Description

Technical Field

[0001] This utility model relates to the field of forging processing technology, and in particular to an automatic forging clamping device. Background Technology

[0002] Forgings are workpieces or blanks obtained by applying pressure to a metal billet, causing it to undergo plastic deformation. Forgings have a wide range of applications, often used to manufacture critical parts subjected to high loads and harsh operating conditions, such as aircraft engine blades and ship propellers. Forgings typically require fixing during processing, thus necessitating the use of specialized clamping devices.

[0003] Chinese utility model patent CN221434845U discloses a forging processing positioning device. This device comprises a deflection shaft, a U-shaped bearing rod, a magnetic locking bolt, a locking hole, a mounting base, a drive motor, a connecting disc, a rotating seat, connecting bolts, and movable balls. This allows the device to adjust the deflection angle of the positioning seat and the workpiece through the movable connection between the deflection shaft at the bottom of the positioning seat and the U-shaped bearing rod. The drive motor rotates the U-shaped bearing rod and the upper positioning seat on the mounting base, thereby adjusting the orientation of the workpiece, facilitating user operation, and improving the processing efficiency of the device. Regarding the aforementioned related technology, the inventors believe the following defects exist:

[0004] In practical use, this device lacks an integrated structure for cleaning the surface of forgings. As a result, when grinding, drilling, or cutting forgings, debris remains on the surface that is difficult to clean. Therefore, workers need to clean the surface of forgings separately, which is not only troublesome but also reduces the processing efficiency of forgings. To address this, we provide an automatic forging clamping device. Utility Model Content

[0005] To address the problem in the background art where it is difficult to automatically clean the debris left on the surface of forgings during processing, thus affecting the processing efficiency of forgings, this utility model provides an automatic forging clamping device.

[0006] This utility model is achieved by the following technical solution: an automatic clamping device for forgings, including an L-shaped processing table and a chip removal component. A fixed clamping plate is fixedly connected to the L-shaped processing table, and a hydraulic cylinder is also fixedly connected to the L-shaped processing table. A movable clamping plate is fixedly connected to the telescopic end of the hydraulic cylinder.

[0007] The chip removal assembly includes a movable rod slidably connected to an L-shaped machining table. One end of the movable rod is fixedly connected to a pull block, and the other end is fixedly connected to a connector. A brush plate is provided below the connector. A spring is sleeved on the outside of the movable rod. A pin hole is opened on the movable rod, and a pin is inserted into the pin hole. A strip groove is opened on the L-shaped machining table, and the strip groove is slidably connected to the pin. Crossbars are fixedly connected to both sides of the strip groove. The same movable plate is slidably connected to the outside of the two sets of crossbars. A connecting rod is symmetrically hinged between the movable plate and the pin through a hinge. A second spring is sleeved on the outside of the crossbar, and one end of the second spring is fixedly connected to the movable plate.

[0008] As a further improvement to the above solution, the top of the brush plate is rotatably connected to a lead screw, and the lead screw is threadedly connected to the connector. The top of the brush plate is also symmetrically fixedly connected to a guide rod, and the guide rod is slidably connected to the connector.

[0009] As a further improvement to the above solution, a positioning ring is provided on the outside of the movable rod.

[0010] As a further improvement to the above solution, the two ends of the spring are fixedly connected to the pull block and the L-shaped processing table, respectively.

[0011] As a further improvement to the above solution, an anti-detachment plate is fixedly connected to the end of the crossbar, and the anti-detachment plate is fixedly connected to the other end of the second spring.

[0012] As a further improvement to the above solution, a push rod is fixedly connected to the top of the movable clamping plate.

[0013] As a further improvement to the above solution, anti-slip pads are added to the opposite surfaces of both the fixed clamp and the movable clamp.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model, when the forging is released after processing, the movable clamping plate moves away from the forging and drives the push rod to move together. When the push rod contacts the movable plate, it pushes the movable plate to slide on the crossbar. Utilizing the hinged connection between the movable plate, the pin, and the connecting rod, the pin can be driven to move vertically downward, thereby disengaging the pin from the pin hole. At this time, under the rebound action of the spring and the sliding connection between the movable rod and the L-shaped processing table, the brush plate will automatically move towards the surface of the forging, thus facilitating the removal of debris from the surface of the forging. This effectively avoids the problem of affecting the processing efficiency of forgings due to the difficulty in automatically cleaning the debris remaining on the surface of the forging during processing.

[0016] 2. This utility model enables the brush plate to move vertically by rotating the lead screw and sliding between the guide rod and the connecting part, thereby facilitating the adjustment of the height position of the brush plate according to the actual thickness of the forging, and thus improving the applicability of the device.

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0024] Example 1:

[0025] Please combine Figure 1-4 An automatic forging clamping device according to this embodiment includes an L-shaped processing table 1, a fixed clamping plate 2 fixedly connected to the L-shaped processing table 1, a hydraulic cylinder 3 fixedly connected to the L-shaped processing table 1, and a movable clamping plate 4 fixedly connected to the telescopic end of the hydraulic cylinder 3.

[0026] A chip removal assembly for automatically cleaning the surface of forgings includes a movable rod 101 slidably connected to an L-shaped machining table 1. One end of the movable rod 101 is fixedly connected to a pull block 102, and the other end is fixedly connected to a connector 103. A brush plate 104 is positioned below the connector 103. A spring 105 is sleeved on the outside of the movable rod 101, with both ends of the spring 105 fixedly connected to the pull block 102 and the L-shaped machining table 1, respectively. A pin hole 106 is provided on the movable rod 101, and a pin 107 is inserted into the pin hole 106. A strip groove is provided on the L-shaped machining table 1, and the strip groove is slidably connected to the pin 107. Crossbars 108 are fixedly connected to both sides of the strip groove. The two sets of crossbars 108 are slidably connected to the same movable plate 109. The movable plate 109 and... A connecting rod 110 is symmetrically hinged between the pins 107 via a hinge. A second spring 111 is sleeved on the outside of the crossbar 108, and one end of the second spring 111 is fixedly connected to the movable plate 109. An anti-detachment plate is fixedly connected to the end of the crossbar 108, and the anti-detachment plate is fixedly connected to the other end of the second spring 111. A lead screw 5 is rotatably connected to the top of the brush plate 104, and the lead screw 5 is threadedly connected to the connector 103. A guide rod 6 is also symmetrically fixedly connected to the top of the brush plate 104, and the guide rod 6 is slidably connected to the connector 103 to facilitate adjustment of the vertical height of the brush plate 104. A positioning ring 112 is fixedly sleeved on the outside of the movable rod 101 to facilitate quick alignment of the pin hole 106 with the pin 107. A push rod 113 is fixedly connected to the top of the movable clamping plate 4 to facilitate pushing the movable plate 109 to move together.

[0027] The implementation principle of the automatic forging clamping device in this embodiment is as follows: First, the forging is placed between the fixed clamping plate 2 and the movable clamping plate 4. Then, the hydraulic cylinder 3 is activated to push the movable clamping plate 4 closer to the forging until it is clamped between the fixed clamping plate 2 and the movable clamping plate 4. After the forging is ground, drilled, or cut, the hydraulic cylinder 3 is activated to move the movable clamping plate 4 away from the forging. As the movable clamping plate 4 moves away from the forging, it also moves the push rod 113. When the push rod 113 contacts the movable plate 109, it pushes the movable plate 109 to slide on the crossbar 108. Utilizing the hinged connection between the movable plate 109, the pin 107, and the connecting rod 110, the pin 107 can be moved vertically downward, thereby disengaging the pin 107 from the pin hole 106. The spring 111 will then be compressed. Under the rebound action of spring 105 and the sliding cooperation between movable rod 101 and L-shaped processing table 1, brush plate 104 will automatically move towards the surface of forging, thus facilitating the removal of debris from the surface of forging. This effectively avoids the problem of affecting the processing efficiency of forging due to the difficulty in automatically cleaning the debris remaining on the surface of forging during processing. Finally, the forging can be removed from L-shaped processing table 1. When clamping for subsequent forgings, simply pull pull block 102 to drive brush plate 104 to reset until positioning ring 112 contacts L-shaped processing table 1. At this time, when hydraulic cylinder 3 pushes movable clamping plate 4 to clamp forging, pin shaft 107 will automatically reset and re-insert into pin hole 106 under the rebound action of spring 111. This cycle can achieve automatic cleaning of forgings.

[0028] Example 2:

[0029] Based on Example 1, this embodiment is further improved by adding anti-slip pads 7 to the opposing surfaces of the fixed clamping plate 2 and the movable clamping plate 4, which can increase the friction between the fixed clamping plate 2 and the movable clamping plate 4 and the forging, thereby improving the clamping and fixing effect on the forging.

[0030] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
