Description

Technical Field

[0001] The utility model belongs to the technical field of hardware processing, in particular to a stamping die for hardware processing. Background Art

[0002] Stamping dies for metal processing play a key role in modern manufacturing. These dies apply high pressure to cut, form, or press sheet metal into custom shapes. They are widely used in industries such as automotive, electronics, home appliances, and building materials. With the continuous advancement of technology and changes in market demand, stamping dies are constantly innovating. Modern stamping dies utilize high-strength materials and advanced coating technologies to improve durability and production efficiency. The application of intelligent and automated technologies enables real-time monitoring and remote control of dies, thereby improving production stability and efficiency.

[0003] After searching, the existing patent (Announcement No.: CN219648475U) discloses a stamping die for hardware processing, which includes: a base, two vertical rods are fixedly connected to the upper end of the base at intervals, support plates are installed on the side walls of the two vertical rods, two positioning rods are fixedly connected to the lower end of the support plate at intervals, a die table is installed in the middle of the upper end of the base, positioning holes are provided at both ends of the die table, limiting grooves are provided on both sides of the two positioning holes, second springs are installed at the bottom of the two positioning holes, pads are fixedly connected to the upper ends of the two second springs, a die groove is provided in the middle of the die table, mounting grooves are provided on both sides of the die groove, second slide rods are fixedly connected to the inside of the two mounting grooves, and second sliders are slidably connected to the outside of the two second slide rods. Through the above structure, the positioning rods and the positioning grooves are matched, so that the stamping block can accurately stamp the die to avoid misalignment.

[0004] However, in the actual use of the above solution, stamping dies for metal parts processing generally require cooling during use. This is because during the stamping process, the die contacts the metal sheet and applies high pressure, which generates a large amount of frictional heat and deformation heat. If the die remains at high temperature for a long time without cooling, the high temperature may cause die deformation or thermal stress, which in turn affects the dimensional accuracy and surface quality of the stamped part.

[0005] To this end, the utility model provides a stamping die for processing hardware. Utility Model Content

[0006] In order to make up for the deficiencies of the prior art and solve the problem that high temperature may cause mold deformation or thermal stress, thereby affecting the dimensional accuracy and surface quality of stamped parts, the utility model proposes a stamping die for hardware processing.

[0007] The cam is fixedly provided with a first end in front of the base, and a second end in front of the base is fixedly provided with a second end in front of the base, and a water channel is provided on the inner side of the second base, and a water outlet is provided on the inner side of the second base.

[0008] Through the above technical solution, cold water is transported through the water inlet pipe and transported into the water trough through the connecting rod and the water inlet to cool the bottom mold. At the same time, the heated cooling water is transported out through the water outlet and the water outlet pipe, so that the bottom mold can be cooled quickly. At the same time, the second base and the bottom mold are driven to move left and right by the sliding assembly, so that the second base can be cooled while the metal inside the other second base is stamped, thereby speeding up production efficiency.

[0009] Furthermore, the sliding assembly includes a first gear, a front-to-rear fixed frame fixedly connected to the inner side of the top end of the first base, a motor fixedly connected to the upper right outer end of the fixed frame, an output end of the motor fixedly connected to the first gear, a second gear meshed with the bottom end of the first gear, a threaded rod fixedly connected to the inner side of the second gear, a threaded slide evenly distributed on the outer side of the middle end of the threaded rod, a slider evenly distributed on the outer side of the threaded slide, the slider is clamped and connected to the fixed frame, a support frame is fixedly connected to the middle side of the bottom end of the threaded slide, and the support frame is clamped and connected to the second base;

[0010] Through the above technical solution, the motor utilizes the first gear, the second gear and the threaded rod to drive the threaded slide, the support frame and the slider to move left and right, thereby driving the second base to move synchronously.

[0011] Furthermore, a support plate is fixedly connected to the bottom of the middle end of the rear side of the first base, and the top end of the rear side of the support plate is fixedly connected to the left and right limiting seats opposite to each other, the rear side of the top end of the limiting seat is rotatably connected to the rotating frame, the inner side of the top end of the rotating frame is rotatably connected to the connecting handle, the front end of the limiting seat is rotatably connected to the transmission frame, the front end of the transmission frame is rotatably connected to the locking rod, the locking rod is slidably connected to the limiting seat, a third spring is provided on the outer side of the middle end of the locking rod, and the locking rod is locked and connected to the second base;

[0012] Through the above technical solution, by pulling the connecting handle backward and utilizing the rotating frame to drive the transmission frame and the locking rod to move backward at the same time, the third spring is stretched by the locking rod to cancel the locking of the second base, so that the second base can move freely, thereby increasing the stability of the device.

[0013] Furthermore, the stamping assembly includes a first spring, a first slide rod facing each other is slidably connected to the inner side of the middle end of the first base, a first spring is provided on the outer side of the middle end of the first slide rod, and a top die is fixedly connected to the top end of the first slide rod;

[0014] Through the above technical solution, the top mold is pushed upward by the first spring with the top of the first base as the stress point.

[0015] Furthermore, the total length of the first base is equal to the sum of the lengths of the three second bases;

[0016] Through the above technical solution, by setting the total length of the first base to be equal to the sum of the lengths of the three second bases, the moving distance of the second bases can be controlled when the two second bases move.

[0017] Furthermore, a sliding layer is provided between the first base and the second base;

[0018] Through the above technical solution, the friction between the first base and the second base can be reduced by the sliding layer.

[0019] The beneficial effects of the utility model are as follows:

[0020] 1. The utility model discloses a stamping die for hardware processing. Cold water is delivered through a water inlet pipe and then into a water trough via a connecting rod and a water inlet to cool the bottom die. Simultaneously, the heated cooling water is delivered through a water outlet and an outlet pipe, thereby rapidly cooling the bottom die. This rapid cooling effectively reduces heat accumulation during the stamping process, thereby slowing aging and wear of the die material. Operating the die within an appropriate temperature range helps maintain the stability of its structure and hardness, thereby extending the die's service life.

[0021] 2. The utility model describes a stamping die for hardware processing, which drives the two second bases to move left and right at the same time through a sliding assembly. At the same time, the retaining ring is squeezed when the second base moves left and right, driving the second sliding rod and the connecting rod to move synchronously, so that the water outlet, water inlet and water outlet pipe and water inlet pipe can be connected to achieve interconnection, thereby realizing the function of automatic water flow, thereby achieving the purpose of saving water.
