Description

Technical Field

[0001] The present invention relates to the field of stamping technology, in particular to a high-speed stamping device. Background Art

[0002] Stamping is a forming method that relies on a drive mechanism and a mold (including an upper mold and a lower mold) to apply external force to plates, strips, pipes, and profiles to cause them to undergo plastic deformation or separation, thereby obtaining a workpiece (stamping part) of the desired shape and size. The high-speed stamping machine in the prior art can quickly stamp out steel strip raw materials, specifically by using the upper mold to impact and squeeze the steel strip placed on the lower mold at high speed to form the parts. For example, a high-speed stamping machine that can be automatically oiled is disclosed in a Chinese patent with patent publication number CN 116441438 A, which can realize automatic oiling to detect blockage in the nozzle pipeline of the high-speed stamping machine.

[0003] However, the existing high-speed stamping equipment has the following problems when using steel strip raw materials for stamping: each stamping will produce scraps, and the scraps left on the surface of the lower die may affect the subsequent stamping work. Therefore, workers are required to clean and collect the waste regularly, which affects the processing efficiency and also increases the labor intensity of the workers; the existing high-speed stamping equipment needs to unwind the steel coil to form a steel strip. Since the steel coils have different specifications and sizes, different material dividing devices are required, which is not only costly, but also requires the replacement of the material dividing device each time a different steel coil is placed, which also affects the overall production efficiency; in addition, the positioning holes of the molds used in the existing high-speed stamping equipment are prone to residual debris, which makes it easy for the upper and lower molds of the mold to be misaligned when they are closed, and even jamming occurs, resulting in unstable closing.

[0032] The embodiments of the present invention are described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered below.

[0033] A high-speed stamping equipment, comprising:

[0034] An unwinding assembly 1, the unwinding assembly 1 is used to unwind the steel coil 2 to form a steel strip 3;

[0035] A feeding assembly 4, which is arranged at the rear side of the unwinding assembly 1 and is used to convey the steel strip 3;

[0036] The stamping assembly 5 is arranged at the discharge end of the feeding assembly 4. The stamping assembly 5 includes an upper mold 21, a lower mold 22, a driving mechanism 33 and a cleaning assembly 25. The upper mold 21 is connected to the driving mechanism 33. The driving mechanism 33 is used to drive the upper mold 21 to close the mold relative to the lower mold 22, thereby stamping the steel strip 3 between the upper mold 21 and the lower mold 22; the lower mold 22 is installed and fixed by a base 23, and a collecting groove is opened on the base 23 around the lower mold 22. The cleaning assembly 25 is arranged on the side of the lower mold 22, and the cleaning assembly 25 is used to clean the scraps on the surface of the lower mold 22 into the collecting groove.

[0037] The high-speed stamping equipment of the present invention unwinds the steel coil 2 to form a steel strip 3 through the unwinding component 1, and then continuously feeds the steel strip 3 forward into the stamping component 5 through the feeding component 4. The stamping component 5 drives the upper mold 21 and the lower mold 22 to close the mold and stamp through the driving mechanism 33, so as to realize rapid stamping and forming of parts products, and a cleaning component 25 is arranged above the lower mold 22, and the cleaning component 25 can be used to clean the scraps left on the surface of the lower mold 22 after the steel strip 3 is stamped. While the lower mold 22 is installed and fixed by the base 23, a collecting groove is opened on the base 23 around the lower mold 22, and the scraps cleaned from the surface of the lower mold 22 by the cleaning component 25 are collected by the collecting groove, so that the scraps remaining on the surface of the lower mold 22 can be cleaned in time to avoid affecting the subsequent stamping process.

[0038] Preferably, please refer to Figure 6 and Figure 7 As shown, the cleaning assembly 25 includes a scraper 26 and a pushing motor 28. The scraper 26 is arranged on one side of the lower mold 22. The pushing motor 28 is connected to the scraper 26. The pushing motor 28 is used to drive the scraper 26 to move to the upper surface of the lower mold 22 and reciprocate along the upper surface of the lower mold 22, thereby scraping off the scrap corners on the upper surface of the lower mold 22 through the scraper 26.

[0039] It can be understood that the pushing motor 28 drives the pushing member 27 to move, and then the pushing member 27 drives the scraping member 26 to reciprocate to scrape off the scraps left on the surface of the lower mold 22. This not only can timely and efficiently clean the scraps on the surface of the lower mold 22, but also can save the work of manual operation to scrape off the scraps, effectively reducing the labor intensity of workers.

[0040] Preferably, please refer to Figure 6 and Figure 7 As shown, the cleaning component 25 also includes a pushing piece 27. The output shaft of the pushing motor 28 is connected to the screw rod 30. The pushing piece 27 is sleeved on the screw rod 30 and is connected to the screw rod 30 by a thread. The collecting trough includes a first collecting trough 29 located on one side of the discharge end of the lower mold 22. Discharge ports are opened at both ends of the first collecting trough 29. The pushing piece 27 is located in the first collecting trough 29. The pushing motor 28 is also used to drive the pushing piece 27 to reciprocate along the first collecting trough 29 and push the scraps in the first collecting trough 29 to the discharge port. The scraper 26 is arranged on the pushing piece 27 and extends to the feed end of the lower mold 22.

[0041] It can be understood that the screw rod 30 is arranged in the first collecting groove 29, and the screw rod 30 and the pushing piece 27 are matched through threads, and the pushing piece 27 is located in the first collecting groove 29 and is limited and guided by the first collecting groove 29. Therefore, when the pushing motor 28 drives the screw rod 30 to rotate, the screw rod 30 can drive the pushing piece 27 to move along the length direction of the first collecting groove 29, and then the waste in the first collecting groove 29 is pushed to the discharge port through the pushing piece 27, so as to avoid the accumulation of leftover waste in the first collecting groove 29, thereby achieving the effect of timely cleaning.

[0042] Preferably, the scraper 26 and the first collecting trough 29 are arranged at an angle, and brushes are arranged at the bottom ends of the scraper 26 and the pusher 27, and the bottom surface of the second collecting trough 31 is inclined toward the first collecting trough 29. In this way, when the scraper 26 is arranged obliquely to scrape the scraps on the surface of the lower mold 22, the scraps can fall into the first collecting trough 29 along the scraper 26, so that most of the scraps can fall into the first collecting trough 29 when the scraper 26 scrapes for the first time, and a small amount of the scraps falling into the second collecting trough 31, because the bottom surface of the second collecting trough 31 is inclined toward the first collecting trough 29, the scraps in the second collecting trough 31 slide into the first collecting trough 29 under the action of gravity, thereby reducing the accumulation of scraps in the second collecting trough 31.

[0043] It should be noted that, because the scraps have a certain volume as a whole, and there are less fine granular scraps, they are easier to be scraped off. Therefore, when the push motor 28 drives the pusher 27 and the scraper 26 to move in the direction away from the push motor 28 for the first time, the scraper 26 can basically scrape all the scraps on the surface of the lower mold 22 to the collection tank. Therefore, most of the scraps can be collected mainly through the first collection tank 29 and the second collection tank 31 away from the side of the push motor 28. The push motor 28 changes the direction to drive the pusher 27 and the scraper 26 to move back and forth, which can ensure that the scraps on the surface of the lower mold 22 are scraped off more thoroughly, effectively reducing the impact on subsequent stamping work.

[0044] Preferably, please refer to Figure 1 , 2 As shown in Figure 3, in one embodiment, the unwinding assembly 1 includes a support frame, a mounting member 10, a swinging member 11, a limit member 12 and a support member 13. The mounting member 10 is rotatably mounted on the support frame. A plurality of swinging members 11 are arranged on the outer wall of the mounting member 10 along a circumferential array of the mounting member 10. The first end of the swinging member 11 is hinged to the mounting member 10. The second end of the swinging member 11 is hinged to the support member 13. The plurality of support members 13 are connected to the plurality of swinging members 11 in a one-to-one correspondence. The limit member 12 is sleeved on the mounting member 10. The limit member 12 is used to radially expand the swinging member 11 outward, thereby driving the support member 13 to press against and support the inner ring of the steel coil 2.

[0045] In order to solve the technical problem that different steel coils 2 require different dividing devices for dividing and unwinding, and there are high manufacturing costs of the dividing devices and low production efficiency due to frequent replacement of the dividing devices, the present application provides an adjustable support range to adapt to the support of the inner rings of steel coils 2 of different sizes.

[0046] It is understandable that the mounting member 10 is rotatably mounted, and the mounting member 10 can simultaneously drive the swing member 11, the limit member 12 and the support member 13 to rotate synchronously, and the support member 13 supports the steel coil 2, so it can also drive the steel coil 2 to rotate and divide the material to form the steel strip 3. The limit member 12 can slide on the mounting member 10, and by changing the position of the limit member 12, the opening of the swing member 11 can be adjusted, that is, the angle between the swing member 11 and the mounting member 10 can be adjusted, and then the distance between the support member 13 and the mounting member 10 can be adjusted, so that the diameter of the circle formed on the outer surface of each support member 13 becomes larger or smaller to meet the support requirements of steel coils 2 of different sizes, without using different specifications and sizes of dividing devices to match steel coils 2 of different sizes for dividing, which can effectively save costs, and the adjustment is very simple and efficient.

[0047] In another embodiment, the unwinding assembly 1 includes a support frame, a mounting member 10, a swinging member 11, a limit member 12, a support member 13 and a roller. The mounting member 10 is fixedly mounted on the support frame, and a plurality of swinging members 11 are arranged on the outer wall of the mounting member 10 along a circumferential array of the mounting member 10. The first end of the swinging member 11 is hinged to the mounting member 10, and the second end of the swinging member 11 is hinged to the support member 13. The plurality of support members 13 are connected to the plurality of swinging members 11 in a one-to-one correspondence. The roller is arranged on the outer wall of the support member 13, and the limit member 12 is sleeved on the mounting member 10. The limit member 12 is used to radially open the swinging member 11 outward, and then drive the roller to press against and support the inner ring of the steel coil 2 through the support member 13. The roller is used to roll relative to the inner ring of the steel coil 2 during the unwinding process.

[0048] It can be understood that the roller on the surface of the support member 13 can be rollingly connected to the inner surface of the inner ring of the steel coil 2, so that the fixed installation of the mounting member 10, the swing member 11, the limit member 12, and the support member 13 can be realized. By supporting the steel coil 2 with the roller, the rotation, material separation and unwinding operation of the steel coil 2 can still be realized, and the rolling contact between the roller and the steel coil 2 has low friction, which reduces the impact of collision and wear on the steel coil 2 during disassembly or operation.

[0049] It should be noted that the support member 13 is an arc-shaped plate structure so as to better achieve a fitting effect with the inner wall of the inner ring of the steel coil 2 .

[0050] Preferably, please refer to Figure 3As shown, the unwinding assembly 1 also includes a limiting bolt, and the mounting member 10 is provided with a plurality of limiting through holes 14 spaced apart along its length direction. The limiting bolt is used to threadably cooperate with the limiting through holes 14 and limit the limiting member 12 on opposite sides along the length direction of the mounting member 10. The limiting member 12 is used to drive the swinging member 11 to expand to different angles when it moves to different positions along the length direction of the mounting member 10.

[0051] It is understandable that the limiting bolts can be used to conveniently achieve the limiting fixation of the limiting member 12 on the mounting member 10 , thereby achieving the limiting of the position of the swing member 11 , thereby ensuring that the support member 13 stably supports the steel coil 2 .

[0052] It should be noted that the mounting member 10 may adopt a square column structure or a cylindrical structure, and both structures can realize the sleeve installation of the limiting member 12 .

[0053] Preferably, both ends of the mounting member 10 are sleeved with a limiting sleeve 15, and the bottom of the limiting sleeve 15 is supported by a support column 16. The limiting sleeve 15 can be fastened to the mounting member 10 by bolts, and the limiting sleeve 15 can be easily disassembled, so that the limiting member 12 can be conveniently sleeved and installed on the mounting member 10.

[0054] Preferably, the outer wall of the limiting member 12 is an inclined structure, so as to better fit the swinging member 11, increase the contact area between the limiting member 12 and the swinging member 11, and achieve a more stable supporting effect.

[0055] Preferably, please refer to Figure 1 and Figure 4 As shown, the feeding assembly 4 includes a first roller 6, a second roller 7, a feeding motor 9 and a tension spring 19. The first roller 6 and the second roller 7 are arranged opposite to each other and are used to clamp the opposite sides of the steel strip 3 with each other. The first roller 6 is arranged on the first rotating shaft, and the second roller 7 is arranged on the second rotating shaft. The tension spring 19 is arranged between the first rotating shaft and the second rotating shaft and is used to drive the first rotating shaft and the second rotating shaft to approach each other. The feeding motor 9 is connected to the second rotating shaft. The feeding motor 9 is used to drive the second rotating shaft to rotate, thereby driving the second roller 7 to rotate to push the steel strip 3 out of the material.

[0056] It can be understood that the feeding motor 9 can drive the second roller 7 to rotate, and the second roller 7 and the first roller 6 are both in contact with the relative surfaces of the steel strip 3. The second roller 7 actively rotates to drive the steel strip 3 to feed forward, and the first roller 6 plays a pressing role and can smooth the surface of the steel strip 3 to ensure the quality of subsequent stamping.

[0057] Preferably, both ends of the first rotating shaft are installed through the first bearing seat 18, and both ends of the second rotating shaft are installed through the second bearing seat 20, and the tension spring 19 is arranged between the first bearing seat 18 and the second bearing seat 20. The second bearing seat 20 is supported and fixed by the bearing seat bracket, so as to realize the support and installation of the second roller 7. The second roller 7 can be connected to the feeding motor 9 through the pulley assembly. Specifically, the first end of the second rotating shaft is connected to the rotating shaft 17, and the driven wheel 8 is arranged on the rotating shaft 17. The output shaft of the feeding motor 9 is connected to the driving wheel, and a belt is wound between the driving wheel and the driven wheel 8. The connection between the second roller 7 and the feeding motor 9 can be realized through a relatively low-cost transmission assembly.

[0058] Preferably, please refer to Figure 8 , 9 As shown in Figure 10, a positioning member 34 is provided at the bottom of the upper mold 21, and a positioning hole 35 is opened on the lower mold 22. The positioning member 34 is used to cooperate with the positioning hole 35 to perform positioning and guidance when the upper mold 21 and the lower mold 22 are closed. An air guide hole 38 is opened on the side wall of the positioning hole 35. The first end of the air guide hole 38 is connected to the positioning hole 35, and the second end of the air guide hole 38 is connected to the blower assembly. The blower assembly is used to blow air into the positioning hole 35 through the air guide hole 38 to blow out the debris in the positioning hole 35. A first push member 36 is provided on the side wall of the upper mold 21. The first push member 36 is used to drive the blower assembly during the movement of the upper mold 21 toward the lower mold 22.

[0059] It is understandable that, by opening an air guide hole 38 on the side wall of the positioning hole 35 of the lower mold 22, the air guide hole 38 is connected to the air blast assembly, and air is blown into the air guide hole 38 through the air blast assembly, so as to blow out the debris in the positioning hole 35, and reduce the phenomenon of jamming or offset when the positioning member 34 of the upper mold 21 cooperates with the positioning hole 35 due to the presence of debris when the upper mold 21 and the lower mold 22 are closed. Among them, the setting of the first pusher 36 can realize the automatic pushing of the air blast assembly to blow air into the air guide hole 38 when the upper mold 21 and the lower mold 22 are closed, that is, the work of automatically cleaning the debris in the positioning hole 35 is realized when the mold is closed, which is conducive to reducing the work intensity of manually operating the air blast assembly to blow air.

[0060] In one embodiment, the blowing assembly includes an elastic cover 43, a lifting plate 39 and an air inlet pipe 40. The first pushing member 36 is used to push the lifting plate 39 to move and compress the elastic cover 43 through the lifting plate 39 when the upper mold 21 moves toward the lower mold 22. The elastic cover 43 is used to enclose a compressed air cavity 42 on the base 23. A first one-way valve 44 is arranged in the air guide hole 38 along the direction of the positioning hole 35. The air inlet pipe 40 is used to connect the compressed air cavity 42 with the outside. A second one-way valve 41 is arranged in the air inlet pipe 40 along the direction of the compressed air cavity 42.

[0061] It can be understood that the elastic cover 43, the lifting plate 39 and the upper surface of the base 23 enclose the compressed air chamber 42. Since the elastic cover 43 can be driven by the lifting plate 39 to deform, compress or open, the volume of the compressed air chamber 42 can be greatly changed. When the lifting plate 39 drives the elastic cover 43 to deform and compress, the air in the compressed air chamber 42 is squeezed and then enters the positioning hole 35 through the air guide hole 38. The compressed gas has a strong impact force, which can effectively flush out the debris and impurities in the positioning hole 35, thereby improving the cleanliness of the positioning hole 35.

[0062] It should be noted that the second one-way valve 41 in the air inlet pipe 40 enables the air inlet pipe 40 to only inlet air into the air pressure chamber 42, while the first one-way valve 44 in the air guide hole 38 enables the air guide hole 38 to only guide air in one direction to the positioning hole 35, so that air is sucked through the air inlet pipe 40 when the air pressure chamber 42 is expanded, and air is blown through the air guide hole 38 when the air pressure chamber 42 is compressed. In this cyclic operation, the positioning hole 35 can be cleaned in time each time the mold is combined.

[0063] Preferably, a second pusher 37 is provided on the top of the lifting plate 39, and the first pusher 36 includes a horizontal portion and a vertical portion, wherein the horizontal portion is connected to the side wall of the upper mold 21, and the vertical portion is used to abut against the second pusher 37 and compress the second pusher 37 and the lifting plate 39 downward when the upper mold 21 and the lower mold 22 are closed. Specifically, the lifting plate 39 and the second pusher 37 are both located on the outer side of the lower mold 22.

[0064] It can be understood that the lifting plate 39 and the second pushing member 37 are both located on the outside of the lower mold 22 to avoid affecting the clamping of the upper mold 21 and the lower mold 22, and can reduce the need for high-cost operations such as grooving the lower mold 22 when the lifting plate 39 is set inside the lower mold 22, which is conducive to streamlining the structure and reducing manufacturing costs.

[0065] Preferably, the lifting plate 39 includes a telescopic inner plate and a mounting frame. The mounting frame is a frame structure with an open top. The telescopic inner plate is movably arranged in the mounting frame, and a first tension spring is arranged between the telescopic inner plate and the mounting frame. The first tension spring is used to provide an elastic force to push the telescopic inner plate away from the mounting frame.

[0066] It is understandable that the first tension spring can help the lifting plate 39 to automatically reset and rise to the highest point, so that the first pusher 36 can smoothly and accurately push the lifting plate 39 to compress it during the next mold closing. The provision of the first tension spring can save the operation of manually adjusting the lifting plate 39 to reset, and there is no need to additionally provide a limit mechanism to adjust the position of the lifting plate 39, which has a simple structure and high efficiency.

[0067] In another embodiment, the blowing assembly includes an elastic top cover, an air inlet top pipe and an air outlet pipe. The elastic top cover is made of elastic material. The elastic top cover is used to enclose a compressed air chamber 42 on the base 23. The elastic top cover is connected with the air guide hole 38 through the air outlet pipe. A first one-way valve 44 is arranged in the air guide hole 38. An air inlet top pipe is arranged on the top of the elastic top cover. A second one-way valve 41 is arranged in the air inlet top pipe. The first pushing member 36 is used to abut against the top end of the air inlet top pipe and compress the air inlet top pipe downward when the upper mold 21 moves toward the lower mold 22 and the mold is closed, thereby compressing the elastic top cover to blow the air in the compressed air chamber 42 into the air guide hole 38.

[0068] It is understandable that the elastic top cover takes in air through the top air intake pipe. When the elastic top cover is compressed, the volume of the compressed air chamber 42 is compressed, so that the air in the compressed air chamber 42 is squeezed and enters the air guide hole 38 from the air outlet pipe, and then blows air into the positioning hole 35 to clean the positioning hole 35. The use of the elastic top cover can form a compressed air chamber 42 with a variable volume through simple parts, which is conducive to simplifying the structure and is easy to replace and maintain.

[0069] It should be noted that the elastic top cover can be a bowl-shaped structure, or a square structure or a cone structure with an opening at the bottom, and the bottom end of the elastic top cover can be connected to the base 23 through a sealing ring and bolts.

[0070] Preferably, the first pusher 36 includes a horizontal portion and a vertical portion, the horizontal portion is connected to the side wall of the upper mold 21, the length of the vertical portion is greater than the diameter of the air intake top pipe, and the width of the vertical portion is less than the diameter of the air intake top pipe.

[0071] It is understandable that the width of the vertical portion of the first pusher 36 is smaller than the diameter of the air intake top pipe, which can prevent the first pusher 36 from excessively affecting the air intake of the air intake top pipe. The vertical portion only needs to push the air intake top pipe to drive the elastic top cover to undergo compression deformation. The vertical portion drives the air intake top pipe and the elastic top cover to move, which is very simple in structure, and the motion control is very direct and efficient, which is conducive to simplifying the structure and reducing manufacturing costs.

[0072] Preferably, a second tension spring is provided between the top of the elastic top cover and the base 23 , and the second tension spring is used to provide an elastic force to push the top of the elastic top cover away from the base 23 , and the air intake top pipe is located on the outside of the lower mold 22 .

[0073] It is understandable that the second tension spring can help the top of the elastic top cover to automatically reset to the highest point, assist the elastic top cover to achieve cyclic compression and expansion, and realize the air intake and blowing operation of the compressed air chamber 42. Similarly, the second tension spring can realize the reset function of the elastic top cover through simple parts, without manual reset, and can also save the additional limit adjustment mechanism to adjust the deformation of the elastic top cover. In addition, the air intake top pipe is located on the outside of the lower mold 22 to avoid affecting the mold closing of the upper mold 21 and the lower mold 22, and can reduce the need for high-cost operations such as grooving the lower mold 22 when the air intake top pipe is set inside the lower mold 22, which is conducive to streamlining the structure and reducing manufacturing costs.

[0075] The above is only a preferred embodiment of the present invention. It should be pointed out that due to the limitations of textual expression and the objective existence of infinite specific structures, ordinary technicians in this technical field can make several improvements, modifications or changes without departing from the principles of the present invention, and can also combine the above technical features in an appropriate manner; these improvements, modifications, changes or combinations, or the direct application of the inventive concept and technical solution to other occasions without improvement, should be regarded as protection of the present invention.
