Detailed implementation manners

[0036] To make the objectives, technical solutions, and advantages of the embodiments of the present disclosure clearer, the following will clearly and completely describe the technical solutions of the embodiments of the present disclosure with reference to the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present disclosure without creative efforts shall fall within the scope of protection of the present disclosure.

[0037] Please refer to Figures 1-9 , a diamond saw blade cold pressing processing device provided by an embodiment of the present invention includes a frame 1, and further includes a die base 2, which is installed in the frame 1, and a retaining ring 201 is movably installed on the top of the die base 2. A die cavity 202 is formed between the die base 2 and the retaining ring 201. A cold pressing head 3 is installed with a telescopic cylinder 304 between it and the frame 1. A guide plate 4 is movably installed in the frame 1. The guide plate 4 is lapped on the top of the cold pressing head 3. A protective sleeve 401 and an elastic cushion plate 402 are installed at the bottom of the guide plate 4. The cold pressing head 3 is located inside the protective sleeve 401. An offset determination assembly 5 is elastically installed on the outside of the protective sleeve 401, and its top is inclined and abutted against the side wall of the cold pressing head 3. An annular docking groove 403 matching the bottom end of the offset determination assembly 5 is formed in the elastic cushion plate 402. A plurality of clamping jaws 6 that abut against the offset determination assembly 5 are movably embedded in the protective sleeve 401. When the cold pressing head 3 descends to push open the offset determination assembly 5, the raw materials in the die cavity 202 are pressed. When the cold pressing head 3 ascends, the clamping jaws 6 are used to clamp the formed blank by the reset of the offset determination assembly 5.

[0038] Specifically, a die holder 2 is installed at the center of the frame 1. The die holder 2 is firmly fixed to the frame 1 by bolts or other fastening means. A retaining ring 201 is movably installed in the die holder 2. A die cavity 202 for placing the raw material of the diamond saw blade is formed by the cooperation between the retaining ring 201 and the die holder 2. The piston rod 801 of the telescopic cylinder 304 is vertically connected to the cold pressing head 3 downward. The bottom of the cold pressing head 3 is a plane matching the shape of the die cavity 202 to ensure uniform force during the pressing process. Above the cold pressing head 3, a guide plate 4 is installed inside the frame 1. The guide plate 4 is slidably connected to the frame 1 to ensure that the cold pressing head 3 can maintain verticality and stability when moving up and down. A protective sleeve 401 is installed at the center position of the bottom of the guide plate 4. The internal space of the protective sleeve 401 allows the cold pressing head 3 to move independently to prevent damage to the cold pressing head 3 caused by lateral offset during the pressing process. An annular docking groove 403 is formed in the elastic cushion plate 402 for cooperating with the offset determination component 5. The top of the offset determination component 5 is inclined to form an inclined contact surface against the bottom of the cold pressing head 3. When the cold pressing head 3 descends, it can push the offset determination component 5 to insert outward into the annular docking groove 403 to pre-check the flatness of the cold pressing head 3. Inside the protective sleeve 401, a plurality of clamping jaws 6 are installed at equal intervals around the edge of the cold pressing head 3. The clamping jaws 6 can maintain the freedom of movement in the horizontal direction. During the pressing process, each clamping jaw 6 is pushed open by the cold pressing head 3. After the cold pressing head 3 moves up to a suitable height, the retaining ring 201 descends to expose the edge of the formed blank. The clamping jaws 6 are then squeezed by the elastic force of the offset determination component 5, and then the saw blade blank is clamped by the cooperation of multiple clamping jaws 6, without the need for an additional ejection mechanism or staff to take it out, making the cold pressing forming more efficient.

[0039] Compared with the prior art, in the embodiment of the present invention, the cold pressing head 3 drives the lifting of the guide plate 4 placed above it. Before the cold pressing head 3 presses the raw material in the die cavity 202, the elastic cushion plate 402 first contacts the die holder 2, and then the cold pressing head 3 descends independently inside the protective sleeve 401. After successfully pushing open the offset determination component 5 and inserting it into the elastic cushion plate 402, the formal pressing starts, avoiding uneven pressing quality caused by the direct pressing of the cold pressing head 3. At the same time, when the cold pressing head 3 rises, by using the reset function of the offset determination component 5, the clamping jaws 6 are driven to clamp the formed blank, realizing the automatic grasping and taking out of the blank, which not only avoids damage or deformation of the blank but also simplifies the operation process.

[0040] In a further embodiment of the present invention, a plurality of positioning insertion rods 404 and top springs 405 are installed between the elastic cushion plate 402 and the guide plate 4. The positioning insertion rods 404 are located inside the top springs 405. Arc-shaped retaining strips are fixedly connected to both sides of the bottom of the elastic cushion plate 402. Positioning grooves for the arc-shaped retaining strips to enter are formed on the top surface of the die base 2. Specifically, a plurality of corresponding insertion holes 203 are preset on the guide plate 4 for the installation position of the elastic cushion plate 402. The top of the positioning insertion rod 404 passes through these insertion holes 203, and its bottom is fixed on the elastic cushion plate 402. A top spring 405 is sleeved around each positioning insertion rod 404. One end of the top spring 405 abuts against the guide plate 4, and the other end abuts against the top surface of the elastic cushion plate 402. Such a design enables the elastic cushion plate 402 to effectively buffer through the elastic deformation of the top spring 405 when receiving the pressure transmitted by the cold pressing head 3, reducing the damage to the device itself caused by the impact, and at the same time improving the smoothness of the pressing process. In addition, in order to ensure that the elastic cushion plate 402 can be accurately positioned and remain stable during the pressing process, arc-shaped retaining strips are respectively fixedly connected to both sides of the bottom of the elastic cushion plate 402. The design of these arc-shaped retaining strips not only increases the contact area between the elastic cushion plate 402 and the die base 2, improving the stability of the connection, but also plays a final guiding role when the cold pressing head 3 presses down.

[0041] In a further embodiment of the present invention, a retaining ring 406 is fixedly connected to the bottom of the inner wall of the protective sleeve 401. The top of the protective sleeve 401 is fixed to the bottom of the guide plate 4 by bolts. An annular protrusion 301 is provided on the outer wall of the cold pressing head 3, and the outer wall of the annular protrusion 301 is in contact with the inner wall of the protective sleeve 401. Specifically, the presence of the retaining ring 406 can provide a clear limit for the descent of the cold pressing head 3, ensuring that it stops at a predetermined position and preventing the cold pressing head 3 from completely exposing from the protective sleeve 401.

[0042] In a further embodiment of the present invention, the offset determination assembly 5 includes a plurality of connecting frames 501 fixedly installed on the outer wall of the protective sleeve 401. A Z-shaped plug-in frame 502 is installed inside the connecting frame 501. A through groove 503 is vertically opened inside the Z-shaped plug-in frame 502. A sliding rod 504 is installed inside the through groove 503. A connecting spring 505 is installed between the bottom of the sliding rod 504 and the bottom inner wall of the through groove 503. Pressure springs 506 are installed between both ends of the sliding rod 504 and the inner wall of the connecting frame 501. Specifically, the sliding rod 504 is a key component in the offset determination assembly 5. It can slide freely inside the through groove 503. The connecting spring 505 installed between the bottom of the sliding rod 504 and the bottom inner wall of the through groove 503 provides an upward elastic force for the sliding rod 504, enabling it to maintain a preset initial height when there is no external force. At the same time, the pressure springs 506 are located on both sides of the sliding rod 504 and are symmetrically distributed. When the top of the Z-shaped plug-in frame 502 is squeezed by the cold pressing head 3, the pressure springs 506 can provide additional support and buffering, and after the cold pressing head 3 leaves the Z-shaped plug-in frame 502, the Z-shaped plug-in frame 502 can be reset to fit against the outer wall of the protective sleeve 401. When the cold pressing head 3 descends to a predetermined position, its outer wall will simultaneously contact and push open a plurality of Z-shaped plug-in frames 502. Since the Z-shaped plug-in frames 502 are distributed in different orientations, the cold pressing head 3 must be in the correct position to simultaneously push open and insert the Z-shaped plug-in frames 502 into the corresponding annular docking grooves 403 in the elastic cushion plate 402. If the cold pressing head 3 is uneven, it cannot ensure that all the Z-shaped plug-in frames 502 can be smoothly pushed out simultaneously. The staff can observe the situation of the Z-shaped plug-in frames 502 being pushed out to determine whether the cold pressing head 3 inside the protective sleeve 401 is offset, or trigger a sensor (such as a microswitch, displacement sensor, etc., which are not explicitly mentioned in the original description, but such components can be added later for automated detection) connected to the Z-shaped plug-in frame 502 through the movement of the Z-shaped plug-in frame 502. After the sensor detects the movement of each Z-shaped plug-in frame 502, it transmits a signal to the control system. The control system determines whether the cold pressing head 3 is offset based on the received signal and takes corresponding measures, such as stopping the further descent of the cold pressing head 3, issuing an alarm to prompt the operator to check, etc.

[0043] In a further embodiment of the present invention, a slot 407 adapted to the clamping jaw 6 is formed through the protective sleeve 401. One end of the clamping jaw 6 passes through the slot 407 and abuts against the Z-shaped plug-in frame 502. A wedge-shaped abutting block 408 is fixedly connected to the top of the protective sleeve 401. A wedge-shaped groove 507 for abutting against the wedge-shaped abutting block 408 is formed at the top of the Z-shaped plug-in frame 502. Specifically, the position and number of the slots 407 are determined according to the layout of the clamping jaws 6 to ensure that each clamping jaw 6 can extend from the slot 407 and act on the blank after pressing and forming. Before the cold pressing head 3 presses the raw material, the clamping jaws 6 are pushed into the slots 407 to prevent the clamping jaws 6 from affecting the normal progress of the pressing operation. When the cold pressing head 3 presses down from above the Z-shaped plug-in frame 502, the two are inclined and abutted against each other. When the cold pressing head 3 squeezes the Z-shaped plug-in frame 502 upward from below, the two are horizontally abutted against each other. First, the guide plate is lifted to a corresponding height so that the guide plate cannot continue to move upward. Then, when the cold pressing head 3 moves upward alone, it drives the Z-shaped plug-in frame 502 to move upward for a period of time. The cooperation between the wedge-shaped abutting block 408 and the wedge-shaped groove 507 allows the Z-shaped plug-in frame 502 to gradually move away from above the cold pressing head 3 while being lifted, so that the cold pressing head 3 can complete the reset.

[0044] In a further embodiment of the present invention, a resisting rod 302 is vertically and fixedly connected to the bottom of the cold pressing head 3. A jack 203 adapted to the resisting rod 302 is vertically formed in the center of the die base 2. A plurality of annularly distributed supporting rods 7 are inserted through the die base 2. An annular abutting groove 303 for abutting against one end of the supporting rod 7 is formed on the outer side of the resisting rod 302. The bottom surface of the retaining ring 201 abuts against the other end of the supporting rod 7. Specifically, when the cold pressing head 3 descends under the drive of the telescopic cylinder 304, it transmits the pressure to the supporting rod 7 through the resisting rod 302 and the annular abutting groove 303. As a supporting component, the supporting rod 7 disperses the pressure to each part of the die base 2, thereby improving the bearing capacity and stability of the die base 2. At the same time, the retaining ring 201 is also more firmly installed on the die base 2 through the supporting action of the supporting rod 7.

[0045] In a further embodiment of the present invention, an air chamber 8 is provided outside the protective sleeve 401 below the Z-shaped plug-in frame 502. A piston 801 connected to the Z-shaped plug-in frame 502 is installed in the air chamber 8. A gas storage channel 204 is provided at the edge of the retaining ring 201. One end of the gas storage channel 204 is connected to the air chamber 8 through an air delivery hose 208, and a cushion block 205 is movably inserted at the opening of the other end. When the Z-shaped plug-in frame 502 moves upward, the cushion block 205 moves away from above the supporting rod 7. Specifically, the power for the piston 801 to move in the air chamber 8 comes from the up and down movement of the Z-shaped plug-in frame 502. The gas storage channel 204 is provided at the edge of the retaining ring 201, and one end of it is connected to the air chamber 8 through the air delivery hose 208. In this way, the change in gas pressure in the air chamber 8 can be quickly transmitted to the gas storage channel 204, and then act on the cushion block 205. During the cold pressing process, the cushion block 205 is located above the supporting rod 7, and one end of the supporting rod 7 abuts against the cushion block 205, lifting the retaining ring 201 to an appropriate height. However, when the cold pressing head 3 drives the Z-shaped plug-in frame 502 to move upward after the cold pressing is completed, since the piston 801 in the air chamber 8 moves upward, the gas pressure inside the air chamber 8 changes, and the gas in the gas storage channel 204 causes the cushion block 205 to move away from above the supporting rod 7. That is, at this time, one end of the supporting rod 7 directly abuts against the inside of the opening of the gas storage channel 204, causing the entire retaining ring 201 to descend, exposing the edge of the blank, which provides convenience for the subsequent clamping of the blank by the clamping jaws 6.

[0046] In a further embodiment of the present invention, an annular accommodation cavity 206 is opened in the mold base 2. The retaining ring 201 is located in the annular accommodation cavity 206, and a card slot 207 adapted to the gas storage channel 204 is opened on the inner wall of the annular accommodation cavity 206. Specifically, the purpose of the annular accommodation cavity 206 is to provide a space to accommodate the retaining ring 201 and ensure that the retaining ring 201 can be stably installed on the mold base 2 through the respective supporting rods 7. The gas storage channel 204 not only transports and stores gas but also can be inserted into the card slot 207 to prevent the retaining ring 201 from deflecting in the mold base 2, improving the stability of the device.

[0047] In a further embodiment of the present invention, an anti-detachment pin 601 is installed through one end of the clamping jaw 6 that abuts against the Z-shaped plug-in frame 502. A sliding groove 409 for the anti-detachment pin 601 to move horizontally is opened in the slot 407. Specifically, the anti-detachment pin 601 ensures the stable connection between the clamping jaw 6 and the Z-shaped plug-in frame 502, prevents the clamping jaw 6 from accidentally detaching when subjected to lateral force or vibration, improves the reliability and safety of the equipment, and ensures the smooth progress of the pressing and clamping processes.

[0049] S1. Load the mixed raw materials into the mold cavity 202 on the mold base 2;

[0050] S2. Start the telescopic cylinder 304 to push the cold pressing head 3 to drive the elastic backing plate 402 and the protective sleeve 401 to descend until the cold pressing head 3 descends alone within the protective sleeve 401;

[0051] S3. When the cold pressing head successfully pushes open the offset determination assembly 5, press the raw material in the die cavity 202;

[0052] S4. After the saw blade blank is pressed and formed, raise the cold pressing head 3, and use the reset of the offset determination assembly 5 to make the clamping jaws 6 clamp the saw blade blank.

Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
