Description

Technical Field

[0001] This invention relates to the field of real-time measuring devices for forging presses, and in particular to a real-time part size detection device for forging presses. Background Technology

[0002] Forging presses are equipment used for cold working of metals and machinery; they only change the external shape of the metal. Forging presses include plate rolling machines, shearing machines, punching machines, pressure presses, hydraulic presses, oil presses, bending machines, etc. When forging parts, it is usually necessary to monitor the dimensions of the parts in real time to ensure that the processed parts meet the dimensional standards and guarantee processing accuracy. Existing technologies for online measurement of forging dimensions can be divided into direct measurement methods, laser beam projection methods, and CCD image measurement methods, etc.

[0003] However, forging of metal parts is usually carried out in a high-temperature environment. Forgings in a hot-light state not only have extremely high temperatures, but also emit visible light. Therefore, direct measurement methods that involve direct contact with the parts are not suitable. Laser beam projection can only be used during the forging process or when the forging is removed from the forging press. Moreover, it cannot output the two-dimensional contour of the forging in the horizontal section, and the coaxiality and straightness of the forging cannot be measured. CCD image measurement is affected by the high temperature generated by the parts, resulting in unstable measurements. In addition, CCD is limited by the number of pixels, so its overall measurement accuracy of forging dimensions is insufficient. Furthermore, the laser beam projector and CCD camera are used at high temperatures for a long time, which will also affect their service life.

[0004] Therefore, there is an urgent need to design a real-time part size detection device for forging presses that can solve the above problems. Summary of the Invention

[0010] Preferably, a trapezoidal block is provided on the side wall of the L-shaped limiting block, and a trapezoidal pushing block is provided on the side wall of the forging press body, wherein the trapezoidal block and the trapezoidal pushing block are structurally compatible.

[0011] Preferably, the circulating heat dissipation assembly includes a mounting plate, a booster pipe, and a mounting tube. The mounting plate is disposed on the top of the trapezoidal push block. A one-way valve is disposed at each end of the mounting tube. The booster pipe is connected to the mounting tube and is vertically disposed on the top of the mounting plate. A piston is slidably connected inside the wall of the booster pipe. A pressure rod is disposed at the bottom of the piston. The bottom of the pressure rod is fixedly connected to the top of the mounting box.

[0012] Preferably, the sliding rod is provided with two heat-conducting pipes, which are respectively connected to both ends of the mounting tube, and the bottom of both heat-conducting pipes extends beyond the bottom of the sliding rod.

[0013] Preferably, the replaceable contact assembly includes a contact block, a heat insulation plate, and two limiting plates. The heat insulation plate is disposed at the bottom of the sliding rod, and the two limiting plates are spaced apart at the bottom of the heat insulation plate. The top of the contact block is provided with two slots, each slot corresponding to a limiting plate, and each limiting plate engaging with its corresponding slot. A spiral cooling pipe is provided inside the contact block, and both ends of the spiral cooling pipe are connected to a heat-conducting pipe.

[0014] Preferably, each end of the contact block is provided with a fastening bolt, and each fastening bolt is threadedly connected to a limiting plate.

[0015] Preferably, the automatic detection component includes a controller, a mounting column, a sliding plate, and a camera.

[0016] Preferably, the forging press body and the camera are both electrically connected to the controller.

[0017] The beneficial effects of this invention are:

[0018] Firstly, with the help of precision measuring components, this invention can measure the real-time thickness of the part after each stamping by the forging press body. This allows the forging press body to adjust the impact force on the part in the next stamping based on the change in the part's thickness, thereby forging the part into the size that meets the design requirements.

[0019] Secondly, in this invention, the automatic detection component can monitor the thickness change of the part in real time, and then adjust the impact force of the forging press body through the controller;

[0020] Thirdly, in this invention, the replaceable contact component allows for the individual replacement of the contact block. Since the contact block is subjected to mutual impact with the part placement table for a long time, it will wear out. Replacing the worn contact block individually can ensure the accuracy of the part size detection and avoid measurement errors.

[0021] Fourth, the circulating heat dissipation component can dissipate heat from the sliding rod and the contact block, preventing the contact block and the sliding rod from deforming due to heat, and further ensuring the accuracy of the measurement.

[0022] Fifth, during the forging process, the trapezoidal push block will not come into contact with the trapezoidal block. However, after a part is forged, the output end of the forging press will be reset under the action of the controller, causing the trapezoidal block and the trapezoidal push block to come into contact with each other. This will cause the L-shaped limit block to disengage from the sliding rod. At this time, the sliding rod will be pushed vertically downward under the action of the compression spring, so that the sliding rod can be automatically reset, so as to facilitate continuous real-time detection of the subsequent parts.

[0035] To make the above-mentioned objects, features, and advantages of the present invention more readily understood, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0036] like Figure 1-11 As shown, the present invention provides a real-time part size detection device for a forging press, including a forging press body 1, a part placement platform 4 below the forging press body 1, two semi-circular clamping plates 10 sleeved on the output end of the forging press body 1, the two semi-circular clamping plates 10 being fixedly connected by bolts, a mounting box 3 being provided beside the semi-circular clamping plates 10, a precision measuring component being provided inside the mounting box 3, a replaceable contact component being provided at the bottom of the precision measuring component, a circulating heat dissipation component being provided above the mounting box 3, and an automatic detection component being provided beside the forging press body 1;

[0037] The precision measuring component includes a support rod 12, a sliding rod 13, an L-shaped limiting block 17, and a scale 24. One end of the support rod 12 is connected to the mounting box 3, and the other end of the support rod 12 is fixedly connected to a semi-circular clamping piece 10. The sliding rod 13 slides in the mounting box 3 in the vertical direction. The L-shaped limiting block 17 is rotatably connected to the top of the support rod 12. The sliding rod 13 has a first one-way toothed groove 41 at one end near the L-shaped limiting block 17, and the L-shaped limiting block 17 has a second one-way toothed groove 42 at one side near the sliding rod 13. The first one-way toothed groove 41 and the second one-way toothed groove 42 are structurally matched. The sliding rod 13 and the L-shaped limiting block 17 are unidirectionally connected through the first one-way toothed groove 41 and the second one-way toothed groove 42. The scale 24 is fixedly connected to the side wall of the sliding rod 13.

[0038] In this invention, the precision measuring component can measure the real-time thickness of the part after each stamping by the forging press, so that the forging press can adjust the impact force on the part in the next stamping based on the thickness change, thereby ensuring that the part can be forged into the size required by the design. The automatic detection component can monitor the thickness change of the part in real time, and can adjust the impact force of the forging press through the controller. The replaceable contact component can replace the contact block 14 individually. Since the contact block 14 will wear out due to long-term impact with the part placement table 4, replacing the worn contact block 14 individually can ensure the accuracy of the part size detection and avoid measurement errors. The circulating heat dissipation component can dissipate heat from the sliding rod 13 and the contact block 14 to prevent the contact block 14 and the sliding rod 13 from deforming due to heat, further ensuring the accuracy of the measurement.

[0039] Furthermore, in the above technical solution, the precision measuring component also includes a mounting bracket 8, a compression spring 15, and a return spring 18. The mounting bracket 8 is disposed on the top of the mounting box 3. One end of the compression spring 15 is fixedly connected to the mounting bracket 8, and the other end of the compression spring 15 is fixedly connected to the top of the sliding rod 13. One end of the return spring 18 is fixedly connected to the inner wall of the mounting box 3, and the other end of the return spring 18 is fixedly connected to the side wall of the L-shaped limiting block 17.

[0040] Each time the forging press body 1 forges a part, it drives the sliding rod 13 to move downwards, causing the contact block 14 at the bottom of the sliding rod 13 to impact the part placement table 4. This causes the sliding rod 13 to move vertically upwards and cannot move downwards. However, due to the unidirectional transmission connection between the first one-way tooth groove 41 and the second one-way tooth groove 42, the sliding rod 13 can only move vertically upwards under the action of the L-shaped limiting block 17. The compression spring 15 can apply vertical downward pressure to the sliding rod 13, preventing the sliding rod 13 from moving excessively upwards due to inertia after impacting the part placement table 4. This ensures that the sliding distance of the sliding rod 13 each time it slides is consistent with the thickness of the compressed part, thereby ensuring the accuracy of the part thickness measurement.

[0041] Furthermore, in the above technical solution, a trapezoidal block 21 is provided on the side wall of the L-shaped limiting block 17, and a trapezoidal pushing block 16 is provided on the side wall of the forging press body 1, wherein the trapezoidal block 21 and the trapezoidal pushing block 16 are structurally matched.

[0042] During the forging process, the trapezoidal push block 16 of the forging press body 1 will not come into contact with the trapezoidal block 21. When a part is forged, the forging press body 1 will drive the output end of the forging press to reset under the action of the controller, so that the trapezoidal block 21 and the trapezoidal push block 16 come into contact with each other, thereby causing the L-shaped limit block 17 to disengage from the sliding rod 13. At this time, the sliding rod 13 is pushed vertically downward under the action of the compression spring 15, so that the sliding rod 13 can automatically reset, so as to continuously monitor the subsequent parts in real time.

[0043] Furthermore, in the above technical solution, an L-shaped stop 25 is provided on the top of the mounting box 3, a baffle 34 is provided on the sliding rod 13, the baffle 34 cooperates with the L-shaped stop 25, a reinforcing plate 23 is provided on the outer wall of the sliding rod 13, a pointer 19 is provided on the side wall of the forging press body 1, the automatic detection component includes a controller, a mounting column 5, a sliding plate 6 and a camera 7, the mounting column 5 is located on the side of the forging press body 1, the sliding plate 6 is slidably connected to the mounting column 5, an electric cylinder 40 is provided inside the mounting column 5, the output end of the electric cylinder 40 is fixedly connected to the bottom of the sliding plate 6, and the camera 7 is located on the side wall of the mounting plate 26;

[0044] The electric cylinder 40 drives the camera 7 to rise and fall via the sliding plate 6, so that the camera 7 and the pointer 19 are at the same height. During the real-time detection of the part size, the camera 7 can monitor the real-time position of the scale 24 and transmit the size data to the controller, so that the controller can adjust the forging press body 1. The camera 7 is located away from the part to avoid the camera 7 being in a high-temperature environment for a long time, which not only ensures the accuracy of the detection, but also extends the service life of the camera 7.

[0045] Furthermore, in the above technical solution, the circulating heat dissipation assembly includes a mounting plate 26, a pressure boosting pipe 30, and a mounting pipe 9. The mounting plate 26 is disposed on the top of the trapezoidal push block 16. A one-way valve 31 is disposed at each end of the mounting pipe 9. The pressure boosting pipe 30 is connected to the mounting pipe 9. The pressure boosting pipe 30 is vertically disposed on the top of the mounting plate 26. A piston 32 is slidably connected inside the pipe wall of the pressure boosting pipe 30. A pressure rod 33 is disposed at the bottom of the piston 32. The bottom of the pressure rod 33 is fixedly connected to the top of the mounting box 3. Two heat conduction pipes 20 are disposed inside the sliding rod 13. The two heat conduction pipes 20 are respectively connected to the two ends of the mounting pipe 9. The bottoms of the two heat conduction pipes 20 extend beyond the bottom of the sliding rod 13.

[0046] As the forging press body 1 moves, it drives the mounting box 3 to reciprocate in the vertical direction. This, in turn, drives the piston 32 to reciprocate in the pressure pipe 30 via the pressure rod 33. Since the two heat pipes 20 are filled with coolant and the mounting pipe 9 is equipped with two one-way valves 31, when the piston 32 reciprocates in the pressure pipe 30, the coolant will flow in from one side of the mounting pipe 9 and out from the other side, thus allowing the coolant in the two heat pipes 20 to circulate and dissipate heat from the sliding rod 13.

[0047] Furthermore, in the above technical solution, the replaceable contact assembly includes a contact block 14, a heat insulation plate 37, and two limiting plates 36. The heat insulation plate 37 is disposed at the bottom of the sliding rod 13, and the two limiting plates 36 are spaced apart at the bottom of the heat insulation plate 37. The top of the contact block 14 is provided with two slots 38, each slot 38 corresponding to a limiting plate 36, and each limiting plate 36 engaging with the corresponding slot 38. A spiral cooling pipe 35 is provided inside the contact block 14, and both ends of the spiral cooling pipe 35 are respectively connected to a heat-conducting pipe 20. A fastening bolt 39 is provided at both ends of the contact block 14, and each fastening bolt 39 is threadedly connected to a limiting plate 36.

[0048] When the contact block 14 needs to be replaced after wear, first remove the two fastening bolts 39, and then the contact block 14 can be removed and replaced. By providing a spiral cooling pipe 35 inside the contact block 14, the coolant can circulate inside the contact block 14 to dissipate heat and prevent the contact block 14 from deforming due to heat caused by prolonged contact with the part placement platform 4.

[0049] Furthermore, in the above technical solution, the forging press body 1 and the camera 7 are both electrically connected to the controller; the controller is a C8051F020 microcontroller, and the controller adjusts the forging pressure of the forging press body 1 by changing the size of the part.

[0050] Working Principle: In this invention, the precision measuring component can measure the real-time thickness of the part after each stamping by the forging press body 1. This allows the forging press body 1 to adjust the impact force on the part in the next stamping based on the thickness change, thereby ensuring that the part is forged to the size required by the design. The automatic detection component can monitor the thickness change of the part in real time and adjust the impact force of the forging press body 1 through the controller. The replaceable contact component can replace the contact block 14 individually. Since the contact block 14 is subjected to mutual impact with the part placement table 4 for a long time, it will wear out. Replacing the worn contact block 14 individually can ensure the accuracy of the part size detection and avoid measurement errors. The circulating heat dissipation component can dissipate heat from the sliding rod 13 and the contact block 14 to prevent the contact block 14 and the sliding rod 13 from deforming due to heat, further ensuring the accuracy of the measurement.

[0051] Each time the forging press body 1 forges a part, it drives the sliding rod 13 to move downwards, causing the contact block 14 at the bottom of the sliding rod 13 to impact the part placement table 4. This causes the sliding rod 13 to move vertically upwards and cannot move downwards. However, due to the unidirectional transmission connection between the first one-way tooth groove 41 and the second one-way tooth groove 42, the sliding rod 13 can only move vertically upwards under the action of the L-shaped limiting block 17. The compression spring 15 can apply vertical downward pressure to the sliding rod 13, preventing the sliding rod 13 from moving excessively upwards due to inertia after impacting the part placement table 4. This ensures that the sliding distance of the sliding rod 13 each time it slides is consistent with the thickness of the compressed part, thereby ensuring the accuracy of the part thickness measurement.

[0052] During the forging process, the trapezoidal push block 16 of the forging press body 1 will not come into contact with the trapezoidal block 21. When a part is forged, the output end of the forging press body 1 will be reset under the action of the controller, so that the trapezoidal block 21 and the trapezoidal push block 16 come into contact with each other, thereby causing the L-shaped limit block 17 to disengage from the sliding rod 13. At this time, the sliding rod 13 is pushed vertically downward under the action of the compression spring 15, so that the sliding rod 13 can be automatically reset, so as to continuously monitor the subsequent parts in real time.

[0053] The electric cylinder 40 drives the camera 7 to rise and fall via the sliding plate 6, so that the camera 7 and the pointer 19 are at the same height. During the real-time detection of the part size, the camera 7 can monitor the real-time position of the scale 24 and transmit the size data to the controller, so that the controller can adjust the forging press body 1. The camera 7 is located away from the part to avoid the camera 7 being in a high-temperature environment for a long time, which not only ensures the accuracy of the detection, but also extends the service life of the camera 7.

[0054] As the forging press body 1 moves, it drives the mounting box 3 to reciprocate in the vertical direction. This, in turn, drives the piston 32 to reciprocate in the pressure pipe 30 via the pressure rod 33. Since the two heat pipes 20 are filled with coolant and the mounting pipe 9 is equipped with two one-way valves 31, when the piston 32 reciprocates in the pressure pipe 30, the coolant will flow in from one side of the mounting pipe 9 and out from the other side, thus allowing the coolant in the two heat pipes 20 to circulate and dissipate heat from the sliding rod 13.

[0055] When the contact block 14 needs to be replaced after wear, first remove the two fastening bolts 39, and then the contact block 14 can be removed and replaced. By providing a spiral cooling pipe 35 inside the contact block 14, the coolant can circulate inside the contact block 14 to dissipate heat and prevent the contact block 14 from deforming due to heat caused by prolonged contact with the part placement platform 4.

[0056] The above-described embodiments are merely one implementation of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the scope of protection of the present invention. Therefore, the scope of protection of this invention should be determined by the appended claims.
