Description

Technical Field

[0001] The present invention relates to the technical field of alloy material stamping, and specifically to a stamping machine for self-feeding and follow-up stripping type alloy materials. Background Technique

[0002] When processing some alloy materials, a stamping machine is required. Through the stamping machine, some alloy materials can be processed into specific-shaped workpieces to meet different usage requirements. However, there are still some problems when the existing stamping machines are in use. For example:

[0003] In the prior art, the patent with the publication number "CN118751751A" and the patent name "A stamping device for aluminum alloy workpieces" discloses that the feeding mechanism includes a rotating seat fixedly installed inside one side of the base. A pulley is rotatably installed at the upper end of the rotating seat. A lifting rod is fixedly installed at the upper end of the lifting table. The telescopic end of the lifting rod penetrates through the lifting table and is fixedly installed with a lifting block. A rotating motor is fixedly installed on one side surface of the lifting block. A driving wheel is rotatably installed at the lower end of the lifting block. The lifting block moves up and down inside the lifting table. When the staff sends the raw material plate to one side of the lifting table and needs to perform the feeding process, the lifting rod drives the lifting block to descend inside the lifting table. 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 table to rotate. The plate is conveyed by the cooperation of the driving wheel and the pulley.

[0004] When the above-mentioned stamping equipment in the prior art is in use, the plate is conveyed by the cooperation of the driving wheel and the pulley. Although self-feeding can also be carried out in this way, when feeding some coiled alloy materials, the cooperation of the driving wheel and the pulley can only simply perform the feeding work and cannot straighten the bent area of the alloy material, so that the material cannot enter the stamping area flatly, which will subsequently affect the later stamping effect and quality.

[0005] In the prior art, the patent with the publication number "CN113828674A" has the patent name of "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 die, and the left and right inner walls of the bottom of the cavity are both slidably penetrated with ejector pins. By setting the ejector pins, the stamped parts can be lifted, facilitating the demolding of the stamped parts. The lower end of the ejector pin is fixedly connected with a sliding rod, and the lower ends of the sliding rods all penetrate the upper wall of the base and extend into the base. The bottom ends of the two sliding rods are fixedly connected with a connecting plate. A lead screw is fixedly provided on the bottom surface of the connecting plate. The lower end of the lead screw penetrates and extends below the partition plate. A worm gear is threadedly installed on the outer wall of the lead screw. The worm gear is rotatably installed on the upper surface of the partition plate through a worm gear seat. A worm is meshed with the worm gear. One end of the worm is connected with a rotating shaft. One end of the rotating shaft is rotatably installed on the upper surface of the partition plate through a mounting block. The other end of the rotating shaft penetrates and extends outside the base and is drivingly connected with the output shaft of the driving motor. The driving motor drives the rotating shaft to rotate, the rotating shaft drives the worm to rotate, the worm drives the worm gear to rotate, the rotation of the worm gear causes the lead screw to rise and fall, the lead screw drives the sliding rod to rise and fall through the connecting plate, and the sliding rod drives the ejector pin to lift the stamped part;

[0006] When the above-mentioned stamping device in the prior art is in use, when it is necessary to lift and demold the stamped part, it is necessary to first start the driving motor at this time. Such a setting not only makes the production and manufacturing cost relatively high, but also makes it impossible to save energy during use, thus increasing the use cost.

[0007] Therefore, we propose a stamping machine for alloy materials with a self-feeding and follow-up demolding mode to facilitate solving the problems raised above. Summary of the Invention

[0008] The purpose of the present invention is to provide a stamping machine for alloy materials with a self-feeding and follow-up demolding mode, so as to solve the problem that the stamping equipment on the current market cannot straighten the bent area of the alloy material, which will subsequently affect the later stamping effect and quality and increase the use cost as mentioned in the above background technology.

[0009] To achieve the above purpose, the present invention provides the following technical solution: A stamping machine for alloy materials with a self-feeding and follow-up demolding mode, including an outer frame body, and a feeding frame installed on the left side of the outer frame body;

[0010] Two groups of limiting rollers are symmetrically installed on both the left and right sides inside the feeding frame, with two in each group;

[0021] Preferably, a first air storage pipe is installed inside the outer frame body below the lower stamping module. The upper part inside the first air storage pipe is in close connection with a first piston column. The upper end of the first piston column is installed with a support frame in a "U" - shaped structure. The inner side of the support frame is connected to the stripping plate through a mounting rod, and a third scroll spring is nested on the outer side of the mounting rod.

[0022] A lower stamping module is correspondingly arranged above the stripping plate, and there is a spacing between the upper surface of the stripping plate and the lower surface of the lower stamping module.

[0023] Preferably, the lower part inside the second air storage pipe is connected to the lower part inside the first air storage pipe through an air delivery pipe.

[0024] An adjustable rod is installed in the slot inside the outer frame body below the lower stamping module. The adjustable rod is arranged above the stripping plate, and the stripping plate forms a rotating structure through the adjustable rod.

[0025] Preferably, a vertical rod is installed in a groove on the front side of the outer frame body on the left side of the upper stamping module. A straightening plate is slidably connected through the outside of the vertical rod. A connecting spring is nested and connected to the outside below the vertical rod. A follow-up control component is arranged above the straightening plate. The straightening plate and the outer frame body form a reciprocating lifting structure through the follow-up control component.

[0026] Preferably, the follow-up control component includes a cross rod installed on the front side of the outer frame body. The cross rod is arranged above the straightening plate. A first scroll spring is nested and connected to the rear end of the cross rod. Three groups of push plates are equidistantly installed on the outside of the cross rod. Each group has two push plates. The length of the push plate is greater than the shortest distance between the straightening plate and the cross rod.

[0027] A connecting rope is wound and connected to the outside of the middle part of the cross rod. The upper part of the connecting rope is connected to the cross plate through a guide wheel.

[0028] Preferably, rotating rods are installed in grooves on the left and right side surfaces of the straightening plate. Mounting frames are installed on the outside of the rotating rods. Smoothing rollers are installed below the mounting frames. A second scroll spring is nested and connected to the outside of the front end of the rotating rod.

[0029] Preferably, a second adsorption block is installed on the outside of the mounting frame. First adsorption blocks are installed in the grooves on the left and right sides of the straightening plate. The second adsorption block and the first adsorption block are made of magnet blocks with opposite magnetic poles.

[0030] Two fixing plates are symmetrically installed on the front side of the outer frame body. A mounting frame is arranged below the fixing plate.

[0031] Compared with the prior art, the beneficial effects of the present invention are as follows: The stamping machine for alloy materials with a self-feeding follow-up demolding mode. The feeding plates cooperate with each other not only to pull the alloy materials for intermittent feeding, but also to squeeze and clamp the alloy materials through the cooperation of the two feeding plates with a rectangular shape structure, so as to facilitate straightening the bending area of the alloy materials and enabling the alloy materials to enter the stamping area smoothly. Therefore, the later stamping effect and quality can be improved. Through the setting of the follow-up demolding mechanism, the upper stamping module rises to automatically demold. The structure is simple and no additional power source is required, saving production and manufacturing costs as well as later use costs. The specific content is as follows:

[0032] The rotation directions of the upper and lower control rods are opposite, which in turn makes the rotation directions of the two sprocket assemblies opposite. As a result, 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. At this time, the upper stamping module and the lower stamping module cooperate to perform stamping operations. By repeating such operations, not only can the feeding plates cooperate with each other to intermittently pull and feed the alloy material, but also the alloy material can be extruded and clamped through the cooperation of the two feeding plates with a rectangular shape structure, so as to facilitate straightening the bending area of the alloy material and making the alloy material enter the stamping area smoothly. Therefore, the later stamping effect and quality can be improved.

[0033] Through the setting of the follow-up demoulding mechanism, when the electric push rod drives the upper stamping module to move upward and reset, at this time the cross plate drives the second piston rod to move upward, and the gas inside then enters the second gas storage pipe. As a result, the first piston rod automatically drives the demoulding plate to move downward, so that the demoulding plate drives the stamped workpiece to move downward together, thus facilitating automatic demoulding as the upper stamping module rises. The structure is simple, without the need to use an additional power source, saving production and manufacturing costs as well as later use costs.

[0034] Furthermore, through the setting of the self-adjusting rod, the self-adjusting rod pushes one end of the demoulding plate that continues to descend, so that the demoulding plate that continues to descend is inclined, facilitating the automatic leftward sliding and collection of the stamped workpiece above the demoulding plate without the need for manual taking by the staff.

[0035] During the lifting and lowering process of the upper stamping module, the straightening plate can be driven to reciprocally lift and lower through the follow-up control component, thus facilitating the straightening plate to reciprocally press the alloy material below, 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 later stamping effect and quality.

[0036] At the same time, through the setting of the smoothing rollers, when the straightening plate descends to straighten the bending area of the alloy material, the smoothing rollers on the left and right sides of the straightening plate rotate outward at this time, so that the two groups of smoothing rollers cooperate to apply a pushing force to the bending area of the alloy material to push and smooth it to both sides, thus assisting the straightening plate to perform the straightening operation well.

[0037] Through the adsorption of the first adsorption block and the second adsorption block set with opposite magnetic poles, when the straightening plate rises, the two groups of smoothing rollers will not rotate in the reverse direction to apply an inward pushing force to the bending area of the alloy material. When the straightening plate rises to a certain level, the fixed fixing plate will apply a pushing force to the mounting frame, causing the mounting frame to drive the smoothing rollers to reset for the next use.

[0050] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0051] Please refer to Figures 1 - 11 , the present invention provides the following technical solutions:

[0052] Embodiment 1: The stamping machine for alloy materials with self-feeding and follow-up demolding mode in this embodiment, when in use, can not only perform self-feeding on alloy materials, but also enable the alloy materials to enter the stamping area smoothly, thereby improving the stamping effect and quality of the alloy materials in the later stage. The specific structure is referred to in the attached Figures 1 - 5 As shown in the figure, it includes an outer frame 1 and a feeding frame 2 installed on the left side of the outer frame 1; two groups of limiting rollers 3 are symmetrically installed on the left and right sides of the feeding frame 2, with two in each group; the inside of the feeding frame 2 is connected with a feeding plate 10 for intermittently pulling and self-feeding 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 with an upper stamping module 6 through a cross plate 5; a lower stamping module 7 is installed on the outer frame 1 below the upper stamping module 6, and a demolding plate 9 is connected to the inside of the outer frame 1 below the lower stamping module 7 through a follow-up demolding mechanism. The displacement control mechanism includes two groups of upper and lower control rods 13 installed through slots on the inner wall of the rear side of the feeding frame 2, and the outer sides of the two control rods 13 in each 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 the front end of the extension rod 141 is rotatably installed with a feeding plate 10; transmission gears 131 are installed on the outer sides of the rear ends of the upper and lower control rods 13 on the rightmost side, and the two transmission gears 131 are meshed and connected. The rotation directions of the upper and lower control rods 13 on the rightmost side are opposite. Slide rods 11 are installed through slots on the upper and lower side inner walls of the feeding frame 2, and a manual telescopic rod 12 is slidably connected to the outer side of the slide rod 11. One end of the manual telescopic rod 12 is connected to the outer side of the feeding plate 10; the shortest distance between the two feeding plates 10 is less than the shortest distance between the two limiting rollers 3.

[0053] First, place the coiled alloy material on an external loading rack. Then, insert one end of the coiled alloy material between two limiting rollers 3 for loading. Next, connect the rear end of the lower control rod 13 to an external motor. The motor drives the lower control rod 13 to rotate clockwise. When the lower control rod 13 rotates, it drives the sprocket assembly 14 to rotate clockwise. Then, the sprocket assembly 14 drives the lower loading plate 10 to first move upward and then move 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 sliding rod 11, so as to ensure that the lower loading plate 10 stably moves upward first and then to the right. At the same time, when the lower control rod 13 rotates clockwise, it drives the upper control rod 13 to rotate counterclockwise through two sets of meshing transmission gears 131 on the outside of the rear end. When the upper control rod 13 rotates counterclockwise, it drives the sprocket assembly 14 to rotate counterclockwise. Then, the sprocket assembly 14 drives the upper loading plate 10 to first move downward and then move to the right through the extension rod 141. At this time, the manual telescopic rod 12 on the upper surface of the upper loading plate 10 is stretched, and then the manual telescopic rod 12 slides on the outside of the upper sliding rod 11, so as to ensure that the upper loading plate 10 stably moves downward first and then to the right. Therefore, the upper and lower loading plates 10 clamp one end of the coiled alloy material and then pull it to the right for loading;

[0054] When the upper and lower loading plates 10 move to the rightmost side, similarly as described 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, so that the two loading plates 10 are separated from one end of the alloy material and no longer clamp one end of the alloy material. Then, when the upper and lower loading plates 10 move to the leftmost side, at this time, 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 again and pull it to the right for loading. By operating repeatedly in this way, the two loading plates 10 cooperate to intermittently pull one end of the alloy material for loading. This not only enables good self-loading, but also presses the alloy material in an extrusion manner through the cooperation of the two rectangular loading plates 10, so that the bent area of the alloy material can be straightened. Therefore, the alloy material enters the stamping area flatly. Then, when the loading plate 10 moves to the left, the alloy material stops being loaded at this time. Then, start the electric push rod 4. The output end of the electric push rod 4 drives the cross plate 5 and the upper stamping module 6 to move downward. Then, the upper stamping module 6 stamps the alloy material on the lower stamping module 7 into a workpiece of a certain shape. Then, the stamped workpiece falls onto the stripping plate 9.

[0055] Embodiment 2: The stamping machine for alloy materials with a self-feeding and follow-up demolding mode in this embodiment can automatically demold the formed workpiece through the follow-up demolding mechanism during use, without the need to additionally use a power source, saving energy and reducing the production and manufacturing costs. For the specific structure, refer to the appendix Figures 9 - 11 As shown, on the basis of Embodiment 1, the follow-up demolding mechanism includes a second piston column 25 installed at the rear side of the cross plate 5. The second piston column 25 is arranged in a "7" - shaped structure in the groove of the outer frame body 1; a second air storage pipe 26 is installed inside the outer frame body 1 at the rear side of the lower stamping module 7. The upper part inside the second air storage pipe 26 is in close connection with the second piston column 25. A first air storage pipe 22 is installed inside the outer frame body 1 below the lower stamping module 7. The upper part inside the first air storage pipe 22 is in close connection with a first piston column 23. The upper end of the first piston column 23 is installed with a support frame 20 in a "U" - shaped structure. The inner side of the support frame 20 is connected with a demolding plate 9 through a mounting rod 28. The outside of the mounting rod 28 is nested with a third scroll spring 27. A lower stamping module 7 is correspondingly arranged above the demolding plate 9. There is a spacing between the upper surface of the demolding plate 9 and the lower surface of the lower stamping module 7. The lower part inside the second air storage pipe 26 is connected with the lower part inside the first air storage pipe 22 through an air delivery pipe 24; an adjustable rod 21 is installed in the groove inside the outer frame body 1 below the lower stamping module 7. The adjustable rod 21 is arranged above the demolding plate 9. The demolding plate 9 forms a rotating structure through the adjustable rod 21.

[0056] When the output end of the electric push rod 4 drives the cross plate 5 and the upper stamping module 6 to move downward, at this time, the cross plate 5 drives the second piston column 25 installed at the rear side to move downward together. Then, the second piston column 25 pushes a part of the gas in the second air storage pipe 26 into the first air storage pipe 22 through the air delivery pipe 24. At this time, the gas in the first air storage pipe 22 automatically drives the first piston column 23 inside to move upward. At this time, the first piston column 23 drives the support frame 20 and the demolding plate 9 to move upward. When the demolding plate 9 moves to be separated from the upper end of the adjustable rod 21, at this time, the third scroll spring 27 automatically drives the mounting rod 28 to rotate in the reverse direction and reset through its stored energy. At this time, the mounting rod 28 drives the demolding plate 9 to rotate to a horizontal state. At this time, when the upper stamping module 6 and the lower stamping module 7 cooperate to perform a stamping operation, the stamped and formed workpiece will fall on the demolding plate 9. At this time, the stamped and formed workpiece is separated from the lower stamping module 7.

[0057] Then when the upper stamping module 6 moves upward, similarly as described above, the cross plate 5 drives the second piston rod 25 to move upward. At this time, the gas in the first air storage pipe 22 enters the second air storage pipe 26 through the air delivery pipe 24, and then the first piston rod 23 drives the support frame 20 and the stripping plate 9 to move downward. When the stripping plate 9 moves downward, the self-adjusting rod 21 that remains stationary applies a thrust to the right side of the stripping plate 9, causing the stripping plate 9 to rotate 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, facilitating the follow-up demolding and collection of the workpiece on the stripping plate 9.

[0058] Embodiment 3: The self-feeding follow-up demolding type stamping machine for alloy materials in this embodiment can further enable the alloy materials to enter the stamping area smoothly on the basis of Embodiment 1, thereby further improving the stamping effect and quality of the alloy materials in the later stage. The specific structure is as shown in the attached Figures 6 - 8 As shown, a vertical rod 101 is installed in a groove on the front side of the outer frame body 1 on the left side of the upper stamping module 6. A straightening plate 8 is slidably connected through the outside of the vertical rod 101. A connecting spring 102 is nested and connected to the outside of the lower part of the vertical rod 101. A follow-up control component is arranged above the straightening plate 8. The straightening plate 8 and the outer frame body 1 form a reciprocating lifting structure through the follow-up control component. The follow-up control component includes a cross bar 15 installed on the front side of the outer frame body 1. The cross bar 15 is arranged above the straightening plate 8. A first scroll spring 153 is nested and connected to the rear end of the cross bar 15. Three groups of push plates 152 are equidistantly installed on the outside of the cross bar 15, with two in each group. 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 and connected to the outside of the middle part of the cross bar 15. The upper part of the connecting rope 151 is connected to the cross plate 5 through a guide wheel. Rotating rods 19 are installed in grooves on the left and right sides of the straightening plate 8. Mounting frames 18 are installed on the outside of the rotating rods 19. Smoothing rollers 17 are installed below the mounting frames 18. A second scroll spring 191 is nested and connected to the outside of the front end of the rotating rod 19. Second adsorption blocks 181 are installed on the outside of the mounting frames 18. First adsorption blocks 81 are installed in the grooves on the left and right sides of the straightening plate 8. The second adsorption blocks 181 and the first adsorption blocks 81 are made of magnet blocks with opposite magnetic poles. Two fixing plates 16 are symmetrically installed on the front side of the outer frame body 1. The mounting frames 18 are arranged below the fixing plates 16.

[0059] When the horizontal plate 5 and the upper stamping module 6 move downward, the horizontal plate 5 will pull the connecting rope 151 on the left side at this time. Then, the left end of the connecting rope 151 drives the cross bar 15 to rotate. At this time, the first scroll spring 153 behind the cross bar 15 stores energy. When the cross bar 15 rotates, it will drive three groups of push plates 152 arranged at equal intervals to apply a downward thrust to the straightening plate 8 in turn. At this time, the rear side of the straightening plate 8 slides downward on the outside of the vertical rod 101, and at the same time, the connecting spring 102 is compressed to store energy. Then, the straightening plate 8 presses the alloy material on the lower stamping module 7 in an up-and-down reciprocating manner, thereby further straightening the alloy material.

[0060] 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 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 scroll spring 191 stores energy. During the process of the smoothing rollers 17 rotating outward, they will apply an outward smoothing thrust to the alloy material, which is convenient for further smoothing the alloy material, so that the straightening plate 8 can press the alloy material well in the later stage. When the smoothing rollers 17 rotate to a certain position, the second adsorption block 181 on the outside of the mounting bracket 18 adsorbs with the first adsorption block 81. After the straightening plate 8 rises, the smoothing rollers 17 do not rotate reversely to reset by the energy storage of the second scroll spring 191 first. Therefore, when the straightening plate 8 rises, the smoothing rollers 17 directly separate from the alloy material. Then, when the straightening plate 8 rises to a certain height position, the fixedly installed fixing plate 16 will apply a downward thrust to the mounting bracket 18, thereby separating the second adsorption block 181 from the first adsorption block 81. At this time, the smoothing rollers 17 can be rotated reversely to reset by the energy storage of the second scroll spring 191, which is convenient for the next use, thus completing a series of operations.

[0061] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
