Description

Technical Field

[0001] The utility model belongs to the technical field of drum paper production, and in particular relates to a punching device for drum paper production. Background Art

[0002] The drum paper is the main sound-generating component of the horn. The sound quality of the horn is closely related to the drum paper. The drum paper has an important parameter FO value, that is, the vibration frequency value of the drum paper. The higher the FO value, the higher the range of the drum paper, and vice versa. For example, the FO value of the drum paper of the car horn is generally not higher than 100, and its sound is very low. When the drum paper of the car horn is produced, it needs to be placed on the forming mold for stamping and forming of the shape. This process is generally operated by stamping and forming equipment.

[0003] In the existing small-scale production projects, when producing drum paper, the stamping equipment uses a single cylinder to drive the punch head to press down in order to reduce the investment cost. This process requires manual placement of the drum paper on the lower die seat. Since workers may make mistakes in operation, the servo cylinder is easy to squeeze the workers' hands during the pressing process, which poses certain safety hazards. For this reason, an improved stamping equipment for drum paper production was designed. Utility Model Content

[0004] In view of the above-mentioned deficiencies existing in the prior art, the utility model provides a punching device for drum paper production to solve the above-mentioned problems in the background technology.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A stamping device for producing drum paper comprises a base plate, a gantry mounted on the base plate, and an equipment box, wherein a cylinder is mounted on the top of the gantry, a mounting plate is connected to the movable end of the cylinder, an upper die for stamping drum paper is mounted on the bottom of the mounting plate, a lower die seat for placing drum paper is arranged below the upper die, a first start key and a second start key are mounted on the base plate, the start keys are electrically connected to a controller in the equipment box, and a time delay relay is arranged on the circuit between the controller and the cylinder.

[0007] By adopting the above-mentioned structural design, the stamping equipment for drum paper production includes a base plate and a gantry and an equipment box installed on the base plate, a cylinder is installed on the top of the gantry, the movable end of the cylinder is connected to the mounting plate, an upper mold for stamping drum paper is installed at the bottom of the mounting plate, a lower mold base for placing drum paper is arranged below the upper mold, a first start key and a second start key are installed on the base plate, the start key is electrically connected to the controller in the equipment box, a delay relay is arranged on the circuit between the controller and the cylinder, when in use, the drum paper is placed on the lower mold base, and the first start key and the second start key are pressed by both hands at the same time, at which time the controller controls the cylinder to move downward, and the drum paper is turned on and off. The over-delay relay controls the closing time of the upper mold and the lower mold base, that is, the time for the mold to be pressed. In particular, as long as one hand releases the start button, the cylinder will retract. Only when both hands press the start button will the upper mold and the lower mold base close. The reason for this design is that when the operator places the drum paper, the position may be misplaced. The operator will unconsciously make an action to straighten the product with his hands. This situation is more dangerous and may cause the operator's hands to be crushed. For this reason, the improved design requires both hands to press the start button at the same time, and the upper mold will move down and close and press with the lower mold base to avoid the situation where a single-handed operator's hand is crushed.

[0008] Furthermore, the equipment box is installed beside the gantry, the delay relay is installed in the equipment box, the first start button and the second start button are arranged on the left and right sides in front of the gantry, and also includes a power switch for controlling the operation of the entire equipment.

[0009] Furthermore, a slide rail is installed on the inner side wall of the gantry along its height direction, a slider is slidably connected to the slide rail, and the slider is fixedly connected to the mounting plate.

[0010] Furthermore, a connecting head is provided at the movable end of the cylinder, and the connecting head is fixedly connected to the upper surface of the mounting plate.

[0011] Furthermore, two rod sleeves are provided on the top plate of the gantry, and the two rod sleeves are symmetrically arranged on the left and right sides of the cylinder, and a guide rod is movably arranged inside the rod sleeve, and the guide rod is fixedly connected to the mounting plate. By adopting the above structural design, the stamping equipment for drum paper production increases the stability of the upper mold movement by adding a slide rail, a slider and a guide rod.

[0012] Furthermore, the number of the upper mold and the number of the lower mold base are both two. By adopting the above structural design, the punching equipment for drum paper production includes a bottom plate with two upper molds and a lower mold base, which can improve the processing efficiency of the equipment.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. The punching equipment for drum paper production includes a base plate, a gantry and an equipment box installed on the base plate, a cylinder is installed on the top of the gantry, a mounting plate is connected to the movable end of the cylinder, an upper mold for punching drum paper is installed at the bottom of the mounting plate, a lower mold base for placing drum paper is arranged below the upper mold, a first start key and a second start key are installed on the base plate, the start key is electrically connected to the controller in the equipment box, a delay relay is arranged on the circuit between the controller and the cylinder, when in use, the drum paper is placed on the lower mold base, and the first start key and the second start key are pressed by both hands at the same time, at this time, the controller controls the cylinder to move downward, and the delay relay is used to start the drum paper. Control the time for the upper mold and the lower mold base to press together. In particular, as long as one hand releases the start button, the cylinder will retract. Only when both hands press the start button will the upper mold and the lower mold base close together. The reason for this design is that when the operator places the drum paper, it may be placed in an offset position. The operator will unconsciously make an action to straighten the product with his hands. This situation is more dangerous and may cause the operator's hands to be crushed. For this reason, the improved design requires both hands to press the start button at the same time, and the upper mold will move down and close with the lower mold base to avoid the situation where the single-handed operator is crushed, thereby improving the safety of the equipment.

[0027] Embodiment 1:

[0028] like Figure 1-4Specifically, a punching device for drum paper production includes a bottom plate 1, a gantry 2 and an equipment box 3 installed on the bottom plate 1, a cylinder 4 is installed on the top of the gantry 2, a mounting plate 6 is connected to the movable end of the cylinder 4, an upper mold 7 for punching drum paper is installed at the bottom of the mounting plate 6, a lower mold base 8 for placing drum paper is arranged below the upper mold 7, a first start key 12 and a second start key 13 are installed on the bottom plate 1, the start key is electrically connected to the controller in the equipment box 3, and a delay relay is arranged on the circuit between the controller and the cylinder 4. By adopting the above structural design, the punching equipment for drum paper production includes a base plate 1 and a gantry 2 and an equipment box 3 installed on the base plate 1. A cylinder 4 is installed on the top of the gantry 2, and a mounting plate 6 is connected to the movable end of the cylinder 4. An upper mold 7 for punching drum paper is installed at the bottom of the mounting plate 6. A lower mold base 8 for placing drum paper is arranged below the upper mold 7. A first start key 12 and a second start key 13 are installed on the base plate 1. The start key is electrically connected to the controller in the equipment box 3. A delay relay is arranged on the circuit between the controller and the cylinder 4. When in use, the drum paper is placed on the lower mold base 8, and the first start key 12 and the second start key 13 are pressed by both hands at the same time. The controller controls the cylinder 4 to move down, and controls the time for the upper mold 7 and the lower mold base 8 to press together through the delay relay. In particular, as long as one hand releases the start button, the cylinder 4 will retract. Only when both hands press the start button will the upper mold 7 and the lower mold base 8 close together. The reason for this design is that when the operator places the drum paper, there may be a situation where the position is not placed properly. The operator will unconsciously produce an action to use his hand to straighten the product. This situation is more dangerous and may cause the operator's hand to be crushed. For this reason, the improved design requires both hands to press the start button at the same time, and the upper mold 7 will move down and close and press with the lower mold base 8 to avoid the situation where the single-handed operator is crushed. Combined with the actual time delay relay, the time can be set to 0.3 seconds, that is, the pressing time of the upper mold 7 and the lower mold base 8. After the stamping is completed, release the start button, the cylinder 4 retracts and drives the upper mold 7 to rise. The staff removes the stamped drum paper and re-places the new drum paper to repeat the drum paper stamping work, thereby improving the practical safety of the equipment.

[0029] In this embodiment, the equipment box 3 is installed beside the gantry 2, the delay relay is installed in the equipment box 3, the first start button 12 and the second start button 13 are arranged on the left and right sides in front of the gantry 2, and also includes a power switch 14 for controlling the operation of the entire equipment.

[0030] In this embodiment, a slide rail 10 is installed on the inner side wall of the gantry 2 along its height direction, a slider 11 is slidably connected to the slide rail 10, and the slider 11 is fixedly connected to the mounting plate 6. A connector 5 is provided at the movable end of the cylinder 4, and the connector 5 is fixedly connected to the upper surface of the mounting plate 6.

[0031] In this embodiment, two rod sleeves 21 are provided on the top plate of the gantry 2, and the two rod sleeves 21 are symmetrically arranged on the left and right sides of the cylinder 4. A guide rod 9 is movably arranged inside the rod sleeve 21, and the guide rod 9 is fixedly connected to the mounting plate 6. By adopting the above structural design, the stamping equipment for drum paper production increases the stability of the movement of the upper mold 7 by adding the slide rail 10, the slider 11 and the guide rod 9.

[0032] In this embodiment, there are two upper molds 7 and two lower mold bases 8. By adopting the above structural design, the punching equipment for drum paper production includes a bottom plate 1 with two upper molds 7 and two lower mold bases 8, which can improve the processing efficiency of the equipment.

[0033] Working principle: When in use, place the drum paper on the lower die seat 8, and press the first start button 12 and the second start button 13 with both hands at the same time. At this time, the controller controls the cylinder 4 to move down, and controls the time for the upper mold 7 and the lower die seat 8 to close through the delay relay, that is, the time for the mold to be pressed. In particular, as long as one hand releases the start button, the cylinder 4 will retract. Only when both hands press the start button will the upper mold 7 and the lower die seat 8 close. The reason for this design is that when the operator places the drum paper, there may be a situation where the position is not placed properly. The operator will unconsciously produce an action to use his hands to straighten the product. This situation is more dangerous and may cause the operator's hand to be crushed. For this reason, the improved design requires both hands to press the start button at the same time, and the upper mold 7 will move down and close and press with the lower die seat 8 to avoid the situation where the single-handed operator is crushed. Combined with the actual time of the delay relay, the time can be set to 0.3 seconds, that is, the pressing time of the upper mold 7 and the lower die seat 8. After the stamping is completed, the start button is released, the cylinder 4 retracts to drive the upper mold 7 to rise, and the staff removes the drum paper after stamping and replaces the new drum paper to perform repeated cycles of drum paper stamping, thereby improving the practical safety of the equipment.
