TECHNICAL FIELD
[0001] The present application relates to the field of harp nail processing, in particular, to a harp nail forming die mechanism. BACKGROUND
[0002] In the prior art, the specific process steps of the harp nail in the forming process are as shown in the figure, which requires at least four die pressing steps from raw material to final product, and each die pressing step has at least different upper die or lower die, i.e. the head and tail of the harp nail need to be processed and formed respectively. Figure 1
[0003] Since the harp nail is small in size, batch die pressing is adopted to improve efficiency during each die pressing, i.e. multiple raw materials are processed simultaneously at each process step, but this method also has disadvantages. Since the dies are different at each process step, the workpiece needs to be loaded, clamped and unloaded when the process steps are converted. At present, this is done manually, which is low in efficiency and prone to misoperation, i.e. the head and tail of the workpiece are prone to be reversed when the worker places it on the die.
[0004] Therefore, those skilled in the art need to improve the forming die to overcome the above technical problems. CONTENT OF THE UTILITY MODEL
[0005] The main purpose of the present application is to provide a harp nail forming die mechanism which converts the workpiece between different stations in an automatic conveying manner, and the operator does not need to frequently load and unload during processing in different stations, greatly improving the efficiency and avoiding misoperation.

[0007] Optionally, the locking structure is a ring-shaped air bag, and a gas supply channel is formed on the workpiece carrying frame and communicates with the ring-shaped air bag.
[0008] Optionally, the air supply channel is connected with each annular air bag through a pressure divider.

[0010] Optionally, a limiting groove in the form of a ring is arranged in the perforation, and the annular air bag is fixedly arranged in the limiting groove.
[0011] Optionally, the annular air bag is adhesively fixed in the limiting groove.

[0013] Optionally, the moving unit is a chain conveyor or a synchronous belt conveyor.
[0014] Compared with the prior art, the Harake nail forming die mechanism has the beneficial effects that: the moving conveying assembly is adopted to sequentially convert the workpieces between the stations, the workpiece carrying frame is arranged to simultaneously carry multiple workpieces for batch processing, the locking structure is arranged in the perforation, the locking structure locks the workpiece in the perforation during the movement, therefore, the workpiece moves together with the workpiece carrying frame, when processing is needed, the locking structure is unlocked to release the workpiece from the constraint in the perforation, the head and the tail can be formed by using the forming die, and since the thickness of the workpiece carrying frame is much smaller than the length of the workpiece, the workpiece carrying frame is directly arranged between the forming dies during the forming, after the forming is completed, the workpiece is locked on the workpiece carrying frame by using the locking structure and then moves to the next station for processing by using the moving unit, which is not only high in efficiency, but also avoids misoperation.

[0025] In addition, the meaning of the term "a plurality of" should be two and more than two.
[0026] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.
[0027] like Figures 2-4 As shown, an automatic cleaning device for waste residue from pickling and phosphating tanks includes a mobile conveying assembly for conveying workpieces, and a first station 4, a second station 5, a third station 6, and a fourth station 7 arranged sequentially along the moving direction of the mobile conveying assembly. The mobile conveying assembly includes a workpiece support frame 1 and a moving unit for driving the workpiece support frame 1 to move. The workpiece support frame 1 has at least one through hole 2 for the workpiece to pass through. A locking structure is provided in the through hole 2. The locking structure has two working positions. When it is in the first working position, the locking structure is separated from the workpiece. When it is in the second working position, the locking structure surrounds the workpiece and clamps the workpiece in the through hole 2. The depth of the through hole 2 is less than one-third of the length of the workpiece.
[0028] The specific structure of the moving unit is not the focus of this application. Conventional conveyor frames in the prior art can be used, such as chain conveyor frames or synchronous belt conveyor frames. Their specific working principles will not be elaborated here.
[0029] Preferably, the locking structure is an annular airbag 3. The workpiece support frame 1 has an air supply channel, which is connected to the annular airbag 3. Locking is achieved by inflating and deflating the annular airbag 3. After the airbag is inflated, it expands and tightly surrounds the workpiece, with a large contact area. Thus, the workpiece is fixed in the perforation 2 by friction. When it is deflated, it separates from the surface of the workpiece. After the workpiece is freed from restraint, it can move freely in the perforation 2. Since the workpiece support frame 1 is located on the current forming mold when the air is deflated, the workpiece falls directly into the forming cavity of the forming mold through the perforation 2 after deflating. After forming is completed, the workpiece is locked in the perforation 2 by the annular airbag 3, and then the workpiece moves to the next station with the workpiece support frame 1.
[0030] To ensure the stability of the air pressure inside each annular airbag 3, the air supply channel is connected to each annular airbag 3 through a pressure divider valve.
[0031] To ensure sufficient friction to lock the workpiece in place, the thickness of the annular airbag 3 is greater than half the depth of the perforation 2.
[0032] For ease of processing, an annular limiting groove is provided inside the perforation 2, and the annular airbag 3 is fixedly disposed in the limiting groove. The annular airbag 3 is bonded and fixed in the limiting groove.
[0033] like Figure 2As shown, the first station 4, the second station 5, the third station 6 and the fourth station 7 each include an upper die holder, an upper die slidingly arranged on the upper die holder, a lower die holder, and a lower die slidingly arranged on the lower die holder. The upper die and the lower die each have a forming cavity, and are driven to slide by a driving mechanism.
[0034] The above only shows the preferred embodiments of the present application and is not intended to limit the present application. Various modifications and changes can be made by those skilled in the art to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
