Technical Field
[0001] This utility model relates to the field of hole processing technology, specifically a stamping fixture for hole processing. Background Technology
[0002] Machining refers to the process of changing the shape, size or properties of a workpiece through a mechanical device. In the machinery manufacturing industry, hole machining is a very common and important process, which requires the use of stamping fixtures.
[0003] Existing stamping fixtures often suffer from poor fit between the punch and die in some cases, resulting in large deviations in hole dimensions and irregular shapes, making it difficult to meet the production requirements of high-precision products. Furthermore, existing fixtures are ineffective at securing the workpiece during stamping, easily causing workpiece displacement. This not only affects the hole machining quality but can also damage the punch in severe cases, increasing production costs and time. Moreover, punch replacement is difficult, and maintenance is inconvenient, thus reducing the efficiency of the stamping fixture.
[0004] Therefore, we urgently need to provide a stamping fixture for hole machining. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figures 1-4 This utility model provides a technical solution:
[0021] A stamping fixture for hole processing includes a die base plate 1, a die fixing plate 2 is provided on the top of the die base plate 1, the bottom of the die fixing plate 2 is connected to the top of the die base plate 1, a punch fixing plate 3 is provided on the top of the die fixing plate 2, a punch back plate 4 is provided on the top of the punch fixing plate 3, and the bottom of the punch back plate 4 is connected to the bottom of the punch fixing plate 3.
[0022] The top of the punch back plate 4 is provided with a die shank 5, the bottom of the die shank 5 is connected to the top of the punch back plate 4, and the bottom of the punch fixing plate 3 is provided with a guide post 6, the top of the guide post 6 is connected to the bottom of the punch fixing plate 3, so as to better guide the work and thus better punch the work.
[0023] A punch guide plate 7 is provided on the top of the die fixing plate 2. The bottom of the punch guide plate 7 is connected to the top of the die fixing plate 2. A die template 8 is provided on one side of the die fixing plate 2. One side of the die template 8 is connected to one side of the die fixing plate 2. A pressure block 9 is provided on one side of the die fixing plate 2. A pressure spring 10 is fixedly installed between the top of the pressure block 9 and one side of the die fixing plate 2, so as to better limit and fix the product 11, and thus better process it.
[0024] A product 11 is provided on one side of the concave template 8, and a limit box 12 is provided on one side of the punch fixing plate 3. One end of the limit box 12 is connected to one side of the punch fixing plate 3, and a limit rod 13 is slidably connected to the inner wall of the limit box 12.
[0025] A baffle plate 14 is fixedly installed on the outer wall of the limiting rod 13. A spring is fixedly installed between one side of the baffle plate 14 and the inner wall of the limiting box 12, so that it can be used better and can be disassembled and replaced more conveniently.
[0026] The punch fixing plate 3 has a punching punch 15 at the bottom. A limit hole is opened on one side of the punching punch 15. One end of the limit rod 13 is inserted into the inner wall of the limit hole, so that the punching punch 15 can be quickly and conveniently disassembled and assembled, and thus better punching work can be carried out.
[0027] When using this stamping fixture for hole machining, first install the die shank 5 of the fixture on the slide block of the stamping equipment. Place the product 11 to be processed on the die cavity 8, adjust the position, and start the stamping equipment. The slide block drives the die shank 5 to move downward, and the punch assembly descends accordingly. During the descent, the pressure block 9 contacts the workpiece first, and the pressure spring 10 further compresses, generating pressure that presses the product 11 firmly onto the die cavity 8. Then, under the guidance of the punch guide plate 3 and the guide post 6, the punching punch 15 accurately enters the die cavity to punch the product 11. After stamping is completed, the slide block drives the die shank 5 to move upward, the punch assembly rises, and the pressure... The material spring 10 returns to its original state, lifting the pressure block 9. At this time, the processed workpiece can be taken out, completing one hole processing operation. If it is necessary to replace the punch 15, the limit rod 13 is pulled to slide on the inner wall of the limit box 12. The sliding of the limit rod 13 drives the baffle plate 14 to move. The movement of the baffle plate 14 compresses the spring. The movement of the limit rod 13 allows it to be pulled out from one side of the punch 14, thereby canceling the limit fixation of the punch 14. At this time, the punch 14 can be removed from the punch fixing plate 4. When it is necessary to install, the above steps are repeated in reverse to install it, so as to process holes of different specifications.
