Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically a high-precision, fast-positioning continuous mold. Background Technology

[0002] Progressive die refers to a cold stamping die that uses several different stations on a single die to complete multiple stamping operations simultaneously. Each time the die completes a stamping operation, the workpiece moves a fixed distance once until all the workpiece has been processed. In this process, it is not necessary to transfer the workpiece between multiple sets of dies in different positions along complex routes. Only rapid positioning and movement in a straight line are required, which effectively avoids workpiece positioning deviation and improves workpiece processing accuracy.

[0003] When a workpiece with a rough surface is stamped on a progressive die, the workpiece is placed on the top surface of the fixed die. After the workpiece completes one pass on the progressive die, the pushing mechanism pushes the workpiece to a position under the limit of the moving track for continued processing. During this process, the bottom surface of the workpiece is in contact with the surface of the fixed die, which causes significant friction between them during the movement, resulting in wear on the workpiece. This wear leads to wear at the connection point between the workpiece and the fixed die, causing deformation of the workpiece's movement path on the fixed die. This affects the accurate processing of other workpieces on the progressive die in subsequent processes. To address the shortcomings of existing technologies, we propose a high-precision, rapid positioning progressive die to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a high-precision, rapid positioning progressive die. It solves the problem that when a workpiece moves on the surface of the fixed die in a progressive die, the bottom surface of the workpiece is in contact with the surface of the fixed die, resulting in significant friction and wear on the workpiece. This wear causes deformation of the workpiece's movement path on the fixed die, affecting the precise machining of other workpieces on the progressive die in subsequent stages.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-precision, rapid positioning continuous mold, comprising a lower mold plate, an upper mold plate, a telescopic guide rod, a fixed mold, a moving mold, and a hydraulic cylinder. The outer surface of the fixed mold is provided with a guiding mechanism, which includes:

[0006] A cavity is formed on the top surface of multiple sets of fixed molds. A guide post is provided inside the cavity, and a first guide roller and a second guide roller for rapid positioning of the workpiece are rotatably connected to the inner surface of the guide post.

[0007] The limiting seats are respectively fixedly installed on the bottom surface of a set of guide columns, and a connecting plate is fixedly connected to one end of the multiple sets of limiting seats extending to the outside of the fixed mold.

[0008] The lower control plate has one end slidably disposed outside the fixed mold, and one end of the lower control plate is slidably connected to the upper control plate which is fixedly connected to the side wall of the moving mold. The position of the connecting plate can be adjusted up and down by adjusting the positions of the lower control plate and the upper control plate.

[0009] Preferably, the outer wall of the fixed mold has a connecting hole that communicates with the interior of the cavity, one end of the limiting seat extends to the outside of the fixed mold through the connecting hole, and the bottom end of the lower control plate intermittently abuts against the bottom surface of the connecting plate.

[0010] Preferably, a telescopic rod is fixedly connected to the bottom surface of the lower control plate, a connecting groove is provided on the top surface of the fixed mold, and the other end of the telescopic rod is fixedly connected to the inner bottom surface of the connecting groove.

[0015] Preferably, the bottom surface of the moving mold has a connecting cavity corresponding to the cavity position.

[0016] This utility model discloses a high-precision rapid positioning progressive die, which has the following beneficial effects: This high-precision rapid positioning progressive die has guide pillars set on the fixed die, and two sets of guide rollers that can change the positioning range are rotatably connected inside the guide pillars. The two sides of the workpiece are positioned and moved between the two sets of guide rollers. In addition, combined with the lower control plate, upper control plate, connecting plate and telescopic rod, when the moving die moves up and down, it can simultaneously drive multiple sets of guide pillars to move up and down.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] This application provides a high-precision, fast-positioning progressive die, which solves the problem that when a workpiece moves on the surface of the fixed die of the progressive die, the bottom surface of the workpiece is in contact with the surface of the fixed die, resulting in significant friction and wear on the workpiece. This wear causes the connection between the workpiece and the fixed die to be affected, deforming the movement path of the workpiece on the fixed die and affecting the accurate processing of other workpieces on the progressive die later. This invention achieves lifting and conveying of the workpiece during the movement process.

[0028] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0029] This utility model discloses a high-precision, rapid positioning continuous mold.

[0030] According to the appendix Figure 1-7 As shown, the high-precision continuous die includes a lower template 1, an upper template 2, a telescopic guide rod 3 positioned between the lower template 1 and the upper template 2, a fixed mold 4 fixedly positioned on the top surface of the lower template 1, a movable mold 5 slidably positioned at the lower part of the upper template 2, and a hydraulic cylinder fixedly positioned on the top surface of the upper template 2 to drive the movable mold 5 to move up and down. The lower template 1, upper template 2, telescopic guide rod 3, multiple sets of fixed molds 4, multiple sets of movable molds 5, and hydraulic cylinders constitute a high-precision continuous die. When punching multiple workpieces, the workpiece is placed on the top surface of a set of fixed molds 4 from the loading end of the continuous die. Then, the hydraulic cylinder is activated to drive the multiple sets of movable molds 5 to move down, so that the workpiece is punched once. Then, the hydraulic cylinder is activated again to control the movable molds 5 to move up. Subsequently, through an externally set pushing device, such as an electric telescopic column, the workpiece that has completed one processing is pushed to the next set of fixed molds 4 for continued processing. The above operation is repeated so that the workpiece can be continuously processed at the continuous die. The pushing device is not specifically shown in the attached figure.

[0031] See attached document Figure 1-6The outer surface of the fixed mold 4 is provided with a guide mechanism 6. The guide mechanism 6 can lift the workpiece during the movement process to avoid large friction between the workpiece and the surface of the fixed mold 4, thereby accurately guiding the movement trajectory of the workpiece. The guide mechanism 6 includes a cavity 61. Multiple cavities 61 are respectively opened on the top surface of multiple fixed molds 4. Guide pillars 62 are provided inside the cavity 61. Two sets of guide pillars 62 are provided on one set of fixed molds 4. The two sets of guide pillars 62 are respectively located on both sides of the workpiece. The inner surface of the guide pillars 62 is rotatably connected to a first guide roller 63 and a second guide roller 64 for rapid positioning of the workpiece. The uppermost end of the outer wall of the first guide roller 63 is flush with the top surface of the fixed mold 4. One end of the bottom surface of the workpiece contacts the outer wall of the first guide roller 63. The outer wall of the second guide roller 64 abuts against the top surface of the workpiece. The bottom surface of the moving mold 5 is provided with a connecting cavity 9 corresponding to the position of the cavity 61, so that when the moving mold 5 is closed with the fixed mold 4, the guide pillars 62 will not obstruct the movement of the moving mold 5.

[0032] See attached document Figure 4-6 Multiple sets of limiting seats 65 are fixedly mounted on the bottom surface of a set of guide pillars 62, and a connecting plate 66 is fixedly connected to one end of the multiple sets of limiting seats 65 extending to the outside of the fixed mold 4. A connecting hole 611 communicating with the inside of the cavity 61 is opened on the outer wall of the fixed mold 4. One end of the limiting seat 65 extends to the outside of the fixed mold 4 through the connecting hole 611. One end of the lower control plate 67 is slidably mounted on the outside of the fixed mold 4. A telescopic rod 68 is fixedly connected to the bottom surface of the lower control plate 67. A connecting groove 681 is opened on the top surface of the fixed mold 4. The other end of 68 is fixedly connected to the inner bottom surface of the connecting groove 681, and one end of the lower control plate 67 is slidably connected to the upper control plate 69 which is fixedly connected to the side wall of the moving mold 5. The inner surface of the lower control plate 67 is fixedly connected to the limiting plate 8 for the directional sliding of the upper control plate 69. The lower control plate 67 and the upper control plate 69 are always connected. The bottom end of the lower control plate 67 intermittently abuts against the bottom surface of the connecting plate 66. The position of the connecting plate 66 can be adjusted up and down by adjusting the position of the lower control plate 67 and the upper control plate 69.

[0033] Specifically, after the workpiece completes one processing cycle at a set of fixed molds 4, it is conveyed to the next set of fixed molds 4 via a pushing device. At this time, the moving mold 5 and the fixed molds 4 are as shown in the attached figure. Figure 2 In this state, the hydraulic cylinder can be activated to control the moving mold 5 to move upward, causing the upper control plate 69, which is fixedly connected to the moving mold 5, to move accordingly. When the upper control plate 69 moves to a certain position, that is, when the bottom end of the upper control plate 69 is aligned with the attached... Figure 2 When the top of the lower control plate 67 abuts against the upper control plate 69 and the moving mold 5, the lower control plate 67 will move in the same direction as the upper control plate 69 and the moving mold 5, so that the bottom of the lower control plate 67 moves towards the connecting plate 66 under the positioning guide of the telescopic rod 68.

[0034] Next, when the moving mold 5 and the upper control plate 69 move to the position shown in the attached diagram... Figure 1 In the current state, the bottom end of the lower control plate 67 contacts the bottom end of the connecting plate 66, and lifts the connecting plate 66 upward, causing the multiple sets of guide columns 62, which are fixedly connected to the connecting plate 66 through the limiting seat 65, to move upward simultaneously. This causes the workpiece, which is limited between the two sets of guide rollers of the guide column 62, to be lifted, so that the bottom surface of the workpiece does not contact the top surface of the fixed mold 4. Subsequently, under the push of the pushing device, the workpiece moves and is loaded under the positioning and guidance of the two sets of guide rollers. Conversely, when the moving mold 5 and the upper control plate 69 move downward, the lifting force on the lower control plate 67 disappears. At this time, the lower control plate 67 moves downward under gravity, causing the lifting force on the connecting plate 66 to disappear. This causes the connecting plate 66 and the multiple sets of guide columns 62 connected to the connecting plate 66 to move downward, causing the workpiece, which is limited between the two sets of guide rollers of the guide column 62, to move downward. At this time, the bottom surface of the workpiece after being loaded abuts against the top surface of the fixed mold 4, so that the workpiece can continue to be processed.

[0035] See attached document Figure 7 An adjustment assembly 7 is provided inside the guide post 62. The adjustment assembly 7 is used to adjust the position of the second guide roller 64, that is, to stably clamp and limit the guidance of workpieces of different thicknesses. The adjustment assembly 7 includes an adjustment screw 71 rotatably disposed inside the guide post 62, a set of bearing seats 72 threadedly sleeved on the outer wall of the adjustment screw 71 and fixedly connected to one end of the second guide roller 64, and an auxiliary rod 73 fixedly disposed inside the guide post 62 for positioning the moving position of the bearing seats 72. The top surface of the guide post 62 has a hidden groove 74 for mounting the hand end of the adjustment screw 71. 71 The outer wall of the hand-held end is threaded with bolts. One end of the first guide roller 63 is fixedly connected to another set of bearing seats 72. The outer wall of the other set of bearing seats 72 is fixedly connected to the inner surface of the guide post 62. Through the setting of the bearing seats 72, it can be ensured that the first guide roller 63 and the second guide roller 64 are always in a rotating state and are set on the inner surface of the guide post 62. Specifically, by rotating the adjusting screw 71, under the action of the threaded connection between the adjusting screw 71 and the set of bearing seats 72, the second guide roller 64 can be driven to move up and down, thereby adjusting the distance between the second guide roller 64 and the first guide roller 63.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
