Abstract
The utility model discloses a matched structure of a plunger and a large cushion block. A groove is arranged at the center of the top part of the plunger; an insulated plate is arranged in the groove; a large cone end of the large cushion block presents a step shape and is sleeved with an insulated ring matched with the groove at the top part of the plunger; and the large cone end of the large cushion block sleeved with the insulated ring is embedded into the groove provided with the insulated plate and is fixed with the plunger. The matched structure is more stable and reliable in use, reduces and even eliminates cracking of the insulated plate, shortens downtime, reduces hidden danger of devices in production and effectively increases production efficiency and production stability.
Description
Technical field
The utility model belongs to the film ultra-hard material synthesizer technical field, especially relates to a kind of piston on the man-made diamond pressing machine and fit structure of big cushion block of being used for.
Background technology
Piston is to adopt the piston center to be provided with the assembling mode of alignment pin with cooperating of big cushion block in the existing man-made diamond pressing machine, as shown in Figure 1, this fit system is in diamond high pressure building-up process, make insulation board 3 very easy the extruding of installing between big cushion block 2 and piston 1 end face cause cracking from periphery, the stable operation of the equipment of giving brings hidden danger, frequent replacing insulation board also causes bigger influence to the available machine time of equipment simultaneously, influences production efficiency, causes very big loss.
Summary of the invention
For addressing the above problem, the purpose of this utility model provides the fit structure of more reliable and more stable piston of a kind of use and big cushion block.
For achieving the above object, the utility model adopts following technical scheme:
The fit structure of a kind of piston and big cushion block, its top land central authorities are provided with groove, insulation board is housed in the groove, the auger end of big cushion block is step-like, the auger end is with the dead ring that matches with the top land groove, and the big cushion block auger end that is with dead ring is inlaid in the groove that insulation board is housed and with piston and fixes.
Owing to adopt aforesaid technical scheme, the utlity model has following superiority:
The fit structure of this piston and big cushion block, it can guarantee that in use insulation board can not extrude from the groove of piston behind pressurized, and the gap between big cushion block, dead ring and the piston guaranteed the positioning accuracy of big cushion block in piston central authorities, and is therefore in use more reliable and more stable; Reduce even stop the cracking of insulation board, reduce greatly because of change the downtime that insulation board causes and produce in hidden trouble of equipment, effectively enhance productivity and production stability.
