Abstract
Description
Technical Field
[0001] This utility model relates to the field of edge pressing device technology, specifically an edge pressing mechanism for irregular forgings. Background Technology
[0002] Forgings are workpieces or blanks obtained by forging and deforming metal billets. Forging can use pressure to make metal billets plastically deformed and change their mechanical properties. Forging can eliminate the porosity and voids in metal and improve the mechanical properties of forgings. However, irregular forgings are prone to problems such as uneven material flow, wrinkling or insufficient filling during the forging process.
[0003] Traditional blank holder mechanisms using fixed blank holder rings are difficult to match for forgings of different shapes, requiring frequent mold changes, resulting in low efficiency. Furthermore, a single blank holder force can cause localized material accumulation or tearing, affecting forming accuracy. In addition, traditional manual lubrication is time-consuming and labor-intensive, which also affects the working efficiency of the device. Therefore, we propose a blank holder mechanism for irregularly shaped forgings. Utility Model Content
[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a blank holder mechanism for irregular forgings. The multi-degree-of-freedom adjustment unit realizes precise lateral and vertical adjustment of the blank holder ring to adapt to complex forging contours. The integrated intelligent lubrication system uniformly lubricates key friction surfaces through rotating spray pipes, extends mold life, significantly reduces scrap rate, improves material utilization, and thus meets the different needs of irregular forgings, effectively solving the problems in the background technology.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a pressing mechanism for irregularly shaped forgings, comprising a frame and a placement groove;
[0006] The frame has a processing table fixed inside. A main hydraulic rod is fixed in a groove on the top surface of the frame. The bottom end of the main hydraulic rod is connected to the middle of the top surface of the pressure seat. Slide rails are fixed on both the left and right sides inside the frame. The slide rails are slidably connected to the slide grooves on the surface of the pressure seat. Placement slots are opened on both the left and right sides of the frame. An adjustment unit is provided inside the placement slot. A pressure ring is installed inside the adjustment unit. Lubrication units are fixed on both the left and right sides of the frame.
[0007] It also includes a controller, which is located on the front side of the frame. The input end of the main hydraulic rod is electrically connected to the output end of the controller, and the input end of the controller is electrically connected to the output end of an external power source.
[0008] The main hydraulic rod is activated to drive the pressure seat to press down and complete the forging and pressing of irregular forgings. The slide rail can increase the stability of the pressure seat lifting and lowering, and the pressure ring can control the flow during the forging process to prevent wrinkling, folding or insufficient filling of burrs and flash.
[0009] Furthermore, the adjustment unit includes a frame, a main linear motor, a bracket, a lead screw, a rotating wheel, a spring, and a mounting bracket. There are two main linear motors, each fixed to the front and rear sides of the placement slot. The inner side of the main linear motor's moving part is connected to one end of the frame. A spring is fixed inside the frame, and the top of the spring is connected to the bottom surface of the bracket. The bracket is slidably installed inside the frame. A rotating wheel is installed on the outer side of the bracket, and the inner end of the rotating wheel is connected to the outer end of the lead screw. The mounting bracket is slidably installed inside the bracket. A screw hole on the surface of the mounting bracket is threaded into the lead screw. The mounting bracket is inserted into the mounting groove on the surface of the pressure ring. The input end of the main linear motor is electrically connected to the output end of the controller. Rotating the rotating wheel causes the mounting bracket to insert into the mounting groove on the surface of the pressure ring to adjust the position of the pressure ring. The main linear motor adjusts the height of the pressure ring to suit different irregular forging molds.
[0010] Furthermore, the adjustment unit also includes a secondary linear motor, a secondary hydraulic rod, a sliding seat, and a pressure plate. There are two sliding seats, each slidably connected to a sliding groove inside a groove on the top surface of the frame. A secondary hydraulic rod is fixed to the top surface of the sliding seat, and the bottom end of the secondary hydraulic rod is connected to the middle of the top surface of the pressure plate. There are two secondary linear motors, which are fixed to the rear side of the groove on the top surface of the frame, respectively. The front side of the moving part of the secondary linear motor is connected to the rear side of the sliding seat. The input ends of the secondary linear motor and the secondary hydraulic rod are electrically connected to the output end of the controller. The secondary linear motor is started to adjust the position of the pressure plate, and the secondary hydraulic rod is started to drive the pressure plate to press down, so as to apply pressure to the edge of the forging in sections, prevent the material from wrinkling or tearing, and improve the uniformity of the forming edge pressing.
[0011] Furthermore, the adjustment unit also includes a fixing plate, a locking rod, and a bidirectional screw. The bidirectional screw is rotatably installed inside the mounting bracket, and the threads at both ends of the bidirectional screw are opposite. The fixing plate has two screw holes on its surface that are threaded to both ends of the bidirectional screw. The locking rod is fixed to the outer side of the fixing plate.

The outlet pipe of the liquid pump is connected to the inlet of the spray pipe. The input ends of the electric push rod, the liquid pump, and the motor are electrically connected to the output end of the controller. When the motor is started, it drives the spray pipe to rotate, and at the same time, the liquid pump sprays lubricant onto the surface of the mold and the pressure ring to reduce friction and mold wear, thereby improving the quality of subsequent pressure ring processing.
[0013] Furthermore, the lubrication unit also includes a liquid level sensor, which is installed on the top surface of the liquid tank. The input end of the liquid level sensor is electrically connected to the output end of the controller. The liquid level sensor detects the remaining liquid in the tank and reminds personnel to add liquid when the liquid level is low, so as to avoid equipment jamming due to lack of oil.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: The blank holder mechanism of this irregular forging has the following advantages:

[0024] Please see Figure 1-4 This embodiment provides a technical solution: a pressing mechanism for irregular forgings, including a frame 1 and a placement groove 8;
[0025] Frame 1: A processing table 4 is fixed inside. A main hydraulic rod 5 is fixed in a groove on the top surface of the frame 1.

The mounting bracket 27 is inserted into the mounting groove on the surface of the pressure ring 9. The input of the main linear motor 22 is electrically connected to the output of the controller 10. Rotating the rotating wheel 25 causes the mounting bracket 27 to be inserted into the mounting groove on the surface of the pressure ring 9 to adjust the position of the pressure ring. The main linear motor 22 adjusts the height of the pressure ring 9 to suit different irregular forging molds. The adjustment unit 2 also includes a secondary linear motor 28 and a secondary linear motor 29. Hydraulic rods 29, sliding seats 210, and pressure plates 211 are provided.

The fixed plate 212 has two screw holes on its surface that are threaded to the two ends of the bidirectional screw 214. The locking rod 213 is fixed to the outer side of the fixed plate 212.

The lubrication unit 3 also includes a liquid level sensor 37, which is installed on the top surface of the liquid tank 32. The input end of the liquid level sensor 37 is electrically connected to the output end of the controller 10. The liquid level sensor 37 detects the remaining liquid in the liquid tank 32 and reminds personnel to add oil when the liquid level is low to avoid equipment jamming due to lack of oil.
[0026] The system also includes a controller 10, which is located on the front side of the frame 1. The input end of the main hydraulic rod 5 is electrically connected to the output end of the controller 10, and the input end of the controller 10 is electrically connected to the output end of an external power source.

The slide rail 7 can increase the stability of the lifting and lowering of the pressure seat 6, and the pressing ring 9 can control the flow during the forging process to prevent wrinkling, folding, or insufficient filling that causes burrs and flash.
[0027] The working principle of the blanking mechanism for irregular forgings provided by this utility model is as follows: The mold is installed onto the surfaces of the processing table 4 and the pressure base 6 respectively. Rotating the rotating wheel 25 causes the mounting bracket 27 to insert into the mounting groove on the surface of the blanking ring 9 to adjust its position. Rotating the bidirectional screw 214 causes the locking rod 213 to insert into the locking hole inside the mounting groove, thus enabling quick replacement of the blanking ring 9. The main linear motor 22 adjusts the height of the blanking ring 9 to suit different irregular forging molds. Activating the main hydraulic rod 5 drives the pressure base 6 downwards to complete the forging and blanking process of the irregular forging. The provided slide rail 7 increases the stability of the lifting and lowering of the pressure base 6, and the provided blanking ring 9... To control the flow during the forging process and prevent wrinkling, folding, or burrs and flash caused by insufficient filling, the auxiliary linear motor 28 is activated to adjust the position of the pressure plate 211, and the auxiliary hydraulic rod 29 is activated to drive the pressure plate 211 downward to apply pressure to the edge of the forging in sections, preventing material wrinkling or tearing and improving the uniformity of the forming edge. After forming the edge, the motor 36 is activated to drive the spray pipe 34 to rotate, and at the same time the liquid pump 32 sprays lubricant onto the surface of the mold and the edge ring 9 to reduce friction and mold wear, thereby improving the quality of subsequent edge pressing. The liquid level sensor 37 is set to detect the liquid level in the liquid tank 32 and remind personnel to replenish when the liquid level is low to avoid equipment jamming due to lack of oil.
[0028] It is worth noting that the controller 10 disclosed in the above embodiments uses model S7-1200, while the main hydraulic rod 5 can be freely configured according to the actual application scenario.
