Description

Technical Field

[0001] The present invention relates to the technical field of stamping equipment, and in particular to a high-precision intelligent stamping device and a stamping process. Background Art

[0002] Stamping is a forming method that uses a press and a die to apply external force to plates, strips, pipes and profiles to produce plastic deformation or separation, thereby obtaining a workpiece (stamping part) of the desired shape and size. Stamping and forging are both plastic processing (or pressure processing), collectively known as forging. The blanks for stamping are mainly hot-rolled and cold-rolled steel plates and strips. Among the steel materials in the world, 60-70% are plates, most of which are made into finished products through stamping.

[0003] High-precision metal sheets are common metal equipment in life. They are widely used in various mechanical parts, metal instruments and products. They are often used as precision parts. When processing high-precision metal sheets, stamping them is one of the common processing processes.

[0004] The Chinese patent discloses "a high-precision sheet metal stamping device", and the publication number is CN111054804A. The invention is convenient for clamping the sheet metal inside the U-shaped clamp seat, and then using the pressing plate to press the top of the sheet metal to improve the fixing effect. After stamping, the metal sheet metal stamped out of the original sheet metal can slide to one side of the movable plate to avoid it falling on the supporting bottom plate to affect the operation, and make the whole device easy to move. However, the existing technology lacks the longitudinal clamping force for clamping the sheet metal, and the metal sheet metal is prone to offset during the stamping process.

[0005] A Chinese patent discloses "a stamping device for processing refrigerator connecting plates with high precision", and the publication number is CN218638298U. The utility model installs a refrigerator connecting plate fixing mechanism, places the refrigerator connecting plate processing workpiece between the clamps, rotates the rotating disk to drive the threaded rod to rotate, and the movable clamp slides along the side surface of the limiting retaining wall under the cooperation of the limiting rod, and cooperates with the fixed clamp to enable the clamp to clamp the processing workpiece. Although the prior art increases the longitudinal clamping force while clamping horizontally, it lacks a front and rear limiting structure for the workpiece. The workpiece is easily translated forward and backward under the action of pressure during the processing, resulting in a displacement of the stamping position, resulting in a reduction in stamping accuracy, and the stamped workpiece cannot meet industrial needs, resulting in defective products. In view of this, we propose a high-precision intelligent stamping device and stamping process. Summary of the invention

[0006] 1. Technical issues to be resolved

[0007] In view of the deficiencies in the prior art, the present invention provides a high-precision intelligent stamping device and a stamping process, which solve the problems raised in the above-mentioned background technology.

[0008] (II) Technical solution

[0009] To achieve the above object, the present invention provides the following technical solutions: A high-precision intelligent stamping device includes a base, two sets of fixing devices are symmetrically arranged on both sides of the top surface of the base, and the processed workpiece is clamped and fixed in three axes to ensure that the workpiece remains stable during the stamping process and the processing accuracy of the workpiece is guaranteed. Two support plates are respectively fixedly connected to both sides of the top surface of the base, and a positioning device is arranged on the two support plates to adjust the position of the workpiece and the stamping equipment so that the stamping equipment is aligned with the part to be stamped of the workpiece to facilitate the stamping work. The stamping device is arranged on the positioning device to perform stamping processing on the workpiece, and spray cooling is performed during the stamping process to protect the equipment and improve the stamping success rate.

[0010] Preferably, the fixing device includes a slide plate, an elastic telescopic rod, a pressure platform, a fixing plate, a threaded rod, a clamping plate, and a turntable. The slide plate is slidably connected to the top surface of the base, one end of the elastic telescopic rod is fixedly connected to one side of the support plate, and the other end of the elastic telescopic rod is rotatably connected to the slide plate through a bearing. The pressure platform is fixedly connected to the side of the slide plate away from the support plate, and the pressure platform is slidably connected to the top surface of the base, the fixing plate is fixedly connected above the side of the slide plate away from the support plate, the threaded rod passes through the fixing plate and is threadedly connected to the fixing plate, the clamping plate is fixedly connected to the bottom end of the threaded rod, and the clamping plate fits with the slide plate. This arrangement ensures that the threaded rod During the rotation and lifting of the rod, the clamping plate will not rotate with the threaded rod and can only be lifted vertically. The turntable is fixedly connected to the top of the threaded rod. The fixing device also includes a storage chamber, a slider, a spring 1, and a baffle. The storage chamber is opened in the pressure platform. The slider is slidably connected in the storage chamber. One end of the spring 1 is fixedly connected to the bottom surface of the slider, and the other end of the spring 1 is fixedly connected to the bottom surface of the storage chamber. The baffle is fixedly connected to the top surface of the slider. The baffle passes through the top surface of the pressure platform and is slidably connected to the pressure platform. Each of the pressure platforms is provided with multiple groups of sliders, springs, and baffles, and each group of sliders, springs, and baffles are independently arranged at equal intervals.

[0011] Preferably, the positioning device includes a mounting plate, a driving motor, a rotating rod, a driving wheel, a rotating shaft, a driven wheel, a top plate, and a mounting frame. The mounting plate is fixedly connected to one side of the support plate, the driving motor is fixedly installed on the top surface of the mounting plate, one end of the rotating rod is fixedly connected to the output end of the driving motor through a coupling, the other end of the rotating rod is fixedly connected to the driving wheel, the rotating shaft passes through the support plate and is rotatably connected to the support plate through a bearing, the driven wheel is fixedly connected to one end of the rotating shaft, the driven wheel is meshed with the driving wheel, and the diameter of the driven wheel is larger than the radius of the driving wheel. This arrangement can slow down the rotation of the driven wheel. The rotation speed of the driving wheel and the rotating shaft reduces the horizontal sliding speed of the mounting frame, which facilitates lateral alignment and makes the alignment work easier. The top plate is fixedly connected between the two support plates, and the mounting frame is slidably connected to the top plate. The middle section of the rotating shaft is provided with a thread, and the rotating shaft passes through the mounting frame and is threadedly connected to the mounting frame. The positioning device also includes an LED lamp, a telescopic belt, a hook, and a laser lamp. The LED lamp is fixedly installed at the center of the bottom surface of the top plate, and the telescopic belt and the hook are respectively fixedly installed on one side close to the two fixed plates, and the laser lamp is arranged on the stamping device.

[0012] Preferably, the punching device includes a cylinder, a mounting plate, a buffer groove, a punching head, and a second spring. The cylinder is fixedly mounted on a mounting frame, the mounting plate is fixedly mounted on a movable end of the cylinder, the laser lamps are fixedly mounted on the circumference of the bottom surface of the mounting plate at equal intervals, the buffer groove is fixedly connected to the center of the bottom surface of the mounting plate, the punching head is slidably connected in the buffer groove, one end of the second spring is fixedly connected to the top surface of the inner wall of the buffer groove, and the other end of the buffer groove is fixedly connected to the top surface of the punching head. The punching device also includes a pump cylinder, a vent pipe, a water inlet pipe, a water tank, a drain pipe, an inclined plate, and a spray head. The pump cylinder is fixedly connected to the bottom surface of the mounting plate, and the vent pipe runs through the buffer groove and the pump cylinder And it is fixedly connected to the buffer tank and the pump pressure cylinder, the ventilation pipe connects the buffer tank with the pump pressure cylinder, the water inlet pipe passes through the mounting plate and is fixedly connected to the mounting plate, the water tank is fixedly installed on the top surface of the mounting plate, and the water tank is connected to the pump pressure cylinder through the water inlet pipe, the water tank is annularly arranged and the inner diameter of the water tank is larger than the maximum diameter of the cylinder. This arrangement ensures that the water tank will not block the contraction of the cylinder during the process of the cylinder driving the mounting plate to rise, thereby ensuring the normal operation of the device, the drain pipe passes through the bottom surface of the pump pressure cylinder and is fixedly connected to the pump pressure cylinder, the inclined plate is fixedly connected to the outer wall of one side of the buffer tank, the spray head is fixedly installed on the bottom surface of the inclined plate, and the spray head is connected to the pump pressure cylinder through the drain pipe.

[0013] Preferably, the connection portion between one side of the baffle and the top surface is set as a smooth arc surface. By setting the smooth arc surface, the baffle can be squeezed by the workpiece to retract into the storage cavity during the workpiece installation process, without manually pressing the baffle, thereby simplifying the operation steps. When the spring 1 is in a natural state, the height of the baffle extending out of the pressure platform is less than the maximum compression length of the spring 1, and the difference between the length of the threaded rod and the thickness of the fixed plate is greater than the length of the baffle. This arrangement ensures that the clamping plate can be lowered to fit the top surface of the pressure platform, and the baffle under the workpiece is completely pressed into the storage cavity, thereby longitudinally clamping the workpiece through the clamping plate and the pressure platform.

[0014] Preferably, the fixing device also includes a rubber pad, which is bonded to the top surface of the pressure platform and the bottom surface of the pressure plate. The surfaces close to the rubber pads on the pressure platform and the pressure plate are roughened. By providing the rubber pad, it is possible to avoid rigid contact between the pressure plate and the pressure platform and the workpiece to protect the workpiece, and to utilize the high friction coefficient of rubber to increase the friction between the workpiece and the pressure plate and the pressure platform, thereby enhancing the fixing effect on the workpiece.

[0015] Preferably, limiting slide grooves are provided on both sides of the top plate, and the two ends of the mounting frame are respectively clamped and slidably connected in the two limiting slide grooves. By setting the limiting slide grooves, the gravity of the mounting frame and all the equipment thereon can be applied to the top plate, thereby preventing gravity from acting on the rotating shaft, bending the rotating shaft, affecting the threaded engagement of the rotating shaft and the mounting frame, and further affecting the translation ability of the mounting frame.

[0016] Preferably, the projections of the punching head and the telescopic belt on the base coincide with each other, and the telescopic belt is arranged directly below the LED lamp. This arrangement ensures that the shadow created by the telescopic belt on the base is the horizontal movement path of the punching head, so that when the workpiece is fixed, the punching part of the workpiece can coincide with the shadow, thereby realizing the longitudinal positioning of the workpiece.

[0017] Preferably, a one-way valve 1 is fixedly installed in the water inlet pipe for one-way connection from the water tank to the pump cylinder, and a one-way valve 2 is fixedly installed in the drain pipe for one-way connection from the pump cylinder to the spray head. By arranging the one-way valve 1 and the two-way valve, the coolant can only flow from the water tank to the pump cylinder to the spray head in one direction, and spraying and cooling can be automatically performed when the air pressure inside the buffer tank changes. The stamping device also includes a foam plate, a push rod, and a rubber sheet. The foam plate is slidably connected to the pump cylinder, and water leakage holes are evenly opened on the foam plate. The push rod is fixedly connected to the top surface of the foam plate, and the rubber sheet is fixedly connected to the top of the push rod, and the radius of the rubber sheet is larger than the inner diameter of the water inlet pipe. By arranging the foam plate, the push rod, and the rubber sheet, it is ensured that after the coolant is injected into the pump cylinder, the coolant floats the foam plate, so that the rubber sheet blocks the water inlet pipe and stops water inlet, thereby preventing the coolant from continuously leaking when the stamping work is not performed, causing waste.

[0018] A stamping process comprises the following steps: S0: Equipment debugging, specifically: A1: Assemble the entire device and place it stably on the processing platform; A2: Debug the performance of the drive motor and cylinder to ensure that the drive motor can drive the mounting frame to slide horizontally, the cylinder can drive the mounting plate to rise and fall vertically, and the drive motor can make the mounting frame be located at the end of the shaft thread, and the cylinder can be limited to shrink so that the mounting plate is at the highest point of the stroke; A3: Inject coolant into the water tank, press the punch head upward once to expel the air in the pump cylinder and press in the coolant; S1: Fix the workpiece, specifically: B1: Insert the workpiece horizontally between the two slides. The workpiece presses the arc surface of the baffle to make the baffle part retract into the storage cavity. The workpiece is initially fixed by the elastic force of a pair of slides and the baffle; B2: Pull out the telescopic belt and hang one end of the telescopic belt on the hook, turn on the LED light to illuminate the telescopic belt, and continue to push the workpiece inward until the pre-punching part on the workpiece coincides with the shadow part of the telescopic belt; B3: Rotate the turntable to make the threaded rod rotate and descend, driving the clamping plate to descend and squeeze the workpiece until the clamping plate clamps and fixes the workpiece on the top surface of the pressure platform. The clamping plate is used to fix the workpiece longitudinally, and the baffle is used to fix the front and rear sides of the workpiece. B4: Rotate the movable end of the elastic telescopic rod to make the inner and outer tubes of the elastic telescopic rod rotate relative to each other, and the movable eccentric sleeve squeezes the inner wall of the outer tube to achieve locking, that is, to achieve lateral fixation of the workpiece; S2: Adjust the alignment, specifically: C1: Turn on the laser light to make it emit laser light onto the telescopic belt, remove the telescopic belt from the hook, and retract the telescopic belt into the fixed plate driven by the clockwork spring; C2: Start the drive motor, which drives the rotating rod to rotate, and the rotating shaft rotates through the driving wheel and the driven wheel, thereby driving the mounting frame to slide horizontally along the top plate; C3: Observe the light spot irradiated by the laser light on the workpiece. When the light spot irradiates the workpiece at the position to be processed, turn off the drive motor to fix the position of the mounting frame to complete the alignment and positioning. S3: stamping process, specifically: D1: Start the cylinder, the movable end of the cylinder extends to drive the mounting plate to descend vertically, and the mounting plate drives the buffer groove and the punch head to descend vertically until the punch head contacts the top surface of the workpiece; D2: After the punch head contacts the top surface of the workpiece, the cylinder continues to extend to make the punch head punch the workpiece. At the same time, the reaction force of the workpiece on the punch head makes the punch head slide into the buffer groove, causing the second spring to contract and press the air in the buffer groove into the pump cylinder. The coolant in the pump cylinder is pressurized into the spray head through the drain pipe, and then sprayed on the punching part in atomization to cool it down. D3: When the second spring is compressed to the limit, the punch head cannot continue to shrink. At this time, the punch head rigidly squeezes the workpiece to achieve the purpose of punching; D4: After the workpiece is stamped, the cylinder is controlled to contract, causing the mounting plate to rise. The elastic force generated by the second deformation of the spring pushes the punch head out of the buffer groove. At this time, the internal space of the punch head increases, generating negative pressure, sucking the air in the pump cylinder into the punch head, and sucking the coolant in the water tank into the pump cylinder for standby use. The mounting plate rises to the highest point of the stroke, and the cylinder is closed to fix the position of the mounting plate; S4: Workpiece disassembly, specifically: E1: Cool the workpiece naturally (artificial accelerated cooling can be performed if conditions permit) until the temperature of the stamping part of the workpiece returns to ambient temperature; E2: After cooling is completed, turn the movable rod of the elastic telescopic rod to make the elastic telescopic rod contact and lock, rotate the turntable in the opposite direction to make the pressing plate rise until it contacts the fixed plate, push the two slides apart, and remove the workpiece from the fixing device; S5: Subsequent processing, specifically: F1: Repeat steps S1 to S4 to stamp the next set of workpieces. During the stamping process, add coolant to the water tank as needed; F2: After all workpieces are stamped, clean the stamping debris on the base and fixture, drain the coolant in the water tank and clean and dry the water tank; F3: After cleaning the device, store the entire device in a cool and dry place.

[0019] (III) Beneficial effects

[0020] Compared with the prior art, the present invention provides a high-precision intelligent stamping device and stamping process, which has the following beneficial effects:

[0021] 1. The present invention sets a fixing device, utilizes two elastic telescopic rods to push the slide plate to move close to each other, applies lateral pressure to the workpiece, so that the workpiece is fixed laterally, utilizes a fixing plate to press the workpiece against the pressure platform, so that the workpiece is fixed longitudinally, utilizes a baffle to limit the front and rear sides of the workpiece, so that the workpiece is fixed front and back, and the three-axis fixation cooperates to stably clamp and fix the workpiece, thereby ensuring that the workpiece remains stable during the stamping process and ensuring the processing accuracy of the workpiece.

[0022] 2. The present invention sets a positioning device. During the process of fixing the workpiece, the LED light is used to illuminate the telescopic belt, so that the shadow of the telescopic belt projected on the workpiece coincides with the part to be punched on the workpiece, thereby realizing longitudinal positioning. The driving motor is used to drive the active wheel to rotate, so that the two driven wheels drive the two rotating shafts to rotate synchronously in the same direction, so that the mounting frame can be translated stably. The laser light is used to align with the part to be punched on the workpiece, so that the lateral positioning can be realized, and the punching device is located directly above the part to be punched on the workpiece, so as to ensure the punching accuracy.

[0023] 3. The present invention sets a punching device and uses a cylinder to push the mounting plate downward, so that the punching head descends to punch the workpiece, and during the punching process, the punching head shrinks toward the buffer groove for buffering, and at the same time, the gas in the buffer groove is pressed into the pump cylinder, so that the coolant in the pump cylinder is sprayed out from the spray head to cool the punching head and the workpiece, and after the punching is completed, the punching head is reset by the second elastic force of the spring, and the negative pressure in the buffer groove is used to suck the coolant in the water tank into the pump cylinder for standby use.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] Embodiment 1

[0028] See also Figure 1-9 As shown, a technical solution provided by the present invention is: A high-precision intelligent stamping device includes a base 1, two sets of fixing devices 2 are symmetrically arranged on both sides of the top surface of the base 1, and the workpiece to be processed is clamped and fixed in three axes to ensure that the workpiece remains stable during the stamping process and the processing accuracy of the workpiece is guaranteed. Two support plates 3 are respectively fixedly connected to both sides of the top surface of the base 1, and a positioning device 4 is arranged on the two support plates 3 to adjust the position of the workpiece and the stamping equipment so that the stamping equipment is aligned with the part to be stamped of the workpiece to facilitate the stamping work. The stamping device 5 is arranged on the positioning device 4 to perform stamping processing on the workpiece, and spray cooling is performed during the stamping process to protect the equipment and improve the stamping success rate.

[0029] Furthermore, the fixing device 2 includes a slide plate 201, an elastic telescopic rod 202, a pressure platform 203, a fixed plate 208, a threaded rod 209, a clamping plate 210, and a turntable 211. The slide plate 201 is slidably connected to the top surface of the base 1, one end of the elastic telescopic rod 202 is fixedly connected to one side of the support plate 3, and the other end of the elastic telescopic rod 202 is rotatably connected to the slide plate 201 through a bearing. The pressure platform 203 is fixedly connected to the side of the slide plate 201 away from the support plate 3, and the pressure platform 203 is slidably connected to the top surface of the base 1, the fixed plate 208 is fixedly connected above the side of the slide plate 201 away from the support plate 3, the threaded rod 209 penetrates the fixed plate 208 and is threadedly connected to the fixed plate 208, the clamping plate 210 is fixedly connected to the bottom end of the threaded rod 209, and the clamping plate 210 is fixedly connected to the bottom end of the threaded rod 209, and the clamping plate 210 is fixedly connected to the bottom end of the threaded rod 209. The plate 210 fits with the slide plate 201. This arrangement ensures that during the rotation and lifting of the threaded rod 209, the clamping plate 210 will not rotate with the threaded rod 209 and can only be lifted vertically. The turntable 211 is fixedly connected to the top of the threaded rod 209. The fixing device 2 also includes a rubber pad 212. The rubber pad 212 is bonded to the top surface of the pressure platform 203 and the bottom surface of the clamping plate 210. The surfaces of the rubber pads 212 on the pressure platform 203 and the clamping plate 210 are rough. By setting the rubber pad 212, it is possible to avoid rigid contact between the clamping plate 210 and the pressure platform 203 and the workpiece, thereby protecting the workpiece, and utilize the high friction coefficient of rubber to increase the friction between the workpiece and the clamping plate 210 and the pressure platform 203, thereby enhancing the fixing effect on the workpiece.

[0030] Furthermore, the fixing device 2 also includes a storage cavity 204, a slider 205, a spring 206, and a baffle 207. The storage cavity 204 is opened in the pressure platform 203, the slider 205 is slidably connected in the storage cavity 204, one end of the spring 206 is fixedly connected to the bottom surface of the slider 205, and the other end of the spring 206 is fixedly connected to the bottom surface of the storage cavity 204. The baffle 207 is fixedly connected to the top surface of the slider 205, and the baffle 207 passes through the top surface of the pressure platform 203 and is slidably connected to the pressure platform 203. Each pressure platform 203 is provided with multiple groups of sliders 205, springs 206, and baffles 207. Each group of sliders 205, springs 206, and baffles 207 are independently arranged at equal intervals. The baffle 207 The connection part between one side and the top surface is set as a smooth arc surface. By setting the smooth arc surface, during the workpiece installation process, the baffle 207 can be squeezed by the workpiece to retract into the storage chamber 204 without manually pressing the baffle 207, thereby simplifying the operation steps. When the spring 1 206 is in a natural state, the baffle 207 extends out of the pressure platform 203 to a height that is less than the maximum compression length of the spring 1 206, and the difference between the length of the threaded rod 209 and the thickness of the fixed plate 208 is greater than the length of the baffle 207. This arrangement ensures that the clamping plate 210 can descend to fit the top surface of the pressure platform 203, and the baffle 207 under the workpiece is completely pressed into the storage chamber 204, thereby longitudinally clamping the workpiece through the clamping plate 210 and the pressure platform 203.

[0031] In addition, the positioning device 4 includes a mounting plate 401, a drive motor 402, a rotating rod 403, a driving wheel 404, a rotating shaft 405, a driven wheel 406, a top plate 407, and a mounting frame 408.

The rotating shaft 405 passes through the support plate 3 and is rotatably connected to the support plate 3 through a bearing. The driven wheel 406 is fixedly connected to one end of the rotating shaft 405, and the driven wheel 406 is meshed with the driving wheel 404. The diameter of the driven wheel 406 is larger than the radius of the driving wheel 404. This arrangement can slow down the rotation speed of the driven wheel 406 and the rotating shaft 405 , thereby reducing the horizontal sliding speed of the mounting frame 408, facilitating lateral alignment, and making the alignment work easier.

Limiting slots are provided on both sides of the top plate 407, and the two ends of the mounting frame 408 are respectively clamped and slidably connected to the two limiting slots. By setting the limiting slots, the gravity of the mounting frame 408 and all the equipment thereon can be applied to the top plate 407, avoiding gravity acting on the rotating shaft 405, bending the rotating shaft 405, affecting the threaded meshing of the rotating shaft 405 and the mounting frame 408, and thus affecting the translation ability of the mounting frame 408.

[0032] In addition, the positioning device 4 also includes an LED lamp 409, a telescopic belt 410, a hook 411, and a laser lamp 412. The LED lamp 409 is fixedly installed at the center of the bottom surface of the top plate 407, the telescopic belt 410 and the hook 411 are respectively fixedly installed on the side close to the two fixed plates 208, and the laser lamp 412 is arranged on the stamping device 5. The projection of the stamping head 504 and the telescopic belt 410 on the base 1 coincide with each other, and the telescopic belt 410 is arranged directly below the LED lamp 409. This arrangement ensures that the shadow produced by the telescopic belt 410 on the base 1 is the horizontal movement path of the stamping head 504, so that when the workpiece is fixed, the stamping part of the workpiece can coincide with the shadow, thereby realizing the longitudinal positioning of the workpiece.

[0033] It is worth noting that the punching device 5 includes a cylinder 501, a mounting plate 502, a buffer groove 503, a punching head 504, and a second spring 505. The cylinder 501 is fixedly mounted on the mounting frame 408, the mounting plate 502 is fixedly mounted on the movable end of the cylinder 501, the laser lamps 412 are fixedly mounted at equal intervals on the circumference of the bottom surface of the mounting plate 502, the buffer groove 503 is fixedly connected to the center of the bottom surface of the mounting plate 502, the punching head 504 is slidably connected in the buffer groove 503, one end of the second spring 505 is fixedly connected to the top surface of the inner wall of the buffer groove 503, and the other end of the buffer groove 503 is fixedly connected to the top surface of the punching head 504.

The vent pipe 507 connects the buffer groove 503 with the pump cylinder 506. The water inlet pipe 508 passes through the mounting plate 502 and is fixedly connected to the mounting plate 502. The water tank 509 is fixedly installed on the top surface of the mounting plate 502, and the water tank 509 is connected to the pump cylinder 506 through the water inlet pipe 508. The water tank 509 is annularly arranged and the inner diameter of the water tank 509 is larger than the maximum diameter of the cylinder 501. This arrangement ensures that the cylinder 501 drives the mounting plate 5 During the rising process of 02, the water tank 509 will not block the contraction of the cylinder 501, ensuring the normal operation of the device, the drain pipe 510 passes through the bottom surface of the pump cylinder 506 and is fixedly connected to the pump cylinder 506, the inclined plate 511 is fixedly connected to the outer wall of one side of the buffer tank 503, the spray head 512 is fixedly installed on the bottom surface of the inclined plate 511, and the spray head 512 is connected to the pump cylinder 506 through the drain pipe 510. A one-way valve 1 is fixedly installed in the water inlet pipe 508, which is connected from the water tank 509 to the pump cylinder 506 in one way, and a one-way valve 2 is fixedly installed in the drain pipe 510, which is connected from the pump cylinder 506 to the spray head 512 in one way. By setting the one-way valve 1 and the one-way valve 2, the coolant can only flow from the water tank 509 to the pump cylinder 506 to the spray head 512 in one way, and when the air pressure inside the buffer tank 503 changes, spray cooling can be automatically performed.

[0035] It should be added that the stamping device 5 also includes a foam plate 513, a push rod 514, and a rubber sheet 515. The foam plate 513 is slidably connected in the pump cylinder 506, and water leakage holes are evenly opened on the foam plate 513. The push rod 514 is fixedly connected to the top surface of the foam plate 513, and the rubber sheet 515 is fixedly connected to the top of the push rod 514, and the radius of the rubber sheet 515 is larger than the inner diameter of the water inlet pipe 508. By arranging the foam plate 513, the push rod 514, and the rubber sheet 515, it is ensured that after the coolant is injected into the pump cylinder 506, the coolant makes the foam plate 513 float, so that the rubber sheet 515 blocks the water inlet pipe 508 and stops the water supply, thereby preventing the coolant from continuously leaking when the stamping work is not carried out, causing waste.

[0036] A stamping process comprises the following steps: S0: Equipment debugging, specifically: A1: Assemble the entire device and place it stably on the processing platform; A2: Debug the performance of the drive motor 402 and the cylinder 501 to ensure that the drive motor 402 can drive the mounting frame 408 to slide horizontally, and the cylinder 501 can drive the mounting plate 502 to rise and fall vertically, and the drive motor 402 can make the mounting frame 408 be located at the threaded end of the rotating shaft 405, and the cylinder 501 can be maximally contracted to make the mounting plate 502 be located at the highest point of the stroke; A3: Inject coolant into the water tank 509, press the punch head 504 upward once to expel the air in the pump cylinder 506 and press in the coolant; S1: Fix the workpiece, specifically: B1: Insert the workpiece horizontally between the two slide plates 201, and the workpiece presses the arc surface of the baffle 207 so that the baffle 207 is partially retracted into the receiving cavity 204, and the workpiece is initially fixed by the elastic force of the spring 1 206 on the slider 205 and the baffle 207; B2: Pull out the telescopic belt 410 so that one end of the telescopic belt 410 is hung on the hook 411, turn on the LED light 409 to illuminate the telescopic belt 410, and continue to push the workpiece inward until the pre-punching part on the workpiece coincides with the shadow part of the telescopic belt 410; B3: The turntable 211 is rotated to rotate and lower the threaded rod 209, driving the pressing plate 210 to lower and squeeze the workpiece until the pressing plate 210 presses and fixes the workpiece on the top surface of the pressure platform 203. The workpiece is longitudinally fixed by the pressing plate 210, and the front and rear sides of the workpiece are fixed by the baffle 207. B4: Rotate the movable end of the elastic telescopic rod 202 to make the inner and outer tubes of the elastic telescopic rod 202 rotate relative to each other, and the movable eccentric sleeve squeezes the inner wall of the outer tube, thereby achieving locking, that is, achieving lateral fixation of the workpiece; S2: Adjust the alignment, specifically: C1: Turn on the laser lamp 412 to emit laser light onto the telescopic belt 410, remove the telescopic belt 410 from the hook 411, and retract the telescopic belt 410 into the fixed plate 208 driven by the clockwork spring; C2: Start the driving motor 402, which drives the rotating rod 403 to rotate, and the rotating shaft 405 rotates through the driving wheel 404 and the driven wheel 406, thereby driving the mounting frame 408 to slide horizontally along the top plate 407; C3: Observe the light spot irradiated by the laser lamp 412 on the workpiece. When the light spot irradiates the position to be processed on the workpiece, turn off the drive motor 402 to fix the position of the mounting frame 408 to complete the alignment and positioning; S3: stamping process, specifically: D1: Start the cylinder 501, the movable end of the cylinder 501 extends to drive the mounting plate 502 to vertically descend, and the mounting plate 502 drives the buffer groove 503 and the punch head 504 to vertically descend until the punch head 504 contacts the top surface of the workpiece; D2: After the punch head 504 contacts the top surface of the workpiece, the cylinder 501 continues to extend so that the punch head 504 punches the workpiece. At the same time, the reaction force of the workpiece on the punch head 504 causes the punch head 504 to slide into the buffer groove 503, so that the spring 2 505 contracts and the air in the buffer groove 503 is pressed into the pump cylinder 506, so that the coolant in the pump cylinder 506 is pressurized to enter the spray head 512 through the drain pipe 510, and then enters the spray head 512 to be atomized and sprayed on the punching part to cool it down. D3: When the second spring 505 is compressed to the limit, the punch head 504 cannot continue to shrink. At this time, the punch head 504 rigidly squeezes the workpiece to achieve the purpose of punching; D4: After the workpiece is stamped, the cylinder 501 is controlled to contract, so that the mounting plate 502 rises. The elastic force generated by the deformation of the spring 2 505 pushes the punch head 504 out of the buffer groove 503. At this time, the internal space of the punch head 504 increases, generating negative pressure, sucking the air in the pump cylinder 506 into the punch head 504, and sucking the coolant in the water tank 509 into the pump cylinder 506 for standby use. The mounting plate 502 rises to the highest point of the stroke, and the cylinder 501 is closed to fix the position of the mounting plate 502; S4: Workpiece disassembly, specifically: E1: Cool the workpiece naturally (artificial accelerated cooling can be performed if conditions permit) until the temperature of the stamping part of the workpiece returns to ambient temperature; E2: After the cooling is completed, the movable rod of the elastic telescopic rod 202 is rotated to make the elastic telescopic rod 202 contact and lock, and the turntable 211 is rotated in the opposite direction to make the pressing plate 210 rise to contact with the fixed plate 208, and the two slide plates 201 are pushed apart to remove the workpiece from the fixing device 2; S5: Subsequent processing, specifically: F1: Repeat steps S1 to S4 to perform stamping of the next set of workpieces, and add coolant to the water tank 509 as needed during the stamping process; F2: After all workpieces are stamped, the stamping debris on the base 1 and the fixture 2 are cleaned, the coolant in the water tank 509 is drained, and the water tank 509 is cleaned and dried; F3: After cleaning the device, store the entire device in a cool and dry place.

Specifically, the eccentric principle is utilized to fix the eccentric device to one end of the inner tube inserted into the outer tube. A movable eccentric sleeve is sleeved on the eccentric column. The inner and outer tubes are rotated relative to each other, and the movable eccentric sleeve squeezes the inner wall of the outer tube to achieve locking.

The above are all existing technologies and can be easily implemented by those skilled in the art.

[0040] To sum up, when the high-precision intelligent stamping device and stamping process are used, the device is assembled as a whole and placed stably on the processing platform, and the performance of the drive motor 402 and the cylinder 501 is debugged to ensure that the drive motor 402 can drive the mounting frame 408 to slide horizontally, and the cylinder 501 can drive the mounting plate 502 to rise and fall vertically. The mounting frame 408 is located at the threaded end of the rotating shaft 405 through the drive motor 402, and the mounting plate 502 is located at the highest point of the stroke through the extreme contraction of the cylinder 501, and coolant is injected into the water tank 509. The punch head 504 is pressed upward once to expel the air in the pump cylinder 506 and press the coolant in.

[0041] The workpiece is horizontally inserted between the two slides 201, and the workpiece squeezes the arc surface of the baffle 207 so that the baffle 207 partially retracts into the storage chamber 204. The workpiece is initially fixed by the elastic force of the slider 205 and the baffle 207 by using the spring 1 206. The telescopic belt 410 is pulled out and one end of the telescopic belt 410 is hung on the hook 411. The LED light 409 is turned on to illuminate the telescopic belt 410, and the workpiece is continuously pushed inward until the pre-punched part on the workpiece coincides with the shadow part of the telescopic belt 410. The turntable 211 is rotated to rotate and descend the threaded rod 209, driving the clamping plate 210 to descend and squeeze the workpiece until the clamping plate 210 clamps and fixes the workpiece on the top surface of the pressure platform 203. The clamping plate 210 is used to longitudinally fix the workpiece, and the baffle 207 is used to fix the front and rear sides of the workpiece. The movable end of the elastic telescopic rod 202 is rotated to make the inner and outer tubes of the elastic telescopic rod 202 rotate relative to each other, and the movable eccentric sleeve squeezes the inner wall of the outer tube, thereby achieving locking, that is, achieving the lateral fixation of the workpiece.

[0042] Turn on the laser lamp 412, so that the laser lamp 412 emits laser to illuminate the telescopic belt 410, remove the telescopic belt 410 from the hook 411, and retract the telescopic belt 410 into the fixed plate 208 driven by the clockwork spring, start the drive motor 402, and the drive motor 402 drives the rotating rod 403 to rotate, and the rotating shaft 405 is rotated through the driving wheel 404 and the driven wheel 406, thereby driving the mounting frame 408 to slide horizontally along the top plate 407, and observe the light spot irradiated by the laser lamp 412 on the workpiece. When the light spot is irradiated on the position to be processed of the workpiece, turn off the drive motor 402 to fix the position of the mounting frame 408 to complete the alignment and positioning.

[0043] Start the cylinder 501, the movable end of the cylinder 501 extends to drive the mounting plate 502 to descend vertically, and the mounting plate 502 drives the buffer groove 503 and the punch head 504 to descend vertically until the punch head 504 contacts the top surface of the workpiece. After the punch head 504 contacts the top surface of the workpiece, the cylinder 501 continues to extend to make the punch head 504 punch the workpiece. At the same time, the reaction force of the workpiece on the punch head 504 makes the punch head 504 slide into the buffer groove 503, so that the spring 505 contracts and the air in the buffer groove 503 is pressed into the pump cylinder 506, so that the coolant in the pump cylinder 506 is pressurized into the spray head 512 through the drain pipe 510 and is atomized by the spray head 512 Spray on the stamping part to cool it down. When the second spring 505 is compressed to the limit, the punch head 504 cannot continue to shrink. At this time, the punch head 504 rigidly extrude the workpiece to achieve the stamping purpose. After the workpiece is stamped and formed, the cylinder 501 is controlled to shrink to make the mounting plate 502 rise. The elastic force generated by the deformation of the second spring 505 pushes the punch head 504 out of the buffer groove 503. At this time, the internal space of the punch head 504 increases to generate negative pressure, sucking the air in the pump cylinder 506 into the punch head 504, and sucking the coolant in the water tank 509 into the pump cylinder 506 for standby use. The mounting plate 502 rises to the highest point of the stroke and the cylinder 501 is closed to fix the position of the mounting plate 502.

[0044] Cool naturally until the temperature of the stamping part of the workpiece returns to the ambient temperature. After cooling is completed, turn the movable rod of the elastic telescopic rod 202 to make the elastic telescopic rod 202 contact and lock, reversely rotate the turntable 211 to make the clamping plate 210 rise until it contacts with the fixed plate 208, push the two slides 201 apart, and remove the workpiece from the fixing device 2. After all workpieces are stamped, clean the stamping debris on the base 1 and the fixing device 2, drain the coolant in the water tank 509 and clean and dry the water tank 509. After the device is cleaned, store the entire device in a cool and dry place.
