Description

Technical Field

[0001] The utility model relates to the technical field of bending machines, in particular to a novel bending machine oil cylinder with a flexible oil intake control structure. Background Art

[0002] The oil cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion (or swinging motion). It has a simple structure and reliable operation. When using it to achieve reciprocating motion, the deceleration device can be eliminated, and there is no transmission gap and the movement is smooth. Therefore, it is widely used in the hydraulic systems of various machines.

[0003] A search of Chinese utility model patents (publication number CN216447229U) disclosed a safety-type bending machine cylinder, which includes a cylinder body, an assembly block, a mounting hole, an oil filling hole, a cap, a filter, a support ring and a sampling mechanism. This technical solution can slowly rotate the valve cover through devices such as an adjusting disk, a sleeve rod and a push rod to prevent the internal pressure of the cylinder body from being too high and causing hydraulic oil leakage. The collection tube is fixedly connected to the inside of the sampling mechanism to facilitate sampling of the hydraulic oil.

[0004] However, the inventors have discovered that this technical solution still has at least the following defects:

[0005] The existing hydraulic cylinder of the bending machine cannot flexibly control the oil supply, which makes it difficult to accurately control the bending angle, affects the depth and position of the bending, causes product inconsistency, greatly reduces work efficiency, increases production costs, affects production progress, and causes unnecessary energy waste. Utility Model Content

[0006] The utility model aims to provide a novel hydraulic cylinder for a bending machine with a flexible oil inlet control structure, so as to solve the problems raised in the above-mentioned background technology.

[0007] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions:

[0008] The cam is connected with the oil pump rod and the oil pump end cover is provided with an oil pumping hole, and the oil pump end cover is provided with an oil pumping hole, and the oil pump end cover is provided with an oil pumping hole.

[0009] Preferably, the cylinder body is connected to a sampling box, the sampling box is rotatably connected to a second screw, the second screw is connected to an adjustment handle, the sampling box is slidably connected to a sleeve rod, the sleeve rod is threadedly connected to the second screw, the sleeve rod is rotatably connected to a push rod, the cylinder body is rotatably connected to a valve cover, and the valve cover is rotatably connected to the push rod.

[0010] Preferably, the sampling box is connected to a pressure gauge.

[0011] Preferably, the oil cylinder body is connected to an assembly block, and the assembly block is provided with a mounting hole.

[0012] Preferably, a filter screen is connected to the side wall of the oil filling hole.

[0013] Preferably, the piston is connected to a sealing ring, and the piston is connected to a support ring.

[0014] Compared with the existing technology, this technical solution has the following beneficial effects:

[0015] (1) This solution enables the oil cylinder to flexibly control the oil intake by setting up an extension chamber, an oil inlet pipe, a baffle, a flow meter, a motor, a first screw and a controller. The flow meter establishes a signal connection with the controller. When the flow meter detects the flow information of the hydraulic fluid and transmits the flow information to the controller in the form of an electrical signal, when the set value is reached, the controller sends a start instruction to the motor, so that the output end of the motor drives the first screw to rotate, thereby moving the baffle downward, and thus flexibly controlling the oil intake. By starting the motor through the coordinated action of the flow meter and the controller, precise control of the motor start is achieved, improving the automation level and operating efficiency of the equipment, while also ensuring that the equipment starts under appropriate working conditions, reducing unnecessary energy consumption and labor. By flexibly controlling the oil intake, the stroke of the oil cylinder piston can be accurately adjusted, thereby achieving precise control of the bending angle, ensuring the dimensional stability of the product, reducing dimensional deviation and product qualification rate, greatly improving work efficiency, avoiding unnecessary waste of resources and energy loss, and reducing production costs.

[0016] (2) By setting up a sampling box, a second screw, an adjusting handle, a sleeve rod, a push rod and a valve cover, the operator can manually adjust the opening size of the valve cover to control the outflow of the hydraulic oil, avoid excessive leakage of the hydraulic oil due to excessive pressure inside the cylinder body, and through sampling, it is possible to timely detect whether the oil is deteriorating, avoid equipment failure caused by oil deterioration, extend the service life of the equipment, thereby ensuring the stability of the equipment's working efficiency and ensuring the accuracy and quality of the bending process.

[0017] (3) By setting up a pressure gauge, the pressure inside the sampling box can be observed, so that the operator can monitor the pressure in time to avoid overload damage to the equipment due to excessive pressure.

[0018] (4) By setting the assembly block and the mounting hole, it is easier for the operator to fix the cylinder and increase the stability of the cylinder, thereby ensuring the consistency of the bending angle and the dimensional stability of the product.

[0019] (5) By setting up a filter, the presence of impurities can be reduced, the working pressure and oil intake of the cylinder can be more stable, and the working accuracy and stability of the bending machine can be improved. Clean hydraulic oil can reduce noise and vibration in the hydraulic system, help maintain the smooth operation of the system, and improve the working environment.

[0020] (6) By setting up sealing rings and support rings, the movement of the piston can be made smoother, reducing the jamming and shaking caused by uneven friction, and ensuring the working accuracy and stability of the cylinder. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments:

[0026] like Figure 1-3 The new type of bending machine cylinder with a flexible oil inlet control structure shown in the figure includes a cylinder body 15 and an extension chamber 7. The bottom of the cylinder body 15 is threadedly connected to an end cover 16, and the end cover 16 is provided with a sliding groove 25. The internal cavity of the cylinder body 15 is slidably connected to a piston 17, and the piston 17 is slidably connected to the sliding groove 25. The top left side of the cylinder body 15 is connected to an oil inlet pipe 9, and an oil filling hole 22 is provided at the top of the cylinder body 15. A longitudinal inner cavity 20 is provided inside the extension chamber 7. The two ends of the oil inlet pipe 9 are respectively connected to the oil filling hole 22 and the longitudinal inner cavity 20. The extension chamber 7 is connected to a connecting pipe. 4. The connecting pipe 4 is connected to the flow meter 3. The extension chamber 7 is slidably connected to the baffle 6. The baffle 6 and the connecting pipe 4 cooperate with each other. When the baffle 6 completely blocks the connecting pipe, the oil inlet can be blocked, thereby controlling the oil inlet amount. The top of the baffle 6 is connected to the extension plate 5. The top of the extension chamber 7 is connected to the bracket 2. The bracket 2 is rotatably connected to the first screw 19. The top of the bracket 2 is connected to the motor 1. The output end of the motor 1 is connected to the first screw 19. The extension plate 5 is threadedly connected to the first screw 19. The bracket 2 is connected to the guide rod 18. The extension plate 5 is slidably connected to the guide rod 18. The extension chamber 7 is connected to the controller 8. The flow meter 3 establishes a signal connection with the controller 8. When the flow meter 3 detects the flow information of the hydraulic fluid and transmits the flow information to the controller 8 in the form of an electrical signal, when the set value is reached, the controller 8 sends a start instruction to the motor 1. After starting the motor 1, the output end of the motor 1 drives the first screw 19 to rotate, thereby moving the extension plate downward, and the baffle 6 moves downward accordingly, so that the baffle 6 completely blocks the connecting pipe 4, thereby controlling the oil intake. The motor 1 is started by the coordinated action of the flow meter 3 and the controller 8, thereby achieving precise control of the start of the motor 1.

[0027] like Figure 3 As shown, the left side of the oil cylinder body 15 is connected to the sampling box 12, which is rotatably connected to the second screw 27. The end of the second screw 27 away from the oil cylinder body 15 is connected to the adjustment handle 11. The sampling box 12 is slidably connected to the sleeve rod 26, which is threadedly connected to the second screw 27. The bottom of the sleeve rod 26 is rotatably connected to the push rod 28. The oil cylinder body 15 is rotatably connected to the valve cover 29, which is rotatably connected to the other end of the push rod 28. By rotating the adjustment handle 11, the second screw 27 rotates accordingly, and the sleeve rod 26 moves, and the push rod 28 moves accordingly, driving the valve cover 29 to rotate to the right, thereby allowing hydraulic oil to enter the sampling box 12.

[0028] like Figure 1-2 As shown, a pressure gauge 10 is connected to the top of the sampling box 12, and the pressure inside the sampling box 12 can be observed through the pressure gauge 10. The outer wall of the cylinder body 15 is connected to an assembly block 13, and the assembly block 13 is provided with a plurality of mounting holes 14, through which the cylinder body 15 can be fixed to the bending machine. A filter screen 21 is connected to the side wall of the oil filling hole 22, and the presence of impurities can be reduced by the filter screen 21. The piston 17 is connected to a sealing ring 23, which effectively prevents the hydraulic oil from leaking out of the gap between the piston 17 and the cylinder barrel. This ensures that the hydraulic system can maintain a stable pressure and ensures the normal operation of equipment such as the bending machine. The piston 17 is connected to a support ring 24, which effectively reduces the shaking amplitude of the piston 17 in the cylinder barrel.

[0029] The specific implementation process is as follows:

[0030] During use, the flow rate of the hydraulic fluid is detected by the flowmeter 3 and transmitted to the controller 8 in the form of an electrical signal. When the set value is reached, the controller 8 sends a start command to the motor 1. After starting the motor 1, the output end of the motor 1 drives the first screw 19 to rotate, thereby moving the extension plate downward, and the baffle 6 moves downward accordingly, so that the baffle 6 completely covers the connecting pipe 4, thereby controlling the amount of oil entering. When the hydraulic oil inside the cylinder body 15 needs to be extracted and tested, the test tube to be sampled is connected to the sampling box 12, and then the adjustment handle 11 is rotated, causing the second screw 27 to rotate accordingly. At this time, the sleeve rod 26 moves, and the push rod 28 moves accordingly, driving the valve cover 29 to rotate to the right, allowing the hydraulic oil to enter the sampling box 12. When the interior of the cylinder body 15 needs to be inspected, the end cap 16 is twisted to completely separate it from the cylinder body 15, and then the cylinder can be opened and its interior can be inspected.

[0031] The above description is merely an embodiment of the present invention, and the commonly known specific technical solutions and / or features of the solution are not described in detail here. It should be noted that for those skilled in the art, without departing from the technical solution of the present invention, several variations and improvements can be made, which should also be considered as the scope of protection of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection claimed in this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
