[0002] The traditional punching is to use the specially-made mould, and to exert certain pressure on the part to be processed, so as to punch various shapes of through holes on the part to be processed. The traditional punching equipment includes mechanical punching machine, pneumatic punching machine, hydraulic punching machine and the like. The above-mentioned punching machines adopt the principle of cold working, the part to be processed is placed between the upper die sleeve and the lower die sleeve, the upper die sleeve and the lower die sleeve are mutually misaligned, and a large shearing force is exerted on the part to be processed, so as to cut out the hole.

[0003] The patent document with the publication number CN207789149U discloses a punching positioning device for a sponge punching machine. In the using process of the device, the user places the sponge on the surface of the positioning plate and makes the sponge be clamped at the inside lateral beam of the positioning plate to ensure the front and back direction position of the sponge, then opens the control switch to control the lateral positioner, the piston rod moves in the piston of the auxiliary cylinder to drive the clamping plate to push forward, the left and right sides act simultaneously to ensure that the sponge is in the middle position in the left and right directions, then the piston rod resets, the clamping plate is collected on the two sides inside, and the sponge punching is avoided from being affected, then the main cylinder is controlled to make the punching plate and the blanking plate press downward, the punch pierces through the sponge to act on the surface of the positioning plate, the reset spring is compressed, the punching plate and the blanking plate are collected, and the main cylinder is upward, the blanking plate resets under the action of the reset spring, the sponge is driven to fall downward, and the sponge is convenient to take. However, due to the special elasticity and flexibility of the sponge, problems such as the hole not being punched or the hole size being inaccurate are prone to occur.

[0004] The ultrasonic wave is a wave form, the ultrasonic wave can generate high-frequency vibration, the high-frequency vibration of the ultrasonic punching head is transmitted to the punching head, the high-frequency vibration of the punching head cuts into the micro area high-speed friction between the punching head and the processed material, so that a very smooth cutting section is obtained. The friction between the high-frequency vibration of the punching head and the processed material also generates heat, so that the burr or burr of the processed material can be prevented during the cutting process.

[0005] The patent document with the publication number CN205650670U discloses an ultrasonic punching device and ultrasonic punching equipment. After being close enough to the part to be processed, the ultrasonic transducer starts, the high-frequency vibration of the ultrasonic punching head makes the surface of the part to be processed generate a large amount of heat, so as to melt the part to be processed layer by layer; at the same time, the cylinder slowly advances, the ultrasonic punching head slowly inserts into the part to be processed, until a through hole is generated. The hole punched by the ultrasonic punching device has low roughness, accurate size and no internal stress, which meets the production needs of high standards. At the same time, a blowing pipeline is arranged, after punching once or several times, the blowing pipeline is connected to the gas source and blows air, so that the waste is blown down, and automatic cleaning is realized.

[0006] In the punching process, the device needs to blow out the waste after each punching, and in the continuous punching process, the blown waste is easy to fall on the processing material, causing the thickness of the processing material to increase, and causing the excess material generated after punching to be unable to be effectively separated, and causing the excess material to be easily stuck. Practical new type content

DETAILED DESCRIPTION

[0025] The technical scheme in the embodiments of the present utility model will be described clearly and completely below in combination with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only part of the embodiments of the present utility model, not all the embodiments.

[0026] Embodiment one: refer to Figures 1-4 The novel sponge punching machine shown in the drawing, including lower plate 3, lower plate 3 top fixed plate 1, specific, the top plate 1 and lower plate 3 are fixedly connected through two side plates 2, two side plates 2 are symmetrically arranged left and right.

[0027] A lifting plate 7 is arranged to slide in the vertical direction between the top plate 1 and the lower plate 3, and the lifting plate 7 is connected to the top plate 1 by a driving device. Specifically, the driving device comprises a plurality of vertically arranged upper telescopic rods 6, and the lifting plate 7 is connected to the top plate 1 by the plurality of upper telescopic rods 6.

[0028] An ultrasonic transducer 8 is fixed to the upper end of the lifting plate 7, and a plurality of punching pipes 18 are fixed to the lower end of the lifting plate 7, and circular knife edges are formed at the lower end of the punching pipes 18.

[0029] When punching the sponge, the sponge is placed on the upper end of the lower plate 3, and then the ultrasonic transducer 8 is electrically connected to the ultrasonic generator. After starting the ultrasonic generator, the ultrasonic transducer 8 makes the punching pipe 18 vibrate at high frequency. The upper telescopic rod 6 is started, so that the lifting plate 7, the ultrasonic transducer 8 and the punching pipe 18 go down, and the high-frequency vibrating punching pipe 18 can cut the sponge after being extruded with the sponge. The cuttings enter the punching pipe 18. After the sponge is punched, the upper telescopic rod 6 drives the lifting plate 7, the ultrasonic transducer 8 and the punching pipe 18 to go up, and the ultrasonic generator is turned off when the lifting plate 7, the ultrasonic transducer 8 and the punching pipe 18 go up.

[0030] A longitudinal through hole 16 is formed in the lifting plate 7 above each column of punching pipes 18, and the through hole 16 is in communication with the punching pipe 18 below it. Specifically, the through hole 16 is in communication with the punching pipe 18 below it through the opening 17 formed at the lower end of the lifting plate 7.

[0031] A bellows 11 is arranged on the front side of the lifting plate 7, and the bellows 11 is fixed to the front end of the side plate 2. The bellows 11 is open at the rear end, the bellows 11 is in communication with the air source, and when the lifting plate 7 goes down and is located directly behind the bellows 11, the bellows 11 is in communication with the through hole 16 in the lifting plate 7. Specifically, the air source comprises a fan 9, and the air outlet of the fan 9 is in communication with the bellows 11 through the air pipe 10.

[0032] During continuous punching, the cuttings enter the punching pipe 18 in sequence, and as the number of cuttings in the punching pipe 18 increases, the cuttings continuously go up in the punching pipe 18, and the cuttings in the punching pipe 18 will continuously enter the through hole 16 through the opening 17.

[0033] When there are many cuttings in the through hole 16, the fan 9 is started, and the fan 9 sends air to the bellows 11 through the air pipe 10. When the bellows 11 is in communication with the through hole 16 during the subsequent punching of the sponge by the lifting plate 7, the air entering the through hole 16 blows the cuttings in the through hole 16 out. The bellows 11 is in communication with the through hole 16 when the lifting plate 7 goes down to punch the sponge, which can avoid the air in the through hole 16 entering the punching pipe 18 and blowing the cuttings in it out and falling on the sponge.

[0034] Example two: on the basis of example one, referring to Figures 1-4As shown, the lower plate 3 is provided with a slot hole 5 concentric with the punching pipe 18, and the diameter of the slot hole 5 is smaller than the outer diameter of the punching pipe 18. The lower end of the bottom plate is fixed with a plurality of supporting rods 4, the supporting rods 4 are slidingly connected with the connecting plate 12, the connecting plate 12 is connected with the lower plate 3 through a plurality of vertical lower extension rods 15, the connecting plate 12 is fixed with a vertical rod 13 concentric with the punching pipe 18, and the upper end of the vertical rod 13 is fixed with a brush head 14.

[0035] In the process of continuously punching the sponge, when the punching frequency is high, the temperature of the punching pipe 18 rises, and the excess material in the punching pipe 18 is easy to be bonded with the punching pipe 18. After the temperature of the punching pipe 18 rises, the punching diameter on the sponge increases, at which time the machine should be stopped to cool the punching pipe 18.

[0036] After the punching pipe 18 is cooled, the excess material bonded in the punching pipe 18 is not convenient to discharge.

[0037] In the embodiment, the lower extension rod 15 is started to drive the connecting plate 12 to drive the vertical rod 13 and the brush head 14 to go up. After the brush head 14 and the vertical rod 13 penetrate through the slot hole 5, they enter the punching pipe 18, and then the inner wall of the punching pipe 18 is cleaned by the brush head 14 to push out the excess material bonded in the punching pipe 18. The excess material bonded in the punching pipe 18 cannot effectively go up in the punching pipe 18 in the subsequent sponge punching process.

[0038] The above only describes the preferred embodiments of the present application, and does not limit the present application, and any modification, equivalent replacement and improvement made within the spirit and principle of the present application should be included in the protection scope of the present application.
