Description

Technical Field

[0001] The utility model relates to the technical field of die installation, in particular to a stamping die table for quick installation. Background Technique

[0002] Stamping is a forming processing method that applies external force to materials by a press and a die, so that plastic deformation or separation occurs, thereby obtaining workpieces with the required shapes and sizes.

[0003] Stamping dies are often installed and fixed using a machine base such as a punching press. The upper die of a stamping die is generally a punch. In fact, the machine base is generally universal. By replacing the punch of the stamping die, products of different specifications or types can be processed on the same punching press; or when a stamping die fails, it needs to be replaced and repaired. However, the existing stamping die heads are generally fixedly connected by a plurality of threaded bolts, and the disassembly and assembly are time-consuming. Content of the Utility Model

[0004] The purpose of the utility model is to provide a stamping die table for quick installation to overcome the above-mentioned defects in the prior art.

[0005] A stamping die table for quick installation according to the present utility model includes a first fixing table. A stamping cylinder is fixedly provided at the upper end of the first fixing table. A telescopic sliding rod extending downward through the first fixing table is power-connected to the lower end of the stamping cylinder. A second fixing table is fixedly connected to the telescopic end at the lower end of the telescopic sliding rod. A fixing head is installed at the lower end of the second fixing table. A positioning plate is provided at the outer end of the fixing head. Four convex platforms are fixedly provided on the second fixing table and are circumferentially and evenly distributed. A fixing rod is slidably provided on each convex platform. The lower ends of the four fixing rods are connected to the positioning plate. A spring is connected between the positioning plate and the convex platform and is located on the outer circumference of the fixing rod. An installation cavity is communicated between the second fixing table and the fixing head. The installation cavity is opened upward. A plug rod is inserted into the installation cavity. A handle is fixedly connected to the upper end of the plug rod. Two symmetrically arranged clamping cavities are opened on the second fixing table. A positioning rod is inserted into the clamping cavity. A through cavity is opened on the handle. The through cavity is symmetrically arranged with the key groove position of the clamping cavity in the left-right direction. A clamping key is fixedly provided on the positioning rod and is in clamping fit with the clamping cavity. A clamping plate is fixedly connected to the lower end of the plug rod. A clamping groove is opened in the fixing head. The clamping plate abuts against the side wall of the clamping groove. A cylindrical platform is fixedly provided on the installation cavity of the plug rod at the second fixing table. An installation plate is connected to the upper side wall of the installation cavity through a threaded fixing member. A torsion spring is connected between the installation plate and the cylindrical platform. A circumferentially surrounding and evenly distributed clamping groove is opened on the upper side wall of the clamping groove. A clamping key is fixedly provided at the upper end of the clamping plate. A friction pad is provided on the clamping key and abuts against the clamping groove wall of the clamping groove. A through groove is communicated at the clamping groove and extends upward through the fixing head and the second fixing table.

[0006] The beneficial effects of the present utility model are as follows:

[0007] By the abutment between the friction pad and the side wall of the clamping groove, the friction force is increased to prevent the plug rod from rotating and resetting after losing the support of the user due to the torsional spring force at the torsion spring, which is convenient for the user to take out the positioning rod for installation and disassembly work. It can realize the installation work of the handle and the positioning rod with one hand, and thus realize the installation and disassembly work of the handle and the positioning rod with both hands at the same time, improving the installation and disassembly efficiency of the fixing table and the fixing head. Through the sliding fit between the fixing head and the positioning plate, it is prevented from being eccentric during the installation of the fixing head, which is convenient for installation.

[0019] Embodiment 1:

[0020] Refer to Figures 1 - 7, A quickly installed stamping die table according to an embodiment of the present utility model includes a first fixed table 10. A stamping cylinder 11 is fixedly arranged at the upper end of the first fixed table 10. The lower end of the stamping cylinder 11 is power-connected with a telescopic slide rod 12 extending downward through the first fixed table 10. The lower end of the telescopic slide rod 12 is fixedly connected with a second fixed table 13. A fixed head 14 is installed at the lower end of the second fixed table 13. A positioning plate 15 is arranged at the outer end of the fixed head 14. Four convex platforms are fixedly arranged on the second fixed table 13 and are circumferentially and evenly distributed. A fixed rod is slidably arranged on each convex platform. The lower ends of the four fixed rods are connected with the positioning plate 15. A spring 16 is connected between the positioning plate 15 and the convex platform and is located on the outer periphery of the fixed rod. An installation cavity 27 is communicated between the second fixed table 13 and the fixed head 14. The installation cavity 27 is arranged with an upward opening. A plug rod 21 is inserted into the installation cavity 27. The upper end of the plug rod 21 is fixedly connected with a handle 17. Two symmetrically arranged clamping cavities 28 are opened on the second fixed table 13. A positioning rod 18 is inserted into the clamping cavity 28. A through cavity 26 is opened on the handle 17. The key groove positions of the through cavity 26 and the clamping cavity 28 are symmetrically arranged left and right. A clamping key is fixedly arranged on the positioning rod 18 and is in clamping fit with the clamping cavity 28. The lower end of the plug rod 21 is fixedly connected with a clamping plate 22. A clamping groove 24 is opened in the fixed head 14. The clamping plate 22 abuts against the side wall of the clamping groove 24. A cylindrical platform is fixedly arranged on the installation cavity 27 of the plug rod 21 at the position of the second fixed table 13. An installation plate 19 is connected to the upper side wall of the installation cavity 27 through a threaded fixing member. A torsion spring 20 is connected between the installation plate 19 and the cylindrical platform. A circumferentially surrounding and evenly distributed clamping groove is opened on the upper side wall of the clamping groove 24. A clamping key is fixedly arranged at the upper end of the clamping plate 22. A friction pad 23 is arranged on the clamping key and abuts against the clamping groove wall of the clamping groove 24. A through groove 25 is communicated at the position of the clamping groove 24. The through groove 25 extends upward through the fixed head 14 and the second fixed table 13;

[0021] Place the lower stamping die at the lower end position of the positioning plate 15. Select a corresponding fixed head 14 for installation according to the lower stamping die at the second fixed table 13. The fixed head 14 is inserted through the upper and lower through holes of the positioning plate 15, so that the upper end of the fixed head 14 passes through the clamping plate 22 through the opening of the through groove 25 and abuts against the lower end of the second fixed table 13. The user rotates the fixedly connected plug rod 21 through the handle 17. The plug rod 21 overcomes the torsional spring force at the torsion spring 20 to make the plug rod 21 rotate circumferentially. As Figure 4As shown, the card board 22 and the friction pad 23 rotate to the card slot 24 and abut against the side wall of the card slot 24, so that the through cavity 26 on the handle 17 and the positioning rod 18 on the second fixing table 13 are coaxially arranged. By the abutment between the friction pad 23 and the side wall of the card slot 24, the friction force is increased to prevent the insertion rod 21 from rotating and resetting after losing the support of the user due to the torsional spring force at the torsional spring 20. The user pushes down the positioning rod 18, and after the key on the positioning rod 18 passes through the through cavity 26, it rotates, so that the positioning rod 18 is inserted into the card cavity 28, and the key is engaged with the card cavity 28 in a matching manner. The handle 17 applies a force in the circumferential direction to the positioning rod 18 due to the torsional spring force at the torsional spring 20, and the circumferential rotation of the handle 17 is restricted by the positioning rod 18, thereby completing the installation work at the second fixing table 13 and the fixing head 14. By energizing the telescopic slide rod 12 to work, the second fixing table 13 is controlled to slide downward, so that the second fixing table 13 pushes the connected fixing head 14 to slide downward, and the stamping die head at the lower end of the fixing head 14 abuts against the lower die downward to complete the stamping work;

[0022] When disassembling, the user first pulls the positioning rod 18 to slide upward to disengage from the keyway fit, and then pushes the handle 17 to rotate circumferentially through the positioning rod 18, so that the card board 22 moves below the through slot 25. The user pulls the handle 17, so that the card board 22 slides upward through the through slot 25 into the second fixing table 13, and the card board 22 disengages from the cooperation with the fixing head 14 to complete the disassembly;

[0023] When replacing the handle 17 part, the user disassembles the threaded fixing parts at the mounting plate 19, and thus removes the mounting plate 19 and the handle 17 for replacement.

[0024] Those skilled in the art can clearly understand that various modifications can be made to the above embodiments without departing from the general spirit and concept of the present invention. All of them fall within the protection scope of the present invention. The protection scope of the present invention is subject to the claims attached to the present invention.
