Description

Technical Field

[0001] The utility model relates to the technical field of PTFE thermal curing equipment, in particular to a thermal curing tooling for medical guide wires. Background Art

[0002] According to the curing requirements of PTFE products, the PTFE products need to be placed in a curing tooling for thermal curing. For example, for medical guide wires, currently a blast drying oven is used for thermal curing of medical guide wires. On the one hand, the blast drying oven has a slow heating rate. After opening the door, it takes at least half an hour for the temperature inside the oven to drop to a level where it will not scald the human body so that the product can be taken out, which is time-consuming and has low efficiency. On the other hand, some medical guide wire products are relatively long and cannot be directly placed into the blast drying oven. If the medical guide wire is bent, it is easy to cause poor curing at the bent part of the medical guide wire, resulting in defective products. Summary of the Utility Model

[0003] For this reason, an object of the utility model is to provide a thermal curing tooling for medical guide wires to solve the problems mentioned in the background art and overcome the deficiencies in the prior art.

[0004] To achieve the above object, the utility model adopts the following technical solutions:

[0005] A thermal curing tooling for medical guide wires includes a heat insulation cover and a frame. A first thermal curing component is arranged inside the heat insulation cover, and a second thermal curing component is arranged on the frame. The first thermal curing component and the second thermal curing component are arranged opposite to each other. The heat insulation cover is composed of several third heat insulation plates. The first thermal curing component is connected to the heat insulation cover. The heat insulation cover is connected with rollers through connecting pieces. A guide rail is arranged on the frame, and the rollers are connected to the guide rail.

[0006] Furthermore, the heat insulation cover is connected with a bracket, and a telescopic cylinder is arranged on the bracket. The heat insulation cover can move along the direction of the guide rail under the drive of the telescopic cylinder.

[0007] Furthermore, the first thermal curing component includes a first heating plate and a first heat insulation plate. A first heating tube is arranged on one side of the first heating plate, and the first heating plate and the first heat insulation plate clamp the first heating tube in the middle.

[0008] Furthermore, the second thermal curing component includes a second heating plate and a second heat insulation plate. A second heating tube is arranged on one side of the second heating plate, and the second heating plate and the second heat insulation plate clamp the second heating tube in the middle.

[0009] Further, there are several first heating plates, and the several first heating plates are connected in sequence and arranged longitudinally. The number of the first heat insulation plates is the same as that of the first heating plates, and the several first heat insulation plates are connected in sequence and arranged longitudinally.

[0010] Further, there are several second heating plates, and the several second heating plates are connected in sequence and arranged longitudinally. The number of the second heat insulation plates is the same as that of the second heating plates, and the several second heat insulation plates are connected in sequence and arranged longitudinally.

[0011] Further, the second heat curing assembly is connected with several fixing pieces, and there are two brackets and two telescopic cylinders respectively.

[0012] Further, the frame includes several cross beams and several support columns. The several cross beams surround a rectangle. One end of the several support columns is connected to the cross beams, and the other end of the several support columns is connected with casters.

[0013] Therefore, the present utility model has the following beneficial effects:

[0014] For a medical guide wire heat curing tooling of the present utility model, when the telescopic cylinder retracts backward, the heat insulation cover moves backward to make the heat insulation cover in an open state. When the coated medical catheter enters the curing device, the telescopic cylinder extends forward at this time, and the heat insulation cover moves forward to cover the coated PTFE product. The first heat curing assembly and the second heat curing assembly perform heating, and the coated medical catheter product is heat cured at a temperature of 400 °C. When the heat curing time is reached, the telescopic cylinder retracts backward again, the heat insulation cover moves backward, and the heat cured product is taken out. The heat insulation cover closes again to ensure the temperature inside the heat curing device, and the PTFE product is heat cured.

[0015] By curing the medical guide wire through the heat curing tooling of the present utility model, the heat curing tooling has a fast heating rate, can be continuously produced, does not have the problem of waiting for the cyclic heating and cooling of the blast drying oven, has a high production efficiency, and the heat curing tooling is set for the medical guide wire, and the length of the heat curing assembly is relatively long, meeting the requirements of the long PTFE product and the need for high-temperature curing.

[0029] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present utility model, and should not be construed as a limitation to the present utility model.

[0030] In the present invention, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", "fix" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] like Figures 1 - 10 As shown, a medical guidewire heat curing tooling comprises a heat insulation cover 1 and a frame 2, a first heat curing component 3 is arranged in the heat insulation cover 1, a second heat curing component 4 is arranged on the frame 2, the first heat curing component 3 and the second heat curing component 4 are arranged opposite to each other, the heat insulation cover 1 is composed of a plurality of third heat insulation boards 16, the first heat curing component 3 is connected to the heat insulation cover 1, the heat insulation cover 1 is connected to a roller 6 through a connecting piece 5, a guide rail 7 is arranged on the frame 2, and the roller 6 is connected to the guide rail 7.

[0032] The heat insulation cover 1 plays a role of heat insulation to prevent heat loss and ensure the temperature inside the thermal device. When the heat insulation cover 1 is closed, the heat insulation cover 1 is buckled on the second heat curing component 4, and the first heat curing component 3 is located in the heat insulation cover 1. A certain gap is left between the first heat curing component 3 and the second heat curing component 4 for placing PTFE products (medical guide wires) for high-temperature curing.

[0033] like Figure 1 and Figure 2 As shown, further, the heat insulation cover 1 is connected to a bracket 8, and a telescopic cylinder 9 is provided on the bracket 8. The heat insulation cover 1 can move along the direction of the guide rail 7 under the drive of the telescopic cylinder 9.

[0034] It can be understood that the telescopic cylinder 9 is provided with a telescopic rod, which is connected to other device structures or fixed objects as the fulcrum of the telescopic cylinder 9. When the telescopic rod of the telescopic cylinder 9 is extended forward, the heat insulation cover 1 moves forward to cover the PTFE product. When the telescopic rod of the telescopic cylinder 9 is extended backward, the heat insulation cover 1 moves backward to open, so that the heat-cured PTFE product can be taken out.

[0035] The telescopic cylinder 9 belongs to the existing mature technology, and the specific structure of the telescopic cylinder 9 will not be described in detail here.

[0036] Further, such as Figure 5 , Figure 6 , Figure 7 and Figure 9 As shown, the first thermal curing assembly 3 includes a first heating plate 10 and a first heat insulating plate 11. A first heating tube 12 is provided on one side of the first heating plate 10. The first heating plate 10 and the first heat insulating plate 11 clamp the first heating tube 12 in the middle.

[0037] As an implementation manner, the first heating tube 12 can be an electric heating tube, and a resistance wire is arranged inside the tube. When powered on, the resistance wire generates heat and transfers the heat to the heating plate to perform high-temperature curing on the PTFE product.

[0038] As an implementation manner, the first heating tube 12 can also be a liquid pipeline. The heat medium is heated by a heating device outside and then flows into the heating tube, transferring the heat to the heating plate to perform high-temperature curing on the PTFE product.

[0039] As an implementation manner, the shape of the first heating tube 12 is serpentine, and the first heating tube 12 is attached to the surface of the first heating plate 10 and evenly distributed.

[0040] Furthermore, as shown in Figure 5 , Figure 6 , Figure 7 and Figure 8 , the second thermal curing component 4 includes a second heating plate 13 and a second heat insulation plate 14. A second heating tube 15 is arranged on one side of the second heating plate 13, and the second heating plate 13 and the second heat insulation plate 14 clamp the second heating tube 15 in the middle.

[0041] The second heating tube 15 has the same structure as the first heating tube 12, and will not be elaborated here.

[0042] Furthermore, as shown in Figure 6 , there are several first heating plates 10. The several first heating plates 10 are connected in sequence and arranged longitudinally. The number of the first heat insulation plates 11 is the same as that of the first heating plates 10. The several first heat insulation plates 11 are connected in sequence and arranged longitudinally.

[0043] As an implementation manner, as shown in Figure 6 and Figure 9 , there are four first heating plates 10 and two first heat insulation tubes. They are arranged one above the other, and one first heat insulation tube corresponds to two first heating plates 10.

[0044] As an implementation manner, there are six first heating plates 10 and three first heat insulation tubes. They are arranged in the upper, middle and lower positions, and one first heat insulation tube corresponds to two first heating plates 10.

[0045] As an implementation manner, there are two first heating plates 10 and one first heat insulation tube. One first heat insulation tube corresponds to two first heating plates 10.

[0046] That is to say, the present utility model does not specifically limit the number of the first heating plate 10, the first heat insulation plate 11 and the first heating tube 12. Those skilled in the art can selectively set them according to factors such as the structure and size of the PTFE product. For example, for a relatively long medical catheter, a larger number of the first heating plate 10, the first heat insulation plate 11 and the first heating tube 12 can be set.

[0047] Further, there are several second heating plates 13, and the several second heating plates 13 are connected in sequence and arranged longitudinally. The number of the second heat insulation plates 14 is the same as that of the second heating plates 13, and the several second heat insulation plates 14 are connected in sequence and arranged longitudinally.

[0048] The settings of the second heating plate 13, the second heat insulation plate 14 and the second heating tube 15 are the same as those of the first heating plate 10, the first heat insulation plate 11 and the first heating tube 12, and will not be elaborated here.

[0049] Further, the second heat curing assembly 4 is connected with several fixing members 17, and there are two brackets 8 and two telescopic cylinders 9 respectively.

[0050] The fixing member 17 is used to connect the second heat curing assembly 4 with other devices or structures, fix the second heat curing assembly 4, and increase the stability of the second heat curing assembly 4.

[0051] Further, the frame 2 includes several cross beams 18 and several support columns 19. The several cross beams 18 surround to form a rectangle. One end of the several support columns 19 is connected to the cross beam 18, and the other end of the several support columns 19 is connected with casters 20.

[0052] As an implementation manner, as Figure 10 shown, there are four cross beams 18 in total, two long and two short. The four cross beams 18 are connected end to end to form a rectangular frame 2. There are also four support columns 19. One end of the four support columns 19 is connected to the four corners of the rectangular frame 2. Adjustable casters 20 are provided at the other end of the four support columns 19, which is convenient for moving the overall tooling.

[0053] As an implementation manner, as Figure 3 and Figure 4 shown, several third heat insulation plates form a heat insulation cover 1. The heat insulation cover 1 is slightly larger than the first heat curing assembly 3, and the first heat curing assembly 3 can be arranged in the heat insulation cover 1. When the heat insulation cover 1 is in a closed state, the second heat insulation plate 14 of the second heat curing assembly 4 serves as the bottom cover of the heat insulation cover 1 and forms a closed space with the heat insulation cover 1.

[0054] As an implementation manner, as Figure 5As shown, a shield 21 is further provided between the heat insulation cover 1 and the first heat curing assembly 3. The first heat curing assembly 3 is arranged inside the shield 21. When the heat insulation cover 1 is in the closed state, the shield 21 shines on the second heat curing assembly 4, playing a protective role for the heat curing assembly.

[0055] For the medical guide wire heat curing tooling of the present utility model, a heat insulation cover 1 is formed by several third heat insulation plates 16. When the telescopic cylinder 9 retracts backward, the heat insulation cover 1 moves backward along the guide rail 7 by connecting the roller 6 through the connecting piece 5, so that the heat insulation cover 1 is in the open state. When the coated medical catheter enters the curing device, that is, between the first heat curing assembly 3 and the second heat curing assembly 4, the telescopic cylinder 9 extends forward at this time. The heat insulation cover 1 moves forward along the guide rail 7 by connecting the roller 6 through the connecting piece 5 to cover the coated medical catheter. The first heating tube 12 and the second heating tube 15 work to heat the medical catheter through the first heating plate 10 and the second heating plate 13, and the coated medical catheter is heat cured at a temperature of 400°C. When the coated medical catheter reaches the heat curing time, the telescopic cylinder 9 retracts backward again. The heat insulation cover 1 moves backward along the guide rail 7 by connecting the roller 6 through the connecting piece 5 to take out the heat cured medical catheter. The heat insulation cover 1 closes again to ensure the temperature inside the heat curing device, and the PTFE product is heat cured.

[0056] By curing the medical guide wire with the heat curing tooling of the present utility model, the heat curing tooling has a fast temperature rise, can produce continuously, does not have the problem of waiting for the cyclic temperature rise and fall of the air blast drying oven, has high production efficiency, and the heat curing tooling is set for the medical guide wire, and the length of the heat curing assembly is relatively long, meeting the requirements of the PTFE product for long length and high temperature curing.
