Description

Technical Field

[0001] The invention relates to the technical field of die stamping, in particular to a cold stamping device for an automobile reinforcement plate. Background Art

[0002] A stamping die is a special process equipment used to process materials (metal or non-metal) into parts (or semi-finished products) during cold stamping. It is called a cold stamping die (commonly known as a cold stamping die). Stamping is a pressure processing method that uses a stamping mechanism to drive the die to apply pressure to the material at room temperature to cause separation or plastic deformation, thereby obtaining the required parts. Most of the automotive sheet metal parts are stamped by stamping dies.

[0003] The current stamping methods are generally divided into two categories, one is hot stamping and the other is cold stamping. The hot stamping method is to press the workpiece after calcining it to a certain degree, while the cold stamping method is to directly press the workpiece into shape. Different processes are selected according to different workpiece types.

[0004] However, in the stamping process of automobile reinforcement plates, the existing technology generally directly uses a mold to press the plate, which has the following problems:

[0005] First, during the pressing process, due to the rigidity of the material, the mold needs to be in direct hard contact with the steel blank, which can easily cause scratches or scratches on the surface of the mold or steel. This requires the operator to continuously or indirectly spray lubricating liquid onto the mold or steel, which is inconvenient to operate.

[0006] Second: In the process of cold stamping, because it is extrusion molding, the mold and the product will definitely generate a certain amount of heat. With long-term processing, the heat of the mold will be higher, the degree of fatigue damage will be greater, and the life of the mold will be reduced;

[0007] Thirdly, in the process of cold stamping, due to the material of the steel billet, its deformation difficulty is more difficult than hot pressing during the pressing process. At this time, when the mold contacts the steel billet for stamping, a lot of noise will be generated, which will cause great discomfort to the surrounding working environment. Therefore, a cold stamping device for automobile reinforcement plates is proposed to solve the above-mentioned problems. Summary of the invention

DETAILED DESCRIPTION

[0036] 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.

[0037] See also Figure 1-Figure 10A cold stamping device for an automobile reinforcement plate comprises a die base 1; a hydraulic cylinder 3; a die pressing component 4 for cold pressing the reinforcement plate; a lubricating and cooling component 5 for lubricating and cooling the die pressing component 4 and the reinforcement plate parts to be stamped; a wiping component 6 for wiping and absorbing oil stains and water stains on the surface of the reinforcement plate after stamping; the die pressing component 4 is arranged inside the die base 1, the wiping component 6 is arranged on the die base 1, the lubricating and cooling component 5 is arranged at the bottom of the die base 1, a fixing frame 2 is fixedly installed on the die base 1, the hydraulic cylinder 3 is installed on the fixing frame 2, and the lubricating and cooling component 5 provides a cooling and lubricating environment during the pressing operation of the die pressing component 4, and can lubricate the die pressing component 4 while cooling it.

[0038] In this embodiment, the die pressing assembly 4 includes an upper die seat 401, the top of which is connected to the output end of the hydraulic cylinder 3, and the top of the upper die seat 401 is connected to two guide rods 402, which are slidably connected to the fixed frame 2. During the extension of the hydraulic cylinder 3, the upper die seat 401 will be driven to move downward, and then come into contact with the steel billet by extrusion, and the steel billet is stamped by means of upper pressure forming.

[0039] Furthermore, two side pressure rods 403 are connected to the output shaft of the hydraulic cylinder 3, and the surfaces of the two side pressure rods 403 are slidably connected to the side mold base 404, and the left mold 407 and the right mold 406 are respectively installed on the two side mold bases 404. A guide groove 4041 is provided inside the side mold base 404, and the side pressure rods 403 slide inside the guide groove 4041. A pull rod 405 is connected to one side of the side mold base 404, and the pull rod 405 is slidably connected to the mold base 1. During the downward movement of the two side pressure rods 403, they will contact the two side mold bases 404 through the inclined surfaces set on the surface, and then enter the guide groove 4041, and the inclined surfaces will squeeze the two side mold bases 404 to slide relative to each other, thereby controlling the left mold 407 and the right mold 406 to close the mold to clamp and position the steel billet, ensuring that the steel billet will not shift during the cold pressing process, and further improving the stability of the cold pressing process and the dimensional accuracy during the cold pressing process.

[0040] Furthermore, the lubrication and cooling assembly 5 includes a box body 501, an extrusion plate 502 is slidably connected inside the box body 501, one side of the extrusion plate 502 is connected to a connecting plate 503 through an axis rod, one end of the connecting plate 503 is fixedly connected to the pull rod 405, a mixed solution of lubricating and cooling liquid is arranged in the box body 501, two through openings are opened on the box body 501, and filter screens 504 are installed at the two through openings, and the surfaces of the two side mold bases 404 are slidably connected to the inner wall of the mold base 1. During the relative extrusion of the two side die seats 404, the extrusion plate 502 on the connecting plate 503 will be driven to move through the pull rod 405, and the extrusion plate 502 is similar to a "piston", which will squeeze the solution inside the box 501 and squeeze the solution out from the position of the two filters 504. At this time, the cold pressing area will be gradually occupied by the solution, because at this time the two side die seats 404 and the inner wall of the die seat 1 will form a long strip of processing cavity, and the stamping process is carried out in the processing cavity, so the technical solution is to squeeze the solution into the processing cavity to infiltrate the surface of the mold and the billet. After that, the stamping forming of the upper die seat 401 and the billet will be more lubricated and smooth, without the need for the operator to manually lubricate the mold or the billet, which is more convenient and stable, and solves the problem that the surface of the billet will be stamped and drawn due to the long-term action of the mold, thereby improving the quality of the cold pressed product.

[0041] In addition, a guide groove 4061 is provided on the right mold 406, the left mold 407 and the two side mold seats 404, and one end of the guide groove 4061 extends to the port position of the guide groove 4041. Through the set guide groove 4061, after the solution enters the interior of the processing chamber, a small stream of direct current will flow from the position of the guide groove 4061 and enter the interior of the guide groove 4041 to lubricate the surface of the side pressure rod 403. Because the side and inclined surface of the side pressure rod 403 always form a sliding contact with the side mold seat 404, the set guide groove 4061 can flow the lubricating liquid to the plane, ensuring the lubrication of the contact surface of the mold and improving the service life and stability of the equipment.

[0042] In addition, the wiping assembly 6 includes a cover plate 602, which is fixed above the mold base 1. One side of the cover plate 602 is rotatably connected to a connecting rod 1 604 and a connecting rod 2 605. One end of the connecting rod 1 604 and the connecting rod 2 605 are rotatably connected to a sponge frame, on which a sponge sheet 603 is installed. The connecting rod 1 604 is fixedly connected to a push rod 607. Round rods 606 are arranged on both sides of the push rod 607, and one end of the round rod 606 is fixed to the side mold base 404. When the side die seat 404 moves to the left, the round rod 606 on the right will contact the push rod 607 to drive the connecting rod 1 604 to rotate, and then the connecting rod 1 604 and the connecting rod 2 605 will drive the sponge sheet 603 on the sponge rack to rotate to the surface of the workpiece. Through the two groups of settings, the workpieces on both sides can be wiped and the water and oil stains on the surface of the forging can be absorbed to ensure the cleanliness of the reinforcement plate after forming, which is convenient for operators to take. The double-axis connecting rod setting of the connecting rod 1 604 and the connecting rod 2 605 is to ensure the parallel movement of the sponge sheet 603 according to the principle of parallelogram, and always keep its plane on the side plane of the workpiece to facilitate the subsequent comprehensive wiping.

[0043] It is worth noting that there are two wiping assemblies 6, and the two wiping assemblies 6 are symmetrically distributed with the center line of the mold base 1 as the symmetry axis. A fixing plate 601 is fixedly installed on the cover plate 602, and a groove is opened on the right side of the cover plate 602. Through the settings on both sides, it is possible to wipe the surfaces on both sides of the reinforcing plate, and it is an extrusion-type sponge wiping and absorption, and the purpose of setting the groove is to allow the sponge sheet 603 to follow the groove and flow to the inside of the processing chamber during extrusion, thereby realizing the reflux process. When the side mold base 404 moves to the right, the round rod 606 on the left will be used to drive the entire connecting rod 1 604 and the connecting rod 2 605 to rotate in the opposite direction, thereby driving the sponge sheet 603 to rotate out of the processing chamber and abut against the fixing plate 601, and finally squeezing the sponge sheet 603 to squeeze out the water stains absorbed by itself.

[0044] It is worth noting that the solution can also soak the surface of the workpiece in the processing chamber, and the dust and impurities on the surface will be removed, thereby reducing the error caused by the impurities and dust on the surface during cold pressing. Cleaning component 7, cleaning component 7 includes a support rod 701, one end of the support rod 701 is rotatably connected to the bottom of the left mold 407, the other end of the support rod 701 is rotatably connected to a mud pusher 702, one side of the mud pusher 702 is connected to a sliding rod 703, the sliding rod 703 is slidably connected to the mold base 1, and a contraction spring 704 is sleeved on the sliding rod 703, one end of the contraction spring 704 is connected to the mold base 1, and the other end of the contraction spring 704 is connected to the end of the sliding rod 703. The bottom of the mold base 1 is threadedly connected with three collecting sleeves 705, and the three collecting sleeves 705 are distributed on both sides of the filter screen 504 in pairs. When the left die 407 is reset, the sliding rod 703 is pulled by the contraction spring 704 to slide on the die base 1, and then the mud pusher 702 is moved, so that the mud pusher 702 slides to push the impurities deposited at the bottom, pushes the impurities into the middle hole, and finally deposits them in the collection sleeve 705 in the middle. During the extrusion process of the left die 407, the mud pusher 702 is opened through the connection of the support rod 701, and then the dirt on the other side is pushed to the circular hole position on both sides, and finally deposited in the collection sleeves 705 on both sides. The operator can remove the collection sleeve 705 from time to time through the threaded connection, pour out the dirt inside, and then reinstall it to achieve cleaning.

[0045] Working principle: first, the steel billet needs to be placed between the right die 406 and the left die 407. A step is set on the right die 406 to provide a position for placing the steel billet. Then, during the extension of the hydraulic cylinder 3, the upper die seat 401 will be driven to move downward, and the two side pressure rods 403 will be driven to move downward synchronously. During the downward movement of the two side pressure rods 403, they will contact the two side die seats 404 through the inclined surfaces set on the surface, and then enter the guide groove 4041. The inclined surfaces will squeeze the two side die seats 404 to slide relative to each other, thereby controlling the left die 407 and the right die 406 to close the mold to clamp and position the steel billet. After that, the inclined surfaces of the side pressure rods 403 will separate from the side die seats 404 and face each other. They will no longer control the movement of the two side die seats 404, but will only drive the upper die seat 401 to stamp and shape the steel billet through the direct connection of the hydraulic rod. During the relative extrusion of the two side mold seats 404, the extrusion plate 502 on the connecting plate 503 will be driven to move by the pull rod 405, and the extrusion plate 502 is similar to a "piston", which will squeeze the solution inside the box 501 and squeeze the solution out from the position of the two filter screens 504. At this time, the cold pressing area will be gradually occupied by the solution, because at this time, the inner wall of the two side mold seats 404 and the mold seat 1 will form a long strip processing cavity, and the stamping process is carried out in the processing cavity, so the technical solution is to squeeze the solution into the processing cavity to infiltrate the surface of the mold and the billet. After that, the stamping of the upper mold seat 401 and the billet will be more lubricated and smooth, and the operator does not need to manually lubricate the mold or the billet. At the same time, because the billet is in a natural room temperature state during the cold pressing process, the bending is low, and the extrusion noise generated by the cold pressing will also be reduced because the entire mold is in the solution. During the sliding of the side die seat 404 left and right, the two round rods 606 will also be driven to move. After the side die seat 404 moves to the left, the round rod 606 on the right will contact the push rod 607 to drive the connecting rod 1 604 to rotate. Then the connecting rod 1 604 and the connecting rod 2 605 will drive the sponge sheet 603 on the sponge rack to rotate to the surface of the workpiece. By setting up two groups, the workpieces on both sides can be wiped to absorb water and oil stains on the surface of the forgings, ensuring that the reinforcement plate is clean after forming, which is convenient for operators to take. When the side mold base 404 moves to the right, the round rod 606 on the left will drive the entire connecting rod 1 604 and the connecting rod 2 605 to rotate in the opposite direction, thereby driving the sponge sheet 603 to rotate out of the processing chamber and abut against the fixed plate 601, and finally squeezing the sponge sheet 603 to squeeze out the water stains absorbed by itself and return them to the processing chamber. This solution arranges a square sponge sheet 603, but it can actually be arranged into a cylindrical shape and the workpiece can be wiped by rolling, depending on the shape and requirements of the product.During the process of the overall hydraulic cylinder 3 shrinking and resetting, it means that the cold pressing is completed. After that, the two side mold seats 404 are reset, which will drive the lubrication and cooling assembly 5 to reset. At this time, the solution inside the processing chamber will flow back to the inside of the box 501 along the filter 504. The dry environment in the processing chamber when there is no operation is guaranteed, which is convenient for operators to place the steel billet. The solution can also soak the surface of the workpiece in the processing chamber, and the dust and impurities on the surface will be removed, thereby reducing the error caused by the impurities and dust on the surface during cold pressing. After the impurities are refluxed with the solution, they will be at the bottom of the processing chamber, that is, the bottom of the mold seat 1. When the left mold 407 is reset, the sliding rod 703 will be pulled by the contraction spring 704 to slide on the mold seat 1, and then the mud pusher 702 will be moved, so that the mud pusher 702 slides to push the impurities deposited at the bottom, push the impurities into the middle hole, and finally deposit them in the collection sleeve 705 in the middle position, ensuring the cleanliness of the bottom of the processing chamber. During the extrusion process of the left die 407, the mud pusher 702 will be opened through the connection of the support rod 701, and then the dirt on the other side will be pushed to the circular holes on both sides, and finally deposited in the collection sleeves 705 on both sides, realizing multi-directional cleaning.
