Description

Technical Field

[0001] The invention relates to the field of aluminum plate processing, and in particular to an aluminum plate fixed-length fast shearing device. Background Art

[0002] A Chinese patent application with patent number CN117564347A discloses a shearing device for aluminum plate processing, which allows the aluminum plate to be pulled out between a pressure block and a support block, and can play a role in leveling the sheared portion of the aluminum plate, making the sheared portion of the aluminum plate more flat. The reason why the sheared portion of the aluminum plate is warped is that the existing aluminum plate shearing equipment shears the aluminum plate by moving the shear knife downward in conjunction with the workbench. The sheared portion of the aluminum plate is subjected to unilateral force, resulting in warping along the moving direction of the shear knife. The above-mentioned device cannot fundamentally solve the warping problem. After the shearing is completed, the aluminum plate is squeezed and leveled by the pressure block and the support block, which will cause scratches on the surface of the aluminum plate, affecting the quality of the aluminum plate.

The I-shaped slide groove is protected by the telescopic membrane to prevent debris generated by cutting from entering the fixed rod 202; the two mounting sleeves 203 near the end of the fixed rod 202 are slidably connected to the fixed rod 202; the mounting sleeve 203 in the middle of the fixed rod 202 is fixedly connected to the fixed rod 202; the two mounting sleeves 203 near the end of the fixed rod 202 are each fixedly connected to a sliding column 303.

[0040] The shear plate 204 is composed of a shear ring 204a and a mounting plate 204b; the mounting plate 204b is fixedly connected to the mounting sleeve 203; the mounting plate 204b is sleeved with a shear ring 204a composed of two semicircular rings, and the two semicircular rings are bolted to the mounting sleeve 203 through a connecting block.

[0041] During operation, according to the size of the aluminum plate 001 to be cut, the receiving frame 102 is driven to move by starting the translation mechanism 101, and the spacing between the two receiving frames 102 in the limiting assembly is adjusted. By controlling the extension of the electric push rod 104, the spacing between the two limiting plates 103 of the receiving frame 102 is adjusted, so that the limiting assembly adapts to the size of the aluminum plate 001, thereby adapting to aluminum plates 001 of different sizes and enhancing the adaptability of the device. Then, according to the width of the cutting, the spacing of the shearing disk 204 on the fixed rod 202 is adjusted, and the driving motor 301 is started by controlling the output shaft of the driving motor 301 to drive the bidirectional screw rod 302 to rotate, so that the two sliding columns 303 on the bidirectional screw rod 302 move away from or close to each other, so that the sliding column 303 brings The movable installation sleeve 203 moves, and then the installation sleeve 203 drives the corresponding shearing disk 204 to move, and then the intervals between the three shearing disks 204 on the fixed rod 202 are adjusted. When the intervals of the shearing disks 204 are adjusted, the shearing disks 204 on the upper and lower fixed rods 202 are adjusted synchronously, and then the two aluminum plates 001 are placed on the two limiting components respectively, and the aluminum plates 001 are limited by the cooperation of the receiving frame 102 and the limiting plate 103, so that the external conveying equipment can convey and load the materials, and the non-cutting area of ​​the aluminum plate 001 is clamped by the external clamping equipment, and the clamping position and the shearing disk 204 are spaced apart from each other, and then the driving mechanism 2 is controlled to start, and the driving mechanism 2 drives the installation plate 201, the fixed rod 202, the installation sleeve 203 and The shearing disc 204 moves to the right, and then the toothed plate 206 drives the transmission gear 205 to drive the fixed rod 202 to rotate. Based on the view from the front to the back, the upper fixed rod 202 drives the corresponding shearing disc 204 to rotate clockwise, and the lower fixed rod 202 drives the corresponding shearing disc 204 to rotate counterclockwise. The two adjacent shearing discs 204 above and below are a group, and then the aluminum plate 001 is cut by three groups of upper and lower shearing discs 204 rotating in opposite directions, so that the upper and lower sides of the aluminum plate 001 are stressed at the same time, avoiding the problem of warping of the shearing edge of the aluminum plate 001, and at the same time, the aluminum plate 001 is cut into four pieces at one time to achieve fast cutting. Before the shearing disc 204 contacts the aluminum plate 001, the right electric push rod 105 contracts to make the brush rod 106 tilted The brush rod 106 moves upward so that the bristles of the brush rod 106 support the lower side of the aluminum plate 001, so that the aluminum plate 001 is in a horizontal state near the shearing disk 204, so as to prevent the aluminum plate 001 from being dented due to its own weight and causing errors in the size after cutting. When the mounting plate 201, the fixing rod 202, the mounting sleeve 203 and the shearing disk 204 move to the right, the electric push rod 105 and the brush rod 106 move to the right synchronously, so that the position of the shearing disk 204 cutting the aluminum plate 001 always remains in a horizontal state. As the aluminum plate 001 is cut into strips, the brush rod 106 on the left is in an initial state at this time, and the height of the brush rod 106 on the left is lower than the height of the lower side of the aluminum plate 001. The aluminum sheet cut into strips is received by the brush rod 106 on the left.To prevent the aluminum strip from being scratched by the shearing disc 204 after sagging due to its own weight, the quality of the aluminum strip after cutting is ensured. After cutting, the driving mechanism 2 is controlled to move in the opposite direction and reset. Another aluminum plate 001 is cut in the same way. At the same time, the aluminum plate 001 that has been cut is taken out of the limit assembly and the next aluminum plate 001 is loaded. The aluminum plate 001 is cut repeatedly in this way to ensure cutting efficiency.

[0042] When the transmission gear 205 and the tooth plate 206 work together, noise is generated. The noise generated when the transmission gear 205 and the tooth plate 206 work together is reduced by providing a noise reduction box 401 and a telescopic cloth cover 402, thereby preventing the noise from affecting the working environment of the operator. During the process of the driving mechanism 2 driving the mounting plate 201 and the fixed rod 202 to move, the mounting plate 201 drives the corresponding telescopic cloth cover 402 to reciprocate and extend, so that the corresponding limit block 402a slides in the I-shaped limit groove on the noise reduction box 401, and the edge of the telescopic cloth cover 402 is limited by the limit block 402a, so that the edge of the telescopic cloth cover 402 remains in contact with the noise reduction box 401, thereby ensuring the noise reduction effect of the noise reduction box 401 and the telescopic cloth cover 402.

[0043] The transmission gear 205 and the tooth plate 206 are both consumable parts. When the transmission gear 205 and the tooth plate 206 need to be replaced, Figure 1 In the shown state, pull out the pins in the noise reduction box 401 and the tooth plate 206, pull the tooth plate 206 out of the noise reduction box 401, and then replace the tooth plate 206, then remove the connecting plate 404 from the clamping plate 403, and the connecting plate 404 simultaneously drives the arc piece 405 to move out of the noise reduction box 401 through the magnetic force, then unscrew the bolts of the fixed sleeve on the transmission gear 205, and take the flat gear out of the fixed sleeve from the position where the arc piece 405 on the noise reduction box 401 is moved out, and then replace the flat gear, which is convenient for the operator to disassemble and replace the transmission gear 205 and the tooth plate 206.

[0044] Second embodiment

[0045] On the basis of the first embodiment, according to Figure 5-7 As shown,

[0046] It also includes an oil delivery box 501 and a three-way pipe 502; each mounting plate 201 is fixedly connected with an oil delivery box 501; the oil delivery box 501 is connected with an oil inlet pipe; each mounting plate 201 and the fixed rod 202 are connected at a rotational connection with an annular groove 002; each oil delivery box 501 is connected with the corresponding annular groove 002 through a conduit; the two annular grooves 002 in the same mounting plate 201 are connected to each other through a conduit; each annular groove 002 below is connected with a three-way pipe 502; each three-way pipe 502 is connected with two nozzles; each nozzle is directly opposite to the electric slide rail of the corresponding drive mechanism 2.

[0047] The fixing plate 3 is configured as a hollow structure, and a plurality of through grooves 003 distributed in a rectangular shape are opened on the fixing plate 3; the fixing plate 3 is connected to an oil drain pipe.

[0048] During the cutting process, the bearing at the rotation connection between the fixed rod 202 and the mounting plate 201 is prone to heat and wear, which has an adverse effect on the rotation of the fixed rod 202, and further affects the cutting quality of the shear disk 204. By setting an oil delivery box 501, before starting work, the oil inlet pipe on the oil delivery box 501 is connected to the cooling oil delivery device through a telescopic hose. During operation, the cooling oil delivery device connected to the telescopic hose is started to deliver cooling oil to the oil delivery box 501, and the oil delivery box 501 introduces the cooling oil into the upper annular groove 002 through a conduit, and the cooling oil in the upper annular groove 002 is introduced into the lower annular groove 002 through a conduit, thereby cooling the bearing at the rotation connection between the fixed rod 202 and the mounting plate 201. At the same time, the cooling oil enters the inside of the bearing through the oil inlet hole on the bearing, and then lubricates the bearing at the rotation connection between the fixed rod 202 and the mounting plate 201 through the cooling oil, so as to avoid overheating of the bearing during long-term operation and affecting its service life, and at the same time reduce bearing wear to ensure smooth operation of the bearing, ensure the service life of the bearing, and thus ensure the cutting quality of the shear disk 204.

[0049] The cooling oil in the annular groove 002 below is sprayed onto the electric slide rail of the driving mechanism 2 through the nozzle on the three-way pipe 502, so that the electric slide rail of the driving mechanism 2 is lubricated by the cooling oil, ensuring the smooth operation of the driving mechanism 2, ensuring the smooth cutting work and reducing the loss of the driving mechanism 2. The cooling oil dripping on the electric slide rail flows into the fixed plate 3 through the through groove 003, and is discharged through the oil drain pipe on the fixed plate 3 for unified collection.

[0053] The cooling oil enters the bearing through the oil inlet hole on the bearing for lubrication.

Therefore, during the coordinated operation of the transmission gear 205 and the tooth plate 206, the transmission gear 205 and the tooth plate 206 are lubricated by the cooling oil, thereby reducing the wear of the transmission gear 205 and the tooth plate 206, extending the service life of the transmission gear 205 and the tooth plate 206, and fundamentally reducing the noise generated during the coordinated operation of the transmission gear 205 and the tooth plate 206.

[0054] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
