[0025] In the embodiments of the present utility model, unless otherwise clearly specified and limited, the terms "mounted", "connected", "coupled", "fixed", etc. shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral body; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the internal communication of two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present utility model can be understood according to specific circumstances.

[0026] In some embodiments of the present utility model, such as Figure 1 - Figure 2As shown, a stainless steel deep drawing hardware mold is provided, including an upper die base 100, a lower die base 200 and a host computer. The upper die base 100 and the lower die base 200 are connected to each other. The upper die base 100 is provided with a plurality of connection holes 110. The lower die base 200 is provided with a plurality of dampers and a distance measurement component 210. The upper end of the damper is connected to the bottom of the upper die base 100. The distance measurement component 210 is arranged around the outer circle of the damper. The distance measurement component 210 faces the connection hole 110. A power supply socket is arranged on the outer side wall of the lower die base 200. After being connected in series with each other, each distance measurement component 210 is electrically connected to the power supply socket. The distance sensor 212 is electrically connected to the host computer. The distance measurement component 210 is used to measure the pressing-down distance of the upper die base 100 and transmit the distance information to the host computer.

[0027] During the process of the upper die base 100 pressing down on the lower die base 200, the distance measurement component 210 gradually enters the connection hole 110, and the distance measurement component 210 continuously obtains the distance information between its top end and the bottom of the connection hole 110. After the distance measurement component 210 transmits the distance information to the host computer, when the distance between the top of the measurement sensor and the bottom of the connection hole 110 is less than a preset distance value, the host computer issues an alarm or controls the upper die base 100 to stop pressing down on the lower die base 200. At this time, the stainless steel stretching process ends, and a stainless steel object with a predetermined depth is obtained. Compared with the traditional die stretching process, the present utility model no longer relies on the simple limit of the female die and the punching head for production, thus avoiding the disadvantage of low production accuracy. Different depths of stainless steel objects can also be produced by setting different distance values to control the pressing-down depth of the upper die.

[0028] During the pressing-down process, the damper increases the resistance suffered by the upper die during pressing down, so that the upper die presses down slowly, thus avoiding the situation that the upper die base 100 cannot be stopped in time due to communication delay.

[0029] In other embodiments of the present utility model, as Figure 1 - Figure 2 shown, the distance measurement component 210 includes a mounting post 211 and a distance sensor 212. The mounting post 211 is fixedly installed on the upper surface of the lower die base 200. The distance sensor 212 is installed at the top end of the mounting post 211. A wire hole for wires to pass through is provided at the lower end of the mounting post 211. After being connected in series through wires, each distance sensor 212 is electrically connected to the power supply socket. Specifically, the wires are arranged inside the lower die base 200.

[0030] During the downward pressing of the upper die holder 100, the connecting column gradually enters the connecting hole 110. Through the cooperation of the connecting column and the connecting hole 110, the upper die holder 100 and the lower die holder 200 are more easily positioned and aligned.

[0031] In some other embodiments of the present invention, the damper is a pneumatic cylinder. The rigid body of the pneumatic cylinder is disposed inside the lower die holder 200. The output shaft of the pneumatic cylinder extends out of the lower die holder 200 and is connected to the upper die holder 100. Specifically, during the downward pressing of the upper die holder 100, the pneumatic cylinder gradually releases pressure, so that the supporting force of its output shaft on the upper die holder 100 is less than the downward pressure of the upper die holder 100.

[0032] In some other embodiments of the present invention, the stainless steel deep drawing hardware die further includes an alarm component. The alarm component includes a buzzer (not shown in the figure), a power supply (not shown in the figure), a first connecting piece 300, a second connecting piece 400, and a third connecting piece 500 for forming a closed circuit. The first connecting piece 300 and the second connecting piece 400 are disposed on the upper surface of the lower die holder 200, and the first connecting piece 300 and the second connecting piece 400 are provided with disconnection parts. The third connecting piece 500 is disposed on the lower surface of the upper die holder 100, and the third connecting piece 500 is disposed directly above the disconnection part. When the upper die holder 100 is pressed downward, one end of the third connecting piece 500 is connected to the first connecting piece 300, and the other end of the third connecting piece 500 is connected to the second connecting piece 400, so that the buzzer, the power supply, the first connecting piece 300, the second connecting piece 400, and the third connecting piece 500 form a closed circuit. Specifically, when the third connecting piece 500 is connected to the first connecting piece 300 and the second connecting piece 400, that is, when the upper die holder 100 and the lower die holder 200 are closed, the buzzer emits a prompt sound due to being energized, reminding the producer to pay attention to whether the upper die holder 100 stops pressing downward in time.

[0033] In some other embodiments of the present invention, the buzzer, the power supply, the first connecting piece 300, the second connecting piece 400, and the third connecting piece 500 are connected by wires, and the wires are hidden inside the lower die holder 200.

[0034] In some other embodiments of the present invention, such as Figure 1 - Figure 2The stainless steel deep drawing hardware die shown also includes a buffer plate 600. Both the upper die holder 100 and the lower die holder 200 are fixedly connected to the buffer plate 600. A plurality of connecting grooves 610 are provided on the connecting surface of the buffer plate 600. A plurality of upper connecting notches are provided at the upper edge of the upper die holder 100. A plurality of lower connecting notches 220 are provided at the lower edge of the lower die holder 200. The buffer plate 600 can effectively protect the upper die holder 100 and the lower die holder 200 from being damaged due to huge pressure.

[0035] In some other embodiments of the present invention, as shown in Figure 3, the upper connecting notch and the lower connecting notch 220 are fixedly connected to the connecting groove 610 through bolts and gaskets, so that the upper die holder 100 and the lower die holder 200 are fixedly connected to the buffer plate 600.

[0036] In some other embodiments of the present invention, as Figure 3 The stainless steel deep drawing hardware die shown also includes a sliding connector 700. The sliding connector 700 includes an abutting member 710 and a slider 720. The slider 720 is connected to one end of the abutting member 710. The abutting member 710 is inserted into the upper connecting notch or the lower connecting notch 220. The slider 720 is slidably mounted in the connecting groove 610. By sliding the slider 720 in the connecting groove 610, the upper die holder 100 or the lower die holder 200 can slide on the buffer plate 600 without detaching from the buffer plate 600, so as to realize position adjustment. Specifically, in this embodiment, the slider 720 includes a sliding plate and a ball which are connected to each other. The sliding plate is connected to the abutting member 710. The ball is fixed on the sliding plate and is slidably arranged in the connecting groove 610. The sliding plate is arranged between the lower die holder 200 and the buffer plate 600 and plays a supporting role.

[0037] In some other embodiments of the present invention, the connecting grooves 610 on the buffer plate 600 are arranged at equal intervals.

[0038] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
