Description

A metal stamping device Technical Field

[0001] This utility model relates to the field of metal processing technology, and more specifically to a metal stamping device. Background Technology

[0002] In existing metal stamping processes, traditional stamping equipment typically uses dies of fixed dimensions. These dies are designed and manufactured for metal sheets of specific specifications, and their size and shape cannot be changed after manufacturing. When stamping and folding of metal sheets of different lengths are required, the corresponding dies must be changed. Die changes require machine downtime, which directly leads to production line interruptions, reduces production efficiency, and is a very cumbersome and time-consuming process. Frequent die changes to produce products of different specifications make the production process complex and inefficient. Therefore, this application is proposed. Summary of the Invention

[0003] This utility model provides a metal stamping device, which has the advantage of being able to adjust the size of the mold according to the size of the stamping plate, and to stamp and fold metal plates of different lengths.

[0004] A metal stamping device includes a base, on which two adjustable-spaced stamping tables are symmetrically mounted. It also includes a crossbeam, on which two right-angled stamping heads are symmetrically slidably connected. The two right-angled stamping heads are located above the two stamping tables respectively. Two electric push rods II are symmetrically fixed between the crossbeam and the base. The distance between the two right-angled stamping heads can be adjusted synchronously with the two stamping tables.

[0005] Two symmetrical sliding grooves are provided on the base, and ear plates are fixedly connected to the lower ends of the two stamping tables. The two ear plates are slidably connected in the two sliding grooves respectively.

[0006] Two fixed seats are symmetrically fixed to the base, and a bidirectional screw is rotatably connected between the two fixed seats. A motor that drives the bidirectional screw to rotate is fixed to one of the fixed seats.

[0007] Two vertical rods are symmetrically fixed to each of the two stamping platforms, and the two right-angle stamping heads are slidably connected to the two vertical rods on the corresponding stamping platforms.

[0017] In the figure: base 101; slide 102; fixed seat 103; double screw 104; motor 105; electric push rod I 106; push plate 107; stamping table 201; ear plate 202; vertical rod 203; right angle stamping head 204; crossbeam 205; connecting rod 206; electric push rod II 207. Detailed Implementation

[0018] Referring to Figures 1 to 7, schematic diagrams are shown of embodiments of folding metal plates of different lengths according to the present invention;

[0019] A metal stamping device includes a base 101, on which two adjustable-spaced stamping tables 201 are symmetrically mounted. It also includes a crossbeam 205, on which two right-angle stamping heads 204 are symmetrically slidably connected. The two right-angle stamping heads 204 are respectively located above the two stamping tables 201. Two electric push rods II 207 are symmetrically fixed between the crossbeam 205 and the base 101. The distance between the two right-angle stamping heads 204 can be adjusted synchronously with the two stamping tables 201. Support legs are fixedly connected to the four corners of the base 101 for support.

[0020] The metal sheet to be stamped is placed on two stamping tables 201, with the metal sheet located between the stamping tables 201 and the right-angle stamping heads 204. When the telescopic ends of the two electric push rods II 207 retract instantaneously, they drive the two right-angle stamping heads 204 on the crossbeam 205 to move downward instantaneously. The right-angled side of the right-angle stamping head 204 cooperates with the right-angled side on the outside of the stamping table 201 to complete the mold closing, thereby achieving the edge folding treatment of both sides of the metal sheet.

[0021] There is a certain distance between the inner wall of the vertical plate on the right-angle punch head 204 and the outer end face of the punching table 201. This distance is equal to the thickness of the metal plate to be punched. Thus, when the right-angle punch head 204 and the punching table 201 are closed, the edge of the metal plate with its own thickness can be bent downward to form a 90-degree angle.

[0022] The distance between the two stamping tables 201 is adjustable, allowing metal plates of different lengths to be placed on the two stamping tables 201 for edge bending. This enables stamping and edge bending of metal plates of different lengths without the need to customize special molds for each size of metal plate, greatly improving production flexibility.

[0023] The spacing between the two right-angle punch heads 204 can be adjusted synchronously with the two punching tables 201 without the need for secondary adjustment. This eliminates the need for downtime to disassemble, install, and debug the molds, thus reducing the time required for mold replacement and debugging, making the production process more continuous and efficient.

[0024] The inner end faces of the right-angle punch head 204 and the punching table 201 connected thereto are coplanar; thus, during punching, the horizontal plate on the right-angle punch head 204 contacts and cooperates with the top surface of the punching table 201, thereby achieving the effect of pressing and solidifying the metal plate and improving the stability of the metal plate during punching.

[0025] Referring to Figures 2 to 4, schematic diagrams are shown of an embodiment of adjusting the distance between the two stamping tables 201 according to the present invention;

[0026] Two sliding grooves 102 are symmetrically opened on the base 101, and ear plates 202 are welded to the lower ends of the two stamping tables 201 respectively. The two ear plates 202 are slidably connected in the two sliding grooves 102 respectively.

[0027] Two fixed seats 103 are symmetrically fixed to the base 101 by screws. A bidirectional screw 104 is rotatably connected between the two fixed seats 103 by a bearing. A motor 105 is fixed to one of the fixed seats 103 by a motor frame and screws. The output shaft of the motor 105 is connected to the bidirectional screw 104 by a coupling.

[0028] The motor 105 starts and drives the bidirectional screw 104 to rotate. The threads on both sides of the bidirectional screw 104 turn in opposite directions, which in turn drives the two stamping tables 201 to move closer or further apart through the two ear plates 202, thereby changing the distance between the two stamping tables 201. Since the bidirectional screw 104 has the characteristic of thread self-locking, the distance between the two stamping tables 201 can be fixed after adjustment. Therefore, the two stamping tables 201 are suitable for placing metal plates of different lengths for stamping and folding.

[0029] Furthermore, transverse grooves may be provided on both end faces of the slide groove 102, and a convex ridge that matches the groove is formed on the ear plate 202, thereby preventing the ear plate 202 from shaking when the bidirectional screw 104 drives the ear plate 202 to move.

[0030] Referring to Figures 4 and 6, a schematic diagram of an embodiment of the present invention in which the stamping table 201 moves synchronously with the right-angle stamping head 204 is shown;

[0031] Two vertical rods 203 are symmetrically welded on each of the two stamping tables 201. Two right-angle punch heads 204 are provided with square holes corresponding to the vertical rods 203. The right-angle punch heads 204 are slidably connected to the vertical rods 203 on the corresponding stamping tables 201 through the square holes.

[0032] When the distance between the two stamping tables 201 changes, the two stamping tables 201 drive the two right-angle stamping heads 204 to move synchronously via their two vertical rods 203. This achieves synchronous adjustment of the distance between the two stamping tables 201 and the two right-angle stamping heads 204, eliminating the need to adjust the position of the two right-angle stamping heads 204 relative to the two stamping tables 201 separately and avoiding the possibility of errors caused by secondary adjustment. At the same time, the two right-angle stamping heads 204 can slide on the crossbeam 205, thus not interfering with the crossbeam 205 driving the two right-angle stamping heads 204, whose distance has changed, to perform the downward stamping and mold closing operation.

[0033] Referring to Figures 2 and 7, schematic diagrams are shown of an embodiment of the present invention for avoiding interference with the insertion and removal of the metal plate;

[0034] Both ends of the crossbeam 205 are fixedly connected to connecting rods 206, and the two connecting rods 206 are respectively fixedly connected to the upper ends of the two electric push rods II 207; the two electric push rods II 207 are located at the rear side of the base 101.

[0035] The two connecting rods 206 extend to the rear side of the base 101, thereby positioning the two electric push rods II 207 at the rear side of the base 101, making room on the left and right sides of the base 101, and preventing the position of the two connecting rods 206 from interfering with the insertion and removal of the metal plate.

[0036] Referring to Figure 2, a schematic diagram of an embodiment of the metal plate with easily removable folded edges according to the present invention is shown;

[0037] It also includes a push plate 107, with two electric push rods I 106 symmetrically fixed between the push plate 107 and the base 101; the push plate 107 is located between two stamping tables 201.

[0038] After stamping is completed, the two right-angle stamping heads 204 move upward to reset, and control the extension ends of the two electric push rods I 106 to extend and drive the push plate 107 to move upward. The push plate 107 pushes the stamped metal plate upward, thereby causing the folded metal plate to separate from the two stamping tables 201, making it easy to remove the metal plate.

[0039] Both ends of the electric push rod I 106 and the electric push rod II 207 are welded with flanges. The electric push rod I 106 is fixedly connected to the base 101 and the push plate 107 by the flange and screws. The electric push rod II 207 is fixedly connected to the base 101 and the connecting rod 206 by the flange and screws.

[0040] The electric linear actuator I106 and electric linear actuator II207 are available in model JS-TGZ-U2, and other applicable models in the prior art can also be used.

[0041] Motor 105 can be a servo motor.
