Description

Technical Field

[0001] The invention relates to the technical field of stainless steel processing, in particular to a bending machine for producing stainless steel products. Background Art

[0002] Stainless steel refers to steel that is resistant to corrosion by weak media such as the atmosphere, water vapor and water. It has a smooth surface and has high plasticity, toughness and mechanical strength. It is an alloy steel that is not easy to rust and has good performance. Stainless steel usually needs to be bent when in use.

[0003] The existing patent (Announcement No.: CN108393373B) is a steel plate bending device, wherein the limit plate is fixed on the support frame, the first hydraulic cylinder is vertically fixed on the top of the support frame, the bending push plate is installed under the first bracket, the support plate is pressed on the main shaft of the stepper motor, the discharge plate is fixed on the workbench, the ultrasonic sensor is installed on the support frame, the magnetic seat is fixed on the upper surface of the stepper motor, the stepper motor is connected to the support plate, the controller is fixed on the workbench, the pressure sensor is installed between the first hydraulic cylinder and the push plate, the thrust ball is installed on the main shaft of the second hydraulic cylinder, and the second hydraulic cylinder is fixed on the support frame. The invention uses the first hydraulic cylinder to drive the push plate to fix the steel plate, and the second hydraulic cylinder drives the thrust ball to move the bending push plate forward to bend the steel plate, replacing the operation of manually bending the steel plate, thereby improving work efficiency and quality.

[0004] This invention uses hydraulic devices to replace manual bending of steel plates. Although it can reduce the workload of manual workers, some bent plates still need to be demolded during manual operation. The stainless steel processed by the bending machine still needs manual removal of small burrs caused by bending, which increases the manual work process, makes the workers' work process cumbersome, and increases the possibility of danger.

[0005] Therefore, a bending machine for producing stainless steel products is proposed. Summary of the invention

[0006] The purpose of the present invention is to provide a bending machine for the production of stainless steel products, which demolds the bent stainless steel through an elastic demolding module, and the stainless steel products that fall off the upper mold fall into a drop bin, so that the stainless steel bending machine does not need to be manually demolded, which greatly reduces the complexity of workers' operations and reduces the danger of manual operation, so as to solve the problems raised in the above-mentioned background technology.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical scheme: a bending machine for producing stainless steel products, comprising a base, wherein guide pillars are fixedly connected at the corners of the upper outer surface of the base, a hydraulic slide block is slidably sleeved at the middle position of the guide pillar, the upper end of the guide pillar is fixedly connected to the upper base, the upper outer surface of the upper base is fixedly connected to the hydraulic cylinder, both sides of the lower outer surface of the hydraulic cylinder are movably connected with hydraulic pistons, and the lower end of the hydraulic piston passes through and extends to the bottom of the hydraulic slide block, an upper die seat is fixedly connected at the middle position of the lower outer surface of the hydraulic slide block, an upper die guide sleeve is fixedly connected at the corners of the lower outer surface of the upper die seat, a base is fixedly connected to the left side of the upper outer surface of the base, a lower die seat is slidably connected to the upper outer surface of the base, a lower die guide pillar is fixedly connected to the upper outer surface of the base, the upper die guide sleeve is sleeved on the lower die guide pillar, the lower outer surface of the lower die seat is fixedly connected to the lower die, and the rear end oblique end surface of the lower die seat is slidably connected to the side pressure lower die;

[0008] A material drop bin is fixedly connected to the outer surface of the upper end of the base near the right side, the middle parts of the front and rear ends of the material drop bin are open, and a discharge shaft is fixedly connected to the middle position of the inner surfaces of the front and rear ends of the material drop bin near the upper end, an elastic stripping module is movably sleeved on the outside of the discharge shaft, and a discharge spring is fixedly connected between the rear end face of the elastic stripping module and the material drop bin.

[0009] After the equipment is powered on and the hydraulic system is started, the sheet is first placed on the bending station, and then the hydraulic cylinder pushes the hydraulic slide downward, the hydraulic slide drives the upper die seat downward, and the bending machine bends the stainless steel plate at the bending station, and then the stainless steel sheet is separated from the lower die, and the processed stainless steel sheet moves with the upper die seat. When the stainless steel product is directly above the blanking bin, the hydraulic cylinder then pushes the hydraulic slide downward, the hydraulic slide drives the upper die seat downward, and the stainless steel product follows the upper die seat downward. The elastic stripping module is in a balanced state under the action of the unloading spring. When the stainless steel product is driven to contact the elastic stripping module, the elastic stripping module is squeezed by the stainless steel product, and the elastic stripping module is squeezed inward. The elastic stripping module squeezes the spring, and the stainless steel product can smoothly go down to the bottom of the elastic stripping module. After the stainless steel product passes through the elastic stripping module, the elastic stripping module will return to a balanced state due to the elastic force of the spring. Then the hydraulic slide moves upward, driving the upper die seat and the stainless steel product upward. When the stainless steel product contacts the elastic stripping module, it will be unable to go up due to the obstruction of the elastic stripping module, and it will fall off and fall into the blanking bin. The stainless steel bending machine does not need manual demoulding, which greatly reduces the complexity of workers' operations, reduces the danger of manual operation, and improves the production efficiency of stainless steel products.

[0010] Preferably, a positioning block is fixedly connected to the upper outer surface of the lower die base near the rear end, a positioning wheel seat is fixedly connected to the upper end of the lower die base near the front end, a small motor is fixedly connected to the right outer surface of the positioning wheel seat, a positioning wheel is rotatably connected to the interior of the positioning wheel seat near the upper end, and the positioning wheel and the small motor are rotatably connected.

[0011] After the equipment is powered on, first place the stainless steel sheet to be processed on the bending station. The front end of the stainless steel sheet contacts the positioning wheel, and the rear end contacts the positioning block. Then the small motor rotates, and the small motor drives the positioning wheel to rotate. The positioning wheel will apply a force pointing to the positioning block to the lower end of the sheet. This force can replace manual work to push the sheet toward the positioning block, so that the sheet and the positioning block are in close contact, which plays a role in positioning. When the worker positions the sheet, his hand will inevitably touch the mold, which creates a certain risk. The use of positioning blocks and positioning wheels can make it possible for the worker's hand to not touch the workpiece, and the machine itself can position the sheet, reducing the risk of manual operation.

[0012] Preferably, the lower parts of the outer surfaces on both sides of the upper mold base are fixedly connected with lead screw sleeves, a lead screw is rotatably connected between the lead screw sleeves, a servo motor is fixedly connected to the left side of the lead screw, a T-shaped groove is provided at the lower end of the upper mold base, a lead screw nut is slidably connected inside the T-shaped groove, the lead screw nut is sleeved on the middle part of the lead screw, a ball is rotatably connected between the lead screw nut and the lead screw, and the lower end of the lead screw nut is fixedly connected to the upper mold.

[0013] After the equipment is powered on, the upper die is above the bending station. When the sheet metal is bent at the bending station and the upper die moves upward to the specified position, the servo motor starts to rotate forward when it receives a pulse signal that causes the motor to rotate forward, driving the lead screw to rotate. The ball screw mechanism can convert rotary motion into linear motion. The lead screw nut slidably connected in the T-shaped slide can drive the upper die to complete the displacement from the bending station to the demolding station under the action of the lead screw's rotary motion. When the servo motor receives a pulse signal that causes the motor to reverse, it starts to reverse, and the lead screw nut drives the upper die to move from the demolding station to the bending station. When the workpiece is in the bending process, the drivable servo motor of the equipment drives the workpiece to move from the bending station to the demolding station. After the demolding is completed, it can drive the upper die to the bending station to realize the reciprocating motion of the mold.

[0014] Preferably, the interior of the material drop bin is fixedly connected with a clamping plate shaft near both sides of the lower end, the middle part of the clamping plate shaft is rotatably sleeved with a clamping plate, the upper half of the clamping plate is open, and the two clamping plates are fixedly connected with a grinding plate on one side near the material drop bin, a spring is fixedly connected between the clamping plate and the material drop bin, and a stop pin is fixedly connected to the inner surface of the front end of the material drop bin near both sides.

[0015] After the equipment is powered on, the bent sheet is brought to the top of the demolding station, the upper die moves downward, and the upper die opens the splint with an open upper part. At the same time, the splint will compress the spring because it is opened by the upper die, so that the processed sheet can fall smoothly into the blanking bin. Then the upper die moves upward and leaves the splint, and the splint is squeezed inward by the elastic force of the spring. The stop pin can block the splint squeezed by the spring, so that the splint will not tilt into the inside of the blanking bin. Under the action of the spring, the splint will clamp the stainless steel products, and the stainless steel products will be shaped by the splint after falling, so that the stainless steel products can be stacked neatly, and it can also ensure that the subsequent pushing process will not be disturbed.

[0016] Preferably, the upper outer surface of the base is located behind the material drop bin and is fixedly connected to a push rod adjustment plate, the upper outer surface of the push rod adjustment plate is fixedly connected to a push rod, the front end of the push rod is movably connected to a push plate, the push plate is located in the middle position of the rear end of the material drop bin, and the front of the material drop bin is movably connected to a box.

[0017] After bending, the stainless steel products fall off from the upper die after passing through the elastic stripping module. Because the upper die will open the splint when it goes down, the stainless steel products will fall smoothly between the two splints after falling off from the upper die. When the upper die goes up, the upper die leaves the splint, and the splint clamps the stainless steel products due to the action of the spring. After the bending machine completes the bending of a predetermined number of stainless steel products, it starts the push rod to push the clamped stainless steel products out of the drop bin into the box. Because the two sides of the stainless steel products are in contact with the grinding plates on the splints, the grinding plates will remove the fine burrs on the stainless steel products when the push rod pushes the stainless steel products out of the drop bin. There is no need for workers to grind and pack them, which reduces the production process of stainless steel products and improves the production efficiency of stainless steel products.

[0018] Preferably, a chip cleaning push plate is fixedly connected to the lower end of the push plate.

[0019] When the push rod removes the tiny burrs on the stainless steel products, tiny metal debris will be generated. The chip cleaning push plate connected to the push plate can push the debris generated by grinding out of the drop bin. The accumulation of debris will cause obstacles to the operation of the equipment. Cleaning the debris can make the equipment run more stably.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. By setting the positioning wheel, positioning block and other components, the positioning wheel will continuously apply a force to the sheet metal to push the positioning block after it rotates, so that the worker does not need to press and fix the sheet metal by hand after placing it on the bending machine, thus ensuring the safety of the worker;

[0022] 2. By setting up mechanisms such as ball screws, elastic demolding modules, splints, grinding plates and push rods, after the bending machine bends the stainless steel sheet, there is no need to manually demold it, and the bent stainless steel products can be neatly stacked together. The grinding plate can grind the sides of the stainless steel products, and the debris after grinding can also be cleaned up, which reduces the labor intensity of workers and ensures the safety of workers.

DETAILED DESCRIPTION

[0033] 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.

[0034] See also Figures 1 to 9 , the present invention provides a technical solution:

[0035] A bending machine for producing stainless steel products, such as Figure 1 , Figure 3 , Figures 6 to 8 As shown, it includes a base 1, a guide column 2 is fixedly connected to the corner of the upper outer surface of the base 1, a hydraulic slider 3 is slidably sleeved in the middle position of the guide column 2, an upper base 4 is fixedly connected to the upper end of the guide column 2, a hydraulic cylinder 5 is fixedly connected to the upper outer surface of the upper base 4, both sides of the lower outer surface of the hydraulic cylinder 5 are movably connected to hydraulic pistons 6, and the lower end of the hydraulic piston 6 penetrates and extends to the bottom of the hydraulic slider 3, and an upper die seat is fixedly connected to the middle position of the lower outer surface of the hydraulic slider 3 29, an upper die guide sleeve 27 is fixedly connected to the corner of the lower outer surface of the upper die seat 29, a base 7 is fixedly connected to the left side of the upper outer surface of the base 1, a lower die seat 8 is slidably connected to the upper outer surface of the base 7, a lower die guide column 28 is fixedly connected to the corner of the upper outer surface of the base 7, the upper die guide sleeve 27 is sleeved on the lower die guide column 28, a lower die 17 is fixedly connected to the inner lower outer surface of the lower die seat 8, and a side pressure lower die 14 is slidably connected to the inner rear end oblique end surface of the lower die seat 8;

[0036] A material drop bin 19 is fixedly connected to the outer surface of the upper end of the base 1 near the right side, and the middle parts of the front and rear ends of the material drop bin 19 are open. A discharge shaft 30 is fixedly connected to the middle position of the inner surface of the front and rear ends of the material drop bin 19 near the upper end. An elastic stripping module 24 is movably sleeved on the outside of the discharge shaft 30, and a discharge spring 31 is fixedly connected between the rear end surface of the elastic stripping module 24 and the material drop bin 19;

[0037] During operation, the equipment is powered on and the hydraulic system is started. First, the sheet is placed on the bending station, and then the hydraulic cylinder 5 pushes the hydraulic slide 3 downward, which drives the upper die seat 29 downward. The bending machine bends the stainless steel sheet at the bending station, and the processed stainless steel sheet moves with the upper die seat 29. When the stainless steel product is directly above the blanking bin 19, the hydraulic cylinder 5 then pushes the hydraulic slide 3 downward, which drives the upper die seat 29 downward, and the stainless steel product follows the upper die seat 29 downward. The elastic stripping module 24 is in a balanced state under the action of the unloading spring 31. When the stainless steel product is driven and elastically disengaged, the elastic stripping module 24 is in a balanced state. When the elastic stripping module 24 contacts, the elastic stripping module 24 is squeezed by the stainless steel product, and the elastic stripping module 24 is squeezed inward. The elastic stripping module 24 squeezes the discharge spring 31, and the stainless steel product can smoothly go down to the bottom of the elastic stripping module 24. After the stainless steel product passes through the elastic stripping module 24, the elastic stripping module 24 will return to a balanced state due to the elastic force of the discharge spring 31. Then the hydraulic slide 3 moves upward, driving the upper die seat 29 and the stainless steel product upward. When the stainless steel product contacts the elastic stripping module 24, it will be unable to move upward due to the obstruction of the elastic stripping module 24, and will fall off and fall into the inside of the drop bin 19. The stainless steel bending machine does not need to be manually demolded, which greatly reduces the complexity of the worker's operation, reduces the danger of manual operation, and improves the production efficiency of stainless steel products.

[0038] As an embodiment of the present invention, Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, a positioning block 13 is fixedly connected to the upper outer surface of the lower die base 8 near the rear end, a positioning wheel seat 34 is fixedly connected to the upper end of the lower die base 8 near the front end, a small motor 9 is fixedly connected to the right outer surface of the positioning wheel seat 34, a positioning wheel 15 is rotatably connected to the inner part of the positioning wheel seat 34 near the upper end, and the positioning wheel 15 is rotatably connected to the small motor 9;

[0039] When working, the equipment is powered on, and the stainless steel sheet to be processed is first placed on the bending station. The front end of the stainless steel sheet contacts the positioning wheel 15, and the rear end contacts the positioning block 13. Then the small motor 9 rotates, and the small motor 9 drives the positioning wheel 15 to rotate. The positioning wheel 15 will apply a force pointing to the positioning block 13 to the lower end of the sheet. This force can replace the manual push of the sheet toward the positioning block 13, so that the sheet and the positioning block 13 are in close contact, which plays a role in positioning. When the worker positions the sheet, his hand will inevitably touch the mold, which creates a certain risk. The use of the positioning block 13 and the positioning wheel 15 can make it possible for the worker's hand to not touch the workpiece, and the machine itself can position the sheet, reducing the risk of manual operation.

[0040] As an embodiment of the present invention, Figure 5 and Figure 7 As shown, the lower parts of the outer surfaces of both sides of the upper die seat 29 are fixedly connected with lead screw sleeves 33, the lead screw 11 is rotatably connected between the lead screw sleeves 33, the left side of the lead screw 11 is fixedly connected with a servo motor 10, the lower end of the upper die seat 29 is provided with a T-shaped slot 18, the inside of the T-shaped slot 18 is slidably connected with a lead screw nut 12, the lead screw nut 12 is sleeved on the middle part of the lead screw 11, a ball 35 is rotatably connected between the lead screw nut 12 and the lead screw 11, and the lower end of the lead screw nut 12 is fixedly connected with an upper die 16;

[0041] During operation, the equipment is powered on, the upper die 16 is above the bending station, and the upper die holder 29 moves downward, driving the upper die to move downward. Under the joint action of the upper die 16, the lower die 17 and the side pressure lower die 14, the sheet is bent at the bending station. The bent stainless steel sheet will be clamped on the outer surface of the upper die 16 due to the bent shape. Therefore, the stainless steel sheet will move upward with the upper die 16 due to the upward friction of the outer surface of the upper die 16 and separate from the lower die 17. The upper die holder 29 moves upward. After the upper die 16 moves upward to the specified position, When the servo motor 10 receives a pulse signal that causes the motor to rotate forward, it starts to rotate forward, driving the lead screw 11 to rotate. The ball screw mechanism can convert the rotary motion into linear motion. The lead screw nut 12 slidably connected in the T-shaped slot 18 can drive the upper mold 16 to complete the displacement from the bending station to the demolding station under the rotary motion of the lead screw 11. When the servo motor 10 receives a pulse signal that causes the motor to reverse, it starts to reverse, and the lead screw nut 12 drives the upper mold 16 to move from the demolding station to the bending station. When the workpiece is in the bending process, the drivable servo motor 10 of the equipment drives the workpiece to move from the bending station to the demolding station. After the demolding is completed, it can drive the upper mold 16 to the bending station to realize the reciprocating motion of the mold.

[0042] As an embodiment of the present invention, Figure 5 , Figure 8 and Fig. 9 As shown, the positions of the inner part of the drop bin 19 near the lower end are fixedly connected with a clamping plate shaft 23, the middle part of the clamping plate shaft 23 is rotatably sleeved with a clamping plate 20, the upper half of the clamping plate 20 is in an open shape, and the two clamping plates 20 are fixedly connected with a grinding plate 32 on one side near the drop bin 19, a spring 22 is fixedly connected between the clamping plate 20 and the drop bin 19, and the inner surface of the front end of the drop bin 19 is fixedly connected with a stop pin 38 near the two sides;

[0043] During operation, after the equipment is powered on, the bent sheet is brought to the top of the demolding station, and the upper mold 16 moves downward, and the upper mold 16 opens the splint 20 with an open upper part. At the same time, the splint 20 will compress the spring 22 because it is opened by the upper mold, so that the processed sheet can fall smoothly into the blanking bin 19, and then the upper mold 16 moves upward to leave the splint 20, and the splint 20 will be squeezed inward by the elastic force of the spring 22. The stop pin 38 can block the splint 20 squeezed by the spring 22, so that the splint 20 will not tilt into the inside of the blanking bin 19. Under the action of the spring 22, the splint 20 will clamp the stainless steel product, and the stainless steel product will be shaped by the splint 20 after falling, so that the stainless steel products can be stacked neatly, and it can also ensure that the subsequent pushing process will not be disturbed.

[0044] As an embodiment of the present invention, Figure 1 and Figure 2 As shown, the upper outer surface of the base 1 is located behind the drop bin 19 and is fixedly connected to a push rod adjustment plate 26, the upper outer surface of the push rod adjustment plate 26 is fixedly connected to a push rod 25, the front end of the push rod 25 is movably connected to a push plate 21, the push plate 21 is located in the middle of the rear end of the drop bin 19, and the front of the drop bin 19 is movably connected to a box 36;

[0045] During operation, the stainless steel product after bending is dropped from the upper die after passing through the elastic stripping module 24. Because the upper die will stretch the splint 20 when it moves downward, the stainless steel product will smoothly fall between the two splints 20 after dropping from the upper die 16. When the upper die 16 moves upward, the upper die 16 leaves the splint, and the splint 20 clamps the stainless steel product due to the action of the spring 22. After the bending machine completes bending a predetermined number of stainless steel products, it starts the push rod 25 to push the clamped stainless steel product out of the drop bin 19 and into the box 36. The two sides of the stainless steel product are in contact with the grinding plate 32 on the splint 20. Therefore, when the push rod 25 pushes the stainless steel product out of the drop bin 19, the grinding plate 32 will remove the fine burrs on the stainless steel product, and there is no need for workers to grind and pack it, which reduces the production process of stainless steel products and improves the production efficiency of stainless steel products.

[0046] As an embodiment of the present invention, Fig. 9 As shown, the lower end of the push plate 21 is fixedly connected with a chip cleaning push plate 37;

[0047] During operation, the push rod 25 will produce fine metal debris when removing the fine burrs on the stainless steel product. The chip cleaning push plate 37 connected to the push plate 21 can push the debris generated by grinding out of the material bin. The accumulation of debris will cause obstacles to the operation of the equipment. Cleaning the debris can make the operation of the equipment more stable.

[0048] Working principle:

[0049] During operation, the equipment is powered on, the hydraulic system is started, and the stainless steel sheet to be processed is placed on the bending station. The front end of the stainless steel sheet contacts the positioning wheel 15, and the rear end contacts the positioning block 13. Then the small motor 9 rotates, and the small motor 9 drives the positioning wheel 15 to rotate. The positioning wheel 15 will apply a force pointing to the positioning block 13 to the lower end surface of the sheet. This force can replace manual work to push the sheet toward the positioning block 13, so that the sheet and the positioning block 13 are in close contact and play a positioning role. Then the hydraulic cylinder 5 pushes the hydraulic slide 3 downward, and the hydraulic slide 3 drives the upper die seat 29 downward. The bending machine bends the stainless steel plate at the bending station, and then the stainless steel sheet is separated from the lower die 17. The processed stainless steel sheet moves with the upper die seat 29, and the upper die 16 moves upward to After the specified position, the servo motor 10 starts to rotate forward when it receives a pulse signal that makes the motor rotate forward, driving the screw 11 to rotate. The ball screw mechanism can convert the rotary motion into linear motion. The screw nut 12 slidably connected in the T-shaped slide groove 18 can drive the upper mold 16 to complete the displacement from the bending station to the demolding station under the action of the rotary motion of the screw 11. When the servo motor 10 receives a pulse signal that makes the motor reverse, it starts to reverse, and the screw nut 12 drives the upper mold 16 to move from the demolding station to the bending station, so as to realize the reciprocating motion of the stainless steel product between the bending station and the demolding station. When the stainless steel product is directly above the blanking bin 19, the hydraulic cylinder 5 then pushes the hydraulic slide block 3 downward, and the hydraulic slide block 3 drives the upper mold base 29 downward. The stainless steel product Following the downward movement of the upper die seat 29, the elastic stripping module 24 is in a balanced state under the action of the discharge spring 31. When the stainless steel product is driven to contact the elastic stripping module 24, the elastic stripping module 24 is squeezed by the stainless steel product, squeezing the elastic stripping module 24 inward. The elastic stripping module 24 squeezes the discharge spring 31, and the stainless steel product can smoothly descend to the bottom of the elastic stripping module 24. After the stainless steel product passes through the elastic stripping module 24, the elastic stripping module 24 will return to a balanced state due to the elastic force of the discharge spring 31. Then the hydraulic slide 3 moves upward, driving the upper die seat 29 and the stainless steel product upward. When the stainless steel product contacts the elastic stripping module 24, it cannot move upward due to the obstruction of the elastic stripping module 24, and it will fall off and fall into the inside of the drop bin 19. Then the upper die 1 6 moves upward and leaves the clamping plate 20. The clamping plate 20 will be squeezed inward by the elastic force of the spring 22. The stop pin 38 can stop the clamping plate 20 squeezed by the spring 22, so that the clamping plate 20 will not tilt into the inside of the blanking bin 19, so as to ensure that the pushing process will not be disturbed later. The clamping plate 20 clamps the stainless steel product due to the action of the spring 22. After the bending machine completes bending a predetermined number of stainless steel products, it starts the push rod 25 to push the clamped stainless steel product out of the blanking bin 19. The two sides of the stainless steel product are in contact with the grinding plate 32 on the clamping plate 20. Therefore, when the push rod 25 pushes the stainless steel product out of the blanking bin 19, the grinding plate 32 will remove the fine burrs on the stainless steel product. When the push rod 25 removes the fine burrs on the stainless steel product, fine metal debris will be generated.The chip removal push plate 37 connected to the push plate 21 can push the chips generated by grinding out of the material bin.
