Description

Technical Field

[0001] This utility model relates to the technical field of metal forging and pressing equipment, specifically to an in-mold deburring device. Background Technology

[0002] In metal forging, deburring is a crucial step in ensuring product precision and surface quality. Early deburring of metal parts relied primarily on manual grinding, using tools such as sandpaper and files to manually remove burrs generated after stamping or forging. This method was extremely inefficient, with an average daily throughput of less than 500 pieces per person. Furthermore, the grinding quality was highly dependent on the operator's experience, resulting in poor product consistency and a high risk of surface scratches due to uneven force. With the development of industrial automation, single-station mechanical grinding equipment, such as stationary grinding machines and vibratory grinding machines, gradually emerged.

[0003] Currently, continuous forging processes for metal materials such as aluminum alloys and stainless steel are widely used in automotive parts, electronic components, and other fields. However, in existing continuous forging production lines, the deburring process is still mainly based on an "offline single-station" model. This means that after the raw material is annealed and softened, it is first punched with a stamping die to complete the external shape and internal holes, then transferred to a separate grinding station to remove burrs, and finally returned to the forging production line for further processing. This process has three major drawbacks: First, the process is interrupted, requiring additional workpiece transfer equipment and manpower, resulting in a process time extension of more than 30% and a 25% increase in labor costs; second, when the workpiece re-enters the forging die after offline grinding, it is prone to surface damage due to positioning deviations, with a defect rate as high as 8%; third, the single-station grinding equipment requires separate parameter adjustments, making it difficult to synchronize with the continuous forging cycle, thus hindering the improvement of the automation level of the entire production line. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an in-mold deburring device that integrates with continuous forging dies, enables simultaneous forging and deburring operations, reduces process costs, and improves product consistency. It solves the problems of process disconnection, time-consuming transfer, high product defect rate, and poor automation adaptability caused by offline deburring processes in existing continuous forging production lines.

[0005] To achieve the above-mentioned goals of integrating into continuous forging dies, realizing simultaneous "forging-deburring" operations, reducing process costs, and improving product consistency, this utility model provides the following technical solution: an in-die deburring device, including an upper die base, a lower die base, and a lower die insert fixedly installed on the top of the lower die base. A first channel is provided on one side of the top of the lower die insert, and a product strip is provided on the top of the lower die insert perpendicular to the direction of the first channel. A grinding mechanism mounting seat is fixedly installed in the first channel, and a grinding slider is slidably connected to the side of the grinding mechanism mounting seat near the lower die insert. A grinding disc is detachably fixed on the grinding slider.

[0006] Preferably, the grinding mechanism mounting base has a dovetail groove extending horizontally on the side near the grinding slider, and the grinding slider has a dovetail boss integrally formed on the side near the grinding mechanism mounting base that matches the dovetail groove.

[0007] Preferably, an air extraction pipe is provided in the dovetail groove along the direction of the first channel.

[0008] Preferably, the air extraction pipe passes through the dovetail boss along the dovetail groove.

[0009] Preferably, a grinding cylinder for driving the grinding slider is provided on the dovetail boss.

[0010] Preferably, a second channel is provided below the upper mold base at the position corresponding to the first channel on the lower mold base.

[0011] Preferably, the second channel is provided with a pressing block and a pressing cylinder for driving the pressing block.

[0012] Preferably, the lower mold base is provided with several venting channels.

[0013] Preferably, the grinding disc and the pressure block are positioned opposite each other, and the grinding disc slides and grinds in the central area of ​​the pressure block.

[0014] Preferably, the upper surface of the lower mold base protrudes slightly beyond the lower mold insert to form a free surface, and the outer end of the air extraction pipe extends out of the free surface.

[0015] Compared with the prior art, the present invention provides an in-mold deburring device, which has the following beneficial effects: This in-mold deburring device fixes the grinding mechanism mounting base to one side of the lower die insert of the lower die base. The grinding cylinder drives the grinding slider to slide along the grinding mechanism mounting base, so that the grinding disc reciprocates to grind the bottom of the workpiece in the strip channel. At the same time, the pressing cylinder of the upper die assembly drives the pressing block to press and fix the strip. This realizes the synchronous operation of "forging-deburring" in the mold. Compared with the traditional offline single-station grinding, it eliminates the workpiece transfer link, shortens the process time, saves labor costs and reduces costs. Moreover, the grinding process is synchronized with the forging cycle, and there is no need to adjust the equipment parameters separately, which greatly improves the overall efficiency of the continuous forging production line.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example

[0020] like Figure 1 and Figure 3 As shown, an in-mold deburring device includes an upper mold base 3, a lower mold base 1, and a lower mold insert 2 fixedly installed on the top of the lower mold base 1. A first channel 11 is provided on the top of one side of the lower mold insert 2. A product strip 4 is provided on the top of the lower mold insert 2 perpendicular to the first channel 11. A grinding mechanism mounting base 5 is fixedly installed in the first channel 11. A grinding slider 54 is slidably connected to the side of the grinding mechanism mounting base 5 near the lower mold insert 2. A grinding disc 55 is detachably fixed on the grinding slider 54. The grinding mechanism mounting base 5 is fixedly installed in the first channel 11 of the lower mold insert 2, serving as a support base for the grinding module. It provides a stable mounting platform to ensure that the grinding slider 54 and the grinding disc 55 maintain precise positions during forging. The grinding slider 54 is slidably connected to the side of the grinding mechanism mounting base 5 near the lower mold insert 2, realizing reciprocating motion along the direction of the first channel 11. The grinding disc 55 is driven to contact the edge of the workpiece to remove burrs. The grinding disc 55 is detachably fixed on the grinding slider 54 and directly contacts the edge of the workpiece to remove burrs through friction or cutting. Different materials or grit sizes of grinding discs 55 can be replaced according to the type of burr. The detachable design supports quick replacement and adapts to the production of various workpieces. The grinding disc 55 removes burrs through reciprocating motion. Through in-mold integrated grinding, the forging and deburring processes are seamlessly connected, shortening the production cycle. The sliding fit between the grinding slider 54 and the mounting base ensures that the grinding disc 55 is always perpendicular to the edge of the workpiece, improving the deburring quality. The detachable grinding disc 55 design supports quick changeover and meets the needs of multi-variety, small-batch production.

[0021] like Figure 3As shown, the grinding mechanism mounting base 5 has a dovetail groove 51 extending horizontally on the side near the grinding slider 54, and the grinding slider 54 has a dovetail boss 52 integrally formed on the side near the grinding mechanism mounting base 5 that matches the dovetail groove 51; the extension direction of the dovetail groove 51 is consistent with the grinding direction, ensuring that the grinding slider 54 can only reciprocate along the preset path, avoiding deviation that would cause the grinding disc 55 to deviate from the position of contact with the workpiece.

[0022] like Figure 3 As shown, an air extraction pipe 53 is provided in the dovetail groove 51 along the direction of the first channel 11; the air extraction pipe 53 passes through the dovetail boss 52 along the dovetail groove 51; the air extraction pipe 53 is embedded in the dovetail groove 51 and extends along the direction of the first channel 11 to ensure that it coincides with the path of the grinding area; the metal chips and burr residues generated during the grinding process are directly sucked into the air extraction pipe 53 by the negative pressure airflow to avoid the accumulation of chips on the surface of the workpiece or the gap of the mold.

[0023] like Figure 3 As shown, a grinding cylinder 56 for driving the grinding slider 54 is provided on the dovetail boss 52; the grinding cylinder 56 is used to drive the grinding slider 54 to move repeatedly, thereby driving the grinding disc 55 on the grinding slider 54 to move repeatedly, so as to ensure that the grinding disc 55 fully grinds the product.

[0024] like Figure 1 As shown, a second channel 31 is provided below the upper mold base 3 at the position corresponding to the first channel 11 on the lower mold base 1; the second channel 31 is located at the bottom of the upper mold base 3 and is completely aligned with the first channel 11 in the vertical direction to form a continuous space that runs through the upper and lower parts, so as to prevent the material pressing from being skewed when the upper mold base 3 is pressed down, which would cause the deburring to be unstable and affect the deburring quality.

[0025] like Figure 1 and Figure 2 As shown, the second channel 31 is equipped with a pressing block 61 and a pressing cylinder 6 for driving the pressing block 61; the pressing cylinder 6 drives the pressing block 61 to press the product to ensure the stability of the product during deburring, thereby ensuring the quality of deburring.

[0026] like Figure 2 As shown, the lower mold base 1 is provided with four exhaust channels 13; the four exhaust channels 13 exhaust air evenly, and at the same time, the lower mold base 1 is designed to be lightweight while ensuring its strength, thereby reducing material costs.

[0027] like Figure 2 As shown, the grinding disc 55 and the pressure block 61 are positioned opposite each other, and the grinding disc 55 slides and grinds in the central area of ​​the pressure block 61. The axis of the grinding disc 55 coincides with the axis of the pressure block 61, so that the pressure is applied perpendicularly to the surface of the workpiece, avoiding uneven grinding caused by lateral force, and further ensuring the quality of grinding and deburring.

[0028] like Figure 1 and Figure 2 As shown, the upper surface of the lower mold base 1 protrudes slightly from the lower mold insert 2 to form a free surface 12, and the outer end of the air extraction pipe 53 extends out of the free surface 12; the outer end of the air extraction pipe 53 extends out of the free surface 12 to ensure that the waste generated during the grinding process is directly discharged from the device, which is convenient for recycling and at the same time reduces the difficulty of cleaning the device.

[0029] In the embodiments of this utility model, both the grinding cylinder 56 and the pressing cylinder 6 are commercially available parts.

[0030] Working principle: During the transportation of the product along the product conveyor belt 4, the pressing cylinder 6 in the second channel 31 of the upper mold base 3 drives the pressing block 61 to press the product, and the grinding cylinder 56 in the first channel 11 of the lower mold base 1 drives the grinding slider 54 to slide repeatedly along the direction of the dovetail groove 51, thereby driving the grinding disc 55 to repeatedly grind the burrs on the bottom of the product. The burr waste generated during the grinding process falls into the dovetail groove 51 and is extracted and recycled by the air extraction pipe 53.

[0031] In summary, this in-mold deburring device, by fixing the grinding mechanism mounting base 5 to one side of the lower die insert 2 of the lower die base 1, uses the grinding cylinder 56 to drive the grinding slider 54 to slide along the grinding mechanism mounting base 5, so that the grinding disc 55 reciprocates to grind the bottom of the workpiece in the strip channel. At the same time, the pressing cylinder 6 of the upper die assembly drives the pressing block 61 to press and fix the strip, realizing the synchronous in-mold operation of "forging-deburring". Compared with the traditional offline single-station grinding, it eliminates the workpiece transfer link, shortens the process time, saves labor costs and reduces costs. Moreover, the grinding process is synchronized with the forging cycle, and there is no need to adjust the equipment parameters separately, which greatly improves the overall efficiency of the continuous forging production line.
