Problems solved by technology

The oil inlet of the cylinder with this structure is on the cylinder below the piston. Because the air is lighter than the oil, the air in the cylinder cannot be discharged cleanly when the piston moves from top to bottom, so it stays in the cylinder all the time. , which affects the accurate measurement of the oil pressure sensor (pre

Example Embodiment

[0011] The embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0012] The upper end of the screw rod 1 is connected with the power source crank connecting rod mechanism on the powder forming machine. The ball handle at the lower end of the screw rod 1 is fixed on two positioning keys through a pin, and the two positioning keys are fixed under the ball cover 2, and the lower end of the ball handle Cooperating with the ball seat 4 in the slider 3, it swings forward and backward in the ball seat without being seized. The ball cover 2 is fixed on the upper end surface of the slider 3 with screws.

[0013] A pressure controller is installed on the bottom plate 10, and the valve seat on the pressure controller communicates with the measuring cylinder 7 (not shown in the figure).

[0014] A cavity is machined under the original slider. The measuring cylinder 7 is screwed to the inner cavity of the sliding block 3 and the b...

Abstract

The present invention provides a pressure testing oil cylinder mechanism of a powder shaping machine consisting of a driving screw matching with a ball seat in the sliding block, an oil cylinder fixed on the sliding block and the soleplate, an air cylinder body with a piston is fixed on the oil cylinder, an air cylinder piston matching with a guider actively and that is fixed on a connection board. Said oil cylinder is a cylinder for measuring that is fixed on the sliding block and the soleplate, and a measuring piston is provided in the inner chamber, and also the oil cylinder matches with the air cylinder piston and the air cylinder body. The pressure of the powder shaping machine can be measured accurately by the oil pressure sensor of the pressure controller positioned on the soleplate, even though moving direction of the measuring piston is converted from the upper to the lower comparing the original moving direction and all the air in the measuring oil cylinder is discharged in the moving state. As a result, the pressure of the pressed objects is controlled by a pressure controller for adjusting, controlling and inputting the pressure of the measuring oil cylinder.

Description

technical field [0001] The invention relates to an important part in a powder forming machine, a powder forming machine pressure measuring oil cylinder mechanism used to measure and adjust the oil pressure during forming by using a measuring oil cylinder to keep the oil pressure stable during the forming and pressing process of products. Background technique [0002] During the entire production and pressing process of the powder forming machine, in order to ensure the stable quality of the pressed product, improve the qualified rate of the product, reduce the production cost, and prolong the service life of the powder forming machine, it is necessary to install a pressure controller on the powder forming machine for adjustment and control. , Input the oil pressure in the measuring oil cylinder to make it stable and no sudden change will occur. [0003] Patent No. CN200520101754.2 "Powder Forming Machine Pressure Controller" provides a pressure controller, but the cylinder s...
