Description

Technical Field

[0001] The invention relates to the technical field of anchor bolt processing, and in particular to a local hot forging rapid cooling device and a local hot forging rapid cooling method. Background Art

[0002] When processing the material rod (blank) of the anchor bolt, the material rod is first moved to the heater for local heating, and then the head end of the locally heated material rod is moved to the punching machine for punching, the head end of the material rod is upset, and finally the upset material rod is moved to the cooling pool for cooling.

[0003] Currently, when the material bar is partially cooled, that is, the upsetting head end is cooled, workers are required to wear heat-insulating gloves or hold or clamp the material bar with clamping tools so that the head end of the material bar can be immersed in the cooling pool for cooling.

[0004] However, during the cooling process of the head end of the material rod, the worker's hands need to use tools to keep holding or clamping the material rod to maintain the stability of the material rod. This high labor-intensive cooling operation will affect the cooling efficiency. Summary of the invention

[0005] One of the purposes of the present invention is to solve the problem in the prior art that when cooling a part of a material bar, a worker is required to maintain a stable state of the material bar.

[0006] A second object of the present invention is to provide a method for rapid cooling of local hot forging.

[0007] In order to achieve one of the above-mentioned purposes, the present invention adopts the following technical solution: a local hot forging rapid cooling device, including a cooling box, the local hot forging rapid cooling device also includes a swing beam, a connecting head is arranged at the bottom of the swing beam, a fixed seat is arranged on the box mouth side of the cooling box, and the connecting head is rotatably connected to the fixed seat.

[0008] It should be noted that the contact surface between the connector and the fixing seat has friction resistance, by means of which the swing beam can be stabilized in a horizontally flat state.

[0009] A storage plate is provided on the swing beam, and a limiting unit is provided at the front end of the storage plate. The limiting unit is a structure that acts as a barrier in front of the storage plate.

[0010] When the swing beam is in a horizontally flat state, the storage plate and the limiting unit are suspended above the box opening of the cooling box.

[0011] In the above technical solution, in the embodiment of the present invention, after the head end of the material bar is hot forged and upset, the material bar is placed on the placement plate, and the weight of the material bar presses the placement plate. At this time, the swing beam is controlled to rotate with the rotation connection position of the connecting head and the fixing seat as the fixed point, and at the same time, the limiting unit in front of the placement plate contacts the head end of the material bar to limit the movement of the material bar.

[0012] When the swing beam rotates and the placement plate falls into the cooling box, the head end of the material rod is immersed in the coolant in the cooling box for cooling. After cooling, pull the rear end of the swing beam to rotate the swing beam with the rotation connection position of the connecting head and the fixed seat as the fixed point, so that the swing beam and the placement plate are reset, and then the material rod can be removed.

[0013] The beneficial effects of the present invention are:

[0014] The present invention rotatably mounts the swing beam on the cooling box to form a structure with a "lever" effect. Based on this, a placement plate for placing material rods is arranged on the swing beam, and a limit unit for blocking the tilting displacement of the material rod is arranged in front of the placement plate. When the head end of the material rod needs to be cooled, the material rod can be directly placed on the placement plate. Because the placement plate is suspended above the box opening of the cooling box, the swing beam can quickly rotate the swing beam by relying on the weight of the material rod or the force on its own rear end (which can be manual or the telescopic mechanism described below), so that the head end of the material rod is immersed in the coolant in the cooling box for cooling. During the cooling process, there is no manual intervention, which solves the problem in the prior art that workers are required to maintain the cooling state of the material rod when cooling a part of the material rod (the head end of the material rod).

[0015] Furthermore, in an embodiment of the present invention, the middle of the storage plate is a concave structure.

[0016] Furthermore, in the embodiment of the present invention, the storage plate has a concave conical structure formed by bending in the middle, and the conical structure is wide at the top and narrow at the bottom.

[0017] Furthermore, in an embodiment of the present invention, a gap is left between the limiting unit and the top of the swing beam.

[0018] Furthermore, in an embodiment of the present invention, the limiting unit is a bent strip structure. After the strip structure is bent, the front end of the limiting unit forms an inverted "V" structure, so that a "V"-shaped accommodating opening extending inward is formed under the inverted "V" structure.

[0019] Furthermore, in an embodiment of the present invention, the tail end of the limiting unit is bent to form a connecting end, and the connecting end is fixed to the storage plate.

[0020] Furthermore, in an embodiment of the present invention, an auxiliary plate is also provided on the swing beam, and the auxiliary plate has the same structure as the storage plate.

[0021] A plurality of threaded holes are arranged at intervals on the side of the swing beam, a positioning bar on the side of the swing beam is connected to the threaded holes through a threaded fastener, and the positioning bar is fixedly connected to the auxiliary plate, so that the auxiliary plate is fixed on the swing beam.

[0022] Furthermore, in an embodiment of the present invention, the local hot forging rapid cooling device also includes a telescopic mechanism, and the telescopic end of the telescopic mechanism is movably connected to the tail plate of the swing beam.

[0023] A fixing platform is arranged on the cooling box side, and the lower end of the telescopic mechanism is movably connected to the fixing platform.

[0024] By pushing or pulling the tail plate at the rear end of the swing beam through the telescopic end of the telescopic mechanism, the swing beam can be controlled to rotate with the rotation connection position between the connector and the fixed seat as the fixed point. In this way, the storage plate and its loading rod can fall into the cooling box at a uniform speed, avoiding the storage plate and its loading rod from moving with acceleration, and colliding strongly with the coolant in the cooling box, causing the coolant to splash out of the cooling box.

[0025] In order to achieve the second of the above-mentioned objectives, the present invention adopts the following technical solution: a local hot forging rapid cooling method, the local hot forging rapid cooling method is based on the local hot forging rapid cooling device described in one of the above-mentioned invention objectives, and the local hot forging rapid cooling method comprises the following steps:

[0026] After the head end of the material rod is hot forged and upset, the material rod is placed on a placing plate, and the weight of the material rod presses the placing plate.

[0027] At this time, the swing beam is controlled to rotate with the rotation connection position of the connecting head and the fixing seat as a fixed point, and during the rotation process, the limiting unit in front of the storage plate contacts the head end of the material rod to limit the movement of the material rod.

[0028] When the swing beam rotates and the placement plate falls into the cooling box, the head end of the material rod is immersed in the coolant in the cooling box for cooling treatment.

[0029] After cooling is completed, pull the rear end of the swing beam to cause the swing beam to rotate with the rotation connection position of the connecting head and the fixed seat as the fixed point, so that the swing beam and the storage plate are reset. At this time, the material rod can be removed.

[0030] Furthermore, in an embodiment of the present invention, after the material rod is placed on the storage plate, the tail plate at the rear end of the swing beam is pushed by the telescopic end of the telescopic mechanism to control the swing beam to rotate with the rotational connection position between the connecting head and the fixed seat as a fixed point.

[0031] When cooling is completed, the tail plate at the rear end of the swing beam is pulled by the telescopic end of the telescopic mechanism to control the swing beam to rotate with the rotation connection position of the connecting head and the fixed seat as the fixed point, so that the swing beam and the storage plate are reset. At this time, the material rod can be removed. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] In order to make the purpose and technical solution of the present invention clearly and completely described, and the advantages more clearly understood, the embodiments of the present invention are further described in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, rather than all of the embodiments, and are only used to explain the embodiments of the present invention, and are not used to limit the embodiments of the present invention.

In addition, the terms "one", "first", "second", "third", "fourth", "fifth", "sixth" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0045] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0046] For the purpose of simplicity and illustration, the principles of the embodiments are mainly described by reference to examples. In the following description, many specific details are presented to provide a thorough understanding of the embodiments. However, it is obvious that for ordinary technicians in this field, these embodiments may not be limited to these specific details in practice. In some instances, the known local hot forging rapid cooling method and structure are not described in detail to avoid making these embodiments unnecessarily difficult to understand. In addition, all embodiments can be used in combination with each other.

[0047] Embodiment 1:

[0048] It should be noted that the drawings in the specification are the contents of the specification. The structural shapes, connection relationships, matching relationships, and positional relationships that can be obtained without any doubt in the drawings in the specification should be understood as the contents of the specification.

[0049] A local hot forging rapid cooling device, such as Figure 1 As shown, it includes a cooling box 10, and the local hot forging rapid cooling device also includes a swing beam 20, a connecting head 22 is arranged at the bottom of the swing beam 20, a fixing seat 11 is arranged on the box opening side of the cooling box 10, and the connecting head 22 is rotatably connected to the fixing seat 11.

[0050] It should be noted that the contact surface between the connecting head 22 and the fixing seat 11 has friction resistance, and with the help of this friction resistance, the swing beam 20 can be stably placed in a horizontally flat state.

[0051] like Figure 2As shown, a storage plate 21 is provided on the swing beam 20 , and a limiting unit 30 is provided at the front end of the storage plate 21 . The limiting unit 30 is a structure that acts as a barrier in front of the storage plate 21 .

[0052] like Figure 1 As shown, when the swing beam 20 is in a horizontally flat state, the storage plate 21 and the limiting unit 30 are suspended above the box opening of the cooling box 10.

[0053] Implementation steps: Figure 3 As shown, after the head end of the material rod A is hot forged and upset, the material rod A is placed on the placement plate 21, and the weight of the material rod A presses the placement plate 21. At this time, the swing beam 20 is controlled to rotate with the rotation connection position of the connecting head 22 and the fixing seat 11 as a fixed point, and during the rotation process, the limiting unit 30 in front of the placement plate 21 contacts the head end of the material rod A to limit the movement of the material rod A.

[0054] like Figure 4 As shown, when the swing beam 20 rotates and the placement plate 21 falls into the cooling box 10, the head end of the material rod A is immersed in the coolant in the cooling box 10 for cooling. After the cooling is completed, the rear end of the swing beam 20 is pulled, so that the swing beam 20 rotates with the rotation connection position of the connecting head 22 and the fixing seat 11 as the fixed point, so that the swing beam 20 and the placement plate 21 are reset, and at this time, the material rod A can be removed.

[0055] One of the advantages of the present invention is that the swing beam 20 is rotatably mounted on the cooling box 10 to form a structure with a "lever" effect. Based on this, a placement plate 21 for placing the material bar A is provided on the swing beam 20, and a limit unit 30 for blocking the tilt displacement of the material bar A is provided in front of the placement plate 21. When the head end of the material bar A needs to be cooled, the material bar A can be directly placed on the placement plate 21. Because the placement plate 21 is suspended above the box opening of the cooling box 10, the swing beam 20 can quickly rotate the swing beam 20 by the weight of the material bar A or by the force on its own rear end (which can be manual or the telescopic mechanism 40 described below), so that the head end of the material bar A is immersed in the coolant in the cooling box 10 for cooling. During the cooling process, there is no manual intervention, which solves the problem that when cooling the part of the material bar A (the head end of the material bar A) in the prior art, workers are required to maintain the cooling state of the material bar A.

[0056] Specifically, Figure 2 As shown, the middle of the placing plate 21 is a concave structure. When the material rod A is placed in the concave part of the placing plate 21, the wall surfaces on both sides of the concave can block the lateral movement of the material rod A, thereby preventing the material rod A from falling off the placing plate 21.

[0057] More specifically, if Figure 2As shown, the middle of the placing plate 21 is a concave conical structure formed by bending, and the conical structure is a structure that is wide at the top and narrow at the bottom. When the material rod A is placed in the conical structure of the placing plate 21, the inclined walls on both sides of the conical structure can not only prevent the material rod A from moving sideways, but also restrict the material rod A to the center position of the placing plate 21 and reduce the possibility of the material rod A shaking.

[0058] The second advantage of the present invention is that after the material bar A is placed on the placement plate 21, the material bar A can be centrally positioned through the tapered structure of the placement plate 21, and the material bar A is not easy to move left and right, thereby enhancing the stability of the material bar A. That is, when the placement plate 21 rotates with the swing beam 20, the material bar A is not easy to move left and right, and can be quickly placed in the cooling box 10 for cooling, which is beneficial to improving the cooling efficiency. This improves the problem in the prior art that when cooling a part of the material bar A (the head end of the material bar A), a worker needs to maintain the stability of the material bar A for cooling.

[0059] Specifically, Figure 2 As shown, there is a gap between the limiting unit 30 and the top of the swing beam 20.

[0060] Specifically, Figure 2 As shown, the limiting unit 30 has a receiving opening 31. The receiving opening 31 is used to receive the upset head end of the material rod A, or to avoid the upset head end of the material rod A. More specifically, the limiting unit 30 is a bent strip structure, and the receiving opening 31 is formed by bending the limiting unit 30.

[0061] After the metal strip structure is bent, the front end of the limiting unit 30 forms an inverted "V" structure, and a "V"-shaped receiving opening 31 extending inward is formed under the inverted "V" structure. When the material rod A is placed in the receiving opening 31, it can make double strip contact with the front and rear surfaces of the head end of the material rod A, which not only limits the front and rear displacement of the material rod A, but also the bottom of the receiving opening 31 can contact the left and right positions of the lower end of the head end of the material rod A, limiting the left and right displacement of the head end of the material rod A. The front, rear, left and right positions of the head end of the material rod A are limited by a simple strip structure.

[0062] The third advantage of the present invention is that a worker can simply place the head end of the material bar A into the limiting unit 30, which can limit the movement of the head end of the material bar A in the front, back, left, and right directions, greatly enhancing the stability of the material bar A. In other words, the material bar A can be better adapted to quickly enter the cooling box 10 for cooling, thereby improving the cooling efficiency. This improves the problem in the prior art that when cooling a part of the material bar A (the head end of the material bar A), the worker needs to keep the material bar A stable for cooling.

[0063] More specifically, if Figure 2As shown, the tail end of the limiting unit 30 is bent to form a connecting end 32, and the connecting end 32 is fixed to the storage plate 21. The fixed connection between the connecting end 32 and the storage plate 21 can be achieved by existing welding, fastener connection, clamping and other fixing methods.

[0064] More specifically, if Figure 2 As shown, an auxiliary plate 23 is also provided on the swing beam 20, and the auxiliary plate 23 has the same structure as the storage plate 21. The auxiliary plate 23 is used to bear the weight of the tail end of the large material rod A, so as to avoid the "warping" phenomenon caused by the heavy tail end and light head end of the large material rod A, thereby affecting the cooling operation.

[0065] A plurality of threaded holes 25 are provided at intervals on the side of the swing beam 20 . A positioning bar 24 provided on the side of the swing beam 20 is connected to the threaded holes 25 via a threaded fastener. The positioning bar 24 is fixedly connected to the auxiliary plate 23 , so that the auxiliary plate 23 is fixed on the swing beam 20 .

[0066] When the auxiliary plate 23 is to adapt to the length of material rods A of different specifications, the threaded fasteners of the positioning strip 24 can be removed so that the auxiliary plate 23 is no longer fixed on the swing beam 20. At this time, move the auxiliary plate 23 to a suitable position, that is, when the auxiliary plate 23 can bear the weight of the material rod A, and then use the threaded fasteners to connect the positioning strip 24 to another threaded hole 25.

[0067] Specifically, Figure 5 As shown, the local hot forging rapid cooling device also includes a telescopic mechanism 40 , and a telescopic end 41 on the telescopic mechanism 40 is movably connected to the tail plate 26 of the swing beam 20 .

[0068] A fixing platform 12 is provided on the side of the cooling box 10 , and the lower end of the telescopic mechanism 40 is movably connected to the fixing platform 12 .

[0069] The telescopic mechanism 40 may be an existing air cylinder, hydraulic cylinder or electric cylinder, and the present invention is not limited thereto.

[0070] like Figure 5 , Figure 6 As shown, the tail plate 26 at the rear end of the swing beam 20 can be pushed or pulled by the telescopic end 41 of the telescopic mechanism 40, so that the swing beam 20 can be controlled to rotate with the rotation connection position between the connector 22 and the fixing seat 11 as a fixed point. In this way, the storage plate 21 and its loading rod A can fall into the cooling box 10 at a uniform speed, avoiding the storage plate 21 and its loading rod A from moving with acceleration, and strongly colliding with the coolant in the cooling box 10, causing the coolant to splash out of the cooling box 10.

[0071] Embodiment 2:

[0072] A local hot forging rapid cooling method, the local hot forging rapid cooling method is based on the local hot forging rapid cooling device in the above embodiment 1, and the local hot forging rapid cooling method comprises the following steps:

[0073] After the head end of the material rod A is hot-forged and upset, the material rod A is placed on the placing plate 21 , and the weight of the material rod A presses the placing plate 21 .

[0074] At this time, the swing beam 20 is controlled to rotate with the rotation connection position between the connecting head 22 and the fixing seat 11 as a fixed point. During the rotation, the limiting unit 30 in front of the storage plate 21 contacts the head end of the material rod A to limit the movement of the material rod A.

[0075] When the swing beam 20 rotates and the placing plate 21 falls into the cooling box 10, the head end of the material rod A is immersed in the coolant in the cooling box 10 for cooling treatment.

[0076] After cooling is completed, the rear end of the swing beam 20 is pulled to rotate the swing beam 20 with the rotation connection position between the connecting head 22 and the fixing seat 11 as a fixed point, so that the swing beam 20 and the storage plate 21 are reset. At this time, the material rod A can be removed.

[0077] The present invention rotatably mounts the swing beam 20 on the cooling box 10 to form a structure with a "lever" effect. Based on this, a placement plate 21 for placing the material bar A is provided on the swing beam 20, and a limit unit 30 for blocking the tilt displacement of the material bar A is provided in front of the placement plate 21. When the head end of the material bar A needs to be cooled, the material bar A can be directly placed on the placement plate 21. Since the placement plate 21 is suspended above the box opening of the cooling box 10, the swing beam 20 can quickly rotate the swing beam 20 by means of the weight of the material bar A or the force on its own rear end (which can be manual or the telescopic mechanism 40 described below), so that the head end of the material bar A is immersed in the coolant in the cooling box 10 for cooling. During the cooling process, there is no manual intervention, which solves the problem that when cooling the part of the material bar A (the head end of the material bar A) in the prior art, workers are required to maintain the cooling state of the material bar A.

[0078] Specifically, when the material rod A is placed on the storage plate 21, the telescopic end 41 of the telescopic mechanism 40 pushes the tail plate 26 at the rear end of the swing beam 20, and controls the swing beam 20 to rotate with the rotation connection position between the connecting head 22 and the fixing seat 11 as the fixed point.

[0079] When cooling is completed, the tail plate 26 at the rear end of the swing beam 20 is pulled by the telescopic end 41 of the telescopic mechanism 40, and the swing beam 20 is controlled to rotate with the rotation connection position between the connecting head 22 and the fixed seat 11 as the fixed point, so that the swing beam 20 and the storage plate 21 are reset. At this time, the material rod A can be removed.

[0080] By pushing or pulling the tail plate 26 at the rear end of the swing beam 20 through the telescopic end 41 of the telescopic mechanism 40, the swing beam 20 can be controlled to rotate with the rotation connection position between the connector 22 and the fixing seat 11 as a fixed point. In this way, the storage plate 21 and its loading rod A can fall into the cooling box 10 at a uniform speed, avoiding the storage plate 21 and its loading rod A from moving with acceleration, and colliding strongly with the coolant in the cooling box 10, causing the coolant to splash out of the cooling box 10.

[0081] Although the above describes the illustrative specific embodiments of the present invention so that those skilled in the art can understand the present invention, the present invention is not limited to the scope of the specific embodiments. For those of ordinary skill in the art, as long as various changes are within the spirit and scope of the present invention as defined and determined by the attached claims, all inventions and creations using the concepts of the present invention are protected.
