Description

Technical Field

[0001] This utility model relates to the field of stamping technology, and in particular, to a material receiving mechanism and production system for a die stamping equipment. Background Technology

[0002] Stamping equipment, also known as press, stamping machine, oil press or hydraulic press, is a special equipment that uses a hydraulic system to drive a mold to apply pressure to metal materials to achieve plastic forming. It is mainly used in automobile manufacturing, home appliances, electronics and aerospace fields for processes such as steel plate forming, head manufacturing and container pressing.

[0003] In the case where the die driven by the stamping equipment is a die cavity (i.e., die stamping equipment), after stamping is completed, the workpiece is located in the die cavity of the upper die base and moves upward with the upper die base. It is necessary to set up a cylinder or air blowing structure to make the workpiece detach from the die cavity of the upper die base. After detachment, the workpiece falls onto the lower die base, and another cylinder or air blowing structure is set up to push the workpiece out from the lower die base.

[0004] This approach has the following problems:

[0005] 1. It requires cylinders or air blowing equipment to achieve material removal and ejection, which is costly.

[0006] 2. During stripping, if the distance between the upper and lower die bases is large, the falling workpiece is prone to deformation, affecting production quality.

[0007] 3. The descent of the upper mold base can only be carried out after the material has been stripped and ejected, resulting in low production efficiency. Summary of the Invention

[0008] To overcome the shortcomings of existing technologies, this utility model provides a material receiving mechanism and production system for a die stamping equipment. This addresses the problems of existing die stamping equipment requiring cylinders or air-blowing equipment for material removal and ejection, resulting in high costs; during material removal, if the distance between the upper and lower die holders is large, the falling workpiece is prone to deformation, affecting production quality; and the lowering of the upper die holder can only occur after material removal and ejection, leading to low production efficiency.

Detailed Implementation

[0058] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this utility model will be described in detail below with reference to the accompanying drawings and embodiments. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments of this application, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0059] Reference Figure 1 , Figure 2 and Figure 3 as well as Figure 4 This utility model embodiment provides a material receiving mechanism for a die 9 stamping equipment, including: a transmission structure and a material receiving box 5;

[0060] The transmission structure includes a first connecting rod 3 and a second connecting rod 4;

[0061] The first link 3 and the second link 4 are hinged; as a preferred implementation of this application, the transmission structure further includes a third link 6, a fourth link 7, and a fixed rod 8;

[0062] The receiving box 5 is fixedly connected to one end of the fixing rod 8;

[0063] The other end of the first link 3 is hinged to one end of the fourth link 7;

[0064] The other end of the second link 4 is hinged to one end of the third link 6;

[0065] The other end of the third link 6, the other end of the fourth link 7, and the other end of the fixed rod 8 are hinged together.

[0066] The fixing rod 8 has a sliding hole;

[0067] The hinge joint between the first connecting rod 3 and the second connecting rod 4 is located inside the sliding hole;

[0068] When the upper mold base 1 moves, the hinge joint of the first connecting rod 3 and the second connecting rod 4 moves within the sliding hole.

[0069] One end of the first connecting rod 3 is hinged to the upper die holder 1 of the stamping equipment; one end of the second connecting rod 4 is hinged to the lower die holder 2 of the stamping equipment.

[0070] like Figure 5 As shown, when the upper mold base 1 rises, the material receiving box 5 is moved to below the cavity mold 9 of the upper mold base 1 through the transmission structure;

[0071] like Figure 6 As shown, when the upper mold base 1 descends, the transmission structure drives the receiving box 5 to move out from below the cavity mold 9 of the upper mold base 1.

[0072] It also includes a stripping device 10 for removing the workpiece from the upper mold base 1.

[0073] The workpiece inside die 9 can be stripped using a conventional stripping method. Alternatively, the following device can be used for stripping:

[0074] The unloading device 10 includes an unloading unit and a limiting unit;

[0075] The stripping unit is used to knock the workpiece out of the die 9 of the upper die holder 1;

[0076] The limiting unit is used to limit the rising height of the upper mold base 1;

[0077] When the upper mold base 1 rises to the height defined by the limiting unit, the receiving box 5 is located below the die cavity 9, and the stripping unit knocks the workpiece out of the die cavity 9 of the upper mold base 1.

[0078] The unloading unit includes an unloading punch 101 and a push rod;

[0079] The top rod is connected to the stripping rod 101;

[0080] The stripping rod 101 is disposed on the upper mold base 1, and the ejector rod is located directly above the cavity mold 9; the stripping rod 101 is connected to the limiting unit;

[0081] When the upper mold base 1 rises to the height defined by the limiting unit, the stripper rod 101 provides a downward force to the ejector rod, causing the ejector rod to knock the workpiece out of the die 9. The die 9 has openings at both the top and bottom, with the ejector rod located at the opening above the die 9. The stripper rod 101 provides a downward force to the ejector rod, thus pushing the workpiece out of the die 9.

[0082] The limiting unit includes: a first limiting rod 102 and a second limiting rod 103;

[0083] One end of the first limiting rod 102 is connected to one end of the stripping rod 101;

[0084] The other end of the first limiting rod 102 is provided with a first limiting block 104;

[0085] One end of the second limiting rod 103 is connected to the lower mold base 2;

[0086] The other end of the second limiting rod 103 is provided with a second limiting block 105;

[0087] The first limiting block 104 is located below the second limiting block 105;

[0088] The first limiting rod 102 moves with the upper mold base 1, and the second limiting block 105 is on the path of the first limiting block 104 moving upward. When the upper mold base 1 rises to the height defined by the limiting unit, the first limiting block 104 and the second limiting block 105 come into contact. The working process of the limiting unit can be referred to... Figure 7 and Figure 8 .

[0089] In one embodiment, a limiting unit is provided at each end of the stripper rod 101. This arrangement on both sides provides a more balanced distribution. Alternatively, it can be provided on only one side, with the stripper rod fixed to a certain position on the upper mold base 1 on the other side.

[0090] In addition, in order to prevent the operation of the stripping device 10 and the transmission structure from interfering with each other, when the transmission structure is located on the left or right side of the upper mold base 1, the limiting unit is located on the front and rear sides of the upper mold base 1.

[0091] The receiving mechanism provided in this embodiment includes a transmission structure and a receiving box. The transmission structure includes a first connecting rod and a second connecting rod, which are hinged together. One end of the first connecting rod is hinged to the upper die base of the stamping equipment; one end of the second connecting rod is hinged to the lower die base of the stamping equipment. When the upper die base rises, the receiving box moves to below the die cavity of the upper die base via the transmission structure. When the upper die base descends, the receiving box moves out from below the die cavity of the upper die base via the transmission structure. In this way, when the stamping is completed and the upper die base rises, the receiving box can catch the workpiece knocked off the die cavity of the upper die base by the stripping device. The receiving box moves through the upper die base and the transmission structure, eliminating the need for additional cylinders or motors, greatly reducing costs. Furthermore, the receiving box catches the workpiece when the upper die base rises and moves out when it descends, making operation simple and efficient.

[0092] To more clearly illustrate the technical solution of this application, the following will use... Figure 1 The structure shown is described in detail:

[0093] The main components of the receiving mechanism are:

[0094] Material receiving box, first connecting rod, second connecting rod, third connecting rod, fourth connecting rod, fixing rod, material ejection rod, top rod, first limiting rod, second limiting rod, first limiting block and second limiting block.

[0095] The receiving device consists of a receiving box, a first connecting rod, a second connecting rod, a third connecting rod, a fourth connecting rod, a fixing rod, and several washers, screws, and other accessories. The unloading device consists of a stripping rod, a push rod, a first limiting rod, a second limiting rod, a first limiting block, a second limiting block, screws, springs, and equal-height sleeves, and other standard parts.

[0096] The following is combined with Figure 5 , Figure 6 , Figure 7 and Figure 8 Describe the specific work process:

[0097] like Figure 8 As shown, when the mold opens, it drives the limit rods fixed on the upper and lower mold bases to move. When the limit blocks at both ends contact, they drive the ejector rod, which in turn drives the ejector pin to knock the workpiece down. Figure 5 As shown, when the mold opens, it drives the first, second, third, and fourth connecting rods and the fixed rod connected to the mold base to move. During this process, the receiving box is fed into the mold to catch the workpiece knocked off by the stripping device. When the mold closes, it drives the first, second, third, and fourth connecting rods and the fixed rod to move, thereby moving the receiving box backward, exiting the mold, and sending the workpiece to the packing box. This cycle repeats continuously.

[0098] The travel of the receiving box is controlled by the mold opening stroke and the length of the transmission structure. A longer mold opening stroke results in a longer connecting rod within the transmission structure, and thus a longer travel of the receiving box. Conversely, a shorter mold opening stroke results in a shorter connecting rod within the transmission structure, and thus a shorter travel of the receiving box. A certain angle exists between the receiving box and the transmission structure to facilitate catching the product and prevent the workpiece from detaching from the receiving box.

[0099] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such deductions or substitutions should be considered within the scope of protection of the present invention.

[0100] The material receiving mechanism provided in this application involves attaching the product to the cavity of the upper mold base during mold ejection, and then having the product knocked off by the ejector device during mold opening. The material receiving device is then fed into the mold during mold opening to catch the falling product, and then fed out of the mold during mold closing. This cycle repeats, changing the mold ejection method and the molding method of some products, simplifying the mold structure, and improving production efficiency and yield.

Furthermore, the receiving box receives the workpiece when the upper die base rises and moves out when it descends, making the operation simple and efficient.
