[0002] Forging is a process of applying pressure to a metal blank using a forging machine to cause it to plastically deform. A trimming device is required during forging processing to remove raised or recessed edges to ensure quality.

[0003] After searching, the existing patent (publication number: CN211565089U) discloses a forging trimming device, comprising a support frame, a processing table is installed on the top of the support frame, a transparent cover and a fixed seat are installed on the top of the processing table, a drive motor is connected to the side bolts of the transparent cover, one end of the fixed frame is connected to the grinding roller, the output end of the drive motor is connected to the grinding roller, a support is installed on the side of the support frame, a water tank is installed on the top of the support, a water pump is installed in the water tank, the output end of the water pump is connected to the water outlet pipe, and the bottom end of the horizontal water pipe is connected to a nozzle. In this utility model, the water pump quickly pumps the water in the water tank into the horizontal water pipe, and the bottom end of the horizontal water pipe is evenly connected to the nozzle. The water sprayed by the nozzle can not only flush away the debris, so that the debris flows into the sewage tank along the sewage pipe, thereby ensuring the cleanliness of the forging, but also reduce the temperature generated during grinding and deburring, thereby avoiding burns when the forging is taken out. In the process of realizing the utility model, the inventor discovered that the prior art has the following problems:

[0004] The existing trimming device needs to be used to cut off the protrusions and depressions on the edge after forging, so the forged workpiece needs to be transferred to the cutting device. However, transferring the forging equipment from the forging equipment to the trimming device requires additional handling operations, and the forgings are often large in size and heavy in weight. Accidents during the handling process will affect the safety of workers. The temperature of the forgings that have just been forged is high, and there is a risk of burns to workers during the transfer process before trimming. In addition, in the scenario of mass production, adjustments are often required during trimming, so that the edge of the entire workpiece is trimmed, which requires secondary adjustments, causing inconvenience and errors in accuracy.

[0005] Therefore, a forging trimming device is proposed to address the above problems. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example 1

[0024] As attached Figures 1 to 4 A forging trimming device shown includes a workbench 1, a forging punch 5, a rotary clamping assembly 7 and a cutting wheel 13. A movable assembly 2 is provided at the front and rear ends of the upper end of the workbench 1. A processing table 8 is provided at the center of the workbench 1. A first gantry 3 is provided at the upper end of the right side of the two groups of movable assemblies 2. A hydraulic cylinder 4 is provided on the upper end surface of the first gantry 3. The forging punch 5 is provided at the output end of the hydraulic cylinder 4. A first slide 6 is provided on the right side of the two groups of movable assemblies 2. The rotary clamping assembly 7 is provided at the upper end of the first slide 6. A second gantry 9 is provided at the upper end of the left side of the two groups of movable assemblies 2. The cutting wheel 13 is provided at the center of the second gantry 9.

[0025] The rotating clamping assembly 7 includes a fixed plate 701, which is arranged at the upper end of the first slider 6. A first electric push rod 702 is arranged on one side of the fixed plate 701, a slide 703 is arranged on one side of the first slider 6, a second slider 704 is arranged on the upper end surface of the slide 703, a second motor 705 is arranged at the upper end of the second slider 704, and a clamping plate 706 is arranged at the output end of the second motor 705.

[0026] Among them: the hydraulic cylinder 4 drives the forging punch 5 to cooperate with the components to forge the metal workpiece through the output end on the first gantry 3. When the forging is completed and the edge of the metal workpiece needs to be cut, the metal workpiece is clamped by two sets of rotating clamping assemblies 7. The control system controls the first electric push rods 702 of the two sets of rotating clamping assemblies 7 to extend and retract, thereby driving the second motor 705 at the connection to extend and retract. At the same time, since the second motor 705 is installed on the second slider 704, it drives the second slider 704 to slide along the outer surface of the slide 703, so that the clamping plates 706 at the output ends of the two sets of second motors 705 are close to each other and close to the metal workpiece. The workpiece is clamped, and this process can firmly fix the workpiece to ensure that it will not be displaced during the subsequent cutting process. It is then moved to the second gantry 9 through two sets of moving components 2. When it is brought to the cutting wheel 13 area, trimming operations can be performed. The clamping plate 706 is driven to rotate by the output end of the second motor 705, thereby driving the metal workpiece to rotate. Subsequently, by adjusting the extension and retraction of the output ends of the two sets of first electric push rods 702, the metal workpiece is controlled to move left and right, making it convenient for the cutting wheel 13 to trim the edges on both sides of the metal workpiece. The integrated design allows forging and cutting to be completed on the same platform, saving production time and avoiding workers' operation and transportation of workpieces.

[0027] Example 2

[0028] Based on Example 1, the solution in Example 1 is further detailed in combination with the following specific working methods. Figures 1 to 4As shown, see the following description for details:

[0029] As a preferred embodiment, the moving component 2 includes a limiting plate 201, which is arranged on both sides of the workbench 1, and a first motor 204 is provided on one side of one group of limiting plates 201. A transmission screw 202 is installed on the opposite surface between the two groups of limiting plates 201, and the output end of the first motor 204 is connected to one end of the transmission screw 202; further, the transmission screw 202 is limited by two groups of limiting plates 201, and the first motor 204 drives the transmission screw 202 to rotate, which is convenient for the slide groove 203.

[0030] As a preferred embodiment, a slide groove 203 is provided under the transmission screw 202, the slide groove 203 and the first slider 6 abut against each other, and the outer surface of the transmission screw 202 engages with the inner cavity of the first slider 6; further, the transmission screw 202 engages with the first slider 6 and can rotate when rotating, but since the first slider 6 abuts against the surface of the slide groove 203, the rotational force is converted into linear motion, and moves smoothly on the surface of the slide groove 203.

[0031] As a preferred embodiment, the outer surface of the slide 703 is engaged with the inner surface of the second slider 704, and the output end of the first electric push rod 702 is connected to the second motor 705 by passing through the fixed plate 701; further, the slide 703 can move on the surface of the second slider 704, and the first electric push rod 702 drives the second motor 705 to perform telescopic adjustment.

[0032] As a preferred embodiment, second electric push rods 10 are provided on both sides of the upper end of the second gantry 9. The output end of the second electric push rod 10 is connected to the lifting plate 11 by passing through the second gantry 9. The lower end of the lifting plate 11 is provided with a third motor 12, and the output end of the third motor 12 is connected to the cutting wheel 13; further, the two groups of second electric push rods 10 control the lifting and lowering of the lifting plate 11 by adjusting their own telescopic lengths, and the third motor 12 starts the cutting wheel 13 to rotate. The lifting plate 11 drives the third motor 12 while lifting and lowering, thereby adjusting the cutting height of the cutting wheel 13, which is convenient for fitting the metal workpiece.

[0033] As a preferred embodiment, the two sets of rotating clamping components 7 correspond to each other in a mirror-image manner, and the clamping plate 706 is circular in shape; further, the two sets of rotating clamping components 7 correspond to each other in a mirror-image manner, so that the metal workpiece can be clamped stably without deviation, and the circular clamping plate 706 clamps the metal workpiece in a close fit.

[0034] The working process of the present invention is as follows: first, the workbench 1 provides the support function of the device, and the hydraulic cylinder 4 of the first gantry 3 drives the forging punch 5 through the output end to forge the metal workpiece on the processing table 8. During the forging process, the metal workpiece is impacted by high pressure to achieve the required shape and size. After the forging is completed, in order to cut the edge of the metal workpiece, the control system starts the two sets of rotary clamping assemblies 7, and then the first electric push rods 702 of the two sets of rotary clamping assemblies 7 are extended and retracted, and the output end passes through the fixed plate 701, thereby driving the second motor 705 at the output end connection to extend and retract. At the same time, since the second motor 705 is installed on the second slider 704, the generated telescopic force drives the second slider 704 to slide along the outer surface of the slide 703, so that the clamping plates 706 at the output ends of the two sets of second motors 705 are close to each other and clamped tightly against the metal workpiece. This process can firmly fix the workpiece;

[0035] Then, the two groups of moving components 2 move to the second gantry 9, and the first motor 204 passes through one of the groups of limit plates 201 to drive the transmission screw 202 to rotate and engage with the first slider 6. When rotating at the same time, the first slider 6 abuts against the surface of the slide groove 203, thereby converting the rotational force into linear motion and moving smoothly on the surface of the slide groove 203. The two groups of first sliders 6 respectively perform linear motion on the outer surfaces of the transmission screws 202 of the two groups of moving components 2, thereby bringing the rotating clamping component 7 and the metal workpiece to the cutting wheel 13 area, and then the two groups of second electric push rods 10 control the lifting plate 11 to rise and fall by adjusting their own telescopic lengths, and the third motor 12 starts the cutting wheel 13 to rotate. The lifting plate 11 also drives the third motor 12 to rise and fall, thereby adjusting the cutting height of the cutting wheel 13, which is convenient for fitting the metal workpiece, thereby trimming the edge of the metal workpiece. The above is the working principle of this forging trimming device.
