[0030] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.

[0031] With reference to Figures 1-5 The utility model provides an embodiment: pile shoe making machine, including:

[0032] Processing frame 1, top fixed installation has hydraulic cylinder, and the inner cavity bottom of processing frame 1 is detachably installed with mould 8 for the shaping of pile shoe, and the top of processing frame 1 is provided with through-hole, and the power output end of hydraulic cylinder extends to the inside of processing frame 1 and passes through through-hole.

[0033] The power output end of the hydraulic cylinder is detachably installed with a pressing plate 2 for pile shoe manufacturing, and the mold 8 is located directly below the pressing plate 2. After the fan-shaped steel plate is placed directly above the mold 8, the hydraulic cylinder is started. At this time, the power output end of the hydraulic cylinder moves downward and allows the pressing plate 2 to press the fan-shaped steel plate located directly above the mold 8.

[0034] The deformation groove is opened directly above the mold 8, and the shape of the deformation groove is the same as that of the pressing plate 2. The pressing plate 2 is provided in a conical structure, and the inclined outer wall of the pressing plate 2 is detachably connected with the power output end of the hydraulic cylinder.

[0035] One side of the mold 8 and the inner cavity of the deformation groove are in communication with each other. When the pressing plate 2 moves downward, the bottom thereof is in contact with the arc-shaped edge of the fan-shaped steel plate and provides downward pressure to make the tip of the fan-shaped steel plate rise and be attached to the pressing plate 2. After the fan-shaped steel plate located at the top of the mold 8 is pressed by the pressing plate 2, the large end of the pressing plate 2 is first attached to the outer wall of the fan-shaped steel plate (since the pressing plate 2 is provided in a conical structure, one end of the pressing plate 2 is smaller in size than the other end, the smaller end of the pressing plate 2 is the tip, and the other end is the large end). With the continuous downward movement of the power output end of the hydraulic cylinder, the top of the fan-shaped steel plate is continuously pressed. At this time, the arc-shaped outer wall of the fan-shaped steel plate is deformed and recessed into the inner cavity of the deformation groove. At the same time, the tip of the fan-shaped steel plate rises because it is not subjected to the pressure of the pressing plate 2. When the tip of the fan-shaped steel plate rises, the contact area between the bottom of the fan-shaped steel plate and the inner wall of the deformation groove decreases. With the continuous downward pressure of the pressing plate 2, the fan-shaped steel plate is prone to shift as a whole, so that the tip of the fan-shaped steel plate cannot be on the same horizontal line as the tip of the pressing plate. It is necessary to use a hammer to knock the tip of the fan-shaped steel plate until the tip of the fan-shaped steel plate and the tip of the pressing plate 2 are on the same horizontal line. With the continuous pressure of the pressing plate 2 on the fan-shaped steel plate, the side of the fan-shaped steel plate away from the pressing plate 2 (i.e. the tip of the fan-shaped steel plate) is attached to the tip of the pressing plate 2, and with the downward movement of the pressing plate 2, the tip of the fan-shaped steel plate is finally attached to the tip of the deformation groove. Then, the power output end of the hydraulic cylinder is moved in the opposite direction until the outer wall of the pressing plate 2 is separated from the outer wall of the fan-shaped steel plate. Then, the power output end of the hydraulic cylinder is moved downward again until the outer wall of the pressing plate 2 moves to the inside of the deformation groove and is attached to the outer wall of the fan-shaped steel plate again. Through the upward and downward movement of the power output end of the hydraulic cylinder twice, the repeated extrusion of the pressing plate 2 on the fan-shaped steel plate can be realized, that is, the manufacturing of the pile shoe can be completed, which reduces the scrap rate during the manufacturing of the pile shoe and improves the practicability of the pile shoe manufacturing device.

[0036] In the above manufacturing process, the tip of the fan-shaped steel plate is raised after the pressing plate 2 enters the deformation groove. The tip of the fan-shaped steel plate can be directly observed to determine whether it coincides with the tip of the pressing plate 2. If not, the tip of the fan-shaped steel plate can be adjusted to coincide with the tip of the pressing plate 2 by hitting it with a hammer. However, due to the close distance between the pressing plate 2 and the deformation groove, the contact area between the hammer and the tip of the fan-shaped steel plate is small, making it inconvenient to hit the fan-shaped steel plate. Therefore, in a further embodiment, a top plate 3 is also provided, which is slidingly installed in the inner cavity of the deformation groove. The inner cavity of the deformation groove is provided with a accommodating groove that is adapted to the top plate 3. The bottom of the mold 8 is fixedly installed with a spring telescopic rod 12, which is located directly below the accommodating groove. The top of the spring telescopic rod 12 penetrates the accommodating groove and is fixedly connected to the bottom of the top plate 3. The spring telescopic rod 12 is composed of a top pressing spring, a slide rod and an installation cylinder. The top pressing spring is installed inside the installation cylinder and is attached to one end of the installation cylinder away from the inner wall of the opening end. One end of the slide rod is slidingly installed in the inner cavity of the installation cylinder, and the other end extends to the outside of the installation cylinder. The end of the slide rod inside the installation cylinder is fixedly connected to the other end of the top pressing spring. The end of the slide rod away from the installation cylinder is fixedly connected to the outer wall of the top plate 3. When the top of the top plate 3 is subjected to a downward force, the slide rod slides along its own axis direction into the installation cylinder. At this time, the top pressing spring is compressed. When the force on the top of the top plate 3 disappears, the top pressing spring quickly rebounds and resets the top plate 3 (for the specific installation method between the slide rod, the top pressing spring and the installation cylinder, please refer to Figure 4 ).

[0037] The top of the spring telescopic rod 12 penetrates the accommodating groove and extends into the inside of the mold 8. At this time, the fan-shaped steel plate is placed directly above the top plate 3. Under the action of the top plate 3, the fan-shaped steel plate is located directly above the mold 8. When the hydraulic cylinder is started, the pressing plate 2 moves downward and is attached to the top of the fan-shaped steel plate. As the power output end of the hydraulic cylinder moves downward, the top of the slide rod is subjected to a downward force. When the fan-shaped steel plate moves into the inner cavity of the deformation groove, the power output end of the hydraulic cylinder moves upward. The force on the top of the slide rod disappears and moves upward, so that the top of the fan-shaped steel plate is always attached to the outer wall of the pressing plate 2. When the pressing plate 2 moves upward, the fan-shaped steel plate is prevented from moving away from the pressing plate 2 due to inertia. The position of the fan-shaped steel plate does not change when the pressing plate 2 is pressed each time.

[0038] When the sector steel plate is placed on the top of the top plate 3, when the bottom of the pressing plate 2 is attached to the top of the sector steel plate and presses the top of the sector steel plate, (because the sector steel plate is finally formed into a conical structure after being extruded by the pressing plate 2, so the bottom of the pressing plate 2 is bent and inclined, resulting in that the contact area between the pressing plate 2 and the top of the sector steel plate is small when they are attached, and at the same time the pressing plate 2 pushes the sector steel plate into the inside of the deformation groove to make it form, the tip of the sector steel plate is constantly raised until it is completely attached to the outer wall of the pressing plate 2, and in this process, because the contact area between the pressing plate 2 and the sector steel plate increases from small to large, the tip of the sector steel plate is prone to deviation when it is raised), the staff beside needs to hold a knocking tool to knock the tip of the sector steel plate and constantly adjust the position of the sector steel plate to prevent the tip of the sector steel plate from deviating from the tip of the pressing plate 2.

[0039] Because the top plate 3 supports the sector steel plate, the distance between the tip of the sector steel plate and the top of the mold 8 increases when the tip of the sector steel plate is raised, so it is beneficial to observe the position of the tip of the sector steel plate and the tip of the pressing plate 2, and it can also increase the contact area between the hammer and the tip of the sector steel plate, so that the tip of the sector steel plate can be knocked by the hammer, thereby achieving the purpose of adjusting the position of the tip of the sector steel plate.

[0040] The top of the top plate 3 is provided with a groove matched with the sector steel plate after being extruded, and the shape of the groove is the same as the shape of the bottom of the pressing plate 2. When the sector steel plate moves down to the bottom and is attached to the bottom of the inner cavity of the mold 8, the top of the top plate 3 enters the accommodation groove and is flush with the bottom of the inner cavity of the mold 8. At this time, as the pressing plate 2 continuously presses the sector steel plate, the bottom of the sector steel plate deforms and is completely attached to the inner wall of the groove, so that the sector steel plate can be pressed. When the sector steel plate moves up with the pressing plate 2, the outer wall of the sector steel plate is always attached to the inner wall of the groove to prevent it from shaking and deviating when moving up, thereby increasing the stability of the sector steel plate when moving up, and avoiding the deviation between the sector steel plate and the outer wall of the pressing plate 2 when the pressing plate 2 presses the sector steel plate again, which causes the sector steel plate to be extruded and not match the predetermined shape.

[0041] The fixing member is arranged outside the mold 8, and the mold 8 and the processing frame 1 can be disassembled through the fixing member. The mold 8 can be quickly replaced, and different sizes of molds 8 and pressing plates 2 are needed to press different sizes of sector steel plates when making different sizes of shoes. The existing mold 8 is connected to the inner wall of the processing frame 1 by bolts. When the mold 8 is replaced, the nut needs to be fixed and the bolt needs to be rotated at the same time, so that the bolt and the nut can be separated, which increases the degree of complexity when the mold 8 is replaced, and the time and effort required.

[0042] The fixing piece comprises a fixing block 11 and a moving slide rail 9, one side of the moving slide rail 9 is fixedly connected with the bottom of the inner cavity of the machining frame 1, and two fixing blocks 11 are slidingly installed in the inner cavity of the moving slide rail 9, the two fixing blocks 11 can move left and right along the moving slide rail 9, and the moving tracks of the two fixing blocks 11 are limited, so that the stability of the back-and-forth movement of the two fixing blocks 11 is improved.

[0043] The support block 4 is symmetrically and fixedly installed on both sides of the mold 8, the bottom of the support block 4 is fixedly installed with a positioning column 5, and the top of the fixing block 11 is provided with a positioning hole matched with the positioning column 5, when the mold 8 is installed in the inner part of the machining frame 1, the distance between the two fixing blocks 11 is adjusted according to the size of the mold 8, then the mold 8 is placed between the two fixing blocks 11, until the two positioning columns 5 are inserted into the two positioning holes at the same time, until the bottom of the support block 4 and the top of the fixing block 11 are attached, at this time, the adjacent side of the two fixing blocks 11 and the two sides of the fixing block 11 are attached, so that the preliminary positioning of the mold 8 can be realized.

[0044] The inner cavity of the moving slide rail 9 is rotatably installed with a bidirectional screw rod 10, and the outer wall of the two fixing blocks 11 is provided with a threaded hole matched with the bidirectional screw rod 10, the two fixing blocks 11 are sleeved on the outer wall of the bidirectional screw rod 10 through the threaded holes, the distance between the two fixing blocks 11 can be accurately adjusted through rotating the bidirectional screw rod 10 under the cooperation of the threaded holes, and the fixed blocks 11 after moving are positioned, so that the two sides of the mold 8 are clamped, the mold 8 placed between the two fixing blocks 11 is fixed, and the distance between the two fixing blocks 11 is adjusted by rotating the bidirectional screw rod 10, so that the mold 8 of different sizes is fixed.

[0045] When the mold 8 needs to be replaced, the fixing block 11 is separated from the outer wall of the mold 8 by rotating the bidirectional screw rod 10, and then the mold 8 is taken out from between the two fixing blocks 11.

[0046] The power output end of the hydraulic cylinder is fixedly connected with a connecting block 6, the top of the pressing plate 2 is symmetrically provided with a vertical plate 7, the two sides of the connecting block 6 and the side of the two vertical plates 7 away from each other are fixedly provided with a connecting lug plate 13, the top of the connecting lug plate 13 is provided with a through hole, and the inner cavity of the through hole is movably provided with a limiting bolt; when the pressing plate 2 is placed directly below the connecting block 6, the two vertical plates 7 are located at the two sides of the connecting block 6, at the moment, the connecting lug plate 13 installed on the outer wall of the two vertical plates 7 is located directly below the connecting lug plate 13 at the two sides of the connecting block 6, then the small head end of the limiting bolt is inserted into the other through hole through one of the through holes, then the nut is installed on the small head end of the limiting bolt and the bolt is continuously rotated, until one end of the nut and the bottom of one of the connecting lug plates are tightly attached, and the large head end of the limiting bolt and the top of the other connecting lug plate 13 are attached, the connection between the pressing plate 2 and the connecting block 6 is realized under the extrusion of the limiting bolt and the nut, thereby facilitating the disassembly and assembly of the pressing plate 2 and the power output end of the hydraulic cylinder, and the replacement of the pressing plate 2 of different sizes.
