Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device processing equipment, and in particular to hospital guidewire processing equipment. Background Technology
[0002] Traditional methods for stripping coatings from guide wire springs include belt abrasion, sandblasting, laser stripping, and chemical stripping. However, in the field of medical guide wires, rectangular flat wires are commonly used for spring production, which presents the following problems: 1. Using chemical methods raises the issue of how to clean and remove the chemical substances, thus affecting the biosafety performance of the product; 2. Laser stripping requires the material to be stationary or relatively stationary. Stationary material affects production efficiency, while relatively stationary material requires high-precision control, which is expensive. Furthermore, the heat generated by the laser will inevitably have a certain thermal impact on the metal of the product, and the coverage area of the laser is limited, making it impossible to strip the coating on a plane perpendicular to the laser lens; 3. Belt abrasion is difficult to abrade four small planes; 4. Although sandblasting can cover four surfaces, it creates an uneven surface and makes it difficult to achieve a neat demarcation line after the coating is stripped.
[0003] The technical problem to be solved by this application is: how to design a convenient and quick structure for peeling the coating off spring raw materials. Utility Model Content
[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a quick coating stripping tool for guide wire springs.
[0005] The technical solution adopted in this utility model is as follows: a quick-peeling coating fixture for a guide wire spring, including a fixed plate, a rotating plate, a processing block, a sliding block, and a scraper. The processing block has a processing hole, the rotating plate rotates around the processing hole, the fixed plate has a limiting through hole, the rotating plate has a movable arc hole, the sliding block has a sliding shaft, the sliding shaft is fixedly connected to the sliding block, the limiting through hole and the movable arc hole are connected, the sliding shaft slides within the limiting through hole and the movable arc hole, the sliding direction of the sliding block is towards or away from the processing hole with the processing hole as the endpoint, and a scraper is fixedly provided at the end of the sliding block near the processing hole.
[0006] In some implementations, a plurality of scrapers are arranged around the machining hole.
[0007] In some implementations, adjacent scrapers are on different planes.
[0008] In some implementations, the processing block is cylindrical, and the processing hole is located at the center of the processing block.
[0009] In some embodiments, a drive assembly is included, which includes a drive element and a movable base. The output end of the drive element is connected to the movable base. The movable base is provided with a drive elongated hole, and the rotating plate is provided with a drive protrusion. The drive protrusion slides within the drive elongated hole and the extension direction of the drive elongated hole is different from the movement direction of the movable base.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] This utility model provides two technical solutions:
[0021] Example 1
[0022] Please see Figure 1 and Figure 2 A quick-peeling coating tooling for a guide wire spring includes a fixed plate 1, a rotating plate 2, a processing block 3, a sliding block 4, and a scraper 5.
[0023] The processing block 3 is fixedly mounted on the fixed plate 1. The processing block 3 has a processing hole through which the spring material passes. The rotating plate 2 rotates around the processing hole. Specifically, the processing block 3 is cylindrical, and the processing hole is located at the center of the processing block 3. The rotating plate 2 has a through hole at its center, through which the processing block 3 passes.
[0024] The sliding block 4 slides at the upper limit of the fixed plate 1. The sliding direction of the sliding block 4 is towards or away from the machining hole with the machining hole as the endpoint. A scraper 5 is fixedly installed at the end of the sliding block 4 that is close to the machining hole. The blade of the scraper 5 faces the machining hole.
[0025] The fixed plate 1 has a limiting through hole 11, the rotating plate 2 has a movable arc-shaped hole 21, and the sliding block 4 has a sliding shaft 41. The sliding shaft 41 is fixedly connected to the sliding block 4. The limiting through hole 11 and the movable arc-shaped hole 21 are connected, and the sliding shaft 41 slides within the limiting through hole 11 and the movable arc-shaped hole 21. When the rotating plate 2 rotates, the sliding block 4 moves along the movable arc-shaped hole 21 and the limiting through hole 11, and the scraper 5 moves closer to or away from the machining hole with the machining hole as its endpoint.
[0026] Please see Figure 3 In order to limit the extreme position of the sliding block 4, a limiting member 12 is provided at the end of the sliding block 4 away from the processing block 3, and the limiting member 12 is fixedly connected to the fixing plate 1.
[0027] Since the existing spring material is flat wire with a quadrilateral cross section, four scrapers 5 are arranged around the processing hole and in four directions. To avoid motion interference between the scrapers 5, adjacent scrapers 5 are on different planes.
[0028] Example 2
[0029] Please see Figure 4To enable the scraper 5 to automatically move closer to or further away from the processing hole, this embodiment preferably includes a drive assembly, which comprises a drive element 51 and a moving base 62. The drive element 51 is a motor or cylinder with linear motion at its output end. The fixed end of the drive element 51 is connected to the fixed plate 1, and the output end is connected to the moving base 62. The moving base 62 is provided with a drive elongated hole 63, and the rotating plate 2 is provided with a drive protrusion 22. The drive protrusion 22 slides within the drive elongated hole 63, and the extension direction of the drive elongated hole 63 is different from the movement direction of the moving base 62. Assuming that the extension or retraction direction of the drive element 51 is laterally, when the drive element 51 extends or retracts, the drive protrusion 22 moves in the laterally direction, thereby driving the rotating plate 2 to rotate. However, the rotation of the rotating plate 2 involves both lateral and longitudinal movements, so the drive protrusion 22 moves longitudinally within the drive elongated hole 63.
[0030] The working principle and usage process of this utility model are as follows: the spring material passes through the processing hole, the driving element 51 extends out, the scraper 5 is close to the surface of the spring material, the spring material passes through the processing hole as a whole, the driving element 51 retracts, and the coating is peeled off.
[0031] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
