Continuous deep drawing device, sheet nut stamping parts manufacturing equipment and manufacturing method

Abstract

The invention provides a continuous deep-drawing device, preparation equipment and a manufacturing method for punched parts of thin-plate nuts. Wherein, the continuous drawing device includes a die mechanism located above the conveying path, a die mechanism positioned below the conveying path, and a first driving mechanism that drives the two mechanisms to approach or move away from the blank at the same time. A plurality of punches with decreasing outer diameters and increasing lengths are sequentially arranged on the die mechanism along the conveying path, and grooves with inner diameters and heights larger than the outer diameter of the punches are respectively arranged at positions corresponding to the plurality of punches on the die mechanism. , when the die mechanism and the die mechanism are close to the blank at the same time, the punch punches the blank into the groove; the thin plate nut punching parts manufacturing equipment has a coil cutting device, a conveying device, a continuous deep drawing device, an upsetting leveling device, Punching device and control device.

Description

technical field [0001] The invention belongs to the field of thin plate nut preparation, and in particular relates to a continuous drawing device, thin plate nut stamping parts manufacturing equipment and a manufacturing method. Background technique [0002] In the integrally formed thin-plate nut, the thin-plate part and the nut part are integrally formed, and there is no solder joint at the transition part between the thin plate and the nut, and the transition is smooth, which can better match other parts of the car at the use part. At present, integrally formed thin plate nuts are gradually replacing traditional fasteners and are used for fixing key components such as engines, gearboxes, chassis suspension components, longitudinal beams and door locks in automobiles. [0003] The traditional method of preparing integrally formed sheet nuts is as follows: (1) sheet cutting, cutting the sheet into square pieces of a certain size; (2) deep drawing, placing the square piece b...

AI Technical Summary

Problems solved by technology

[0005] Since each deep-drawing process is carried out on a separate cold extrusion device, the preparation of thin-plate nut intermediates by this deep-drawing method is not only costly, time-consuming, and occupies a large area of ​​processing equipment; In the method, the processing deviation of each cold extrusion device is different. With the progress of the processing process, the deviation gradually accumulates in the blank, which is easy to cause uneven wall thickness of the drawn part. After the subsequent tapping process, the deviation of the thread is large , so that thin plate nuts are not suitable for occasions requiring high thread accuracy

Moreover, since it is very difficult to control the processing deviation of each cold extrusion device to be exactly the same, it is difficult to further improve the wall thickness uniformity of the drawn part by using the method of the prior art
