Description

Technical Field

[0001] This utility model relates to the technical field of integrated feeding and unloading machines for forgings, and in particular to a columnar medium and large forging handling equipment. Background Technology

[0002] In modern industrial production, forging is an important method for manufacturing medium and large forgings. It is widely used in many fields such as machinery manufacturing, automobiles, and aerospace. In the forging production process, the feeding and unloading of medium and large forgings are crucial links that directly affect production efficiency and product quality.

[0003] Currently, existing feeding and handling equipment for medium and large forgings faces several problems when handling long, cylindrical forgings. To save heating space, these forgings are typically placed horizontally in the furnace during heating. When removing the heated forging from the furnace and placing it on the forging platform, the extremely high temperature and reduced strength necessitate a vertical clamping method to prevent deformation due to localized stress concentration and surface damage. While clamping forgings inside the furnace can distribute the clamping force over a large area of ​​the cylindrical surface, preventing localized stress concentration that could lead to deformation and surface damage, it also presents a problem: after transferring the forging to the forging platform, it cannot automatically stand the forging upright. Operators often need to continuously adjust the position of the forging using equipment to achieve an upright state. This method is not only difficult to operate and carries a high risk of forging detachment, requiring highly skilled and experienced operators, but also consumes a significant amount of time and energy, severely impacting production efficiency. Therefore, to address these issues, a cylindrical medium-to-large forging handling device is proposed. Utility Model Content

[0004] The technical problem to be solved by this utility model overcomes the existing defects and can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A cylindrical medium-to-large forging handling device includes a feeding and unloading integrated machine. The clamping drive shaft of the feeding and unloading integrated machine is provided with a fixed seat on its outer side, and the fixed seat is in contact with the clamping drive shaft of the feeding and unloading integrated machine. A hydraulic rod is fixedly connected to the bottom left side of the fixed seat, and the hydraulic rod is fixedly connected to the clamping drive shaft of the feeding and unloading integrated machine through a connecting block. A push rod is provided at the bottom right side of the fixed seat, and the other end of the push rod is rotatably connected to a support rod through a rotating shaft. One end of the support rod contacts a clamping block with an arc-shaped end.

[0007] As a further improvement of this utility model, the top front and rear sides of the fixed base are provided with guide shafts, and the guide shafts pass through the fixed base. The guide shafts are slidably connected to the fixed base. A fixing block is fixedly connected to the end of the guide shaft, and the fixing block is fixedly connected to the clamping drive shaft of the feeding and unloading integrated machine.

[0008] As a further improvement of this utility model, the bottom inner side of the fixed base is slidably connected to both the front and rear ends of the fixed base, and the limiting blocks are rotatably connected to the push rod through a rotating shaft.

[0009] As a further improvement of this utility model, a ball bearing is rotatably connected to the outer side of the limiting block, and the ball bearing is symmetrically distributed on the outer side of the limiting block, and the ball bearing is in contact with the fixed seat.

[0010] As a further improvement of this utility model, the angular rotation range of the support rod and the clamping block is 0°-90°, and the top of the support rod is rotatably connected to the clamping drive rod of the feeding and unloading integrated machine through a rotating shaft.

[0011] As a further improvement of this utility model, one end of the outer side of the clamping block is fixedly connected with symmetrically distributed bolts, and the bolts penetrate the support rod. The support rod is in contact with the bolts, and a nut is spirally connected to the outer side of the bolts, and the nut is in close contact with the support rod.

[0022] Example 1

[0023] like Figure 1-4 As shown, a cylindrical medium-to-large forging handling equipment includes a feeding and unloading integrated machine 1. The feeding and unloading integrated machine 1 has a fixed seat 2 on the outside of its clamping drive shaft, and the fixed seat 2 is in contact with the clamping drive shaft of the feeding and unloading integrated machine 1. A hydraulic rod 3 is fixedly connected to the bottom left side of the fixed seat 2, and the hydraulic rod 3 is fixedly connected to the clamping drive shaft of the feeding and unloading integrated machine 1 through a connecting block. A push rod 7 is provided at the bottom right side of the fixed seat 2. The other end of the push rod 7 is rotatably connected to a support rod 8 through a rotating shaft. One end of the support rod 8 contacts a clamping block 10 with one end set in an arc shape.

[0024] like Figure 1-2As shown, in order to solve the problem of poor stability when the fixed seat 2 moves, guide shafts 5 are provided on both the front and rear sides of the top of the fixed seat 2, and the guide shafts 5 pass through the fixed seat 2. The guide shafts 5 are slidably connected to the fixed seat 2. A fixing block 6 is fixedly connected to the end of the guide shaft 5, and the fixing block 6 is fixedly connected to the clamping drive shaft of the feeding and unloading integrated machine 1. By setting two guide shafts 5 to limit and guide the fixed seat 2, the stability of the fixed seat 2 when moving is better.

[0025] like Figure 3 As shown, in order to solve the problem of interference between the clamping drive rod of the integrated feeding and unloading machine 1 and the push rod 7 when the support rod 8 moves, the bottom inner side of the fixed base 2 is slidably connected to both the front and rear ends of the fixed base 2. The limit block 9 is rotatably connected to the push rod 7 through a rotating shaft. By making one end of the push rod 7 rotatably connected to the limit block 9 that slides with the fixed base 2 through the rotating shaft, when the clamping drive rod of the integrated feeding and unloading machine 1 moves the support rod 8, the limit block 9 at one end of the push rod 7 slides with the fixed base 2 through the support rod 8, which can prevent interference with the push rod 7.

[0026] like Figure 3 As shown, in order to solve the problem of large friction between the limiting block 9 and the fixed seat 2 when sliding, a ball bearing 4 is rotatably connected to the outer side of the limiting block 9, and the ball bearing 4 is symmetrically distributed on the outer side of the limiting block 9. The ball bearing 4 contacts the fixed seat 2. By making the limiting block 9 contact the fixed seat 2 through the symmetrically distributed ball bearing 4, large friction between the limiting block 9 and the fixed seat 2 when sliding can be prevented.

[0027] like Figure 1-2 As shown, in order to solve the problem of inconvenience in quickly controlling the erection of forgings, the angular rotation range of the support rod 8 and the clamping block 10 is 0°-90°, and the top of the support rod 8 is rotatably connected to the clamping drive rod of the feeding and unloading integrated machine 1 through a rotating shaft. By making the angular rotation range of the support rod 8 and the clamping block 10 both 0°-90°, when the support rod 8 is pushed to rotate by the push rod 7, and the rotation of the forging held by the clamping block 10 is further controlled, it is convenient to quickly control the erection of the forging.

[0028] like Figure 2 and Figure 4 As shown, in order to solve the problem of inconvenience in periodically replacing the clamping block 10, a symmetrically distributed bolt 11 is fixedly connected to one end of the outer side of the clamping block 10, and the bolt 11 passes through the support rod 8. The support rod 8 is in contact with the bolt 11, and a nut 12 is screwed to the outer side of the bolt 11. The nut 12 is in close contact with the support rod 8. By periodically using a wrench or other tools to rotate the nut 12 to disengage it from the bolt 11, the worn clamping block 10 can be removed from the outer side of the support rod 8, which facilitates the periodic replacement of the clamping block 10.

[0029] like Figure 1-3As shown, to address the issue of difficulty in controlling the extension of the multi-stage hydraulic rod 13 to a specified length so that the clamping block 10 is held at half the position of the forging, a multi-stage hydraulic rod 13 is fixedly connected to the center of the right end of the bottom inner side of the fixed base 2. A connecting shaft 14 is fixedly connected to the right end of the multi-stage hydraulic rod 13, and a limit baffle 15 is fixedly connected to the other end of the connecting shaft 14. The operator inputs the forging length L in the control screen HMI in the cab, and the PLC controller controls the multi-stage hydraulic rod 13 to extend L / 2, pushing the connecting shaft 14 and the limit baffle 15. The baffle 15 moves so that the distance between it and the clamping block 10 is equal to L / 2. Then, the feeding and unloading machine 1 is controlled to drive the baffle 15 to contact one end of the forging. When the operator observes through the cab that the baffle 15 is in contact with one end of the forging, the clamping drive rod is controlled to move, so that the clamping block 10 retracts from both sides of the support rod 8 to clamp the forging. Finally, the hydraulic rod 13 is controlled to reset through the PLC controller, which further resets the baffle 15. This facilitates the control of the multi-stage hydraulic rod 13 to extend to a specified length so that the clamping block 10 is clamped at half the position of the forging.

[0030] In this embodiment, when a long, cylindrical, medium-to-large forging is fed and unloaded from the heating furnace to the forging platform for forging, the device first removes the long cylindrical forging from the heating furnace. At this point, based on the length of the forging, the multi-stage hydraulic rod 13 is extended to a specified length by the control mechanism located in the cab of the integrated feeding and unloading machine 1. Furthermore, the limiting baffle 15 is moved a specified distance via the connecting shaft 14. The limiting baffle 15 is then moved until the distance from the clamping block 10 is half the length of the forging. After completing the above operations, the forging is removed by controlling the integrated feeding and unloading machine 1 to move the limiting baffle 15. When the feeding... When the operator's cab of the integrated loading and unloading machine 1 observes that the limiting baffle 15 contacts one end of the forging, the multi-stage hydraulic rod 13 is first reset, and then the clamping drive rod of the integrated loading and unloading machine 1 is controlled to drive the clamping block 10 on the outside of the support rod 8 to clamp the forging. This allows the clamping position to be at half the position of the forging, thus improving the balance of the forging during the handling process. At this time, during the clamping process of the forging, as the two support rods 8 move closer to each other, the push rod 7 will push the limiting block 9 and the fixed seat 2 to slide. When the forging is clamped and then transferred to the forging platform, the hydraulic rod 3 is extended to further push the fixed seat 2 to move along the guide shaft 5. The fixed seat 2 pushes the push rod 7 through the limit block 9. The push rod 7, in turn, pushes the support rod 8 to rotate. The support rod 8 then rotates the forging through the clamping block 10. After the forging rotates 90 degrees, it can be observed from the operator's cab of the integrated feeding and unloading machine 1 that the forging has been erected. The operator then controls the integrated feeding and unloading machine 1 to place the forging on the forging platform for forging. During the use of the device, the clamping block 10 is prone to wear due to prolonged use when clamping the forging. At this time, by periodically using a wrench or other tools to loosen the screw connection between the nut 12 and the bolt 11, the worn clamping block 10 can be removed from the outside of the support rod 8. The clamping block 10 can be periodically cleaned. The replacement of part number 0 ensures stability when the device clamps the forging, reducing the risk of forging detachment during handling. The automatic control system for forging clamping, handling, and rotation described in this system is fully implementable in industrial automation. It can be implemented based on a combination of PLC + HMI + hydraulic drive + sensor feedback. Several established brands on the market can directly provide hardware products and supporting software platforms. Control can be achieved simply through programming. For example, Siemens S7-1200 / S7-1500 + KTP700 / 900 (HMI) series can be purchased and used with TIAPortal programming software. Alternatively, Mitsubishi FX5U / FX3U + GOT2000 series can be used with the corresponding programming software GT Designer. Programming and control are not the focus of this invention and will not be described in detail here. The aforementioned products can be purchased directly to implement the necessary steps.
