit; A plurality of these fixation kits are installed on the described clamp body, and fixation kit is covered with and is evenly arranged in described clamp body periphery.

The specific embodiment
Referring to accompanying drawing; The processing method of body hinge shaped steel spare comprises following manufacturing procedure: shaped steel blanking, step processing, the hole that drills and reams, aperture chamfering, tapping, in the step manufacturing procedure; The size of R in the diagram is R90 ± 30mm; The processing machine that this operation adopts is a lathe, is installed with dish-type shaped steel anchor clamps on the chuck of lathe, and dish-type shaped steel anchor clamps comprise ring flange 1, clamp body 2, pressing plate 3, screw rod 4, band shoulder nut 5; Clamp body 2 is installed on the described ring flange 1 through bolt, on the ring flange 1 through pressing plate 3, screw rod 4 and band shoulder nut 5 fixedly shaped steel 6 on described clamp body 2.
On every group of fixation kit in the both sides of described screw rod 4, by pressing plate 3 fixing two shaped steel 6,10 described fixation kits are installed on the described clamp body 2, the diameter of described ring flange 1 is between the 195-205mm.
The present invention is through the pressing plate 3 in the fixation kit, screw rod 4 and band shoulder nut 5 20 of clampings even more shaped steel 6 simultaneously on clamp body 2; Utilize lathe, lathe tool 7 to process simultaneously; Improve operating efficiency greatly and solved production cost; Facts have proved process velocity by original 10 seconds 1 bring up to 60 seconds 20, working (machining) efficiency improves about more than 230%; Practice thrift about 90% (lathe tool, every about 30 ~ 50 yuan, three sword circular peripheral-mills are every 300 ~ 500 yuan) of the cost of charp tool, alleviated the extent of deterioration of equipment and cutter.
