Abstract

(57) [Summary] [Purpose] In order to cut the wire rod B for wire mesh into an arbitrary fixed size, an arbitrary stopper 10 attached to the measuring rod 1 is lowered to the wire running path A, and the tip of the wire rod B is pushed forward. Although cutting is performed by a shearing blade C, the movement of the measuring rod 1 is made easier, and the stopper 10 is prevented from being bent by eccentric pressure of the driving body 1. [Structure] The drive body 2 is not only a pressurizing body as in the past, but also a reciprocating drive body, and the conventional return spring is eliminated. The engagement portion between the drive body 2 and the stopper 10 is composed of a rectangular plate 11 with an elongated hole, a pair of rolling elements 12, and a bifurcated member 13.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention relates to a wire cutting device for wire mesh.

0002

[Conventional technology]

The present applicant has proposed ``Continuous Measurement Cutting Apparatus for Wire Rods'' in Japanese Utility Model Application No. 63-7406. To briefly explain this with reference to FIG. 4, the wire B is fed into the running path A, and when its tip hits the stopper 10 protruding downward from the measuring rod 1, the measuring rod 1 also begins to move together, and the rear part of the measuring rod It is cut by a shearing blade C while running. In the figure, a wire B having a length L ₃ is obtained, but this is immediately removed from the running path A. Since the moved measuring stick 1 compresses the spring 4, the movement of automatically returning to its original position due to the reaction force of the spring 4 is repeated.

0003 The prior proposal shown in FIG. 4 does not attach the driving body 2 that pushes down the stopper 10 to the measuring rod 1, The device was fixed in the machine frame 6, which does not move. Until then, the conventional device had each driving body on the measuring rod 1 itself. Because it was attached, measuring rod 1 became heavy and did not move easily.

0004

[Problem that the idea aims to solve]

The previous proposal mentioned above made the measuring stick 1 move more easily than previous devices, but it took a long time. During use, the movement of the measuring stick 1 and stopper 10 became slow. sharpen this As a result of the investigation, as in the embodiment shown in FIG. The engaging portion is a rolling engagement between the pressure roller 7 and the pressure receiving plate 8, and the fluid pressure that is the driving body is If the cylinder is reset by the spring 9 as before, all the driving bodies 2 are always Since the driving body 2 presses the pressure receiving plate 8 and particularly lowers the stopper 10, it applies a strong pressure. The lightness of the measuring stick 1 is reduced by that amount, and the piston of the fluid pressure cylinder is restored. Since the spring 9 is compressed with sufficient strength to By moving the length bar 1, a bending moment is applied to the stopper 10, and the stopper is gradually moved during use. We clarified that this is because the P10 curves and becomes difficult to move, and based on this clarification, we This idea was developed in pursuit of an improvement measure.

[Means to solve the problem]

The wire rod cutting device for wire mesh of this invention has a measuring rod at several locations along the wire running path. A stopper is provided to penetrate the length rod and allow the tip to go in and out of the above-mentioned running path, so that the rod can be continuously fed. When the tip of the wire rod hits one of the above stoppers, the measuring rod will move along with the wire rod. In the device that runs and cuts the wire with the shear blade at the rear of the measuring rod, The stoppers of the measuring sticks above are each pushed by each driving body fixed at the corresponding position on the machine frame. It is possible to enter and exit the wire rod entry path by pulling out and pulling back, and each of the above driving bodies and each stopper The engaging part is a rectangular plate with a long hole along the wire running path, and a bifurcated part that sandwiches this rectangular plate. It consists of a bifurcated member that pivotally supports a pair of rolling elements in the elongated hole at regular intervals. It is characterized by.

[0006]

[Effect]

The previous proposal shown in Figure 4 was based on the drive body (hydraulic cylinder) attached to the measuring rod 1 itself. The return spring 9, which was commonly used as a means of returning after pressing down, is used as is. However, this invention eliminates this and both pushing out and pulling back the stopper 10 are driven. I let my body do what it did. This eliminates the biggest cause of the problems mentioned above, and also The engagement part between the drive body and each stopper is made of a rectangular plate with an elongated hole and a pair of rolling elements inside the elongated hole. It is constructed with a bifurcated member that supports the body, so simply hold the stopper in the down position. The bending moment that bends the stopper cannot be generated with a pressing force that is large enough to bend the stopper. Ta.

【Example】

Figure 1 shows an example of this invention compared to the previous proposal (Figure 4), and the parts with the same function are Indicated by the same symbol. As before, the wire runs through the measuring rod 1 at several locations along the wire running path A. A stopper 10 is provided to move the lower end into and out of the wire A, and the end of the wire B is continuously fed. When it hits one of the stoppers 10, the measuring rod 1 begins to move together with the wire B, This is a device that runs and cuts the wire B using a shearing blade C at the rear of the measuring rod.

[0008] One of the two points in which this invention differs from previous proposals is that each stopper 10 of the measuring rod 1 is driven. In order to Not only that, but it also has a pullback drive, eliminating the need for the conventional return spring 9. It is a point. Another point is that the engagement portion between the drive body 2 and the stopper 10 has been improved as follows. It is.

[0009] That is, the upper end of the stopper 10 has a rectangular hole 11a along the wire running path A. The plate 11 is fixed, and the lower end of the rod of the reciprocating hydraulic cylinder that is the driving body 2 has an upper A pair of rolling elements (in this case In this case, a bifurcated member 13 that pivotally supports the roller) 12 at regular intervals was fixed.

0010 In this way, the driving body 2 and the stopper 10 are connected to a pair of rolling elements 12 and the rolling elements 1. Since the wire rod B is engaged with the rectangular plate 11 with an elongated hole that receives the wire rod B, the wire rod B , the measuring stick 1 placed on the guide roller 3, each stopper 10 and its rectangular plate 11 are Even when moving to the chain line position in Fig. 1, a bending moment large enough to bend the stopper 10 is generated. do not have.

[0011] Figures 1 and 2 are explanatory diagrams compared with Figure 4, and Figure 3 is a plan view for manufacturing this invention. The wire running path A is located in the slot of the semi-tubular measuring rod 1'. And stopper 10 is The measuring rod 1' faces the running path A from the left and right, and the driving bodies 2 are also located on both sides. This diagram 3, the wire B is omitted and only the arrow in the direction of entry is shown. Since the wire rod running path A is placed inside the measuring rod 1', the wire rod can be guided and stopped reliably. Since the stoppers 10 are provided on both the left and right sides, more types of wire lengths can be obtained. Ru. Note that this invention is not limited to the above two embodiments, and can be modified in various ways without changing its gist. Ru.

[Effect of the idea]

This invention is different from the conventional design when realizing the idea of the above-mentioned invention which is currently being applied for by the present applicant. We will solve the reason why problems occur when the fluid pressure cylinder, which is the main driving body, is returned to its spring state. I made it clear. We developed a configuration that would not cause any problems.

[0013] In other words, the drive body that drives the stopper should be a reciprocating drive body that does not require a return spring. Therefore, it does not pressurize the stopper, but simply holds it in position. This eliminates the aforementioned problems caused by pressurization. And the engagement part between the drive body and the stopper Since it is a combination of a rectangular plate with a long hole, a pair of rollers, and a bifurcated member, the measuring stick Even if the stopper moves, the stopper holding action by the driving body remains unchanged, and the bending by the spring Moment no longer occurs.
