[0011] As a further solution of the utility model: one end of the limit rod is connected to a round cap, the end of the screw rod away from the pressure plate is connected to a nut, and one end of the bidirectional screw rod is connected to a handle.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The precise punching equipment for the production of protective clothing is equipped with a bidirectional screw, a splint, a limit groove, a limit block, a limit rod, a limit hole and a spring. When holes of different sizes need to be punched, the round cap is pulled to drive the limit rod so that the limit rod is separated from the limit hole, the installation column is removed from the sleeve, and different sizes of punching rods are replaced. The limit groove is aligned with the limit block, and the installation column is inserted into the sleeve. The round cap is loosened to insert the limit rod into the limit hole to complete the installation of different sizes of punching rods. The handle is turned to drive the bidirectional screw to rotate. The two clamps are moved away from each other to release the fixation of the lower mold, the lower mold is removed from the inside of the support plate, the through hole with the same diameter as the punching rod is replaced, the lower mold is placed between the two clamps, and the handle is turned to drive the two clamps to move closer to each other to limit the lower mold, so that the replacement of through holes of different sizes can be completed. At this time, the electric push rod is started to drive the punching rod to move downward to perform punching. The punching equipment is convenient for replacing punching rods and through holes of different diameters, and thus can easily punch holes of different diameters, thereby improving applicability.

[0014] 2. The precise punching equipment for the production of protective clothing is equipped with threaded rods, connecting plates, movable plates and motors. The protective clothing is placed on the bottom of the pressing plate. The nut is turned to drive the screw to rotate, so that the pressing plate is pressed down to fix the protective clothing. The motor is started to drive the threaded rod to rotate, so that the connecting plate, movable plate and protective clothing move synchronously, and holes can be punched in different positions of the protective clothing, which improves practicality.

[0020] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0021] like Figure 1-4 As shown, the utility model provides a technical solution: a precision punching device for protective clothing production, including a support plate 1, four columns 7 are fixedly connected to the bottom of the support plate 1, one end of the column 7 is connected to a support foot 8, an L-shaped rod 2 is fixedly connected to the support plate 1, and an electric push rod 3 is fixedly connected to the L-shaped rod 2.

[0022] A sleeve 4 is connected to one end of the electric push rod 3, and two limit blocks 23 are fixedly connected inside the sleeve 4. A mounting column 25 is arranged inside the sleeve 4, and two limit grooves 26 are provided on the mounting column 25. Because the limit grooves 26 are provided, in cooperation with the limit blocks 23, when the mounting column 25 is inserted into the sleeve 4, the limiting action of the limit grooves 26 and the two-way screw rod 27 can make the limit hole 24 just align with the limit rod 20, thereby reducing the difficulty of operation. The limiting hole 24 is provided on the mounting column 25, and the connecting plate 13 is fixedly connected to the two movable plates 9. Two bearings 19 are sleeved on the two-way screw rod 27. Because the bearings 19 are provided, when the handle 28 is turned to drive the two-way screw rod 27 to rotate on the bearings 19, the friction is smaller, which is convenient for the staff to turn the handle 28.

[0023] One end of the mounting column 25 is fixedly connected to the punching rod 14, and the sleeve 4 is slidably connected to the limiting rod 20. One end of the limiting rod 20 is connected to the round cap 22. The end of the screw 18 away from the pressure plate 17 is connected to the nut 16. Because the nut 16 is provided with a plurality of grooves, the friction is increased, which makes it convenient for the staff to rotate the nut 16. One end of the bidirectional screw rod 27 is connected to the handle 28. Because the handle 28 is provided, when the handle 28 is turned to drive the bidirectional screw rod 27 to rotate, the handle 28 makes the bidirectional screw rod 27 easier to be rotated, thereby improving the convenience of operation. A spring 21 is sleeved on the limiting rod 20, and two splints 5 are slidably connected to the support plate 1, and the two splints 5 are provided with a lower mold 6.

[0024] A bidirectional screw rod 27 is threadedly connected to the two clamping plates 5, two movable plates 9 are slidably connected to the support plate 1, a waterproof box 10 is fixedly connected to the support plate 1, and because of the waterproof box 10, the waterproof box 10 can provide waterproof protection for the motor 11, so that the motor 11 is not easily damaged, the motor 11 is fixedly connected to the support plate 1, the output end of the motor 11 is connected to a threaded rod 12, the threaded rod 12 is threadedly connected to a connecting plate 13, a screw 18 is threadedly connected to the movable plate 9, one end of the screw 18 is connected to a pressing plate 17, and a through hole 15 is opened on the lower mold 6.

[0025] The working principle of the utility model is:

[0026] Place the protective clothing at the bottom of the pressing plate 17, turn the nut 16 to drive the screw 18 to rotate, so that the pressing plate 17 presses down to fix the protective clothing, start the motor 11 to drive the threaded rod 12 to rotate, so that the connecting plate 13 and the movable plate 9 move synchronously with the protective clothing, and then holes can be punched at different positions of the protective clothing. When holes of different sizes need to be punched, pull the round cap 22 to drive the limiting rod 20 so that the limiting rod 20 is separated from the limiting hole 24, remove the mounting column 25 from the sleeve 4, replace the punching rod 14 of different sizes, align the limiting groove 26 with the limiting block 23, insert the mounting column 25 into the sleeve 4, and loosen it. The round cap 22 is opened to allow the limiting rod 20 to be inserted into the limiting hole 24 to complete the installation of stamping rods 14 of different sizes. The handle 28 is turned to drive the bidirectional screw rod 27 to rotate, so that the two clamping plates 5 move away from each other, and the fixation of the lower mold 6 is released. The lower mold 6 is removed from the inside of the support plate 1, and the through hole 15 with the same diameter as the stamping rod 14 is replaced. The lower mold 6 is placed between the two clamping plates 5, and the handle 28 is turned to drive the two clamping plates 5 to move closer to each other to limit the lower mold 6. The replacement of through holes 15 of different sizes can be completed. At this time, the electric push rod 3 is started to drive the stamping rod 14 to move downward to perform punching.

[0027] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0028] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
