Description

Technical Field

[0001] The utility model belongs to the technical field of spring production, and particularly relates to a production device for a positioning spring hose for surgical retraction. Background Art

[0002] The forming equipment for spring production is used to produce and process springs. A spring is a mechanical part that uses elasticity to work. A part made of elastic material deforms under the action of an external force and returns to its original state after the external force is removed. According to the nature of the force, springs can be divided into tension springs, compression springs, torsion springs and bending springs. According to the shape, they can be divided into disc springs, ring springs, leaf springs, helical springs, conical scroll springs and torsion bar springs, etc. According to the manufacturing process, they can be divided into cold coiled springs and hot coiled springs. Ordinary cylindrical springs are the most widely used because they are simple to manufacture and can be made into various types according to the load conditions and have a simple structure. Generally speaking, the manufacturing materials of springs should have high elastic limit, fatigue limit, impact toughness and good heat treatment performance, etc. Commonly used ones include carbon spring steel, alloy spring steel, stainless spring steel, as well as copper alloys, nickel alloys and rubbers, etc.

[0003] Most existing spring production equipment extrudes steel wires through the equipment and then forms them by cooperating with various cutting tools. For example, a unidirectional clutch flat spring forming device disclosed in CN207255118U has a complex structure and high equipment cost. Old-fashioned equipment is difficult to adapt to the tension of the steel wire. Although its equipment is simple and has low cost, it is rarely used. Content of the Utility Model

[0024] Embodiment 1

[0025] Refer to Figures 1 to 3 , this embodiment provides a production device for a positioning spring hose for surgical traction, including a workbench 100, side supports 101 are arranged at both ends of the workbench 100, a chuck 102 is arranged on the side supports 101, a shaft rod 103 is clamped on the chuck 102, a clamping member 104 is arranged on the shaft rod 103, a guide rod 101a is fixed on the side supports 101, a lead screw 101b is also arranged on the side supports 101, a wire guiding member 105 is arranged on the guide rod 101a and the lead screw 101b, and a wire pressing member 106 is arranged on one side of the wire guiding member 105.

[0026] In this embodiment, the wire pressing member 106 is used to press down and clamp the steel wire. During the entire movement of the wire guiding member 105 along the guide rod 101a, the shaft rod 103 rotates, and the winding shape of the spring is controlled by the cooperation of the rotation speed of the shaft rod 103 and the movement speed of the wire guiding member 105.

[0027] The shaft rod 103 is clamped and fixed by a chuck.

[0028] The clamping member 104 includes an annular plate 104a. One end of the annular plate 104a is provided with a first threaded hole 104b, and a bolt 104c is screwed into the first threaded hole 104b.

[0029] A clamping rod 104d is provided on the side surface of the annular plate 104a, and the clamping rod 104d is opposite to the position of the first threaded hole 104b.

[0030] Specifically, a middle hole is provided in the middle of the annular plate 104a. The middle hole is sleeved on the shaft rod 103. The size of the shaft rod 103 is smaller than that of the middle hole. The clamping rod 104d is arranged close to the middle hole. By tightening the bolt 104c, the bolt 104c presses the shaft rod 103, so that the clamping rod 104d approaches the shaft rod 103. When in use, the end of the steel wire is placed between the clamping rod 104d and the shaft rod 103, and the bolt 104c is adjusted to clamp the steel wire.

[0031] A wire threading hole 105a is provided on the wire guiding member 105.

[0032] The steel wire is pulled from the straightening device and passes through the wire threading hole 105a.

[0033] The wire threading hole 105a is provided above the wire guiding member 105.

[0034] The wire guiding member 105 is provided with a second threaded hole 105b and a guiding hole 105c. The lead screw 101b is connected to the second threaded hole 105b, and the guide rod 101a is passed through the guiding hole 105c.

[0035] The structure of the lead screw 101b and the second threaded hole 105b is used to drive the movement of the wire guiding member 105.

[0036] The lead screw 101b is connected to a stepping motor.

[0037] The wire pressing member 106 includes a frame rod 106a axially connected to the wire guiding member 105. A spring 106b is provided below the frame rod 106a and connected to the wire guiding member 105.

[0038] A lead wire wheel 106c is rotatably connected to the frame rod 106a, and a lead wire groove 106d is provided on the lead wire wheel 106c.

[0039] A pressing wheel 106e is rotatably connected to the end of the frame rod 106a, and a pressing groove 106f is provided on the pressing wheel 106e.

[0040] Further, the steel wire passes through the wire threading hole 105a, winds around the wire guiding groove 106d on the upper side of the wire guiding wheel 106c and reaches the pressing groove 106f on the lower side of the pressing wheel 106e. Under the action of the spring 106b, the end of the support rod 106a presses downwards. One end of the steel wire winds around the shaft rod 103, and the support rod 106a presses down and straightens the steel wire.

[0041] It should be understood that in the development process of any actual implementation, such as in any engineering or design project, a large number of specific implementation decisions can be made. Such development efforts may be complex and time-consuming, but for those of ordinary skill in the art who benefit from this disclosure, without undue experimentation, such development efforts will be routine work of design, manufacturing, and production.

[0042] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them.
