Abstract
The utility model relates to a piston rod of hydraulic press. The piston rod has low processing cost, moderate self weight and reasonable power requirement on equipment. The piston comprises a piston head and a piston body, and is characterized in that the piston body and the piston head are integrated, the piston head and the piston head are connected into a whole, a cavity is arranged in the piston body, and an opening of the cavity is positioned at the end part of the piston body.
Description
(1) technical field
The utility model relates to the accessory of hydraulic press, is specially the piston rod of hydraulic press.
(2) background technique
Existing piston rod comprises piston body 1 and piston head 2, connects with nut 3 between the two.This split type piston rod shortcoming is exactly to repeat the processing that identical manufacturing procedure is finished component, production cost of products is higher, and the piston rod employing is solid member, it is big to process required material consumption like this, cost is higher, the own wt of piston rod is big, and also high to the power requirement of equipment accordingly, energy loss was big when the user used.
(3) summary of the invention
It adopts split type at existing piston rod, piston body is a solid member, processing cost is higher, the bigger shortcoming of energy loss during use, the utility model provides another piston rod, as long as can process finished product once the cover operation, and materials are few, processing cost is lower, and energy loss was little when the user used.
The technical solution of the utility model is like this: it comprises piston head, piston body, it is characterized in that described piston body, piston head are as a whole, there is a cavity continuous as a whole piston head, piston body inside, and the opening of cavity is positioned at the end of piston body; It is further characterized in that the material of described piston rod is an alloy chilled nodular cast iron.
Piston body of the present utility model, piston head are processed into an integral body, and piston body is processed into intermediate hollow, not only save operation but also save raw material, thereby avoided repeating in the prior art manufacturing procedure, the cost of production height, the own wt of piston rod is also high to the power requirement of equipment greatly, the shortcoming that user's energy loss is big.
(4) description of drawings
Fig. 1 is the textural association figure of existing piston rod;
Fig. 2 is 1/4 sectional view of plan view of the present utility model.
(5) embodiment
See Fig. 2, the utility model comprises piston head 3, piston body 1, and both are as a whole, and there is a cavity 2 as a whole piston head 3, piston body 1 inside that links to each other, and the opening of cavity 2 is positioned at the end of piston body 1.Add first two sandboxes up and down in man-hour, the loam core, metal pattern places preheating in the drying room, the loam core, the metal pattern structural design according to piston rod in advance is good, then with the loam core, metal pattern is installed on drag box, on the side face of die cavity, coat the carbon ash behind the match grinding, again cope is installed on metal pattern, the molten iron that will reach the alloy nodular cast iron of predetermined temperature waters and casts from metal pattern, rising head up to metal pattern overflows molten iron, treat that the molten iron that overflows at the rising head place will cool off when shrinking in rising head, cast to hot topping again, go mould to take out foundry goods, deburring after the cooling, the processing of piston rod is so finished in fine finishing such as grinding.
Claims (2)
1, the piston rod of hydraulic press, it comprises piston head, piston body, it is characterized in that described piston body, piston head are as a whole, and there is a cavity as a whole piston head, the piston body inside that links to each other, and the opening of cavity is positioned at the end of piston body.
2, the piston rod of hydraulic press according to claim 1, the material that it is characterized in that described piston rod is an alloy chilled nodular cast iron.
