specific Embodiment

[0015] This embodiment is the automatic compensation and adjustment steps of the injection volume of the injection cylinder:

[0016] Fill Piston Stop Position:

[0017] The position of the injection piston stopper needs to be adjusted accordingly according to the mold, and it will be automatically adjusted according to the thickness of the green body during automatic continuous operation. After pressing out a normal green body, enter the current injection piston stopper in this column Position for memory. When using the same mold again, readjust the current position of the injection piston stopper according to the data memorized in this column. Setting range: 0.0-300.0 Injection waiting time:

[0018] Set the waiting time for the injection action to start after the upper and lower touch is closed.

[0019] Injection time:

[0020] Set the monitoring time of the injection action, if it exceeds this time, it will be abnormal. Green body thickness correction amount:

Abstract

The invention discloses a material injecting device of a magnetic material hydraulic press, which comprises a feed cylinder, an agitating device and a material injecting cylinder. An agitating device is arranged in the feed cylinder; the material injecting cylinder is connected with the feed cylinder; an automatic compensation and adjustment device for material injection amount is arranged on the material injecting cylinder and adopts the structure that a piston rod is arranged on two sides of the material injecting cylinder respectively; both the piston rod and the piston rod of the material injecting cylinder are fixedly connected with a slide block; and the slide block is also connected with an adjusting device. The material injection amount can be adjusted automatically by the automatic compensation and adjustment device for the material injection amount, so that the material amount required for the formation of finished products in a die cavity is satisfied; the integrative formation of products overflowed and damaged by excessive material amount and the no-formation of the products caused by lower material amount are prevented, and the production efficiency of the products is improved.

Description

technical field [0001] The invention relates to a hydraulic machine, in particular to a material injection device of a magnetic material hydraulic machine which can automatically adjust the material injection amount. Background technique [0002] At present, the injection of magnetic material hydraulic presses in the market is a vertical structure injection device. The position of the limit stopper of this structure is manually adjusted, which has the disadvantages of low accuracy and long adjustment process. Affecting production efficiency also affects the pass rate of products due to the uncertainty of the amount of injection. Contents of the invention [0003] The main task of the present invention is to provide a material injection device for a magnetic material hydraulic press, specifically a material injection device for a magnetic material hydraulic press that can automatically adjust the injection amount. [0004] In order to solve the above technical problems, a ...
