Abstract

The utility model belongs to the technical field of spring processing equipment, particularly the structural improvement of a screw pitch control mechanism of a spring forming machine, which is composed of a screw pitch cam, a swing arm, a lever and a screw pitch push rod, wherein the screw pitch cam is arranged on a cutter shaft and contacts a roller which is arranged on the swing arm; one end of the swing arm is connected with a machine body, and the other end of the swing arm is connected with the upper end of the lever; a pivot of the lever is movably fixed on the machine body; the lower end of the lever and the lower end of the screw pitch push rod are clamped on a screw pitch control mechanism of a spring forming machine of the screw pitch push rod. The utility model realizes single cam control, and has the advantages of simple mechanism, cost saving, stable running, no movement and deviation and high work efficiency. The utility model does not need to be detected and adjusted often.

Description

The structural improvement of spring forming machine propeller pitch control system

Technical field:

The utility model relates to the spring technical field of processing equipment, refers in particular to a kind of structural improvement of spring forming machine propeller pitch control system.

Background technology:

Spring is as one of the most basic machine components, and it all has a wide range of applications in the every field of national economy and social life.Along with socioeconomic continuous development, its demand is also in continuous increase.Just because of this, people are also more and more higher for the requirement of the spring forming machine that the production spring is used, the spring forming machine has been done the trial of various improvement for improving its production efficiency, be included in its wire agency, cutter mechanism, aspects such as external diameter controlling organization have all obtained bigger progress, but on the propeller pitch control system of spring forming machine, but can not get bigger breakthrough for a long time, the propeller pitch control system of traditional spring forming machine adopts in two cam combination controls, the incision cutter shaft, existing operation steadily often occurs moving with deviation therefore needing to detect often and adjust in the middle of the course of work inadequately, product is inconsistent before and after causing, not only had a strong impact on operating efficiency, also can cause the generation of more substandard products, both waste resource, increased production cost again.

The utility model content:

The purpose of this utility model is, at above problem, by improving existing technology, provides a kind of structural improvement of simple in structure, the easy to operate and spring forming machine propeller pitch control system that precision is high.

For achieving the above object, the utility model adopts following technical scheme: the utility model mainly comprises: pitch cam, rocking arm, lever, pitch push rod.The pitch cam is installed on the slitter shaft and contacts with roller on being installed in rocking arm, and an end of rocking arm is connected on the body, and the other end is connected the upper end of lever, and the fulcrum activity of lever is fixed on the body, and the lower end is then blocked and withstood on the pitch push rod.

Pitch push rod recited above is " Y " font, and disposes linear bearing at its each end.

Pitch recited above is installed on the upper cutter axle apart from cam.

Pitch recited above is installed on the incision cutter shaft apart from cam.

The beneficial effects of the utility model are: adopted the pitch cam; rocking arm; lever; the pitch push rod is formed; the pitch cam is fixed on the slitter shaft and contacts with roller on being installed in rocking arm; an end of rocking arm is connected on the body; the other end is connected the upper end of lever; the fulcrum activity of lever is fixed on the body; the propeller pitch control system of the spring forming machine that withstands on the pitch push rod is then blocked in the lower end; realized single cam control; make mechanism simpler; both to save cost, make operation more steady again, and can not occur moving and deviation; need not detect often and adjust, improved operating efficiency greatly.

Description of drawings:

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

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the side view of accompanying drawing 1.

The specific embodiment:

See that the utility model mainly comprises shown in accompanying drawing 1, the accompanying drawing 2: pitch cam 1, rocking arm 2, lever 3, pitch push rod 4.Pitch cam 1 is installed on the slitter shaft and contacts with roller 5 on being installed in rocking arm 2, and an end of rocking arm 2 is connected on the body, and the other end is connected the upper end of lever 3, and the fulcrum activity of lever 3 is fixed on the body, and the lower end is then blocked and withstood on the pitch push rod 4.

Pitch push rod 4 recited above is " Y " font, and disposes linear bearing 6 at its each end.

Pitch recited above can be installed on the upper cutter axle apart from cam 1, is used to control negater spring pitch this moment.

Pitch recited above also can be installed on the incision cutter shaft apart from 1 cam, is used to control dextrorotation spring pitch this moment.

When pitch cam 1 is installed in the upper cutter axle, the servo motor driven slitter shaft rotates, thereby driving coaxial pitch cam 1 rotates, pitch cam 1 by be installed in roller 5 contact actions on the rocking arm 2 in rocking arm 2, thereby rocking arm 2 again the lever 3 control pitch push rods 4 by control and pitch push rod 4 Ka Ding make it to release corresponding stroke and finally realized control pitch.

Certainly, the embodiment of the above, it is preferred embodiments of the present utility model, be not to limit the utility model practical range, so all equivalences of doing according to the described structure of the utility model claim, feature and principle change or modify, and all should be included in the utility model claim.
