Description

Technical Field

[0001] The invention belongs to the technical field of stamping processing, and more specifically relates to a stamping process. Background Art

[0002] Stamping is a production technology that uses the power of conventional or special stamping equipment to directly subject sheet metal to deformation force in the die, thereby obtaining product parts with certain shapes, sizes and performances. Sheet metal, die and equipment are the three elements of stamping, which are divided into hot stamping and cold stamping according to the stamping temperature.

[0003] Patent document CN116604276A discloses a stamping process, including the following steps: first, the plate to be stamped is cleaned, and the cleaned plate is cut into stamping plates by a shearing machine. The stamping equipment performs a stretching forming operation on the plate to form a metal part of a desired shape by stretching the plate. At the same time, the metal parts produced by the stretching forming operation will improve the flexibility of the metal parts, thereby avoiding the process of forming the desired shape by striking the metal plate with a mold, which causes the surface of the metal part to become rough as the mold strikes the plate, and at the same time avoids the fact that the stamping forming operation does not have the function of stretching the metal.

[0004] The above-mentioned stamping process has certain shortcomings when used. The above-mentioned stamping process cannot be applied to continuous stamping operations. Continuous stamping operations are continuous stamping and shaping operations during the movement of materials. During the processing of metal tableware, the movement angle of the metal material will affect its punching effect. When the material is tilted, the material after stamping will appear defective. The above-mentioned process cannot correct the deviation of metal materials of any specifications. Secondly, during continuous stamping operations, the stamped metal material is easily stuck on the mold, making it impossible for the metal material to be quickly separated from the mold, interrupting its continuous stamping and reducing its stability. Secondly, the stamping process is a rough processing process, and there are metal burrs on the processed material. Therefore, the stamped metal material needs to be manually polished. The above-mentioned process cannot simultaneously perform grinding operations on materials of different thicknesses after stamping and shaping, which reduces its use effect. Summary of the invention

[0005] The purpose of the present invention is to provide a stamping process which can solve the existing problems.

[0006] The problem to be solved by the present invention is:

[0007] 1. The above stamping process is not suitable for continuous stamping operations. Continuous stamping operations are continuous stamping and shaping operations during the movement of materials. During the processing of metal tableware, the movement angle of the metal material will affect its punching effect. When the material is tilted, the material after stamping will be defective. The above process cannot correct the deviation of metal materials of any specifications;

[0008] 2. During the continuous stamping process, the stamped metal material is easily stuck on the die, making it impossible to quickly separate the metal material from the die, interrupting the continuous stamping and reducing its stability;

[0009] 3. The stamping process is a rough processing process, and the processed material has metal burrs. Therefore, the metal material after stamping needs to be manually polished. The above process cannot perform grinding operations on materials of different thicknesses simultaneously after stamping and finalization, which reduces its use effect.

[0010] The purpose of the present invention can be achieved through the following technical solutions:

[0011] A stamping process comprises the following steps:

[0012] Step 1: Place the metal material on the feeding base of the stamping equipment, clamp the two sides of the metal material with the limiting clamps, and drive the metal material to move through the feeding frame, so that the metal material is transported to the upper part of the stamping base;

[0013] Step 2: When the metal material passes through the space between the punching plate and the lower die body, the motor uses the driving plate to cooperate with the punching parts, and drives the punching plate to move up and down reciprocatingly through the ball head connecting rod. When the punching plate moves down, the punching plate cooperates with the upper die body to punch the surface of the metal material, so that the punch punches the metal material, and a part of the metal material passes through the lower die body and is discharged into the vibrating material plate;

[0014] Step 3: When the punching plate moves upward, the spring frame is driven downward by the spring, so that the spring frame separates the metal material from the punch at the lower part of the upper die body;

[0015] Step 4: Move the remaining metal material on the lower mold body to the inside of the grinding piece, and use the grinding wheel of the grinding piece to grind the burrs on the lower part of the metal material.

[0016] As a further technical solution of the present invention, when the limit clamp is in use, the first slide and the second slide are pulled at the same time, so that the telescopic rod is pulled out from between the first slide and the second slide. At the same time, the sliding clamp is used to make corresponding position adjustments at the lower parts of the first slide and the second slide to adjust the overall use length of the limit clamp.

[0017] As a further technical solution of the present invention, when the automatic rolling machine is in use, the adjusting bolts are rotated so that the two groups of adjusting bolts respectively drive the first clamping plate and the second clamping plate on the first slide and the second slide to move, so that the rollers of the first clamping plate and the second clamping plate are clamped on both sides of the metal material.

[0018] As a further technical solution of the present invention, when the vibrating material tray is in use, the eccentric wheel is driven to rotate by a motor, so that the eccentric wheel uses the lifting connecting rod to cooperate with the rotating clamp to drive the vibrating material tray, and the vibrating material tray cooperates with the rotating shaft at one end to perform reciprocating vibration, thereby discharging the metal material on the vibrating material tray from the receiving tray.

[0020] As a further technical solution of the present invention, the grinding wheel is driven to move by a motor. When the metal material passes through the grinding piece, the grinding wheel grinds the burrs on the bottom of the metal material. The grinding distance of the bottom of the metal material is adjusted by controlling the positions of the upper clamping wheel and the lower clamping wheel.

[0022] As a further technical solution of the present invention, when the stamping disk is in use, the upper mold body is spliced ​​and fixed to the lower part of the stamping disk by using a card slot. When the ball head connecting rod drives the upper mold body to move downward, the spring frame contacts the surface of the metal material, and the stamping disk continues to move downward, so that the punch passes through the spring frame and contacts the surface of the metal material.

[0023] As a further technical solution of the present invention, the stamping equipment includes a feeding base and a stamping base, the stamping base is fixedly mounted on the outer surface of one end of the feeding base, the outer surface of the upper end of the feeding base is provided with two groups of feeding frames and a group of limit clamps, the limit clamps are arranged between the two groups of feeding frames, the limit clamps include a first slide and a second slide, the first slide is movably mounted on one side of the second slide, a telescopic rod is movably sleeved between the first slide and the second slide, a first clamping plate is movably mounted on the upper part of the first slide, a second clamping plate is movably mounted on the upper part of the second slide, and the first slide and the first clamping plate, as well as the second slide and the second clamping plate, are all movably connected through adjusting bolts;

[0026] Beneficial effects of the present invention:

[0027] 1. When the stamping process is used to stamp metal tableware, the limit clamp can be used to perform feeding and correction operations on metal materials of any width to avoid tilting of the metal material during the stamping process and improve the stamping accuracy of the metal material. During operation, the user places the metal material to be stamped on the upper part of the limit clamp, first adjusts the overall width of the limit clamp according to the width of the metal material, and simultaneously pulls the first slide and the second slide to pull the telescopic rod out from between the first slide and the second slide. At the same time, the sliding card seat is used to make corresponding position adjustments at the lower part of the first slide and the second slide to adjust the overall use length of the limit clamp. According to the width of the metal material, the user rotates the limit clamp to adjust the overall use length of the limit clamp. The adjusting bolt adjusts the positions of the first clamping plate and the second clamping plate on the first slide and the second slide, so that the first clamping plate and the second clamping plate are respectively clamped on both sides of the metal material. At the same time, the setting of the roller can reduce the friction of the metal material when it moves between the first clamping plate and the second clamping plate, so that the metal material can be accurately moved between the upper mold body and the lower mold body. After the stamping is completed, the punched material falls to the upper part of the vibrating material disk, and the eccentric wheel is driven by the motor to rotate, so that the eccentric wheel uses the lifting connecting rod to cooperate with the rotating clamping seat to drive the vibrating material disk, and the vibrating material disk cooperates with the rotating shaft at one end to perform reciprocating vibration, thereby discharging the metal material on the vibrating material disk from the receiving disk, avoiding material accumulation and facilitating its discharge.

[0028] 2. When the stamping process is used to perform stamping operations on metal materials, a spring frame is used in conjunction with the spring setting to form an elastic material dividing structure at the bottom of the stamping disk to prevent the metal material from getting stuck on the punch and improve its stability during continuous stamping operations. During operation, the spring setting is used to provide an elastic material dividing structure between the spring frame and the stamping disk. When performing stamping operations, the upper mold body is spliced ​​and fixed to the bottom of the stamping disk using the card slot. When the ball head connecting rod drives the upper mold body downward, the spring frame contacts the surface of the metal material, and the stamping disk continues to move downward, so that the punch passes through the spring frame and contacts the surface of the metal material. After completing the stamping operation, the ball head connecting rod is used to drive the stamping disk to move upward. At this time, the spring drives the spring frame to move downward, so that the spring frame separates the metal material and the punch at the bottom of the upper mold body, thereby preventing the metal material from getting stuck on the punch, allowing the metal material to maintain smooth transportation and preventing it from getting stuck during stamping.

[0029] 3. When the stamping process is used to stamp metal materials, the setting of the grinding piece can be used to simultaneously grind off burrs on the metal material after stamping, thereby improving the stamping processing effect. During operation, the user loosens the lifting frame and the grinding piece by turning the fastening bolt, pulls the two ends of the lifting frame up and down, adjusts the height of the lifting frame in the grinding piece, and drives the lower clamping wheel to move up and down through the lifting frame. The user drives the lifting base plate through the bolt body, so that the lifting base plate drives the two sets of upper clamping wheels to move up and down, and at the same time, the lifting frame is used to drive the lower clamping wheel to move up and down, and the distance between the upper clamping wheel and the lower clamping wheel is adjusted according to the thickness of the metal material and the grinding position, so that the upper clamping wheel and the lower clamping wheel are attached to the surface of the metal material. The position adjustment of the upper clamping wheel and the lower clamping wheel can be used for metal materials of different thicknesses, and the grinding depth can be controlled at the same time. When the metal material moves, the grinding wheel is driven by a motor to complete the burr grinding operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0051] The operation of the punching disk 7 drives the ball head connecting rod 24 to reciprocate and rise and fall through the eccentric wheel 28 in the punching part 5, so that the ball head connecting rod 24 drives the punching disk 7 to do reciprocating punching movement up and down, and the motor drives the eccentric wheel 28 in the punching part 5 to rotate through the driving disk 6.

[0053] When the stamping plate 7 is in use, the upper mold body 19 is spliced ​​and fixed to the lower part of the stamping plate 7 by using the card slot. When the ball head connecting rod 24 drives the upper mold body 19 to move downward, the spring frame 21 contacts the surface of the metal material, and the stamping plate 7 continues to move downward, so that the punch 20 passes through the spring frame 21, so that the punch 20 contacts the surface of the metal material.

[0054] The stamping equipment includes a feeding base 2 and a stamping base 10. The stamping base 10 is fixedly mounted on the outer surface of one end of the feeding base 2.

[0057] When the stamping process is used to stamp metal tableware, the limit clamp 4 can be used to perform material feeding and correction operations on metal materials of any width, so as to avoid the metal material from tilting during the stamping process and improve the stamping accuracy of the metal material.

When the stamping operation is performed, the upper mold body 19 is spliced ​​and fixed to the lower part of the stamping disk 7 using the card slot. When the ball head connecting rod 24 drives the upper mold body 19 to move downward, the upper mold body 19 is moved downward.
