Abstract

The utility model discloses an improved coarse wire diameter spring machine, which comprises a wire feeding mechanism, a cutting mechanism, and an external diameter control mechanism; wherein, the external diameter control mechanism comprises an external diameter shaft for mounting an external diameter control cam, and two locking posts for bending wire materials are arranged on the end face of the external diameter shaft. During primary wire mounting, wire runs out, and wires break, steel wires can be directly mounted in the wire feeding wheel and the wire clamp of the wire feeding mechanism, the front ends of the steel wires are delivered to the space between the two locking posts of the external diameter shaft by computer, according to the desired spring size, the external diameter shaft is rotated at a corresponding angle, that is, the front ends of the steel wires are pre-bent into arc-shaped, thereby being very convenient and having high work efficiency. In addition, a wind shaft can also be added at one side of the external diameter shaft, so that the wind shaft is rotated and performs reciprocation movement, so as to reach the same function as the wind shaft of the torsion spring machine, thereby realizing the multiple purposes by only one unit.

Description

The thick line diameter spring machine of improvement

Technical field:

The utility model relates to the coiling machine technical field, especially relates to a kind of coiling machine that is used to produce the thick line diameter spring.

Background technology:

The coiling machine that is used to produce spring at present just during the wiring material, generally adopts manual mode that steel wire is wound into suitable circular shape in advance at the accent machine.This mode is for the thick line footpath wire rod of diameter more than 3mm, if the pitch of the laps external diameter is too small, because the bending strength of steel wire is very high, manual pitch of the laps not only labour intensity is very big, inefficiency, and also abnormally dangerous.

In addition, the function of present coiling machine (as pressure spring machine) is comparatively single, can only produce same class spring, can't reach effect of one machine multiple purposes, causes the idle waste of equipment.

The utility model content:

The purpose of this utility model is the weak point that exists at prior art and a kind of thick line diameter spring machine of improvement is provided, and it can just during the wiring material, be reeled to steel wire automatically in advance at the accent machine; In addition, it also can be used for torque spring except can be used for stage clip production, realizes a tractor serves several purposes.

For achieving the above object, the utility model includes wire agency, cutter mechanism, external diameter controlling organization, wherein, the external diameter controlling organization has one and is used to the outside journal axle that external diameter is controlled cam is installed, and the end face of described outside journal axle is provided with two screens posts that are used to bend wire rod.

As improvement of the technical scheme, side at outside journal axle, also be provided with a wireline reel parallel with outside journal axle, pass through gears engaged between described wireline reel rear end and the outside journal axle, row one bearing holder (housing, cover) is established at its middle part, and bearing holder (housing, cover) is fixed with oscillating bearing on the outer face, and this oscillating bearing cooperates with the chute at lever middle part, the middle part of lever and a support are hinged, and the rear end then cooperates with the pitch push rod.

After adopting technique scheme, the beneficial effects of the utility model are: at the first wiring material and when running on line, the pitch of the laps lambda line that breaks again machine of accent machine, can directly be contained in steel wire in the Wire Wheel and wire clamp of wire agency, by computer control the steel wire front end is delivered between two screens posts on the outside journal axle, according to needed spring size, make outside journal axle rotate corresponding angle, can be bent into the steel wire front end circular-arc in advance, very convenient, operating efficiency is very high.In addition, after outside journal axle one side installs wireline reel additional, outside journal axle can drive the wireline reel rotation, simultaneously, the pitch push rod then back and forth moves forward and backward wireline reel by lever, reaches the function the same with the wireline reel of torsion spring machine, thereby realizes the purpose of a tractor serves several purposes, change traditional pressure spring machine and can only produce the unicity of stage clip, had good business efficiency.

Description of drawings:

Below in conjunction with accompanying drawing the utility model is described further:

Accompanying drawing 1 is an overall structure schematic diagram of the present utility model;

Accompanying drawing 2 is one of outside journal axle user mode figure of the present utility model;

Accompanying drawing 3 is two of outside journal axle user mode figure of the present utility model;

Accompanying drawing 4 is three of outside journal axle user mode figure of the present utility model;

Accompanying drawing 5 is the transmission principle figure of outside journal axle of the present utility model, wireline reel and lever.

The specific embodiment:

The following stated only is preferred embodiment of the present utility model, does not therefore limit protection domain of the present utility model.

See shown in the accompanying drawing 1: coiling machine of the present utility model includes wire agency 10, cutter mechanism 20, external diameter controlling organization 30 and (also has some other mechanism certainly, here repeat no more), wherein, external diameter controlling organization 30 has one and is used to the outside journal axle 31 that external diameter is controlled cam is installed, and outside journal axle 31 end faces are provided with two screens posts 32 that are used to bend wire rod.See that accompanying drawing 2 is to shown in the accompanying drawing 4: coiling machine is when the thick wiring material of accent machine, can directly be contained in steel wire 100 in the Wire Wheel and wire clamp of wire agency 10, by computer control steel wire 100 front ends are delivered between two screens posts 32 on the outside journal axle 31, according to needed spring size, make outside journal axle 32 rotate corresponding angle, steel wire 100 front ends can be bent in advance circular-arcly, afterwards, steel wire 100 returns to and carries out coiling and molding on the coiling and molding position.

See shown in the accompanying drawing 5: in the side of outside journal axle 31 near wire agency 10, also be provided with a wireline reel 41 parallel with outside journal axle 31, mesh by gear 411,311 between wireline reel 41 rear ends and the outside journal axle 31, the tool middle part is provided with a bearing holder (housing, cover) 412, bearing holder (housing, cover) is fixed with oscillating bearing 413 on 412 outer faces, this oscillating bearing 413 cooperates with the chute 421 at a lever 42 middle parts, and the middle part of lever 42 and a support 43 are hinged, and the rear end cooperates with pitch push rod 44.Like this, after driven by motor outside journal axle 31 rotates, wireline reel 41 is with outside journal axle 31 rotations, simultaneously, pitch push rod 44 by lever 43 wireline reel 41 is done back and forth to move forward and backward (operation principle of pitch push rod 44 can consult application before me " structural improvement of spring forming machine propeller pitch control system; Granted publication number is: CN 2832349Y); the wireline reel that is equivalent to the torque spring machine is the same; thus make coiling machine except can producing compression spring and wire rod; also can be used for producing torque spring, reach effect of one machine multiple purposes.And when not needing to produce torque spring and wire bracket, the meshing gear on outside journal axle 31 and the wireline reel 41 311,411 can be removed again, and lever 43 is removed, at this moment, wireline reel 41 is motionless, can recover the duty of compression spring machine.
