Description

Technical Field

[0001] The utility model belongs to the technical field of flexible pad preparation, and in particular relates to a preparation device for a flexible pad. Background Art

[0002] The electric shovel is a special mining and loading equipment for large open-pit mines, which can be used for stripping and mining and loading operations in large open-pit mines with a capacity of more than 10 million tons. It adopts 6000V electric drive and can be used with 80-220 ton dump trucks or 100 ton railway dump trucks. It is a key mining equipment for open-pit mines.

[0003] The bucket bolt will be worn out when the electric shovel is continuously opening the bucket during operation. When the bucket bolt is worn, the vertical fixer pad needs to be adjusted to achieve normal bottom opening. Normally, an electric shovel loads 100-120 vehicles every eight hours, and each vehicle needs to load and unload 5-6 buckets of materials, that is, the electric shovel needs to open the bucket 500-600 times per shift for normal operation; when the bucket bolt is worn beyond the limit and the bottom opening cannot be achieved normally, the fixer pad must be adjusted in time to ensure that the depth of the bucket bolt meets the bottom opening requirements. If the fixer pad is not adjusted in time, the fixer will generate strong impact vibration during the bottom opening process due to the lack of pad, which will cause damage to the fixer.

[0004] The replacement of the currently used one takes a long time, which affects the work efficiency. In addition, the existing fixer pad is made of steel, which has high hardness and strong rigidity, but is also brittle and easy to be damaged, and cannot be used stably for a long time.

[0007] Wherein, the cutting die comprises: a bottom plate and a surrounding plate protruding along the edge of the bottom plate; the surrounding plate is distributed along the edge of the bottom plate, and the bottom plate and the surrounding plate are vertically connected to form the cavity.

[0008] Furthermore, the cutting die also includes a pressing plate matched with the bottom plate, the pressing plate is fixed in the cavity, and the pressing plate abuts against the bottom plate.

[0009] Furthermore, one side of the cutting die is recessed to form an arc-shaped notch.

[0010] Furthermore, the bottom plate includes a horizontal portion and a vertical portion connected vertically; the horizontal portion is symmetrical about the midline of the vertical portion, the arc-shaped notch is located in the horizontal portion, and the midline of the vertical portion is colinear with one of the diameters of the arc-shaped notch.

[0011] Furthermore, a plurality of windows are provided on the surface of the pressure plate, and the windows are spaced apart along the extension direction of the horizontal portion or the extension direction of the surface of the vertical portion.

[0012] Beneficial effects: The utility model presses the cutter die through the movement of the die-casting device in the fixed frame to complete the punching of the elastic pad, thereby quickly producing a fixer pad matching the cutter die. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] In order to make the purpose, technical solution and advantages of the present application clearer, the present invention will be described in further detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0017] Figure 1 The invention discloses a device for preparing a flexible pad according to an embodiment of the utility model.

[0018] Reference Figure 1According to an embodiment of the utility model, a preparation device for a flexible pad includes: a fixing frame 1, a cutting die 2 and a die-casting device 3. Among them, the fixing frame 1 serves as the basic structure of the entire device, and its main function is to fix and support other components. A convex side inside the fixing frame 1 forms a mounting table 11 for fixing the fixing part of the die-casting device 3. The cutting die 2 is a mold for forming a flexible pad, and a cavity 4 is provided therein, that is, the part of the mold used to form the shape of the flexible pad. The cutting die 2 is placed between the die-casting device 3 and the elastic pad, and is used to die-cast the material 3 during the die-casting process.

[0019] Continue to refer to Figure 1 Specifically, the die casting device 3 includes: a jack 31, a booster pump 32 and a base 33. The jack 31 is a mechanical device for applying pressure, with a fixed end fixed on the mounting table 11 of the fixed frame 1, and a movable end connected to the base 33, for transmitting pressure to the die 2, thereby molding the elastic pad material. The booster pump 32 is connected to the jack 31 to provide a power source for the jack 31, so that it can move in the fixed frame 1, thereby achieving compression and molding of the material. The base 33 is used to fix the structure of the movable end of the jack 31 to ensure that the jack 31 can apply pressure stably.

[0020] Furthermore, the working process of the whole device is as follows: First, the user places the elastic pad material under the cavity 4 of the cutter die 2. Then, the construction personnel provide power to the jack 31 through the booster pump 32, so that the movable end of the jack 31 drops and applies pressure to the material. Under the action of pressure, the elastic pad material is formed in the cavity 4 of the cutter die 2 to form the required shape and size. Finally, the pressure is released, and the molded elastic pad is taken out to complete the whole preparation process. Among them, the elastic pad can be made of waste coal conveyor belts, rubber, rubber and other elastic materials. The rubber retainer pad thus obtained can buffer the vibration impact of opening the bottom scoop door and reduce the damage caused by the rigid connection between the retainer and the retainer pad. In addition, the retainer pad made of materials such as rubber or rubber is more durable and improves the dispatch rate of most electric shovel equipment.

[0021] Figure 2 It is a schematic structural diagram of a knife die according to an embodiment of the utility model.

[0022] Reference Figure 2Specifically, the cutting die 2 includes: a bottom plate 21 and a surrounding plate 22. The bottom plate 21 is in the shape of a thin plate, and the edges of the bottom plate 21 are distributed around, and the bottom plate 21 and the surrounding plate 22 are vertically connected to form a cavity 4. The bottom plate 21 includes a horizontal portion 211 and a vertical portion 212 that are perpendicular to each other, and the horizontal portion 211 and the vertical portion 212 are symmetrical about the center line of the vertical portion 212. In order to match the die-cast elastic pad with the fastener pad required at the construction site, in this embodiment, one side of the base 33 is recessed to form an arc-shaped notch 5. When producing the fastener pad, the arc-shaped notch 5 divides one side of the elastic pad in the cavity 4 into two parts, thereby facilitating the installation of the generated fastener pad.

[0023] Preferably, in order to facilitate the quick determination of the front and back sides of the produced fixture pad, thereby facilitating the use of construction personnel, in this embodiment, the die cutter 2 also includes a pressing plate 23. The pressing plate 23 matches the shape of the bottom plate 21, and the pressing plate 23 and the bottom plate 21 are parallel to each other. A plurality of windows 231 are provided on the surface of the pressing plate 23, and each window 231 is arranged along the extension direction of the horizontal portion 211 or the vertical portion 212. During use, the pressing plate 23 abuts against the surface of the bottom plate 21, and a protrusion matching the window 231 is formed on one side of the fixture pad generated after the die-casting device 3 is pressed down, so that the front and back sides of the produced fixture pad can be quickly distinguished.

[0024] In summary, the utility model presses the cutter die through the movement of the die-casting device in the fixing frame to complete the punching of the elastic pad, thereby quickly producing the holder pad matching the cutter die.
