DETAILED DESCRIPTION

[0057] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0058] It should be noted that the first cross section and the second cross section are parallel to each other.

[0059] As described in the background art, when the plate is broken, the clamp seat may be damaged. The maintenance of the clamp seat is time-consuming and expensive. Therefore, how to extend the service life of the clamp seat has become a technical problem that needs to be solved urgently by those skilled in the art.

[0060] To solve the above problems, refer to Figure 1 , Figure 2 , Figure 3 and Figure 4The present invention provides a broken belt buffer clamping mechanism suitable for a large stretching machine, comprising a clamping seat 110, an upper pad 121, an upper guide groove 131, an upper jaw 141, a lower pad 122, a lower guide groove 132 and a lower jaw 142. The clamping seat 110 is formed with a clamping cavity. The upper pad 121 is detachably mounted on the top of the clamping cavity through an upper connecting assembly 151. The upper guide groove 131 is mounted on the bottom of the upper pad 121 through a first upper elastic member 161. The upper jaw 141 is slidably mounted on the bottom of the upper guide groove 131, and a second upper elastic member 171 capable of abutting against the side wall of the clamping cavity is penetrated inside. The lower pad 122 is detachably mounted on the bottom of the clamping cavity through a lower connecting assembly 152. The lower guide groove 132 is mounted on the top of the lower pad 122 through a first lower elastic member 162. The lower jaw 142 is slidably mounted on the top of the lower guide groove 132, and a second lower elastic member 172 is provided inside the lower jaw 142 so as to abut against the side wall of the clamping cavity. Figure 1As shown, when the sheet material breaks, the upper jaw 141 is subjected to an impact force F1 to the right, which can be decomposed into a first component force F2 obliquely upward and a second component force F3 obliquely downward, and the lower jaw 142 is subjected to an impact force F4 to the right, which can be decomposed into a third component force F5 obliquely downward and a fourth component force F6 obliquely upward. The second component force F3 obliquely downward is first transmitted from the upper jaw 141 to the upper guide groove 131, and the upper guide groove 131 is transmitted to the upper pad 121 through the first upper elastic member 161, and then transmitted from the upper pad 121 to the top of the clamping cavity through the upper connecting assembly 151. In this process, the first upper elastic member 161 can be deformed along its own axial direction to buffer the second component force F3, so as to protect the top of the clamping cavity. The second upper elastic member 171 can be deformed along its own axial direction to buffer the first component force F2 that will act on the side wall of the clamping cavity, so as to protect the side wall of the clamping cavity. The fourth force component F6 which is obliquely upward is first transmitted from the lower jaw 142 to the lower guide groove 132, and the lower guide groove 132 is transmitted to the lower pad 122 through the first lower elastic member 162, and then transmitted from the lower pad 122 to the bottom of the clamping cavity through the lower connecting assembly 152. In this process, the first lower elastic member 162 can deform along its own axial direction to buffer the fourth force component F6, so as to protect the bottom of the clamping cavity. The second lower elastic member 172 can deform along its own axial direction to buffer the third force component F5 which is about to act on the side wall of the clamping cavity, so as to protect the side wall of the clamping cavity. Moreover, the upper pad 121 / lower pad 122 is more conducive to more uniform force transmission to the top / bottom of the clamping cavity, increasing the force conduction area, avoiding excessive local force on the top / bottom of the clamping cavity, and helping to prevent local damage to the top / bottom of the clamping cavity. At the same time, when the upper pad 121 / lower pad 122 is subjected to excessive force, the upper connecting assembly 151 / lower connecting assembly 152 will break before the top / bottom of the clamping cavity is damaged, thereby preventing the clamping cavity from being damaged. Overall, the service life of the clamping seat 110 can be greatly extended, the equipment maintenance cost can be reduced, and the operation rhythm can be guaranteed.

[0061] Preferably, there are a plurality of second upper elastic members 171, which are arranged in pairs. There are a plurality of second lower elastic members 172, which are arranged in pairs.

[0062] Specifically, in the exemplary embodiment, the first upper elastic member 161, the second upper elastic member 171, the first lower elastic member 162 and the second lower elastic member 172 are elastic damping body buffers. Compared with other buffers, under the same stroke and capacity, the elastic damping body buffer has the advantages of large deformation, small reaction force, high energy absorption rate and fast response speed. Moreover, the elastic damping body buffer is small in size, light in weight, compact in structure, easy to install, does not require daily maintenance, and can adapt to various harsh working conditions.

[0063] Specifically, in the example, referring to Figure 1 and Figure 2 , a plurality of upper accommodating holes are formed at the top of the clamping cavity. A plurality of lower accommodating holes are formed at the bottom of the clamping cavity. There are a plurality of first upper elastic members 161, which correspond one-to-one to the plurality of upper accommodating holes. A first upper limit portion 1611 adapted to the upper accommodating hole is provided at the top of each first upper elastic member 161. There are a plurality of first lower elastic members 162, which correspond one-to-one to the plurality of lower accommodating holes. A first lower limit portion adapted to the lower accommodating hole is provided at the bottom end of each first lower elastic member 162. The upper guide groove 131 transmits the force from the upper jaw 141 to the upper pad 121 through the first upper limit portion 1611. The lower guide groove 132 transmits the force from the lower jaw 142 to the lower pad 122 through the first lower limit portion. An upper anti-rotation portion 1612 is provided at the bottom of each first upper elastic member 161 to prevent the first upper elastic member 161 from rotating around its own axis, thereby ensuring better transmission of force. A lower anti-rotation portion is disposed on the top of each first lower elastic member 162 to prevent the first lower elastic member 162 from rotating around its own axis, thereby ensuring better force transmission.

[0064] Preferably, the first upper limit portion 1611 and the second upper limit portion 15121 are square structures or cylindrical structures.

[0065] Preferably, the upper anti-rotation part 1612 includes an upper slotted nut and an upper cotter pin. The upper slotted nut and the upper cotter pin are installed at the bottom of the first upper elastic member 161. The lower anti-rotation part includes a lower slotted nut and a lower cotter pin. The lower slotted nut and the lower cotter pin are installed at the top of the first lower elastic member 162.

[0066] Specifically, in the exemplary embodiment, a plurality of upper threaded holes are formed at the top of the clamping cavity, and correspondingly, a plurality of upper threaded holes are also formed on the upper pad 121. The plurality of upper threaded holes arranged at the top of the clamping cavity are alternately arranged with the plurality of upper accommodating holes. There are a plurality of upper connecting components 151. Each upper connecting component includes an upper threaded sleeve 1511 and an upper bolt 1512. The upper threaded sleeve 1511 is screwed into the upper threaded hole of the clamping cavity. The upper bolt 1512 is screwed into the upper threaded hole of the upper pad 121 and into the upper threaded sleeve 1511. A plurality of lower threaded holes are formed at the bottom of the clamping cavity, and correspondingly, a plurality of lower threaded holes are also formed on the lower pad 122. The plurality of lower threaded holes arranged at the bottom of the clamping cavity are alternately arranged with the plurality of lower accommodating holes. There are a plurality of lower connecting components 152. Each lower connecting component includes a lower threaded sleeve and a lower bolt. The lower threaded sleeve is screwed into the lower threaded hole of the clamping cavity. The lower bolt is screwed into the lower threaded hole and the lower threaded sleeve of the lower pad 122. On the one hand, the upper threaded sleeve 1511 and the upper bolt 1512 cooperate with each other, which is convenient for the disassembly and assembly of the upper pad 121, and the lower threaded sleeve and the lower bolt cooperate with each other, which is convenient for the disassembly and assembly of the lower pad 122; on the other hand, since the outer diameter of the upper threaded sleeve 1511 is larger than the diameter of the cross section of the upper bolt 1512, and the outer diameter of the lower threaded sleeve is larger than the diameter of the cross section of the lower bolt, when the force is too large, the upper bolt 1512 is more likely to break relative to the upper threaded sleeve 1511, and the lower bolt is more likely to break relative to the lower threaded sleeve, thereby preventing the top and bottom of the clamping cavity from being damaged, and effectively extending the service life of the clamping seat 110.

[0067] Specifically, in the example, Figure 2 As shown, a second upper limit portion 15121 is provided at the top of each upper bolt 1512. Each upper connecting assembly 151 also includes an upper disc spring 1513. The upper disc spring 1513 is sleeved on the upper bolt 1512, with the top end abutting against the second upper limit portion 15121, and the bottom end abutting against the upper threaded sleeve 1511. The upper disc spring 1513 can further buffer the second component force F3, thereby enhancing the protective effect on the top of the clamping cavity. A second lower limit portion is provided at the bottom of each lower bolt. Each lower connecting assembly 152 also includes a lower disc spring. The lower disc spring is sleeved on the lower bolt, with the bottom end abutting against the second lower limit portion, and the top end abutting against the lower threaded sleeve. The lower disc spring can further buffer the fourth component force F6, thereby enhancing the protective effect on the bottom of the clamping cavity.

[0068] Specifically, Figure 3As shown, an upper slide rail 1311 is provided at the bottom of the upper guide groove 131. An upper slide groove adapted to the upper slide rail 1311 is provided at the top of the upper jaw 141. The upper slide groove and the upper slide rail 1311 cooperate to effectively improve the smoothness of movement of the upper jaw 141 when the belt is broken. A lower slide rail 1321 is provided at the top of the lower guide groove 132. A lower slide groove adapted to the lower slide rail 1321 is provided at the bottom of the lower jaw 142. The lower slide groove and the lower slide rail 1321 cooperate to effectively improve the smoothness of movement of the lower jaw 142 when the belt is broken.

[0069] Specifically, in the example, Figure 3 As shown, the clamping seat 110 includes a middle base 111, an upper base 112 and a lower base 113. The upper base 112 is fixedly mounted on the upper part of one side of the middle base 111. The lower base 113 is fixedly mounted on the lower part of one side of the middle base 111. A clamping cavity is formed between the lower base 113 and the upper base 112.

[0070] Specifically, in the example, Figure 4 As shown, the upper portion of the clamp seat 110 is formed with an upper rope threading hole, the lower portion is formed with a lower rope threading hole, and the middle portion is provided with an upper clearance hole and a lower clearance hole. The broken belt buffer clamping mechanism suitable for a large stretching machine also includes an upper driving cylinder 181, an upper traction rope 182, a lower driving cylinder 183, a lower traction rope 184, a synchronous hydraulic cylinder 191, a synchronous frame 192, an upper clamping hydraulic cylinder 193, an upper push rod 194, a lower clamping hydraulic cylinder 195 and a lower push rod 196. The axis of the upper driving cylinder 181 is tilted. One end of the upper traction rope 182 is connected to the output shaft of the upper driving cylinder 181, and the other end is connected to the upper jaw 141 after passing through the upper rope threading hole. The upper driving cylinder 181 provides traction for the upper jaw 141 through the upper traction rope 182. The axis of the lower driving cylinder 183 is tilted. One end of the lower traction rope 184 is connected to the output shaft of the lower driving oil cylinder 183, and the other end is connected to the lower jaw 142 after passing through the lower rope hole. The lower driving oil cylinder 183 provides traction for the lower jaw 142 through the lower traction rope 184. The output shaft of the synchronous hydraulic cylinder 191 faces the clamp seat 110. The synchronous frame 192 is fixedly mounted on the output shaft of the synchronous hydraulic cylinder 191 and can move toward or away from the clamp seat 110. The upper clamping hydraulic cylinder 193 is mounted on the upper part of the synchronous frame 192 and can move toward or away from the clamp seat 110 with the synchronous frame 192. One end of the upper push rod 194 is fixedly connected to the output shaft of the upper clamping hydraulic cylinder 193, and the other end can abut against the upper jaw 141 after passing through the upper clearance hole. The lower clamping hydraulic cylinder 195 is mounted on the lower part of the synchronous frame 192 and can move toward or away from the clamp seat 110 with the synchronous frame 192. One end of the lower push rod 196 is fixedly connected to the output shaft of the lower clamping hydraulic cylinder 195 , and the other end thereof can abut against the lower jaw 142 after passing through the lower clearance hole.

[0071] The working process and principle of the broken belt buffer clamping mechanism suitable for large stretching machines are as follows:

[0072] First, the synchronous hydraulic cylinder 191 drives the synchronous frame 192 to move toward the clamping seat 110, so as to drive the upper clamping hydraulic cylinder 193 and the lower clamping hydraulic cylinder 195 to move toward the clamping seat 110, thereby driving the upper push rod 194 to move toward the upper jaw 141, and driving the lower push rod 196 to move toward the lower jaw 142. Next, the upper clamping hydraulic cylinder 193 drives the upper push rod 194 to move leftward to push the upper jaw 141 to move leftward. The lower clamping hydraulic cylinder 195 drives the lower push rod 196 to move leftward to push the lower jaw 142 to move leftward. The upper jaw 141 cooperates with the lower jaw 142 to clamp the plate. Afterwards, the upper clamping hydraulic cylinder 193 drives the upper push rod 194 to move rightward to disengage the upper push rod 194 from the upper jaw 141. The lower clamping hydraulic cylinder 195 drives the lower push rod 196 to move rightward so that the lower push rod 196 is separated from the lower jaw 142. When the sheet material is broken, the first upper elastic member 161 can be deformed along its own axial direction to buffer the second force component F3, so as to protect the top of the clamping cavity. The second upper elastic member 171 can be deformed along its own axial direction to buffer the first force component F2 that will act on the side wall of the clamping cavity, so as to protect the side wall of the clamping cavity. The first lower elastic member 162 can be deformed along its own axial direction to buffer the fourth force component F6, so as to protect the bottom of the clamping cavity. The second lower elastic member 172 can be deformed along its own axial direction to buffer the third force component F5 that will act on the side wall of the clamping cavity, so as to protect the side wall of the clamping cavity. When the upper pad 121 / lower pad 122 is subjected to excessive force, the upper connecting assembly 151 / lower connecting assembly 152 will break before the top / bottom of the clamping cavity is damaged, thereby preventing the clamping cavity from being damaged. Overall, the service life of the clamping seat 110 can be greatly extended, the equipment maintenance cost can be reduced, and the operation rhythm can be guaranteed.

[0073] Preferably, the upper traction rope 182 and the lower traction rope 184 are steel wire ropes with relatively high strength.
