Description

Technical Field

[0001] This utility model relates to the field of mechanical processing technology, specifically to a positioning and adjusting type stamping die for mechanical parts. Background Technology

[0002] Stamping dies are widely used in the machining of mechanical parts, and their positioning and adjustment functions have a significant impact on machining accuracy and efficiency. However, most stamping dies on the market currently use fixed positioning structures or simple adjustment mechanisms, which make it difficult to achieve rapid and accurate positioning adjustments when dealing with workpieces of different sizes and specifications. This results in problems such as low production efficiency, complex operation, and unstable machining accuracy.

[0003] A search revealed a stamping die with patent number CN106541029B, published on April 6, 2018. This design, by setting a slider and a first adjusting screw on the stripper plate, allows for adjustment of the horizontal position of the insert in the groove, thereby adjusting the punch offset. While this structure satisfies the positioning adjustment requirement to some extent, its adjustment method relies on manually turning the screw, making the process cumbersome. Furthermore, the adjustment accuracy is easily affected by human factors, making it difficult to achieve rapid and precise multi-point synchronous adjustment. In addition, this structure lacks an effective locking mechanism, and displacement may occur due to vibration during stamping, thus affecting the processing quality.

[0004] A search revealed a mold with patent number CN104107862B, published on April 20, 2016. This design features inclined push blocks and sliding positioning blocks on both the punch and die. During the downward movement of the punch, the inclined push blocks and sliding positioning blocks press against each other, causing the two sliding positioning blocks to move relative to each other, thus achieving the positioning of the stamped workpiece. This structure can achieve automatic positioning during the stamping process, but its positioning range is limited, only applicable to workpieces of specific shapes, and its versatility is poor. Furthermore, because its positioning force is derived from the pressure transmission of a hydraulic device, its positioning stability is low, and positioning deviations may occur during continuous high-speed stamping, thereby affecting product quality.

[0005] The aforementioned problems indicate that traditional stamping dies currently on the market have limitations in their positioning and adjustment functions when facing the diverse and high-precision machining needs of mechanical parts, making it difficult to meet the requirements of efficient and stable use. Therefore, this utility model provides a positioning and adjustment type stamping die for mechanical parts, aiming to overcome the shortcomings of the existing technology and provide a more convenient, accurate, and adaptable solution. Utility Model Content

[0006] This utility model provides a positioning and adjustment type stamping die for mechanical parts, aiming to overcome the problem of insufficient positioning and adjustment function in existing stamping dies. The specific solution is as follows:

[0007] A positioning and adjusting mechanical part stamping die includes a base, a sliding frame, and a positioning mechanism, and also includes a driving device connected to the sliding frame. The sliding frame is mounted on the top of the base via a guide rail and can move horizontally along the guide rail. Two sets of telescopic adjusting arms are symmetrically arranged on both sides of the sliding frame, and a positioning block is installed at the end of each set of adjusting arms. The positioning blocks of the two sets of adjusting arms are arranged opposite each other and on the same horizontal plane. Multiple elastic clamping elements are provided on the inner side of the positioning blocks, which are used to clamp the edge of the workpiece. The two sets of adjusting arms can move towards each other or away from each other in the horizontal direction under the drive of the sliding frame, thereby adjusting the distance between the positioning blocks to accommodate workpieces of different sizes.

[0008] As a preferred embodiment, a drive shaft is installed in the middle of the sliding frame and arranged perpendicularly thereto, with both ends of the drive shaft extending to the outside of the sliding frame respectively; rotatable gears are installed at both ends of the drive shaft; the gears are located between the two sets of adjusting arms and mesh with the racks on the adjusting arms, and the rotation of the gears is used to drive the two sets of adjusting arms to move synchronously on the sliding frame.

[0009] Furthermore, guide sleeves with downward openings are installed on the middle of both sides of the sliding frame. A piston rod is installed inside the guide sleeve. A first reset member is provided inside the guide sleeve. One end of the first reset member is fixedly connected to the top inner wall of the guide sleeve, and the other end is fixedly connected to the top end of the piston rod. A connecting rod is installed at the bottom end of the piston rod. A through hole is provided through the top of the sliding frame along its thickness direction. An auxiliary positioning block is installed at one end of the connecting rod after passing through the through hole.

[0010] In addition, the bottom of the adjusting arm is equipped with multiple airflow channels, the number of which corresponds to the elastic clamping member; the outlet of the airflow channel faces downward of the elastic clamping member; the multiple airflow channels are connected to the top of the guide sleeve by a flexible hose.

[0011] Furthermore, a tee connector is installed on the top of the sliding frame, located on one side of the guide sleeve; the top interface of the tee connector is connected to an external negative pressure device via a hose; the bottom interface of the tee connector is connected to an auxiliary positioning block via a hose; one side interface of the tee connector faces the connecting rod, and a sealing rod is installed laterally inside one side of the tee connector, with a limiting plate located outside the connecting rod installed at the end of the sealing rod.

[0012] Preferably, the rod portion of the sealing rod is sleeved with a second reset member, and the second reset member is located between one end face of the tee connector and the limiting plate.

[0013] In addition, a flexible gasket is attached to the outer wall of the connecting rod away from the tee joint, and the flexible gasket is arranged along the length of the connecting rod.

[0014] Furthermore, a pull rod is rotatably mounted on the top of the sliding frame, and the outer wall of the pull rod is in contact with the top surface of the sliding frame; one end of the pull rod is always connected to the end of the adjusting arm.

[0015] Meanwhile, a driven wheel, coaxial with the gear, is mounted on the top of the drive shaft; the driven wheels are connected by a synchronous belt; and a power device for driving the synchronous belt drive is provided above the sliding frame.

[0016] Finally, a groove is provided at the top of the adjusting arm along its length, and the groove is slidably connected to the guide rail on the sliding frame.

[0017] Compared with the prior art, the present invention has at least the following characteristics:

[0018] This device features an adjustable arm that can move horizontally towards or away from each other under the drive of the sliding frame. The positioning block and elastic clamping element installed at its end enable the positioning of the workpiece. It is suitable for processing workpieces of different sizes and has strong versatility.

[0019] This device uses a gear and rack meshing structure. The gear can not only drive the two sets of adjusting arms to move synchronously, but also form a locking effect when the workpiece shakes or stops suddenly during processing, preventing the adjusting arms from sliding on the sliding frame and thus ensuring the stability of the workpiece positioning.

[0020] The device, through the design of the auxiliary positioning block, can assist in clamping the workpiece in the middle, thereby improving the reliability of workpiece positioning. At the same time, it works in conjunction with the first reset component to pre-position the workpiece surface before clamping.

[0021] The device uses a limiting plate design. When the elastic clamping component and the auxiliary positioning block adhere to the workpiece surface and form a stable clamping state, the limiting plate will adhere to the outer wall of the connecting rod to prevent the elastic clamping component from loosening due to external factors. After the workpiece is processed, the limiting plate will disengage from the connecting rod, and the connecting rod will drive the auxiliary positioning block to move downward under the action of the first reset component, thereby achieving the effect of automatic release.

[0022] The device uses a pull rod design, with one end of the pull rod fitting against the top of the sliding frame and the other end connected to the end of the adjusting arm, thereby providing support for the adjusting arm, reducing wear between the adjusting arm and the sliding frame, keeping the elastic clamping components at the bottom of the adjusting arm on the same horizontal plane, and ensuring that multiple elastic clamping components are in close contact with the workpiece surface during clamping, thus improving clamping stability.

[0023] The above technical solution, through specific structural design, solves the problem of insufficient positioning and adjustment function of stamping dies in the prior art, and realizes fast, accurate and stable positioning and adjustment function, meeting the needs of diversified and high-precision mechanical parts processing.

[0032] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0033] This utility model provides a positioning and adjusting type stamping die for mechanical parts, the structure of which is as follows: Figures 1 to 5As shown. The base 1 is the basic component of the entire device. The sliding frame 2 is mounted on the top of the base 1 via a guide rail 25. The guide rail 25 is arranged horizontally, allowing the sliding frame 2 to move horizontally on the guide rail 25. Two sets of adjusting arms 3 are symmetrically arranged on both sides of the sliding frame 2. The bottom of the adjusting arm 3 is provided with a sliding groove 24, which is slidably connected to the guide rail 25 on the sliding frame 2, thereby realizing the horizontal movement of the adjusting arm 3 on the sliding frame 2. A positioning block 4 is installed at the end of each set of adjusting arms 3. The positioning blocks 4 are arranged opposite each other and on the same horizontal plane. Multiple elastic clamping parts 5 are provided on the inner side of the positioning block 4. The elastic clamping parts 5 are used to clamp the edge of the workpiece.

[0034] A drive shaft 6 is mounted perpendicularly to the middle of the sliding frame 2. Both ends of the drive shaft 6 extend to the outer sides of the sliding frame 2, and gears 7 are mounted at both ends of the drive shaft 6. The gears 7 are located between two sets of adjusting arms 3 and mesh with racks 8 on the adjusting arms 3. The racks 8 are arranged along the length of the adjusting arms 3. When the drive shaft 6 rotates, the gears 7 rotate accordingly. Through the meshing relationship between the gears 7 and the racks 8, the two sets of adjusting arms 3 are driven to move horizontally towards or away from each other, thereby adjusting the distance between the positioning blocks 4 to accommodate workpieces of different sizes. A driven wheel 21 is mounted on the top of the drive shaft 6. The driven wheels 21 are connected by a synchronous belt 22. A power unit 23 is located above the sliding frame 2. The power unit 23 drives the driven wheels 21 to rotate by driving the synchronous belt 22, thereby realizing the rotation of the drive shaft 6.

[0035] Guide sleeves 9 with downward openings are installed on the middle of both sides of the sliding frame 2. A piston rod 10 is installed inside the guide sleeve 9. The top end of the piston rod 10 is fixedly connected to one end of the first reset member 11, and the other end of the first reset member 11 is fixedly connected to the top inner wall of the guide sleeve 9. A connecting rod 12 is installed at the bottom end of the piston rod 10. A through hole is provided through the top of the sliding frame 2 along its thickness direction. An auxiliary positioning block 13 is installed at one end of the connecting rod 12 through the through hole. The auxiliary positioning block 13 is used to assist in clamping the workpiece in the middle, improving the reliability of workpiece positioning. When the workpiece is clamped by the elastic clamping member 5, the auxiliary positioning block 13 moves downward under the action of the first reset member 11, contacting the workpiece surface to form a pre-positioning effect. After processing is completed, the first reset member 11 drives the piston rod 10 and the connecting rod 12 to move upward, and the auxiliary positioning block 13 disengages from the workpiece surface.

[0036] Multiple airflow channels 14 are installed at the bottom of the adjusting arm 3, the number of which corresponds to the number of elastic clamping members 5. The outlets of the airflow channels 14 face downwards from the elastic clamping members 5. The multiple airflow channels 14 are connected to the top of the guide sleeve 9 via flexible hoses to form an airflow path. A three-way connector 15 is installed on the top of the sliding frame 2. The top interface of the three-way connector 15 is connected to an external negative pressure device via a flexible hose, and the bottom interface of the three-way connector 15 is connected to an auxiliary positioning block 13 via a flexible hose. One side interface of the three-way connector 15 faces the connecting rod 12. A sealing rod 16 is installed laterally inside the three-way connector 15. A limiting plate 17 is installed at the end of the sealing rod 16, and the limiting plate 17 is located outside the connecting rod 12. A second reset member 18 is sleeved on the rod part of the sealing rod 16, and the second reset member 18 is located between one side end face of the three-way connector 15 and the limiting plate 17. When the auxiliary positioning block 13 adsorbs the workpiece surface and forms a stable clamping state, the limiting plate 17 is attached to the outer wall of the connecting rod 12 to prevent the elastic clamping member 5 from loosening due to external factors. A flexible gasket 19 is attached to the outer wall of the connecting rod 12 away from the tee connector 15. The flexible gasket 19 is arranged along the length of the connecting rod 12 to protect the contact surface between the connecting rod 12 and the limiting plate 17.

[0037] A pull rod 20 is rotatably mounted on the top of the sliding frame 2. The outer wall of the pull rod 20 fits against the top surface of the sliding frame 2, and one end of the pull rod 20 is always connected to the end of the adjusting arm 3. The design of the pull rod 20 provides support for the adjusting arm 3, reducing wear between the adjusting arm 3 and the sliding frame 2, while ensuring that the elastic clamping member 5 at the bottom of the adjusting arm 3 always remains on the same horizontal plane. In actual operation, when the power unit 23 is started, the transmission shaft 6 drives the adjusting arm 3 to move horizontally through the engagement of the gear 7 and the rack 8. The pull rod 20 rotates with the movement of the adjusting arm 3, ensuring the stability of the adjusting arm 3.

[0038] In the specific operation, the workpiece to be processed is placed on top of the base 1, and the power unit 23 is started. The power unit 23 drives the driven wheel 21 to rotate via the synchronous belt 22. The driven wheel 21 drives the transmission shaft 6 to rotate. The rotation of the transmission shaft 6 causes the gear 7 to rotate. The gear 7 drives the two sets of adjusting arms 3 to move in opposite directions in the horizontal direction via the rack 8. The movement of the adjusting arms 3 causes the positioning block 4 to move closer to the workpiece. The elastic clamping member 5 on the positioning block 4 gradually clamps the edge of the workpiece. At the same time, the external negative pressure device applies negative pressure to the auxiliary positioning block 13 through the three-way connector 15. Under the action of the first reset member 11, the auxiliary positioning block 13 moves downward and contacts the surface of the workpiece, forming a pre-positioning effect. After the elastic clamping member 5 fully clamps the workpiece, the limiting plate 17 fits against the outer wall of the connecting rod 12 to prevent the elastic clamping member 5 from loosening. After processing, the power unit 23 reverses its rotation, and the gear 7 and rack 8 work together to move the adjusting arm 3 apart in the horizontal direction. The elastic clamping member 5 releases the workpiece, and the first reset member 11 drives the auxiliary positioning block 13 to move upward, thus completing the release of the workpiece.

[0039] The above embodiments describe in detail the specific structure and operating principle of this utility model. The specific drawings and component reference numerals in the drawings have been fully disclosed, enabling those skilled in the art to fully implement the technical solution based on the contents of the specification.

[0040] To enable those skilled in the art to fully understand and implement this utility model, the following supplementary explanation of the specific implementation principle of this utility model is provided in conjunction with a specific application scenario.

[0041] First, place the workpiece to be processed on top of the base 1, ensuring that the center of the workpiece is roughly aligned with the central axis of the sliding frame 2. Then, start the power unit 23. The power unit 23 drives the driven wheel 21 to rotate via the synchronous belt 22, which in turn drives the transmission shaft 6 to rotate. The rotation of the transmission shaft 6 causes the gear 7 to rotate accordingly. The meshing relationship between the gear 7 and the rack 8 drives the two sets of adjusting arms 3 to move towards each other in the horizontal direction. The movement of the adjusting arms 3 causes the positioning block 4 to move closer to the workpiece, and the elastic clamping element 5 on the positioning block 4 gradually clamps the edge of the workpiece. During this process, the design of the elastic clamping element 5 can adapt to the edges of workpieces of different shapes and sizes, thereby achieving a flexible clamping effect and avoiding surface damage to the workpiece caused by rigid clamping.

[0042] Meanwhile, the external negative pressure device applies negative pressure to the auxiliary positioning block 13 through the three-way connector 15. Under the action of negative pressure, the auxiliary positioning block 13 moves downward under the action of the first reset member 11 and contacts the workpiece surface, forming a pre-positioning effect. The design of the auxiliary positioning block 13 can effectively improve the positioning reliability of the workpiece, especially in terms of stability in the middle region of the workpiece. After the elastic clamping member 5 fully clamps the workpiece, the limiting plate 17 fits against the outer wall of the connecting rod 12 to prevent the elastic clamping member 5 from loosening due to external vibration or impact. This design, through the cooperation of the mechanical structure, achieves stable clamping of the workpiece during the stamping process, avoiding the positioning deviation problem caused by the lack of a locking mechanism in traditional molds.

[0043] In the above process, the design of the airflow channels 14 plays a crucial role. The number of airflow channels 14 corresponds one-to-one with the elastic clamping members 5, and their outlets face downwards towards the elastic clamping members 5. When the external negative pressure device is activated, the airflow path formed between the airflow channels 14 and the guide sleeve 9 can effectively enhance the adsorption force of the elastic clamping members 5, thereby further improving the clamping effect. In addition, the cooperative design of the sealing rod 16 and the limiting plate 17 inside the tee connector 15 can provide additional stability when the auxiliary positioning block 13 adsorbs the workpiece surface. The rod part of the sealing rod 16 is sleeved with the second reset member 18. After the auxiliary positioning block 13 completes adsorption, the limiting plate 17 tightly fits against the outer wall of the connecting rod 12, thereby preventing the elastic clamping members 5 from loosening due to external factors. A flexible gasket 19 is attached to the outer wall of the connecting rod 12 away from the tee connector 15. The design of the flexible gasket 19 can reduce the friction between the connecting rod 12 and the limiting plate 17, while protecting the contact surface and extending the service life.

[0044] The design of the pull rod 20 plays a crucial role in the movement of the adjusting arm 3. One end of the pull rod 20 is always connected to the end of the adjusting arm 3, while the other end rests against the top surface of the sliding frame 2. When the adjusting arm 3 moves horizontally, the pull rod 20 rotates along with it, which not only reduces direct wear between the adjusting arm 3 and the sliding frame 2 but also ensures that the elastic clamping member 5 at the bottom of the adjusting arm 3 remains on the same horizontal plane. This design effectively avoids uneven clamping caused by the tilting of the adjusting arm 3, thereby improving the accuracy and stability of workpiece positioning.

[0045] After the workpiece is processed, the power unit 23 reverses its rotation, and the transmission shaft 6, through the engagement of the gear 7 and rack 8, causes the adjusting arm 3 to move horizontally away from each other. As the adjusting arm 3 moves, the elastic clamping member 5 gradually releases the workpiece. At the same time, the first reset member 11 drives the piston rod 10 and connecting rod 12 to move upward, and the auxiliary positioning block 13 disengages from the workpiece surface, completing the release of the workpiece. The entire process requires no manual intervention, achieving automated operation and significantly improving production efficiency.

[0046] As can be seen from the above steps, this utility model achieves synchronous movement of the two sets of adjusting arms 3 through the meshing structure of gear 7 and rack 8, ensuring that the distance between the positioning blocks 4 can be quickly and accurately adjusted to adapt to workpieces of different sizes. Simultaneously, the cooperative design of the auxiliary positioning block 13 and the elastic clamping member 5 not only improves the reliability of workpiece positioning but also avoids the positioning deviation problem caused by vibration in traditional molds through negative pressure adsorption and mechanical limiting. Furthermore, the design of the pull rod 20 effectively reduces wear between the adjusting arm 3 and the sliding frame 2, ensuring the stability of the clamping process. These designs work together to solve the problem of insufficient positioning and adjustment functions in existing stamping dies, meeting the diverse and high-precision machining needs of mechanical parts.

[0047] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
