Description

Technical Field

[0001] The utility model relates to the field of surgical knife production and processing equipment, and more particularly to a surgical knife quenching device. Background Art

[0002] During the scalpel production process, a blade blank is first stamped out of a steel coil using a die. This blank is then heated in a high-temperature furnace. The blade blank is then cooled down after leaving the furnace, commonly known as quenching, to improve the blade's toughness and ensure it meets surgical requirements. Existing quenching methods include water quenching and oil quenching. However, both methods involve direct contact between the blade blank and water or oil, which can create impurities on the inverted blade surface, increasing subsequent polishing time and reducing production efficiency.

[0016] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0017] Reference Figure 1 one Figure 4 As shown, a surgical knife quenching device of this embodiment includes a quenching box 1 and a accommodating cavity 2 arranged on the quenching box 1, quenching holes 3 are provided on the opposite sides of the quenching box 1, and a quenching channel 4 is provided between the two quenching holes 3. The quenching channel 4 is located in the accommodating cavity 2, and the quenching channel 4 is for the blade blank to pass through. The quenching box 1 is provided with an inlet pipe 51 and an output pipe 52 near the two ends, and the inlet pipe 51 and the output pipe 52 are connected to the accommodating cavity 2, and the other ends of the inlet pipe 51 and the output pipe 52 are connected to the external circulation equipment.

[0018] With the above technical solution, when the equipment is in operation, the blade blank heated in the high-temperature furnace enters the quenching channel 4 and then exits. Through isolated quenching, impurities are prevented from adhering to the surface of the blade blank during the quenching process, shortening the subsequent polishing and grinding time, improving production efficiency, and reducing medium waste and environmental pollution.

[0019] During quenching, the external circulation equipment is operated, so that the medium enters the containing chamber 2 from the inlet pipe 51, and then is output from the output pipe 52, dissipates heat externally, and then is re-input into the containing chamber 2. The medium is recycled with low loss, reducing the quenching cost.

[0020] As an improved specific implementation, there is a gap 6 between the side of the quenching channel 4 and the quenching box 1.

[0021] Through the above technical solution, a gap 6 is provided between the side of the quenching channel 4 and the quenching box 1 for the medium to flow through, which can better remove heat and improve the quenching effect.

[0022] As an improved specific embodiment, a main heat conducting plate 71 is provided on the outside of the quenching channel 4, and the main heat conducting plate 71 extends along the extension direction of the quenching channel 4. Transmission notches 711 are provided at both ends of the main heat conducting plate 71, and the positions of the transmission notches 711 correspond to the positions of the inlet pipe 51 and the outlet pipe 52.

[0023] Through this technical solution, the main heat exchange plate 71 is connected to the quenching channel 4, expanding the heat exchange area and maintaining the quenching channel 4 at the desired temperature, ensuring the quenching effect. The transmission notches 711 at both ends of the main heat exchange plate 71 correspond to the positions of the inlet pipe 51 and the outlet pipe 52. This allows the medium entering the receiving chamber 2 through the inlet pipe 51 to smoothly and quickly fill the receiving chamber 2, and the medium in the receiving chamber 2 can also smoothly exit through the outlet pipe 52.

[0024] As an improved specific implementation, a secondary heat conducting plate 72 is provided on the main heat conducting plate 71 , and the secondary heat conducting plate 72 extends along the extension direction of the main heat conducting plate 71 .

[0025] Through the above technical solution, the auxiliary heat conducting plate 72 further expands the heat conducting area, improves the heat exchange effect, and further improves the quenching effect.

[0026] As an improved specific implementation, the main heat-generating plate 71 is connected to the quenching box 1 .

[0027] Through the above technical solution, the main heat plate 71 is connected to the quenching box 1, which improves the structural stability of the main heat plate 71, improves the stability of the quenching process, and prolongs the service life.

[0028] As an improved specific implementation, a flexible scraper 8 is provided on the quenching channel 4, and the scraper 8 is used to clean the surface of the blade blank.

[0029] Through the above technical solution, the scraper 8 is set at one end where the blade blank enters. After the surface of the blade blank is cleaned, the blade blank enters the quenching channel 4 to avoid scratching the surface of the blade blank during the quenching process, thereby reducing the defective rate. In addition, the upper and lower end surfaces of the blade blank have a high degree of fit with the quenching channel 4, and the quenching effect is good.

[0030] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention.
