Description

Technical Field

[0001] The utility model relates to the technical field of commutator production, in particular to a forming die used in a commutator pressing and forming process. Background Art

[0002] At present, the production and processing methods of commutators are mainly divided into three types: insert type, roll type (copper plate type) and full plastic type. The three processing methods each have their own advantages and disadvantages. The production and processing process route of the insert type commutator is: copper material extrusion → drawing → punching commutator → vibration cleaning → (punching mica sheet) → sheet arrangement → pressing and forming → curing → boring → back hole → turning the outer circle and boring the inner hook foot → milling the lower engraving → milling the hook foot → bending the hook into shape → polishing → inspection. The pressing and forming is mainly divided into three steps: entering the circle, product pressing and forming, and demolding.

[0025] The utility model provides a technical solution:

[0026] Embodiment 1

[0027] Combination Figures 1 to 4 A forming mold for a commutator pressing process includes a mold body 3, a frame plate 4 is arranged on the left and right sides of the mold body 3, a base 5 is fixedly connected to the bottom of the frame plate 4, a fixing mechanism 1 is arranged inside the frame plate 4, and a pre-support mechanism 2 is arranged on the top of the base 5.

[0030] Furthermore: the staff only needs to pass the bolt 1103 through the frame plate 4 and thread it into the convex plate 1101 to complete the fixation of the mold body 3 and the frame plate 4. The operation is simple and convenient for the staff to disassemble and assemble the mold body 3, so that the staff can replace different types of molds according to usage needs. At the same time, the limiting slide plate 1201 slides downward to limit the installed limiting slide plate 1201, so that the installed limiting slide plate 1201 cannot move outward by itself, thereby increasing the stability of the mold body 3 after installation.

[0031] Embodiment 2

[0032] See also Figure 1 , Figure 2 , Figure 3 and Figure 5 On the basis of the first embodiment, it is further obtained that the pre-support mechanism 2 includes a support component 21, a telescopic component 22 and a limit component 23, the support component 21 is arranged at the top of the base 5 and below the fixed component 11, the telescopic component 22 is arranged at the bottom of the support component 21, and the limit component 23 is arranged in the telescopic component 22.

[0033] The support assembly 21 includes a support pad 2101, which is arranged below the convex plate 1101. A compression spring 2102 is fixedly connected to the bottom of the support pad 2101. The compression spring 2102 is fixedly connected to the top of the base 5. A limit plate 2103 is arranged above the compression spring 2102. The limit plate 2103 is fixedly connected to the front and rear sides of the convex edge 1102. The telescopic assembly 22 includes a telescopic slide 2201, which is fixedly connected to the bottom of the support pad 2101. The inner ring of the telescopic slide 2201 is slidably connected with a fixed slide rod 2202, and the fixed slide rod 2202 is fixedly connected to the top of the base 5. The limit assembly 23 includes a limit slider 2301, and the limit slider 2301 is fixedly connected to the front and rear sides of the fixed slide rod 2202. The limit slider 2301 is slidably connected to the front and rear sides of the telescopic slide 2201. The outer side of the limit slider 2301 is fixedly connected to a limit sleeve 2302, and the inner side of the limit sleeve 2302 fits with the outer ring of the telescopic slide 2201.

[0034] Furthermore: before the bolt 1103 is connected to the protruding plate 1101, the support pad 2101 moves upward under the action of the compression spring 2102 and contacts the bottom of the protruding plate 1101 to complete the support of the mold body 3, thereby reducing the force required for the staff to manually support the mold body 3 and reducing the work intensity of the staff.

[0035] In actual operation, when this device is used and the mold body 3 needs to be installed, the staff first presses the support pads 2101 on the left and right sides to move downward, and then the staff moves the mold body 3 to move the convex plate 1101 to the position above the support pads 2101, and then the staff releases the pressure on the support pads 2101. At this time, the support pads 2101 on the left and right sides, under the action of the compression springs 2102, drive the support pads 2101 upward to contact the bottom of the convex plate 1101 to complete the support of the convex plate 1101, and then the staff moves the mold body 3 upward to make the convex plate The top of 1101 contacts the bottom of the convex edge 1102, and then the staff pulls the left and right side handles 1204 to move upward, and the handles 1204 move upward through the inlay plate 1203 to drive the limiting slide 1201 to move upward. After the limiting slide 1201 moves upward, the staff passes the bolt 1103 through the top of the frame plate 4 to make it contact with the outer side of the convex plate 1101, and then rotates the bolt 1103. The bolt 1103 rotates in the convex plate 1101 and moves inward. After the bolt 1103 is installed, the staff moves the limiting slide 1201 downward, and the installation of the mold body 3 is completed at this time.
