Description

Technical Field

[0001] The invention belongs to the technical field of cutting equipment, and in particular relates to a blank cutting machine for producing metal gaskets. Background Art

[0002] The metal gasket is made of three materials: imported stainless steel, high carbon steel and brass, which are heat treated and finely ground. It has the characteristics of high precision, strong tensile strength, good finish, toughness and not easy to break. The high carbon steel has a certain elasticity. The stainless steel material is very tough and not easy to break. The metal gasket is often cut from the metal gasket blank sheet by a cutting machine. Therefore, the production of metal gaskets is inseparable from the corresponding cutting machine.

[0003] When cutting metal gasket blanks, existing cutting machines often need to use two sets of linear guides, one vertical and one horizontal, to accurately cut metal gaskets of the required size, which greatly increases the manufacturing and maintenance costs of the entire cutting machine; and the existing cutting machines only use one set of laser cutting equipment to cut and process metal gaskets, and the metal gaskets are annular structures, which requires adjusting the cutting radius of the laser cutting equipment twice, thereby reducing the processing efficiency of the entire cutting machine; at the same time, after the blanks for metal gasket production are fed into the processing table of the cutting equipment, the position of the blanks needs to be adjusted manually, which increases the workload of the operators, reduces the processing efficiency of the cutting equipment, and also leads to a decrease in the utilization rate of the blanks by the cutting equipment. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the disadvantages of the above-mentioned prior art and provide a blank cutting machine for metal gasket production.

[0006] Furthermore, the conveying mechanism includes a first sliding bar, four groups of the first sliding bars are provided, and the four groups of first sliding bars are respectively located at the four corners inside the processing table, and a lifting plate is commonly sleeved on the outer sides of the four groups of the first sliding bars, electric telescopic rods are symmetrically installed on both sides of the two ends of the bottom of the processing table, and the output ends of the electric telescopic rods are fixedly connected to the bottom of the lifting plate, a plurality of groups of first strip through holes are opened on the top of the processing table, a plurality of pairs of mounting frames are installed on the top of the lifting plate, and a guide roller matched with the first strip through holes is provided at the top of each pair of mounting frames, and a power device for driving the plurality of groups of guide rollers to rotate is provided on the top of the lifting plate.

[0007] Through the above technical scheme, the four groups of electric telescopic rods are first controlled to drive the lifting plate to rise. During the process, the lifting plate slides on the four groups of first sliding rods. After the lifting plate rises to the highest position, several groups of guide rollers pass through the first strip through holes to lift the metal gasket blank on the top of the processing table. Then, the power device is controlled to drive several groups of guide rollers to rotate synchronously in the same direction, thereby completely moving the metal gasket blank to the processing table, reducing the labor intensity of the operator in pushing the metal gasket blank. After the metal gasket blank is processed, it can be moved away from the top of the processing table, so as to facilitate the subsequent replenishment of the metal gasket blank to be processed on the processing table.

[0008] Furthermore, the power device includes a drive motor, which is located at the middle position of one end of the top of the lifting plate, a rotating rod is provided at the middle position inside each pair of mounting frames, and a driving gear is installed at one end of the outer side of the rotating rod, a driven gear meshing with the driving gear is installed on the rotating shaft at one end of the guide roller, a worm gear is installed at the middle position of the outer side of the rotating rod, and a plurality of groups of worms meshing with the worm gear are installed at the output end of the drive motor.

[0009] Through the above technical solution, the driving motor is controlled to drive all the worms to rotate, and the transmission of the worm and the worm wheel is used to drive all the rotating rods to rotate synchronously in the same direction. The rotating rods drive all the guide rollers to rotate synchronously in the same direction through the transmission of the driving gear and the driven gear, so that several groups of guide rollers can drive the metal gasket blank on the top of the processing table to move stably.

[0010] Furthermore, the longitudinal moving mechanism includes a U-shaped frame, first screw rods are symmetrically arranged on both sides of the top of the processing table, and the outer threads of the first screw rods are provided with first internal thread blocks, and one end of the bottom of the processing table is provided with a first driving device that drives two groups of first screw rods to rotate, and limit frames are symmetrically sleeved on both sides of the U-shaped frame, and the two groups of limit frames are respectively fixedly connected to an adjacent group of first internal thread blocks, and limit slide grooves that cooperate with the lifting plate are symmetrically installed on both sides of the bottom of the U-shaped frame.

During the process, the two sides of the lifting plate slide in the two groups of limit slide grooves respectively. When the lifting plate is lifted or lowered, the limit slide groove will also drive the U-shaped frame to lift or lower together.

[0012] Furthermore, the first driving device includes a first servo motor located at the middle position of one end of the bottom of the processing table, one end of the two groups of the first screw rods and the output end of the first servo motor are both equipped with a first synchronous wheel, and the outer sides of the three groups of the first synchronous wheels are jointly provided with a first synchronous belt, and two groups of auxiliary synchronous wheels that cooperate with the first synchronous belt are provided at one end of the bottom of the processing table close to the first servo motor.

[0013] Through the above technical solution, the first servo motor is controlled to cooperate with the first synchronous wheel and the first synchronous belt to drive the two sets of first screws to rotate synchronously in the same direction, and the two sets of auxiliary synchronous wheels help to improve the stability of transmission between the first synchronous belt and the three sets of first synchronous wheels.

[0014] Furthermore, the lateral moving mechanism includes a crossbeam located at the top end of the U-shaped frame, a movable frame is sleeved on the outer side of the crossbeam, a second screw rod is provided at one end of the U-shaped frame, and an internal threaded tube is sleeved on the outer side of the second screw rod, the internal threaded tube is fixedly connected to the outer side of the movable frame, and a second servo motor for driving the second screw rod to rotate is installed on one side of the U-shaped frame.

[0015] Through the above technical solution, the second servo motor is controlled to drive the second screw to rotate, and the thread action is used to force the internal threaded tube to slide with the movable frame on the beam, thereby accurately adjusting the lateral position of the first cutting mechanism and the second cutting mechanism above the processing table.

[0016] Furthermore, the first cutting mechanism includes a second strip-shaped through hole located at the top of the crossbeam, a third servo motor is installed on the top of the movable frame, the output shaft of the third servo motor passes through the second strip-shaped through hole and extends to the bottom of the movable frame and is installed with a rotating disk, a connecting bearing is installed at the outer ring position of the top of the rotating disk, and the outer ring of the connecting bearing is fixedly connected to the bottom of the movable frame, a first bracket is installed at a non-center position of the bottom of the rotating disk, a first linear guide rail is arranged on the inner side of the first bracket, and a first laser cutting device is installed on the moving seat of the first linear guide rail.

[0017] Through the above technical scheme, according to the size of the metal gasket to be processed, the first linear guide rail is controlled to drive the first laser cutting device to move horizontally, and then the vertical distance between the center line of the first laser cutting device and the center line of the rotating disk is accurately adjusted, so as to control the size of the metal gasket cut by the first laser cutting device. After that, the third servo motor is controlled to drive the rotating disk to rotate clockwise for one circle. During the process, the first laser cutting device is controlled to cut the metal gasket blank in a circle. When cutting the next position of the metal gasket, the third servo motor is controlled to drive the rotating disk to rotate counterclockwise for one circle. This process is repeated to avoid line entanglement.

[0018] Furthermore, the second cutting mechanism includes a second bracket located at the bottom of the rotating disk, the second bracket is symmetrically arranged with the first bracket, a second linear guide is arranged on the inner side of the second bracket, and a second laser cutting device that cooperates with the first laser cutting device is installed on the movable seat of the second linear guide, and the center line of the first laser cutting device, the center line of the second laser cutting device and the center line of the rotating disk are in the same plane.

[0019] Through the above technical solution, after adjusting the vertical distance between the center line of the first laser cutting device and the center line of the rotating disk, the second linear guide rail is controlled to drive the second laser cutting device to move, and the vertical distance between the center line of the second laser cutting device and the center line of the rotating disk is adjusted. Then, when the third servo motor drives the rotating disk to rotate one circle, the outer circle and inner circle of the metal gasket can be cut synchronously, thereby improving the cutting processing efficiency of the entire cutting machine.

[0020] Furthermore, the centering adjustment mechanism includes four groups of bearing seats located at both ends of both sides of the processing table, the inner rings of the bearings of the two groups of bearing seats at the same end are commonly installed with a third screw rod, the outer sides of the two groups of third screw rods are commonly symmetrically threaded with a strip clamp, the same side of the two groups of third screw rods are symmetrically installed with second synchronous wheels, and the outer sides of the two groups of second synchronous wheels are commonly provided with a second synchronous belt, and one end of one side of the processing table is installed with a fourth servo motor that is transmission-connected to an adjacent group of third screw rods.

[0021] Through the above technical scheme, the fourth servo motor is controlled to cooperate with the second synchronous wheel and the second synchronous belt to drive the two sets of third screw rods to rotate synchronously, and the two sets of strip clamps are forced to approach each other by the action of the thread. As the two sets of strip clamps continue to approach each other, the metal gasket blank can be pushed to the middle position of the top of the processing table, which is convenient for the subsequent precise cutting of the metal gasket blank.

[0022] Furthermore, the limiting mechanism includes an L-shaped frame, which is provided with two groups of L-shaped frames, and the two groups of L-shaped frames are respectively fixedly connected to the same end of the two groups of strip clamps, two groups of second sliding rods are installed at the middle position of the top of the processing table near one end of the L-shaped frame, and the outer sides of the two groups of second sliding rods are jointly sleeved with an L-shaped baffle, and a third strip through hole compatible with the L-shaped baffle is opened at the middle position of the top of the processing table near one end of the L-shaped frame, and the bottom of both sides of the L-shaped baffle is symmetrically hinged with connecting plates, and the end of the connecting plate away from the L-shaped baffle is hinged to the bottom of an adjacent group of L-shaped frames, and a limiting block is installed at the bottom of the second sliding rod.

[0023] Through the above technical solution, in the process of the two groups of strip clamps approaching each other, the two groups of strip clamps drive the two groups of L-shaped frames to approach each other synchronously, and the two groups of L-shaped frames will drive the L-shaped baffles to slide upward on the two groups of second sliding rods through the connecting plates, so that the top end of the L-shaped baffle extends out from the third strip through hole, blocking the metal gasket blank from continuing to move.

[0024] The beneficial effects of the present invention are as follows: (1) The present invention uses a longitudinal moving mechanism, a transverse moving mechanism and a first cutting mechanism in coordination, uses a screw to adjust the transverse and longitudinal coordinates of the cutting device, and then uses the first cutting mechanism to accurately adjust the cutting radius and cut the metal gasket blank, which can not only reduce the manufacturing and maintenance costs of the entire cutting equipment, but also ensure the accuracy of each cutting process; (2) The present invention uses the first cutting mechanism and the second cutting mechanism in coordination, only needs to adjust the center line of the first laser cutting device and the vertical distance from the center line to the center line of the rotating disk, and then control the rotation of the first laser cutting device and the second laser cutting device.

As the two groups of strip clamps 703 continue to approach, the metal gasket blank can be pushed to the center of the top of the processing table 1 At the intermediate position, in the process of the two groups of strip clamps 703 approaching each other, the two groups of strip clamps 703 drive the two groups of L-shaped frames 801 to approach each other synchronously, and the two groups of L-shaped frames 801 will drive the L-shaped baffles 803 to slide upward on the two groups of second slide rods 802 through the connecting plates 804, so that the top ends of the L-shaped baffles 803 extend out from the third strip through holes 806, blocking the metal gasket blanks from continuing to move, thereby ensuring that the positions of the head ends of all metal gasket blanks are fixed, thereby facilitating the subsequent first laser cutting device 507 and the second laser cutting device 603 to accurately cut the metal gasket blanks.

[0033] The working principle of this embodiment is as follows: first, the blank of the metal gasket is moved to the top of the processing table 1, and then the electric telescopic rod 203 is controlled to drive the lifting plate 202 to rise until the guide roller 206 extends from the inside of the first strip through hole 204, and then the driving motor 2075 is controlled to drive all the guide rollers 206 to rotate synchronously in the same direction, and the metal gasket blank is all moved to the top of the processing table 1, and then the fourth servo motor 706 is controlled to drive the two sets of third screw rods 702 to rotate synchronously, so that the two sets of strip clamps 703 are close to each other, and the two sets of strip clamps 703 are The top of the L-shaped baffle 803 will be driven to extend from the third strip through hole 806 to block the metal gasket blank from continuing to move. At this time, the guide roller 206 is stopped from rotating and the electric telescopic rod 203 is controlled to drive all the guide rollers 206 to descend to the inside of the processing table 1. As the two groups of strip clamps 703 continue to approach, the metal gasket blank is pushed to the middle position of the top of the processing table 1. Then, the two groups of strip clamps 703 are controlled to move back to the original position, and then the first servo motor 3031 is controlled to drive the two groups of first screw rods 301 to rotate, so that the first internal thread block 3 02 drives the U-shaped frame 305 to move above the head end of the metal gasket blank, and then controls the second servo motor 405 to drive the second screw rod 403 to rotate, and moves the movable frame 402 to a side position of the crossbeam 401, and then controls the first linear guide rail 506 to drive the first laser cutting device 507 to move, and adjusts the vertical distance between the center line of the first laser cutting device 507 and the center line of the rotating disk 503, and then controls the second linear guide rail 602 to drive the second laser cutting device 603 to move, and adjusts the vertical distance between the center line of the second laser cutting device 603 and the center line of the rotating disk 5 03, and then control the third servo motor 502 to drive the rotating disk 503 to rotate clockwise for one circle. During the process, the first laser cutting device 507 and the second laser cutting device 603 are controlled to cut the metal gasket blank. After that, it is only necessary to control the longitudinal position of the U-shaped frame 305 by the first servo motor 3031 and the lateral position of the U-shaped frame 305 by the second servo motor 405, so that the first laser cutting device 507 and the second laser cutting device 603 can cut different positions of the metal gasket blank.
