Abstract

The invention discloses a distributing vehicle device capable of realizing bidirectional pressing, which can effectively solve the problems of uneven compactness and difficult forming of green bricks caused by uneven upper and lower stress of materials when a unidirectional hydraulic brick making forming machine presses green bricks with larger height sizes. The process comprises the following steps: an upper oil cylinder is arranged at the brick pressing part of the material distribution vehicle, the bottom of the upper oil cylinder is connected with an upper wear-resisting plate of the material distribution vehicle, and a piston rod of the upper oil cylinder is connected with an upper punch; in the brick pressing process, when the piston rod of the upper oil cylinder is in a contraction state, upward one-way pressing of the main oil cylinder of the brick machine is realized; when the piston rod of the upper oil cylinder is in an extending state, the upper punch presses downwards along the guide block; through the extension and contraction of the piston rod of the upper oil cylinder, the unidirectional pressing of the full-automatic hydraulic forming machine can be realized, and the bidirectional pressing can also be realized; the piston rod of the upper oil cylinder is always in a contraction state in the moving process of the distributing vehicle, and the bottom surface of the upper punch connected with the piston rod is level to the bottom surface of the wear-resisting plate so as to prevent the distributing vehicle from being stuck in the moving process.

Description

Cloth vehicle device capable of realizing bidirectional pressing

Technical Field

The invention relates to a pressing mode of a full-automatic hydraulic forming machine, in particular to a bidirectional pressing mechanism of a hydraulic brick machine.

Background

The hydraulic brick machine in the prior art is generally used for one-way pressing, when the brick is pressed in one way, the pressure inside a green brick is unevenly distributed, the pressed surface is dense, the non-pressed surface is loose, and the phenomena of layering and dead angles can occur. Especially when pressing bricks which are high in thickness and difficult to mold, because the molding pressure is gradually reduced in the blank, if one-way pressing is adopted, the surface of the blank far away from the convex die is loose, and the phenomena of layering, corner falling and the like are easy to occur, and in order to ensure that the pressure and the compactness of the brick blank are uniform, two-way pressing is adopted. The two-way pressing is divided into two conditions of simultaneous pressing and sequential pressing: when two sides are pressurized simultaneously, the phenomena of low pressure area and dead angle at the bottom can be eliminated, but the density of the middle part of the green brick is lower; when two sides are pressurized successively, a gap is reserved between the two pressurizing, which is beneficial to the discharge of air and ensures that the pressure and the compactness of the whole green brick are relatively uniform.

Disclosure of Invention

the invention aims to provide a material distribution vehicle device which can perform unidirectional pressing and bidirectional sequential pressing. The device is suitable for pressing bricks which are large in thickness and size and difficult to form, and the pressed green bricks are uniform in pressure and compactness.

To achieve the above object, the present invention is achieved by:

(1) The upper oil cylinder is arranged at a brick pressing part of the distributing vehicle and moves along with the distributing vehicle, the bottom of the upper oil cylinder is connected with an upper wear-resistant plate through a bolt, a piston rod is connected with an upper punch through a bolt, and the upper wear-resistant plate and a lower wear-resistant plate are fixed on the distributing vehicle; (2) in the brick pressing process, when a piston rod of an upper oil cylinder is in a contraction state, the bottom surface of an upper punch is connected with the bottom surface of a lower wear-resisting plate to form a whole wear-resisting plate so as to realize one-way pressing of a main oil cylinder, and when the upper oil cylinder is in an extension state, the upper punch presses downwards along a guide block; the unidirectional pressing of the full-automatic hydraulic forming machine can be realized through the stretching and contracting movement of the piston rod of the upper oil cylinder, and the bidirectional pressing can also be realized. (3) In order to prevent the phenomenon of blocking in the moving process of the distributing vehicle, the piston rod of the upper oil cylinder is always in a contraction state when the distributing vehicle moves, and the bottom surface of the upper punch connected with the piston rod is level with the bottom surface of the wear-resisting plate.

Detailed Description

The best embodiment is as follows:

(1) cloth car 1 is three station workstations, goes up jar 3 and installs the pressure brick position at cloth car 1, follows cloth car 1 and moves together, goes up 3 bottoms of jar and is connected with last antifriction plate 5 through the bolt, and the piston rod is connected with upper punch 7 through the bolt, goes up antifriction plate 5 and wear-resisting plate 8 down and fixes on cloth car 1. (2) In order to prevent the blocking phenomenon in the movement process of the distributing vehicle 1, the piston rod of the upper oil cylinder 3 is always in a contraction state, and the bottom surface of the upper punch 7 connected with the piston rod is level with the bottom surface of the lower wear-resisting plate 8. (3) The material distribution vehicle 1 moves to a brick pressing position, the main oil cylinder 2 is pressed firstly, and when a piston rod of the upper oil cylinder 3 is in a contraction state, the bottom surface of the upper punch 7 is connected with the bottom surface of the lower wear-resisting plate 8 to form a whole wear-resisting plate so as to realize the one-way pressing of the main oil cylinder 2; after the main oil cylinder 2 is pressed, the upper punch 7 is pressed downwards along the guide block 6 under the action of the upper oil cylinder 3, the linear displacement sensor 4 is arranged in the upper oil cylinder 3 and can detect and feed back the stroke of the upper punch 7, and after the pressing is finished, the piston rod of the upper oil cylinder 3 retracts until the bottom surface of the upper punch 7 is exactly level to the bottom surface of the lower wear-resisting plate 8; (4) the sequential bidirectional pressing of the full-automatic hydraulic forming machine can be realized through the extension and contraction states of the piston rod of the upper oil cylinder 3. (5) After the brick pressing is finished, the material distribution vehicle 1 moves to the brick clamping position, and the main oil cylinder 2 moves upwards to eject a green brick.
