DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0029] The pot handle mounting hole punching device is a device for punching holes in the handle iron sheet of the pot.

[0030] In the prior art, in order to prevent the iron sheet from shifting or warping during punching, the iron sheet needs to be fixed manually with a clamp before punching, resulting in the punching process generally being divided into two steps, namely, one fixing and the other punching. When dealing with batch punching, the two-step punching operation affects the overall punching efficiency.

[0031] In response to the above technical problems, this application provides a device for punching a mounting hole for a cookware handle. Figure 1 The figure shows the overall structure of the punching device for the mounting hole of the pot handle. Figure 1 The pot handle mounting hole punching device includes:

[0032] A base 100, on which a handle iron sheet 110 to be punched is placed;

[0033] The support frame 200 is installed above the base 100. A hydraulic cylinder 210 with its output end facing the handle iron sheet 110 is installed on the support frame 200. The output end of the hydraulic cylinder 210 is connected to a connecting plate 220 and a punch rod 230 from top to bottom.

[0034] The iron sheet is placed at a predetermined position, that is, directly below the punch rod 230 , and the connecting plate 220 and the punch rod 230 are driven downward by the output end of the hydraulic cylinder 210 , and the punch rod 230 is used to impact the handle iron sheet 110 to complete the punching.

[0035] Figure 2 shows a schematic structural diagram of the pre-fixing mechanism; Figure 2 The pre-fixing mechanism includes:

[0036] A support plate 310 , the support plate 310 is vertically disposed on one side of the hydraulic cylinder 210 ;

[0037] An L-shaped slideway 320 is provided on the support plate 310 and has a corner;

[0038] A sliding rod 330 is disposed transversely and slidably connected to the L-shaped slideway 320;

[0039] The pressure rod 350 is disposed on a side of the support plate 310 away from the connecting plate 220 and connected to one end of the sliding rod 330 . The lower edge of the pressure rod 350 is lower than the lower edge of the punching rod 230 .

[0040] The connecting member 360 is rotatably connected to the other end of the sliding rod 330. The other end of the connecting member 360 is rotatably connected to the connecting plate 220. The connecting member 360 is arranged to be gradually tilted in the direction from the connecting plate 220 toward the sliding rod 330.

[0041] When the punch rod 230 punches a hole, the pressure rod 350 is driven to slide along the track of the L-shaped slideway 320 . When the slide rod 330 slides to a corner, the pressure rod 350 stops moving and fixes the handle iron sheet 110 in advance.

[0042] When the punch rod 230 is driven to move downward to punch a hole, the connecting piece 360 ​​pulls the slide rod 330 and the pressure rod 350 to move along the trajectory of the L slideway 320. When the slide rod 330 moves to the corner of the L slideway 320, the pressure rod 350 contacts the handle iron sheet 110 and pre-fixes it. As the connecting plate 220 continues to move downward, the slide rod 330 is pulled by the connecting piece 360 ​​to slide horizontally, that is, the height of the pressure rod 350 no longer changes. Therefore, since the position of the slide rod 330 cannot change vertically, the pressure rod 350 350 can stably fix the handle iron sheet 110. Through the above design, a pressure rod 350 is set on one side of the punch rod 230 and is started synchronously with it. The pressure rod 350 can fix and press the handle iron sheet 110 in advance, eliminating the original step of manually fixing the iron sheet with a clamp, and reducing the original two steps to one step. The stamping efficiency is improved while ensuring the fixing effect. At the same time, the pressure rod 350 no longer moves after contacting the handle iron sheet 110, ensuring that the handle iron sheet 110 is fixed without shaking.

[0043] It should be noted that, in one stroke, the connecting member 360 is always arranged to be tilted in an incremental manner along the direction from the connecting plate 220 toward the sliding rod 330 .

[0044] In one embodiment, the corners of the L-slide 320 may be arc-shaped.

[0045] Figure 3 shows a schematic structural diagram of the horizontal slide 341; Figure 3 In the figure, the top of the pressure rod 350 is connected to the pressure block 340 , a horizontal slide 341 is opened in the pressure block 340 , and one end of the sliding rod 330 is slidably connected to the horizontal slide 341 .

[0046] When the slide rod 330 slides along the horizontal slide of the L slide 320, the slide rod 330 can slide in the horizontal slide 341, that is, the pressure block 340 slides relative to the slide rod 330 on the horizontal plane to eliminate the traction force on the horizontal plane brought by the slide rod 330 to the pressure rod 350, and prevent the pressure rod 350 from sliding horizontally on the surface of the handle iron sheet 110.

[0047] Figure 3 Combine Figure 2The support plate 310 is provided with a vertical slide 311 , which is slidably connected to the pressing block 340 , forcing the pressing block 340 and the pressing rod 350 to move only vertically.

[0048] Figure 4 shows a schematic structural diagram of the pressure rod 350; Figure 4 In the embodiment, the pressure rod 350 includes a sleeve 351 and an inserting rod 352, and the inserting rod 352 is rotatably connected to the sleeve 351;

[0049] The sleeve 351 and the insertion rod 352 rotate relative to each other to adjust the length of the pressing rod 350 .

[0050] During use, when the sleeve 351 and the insertion rod 352 are forced to rotate relative to each other, the overall length of the pressure rod 350 can be adjusted to adapt to handle iron sheets 110 of different thicknesses, thereby improving the applicability of the device.

[0051] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
