Description

Technical Field

[0001] The utility model relates to the technical field of forging clamping, in particular to a forging clamping device used for forging processing. Background Art

[0002] During the processing of forgings, it is generally necessary to heat the blank to a certain temperature in advance to improve its plasticity and facilitate subsequent forging operations. During the processing of most forgings, the staff uses a clamp-type clamping device to clamp the high-temperature blank out of the furnace and transfer it to the next step. The handheld forging clamping device currently used generally suspends a steel chain on the clamping device to make the entire device form a lever-like shape. However, while clamping the forging, the entire device will tilt to one side. At this time, the staff needs to exert greater force to maintain balance. Its overall safety is slightly low and it will consume a lot of manpower. Utility Model Content

[0003] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a forging clamping device for forging processing, so as to solve the problem that most of the handheld forging clamping devices mentioned in the above background technology consume a lot of physical strength of the workers during use.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a forging clamping device for forging processing, comprising a central axis base, a driving assembly is slidably mounted on the top of the central axis base, a balancing assembly is mounted on the central axis base, and two mirror-arranged clamp assemblies are mounted on one end of the driving assembly;

[0005] The central axis base includes a bearing support plate, a positioning sleeve is fixedly mounted on the middle part of the top surface of the bearing support plate by screws, and the positioning sleeve is sleeved on the outer surface of the driving assembly;

[0006] The balancing assembly includes a reinforcing steel plate fixedly mounted on the top of the bearing tray, a multi-section electric push rod is mounted on the reinforcing steel plate, a connecting piece is mounted on the free end of the multi-section electric push rod, and one side of the connecting piece is fixedly connected to the outer side of one end of the driving assembly close to the clamp assembly through a screw.

[0007] Preferably, the clamp assembly includes an outer clamp rod rotatably mounted at one end of the driving assembly, and three notches are formed on the inner wall of the recess of the outer clamp rod, and steel plate structures are fixedly engaged with the insides of the three notches by screws.

[0008] Preferably, three evenly arranged arc-shaped clamping blocks are provided on one side of the recessed portion of the outer clamping rod, and two spring structures arranged side by side are fixedly connected between the three arc-shaped clamping blocks and the steel plate structure.

[0009] Preferably, the drive assembly includes a rigid shell slidably inserted in a positioning sleeve, one end of the rigid shell is fixedly mounted with a transmission structure rotatably connected to the clamp assembly via a flange, and an electric pull rod with a free end connected to the interior of the transmission structure is installed inside the rigid shell.

[0010] Preferably, the drive assembly further comprises a guide steel bar fixedly mounted on the top of the rigid housing, and the top wall of the positioning sleeve is provided with a groove adapted to fit the guide steel bar.

[0011] Preferably, toggle rods are fixedly mounted on both sides of the top of the bearing tray, and a pulley seat is fixedly mounted on the bottom of the bearing tray.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. In the utility model, a lever-like shape is formed between the central axis base and the driving assembly. After the driving assembly cooperates with the two clamping assemblies to clamp the forging, the multi-section electric push rod is driven to retract inward by a set length, so as to drive the driving assembly to slide along the inside of the positioning sleeve away from the clamp assembly through the connecting piece, thereby adjusting the weight of the driving assemblies on both sides of the central axis base to maintain balance, so that the subsequent staff can push the forging clamping device to slide and transfer the forging to the next processing equipment, which is more labor-saving and safer.

[0014] 2. In the utility model, several arc-shaped clamping blocks with spring structures are added to the clamp assembly, and the elastic properties of the spring structure are utilized to give the arc-shaped clamping blocks a small range of adjustability in position and placement angle, thereby making it adaptable to columnar forgings of various sizes.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] To solve the problem that most of the existing handheld forging clamping devices consume a lot of physical strength of the workers during use, please refer to Figure 1-Figure 4 , an embodiment provided by the utility model:

[0022] A forging clamping device for forging processing, comprising a central axis base 1, a driving assembly 2 is slidably mounted on the top of the central axis base 1, a balancing assembly 3 is mounted on the central axis base 1, and two mirror-arranged clamp assemblies 4 are mounted on one end of the driving assembly 2. The driving assembly 2 is basically consistent with the structure in the prior art, and the two clamp assemblies 4 are controlled to open and merge through the operation of the driving assembly 2. In addition, when the forging is clamped in the two clamp assemblies 4 with the balancing assembly 3, the proportion occupied by the driving assemblies 2 on both sides of the central axis base 1 is adjusted;

[0023] Specifically, the central axis base 1 includes a bearing support plate 101, a positioning sleeve 102 is fixedly installed in the middle of the top surface of the bearing support plate 101 by screws, and the positioning sleeve 102 is sleeved on the outer surface of the driving component 2, and the balancing component 3 includes a reinforcing steel plate 301 fixedly installed on the top of the bearing support plate 101, and a multi-section electric push rod 302 is installed on the reinforcing steel plate 301. The relative position between the driving component 2 and the central axis base 1 is adjusted by the telescopic effect of the multi-section electric push rod 302. A connector 303 is installed at the free end of the multi-section electric push rod 302, and one side of the connector 303 is fixedly connected to the outer side of one end of the driving component 2 close to the clamp component 4 by screws;

[0024] Furthermore, the driving component 2 has one end with the clamp component 4 as the tail and the other end as the head, and the overall state is head-heavy and tail-light. Therefore, the connection between the central axis base 1 that supports the driving component 2 and the driving component 2 is relatively far away from the clamp component 4, and the multi-section electric push rod 302 is in an outwardly extended state, so as to maintain the balance of the entire device. When clamping the forging in the subsequent process, the driving component 2 is used to control the two clamp components 4 to open on both sides of the forging and then merge to firmly clamp the forging. At this time, the weight of the tail end of the driving component 2 increases. On this basis, The multi-section electric push rod 302 is contracted inward to a set length (the contraction length is set according to the weight of the clamped forging) to generate a pulling force toward one side on the drive component 2 through the connecting piece 303, so that the drive component 2 slides along the inside of the positioning sleeve 102 toward the side away from the clamp component 4, thereby adjusting the drive component 2 to a state of balanced weight at both ends again, avoiding the entire device from tilting toward one side of the forging, making it more labor-saving and safer for subsequent staff to push the forging clamping device to slide and transfer the forging to the next processing equipment.

[0025] like Figure 1 and Figure 4 As shown, the clamp assembly 4 includes an outer clamp rod 401 rotatably mounted at one end of the driving assembly 2, and three notches are provided on the inner wall of the recess of the outer clamp rod 401, and the steel plate structure 402 is fixedly engaged inside the three notches by screws, and three evenly arranged arc-shaped clamp blocks 403 are provided on one side of the recess of the outer clamp rod 401, and two spring structures 404 arranged side by side are fixedly connected between the three arc-shaped clamp blocks 403 and the steel plate structure 402, and the elasticity and reset function of the spring structure 404 are used to give the arc-shaped clamp blocks 403 a small range of adjustability in position and placement angle, thereby increasing the fit of multiple arc-shaped clamp blocks 403 to the surface of the clamped forging, and at the same time, the spring structure 404 can be adjusted in a small range according to the shape and size of the clamped forging, so as to improve the adaptability of the clamp assembly 4, and in addition, when the surface of the arc-shaped clamp block 403 is damaged and affects the clamping effect, the combined part of the arc-shaped clamp block 403, the spring structure 404 and the steel plate structure 402 can be disassembled and replaced between the outer clamp rod 401.

[0026] Reference Figure 3 As shown, the drive assembly 2 includes a rigid shell 201 that is slidably inserted into the positioning sleeve 102, and one end of the rigid shell 201 is fixedly installed with a transmission structure 202 that is rotatably connected to the clamp assembly 4 through a flange, and the interior of the rigid shell 201 is installed with an electric pull rod 203 whose free end is connected to the interior of the transmission structure 202. The extension and retraction operation of the electric pull rod 203 is coordinated with the transmission performance of the transmission structure 202 to control the opening and merging of the two clamp assemblies 4, wherein the connection method and specific structure between the clamp assembly 4 and the transmission structure 202 are consistent with the prior art, so they are not described in detail here.

[0027] Reference Figure 2 As shown, the drive component 2 also includes a guide steel bar 204 fixedly mounted on the top of the rigid shell 201, and a groove 103 adapted to the guide steel bar 204 is opened on the top wall of the positioning sleeve 102. The guide steel bar 204 and the groove 103 fit each other, which can effectively prevent the drive component 2 from rotating inside the positioning sleeve 102 when the device is clamping the forging, thereby affecting the stability of the entire device. Toggle rods 104 are fixedly mounted on both sides of the top of the support plate 101, and a pulley seat 105 is fixedly mounted on the bottom of the support plate 101. The toggle rod 104 cooperates with the pulley seat 105 to facilitate the device to adjust the direction and move the position.

[0028] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
