[0002] The stamping die is a special process equipment for processing materials (metal or non-metal) into parts (or semi-finished products) in cold stamping processing, which is called a cold stamping die (commonly known as a cold stamping die). Stamping is a kind of pressure processing method that separates or plastically deforms materials at room temperature by using a die installed on a press to apply pressure to the materials, so as to obtain the required parts.

[0003] The punch cooling liquid is a liquid used in the stamping and die processing process, which cools the materials through water cooling or oil cooling, prevents the materials from overheating and deforming and damaging, and reduces the heat and friction in the processing process, prolongs the service life of the tool, and improves the precision and speed of the processing.

[0004] At present, before stamping, the manipulator first positions the plate at the preset position through the positioning device, then takes the plate through the manipulator, and sends the plate into the die. The plate placed on the die is sprayed with punch cooling liquid. After spraying, the plate is stamped by the stamping die.

[0005] In the above process, the positioning device only plays a positioning role, and the damage rate of the formed parts still does not meet the expectation. UTILITY MODEL CONTENT

DETAILED DESCRIPTION

[0024] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0025] In order to enable the person skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by the person skilled in the art without creative labor should belong to the protection scope of the present application.

[0026] It should be noted that the terms "first", "second" and the like in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, not necessarily to describe a specific order or sequence. It should be understood that the terms thus used can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product or device including a series of steps or units does not necessarily limit to those steps or units clearly listed, but can include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0027] It is to be understood that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms "comprises" and / or "comprising," when used in this specification, specify the presence of stated features, steps, operations, elements, components, and / or groups thereof, but do not preclude the presence or addition of one or more other features, steps, operations, elements, components, and / or groups thereof.

[0028] The inventor found that the reason for the part position to be easily deformed and damaged, and the service life of the tool to be affected, is that the punch cooling liquid cannot be uniformly sprayed on the material before stamping. In order to solve the above problems, as shown in Figure 1 The positioning device of the embodiment includes a base 10, an inclined plate 20, a stop structure 30, and a flow guide structure. The base 10 supports the inclined plate 20, the inclined plate 20 includes a positioning corner 21 with the lowest height and other corners with a height higher than the positioning corner 21, and the inclined plate 20 has a support surface for supporting the plate. The stop structure 30 extends along the direction of the two edges of the positioning corner 21. The flow guide structure is arranged on the stop structure 30 at the positioning corner 21.

[0029] By applying the technical solution of the embodiment, the plate is first placed on the positioning device for positioning before stamping. After positioning is completed, the plate can be uniformly sprayed with cooling liquid first, and then taken away from the positioning device for subsequent stamping after the spraying is completed. The cooling liquid remaining on the positioning device can flow out of the positioning device under the action of gravity through the flow guide structure at the positioning corner 21, preventing the cooling liquid from remaining on the positioning device and affecting subsequent positioning. Therefore, the above positioning device has the function of discharging cooling liquid in addition to the positioning function, which can reduce the damage rate of the parts while ensuring the accuracy of the positioning device, thereby improving the functionality of the positioning device.

[0030] It should be noted that in the embodiment, the robot takes the plate from the material stack, moves the plate above the inclined plate 20, and releases the plate. Under the action of gravity, the plate slides on the inclined plate 20 towards the positioning corner 21 until the plate is stopped by the stop structure 30. When the plate is stopped by the stop structure 30, the plate has reached the preset position.

[0031] Of course, in other embodiments not shown in the figure, the flow guide structure is arranged at the positioning corner 21 of the inclined plate 20. The above structure can also play a role in guiding the flow.

[0032] As shown in Figure 1As shown, in this embodiment, the stop structure 30 includes a first stop plate 31 and a second stop plate 32 extending along the two sides of the positioning angle 21, respectively. A notch 33 is formed between the first stop plate 31 and the second stop plate 32, and the notch 33 forms a flow guiding structure. The above structure is simple and easy to manufacture. Of course, in other embodiments not shown in the figure, the flow guiding structure can also be a flow guide pipe or other structures capable of guiding flow.

[0033] like Figure 1 As shown, in this embodiment, the positioning device further includes a liquid storage device 40. The inlet of the liquid storage device 40 is opposite to the guide structure. Specifically, after the coolant flows out from the guide structure, it can be introduced into the liquid storage device 40 for storage, avoiding coolant contamination of the ground. Preferably, in this embodiment, the guide structure is a notch 33, and the opening of the liquid storage device 40 is located directly below the notch 33. Under the action of gravity, the coolant falls from the notch 33 into the liquid storage device 40 below for storage.

[0034] In this embodiment, the positioning device further includes a filter (not shown in the figure), disposed between the flow guiding structure and the liquid storage device 40. This structure allows the coolant to be filtered before falling into the liquid storage device 40, enabling the coolant entering the liquid storage device 40 to be recycled.

[0035] Preferably, in this embodiment, the filtration device is a filter screen disposed at the liquid inlet of the liquid storage device 40. The above structure is simple and easy to implement. More preferably, the filter screen is detachably disposed at the liquid inlet of the liquid storage device 40, so that when the filter screen is clogged, the user can replace the old filter screen with a new one.

[0036] Preferably, in this embodiment, the positioning device further includes a delivery pipe and a delivery pump (not shown in the figure). The delivery pipe is connected to the outlet of the liquid storage device 40. The delivery pump is installed on the delivery pipe to pump coolant outward. The above structure allows the coolant in the liquid storage device 40 to be pumped back into the coolant spraying device, thereby achieving automatic coolant recovery.

[0037] like Figure 1 and Figure 2 As shown, in this embodiment, the positioning device further includes a detection sensor 50. The detection sensor 50 is disposed at the positioning angle 21 to detect whether a sheet metal is present at the positioning angle 21. If present, the detection sensor 50 sends a positioning signal to the robot arm. Upon receiving the positioning signal, the robot arm moves into position and picks up the positioned sheet metal. This structure improves the automation level of the positioning device and increases the overall stamping efficiency.

[0038] like Figure 1 and Figure 2As shown, in this embodiment, the detection sensing device 50 includes a sensor and a protective shell covering the sensor. This structure prevents the sensor from directly contacting the coolant, ensuring the sensor's lifespan.

[0039] like Figure 1 and Figure 2 As shown, in this embodiment, the stop structure 30 includes a first stop side plate 31 and a second stop side plate 32 extending along the two sides of the positioning angle 21, respectively. A notch 33 is formed between the first stop side plate 31 and the second stop side plate 32. The inclined plate 20 includes a plate body 22 and a plurality of anti-friction protrusions 23 disposed on the plate body 22. The upper surfaces of the plurality of anti-friction protrusions 23 form a support surface. The sensor includes a transmitting end 51 and a receiving end 52. The receiving end 52 is disposed at the notch 33 of the plate body 22, and is lower than the support surface. The transmitting end 51 is located directly above the receiving end 52. Specifically, when the plate moves above the inclined plate 20 and is released, the plate slides towards the positioning angle 21 on the inclined plate 20 under the action of gravity until the plate is stopped by the stop structure 30. When the plate is stopped by the stop structure 30, one corner of the plate moves to the notch 33 and is blocked between the transmitting end 51 and the receiving end 52. If the receiver 52 does not receive the signal transmitted by the transmitter 51 at this time, it proves that the plate has moved into place. The above structure is simple, and the sensor is arranged by making full use of the notch structure, making the positioning device more concise and reasonable.

[0040] like Figure 1 Figure 2 As shown, in this embodiment, the base 10 includes multiple telescopic legs. Specifically, the tilt angle of the tilting plate 20 can be adjusted by adjusting the telescopic length of the telescopic legs, making the equipment more flexible.
