Description

Improved Feeding Mechanism of Spring Manufacturing Machine

The utility model relates to a spring manufacturing machine, in particular to a spring manufacturing machine whose material feeding mechanism can still operate but does not feed during test run inspection.

Generally, the spring manufacturing machine is equipped with a plurality of forming tool holders on the machine table, and a wire material feeding mechanism is set on the machine table, and the wire material or plate material for making the spring is pushed in an intermittent manner by the wire material feeding mechanism, and is set by the device. A plurality of forming tool holders on the machine feed in order according to the shape of the spring to be formed, and twist the wire or plate into a coil spring or bend it into a variety of springs to be formed.

The general feeding mechanism is equipped with a sliding seat on a guide rod, and a clamping mechanism is installed on the sliding seat, and a positioning mechanism is installed on one side of the guide rod. The sliding seat is controlled by a swing rod. Drive to make it move back and forth. The swing rod is driven by an eccentric cam to drive a connecting rod. The connecting rod is pivotally connected to the proper position of the swing rod. The eccentric cam drives the swing rod to swing back and forth, so that the sliding seat can move back and forth. When the sliding seat moves forward, the clamping mechanism on the sliding seat can clamp the wire or plate and push it into the processing area of the forming tool seat, so that the wire or plate can be twisted into a coil spring or other shapes spring, and when the sliding seat moves forward to feed, the positioning mechanism is in an open state, so that the wire or plate can pass through the positioning mechanism; on the contrary, when the sliding seat moves backward, the clamping mechanism releases the wire or plate , and the positioning mechanism clamps the wire or plate, so it can be fed with equal length to make the required spring.

However, after the previous feeding mechanism starts the machine, the clamping mechanism and positioning mechanism on it start to feed the material, and this kind of spring manufacturing machine can manufacture springs of various shapes according to the needs, but every time When changing the manufactured spring, it must go through a trial run so that the prepared spring meets the requirements. If the formed knife seat or the shape of the formed knife cannot reach the required spring shape during the test run, it must be stopped for inspection or Renovation, at this time all the mechanisms must be stopped for item-by-item inspection. However, during the inspection, sometimes the feeding mechanism can be inspected without feeding materials, but all the mechanisms start again after the machine is started. , and the feeding mechanism cannot stop feeding during proofreading and adjustment, so it is more wasteful of materials during adjustment.

The purpose of this utility model is to provide a spring manufacturing machine feeding mechanism whose feeding mechanism can still act but not feed during test run inspection.

The utility model is achieved in that the feeding mechanism of the spring manufacturing machine includes a feeding mechanism, a reciprocating mechanism and a positioning mechanism, wherein:

The feeding mechanism is a sliding seat installed on a horizontally arranged slide bar, a swing clamp is pivotally arranged above the slide seat, and a spring is installed between the swing clamp and the slide seat, and the swing clamp and the slide seat A material guide hole is formed at the pivot joint between them, and a roller is pivotally arranged above the swing clamp block;

The reciprocating mechanism is installed under the slide seat of the feeding mechanism, and a swing connecting rod is pivotally connected under the slide seat, and a connecting rod is pivotally connected to a proper position on the swing connecting rod, and the connecting rod is pivotally connected on an eccentric cam;

The fixed distance mechanism is installed on the output path of the feeding mechanism. The fixed distance mechanism is composed of a drill block and a sliding clamp block, and a swing follower is arranged above the sliding clamp block;

There is also a control mechanism installed above the rollers of the swing clamp block of the feeding mechanism, and a rocker and a driven link are respectively pivoted on both sides of a guide rod, and the guide rod leans against the roller top of the swing clamp block. Another active link is equipped with a cam follower, which is driven by a plate cam, and a telescopic rod is installed between the driven link and the active link, and one end of the telescopic rod is pivotally connected to the On the driven link, the other end is worn on the active link, and a release handle is installed on the free end of the telescopic rod. The pivot end of the release handle has a long convex edge and a short convex edge. A spring is installed between the end and the active connecting rod.

The swing follower of the distance mechanism is driven by the plate cam of the control mechanism.

The utility model has the advantage that since a control mechanism is installed above the feeding mechanism, the swing clamp block of the feeding mechanism does not clamp the wire and does not feed the material by pulling the release handle on it, so it can be checked or checked. No material is wasted.

Following accompanying drawing and embodiment, will further illustrate the technical characterictic of the present utility model:

As shown in Figures 1, 2, and 3, the utility model mainly installs the following components on the machine platform:

The feeding mechanism 1 is equipped with a sliding seat 12 on a horizontally arranged slide bar 11, a swinging clamp 13 is pivotally arranged above the sliding seat 12, and a spring 14 is installed between the swinging clamping block 13 and the sliding seat 12. , and a material guide hole 15 is formed at the pivot joint between the swing clamp block 13 and the slide seat 12, and a roller 16 is pivotally arranged above the swing clamp block 13;

The reciprocating mechanism 2 is installed below the slide seat 12 of the feeding mechanism 1. The reciprocating mechanism 2 is pivotally connected with a swing connecting rod 21 under the slide seat 12, and a pivot connection is made at an appropriate position on the swing connecting rod 21. Connecting rod 22, and this connecting rod 22 is pivotally connected on an eccentric cam 23;

The control mechanism 3 is installed above the roller 16 of the swing clamp block 13 of the feeding mechanism 1, and a rocker 32 and a driven link 33 are respectively pivoted at the two ends of a guide rod 31, and the guide rod 31 leans against the swing clamp.
