Description

Technical Field

[0001] The utility model belongs to the technical field of diamond processing, and particularly relates to a long-distance sampling structure for a six-side top hydraulic press. Background Art

[0002] Superhard materials are suitable for making tools for processing other materials. Especially in the processing of hard materials, they have incomparable advantages and occupy an irreplaceable important position. Superhard materials refer to materials with particularly high hardness, which can be divided into natural and artificial types. The synthesis of artificial superhard materials mainly uses pull-rod or hinge-type six-side top hydraulic presses. Currently, the hinge-type six-side top hydraulic press is more commonly used, and the traditional process of the hinge-type six-side top hydraulic press often adopts a cast six-side top hydraulic press.

[0003] The six-side top hydraulic press utilizes the working principle of the six-side top, and through hydraulic synchronization, six cemented carbide anvils are pushed to extrude the synthetic material to generate high pressure, and high temperature is generated by heating with low-voltage high-power current, so that the internal structure of the synthetic material undergoes qualitative changes to form a new superhard material. When the six-side top hydraulic press is working, the working oil pressure can reach up to 100 MPa at most.

[0004] Therefore, in the synthesis and processing of diamonds, the six-side top hydraulic press is a commonly used device, and the samples of the six-side top hydraulic press are clamped at the center of the six-side top. During sampling, in the existing technology, generally, a person directly reaches in along the gap of the six-side top hydraulic press to take the sample. Since the surface of the sample has a large amount of remaining heat after being processed by the six-side top hydraulic press, and the distance of reaching in at the gap is relatively long, a large inclination angle is required to take the sample. When taking the sample, the whole side of the body reaches in. Due to the large size of the equipment and the high-pressure and high-temperature environment inside, there are safety risks in directly using the manual reaching-in method to take the sample.

[0005] The purpose of the utility model is to provide a long-distance sampling structure for a six-side top hydraulic press. The sampling structure is simple, which is convenient for taking the sample processed by the six-side top hydraulic press at a long distance and improves the operation safety.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A long-distance sampling structure for a six-side top hydraulic press, which includes a holding rod. One end of the holding rod is hinged to a connecting rod, and the end of the connecting rod away from the holding rod is detachably connected with a clamping member.

One end of the clamping claw is rotatably connected with a bracket, and the end of the bracket away from the clamping claw is detachably connected to the side of the connecting rod.

[0007] Further, a rubber sleeve is sleeved on the end of the holding rod away from the connecting rod.

[0020] 101. Six-sided top hydraulic press. Detailed implementation mode

[0021] To further understand the content, features and effects of the present utility model, the following embodiments are cited and detailed below in conjunction with the drawings.

[0022] Please refer to Figures 1 to 3 simultaneously. The long-distance sampling structure of the six-sided top hydraulic press in the embodiment of the present utility model will be described in detail below in conjunction with the drawings.

[0023] As Figure 1 shown, it is assumed that the long-distance sampling structure of the six-sided top hydraulic press includes a holding rod 1. One end of the holding rod 1 is hinged to a connecting rod 2. The end of the connecting rod 2 away from the holding rod 1 is detachably connected with a clamping member. A first driving member is arranged between the connecting rod 2 and the holding rod 1. The first driving member is used to drive the connecting rod 2 to rotate relative to the holding rod 1. The clamping member includes clamping claws 3. There are two clamping claws 3. A second driving member is arranged between the two clamping claws 3. One end of the clamping claw 3 is rotatably connected to a bracket 4. The end of the bracket 4 away from the clamping claw 3 is detachably connected to the side surface of the connecting rod 2.

[0024] Among them, a rubber sleeve 5 is sleeved on the end of the holding rod 1 away from the connecting rod 2, and the end of the rubber sleeve 5 is the holding end.

[0025] Specifically, the first driving member includes a piston rod 6 hinged to the side surface of the connecting rod 2. The end of the piston rod 6 away from the connecting rod 2 is connected to a cylinder 7. The cylinder 7 is rotatably connected inside the holding rod 1. A groove 8 is arranged at the position of the holding rod 1 corresponding to the connection of the cylinder 7.

[0026] The second driving member includes a double-acting cylinder 97 fixed between the two clamping claws 3. The side surface of the double-acting cylinder 97 is fixed to the bracket 4.

[0027] Furthermore, the cylinder 7 can drive the piston rod 6 to extend and retract. When the piston rod 6 extends, the piston rod 6 props up the connecting rod 2, and the connecting rod 2 rotates along the hinge point with the holding rod 1. Furthermore, the clamping angle between the connecting rod 2 and the holding rod 1 can be adjusted. When the clamping angle becomes larger, the distance between the clamping claw 3 and the rubber sleeve 5 becomes larger. Furthermore, the taking distance can be adjusted by driving the cylinder 7.

[0028] At the same time, the double-acting cylinder 97 can drive the clamping claws 3 to move. When the double-acting cylinder 97 props up, the distance between the two clamping claws 3 increases. Furthermore, the two clamping claws 3 can be placed on both sides of the sample. When the double-acting cylinder 97 is controlled to retract again, the two clamping claws 3 clamp on both sides of the sample, and then the sample is clamped.

[0029] Meanwhile, a stepped groove 10 is provided at the end of the connecting rod 2 close to the bracket 4. Threads are provided on the side of the stepped groove 10, and a locking nut 11 is externally threadedly connected to the threads. The bracket 4 is sleeved outside the connecting rod 2 and is clamped between the bottom of the stepped groove 10 and the locking nut 11. The bracket 4 is sleeved outside the connecting rod 2. When the locking nut 11 is screwed in, the bracket 4 is abutted between the bottom of the stepped groove 10 and the locking nut 11, and the bracket 4 is fixed. Furthermore, the bracket 4 is detachable, which is convenient for the overall storage of the clamping jaw 3, the connecting rod 2 and the holding rod 1.

[0030] Moreover, a control valve for the air cylinder 7 is fixed on the side of the holding rod 1. There are two control valves for the air cylinder 7, which are respectively located on both sides of the holding rod 1. One of the control valves for the air cylinder 7 is connected to the air cylinder 7, and the other control valve for the air cylinder 7 is connected to the double-acting air cylinder 97. The two control valves for the air cylinder 7 are arranged close to the rubber sleeve 5. The opening and closing of the air cylinder 7 and the double-acting air cylinder 97 are controlled by the control buttons of the control valves for the air cylinder 7. And the control valves for the air cylinder 7 are respectively arranged on both sides of the holding rod 1, so that it is convenient to operate while holding.

[0031] In this embodiment, the operating principle of the control valve for the air cylinder 7 to control the air cylinder 7 is based on the existing conventional air cylinder 7 control technology. Its control generally has two control buttons, one for controlling the air cylinder 7 to open and extend, and the other for controlling the air cylinder 7 to close and retract.

[0032] The working principle of the present utility model: After the six-sided top hydraulic press 101 finishes working, it is necessary to take out the sample placed inside it. For the existing technology, it is to use a person to sit on the six-sided top hydraulic press 101 and reach in through the hand to take it. In this solution, as Figure 1 shown, the clamping jaw 3 is inserted through the gap at the top of the six-sided top hydraulic press 101. The holding rod 1 is taken by hand, and the opening and closing of the air cylinder 7 are controlled by the control valve for the air cylinder 7. Furthermore, the rotation of the connecting rod 2 is adjusted, and the extending distance of the clamping jaw 3 is adjusted. Thus, when different workers take it, an appropriate length can be adjusted for easy taking. After the connecting rod 2 is rotated and adjusted, the connecting rod 2 and the clamping jaw 3 are inserted into the six-sided top hydraulic press. Then, the double-acting air cylinder 97 is controlled by the control valve for the air cylinder 7, and the clamping jaw 3 is opened to clamp the sample for taking.

[0033] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
