DETAILED DESCRIPTION

[0043] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0044] Example 1:

[0045] Reference Figures 1-12, a stamping forming device, including a swivel 1 with a horizontal axis, and support plates 2 are rotatably connected to both sides of the swivel 1. A plurality of stamping grooves 3 are evenly opened on the outer ring of the swivel 1, and each stamping groove 3 includes an outer slot 4 and an inner slot 5; the outer slot 4 is used to receive the rod-shaped material to be stamped, and the inner slot 5 is used to limit the forming shape of the rod-shaped material; a feed hopper 6 is arranged above the swivel 1, the upper half of the feed hopper 6 is expanded, and the lower half of the feed hopper 6 is contracted, and the outlet of the lower half of the feed hopper 6 is close to the stamping groove 3; a stamping assembly is provided on one side of the feed hopper 6, and the stamping assembly includes a No. 1 hydraulic rod 7, and the output end of the No. 1 hydraulic rod 7 is fixedly connected to a stamping plate 8, and the stamping plate 8 includes a stamping head 9 and a pressing plate 10, and the stamping head 9 is used to stamp the rod-shaped material from the outer slot 4 into the inner slot 5, and the pressing plate 10 is used to press the two ends of the rod-shaped material into the inner side of the outer slot 4;

[0046] In the embodiment of the present invention, the swivel 1 can be driven by a motor controlled by an external PLC. The PLC controls the motor, and the motor drives the swivel 1 to rotate intermittently. In this embodiment, since 10 stamping grooves 3 are provided on the outer ring of the swivel 1, the swivel 1 rotates intermittently at an angle of 36 degrees each time.

[0047] In this embodiment, the punching pair is a rod-shaped material with a small volume. The rod-shaped material is generally 8 to 10 cm long and has a diameter of 0.5 to 0.8 cm. The punching pair is shaped as follows: Figure 12 and Figure 13 As shown in , it is specifically assembled on the electronic connector as shown in Figure 6 As shown, the clamping rod 101 is rotated, and the clamping rod 101 is clamped on the electronic connector housing to fasten the two halves of the electronic connector housing together;

[0048] The specific operation of the stamping forming device is as follows:

[0049] Step 1: Prepare the material. Straighten the rolled material and cut it into segments at equal intervals. The rod-shaped material is then placed in the feed hopper 6. The distance between the lower end of the feed hopper 6 and the notch of the punching slot 3 is less than the diameter of the rod-shaped material.

[0050] Step 2: Loading: The rod-shaped material falls into the punching slot 3 under its own gravity. Then, the swivel 1 is driven by the motor to rotate 36 degrees, so that the punching slot 3 holding the rod-shaped material is opposite to the punching assembly.

[0051] Step three, stamping, the No. 1 hydraulic rod 7 is controlled by the external PLC to realize intermittent output and reset of the output end of the No. 1 hydraulic rod 7. When the stamping slot 3 rotates to a position opposite to the stamping plate 8, the stamping plate 8 is squeezed on the rod-shaped material, and the rod-shaped material is squeezed into the stamping slot 3. Specifically, the punch head 9 is squeezed in the middle position of the rod-shaped material, and the rod-shaped material is forced to be pressed into the inner notch 5 and attached to the inner wall of the inner notch 5. At the same time, the end of the rod-shaped material is pressed into the outer notch 4 by the pressing plate 10. At this time, the clamping rod 101 parts can be stamped and formed, and then the No. 1 hydraulic rod 7 drives the stamping plate 8 to withdraw away from the stamping slot 3;

[0052] Step 4: Unloading: the swivel 1 continues to rotate intermittently, driving the stamped card rod 101 component to rotate downward. The card rod 101 component is separated from the stamping groove 3 under its own gravity, thus achieving unloading;

[0053] Then repeat step 1, step 2, step 3 and step 4. The stamping forming device, first of all, in terms of space occupation, the horizontal swivel 1, the loading hopper 6 and the stamping assembly are all arranged above the swivel 1, which takes up less space in the horizontal direction and can save the layout area of the stamping forming device. Then, from the aspects of improving production efficiency and upgrading, such as Figure 5 As shown, multiple stamping and forming devices can be arranged side by side, and the rotating shafts of multiple swivels 1 can be connected together through connectors. The expansion and upgrading operations are relatively simple. A single motor drives multiple swivels 1 to rotate synchronously and intermittently, realizing multi-station synchronous stamping processing, and the efficiency is doubled. Then in terms of cost, the overall volume of the stamping and forming device is small, and the production materials consumed are less, which can reduce the production cost of the device.

[0054] Reference Figures 9-11 The outer ring of the swivel 1 is evenly provided with multiple groups of positioning grooves 11, and the two positioning grooves 11 in each group are arranged on both sides of the stamping groove 3;

[0055] The output end of the No. 1 hydraulic rod 7 is fixedly connected to a connecting plate 12, which is fixed to the stamping plate 8 by a plurality of bolts, and positioning rods 13 are provided on the inner sides of both ends of the connecting plate 12, and the positioning rods 13 are slidably connected to the connecting plate 12 by springs;

[0056] The positioning groove 11 is used to constrain the moving path of the stamping plate 8. When the stamping plate 8 is stamping the rod-shaped material, in order to ensure that the end of the stamping plate 8 can be effectively inserted into the stamping groove 3 and reduce the friction between the surface of the stamping plate 8 and the inner surface of the stamping groove 3, thereby extending the stamping time of the stamping plate 8, specifically, a positioning rod 13 is provided at the end of the connecting plate 12. Each time the stamping plate 8 stamps the rod-shaped material, the end of the positioning rod 13 is inserted into the positioning groove 11. The positioning groove 11 constrains the positioning rod 13, and the positioning rod 13 constrains the moving path of the stamping plate 8, thereby reducing the wear between the stamping plate 8 and the stamping groove 3 and extending the service life of the stamping plate 8.

[0057] Considering the reception of the rod-shaped material by the punching groove 3, the inner wall of the outer groove 4 is matched with the clearance of the rod-shaped material, but it is also necessary to consider the effective punching of the rod-shaped material by the punching plate 8. For this purpose, a recess 35 is set on the outer edge of the punching plate 8. When the punching plate 8 punches the rod-shaped material, the rod-shaped material can be squeezed into the recess 35, and the swing of the rod-shaped material 18 is restrained, so that the rod-shaped material can be placed in the middle position of the punching plate 8, effectively improving the punching effect. At the same time, considering that the punching plate 8 has been used many times, the wear between the punching plate 8 and the rod-shaped material will cause the contour of the punching plate 8 to wear out. For this reason, the punching plate 8 needs to be replaced. For this purpose, the punching plate 8 is set to be fixed on the connecting plate 12 in a detachable manner, which can be flexibly disassembled and replaced.

[0058] Reference Figures 9-11 A through hole 14 is formed between each of the positioning grooves 11 and the outer notch 4. An L-shaped limiting plate 15 is provided in the through hole 14 and the positioning groove 11 connected thereto. One end of the limiting plate 15 is slidably connected in the through hole 14, and the other end of the limiting plate 15 is connected to the inner wall of the positioning groove 11 through a compression spring.

[0059] The inner wall of the outer notch 4 is in clearance with the rod-shaped material, which facilitates the feeding and loading of the rod-shaped material. During the insertion of the positioning rod 13 into the positioning groove 11, the positioning rod 13 squeezes the limiting plate 15, and one end of the limiting plate 15 slides along the through hole 14 and presses against the end of the rod-shaped material, so that the rod-shaped material tends to the middle position of the outer notch 4. When the subsequent stamping plate 8 stamps the rod-shaped material, the ends of the stamped card rod 101 tend to be the same length, which improves the symmetry of the card rod 101 components, that is, produces high-quality products.

[0060] Reference Figure 11-Figure 15 , each of the stamping grooves 3 is provided with a rod-shaped forming die 16, and the forming die 16 is arranged along the inner side wall shape of the stamping groove 3, and the bottom of the forming die 16 is fixed in the stamping groove 3 by multiple bolts;

[0061] Considering that the punching plate 8 will be worn after punching the rod-shaped material many times, the inner surface of the punching groove 3 will also be worn after the punching groove 3 rubs against the rod-shaped material many times, so a detachable punching die is set in the punching groove 3. The punching die cooperates with the punching plate 8 to punch the rod-shaped material. Specifically, the shape of the forming die 16 is as follows: Figure 10 As shown, it is fixed to the bottom of the stamping groove 3 by multiple bolts, which makes it easy to disassemble and replace;

[0062] The detachable and replaceable stamping plate 8 and forming die 16 can also produce card rods 101 of different sizes. According to the size specifications of the card rod 101, the appropriate forming die 16 and stamping plate 8 are specifically assembled, so that the stamping and forming device has higher flexibility and adaptability, and can meet the production of card rods 101 of various specifications.

[0063] Reference Figures 9-11 , a plurality of constraint grooves 17 are evenly provided on the side walls of both sides of the swivel 1, and the constraint grooves 17 are arranged along the edge of the side walls of the swivel 1;

[0064] The two ends of the connecting plate 12 are provided with restraining rods 18, and the punching plate 8 punches the rod-shaped material, and the restraining rods 18 are inserted into the restraining grooves 17;

[0065] The constraint rod 18 and the constraint groove 17 are set, and their cooperation execution purpose is the same as the cooperation execution purpose of the positioning groove 11 and the positioning rod 13, both of which are to further improve the constraint on the stamping plate 8, and the cooperation between the constraint rod 18 and the constraint groove 17 is an auxiliary to the cooperation between the positioning groove 11 and the positioning rod 13; the cooperation between the positioning groove 11 and the positioning rod 13 is the upper limit of the constraint on the stamping plate 8, that is, the cooperation clearance between the positioning rod 13 and the positioning groove 11 is the minimum state gap between the surface of the stamping plate 8 and the inner surface of the stamping groove 3, and the cooperation clearance between the positioning rod 13 and the positioning groove 11 tends to the minimum value, and the cooperation between the constraint rod 18 and the constraint groove 17 is the lower limit of the constraint on the stamping plate 8, that is, the cooperation clearance between the constraint rod 18 and the constraint groove 17 is the maximum state gap between the surface of the stamping plate 8 and the inner surface of the stamping groove 3, and the cooperation between the constraint rod 18 and the constraint groove 17 maintains the lower limit of the constraint of the stamping plate 8, double-layer positioning constraint guarantee.

[0066] Reference Figure 1-Figure 7 ,as well as Figure 16 , an oil replenishing and lubricating assembly is provided on the other side of the feed hopper 6, and the oil replenishing and lubricating assembly includes a fixed plate, a tube body 19 is provided on the fixed plate, and a plurality of nozzles 20 are provided on the tube body 19, and the oil spraying direction of the nozzle 20 is toward the stamping groove 3;

[0067] The tube body 19 is connected to an external oil pump through a hose 21. The external oil pump can inject lubricating oil into the tube body 19 and spray it into the stamping groove 3 from multiple nozzles 20 to reduce the friction between the rod-shaped material and the stamping groove 3 and extend the service life of the stamping plate 8 and the forming mold 16.

[0068] Reference Figure 1-Figure 7 ,as well as Figure 16 The tube body 19 is internally connected to a liquid tube 22 for rotation. The two ends of the liquid tube 22 are connected to the ends of the tube body 19 through torsion springs 23. The ends of the liquid tube 22 are vertically bent and extend toward both sides of the rotating body 1. The liquid tube 22 is provided with a plurality of overflow holes 24, and the overflow holes 24 are opposite to the nozzles 20 one by one.

[0069] The rotating body 1 is provided with levers 25 on both sides. The levers 25 are used to move the vertically bent extension of the liquid tube 22 so that the liquid tube 22 deflects in the tube body 19.

[0070] The vertical bending part of the liquid pipe 22 is connected to the hose 21. The liquid pipe 22 is arranged in the tube body 19. In its initial state, the liquid pipe 22 is under the action of the torsion spring 23 connected to it, and the overflow hole 24 on the liquid pipe 22 is staggered with the nozzle 20. The overflow hole 24 is blocked by the inner wall of the tube body 19. When the swivel 1 rotates, the lever 25 on the swivel 1 will interfere with the extension of the liquid pipe 22, that is, the lever 25 will shift the extension of the liquid pipe 22, causing the liquid pipe 22 to deflect in the tube body 19. At this time, the overflow holes 24 on the liquid pipe 22 are opposite to the nozzle 20 one by one, and the lubricating oil enters the nozzle 20 from the liquid pipe 22 and is sprayed from the nozzle 20 into the stamping groove 3, realizing intermittent spraying supply of lubricating oil, saving lubricating oil, and there is no need to control the start and stop of the external oil pump at all times. The liquid pipe 22 deflects intermittently, accumulates pressure intermittently, and sprays intermittently.

[0071] Reference Figures 9-15 The swivel 1 further has a plurality of cavities 26 formed therein, each of which is provided at the bottom of the stamping groove 3. A top plate 27 is provided in each cavity 26, and a push rod 28 is provided in the middle of the top plate 27. A push plate 29 is fixed to the end of the push rod 28, and the push plate 29 extends into a sliding hole 30 formed in the middle of the forming die 16.

[0072] Each of the cavities 26 extends into the restraining groove 17 , and both ends of each of the top plates 27 extend into the restraining groove 17 and are fixedly connected to the shifting rod 25 ;

[0073] A second hydraulic rod 31 is provided on the inner side wall of the support plate 2. An L-shaped blanking plate 32 is fixed to the end of the second hydraulic rod 31. The blanking plate 32 moves downward to pull the lever 25, and the lever 25 drives the top plate 27 to move downward along the cavity 26.

[0074] The second hydraulic rod 31 is used to blank the card rod 101 parts to be stamped, which is an auxiliary to the blanking of the card rod 101 parts to prevent the card rod 101 parts from failing to effectively separate from the stamping groove 3 and affecting the subsequent stamping process. Specifically, in the initial state, the top plate 27 is away from the forming die 16 under the elastic force of the return spring connected to it. Figure 10 As shown, the top plate 27 is away from the forming die 16 and close to the axis of the swivel 1. When the notch of the stamping groove 3 rotates downward, the lever 25 is located between the two No. 2 hydraulic rods 31. At this time, the No. 2 hydraulic rod 31 is under the control of the external PLC. The No. 2 hydraulic rod 31 drives the blanking plate 32 to move. The blanking plate 32 presses the lever 25 downward, and the lever 25 drives the top plate 27 to move downward. At the same time, the top plate 27 drives the push plate 29 to move through the push rod 28. The push plate 29 moves along the slide hole 30 and presses the card rod 101 components retained in the stamping groove 3 downward, so that the card rod 101 components can smoothly detach from the stamping groove 3.

[0075] Reference Figure 16 The end surface of the vertically bent extension portion of the liquid pipe 22 is threadedly connected with a screw 33;

[0076] The screw 33 is provided to adjust the vertical bending extension of the liquid pipe 22 and adjust the squeezing interference time of the lever 25 on the vertical bending extension of the liquid pipe 22, thereby controlling the lubricating liquid spraying time and the amount of each spray, and flexibly controlling the spray lubrication of the lubricating oil.

[0077] Example 2:

[0078] Reference Figure 13 and Figure 14 , Comparative Example 1: As another embodiment of the present invention, a groove is formed on the surface of the portion of each molding die 16 located at the outer notch 4, and a magnetic block 34 for adsorbing rod-shaped materials is provided in the groove;

[0079] A magnetic block 34 is set in the forming mold 16 to absorb rod-shaped materials, and the forming card rod 101 does not rely on its weight to separate from the stamping groove 3 to achieve the purpose of unloading. The magnetic block 34 absorbs the rod-shaped material and can hang it stably in the stamping groove 3 in advance. When the rotary body 1 rotates subsequently, the rotation speed of the rotary body 1 can be increased, and the efficiency of transferring rod-shaped materials is improved, thereby improving the operating efficiency of the entire device and the production efficiency of the card rod 101 parts. Subsequent unloading is achieved by the cooperation of the No. 2 hydraulic rod 31 and the top plate 27 to achieve detachment and unloading.

[0080] Working principle: Step 1, material preparation, straighten the rolled material and cut it into segments at the same distance, and then the rod-shaped material is processed. Then, the rod-shaped material is placed in the feed hopper 6, and the distance between the lower port of the feed hopper 6 and the notch of the punching slot 3 is less than the diameter of one rod-shaped material;

[0081] Step 2: Loading: The rod-shaped material falls into the punching slot 3 under its own gravity. Then, the swivel 1 is driven by the motor to rotate 36 degrees, so that the punching slot 3 holding the rod-shaped material is opposite to the punching assembly.

[0082] Step three, stamping, the No. 1 hydraulic rod 7 is controlled by the external PLC to realize intermittent output and reset of the output end of the No. 1 hydraulic rod 7. When the stamping slot 3 rotates to a position opposite to the stamping plate 8, the stamping plate 8 is squeezed on the rod-shaped material, and the rod-shaped material is squeezed into the stamping slot 3. Specifically, the punch head 9 is squeezed in the middle position of the rod-shaped material, and the rod-shaped material is forced to be pressed into the inner notch 5 and attached to the inner wall of the inner notch 5. At the same time, the end of the rod-shaped material is pressed into the outer notch 4 by the pressing plate 10. At this time, the clamping rod 101 parts can be stamped and formed, and then the No. 1 hydraulic rod 7 drives the stamping plate 8 to withdraw away from the stamping slot 3;

[0083] Step 4: Unloading: the swivel 1 continues to rotate intermittently, driving the stamped card rod 101 component to rotate downward. The card rod 101 component is separated from the stamping groove 3 under its own gravity, thus achieving unloading;

[0084] Then repeat steps one, two, three and four.
