Description

Technical Field

[0001] The present invention relates to the field of stamping technology, and more specifically, to a mechanical stamping device. Background Art

[0002] Stamping is a metal processing method based on the plastic deformation of metal. It uses molds and stamping equipment to apply pressure to the sheet material to cause plastic deformation or separation of the sheet material, thereby obtaining parts with certain shapes, sizes and properties. Compared with castings and forgings, stamping parts are thin, uniform, light and strong. Stamping can produce workpieces with reinforcing ribs, ribs, undulations or flanging that are difficult to manufacture by other methods to improve their rigidity.

[0003] Mechanical stamping equipment is a forming processing method that uses a press and a mold to apply external force to plates, strips, pipes and profiles to cause plastic deformation or separation, thereby obtaining workpieces of the desired shape and size. The working principle of mechanical stamping equipment is mainly to convert the rotational motion of the motor into the linear reciprocating motion of the slider through a crank-connecting rod mechanism to form the blank. Its basic working elements include stamping power, male and female molds and the raw materials of the product. The machine tool drives the opening and closing of the male and female molds under the action of the stamping power, thereby cutting, punching, stretching and other shaping processes of the raw materials between them. This process is the operating principle of the stamping machine tool. Mechanical stamping equipment is widely used in many industries such as automobiles, ships, aerospace, electronics, and home appliances. With the continuous advancement of science and technology and the continuous development of industry, stamping equipment is also constantly improving and innovating to meet the needs of more efficient, smarter, more flexible and more environmentally friendly industrial production.

[0004] There are large-scale stamping equipment and small-scale stamping equipment. Large-scale stamping equipment usually uses a press to apply pressure. Some small-scale stamping equipment relies on simple manpower stamping, and some rely on hydraulic push rods to apply pressure. Most of the current small-scale stamping equipment relies on manual placement and removal of stamped parts. Since stamping is a repetitive and highly dangerous job, long-term repeated feeding and retrieving actions can easily cause operator fatigue and inattention. When the slider moves downward, the operator's limbs are still in the danger zone and are easily crushed by the rapidly descending slider, thereby increasing the risk of operating errors and injuries.

The two ends of each slide groove 207 are aligned, and the middle part of the two slide grooves 207 is higher than the two ends, which is used to facilitate the first support arm 204 and the second support arm 205 to be misaligned when they meet. The two slide grooves 207 are respectively slidably installed with pulleys 208, which are used to achieve that when the pulleys 208 slide in the slide grooves 207, the first support arm 204 and the second support arm 205 can be misaligned when they meet. The two pulleys 208 are respectively connected to the first support arm 204 and the second support arm 205;

[0041] A connecting rod 209 is installed on each of the two sliders 203, which is used to realize the function of transmitting the two sliders 203. Each connecting rod 209 passes through the base 201 and can slide on the base 201;

[0042] A motor 210 is installed on the base 201, which is used to provide power, and a rotating wheel 211 is rotatably installed at one end of the base 201 away from the motor 210. The output end of the motor 210 is plugged with a rotating wheel 211, which is used to realize the rotation of the transmission belt 212. The two rotating wheels 211 are flush with each other, which is used to ensure that the transmission belt 212 is in a horizontal position, and a transmission belt 212 is installed between the two rotating wheels 211, which is used to realize the transmission of the connecting rod 209. The two connecting rods 209 are respectively connected to the two sides of the transmission belt 212, so as to enable the first support arm 204 and the second support arm 205 to alternately enter the molding cavity 6.

[0043] The base 201 is provided with an ejector assembly 7, which is used to move the completed workpiece toward the ejector rod 706 through the first support arm 204 and the second support arm 205. When the ejector rod 706 passes through the cross plate 702, it will be pressed down. When the ejector rod 706 moves into the inside of the support frame 705, it will compress the spring 707. Then, when the ejector rod 706 separates from the cross plate 702 and enters the sliding hole 701 opened on the first support arm 204 or the second support arm 205, the spring 707 will reset the ejector rod 706 through its resilience. At this time, the ejector rod 706 will have a The ejector assembly 7 is used to eject the workpiece formed in the mold frame 206 out of the mold frame 206 by the elastic force of the ejector rod 706, so as to automatically eject the workpiece formed in the mold frame 206, and can effectively and quickly push the formed workpiece out of the mold, which can effectively reduce the downtime caused by manually removing the workpiece, help speed up the production rhythm, improve the overall production efficiency, and avoid the number of times that workers directly contact high-temperature or heavy workpieces, thereby reducing labor intensity and potential safety risks.

[0044] The ejection assembly 7 includes a slide hole 701. The first support arm 204 and the second support arm 205 are provided with slide holes 701 at positions corresponding to the mold frame 206, which are used to facilitate ejection of the workpiece formed in the mold frame 206 through the ejector rod 706. Each slide hole 701 penetrates the corresponding mold frame 206.

[0045] The lower ends of the first support arm 204 and the second support arm 205 are both installed with a transverse plate 702, and both ends of the two transverse plates 702 are in a smooth curved shape, which is used to facilitate the function of pressing the top rod 706 downward, and one end of the two transverse plates 702 close to the sliding hole 701 extends into the sliding hole 701;

[0046] A leakage opening 703 is provided through the base 201, which is used to convey the ejected workpiece into the conveying pipe 803. A support rod 704 is installed in the leakage opening 703, which is used to connect the support frame 705. The support rod 704 is cylindrical, which is used to prevent the ejected workpiece from falling on the support rod 704. A support frame 705 is installed on the support rod 704, which is used to ensure the sliding stability of the ejector rod 706. The ejector rod 706 is slidably installed in the support frame 705, which is used to eject the completed workpiece. A spring 707 is connected between the ejector rod 706 and the support frame 705, which is used to compress the spring 707, and then make the ejector rod 706 have elastic force through the resilience of the spring 707, so as to eject the completed workpiece out of the mold frame 206.

[0047] Both sides of the push rod 706 are set to smooth inclined surfaces 708, which are used to reduce the friction between the push rod 706 and the contact surface of the cross plate 702 during the sliding process when the push rod 706 passes through the cross plate 702. This design helps the push rod 706 to move downward more smoothly, and the top of the push rod 706 is set to a smooth curved surface 709, which is used to reduce the friction resistance of the push rod 706 when it slides on the cross plate 702. The end of the push rod 706 away from the base 201 can enter any mold frame 206, which is used to enable the push rod 706 to accurately eject the workpiece formed in the mold frame 206.

[0048] A conveying assembly 8 is provided on the base 201, which is used to realize that when the ejector rod 706 ejects the finished workpiece of the underwear from the mold frame 206, the finished workpiece will be separated from the mold frame 206 and fall into the baffle 801. When the finished workpiece falls on the baffle 801, it will fall from the baffle 801 to the leakage 703, and then fall from the leakage 703 to the conveying pipe 803, and then fall directly from the conveying pipe 803 into the storage box 804. When the finished workpiece passes through the baffle 801, the conveying pipe 803 and the storage box 804, the protective pad 802 of the baffle 801, the conveying pipe 803 and the storage box 804 will play a buffering role, so as to automatically convey the finished workpiece to the storage box 804, which can effectively avoid manual intervention, thereby greatly improving production efficiency.

[0049] The conveying assembly 8 includes a baffle 801, a baffle 801 is installed at the upper end of the base 201 and at the leak 703, which is used to ensure that the ejected workpiece can slide into the leak 703, and a conveying pipe 803 is installed at the lower end of the base 201 and at the leak 703, which is used to ensure that the ejected workpiece can accurately fall into the storage box 804 through the conveying pipe 803, and a storage box 804 is slidably installed on the bottom plate 1 and between the bases 201, and the conveying pipe 803 and the storage box 804 correspond to each other, which are used to collect the workpieces;

[0050] Protection pads 802 are installed in the baffle plate 801, the delivery tube 803 and the storage box 804, which are used to prevent the tool from directly contacting the baffle plate 801, the delivery tube 803 and the storage box 804 when it falls, so as to protect the tool and reduce the impact force when the tool falls;

[0051] The baffle 801 is outwardly expanded to cover a wider area so that the workpieces can fall into the designated collection area more accurately.

[0052] A cleaning assembly 9 is provided on the base 201, which is used to realize that when the finished workpiece is separated from the mold frame 206, the air compressor 902 on the connecting arm 901 will spray air into the mold frame 206, so as to clean the iron filings in the mold frame 206, which can effectively improve product quality and extend the life of the mold;

[0053] The cleaning assembly 9 includes a connecting arm 901, and the connecting arm 901 is installed on the base 201, which is used to support the air compressor 902. The air compressor 902 is installed on the connecting arm 901. When any mold frame 206 is closest to the air compressor 902, the air compressor 902 is located at the upper end of the mold frame 206 and corresponds to the mold frame 206, which is used to achieve accurate cleaning of the mold frame 206.

[0054] Clamps 11 are symmetrically installed on the first support arm 204 and the second support arm 205 at the mold frame 206, which are used to clamp the mold frame 206. A bolt 11 is installed on each of the clamps 10, and each of the bolts 11 passes through the clamp 10 and extends to the corresponding first support arm 204 or second support arm 205, which is used for moving the clamp 10, and is used to facilitate the replacement of mold frames 206 of different shapes, so as to achieve diversity.

[0055] The mold frame 206 on the first support arm 204 and the second support arm 205 can both slide in the molding cavity 6 , which is used to accurately deliver the mold frame 206 into the molding cavity 6 .

[0056] Working principle: When a workpiece needs to be punched, the operator first places the workpiece to be punched in the mold frame 206 on the second support arm 205, and then starts the motor 210 to rotate the connected rotating wheel 211. At this time, when the rotating wheel 211 rotates, the transmission belt 212 rotates, and when the transmission belt 212 rotates, the other rotating wheel 211 rotates, which is used to move the two connected connecting rods 209 one forward and one backward at the same time;

[0057] When the transmission belt 212 rotates, the two connected connecting rods 209 will move forward and backward at the same time. At this time, the connecting rod 209 on the first support arm 204 will move backward, and the connecting rod 209 on the second support arm 205 will move forward. When the connecting rod 209 on the first support arm 204 moves backward, the connected slider 203 will slide backward on the slide rail 202 at the same time. At the same time, when the connecting rod 209 on the second support arm 205 moves forward, the connected slider 203 will move forward on the slide rail 202. When the slider 203 on the first support arm 204 moves backward, it will move the first support arm 204 backward. When the slider 203 on the second support arm 205 moves forward, it will move the second support arm 205 forward, so as to realize the alternating movement of the first support arm 204 and the second support arm 205.

[0058] At the same time, when the first support arm 204 moves backward, it will bring the connected pulley 208 to move backward in the slide groove 207. At this time, the pulley 208 connected to the first support arm 204 will slide from a low end of the slide groove 207 to the high point of the middle section of the slide groove 207. At this time, the first support arm 204 will move backward on the slider 203, and then the pulley 208 will move from the high point of the middle section to the other low end of the slide groove 207. At this time, the first support arm 204 will return to its original position. At this time, the mold frame 206 on the first support arm 204 will be at the initial position of the mold frame 206 on the second support arm 205, so that the position of the first support arm 204 can be adjusted when the first support arm 204 moves.

[0059] Similarly, when the second support arm 205 moves forward, the connected pulley 208 will slide from one lower end of the slide slot 207 to the middle height of the slide slot 207, and then the pulley 208 will slide from the middle height of the slide slot 207 to the other lower end of the slide slot 207, so as to adjust the position of the second support arm 205 when the second support arm 205 moves;

[0060] At this time, the mold frame 206 on the second support arm 205 will be located at the position of the mold frame 206 on the first support arm 204, and is also in the molding cavity 6 and corresponds to the punch head 5, for punching the workpiece in the mold frame 206;

[0061] At this time, the first support arm 204 and the second support arm 205 will complete the position exchange, and the motor 210 will stop at this time, and then the workpiece to be stamped is placed on the mold frame 206 on the first support arm 204. When the workpiece in the mold frame 206 on the second support arm 205 is stamped, the motor 210 will be started again, and then the first support arm 204 and the second support arm 205 will be exchanged again in the above manner, so as to achieve alternating loading;

[0062] When the second support arm 205 returns to the position of the first support arm 204 with the stamped workpiece, it will pass through the push rod 706. At this time, the smooth inclined surface 708 of the push rod 706 will contact the smooth arc surface at one end of the horizontal plate 702. Then, when the second support arm 205 continues to move backward, the push rod 706 will pass through the smooth arc surface and reach the plane of the horizontal plate 702, so as to move the push rod 706 into the support frame 705.

[0063] At this time, the ejector rod 706 will be squeezed and moved in the support frame 705, and the movement of the ejector rod 706 will compress the connected spring 707. Then, when the second support arm 205 continues to move backward, the ejector rod 706 will enter the sliding hole 701 through another smooth arc surface of the cross plate 702. At this time, the spring 707 will reset the ejector rod 706 through its resilience. At this time, the ejector rod will have elastic force. When the ejector rod 706 is reset, it will directly come to the mold frame 206 and eject the workpiece presented in the mold frame 206. At this time, the molded workpiece will be separated from the mold frame 206, so that the ejector rod 706 can move upward to eject the molding mold.

[0064] Then, a new workpiece to be punched is placed on the mold frame 206 on the second support arm 205. Then, when the second support arm 205 moves forward again, the smooth inclined surface 708 of the ejector pin 706 will contact the smooth arc surface of one end of the horizontal plate 702 first. When the second support arm 205 continues to move forward, the smooth arc surface on the horizontal plate 702 presses down on the ejector pin 706, so that the ejector pin 706 moves into the support frame 705 and compresses the spring 707 at the same time, until the ejector pin 706 is pressed. When the ejector pin 706 is completely separated from the slide hole 701 and comes to the plane of the horizontal plate 702, and then when the ejector pin 706 is separated from the horizontal plate 702, the spring 707 will push the ejector pin 706 back to its original position by means of resilience, and when the first support arm 204 moves toward the ejector pin 706, the ejector pin 706 will eject the completed workpiece in the mold frame 206 on the first support arm 204 in the above manner, thereby achieving automatic ejection of the completed workpiece in the mold frame 206;

[0065] After the ejector rod 706 ejects the finished underwear workpiece from the mold frame 206, the finished workpiece will be separated from the mold frame 206 and fall into the baffle 801. After the finished workpiece falls onto the baffle 801, it will fall from the baffle 801 to the leak 703, and then fall from the leak 703 to the conveying pipe 803, and then directly fall from the conveying pipe 803 into the storage box 804. When the finished workpiece passes through the baffle 801, the conveying pipe 803 and the storage box 804, the baffle 801, the conveying pipe 803 and the protective pad 802 of the storage box 804 will play a buffering role, so as to automatically convey the finished workpiece into the storage box 804.

[0066] At the same time, when the finished workpiece is separated from the mold frame 206 , the air compressor 902 on the connecting arm 901 will spray air into the mold frame 206 to clean the iron filings in the mold frame 206 .
