Description

Technical Field

[0001] The utility model relates to the technical field of bottle cap production equipment, in particular to a continuous stamping and forming device for processing metal bottle caps. Background Art

[0002] The traditional processing method of metal bottle caps is carried out in two steps. First, a metal sheet is punched out on a metal strip by a punching device, and then the metal sheet is placed in a stamping device. The metal sheet is punched into shape by the stamping device to obtain a metal bottle cap. At the same time, during the punching and forming operations, the metal sheet is prone to move, resulting in stamping deviations and affecting product quality. In addition, traditional processing methods mostly rely on manual placement of metal sheets into stamping equipment, which reduces production efficiency to a certain extent.

[0003] Based on the above situation, in the prior art, the patent with publication number CN117259544B discloses a metal bottle cap stamping and forming device, which is mainly composed of a base, a conveying unit and a stamping unit. The conveying unit includes an intermittent motor located at the lower end of the base, and the motor drives the rotating shaft and the circular support plate to rotate. The circular through holes evenly distributed on the support plate are used to place the metal bottle caps to be stamped, and are equipped with a positioning assembly to ensure that the bottle caps are accurately positioned. The annular frame is connected to the circular support plate and realizes up and down movement through a lifting assembly. The lifting assembly is composed of a support block, a push block, a contact rod, a reset spring and a lifting member. Through the interaction between the support block and the contact rod, and the elastic force of the reset spring, the annular frame and the circular support plate are pushed up or down to cooperate with the stamping unit to stamp the metal bottle cap. The above-mentioned stamping and forming device can realize continuous stamping and forming of the metal bottle cap through the base, the conveying unit and the stamping unit. The positioning assembly in the stamping unit can fix the position of the bottle cap and the circular metal sheet to prevent the metal sheet from moving during the stamping process, thereby improving the stamping accuracy and the quality of the bottle cap molding.

[0004] However, the above-mentioned stamping and forming device still has room for improvement in light of actual conditions. The above-mentioned stamping and forming device is structurally equipped with a corresponding feeding component. When feeding, it may be necessary to manually place the metal sheet into the circular through hole of the stamping unit, which reduces the production efficiency to a certain extent. At the same time, the above-mentioned stamping and forming device can only process metal sheets that have been punched out, and cannot achieve one-time processing and forming of the metal strip to the bottle cap through one device, which reduces the practicability of the equipment to a certain extent.

DETAILED DESCRIPTION

[0023] like Figures 1 to 6 As shown, the utility model provides a technical solution: a continuous stamping and forming device for processing metal bottle caps, comprising a base 1, a movably connected turntable 11 is provided on the top of the base 1, a movably connected fixing column 13 is provided inside the turntable 11, a punching assembly 4, a punching assembly 5 and a discharging assembly 7 are arranged around the turntable 11 along the circumferential direction, the punching assembly 4, the punching assembly 5 and the discharging assembly 7 are arranged in sequence along the feeding direction and connected to the top of the base 1, the turntable 11 is provided with a rotationally symmetrically distributed forming assembly 2 near the edge position, the forming assembly 2 is provided with a rotationally symmetrically distributed positioning assembly 3 along the circumferential direction, the punching assembly 4 is symmetrically provided with a clamping assembly 6 connected to the top of the base 1 on the left and right sides, the forming assembly 2 is provided with a forming groove 21 and a first annular cut groove 22 on the surface of the turntable 11, a top material assembly 23 is provided inside the forming groove 21, the first annular cut groove 22 is rotationally symmetrically distributed on the periphery of the forming groove 21, a positioning groove 31 is provided between adjacent first annular cut grooves 22, and the positioning assembly 3 is arranged inside the positioning groove 31.

[0024] The utility model can realize one-time processing and forming of the metal strip to the bottle cap through the mutual cooperation among the forming component 2, the positioning component 3, the punching component 4, the stamping component 5 and the clamping component 6, which can effectively improve the processing efficiency of the bottle cap. The clamping components 6 arranged on the left and right sides of the punching component 4 can clamp the metal strip, so that the first annular groove 22 of the forming component 2 and the second annular groove 33 of the positioning component 3 cooperate with the punching component 4 to punch the metal strip into a metal disc that can be used for processing the bottle cap. After the punching is completed, the positioning component 3 The metal disc is moved closer to the molding groove 21 of the molding component 2 to position and fix the metal disc, thereby increasing the molding quality when the stamping component 5 stamps the metal disc into a bottle cap. The stamping component 5 stamps the metal disc into a bottle cap through the molding groove 21. After the stamping is completed, the ejecting component 23 ejects the bottle cap inside the molding groove 21. This process is then coordinated with the discharging component 7.

The entire structure is driven by the first drive motor 17 to realize the rotation function of the turntable 11. The first drive motor 17 is a stepping motor. The first drive motor 17 drives the turntable 11 to rotate 90° counterclockwise each time.

[0027] like Figure 1 As shown, as a preferred embodiment of the utility model, the clamping assembly 6 includes a mounting frame 61, an upper clamping roller 62, a lower clamping roller 63, a third gear 64, a chain 65, and a second drive motor 66. The upper clamping roller 62 and the lower clamping roller 63 are arranged in parallel up and down, and both ends of the upper clamping roller 62 and the lower clamping roller 63 are installed between the mounting frame 61. The ends of the roller shafts on the same side of the upper clamping roller 62 and the lower clamping roller 63 are respectively connected to the third gear 64, and the third gears 64 are connected to each other through a chain 65. The roller shaft of the lower clamping roller 63 passes through the third gear 64 and is fixedly connected to the power output shaft of the second drive motor 66.

[0028] The clamping assembly 6 is used to clamp and move the metal strip, so that the punching assembly 4 punches out metal discs from the metal strip through the forming assembly 2. The clamping assembly 6 includes a first clamping assembly 67 and a second clamping assembly 68. The components of the first clamping assembly 67 and the second clamping assembly 68 and the connection relationship between the internal components are the same. They are both composed of a mounting frame 61, an upper clamping roller 62, a lower clamping roller 63, a third gear 64, a chain 65, and a second drive motor 66. When punching, the metal strip can be pulled through the upper clamping roller 62 and the lower clamping roller 63 of the first clamping assembly 67. And pass directly under the first punch 43 of the blanking assembly 4, then, when pulling the metal strip, pass through the upper clamping roller 62 and the lower clamping roller 63 of the second clamping assembly 68, so that the metal strip is fixed by the first clamping assembly 67 and the second clamping assembly 68, the second drive motor 66 is a stepping motor, each time driving the upper clamping roller 62 and the lower clamping roller 63 to rotate, the circumference is equal to the diameter of the metal disc, the second drive motor 66 drives the upper clamping roller 62 and the lower clamping roller 63 to rotate through the third gear 64 and the chain 65, thereby driving the metal strip to move under the first punch 43 of the blanking assembly 4.

[0029] like Figure 1 , Figures 3 to 6 As shown, as a preferred embodiment of the utility model, the positioning assembly 3 is provided with a positioning block 32 that can slide with the positioning groove 31, a third spring 38 is provided on the side of the lower end of the positioning block 32 close to the forming groove 21, one end of the third spring 38 is connected to the side wall of the lower end of the positioning block 32, and the other end of the third spring 38 is connected to the inner side wall of the positioning groove 31 close to the forming groove 21, a permanent magnet 36 is connected to the side of the lower end of the positioning block 32 away from the forming groove 21, and an electromagnet 37 that can attract each other with the permanent magnet 36 is provided on the inner side wall of the positioning groove 31 away from the forming groove 21, a fixing groove 39 and a second annular groove 33 are provided on the top of the positioning block 32, an arc-shaped baffle 34 and a second spring 35 are provided inside the fixing groove 39, and two ends of the second spring 35 are respectively connected to the bottom of the arc-shaped baffle 34 and the bottom of the fixing groove 39, and the second annular groove 33 is arranged at a side of the arc-shaped baffle 34 close to the forming groove 21, and the curvature of the second annular groove 33 is the same as that of the first annular groove 22.

[0030] The blanking assembly 4 includes a first fixed frame 41, a first electric cylinder 42, a first punch 43 and an annular cutter 44. The first fixed frame 41 is connected to the top of the base 1, and the first electric cylinder 42 is arranged on the top of the first fixed frame 41. The telescopic rod end of the first electric cylinder 42 passes through the top of the first fixed frame 41 and is connected to the upper surface of the first punch 43 below the first fixed frame 41. The annular cutter 44 is arranged on the lower surface of the annular cutter 44, and the shape and size of the annular cutter 44 match the circular annular groove formed by the second annular groove 33 and the first annular groove 22.

[0031] The positioning component 3 is used to position and fix the metal disc, so as to increase the stamping accuracy of the stamping component 5. When the punching starts, the turntable 11 rotates 90° counterclockwise to rotate the idle forming component 2 to the bottom of the first punch 43 of the punching component 4. At the same time, the electromagnet 37 is connected to the power supply, and the electromagnet 37 attracts the permanent magnet 36, and drives the positioning block 32 to slide in the direction of the electromagnet 37. When the permanent magnet 36 fits with the electromagnet 37, the second annular groove 33 on the top of the positioning block 32 and the first annular groove 22 on the surface of the forming groove 21 form a circular annular groove. Then, the telescopic rod of the first electric cylinder 42 of the punching component 4 is extended, driving the first punch 43 to descend and approach the surface of the metal strip for cutting. The annular cutter 44 on the lower surface of the head 43 presses down the metal strip and passes through the metal strip. Finally, the annular cutter 44 enters the circular groove formed by the second annular groove 33 and the first annular groove 22, thereby punching out a metal disc on the metal strip. After the punching is completed, the first electric cylinder 42 drives the annular cutter 44 to rise and reset through the first punch 43. At the same time, the fourth spring 46 inside the annular cutter 44 separates the metal disc from the metal strip through the abutment plate 45. At the same time, the cooperation of the fourth spring 46 and the abutment plate 45 can also prevent the metal disc from entering the ring of the annular cutter 44. During cutting, the metal strip will press down the arc baffle 34 and press the arc baffle 34 into the fixed groove 39, thereby preventing the arc baffle 34 from affecting the punching of the metal strip.

[0032] After the punching is completed, the metal disc falls on the top of the forming groove 21, and then the turntable 11 rotates counterclockwise 90° again, rotating the forming component 2 that receives the metal disc to just below the second punch 53 of the stamping component 5. During this process, the downward pressure of the metal belt on the arc baffle 34 disappears, and the arc baffle 34 pops out from the fixing groove 39 through the second spring 35. At the same time, the electromagnet 37 is disconnected from the power supply, and the attraction between the electromagnet 37 and the permanent magnet 36 disappears. The third spring 38 changes from a stretched state to a retracted state. The third spring 38 retracts, driving the positioning block 32 to slide in the positioning groove 31 and move toward the forming groove 21. The positioning block 32 drives the arc baffle 34 to approach the metal disc, and finally abuts against the edge of the metal disc, thereby realizing the positioning and fixation of the metal disc.

[0033] like Figure 1 As shown, as a preferred embodiment of the utility model, the stamping assembly 5 includes a second fixing frame 51, a second electric cylinder 52 and a second punch 53, the second fixing frame 51 is connected to the top of the base 1, the second electric cylinder 52 is arranged on the top of the second fixing frame 51, the telescopic rod end of the second electric cylinder 52 passes through the top of the first fixing frame 41 and is connected to the upper surface of the second punch 53 under the second fixing frame 51, and the second punch 53 matches the shape and size of the forming groove 21.

[0034] The punching assembly 5 is used to punch the metal disc into a bottle cap. The turntable 11 rotates counterclockwise 90° again to rotate the forming assembly 2, which is located directly below the first punch 43 and holds the metal disc, to directly below the second punch 53 of the punching assembly 5. Then, the telescopic rod of the second electric cylinder 52 extends, driving the second punch 53 to move downward and approach the metal disc, and finally punching the metal disc into the forming groove 21 to form a bottle cap. Since the diameter of the metal disc is constantly decreasing during the process of becoming the bottle cap, the third spring 38 is also constantly retracting, driving the arc baffle 34 to always abut against the edge of the metal disc through the positioning block 32, until the metal disc becomes a bottle cap and the positioning block 32 abuts against the side wall of the positioning groove 31 close to the forming groove 21. The arc baffle 34 is now enclosed to form a protective ring, and then the telescopic rod of the second electric cylinder 52 is shortened, driving the second punch 53 to move upward and reset.

[0035] like Figure 5 As shown, as a preferred embodiment of the utility model, the top material assembly 23 includes a top plate 24, a slider 25, a first spring 26 and a slide groove 27, the slider 25 is connected to the left and right sides of the top plate 24, the inner side wall of the molding groove 21 is provided with a slide groove 27 that can slide with the slider 25, and a plurality of first springs 26 are provided inside the molding groove 21, one end of the first spring 26 is fixedly connected to the lower surface of the top plate 24, and the other end of the first spring 26 is fixedly connected to the inner bottom of the molding groove 21.

[0036] The ejecting assembly 23 is used to eject the bottle cap in the molding groove 21. In the previous link, the second punch 53 of the stamping assembly 5 presses the metal disc into the molding groove 21 to turn the metal disc into a bottle cap. When the stamping process is completed, the elastic action of the first spring 26 of the ejecting assembly 23 pushes the top plate 24 upward, thereby driving the slider 25 connected to the top plate 24 to slide in the slide groove 27 of the inner wall of the molding groove 21, increasing the stability of the top plate 24 during the rising process, and also avoiding the possible deviation or tilt when ejecting the bottle cap. As the top plate 24 rises, the bottle cap is gradually pushed toward the opening of the molding groove 21, and finally the formed bottle cap is ejected from the molding groove 21. The protective ring formed by the arc-shaped baffle 34 can protect the bottle cap to a certain extent, preventing the bottle cap from tipping over during the rotation of the turntable 11.

[0037] like Figure 1 As shown, as a preferred embodiment of the utility model, the discharging assembly 7 includes a collecting pipe 71, an air compressor 72, and an injection pipe 73. The air compressor 72 is arranged at the top of the fixed column 13, and the injection pipe 73 is connected to the air compressor 72. The collecting pipe 71 is arranged at a side position opposite to the nozzle of the injection pipe 73 and is connected to the base 1. The nozzle of the injection pipe 73 is arranged above the molding groove 21; a mounting seat 74 is provided between the air compressor 72 and the fixed column 13, the mounting seat 74 is installed on the top of the fixed column 13, and the air compressor 72 is installed in the mounting seat 74.

[0038] The turntable 11 rotates 90° counterclockwise again, driving the bottle caps directly below the second punch 53 to move between the collecting pipe 71 and the jet pipe 73. The air compressor 72 compresses the air to generate a high-speed airflow, and sprays it out through the jet pipe 73, thereby blowing the bottle caps from the forming groove 21 into the collecting pipe 71, making it easier for the operator to collect the processed bottle caps.

[0039] The above is only a preferred embodiment of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
