Types of stamping dies include blanking dies, drawing dies, bending dies, flanging dies, curling dies, etc. They are widely used in various fields, including automobiles, electronics, and daily hardware. The materials used to make stamping dies include steel, cemented carbide, steel-bonded cemented carbide, zinc-based alloy, low-melting-point alloy, aluminum bronze, polymer materials, etc. Most of the materials used to make stamping dies are steel-based. When making stamping dies, process analysis should be carried out to determine the basic procedures based on the shape characteristics, dimensional accuracy, and surface quality requirements of the workpiece.

[0003] High-precision stamping dies are composed of fixed parts and movable parts. The fixed parts are fastened to the workbench of the press with pressure plates, bolts, etc., and the movable parts are generally fastened to the slide of the press. The stamping die will generate a lot of heat during the stamping process. In order to dissipate this heat, water circulation is usually used. When the stamping process is in progress, the pump body will be continuously started for water cooling circulation, resulting in the stamping process being unable to be synchronized with the heat dissipation process, resulting in a large amount of additional energy loss. Summary of the invention

[0005] To achieve the above purpose, the utility model provides the following technical solutions: a high-precision stamping die supporting continuous die stamping processing, comprising a base frame, a forming die seat and a stamping template,

[0006] A forming mold seat is arranged on the upper side of the base frame, a stamping template is arranged on the upper side of the forming mold seat, the top of the stamping template is connected to the bottom of the hydraulic cylinder, a water pump is installed at the bottom of the base frame, a water storage cavity is opened inside the base frame, the bottom of the water pump is connected to the bottom of the water storage cavity through a pumping pipe, and a water supply pipe is connected to the upper side of the water pump.

[0012] Compared with the prior art, the beneficial effect of the utility model is that the high-precision stamping die that supports continuous die stamping processing, after the displacement sensor receives the displacement signal, it will be processed by the corresponding signal processor and then start the water pump. When the stamping is completed, the hydraulic cylinder drives the stamping template and the plug-in rod to reset. At this time, the displacement detector no longer accepts extrusion, and the water pump stops working. This solves the problem that the high-precision stamping die will continuously start the pump body for water cooling circulation during the stamping process, which will result in a large amount of extra energy loss.

[0013] 1. The high-precision stamping die supporting continuous die stamping processing, in order to avoid energy loss, when the hydraulic cylinder drives the stamping template to move downward, the plug-in rods on both sides of the stamping template will move downward accordingly, and the stamping template will drive the plug-in rod to move downward while continuously plugging with the mounting rod until the displacement detector on the upper side of the mounting rod is abutted and pushed. After the displacement sensor receives the displacement signal, it will be processed by the corresponding signal processor and then start the water pump. When the stamping is completed, the hydraulic cylinder drives the stamping template and the plug-in rod to reset. At this time, the displacement detector is no longer squeezed, and the water pump stops working accordingly. The high-precision stamping die supporting continuous die stamping processing is provided with a displacement detector, which can trigger and start the water pump according to the signal of the displacement detector, thereby improving the follow-up performance of the high-precision stamping die and saving energy.

[0014] 2. The high-precision stamping die that supports continuous die stamping processing has a sealed cavity inside the base frame to improve the stability of the forming die seat during stamping. When the forming die seat is pushed downward by the stamping template, the connecting rods on both sides will drive the first sealing plug to compress the gas downward. The compression process will provide buffer protection for the descent of the forming die seat. When the gas in the sealed cavity is continuously compressed, it will push the second sealing plug to move upward. At this time, the water guide groove opened inside the second sealing plug will dock with the openings at the water supply pipe and the water supply pipe to open the water supply channel. After the stamping is completed, the air pressure inside the sealed cavity and the reset spring on the top of the second sealing plug will reset, close the water supply channel, and prevent water backflow. The high-precision stamping die that supports continuous die stamping processing is provided with a stabilizing mechanism to achieve stable downward movement and stable water supply of the forming die seat.

DETAILED DESCRIPTION

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-Figure 4 The utility model provides a technical solution: a high-precision stamping die supporting continuous die stamping processing, comprising a base frame 1, a forming die seat 2 and a stamping template 3,

[0023] A forming mold seat 2 is arranged on the upper side of the base frame 1, and a stamping template 3 is arranged on the upper side of the forming mold seat 2.

The bottom of the water pump 4 is connected to the bottom of the water storage chamber 401 through a water pumping pipe 402, and a water supply pipe 403 is connected to the upper side of the water pump 4.

[0024] Displacement detectors 5 are provided on both sides of the stamping template 3. The outer side of the displacement detector 5 is connected to the top of the mounting rod 501, and the outer side of the mounting rod 501 is plugged into the inside of the plug-in rod 502. The adjacent sides of the two plug-in rods 502 are installed with the stamping template 3. The bottom of the mounting rod 501 is connected to the forming mold seat 2. A water pipe 6 is installed inside the base frame 1. A water diversion groove 601 is opened at the bottom of the forming mold seat 2, and a circulating water groove 602 is opened inside the base frame 1.

[0025] In the specific implementation, in order to avoid energy loss, when the hydraulic cylinder 301 drives the stamping template 3 to move downward, the plug-in rods 502 on both sides of the stamping template 3 will move downward accordingly. While the stamping template 3 drives the plug-in rods 502 to move downward, it will continue to plug with the mounting rod 501 until the displacement detector 5 on the upper side of the mounting rod 501 is abutted and pushed. After the displacement sensor receives the displacement signal, it will be processed by the corresponding signal processor and then start the water pump 4. The water pump 4 transports water from the water storage chamber 401 in the base frame 1 through the water delivery pipe 403 to the water guide pipe 6 and the water diversion trough 601 through the water pumping pipe 402 at the bottom, and contacts with the forming mold pressing seat 2 for cooling. After the water level continues to rise in the base frame 1, the water flow at the top will enter the circulating water tank 602 and return to the water storage chamber 401 for storage.

[0026] When the stamping is completed, the hydraulic cylinder 301 drives the stamping template 3 and the connecting rod 502 to reset. At this time, the displacement detector 5 is no longer squeezed, and the water pump 4 stops working. The high-precision stamping die that supports continuous die stamping processing is provided with a displacement detector 5, which can trigger and start the water pump 4 according to the signal of the displacement detector 5, thereby improving the follow-up performance of the high-precision stamping die and saving energy.

[0028] In the specific implementation, in order to improve the stability of the forming mold seat 2 during stamping, a sealed cavity 703 is opened inside the base frame 1. When the forming mold seat 2 is pushed downward by the stamping template 3, the connecting rods 701 on both sides will drive the first sealing plug 702 to compress the gas downward. During the compression process, a buffer protection will be provided for the descent of the forming mold seat 2. When the gas in the sealed cavity 703 is continuously compressed, it will push the second sealing plug 704 to move upward. At this time, the water guide groove 705 opened inside the second sealing plug 704 will align with the openings of the water supply pipe 403 and the water supply pipe 6. Next, open the water supply channel. After the stamping is completed, when the stamping template 3 is reset, the forming mold seat 2 is driven to reset through the mounting rods 501 and the plug-in rods 502 on both sides. At this time, it is reset under the action of the internal air pressure of the sealing cavity 703 and the reset spring 707 on the top of the second sealing plug 704, and the water supply channel is closed to prevent water backflow. A through hole 706 is provided on the upper side of the chamber where the reset spring 707 is located to maintain the same air pressure as the outside world. The high-precision stamping die that supports continuous die stamping processing is provided with a stabilizing mechanism 7, which can realize the stable downward movement of the forming mold seat 2 and stable water supply.

[0029] To sum up, when using the high-precision stamping die that supports continuous die stamping processing, when the hydraulic cylinder 301 drives the stamping template 3 to move downward, the connecting rods 502 on both sides of the stamping template 3 will move downward accordingly, and the stamping template 3 will drive the connecting rods 502 to move downward while continuously connecting with the mounting rod 501 until the displacement detector 5 on the upper side of the mounting rod 501 is abutted and pushed. After receiving the displacement signal, the displacement sensor will start the water pump 4 after processing it through the corresponding signal processor. The water pump 402 at the bottom of the water pump 4 will return the water source inside the water storage chamber 401 through the water supply pipe 403, the water guide pipe 6, the water diversion trough 601 and the circulating water trough 602 back to the water storage chamber 401.
