Bending machine head for straight spring framework

Abstract

The invention discloses a bending machine head for a straight spring framework and belongs to the field of manufacturing equipment. The bending machine head comprises a fixed disc, a guide cylinder with a wire passing channel in the center is arranged on a front end surface of the fixed disc, circular T-shaped grooves are formed in the end surface of the fixed disc, a plurality of fixed blocks ofwhich upper surfaces are provided with sliding rails are fixed on the T-shaped grooves, sliding blocks driven by a hydraulic cylinder are arranged on the sliding rails, the fixed disc is connected with a bending device, a clamping device and a cutting device through the sliding blocks, the bending device comprises a motor fixed to a sliding block, a driving disc is connected to an end of the motor, a reference column is fixed to the center of the driving disc, a torsion column with the adjustable distance between the torsion column and the reference column is arranged on the end face, the clamping device comprises two clamping blocks fixed to two opposite sliding blocks, the cutting device comprises a cutter fixed to a sliding block, and the motion trail of the cutter is located on an endface of the guide cylinder. The machining efficiency and the product quality are improved, and machining of steel wires with different diameters and straight springs with different bending radians ismet.

Description

technical field [0001] The invention relates to the field of manufacturing equipment, in particular to a straight spring bending equipment. Background technique [0002] A large number of straight springs are needed in car seats. A straight spring is a structure in which both ends of a steel wire are bent downwards and then bent inwards until they contact the horizontal steel wires. See image 3 As shown, so in order to meet the needs of car seats, it is necessary to bend wires of different diameters. The traditional processing method is mostly to measure the size and mark the position, and then manually add tools to assist in the production, which is time-consuming and laborious, and the dimensional accuracy cannot be guaranteed. In view of the deficiencies of manual bending, there have been forming machines that can automatically bend wires. Existing steel wire bending equipment generally includes a control mechanism, a transmission mechanism, a wire feeding mechanism and...
