DETAILED DESCRIPTION

[0022] The following is combined with Figures 1 to 5 The utility model is described in detail.

[0023] The utility model is a double-position rotatable sheet punching machine, comprising a body 1, a connecting column 11 is provided at the bottom of the body 1, extensions are provided at the front and rear ends of the body 1, the extensions are provided with a punch 12 that can be raised and lowered, rockers 13 that can drive the punch 12 are provided on both sides of the body 1, a detachable cutting die 14 is provided below the punch 12, comprising a base 2, the base 2 is fixedly connected to the connecting column 11, a rotatable supporting plate 3 is provided on the base 2, and a cutting plate 3 that can cooperate with the cutting die 14 is provided on the supporting plate 3. The two rockers 13 of the sheet punching machine of the utility model cooperate with the two punches 12 to form two sheet punching stations, which can be used by two people. A first positioning block 111 is provided at the bottom of the connecting column 11, and a second positioning block 32 corresponding to the first positioning block 111 is provided in the middle of the support plate 3. The second positioning block 32 is provided with a plurality of accommodating grooves 33, and elastic members 34 are provided in the accommodating grooves 33. Steel balls 35 are provided on top of the elastic members 34. A groove 112 corresponding to the accommodating grooves 33 is provided at the bottom of the first positioning block 111. In the present utility model, a plurality of knife blocks 31 are provided at equal intervals on the support plate 3, and the number of knife blocks 31 is consistent with the number of steel balls 35. By rotating the support plate 3, the position of the knife blocks 31 can be adjusted, thereby changing the specifications of the knife blocks 31 below the punch 12. Multiple punching modes can be switched by simply replacing the cutting die 14, without disassembling the knife blocks 31, which is convenient to use. In the specific replacement positioning structure of the tool holder 31, when the position of an individual tool holder 31 corresponds to that of the cutting die 14, the steel ball 35 is in the groove 112. When the support plate 3 rotates, the steel ball 35 leaves the groove 112, and the bottom of the first positioning block 111 squeezes the steel ball 35. The support plate 3 will have a certain rotational resistance during this rotation process. After the support plate 3 rotates to a specific angle, the elastic member 34 pushes the steel ball 35 into the groove 112, so that the first positioning block 111 is hinged to the second positioning block 32, and the tool holder 31 completes a position replacement.

[0024] The first positioning block 111 and the second positioning block 32 are both regular octagons, and eight accommodating grooves 33 are evenly spaced on the second positioning block 32. In this embodiment, eight knife holders 31 are also provided, and the support plate 3 rotates 45 degrees to complete a position change. The user can use the shape of the first positioning block 111 and the second positioning block 32 to help determine whether the knife holder 31 is correctly replaced, so as to avoid misalignment between the cutting die 14 and the knife holder 31.

[0025] The support plate 3 is equipped with eight fixed blocks 36 at equal intervals along its edge, and the base 2 is provided with anti-slip grooves 22 along its edge. The user can rotate the support plate 3 by pressing their thumb on the anti-slip grooves 22 and hooking their other fingers on the fixed blocks 36. This rotation method significantly reduces the thrust applied by the user to the punch, preventing the punch from shifting when rotating the support plate 3.

[0026] Identification symbols 113 are provided on the first and second positioning blocks 111, 32. In this embodiment, identification symbols 113 are provided on all eight faces of the octagonal first and second positioning blocks 111, 32. The identification symbols 113 on the first positioning block 111 can be used to identify the orientation of the press, making it easier for the user to identify the positions of the two stamping stations and prevent confusion between them. The identification symbol 113 on the second positioning block 32 can be used to identify the serial number of the tool holder 31, making it easier for the user to identify the specifications of the tool holder 31. This makes it easy to use.

[0027] The two rockers 13 are symmetrical with respect to each other, and a ball head 131 is provided at the end of the rocker 13. The rocker 13 is tilted toward the corresponding punch 12. The user holds the ball head 131 and presses the rocker 13 downward to press the corresponding punch 12 downward.

[0028] A fixing rod 15 is provided at the center of the top of the body 1. When the user performs the punching operation, he can hold the fixing rod 15 with one hand and press the rocker 13 with the other hand. The fixing rod 15 can stabilize the punching machine during the punching process to prevent the punching machine from shaking.

[0029] The base 2 is provided with an annular protrusion 21, and the bottom of the support plate 3 is provided with an annular groove 37112 corresponding to the annular protrusion 21. The annular protrusion 21 is engaged with the annular groove 37112, so that the support plate 3 maintains 360° balance and the rotation structure of the support plate 3 is stable.

[0030] More specifically, the annular protrusions 21 are provided at two locations, one inner and one outer. The outer annular protrusion 21 is located below the cutter seat 31, while the inner annular protrusion 21 is located near the bottom of the second positioning block 32. This allows the support plate 3 to remain stable and not easily shake or tilt when the support plate 3 rotates and the cutter die 14 punches the sheet.

[0031] The base 2 is provided with a plurality of legs 23 at the bottom, and anti-skid pads 24 are provided at the bottom of the legs 23. The punching machine of the present invention is generally placed on a table in a laboratory for use. The anti-skid pads 24 can provide a high friction resistance between the legs 23 and the table, thereby preventing the base 2 from sliding to a large extent.

[0032] The knife block 31 is equipped with a removable storage box 311. A positioning tab 312 is provided on the outer wall of the knife block 31 to position the storage box 311. The center of the knife block 31 and the storage box 311 both have slots corresponding to the cutting die 14. After the cutting die 14 punches the test material, the cut material remains in the slots of the storage box 311. The material can be accessed by removing the storage box 311 without any other tools.

[0033] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there may be changes in the specific implementation methods and application scopes. The contents of this specification should not be understood as limiting the present invention.
