Description

Technical Field

[0001] The present application relates to the technical field of diamond saw blade manufacturing equipment, and in particular to a diamond saw blade manufacturing device. Background Art

[0002] As an important cutting tool, diamond saw blades are widely used in the processing of hard materials such as stone, ceramics, and concrete. In the manufacturing process of diamond saw blades, matrix production and powder sintering are one of the key processes. Among them, the process of powder wrapping the matrix is ​​particularly critical. When the powder wrapping width exceeds 20mm, the poor natural fluidity of the powder determines that it is impossible to achieve full coverage of the powder by automatic and semi-automatic methods. It can only be completed in steps by manual methods with low efficiency. When operating this product manually, in order to ensure that the powder can evenly wrap the matrix, it is necessary to first spread the material manually and use simple mechanical assistance. Specifically, the operator will spread the powder evenly around the matrix and use simple tools for preliminary compaction, and then use the mold for final pressing and sintering. However, the current process still has defects in actual production. Among them, the laying of powder is not only inefficient, but also prone to problems such as uneven powder coverage, material shortages and low density, which affect product quality and production efficiency. Especially in large-scale production, these problems are more significant. There is an urgent need for a device that can automatically complete powder laying to improve production efficiency and product quality. Summary of the Invention

[0003] In order to overcome the shortcomings of the above-mentioned prior art, the present application provides a diamond saw blade manufacturing device, which stores energy and intermittently releases elastic potential energy during the upward movement of the lower punch, so that the powder in the diamond powder trough is shaken and becomes looser, making it easier for the powder to enter the upper pressure area. With the help of inertia, it can quickly flip over the base and enter the upper pressure area, thereby making the powder coverage of the diamond saw blade more uniform during the manufacturing process, solving the problems of material shortage, incompleteness and low density caused by inadequate flipping of the powder in the prior art.

[0004] This application is achieved through the following technical solutions:

[0005] A diamond saw blade manufacturing device includes a coaxially arranged upper die core, an upper punch, an outer die, a lower die core and a lower die, wherein the upper die core is powered by an upper force-applying device to achieve up and down movement; the upper punch is powered by an upper punching device to achieve up and down movement, and the lower die core is fixed on a support seat; the outer die is moved up and down under the action of a pushing device; the lower punch is slidably sleeved on the punching seat; the punching seat is powered by a lower punching device to achieve up and down movement; an elastic member is provided between the punching seat and the lower punch, and the elastic member is used to compress and store energy when the punching seat approaches the lower punch; a pause device is provided between the support seat, the lower punch and the punching seat, and the pause device is used to enable the elastic member to intermittently release elastic potential energy within a moving distance set by the lower punch.

When the set distance is reached, the elastic potential energy is intermittently released through the pause device, prompting the lower punch to achieve intermittent pauses in the specified upward range, thereby causing the powder in the diamond powder trough to shake and become looser, making it easier for the powder to enter the upper pressure area, and with the help of inertia, it can quickly turn over the substrate and enter the upper pressure area, thereby making the diamond saw blade more evenly covered with powder during the production process, so as to achieve uniform distribution of powder, ensure that the powder can fully cover the substrate and the cutter head, and improve the quality and efficiency of sintering.

[0007] Optionally, a slide groove is provided at the lower end of the lower punch, and the punching seat is slidably connected in the slide groove.

[0008] By adopting this technical solution, the relative movement between the lower punch and the punch seat becomes smoother and more reliable, avoiding equipment failures caused by jamming or misalignment between the two, and improving production efficiency and product quality. Specifically, the design of the slide effectively ensures that the punch seat always moves along the predetermined path during the sliding process, thereby ensuring stability and consistency throughout the entire pressing process.

[0009] Optionally, the elastic member is a spring, and a positioning shoulder is provided on the stamping seat; the spring is sleeved on the stamping seat and placed between the lower punch and the positioning shoulder.

Specifically, the coordinated action of the stop pin, the locking plate and the shift rod enables the lower punch to pause intermittently within the specified upward movement range, causing the powder in the diamond powder trough to shake and become looser, making it easier for the powder to enter the upper pressure area, and with the help of inertia, it can quickly turn over the substrate and enter the upper pressure area, thereby making the diamond saw blade more evenly covered with powder during the production process, thereby ensuring the powder Evenly cover the base and the cutter head to reduce the problems of material shortage and incompleteness. Under the action of spring tension, the transmission pin is at the lower end of the oblique groove on the stop pin. At this time, the stop pin is engaged in the ratchet of the locking plate, so that the lower punch cannot move upward. As the punch seat moves upward, the spring is further compressed to store energy. In the upward process, the transmission pin on the shift rod also moves upward and pushes the stop pin to move horizontally in the oblique groove, disengaging from the ratchet to realize the release of elastic energy and enter the next energy release cycle. It should be noted that the pause device can also limit the lower punch and the punch seat to prevent the punch seat from falling off from the lower punch, which is convenient for later installation.

At the same time, this detachable design also facilitates the rapid replacement of levers of different specifications or models, enhancing the adaptability and flexibility of the equipment.

[0023] Optionally, the locking plate is a disc-shaped structure; there are at least two pairs of stop pins and shift rods, which are evenly distributed around the locking plate.

[0042] like Figures 2 and 3As shown, the stamping seat 6 includes a stamping seat 6 body, and a positioning shoulder 61 is provided at the bottom of the stamping seat 6 body.

During the production process, the powder coverage is more uniform, thereby ensuring that the powder evenly covers the base 11 and the cutter head, reducing the problems of material shortage and incompleteness. Specifically, under the action of the tension of the spring 7, the transmission pin 91 is at the lower end of the oblique groove 102 on the stop pin 10. At this time, the stop pin 10 is clamped in the ratchet 81 of the locking plate 8, so that the lower punch 5 cannot move upward. As the punch seat 6 moves upward, the spring 7 is further compressed to store energy. In the upward process, the transmission pin 91 on the shift rod 9 also follows the upward movement and pushes the stop pin 10 to move horizontally in the oblique groove 102, disengaging from the ratchet 81, realizing the release of elastic energy and entering the next energy release cycle; and the transmission pin 91 can also limit the moving range of the stop pin 10, thereby realizing the limitation of the lower punch 5 and the punch seat 6, preventing the punch seat 6 from falling off from the lower punch 5, and facilitating later assembly.

[0045] like Figures 3 and 4As shown, the cross-section of the stop pin 10 is a square structure, made of high-strength alloy steel, and has good wear resistance and deformation resistance; the inner wall of the lower punch 5 is fixed with a guide seat 52 by bolts or welding, and a guide hole is provided in the guide seat 52, and the stop pin 10 is slidably connected in the guide hole to ensure flexible lateral movement; an oblique groove 102 is provided in the middle of the stop pin 10, which cooperates with the transmission pin 91 on the shift rod 9 to realize the release of elastic potential energy.

[0047] like Figure 1 As shown, the locking plate 8 is a disc-shaped structure, made of high-strength alloy steel, and has good wear resistance and deformation resistance; the locking plate 8 is fixed to the support seat 31 by welding or threaded connection to ensure stability; there are at least two pairs of stop pins 10 and shift rods 9, evenly distributed around the circumference of the locking plate 8; the locking plate 8 is made of high-strength alloy steel, and has good wear resistance and deformation resistance; the number of stop pins 10 and shift rods 9 can be adjusted as needed to adapt to different usage scenarios.

The shift rod 9 is connected to the mounting column 62 by screws or buckles, which is convenient for disassembly and maintenance.

[0049] In addition, if Figure 5 As shown, in order to better cooperate with this device, the diamond saw blade base 11 can be designed to have a number of turning holes 111 in the powder stamping area, so that when the diamond saw blade base 11 sinks into the powder, the powder can have a larger channel to turn up, ensuring that the powder can cover the base 11 and the cutter head, thereby improving production efficiency and product quality; and in order to determine the position relationship between the lower mold core 3 and the lower punch 5, a distance sensor 63 is provided on the inner wall of the lower punch 5. The distance sensor 63 can be a laser distance sensor 63, which transmits the sensed position signal to the control unit of the device, and the control unit issues an instruction to control the action of the actuator of the upper punching device 13.

[0050] When the device is running, Figures 6-8As shown, first install the diamond saw blade base 11 on the positioning column of the upper mold core 1, and use the pneumatic upper force device 12 to push the upper mold core 1 downward to clamp the diamond saw blade base 11 between the upper mold core 1 and the lower mold core 3; then start the pushing device 14 to push the outer mold 4 upward to cover the upper punch 2 and the lower punch 5 in their inner cavity to seal the powder; then start the lower punch device 15 to push the lower punch 5 upward. Within the specified range of the lower punch 5 moving upward, the lower punch 5 is intermittently paused under the action of the spring 7 machine pause device, thereby making The powder in the diamond powder trough shakes within this moving distance and becomes looser, which facilitates the powder to enter the upper pressure area and can use inertia to quickly flip over the base 11 and enter the upper pressure area, thereby making the powder coverage of the diamond saw blade more uniform during the manufacturing process, so as to achieve uniform distribution of the powder and ensure that the powder can fully cover the base 11 and the cutter head; after the lower punch 5 has passed the specified shaking distance, the upper punch device 13 is started, pushing the upper punch 2 to move downward, and cooperating with the upper punch 2 to extrude the powder to complete the powder compaction process, which can be done here.

More importantly, it provides an operating space for the compression energy storage between the punching seat 6 and the lower punch 5, so that Energy can be stored with the help of the above-mentioned power of the lower punching device 15, and there is no need to increase additional power to achieve the shaking of the powder, which reduces energy consumption and reduces production costs; the elastic part between the punching seat 6 and the lower die 5 is compressed and stored when the punching seat 6 is close to the lower die 5. When the set distance is reached, the elastic potential energy is intermittently released through the pause device, prompting the lower die 5 to achieve intermittent pauses in the specified upward movement range, thereby causing the powder in the diamond powder groove to shake and become looser, making it convenient for the powder to enter the upper pressure area, and with the help of inertia, it can quickly turn over the base 11 and enter the upper pressure area, thereby making the diamond saw blade more evenly covered with powder during the production process, so as to achieve uniform distribution of powder, ensure that the powder can fully cover the base 11 and the cutter head, and improve the quality and efficiency of sintering.
