Description

Technical Field

[0001] The invention belongs to the technical field of hydraulic forming machinery, and in particular relates to a multi-column rotary feeding hydraulic press. Background Art

[0002] Perforating charges are explosives used to penetrate casing, cement sheath and formation during the perforating process. The round-trip feeding process currently used in the processing of perforating charges has the following defects:

[0003] 1. The round-trip feeding process used in the past resulted in a long waiting time for the press to feed materials, low production efficiency, and large energy loss;

[0004] 2. In the past, the pressing machine used a 4-column press with a large table, no less than 600mm×600mm, which took up more space, while the effective occupied area of ​​the perforating bullet (finished product) was small (less than 100mm in diameter), resulting in a waste of press manufacturing materials;

[0005] 3. The compression molding of perforating bullets is a dangerous and explosive material processing. An isolation device is required between the operator and the press. This makes it difficult to design the operator and the working surface (the center point of the press table) within the ideal range, which can easily cause operator fatigue, and the operating space is relatively tight, which is not conducive to humanized operation;

[0006] Therefore, a multi-column rotary feeding hydraulic press is proposed to solve the above problems. Summary of the invention

[0007] The purpose of the present invention is to provide a multi-column rotary feeding hydraulic press to solve the existing problems.

[0008] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0009] The present invention discloses a multi-column rotary feeding hydraulic press, comprising an upper crossbeam, a lower crossbeam and a column fixed between the upper crossbeam and the lower crossbeam, a pressing oil cylinder is arranged on the upper surface of the upper crossbeam, an output end of the pressing oil cylinder passes through the upper crossbeam, a movable slider is fixedly connected to the output end of the pressing oil cylinder, a convex die is arranged on the lower surface of the movable slider, the movable slider is sleeved on the peripheral side surface of the column, the movable slider and the column are slidably matched, a rotating disk is rotatably connected to the peripheral side surface of the column, a gear ring is arranged on the lower surface of the rotating disk, a concave die is fixed to the edge of the upper surface of the rotating disk, a cavity is arranged in the lower crossbeam, an ejection oil cylinder is arranged in the cavity, an ejection rod is fixed to the output end of the ejection oil cylinder, a stepping motor is fixedly connected to one side surface of the lower crossbeam, and a gear is fixedly connected to the output end of the stepping motor.

[0010] In one of the embodiments, the upper crossbeam and the lower crossbeam are fixedly connected via a column, and the cross-sections of the upper crossbeam, the lower crossbeam and the movable slider are all triangular.

[0011] In one embodiment, the position, shape and size of the male mold are adapted to those of the female mold, and the male mold and the female mold cooperate with each other.

[0012] In one of the embodiments, the position, shape and size of the central ejection hole of the die are adapted to the ejection rod, and the ejection rod cooperates with the central ejection hole of the die.

[0013] In one embodiment, the shape and size of the gear ring are adapted to the gear, and the gear ring and the gear are meshed with each other.

[0014] In one embodiment, three columns are provided between the upper crossbeam and the lower crossbeam, and the centers of the cross sections of the three columns cut by the same horizontal plane are arranged in a triangle.

[0015] The present invention has the following beneficial effects:

[0016] When processing perforating bullets and dangerous explosives, first, a single column is formed on the side close to the explosion-proof wall as the rotating axis of the feeding mechanism. The feeding mechanism spans the explosion-proof wall and is provided with multiple stations. By rotating it, different work stations are switched, and the cycle of pressing and loading can be realized simultaneously on the multiple stations of the turntable, which shortens the previous round-trip movement time and expands the operation space. Moreover, the stepper motor has a frequency conversion function, and the speed and feed rate are adjustable, and the operation is stable. Within a certain range, the forming process requirements of perforating bullets of different types can be met by replacing the convex and concave dies. The stepper motor stops, the pressing cylinder is pressed down, and the movable slide moves downward, so that the convex and concave dies are closed up and down, and the workpiece is formed into a perforating bullet. The pressing cylinder drives the punch upward to the upper dead point, and the ejection cylinder drives the ejection rod upward to eject the perforating bullet out of the concave die, and finally the output end of the ejection cylinder moves downward to the lower dead point.

[0017] The invention has reasonable structural design, compact structure, small space occupation, high production efficiency, reduces the labor intensity of workers, and is easy to realize the streamlined operation of perforating bullet molding. At the same time, it reduces unnecessary working surface of the press and saves manufacturing materials.

[0018] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
