Description

Technical Field

[0001] The utility model relates to the field of excavators, in particular to a processing device for an excavator motor main board. Background Art

[0002] An excavator, also known as excavating machinery, also known as a power shovel, is an earthmoving machine that uses a bucket to excavate materials above or below the machine surface and loads them into a transport vehicle or unloads them to a stockpile.

[0003] As Figure 1 shown is an excavator motor main board 10. The motor main board belongs to a special-shaped sheet metal structure, which is composed of an arc plate 11 and a tangent flat plate 12.

[0004] In the process of implementing the present utility model, the inventor found that there are at least the following problems in the prior art:

[0005] At present, there are two processing methods for forming the motor main board. One is to divide the motor main board into a flat plate and an arc plate, form them separately and then combine and weld them. This process has accurate forming, but low efficiency and potential quality hazards caused by welding defects. The other is to form by two-time die pressing. This process is much more efficient than welding, but due to the inconsistent positioning during the second die pressing and the first die pressing, the product forming is inaccurate, and the deformation amount during the second forming is difficult to control, resulting in the opening of the motor main board being much larger than the actual requirement.

[0006] Therefore, a processing device for an excavator motor main board is needed to at least partially solve the above technical problems. Summary of the Invention

[0049] The utility model provides a processing device for an excavator motor mainboard, wherein the processing device 100 can be applied to the excavator field, such as for molding an excavator motor mainboard 10, and can solve the problem of low efficiency or poor molding quality of the existing molding technology of the motor mainboard 10.

[0050] First, if Figure 2 As shown in the figure, which will be described below, the processing object of the processing device 100 of the present invention is the mainboard processing piece 20. The mainboard processing piece 20 can be formed into the motor mainboard 10 at one time by the processing device 100. The mainboard processing piece 20 is a flat plate after the motor mainboard 10 is horizontally unfolded. Among them, the motor mainboard 10 is a prior art device, which belongs to a special-shaped sheet metal structure, which is composed of a circular arc plate 11 and a tangent plate 12.

[0051] The utility model provides a processing device 100 for an excavator motor mainboard. In a preferred embodiment, Figure 3 and Figure 4 As shown, Figure 3 is a schematic diagram of a processing device 100 according to an embodiment of the present utility model; Figure 4 for Figure 3 The processing device 100 is shown in a side view, wherein the left movable mold 121 and the right movable mold 122 are partially perspective processed. The processing device 100 may include a frame 110, a left movable mold 121, a right movable mold 122 and a pressing mold 130.

[0052] The frame 110 serves as a supporting mechanism of the processing device 100 and is used to install the left movable mold 121 and the right movable mold 122. The left movable mold 121 and the right movable mold 122 can rotate synchronously in opposite directions relative to the frame 110. The pressing die 130 serves as an actuator for applying pressure, and is used to apply force downward to the mainboard processing piece 20, and cooperate with the left movable mold 121 and the right movable mold 122 to bend the mainboard processing piece 20, and form the motor mainboard 10 at one time.

[0053] Specifically, the frame 110 for installing the left movable mold 121 and the right movable mold 122 is as shown in FIG. Figure 3 As shown, the frame 110 may include a base plate and two vertical plates 111 arranged on the base plate and spaced apart along the front-to-back direction, such as two vertical vertical plates 111 arranged side by side.

[0054] like Figure 4As shown, a left movable mold 121 and a right movable mold 122 arranged symmetrically are provided on a frame body 110. Among them, there is no strict restriction on the installation positions of the left movable mold 121 and the right movable mold 122 on the frame body 110. For example, it can be on one side outside the frame body 110, or inside the frame body 110, such as between two vertical plates 111. The left movable mold 121 and the right movable mold 122 can rotate synchronously relative to the frame body 110 in opposite rotation directions in a vertical plane. For example, when the left movable mold 121 rotates clockwise relative to the frame body 110 in a vertical plane, the right movable mold 122 rotates counterclockwise synchronously relative to the frame body 110 in a vertical plane. Or, when the left movable mold 121 rotates counterclockwise relative to the frame body 110 in a vertical plane, the right movable mold 122 rotates clockwise synchronously relative to the frame body 110 in a vertical plane.

[0055] Among them, the left movable mold 121 and the right movable mold 122 can be rotationally connected to the frame body 110 through a pivot 113 extending in the front-rear direction to achieve rotation relative to the frame body 110.

[0056] Among them, both the left movable mold 121 and the right movable mold 122 include a mold body 123 and a concave wall surface 124 provided on the opposite side (inner side) of the mold body 123. The wall surface 124 can include an arc surface portion 125 adapted to the arc plate shape of the motor main board and a flat surface portion 126 adapted to the tangent flat plate shape of the motor main board. The flat surface portion 126 and the arc surface portion 125 are smoothly transitionally connected.

[0057] In addition, the mold bodies 123 of the left movable mold 121 and the right movable mold 122 can both be individual block structures, or can be an integral structure formed by connecting multiple blocks together.

[0058] A pressing mold 130 for pressing down the main board workpiece 20 can move up and down relative to the frame body 110 in the vertical direction. The pressing mold 130 is a water droplet-shaped block structure adapted to the bent shape of the motor main board 10 (i.e., Figure 1 the shape shown in (a) of

[0059] Similarly, the pressing mold 130 can also be an individual block structure, or can be an integral structure formed by connecting multiple blocks together.

[0060] Reference Figure 6, when the processing device 100 is working, when the pressing die 130 presses down the main board workpiece 20 and moves to the target position W1, the left movable die 121 and the right movable die 122 synchronously rotate from the initial position W3 to the predetermined position W2 under the pressure of the main board workpiece and the pressing die 130 respectively. A channel adapted to the bending shape and size of the motor main board is formed between the left movable die 121 and the right movable die 122 at the predetermined position W2 and the pressing die 130 at the target position W1, so that the main board workpiece 20 is bent and formed into the motor main board 10.

[0061] Among them, when in the initial position W3, the left movable die 121 and the right movable die 122 are surrounded by a receiving space for receiving the pressing die 130, so that the pressing die 130 can enter the receiving space after starting to press down the main board workpiece.

[0062] According to the processing device 100 of the present utility model, including structures such as a left movable die 121, a right movable die 122 and a pressing die 130, by pressing down the main board workpiece with the pressing die 130, and at the same time the left movable die 121 and the right movable die 122 rotate, and cooperate with the pressing die 130 to finally jointly form a channel adapted to the bending shape and size of the motor main board. At this time, the left movable die 121, the right movable die 122 and the pressing die 130 jointly press closely against the main board workpiece, and bend the main board workpiece to form it into the motor main board, realizing one-time processing and forming of the motor main board. And because it is one-time bending and forming of the whole main board workpiece, the forming quality is good.

[0063] Furthermore, when the pressing die 130 moves upward from the target position W1, the motor main board wrapped on the pressing die 130 rises together. And when the pressing die 130 moves upward to a position where it is disengaged from the left movable die 121 and the right movable die 122, the left movable die 121 and the right movable die 122 can be reset and automatically rotate to their respective initial positions W3.

[0064] Continue to refer to Figure 3 , in order to enable the left movable die 121 and the right movable die 122 to automatically rotate to their respective initial positions W3, the processing device 100 may further include a reset mechanism. The reset mechanism is arranged on the frame 110 corresponding to the left movable die 121 and the right movable die 122, and is used to drive the left movable die 121 and the right movable die 122 to rotate to the initial position W3 respectively.

[0065] In a preferred embodiment, the reset mechanism may include a mounting seat 141 and a tension spring 142.

[0066] Specifically, the mounting seat 141 is arranged on the frame 110 corresponding to the left movable die 121 and the right movable die 122. For example, one mounting seat 141 is arranged on each side of the frame 110 corresponding to the outside of the left movable die 121 and the right movable die 122 respectively. The specific form of the mounting seat 141 may not be limited.

[0067] One end of the tension spring 142 is connected to the left movable mold 121 or the right movable mold 122 on the corresponding side. The other end of the tension spring 142 is connected to the mounting seat 141 on the corresponding side, and is used to provide a driving force for driving the left movable mold 121 and the right movable mold 122 to rotate to the initial position W3.

[0068] In order to adjust the tension of the tension spring 142, that is, to adjust the pulling force of the tension spring 142, the processing device 100 may further include an adjusting mechanism for adjusting the tension of the tension spring 142. The adjusting mechanism may include a telescopic member with one end connected to the tension spring 142. The telescopic member is arranged on the mounting seat 141 and is movable relative to the mounting seat 141 in the left-right direction. Among them, the telescopic member may be a telescopic screw 171 or other telescopic members, which is not limited herein.

[0069] Reference Figure 4 , when the left movable mold 121 and the right movable mold 122 rotate to the initial position W3, they may continue to deflect. In order to prevent the left movable mold 121 and the right movable mold 122 from continuing to deflect, the processing device 100 according to an embodiment of the present invention may further include a limiting mechanism. The limiting mechanism is arranged on the frame body 110 on the corresponding side of the left movable mold 121 and the right movable mold 122, and is used to abut against the left movable mold 121 and the right movable mold 122 when they are in the initial position W3. For example, the limiting mechanism may adopt a limiting rod 150 extending in the front-back direction. When the left movable mold 121 and the right movable mold 122 rotate to the initial position W3, the limiting rod 150 abuts against the left movable mold 121 and the right movable mold 122 on the relatively outward side, so that they stop immediately.

[0070] In order to place the main board workpiece 20 properly before the pressing mold 130 presses down on the main board workpiece, the tops of the left movable mold 121, the right movable mold 122 and the mounting seat 141 may further have a horizontal plane 160 for upwardly supporting the main board workpiece. That is, the tops of the left movable mold 121, the right movable mold 122 and the mounting seat 141 have horizontal planes 160 with the same height, which jointly support the main board workpiece upward. It can be understood that the height of the horizontal plane 160 at the top of the left movable mold 121 and the right movable mold 122 may not be the same as that of the horizontal plane 160 at the top of the mounting seat 141.

[0071] Continued from the above, reference Figure 3 , when the main board workpiece is horizontally placed on the horizontal plane 160 at the tops of the left movable mold 121, the right movable mold 122 and the mounting seat 141, in order to place the position of the main board workpiece in place as soon as possible, the horizontal plane 160 at the top of the mounting seat 141 may further be provided with a positioning block 181 for positioning the placement position of the main board workpiece. The positioning block 181 positions the main board workpiece in two directions, namely the front-back direction and the left-right direction.

[0072] When the main board workpiece placed horizontally on the horizontal plane 160 at the tops of the left movable mold 121, the right movable mold 122 and the mounting base 141 begins to be pressed downward and bent by the pressing mold 130, the connection between the horizontal plane 160 at the tops of the left movable mold 121 and the right movable mold 122 and their respective plane portions 126 can be configured as a smoothly transitioning arc surface, so as to prevent the main board workpiece from being scratched by sharp edges or having creases pressed out when being bent downward.

[0073] In the processing device 100 according to an embodiment of the present invention, one or both of the vertical plates 111 in the frame body 110 may further be provided with a concave notch 112 at a position corresponding to the accommodation space. Through the notch 112, the conditions of the left movable mold 121 and the right movable mold 122 between the two vertical plates 111 can be seen in real time.

[0074] Reference Figure 5 , first, place the main board workpiece to be processed on the horizontal plane 160 at the tops of the left movable mold 121, the right movable mold 122 and the mounting base 141, and determine the position through the positioning block 181. The pressing mold 130 moves downward along the vertical direction, contacts and presses the main board workpiece to be processed. Reference Figure 6 , then the pressing mold 130 continues to press down the main board workpiece and stops when it moves to the target position W1. The left movable mold 121 and the right movable mold 122 synchronously rotate from the initial position W3 to the predetermined position W2 respectively under the pressure of the main board workpiece and the pressing mold 130. At this time, the left movable mold 121, the right movable mold 122 and the pressing mold 130 are all attached and cooperate to clamp the main board workpiece, and the main board workpiece is bent and formed into a motor main board.

[0075] Then the pressing mold 130 moves upward along the vertical direction from the target position W1, and the motor main board wrapped on the pressing mold 130 rises together. Finally, the pressing mold 130 resets, and during the process of disengaging from the left movable mold 121 and the right movable mold 122, the left movable mold 121 and the right movable mold 122 rotate to the initial position W3.

[0076] In summary, according to the processing device 100 of the present utility model, the main board workpiece is processed by pressing the die 130 downward. At the same time, the left movable die 121 and the right movable die 122 rotate. Finally, the left movable die 121, the right movable die 122 and the pressing die 130 jointly form a channel adapted to the bending shape and size of the motor main board, and bend the main board workpiece to form the motor main board, realizing the one-time processing and forming of the motor main board. At the same time, the processing device 100 is also provided with a reset mechanism for driving the left movable die 121 and the right movable die 122 to rotate to the initial position W3, so that the left movable die 121 and the right movable die 122 automatically reset after cooperating with the pressing die 130 to complete the forming of the motor main board, and a limiting mechanism for restricting the left movable die 121 and the right movable die 122 from rotating to the initial position W3 and continuing to deflect is also provided. In addition, a concave notch 112 is provided at the position of the vertical plate 111 in the processing device 100 of the present utility model corresponding to the accommodating space. On the one hand, it can reduce the material consumption and weight of the vertical plate 111. On the other hand, it can observe the processing and forming process in real time and discover problems in time. Finally, through this notch 112, the main board workpiece or the motor main board can be taken out in time in case of an accident.

[0077] Combined with the description and practice of the present utility model disclosed herein, other embodiments of the present utility model will be readily apparent and understandable to those skilled in the art. The description and embodiments are only considered to be exemplary, and the true scope and gist of the present utility model are defined by the claims.
