Description

Technical Field

[0001] The utility model relates to a punching tool for the side of an upper cover of a double-layer water boiler. Background Art

[0002] A double-layer water boiler is a large-scale water-boiling product that heats water by adding cold water to the container through a pipe. The side of its upper cover requires two sets of symmetrical, equal-height holes to connect to the clamping block to ensure a reliable connection with the container body and prevent steam from escaping when the upper cover is opened, causing damage. Currently, the symmetrical connection holes on the side of the upper cover are processed by marking and drilling. This method has the following disadvantages: 1. The marking itself has errors, making it difficult to ensure symmetry and concentricity between each set of holes; 2. The upper cover is a thin-walled component that is prone to deformation during clamping, and the quality of the drilled holes cannot be guaranteed; 3. The processing of the connection holes requires two steps: marking and drilling, which is extremely inefficient and requires high technical skills from the operator. Summary of the Invention

[0025] The power unit transmits power: when the press presses down the guide columns 312 on the left and right sides, the guide columns 312 press down the outer end of the movable block 311 to make the movable block 311 rotate around the rotating shaft 315, and the inner end of the movable block 311 pushes the top block 316 and the slider 310 to move toward the middle along the base 1, and then pushes the clamping unit and the punching unit to move toward the middle, that is, toward the upper cover of the double-layer water boiler, so as to achieve the clamping and punching of the upper cover.

[0026] Example 4

[0027] from Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 It can be seen that the symmetrical punching device of the present invention has a protrusion at the bottom of the slider 310 and a groove on the top surface of the base 1 , and the protrusion cooperates with the groove.

[0028] The slider 310 moves along the base 1 through the cooperation between the protrusion and the groove, ensuring its stable movement without shaking, thereby ensuring the quality of subsequent pressing and punching.

[0029] Example 5

[0030] from Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 It can be seen that the symmetrical punching device of the present invention: the pressing unit includes a fixed block I 321, an arc-shaped pressing block 322, and a spring 323.

[0031] The slider 310 is connected to the fixed block I 321 by a spring 323, so that the force transmitted from the top block 316 is buffered by the spring 323 and then transmitted to the fixed block I 321, and the upper cover is pressed by the arc-shaped pressing block 322, thereby preventing the force of the top block from being directly transmitted to the arc-shaped pressing block to press the upper cover, causing it to be subjected to excessive force and deformed.

[0032] Example 6

[0033] from Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 It can be seen that the symmetrical punching device of the present invention: the punching unit includes punching needles 331 symmetrically arranged front and back, the punching needles 331 are located in the grooves on the inner surfaces of the front and rear fixed brackets 30, and the small end face of the right end of the slider 310 is connected to the end of the punching needle 331.

[0034] The slider 310 drives the punching needle 331 to move toward the middle, so that when the arc-shaped pressing block 322 presses against the upper cover, the punching needle 331 instantly punches out the hole on the side of the upper cover under the action of the thrust.

[0035] The punching pin 331 is made of alloy steel through heat treatment and has a certain hardness.

[0038] When the slider 310 pushes the arc-shaped pressure block 322 to move toward the middle, the lateral positioning block 317 also moves and compresses the return spring 319. In this way, after the punching is completed and the press leaves the guide column, the return spring 319 drives the lateral positioning block 317, the slider 310, and the punch needle 331 to quickly return to their original positions under the reaction of the compression force, and at the same time, the top block 316 quickly returns to its original position.

[0039] The working principle of the symmetrical punching device of the present invention is: first, the upper cover 4 is placed on the circular positioning die base 2, at this time, the press presses down the guide columns 312 on the left and right sides, the guide columns press down the outer end of the movable block 311, and the movable block rotates around the rotating shaft 315, and the inner end of the movable block pushes the top block 316 and the slider 310 to move toward the middle along the base 1. At this time, the fixed block 321 and the arc-shaped pressure block 322 are pushed toward the middle by the spring 323, and the arc-shaped pressure blocks on both sides jointly press the upper cover; at the same time, the slider drives the punch needle 331 to move toward the middle, and a total of four punch needles on the left and right ends work at the same time, and four symmetrical holes are instantly punched out at the specified position of the upper cover; when the slider moves toward the middle, the horizontal positioning block 317 also moves to compress the return spring 319.
