Description

Technical Field

[0001] This invention belongs to the field of forging presses and relates to the clamping mechanism of forging presses, specifically to a universal clamping mechanism for automatic forging presses. Background Technology

[0002] Automatic forging presses, as one of the main manufacturing equipment for fasteners, irregular parts and rolling elements, have significant advantages such as high production efficiency and material utilization, good product quality and stability, and low energy consumption and cost. Therefore, they are widely used in industries such as electronics and information, instrumentation, transportation, light industry, home appliances, aerospace and weaponry. It can be said that automatic forging presses play a vital role in national production.

[0003] As a core functional component of automatic forging presses, the clamping mechanism directly impacts the equipment's production efficiency. In the cold forging process, the clamping mechanism plays a crucial role in accurately transferring the workpiece between various workstations. However, existing automatic forging press clamping mechanisms generally suffer from functional limitations. Firstly, the positions of the flipping and translating clamps are fixed, requiring tools to assist in moving and rotating the workpiece. Secondly, the flipping and translating clamps often employ fixed combinations, making flexible configuration based on deformation process requirements impossible. This rigid design not only limits the optimization space for process solutions but also prevents the full release of equipment capacity, severely restricting the production efficiency and machining accuracy of complex parts. Summary of the Invention

[0004] To address the aforementioned technical deficiencies, this invention provides a universal clamping mechanism for an automatic forging press. The clamp frame, through a parallelogram structure formed by the first swing arm and the clamp base fixing plate, drives the synchronous swinging of the translational clamp and the flipping clamp, achieving workpiece position transfer and angular rotation. The modular design allows users to flexibly combine clamp modules according to process requirements, significantly improving machine tool utilization and precisely matching diverse production needs.

[0005] The technical solution adopted in this invention is as follows: An automatic forging press universal clamping mechanism is provided, including a machine tool and a clamping frame mounted on the machine tool. A clamping base fixing plate is arranged parallel to the front of the clamping frame. Both ends of the clamping base fixing plate are hinged to the clamping frame via first swing arms. A crossbeam is provided between the clamping base fixing plate and the clamping frame, and both ends of the crossbeam are connected to the first swing arms via rotating joints. At least one gear frame is fixedly installed on one side of the top surface of the crossbeam. The gear frame extends above the clamping base fixing plate and is fixedly mounted with a drive gear. At least one positioning shaft is rotatably mounted on the crossbeam, and a second swing arm is rotatably hinged to each positioning shaft. One end of the second swing arm extends to the top surface of the clamping frame and is driven to lift and lower via a reciprocating drive assembly. The other end extends to the top surface of the clamp base fixing plate; a drive linkage is hinged to one side of the clamp base fixing plate, and a flip clamp base corresponding to the number of gear frames and a translation clamp base corresponding to the number of positioning shafts are fixedly installed on the front side of the clamp base fixing plate; a drive shaft is rotatably installed on the flip clamp base, and flip clamp bases extend from both ends of the drive shaft respectively; a driven gear is fitted on the top of the drive shaft, and the driven gear meshes with the drive gear; a connecting seat is fixedly installed at the bottom of the drive shaft, and a flip clamp is installed on the connecting seat; a connecting shaft slides vertically inside the translation clamp base, and the top of the connecting shaft passes through the translation clamp base and is hinged to the second swing arm by means of a bushing; a connecting plate is hinged to the bottom of the connecting shaft, and a translation clamp is rotatably hinged on the connecting plate.

[0006] The clamp frame maintains stability through the parallelogram structure formed by the first swing arm and the clamp base fixing plate, ensuring the smooth swing of the clamp base fixing plate. Furthermore, the drive linkage pulls the clamp base fixing plate to swing precisely along a preset trajectory, ensuring perfect matching between the mechanism's motion and the forging process. Both the translation clamp and the flip clamp are initially closed. The translation clamp is driven to open and close by a reciprocating drive assembly to clamp the workpiece. When the clamp base fixing plate is driven to swing by the drive connecting rod, the translation clamp transfers the workpiece from one station to the next, realizing the workpiece transfer operation and release. When the workpiece is transferred to the flip clamp, it is clamped. Similarly, when the clamp base fixing plate is driven to swing by the drive connecting rod, the drive gear on the crossbeam and the driven gear on the drive shaft mesh and transmit power, so that the drive shaft drives the flip clamp to complete a 180° flip, completing the rotation of the workpiece. The modular design of the translation clamp and the flip clamp can meet different deformation process requirements, and its installation and adjustment are convenient and quick, with low cost. It improves the utilization rate of machine tools, expands the range of parts, and improves the automation level of forging production, while ensuring process accuracy and equipment reliability.

[0007] To further optimize this technical solution, the reciprocating drive assembly includes a corresponding number of cylinders and a third swing arm. The cylinders are fixedly installed on the clamp frame, and the third swing arm is installed on the clamp frame by means of a bracket. The bracket is fixedly installed on the back of the clamp frame, and the third swing arm is rotatably hinged to the bracket. One end of the third swing arm abuts against the cylinder output shaft, and the other end is driven by the cam drive mechanism.

[0008] The reciprocating drive assembly, consisting of a cylinder and a third swing arm, has a simple and reliable structure. It achieves automatic opening and closing of the translational clamp through mechanical linkage, while utilizing the leverage effect of the third swing arm to amplify the driving force to ensure stable clamping. Furthermore, the cylinder drive has a fast response, ensuring reliable operation.

[0009] To further optimize this technical solution, the cam drive mechanism includes a camshaft located on the rear side of the clamp frame. Both ends of the camshaft are mounted on the machine tool with the aid of supports and are connected to the power structure for drive. A cam corresponding to the number of third swing arms is fixedly mounted on the camshaft, and the cam abuts against the third swing arms.

[0010] By controlling the motion trajectory of the cam drive mechanism, the opening and closing sequence of the translation clamp is synchronized with the forging process. The camshaft is fixed by the support, ensuring smooth operation and minimal wear. The cams on the camshaft can be replaced according to process requirements, ensuring adaptability.

[0011] To further optimize this technical solution, the machine tool is also provided with a mounting shaft. The mounting shaft is located on the back of the clamp frame, and its two ends are fixedly installed with the machine tool by means of supports and driven by the drive structure. The mounting shaft is also fixedly installed with the bracket.

[0012] The mounting shaft provides rigid support for the entire clamping mechanism, ensuring stability during the lifting and lowering process. The mounting shaft is connected to the drive structure, enabling overall height adjustment, which facilitates equipment maintenance and process adjustment.

[0013] To further optimize this technical solution, the drive structure includes a motor fixedly mounted on the machine tool by means of a motor bracket, a torque limiter is mounted on the output shaft of the motor, a worm is coaxially mounted on the output end of the torque limiter, and a worm wheel that meshes with the worm is coaxially mounted with the mounting shaft.

[0014] The clamping mechanism is driven by a motor to lift and lower. The motor is easy to automate. The torque limiter on the motor provides overload protection to prevent damage to the drive structure. The motor is driven by a worm gear, which has a self-locking feature and can precisely control the lifting and lowering of the clamping mechanism as well as its position holding.

[0015] To further optimize this technical solution, the flip clamp includes two vertically arranged flip clamp bodies, which are respectively hinged to both sides of the connecting seat. The bottom of both flip clamp bodies extends to below the bottom surface of the connecting seat, and the top of the two flip clamp bodies are connected by an elastic member.

[0016] The two flip-up jaws provide clamping force for the workpiece, and the elastic component keeps the flip-up jaws closed, ensuring that the workpiece is reliably clamped. Its structure is simple, stable in use, and easy to maintain, thus improving the economic efficiency of use.

[0017] To further optimize this technical solution, the elastic component includes a spring disposed within the connecting seat, with both ends of the spring abutting against the flipping clamp body.

[0018] The spring built into the connector provides a constant preload to the flipping clamp body, keeping it closed and ensuring the clamping force on the workpiece. The spring's cushioning effect can adapt to workpieces of different sizes and specifications, ensuring the versatility of the flipping clamp body.

[0019] To further optimize this technical solution, the translation clamp includes two swing arms that are movably connected. Both swing arms are rotatably mounted in the translation clamp seat by means of a shaft, and the shafts extend out of the front of the translation clamp seat and are connected to the translation clamp.

[0020] The linkage structure of the two swing arms ensures the synchronous operation of the translation clamp, ensuring the accuracy of the clamping position, and the installation method of the shaft reduces running resistance, reduces wear, and ensures stable operation.

[0021] To further optimize this technical solution, the translation clamp includes cross-arranged translation clamp bodies, which are respectively fixedly fitted to the shaft body, and each translation clamp body has a clamp claw fixedly installed at its end.

[0022] The cross structure of the translation jaws increases the clamping range, and the replaceable design of the jaws can be adapted to workpieces of different shapes by changing the jaws. The rigid connection between the jaws and the translation jaws ensures more direct force transmission and avoids loosening of the clamps.

[0023] To further optimize this technical solution, the rotation radius of the first swing arm is R=L / 2sin22.5°, where L is the machine tool module spacing, and the center distance between the driving gear and the driven gear is R / 2, with a gear ratio of 3:1.

[0024] By precisely calculating the radius R of the first swing arm and the gear parameters, it is ensured that the flipping clamp can rotate accurately when the clamp seat fixing plate swings, ensuring that the motion trajectory fully matches the process requirements and guaranteeing the coordination and repeatability of the mechanism's motion.

[0025] The beneficial effects of this invention are as follows: 1. The clamp frame forms a stable parallelogram structure with the first swing arm and the clamp base fixing plate, ensuring the smooth swing of the clamp base fixing plate. The drive linkage drives the clamp base fixing plate to move along a preset trajectory. By precisely controlling the rotation radius of the first swing arm, the swing amplitude is precisely controlled, ensuring the perfect match between the mechanism movement and the forging process. 2. When the cam drive mechanism is activated, the distal end of the cam pushes the third swing arm to compress the cylinder, the second swing arm pulls the connecting shaft to rise, and drives the cross-translation clamp to close and clamp the workpiece. Meanwhile, the drive linkage drives the clamp seat fixing plate to swing, so that the translation clamp transfers the workpiece. When the cam rotates to the proximal end, the cylinder resets, the connecting shaft descends, and the translation clamp opens to unload the workpiece. The operation is smooth and flexible. 3. The drive gear and driven gear are matched with a 3:1 transmission ratio. When the clamp base plate swings 45°, the drive shaft drives the flip clamp to complete a 180° flip, realizing the workpiece flipping operation. The spring built into the connecting seat keeps the flip clamp closed, ensuring stable clamping of the workpiece during the flipping process. 4. The modular design of the translation clamp and the flip clamp can meet the needs of different deformation processes. They are easy and quick to install and adjust, low in cost, improve the utilization rate of machine tools, expand the range of parts to be manufactured, and improve the automation level of forging production, while ensuring process accuracy and equipment reliability.

Detailed Implementation

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0029] Please see the appendix Figure 1-7 The universal clamping mechanism of the automatic forging press includes a machine tool 1, a clamping frame 2 is provided on the machine tool 1, a clamping base fixing plate 3 is provided parallel to the front of the clamping frame 2, the two ends of the clamping base fixing plate 3 are respectively hinged to the clamping frame 2 by means of the first swing arm 4, the clamping frame 2, the clamping base fixing plate 3 and the first swing arm 4 form a parallelogram structure, one side of the clamping base fixing plate 3 is connected to the drive linkage 301 through a rotating joint, the drive linkage 301 drives the swing arm through the double cam 1501 to drive the clamping base fixing plate 3 to swing symmetrically within a range of 45°, the rotation radius of the first swing arm 4 is R=L / 2sin22.5°, where L is the die spacing of the machine tool 1, the front of the clamping base fixing plate 3 is fixedly installed with a translation clamp 12 seat 10, and the side of the front is fixedly installed with a flip clamp 11 seat 9; The translation clamp 12 base 10 is hollow inside, with a connecting shaft 1001 sliding vertically inside. The top of the connecting shaft 1001 extends out of the translation clamp 12 base 10, and a connecting plate 1002 is hinged to the bottom of the connecting shaft 1001. A translation clamp 12 is hinged to the connecting plate 1002. The translation clamp 12 includes two swing arms 1201 that are movably connected. The two swing arms 1201 are rotatably mounted inside the translation clamp 12 base 10 via the shaft 1202. The shafts 1202 all protrude from the front of the translation clamp 12 seat 10 and are connected to the translation clamp. The translation clamp includes translation clamp bodies 1203 arranged in a cross pattern. The translation clamp bodies 1203 are fixedly mounted to the shafts 1202 respectively, and the ends of the translation clamp bodies 1203 are fixedly installed with jaws 1204. By driving the connecting shaft 1001 to reciprocate up and down on the translation clamp 12 seat 10, the translation clamp opens and closes repeatedly to clamp the workpiece. A drive shaft 901 is rotatably mounted on the flip clamp 11 seat 9. The two ends of the drive shaft 901 extend out of the flip clamp 11 seat 9. A connecting seat 903 is fixedly mounted on the bottom of the drive shaft 901. The flip clamp 11 is mounted on the connecting seat 903. The flip clamp 11 includes two vertically arranged flip clamp bodies 1101. The two flip clamp bodies 1101 are respectively hinged to both sides of the connecting seat 903. The bottom of the two flip clamp bodies 1101 extends to the bottom surface of the connecting seat 903. The tops of the two flip clamp bodies 1101 are connected by an elastic member. The elastic member can be a spring 1102 disposed in the connecting seat 903. The two ends of the spring 1102 abut against the flip clamp bodies 1101 respectively. The spring 1102 keeps the flip clamp bodies 1101 closed so as to keep the workpiece in a clamped state and flip the workpiece through the drive shaft 901. The flip clamp 11 is driven by a gear frame 6 fixedly installed on one side of the top surface of the crossbeam 5. The number of vertical beams of the gear frame 6 corresponds to the number of flip clamps 11. The gear frame 6 extends above the clamp base fixing plate 3 and is fixedly installed with a drive gear 601. A driven gear 902 is fixedly mounted on the top of the drive shaft 901. The driven gear 902 meshes with the drive gear 601. The center distance between the drive gear 601 and the driven gear 902 is R / 2, and the gear ratio is 3:1. When the drive linkage 301 drives the clamp base fixing plate 3 to reciprocate, it causes the driven gear 902 to mesh with the drive gear 601, thereby driving the flip clamp 11 to rotate 180°. The translation clamp 12 can be driven by a reciprocating drive assembly to drive the connecting shaft 1001 to reciprocate within the translation clamp 12 seat 10. The reciprocating drive assembly can be a cylinder 13 and a reset component for reciprocating drive. The cylinder 13 is fixedly mounted on the clamp frame 2. The reset component includes a third swing arm 14 mounted by a bracket 201. The bracket 201 is fixedly mounted on the back of the clamp frame 2. The third swing arm 14 is hinged to the bracket 201. One end of the third swing arm 14 abuts against the cylinder output shaft 1301, and the other end is driven by a cam 1501 drive mechanism. The cam 1501 drive mechanism includes components located on the rear side of the clamp frame 2. The camshaft 15 is mounted on the machine tool 1 at both ends by means of the support 1502 and is connected to the power structure for drive. The camshaft 15 is fixedly fitted with cams 1501 corresponding to the position and number of the third rocker arm 14. The cams 1501 abut against the third rocker arm 14. After the distal end of the cam 1501 contacts the third rocker arm 14, it pushes the cylinder output shaft 1301 into the cylinder 13. After the proximal end contacts the third rocker arm 14, the third rocker arm 14 is unrestrained and the cylinder output shaft 1301 is pushed out, thereby causing the output shaft to move back and forth. The cylinder 13 is convenient for adjusting the force of the spring 1102, and has good flexibility and low noise. Cylinder 13 is driven to connect to connecting shaft 1001 via second swing arm 8. Second swing arm 8 is mounted on crossbeam 5 via positioning shaft 7, which is rotatably mounted to crossbeam 5. Positioning shaft 7 protrudes from the top surface of crossbeam 5 and is hinged to crossbeam 5. Both ends of second swing arm 8 extend above clamp seat fixing plate 3 and clamp frame 2, respectively. Both ends of second swing arm 8 are hinged to cylinder output shaft 1301 and connecting shaft 1001 via bushings 1003, thereby driving connecting shaft 1001 to reciprocate. The side wall is also provided with a buffer pad 1004, which is fixedly connected to the bottom surface of the translation clamp 12 seat 10 to reduce the contact and collision wear between the bushing 1003 and the translation clamp 12 seat 10. The positioning shaft 7 is rotated and mounted on the crossbeam 5. When the clamp seat fixing plate 3 is driven to move back and forth, the crossbeam 5 also moves with the clamp seat fixing plate 3. The second swing arm 8 is rotated by the connecting shaft 1001. The two ends of the second swing arm 8 are always connected to the cylinder output shaft 1301 and the connecting shaft 1001 to ensure the reliability of use. The machine tool 1 is also equipped with a mounting shaft 202, which is located on the back of the clamp frame 2. Both ends of the mounting shaft 202 are fixedly mounted to the machine tool 1 by means of the support 1502. One end of the mounting shaft 202 is driven and mounted to the drive structure, and the bracket 201 on the clamp frame 2 of the mounting shaft 202 is fixedly mounted. The drive structure includes a motor 1601 fixedly mounted on the machine tool 1 by means of the motor 1601 bracket 16201. A torque limiter 1602 is mounted on the output shaft of the motor 1601. A worm gear 2021 is fixedly mounted on the output shaft of the torque limiter 1602. The worm 1603 that meshes with the worm gear 2021 is coaxially mounted with the mounting shaft 202. When the motor 1601 is running, it drives the entire clamping mechanism to lift or lower, which is convenient for adjustment and maintenance.

[0030] The working principle of the universal clamping mechanism of the automatic forging press is as follows: The clamp frame 2 is kept stable by the parallelogram structure formed by the first swing arm 4 and the clamp base fixing plate 3, ensuring that the clamp base fixing plate 3 swings smoothly within a 45° range. The drive linkage 301 moves according to a preset trajectory under the drive of the double cam 1501 mechanism. The rotation radius R=L / 2sin22.5° of the first swing arm 4 is precisely controlled, where L represents the die spacing of the machine tool, ensuring precise control of the swing amplitude and perfect matching between the mechanism movement and the forging process. When the mechanism is running, both the translation clamp 12 and the flip clamp 11 are closed. When the cam 1501 drive mechanism is started, the distal end of the cam 1501 pushes the third swing arm 14, which in turn compresses the cylinder 13, causing the second swing arm 8 to drive the connecting shaft 1001 to rise. Through the linkage of the connecting plate 1002, the cross-set translation clamp 12 closes to clamp the workpiece. When the clamp base fixing plate 3 is driven to swing by the driving connecting rod, the translation clamp 12 transfers the workpiece from one station to the next, realizing the workpiece transfer operation. When the cam 1501 rotates to the proximal end, the cylinder 13 resets, and the clamp body opens to release the workpiece. After the workpiece is transferred to the flip clamp 11, it clamps the workpiece. The drive gear 601 and driven gear 902 of the flip clamp 11 are matched with a 3:1 transmission ratio. When the clamp base fixing plate 3 swings 45°, the drive shaft 901 drives the flip clamp 11 to complete a 180° flip. The built-in spring 1102 mechanism ensures stable clamping of the workpiece during the flipping process. The modular design of the translation clamp 12 and the flip clamp 11 can meet different deformation process requirements. They are easy and quick to install and adjust, low in cost, improve the utilization rate of the machine tool 1, expand the range of parts, and improve the automation level of forging production, while ensuring process accuracy and equipment reliability.
