Electric capacitor porcelain sleeve and case cap connecting rolling press

Abstract

The invention relates to a connecting and rolling machine of a porcelain sleeve pipe and a shell cover of a power capacitor, which mainly comprises a frame (1), a rotating, speed-reducing and transmitting system (2) of rolling wheel seats, a driving motor (3), a rolling wheel rolling-pressure transferring system (4), a rolling pressure generating device (5), a rolling pressure detecting sensor (6), a rotary rolling wheel (7), a shell cover positioning rod (8) of the capacitor and a porcelain sleeve pipe clamping device (9). The connecting and rolling machine is characterized in that the rolling pressure is transferred to the rolling wheel seats by a lever (10) through a pressure bearing (11), a sliding sleeve (13) and connecting rods (14) and (15), and the three rolling wheel seats are fixed on the connecting rod (15) and are connected with three supporting seats (17) which are evenly distributed on the circumference of a fixing piece (12) by a rotating shaft under the connecting rod (15). Compared with the prior art, the invention has the characteristics of simple structure, light weight, low cost, convenient regulation of technological parameters, and stable quality of products.

Description

Technical field: [0001] The invention relates to a mechanical processing equipment, in particular to a rolling machine for connecting a power capacitor lead wire porcelain bushing and a shell cover. Background technique: [0002] At present, the connection between domestic power capacitor lead porcelain bushing and shell is mainly based on electroless silver plating, nickel plating, and copper followed by soldering. This process has defects such as low connection strength, poor sealing performance, complex process and high production cost. There are also some attempts to solve this problem by rolling process at home and abroad, such as Chinese patent CN2863346Y, etc., but they all have the defects of bulky volume, complex structure, high energy consumption cost, cumbersome adjustment of process parameters, and unstable product quality. Invention content: [0003] Aiming at the defects of the prior art, the present invention provides a rolling machine for connecting power c...
