Description

Technical Field

[0001] The utility model relates to the technical field of die disassembly and assembly auxiliary devices, in particular to a stamping die that is convenient to disassemble. Background Technique

[0002] A stamping die is a special process equipment that processes materials (metal or non-metal) into parts (or semi-finished products) in cold stamping processing, called a cold stamping die (commonly known as a cold punching die). There are many forms of stamping dies, and stamping dies are also classified according to three aspects: working nature, die structure, and die material. The structure of the stamping die in the prior art is often relatively fixed, and the disassembly performance is poor, resulting in poor flexibility of the overall die. At the same time, after a long use time, the service life cannot be guaranteed.

[0003] In the prior art, a complex fastener structure is used to install the die on the stamping machine, which increases the labor intensity of the staff during later disassembly and maintenance. Therefore, it is particularly important to design a stamping die that is convenient to disassemble to solve the above technical problems. Content of the Utility Model

[0004] The purpose of the utility model is to solve the problem that a complex fastener structure is used to install the die on the stamping machine in the prior art, which increases the labor intensity of the staff during later disassembly and maintenance, and to propose a stamping die that is convenient to disassemble.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: a stamping die that is convenient to disassemble, including a base, guide columns are symmetrically and fixedly connected to the base, a fixed plate is fixedly connected to the guide columns, a hydraulic cylinder is fixedly connected to the fixed plate, a sliding rod is slidably connected in the hydraulic cylinder, a frame is fixedly connected to the end of the sliding rod, a limiting frame is installed between adjacent guide columns through a bracket, an upper die is detachably connected in the frame, a lower die is detachably connected in the limiting frame, rectangular grooves are symmetrically distributed on the top of the upper die, a limiting groove is arranged above the rectangular grooves, and the width of the rectangular grooves is greater than the width of the rectangular grooves.

[0006] Preferably, an oil cylinder is fixedly connected to the frame, a piston rod is slidably arranged in the oil cylinder, the end of the piston rod is designed in a T-shaped structure, and the shape of the end of the piston rod fits the shapes of both the rectangular groove and the limiting groove.

[0007] Preferably, the size of the end of the piston rod is greater than the width of the limiting groove, and the end of the piston rod is clamped and limited in the limiting groove.

[0008] Preferably, a convex block is fixedly connected to the bottom of the lower die, the convex block is mutually limited with the limiting frame, and the convex block is detachably connected in the limiting frame through a bolt.

[0009] Preferably, handle frames are symmetrically installed on the limiting frame, a sleeve frame is fixedly connected to the frame, the sleeve frame is slidably arranged on the guide post, and when the bottom of the sleeve frame abuts against the handle frame, it means that the upper die reaches the limit position of the lower die.

[0010] Compared with the prior art, the advantages and positive effects of the present utility model are as follows.

[0011] 1. In the present utility model, during use, a frame structure is installed below the sliding rod, and combined with the oil cylinder and piston rod structures on the frame, the piston rod moves upward to limit and fixedly connect the upper die in the frame. Then, the convex block of the lower die is inserted into the limiting frame, and the lower die is installed and limited in the limiting frame by bolts, completing the installation and limitation of the upper die and the lower die in the frame and the limiting frame.

[0012] 2. In the present utility model, during use, the hydraulic cylinder drives the sliding rod to drive the frame downward until the bottom of the sleeve frame abuts against the handle frame, which means that the upper die reaches the limit position of the lower die.

[0016] In order to more clearly understand the above-mentioned objects, features, and advantages of the present utility model, the present utility model will be further described below with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0017] In the following description, many specific details are set forth in order to provide a thorough understanding of the present utility model. However, the present utility model may also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited to the limitations of the specific embodiments disclosed in the following specification.

[0018] The present utility model provides a stamping die that is convenient to disassemble, including a base 1. Guide columns 101 are symmetrically and fixedly connected to the base 1. A fixing plate 102 is fixedly connected to the guide columns 101. A hydraulic cylinder 2 is fixedly connected to the fixing plate 102. A sliding rod 201 is slidably connected in the hydraulic cylinder 2. A frame 3 is fixedly connected to the end of the sliding rod 201. A limiting frame 401 is installed between adjacent guide columns 101 through a bracket 4. An upper die 301 is detachably connected in the frame 3. A lower die 302 is detachably connected in the limiting frame 401. A convex block 5 is fixedly connected to the bottom of the lower die 302. The convex block 5 and the limiting frame 401 are mutually limited. The convex block 5 is detachably connected in the limiting frame 401 through a bolt 501. Rectangular grooves 303 are symmetrically distributed on the top of the upper die 301. A limiting groove 304 is arranged above the rectangular grooves 303. The width of the rectangular grooves 303 is greater than the width of the rectangular grooves 303. An oil cylinder 305 is fixedly connected to the frame 3. A piston rod 306 is slidably arranged in the oil cylinder 305. The end of the piston rod 306 is designed in a T-shaped structure. The outer shape of the end of the piston rod 306 fits the shapes of both the rectangular grooves 303 and the limiting groove 304. By the end of the piston rod 306 abutting against the inner wall of the limiting groove 304, the fixing and limiting work of the upper die 301 in the frame 3 is completed.

[0019] When the stamping die that is convenient to disassemble is actually used, a rectangular groove 303 and a limit groove 304 start on the upper die 301. Both of the above two groove structures are through-groove structures. The staff manually operates an auxiliary tool to slide the piston rod 306 in the oil cylinder 305 into the rectangular groove 303 and the limit groove 304. When the upper die 301 completely enters the frame 3, then the staff controls the oil cylinder 305 to start working, driving the piston rod 306 to move upward, so that the end structure of the piston rod 306 abuts against the inner wall of the limit groove 304, so that the overall structure of the upper die 301 is limited and fixed in the frame 3. Then the staff operates the auxiliary tool to install the lower die 302 into the limit frame 401. The convex block 5 of the lower die 302 is embedded in the limit frame 401, and then the bolt 501 is operated to screw into the limit frame 401, so that the lower die 302 is installed and limited in the limit frame 401. Then a sheet is placed between the upper die 301 and the lower die 302, and then the hydraulic cylinder 2 drives the sliding rod 201 to drive the frame 3 to descend until the bottom of the sleeve 503 abuts against the handle frame 502, which means the upper die 301 reaches the limit position of the lower die 302. At this time, the stamping process of the sheet has been completed. When replacement or maintenance is needed, an external auxiliary tool is used, and the upper die 301 and the lower die 302 are disassembled in turn in cooperation with the oil cylinder 305 component structure. By installing a frame 3 structure at the lower position of the sliding rod 201, combined with the structure of the oil cylinder 305 and the piston rod 306 on the frame 3, the piston rod 306 moves upward to limit and fixedly connect the upper die 301 in the frame 3. Then the convex block 5 of the lower die 302 is inserted into the limit frame 401, and the lower die 302 is installed and limited in the limit frame 401 by combining the bolt 501, completing the installation and limitation of the upper die 301 and the lower die 302 in the frame 3 and the limit frame 401. Compared with the conventional installation and limitation method that is not easy to disassemble, the technical solution adopted by the present utility model can quickly disassemble and assemble the die structure in the corresponding processing equipment, reducing the disassembly and assembly difficulty of the staff and liberating the labor intensity of the staff.

[0020] As Figure 1-2 shown, the size of the end of the piston rod 306 is larger than the width of the limit groove 304. The end of the piston rod 306 is clamped and limited in the limit groove 304. The handle frames 502 are symmetrically installed on the limit frame 401. A sleeve 503 is fixedly connected to the frame 3. The sleeve 503 is slidably arranged on the guide post 101. When the bottom of the sleeve 503 abuts against the handle frame 502, it means the upper die 301 reaches the limit position of the lower die 302.

[0021] The effect achieved by the entire Embodiment 1 is that during use, the hydraulic cylinder 2 drives the sliding rod 201 to drive the frame 3 downward. When the bottom of the sleeve 503 abuts against the handle frame 502, the upper die 301 reaches the limit position of the lower die 302. The lower end of the sleeve 503 abuts against the handle frame 502 to limit the downward movement of the punch, ensuring the safe progress of the stamping work.

[0022] Working principle: There are a rectangular groove and a limit groove on the upper die. Both of the above groove structures are through-groove structures. The staff manually operates the auxiliary tool to slide the piston rod in the oil cylinder into the rectangular groove and the limit groove. When the upper die completely enters the frame, then the staff controls the oil cylinder to start working, driving the piston rod to move upward, so that the end structure of the piston rod abuts against the inner wall of the limit groove, fixing the overall structure of the upper die in the frame. Then the staff operates the auxiliary tool to install the lower die into the limit frame. The convex block of the lower die is embedded in the limit frame, and then the bolt is operated to screw into the limit frame to limit and fix the lower die in the limit frame. Then a sheet is placed between the upper die and the lower die, and then the hydraulic cylinder drives the sliding rod to drive the frame downward. When the bottom of the sleeve abuts against the handle frame, the upper die reaches the limit position of the lower die. At this time, the stamping work on the sheet has been completed. When replacement or maintenance is required, the upper die and the lower die are disassembled in sequence by the external auxiliary tool and in cooperation with the oil cylinder assembly structure.
