A sliding table type descaling machine and automatic forging production line

Abstract

This application discloses a sliding descaling machine and an automatic forging production line. A slide table supported by longitudinal beams drives a support frame, which carries and fixes the pre-forging billet to be descaled. This ensures that the pre-forging billet maintains a stable posture and a relatively stable position relative to the support frame when passing through the spray area formed by nozzles and under the impact of high-pressure water jets. This facilitates the gripping of the robot during final forging, and ensures that the pre-forging billet has a set position and posture during gripping. Thus, the pre-forging billet can be automatically gripped by the robot and placed into the final forging mold, thereby forming an automated forging production line. This achieves automated production of forgings and has the advantages of good durability, strong adaptability to harsh working conditions, high reliability, and high stability.

Description

Technical Field

[0001] This application relates to the field of forging equipment technology, specifically a slide-table descaling machine and an automatic forging production line. Background Technology

[0002] A forging production line is a streamlined process for mass-producing forged parts. It typically includes steps such as billet preparation or pre-forging and final forging. Because forging, especially for ferrous metals, requires heating to a set temperature during the forging process, oxide scale will form on the billet or pre-forged billet. This oxide scale needs to be removed (also called descaling) when entering the final forging step to ensure the surface quality of the final forging. Currently, methods for removing this type of oxide scale include manual brushing and high-pressure water jet descaling. Among them, high-pressure water jet descaling is gradually becoming more widely used due to its high efficiency and labor-saving advantages. However, it has the disadvantage of not being able to maintain the stability of the billet's posture during the descaling process. In automated forging production lines, especially those with pre-forging steps, the pre-forged billet has a pre-defined external shape. When it enters the final forging die, it needs to be grasped by the robot arm in a posture that conforms to the final forging die to be accurately placed into the die. As the billet in the existing descaling equipment may flip, roll, or undergo other random displacements during the descaling process, it becomes difficult for the robot arm in subsequent steps to accurately grasp the pre-forged billet. Manual assistance is required for placement, making full automation impossible. Alternatively, an additional vision system may be needed to coordinate with the robot arm's movements. However, due to the harsh working conditions in forging production lines, vision systems are prone to damage and are costly. Therefore, it is necessary to solve the above problems. Summary of the Invention

[0003] The purpose of this application is to provide a sliding table type descaling machine and an automatic forging production line to solve the problems in the prior art.

[0004] To achieve the above objectives, this application provides the following technical solution: a sliding table descaling machine, comprising a plurality of nozzles 307 arranged opposite to each other and spaced apart, a high-pressure pump 306 for pressurizing water in a water tank 304 and pumping it to the nozzles 307, and a set of parallel longitudinal beams 302 arranged at intervals and a sliding table 309 slidably arranged along the longitudinal beams 302. The spraying area formed by the nozzles 307 is located inside the longitudinal beams 302. A support frame 313 for supporting a pre-forged billet 7 is detachably mounted on the sliding table 309. When the support frame 313 passes through the spraying area with the sliding table 309, the water jets sprayed from the nozzles 307 peel off the oxide scale on the pre-forged billet 7, and the support frame 313 is used to keep the position and orientation of the pre-forged billet 7 within a set envelope range after passing through the spraying area.

[0005] Furthermore, the material support frame 313 is a through frame structure and the through direction is parallel to the axial direction of the spray hole of the nozzle 307, so that the water jet sprayed by the nozzle 307 can be sprayed onto the surface of the pre-forged billet 7.

[0006] Furthermore, the top of the material support frame 313 is open and spaced apart with multiple positioning plates 315. The positioning plates 315 have U-shaped slots that are adapted to the cross-section of the pre-forged billet 7. All the U-shaped slots on the positioning plates 315 form a positioning cavity 318 for supporting and positioning the pre-forged billet 7. The positioning cavity 318 has a set gap with the side of the pre-forged billet 7 to allow the pre-forged billet 7 to swing within the gap range. The space area defined by the positioning cavity 318 is the envelope.

[0007] Furthermore, the positioning plate 315 also has a notch 316 formed on the wall of the U-shaped bayonet, the notch 316 being used to reduce the contact area between the positioning plate 315 and the pre-forged billet 7.

[0008] Furthermore, the outer end of the positioning plate 315 is also provided with a side plate 317, which is parallel to the corresponding side wall of the material support frame 313 and is used to guide the water jet reflected from the pre-forged billet 7 into the interior of the material support frame 313.

[0009] Furthermore, the slide table 309 includes a movable seat 3091 guided by the longitudinal beam 302, a support plate 3092 mounted on the movable seat 3091, and a support leg 314 provided at the bottom of the material support frame 313 for detachable connection with the support plate 3092.

[0010] Furthermore, the support plate 3092 is a Z-shaped structure consisting of a bottom plate segment 3093, a vertical plate segment 3094, and a top plate segment 3095 connected in sequence. The support leg 314 is connected to the bottom plate segment 3093, and the top plate segment 3095 is connected to the movable seat 3091.

[0011] Furthermore, an inner support beam 319 is provided on the inner side of the longitudinal beam 302, and the vertical plate section 3094 is located in the gap between the longitudinal beam 302 and the inner support beam 319. Sealing plates 320 are provided at both ends of the longitudinal beam 302, and the two ends of the inner support beam 319 are fixedly connected to the sealing plates 320. A guide plate 321 is provided at the bottom of the longitudinal beam 302, a spray box 301 is provided above the longitudinal beam 302, and a filter box 303 is provided below the longitudinal beam 302. The nozzles 307 correspond respectively to the spray box 301 and the filter box 303. The nozzles 307, which are arranged in a plurality of spray boxes 301, have spray directions opposite to those of the nozzles 307 located above the filter box 303, and the nozzles 307, which are arranged vertically opposite to each other, have a gap between their orifices that allows the pre-forged billet 7 to pass through. The side wall of the longitudinal beam 302, the sealing plate 320, and the guide plate 321 form a guide groove with both ends closed, which is used to guide the water jet sprayed onto the pre-forged billet 7 and the oxide scale peeled off from the pre-forged billet 7 into the filter box 303. The clean water output end of the filter box 303 is connected to the water tank 304.

[0012] Furthermore, the sliding descaling machine also includes a linear guide 312 disposed on the outer wall of the longitudinal beam 302 and extending longitudinally along the longitudinal beam 302. The movable seat 3091 is slidably supported by the linear guide 312. At least one of the outer walls of the longitudinal beam 302 is also provided with a rack 310 parallel to the linear guide 312. A motor 308 is mounted on the movable seat 3091 on the same side as the rack 310. A gear 311 is disposed on the output shaft of the motor 308 and meshes with the rack 310 to drive the material support frame 313 to reciprocate along the linear guide 312 so that the material support frame 313 passes through the spraying area.

[0013] An automated forging production line includes a pre-forging device 1, a first robot 2 for removing a pre-forged billet 7 from the pre-forging device, a final forging device 5, a second robot 4 for feeding material into the final forging device 5, and a third robot 6 for removing the final forging from the final forging device 5, arranged in sequence. It also includes the aforementioned sliding descaling machine 3. The first robot 2 is further used to place the pre-forged billet 7 into the material receiving rack 313, and the second robot 4 is further used to grab the descaled pre-forged billet 7 from the material receiving rack 313.

[0014] The beneficial technical effects of this application are as follows: The sliding table descaling machine provided by this application uses a sliding table supported by a longitudinal beam to drive a material support frame. The material support frame carries and positions the pre-forged billet to be descaled, so that when the pre-forged billet passes through the spray area formed by nozzles, it can maintain a stable posture and a relatively stable position relative to the material support frame under the impact of high-pressure water jet. This facilitates the gripping of the robot during final forging, and ensures that the pre-forged billet has a set position and posture when gripped by the robot. Thus, the pre-forged billet can be automatically gripped by the robot and placed into the final forging mold, thereby forming an automated forging production line and realizing automated forging production of forgings. It has the advantages of good durability, strong adaptability to harsh working conditions, high reliability and stability. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] Please see Figure 1-7 This application provides a sliding table type descaling machine, including a plurality of nozzles 307 arranged opposite to each other and spaced apart, a high-pressure pump 306 for pressurizing water in a water tank 304 and pumping it to the nozzles 307, a set of parallel longitudinal beams 302 arranged at intervals, and a sliding table 309 slidably arranged along the longitudinal beams 302. The spraying area formed by the nozzles 307 is located inside the longitudinal beams 302. A support frame 313 for supporting a pre-forged billet 7 is detachably mounted on the sliding table 309. When the support frame 313 passes through the spraying area with the sliding table 309, the water jets sprayed in the nozzles 307 peel off the oxide scale on the pre-forged billet 7, and the support frame 313 is used to keep the position and posture of the pre-forged billet 7 within a set envelope range after passing through the spraying area.

[0025] According to the structure provided in this embodiment, the sliding descaling machine 3 provided in this application drives the material support frame 313 by setting a sliding table 309 supported by a longitudinal beam 302. The material support frame 313 carries and positions the pre-forged billet 7 to be descaled, so that when the pre-forged billet 7 passes through the spray area formed by the nozzle 307, it can still maintain a stable posture and a relatively stable position relative to the material support frame under the impact of the high-pressure water jet. This facilitates the gripping of the robot during final forging, and ensures that the pre-forged billet has a set position and posture when the robot grips it. Thus, the pre-forged billet can be automatically gripped by the robot and placed into the final forging mold, thereby forming an automated forging production line and realizing automated forging production of forgings. It has the advantages of good durability, strong adaptability to harsh working conditions, high reliability and stability.

[0026] In another embodiment of this application, please refer to [the relevant document / reference]. Figure 1 and Figure 7The support frame 313 is a through-frame structure with its through-path parallel to the axial direction of the nozzle 307's spray hole, so that the water jet ejected by the nozzle 307 can be sprayed onto the surface of the pre-forged billet 7. In this embodiment, the support frame 313 is a through-frame structure with both the top and bottom open. Thus, the nozzle 307 located below the support frame 313 has its spray hole facing upwards, allowing the water jet to be smoothly sprayed from below onto the surface of the pre-forged billet 7. The nozzle 307 located above the support frame 313 has its spray hole facing downwards, allowing the water jet to also be smoothly sprayed onto the surface of the pre-forged billet 7. The water jet is sprayed smoothly from above onto the surface of the pre-forged billet 7. As the support frame 313 passes through the spraying area, the oxide scale on the surface of the pre-forged billet 7 can be removed. It is understandable that since the pre-forged billet 7 has a draft angle, that is, the small ends of the side walls of the pre-forged billet 7 are all facing the direction of the water jet, they can all be impacted by the water jet. At the same time, the number and arrangement of the nozzles 307 can be set according to the maximum envelope volume of the pre-forged billet 7, so that the entire surface of the pre-forged billet 7 can be impacted by the water jet to achieve a highly efficient descaling effect.

[0027] In another embodiment of this application, please refer to [the relevant document / reference]. Figure 1 and Figure 7 The top of the support frame 313 is open and spaced apart with multiple positioning plates 315. The surface of the positioning plate 315 is parallel to the axial direction of the injection hole of the nozzle 307. The positioning plate 315 has a U-shaped slot that matches the cross section of the pre-forged billet 7. The U-shaped slots on all the positioning plates 315 form a positioning cavity 318 for supporting and positioning the pre-forged billet 7. The positioning cavity 318 has a set gap with the side of the pre-forged billet 7 to allow the pre-forged billet 7 to swing within the gap range. The space area defined by the positioning cavity 318 is an envelope.

[0028] According to the structure provided in this embodiment, the bottom of the U-shaped bayonet is used to support the pre-forged billet 7, and the opposite side walls are used to limit the side of the pre-forged billet 7. Since the cross-sections at both ends of the pre-forged billet 7 are smaller than the cross-section at the middle, the side walls of the U-shaped bayonet of the positioning plate 315 located at both ends of the pre-forged billet 7 also have the function of limiting the position of both ends of the pre-forged billet 7. Thus, under the action of the weight of the pre-forged billet 7 itself, the pre-forged billet 7 is restricted and positioned in the positioning cavity 318 to achieve relative positioning by shaking within an allowable range. At the same time, since the pre-forged billet 7 is allowed to shake within the gap range, under the impact of the water jet sprayed from the nozzle 307, the pre-forged billet 7 can move relative to the positioning plate 315 to a limited extent, avoiding the positioning plate 315 and the pre-forged billet 7 having a fixed contact position, which would cause oxide scale residue at the contact position, thereby more completely removing the oxide scale on the surface of the pre-forged billet 7. Thus, after the pre-forged billet 7 passes through the nozzle 307 with the support frame 313, its position and orientation will remain within the envelope space formed by the positioning cavity 318, achieving positioning within the positioning cavity 318. It will then be transported by the support frame 313 to the designated position and retrieved by the robot in the subsequent step (such as by the second robot 4 described later). It is understood that the size of this gap can be flexibly set by those skilled in the art based on the contour of the pre-forged billet 7, the size of the final forging die cavity, and the draft angle.

[0029] In another embodiment of this application, please refer to [the relevant document / reference]. Figure 1 and Figure 7 The positioning plate 315 also has a notch 316 formed on the wall of the U-shaped bayonet. The notch 316 is used to reduce the contact area between the positioning plate 315 and the pre-forged billet 7. In this way, on the one hand, the resistance of the pre-forged billet 7 when it shakes in the positioning cavity 318 is reduced, which is conducive to the pre-forged billet 7 moving within a limited range relative to the positioning plate 315 in the positioning cavity 318 under the action of the water jet from the nozzle 307. The positioning plate 315 on both sides of the notch 316 can also play a role in locally scraping off the oxide scale, which is further conducive to completely cleaning the oxide scale on the surface of the pre-forged billet 7. On the other hand, the notch 316 can also reduce the heat conducted from the pre-forged billet 7 to the positioning plate 315 while ensuring the supporting and limiting function, which is conducive to reducing the deformation of the positioning plate 315 and ensuring the service life of the positioning plate 315.

[0030] In another embodiment of this application, please refer to [the relevant document / reference]. Figure 1 and Figure 7 The outer end of the positioning plate 315 is also provided with a side plate 317. The side plate 317 is parallel to the corresponding side wall of the material support frame 313 and is used to guide the water jet reflected from the pre-forged billet 7 into the material support frame 313. In this way, water jet splashing is avoided, water can be recycled and reused, and the workshop can be kept clean.

[0031] In another embodiment of this application, please refer to [the relevant document / reference]. Figure 1 and Figure 7 The slide table 309 includes a movable seat 3091 guided by a longitudinal beam 302, a support plate 3092 mounted on the movable seat 3091, and a support leg 314 at the bottom of the material support frame 313 for detachable connection with the support plate 3092. In this way, the material support frame 313 can be designed to fit the contour of the pre-forged billet 7, while the slide table 309 remains unchanged, which is beneficial to improving the adaptability of this slide table descaling machine and also has the advantage of convenient replacement of the material support frame 313. It is understood that the support leg 314 is detachably connected to the support plate 3092 by fasteners.

[0032] In another embodiment of this application, please refer to [the relevant document / reference]. Figure 1 and Figure 7 The support plate 3092 is a Z-shaped structure consisting of a bottom plate section 3093, a vertical plate section 3094, and a top plate section 3095 connected in sequence. The support leg 314 is connected to the bottom plate section 3093, and the top plate section 3095 is connected to the movable seat 3091. In this embodiment, the support plate 3092 and the movable seat 3091 are both arranged in pairs, and the bottom plate section 3093 is lower than the top plate section 3095. This can effectively lower the center of gravity of the material support frame 313 and provide stable sliding support for the material support frame 313, which is beneficial to improving the stability of the material support frame 313 as it moves with the slide table 309.

[0033] In another embodiment of this application, please refer to [the relevant document / reference]. Figure 1 and Figure 7An inner support beam 319 is also provided on the inner side of the longitudinal beam 302. The vertical plate section 3094 is located in the gap between the longitudinal beam 302 and the inner support beam 319. Sealing plates 320 are provided at both ends of the longitudinal beam 302. The two ends of the inner support beam 319 are fixedly connected to the sealing plates 320. In this embodiment, the longitudinal beam 302 is made of sheet metal and has a folded edge section 3021 formed at the upper end facing the inner support beam 319, which helps to improve the strength and rigidity of the longitudinal beam 302. A guide plate 321 is provided at the bottom of the longitudinal beam 302. A spray box 301 is provided above the longitudinal beam 302. A filter box 303 is provided below the longitudinal beam 302. Multiple nozzles 307 are respectively provided inside the spray box 301 and above the filter box 303. The spray direction of the nozzles 307 in the spray box 301 is the same as that of the nozzles in the filter box 303. The nozzles 307 above 3 have opposite spray directions and have a gap between their orifices that allows the pre-forged billet 7 to pass through. The sidewall of the longitudinal beam 302, the sealing plate 320, and the guide plate 321 form a guide groove with closed ends, which is used to guide the water jet sprayed onto the pre-forged billet 7 and the oxide scale peeled off from the pre-forged billet 7 into the filter box 303. The clean water output end of the filter box 303 is connected to the water tank 304. In this embodiment, an oxide scale output roller 305 is also installed on one side of the filter box 303. The oxide scale output roller 305 is a magnetic roller structure to transfer the oxide scale accumulated in the filter box 303 out of the filter box 303. Its specific structure can adopt the existing technology in this field. The installation and fixing method of the nozzles 307 in the spray box 301 and the filter box 303 can also adopt the existing technology.

[0034] According to the structure provided in this embodiment, the longitudinal beam 302 and the inner support beam 319 constitute a composite support structure, which further improves the rigidity and strength of the longitudinal beam 302 and also has the effect of light weight; the interlocking spray box 301 and filter box 303 can effectively prevent water jets and oxide scale splashing, which is conducive to water recycling and prevention of workshop pollution; the guide channel guides the used water and the peeled oxide scale together to the filter box 303 for filtration and then returns it to the water tank 304, realizing water recycling; at the same time, the Z-shaped support plate 3 092, its top plate section 3095 extends outward from above the gap between the longitudinal beam 302 and the inner support beam 319 and connects to the movable seat 3091. The bottom plate section 3093 extends inward from below the gap between the longitudinal beam 302 and the inner support beam 319 to connect with the support leg 314. In this way, the material support frame 313 runs between the inner support beams 319. Therefore, the inner support beams 319 also serve to block splashing water jets and peeled oxide scale, causing the oxide scale to fall into the guide channel and reducing the amount of oxide scale adhering to the inner wall of the longitudinal beam 302. It can be understood that the guide plate 321 is an inclined structure that gradually decreases towards the filter box 303 and has a corresponding opening on the opening side of the filter box 303.

[0035] In another embodiment of this application, please refer to [the relevant document / reference]. Figure 1 and Figure 7 The sliding descaling machine also includes a linear guide 312 installed on the outer wall of the longitudinal beam 302 and extending longitudinally along the longitudinal beam 302. The movable seat 3091 is slidably supported by the linear guide 312. At least one longitudinal beam 302 has a rack 310 parallel to the linear guide 312 installed on its outer wall. A motor 308 is mounted on the movable seat 3091 on the same side as the rack 310. A gear 311 is installed on the output shaft of the motor 308, meshing with the rack 310, to drive the material support frame 313 to reciprocate along the linear guide 312 so that the material support frame 313 passes through the spraying area. Thus, through the guiding and supporting action of the linear guide 312, the movement of the sliding table 309 is kept smooth. At the same time, installing the linear guide 312 on the outer wall of the longitudinal beam 302 also helps to prevent it from being affected by water jets and... Oxide scale contamination helps extend the service life of the linear guide 312 and ensures smooth operation of the slide-type descaling machine. The motor 308 provides the power for the slide 309 to drive the support frame 313 to move the pre-forged billet 7. The motor 308 can be easily controlled by the electrical control system to control the direction and speed of the support frame 313, thereby achieving better efficiency and oxide scale removal effect. For example, the support frame 313 can be moved quickly when it is unloaded and before or after the pre-forged billet 7 enters the spraying area to improve conveying efficiency. When the pre-forged billet 7 enters the spraying area, it can be fed at a set speed to ensure the oxide scale removal effect. Here, the motor 308 is preferably any one of a variable speed motor, a stepper motor, or a servo motor.

[0036] In another embodiment of this application, please refer to [the relevant document / reference]. Figure 1 and Figure 7 This application also provides an automated forging production line, including a pre-forging device 1, a first robot 2 for removing a pre-forged billet 7 from the pre-forging device, a final forging device 5, a second robot 4 for feeding material into the final forging device 5, and a third robot 6 for removing the final forging from the final forging device 5, arranged in sequence. It also includes the aforementioned sliding descaling machine 3. The first robot 2 is also used to place the pre-forged billet 7 on a support rack 313, and the second robot 4 is also used to grab the descaled pre-forged billet 7 from the support rack 313. Since the support rack 313 ensures the relative position and posture stability of the pre-forged billet 7, it is easy for the first robot 2 to place the pre-forged billet 7 in the support rack 313, and it is convenient for the second robot 4 to grab it, which helps to simplify the structure of the second robot 4, reduce costs, and improve efficiency.
