Description

Technical Field

[0001] This invention belongs to the field of metal hoop processing technology, and in particular relates to a metal hoop stamping and forming equipment. Background Technology

[0002] Metal clamps are commonly used for connecting, supporting, or fixing pipes, and are generally made of stamped metal. A metal clamp typically consists of two semi-circular rings, which are fixed to the outer wall of the pipe using bolts, nuts, or other fasteners, thus achieving pipe connection and fixation.

[0003] Metal clamps are mostly formed by stamping sheet metal or strip metal. The stamping process generally includes blanking of metal sheet metal (i.e., cutting the material to the required size), stamping and forming, and punching (i.e. forming the mounting holes of the metal clamp). The production process of metal clamps is complicated, requiring multiple turnovers and feeding of materials, and cannot be formed by stamping in one go.

[0004] A Chinese utility model patent (CN216757937U) discloses a batch integrated stamping forming equipment for metal clamps. A hydraulic cylinder drives an upper die plate to move vertically downwards along guide pillars, while a punch and upper die core move downwards to punch and perforate the raw metal sheet, obtaining a bent base plate. After punching, the hydraulic cylinder resets, causing the upper die plate to move upwards and reset, completing the punching action. The raw metal sheet then continues to be transported forward, with a feeding distance equal to the width of one metal clamp along the feeding direction. The bent base plate from the previous punching operation has entered the bending area. The hydraulic cylinder starts again and moves downwards, causing the upper bending die pressure plate to press against the bent base plate. The upper bending die core moves downwards, allowing the bent base plate to complete the bending operation under the pressure of the upper and lower bending dies, obtaining a bent semi-finished product. Simultaneously, a cutting punch cuts the connecting strip between the finished product and the bent semi-finished product obtained from the previous bending process, completing demolding and obtaining the finished metal clamp.

[0005] In summary, the above-mentioned utility model simply integrates multiple processes into a stamping die. In reality, each opening and closing of the stamping die corresponds to one of the processes of blanking, punching, and forming, requiring multiple material feedings. It is impossible to complete the production of metal clamps through a single material feeding and a single opening and closing of the stamping die. Summary of the Invention

[0006] The purpose of this invention is to provide a metal clamp stamping and forming equipment, which aims to solve the problem that the metal clamp manufacturing process is complicated and that existing metal clamp stamping and forming equipment cannot complete the production of metal clamps through one feeding and one opening and closing of the stamping die.

[0007] This invention is implemented as follows: a metal clamp stamping forming device includes a base, and further includes a die and a punch. The die is vertically slidably connected to the base, and a lower limit block is fixedly connected to the side wall of the die, the lower limit block being located above the base. A tension spring is fixedly connected to the lower end of the die, the end of the tension spring being fixedly connected to the lower end of the base. The punch is positioned directly above the die via a lifting assembly, the lifting assembly being used to drive the punch to move up and down. Two pressing rods are vertically slidably connected to the punch. A tension spring is fixedly connected to the upper end, and the end of the tension spring is fixedly connected to the upper end of the punch; a cutter seat is fixedly connected to the base, and the cutter seat is located at one end of the die; a locking assembly is provided on the punch, and when the punch moves the pressing rod downward, the locking assembly fixes the pressing rod on the punch until the pressing rod, together with the cutter seat, cuts the metal strip, and then the locking assembly releases the fixing restriction on the pressing rod; a punching assembly is provided on the punch, and after the die and punch finish punching the metal clamp, the punching assembly punches holes in the metal clamp.

[0008] In a further technical solution, a stop block is provided at the end of the die away from the cutter seat, and guide ribs protrude upward from the front and rear sidewalls of the upper end of the die, with a metal clamp placement groove formed between the two guide ribs.

[0009] In a further technical solution, the lifting assembly includes a top plate and a mounting plate. The punch is fixedly connected to the lower end of the mounting plate, and two guide columns are fixedly connected to the upper end of the base. The mounting plate is slidably connected to the two guide columns, and the top plate is fixedly connected to the upper end of the two guide columns. A telescopic cylinder is fixedly connected to the upper end of the mounting plate, and the telescopic end of the telescopic cylinder penetrates downward through the top plate and is fixedly connected to the mounting plate.

[0010] A further technical solution includes a sliding groove on the punch, in which a sliding block is slidably connected; a spring and a limiting block are fixedly connected to one end of the sliding block near the pressing rod, and a pushing wedge is fixedly connected to the other end of the sliding block; a limiting hole that mates with the limiting block is provided on the pressing rod; a movable wedge is vertically slidably connected to the top plate; a tension spring is fixedly connected to the upper end of the movable wedge, and the end of the tension spring is fixedly connected to the upper end of the top plate.

[0011] In a further technical solution, the punching assembly includes a punching hole provided on the die, the punching hole having a convex cross-sectional shape; a punching shaft is provided on the punch, and a telescopic cylinder II is fixedly connected to the punch, the telescopic end of the telescopic cylinder II being fixedly connected to the upper end of the punching shaft.

[0012] A further technical solution includes a demolding assembly on the die cavity, comprising a connecting plate. A first demolding shaft and a second demolding shaft are slidably connected to the die cavity. The lower ends of the first and second demolding shafts are fixed to the connecting plate. A fourth tension spring is fixedly connected to the upper end of the connecting plate, and the upper end of the fourth tension spring is fixed to the lower end of the die cavity. An installation groove is provided on one side wall of the demolding shaft. A rope groove is provided on the die cavity, and a rope is placed in the rope groove. One end of the rope is fixed to the upper end of the installation groove, and the other end of the rope is fixed to the lower end of the base.

[0013] A further technical solution includes a feeding assembly on the base, comprising a fixed seat fixedly connected to the upper end of the base, a movable feeding block horizontally slidably connected to the fixed seat, a tension spring five fixedly connected to the end of the movable feeding block away from the die, and the end of the tension spring five fixed to the fixed seat; a through clearance groove is vertically provided on the movable feeding block, a push surface is provided on the clearance groove, and a fixed wedge is fixedly connected to the side wall of the punch, the punch cooperating with the push surface.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] 1. When the punch moves the two pressing rods downward, the locking assembly fixes the pressing rods on the punch. The pressing rods press the metal strip and overcome the elastic force of the tension spring and drive the die downward. The pressing rods work with the cutter seat to cut the metal strip, thereby completing the feeding of the metal strip.

[0016] 2. When the die can no longer move downwards and the punch continues to move downwards, the tension spring two is gradually stretched. At this time, the pressing rod plays a pre-compression role on the metal strip.

[0017] 3. This invention can complete the feeding, stamping and punching of metal strips by opening and closing the die in sequence, simplifying the production process of metal clamps and improving the production efficiency of metal clamps. Attached Figure Description

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0029] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0030] like Figures 1-5As shown, a metal clamp stamping forming device according to an embodiment of the present invention includes a base 101, and further includes a die 102 and a punch 103. The die 102 is vertically slidably connected to the base 101. A lower limit block 105 is fixedly connected to the side wall of the die 102, and the lower limit block 105 is located above the base 101. A tension spring 106 is fixedly connected to the lower end of the die 102, and the end of the tension spring 106 is fixedly connected to the lower end of the base 101. The punch 103 is positioned directly above the die 102 via a lifting assembly 2, which is used to drive the punch 103 to move up and down. Two pressing rods 107 are vertically slidably connected to the punch 103. A tension spring 108 is fixedly connected to the upper end of the die 107, and the end of the tension spring 108 is fixedly connected to the upper end of the punch 103; a cutter seat 104 is fixedly connected to the base 101, and the cutter seat 104 is located at one end of the die 102; a locking assembly 3 is provided on the punch 103, and when the punch 103 drives the pressing rod 107 to move downward, the locking assembly 3 fixes the pressing rod 107 on the punch 103 until the pressing rod 107 and the cutter seat 104 cut the metal strip, and then the locking assembly 3 releases the fixing restriction on the pressing rod 107; a punching assembly 4 is provided on the punch 103, and after the die 102 and the punch 103 finish punching the metal clamp, the punching assembly 4 punches holes in the metal clamp.

[0031] In this embodiment of the invention, in the initial state, the tension spring 106 pulls the die 102 upward, and the upper end of the die 102 is at the same horizontal plane as the upper end of the cutter seat 104. In use, one end of the metal strip is placed on the die 102 and the cutter seat 104. The lifting assembly 2 drives the punch 103 downward, and the punch 103 drives the two pressing rods 107 downward. At this time, the locking assembly 3 fixes the pressing rods 107 on the punch 103. The pressing rods 107 press the metal strip, and overcome the elastic force of the tension spring 106, driving the die 102 downward. The pressing rods 107, in conjunction with the cutter seat 104, cut the metal strip, thus completing the feeding of the metal strip. After the pressing rods 107 and the cutter seat 104 cut the metal strip, the locking assembly 3 releases the pressing rods. With the fixed restriction of 107, after the lower limit block 105 contacts the upper end of the base 101, the die 102 cannot continue to move downward. When the punch 103 continues to move downward, the tension spring 108 is gradually stretched. At this time, the pressing rod 107 plays a pre-pressing role on the metal strip until the punch 103 and the die 102 complete the mold closing. When the punch 103 and the die 102 are in the pressure holding state, the punching assembly 4 punches the metal clamp, thereby cutting out the mounting hole of the metal clamp, thus completing the stamping of the metal clamp. The lifting assembly 2 drives the punch 103 to move upward and reset. The present invention can complete the feeding, stamping and punching operation of the metal strip by opening and closing the die 102 and the punch 103 in sequence, simplifying the production process of the metal clamp and improving the production efficiency of the metal clamp.

[0032] like Figure 4 As shown, in a preferred embodiment of the present invention, a stop block 110 is provided at one end of the die 102 away from the cutter seat 104, and guide ribs 109 protrude upward from the front and rear sidewalls of the upper end of the die 102, and a metal clamp placement groove is formed between the two guide ribs 109.

[0033] In this embodiment of the invention, the metal clamp placement groove formed between the two guide ribs 109 can guide the feeding of the metal strip, and the stop block 110 is used to control the feeding length of the metal strip.

[0034] like Figures 1-3 As shown, in a preferred embodiment of the present invention, the lifting assembly 2 includes a top plate 202 and a mounting plate 203. The punch 103 is fixedly connected to the lower end of the mounting plate 203, and two guide columns 201 are fixedly connected to the upper end of the base 101. The mounting plate 203 is slidably connected to the two guide columns 201, and the top plate 202 is fixedly connected to the upper end of the two guide columns 201. A telescopic cylinder 204 is fixedly connected to the upper end of the mounting plate 203, and the telescopic end of the telescopic cylinder 204 extends downward through the top plate 202 and is fixedly connected to the mounting plate 203.

[0035] In this embodiment of the invention, the telescopic cylinder 204 can be a hydraulic cylinder, a pneumatic cylinder, or an electric telescopic rod; when the telescopic cylinder 204 extends or retracts, under the guidance of the guide column 201, it can drive the mounting plate 203 to move up and down, and the mounting plate 203 drives the punch 103 to move up and down.

[0036] like Figures 1-6 As shown, in a preferred embodiment of the present invention, the locking assembly 3 includes a sliding groove 301 provided on the punch 103, and a sliding block 302 slidably connected in the sliding groove 301; a spring 303 and a limiting block 304 are fixedly connected to one end of the sliding block 302 near the pressing rod 107, and a pushing wedge 306 is fixedly connected to the other end of the sliding block 302; a limiting hole 305 that cooperates with the limiting block 304 is provided on the pressing rod 107; a movable wedge 307 is vertically slidably connected to the top plate 202; a tension spring 308 is fixedly connected to the upper end of the movable wedge 307; and the end of the tension spring 308 is fixedly connected to the upper end of the top plate 202.

[0037] In this embodiment of the invention, in the initial state, the limiting block 304 is inserted into the limiting hole 305, and the movable wedge 307 blocks the pushing wedge 306, thus preventing the pushing wedge 306 from extending out of the sliding groove 301. The limiting block 304 cannot disengage from the limiting hole 305. At this time, the punch 103 is fixedly connected to the pressing rod 107, and the elastic coefficient of the tension spring 308 is much greater than that of the spring 303. The punch 103 drives the pressing rod 107 to move downwards, and the downward-moving pressing rod 107, in conjunction with the cutter seat 104, cuts the metal strip. Subsequently, the pushing wedge 306 moves below the movable wedge 307, the movement restriction of the pushing wedge 306 disappears, the spring 303 pushes the sliding block 302 to move, and the sliding block 302 drives the limiting block 304 to disengage from the limiting hole 305. The die 102 can no longer move downwards. After the movement, the punch 103 continues to move downwards. At this time, the second tension spring 108 begins to stretch, and the pressing rod 107 pre-presses the metal strip. When the punch 103 drives the pressing rod 107 to move upwards, the second tension spring 108 pulls the pressing rod 107 downwards relative to the punch 103. When the pushing wedge 306 contacts the movable wedge 307, since the limiting block 304 has not yet coincided with the limiting hole 305, the pushing wedge 306 first overcomes the elastic force of the third tension spring 308 and pushes the movable wedge 307 upwards until the pressing rod 107 is reset. The limiting block 304 coincides with the limiting hole 305, and the movable wedge 307 overcomes the elastic force of the first spring 303 and pushes the pushing wedge 306, the sliding block 302, and the limiting block 304 to move, so that the limiting block 304 is inserted into the limiting hole 305. At this time, the punch 103 is reset.

[0038] like Figures 1-5As shown, in a preferred embodiment of the present invention, the punching assembly 4 includes a punching hole 401 provided on the die 102, the punching hole 401 having a convex cross-sectional shape; a punching shaft 402 is provided on the punch 103, and a telescopic cylinder 403 is fixedly connected to the punch 103, the telescopic end of the telescopic cylinder 403 being fixedly connected to the upper end of the punching shaft 402.

[0039] In this embodiment of the invention, the telescopic cylinder 403 can be a hydraulic cylinder, a pneumatic cylinder, or an electric telescopic rod; when the die 102 and the punch 103 are closed and in a pressure-holding state, the telescopic cylinder 403 extends, and the telescopic cylinder 403 drives the punch shaft 402 to move downward. The punch shaft 402 cooperates with the punching hole 401 to punch the metal clamp. The punching hole 401 is narrow at the top and wide at the bottom to facilitate the discharge of punching waste; after punching is completed, the telescopic cylinder 403 retracts, and the telescopic cylinder 403 drives the punch shaft 402 to move upward and reset.

[0040] like Figure 7 and Figure 8 As shown in a preferred embodiment of the present invention, a demolding assembly 5 is provided on the die 102. The demolding assembly 5 includes a connecting plate 503. A demolding shaft 1 501 and a demolding shaft 2 502 are slidably connected on the die 102. The lower ends of the demolding shaft 1 501 and the demolding shaft 2 502 are fixed on the connecting plate 503. A tension spring 4 504 is fixedly connected to the upper end of the connecting plate 503. The upper end of the tension spring 4 504 is fixed to the lower end of the die 102. An installation groove 505 is provided on the side wall of the demolding shaft 1 501. A rope groove 506 is provided on the die 102. A rope 507 is provided in the rope groove 506. One end of the rope 507 is fixed to the upper end of the installation groove 505, and the other end of the rope 507 is fixed to the lower end of the base 101.

[0041] In this embodiment of the invention, when the die 102 overcomes the elastic force of the tension spring 106 and moves downward, one end of the rope 507 is pulled by the base 101, thereby causing the rope 507 to overcome the elastic force of the tension spring 404 and drive the demolding shaft 101, the connecting plate 503, and the demolding shaft 202 to move downward, so that the demolding shaft 101 and the demolding shaft 202 are retracted inside the die 102, making the inner wall of the die 102 smooth and improving the stamping effect of the metal clamp; When mold 102 and punch 103 open, die 102 moves upward and resets, the tension on rope 507 disappears, tension spring 4 504 pulls connecting plate 503 upward, connecting plate 503 drives demolding shaft 1 501 and demolding shaft 2 502 to move upward, thereby causing demolding shaft 1 501 and demolding shaft 2 502 to push the metal clamp inside die 102 upward, thereby completing the demolding of the metal clamp and preventing the metal clamp from getting stuck in die 102.

[0042] like Figure 1 , Figure 2 and Figure 9 As shown in a preferred embodiment of the present invention, a feeding assembly 6 is provided on the base 101. The feeding assembly 6 includes a fixed seat 602 fixedly connected to the upper end of the base 101. A movable feeding block 601 is horizontally slidably connected to the fixed seat 602. A tension spring 603 is fixedly connected to one end of the movable feeding block 601 away from the die 102. The end of the tension spring 603 is fixed to the fixed seat 602. A through clearance groove 604 is vertically provided on the movable feeding block 601. A push surface 605 is provided on the clearance groove 604. A fixed wedge 606 is fixedly connected to the side wall of the punch 103. The punch 103 cooperates with the push surface 605.

[0043] In this embodiment of the invention, in the initial state, the fixed wedge 606 is not inserted into the clearance groove 604. The tension spring 603 pulls the movable blanking block 601, thereby placing the movable blanking block 601 inside the die cavity 102. At this time, with the cooperation of the movable blanking block 601, the arc-shaped cavity at the upper end of the die cavity 102 is filled, and the upper end of the die cavity 102 is smooth, which facilitates the feeding of metal strips at the upper end of the die cavity 102. When the punch 103 moves downward, the punch 103 drives the fixed wedge 606 to move downward. The fixed wedge 606 extends into the clearance groove 604, and the fixed wedge 606 pushes the push surface 605, thereby making the fixed wedge... Block 606 overcomes the elastic force of tension spring 603 and pushes the movable blanking block 601 to move, causing the movable blanking block 601 to disengage from the die 102. When the die 102 and the punch 103 open, the fixed wedge 606 moves upward. After the die 102 moves upward and resets, the fixed wedge 606 disengages from the clearance groove 604. Tension spring 603 pulls the movable blanking block 601 into the die 102, thereby pushing out the metal clamp formed in the die 102, completing the unloading of the die 102. This can prevent workers from putting their hands between the die 102 and the punch 103, improving safety in the production process.

[0044] The above embodiments of the present invention provide a metal clamp stamping forming device. In use, the movable blanking block 601 is located inside the die 102, and the arc-shaped cavity at the upper end of the die 102 is filled. One end of a metal strip is placed on the die 102 and the cutter seat 104. The telescopic cylinder 204 extends, and under the guidance of the guide column 201, the telescopic cylinder 204 drives the mounting plate 203 to move downwards. The mounting plate 203 drives the punch 103 to move downwards, and the punch 103 drives the fixed wedge 606 and two pressing rods 107 to move downwards. The fixed wedge 606 extends into the clearance groove 604 and pushes the push surface 605, thereby causing the fixed wedge 606 to overcome the elastic force of the tension spring 603 and push the movable blanking block 601 to move, thus causing the movable blanking block 601 to move. The material block 601 detaches from the die 102. At this time, the limiting block 304 is inserted into the limiting hole 305, and the pressing rod 107 is fixed on the punch 103. The pressing rod 107 presses the metal strip and overcomes the elastic force of the tension spring 106, causing the die 102 to move downward. One end of the rope 507 is pulled by the base 101, which in turn causes the rope 507 to overcome the elastic force of the tension spring 404 and drive the demolding shaft 1 501, the connecting plate 503, and the demolding shaft 2 502 to move downward, so that the demolding shaft 1 501 and the demolding shaft 2 502 retract into the die 102. The pressing rod 107, in conjunction with the cutter seat 104, cuts the metal strip, thus completing the feeding of the metal strip. After the pressing rod 107, in conjunction with the cutter seat 104, cuts the metal strip, the wedge 30 is pushed. 6. Move to below the movable wedge 307, pushing the wedge 306 to remove its movement restriction. Spring 1 303 pushes the sliding block 302 to move. The sliding block 302 causes the limiting block 304 to disengage from the limiting hole 305. After the lower limit block 105 contacts the upper end of the base 101, the die 102 can no longer move downward. At this time, the tension spring 2 108 begins to be stretched, and the pressing rod 107 pre-presses the metal strip until the punch 103 and die 102 complete the mold closing. When the punch 103 and die 102 are in the holding pressure state, the telescopic cylinder 2 403 extends. The telescopic cylinder 2 403 drives the punch shaft 402 to move downward. The punch shaft 402 cooperates with the punching hole 401 to punch the metal clamp, thereby cutting out the mounting hole of the metal clamp. After punching is completed, the telescopic cylinder 2 extends. When cylinder 2 (403) retracts, it drives the punch shaft 402 to move upward and reset, thus completing the stamping of the metal clamp. When cylinder 1 (204) retracts, under the guidance of the guide post 201, it drives the mounting plate 203 to move upward. The mounting plate 203 drives the punch 103 to move upward. The punch 103 drives the pressing rod 107 and the fixing wedge 606 to move upward and reset. The die 102 moves upward and resets. The tension on the rope 507 disappears, and the tension spring 4 (504) pulls the connecting plate 503 upward. The connecting plate 503 drives the demolding shaft 1 (501) and demolding shaft 2 (502) to move upward, which in turn pushes the metal clamp inside the die 102 upward, thus completing the demolding of the metal clamp.The fixed wedge 606 disengages from the clearance groove 604, and the tension spring 603 pulls the movable blanking block 601 into the die cavity 102, thereby pushing out the formed metal clamp from the die cavity 102, completing the unloading of the die cavity 102. This avoids workers from putting their hands between the die cavity 102 and the punch 103, improving safety during the production process. This invention, through the sequential opening and closing of the die cavity 102 and the punch 103, can complete the feeding, stamping, and punching operations of the metal strip, simplifying the production process of the metal clamp and improving its production efficiency.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
