[0033] Example 1, please refer to Figure 1-7 :

[0034] A full-cover clamping fixture includes a profile frame 1, a profile frame 2, a profile frame 3, and a profile frame 4; the profile frame 1, the profile frame 2, the profile frame 3, and the profile frame 4 are connected together by multiple angle codes 5, and a double-rod cylinder 7 is installed on both sides of the top of the profile frame 1. The cylinder push block of the double-rod cylinder 7 is installed with a die movable block 8 using an M4 flat head hexagon screw. The die movable block 8 has a detachable structure design, which can also facilitate the subsequent replacement of dies of different models; the top of the profile frame 2 and the profile frame 4 and away from the double-rod cylinder 7 are connected together by multiple angle codes 5. A punch fixing block 6 is installed at the position of the cylinder 7. The punch fixing block 6 has a detachable structural design, which can facilitate the subsequent installation of different types of punches. The punch fixing block 6 is away from the die movable block 8 and the position corresponds. It also includes a blank 9. The blank 9 is clamped between the two punch fixing blocks 6, and the sealing side of the blank 9 faces the die movable block 8. The shape of one end of the punch fixing block 6 is adapted to the shape of the die movable block 8. The die movable block 8 is in an open state. The die movable block 8 can cover one end of the punch fixing block 6 by being pushed by the double-rod cylinder 7.

[0035] See also Figure 1 and Figure 6 Furthermore, a fixing part is provided in the angle code 5, and the fixing part includes an M6 screw 501 and a T-nut 502. One end of the profile frame 2 2 and the profile frame 4 4 ​​is fixed to the profile frame 1 through two angle codes 5 and the fixing part; two angle codes 5 are respectively provided at both ends of the profile frame 3, and the two ends of the profile frame 3 3 are respectively fixed to the profile frame 2 2 and the profile frame 4 4 ​​through the angle codes 5 and the fixing part.

[0036] Specifically, the angle code 5 is fixed to the corresponding component through a fixing piece, an M6 screw 501 is placed on the inner side of the angle code 5, and a T-nut 502 is inserted into the corresponding profile frame. After the M6 ​​screw 501 and the T-nut 502 are tightened, the connection and fixation of the corresponding profile frame can be achieved. The angle code 5 with a 90-degree angle is used for connection, so that the installation of the fixture is not affected by the structural installation of any equipment, and the fixture can be put on the machine for mold adjustment in a short time.

[0037] See also Figure 1-3Furthermore, a plurality of through holes are provided on the top of the punch fixing block 6, in which M6 screws 2 601 are inserted, and T-nuts 2 are threadedly connected to the bottom of the M6 ​​screws 2 601. The two punch fixing blocks 6 are respectively fixed on the profile frame 2 2 and the profile frame 4 4 ​​by M6 screws 2 601 and T-nuts 2.

[0038] Specifically, the two punch fixing blocks 6 are fixed to the profile frame 2 2 and the profile frame 4 4 ​​by M6 screw 2 601 and T-nut 2. The M6 ​​screw 2 601 passes through the punch fixing block 6 and is threadedly connected with the T-nut 2, and the T-nut 2 is placed inside the profile frame 2 2 and the profile frame 4 4. By tightening the M6 ​​screw 2 601 and the T-nut 2, the punch fixing block 6 can be fastened, and the position of the punch fixing block 6 can be adjusted later when necessary, which has strong adaptability.

[0039] See also Figure 2 、 Figure 3 、 Figure 5 and Figure 7 Furthermore, two through holes are opened on the top of the double-rod cylinder 7, and M4 screws 701 are inserted into the through holes. The bottom of the M4 screws 701 is threadedly connected with T-nuts 3 702. The double-rod cylinder 7 is fixed to the profile frame 1 through the M4 screws 701 and T-nuts 3 702.

[0040] Specifically, the M4 screw 701 passes through the double-rod cylinder 7 and is threadedly connected to the T-nut three 702. The T-nut three 702 is placed inside the profile frame 1. Through the threaded connection between the T-nut three 702 and the M4 screw 701, the double-rod cylinder 7 can be fixed on the profile frame 1.

[0041] See also Figure 5 Furthermore, a plurality of T-shaped slots are provided in the inner wall of the movable block 8 of the die, and a T-shaped rubber strip 801 is inserted into each T-shaped slot.

[0042] Specifically, the T-shaped rubber strip 801 has good tensioning force. It is installed in the T-shaped slot and automatically tightens the connection with the die movable block 8. The T-shaped rubber strip 801 can be positioned without screws. The purpose of installing the T-shaped rubber strip 801 is to make the fixture clamp the product more effectively, fit the product, and prevent the product from being damaged during the production process.

[0043] Example 2, please refer to Figure 8-10 :

[0044] A heat sink 10 is also installed at the top of each double-rod cylinder 7 and near the side of the die movable block 8. Cooling liquid flows through the inside of the heat sink 10. One side of the heat sink 10 is connected to a liquid inlet 1001, and the other side is connected to a liquid outlet 1002. The heat sink 10 is made of aluminum, and the side wall thickness of the heat sink 10 close to the double-rod cylinder 7 is thinner than the side wall thickness away from the double-rod cylinder 7.

[0045] Specifically, the heat sink 10 made of aluminum has good thermal conductivity, and there is circulating coolant inside the heat sink 10, which can better take away the heat of the double-rod cylinder 7 and optimize the working environment of the double-rod cylinder 7. The liquid inlet 1001 is used to feed the coolant through the pump body, and the liquid outlet 1002 is used to connect the pipe for discharging the coolant. The discharged coolant has a certain amount of heat. After the coolant is cooled by the liquid storage tank or the heat exchanger, it is transported to the liquid inlet 1001 again through the pump body, thereby forming a good circulating cooling system. At the same time, the side wall thickness of the heat sink 10 close to the double-rod cylinder 7 is thinner than the side wall thickness away from the double-rod cylinder 7. The purpose is to make the thinner side of the side wall of the heat sink 10 close to the double-rod cylinder 7 for better heat absorption and heat conduction.

[0046] During installation:

[0047] First, use angle bracket 5, M6 screw 501 and T-nut 502 to install profile frame 1, profile frame 2, profile frame 3 and profile frame 4 to form a combined profile frame. Then use M6 screw 601 and T-nut 2 to fix the two punch fixing blocks 6 to profile frame 2 and profile frame 4, respectively. Finally, use M4 screw 701 and T-nut 3 702 to fix the two double-rod cylinders 7 to both sides of the top of profile frame 1.

[0048] After installation, the blank 9 can be held between the two punch fixed blocks 6, and the two double-rod cylinders 7 (model TN25-90) are started. The double-rod cylinders 7 drive the die movable block 8 to push forward, pressing the blank 9 to form an absolute V-mouth clamping state. After processing is completed, release the double-rod cylinders 7, exit the clamping state, and take out the product, thus completing the entire process of processing the entire product.
