Through the punching machine, some alloy materials can be processed into workpieces of specific shapes to meet different usage requirements. There are still some problems when using the existing punching machines, such as: The patent name disclosed in the prior art with the announcement number "CN118751751A" is "A stamping equipment for aluminum alloy workpieces", which discloses that the feeding mechanism includes a rotating seat fixedly installed inside one side of the base, a pulley is rotatably installed on the upper end of the rotating seat, a lifting rod is fixedly installed on the upper end of the lifting platform, and a lifting block is fixedly installed on the telescopic end of the lifting rod through the lifting platform, a rotating motor is fixedly installed on the surface of one side of the lifting block, and a driving wheel is rotatably installed on the lower end of the lifting block. The lifting block moves up and down along the inside of the lifting platform. The staff sends the raw material plate to one side of the lifting platform. When the feeding process is required, the lifting rod drives the lifting block to descend along the inside of the lifting platform, and the rotating motor fixedly installed on one side of the lifting block drives the driving wheel rotatably installed at the lower end of the lifting platform to rotate, and the plate is transported by the contact between the driving wheel and the pulley; When the stamping equipment in the above-mentioned prior art is in use, the plate is transported by the cooperation of the driving wheel and the pulley. Although self-loading is also possible, when loading some coiled alloy materials, the cooperation of the driving wheel and the pulley can only simply perform the loading work, and the bent area of ​​the alloy material cannot be straightened, so that the material cannot enter the stamping area smoothly, which will affect the subsequent stamping effect and quality.

[0003] The patent name disclosed in the prior art with the announcement number "CN113828674A" is "A stamping device for the production of aluminum-magnesium-lithium alloy materials". It discloses that a cavity is provided on the upper part of the lower mold, and a sliding head is provided through the inner walls of the left and right sides of the bottom of the cavity. The head is provided to lift the stamping part to facilitate the demoulding of the stamping part. The lower end of the head is fixedly connected to a sliding rod, and the lower ends of the sliding rods penetrate the upper wall of the base and extend to the inside of the base. The bottom ends of the two sliding rods are fixedly connected to a connecting plate, and a screw rod is fixedly provided on the bottom surface of the connecting plate. The lower end of the screw rod penetrates and extends To the bottom of the partition, a worm wheel is threadedly installed on the outer wall of the screw rod, and the worm wheel is rotatably installed on the upper surface of the partition through a worm wheel seat, a worm is meshedly connected to the worm wheel, one end of the worm is connected to a rotating shaft, and one end of the rotating shaft is rotatably installed on the upper surface of the partition through a mounting block, and the other end of the rotating shaft penetrates and extends to the outside of the base and is transmission-connected with the output shaft of a driving motor, the driving motor drives the rotating shaft to rotate, the rotating shaft drives the worm to rotate, the worm drives the worm wheel to rotate, the rotation of the worm wheel causes the screw rod to be lifted and lowered, the screw rod drives the sliding rod to lift and lower through the connecting plate, and the sliding rod drives the top head to lift the stamping part; When the stamping device in the above-mentioned prior art is in use, when the stamping part needs to be lifted and demoulded, the drive motor needs to be started first. Such a setting not only makes the production cost higher, but also makes it impossible to save energy during use, thereby increasing the cost of use.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: the self-loading follow-up demoulding mode alloy material punching machine, the feeding plates cooperate with each other to not only intermittently pull and feed the alloy material, but also extrude and clamp the alloy material through the cooperation of the two feeding plates of the rectangular structure, so as to facilitate the straightening of the bending area of ​​the alloy material, so that the alloy material enters the stamping area smoothly, thereby improving the stamping effect and quality in the later stage, and through the setting of the follow-up demoulding mechanism, the upper stamping die set rises and automatically demoulds, the structure is simple, no additional power source is required, and the production and manufacturing cost and the later use cost are saved. The specific contents are as follows: The upper and lower control rods rotate in opposite directions, which in turn makes the two sprocket assemblies rotate in opposite directions, so that when the two feeding plates move to the right, the two feeding plates clamp the alloy material and then automatically feed it to the right; when the two feeding plates move to the left, the two feeding plates will separate from the alloy material, and then the upper stamping die and the lower stamping die will cooperate to perform the stamping operation. Such repeated operations not only make the feeding plates cooperate with each other to intermittently pull and feed the alloy material, but also can extrude and clamp the alloy material through the cooperation of the two feeding plates with a rectangular structure, thereby facilitating the straightening of the bent area of ​​the alloy material, so that the alloy material enters the stamping area smoothly, thereby improving the stamping effect and quality in the later stage.

[0017] By setting the follow-up demoulding mechanism, when the electric push rod drives the upper punching die set to move upward and reset, the cross plate drives the second piston column to move upward, and the gas in the second gas storage pipe enters the second gas storage pipe, so that the first piston column automatically drives the demoulding die plate to move downward, so that the demoulding die plate drives the stamped workpiece to move downward together, and then it is convenient to automatically demould with the rise of the upper punching die set. The structure is simple, no additional power source is required, and the production and manufacturing cost and the later use cost are saved; Furthermore, by setting the self-adjusting rod, the self-adjusting rod pushes one end of the continuously descending stripping plate, thereby making the continuously descending stripping plate inclined, so that the stamped workpiece above the stripping plate can automatically slide to the left and be collected without the need for manual picking up by staff.

[0018] During the lifting process, the upper stamping die can drive the straightening plate to lift and lower reciprocate through the follow-up control component, so that the straightening plate can press the alloy material below reciprocatingly, thereby further straightening the bending area of ​​the alloy material, further improving the flatness of the alloy material entering the stamping area, and further improving the stamping effect and quality in the later stage; At the same time, through the setting of the smoothing rollers, when the straightening plate is moving downward to straighten the bent area of ​​the alloy material, the smoothing rollers on the left and right sides of the straightening plate rotate outward, so that the two groups of smoothing rollers cooperate to apply a thrust to the bent area of ​​the alloy material to push and smooth it to both sides, thereby assisting the straightening plate to perform the straightening operation well; Through the adsorption of the first adsorption block and the second adsorption block set with opposite magnetic poles, the two groups of smoothing rollers will not rotate in the opposite direction when the straightening plate rises, and exert an inward thrust on the bending area of ​​the alloy material. When the straightening plate rises to a certain height, a thrust is exerted on the mounting frame through the fixed fixing plate, so that the mounting frame drives the smoothing rollers to reset for the next use.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] See also Figure 1-Figure 11 , the present invention provides the following technical solutions: Embodiment 1: The self-loading follow-up stripping mode alloy material punching machine in this embodiment can not only self-load the alloy material when in use, but also make the alloy material enter the punching area smoothly, thereby improving the stamping effect and quality of the alloy material in the later stage. The specific structure is shown in the attached Figure 1-Figure 5As shown, it includes an outer frame 1 and a feeding frame 2 installed on the left side of the outer frame 1; two groups of limit rollers 3 are symmetrically installed inside the left and right sides of the feeding frame 2, and each group is provided with two; the inside of the feeding frame 2 is connected to a feeding plate 10 for intermittent pulling and self-feeding of alloy materials through a displacement control mechanism; an electric push rod 4 is installed inside the upper part of the outer frame 1, and the lower part of the electric push rod 4 is connected to an upper stamping die set 6 through a cross plate 5; a lower stamping die set 7 is installed on the outer frame 1 below the upper stamping die set 6, and a stripping plate 9 is connected to the outer frame 1 below the lower stamping die set 7 through a follow-up stripping mechanism, and the displacement control mechanism includes upper and lower groups of control rods 13 installed through the slots on the inner wall of the rear side surface of the feeding frame 2, each The outer sides of the two control rods 13 in the group are connected through a sprocket assembly 14; an extension rod 141 is installed on the front side of the chain in the sprocket assembly 14, and a loading plate 10 is rotatably installed on the front end of the extension rod 141; transmission gears 131 are installed on the outer sides of the rear ends of the upper and lower control rods 13 on the far right, and the two transmission gears 131 are meshed and connected. The rotation directions of the upper and lower control rods 13 on the far right are opposite, and the inner walls of the upper and lower side surfaces of the loading frame 2 are grooved and installed with sliding rods 11, and a manual telescopic rod 12 is slidably connected to the outer side of the sliding rod 11, and one end of the manual telescopic rod 12 is connected to the outer side of the loading plate 10; the shortest spacing between the two loading plates 10 is smaller than the shortest spacing between the two limiting rollers 3.

[0023] First, place the rolled alloy material on the external material discharging rack, then insert one end of the rolled alloy material between the two limit rollers 3 for loading, then connect the rear end of the lower control rod 13 to the external motor, the motor drives the lower control rod 13 to rotate clockwise, the lower control rod 13 drives the sprocket assembly 14 to rotate clockwise during rotation, and then the sprocket assembly 14 drives the lower loading plate 10 to move upward and then to the right through the extension rod 141, at this time, the manual telescopic rod 12 on the lower surface of the lower loading plate 10 is stretched, and then the manual telescopic rod 12 slides on the outside of the lower slide bar 11, thereby ensuring that the lower loading plate 10 stably moves upward and then to the right, and at the same time When the control rod 13 at the bottom rotates clockwise, the two sets of meshing transmission gears 131 at the outer side of the rear end drive the control rod 13 at the top to rotate counterclockwise. When the control rod 13 at the top rotates counterclockwise, the sprocket assembly 14 is driven to rotate counterclockwise. Then the sprocket assembly 14 drives the upper feeding plate 10 to move downward and then to the right through the extension rod 141. At this time, the manual telescopic rod 12 on the upper surface of the upper feeding plate 10 is stretched, and then the manual telescopic rod 12 slides on the outer side of the upper sliding rod 11, thereby ensuring that the upper feeding plate 10 moves downward and then to the right stably. Therefore, the upper and lower feeding plates 10 clamp one end of the rolled alloy material and then pull the material to the right. When the upper and lower loading plates 10 move to the rightmost side, as shown above, the upper loading plate 10 will first move upward and then move to the left, and the lower loading plate 10 will first move downward and then move to the left, thereby separating the two loading plates 10 from one end of the alloy material and no longer clamping one end of the alloy material. Then, when the upper and lower loading plates 10 move to the leftmost side, the upper loading plate 10 will first move downward and then move to the right, and the lower loading plate 10 will first move upward and then move to the right, so that the two loading plates 10 cooperate to clamp one end of the alloy material and pull it to the right to load the material. This operation is repeated so that the two loading plates 10 cooperate intermittently. One end of the alloy material is pulled for feeding, which not only performs self-feeding well, but also performs extrusion pressing on the alloy material through the cooperation of two rectangular feeding plates 10, so that the bent area of ​​the alloy material can be straightened, so that the alloy material can enter the stamping area smoothly, and then when the feeding plate 10 moves to the left, the alloy material stops feeding, and the electric push rod 4 is started at this time. The output end of the electric push rod 4 drives the cross plate 5 and the upper stamping die 6 to move downward, and then the upper stamping die 6 stamps the alloy material on the lower stamping die 7 into a workpiece of a certain shape, and then the stamped workpiece falls onto the stripping plate 9.

[0024] Embodiment 2: The self-loading follow-up demoulding model alloy material punching machine in this embodiment can automatically demould the formed workpiece through the follow-up demoulding mechanism when in use, without the need for an additional power source, thus saving energy and reducing production costs. For specific structure, please refer to the attached Figure 9-11 As shown, on the basis of the first embodiment, the follow-up demoulding mechanism includes a second piston column 25 installed on the rear side of the horizontal plate 5, and the second piston column 25 is arranged in the groove of the outer frame 1 in a "7"-shaped structure; a second gas storage pipe 26 is installed inside the outer frame 1 on the rear side of the lower punching die 7, and the second piston column 25 is fitted and connected to the upper interior of the second gas storage pipe 26; a first gas storage pipe 22 is installed in the outer frame 1 below the lower punching die 7, and the first piston column 23 is fitted and connected to the upper interior of the first gas storage pipe 22, and a support with a "U"-shaped structure is installed on the upper end of the first piston column 23. The support frame 20 is provided with a stripper plate 9 on the inner side through a mounting rod 28, and a third vortex spring 27 is nested and connected to the outer side of the mounting rod 28. A lower punching die set 7 is provided above the stripper plate 9, and there is a gap between the upper surface of the stripper plate 9 and the lower surface of the lower punching die set 7. The lower interior of the second gas storage pipe 26 is connected to the lower interior of the first gas storage pipe 22 through an air supply pipe 24. A self-adjusting rod 21 is installed in a groove in the outer frame 1 below the lower punching die set 7, and a stripper plate 9 is provided above the self-adjusting rod 21. The stripper plate 9 forms a rotating structure through the self-adjusting rod 21.

[0025] When the output end of the electric push rod 4 drives the cross plate 5 and the upper stamping die set 6 to move downward, the cross plate 5 drives the second piston column 25 installed on the rear side to move downward together, and then the second piston column 25 pushes part of the gas in the second gas storage pipe 26 into the first gas storage pipe 22 through the gas supply pipe 24. At this time, the gas in the first gas storage pipe 22 automatically drives the internal first piston column 23 to move upward. At this time, the first piston column 23 drives the support frame 20 and the stripping plate 9 to move upward. When the stripping plate 9 moves to separate from the upper end of the self-adjusting rod 21, the third vortex spring 27 automatically drives the mounting rod 28 to rotate in the opposite direction and reset. At this time, the mounting rod 28 drives the stripping plate 9 to rotate horizontally. At this time, when the upper stamping die set 6 cooperates with the lower stamping die set 7 to perform stamping operations, the stamped workpiece will fall on the stripping plate 9. At this time, the stamped workpiece is separated from the lower stamping die 7.

[0026] Then, when the upper stamping die 6 moves upward, as shown above, the cross plate 5 drives the second piston column 25 to move upward. At this time, the gas in the first gas storage pipe 22 enters the second gas storage pipe 26 through the gas pipe 24, and then the first piston column 23 drives the support frame 20 and the stripping plate 9 to move downward. When the stripping plate 9 moves downward, the fixed self-adjusting rod 21 will apply a thrust to the right side of the stripping plate 9, so that the stripping plate 9 rotates in an inclined shape with the mounting rod 28 as the center. At this time, the formed workpiece on the inclined stripping plate 9 will automatically slide to the left, which is convenient for follow-up demolding and collection of the workpiece on the stripping plate 9.

[0027] Embodiment 3: The self-loading follow-up mode alloy material punching machine in this embodiment, on the basis of embodiment 1, can further make the alloy material enter the punching area smoothly, thereby further improving the stamping effect and quality of the alloy material in the later stage. The specific structure is shown in the attached Figure 6-Figure 8As shown, a vertical rod 101 is installed in a groove on the front side of the outer frame 1 on the left side of the upper stamping die 6, and a straightening plate 8 is slidably connected to the outer side of the vertical rod 101, and a connecting spring 102 is nested and connected to the lower outer side of the vertical rod 101, and a follow-up regulating component is arranged above the straightening plate 8, and the straightening plate 8 forms a reciprocating lifting structure with the outer frame 1 through the follow-up regulating component, and the follow-up regulating component includes a cross bar 15 installed on the front side of the outer frame 1, and the cross bar 15 is arranged above the straightening plate 8, and the rear end of the cross bar 15 is nested and connected with a first vortex spring 153, and three groups of push plates 152 are installed at equal intervals on the outer side of the cross bar 15, and each group is provided with two, and the length of the push plate 152 is greater than the shortest distance between the straightening plate 8 and the cross bar 15 A connecting rope 151 is wound around the outer side of the middle part of the cross bar 15, and the upper part of the connecting rope 151 is connected to the cross plate 5 through a guide wheel. The left and right sides of the straightening plate 8 are grooved with a rotating rod 19, and a mounting frame 18 is installed on the outer side of the rotating rod 19. A smoothing roller 17 is installed below the mounting frame 18. A second vortex spring 191 is nested and connected to the outer side of the front end of the rotating rod 19, and a second adsorption block 181 is installed on the outer side of the mounting frame 18. The first adsorption blocks 81 are installed in the grooves on the left and right sides of the straightening plate 8. The second adsorption block 181 and the first adsorption block 81 are made of magnet blocks with opposite poles. Two fixed plates 16 are symmetrically installed on the front side of the outer frame 1, and a mounting frame 18 is provided below the fixed plate 16.

[0028] When the cross plate 5 and the upper stamping die 6 move downward, the cross plate 5 will pull the connecting rope 151 on the left, and the left end of the connecting rope 151 will drive the cross bar 15 to rotate. At this time, the first vortex spring 153 on the rear side of the cross bar 15 accumulates force, and the cross bar 15 will drive the three groups of push plates 152 arranged at equal intervals to apply a downward thrust to the straightening plate 8 in turn when rotating. At this time, the rear side of the straightening plate 8 slides downward on the outside of the vertical rod 101, and the connecting spring 102 is squeezed and accumulated. Then the straightening plate 8 presses the alloy material on the lower stamping die 7 up and down reciprocatingly, thereby further straightening the alloy material.

[0029] At the same time, when the straightening plate 8 moves downward, the smoothing rollers 17 on the left and right sides of the straightening plate 8 first contact with the alloy material. Then, when the straightening plate 8 continues to move downward, the smoothing rollers 17 on the left and right sides of the straightening plate 8 will rotate outward with the rotating rod 19 as the center. At this time, the second vortex spring 191 accumulates force, and the smoothing roller 17 will apply an outward smoothing thrust to the alloy material during the outward rotation process, so as to further smooth the alloy material, so that the straightening plate 8 can press the alloy material well in the later stage. When the smoothing roller 17 rotates to a certain position, the second adsorption block 181 on the outside of the mounting frame 18 is The first adsorption block 81 adsorbs, so that after the straightening plate 8 rises, the smoothing roller 17 does not rotate in the opposite direction and reset through the stored force of the second vortex spring 191. Therefore, when the straightening plate 8 rises, the smoothing roller 17 is directly separated from the alloy material. Then, when the straightening plate 8 rises to a certain height, the fixed plate 16 will apply a downward thrust to the mounting frame 18, thereby separating the second adsorption block 181 from the first adsorption block 81. At this time, the stored force of the second vortex spring 191 can make the smoothing roller 17 rotate in the opposite direction and reset, so that it can be used next time, thereby completing a series of tasks.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
