Description

Technical Field

[0001] This utility model belongs to the technical field of forging auxiliary equipment, specifically relating to a forging clamp. Background Technology

[0002] Currently, the forging process involves clamping the forging billet with pliers, then performing a series of steps such as bulging, punching, and rolling to finally forge it into a disc-shaped or shaft-shaped forging. Since forgings are formed by repeatedly hammering the forging billet with pliers to achieve the desired shape, different sizes and shapes of pliers are needed to clamp the billet when processing shaft or disc-shaped forgings. However, this method requires frequent changes to different pliers, increasing costs and reducing efficiency.

[0003] Furthermore, the clamping surfaces of existing clamps are generally flat and the clamping end face area is small. When clamping shaft forgings with curved surfaces, different diameters, or irregular outer surfaces, the contact area between the clamp and the forging is small due to the influence of the curved and irregular outer surfaces. The forging can easily fall off the clamp, posing a risk of accidentally injuring workers. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a simple forging clamp that is suitable for clamping different types of shaft forgings and reducing costs.

[0005] The technical solution for the purpose of this utility model is:

[0006] A forging clamp includes a left clamp arm and a right clamp arm. Both the left clamp arm and the right clamp arm are provided with a first clamping claw. The clamping opening of the first clamping claw is an arc-shaped clamping opening. The front end of the first clamping claw is provided with a second clamping claw. The clamping surface of the second clamping claw is provided with a groove.

[0007] Furthermore, the first jaw is fixedly connected to the second jaw.

[0008] Furthermore, the first jaw is hinged to the second jaw.

[0009] Furthermore, the second jaw is a rectangular clamping block, the groove is provided in the middle of the clamping surface of the rectangular clamping block, the mounting part is provided on the back of the rectangular clamping block, and the mounting part of the rectangular clamping block is connected to the first jaw.

[0010] Furthermore, the mounting part is provided with a first mounting hole, and the front end of the first clamping claw is provided with a second mounting hole, and the first mounting hole of the mounting part of the rectangular clamping block cooperates with the second mounting hole of the first clamping claw.

[0011] Furthermore, the cross-section of the groove is either circular or triangular.

[0012] Furthermore, the arc-shaped surface is a superior arc surface.

[0013] Furthermore, the clamping surface of the second jaw is also provided with several anti-slip teeth.

[0014] Furthermore, the anti-slip teeth are strip-shaped teeth or wavy teeth.

[0015] The above technical solution has the following beneficial effects:

[0016] This invention has a simple structure. The first jaw can hold a disc-shaped forging. The front end of the first jaw is provided with a second jaw, which can hold shaft-like segments. This reduces the need for different clamping jaws, lowers costs, and eliminates the need to change different clamping jaws, thus improving work efficiency.

[0017] The second jaw is a rectangular clamping block. The clamping surface of the rectangular clamping block has a groove in the middle. The back of the rectangular clamping block has a mounting part with a first mounting hole. The front end of the first jaw has a second mounting hole. The first mounting hole of the mounting part of the rectangular clamping block and the second mounting hole of the first jaw cooperate to facilitate maintenance and replacement of the second jaw.

[0018] The groove has a circular arc cross-section, which increases the contact area of ​​the shaft forgings, makes the clamping more stable, and effectively prevents the forgings from falling off the clamp, thereby avoiding the risk of accidental injury to the staff and making it safer to use.

[0019] The groove has a triangular cross-section and can be applied to shaft forgings with different arc surfaces, different diameters, or irregular outer surfaces. This makes it more versatile and also makes clamping more stable, avoiding the risk of safety accidents.

[0020] The second jaw is also provided with several anti-slip teeth on its gripping surface, which further improves the stability of gripping.

[0021] The following description, in conjunction with the accompanying drawings and specific embodiments, provides further details. Attached Figure Description

[0025] Figure 4 This is a partial schematic diagram of specific embodiment 2.

[0026] In the attached diagram, 1 is the first jaw, 1-1 is the positioning step, 1-2 is the hinge hole, 2 is the second jaw, 2-1 is the groove, 2-2 is the mounting part, and 2-3 is the anti-slip tooth. Detailed Implementation Specific Implementation

[0028] See Figures 1 to 3 As shown, a forging clamp includes a left clamp arm, a right clamp arm, two first clamping jaws, and two second clamping jaws. Each of the left and right clamping arms is equipped with a first clamping jaw 1. One end of each first clamping jaw 1 has a connecting portion for connecting to the clamping arm. The clamping opening of the first clamping jaw 1 is an arc-shaped clamping opening for clamping disc-shaped forgings. A second clamping jaw 2 is provided at the front end of each of the two first clamping jaws 1. The first clamping jaws 1 and the second clamping jaws 2 are fixedly connected by welding or bolts. In this specific embodiment: the first clamping jaw 1 is composed of a vertical section and an arc-shaped section. The arc-shaped section is the clamping opening, the vertical section has the connecting portion, and the front end of the arc-shaped section has the second clamping jaw 2.

[0029] The first jaw and the second jaw may be hinged, either by a pivot hinge or a ball joint hinge. The hinge allows for flexible adjustment of the opening between the two first jaws, expanding the range of applications for irregular or round forgings.

[0030] The second jaw 2 has a groove on its clamping surface. The groove has a circular arc or triangular cross-section and is used to clamp shaft forgings. In this specific embodiment, the groove has a circular arc cross-section, and the arc surface of the circular arc is a superior arc surface.

[0031] The second jaw 2 is a rectangular clamping block, which can be a cube or a cuboid. In this specific embodiment, a cuboid is used. The rectangular clamping block has a groove 2-1 in the center of its clamping surface, and a mounting portion 2-2 on its back. This mounting portion 2-2 can be directly welded to the first jaw 1. Alternatively, the mounting portion 2-2 has a first mounting hole, and the front end of the first jaw 1 has a second mounting hole. The first mounting hole of the mounting portion 2-2 of the rectangular clamping block mates with the second mounting hole of the first jaw 1. In this specific embodiment, bolts are used to fix the rectangular clamping block to the first jaw 1.

[0032] In this specific embodiment: the forging clamp can be used for manual clamping, or the left and right clamp arms can be mounted on the frame. In this specific embodiment: the connecting part of the first clamp claw is provided with a positioning step 1-1 and a hinge hole 1-2. The first clamp claw 1 is locked onto the left and right clamp arms of the operating machine frame through the positioning step 1-1 for fastening the first clamp claw. The connection method between the first clamp claw and the clamp arm can also adopt existing connections, which are not limited. It is hinged to the clamp arm of the operating machine frame through the engagement of the pin and the hinge hole 1-2. The frame drives the left clamp arm, the right clamp arm, the first clamp claw, and the second clamp claw to open and close. The frame is driven by a hydraulic cylinder or a pneumatic cylinder. During operation, the left and right clamp arms move closer or further apart. Compared with manual operation, this frame enables the clamp to hold large shaft-type workpieces. Specific Implementation

[0033] See Figure 4 As shown, the feature of this embodiment is that the clamping surface of the second jaw 2 is also provided with a plurality of anti-slip teeth 2-3. The anti-slip teeth are strip teeth or wavy teeth. In this specific embodiment, the cross-section of the groove is arc-shaped and the anti-slip teeth are strip teeth. Other features are the same as in specific embodiment 1, so this specific embodiment is omitted here.
