Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic presses, in particular to a hydraulic press. Background Art

[0002] A hydraulic press is a machine that uses liquid as a working medium and is made according to Pascal's principle to transfer energy to achieve various processes. A hydraulic press generally consists of three parts: the main machine, a power system, and a hydraulic control system. The patent name is: A hydraulic press with an installation mechanism (publication number: CN217124067U). The utility model patent discloses a hydraulic press, which is equipped with a connecting block, a rotating screw, a forward and reverse motor, a movable block, a positioning rod, a fixing plate, an anti-skid pad, and a slide. When the hydraulic press is used, the forward and reverse motors can be used to drive the two movable blocks to move relative to each other. When the two movable blocks move, the two fixed plates will move relative to each other, so as to fix and clamp the objects to be processed, avoiding the problem that the objects to be processed are easily affected by the punching pressure and jump off to cause safety hazards, thereby improving the practicality of the hydraulic press. However, the above hydraulic press can only punch thicker workpieces. That is to say, when the actual thickness of the workpiece is less than the thickness of the fixed plate, the workpiece cannot be punched normally after the extrusion plate moves down, and not all workpieces need to be punched comprehensively. The above hydraulic press cannot punch different parts of the workpiece, and it is difficult to improve its punching accuracy. Utility Model Content

[0019] Example: As shown in the attached Figure 1-4 As shown, the utility model is a hydraulic press, comprising a base 1, an extrusion plate 2, a hydraulic cylinder 3, and a support plate 4 arranged in sequence from bottom to top, guide columns 11 are fixed at the four corners of the top of the base 1, the extrusion plate 2 is provided with guide holes adapted to the guide columns 11, the top end of the guide column 11 is fixed to the support plate 4, the top end of the hydraulic cylinder 3 is fixed to the bottom of the support plate 4 by screws, and the bottom end of the hydraulic cylinder 3 is fixed to the top of the extrusion plate 2 by screws.

[0020] The rear end of the base 1 is provided with a material collection box 5, which can be fixed to the rear side wall of the base 1 by screws or directly welded to the rear side wall of the base 1. The top of the base 1 is provided with a push plate 6, and the base 1 is provided with a push mechanism 7 for pushing the push plate 6 to move forward and backward.

[0021] The pushing mechanism 7 can adopt a horizontally arranged cylinder. Preferably, the pushing mechanism 7 includes a driving motor 71 fixed on the base 1. The output shaft of the driving motor 71 is arranged vertically, and a crank 72 is installed on the output shaft. A connecting rod 73 is hinged on the crank 72. The end of the connecting rod 73 away from the crank 72 is hinged to the middle part of the rear end of the pushing plate 6. The length of the crank 72 is less than the length of the connecting rod 73. The crank 72 and the connecting rod 73 are both located above the base 1. The driving motor 71 rotates to drive the pushing plate 6 to move forward and backward, and the stamped workpiece can be pushed into the collecting box 5 for storage. There is no need for manual material retrieval. The entire material retrieval process is relatively time-saving and labor-saving, and is easy to apply in practice.

[0022] Furthermore, in order to ensure the stability of the push plate's forward and backward movement, at least two sliders 61 are provided at the bottom of the push plate 6, and a slide groove 12 adapted to the slider 61 is provided at the top of the base 1. The cooperation between the slider 61 and the slide groove 12 provides guidance for the forward and backward movement of the push plate.

[0023] A workpiece locking mechanism 8 is provided on the top of the base 1. Preferably, the workpiece locking mechanism 8 includes electric push rods 81 horizontally arranged at the left and right ends of the top of the base 1.

[0024] A pressing block 9 is provided at the bottom of the extrusion plate 2. The position of the pressing block 9 on the extrusion plate 2 is adjustable. A cross slide structure can be installed between the extrusion plate 2 and the pressing block 9, so that the position of the pressing block 9 can be arbitrarily adjusted in a plane area. Since the front and rear positions of the workpieces can be adjusted when the workpieces are locked, in order to reduce costs, only the left and right positions of the pressing block 9 can be adjusted. The pressing block 9 is provided with at least two through holes that penetrate the pressing block 9 on the left and right sides. The inner side of the through hole is provided with a guide rod 91 that penetrates the pressing block 9. The left and / or right ends of the through hole are provided with a guide sleeve 92 that is adapted to the guide rod 91.

The left and right ends of the guide rod 91 are provided with mounting seats 94, and the mounting seats 94 are fixed to the extrusion plate 2 by screws.

[0025] In order to further improve the stability of the pressing block, a sliding block may be arranged on the top of the pressing block, and a sliding groove adapted to the sliding block may be arranged at the bottom of the extrusion plate 2 , wherein the sliding groove is parallel to the guide rod 91 .

[0026] When the utility model is in use, the workpiece is placed on the base 1 and the workpiece is located between the two clamping plates 82. The two electric push rods 81 are controlled to extend. At this time, the two clamping plates 82 can be driven to move relative to each other, so that the workpiece can be clamped. The locking screw 93 is then loosened and the pressure block 9 is moved left and right. When the pressure block 9 moves to the ideal position, the locking screw 93 is tightened to fix the pressure block 9 on the guide rod 91. At this time, the pressure block 9 is fixed. The hydraulic cylinder 3 is then controlled to extend, so that the extrusion plate 2 and the pressure block 9 can be driven to move downward. By pressing the pressure block 9 downward, the workpiece can be stamped. After the workpiece is stamped, the two electric push rods 81 are controlled to shorten. At this time, the two clamping plates 82 can be driven to move in the opposite direction. The driving motor 71 is then controlled to rotate to push the stamped workpiece into the collection box 5. The stamped workpiece is pushed into the collection box 5 for storage. There is no need for manual material collection. The entire material collection process is relatively time-saving and labor-saving, and is easy to use in practice.
