Description

Technical Field

[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, and it can only be completed in steps by inefficient manual methods. When operating this product manually, in order to ensure that the powder can evenly wrap the matrix, it must first be manually laid and assisted by simple machinery. Specifically, the operator will evenly spread the powder around the matrix, 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

[0004] This application is implemented through the following technical solutions: A diamond saw blade manufacturing device comprises an upper die core, an upper punch, an outer die, a lower die core and a lower punch which are coaxially arranged, 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 a 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 is close to 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.

[0005] By adopting the above technical scheme, the powder in the diamond powder trough is shaken and becomes looser, which is convenient for the powder to enter the upper pressure area, and can use inertia to quickly turn over the substrate and enter the upper pressure area, so that the powder coverage of the diamond saw blade during the manufacturing process is more uniform, which solves the problems of inadequate turning of powder, lack of material, incompleteness and low density in the prior art; specifically, the up and down movement of the upper mold core and the upper punch die are driven by the upper force device and the upper punch device respectively, which ensures the precise control of the mold and improves the molding accuracy; the lower mold core is fixed on the support seat, so that the position of the lower mold core is stable and the deviation caused by position change is avoided; the outer mold is moved up and down under the action of the pushing device, which is convenient for adjusting the space in the mold to adapt to substrates of different sizes, and the powder can be enclosed between the upper punch die and the upper punch die, simplifying the operation process; the lower punch die is slidably sleeved on the punch seat, so that the lower punch die can be flexibly The invention can be moved to adapt to different operation requirements. More importantly, it provides an operating space for the compression energy storage between the punch seat and the lower punch, so that the energy can be stored with the help of the above-mentioned power of the lower punch device, and there is no need to increase additional power to achieve the shaking of the powder, which reduces energy consumption and reduces the production cost. The elastic member between the punch seat and the lower punch is compressed and stored when the punch seat is close to the lower punch. When the set distance is reached, the elastic potential energy is intermittently released through the pause device, so that the lower punch is prompted to intermittently pause in the specified upward movement range, thereby causing the powder in the diamond powder groove to shake and become looser, which is convenient for the powder to enter the upper pressure area, and can use inertia to 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.

[0006] Optionally, a slide groove is provided at the lower end of the lower punch, and the punch seat is slidably connected in the slide groove.

[0007] By adopting the above technical solution, the relative movement between the lower punch and the punch seat is more stable and reliable, avoiding equipment failure 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 the stability and consistency of the entire pressing process.

Specifically, the coordinated action of the stop pin, the locking plate and the lever enables the lower punch to pause intermittently within the specified upward movement range, causing the powder in the diamond powder groove 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 flip 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 clamped 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. During the upward movement, the transmission pin on the lever also moves upward and pushes the stop pin to move horizontally in the oblique groove, disengaging from the ratchet to release the elastic energy and enter the next energy release cycle.

During the production process, the powder is covered more evenly, 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.
