Hardware stamping die convenient to discharge

Abstract

The hardware stamping die comprises a base, a frame is fixedly installed at the top of the base, a hydraulic cylinder is fixedly installed in the middle of the top end of the frame, and the telescopic end of the hydraulic cylinder extends into an inner cavity of the frame and is fixedly connected with a lifting plate. And an upper module is fixedly mounted in the middle of the bottom end of the lifting plate. By arranging the push-pull assembly, when punching is completed, the lifting plate drives the upper die block to move upwards, the vertical plate can be driven to move upwards, due to the fact that the bottom of the through hole is inclined, along with movement of the vertical plate, the inner wall of the through hole can extrude the outer surface of the cylindrical block, and therefore the two cylindrical blocks can pull the two lower die blocks to move oppositely. According to the hardware blanking die, the two lower die blocks are arranged, so that the situation that stamped hardware is clamped in a groove between the two lower die blocks and is difficult to take out can be avoided, blanking of the hardware can be achieved without using tools, the working efficiency is improved, and the hardware blanking die has the advantage that blanking of the stamped hardware is facilitated.

Description

Technical Field

[0001] The utility model belongs to the technical field of stamping equipment, and in particular relates to a hardware stamping die which is convenient for blanking. Background Art

[0002] Molds are various molds and tools used in industrial production to obtain the desired products by injection molding, blow molding, extrusion, die casting or forging, smelting, stamping and other methods. In short, molds are tools used to make molded objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the object by changing the physical state of the molded material. At present, when processing hardware, staff often use stamping dies to achieve changes in the shape of the hardware.

[0003] However, there are some problems with the prior art: although the existing stamping dies can perform stamping processing on hardware, after the stamping is completed, the hardware is often stuck inside the groove of the stamping die, so that the staff usually need to use tools to pry the hardware out. This method of cutting is not only time-consuming and labor-intensive, but also easily causes the hardware to deform and be damaged during the prying process. Therefore, we propose a hardware stamping die that is easy to cut. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of the utility model is to provide a hardware stamping die that is convenient for cutting materials. By setting a push-pull component, the position of the lower module can be adjusted to facilitate the removal of hardware.

[0005] The utility model is implemented as follows: a hardware stamping die that is convenient for blanking comprises a base, a frame is fixedly installed on the top of the base, a hydraulic cylinder is fixedly installed in the middle of the top of the frame, the telescopic end of the hydraulic cylinder extends to the inner cavity of the frame and is fixedly connected to a lifting plate, an upper module is fixedly installed in the middle of the bottom end of the lifting plate, a block is fixedly installed in the middle of the top of the base, lower modules are movably installed on both sides of the top of the block, and the lower module is connected to the lifting plate by a push-pull assembly.

[0006] Optionally, a slide groove located below the lower module is provided on the top of the block, and a sliding block located inside the slide groove is fixedly connected to the bottom end of the lower module.

[0007] Optionally, the push-pull assembly includes two vertical plates, the two vertical plates are fixedly connected to two sides of the bottom of the lifting plate, and a through hole is opened on the vertical plate. The bottom of the through hole is inclined, and a connecting rod is fixedly connected to one side of the lower module close to the vertical plate, and a cylindrical block located inside the through hole is fixedly connected to the connecting rod.

[0008] Optionally, an inner groove is opened in the middle of the front side of the block, square holes communicating with the inner groove are opened on both sides of the top of the block, folding plates are arranged on both sides of the inner wall of the inner groove, the other end of the folding plate passes through the square hole and is fixedly connected with a clamping plate, and the folding plate is connected to the block through a driving mechanism.

[0009] Optionally, the driving mechanism includes a driving motor, which is fixedly installed in the middle of the front side of the block. The output shaft of the driving motor is fixedly sleeved with a bidirectional lead screw located inside the inner groove, and the two folding plates are respectively threadedly sleeved on both sides of the outer surface of the bidirectional lead screw.

[0010] Optionally, guide rods are fixedly mounted on both sides of the top of the lifting plate, and the tops of the guide rods extend to above the frame.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The utility model sets a push-pull assembly. When the lifting plate drives the upper module to move upward after the stamping is completed, it will drive the vertical plate to move upward. Since the bottom of the through hole is inclined, as the vertical plate moves, the inner wall of the through hole will squeeze the outer surface of the cylindrical block, so that the two cylindrical blocks can pull the two lower modules to move back to each other, thereby avoiding the situation where the stamped hardware is stuck in the groove between the two lower modules and is difficult to remove. In addition, the hardware can be unloaded without using tools, thereby improving work efficiency.

[0013] 2. The utility model is provided with a driving motor, a bidirectional screw, a folding plate and a clamping plate. After the staff places the hardware raw materials on the top of the lower module, they can start the driving motor to rotate the bidirectional screw, so that the two folding plates can drive the two clamping plates to move toward each other, and then the hardware raw materials can be clamped and straightened to avoid the hardware being placed crookedly, thereby improving the processing quality.

DETAILED DESCRIPTION

[0021] In order to further understand the content, features and effects of the utility model, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0022] like Figures 1 to 5 As shown, an embodiment of the utility model provides a hardware stamping die that is convenient for blanking, including a base 1, a frame 2 is fixedly installed on the top of the base 1, a hydraulic cylinder 3 is fixedly installed in the middle of the top of the frame 2, the telescopic end of the hydraulic cylinder 3 extends to the inner cavity of the frame 2 and is fixedly connected to a lifting plate 4, an upper module 5 is fixedly installed in the middle of the bottom end of the lifting plate 4, a block 6 is fixedly installed in the middle of the top of the base 1, lower modules 7 are movably installed on both sides of the top of the block 6, and the lower module 7 is connected to the lifting plate 4 by a push-pull assembly.

[0023] A slide groove 8 located below the lower module 7 is formed on the top of the block 6 , and a slider 9 located inside the slide groove 8 is fixedly connected to the bottom end of the lower module 7 .

[0024] The design of the slider 9 can limit the lower module 7 so that the lower module 7 can only slide on the surface of the block 6 .

[0025] The push-pull assembly includes two vertical plates 10, which are fixedly connected to the two sides of the bottom of the lifting plate 4 respectively. A through hole 11 is opened on the vertical plate 10, and the bottom of the through hole 11 is inclined. A connecting rod 12 is fixedly connected to the side of the lower module 7 close to the vertical plate 10, and a cylindrical block 13 located inside the through hole 11 is fixedly connected to the connecting rod 12.

[0026] When the stamping is completed, the lifting plate 4 drives the upper module 5 to move upward, and at the same time drives the vertical plate 10 to move upward. Since the bottom of the through hole 11 is inclined, as the vertical plate 10 moves, the inner wall of the through hole 11 will squeeze the outer surface of the cylindrical block 13, so that the two cylindrical blocks 13 can pull the two lower modules 7 to move in opposite directions, thereby avoiding the situation where the stamped hardware is stuck in the groove between the two lower modules 7 and is difficult to remove.

[0027] An inner groove 14 is provided in the middle of the front side of the block 6, and square holes 15 communicating with the inner groove 14 are provided on both sides of the top of the block 6. Folding plates 16 are provided on both sides of the inner wall of the inner groove 14, and the other end of the folding plate 16 passes through the square hole 15 and is fixedly connected to a clamping plate 17. The folding plate 16 is connected to the block 6 through a driving mechanism.

[0028] By moving the two folding plates 16 toward each other, the two clamping plates 17 can be moved toward each other to approach and contact the hardware to be stamped, so that the hardware can be straightened so that the edge of the hardware is parallel to the edge of the lower module 7, avoiding the hardware being placed crookedly and affecting the subsequent stamping quality.

[0029] The driving mechanism includes a driving motor 18, which is fixedly installed in the middle of the front side of the block 6. The output shaft of the driving motor 18 is fixedly sleeved with a bidirectional lead screw 19 located inside the inner groove 14, and two folding plates 16 are respectively threadedly sleeved on both sides of the outer surface of the bidirectional lead screw 19.

[0030] By starting the driving motor 18, the bidirectional lead screw 19 can be rotated, so that the two folding plates 16 can drive the two clamping plates 17 to move toward or away from each other. When the two clamping plates 17 move toward each other, the hardware can be clamped and aligned.

[0031] Guide rods 20 are fixedly mounted on both sides of the top of the lifting plate 4 , and the tops of the guide rods 20 extend to the top of the frame 2 .

[0032] The design of the guide rod 20 can provide a good guiding effect on the lifting plate 4, thereby making the lifting plate 4 more stable when moving up and down.

[0033] When in use, the staff first places the hardware raw material on the top of the lower module 7, and then starts the drive motor 18. Due to the operation of the drive motor 18, the bidirectional screw 19 will rotate, so that the two folding plates 16 can drive the two clamping plates 17 to move towards each other, and then the hardware raw material can be clamped and aligned to avoid the hardware being skewed. After the hardware is aligned, the drive motor 18 is started again to reverse the bidirectional screw 19 to restore the folding plate 16 to its original position, and then the hydraulic cylinder 3 is started to make the lifting plate 4 drive the upper module 5 to move downward to align the hardware. The raw material is stamped. After the stamping is completed, the hydraulic cylinder 3 is started so that the lifting plate 4 drives the upper module 5 and the vertical plate 10 to move upward. Since the bottom of the through hole 11 is inclined, as the vertical plate 10 moves, the inner wall of the through hole 11 will squeeze the outer surface of the cylindrical block 13, so that the two cylindrical blocks 13 can pull the two lower modules 7 to move in opposite directions under the guidance of the slider 9, thereby avoiding the situation where the stamped hardware is stuck in the groove between the two lower modules 7 and is difficult to remove, so that the staff can cut the hardware and improve the work efficiency.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
