Abstract

The utility model relates to a driving automatic punch press, comprising a support frame, a power mechanism, a control mechanism, a pressure head and a pressure mould, and the power mechanism is fixed on the upper part of the support frame, the power mechanism drives a spur rack whose upper end is provided with a check ring, and the lower end of the spur rack is provided with the pressure head. The check ring and a touch arm arranged on the side of the pressure head motivate the upper and lower limit switches of the control mechanism arranged on the support frame in order to control a relay and an electromagnetic switch to control the positive and negative rotation of a motor, with the upper and lower trips of the spur rack defined. One spring is arranged in the pressure head to buffer the impact force of the pressure head pressing downward, the straight compression and fracture of a terminal, which is generated because of inclined placement, is avoided. In the press mould, a push-out deflector rod is arranged and the push-out deflector rod pushes out the terminal and a winding displacement which are stitched. The utility model assures stitching quality and improves production efficiency.

Description

Driving automatic punch press

The utility model relates to positive-displacement machines, excellent and the sensitive and practical automatic positive-displacement machines of drive-type that is swift in motion of particularly a kind of pressing effect.

The conventional pressing mode of general cable terminal, be to operate fully by hand mostly, earlier terminal to be laminated is inserted in the pressing mold, winding displacement penetrates in the terminal, and the rotation manual stamping machine presses down again, with in conjunction with winding displacement and terminal, this mode is easy to generate following shortcoming: 1. fully with manual terminals of a unit block, insert behind the pressing mold again with hand punch pressing terminal, cause processing action slowly and efficient is poor, be not inconsistent economic benefit; 2. the pressure head of conventional positive-displacement machines is one-body molded blocks, inserts the position of pressing mold when inaccurate as terminal, directly impacts terminal because pressure head has buffering ground, causes terminal cracked easily, and substandard products or waste product are increased.

In view of this, the spy provides a kind of drive-type automatic positive-displacement machines, its major advantage is: 1. utilize the power of a motor as positive-displacement machines, and with floor push control motor power, the upper and lower two limit switches restriction pressure head knee-action stroke of mat controlling organization, and automatic reverse switches, make operating personnel only need be absorbed in the placement of terminal and the insertion of winding displacement, simplify the program of manual action, and reduce actuation time, improve speed of production, to meet economic benefit; 2. establish a buffering compression spring in the pressure head, mat spring force pressing terminal has a little deviation even terminal is inserted the position of pressing mold, also the unlikely pressure break terminal owing to the cushioning effect of spring; Use design,, promote its practicality to eliminate the shortcoming of prior art.
