Description

Seat lever manufacturing equipment for automobiles

The present invention relates to an apparatus for manufacturing a seat lever for a vehicle, and more particularly, to improve the precision of the shaft pipe process and the press process, which are core processes in manufacturing the seat lever, and to simultaneously perform the shaft pipe process and the press process, resulting in productivity It relates to an apparatus for manufacturing a seat lever for a vehicle that can increase the

In general, the operation method of a car seat is divided into an electric type and a manual type, and in general, a manual operation type car seat is divided into three motions: vertical movement, backrest angle adjustment, and horizontal movement, and each has a separate lever.

Among them, the height adjustment lever and the backrest angle adjustment lever are made of plastic on the side of the seat, and the horizontal adjustment lever is a steel pipe shape and is placed at the lower front of the seat, and its official name is CONN PIPE TRACK LEVER.

Although most manufacturers are focusing on the development of electric-powered seats recently, they are only being applied as an option or option in some luxury segments, and the manual operation method of the seat forms various sales countries or customer groups by car model. It is a method that is necessary to be applied.

This can be seen only by looking at the vehicle specification table of the most recently released domestic parent company. Specifically, in the case of a passenger car, it is applied to the driver's and passenger seats that require front and rear adjustment, and in the case of an SUV, it is also applied to the first-row seat and the second-row seat that can be adjusted. becomes this

In addition, the manual method is more advantageous than the electric method for reducing the weight of automobiles, and there is still a large demand for the manual method for export models.

On the other hand, the automobile seat industry is continuously growing under the influence of advanced products and future technology development, and the manual seat lever field, which can be said to be a rear industry related to seat manufacturing, also has a stable demand structure.

However, as the global economy worsens recently, exports are sluggish and overall finished car production is decreasing, which is directly affecting the domestic auto parts manufacturing industry. They are facing a crisis due to rising manufacturing costs, and are having difficulties in generating profits even with a fixed production volume.

Here, the conventional method for manufacturing the lever of the seat for a car is largely a shaft pipe process and a press forming process, and in more detail, the raw material, which is a pipe, is cut to the required size, and the cut material is put into the shaft pipe equipment to both ends. It consists of three steps: shaft pipe work and a final shape using a press forming machine. Among them, the core process is the shaft pipe process and the press forming process.

However, in this conventional method of manufacturing a lever for a seat for an automobile, the shaft pipe process and the press forming process are separated from each other, so that an additional production loss of moving and storing the material (the lever before molding) occurs, and the manpower caused by the difference in the process time There is a problem of lowering management efficiency.

In addition, since the shaft pipe process and the press forming process are separated, separate facilities are used for each process. In order to perform the shaft pipe, dedicated equipment must be used, and a press facility of at least 100 tons must be used in the forming process. However, due to the characteristics of the press facility, the area occupied by the press is large, and the space efficiency is low, such as dead space occurring due to movement between processes. In addition, additional manpower, time, and cost are consumed by the use of separate equipment to move materials.

On the other hand, the conventional device used for the shaft pipe process of the seat lever for a vehicle is a hydraulic system, and it requires a pump and a tank, which are power sources, so space efficiency is inevitably reduced, and it is difficult to control the precise position and speed, so it is difficult to manage dimensions. Because hydraulic oil is used, there is an environmental problem due to this.

In addition, due to the nature of the hydraulic system, it is difficult to completely remove the leakage, so when the surrounding environment becomes dirty during long-term use, additional costs, time and manpower are inevitably consumed for maintenance. Accordingly, it is inevitable that the operator will have the trouble of calibrating the equipment.
