Description

Technical Field

[0001] This utility model belongs to the field of design or construction technology of positioning in forging, and specifically relates to a movable positioning structure for forging blanks. Background Technology

[0002] The pressure forging process for manufacturing forged blanks is generally a roughing process, representing the initial step in the machining of the parts. On pressure equipment, the molds and positioning methods for forging blanks are relatively simple. Currently, the heated workpiece is manually placed onto the lower mold using pliers, and positioning is completed by visually determining that the workpiece is centered on the lower mold. Then, the pressure drive source of the pressure equipment lowers the upper mold to apply pressure to the workpiece on the lower mold, forming the initial forged blank. The current positioning method produces initial forged blanks with poor consistency, causing inconvenience for subsequent processes such as trimming, or resulting in incomplete initial forging. Furthermore, simply setting a fixed positioning part on the lower mold can interfere with the pressure applied by the upper mold, requiring further improvement and optimization. Summary of the Invention

[0003] In view of the above-mentioned shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a movable positioning structure for forging blanks, so as to avoid the problem of inaccurate positioning in the initial forging process and poor consistency of the pressed initial forging blanks, thereby achieving the effect of improving quality and efficiency.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A forging blank positioning structure includes a pressure device, which includes a lower die base. A lower punch is fixedly connected to the lower die base, and the upper surface of the lower punch is higher than the upper surface of the lower die base. The upper surface of the lower punch is flat to facilitate the placement of the forging. A mounting plate is also fixedly connected to the lower die base, and a linear guide rail and a telescopic drive source are fixedly connected to the mounting plate. A slider is slidably fitted on the linear guide rail, and the telescopic drive source drives the slider to reciprocate along the linear guide rail to move closer to or away from the lower punch. A positioning plate is provided on the slider, one end of which is fixedly connected to the slider, and the free end of the positioning plate extends toward the lower punch to form a positioning part.

[0006] When the slider approaches the lower punch, the free end of the positioning plate is located directly above the lower punch to position the forging.

[0007] When the slider moves away from the lower punch, the free end of the positioning plate moves away from directly above the lower punch and away from the lower punch.

[0008] To further improve the above technical solution, the positioning plate is parallel to the upper surface of the lower mold base, and the free end of the positioning plate is recessed with a V-shaped groove, which forms the positioning part.

[0009] Furthermore, the upper surface of the lower punch is circular, and the forging is cylindrical;

[0010] When the slider is close to the lower punch and the V-shaped groove of the positioning plate is located directly above the lower punch for positioning, the outer circumferential side of the forging abuts against the two inner sidewalls of the V-shaped groove, and the center of the forging corresponds to the center of the upper surface of the lower punch.

[0011] Furthermore, a front positioning sensor is provided at the end of the linear guide rail near the lower punch, and a rear positioning sensor is provided at the end of the linear guide rail away from the lower punch; the front positioning sensor and the rear positioning sensor are used to detect the position of the slider; the front positioning sensor and the rear positioning sensor are connected to a controller, the controller controls the telescopic drive source, and the controller also controls the pressure drive source on the pressure equipment that drives the upper die to rise and fall.

[0012] Furthermore, a protective cover is connected to the mounting plate. The protective cover includes a U-shaped protective plate with its opening facing downwards. The U-shaped protective plate includes two parallel and facing wing plates and a top plate connected to the upper end of the two wing plates. A bolt passes downwards through the positioning plate and is threaded onto the slider. A vertical sleeve is provided between the positioning plate and the slider, and the bolt thread passes through the vertical sleeve. The two wing plates are located on both sides of the linear guide rail and the slider. The top plate is located above the slider. A clearance groove extending along the length of the linear guide rail is provided on the top plate. The vertical sleeve passes through the clearance groove, and the positioning plate is located above the top plate.

[0013] Furthermore, the U-shaped protective plate extends along the length of the linear guide rail, and an end cap is connected to the end of the U-shaped protective plate facing the lower punch.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This utility model's forging blank positioning structure uses a retractable positioning plate to position the forging placed on the lower punch. In use, it can be controlled by a controller. When placing the forging, the telescopic drive source drives the positioning plate forward to directly above the lower punch. The forward positioning sensor can sense the position of the slider. The heated forging is manually placed on the lower die and close to the free end of the positioning plate to achieve positioning. The controller controls the telescopic drive source to drive the positioning plate backward, away from the position above the lower punch and away from the lower punch. The rear positioning sensor can sense the position of the slider. After the backward movement is completed, the controller then controls the pressure drive source to drive the upper die to descend and apply pressure to the forging.

[0016] The retractable positioning plate enables the positioning of the forging placed on the lower punch without interfering with the lowering and pressing of the upper die. It is safe and reliable to use, and can improve the consistency of the pressing and forming of the initial forging blank, thereby improving manufacturing quality and efficiency.

Detailed Implementation

[0023] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0024] Please see Figures 1-3 The forging blank positioning structure of a specific embodiment includes a pressure device, which includes a lower die base 1. A lower punch 2 is fixedly connected to the lower die base 1. The upper surface of the lower punch 2 is higher than the upper surface of the lower die base 1. The upper surface of the lower punch 2 is a plane to facilitate the placement of the forging. A mounting plate 3 is also fixedly connected to the lower die base 1, and a linear guide rail 4 and a telescopic drive source 6 are fixedly connected to the mounting plate 3. A slider 5 is slidably fitted on the linear guide rail 4. The telescopic drive source 6 drives the slider 5 to reciprocate along the linear guide rail 4 to move closer to or away from the lower punch 2. A positioning plate 7 is provided on the slider 5. One end of the positioning plate 7 is fixedly connected to the slider 5, and the free end of the positioning plate 7 extends toward the lower punch 2 and forms a positioning part.

[0025] When the slider 5 approaches the lower punch 2, the free end of the positioning plate 7 is located directly above the lower punch 2 in order to position the forging.

[0026] When the slider 5 moves away from the lower punch 2, the free end of the positioning plate 7 moves away from directly above the lower punch 2 and away from the lower punch 2, so as to make way for the upper die (not shown in the figure) of the pressure device to descend and apply pressure to the forging.

[0027] Please continue reading Figure 1 A front positioning sensor 8 is provided at the end of the linear guide rail 4 near the lower punch 2, and a rear positioning sensor 9 is provided at the end of the linear guide rail 4 away from the lower punch 2; the front positioning sensor 8 and the rear positioning sensor 9 are used to detect the position of the slider 5. Please refer to [link / reference]. Figure 5 The front positioning sensor 8 and the rear positioning sensor 9 are connected to the controller, which controls the telescopic drive source 6. The controller also controls the pressure drive source on the pressure equipment that drives the upper mold to rise and fall.

[0028] The positioning structure of this embodiment uses a retractable positioning plate 7 to position the forging 100 placed on the lower punch 2. In use, it can be controlled by a controller. When placing the forging 100, the retractable drive source 6 drives the positioning plate 7 forward to directly above the lower punch 2. The forward positioning sensor 8 senses the position of the slider 5. The heated forging 100 is then manually placed on the lower die and positioned close to the free end of the positioning plate 7, thus achieving positioning. (See also...) Figure 3 The controller controls the telescopic drive source 6 to drive the positioning plate 7 to retract, moving it away from the position above and away from the lower punch 2. The rear positioning sensor 9 can sense the position of the slider 5. After retracting to the correct position (see [reference]). Figure 4 The controller then controls the pressure drive source to drive the upper die to descend and apply pressure to the forging. Understandably, the lower surface of the upper die needs a recessed portion to allow the positioning plate 7 to retract into place, but this does not affect the protrusion that applies pressure to the forging. The retractable positioning plate 7 achieves positioning of the forging 100 placed on the lower punch 2 without interfering with the descent and pressure application of the upper die. This ensures safe and reliable use, improves the consistency of the initial forging blank's pressing and forming, and enhances manufacturing quality and efficiency.

[0029] After the initial forging blank is pressed, the controller controls the pressure drive source to drive the upper die to rise, and then controls the telescopic drive source 6 to drive the positioning plate 7 to move forward to the positioning point. The forward positioning sensor 8 can sense the position of the slider 5. After the initial forging blank is removed, the next forging 100 is placed, and this cycle continues. In practice, depending on the different pressing morphologies of the initial forging blanks, some pressed initial forging blanks may be difficult to remove, especially after the positioning plate 7 moves forward to the positioning point, which may obstruct the removal of the initial forging blank. In this case, it is not necessary to use the aforementioned linkage control of the controller. A forward movement control switch can be added. Please refer to [link to relevant documentation]. Figure 5It can be placed beside the pressure equipment, in a convenient location for the operator's feet. After the initial forging blank is pressed, the controller controls the pressure drive source to drive the upper die to rise. The initial forging blank is first manually removed, then the operator steps on the forward control switch, and the controller then controls the telescopic drive source 6 to drive the positioning plate 7 forward to the positioning point. This control process is only an example and not a limitation. For example, the telescopic drive source 6 can be a telescopic cylinder, and the switching valve of the telescopic cylinder can be controlled manually or by the controller.

[0030] Please continue reading Figure 1 and Figure 3 The positioning plate 7 is parallel to the upper surface of the lower mold base 1. The free end of the positioning plate 7 is recessed with a V-shaped groove 71, which faces the lower punch 2 and forms the positioning part.

[0031] The upper surface of the lower punch 2 is circular, and the forging 100 is cylindrical;

[0032] When the slider 5 is close to the lower punch 2 and the V-shaped groove 71 of the positioning plate 7 is located directly above the lower punch 2 for positioning, the outer circumferential side of the forging 100 abuts against the two inner side walls of the V-shaped groove 71, and the center of the forging 100 corresponds to the center of the upper surface of the lower punch 2 and is coaxial.

[0033] In this way, the cylindrical forging 100 is placed vertically on the upper surface of the lower punch 2, and the outer circumferential side abuts against the two inner side walls of the V-shaped groove 71. Compared with abutting only against the free end face of the positioning plate 7, the positioning is more accurate and reliable.

[0034] Please continue reading Figures 2-4 The mounting plate 3 is connected to a protective cover, which includes a U-shaped protective plate 10 with its opening facing downwards. The U-shaped protective plate 10 includes two parallel and facing wing plates and a top plate connected to the upper end of the two wing plates. A bolt passes freely downwards through the positioning plate 7 and is threadedly connected to the slider 5. A vertical sleeve is provided between the positioning plate 7 and the slider 5. The bolt thread passes through the inner hole of the vertical sleeve. After the bolt is tightened, the head of the bolt presses against the upper surface of the positioning plate 7, pressing the positioning plate 7 and the sleeve tightly connected to the slider 5. The two wing plates of the U-shaped protective plate 10 are located on both sides of the linear guide rail 4 and the slider 5. The top plate of the U-shaped protective plate 10 is located above the slider 5. A clearance groove 12 extending along the length of the linear guide rail 4 is provided on the top plate. The position and extension length of the clearance groove 12 correspond to the stroke of the slider 5 to avoid interfering with the reciprocating sliding of the slider 5. The vertical sleeve passes through the clearance groove 12, and the positioning plate 7 is located above the top plate. The U-shaped protective plate 10 extends along the length of the linear guide rail 4, covering the linear guide rail 4 and the telescopic drive source 6. An end sealing plate 11 is connected to one end of the U-shaped protective plate 10 facing the lower punch 2.

[0035] This helps to protect the positioning structure as much as possible and extend its service life.
