Description

Technical Field

[0001] The invention relates to the technical field of braided tube production, and in particular to a steel wire preforming device and a steel wire preforming method. Background Art

[0002] Hydraulic hose is an indispensable key component in the equipment manufacturing industry. It is a special ultra-high pressure, long-life wire-wound hose. Due to the high working pressure and harsh working environment, strict requirements are placed on the reliability, safety, technicality and stability of hydraulic equipment.

[0003] At present, the spindles on domestic wire braiding machines or winding machines are mainly used to provide fixed tension for the steel wire of the braided hose, but they do not have the function of pre-forming the steel wire. The hydraulic hose finally processed has excessive residual stress in the steel wire braiding layer, which causes the steel wire layer to spread out after the hydraulic hose is cut, and the inner holes at both ends will shrink and the total length will shrink, which brings difficulties to the subsequent processing and installation of pipe joints and reduces the quality of the product. Summary of the invention

[0004] In view of the above-mentioned technical problems existing in the prior art, the present invention provides a steel wire preforming device and a steel wire preforming method.

[0005] A steel wire preforming device, comprising:

[0006] A preforming seat, the preforming seat is fixedly connected to a spindle seat on the spindle device;

[0007] a preforming wheel, the preforming wheel being rotatably engaged with the preforming seat;

[0008] A preforming pin assembly is fixedly connected to the preforming seat and is located on one side of the preforming wheel.

[0009] Furthermore, the preforming seat is fixedly mounted on the wire outlet end of the spindle seat.

[0010] Further, the preformed pin assembly comprises:

[0011] A pin seat, the pin seat being fixedly connected to the preform seat;

[0012] A preformed pin is rotatably matched with the pin seat.

[0013] Furthermore, the end of the preformed pin has a retaining edge to prevent the steel wire from escaping.

[0014] Furthermore, the number of the preforming wheels is two, and a center line connecting the two preforming wheels is parallel to the axis of the preforming pin.

[0015] Furthermore, the distance between the two preforming wheels is adjustable.

[0016] A steel wire preforming method:

[0017] The first step is to install the wire preforming device, fix the preforming seat on the spindle seat by screws, and then install two preforming wheels and preforming pin assemblies in sequence;

[0018] The second step is threading. A single or multiple steel wires pass through the wire-passing wheel on the spindle in sequence, and then pass through the first preforming wheel, the preforming pin and the second preforming wheel in sequence, and the wire comes out from the second preforming wheel.

[0019] Further, the steel wire is in contact with adjacent sides of the first preforming wheel and the second preforming wheel.

[0020] Compared with the prior art, the beneficial effects of the embodiments of the present disclosure are as follows: the present disclosure sets a preforming seat, a preforming wheel and a preforming pin assembly, which form a steel wire preforming device and are installed on a spindle seat. In this way, during specific operation, after a single or multiple steel wires pass through the spindle, the required pitch can be formed by the steel wire preforming device, so that the spindle has not only the function of providing fixed tension, but also the function of steel wire preforming. The hydraulic hose finally processed can remove the residual stress of the steel wire braided layer. After the hydraulic hose is cut, the steel wire layer will not spread out, the inner holes at both ends will not shrink, and the total length will not shrink, which is convenient for subsequent processing and installation of pipe joints and improves the quality of the product.

It should also be understood that terms defined in general dictionaries, such as general dictionaries, should be interpreted as having meanings consistent with their meanings in the context of the relevant technology, and should not be interpreted in an idealized or extremely formal sense, unless explicitly defined herein.

[0033] See also Figure 1-Figure 4 , a steel wire preforming device, comprising:

[0034] A preforming seat 1, wherein the preforming seat 1 is fixedly connected to a spindle seat 4 on the spindle device;

[0035] A preforming wheel 2, wherein the preforming wheel 2 is rotatably matched with the preforming seat 1;

[0036] A preforming pin assembly 3 , wherein the preforming pin assembly 3 is fixedly connected to the preforming seat 1 and is located at one side of the preforming wheel 2 .

[0037] Specifically, the present invention provides a preforming seat 1, a preforming wheel 2 and a preforming pin assembly 3, which together form a steel wire preforming device and are installed on a spindle seat 4 of an existing spindle device. In this way, during specific work, after a single or multiple steel wires 5 pass through the spindle, the steel wire preforming device can form the pitch required for actual work, so that the spindle not only has the function of providing fixed tension, but also has the function of steel wire preforming. The hydraulic hose finally processed can remove the residual stress of the steel wire braided layer. After the hydraulic hose is cut, the steel wire layer will not spread out, the inner holes at both ends will not shrink, and the total length will not shrink, which is convenient for subsequent processing and installation of pipe joints and improves the quality of the product.

[0038] In some embodiments, the preforming seat 1 is fixedly mounted on the outlet end of the spindle seat 4 .

[0039] Specifically, the initial design plan is to install the preformed pin assembly 3 on one side of the two wire wheels at the center of the original spindle device. However, during the testing process, after the steel wire came out, the pitch formed was not ideal and did not meet the actual working requirements. The processed hydraulic hose's steel wire braided layer still had residual stress, and the steel wire layer would spread out after the hydraulic hose was cut. After many tests, the preformed seat 1 was finally installed at the outlet end of the spindle seat 4, and then the preformed wheel 2 and the preformed pin assembly 3 were installed on the preformed seat 1. In this way, the steel wire 5 is directly wound around the hydraulic hose after preforming, without any extra interference force. The forming effect is ideal and meets the actual working requirements. The hydraulic hose finally processed can remove the residual stress of the steel wire braided layer, and the steel wire layer will not spread out after the hydraulic hose is cut, the inner holes at both ends will not shrink, and the total length will not shrink, which is convenient for subsequent processing and installation of pipe joints and improves the quality of the product.

[0040] In some embodiments, the preformed pin assembly 3 comprises:

[0041] A pin seat 302, wherein the pin seat 302 is fixedly connected to the preform seat 1;

[0042] A preformed pin 301 is rotatably matched with the pin seat 302 .

[0043] Specifically, when the steel wire 5 passes through the preformed pin 301, the preformed pin 301 can rotate with the steel wire 5, thereby avoiding the friction force generated by the preformed pin 301 on the steel wire 5 and ensuring the effect of winding the hose; at the same time, Figure 4 As shown, by replacing the preformed pins 301 of different diameters, the wire 5 after being led out can have different ring diameters, thereby meeting the requirements of hoses of different diameters for the wire ring diameter.

[0044] In some embodiments, the end of the preformed pin 301 has a rib 303 to prevent the steel wire 5 from falling off.

[0045] Specifically, by providing the retaining edge 303, it is possible to prevent the steel wire 5 from being separated from the preformed pin 301 during operation, thereby ensuring normal operation.

[0046] In some embodiments, the number of the preforming wheels 2 is two, and a center line connecting the two preforming wheels 2 is parallel to the axis of the preforming pin 301 .

[0047] In some embodiments, the distance between the two preforming wheels 2 is adjustable.

[0048] Specifically, the two preforming wheels 2 include a first preforming wheel 201 and a second preforming wheel 202. Figure 2 The threading method is a schematic diagram of threading to form a positive spiral pitch. Figure 3 The threading method is a schematic diagram of threading to form a reverse spiral pitch, through the cooperation of the two preforming wheels 2 and the preforming pin 301, the circle diameter and pitch required for the work are formed, such as Figure 4 As shown, by adjusting the spacing between the two preforming wheels 2, different pitches of the steel wire can be formed, so that the wire after exiting the wire meets the coil diameter and pitch required for the work. The center line of the two preforming wheels 2 is parallel to the axis of the preforming pin 301, so that the axis of the spiral shape formed after the wire exits the wire is a straight line, that is, this method can ensure that the spiral-shaped steel wire is straight, not twisted, and ensure the quality of the final winding hose.

[0049] In some embodiments, a wire preforming method:

[0050] The first step is to install the wire preforming device, fix the preforming seat 1 on the spindle seat 4 by screws, and then install two preforming wheels 2 and a preforming pin assembly 3 in sequence;

[0051] The second step is threading. A single or multiple steel wires 5 are passed through the threading wheel on the spindle in sequence, and then passed through the first preforming wheel 201, the preforming pin 301 and the second preforming wheel 202 in sequence, and the wires are output from the second preforming wheel 202.

[0052] In some embodiments, the steel wire 5 is in contact with adjacent sides of the first pre-forming wheel 201 and the second pre-forming wheel 202 .

[0053] Specifically, the specific preforming method is to first process the installation surface, that is, to process an installation surface on the outlet end of the spindle seat 4 so as to install the steel wire preforming device, and prepare for threading after the installation is completed; when threading, multiple steel wires are a strand of steel wire, and the steel wire 5 passes through the wire wheel on the spindle device in the original way, and then passes through the first preforming wheel 201, the preforming pin 301 and the second preforming wheel 202, and the wire is output from the second preforming wheel 202. The specific routing method of the steel wire 5 is as follows Figure 2 or Figure 3 As shown, the steel wire 5 is fitted with the adjacent sides of the first preforming wheel 201 and the second preforming wheel 202, so that the force on the steel wire 5 is maximized and the forming effect is best; Figure 2 The threading method is a schematic diagram of threading to form a positive spiral pitch. Figure 3 The threading method is a threading diagram for forming a reverse spiral pitch. Different spiral directions need to be formed according to different work requirements; for example, when a braiding machine or a winding machine is winding a hose, the steel wire needs to form a positive spiral and a reverse spiral. After the steel wire 5 passes through the inner side of the first preforming wheel 201, it is sleeved on the preforming pin 301 from the outer side, and then passes through the inner side of the second preforming wheel 202, and finally exits from the second preforming wheel 202 to form a positive spiral; after the steel wire 5 passes through the inner side of the first preforming wheel 201, it is sleeved on the preforming pin 301 from the inner side, and then passes through the inner side of the second preforming wheel 202, and finally exits from the second preforming wheel 202 to form a reverse spiral.
