Description

Technical Field

[0001] The utility model relates to the technical field of stamping metal processing, in particular to a tooling fixture for stamping metal processing. Background Art

[0002] The tooling and fixtures for stamping metal processing are special fixtures used in the metal stamping process to fix and support metal workpieces to ensure that accurate shapes and sizes can be obtained during the stamping process. These tooling and fixtures play a key role in the stamping industry, improving production efficiency, ensuring product quality, and reducing the occurrence of human errors.

[0003] When clamping a workpiece, the existing tooling fixtures for stamping metal processing on the market generally need to set drive components on both ends of the workpiece, and then start the drive components on both sides at the same time for clamping. This makes the clamping operation cumbersome. For this reason, we propose a tooling fixture for stamping metal processing. Utility Model Content

[0004] The purpose of the utility model is to provide a tooling fixture for stamping metal processing to solve the problems raised in the above background technology.

[0025] like Figure 1-4 As shown, a technical solution provided by the utility model:

[0026] A tooling fixture for stamping metal processing, including a base 1, a clamping platform 2 is fixedly installed on the top of the base 1, a shell 3 is fixedly installed on the top of one side of the clamping platform 2, an axle frame 4 is arranged on the right end of the inner side of the shell 3, and a cylinder 5 is movably installed on the end of the axle frame 4; a first clamping strip 6 is movably installed on the top of the side of the base 1 away from the shell 3, a second clamping strip 7 is movably installed on the top of the side of the base 1 close to the shell 3, and linkage mechanisms 8 are arranged on both ends of the inner side of the shell 3, and the linkage mechanism 8 includes a gear 801, a rack 802 and a second guide rod 803; the second guide rods on both sides One end of 803 away from the housing 3 is fixedly connected to both sides of the first clamping strip 6, and the first guide rod 9 is fixedly installed at both ends of the middle part of the second clamping strip 7 close to the housing 3. The second clamping strip 7 is movably connected to the second guide rod 803. The output shaft end of the cylinder 5 is fixedly installed with a mounting bracket 11, and the mounting bracket 11 is fixedly connected to the back of the second clamping strip 7; the inner ends of the housing 3 are movably installed with gears 801 through rotating shafts, and racks 802 are arranged on both sides of the first guide rod 9 and the second guide rod 803 close to the gear 801, and the two racks 802 are meshed with the gear 801;

[0027] In this embodiment, during clamping, the cylinder 5 is started and pushes the mounting frame 11 forward. After the mounting frame 11 is pushed forward, it controls the second clamping strip 7 to move forward. When the second clamping strip 7 moves forward, it drives the first guide rod 9 to move synchronously. After the first guide rod 9 moves synchronously, it drives the rack 802 thereon to control the gear 801 to rotate. After the gear 801 rotates, it drives the rack 802 on one side of the second guide rod 803 to move backward. When the second guide rod 803 moves backward, it controls the first clamping strip 6 to move toward the direction of the second clamping strip 7 until the first clamping strip 6 and the second clamping strip 7 are clamped on both sides of the workpiece, thereby achieving the purpose of facilitating quick clamping.

[0028] like Figure 2 As shown, guide sleeves 10 are provided at both ends of the housing 3 close to the rack 802, and the first guide rod 9 and the second guide rod 803 are movably connected to the guide sleeves 10 at both ends respectively;

[0029] In this embodiment, when the first clamping strip 6 and the second clamping strip 7 move, the first guide rod 9 and the second guide rod 803 will slide along the inside of the guide sleeve 10 for guidance, and at the same time, the stability of the workpiece after clamping can be improved.

[0030] like Figure 1 and Figure 4 As shown, a movable groove 12 is provided in the middle of the same side of the first clamping strip 6 and the second clamping strip 7, a movable block 13 is movably installed inside the movable groove 12, springs 14 are fixedly installed on the inner walls of both sides of the movable groove 12, and side blocks 15 are provided on both sides of the movable block 13, and the side blocks 15 are fixedly connected to the other end of the spring 14;

[0031] In this embodiment, when the clamped workpiece has a circular structure, during the process of the first clamping strip 6 and the second clamping strip 7 clamping the workpiece, the movable block 13 will be retracted into the movable groove 12, and at the same time drive the side block 15 to compress the spring 14. When the first clamping strip 6 and the second clamping strip 7 release the workpiece, the compressed spring 14 will control the side block 15 to reset and pop out the movable block 13, so that workpieces of different shapes can be flexibly clamped.

[0032] like Figure 1 and Figure 2 As shown, a telescopic slot 16 is provided between the middle of the clamping platform 2 near the first clamping strip 6 and the second clamping strip 7, dampers 17 are provided at the four corners of the telescopic slot 16, and ejection plates 18 are provided at the output shaft ends of the four dampers 17;

[0033] In this embodiment, when placing a workpiece, the workpiece is pressed against the ejection plate 18 until the ejection plate 18 is received in the telescopic slot 16. When the processing is completed, the damper 17 controls the ejection plate 18 to reset and eject the workpiece.

[0034] Working principle: when clamping, the workpiece to be stamped is placed on the ejection plate 18, and then the cylinder 5 is started. After the cylinder 5 is started, the mounting frame 11 is pushed forward. After the mounting frame 11 is pushed forward, the second clamping bar 7 is controlled to move forward. When the second clamping bar 7 moves forward, it drives the first guide rod 9 to move synchronously. After the first guide rod 9 moves synchronously, it drives the rack 802 thereon to control the rotation of the gear 801. After the gear 801 rotates, it drives the rack 802 on one side of the second guide rod 803 to move backward. When the second guide rod 803 moves backward, it controls the first clamping bar 6 to move in the direction of the second clamping bar 7 until the first clamping bar 6 and the second clamping bar 7 are clamped on both sides of the workpiece; when the clamped workpiece is a circular structure, during the process of the first clamping bar 6 and the second clamping bar 7 clamping the workpiece, the movable block 13 will be retracted into the movable groove 12, and at the same time drive the side block 15 to compress the spring 14. When the first clamping bar 6 and the second clamping bar 7 release the workpiece, the compressed spring 14 will control the side block 15 to reset and pop out the movable block 13.

[0035] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
