Description

Technical Field

[0001] The invention relates to the technical field of mechanical processing, in particular to a mechanical processing device for mechanical manufacturing. Background Art

[0002] In the field of mechanical manufacturing, a variety of mechanical processing devices are widely used, among which shearing machines are particularly critical. Shearing machines integrate core components such as CNC systems, transmission systems and cutting systems. During its operation, the steel plate is required to move forward intermittently. This displacement is usually precisely controlled by a pushing device. Traditional pushing devices are mainly divided into two types: push plate pushing and roller pushing: Push plate pushing relies on the push plate to directly contact one end of the steel plate to achieve driven transportation of large steel plates; roller pushing uses the cooperation of rollers rotating up and down, which is more suitable for pushing small steel plates. No matter which pushing method is used, the work flow of the shearing machine requires that the sheet material is accurately pushed into place before the pressing assembly close to the tool can be started to perform the pressing operation and then cut. However, this process is less efficient because the existing pressing assemblies mostly adopt a flexible design. When pressing, after the pressing foot first contacts the sheet material, it is necessary to further press down the pressing push plate to compress the spring in between until the sheet material is firmly pressed. This step significantly increases the operation time. For this reason, we propose a mechanical processing device for mechanical manufacturing. Summary of the invention

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Example 1: Please refer to Figure 1-Figure 6 The present invention provides a technical solution: a mechanical processing device for mechanical manufacturing, comprising a shearing machine body 1 and a tool 11 arranged in the shearing machine body 1, and also comprising:

[0037] A material pressing push plate 2 is slidably arranged on the shearing machine body 1, and a plurality of material pressing feet 3 are evenly and equidistantly arranged on one side of the material pressing push plate 2, and a spring 4 is arranged between the material pressing foot 3 and the material pressing push plate 2;

[0038] A driving assembly 5 is provided on the shearing machine body 1 and is used to drive the pressing push plate 2 and the pressing foot 3 to move downward to press the material plate;

[0039] The linkage component 6 is arranged on the shearing machine body 1, and the pressing push plate 2 moves downward to drive the pressing foot 3 to move downward, and at the same time, the linkage component 6 drives the pressing foot 3 to move with the material plate and press the material plate;

[0040] Specifically, in the process of the traditional material pushing device pushing the sheet material, the device starts the hydraulic push rod 53 to drive the pressing foot 3 to move down and press the sheet material while following the movement of the sheet material, and then when the sheet material stops, the pressing foot 3 also presses and fixes the sheet material, thereby improving the working efficiency;

[0041] The device uses a U-shaped support plate to move synchronously with the press foot 3 and simultaneously fix the material plate, thereby improving the fixing effect of the material plate and preventing the material plate from being subjected to excessive friction during the movement;

[0042] This device can limit the pressing foot 3 to one side of the tool 11 by inserting the bolt 68 into the limiting hole 69, so that the device body can be restored to the state of the existing shearing machine pressing device to adapt to more situations, thereby improving the adaptability of the device.

[0043] The driving assembly 5 includes a sliding plate 51 arranged on the shearing machine body 1, the sliding plate 51 is connected to the material pressing push plate 2, and a guide rod 52 is fixedly connected to the sliding plate 51, one end of the guide rod 52 slides through the shearing machine body 1 to guide and limit the movement of the sliding plate 51, and a hydraulic push rod 53 is fixedly connected to the shearing machine body 1, and the extended end of the hydraulic push rod 53 is fixedly connected to the sliding plate 51. Starting the hydraulic push rod 53 drives the sliding plate 51 to move, and then drives the material pressing push plate 2 to move.

[0044] A guide rod 2 54 is fixedly connected to one side of the material pressing push plate 2, one end of which slides through the sliding plate 51, and one end of which is fixedly connected to the limit plate 55. A spring 2 56 is sleeved on the guide rod 54, and its two ends are respectively in contact with the sliding plate 51 and the limit plate 55. When the material pressing push plate 2 moves relative to the sliding plate 51, the spring 2 56 is compressed and contracted to provide a self-restoring elastic force for it;

[0045] One end of the press foot 3 is fixedly connected to a guide rod 3 57, and one end of the guide rod 3 57 slides through the press push plate 2 to guide and limit the sliding of the press foot 3. A spring 1 4 is sleeved on the guide rod 3 57 and its two ends are respectively fixedly connected to the press foot 3 and the press push plate 2. Specifically, in the process of moving the press push plate 2 downward, the press foot 3 first contacts the material plate, and then continues to move the press push plate 2 downward to compress the spring 1 4 to provide a continuous and stable downward pressure for the press foot 3.

[0046] The linkage assembly 6 includes a rectangular plate 58 fixedly connected to the shearing machine body 1, a guide groove 59 is opened on the rectangular plate 58, and a hollow column 61 is fixedly connected to the end of the pressing and pushing plate 2, and a cylindrical protrusion 62 is slidably connected to the hollow column 61. One end of the cylindrical protrusion 62 is located in the guide groove 59. The pressing and pushing plate 2 is moved downward, driving the cylindrical protrusion 62 to slide along the guide groove 59 to drive the pressing and pushing plate 2 to follow the movement of the material plate.

[0047] The guide groove member 59 includes an inclined groove 63 provided on a rectangular plate 58, one end of a cylindrical protrusion 62 is located in the inclined groove 63 and is slidably connected to the inner wall thereof, and the downward movement of the material pressing push plate 2 drives the cylindrical protrusion 62 to slide along the inclined groove 63, thereby driving the material pressing push plate 2 to move while compressing the spring 2 56 and driving the material pressing foot 3 to move with the material plate;

[0048] A vertical slide groove 64 connected to the inclined slide groove 63 is provided on the rectangular plate 58. The vertical slide groove 64 is designed to have a depth greater than that of the inclined slide groove 63. One end of the cylindrical protrusion 62 is located in the hollow column 61 and is fixedly connected to a spring three 65. One end of the spring three 65 is fixedly connected to the inner wall of the hollow column 61. When the cylindrical protrusion 62 is located in the inclined slide groove 63, the spring three 65 is in a compressed state. When the pressing material pushing plate 2 is moved downward to drive the cylindrical protrusion 62 to slide along the inclined slide groove 63 to the vertical slide groove 64, the spring three 65 is reset to drive the cylindrical protrusion 62 to extend and embed into the vertical slide groove 64. Then, the pressing material pushing plate 2 is moved upward to drive the cylindrical protrusion 62 to move along the vertical slide groove 64.

[0049] A horizontal slide groove 66 is provided on the rectangular plate 1 58, and the two ends of the horizontal slide groove 66 are respectively connected to the vertical slide groove 64 and the inclined slide groove 1 63, and an inclined surface 67 is provided in the horizontal slide groove 66. When the upward pressing push plate 2 drives the cylindrical protrusion 62 to slide along the vertical slide groove 64 into the horizontal slide groove 66, the spring 2 56 is reset to drive the cylindrical protrusion 62 to slide along the horizontal slide groove 66 to drive the pressing foot 3 to reset, and at the same time, the inclined surface 67 is used to push the cylindrical protrusion 62 to move and compress the spring 3 65 at the same time;

[0050] Specifically, by starting the hydraulic push rod 53 to push the sliding plate 51 downward, the material pressing push plate 2 is then driven to move downward. At this time, the cylindrical protrusion 62 slides along the inclined slide groove 1 63, thereby driving the material pressing push plate 2 to move with the material plate while pressing down. When the cylindrical protrusion 62 moves into the vertical slide groove 64, the spring three 65 resets and drives the cylindrical protrusion 62 to embed into the depth of the vertical slide groove 64. At this time, the material pressing foot 3 also presses the material plate tightly, and the material plate also stops moving. Then the tool 11 cuts the material plate. When the tool 11 moves upward, the hydraulic push rod 53 is started to drive the material pressing push plate 2 to move upward, and the cylindrical protrusion 62 moves to the bottom along the vertical slide groove 64. After reaching the bottom, the spring two 56 resets and drives the cylindrical protrusion 62 to slide along the horizontal slide groove 66 to the end of the inclined slide groove 1 63, and at the same time drives the material pressing push plate 2 and the material pressing foot 3 to move and reset. In this process, the cylindrical protrusion 62 is pushed by the inclined surface 67 to compress the spring three 65 to provide it with self-restoring elastic force.

[0051] The sliding plate 51 is connected with a bolt 68 through a thread, and a limiting hole 69 is provided on the guide rod 54. When the pressing plate 2 is moved to drive the cylindrical protrusion 62 to embed into the vertical slide groove 64, the limiting hole 69 is aligned with the bolt 68, and then the bolt 68 is rotated to embed into the limiting hole 69 to lock the pressing plate 2, and then the pressing foot 3 can be limited to the side of the tool 11, so that the main body of the device can be restored to the state of the existing shearing machine pressing device to adapt to more situations, thereby improving the adaptability of the device.

[0052] A guide rod 71 is fixedly connected to the shearing machine body 1, and a U-shaped carriage 72 is slidably connected to the guide rod 71, and the U-shaped carriage 72 is located below the pressing foot 3 and cooperates with it to press the material plate;

[0053] A guide rod 5 73 is fixedly connected to the U-shaped support plate, and one end of the guide rod 5 73 slides through the material pressing push plate 2. When the material pressing push plate 2 is moved, the guide rod 5 73 is used to drive the U-shaped support plate to move.

[0054] Example 2: Please refer to Figure 1-Figure 8 , the present invention provides a technical solution: Example 2 is another specific implementation of the linkage component 6 in Example 1;

[0055] The linkage assembly 6 includes a rectangular plate 74 fixedly connected to the shearing machine body 1, and a second inclined groove 75 is provided on the rectangular plate 74, and a cylindrical protrusion 62 is fixedly connected to the end of the pressing and pushing plate 2, and one end of the cylindrical protrusion 62 is located in the second inclined groove 75 and is slidably connected to the inner wall thereof. Pressing the pressing and pushing plate 2 downward drives the cylindrical protrusion 62 to slide along the second inclined groove 75 to drive the pressing foot 3 to move with the material plate;

[0056] A locking member 77 is provided on the material pressing and pushing plate 2 for locking the guide rod 3 57;

[0057] Specifically, by starting the hydraulic push rod 53, the sliding plate 51 is pressed down, and then the material pressing push plate 2 is driven to move downward. At this time, the cylindrical protrusion 62 slides along the inclined slide groove 63, thereby driving the material pressing push plate 2 to move with the material plate while pressing down. Subsequently, the material pressing foot 3 presses the material plate, and the material plate also stops moving. Then the tool 11 cuts the material plate. When the tool 11 moves up, the electric push rod 82 is started first to drive the extrusion plate 78 to lock the guide rod three 57, and then the hydraulic push rod 53 is started to drive the material pressing push plate 2 to move up to drive the material pressing foot 3 to reset, and then the electric push rod 82 is started to release the guide rod three 57.

[0058] The locking member 77 includes a squeeze plate 78 slidably connected to the material pressing push plate 2, and an arc groove 79 is provided on one side of the squeeze plate 78. A strip plate 81 is slidably connected to the material pressing push plate 2, and the squeeze plate 78 is fixedly connected to the strip plate 81. An electric push rod 82 is fixedly connected to the material pressing push plate 2, and the extended end of the electric push rod 82 is fixedly connected to the strip plate 81.

[0059] The inner wall of the arc groove 79 is designed with rubber material to increase the friction between the arc groove 79 and the guide rod 3 57, thereby improving the locking effect.
