Abstract

The utility model discloses a needle inserting machine without bending needles, which comprises a needle feeding mechanism, a movable knife plate, a fixed knife plate, a head support, a guide pillar, a spring, a head support fixed block, a first movable cylinder and a second movable cylinder, wherein the head support is adopted, and the head support is supported against the spring and the head support fixed plate, so that the inserting force of a clamping mechanism is kept at the elastic force level of the spring when the clamping mechanism is inserted into a needle inserting carrier, thereby ensuring the constant clamping force of the clamping mechanism, preventing the bending of the needle inserting, and reducing the difference in length caused by the resistance force of the needle inserting; the movable cutter blocks the pin hole after cutting off the wire rod, and then utilizes the second cylinder to insert the pin into the pin carrier completely, and this design has changed and has directly adopted clamping mechanism to insert the pin, then the way of directly cutting off, and such design has further guaranteed that the pin does not take place the bending, does not have the trouble of looper in the built-in again, has reduced the trouble incidence.

Description

A needle insertion machine that does not bend needles

technical field

The utility model relates to various needle insertion machines using wire materials, in particular to a needle insertion machine which does not need to bend needles inside the machine.

Background technique

In the prior art, all needle insertion machines that use wires clamp the wires through a clamping mechanism, and forcefully insert the wires into the carrier hole by cutting the knife hole. Or wear and tear will cause the needle insertion machine to bend the wire (i.e. the insertion needle) between the fixture and the cutter, and then stop the machine to troubleshoot; on the other hand, the force of insertion of the insertion needle may change due to the change of the clamping force, which may lead to changes in the length of the insertion needle. .

Utility model content

The purpose of the utility model is to provide a needle insertion machine which can ensure that the wire between the clamping mechanism and the cutter will not be bent.

The technical scheme provided by the utility model is as follows: a needle insertion machine that cannot bend needles includes:

1. Needle feeding mechanism: a device that can clamp the pin, and can work forward and return backward;

One-moving knife plate: a knife used to cut off the needle wire;

Fixed knife plate: close to the moving knife plate, there is a pin hole on it, and the pin wire of the needle feeding mechanism is inserted into the pin hole;

One butt: a plate-shaped member used to fix the pin carrier;

It is characterized in that: it also includes:

The first moving cylinder: its movable shaft is connected with the fixed block of the abutment;

The second moving cylinder: its movable shaft is fixedly connected with the cylinder body of the first moving cylinder;

An abutment fixing block: a plate-shaped member used to define the abutment and the guide post, and installed on the piston rod head of the first cylinder, with at least two positioning holes;

A spring: one end of which leans against the end surface of the abutment, and the other end abuts against the abutment fixing block;

At least two guide pillars: fixedly connected to the abutment and matched with the positioning holes on the abutment fixing block to ensure the directionality of the abutment movement;

As an improvement of the utility model, the number of the guide posts is 2;

The utility model has the following advantages: the abutment is adopted, and the design of a spring and the guide post and the abutment fixing plate is adopted behind the abutment, so that when the clamping mechanism is inserted into the pin carrier, the insertion force is kept at the elasticity of the spring force level, thereby ensuring the constant clamping force of the clamping mechanism, so that the pin does not bend, reducing the length difference caused by the resistance of the pin; after the moving cutter cuts the wire, it blocks the pin hole, and then uses The second cylinder completely inserts the pin into the pin carrier. This design changes the practice of directly inserting the pin with a clamping mechanism and then cutting it off. This design further ensures that the pin does not bend, and there is no bent pin in the machine. trouble, reducing the failure rate.

Detailed ways

Below in conjunction with accompanying drawing, specific embodiment is described:

As shown in Figure 1, a needle insertion machine that does not bend needles includes:

1. Needle feeding mechanism 1: a device that can clamp the pin, and can work forward and return backward;

A moving knife plate 2: a knife for cutting off the needle wire;

Fixed knife plate 3: close to the moving knife plate 2, there is a pin hole on it, and the pin wire of the needle feeding mechanism 1 is inserted into the pin hole;

A butt 4: a plate-shaped member for fixing and resisting the pin carrier;

The first moving cylinder 8: its movable shaft is connected with the fixed block 7;

The second moving cylinder 9: its movable shaft is fixedly connected with the cylinder block of the first moving cylinder 8;

An abutment fixing block 7: a plate-like member used to define the abutment 4 and the guide post 5, and installed on the piston rod head of the first moving cylinder 8, with at least two positioning holes;

A spring 6: sleeved outside the guide post 5, one end of which leans against the end face of the abutment 4, and the other end abuts against the abutment fixing block 7;

Two guide pillars 5: are welded on the abutment 4 and cooperate with the positioning holes on the abutment fixing block 7 to ensure the linearity of the movement direction of the abutment 4.

The action procedure is as follows: the pin carrier is fixed on the abutment 4 or the fixed knife plate 3, the movable shaft of the first moving cylinder 8 extends out and the fixed knife plate 3 clamps the pin carrier, and the needle feeding mechanism 1 clamps the pin wire , through the pin hole on the fixed knife plate 3 to feed the pin wire forward, the pin wire is inserted into the pin carrier, and at the same time it will gradually push back the head 4 and the spring 6, ensuring that the insertion force used for the pin wire is not strong will exceed the spring tension; after the head 4 retracts, the movable knife plate 2 cuts off the needle wire, and the movable knife plate 2 does not return, sealing the pin hole of the fixed knife plate 3, and the second movable cylinder 9 moves the shaft out, press the pin carrier to the fixed knife plate 3 through the first moving cylinder 8, the butt head fixing block 7 and the butt head 4, that is: push the needle against the moving knife plate 2 and insert the pin carrier, after pressing; the second The first moving cylinder 8, the second moving cylinder 9, the spring 6, and each component of the moving knife plate 2 are returned to prepare for the next cycle.
