Definitions
- the invention relates to a method and a device for producing stamped parts, in particular lamellae.
- Stamped parts in particular lamellae, as are used, for example, as a clutch or brake in automatic transmissions, are usually produced in the following process steps: stamping, deburring, straightening and visual inspection.
- punching the workpiece is punched out of the raw material.
- stamped burrs are formed on the outer and inner contours. These burrs are removed during deburring.
- Deburring processes include belt grinding, brushing and surface grinding.
- straightening the workpiece is brought to a specifiable flatness, for example by rolling.
- the last step in the procedure is the visual inspection. During the visual inspection, the workpiece is checked for damage, such as scratches or impressions. Between these individual process steps, the workpiece is removed from the respective tool, stored temporarily and transported to the next tool.
- the process steps can be reduced to punching, deburring and visual inspection.
- One type of pretreatment is, for example, relaxation annealing.
- the disadvantage of this known manufacturing method is the high manufacturing effort and the long manufacturing time.
- the object of the invention is to reduce the manufacturing outlay and the manufacturing time.
- the task is solved by a method for producing stamped parts, in particular lamellae, in which case the method comprises only two method steps.
- a first method step the workpiece is punched out of raw material in a device in a cutting stage and, after the punching, is brought into a pre-punching step by means of transfer pliers likewise accommodated in the device.
- the Prague stage is also within the device.
- the inner and outer contours are stamped on the workpiece in the workede stage, so that the burrs formed on the workpiece in the first process step are rounded.
- the solution according to the invention offers the advantage that the workpiece is produced in only one tool. A post-treatment and visual inspection are not necessary. Another advantage is that intermediate storage and transportation are also eliminated.
- a first workpiece be punched from raw material during a working step in the cutting stage and that the burrs are stamped out in the second stage in the pre-cutting stage.
- the first workpiece is automatically transported from the cutting stage to the verye stage by means of the transfer pliers.
- the second workpiece is removed from the device at the same time and the fineblanking stage is equipped with a new raw material.
- Reference number 1 shows the device.
- the device 1 consists of a fine blanking stage 2, a transport tongs 4 and the embossing stage 3.
- the workpiece 5 is punched from raw material.
- the workpiece 5 is designed as a lamella in cross section.
- circumferential stamped burrs 6 are produced on the lamella 5 both on the inner and on the outer contour. In this state, the lamella 5 cannot be used without aftertreatment.
- the slat 5 is ejected from the fineblanking stage 2 into one
- Transfer tongs 4 pressed.
- the transfer tongs 4 automatically transport the finely-cut lamella 5 into the embossing step 3 within the device 1.
- the burrs of the lamella 5 are stamped, in other words, the outer and inner contours of the lamella 5 is rounded. This is shown in FIG. 1 with the reference number 7.
- the embossing stage 3 consists of an upper die part 8 and a lower die part 9. The lamella 5 produced in this way is ready for installation without any further operations.
- a higher number of machined workpieces is achieved by simultaneously processing a first lamella in the fineblanking stage 2 and a second lamella within the embossing stage 3 during one operation. After completion of this work step, the first lamella is brought out of the fine blanking stage 3, as described above, in the embossing stage 3. At the same time, the second lamella, finished in step 3, is removed from the tool.
- this method and the device is not limited to the manufacture of lamellae.
- the method and the device can generally be used for the production of stamped parts.
