Description

Technical Field

[0001] This invention relates to the field of gantry milling machine technology, and in particular to an energy-saving and environmentally friendly gantry milling machine for automotive mold processing. Background Technology

[0002] A gantry milling machine is a large, heavy-duty CNC machine tool. Its most prominent feature is a robust, "gate" or "bridge"-like frame structure (i.e., a gantry frame). In this frame, the spindle head, which houses the spindle tool, can move laterally along the crossbeam, while the crossbeam itself can move longitudinally along the vertical guide rails on both sides. The workpiece is fixed on a huge worktable. This structure provides extremely high rigidity and stability, making it particularly suitable for high-precision milling, drilling, and boring of large, heavy workpieces (such as machine tool beds, wind power equipment components, and automotive molds).

[0003] When machining automotive molds, the shapes within these molds are not flat, resulting in grooves of varying sizes and depths (e.g., in car door handles). During milling on a gantry milling machine, metal shavings generated by the cutting tool accumulate inside these grooves. This accumulation not only affects machining accuracy but can also accelerate tool wear and even cause equipment malfunctions. For example, patent application CN202320719871.3 discloses a gantry milling machine for convenient workpiece fixing. This application also confirms that a large amount of metal shavings are generated during milling on a gantry milling machine. However, due to the presence of the cutting tool, even suction methods cannot effectively remove the accumulated metal shavings from the grooves.

[0004] Therefore, how to provide an energy-saving and environmentally friendly gantry milling machine for automotive mold processing is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] The purpose of this invention is to provide an energy-saving and environmentally friendly gantry milling machine for automotive mold processing, so as to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an energy-saving and environmentally friendly gantry milling machine for automotive mold processing, comprising a gantry milling machine body, a displacement mechanism disposed on the front of the gantry milling machine body, a drive tool mechanism disposed on the front of the displacement mechanism, a tool disposed at the bottom of the drive tool mechanism, and a processing base disposed on the front side of the top of the gantry milling machine body, and further comprising:

The hydraulic lifting rod has a telescopic end, and a lifting plate is provided at the telescopic end of the hydraulic lifting rod. A connecting frame is provided at the bottom of the lifting plate. When the hydraulic lifting rod is working, it can drive the lifting plate and the connecting frame to move synchronously.

[0008] Connecting frame 2 is located below connecting frame 1 and is on the same axis as connecting frame 1. A rotating connecting seat 2 and a telescopic sleeve that can be extended and retracted are provided in the middle of connecting frame 2. The rotating connecting seat 1 is provided at the other end of the telescopic sleeve. Connecting frame 2 is connected to connecting frame 1 through rotating connecting seat 2, telescopic sleeve and rotating connecting seat 1. When connecting frame 1 rises or falls, the movement of connecting frame 2 can be controlled.

[0009] A positioning rotating frame is located outside the drive knife mechanism. A flipping connecting block is located in the middle of the positioning rotating frame. The flipping connecting block is connected to the connecting frame 2. The flipping connecting block can rotate inside the positioning rotating frame. A rotating baffle is located on the side of the flipping connecting block away from the drive knife mechanism. An industrial fan is located inside the rotating baffle. A toggle frame is located on the front of the positioning rotating frame. The rotating baffle and the industrial fan can rotate on one side of the flipping connecting block.

[0010] The extrusion roller is located outside the drive knife mechanism. When the rotating baffle rotates with the flipping connecting block, the rear end of the rotating baffle near the drive knife mechanism contacts the extrusion roller and is extruded by the extrusion roller.

[0011] Furthermore, it also includes a drive assembly, which consists of a fixed plate, a hydraulic lifting rod, a lifting plate, and a connecting frame.

[0012] The fixed plate is fixedly connected to the outside of the drive knife mechanism near the top. The hydraulic lifting rod is fixedly connected to the top of the fixed plate. The lifting plate is fixedly connected to the output shaft of the fixed plate. The connecting frame is fixedly connected to the bottom rear side of the lifting plate. When working, the hydraulic lifting rod can drive the lifting plate and the connecting frame to move up and down.

[0013] Furthermore, it also includes an angle adjustment assembly, which consists of a rotating connecting seat one, a telescopic sleeve, a rotating connecting seat two, a connecting frame two, a flipping connecting block, and a positioning rotating frame;

[0014] The first rotating connecting seat is rotatably connected to the inner side of the first connecting frame. The telescopic sleeve is fixedly connected to the bottom of the first rotating connecting seat. The second rotating connecting seat is fixedly connected to the bottom of the telescopic sleeve. The second connecting frame is rotatably connected to the middle of the second rotating connecting seat. The flipping connecting block is fixedly connected to the side of the second connecting frame away from the driving knife mechanism. The positioning rotating frame is fixedly connected to the outer side of the driving knife mechanism. The first rotating connecting seat can rotate within the first connecting frame. The telescopic sleeve can extend and retract synchronously. The second rotating connecting seat can rotate within the second connecting frame.

[0015] Furthermore, it also includes a chip removal assembly, which consists of a rotating shaft, a rotating baffle, an industrial fan, a bow spring, a protective shell, an extension frame, a pressing roller, and a toggle frame;

[0016] The rotating shaft is rotatably connected to the middle of the side of the flipping connecting block away from the second connecting frame. The rotating baffle is fixedly connected to the other end of the rotating shaft. The industrial fan is located inside the rotating baffle and is located away from the driving knife mechanism. The bow-shaped spring is fixedly connected to the side of the flipping connecting block away from the second connecting frame and is located in front of and behind the rotating shaft. The protective shell is fixedly connected to the side of the rotating baffle close to the flipping connecting block. The extension frame is fixedly connected to the left and right sides of the driving knife mechanism near the bottom. The extrusion roller is rotatably connected to the side of the extension frame away from the driving knife mechanism. The actuating frame is fixedly connected to the bottom left side of the positioning rotating frame. The rotating baffle rotates on the side of the flipping connecting block via the rotating shaft.

[0017] Furthermore, the end of the bow-shaped spring away from the flipping connecting block is fixedly connected to the rotating baffle, and the bow-shaped spring can move the rotating baffle and then reset it.

[0018] Furthermore, both the rotating shaft and the bow-shaped spring are housed inside the protective shell, which protects the rotating shaft and the bow-shaped spring.

[0019] Furthermore, a compression extension plate is fixedly connected to the left side of the back of the actuating frame. When the flipping connecting block drives the rotating baffle to rotate inside the positioning rotating frame, the rotating baffle can contact the compression extension plate.

[0020] Furthermore, the hydraulic lifting rod, connecting frame one, rotating connecting seat one, telescopic sleeve, rotating connecting seat two, connecting frame two, flipping connecting block, positioning rotating frame, rotating shaft, rotating baffle, industrial fan, bow spring, protective shell, extension frame, extrusion roller and actuating frame are all in pairs and symmetrically distributed on the left and right sides of the drive knife mechanism, enabling the rotating baffle and flipping connecting block on both sides of the drive knife mechanism to rotate simultaneously.

[0021] The beneficial effects of this invention are:

[0022] 1. This invention forms an air curtain at the bottom of the drive tool mechanism using an industrial fan, which can confine the oil mist generated by the evaporation of coolant during processing to a local area, reduce the spread of oil mist, and improve the working environment. At the same time, the air curtain acts as a barrier to prevent external dust from entering the processing area, ensuring processing accuracy and workpiece quality.

[0023] 2. According to the different groove depths, the angles of the rotating baffle and the industrial fan are controlled by the hydraulic lifting rod: for shallow grooves, the industrial fan blows air at a smaller angle to directly blow out the metal waste accumulated on the surface; for deep grooves, the rotating baffle increases the rotation amplitude, so that the air force of the industrial fan penetrates deep into the bottom of the groove to thoroughly remove the accumulated metal waste. This avoids the waste from interfering with the processing, reduces downtime for cleaning, and improves processing continuity and workpiece surface quality.

[0024] 3. In this invention, the industrial fan continuously blows air onto the cutting tool while removing debris, which helps reduce the heat generated by the cutting tool when it rotates at high speed and prevents overheating damage. In addition, the air can blow away the fine metal debris adhering to the cutting tool, reduce tool wear, thereby extending the tool's service life and reducing replacement costs.

[0025] 4. In this invention, when the rotating baffle is covered with metal shavings mixed with coolant, the rotating baffle is squeezed and twisted as it passes the actuating frame by the lowering operation of the lifting plate. Then, it is reset under the action of the bow spring, generating a swinging action, which automatically removes the attached debris, keeps the rotating baffle and industrial fan clean, avoids the accumulation of debris from affecting performance, and reduces the frequency of manual cleaning and maintenance.

[0044] Example 3

[0045] refer to Figure 7-9 Based on Embodiment 2, the present invention provides a technical solution: it also includes a chip removal assembly 8, which is composed of a rotating shaft 801, a rotating baffle 802, an industrial fan 803, a bow spring 804, a protective shell 805, an extension frame 806, a pressing roller 807, and a toggle frame 808.

[0046] The rotating shaft 801 is rotatably connected to the middle of the side of the flipping connecting block 705 away from the second connecting frame 704. The rotating baffle 802 is fixedly connected to the other end of the rotating shaft 801.

[0048] The rotating shaft 801 and the bow spring 804 are both located inside the protective shell 805, which can protect the rotating shaft 801 and the bow spring 804.

[0049] A compression extension plate is fixedly connected to the left side of the back of the actuating frame 808. When the flipping connecting block 705 drives the rotating baffle 802 to rotate inside the positioning rotating frame 706, the rotating baffle 802 can contact the compression extension plate.

[0050] The hydraulic lifting rod 602, connecting frame one 604, rotating connecting seat one 701, telescopic sleeve 702, rotating connecting seat two 703, connecting frame two 704, flipping connecting block 705, positioning rotating frame 706, rotating shaft 801, rotating baffle 802, industrial fan 803, bow spring 804, protective shell 805, extension frame 806, extrusion roller 807, and actuating frame 808 are all in pairs and symmetrically distributed on the left and right sides of the drive knife mechanism 3, enabling the rotating baffle 802 and flipping connecting block 705 on both sides of the drive knife mechanism 3 to rotate simultaneously.

[0051] Also includes:

[0052] The hydraulic lifting rod 602 is located outside the drive knife mechanism 3. The hydraulic lifting rod 602 has a telescopic end. The telescopic end of the hydraulic lifting rod 602 is provided with a lifting plate 603. The bottom of the lifting plate 603 is provided with a connecting frame 604. When the hydraulic lifting rod 602 is working, it can drive the lifting plate 603 and the connecting frame 604 to move synchronously.

[0053] Connecting frame 2 704 is located below connecting frame 1 604 and is on the same axis as connecting frame 1 604. A rotating connecting seat 2 703 and a telescopic sleeve 702 are provided in the middle of connecting frame 2 704. A rotating connecting seat 1 701 is provided at the other end of telescopic sleeve 702. Connecting frame 2 704 is connected to connecting frame 1 604 through rotating connecting seat 2 703, telescopic sleeve 702 and rotating connecting seat 1 701. When connecting frame 1 604 rises or falls, connecting frame 2 704 can be controlled to move.

[0054] A positioning rotating frame 706 is located outside the driving knife mechanism 3. A flipping connecting block 705 is provided in the middle of the positioning rotating frame 706. The flipping connecting block 705 is connected to the connecting frame 704. The flipping connecting block 705 can rotate inside the positioning rotating frame 706. A rotating baffle 802 is provided on the side of the flipping connecting block 705 away from the driving knife mechanism 3. An industrial fan 803 is provided inside the rotating baffle 802. A toggle frame 808 is provided on the front of the positioning rotating frame 706. The rotating baffle 802 and the industrial fan 803 can rotate on the side of the flipping connecting block 705.

[0055] The extrusion roller 807 is located outside the drive knife mechanism 3. When the rotating baffle 802 rotates with the flipping connecting block 705, the rear end of the rotating baffle 802 near the drive knife mechanism 3 contacts the extrusion roller 807 and is extruded by the extrusion roller 807.

[0056] When processing automotive molds, the workpiece is placed on top of the processing base 5 and clamped. Then, the displacement mechanism 2 is controlled to move left and right to the upper side of the workpiece. At the same time, the drive tool mechanism 3 and the tool 4 are controlled to rise and fall. When the drive tool mechanism 3 and the tool 4 fall, the tool 4 contacts the workpiece. With the help of external coolant spraying onto the tool 4, the workpiece can be processed. Grooves are generated when the tool 4 is processing. At the same time, when the coolant comes into contact with the high-speed rotating tool 4, the heat on the tool 4 can be evaporated, and some oil mist will rise. By controlling the industrial fan 803 to work, an air curtain can be formed on the left and right sides of the bottom of the drive tool mechanism 3, which can effectively suppress the coolant oil mist during evaporation. At the same time, the presence of the air curtain can prevent dust in the air from entering the processing area.

[0057] When the cutting tool 4 processes the groove in the workpiece, it generates a large amount of metal waste. The accumulation of metal waste varies depending on the depth of the groove. When the groove is relatively shallow, the hydraulic lifting rod 602 is activated, causing it to lift the lifting plate 603. As the lifting plate 603 rises, the connecting frame 604 at the bottom drives the rotating connecting seat 701 to rise, causing the rotating connecting seat 701 to rotate within the connecting frame 604. Simultaneously, the telescopic sleeve 702 extends, causing the rotating connecting seat 703 on the other side of the telescopic sleeve 702 to rotate within the connecting frame 704. At this time, the force on the connecting frame 704 enables the flipping connecting block 705 to rotate in the positioning rotating frame 706 outside the driving knife mechanism 3, so that the rotating baffle 802 on the other side of the flipping connecting block 705 can rotate downward synchronously in the positioning rotating frame 706, and the industrial fan 803 faces the side of the tool 4. At this time, by controlling the rising height of the lifting plate 603, the rotation angle of the rotating baffle 802 is increased. During the rotation of the rotating baffle 802, the rotating baffle 802 contacts the extrusion roller 807 outside the driving knife mechanism 3, so that the extrusion roller 807 presses against the rotating baffle. The outer rear of 802 is pressed, causing the rotating shaft 801 on the rotating baffle 802 to rotate outside the flipping connecting block 705. At the same time, the bow spring 804 twists, allowing the industrial fan 803 on the rotating baffle 802 to rotate synchronously with the increase of the rotation angle of the rotating baffle 802. For shallow grooves, the rotating baffle 802 can be controlled to rotate until it is only slightly in contact with the pressing roller 807. At this time, the industrial fans 803 on both sides of the drive knife mechanism 3 can deliver air to the groove and the knife 4 in the groove, which can ventilate the shallow groove. The accumulated metal scrap inside is blown out directly, which can cool down the tool 4 and remove the metal scrap adhering to the tool 4. For deeper grooves, the rotation amplitude of the control baffle 802 is increased. At this time, the control baffle 802 and the extrusion roller 807 are in contact with the maximum stroke, which can make the industrial fan 803 on the control baffle 802 rotate to the maximum amplitude. In this way, the air force delivered by the industrial fan 803 can penetrate deeper into the groove, thereby blowing up and removing the metal scrap accumulated at the bottom of the deeper groove, while effectively cooling the tool 4 at the bottom of the groove.

[0058] When the industrial fan 803 removes the metal shavings generated during the machining of the tool 4, the operation of the tool 4 causes the metal shavings mixed with coolant to adhere to the rotating baffle 802. Controlling the lifting plate 603 to descend allows the connecting frame 604 to be squeezed by the rotating connecting seat 701, the telescopic sleeve 702, and the rotating connecting seat 703. This causes the connecting frame 704 and the flipping connecting block 705 to rotate upward within the positioning rotating frame 706, allowing the rotating baffle 802 to rotate upward synchronously outside the drive tool mechanism 3. When the rotating baffle 802 passes the actuating frame 808, it contacts the extrusion extension plate and twists under the action of the extrusion extension plate. When the rotating baffle 802 separates from the extrusion extension plate, the bow spring 804 elastically recovers, allowing the rotating baffle 802 to reset outside the flipping connecting block 705 via the rotating shaft 801. During the reset process, the metal shavings adhering to the rotating baffle 802 are removed, giving the device a self-cleaning function.

[0059] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
