[0002] Parts are the basic units that make up mechanical products or equipment. Parts are combined and assembled to form a complete machine or product, which has an independent function or structural role.

[0003] In the process of manufacturing parts, materials need to be processed by cutting, grinding, stamping and forging. The stamping equipment is divided into upper and lower dies. During the stamping process, the automatic feeder feeds the coiled material into the die at a set pitch. The punch punches through the sheet metal to form the mounting hole. The scrap material falls through the punch hole. Other stations use the punch and die to punch out the shape of the part, bend and shape it. Different stamping dies can be used to achieve different stamping effects on the parts.

[0004] In the production of some parts, dozens of stamped parts are produced simultaneously, requiring frequent die changes to achieve mixed-line production. Traditional stamping dies are usually fixed by mechanical means such as bolts, pressure plates, and pins, which requires the use of tools to disassemble multiple fasteners one by one, which is time-consuming and can easily lead to increased downtime and decreased stamping efficiency.

[0005] Therefore, this utility model provides a stamping die for parts processing. Utility Model Content

Detailed Implementation

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figures 1 to 4 As shown, a stamping die for parts processing according to an embodiment of the present invention includes a base 1; a plurality of support rods 10 are mounted on the top of the base 1; a pressure plate 11 is mounted on the top of the support rods 10; a die 12 is mounted on the top of the base 1; two adjusting grooves 14 are provided at the bottom of the pressure plate 11 and the top of the base 1; a bidirectional lead screw 15 is rotatably connected to the middle of the adjusting groove 14; two threaded blocks 16 are threadedly connected to the middle of the bidirectional lead screw 15; the two threaded blocks 16 are arranged opposite to each other; a fixing block 17 is fixedly connected to the middle of the threaded block 16; a plurality of fixing grooves 103 are provided in the middle of the die 12 and the punch 13; one end of the bidirectional lead screw 15 passes through the middle of the base 1; the bidirectional lead screw 15... Gear 18 is fixedly connected to the end of base 1; gear 18 is rotatably connected to the end of base 1; chain 19 is installed in the middle of two gears 18; driver 101 is fixedly connected to the middle of one of gears 18; driver 101 is installed at the end of base 1; protective cover 102 is fixedly connected to the end of base 1; protective cover 102 is fixedly connected to the outside of gear 18 and driver 101; multiple fixing grooves 103 are opened at the corners of die 12 and punch 13; fixing block 17 is installed in the middle of fixing groove 103; cleaning component 2 is provided on the top of base 1; positioning component 3 is installed at the end of die 12; during operation, the plate is conveyed into die 12, and the plate is elastically positioned by positioning component 3. The control device drives the punch 13 to move downwards. Under the combined action of the punch 13 and the die 12, the sheet metal breaks and separates under shearing force. After punching, the workpiece is pushed out. During the punching process, the waste generated during the punching process is blown away and collected from the middle of the die 12 by the cleaning component 2. When the die 12 and punch 13 need to be replaced or reground during use, the control driver 101 is turned on. The output end of the driver 101 drives the gear 18 to rotate. When one gear 18 rotates, it drives the other gear 18 to rotate simultaneously through the chain 19, causing the bidirectional lead screw 15 to rotate in the adjusting groove 14. When the adjusting groove 14 rotates, it drives the two bidirectional lead screws 15 to rotate. The die 12 moves to both sides, causing the fixing block 17 to move out of the middle of the fixing groove 103, thereby quickly removing the die 12. The above operation is repeated when changing the punch 13. The above structure makes the process of changing the die 12 and the punch 13 simpler and faster. When stamping different types of parts, the die 12 and the punch 13 can be quickly changed and fixed, realizing a quick mold change operation. This reduces the tedious disassembly of various parts by traditional tools, shortens the time of frequent mold changes, and accurately fixes the die 12 and the punch 13, reducing the loosening of the die 12 and the punch 13 during the stamping process, reducing wear and damage caused by mold loosening, and extending the service life of the mold.

[0024] like Figure 2 and Figure 4As shown, the cleaning assembly 2 includes two fixing rods 21; the two fixing rods 21 are fixed to the top sides of the base 1; a cleaning tube 22 is fixed to the end of the fixing rod 21; a through groove 23 is opened in the middle of the cleaning tube 22; a first connecting tube 24 is fixed to the middle of the cleaning tube 22; an air pump 25 is fixed to the end of one of the first connecting tubes 24; the air pump 25 is installed on the side wall of the base 1; a second connecting tube 26 is fixed to the middle of the air pump 25; the second connecting tube 26 is located on the side wall of the base 1; a filter assembly 4 is installed at the end of the second connecting tube 26 and the other first connecting tube 24; during operation, during the stamping process of the parts, the air pump 25 is turned on, and the air pump 25 generates a negative pressure airflow that passes through it. One through-slot 23 enters the middle of the cleaning pipe 22, while the other through-slot 23 discharges the airflow. The discharged airflow rushes towards the stamping surface of the die 12, and the waste is blown away from the surface of the die 12. At the same time, the waste enters the cleaning pipe 22 with the negative pressure airflow and enters the first connecting pipe 24. It is filtered by the filter assembly 4. The filtered airflow is discharged through the second connecting pipe 26 and the air pump 25, thereby realizing the waste cleaning. The above structure can clean up the waste in the stamping process in time, reduce the accumulation of waste in the stamping die, reduce the problem of the die jamming, damage or reduced stamping accuracy caused by waste residue, realize the real-time cleaning of waste, and keep the stamping surface clean.

[0025] like Figure 1 and Figure 3 As shown, the positioning component 3 includes two slide rails 31; the two slide rails 31 are fixed to the ends of the punch 13; the two slide rails 31 are arranged opposite each other; a slide rod 32 is fixed to the middle of the slide rail 31; two sliders 33 are slidably connected to the middle of the slide rod 32; a first spring 34 is fixed to the side wall of the slider 33; the end of the first spring 34 is fixed to one end of the slide rail 31; a connecting rod 35 is fixed to the middle of the slider 33; a roller 36 is rotatably connected to the middle of the connecting rod 35; multiple grooves 37 are formed in the middle of the roller 36; the multiple grooves 37 are equidistantly distributed; two damping springs 38 are fixed to the middle of the grooves 37; an arc-shaped plate 39 is fixed to the end of the two damping springs 38; during operation, the plate When the material is fed to the middle of the die 12, the two sides of the plate enter between the two rollers 36, and the two sides of the plate contact the groove 37. As the size of the plate is increased, pressure is applied to the rollers 36 on both sides. At this time, the slider 33 slides in the middle of the slide bar 32, the first spring 34 elastically contracts, and at the same time, the damping spring 38 causes the groove 37 to elastically press the plate, thereby positioning the plate and maintaining the stability of the plate during stamping. The above-mentioned elastic positioning structure can adapt to plates of different materials, provide appropriate clamping force, reduce friction and scratches on the surface of the plate after positioning, protect the surface quality of the plate, and reduce the problem of deformation or cracking of the plate due to excessive clamping force.

[0026] like Figure 4As shown, the filter assembly 4 includes a fixed box 41; the fixed box 41 is fixed to the side wall of the base 1; the fixed box 41 and the air pump 25 are opposite each other; the ends of the first connecting pipe 24 and the second connecting pipe 26 are connected to the middle of the fixed box 41; a collection filter box 42 is installed in the middle of the fixed box 41; a mounting plate 43 is fixed to the side wall of the collection filter box 42; a sealing ring 44 is fixed to the inner side wall of the mounting plate 43; two buckles 45 are fixed to the side wall of the mounting plate 43; the two buckles 45 are opposite each other; two card seats 46 are fixed to the side wall of the fixed box 41; the buckles 45 and the card seats 46 are interlocked; during operation, the collection filter box 42 is installed inside the fixed box 41, and the inner side wall of the mounting plate 43 is sleeved on the outer side wall of the fixed box 41, while simultaneously... The sealing ring 44 seals the mounting plate 43 and the fixed box 41. The buckle 45 and the seat 46 interlock to fix the collection filter box 42 inside the fixed box 41. When the waste material enters the fixed box 41 with the airflow through the first connecting pipe 24, the waste material enters the collection filter box 42 and is intercepted and collected. The airflow enters the seat 46 through the collection filter box 42. Through the above structure, when the waste material is sucked into the first connecting pipe 24 with the gas, the waste material in the airflow is stored through the collection filter box 42, which reduces the blockage and wear of the waste material when it enters the second connecting pipe 26 and the air pump 25. After the waste material is collected, it can be quickly removed, reducing the operation of long-term shutdown for cleaning and improving the efficiency of stamping work.

[0027] like Figure 2 As shown, two positioning grooves 5 are opened in the middle of the base 1 and the pressure plate 11; the positioning grooves 5 are arranged in a cross shape; two positioning blocks 51 are fixedly connected in the middle of the die 12 and the punch 13; the positioning blocks 51 are installed in the middle of the positioning grooves 5; when the die 12 or the punch 13 is installed, the positioning blocks 51 are placed in the corresponding positions of the positioning grooves 5, so that the positioning blocks 51 enter the interior of the positioning grooves 5, thereby positioning the die 12 or the punch 13. Through the above structure, the die can be quickly positioned during mold installation, so that the die 12 and the punch 13 are accurately aligned after installation, reducing the error caused by the offset of the die 12 and the punch 13 during the stamping process, and maintaining the accuracy of the stamping size and shape.

[0028] like Figure 4 As shown, a baffle 6 is fixedly connected to the middle of the cleaning pipe 22; the baffle 6 is set at an angle; the baffle 6 is set at the bottom of the through groove 23; during operation, when collecting waste, the baffle 6 intercepts the waste in the airflow and effectively collects the waste. The above structure can reduce the waste from falling directly into the processing area when it is sucked in, guide the airflow, and make the fertilizer accurately enter the interior of the cleaning pipe 22.

[0029] like Figure 3As shown, a rubber pad 7 is fixedly connected to the middle of the arc plate 39; the rubber pad 7 is fixedly connected to the outer wall of the arc plate 39; during operation, when the plate passes through the groove 37 for positioning, the rubber pad 7 increases the friction between the groove 37 and the plate. The above structure can effectively increase the friction between the groove 37 and the plate, reduce slippage when the plate contacts the surface of the groove 37, and keep the plate stable during positioning.

[0030] During operation, the sheet metal is fed into the die 12, where it is elastically positioned by the positioning component 3. The control device moves the punch 13 downwards. Under the combined action of the punch 13 and the die 12, the sheet metal breaks and separates under shearing force. After punching, the workpiece is ejected. During the punching process, the cleaning component 2 blows away and collects the waste generated during the punching process from the middle of the die 12. When the die 12 and punch 13 need to be replaced or reground during use, the control driver 101 is turned on. The output of the driver 101 drives the gear 18 to rotate. When one gear 18 rotates, it drives the other gear 18 to rotate simultaneously through the chain 19, causing the bidirectional lead screw 15 to adjust. When the adjusting groove 14 rotates, it drives the two bidirectional lead screws 15 to move towards both sides of the die 12, causing the fixing block 17 to move out from the middle of the fixing groove 103, thereby quickly removing the die 12. The above operation is repeated when changing the punch 13. During the stamping process of the part, the air pump 25 is turned on. The air pump 25 generates negative pressure airflow that enters the middle of the cleaning pipe 22 through one of the through grooves 23, while the other through groove 23 discharges the airflow. The discharged airflow rushes towards the stamping surface of the die 12, and the waste material is blown away from the surface of the die 12. At the same time, the waste material enters the cleaning pipe 22 along with the negative pressure airflow. The waste material enters the first connecting pipe 24 and is filtered by the filter assembly 4. The filtered airflow then passes through the second connecting pipe 24. The pipe 26 and air pump 25 discharge, thereby achieving waste cleaning. When the plate is sent to the middle of the die 12, the two sides of the plate enter between the two rollers 36, and the two sides of the plate contact the groove 37. As the plate size increases, it applies pressure to the two rollers 36. At this time, the slider 33 slides in the middle of the slide bar 32, the first spring 34 elastically contracts, and at the same time, the damping spring 38 makes the groove 37 elastically press the plate, thereby positioning the plate and maintaining the stability of the plate during stamping. The collection filter box 42 is installed inside the fixed box 41, and the inner side wall of the mounting plate 43 is sleeved on the outer side wall of the fixed box 41. At the same time, the sealing ring 44 seals the mounting plate 43 and the fixed box 41. The buckle 45 and the clip After the seats 46 interlock, the collection filter box 42 is fixed inside the fixed box 41. When the waste material enters the fixed box 41 through the first connecting pipe 24 with the airflow, the waste material enters the collection filter box 42 and is intercepted and collected. The airflow enters the card seat 46 through the collection filter box 42. When installing the concave mold 12 or the convex mold 13, the positioning block 51 is placed in the position corresponding to the positioning groove 5, so that the positioning block 51 enters the positioning groove 5, thereby positioning the concave mold 12 or the convex mold 13. When collecting waste material, the baffle 6 intercepts the waste material in the airflow and effectively collects the waste material. When the plate is positioned by passing through the groove 37, the rubber pad 7 increases the friction between the groove 37 and the plate.
