Description

Technical Field

[0001] This utility model relates to the field of iron chip stamping tools, and in particular to an automatic iron chip pressing device. Background Technology

[0002] Iron chips are a major component of the stator and rotor of a motor. They need to be stamped into a single unit for subsequent installation of the winding coil. Existing automatic iron chip pressing devices mainly consist of a stamping device, an upper die, and a lower die. However, during the stamping process, individual iron chips need to be stacked. The outer ring of the iron chip has grooves, and the inner ring has multiple equidistant winding holes. During stacking, misalignment frequently occurs, causing the winding holes and grooves to malfunction. Furthermore, the lack of limiting measures during stamping alters the stacking position of the iron chips. After stamping, the iron chips are inside the lower die, making them difficult to remove and hindering subsequent stamping operations. Therefore, solutions to these technical problems are needed.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: In this utility model, by opening a stacking groove in the shape of the iron chip in the lower mold, it is convenient for the iron chips to be uniformly aligned and stacked. By passing the positioning rod through the winding hole of the iron chip, it is convenient to restrict the position of the iron chip so that misalignment will not occur during stamping. Through the cooperation of the telescopic rod and the demolding seat, it is convenient to push out the stamped iron chip and facilitate the next stamping. In the end, it solves the problems of iron chip stacking misalignment, lack of restriction of the position of iron chip during stamping, and inconvenience in removing the stamped iron chip.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Example: See Figure 1-5This utility model discloses an automatic iron chip pressing device, comprising a main body 1, which is U-shaped in shape. A hydraulic cylinder 2 is vertically mounted on the top surface of the front end of the main body 1, and the piston rod of the hydraulic cylinder 2 passes through the upper end of the main body 1. An upper mold 3 is mounted on the lower end of the piston rod. The bottom surface of the upper mold 3 is provided with a stamping boss in the shape of an iron chip in the middle. Guide rods 4 are vertically and equidistantly mounted at four ends of the bottom surface of the upper mold 3. Multiple equidistant positioning rods 5 are provided between the multiple guide rods 4. One end of the positioning rod 5 is fixedly connected to the stamping boss. The U-shaped structure of the main body 1 facilitates the separation of the upper mold 3 and the lower mold 6. The piston rod of the hydraulic cylinder 2 facilitates the up-and-down movement of the upper mold 3. The guide rods 4 facilitate the merging of the upper mold 3 and the lower mold 6. The positioning rods 5 facilitate the passing through the stacked iron chips to align the iron chips. The stamping boss facilitates the stamping of the iron chips into a whole.

[0019] In this utility model, multiple support columns 7 are vertically and equidistantly installed on the worktable surface of the main body 1. A lower mold 6 is horizontally installed on the upper end of the support columns 7. A chip stacking groove is opened in the middle of the top surface of the lower mold 6, and a demolding groove is opened in the middle of the bottom surface, which penetrates through the stacking groove. Guide holes are opened at four equidistant ends in the middle of the top surface of the lower mold 6. A demolding seat 8 is vertically installed at the lower end of the lower mold 6. The upper end of the demolding seat 8 penetrates through the demolding groove and is level with the stacking groove. A telescopic rod 9 is provided at the lower end of the demolding seat 8. The telescopic rod 9 is secretly hung in the middle of the worktable surface of the main body 1, and the output shaft of the telescopic rod 9 is fixedly connected to the demolding seat 8. The chip stacking groove in the middle of the lower mold 6 facilitates the stacking of chips. The support columns 7 facilitate the fixing and support of the lower mold 6. The demolding seat 8 facilitates the ejection of the stamped chips. The telescopic rod 9 facilitates the raising or lowering of the demolding seat 8.

[0020] Working principle: When using this utility model, firstly, iron chips are placed one by one into the stacking groove of the lower mold 6, and the shape and position of the iron chips are adjusted in time to align with the shape of the stacking groove. When the iron chips are stacked to a certain height, the switch button is pressed, and the piston rod of the hydraulic cylinder 2 moves down to push the upper mold 3 and the lower mold 6 to merge. The guide rod 4 passes through the guide hole of the lower mold 6 to facilitate the alignment of the upper mold 3 and the lower mold 6. The positioning rod 5 passes through the winding hole in the middle of the iron chip to align the iron chip again. The merging of the upper mold 3 and the lower mold 6 facilitates the stamping boss to stamp the stacked iron chips into a whole. After the stamping is completed, the piston rod of the hydraulic cylinder 2 moves up, and the upper mold 3 and the lower mold 6 separate. The ejector seat 8 and the telescopic rod 9 facilitate the ejection of the stamped iron chips for the next stamping.
