Description

Technical Field

[0001] This utility model relates to a device for pressing steel wire and cylindrical lead seal together, belonging to the field of lead seal technology. Background Technology

[0002] A lead seal is a sealing device that uses a physical locking mechanism to prevent tampering. Its core function is to verify whether goods have been opened without authorization during transportation or use. Depending on the person applying the seal, they can be divided into three categories: customs seals, commodity inspection seals, and commercial seals. Each lead seal has a unique serial number, and its ability to be opened only by force gives it legal validity. It is widely used in customs supervision, electrical instruments, logistics, and other fields.

[0003] A Chinese patent discloses a device for pressing steel wire and cylindrical lead seals, including a cylinder. An upper support base is located below the cylinder, and a lower support base is connected to the upper support base via a support column. The cylinder includes a cylinder barrel and a cylinder rod. A positioning plate is sleeved on the cylinder rod and below the upper support base. An upper mold is connected to the lower cylindrical sleeve and at the end of the cylinder rod. A platform is provided on the lower support base, and a lower mold is connected to the platform via a lower mold support base. The upper and lower molds correspond to each other. A stop strip is also provided on the platform and outside the lower mold support base. The advantages of this invention are: the upper mold has a raised surface and a circular positioning column, and the lower mold has a groove with a raised surface at the bottom, enabling precise positioning; it also provides high efficiency and good consistency in pressing lead seals. When pressing the cylindrical lead seal with the steel wire, the lead seal will deform due to the characteristics of the lead seal material. At this time, the deformed lead seal may get stuck in the lower mold. The above device is not equipped with a structure to automatically remove the lead seal from the lower mold. Therefore, in actual use, the operator needs to remove the lead seal by himself. This process is cumbersome and inconvenient, and not convenient for the operator to use.

[0004] To address this, a device for pressing steel wire and cylindrical lead seal is proposed. Utility Model Content

Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0019] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0020] Example 1, such as Figure 1-5 As shown, this utility model embodiment provides a steel wire and cylindrical lead seal pressing device, including a workbench 1, a mounting frame 3 fixedly installed at the bottom of the workbench 1, a support frame 4 fixedly installed at the top of the workbench 1, a hydraulic cylinder 5 fixedly installed at the top of the support frame 4, an upper mold 6 fixedly installed at the bottom of the hydraulic cylinder 5, and a lower mold 7 fixedly installed at the top of the workbench 1. A discharge assembly 2 is provided on the surface of the mounting frame 3, the discharge assembly 2 including a motor 201, the motor 201 fixedly installed on the rear side of the mounting frame 3, and a shaft 202 fixedly connected to the output end of the motor 201. Turntables 205 are movably connected to the front side of the surface of the mounting frame 3, and mounting rods 206 are fixedly installed on the front side of each of the two turntables 205. Movable shells 207 are provided on the left and right sides of the front side of the mounting frame 3, and the front sides of the two mounting rods 206 are slidably connected to the two movable shells 207. Inside the cavity of housing 207, vertical rods 214 are fixedly installed on the top of the two movable housings 207. Connecting rods 208 are movably connected to the top of the two vertical rods 214. Ejector rods 209 are movably connected to the other ends of the two connecting rods 208. Ejector rods 209 pass through the inner surfaces of the worktable 1 and the lower mold 7 and extend into the inner cavity of the lower mold 7. Transmission bevel gears 203 are fixedly installed on the left and right sides of the surface of the shaft 202. Driven bevel gears 204 are fixedly connected to the rear side of the two turntables 205. The surfaces of the two transmission bevel gears 203 mesh with the surfaces of the two driven bevel gears 204. The dimensions of the two turntables 205 are the same, and the rotation directions of the two turntables 205 are opposite. A control switch 210 is fixedly installed on the surface of the mounting bracket 3. The output terminal of the control switch 210 is electrically connected to the input terminal of the motor 201.

[0021] By setting the discharge component 2, the turntable 205 rotates in the opposite direction through the output of the motor 201, so that the moving shell 207 and the connecting rod 208 cooperate with each other, driving the ejector rod 209 to push the pressed lead seal out of the inner cavity of the lower mold 7, realizing automatic material discharge, improving the flexibility and convenience of equipment use, saving the operator the step of taking the lead seal out of the lower mold 7, ensuring the continuity of the pressing of the lead seal and the steel wire, and making it convenient for the operator to use.

[0022] Example 2, as follows Figure 1-4 As shown, in one embodiment, the mounting frame 3 has movable slots 211 on both the left and right sides of its surface, and two vertical rods 214 pass through the inner cavities of the two movable slots 211. Guide rods 212 are fixedly installed on both the upper and lower sides of the mounting frame 3. Two movable shells 207 are slidably connected to the surfaces of the two guide rods 212. A support block 213 is movably connected to the surface of the shaft 202 through a bearing. The front side of the support block 213 is fixedly installed on the rear side of the mounting frame 3.

[0023] By setting the movable groove 211, the movement of the vertical rod 214 can be limited to prevent it from deviating during movement, which would affect the material discharge of the lead seal. By setting the guide rod 212, the movement of the movable shell 207 can be limited to ensure the accuracy of the linear movement of the movable shell 207. By setting the support block 213, the shaft 202 can be supported to prevent the shaft 202 from falling off after long-term use.

[0024] In operation, this invention works as follows: First, the material is placed in the inner cavity of the lower mold 7. Then, through the extension of the hydraulic cylinder 5, the upper mold 6 presses the lead seal downwards. When the upper mold 6 presses down, the lead seal material, due to the influence of the lower mold 7, cannot expand outwards but is forced to flow towards the central steel wire and the pre-reserved space between the upper and lower molds 6 and 7, thus achieving the pressing of the cylindrical lead seal and the steel wire. Subsequently, after the hydraulic cylinder 5 moves the upper mold 6 out of the inner cavity of the lower mold 7, the shaft... Rod 202 drives transmission bevel gear 203 to rotate. Transmission bevel gear 203 and driven bevel gear 204 cooperate with each other. The two turntables 205 rotate in opposite directions. At this time, mounting rod 206 moves in a circle. Mounting rod 206 drives moving housing 207 and vertical rod 214 to move inward. Vertical rod 214 cooperates with connecting rod 208 to make ejector rod 209 move upward. The top of ejector rod 209 ejects the pressed lead seal in the inner cavity of lower mold 7, realizing automatic material discharge.

[0025] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
