Description

Technical Field

[0001] This invention belongs to the field of sheet metal stamping technology, and relates to a sheet metal stamping die, particularly a high-precision sheet metal stamping die that is easy to demold. Background Technology

[0002] Molds primarily achieve the shape of an object by changing the physical state of the material being molded. They are widely used in blanking, die forging, cold heading, extrusion, powder metallurgy pressing, pressure casting, and compression molding or injection molding of engineering plastics, rubber, ceramics, and other products. Stamping, on the other hand, is a forming process that uses a press and molds to apply external force to sheet metal, strip, tube, and profiles at room temperature, causing plastic deformation or separation to obtain workpieces of the desired shape and size. Stamping and forging both belong to plastic processing.

[0003] In the process of stamping sheet metal parts, in order to ensure product precision and consistency, special attention is generally paid to the following two aspects: Dies and Cutting Tools: Stamping dies require precise dimensions and excellent surface quality to reduce product deformation and die wear. Simultaneously, suitable cutting tools are needed to ensure the accuracy and surface quality of the cut edges.

[0004] Process control and inspection: During production, it is necessary to continuously monitor the accuracy and consistency of the products, and promptly identify and resolve problems. Methods such as statistical process control can be used to monitor the production process and ensure stable product quality.

[0005] In addition, continuous processing is required to improve the efficiency of stamping sheet metal parts, which necessitates easy demolding and high-precision molds to meet processing needs.

[0006] A search revealed a Chinese patent document disclosing a sheet metal stamping die [Application No.: 202223466584.0; Publication No.: CN219378592U]. This die includes a first die base and a second die base. The first die base has a first pressing block and a second pressing block adjacent to each other along a first direction. The second pressing block can move closer to or away from the first die base along a second direction. A second die assembly is movably connected to the first die base and can also move closer to or away from the first die base along the second direction. The second die base has a third pressing block. The side of the first pressing block facing the second pressing block has a first forming surface, and the side of the third pressing block facing the first forming surface has a second forming surface. The first forming surface is curved. The first forming surface and the second forming surface are arranged opposite to each other in the first direction and are used to press the sheet metal together. Although the shape of the first part of the sheet metal can be controlled by the shape of the first forming surface and the second forming surface, which is beneficial for processing sheet metal with curved surfaces, the forming method is singular, continuous processing is not possible, pressure detection function is lacking, stamping accuracy is low, and the efficiency of demolding and scrap removal is low.

[0007] Based on this, we propose a high-precision sheet metal stamping die that is easy to demold. It can be stably adjusted and fed, and can continuously perform punching, stamping and segmentation, stamping and forming, bending and forming, automatic demolding, scrap blanking and finished product demolding and discharge. It can also perform pressure detection to ensure processing accuracy. Summary of the Invention

[0008] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a high-precision sheet metal stamping die that is easy to demold. The technical problem to be solved by this invention is: how to achieve continuous punching, stamping segmentation, stamping forming, bending forming, automatic demolding, scrap blanking, and finished product demolding and discharge, and to enable pressure detection to ensure processing accuracy.

[0009] The objective of this invention can be achieved through the following technical solutions: A high-precision sheet metal stamping die with easy demolding includes a lower mounting base and an upper mounting base. A lower stamping mechanism is adjustablely provided above the lower mounting base. The lower stamping mechanism includes a material ejector and a stamping base plate arranged sequentially from bottom to top. A lower stamping assembly 1, a lower stamping assembly 2, and a lower stamping assembly 3 are arranged sequentially from front to back above the stamping base plate. An upper stamping mechanism is adjustablely provided below the upper mounting base. The upper stamping mechanism includes an assembly frame and a stamping top plate arranged sequentially from top to bottom. An upper stamping assembly 1 and an upper stamping assembly 2 are arranged sequentially from front to back below the stamping top plate. The stamping base plate and the stamping top plate are slidably connected. The lower stamping assembly 1 is drivenly connected to the front part of the upper stamping assembly 1 and the upper stamping assembly 2, respectively. The lower stamping assembly 2 and the lower stamping assembly 3 are drivenly connected to the upper stamping assembly 2, respectively. A material ejection conveyor chain is provided on the rear side of the material ejector.

[0010] The working principle of this invention is as follows: A processing plate is placed between upper stamping assembly one, upper stamping assembly two, lower stamping assembly one, lower stamping assembly two, and lower stamping assembly three. One end of the processing plate is inserted between upper stamping assembly one and lower stamping assembly one. The stamping top plate mates with upper stamping assembly one and upper stamping assembly two, respectively; the stamping bottom plate mates with lower stamping assembly one, lower stamping assembly two, and lower stamping assembly three, respectively; upper stamping assembly one mates with lower stamping assembly one; and the front portions of lower stamping assembly one and upper stamping assembly two are aligned. The upper and lower stamping components 2 and 3 work in conjunction with the upper stamping component 2 to sequentially and continuously punch, segment, form, bend, automatically demold, discharge scrap, and demold finished product onto the processing plate, forming two finished parts in one operation. During the punching, segmenting, and forming processes, pressure sensors provide high-precision detection. If the pressure exceeds the preset range, it indicates wear on the component, allowing for timely replacement to ensure the accuracy of the finished parts. The finished parts are then transferred from the discharge rack to the discharge conveyor chain for output.

[0011] The assembly frame has a symmetrical structure and is adjustablely positioned below the upper mounting base. The upper end of the assembly frame is provided with several hydraulic seats, which are symmetrically arranged on the left and right sides. The stamping top plate is fixed below the assembly frame. The lower four corners of the stamping top plate are fixed with lifting slide shafts and limit stops. The left and right sides of the stamping top plate are provided with baffles.

[0012] With the above structure, several hydraulic seats are connected to external hydraulic equipment to provide lifting power. The assembly frame is adjustablely set below the upper mounting seat to facilitate the adjustment of the assembly frame's position. Several hydraulic seats are used to adjust the height of the upper stamping component one and the upper stamping component two, facilitating functions such as punching, stamping segmentation, stamping forming, bending forming, and automatic demolding. The lifting slide shaft and limit stop are used to connect and limit the stamping top plate and stamping bottom plate to ensure stamping accuracy. The baffle is used to block dust and debris.

[0013] The upper stamping assembly includes a stamping plate. The upper end of the stamping plate is provided with a plurality of hydraulic push rods, a plurality of sliding connecting rods, and a plurality of limiting sleeve rods. The plurality of hydraulic push rods, sliding connecting rods, and limiting sleeve rods are symmetrically arranged. The plurality of sliding connecting rods and limiting sleeve rods are slidably sleeved on the stamping top plate. The upper ends of the plurality of hydraulic push rods are fixed to the lower ends of the hydraulic seats at corresponding positions. A plurality of stamping push rods are slidably arranged on the stamping plate. The upper ends of the plurality of stamping push rods are fixed to the lower ends of the stamping top plate. A stamping head is fixed to the lower ends of the stamping push rods.

[0014] Using the above structure, several hydraulic push rods drive the stamping plate to rise and fall, while several sliding connecting rods and several limiting sleeve rods slide on the stamping top plate to ensure the stability of the stamping plate's rise and fall and to ensure processing accuracy. When the stamping plate rises, the stamping push rods move relative to each other, which is equivalent to the stamping push rods being pushed out. The shape of the stamping head can be selected and installed as needed. Various shapes of stamping heads stamp the processing plate. After stamping is completed, several hydraulic push rods drive the stamping plate to fall, and the stamping push rods move relative to each other, which is equivalent to the stamping push rods being retracted for demolding. The punching and forming operation can be performed simultaneously.

[0015] The upper stamping assembly two includes a stamping plate two. The upper end of the stamping plate two is provided with several hydraulic push rods two, several sliding connecting rods two, and several limiting sleeve rods two. These hydraulic push rods two, sliding connecting rods two, and limiting sleeve rods two are symmetrically arranged. The sliding connecting rods two and limiting sleeve rods two are slidably sleeved on the stamping top plate. The upper ends of the hydraulic push rods two are fixed to the lower ends of the hydraulic seats one at corresponding positions. A first stamping part, a second stamping part, a third stamping part, and a fourth stamping part are sequentially slidably arranged on the stamping plate two. The components are a fifth stamped part, a sixth stamped part, a seventh stamped part, an eighth stamped part, and a ninth stamped part. The second stamped part is a punched part, the third and eighth stamped parts are punched and shaped parts, and the first, fourth, fifth, sixth, seventh, and ninth stamped parts are shaped parts. All the first, second, third, fourth, fifth, sixth, seventh, eighth, and ninth stamped parts have symmetrical structures.

[0016] Using the above structure, several hydraulic push rods 2 drive the stamping plate 2 to rise and fall, and several sliding connecting rods 2 and several limiting sleeve rods 2 all slide on the stamping top plate to ensure the stability of the stamping plate 2's rise and fall and to ensure processing accuracy. When the stamping plate 2 rises, the first stamping part, the second stamping part, the third stamping part, the fourth stamping part, the fifth stamping part, the sixth stamping part, the seventh stamping part, the eighth stamping part, and the ninth stamping part move relative to each other, which is equivalent to the first stamping part, the second stamping part, the third stamping part, the fourth stamping part, the fifth stamping part, the sixth stamping part, the seventh stamping part, the eighth stamping part, and the ninth stamping part being pushed out. The shapes of the first, second, third, fourth, fifth, sixth, seventh, eighth, and ninth stamped parts are selected and installed as needed. The installation process involves stamping the processing plate. After stamping, several hydraulic push rods drive the stamping plate to descend, causing the first, second, third, fourth, fifth, sixth, seventh, eighth, and ninth stamped parts to move relative to each other, which is equivalent to retraction and demolding. The process can simultaneously perform punching, stamping segmentation, stamping forming, and bending forming operations.

[0017] Both the first and second stamping plates are provided with a number of lifting pressure sensors and a number of positioning pins. The lifting pressure sensors and positioning pins are symmetrically arranged. One positioning pin and two lifting pressure sensors form a group. The two lifting pressure sensors are respectively located on both sides of the positioning pin. The punching heads of the stamping head, the second stamping part, the third stamping part, and the eighth stamping part are all provided with stamping pressure sensors.

[0018] With the above structure, the positioning pin is used to position the first and second stamping plates during stamping. Several lifting pressure sensors detect the pressure of the first and second stamping plates during stamping to ensure accurate pressure. If the pressure exceeds the preset range, it indicates that the component is worn, and the corresponding component should be replaced in time to ensure the processing accuracy of the finished part. The punching head, the second stamping part, the third stamping part, and the eighth stamping part are all equipped with stamping pressure sensors, which are also used to detect the pressure of the punching head, the second stamping part, the third stamping part, and the eighth stamping part through the stamping pressure sensors. If the pressure exceeds the preset range, it indicates that the component is worn, and the corresponding component should be replaced in time to ensure the processing accuracy of the finished part.

[0019] The discharge rack has a symmetrical structure and includes a base frame. Several inwardly inclined side seats are provided on several vertical walls of the base frame. Several sets of symmetrically arranged waste discharge hoppers are provided between the several vertical walls of the base frame. The waste discharge hoppers are located directly below the side inclined seats. A limit sensor is provided on the rear side of the base frame.

[0020] With the above structure, several equally spaced positioning through holes are opened on both sides of the processing plate. The waste discharge hopper is used to discharge the waste generated by stamping. The limit sensor cooperates with the positioning through holes to limit the movement of the processing plate, ensuring that the displacement of the feeding of the processing plate is the same each time it moves, so as to perform multiple continuous and stable operations and meet the processing accuracy requirements.

[0021] The stamping base plate includes a stamping base plate fixed above the vertical wall of the base frame. Several hydraulic seats and several side transfer buckets are fixed to the lower end of the stamping base plate. The side transfer buckets engage with the corresponding side inclined seats. Several punch discharge holes are provided on the stamping base plate. The position and shape of the punch discharge holes correspond to the punching heads of the stamping head, the second stamping part, the third stamping part, and the eighth stamping part. The punch discharge holes are located above the side transfer buckets and the waste discharge bucket. The stamping base plate has two symmetrical finished product inclined seats on the rear side. Finished product hoppers are fixed to the upper end of each finished product inclined seat. Several connecting and fixing plates are fixed to the left and right sides of the stamping base plate. The connecting and fixing plates are connected to the side of the stamping top plate. Linear bearing seats, connecting sleeves, and connecting sleeves are fixed to the four corners of the upper end of the stamping base plate. The lifting shaft is slidably set in the linear bearing seats at the corresponding positions. The connecting sleeve is connected to the lower end of the stamping top plate. The limit stop is slidably fitted into the connecting sleeve at the corresponding position.

[0022] Using the above structure, several hydraulic seats are connected to external hydraulic equipment. The position and shape of the discharge hole match the punching head of the stamping head, the second stamping part, the third stamping part, and the eighth stamping part. The punch discharge hole is located above the side transfer hopper and the waste discharge hopper, discharging waste material from the punch discharge hole. The waste material falls onto the side transfer hopper and the waste discharge hopper, and is discharged together through the side transfer hopper and the waste discharge hopper. After stamping, finished parts are formed. Finished parts slide out from the finished product chute. The connecting fixing plate is used to connect the stamping base plate and the stamping top plate. The lifting shaft is slidably set in the linear bearing seat at the corresponding position. The connecting sleeve is connected to the lower end of the stamping top plate. The limit stop is slidably sleeved in the connecting sleeve at the corresponding position to ensure the stable lifting of the stamping base plate and the stamping top plate, avoid displacement, and ensure the processing accuracy of the finished parts.

[0023] The lower stamping assembly includes a stamping plate three. Several punch limiting seats are detachably slidably provided on the stamping plate three. The punch limiting seats are fixed to the upper end of the stamping base plate. Punch limiting holes are opened inside the punch limiting seats. Stamping protrusions are provided at the upper ends of the punch limiting seats. Several hydraulic push rods three and several sliding sleeve rods one are fixed at the lower end of the stamping plate three. The hydraulic push rods three slide through the stamping base plate and the lower ends of the hydraulic push rods three are fixed on the hydraulic seats two at the corresponding positions. Several sliding sleeve rods one are slidably set on the stamping base plate. Several positioning holes are opened at the upper end of the stamping plate three. The positioning holes match the positioning pins at the corresponding positions.

[0024] With the above structure, the shape of the punch limiting hole is the same as that of the punch discharge hole below it. Several hydraulic push rods drive the stamping plate three to rise and fall, and several sliding sleeve rods slide on the stamping base plate to ensure the stability of the stamping plate three in rising and falling and to ensure processing accuracy. When the stamping plate three rises, several punch limiting seats move relative to each other, which is equivalent to several punch limiting seats retracting. The punch limiting seats stamp the processing plate. After stamping is completed, several hydraulic push rods drive the stamping plate three to fall, and several punch limiting seats move relative to each other, which is equivalent to the punch limiting seats being pushed out for demolding. The forming operation can be carried out simultaneously.

[0025] The lower stamping assembly 2 includes a stamping plate 4, on which a plurality of bending punches are slidably disposed. The plurality of bending punches are fixed to the upper end of the stamping base plate. A plurality of hydraulic push rods 4 and a plurality of sliding sleeve rods 2 are fixed to the lower end of the stamping plate 4. The hydraulic push rods 4 slide through the stamping base plate and the lower end of the hydraulic push rods 4 is fixed to the hydraulic seat 2 at the corresponding position. The plurality of sliding sleeve rods 2 are slidably disposed on the stamping base plate. A plurality of positioning holes are opened at the upper end of the stamping plate 4, and the positioning holes are matched with the positioning pins at the corresponding positions.

[0026] With the above structure, several hydraulic push rods drive the stamping plate four to rise and fall, and several sliding sleeve rods slide on the stamping base plate to ensure the stability of the stamping plate four during rise and fall and to ensure processing accuracy. When the stamping plate four rises, several bending punches move relative to each other, which is equivalent to several bending punches retracting. Several bending punches perform stamping processing on the processing plate. After stamping is completed, several hydraulic push rods drive the stamping plate four to fall, and several bending punches move relative to each other, which is equivalent to bending punches being pushed out for demolding. Forming operations can be performed simultaneously.

[0027] The lower stamping assembly three includes several synchronous sliding rods, several symmetrically arranged stamping die heads one, several symmetrically arranged stamping die heads two, and several symmetrically arranged stamping die heads three. Hydraulic push rods five are fixed to both sides of the lower end of each synchronous sliding rod. The hydraulic push rods five slide through the stamping base plate, and their lower ends are fixed to the corresponding hydraulic seats two. The several symmetrically arranged stamping die heads one, two, and three are located between two adjacent synchronous sliding rods, and are fixed to the upper end of the stamping base plate. Several positioning holes are provided at the upper end of each synchronous sliding rod, and these positioning holes match the corresponding positioning pins.

[0028] Using the above structure, several hydraulic push rods 5 drive the synchronous slide rod above them to rise and fall. When the synchronous slide rod rises, several stamping die heads 1, 2, and 3 move relative to each other, which is equivalent to the stamping die heads 1, 2, and 3 retracting. The stamping die heads 1, 2, and 3 stamp the processing plate. After stamping is completed, several hydraulic push rods 5 drive the synchronous slide rod above them to fall, and the stamping die heads 1, 2, and 3 move relative to each other, which is equivalent to the stamping die heads 1, 2, and 3 being pushed out for demolding. Synchronous forming operations can be performed.

[0029] Compared with existing technologies, this easy-to-release high-precision sheet metal stamping die has the following advantages: By cooperating with the lower mounting base and the discharge rack, and with the upper mounting base and the assembly rack, the positions of the discharge rack and the assembly rack can be stably adjusted and fixed. The stamping top plate is engaged with the upper stamping assembly one and the upper stamping assembly two respectively to stably perform stamping and demolding; The stamping base plate is engaged with the lower stamping assembly one, the lower stamping assembly two, and the lower stamping assembly three respectively to stably perform stamping and demolding. By cooperating with the front sections of the lower stamping assembly 1 and the upper stamping assembly 2, and by cooperating with the upper stamping assembly 2 respectively, the processing plate is continuously punched, stamped into blocks, stamped into shape, bent into shape, automatically demolded, scrapped, and finished product demolded and discharged. The pressure of the punch head, the second stamping part, the third stamping part, and the eighth stamping part is detected by the stamping pressure sensor. Several lifting pressure sensors detect the stamping pressure of the first stamping plate and the second stamping plate to ensure accurate pressure. If the pressure exceeds the preset range, it indicates that the part is worn and the corresponding part is replaced in time to ensure the processing accuracy of the finished part. The positioning holes match the positioning pins at the corresponding positions, and the limit stop slides into the connecting sleeve at the corresponding position to ensure the stable lifting and lowering of the stamping base plate and stamping top plate, avoid displacement, and ensure the processing accuracy of the finished parts.
