Problems solved by technology

[0006] The disadvantages of this production method are: low production efficiency and high labor intensity; both the semi-finished terminal and the semi-finished electric arm brush have scraps, resulting in a reduction in material utilization; It is difficult to guarantee the stability of the molding and angle of each product; the sweat stains left by manual riveting can easily oxidize the surface of the product; at the same time, manual riveting will also cause poor riveting, misalignment, and insufficient pull-off force due to inaccurate positioning and other defects

Embodiment 1

[0025] With reference to Fig. 2a-Fig. 2e, comprise the following steps:

[0026] Referring to Fig. 2a, the brass strip 20 used to make the terminal is installed in the terminal feeding guide rail on the worktable, and the beryllium copper strip 21 used to make the elastic arm is installed in the elastic arm feeding guide rail on the workbench at the same time , the two guide rails can be at an angle of 10°-90° and intersect. The choice of the angle can be based on the size of the material. What this embodiment uses is that the brass material strip 20 is located in the transverse direction of the workbench, and the beryllium copper material strip 21 is located on the workbench. The longitudinal direction, the two form an angle of 90 degrees, and a riveting stamping die is provided at the intersection of the two;

[0027] Referring to Fig. 2 b, before the brass strip 20 and the beryllium copper strip 21 move to the riveting stamping die, the brass strip 20 and the beryllium copp...

Embodiment 2

[0030] Embodiment 2, with reference to Fig. 3, for wider beryllium copper strip 21, can make the beryllium copper strip 21 of elastic arm and the brass strip 20 of making terminal form an angle of 45 degrees, all the other are the same as embodiment 1.

Abstract

The present invention discloses a producing method for a direct current motor carbon brush rack, which adopts the producing method combined the automatic feeding of a brass material belt and a beryllium copper material belt and automatic punching of a terminator produced by the brass material belt and an elastic arm produced by the beryllium copper material belt, thereby replacing the separate molding of the terminator and the elastic arm, manual riveting and further completing molding, falling and other working sequences for the riveted terminator and the elastic arm in the prior art. The present invention has the advantages of high producing efficiency, stable combination of the terminator and the elastic arm, guaranteed quality, reduction of corner material and improved operation factor of raw material.

Description

technical field [0001] The invention relates to a production method of a carbon brush holder, in particular to a production method of a DC motor carbon brush holder. Background technique [0002] In the prior art, the production method of the DC motor carbon brush holder generally includes the following steps, referring to Fig. 1a-Fig. 1c: [0003] 1. The brass strip is automatically punched into a semi-finished terminal 10 by using a mold that produces multiple products in one mold, and a number of bumps 11 are punched out on the semi-finished terminal 10; [0004] 2. The beryllium copper strip is automatically stamped into a semi-finished elastic arm 12 by using a mold that produces multiple products in one mold, and the semi-finished elastic arm 12 has a number of holes 13; [0005] 3. The semi-finished terminal 10 and the semi-finished spring arm 12 are riveted into the finished carbon brush holder 1 by manual riveting with a special jig. [0006] The disadvantages of ...
