Description

Motor case assembly manufacturing apparatus and method {A MANUFACTURING APPARATUS FOR MOTOR-CASE ASSEMBLY AND METHORD}

The present invention relates to the manufacture of a motor case assembly, and in particular, to significantly reduce the production equipment, to be produced automatically and continuously to reduce the production cost, to ensure the safety of the operator of the motor case assembly manufacturing apparatus of a small motor And to a method.

The motor case assembly of a small motor, which is mounted on the lower part of the car seat mainly for adjusting the height, angle and front and rear positions of the car seat, is composed of a combination of the motor case and the cover.

The conventional motor case assembly of a small motor was made by pressing the motor case and the cover into separate molds, and then transporting them to another place to insert the cover into the motor case, and then completed the first crimping and the second crimping.

1 is a flow chart showing a manufacturing process of the above-described conventional motor case manufacturing technology, Figure 2 is a process flow diagram schematically showing a manufacturing process process according to the prior art.

As shown in FIG. 1 and FIG. 2. The prior art described above, in manufacturing one motor case assembly 2,

The motor case 10 is manufactured through a case fabrication press machine 210 including a mold in which notching and piercing 211 and a bending process 212 sequentially cut and extract a product from a workpiece,

In addition, after the cover is manufactured through a cover manufacturing press machine 220 including a mold in which the notching 221, the drawing 222, and the notching 223 are sequentially processed,

After the motor case 10 and the cover 20 are transported to a separate assembly crimping place, the cover 20 is inserted into the case 10 and passed through the first crimping press 230.

Again, the motor case assembly 2 is completed and taken out through the second pressing press 240 for finishing molding.

In the conventional motor case assembly manufacturing technology, as described above, four sets of molds and four presses that operate one by one set in each process are largely passed through four processes, and waste of equipment cost is enormous. There was a problem that efficient factory operation could not be achieved due to excessive storage space and spot area.

In addition, since the case and the cover are press-processed at different places in the process, the product is moved to another place for assembly crimping and subsequent processes are continued. As a result, the waste of labor and work time is large, and thus, efficient production is not achieved and production costs are increased.

Meanwhile, each motor case and cover manufactured in different places are moved to another place, and the first pressing process is performed after the cover is inserted into the press machine by the operator, and the subsequent process is also carried by the worker's hand. In the process of putting into the second pressing press, the accident of the worker by the press was frequent and difficult.

The present invention has been made to solve the above problems,

An object of the present invention is to provide an apparatus and method for manufacturing a compact motor case assembly,

The motor case assembly is completed by allowing the motor case and cover to be manufactured in parallel in the mold apparatus operated in one press machine, and the subsequent process for assembling and joining such as inserting and crimping the motor case and cover is continuously performed automatically. By reducing the production equipment, the cost is significantly reduced and the space of the factory is efficiently operated. The production of the product is efficient, so that the mass production is easy, and the manufacturing cost is significantly reduced. An economical motor case assembly manufacturing apparatus and method for preventing a safety accident are provided.

As shown in Figure 3 and 4, the motor case assembly manufacturing apparatus 1 of the preferred embodiment of the present invention,

First line 110, which is a motor case manufacturing mold for forming the motor case 10 by sequentially performing notching, piercing, and bending processing on the workpiece,

The second line 120, which is a cover manufacturing mold for forming the cover 20 by sequentially performing primary notching, drawing, secondary notching, right angle bending, and blanking for the workpiece,

A conveying means 130 which is automatically transferred to insert and compress the cover 20 manufactured in the second line 120 into the motor case 10 of the first line,

The cover 20 transferred through the transfer means 130 is inserted into the motor case and pressed through the first pressing mold 141, and then pressed secondarily through the second pressing mold 142 for finishing. Afterwards, the third line 140 located on the extension line of the first line 110 to automatically perform the process of cutting and separating the product from the workpiece with the blanking mold 143 is automatically performed in one press machine. The motor case assembly manufacturing method according to the present invention is as follows.

In the first step, the motor case manufacturing mold of the first line 110 automatically transfers a workpiece of a predetermined length by a feeder, which is a workpiece feeder that is separately attached to a press machine, thereby providing a process for the motor case processed material 10a. Through the notching and piercing processing 111 through the progressive press to make the expanded shape of the motor case 10, the bending 112 is bent in a round shape close to the cylindrical,

At this time, the motor case body is not completely separated from the workpiece 10a, and is processed while a part is connected.

In the second step, the cover manufacturing mold installed in parallel with the first line in the second step, the range of the material to be drawn by the primary notching processing 121 for the cover processing material 20a, which is also automatically transferred by the feeder, is determined. , Forming a convex portion of the cover in the drawing processing 122, and completes the edge shape of the cover in the secondary notching processing 123, and covers the cover 20 formed in the right angle bending process 124 cover material (20a) The cover 20 is completed at a right angle with respect to the cover material 20a by a blanking process 125.

At the same time, the cover material swatches separated from the product in the second line are continuously transported and discharged.
