Background

The cooker cover is a cooker cover, a lifting buckle is often arranged on the cooker cover, the traditional cooker cover is an iron cooker cover, the cleaning is convenient, rust is easy to generate, food in the cooker and the state of the food are not visible, the heat preservation effect is poor, and heat is easy to dissipate. Therefore, the glass pot cover appears in the market, the glass pot cover can see food in the pot and the state of the food in the pot, and the glass cover is fragile under the action of external force, so that the metal guard edge is embedded outside the edge of the toughened glass cover body, the glass cover has the main functions of keeping the temperature of substances in the pot, preventing hot oil from splashing, protecting the glass cover and reducing the possibility of the glass cover crashing under the action of external force.

The metal bag Bian Zaizhi needs to be perforated in the preparation process, accumulated water in the glass cover can flow out from the inside of the hole conveniently, and the patent with the application number of CN1189437A provides a silica gel ring combined cover and a manufacturing method thereof. The manufacturing method comprises the following steps: 1) Providing a metal sheet body and cutting the metal sheet body into metal strips with corresponding sizes; 2) Welding two ends of the metal belt, stretching, forming and punching; 3) Polishing;

4) Placing the metal into a mould, and injecting silica gel to enable the silica gel to be combined on the metal after being formed; 5) After forming, embedding a metal inner layer by using a glass cover; 6) And (5) edge wrapping is carried out, so that the glass cover is tightly buckled on the metal.

According to the scheme, the metal sheet body is stretched before being perforated, but when the metal sheet body is perforated every time, deformation is brought to the metal sheet body, deformation superposition brought by a plurality of holes can lead to metal wrapping deformation, the metal wrapping edges are uneven up and down, the metal sheet is not attractive in use and can be not matched with the glass cover body, and the metal wrapping edge yield is low, so that a punching forming device for firstly perforating the metal wrapping edges and then stretching the metal wrapping edges is needed.

As shown in fig. 3 and 4:

Unlike embodiment 1, a detection area 16 is provided on the frame 1, a base 12 is provided on the frame 1, a tensioning wheel 10 in rotational connection is provided on the front surface of the base 12, a groove for the tensioning wheel 10 to move up and down is provided on the frame 1, a threaded hole 15 is provided on the back surface of the base 12, the threaded hole 15 is in threaded connection with the groove through a bolt 13, the bolt 13 can fix the base 12 on the frame 1 by the thread, the threaded hole 15, the bolt 13 and the groove enable the base 12 to move up and down, a detection area 16 for detecting whether the large hole 11 and the small hole 11 are correspondingly provided is provided on the frame 1, the length of a metal strip between the large punch 4 and the small punch 5 is recorded as a period, the large punch 4, the tensioning wheel 10, the small punch 5 and the detection area 16 are sequentially provided on the frame 1 from a feed port to a discharge port, the metal strip is sequentially wound on the large punch 4, the tensioning wheel 10 and the small punch 5, and the length of the metal strip between the detection area 16 and the small punch 5 is more than or equal to one period, the selected period is used as the detection area 16, therefore the detection area 16 should be provided on the frame 1, the motor 11 is provided with a second infrared sensor 19 and an infrared sensor 19 is provided on the frame 1, and is electrically connected to the second infrared sensor 19, and the second infrared sensor is provided on the frame 9. The tensioning wheel 10 tightens the metal strip between the two punches to control the interval of punching holes 11 between the large punch 4 and the small punch 5, so as to ensure that the interval between the holes 11 punched by the large punch 4 and the small punch 5 is fixed, after the metal strip is welded into a ring, the length of the metal strip between the large punch 4 and the small punch 5 is changed due to the setting of the tensioning wheel 10, and meanwhile, the positions of the tensioning wheel 10 can be adjusted (so that the tensioning wheel 10 moves up and down), so as to ensure that the large holes 11 and the small holes 11 on the metal ring 8 with different sizes are symmetrically arranged, and the metal strip always rotates along with the winding roller 2 to be discharged and then passes through the large punch 4, the tensioning wheel 10 and the small punch 5 to be discharged, the large punch 5 is used for punching the holes 11, and the metal strip always gives an upward force to the tensioning wheel 10, so that the length of the metal strip between the large punch 4 and the small punch 5 is changed, and the large holes 11 and the small holes 11 of the metal strip after each punching the holes 11 cannot be correspondingly arranged, therefore, when the infrared sensor 19 emits light which cannot pass through the detection area 16, the second motor 11 and the tensioning wheel 1 rotates, and the frame 13 are reset, and the frame 13 are simultaneously started. The mutual matching of the infrared sensor 19, the tensioning wheel 10 and the second motor 9 ensures that the distance between the large hole 11 and the small hole 11 which are punched by the large punch 4 and the small punch 5 each time is consistent, and the appearance is more attractive. The cooperation of the bolts 13, the base 12, the grooves and the threaded holes 15 enables the base 12 to move downwards when the tensioning wheel 10 rotates. When the infrared sensor 19 is arranged in the detection area 16 and the hole 11 cannot transmit light, the second motor 9 can be started in time, and the control accuracy is higher.

In order to ensure that the error is minimum, the infrared sensor 19 is preset in the outermost hole 11 of the detection area 16, namely, the hole 11 farthest from the small punch 5 or the hole 11 nearest to the small punch 5, when the light emitted by the infrared sensor 19 cannot pass through the hole 11, the second motor 9 starts to adjust the tensioning wheel 10, because the holes 11 punched by the punching machine are arranged in a closed manner, if the infrared sensor 19 is arranged in any hole 11 (marked as a, the holes 11 on two sides of the hole 11 are marked as B and C respectively), even if the hole 11 (a) is offset, the light emitted by the infrared sensor 19 may penetrate through the hole B or C, and the movement of the tensioning wheel 10 cannot be correctly identified, so that the infrared sensor 19 is arranged in the outermost hole 11 of the detection area 16, namely, the hole 11 farthest from the small punch 5 or the hole 11 nearest to the small punch 5, and the infrared sensor 19 is not arranged in the place where the holes 11 are distributed in a closed manner, the error measured by the infrared sensor 19 can be reduced, and the offset of each detection hole 11 is ensured to be accumulated in a single direction, and the tensioning wheel 11 cannot be disturbed by other holes 11, so that the movement of the tensioning wheel 10 is more accurate.

In order to ensure that the motor can rotate the tensioning wheel 10 to the original position every time, the embodiment selects that the included angle between the two sides of the tensioning wheel 10 is alpha, the diameter of the hole 11 of the detection area 16 is 2R, the diameter of the tensioning wheel 10 to be moved is L, and the distance of the metal strip of the detection area 16 to be moved is less than or equal to R in order to ensure that the light of the infrared sensor 19 can pass through the hole 11
