Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to a cylinder punching mechanism. Background Art

[0002] Punching is a common metalworking method used to create holes in metal plates or pipes. When punching holes in tubular materials, good positioning is crucial for ensuring accurate placement of the holes. However, existing techniques for punching multiple holes in the same pipe require multiple positioning of the pipe based on the desired hole locations, as the punch is fixed in position. This is not only time-consuming and labor-intensive, but also hinders production efficiency. Utility Model Content

[0003] The utility model discloses a cylindrical punching mechanism, which solves the technical problem in the prior art that the punching positioning operation is time-consuming and labor-intensive and is not conducive to improving production efficiency. It has a reasonable structure, convenient positioning, and is conducive to improving production efficiency. The technical solution adopted is as follows:

[0004] A cylinder punching mechanism includes a base, a punch and a positioning shaft. The base is fixedly connected to a back plate upward, and the back plate is vertically connected to a die base. The die base includes an arc surface adapted to the inner wall of the cylinder. The cylinder can be sleeved on the die base to maintain a set height position. The positioning shaft can pass through the through hole on the cylinder to position the cylinder on the die base. The die base is also provided with a first groove. The punch is arranged above the first groove to punch a hole in the area of ​​the cylinder corresponding to the position of the first groove.

[0005] On the basis of the above technical solution, the positioning shaft is plugged into the mold base or the positioning shaft is fixed on the mold base.

[0006] On the basis of the above technical solution, when the positioning shaft is plugged into the mold base, the positioning shaft is plugged and adsorbed on the mold base under the action of magnetic force.

[0007] On the basis of the above technical solution, it also includes two guide columns, which are arranged on both sides of the back plate and fixed to the base downward. The punch is fixed to the mounting plate, and the guide columns pass through the mounting plate and are slidably connected to the mounting plate up and down.

[0008] On the basis of the above technical solution, a linear bearing is provided on the sliding connection between the guide column and the mounting plate, and a compression spring is provided on the outer sleeve of the guide column between the end face of the linear bearing and the base.

[0009] Based on the above technical solution, the back plate and the base are connected via a rib plate.

[0010] Based on the above technical solution, the mold base is detachably connected to the back plate.

[0011] On the basis of the above technical solution, a concave cavity is provided on the base. When the cylinder is sleeved on the mold base, the cylinder can be partially accommodated in the concave cavity and cooperate with the inner wall surface of the concave cavity.

[0012] Beneficial effects

[0013] The utility model has a reasonable structure. The back plate can axially position the cylinder. The cylinder is sleeved on the die base to keep the cylinder at a set height so as to cooperate with the punch to perform punching. In addition, the positioning shaft can pass through the through hole on the cylinder to position the circumferential position of the cylinder. This not only facilitates positioning, but also greatly simplifies the structure, which is conducive to reducing costs and improving production efficiency.

[0024] like Figures 2 and 3The cylindrical punching mechanism shown includes a base 1, a punch 2 and a positioning shaft. The base 1 is fixed with a back plate 4 upwardly. The back plate 4 and the base 1 are connected by a rib plate 9 to improve the connection reliability between the back plate 4 and the base 1.

[0025] A die base 5 is vertically connected to the back plate 4, and the die base 5 and the back plate 4 are detachably connected. Specifically, one end of the die base 5 is plugged into the back plate 4, and also includes a number of top screws. The top screws pass through the back plate 4 and abut against the outer edge of the die base 5, thereby fixing the die base 5 and the back plate 4. In this way, an appropriate die base 5 can be selected according to the diameter of the cylinder to be punched, and the use flexibility is good.

[0026] like Figure 2 As shown, the mold base 5 includes a curved surface that mates with the inner wall of the cylinder. The cylinder is mounted on the mold base 5, and the curved surface of the mold base 5 mates with the inner wall of the cylinder, maintaining the cylinder at a set height. In addition, the base 1 is provided with a cavity 10. When the cylinder is mounted on the mold base 5, the cylinder can be partially accommodated in the cavity 10 and mate with the inner wall of the cavity 10. The inner cavity 10 includes an end surface that is coplanar with the back plate 4, which can better position the cylinder axially.

[0027] like Figure 2 As shown, the mold base 5 includes a first groove 51 and a second groove 52. In this embodiment, the positioning shaft can pass through the through-hole in the cylinder and be inserted into the second groove 52. This fixes the positioning shaft to the mold base 5 and simultaneously positions the cylinder circumferentially. The bottom surface of the second groove 52 is provided with a magnet. When the positioning shaft extends into the second groove 52, it can be inserted and adsorbed in the second groove 52 under the action of the magnetic force. In other embodiments of the present invention, the positioning shaft is fixed to the mold base 5 and extends radially along the arc surface of the mold base 5. When the positioning shaft passes through the through-hole in the cylinder, the cylinder can be positioned circumferentially.

[0028] The punch 2 is arranged above the first groove 51. When the cylinder is positioned axially and circumferentially on the die base 5, the punch 2 can punch downward and extend into the first groove 51 to punch a hole in the area of ​​the cylinder corresponding to the position of the first groove 51.

[0029] like Figure 2 and 3 As shown, it also includes two guide columns 6, which are arranged on both sides of the back plate 4 and are fixedly connected to the base 1 downward. The punch 2 is fixedly connected to the mounting plate 7. The guide columns 6 pass through the mounting plate 7 and are slidably connected to the mounting plate 7 up and down. A linear bearing 8 is provided at the sliding connection between the guide column 6 and the mounting plate 7, and a compression spring is provided on the outer sleeve of the guide column 6 between the end face of the linear bearing 8 and the base. The guide column 6 can play a guiding role when the punch 2 punches downward. The setting of the compression spring can buffer the downward impact force of the punch 2 and play a shock-absorbing effect.
