Description

Technical Field

[0001] The invention relates to the technical field of steel back punching, and in particular to an open tilting punch press and a method for steel back punching. Background Art

[0002] The steel back is an important component of small car brake pads. It is mainly used to carry and support the friction block, and to withstand and transmit the huge force generated during braking. The steel back is usually made of stamped steel plates. It has high strength and rigidity, can withstand huge pressure during braking, and protect the friction block from damage. It is one of the key components for the normal operation of the brake system.

[0003] When manufacturing steel backs, an open tilting punch press is needed. The open tilting punch press press generally uses a crank connecting rod as the working mechanism. It can be used for cutting, punching, blanking, bending, shallow drawing, forming and other various cold stamping processes. Its body can be tilted 25° to facilitate the sliding of stamped products or waste from the die. When processing the steel back, first determine the appropriate processing procedures and tools based on the shape, size and use requirements of the steel back, then place the blank on the workbench, and after fixing the blank, you can process the steel back according to the requirements of the processing technology.

[0004] During the stamping process, the distance between the upper die and the lower die needs to be adjusted. This distance is called the punch stroke, which determines the range of movement of the punch during the stamping process. If the punch stroke is too large, it will make it difficult for the upper die to fully contact the workpiece, resulting in punch offset. If the punch stroke is too small, the upper die will not be able to completely separate from the workpiece, causing damage to the upper die, greatly affecting work efficiency, and easily resulting in deformation and damage of the workpiece.

After the stamping is completed, the stamped steel back can be removed.

[0026] like Figure 3 As shown, the stamping machine frame 2 is fixedly installed in the stamping area, the stamping machine frame 2 is located at the upper part of the stamping assembly, the displacement assembly is installed on the stamping machine frame 2, and is used to drive the stamping assembly to work, and its displacement assembly includes a crankshaft 10, a hinge support 11, a connecting rod 12 and a driving part, the crankshaft 10 is rotatably installed inside the stamping machine frame 2, the hinge support 11 is fixedly installed on the top of the sliding frame 6, the connecting rod 12 is rotatably installed on the hinge support 11, the upper end of the connecting rod 12 is rotatably connected to the connecting journal of the crankshaft 10, and the driving part is installed on the punching machine frame 1, and is used to drive the crankshaft 10 to rotate.

[0027] Specifically, during the stamping process, the driving unit is started, and the driving unit drives the crankshaft 10 to rotate, and the crankshaft 10 drives the connecting rod 12 to move, and the connecting rod 12 pushes the hinge support 11 to move, thereby pushing the sliding frame 6 to move. At this time, relative rotation occurs between the connecting rod 12 and the hinge support 11, and between the connecting rod 12 and the connecting journal of the crankshaft 10, thereby driving the sliding frame 6 to reciprocate on the slide rail 5.

[0028] The above, such as Figure 3 As shown, its driving part includes a first motor 13, a driven pulley 14, a driving pulley 15 and a transmission belt 16.

If the brakes are not applied in time, the workpiece or equipment may be damaged, and in severe cases, personal safety accidents may occur. Therefore, it is necessary to brake the crankshaft 10 when necessary. When braking is required, the first electric cylinder 19 is started, and the first electric cylinder 19 drives the brake block 20 to move. The brake block 20 contacts the brake disc 17, thereby fixing the brake disc 17, thereby fixing the crankshaft 10, achieving quick stopping, saving time, and improving production efficiency.

[0032] like Figures 6 to 8 As shown, the loading area is provided with a mounting groove 3, on which a lifting seat 4 is slidably mounted, and a positioning assembly is mounted on the punch press frame 1 for adjusting the position of the lifting seat 4, wherein the positioning assembly comprises a fixed cylinder 21, a positioning screw 22, a positioning cylinder 23, a positioning nut 24 and a driving portion, and two fixed cylinders 21 are symmetrically and fixedly mounted on the loading area, and positioning screws 22 are rotatably mounted inside the two fixed cylinders 21, and a positioning cylinder 23 is slidably mounted on each fixed cylinder 21, and the two positioning cylinders 23 are fixedly connected to the lifting seat 4, and positioning nuts 24 are threadedly sleeved on the two positioning screws 22, and the positioning nuts 24 are fixedly connected to the positioning screws 22, and the driving portion is mounted at the lower part of the fixed cylinder 21 for driving the two positioning nuts 24 to rotate simultaneously.

[0033] Specifically, when adjusting the lifting seat 4, the driving part is set to drive the two adjusting screws 22 to rotate at the same time, the adjusting screw 22 drives the adjusting nut 24 to move, and the adjusting nut 24 drives the adjusting cylinder 23 to move, until the adjusting cylinder 23 drives the lifting seat 4 to move to the set position, then the driving part can be closed, the position of the adjusting screw 22 can be fixed, and the position of the lifting seat 4 can be adjusted.

[0034] The above, such as Figure 6 , Figure 7As shown, its driving part includes a mounting frame 25, a second motor 26, a transmission rod 27, a driven bevel gear 28 and a driving bevel gear 29. The mounting frame 25 is fixedly mounted on the lower part of the two fixed cylinders 21, the second motor 26 is fixedly mounted inside the mounting frame 25, the output end of the second motor 26 is fixedly mounted with a transmission rod 27, the other end of the transmission rod 27 is rotatably connected to the mounting frame 25, the bottom of the two adjusting screws 22 is fixedly mounted with a driven bevel gear 28, the driven bevel gear 28 is located inside the mounting frame 25, and two driving bevel gears 29 are fixedly mounted on the transmission rod 27, and the driving bevel gear 29 is meshed with the driven bevel gear 28.

[0035] Specifically, when adjusting the position of the lifting seat 4, the second motor 26 is started, the second motor 26 drives the transmission rod 27 to rotate, the transmission rod 27 drives the active bevel gear 29 to rotate, the active bevel gear 29 drives the driven bevel gear 28 to rotate, thereby driving the adjustment screw 22 to rotate.

[0036] like Fig. 9 As shown, the fixing component is installed on the lifting seat 4, and is used to fix the steel back to be punched. The fixing component includes a fixing groove 30, a pushing frame 31, a second electric cylinder 32 and an abutment portion. The lifting seat 4 is provided with four fixing grooves 30 in a circular shape with equal angles, and each two opposite fixing grooves 30 are arranged symmetrically. A pushing frame 31 is slidably installed on each fixing groove 30, and a second electric cylinder 32 is fixedly installed on each fixing groove 30. The output end of the second electric cylinder 32 is fixedly connected to the pushing frame 31, and an abutment portion is installed on each pushing frame 31 for fixing the steel back.

[0037] Specifically, after the blank is placed on the lower die 9, the position of the blank needs to be fixed. At this time, the second electric cylinder 32 is started, and the second electric cylinder 32 drives the pushing frame 31 to move on the fixed groove 30. The pushing frame 31 drives the abutting part to move until the abutting part contacts the blank, fixes the position of the blank, and then the stamping process can begin.

[0038] The above, such as Fig. 9 As shown, the abutting portion includes a fixed block 33 and a spring 34 . A fixed block 33 is slidably mounted on each push frame 31 . Springs 34 are fixedly mounted at both ends of each fixed block 33 . The springs 34 are fixedly connected to the inner side wall of the push frame 31 .

[0039] Specifically, as the pushing frame 31 moves, the pushing frame 31 drives the fixed block 33 to move through the spring 34. When the fixed block 33 contacts the blank, the spring 34 is deformed, so that the contact between the fixed block 33 and the blank is closer, and the possibility of the blank being crushed is reduced, thereby improving the accuracy of positioning.

[0040] To sum up, when stamping and producing the steel back, first install the corresponding upper mold 8 and lower mold 9, install the upper mold 8 on the mounting seat 7, and install the lower mold 9 on the lifting seat 4, and then adjust the position of the lifting seat 4. At this time, start the second motor 26, and the second motor 26 drives the transmission rod 27 to rotate, and the transmission rod 27 drives the active bevel gear 29 to rotate, and the active bevel gear 29 drives the driven bevel gear 28 to rotate, thereby driving the adjusting screw 22 to rotate, and the adjusting screw 22 drives the adjusting nut 24 to move, and the adjusting nut 24 drives the adjusting cylinder 23 to move, until the adjusting cylinder 23 drives the lifting seat 4 to move to the set position, the second motor 26 can be turned off, the position of the adjusting screw 22 is fixed, and the position of the lifting seat 4 can be adjusted.

[0041] Then the blank is placed on the lower die 9. At this time, the position of the blank needs to be fixed to avoid the blank shifting during the stamping process, which may cause problems in the stamping. At this time, the second electric cylinder 32 is started, and the second electric cylinder 32 drives the pushing frame 31 to move on the fixed groove 30. As the pushing frame 31 moves, the pushing frame 31 drives the fixed block 33 to move through the spring 34. When the fixed block 33 contacts the blank, the spring 34 is deformed at this time, so that the contact between the fixed block 33 and the blank is closer, and the possibility of the blank being crushed is reduced, the positioning accuracy is improved, and the stamping process can be started.

[0042] After fixing the position of the blank, start the first motor 13, the first motor 13 drives the active pulley 15 to rotate, the active pulley 15 drives the driven pulley 14 to rotate through the transmission belt 16, thereby driving the crankshaft 10 to rotate, the crankshaft 10 drives the connecting rod 12 to move, the connecting rod 12 pushes the hinge support 11 to move, thereby pushing the sliding frame 6 to move, at this time, relative rotation occurs between the connecting rod 12 and the hinge support 11, and between the connecting rod 12 and the connecting journal of the crankshaft 10, thereby driving the sliding frame 6 to reciprocate on the slide rail 5.

[0043] When the sliding frame 6 drives the upper mold 8 to move to the lowest position of the stroke through the mounting seat 7, the upper mold 8 and the lower mold 9 fit together just right, thereby ensuring the stability of the stamping and avoiding the problem of deformation and damage of the workpiece during the stamping process due to inappropriate setting of the stamping stroke. After the stamping is completed, the stamped steel back can be removed.

[0044] During the operation of the punch press, impact force may be generated suddenly. If the brake is not applied in time, the workpiece or equipment may be damaged, and in serious cases, personal safety accidents may occur. Therefore, it is necessary to brake the crankshaft 10 when necessary. When braking is required, the first electric cylinder 19 is started, and the first electric cylinder 19 drives the brake block 20 to move. The brake block 20 contacts the brake disc 17, thereby fixing the brake disc 17, thereby fixing the crankshaft 10, achieving quick parking, saving time, and improving production efficiency.

[0045] Embodiment 2 On the basis of the first embodiment, this embodiment further discloses a steel back punching method, using the above-mentioned open tilting punch press for steel back punching, comprising the following steps: The first step is installation.

After the adjusting cylinder 23 drives the lifting seat 4 to move to the set position, the second motor 26 can be turned off, and the position of the adjusting screw 22 can be fixed to adjust the position of the lifting seat 4. The fourth step is to place the blank into the lower mold 9; The fifth step is moving. At this time, the position of the blank needs to be fixed to avoid the blank shifting during the stamping process, which may cause stamping problems. At this time, the second electric cylinder 32 is started, and the second electric cylinder 32 drives the push frame 31 to move on the fixed groove 30. As the push frame 31 moves, the push frame 31 drives the fixed block 33 to move through the spring 34; Step 6: Positioning. When the fixing block 33 contacts the blank, the spring 34 is deformed, so that the fixing block 33 and the blank are in closer contact, and the possibility of the blank being crushed is reduced, and the accuracy of positioning is improved, and the stamping process can be started. Step 7: start the first motor 13, the first motor 13 drives the driving pulley 15 to rotate, the driving pulley 15 drives the driven pulley 14 to rotate through the transmission belt 16, thereby driving the crankshaft 10 to rotate; Step 8: displacement. The crankshaft 10 drives the connecting rod 12 to move. The connecting rod 12 drives the hinge support 11 to move, thereby driving the sliding frame 6 to move. At this time, the connecting rod 12 and the hinge support 11, as well as the connecting journal of the connecting rod 12 and the crankshaft 10, rotate relative to each other, thereby driving the sliding frame 6 to reciprocate on the slide rail 5. The ninth step is stamping. The sliding frame 6 drives the upper die 8 to move through the mounting seat 7, thereby stamping the blank on the lower die 9; The tenth step is braking. During the operation of the punch press, impact force may be generated suddenly. If braking is not performed in time, the workpiece or equipment may be damaged, and in serious cases, personal safety accidents may occur. Therefore, it is necessary to brake the crankshaft 10 when necessary. When braking is required, the first electric cylinder 19 is started, and the first electric cylinder 19 drives the brake block 20 to move. The brake block 20 contacts the brake disc 17, thereby fixing the brake disc 17, thereby fixing the crankshaft 10, achieving rapid parking, saving time, and improving production efficiency.
