Problems solved by technology

[0004] After the iron core falls from the iron core blanking chute, it passes through the lower mold seat and falls freely onto the material receiving and output device without recoil or shock absorption measures, and is directly conveyed out of the progressive die iron by the material receiving and output device Core, it is unavoidable to avoid the small stack of thick iron cores from falling, bruising, irregular tilting and falling

Embodiment 1

[0037] The motor core progressive die needs to realize the production of multiple stacks of thick specification iron cores in one mold. The core stack thickness value varies with customer needs, and the maximum difference can reach 60-80mm. In the mold design, the height of the blanking trough of the progressive die must meet the requirement that the maximum stacked iron core can be smoothly output from the progressive die. However, when producing the small stacked iron core, the blanking trough is too high, and the small stacked thick iron core is in the The distance of free fall in the mold increases, so that when various types of iron core output structures are used, the iron core is easy to collide with the material output device, and abnormalities such as falling, bruising, tilting and falling occur, which seriously affect the output quality of the progressive die iron core.

[0038] In the prior art, figure 2 It is the prior art progressive die iron core blanking device,...

Embodiment 2

[0050] The iron core blanking device in the above embodiment realizes the normal production of stacked iron cores of various specifications with the same set of progressive dies. The iron core blanking device in the embodiment of the present application can not only meet the functions of the above embodiment, but also satisfy Qualified blanking to the size of the iron core.

[0051] The iron core blanking device of the embodiment of the present application includes a blanking trough 1, an elastic buffer 2, a material receiving trough 4 and a lower mold base 5, the blanking trough 1 and the material receiving trough 4 are connected, and the material receiving trough 4 and the blanking trough 1 are all arranged in the lower mold base 5, so that the iron core 3 passes through the blanking groove 1 to reach the material receiving groove 4. The elastic buffer 2 is arranged on the wall of the drop chute 1 .

[0052] The elastic buffer 2 includes a buffer fixing seat 21 and a buffer...

Embodiment 3

[0060] When the iron core falls and rubs against the cushion block, it will drive the cushion block to move up and down, and the up and down movement of the cushion block affects the falling effect of the iron core. Therefore, it is necessary to improve the device on these problems. This application implements The example will improve this problem.

[0061] The elastic buffer member 2 of the embodiment of the present application is composed of an annular buffer fixing seat 21 and a buffer pad block 22. The annular buffer fixing seat 21 includes a radial channel, and an elastic bracket 23 is arranged in the radial channel. The buffer pad 22 of the embodiment of the present application is provided with a pad hanging table 221, and the pad hanging table 221 is arranged on the side of the buffer pad 22 that is away from the side where the iron core 3 falls and contacts. 221 is matched with the hanging table groove 2111, and the function between the hanging table groove 2111 and th...

Abstract

The invention relates to an iron core blanking device. The device comprises a blanking groove and an elastic buffer piece. According to the scheme, the iron core penetrates through the blanking groove and falls to the iron core bearing position, the groove wall of the blanking groove is provided with the elastic buffer part, the blanking groove and the elastic buffer part protruding on the groove wall form the blanking channel, and the size of the blanking channel is matched with the iron core, so that the iron core can exactly vertically fall and is in contact friction with the elastic buffer part; meanwhile, a guide inclined plane is arranged at one end, close to the blanking direction, of the elastic buffer piece, and plays a role in guiding and guiding, so that the iron core can be guided to the center of the blanking buffer channel, and the situation that the iron core is clamped abnormally in the falling process is avoided; and the buffering force for the iron core to directly and rapidly fall freely in the blanking groove is relieved, the abnormal quality such as falling collision damage and irregular lodging of the iron core caused by the motion of the free falling body is avoided, and the iron core can meet the standard requirement of the next procedure.
