Abstract
Description
Technical Field
[0001] This invention relates to the field of amorphous alloy die casting technology, and particularly to an anvil manufactured using an amorphous alloy die casting process. Background Technology
[0002] Surgical staplers are mainly used in minimally invasive surgical procedures. In recent years, with the increasing penetration rate of minimally invasive technology, the surgical stapler industry has also developed rapidly. Compared with foreign countries, the penetration rate of minimally invasive technology in China is relatively low, indicating huge potential for future growth, and the market size of staplers will also increase accordingly. Currently, the manufacturing process of medical anvils is as follows: CNC machining to form the mounting groove and body shape; stamping the stapler recess; forming the stapler cover and shaping its side wings; welding the stapler body and cover; CNC machining the cutting groove; heat treatment; grinding and cleaning; and plating. This process is costly, time-consuming, and inefficient. Furthermore, 1. due to its complex structure, it usually requires extensive CNC machining; 2. because the stapler recess structure is too small, it can only be achieved through stamping; 3. key indicators such as the position and contour of the recess become unstable with the increasing use of the stamping die. Therefore, there is an urgent need in the market for a low-cost processing technology that can meet product performance requirements, improve production efficiency, and provide stability. Summary of the Invention

The melt is then injected into the mold at a high speed and high pressure of 0.7m / s-1.4m / s. The mold temperature is selected as 175℃-210℃, the pressure boosting position is selected as 304mm-311mm, and the high speed position is selected as 289mm-302mm to obtain the anvil die casting blank.

[0012] Step (3) Laser engraving blanking refers to placing the die-cast anvil blank, which is connected to the flow channel and the material handle, into the positioning fixture for laser engraving. The positioning fixture is placed on the worktable of the laser engraving machine. The laser engraving program of the anvil is opened, the processing pedal is started, and the set program is automatically started.

After the time is up, the product is taken out of the furnace and a film will be formed on the product surface, which can greatly improve the roughness of the product's nail pit. The coating is then complete.

[0024] Example 1: A method for manufacturing an anvil includes the following steps: (1) mixing and melting materials to form small blocks; (2) die casting; (3) laser engraving blanking; (4) deburring; (5) CNC machining; (6) polishing; (7) grinding; (8) PVD coating.
[0025] The specific steps are as follows:
[0026] (1) Mix and melt the materials and then make small pieces. Weigh the following materials according to the mass ratio: 63 parts zirconium powder, 25.5 parts copper powder, 6 parts nickel powder, 1.5 parts titanium powder, 3.5 parts aluminum powder, and 0.5 parts yttrium powder. Place them in a melting furnace and heat the temperature to 1000-1200℃. To prevent the raw materials in the melting furnace from oxidizing, evacuate the furnace and use argon gas to protect them from oxygen. After melting into a liquid state, inject the mixture into the mold cavity for making the feed. The mold is equipped with cooling circulating water. The liquid feed enters the mold cavity and is quickly cooled into solid blocks. Then, the mixture is taken out and processed into small pieces of raw material less than 20mm by a crusher.
[0027] (2) Die casting. The raw material, which is broken into small pieces of less than 20 mm, is placed into the storage bin of the die casting equipment, which uses a Japanese Toyo 250T die casting machine. The vacuum is evacuated to below 50 Pa. Under this vacuum or argon protection, the raw material is heated to 950°C by high frequency heating. After the raw material is completely melted, it is automatically poured into the injection chamber. The melt is injected into the mold at a high speed and high pressure of 0.9 m / s. The mold temperature is selected as 200°C, the pressure boosting position is selected as 308 mm, the high speed position is selected as 290 mm, the barrel insulation temperature is selected as 120°C, and the clamping force is selected as 2300 KN. After the mold is ejected, the die casting blank with the anvil connected to the material shank and the runner is obtained.
[0028] (3) Laser engraving blanking. Place the die-cast blank of the anvil seat, which is connected to the flow channel and the material handle, into the positioning fixture for laser engraving. The positioning fixture is placed on the worktable of the laser engraving machine. Open the laser engraving program of the anvil seat, start the processing pedal, and the set program will start automatically. The laser engraving machine will emit a laser to cut the flow channel on the anvil seat. Leave a 0.1mm margin between the cutting position and the anvil seat for the next processing step. After cutting, the blank of the medical anvil seat is obtained.
[0029] (4) Remove burrs. Use a burr remover to manually remove the burrs at the anvil inlay line and the two side mold lines after laser engraving.
[0030] (5) CNC machining. Place the anvil blank on the machining platform of the Brother CNC machine tool, start the machining program of the machine tool, remove the machining allowance reserved for the anvil blank, and perform high-precision machining on important control dimensions.
[0031] (6) Polishing. Hold the CNC-machined anvil close to the polishing wheel, preferably with a speed of 800-1000 r / min, and choose a nylon wheel as the polishing wheel material. Process the blank until the anvil blank is obtained.
[0032] (7) Grinding. Place the polished anvil, grinding stone, and grinding fluid into a high-power high-speed centrifugal grinder for grinding and cleaning to remove the rolled edges from CNC machining and the dirt from polishing. Start the high-power high-speed centrifugal grinder, select green silicon carbide 3×3 as the grinding stone material, select a speed of 120 r / min, and a time of 30 min. After processing is completed, take it out for cleaning and pick out the grinding stone in the gap of the anvil.
[0033] (8) PVD coating. After cleaning the ground anvil blank, place it on the electroplating fixture, heat it in the furnace and perform surface treatment; after the time is up, take it out of the furnace and a coating will be formed on the product surface, which can greatly improve the roughness of the product's nail pits. The coating is then complete.
[0034] Due to the continuous improvement of medical technology in my country, existing industry standards are no longer sufficient to meet the testing requirements of existing anvils. Therefore, we have added a new testing fixture for clamping six layers of foam to the anvil to test its strength. This fixture accurately simulates the working conditions of the anvil and can further test its strength, precisely measuring the performance impact of different raw material ratios on anvils.
[0035] like Figure 3 As shown, the test fixture for clamping six layers of foam with an anvil is set up to simulate actual working conditions. It includes a fixed block 8, a movable rod 9, and a fixed rod 10. The medical anvil and staple cartridge are fixed together between the movable rod 9 and the fixed rod 10 using a fixing pin 11. The fixed rod 10 is fixed to the fixed block 8 using a fixing pin 7. The baffle 3 and the fixed block 8 are fixed to the abutment 1 with screws. A cylinder 2 is set behind the baffle and fixed to the baffle with screws 4. A connector 5 is set between the movable rod 9 and the cylinder 2. Under the pushing action of the cylinder 2, the movable rod 9 also moves forward, causing the anvil to clamp downwards. As shown in the figure, an electromagnetic control valve is installed behind the cylinder. The electromagnetic control valve controls the air intake of the two air intake pipes A and B to control the forward and backward movement of the cylinder 2. When the switch is pressed, air intake is introduced through air pipe B, and the cylinder moves forward, with the anvil clamping the foam. When the switch is released, air intake is introduced through air pipe A, and the cylinder moves backward, with the anvil releasing the foam. One reciprocating motion is recorded as one cycle. The number of times the anvil clamps the foam is used to determine whether the strength meets the standard requirements.
[0036] Clamping force test: Clamping six layers of foam and performing 12 repeated clamping tests, with no breakage or cracks. A clamping test with more than 12 clamping cycles without breakage or cracks is considered excellent; a clamping test with more than 6 clamping cycles without breakage or cracks is considered acceptable.

Only one element was changed in each example, and the optimal range was tested in increments of one unit. The suitable range for each element was determined by testing the clamping force of the anvil 12 times, clamping six layers of foam.
