Description

[0002] With the rapid development of science and technology, the quality and precision requirements for workpieces have been improved, and the entire processing of the workpiece often requires multiple steps to complete.

[0003] With regard to the prior art, in most workpiece forming molds, it is often sufficient to simply match the mold cavity formed between the movable mold component and the fixed mold component with the shape of the product. However, for some complex parts or long strip-shaped parts, due to the clamping force between the die-cast product and the mold cavity, when the product is separated from the mold cavity by the push rod on the movable mold component, the product is easily deformed and the product quality is affected. At the same time, during the clamping and cutting process of the workpiece on the fixture, the workpiece itself often needs to be clamped in position, resulting in deeper clamping marks on the workpiece due to the larger cutting force of the milling cutter. When some tools are used to remove holes and burrs on the workpiece, a single blade needs to move back and forth during the cleaning process to complete the processing of the workpiece. This not only affects the service life of the tool due to wear, but also prolongs the time required for workpiece processing. Summary of the invention

[0048] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0049] like Figures 1 to 8 As shown, a workpiece processing device of the present invention comprises: a workpiece forming mold 200, a fixture 300 and a processing tool 400, characterized in that: the workpiece 100 is in the shape of an elongated strip, and a plurality of long plates 110 are arranged at the end of the workpiece 100, each long plate 110 does not abut against each other and is provided with waist-shaped holes 111, and the waist-shaped holes 111 are linearly distributed; the workpiece forming mold 200 comprises a fixed mold assembly 260 and a movable mold assembly 210, the movable mold assembly 210 and the fixed mold assembly 260 form a mold cavity 270, the mold cavity 270 comprises a main cavity 271 and a secondary cavity 273, the main cavity 271 is used to form the workpiece 100, and both sides of the main cavity 271 and the end away from the long plate 110 are provided with reserved cavities 272, the secondary cavity 273 is connected to the ends of the plurality of long plates 110, and a relatively placed forming block 211 is movably arranged on the movable mold assembly 210, and the forming Block 211 is used to approach each other and be movably inserted in the main cavity 271; the fixture 300 includes a first fixture 310 and a second fixture 350, and the first fixture 310 is provided with a first clamping block 320, and the first clamping block 320 is used to clamp the product die-cast in the secondary cavity 273; the second fixture 350 is provided with a second clamping block 360, and the second clamping block 360 is used to clamp on a plurality of long plates 110; the processing tool 400 is provided with a plurality of processing heads 410, and the processing heads 410 are arranged in an array, and the processing heads 410 are provided with a first processing part 411 and a second processing part 412, and an arc surface 413 is connected between the first processing part 411 and the second processing part 412, and the axial distance between the first processing part 411 and the rotating shaft on the processing tool 400 is smaller than the axial distance between the second processing part 412 and the rotating shaft on the processing tool 400.

[0050] The workpiece 100 processing device of the present invention is composed of three parts: die casting of the workpiece 100, clamping and cutting of the reserved cavity 272 and the auxiliary cavity 273, and tool cutting. Among them, for the long strip of the product, a main cavity 271 and an auxiliary cavity 273 are provided in the mold cavity 270 formed between the movable mold component 210 and the fixed mold component 260. The main cavity 271 is used to form the required product. Considering that when the product is die-casted in the mold cavity 270, a certain clamping force will be generated between the product and the mold cavity 270 due to thermal expansion and contraction, and because there are When a plurality of long strips of long plates 110 are used to push the product out of the mold cavity 270 by using the push rod on the movable mold assembly 210, if the push rod directly acts on the end of the product long plate 110, the product is easily deformed in the process of being out of the mold cavity 270, thereby affecting the quality of the product. Therefore, a sub-cavity 273 is provided at the end of the main cavity 271 close to the long plate 110, and a reserved cavity 272 is provided around the main cavity 271, so that when the molten metal enters the mold cavity 270, it can flow into the reserved cavity 272, the main cavity 271 and the like. and the auxiliary cavity 273, so that the desired product is die-casted as a whole with the reserved cavity 272 and the auxiliary cavity 273. When the push rod pushes the product out of the mold cavity 270, it can act on the auxiliary cavity 273 and the reserved cavity 272 at the same time, so that the push rod is evenly stressed on the product die-cast in the reserved cavity 272, the main cavity 271 and the auxiliary cavity 273, ensuring that the workpiece 100 will not be deformed when it is out of the mold cavity 270. The principle of the push rod in the workpiece forming mold 200 of the present invention to push the product out of the mold cavity 270 is similar to that of the push rod in the traditional mold. The principle is the same and will not be elaborated here. It should be noted that the waist-shaped hole 111 required in the die-casting workpiece 100 in the present invention is formed by relatively arranged forming blocks 211 approaching each other and finally abutting against each other to form the waist-shaped hole 111 on the workpiece 100. This design replaces the traditional single forming block 211 extending into the mold cavity 270. The relatively arranged forming blocks 211 can reduce the required displacement stroke, thereby reducing the footprint of the driving part that drives the forming block 211, and at the same time can speed up the time required for die-casting of the workpiece 100.

[0051] The movable mold assembly 210 is provided with a first driving member 220 and a second driving member 230 opposite to each other. The driving ends of the first driving member 220 and the second driving member 230 are both connected to a moving block 240 . The molding blocks 211 are respectively connected to one side of the moving block 240 close to the main cavity 271 .

[0052] Similarly, the first driving member 220 and the second driving member 230 are relatively arranged on the movable mold assembly 210. Before the movable mold assembly 210 and the fixed mold assembly 260 perform a mold closing action, the first driving member 220 and the second driving member 230 respectively drive the molding block 211 on the movable block 240 to approach each other. When the two molding blocks 211 are pressed against each other, the movable mold assembly 210 and the fixed mold assembly 260 can be molded together. The molding block 211 is designed to form the waist-shaped hole 111 required on the workpiece 100 in the mold cavity 270 during die-casting. The two relatively arranged molding blocks 211 reduce the required moving stroke compared to a single molding block 211, thereby saving the time required for die-casting of the workpiece 100.

[0053] The moving block 240 is provided with a forming column 241 on the same side as the forming block 211 , and the forming column 241 is close to the end of the workpiece 100 away from the long plate 110 ; when the moving block 240 drives the forming column 241 to approach each other, the forming column 241 is used to be movably inserted into the main cavity 271 .

[0054] The design of the molding column 241 is determined according to the required shape of the product. For products of different shapes, other required shapes can be set on the moving block 240 on the same side of the molding block 211 to meet the needs of the product. It should be noted that molding columns 241 of different lengths are designed according to the different shapes of the workpiece 100, and during the movement of the moving block 240, the molding columns 241 do not need to abut against each other, but only need to extend into a part of the main cavity 271 according to the shape required by the product.

[0055] The bottom of the moving block 240 is connected with a guide block 242 . The movable mold assembly 210 is provided with a guide groove 243 . The guide block 242 is movably engaged in the guide groove 243 .

[0056] The purpose of the moving block 240 driving the forming block 211 and the forming column 241 to move is to accurately form the required waist-shaped hole 111 or other shapes on the workpiece 100 during the die-casting process. Therefore, the guide block 242 at the bottom of the moving block 240 is movably clamped in the guide groove 243 on the movable mold assembly 210. Driven by the first driving member 220 or the second driving member 230, the moving block 240 can reciprocate along the direction of the guide groove 243, thereby driving the forming block 211 or the forming block 211 to extend into the main cavity 271, thereby avoiding the displacement of the moving block 240 during the movement process, causing the waist-shaped hole 111 and other shapes required for the product in the die-casting molding to be offset or tilted, thereby ensuring the quality of the product.

[0057] The movable mold assembly 210 and the fixed mold assembly 260 form a feed pipe 274. The fixed mold assembly 260 is provided with a through hole 262. A feed barrel 261 is installed in the through hole 262. The feed barrel 261 is connected to the feed pipe 274, and the end of the feed pipe 274 away from the feed barrel 261 is connected to the reserved cavity 272 at the end of the main cavity 271.

[0058] After the moving block 240 drives the molding block 211 and the molding column 241 to approach each other, the movable mold assembly 210 and the fixed mold assembly 260 perform a mold closing action to pour the molten metal from the feed barrel 261, and the molten metal can flow from the feed pipe 274 to the reserved cavity 272, the main cavity 271 and the auxiliary cavity 273, and finally the required product is die-cast. The setting of the discharge block 250 and the auxiliary cavity 273 avoids the formation of shrinkage holes in the die-cast product in the main cavity 271. Since the auxiliary cavity 273 needs to be separated from the main cavity 271 in the end, it will not affect the quality of the workpiece 100 itself.

[0059] After the workpiece 100 is die-cast and separated from the mold cavity 270 by the push rod, the workpiece 100 can be placed in the first fixture 310 and the second fixture 350 in the fixture 300, and the reserved cavity 272 and the auxiliary cavity 273 in the die-cast workpiece 100 are cut by the milling cutter. In order to avoid deformation of the workpiece 100 during the cutting process, the first clamping block 320 is pressed against the auxiliary cavity 273 during the clamping of the workpiece 100 by the first fixture 310 to ensure that the product is in the shape of the product and to avoid deformation of the workpiece 100 during the cutting process. To produce an offset, in the second clamping tooling 350, the second clamping block 360 is directly pressed on several long plates 110, and the clamping position of the second clamping block 360 is close to the secondary cavity 273. It should be noted that since the third clamping block 392 is directly pressed on several long plates 110, some items that can reduce the clamping marks can be installed on the third clamping block 392, such as copper sheets often used in lathe clamping, etc. These can avoid deep clamping marks when the milling cutter cuts the secondary cavity 273 on the workpiece 100, thereby improving the quality of the product.

[0060] A mounting plate 361 is provided on the fixture 300, and the first fixture 310 and the second fixture 350 are both located on the mounting plate 361. The first fixture 310 also includes: a first support block 330, a support column 331 is provided on the first support block 330, a molding pin 280 is provided on the fixed mold assembly 260, the molding pin 280 is used to be inserted into the secondary cavity 273 to form a first positioning hole 120 on the workpiece 100, and the support column 331 is inserted into the first positioning hole 120; a second support block 340, the second support block 340 is installed on the mounting plate 361, a support plate 341 is provided on the second support block 340, and a first protruding block 290 is provided in the main cavity 271, the first protruding block 290 is used to form a mounting groove 130 of the workpiece 100 away from one end of the long plate 110, and the support plate 341 is inserted into the mounting groove 130.

[0061] It should be noted that the mounting plate 361 is rotatably arranged on the fixture 300. When the mounting plate 361 is driven to rotate by the driving member on the fixture 300, the workpiece 100 on the first fixture 310 and the second fixture 350 can be rotated, so that the milling cutter can cut the workpiece 100 using different cutting processes. In the first fixture 310, the support column 331 on the first support block 330 is inserted into the first positioning hole 120, and the second support block 340 is located at the end of the workpiece 100 away from the long plate 110. The first protrusion block 290 is inserted into the mounting groove 130 on the workpiece 100, so that both ends of the workpiece 100 are fixed, and the reserved cavity 272 near the two ends of the workpiece 100 can be cut by the milling cutter to complete the first clamping and cutting of the workpiece 100.

[0062] The second fixture tooling 350 includes: a third support block 370, on which a plurality of second protruding blocks 371 are provided, and a groove 372 is formed between each adjacent two second protruding blocks 371, and the distance in the width direction of the bottom of the groove 372 is equal to the width of the long plate 110; a fourth support block 380, which is installed on the mounting plate 361 and is located on the side away from the third support block 370, and a fixing column 381 is connected to the fourth support block 380, and a second positioning hole 140 is formed on the end of the workpiece 100 away from the long plate 110, and the fixing column 381 is inserted into the second positioning hole 140; a limit block 382, ​​which is fixed on the mounting plate 361, and the limit block 382 is used to limit the movement of the workpiece 100 along its width direction.

[0063] The second clamp tooling 350 is mainly used to separate the secondary cavity 273 from the main cavity 271, so the second clamping block 360 is required to press on several long plates 110. At the same time, when fixing the workpiece 100, the distance in the bottom width direction of the groove 372 on the third support block 370 is equal to the width of the long plate 110, that is, several long plates 110 can be placed in the groove 372 and each long plate 110 is fixed on the third support block 370. Similarly, the fourth support block 380 is set at the end of the workpiece 100 away from the long plate 110 to ensure that when the milling cutter cuts the secondary cavity 273, the other end of the workpiece 100 will not be offset. At the same time, the limit block 382 is against both sides of the width direction of the workpiece 100, which can limit the movement of the workpiece 100 along its width direction, ensuring that the workpiece 100 maintains stability when being cut, and finally the secondary cavity 273 is separated from the main cavity 271 by the milling cutter, thereby completing the second clamping and cutting of the workpiece 100.

[0064] A third driving member 390 is provided on the mounting plate 361, a connecting plate 391 is provided on the third driving member 390, a third clamping block 392 is provided on both the first clamping tool 310 and the second clamping tool 350, the first clamping block 320, the second clamping block 360 and the third clamping block 392 are all hinged on the connecting plate 391, and the ends of the first clamping block 320, the second clamping block 360 and the third clamping block 392 away from the workpiece 100 are all hinged to the driving end of the third driving member 390.

[0065] In addition to the first clamping block 320 and the second clamping block 360, a third clamping block 392 is provided on each of the above-mentioned support blocks. The third driving member 390 is utilized to drive the first clamping block 320, the second clamping block 360 and the third clamping block 392 to rotate relative to the connecting plate 391, thereby clamping the workpiece 100 on the first fixture 310 and the second fixture 350, thereby preventing the workpiece 100 from being offset or flipped during the cutting process, thereby ensuring the smoothness of cutting of the workpiece 100 by other cutting tools such as a milling cutter.

[0066] After the first fixture 310 and the second fixture 350 use the milling cutter to cut off the reserved cavity 272 and the auxiliary cavity 273 on the workpiece 100, the processing tool 400 can be installed on the tool holder so that the processing tool head 410 extends into the waist-shaped hole 111 on the workpiece 100 for further cutting, wherein the processing tool heads 410 are distributed in an array. The purpose of such a design is to speed up the cutting amount of the processing tool head 410 on the workpiece 100. At the same time, the processing tool head 410 is provided with a first processing part 411 and a second processing part 412, and an arc surface 413 is provided between the first processing part 411 and the second processing part 412, and the axial distance between the first processing part 411 and the rotating shaft on the processing tool 400 is smaller than the axial distance between the second processing part 412 and the rotating shaft on the processing tool 400, that is, when the processing tool 400 cuts the inside of the waist-shaped hole 111, the first processing part 41 After cutting the inner wall of the waist-shaped hole 111, the second processing part 412 can follow the first processing part 411 to cut the inside of the waist-shaped hole 111 again, so that the processing tool 400 can realize two cuttings on the inner wall of the waist-shaped hole 111 of the workpiece 100 in one rotation. In addition, the array arrangement of the processing tool head 410 increases the cutting amount, which avoids the processing tool 400 affecting the service life of the tool itself due to the large cutting amount, and can also greatly improve the cutting speed of the workpiece 100.
