Description

Technical Field

[0001] The present invention relates to the technical field of spring production equipment, in particular to a spring forming mechanism. Background Art

[0002] The spring is produced by bending and deforming a manganese steel wire through a guide wheel, then cutting the wire after it is processed to a certain size. When producing springs of different wire diameters, manganese steel wires of different diameters are required. Therefore, different wire supply guide wheels are required to supply and transport manganese steel wires of corresponding diameters. To address this problem, a high-speed dual-wire spring winding machine head (application number 202210713226.0) is currently available. This machine head utilizes a forming wheel that can only move linearly up and down, and a wire feed block with vertically arranged wire outlets. This allows the forming wheel to be adjusted to the manganese steel wire output from the different vertically arranged wire outlets simply by moving the forming wheel up and down linearly.

[0003] However, since the forming wheel can only move up and down, the forming wheel cannot provide lateral displacement to cooperate with the forming of the steel wire during spring forming. The forming action of the steel wire can only be achieved by moving the forming wheel up and down so that the contact points between the steel wire and the arc structure of the forming wheel are different, which is not conducive to the forming of the spring. Summary of the Invention

[0004] In view of the deficiencies of the prior art, the present invention aims to provide a spring forming mechanism in which a forming wheel can be displaced both vertically and laterally.

[0005] To achieve the above object, the present invention adopts the following technical solutions:

[0006] A spring forming mechanism, comprising a wire passing block, a forming wheel and a displacement mechanism;

[0007] A wire passing block, comprising at least two wire inlets and at least two wire outlets, all of which are arranged horizontally and vertically, and the wire outlets are connected one-to-one with the wire inlets, with each group of steel wires entering through the wire inlets and exiting from the wire outlets;

[0008] A forming wheel is provided on one side of the wire passing block provided at the wire outlet, and is used to cooperate with the steel wire forming spring at the wire outlet;

[0009] The displacement mechanism is used to drive the forming wheel to swing or slide along an arc so that the forming wheel can respectively cooperate with the steel wire output from each outlet arranged longitudinally; the displacement mechanism drives the forming wheel to move along an arc so that the forming wheel can cooperate with the steel wire at the outlet to form a forming spring.

[0010] Furthermore, the displacement mechanism drives the forming wheel to swing along an arc, so that the forming wheel can be displaced vertically to correspond to the vertically arranged wire outlets and the forming wheel can be displaced horizontally and longitudinally to cooperate with the steel wire to be formed on the forming wheel.

[0011] Furthermore, the displacement mechanism includes a swing arm and a driving device, the forming wheel is mounted on the swing arm, and the driving device is used to drive the swing arm to perform a cyclic reciprocating swinging motion.

[0012] Furthermore, the displacement mechanism drives the forming wheel to slide along an arc, so that the forming wheel 2 can be displaced vertically to correspond to the vertically arranged wire outlets and the forming wheel can be displaced horizontally and longitudinally to cooperate with the steel wire to form a spring on the forming wheel.

[0013] Furthermore, the displacement mechanism includes an arc-shaped slide rail, a slider and a driving mechanism. The slider is slidably connected to the arc-shaped slide rail. The driving mechanism drives the slider to slide back and forth along the arc-shaped slide rail. The forming wheel is installed on the slider.

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so as to provide a clearer understanding of the technical concept to be protected by the present invention.

[0020] like Figures 1 to 3 The spring forming mechanism of the present invention includes a wire passing block 1, a forming wheel 2 and a displacement mechanism 3;

[0021] A wire passing block 1, comprising at least two wire inlets 11 and at least two wire outlets 12, all of the wire inlets 11 being arranged horizontally, and all of the wire outlets 12 being arranged vertically, the wire outlets 12 being connected one-to-one with the wire inlets 11, and each group of steel wires entering through the wire inlet 11 and exiting from the wire outlet 12;

[0022] The forming wheel 2 is provided on one side of the wire passing block 1 provided at the wire outlet 12, and is used to cooperate with the steel wire forming spring at the wire outlet 12;

[0023] The displacement mechanism 3 is used to drive the forming wheel 2 to swing or slide along an arc so that the forming wheel 2 can respectively cooperate with the steel wire output from each outlet 12 arranged longitudinally; the displacement mechanism 3 drives the forming wheel 2 to displace along an arc so that the forming wheel 2 can cooperate with the steel wire at the outlet 12 to form a forming spring.

[0024] When the present application is in use, the displacement mechanism 3 drives the forming wheel 2 to swing or slide along an arc, so that the forming wheel 2 can correspond to the vertically arranged wire outlets 12 respectively, thereby ensuring that the forming wheel 2 can respectively cooperate with the steel wires output by different wire outlets 12; at the same time, when producing springs, the displacement mechanism 3 drives the forming wheel 2 to swing or slide along an arc, and can have the characteristics of lateral and vertical displacement according to the arc, so that the forming wheel 2 can approach or move away from the wire outlet 12 of the wire passing block 1 in the horizontal direction, thereby facilitating the forming of the steel wire at the forming wheel 2.

[0025] The present application provides a displacement mechanism so that the forming wheel can be displaced both up and down and left and right, thereby being able to cooperate with both the vertically arranged wire outlets and the steel wire forming.

[0026] Furthermore, the displacement mechanism 3 drives the forming wheel 2 to swing along an arc, so that the forming wheel 2 can be displaced vertically to correspond to the vertically arranged wire outlets 12 and the forming wheel 2 can be displaced horizontally and longitudinally to cooperate with the steel wire to form a spring on the forming wheel 2.

[0027] More specifically, the displacement mechanism 3 drives the forming wheel 2 to swing along an arc, which can effectively achieve vertical and lateral displacement of the forming wheel 2.

[0028] Furthermore, the displacement mechanism 3 includes a swing arm 301 and a driving device 302. The forming wheel 2 is mounted on the swing arm 301. The driving device 302 is used to drive the swing arm 302 to perform a cyclic reciprocating swinging motion.

[0029] More preferably, in one embodiment of the present application, the swing arm 302 includes a driving shaft 303 and a swing shaft 304 , and the driving device 302 is used to pull the driving shaft 303 to swing back and forth around the swing shaft 304 .

[0030] More preferably, the driving device 302 can be a cylinder, a motor crank or the like that can make a reciprocating motion, or can be other drives that can drive the swing arm 301 to make a reciprocating swing motion.

[0031] Furthermore, the displacement mechanism 3 drives the forming wheel to slide along an arc, so that the forming wheel 2 can be displaced vertically to correspond to the vertically arranged wire outlets and the forming wheel can be displaced horizontally and longitudinally to cooperate with the steel wire to form a spring on the forming wheel.

[0032] More specifically, the displacement mechanism 3 drives the forming wheel 2 to slide along an arc, which can effectively realize the vertical and lateral displacement of the forming wheel 2. At the same time, the sliding can effectively limit and observe the displacement position of the forming wheel 2.

[0033] Furthermore, the displacement mechanism 3 includes an arc-shaped slide rail 31, a slider 32 and a driving mechanism 33. The slider 32 is slidably connected to the arc-shaped slide rail 31. The driving mechanism 33 drives the slider 32 to slide back and forth along the arc-shaped slide rail 32. The forming wheel 2 is mounted on the slider 31.

[0034] More preferably, by providing an arc-shaped slide rail 31 and a slider 32 , the reciprocating motion of the forming wheel 2 is limited by the arc-shaped slide rail 31 and the slider 32 , thereby ensuring that the sliding position of the forming wheel 2 is accurate.

[0035] More preferably, the driving mechanism 33 may be a cylinder, a motor crank or the like that can make a reciprocating motion, or other driving means that can drive the slider 32 to make a reciprocating sliding motion.
