Description

Technical Field

[0001] This utility model relates to the field of nail production, and more specifically, to a pneumatic nail forming mold. Background Technology

[0002] In the production process of pneumatic nail strips, the forming quality and production efficiency of the nail strips directly affect their subsequent performance.

[0003] Traditional pneumatic paddle pin forming molds generate significant heat during the forming process due to friction and material deformation. If this heat is not cooled promptly, it can lead to a decline in the material properties of the paddle pins, resulting in surface cracks or uneven hardness. Furthermore, the pin head cutting process is limited, making it difficult to flexibly adjust the cutting angle as needed. This hinders the diverse shape requirements of paddle pins for different applications; for example, right-angled pins are suitable for general fixing, while beveled pins are better suited for driving into hard materials. Traditional angle adjustment mechanisms are also cumbersome, requiring the disassembly of some components for angle adjustment, which is time-consuming and labor-intensive. Moreover, the adjusted limits are unstable, and vibration during cutting can cause angle deviations, affecting cutting accuracy. Therefore, inventing a pneumatic paddle pin forming mold to address these problems has become a pressing issue for those skilled in the art. Utility Model Content

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Please see Figure 1 and Figure 2 This utility model provides a technical solution: a pneumatic nail forming mold, comprising... A production mold 100 includes a pin bar 110 and a mold cooling assembly 120, with the pin bodies of the pin bar 110 located within the mold cooling assembly 120. A pin head cutting assembly 200 includes a cutting angle adjustment assembly 210 located at the tail of the mold cooling assembly 120. The cutting angle adjustment assembly 210 includes a guide plate 211, which is hinged to the tail of the mold cooling assembly 120. The guide plate 211... The limit transmission is equipped with a cutter 216, which is set to correspond to the nail head of the row of nails 110. The cutting angle adjustment component 210, through the limit hinge design of the guide plate 211, together with the connecting block 212, the hinge rod 213 and the limit rod 214, can quickly adjust the tilt angle of the guide plate 211, thereby changing the cutting angle of the cutter 216 to the nail head of the row of nails 110, meeting the diverse needs of different users for nail head shape, such as 45° bevel angle, 60° bevel angle, etc., and expanding the application range of the product.

[0024] The production mold 100 is a mold in the prior art, used for mounting on equipment for processing nails.

[0025] Please see Figure 3 and Figure 4 The mold cooling assembly 120 includes a lower mold 121 and an upper mold 122. A first hydraulic cylinder 124 is fixedly connected to the back of both the lower mold 121 and the upper mold 122, and the first hydraulic cylinder 124 is located inside the equipment. Both the lower mold 121 and the upper mold 122 are hollow. Water valves 123 are connected to both ends of the back of the lower mold 121 and the upper mold 122, respectively. The water valves 123 are connected to an external water source. Cold water enters the lower mold 121 and the upper mold 122 through the water valves 123 to cool the lower mold 121, the upper mold 122, and the pin array 110, preventing overheating. The cold water circulates within the lower mold 121 and the upper mold 122.

[0026] The lower mold 121 and the upper mold 122 are provided with grooves in the middle that cooperate with the nail body of the pin 110. The lower mold 121 and the upper mold 122 are tightened to make it easier to clamp the pin 110.

[0027] Connecting blocks 212 are fixedly connected to both sides of one end of the guide plate 211. Grooves that mate with the connecting blocks 212 are respectively provided at one end of the lower mold 121 and the upper mold 122. The connecting blocks 212 are hinged to the ends of the lower mold 121 and the upper mold 122, respectively. The guide plate 211 is located at the head of the pins 110. Hinged rods 213 are fixedly connected to the inner side of the connecting blocks 212. The hinged rods 213 are hinged to the lower mold 121 and the upper mold 122. The guide plate 211 is hinged to the connecting blocks 212 in conjunction with the hinged rods 213.

[0028] Please see Figure 4 and Figure 5 A limiting rod 214 is slidably inserted into the other side of the connecting block 212. The limiting rod 214 passes through the side walls of the lower mold 121 and the upper mold 122 and is inserted into the connecting block 212. A handle 215 is fixedly connected to the outer end of the limiting rod 214. The limiting rod 214 is a regular polygon or gear-shaped. The gear-shaped setting can be adjusted to various angles for easy adjustment as needed. Pulling and pushing the handle 215 is used to insert and pull out the limiting rod 214, and the method of adjusting the angle can be modified as needed.

[0029] The cutter 216 has a limit slider at its end, which is slidably connected to the inner wall of the guide plate 211. The guide plate 211 is used to limit the cutter 216, allowing it to tilt and move, thus facilitating the cutting at a suitable angle. Hinges 219 are fixedly connected to both sides of the back of the cutter 216. A hinge joint 217 is hinged to the inner wall of the hinge plate 219. A second hydraulic cylinder 218 is hinged to the other end of the hinge joint 217. The second hydraulic cylinder 218 is fixedly installed at the ends of the lower mold 121 and the upper mold 122. The second hydraulic cylinder 218 pushes the hinge joint 217 to move the cutter 216 and cut the nail heads of the pin row 110.

[0030] Working principle: Mold clamping and cooling stage: The external control system starts the first hydraulic cylinder 124, which pushes the lower mold 121 and the upper mold 122 to move towards each other, clamping the nail body of the pin 110 in the groove in the middle of the lower mold 121 and the upper mold 122 to facilitate the processing of the top cap and nail head; at the same time, coolant (such as circulating cooling water) is introduced into the hollow lower mold 121 and upper mold 122 through the water valve 123. The coolant flows inside the mold, carrying away the heat generated during the molding process of the pin 110 and maintaining the mold temperature stable.

[0031] Cutting angle adjustment stage: When it is necessary to adjust the cutting angle of the nail head of the nail bar 110, the operator holds the handle 215 and pulls the limiting rod 214 outward to disengage the limiting rod 214 from the locked state of the lower mold 121 and the upper mold 122. At this time, the guide plate 211 can rotate around the hinge rod 213. The operator adjusts the tilt angle of the guide plate 211 according to the needs (such as 45°, 60°, etc.). After the angle is determined, the limiting rod 214 is reinserted into the side wall of the lower mold 121 and the upper mold 122. The regular polygon or gear-shaped structure of the limiting rod 214 is used to achieve multi-directional locking to ensure that the angle of the guide plate 211 is fixed.

[0032] Nail head cutting stage: The second hydraulic cylinder 218 is activated. The second hydraulic cylinder 218 pushes the cutter 216 through the hinge joint 217 and the hinge plate 219. The limiting slider at the end of the cutter 216 slides along the inner wall of the guide plate 211 to ensure that the cutter 216 cuts the nail head of the row of nails 110 at a preset angle. After the cutting is completed, the second hydraulic cylinder 218 retracts and drives the cutter 216 to reset, waiting for the next cutting command.

[0033] Cyclic operation: Repeat the above steps of mold clamping and cooling, angle adjustment (as required), and nail head cutting to achieve continuous production of nail 110; by adjusting the angle of guide plate 211, different nail head cutting angles can be flexibly switched to meet diverse production needs.

[0034] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
