Description

Technical Field

[0001] This utility model relates to the field of graphite production technology, and in particular to a rapid tensioning device for isostatic graphite sleeves. Background Technology

[0002] In the isostatic pressing process of graphite preform forming, a rubber sleeve (usually made of rubber or elastic material) needs to be stretched into the corresponding mold to encapsulate the graphite powder and achieve molding under high pressure. However, existing rubber sleeve stretching technology has many problems:

[0003] From a current technological perspective, the application of rubber sleeves requires multiple people working together, which is not only inefficient but also extremely labor-intensive. Furthermore, poor finishing of the rubber sleeves directly affects the surface smoothness of the graphite preform, thereby reducing the effective utilization rate of graphitized products.

[0004] Specifically, the problems mainly include three aspects: First, the rubber sleeve is heavy, and the labor intensity is high when it is handled and operated manually, requiring a lot of manpower; second, the stretching and finishing process is time-consuming, and the stretching operation of the rubber sleeve is laborious, which seriously restricts the production efficiency; third, manual operation is prone to poor finishing, and the wrinkles produced by the rubber sleeve will cause the green blank to sink, which directly affects the appearance flatness of the graphite green blank and has an adverse effect on the quality of subsequent products. Utility Model Content

[0005] The purpose of this invention is to provide a rapid tensioning device for isostatic graphite rubber sleeves, which solves the above-mentioned problems.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a rapid tensioning device for isostatic graphite sleeves, including a roller conveyor, a housing, a frame one, and a frame two. The front of the roller conveyor is equipped with a housing, and the top of the housing is equipped with frames one and two on both sides. Telescopic rods are installed at the front ends of the top of frames one and two, and support blocks are provided at the front ends of the bottom of frames one and two. The output shaft at the bottom of the telescopic rod is connected to the top of the support block. Clamping components are provided around the support block at the front end of the bottom of frame one, and roller pressing components are provided around the support block at the front end of the bottom of frame two.

[0007] Preferably, a mold is placed on top of the roller conveyor, and a rubber sleeve is installed inside the mold.

[0008] Preferably, the gripping assembly includes gripper rods fixed around a bottom front support block of the frame, with gripper blocks at the ends of the gripper rods and gripper assemblies at the bottom of the gripper blocks.

[0009] Preferably, a push rod is provided inside the gripper support rod, and the output end of the push rod is fixedly connected to the gripper support block.

[0010] Preferably, the roller pressing assembly includes roller support rods fixed around the bottom front support block of the second frame, roller support rods having roller frames at their ends, and smoothing rollers being mounted on the roller frames.

[0011] Preferably, a push rod is provided inside the roller support rod, and the output end of the push rod is fixedly connected to the roller frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model provides a rapid splicing device for isostatic graphite sleeves. By employing a robotic arm collaborative work platform, the sleeve is gripped by an adaptive gripper. Only two people are needed to assist in lifting the top of the sleeve to complete the loading process, significantly reducing manual intervention. At the same time, automated components such as the robotic arm, telescopic rod, and push rod replace manual handling and stretching operations, effectively reducing labor intensity and solving the problem of high labor consumption.

[0014] 2. This utility model provides a rapid stretching device for isostatic graphite sleeves. It achieves rapid and precise positioning using an infrared positioning mold. A robotic arm drives adaptive grippers to automatically complete the gripping, transportation, placement, and stretching operations of the sleeves, replacing the slow manual positioning and stretching process. Furthermore, a roller conveyor system automatically transports the mold, and the rotating rollers of the roller pressing assembly quickly smooth the sleeves. The entire process is seamless and efficient, significantly shortening the stretching and finishing time and improving production efficiency.

[0015] 3. This utility model provides a rapid stretching device for isostatic graphite sleeves. By expanding the sleeve opening through the outward movement of adaptive grippers, the sleeve is stretched onto the upper edge of the mold and secured with flexible clamps, avoiding the instability of manual finishing. Simultaneously, a vacuum pump pre-adsorbs the sleeve, and the smoothing rollers of the rolling assembly expand and roll to eliminate local wrinkles. Furthermore, a laser flatness meter monitors and guides the smoothing operation in real time, ensuring a tight fit between the sleeve and the inner wall of the mold, resulting in a smooth surface. This effectively solves the problem of green blank depressions caused by sleeve wrinkles, guaranteeing the smoothness of the graphite green blank's appearance. Attached Figure Description

[0025] Combination Figures 1 to 6 As shown, this utility model discloses a rapid tensioning device for isostatic graphite sleeves, comprising a roller conveyor 1, a housing 2, a first frame 3, and a second frame 4.

The output shaft at the bottom of the telescopic rod 5 is connected to the top of the support block 6. Clamping components are provided around the support block 6 at the front ends of the bottom of the first frame 3, and roller pressing components are provided around the support block 6 at the front ends of the bottom of the second frame 4.

[0026] A mold 11 is placed on top of the roller conveyor 1, and a rubber sleeve 12 is installed inside the mold 11.

[0027] The gripping assembly includes gripper support rods 7 fixed around the bottom front support block 6 of the frame 3. The end of the gripper support rod 7 is provided with a gripper support block 71, and the bottom of the gripper support block 71 is provided with a gripper assembly 72.

[0028] The gripper support rod 7 has a push rod 9 inside, and the output end of the push rod 9 is fixedly connected to the gripper support block 71.

[0029] The roller pressing assembly includes roller support rods 8 fixed around the bottom front support block 6 of the frame 2 4, roller support rods 81 are provided at the ends of roller support rods 81, and smoothing rollers 82 are provided on roller support rods 81.

[0030] The roller support rod 8 has a push rod 9 inside, and the output end of the push rod 9 is fixedly connected to the roller frame 81.

[0031] Specifically,

[0032] Frame 1 (3) and Frame 2 (4) can be equipped with robotic arms or other devices to move the gripping and rolling components, providing a basis for position adjustment for each stage of operation.

[0033] Working principle:

[0034] In the automatic feeding stage of the rubber sleeve 12, two people pull up the top of the rubber sleeve 12 to facilitate the adaptive gripper, namely the gripper assembly 72, which is a pneumatic bionic finger sleeve in conjunction with a pressure sensor to automatically identify and grasp the four edges at the opening of the rubber sleeve 12. At the same time, the mold 11 to be pressed is hoisted to the work station of the work platform by a person. The equipment automatically positions the position and shape of the mold 11 through infrared, providing a positioning basis for the subsequent precise placement of the rubber sleeve 12.

[0035] The mold 11 is conveyed by the roller conveyor 1 and moved to the corresponding position of the clamping assembly. The support block 6 is pushed down by the telescopic rod 5, which moves the clamping assembly downward and places the rubber sleeve 12 into the mold 11. To ensure that the end of the rubber sleeve 12 can be automatically stretched at the top of the mold 11, the push rod 9 inside the gripper support rod 7 pushes the gripper support block 71 outward, which moves the gripper assembly 72 outward, thereby expanding the opening size of the rubber sleeve 12 so that the rubber sleeve 12 is stretched at the top of the mold 11. Then, the robotic arm clamps the end of the rubber sleeve 12, and in conjunction with the above-mentioned expansion action, it further ensures that the rubber sleeve 12 is stably stretched at the top of the mold 11. Finally, a flexible clamp is used to clamp the upper part of the rubber sleeve 12 to complete the fixation of the rubber sleeve 12.

[0036] After fixing, the roller conveyor 1 continues to convey the mold 11, moving it to the position of the roller pressing assembly. The vacuum pump is started, and by controlling the opening of the vacuum valve, the rubber sleeve 12 is pre-adsorbed onto the mold 11, enhancing the initial fit between the rubber sleeve 12 and the mold 11. Then, the telescopic rod 5 pushes down the support block 6, moving the roller pressing assembly into the mold 11; the push rod 9 pushes the roller shaft frame 81 outward, causing the smoothing roller shaft 82 (i.e., the rotating roller) to expand outward. The smoothing roller shaft 82 pushes the rubber sleeve 12, making it fit tightly against the inner wall of the mold 11, and the rolling action smooths the rubber sleeve 12, eliminating local wrinkles. During the smoothing operation, the laser flatness meter monitors the surface of the rubber sleeve 12 in real time, and the data is transmitted to the roller control system to accurately guide the smoothing operation.

[0037] After the smoothing operation is completed, the roller pressing assembly is reset using the telescopic rod 5, thus completing the entire stretching process of the rubber sleeve 12.
