Abstract
The invention discloses a mold closing control assembly which is provided with an oil cylinder and used for pressing an oil hydraulic press. The assembly comprises a moving table, a main power assembly and an auxiliary power assembly, wherein the main power assembly is connected with the moving table; and the auxiliary power assembly is connected with the moving table and comprises an auxiliary oil cylinder, auxiliary power output equipment used together with the auxiliary oil cylinder and a plurality of electromagnetic ball valves used together with the auxiliary oil cylinder. Waste of output power of the auxiliary power assembly can be avoided effectively.
Description
Technical field
The present invention relates to put oil cylinder press down hydraulic press matched moulds control assembly.
Background technology
In prior art, hydraulic press is pressed down for large-tonnage being put oil cylinder, as shown in Figure 1-2, under self gravitation effect, the matched moulds that drops is accelerated for preventing traveling table 1 and each cylinder, cause equipment impaired, therefore adopt auxiliary power assembly 5 outputting power, the gravity of balancing activity platform 1 and each cylinder makes traveling table 1 and associated components steadily to decline matched moulds, auxiliary power assembly 5 is made up of auxiliary cylinder 31 and Solenoid ball valve 32 and auxiliary power output equipment 33, the decline process of balancing activity platform 1 and each cylinder, gravity does positive work, and auxiliary power assembly 5 pairs of traveling tables 1 do negative work, obviously, the now output of the merit of auxiliary power assembly 5 can cause unnecessary waste, how to avoid the waste of auxiliary power assembly 5 output work, it is a problem demanding prompt solution.
Summary of the invention
The object of this invention is to provide a kind of on put oil cylinder press down hydraulic press matched moulds control assembly, the waste of auxiliary power assembly output work in prior art can well be avoided.
The object of the invention is to be achieved through the following technical solutions:
The present invention propose a kind of on put oil cylinder press down hydraulic press matched moulds control assembly, comprise: traveling table, connect the active force assembly of traveling table, and connect the auxiliary power assembly of traveling table, auxiliary power assembly comprises: auxiliary cylinder and and auxiliary cylinder with the use of auxiliary power output equipment; Auxiliary power assembly also comprises: with auxiliary cylinder with the use of multiple Solenoid ball valves.
Active force assembly comprises: several master cylinders and several prefill valves.
Beneficial effect: the present invention can effectively avoid large-tonnage being put the waste that oil cylinder presses down hydraulic press auxiliary power assembly output work in matched moulds process.

Detailed description of the invention
As Fig. 3, embodiment provides one of the present invention puts oil cylinder and presses down hydraulic press matched moulds and control assembly, comprise: traveling table 1, with the auxiliary power assembly 6 being connected traveling table 1, auxiliary power assembly 6 comprises: auxiliary cylinder 31, multiple Solenoid ball valve 32, auxiliary power output equipment 33.
Folding part Solenoid ball valve 32, under self gravitation effect, traveling table 1 declines, auxiliary cylinder 31 is passive oil-filled, meanwhile, reacts on traveling table 1, traveling table 1 is steadily declined, and storage area gravitional force, make not need auxiliary power output equipment 33 to provide power, until matched moulds process completes.
Auxiliary power is only used for traveling table return.
Active force assembly 2 connects traveling table 1, and active force assembly 2 comprises master cylinder 21, prefill valve 22, active force output equipment 23.
After matched moulds process completes, by active force assembly 2 for traveling table 1 provides the power of pressurization.
The present invention is not limited thereto embodiment, the related realization assembly based on inventive concept is all in protection scope of the present invention.
