When the punching die is used, the section 1100 is conveyed to the position below the first stripper plate 300, the upper die plate 100 moves downwards, and the first stripper plate 300 is utilized for punching for the first time; the profile 1100 is moved to the position below the second stripper plate 400, and secondary punching is carried out, the first stripper plate 300 and the second stripper plate 400 are different in distance from the lower die plate 200, the profile 1100 can be subjected to two-section type punching by the aid of the first stripper plate 300 and the second stripper plate 400, the problem of mutual interference caused by the fact that a punching structure needs to be arranged too densely is avoided, meanwhile, punching holes formed by primary punching can assist in secondary punching to carry out accurate positioning, and accordingly quality of punched products is greatly improved.

Referring to fig. 8 and 9, a first elastic member 500 is disposed between the first stripper plate 300 and the upper die plate 100, the first stripper plate 300 is elastically connected to the upper die plate 100 through the first elastic member 500, one end of the first elastic member 500 is fixedly connected to the upper die plate 100, and the other end of the first elastic member 500 is pressed on the first stripper plate 300, so that a first gap 600 is formed between the upper die plate 100 and the first stripper plate 300.

The first and second gaps 600 and 800 are conveniently maintained by the elastic force provided by the first and second elastic members 500 and 700 when not punched.

Preferably, the first and second elastic members 500 and 700 each include a nitrogen spring. The nitrogen spring is a novel elastic component using high-pressure nitrogen as a working medium, has small volume, large elasticity, long stroke, stable work, precise manufacture, long service life, gentle elasticity curve, no need of pre-tightening and the like, has the work which is difficult to finish by conventional elastic components such as metal springs, rubber, air cushions and the like, simplifies the design and manufacture of the die, facilitates the installation and adjustment of the die, prolongs the service life of the die, ensures the stability of the product quality, can also be designed into a nitrogen spring system to participate in the work as a part of the die, can conveniently realize the constant pressure and delayed action in the system, and is a new generation of optimal elastic component with flexible performance.

As shown in fig. 10 and 11, the two sides of the extrusion space 201 are symmetrically provided with the slide guide baffles 202, one end of each slide guide baffle 202 is connected to a limit baffle 203 extending towards the other slide guide baffle 202, the limit baffle 203 is located above the extrusion space 201, an extrusion channel 204 is arranged between the two limit baffles 203, and the extrusion structure 101 extends into the extrusion space 201 through the extrusion channel 204. The sliding guide baffle 202 and the limiting baffle 203 are matched with each other, so that the section 1100 can slide in the extrusion space 201 without being separated. After the section 1100 is punched by the second stripper plate 400, the section 1100 is bent, so that the overall width of the section 1100 is reduced, and the width of the punched section 1100 is smaller than the distance between the two limit baffles 203.

As shown in fig. 8, the extrusion space 201 includes a main space 205 and a deformation-locating space 206 communicating with each other, and the deformation-locating space 206 is recessed toward the inside of the lower mold plate 200.

The positioning plate 207 prevents the profile 1100 from sliding out of the main space 205 too much, which would result in failure to punch.

Preferably, a guide inclined plane 209 is disposed at a side of the deformation positioning space 206 close to the positioning plate 207, and one end of the guide inclined plane 209 is communicated with the bottom surface of the deformation positioning space 206, and the other end is communicated with the bottom surface of the main space 205. After the stamping is completed, an inclined surface which is attached to the guiding inclined surface 209 is formed on the profile 1100, so that when the profile 1100 is pushed, the stamped profile can be separated out of the extrusion space 201 under the guiding action of the inclined surface.

As shown in fig. 1, the profile conveying buffer mechanism 1000 includes a protection frame 1, and further includes a buffer control mechanism 2 disposed at the center of the protection frame 1 and buffer protection mechanisms 3 disposed at two ends of the protection frame 1, the buffer control mechanism 2 and the two buffer protection mechanisms 3 include a buffer protection roller assembly 11 and a buffer protection roller frame set 12 matched with the buffer protection roller assembly 11, and the buffer protection roller assembly 11 is slidably connected to the buffer protection roller frame set 12.

Due to the height limitation of the roller presses 4 and the stamping dies 900, in general, the section 1100 is bent upwards in the air, the section 1100 is arranged between the roller presses 4 and the stamping dies 900, the section 1100 enters the stamping dies 900 through the section, and due to the arrangement of the protection frame 1, the buffer control mechanism 2 and the buffer protection mechanism 3, the section 1100 is guaranteed to be fed under a certain bending radian. On the one hand, in line with existing production practices, and on the other hand, effectively controls the curvature of the profile 1100 to be within a suitable range. In addition, when production fault is suspended, the two ends of the section 1100 are stressed unevenly and fall, and due to the arrangement of the buffer control mechanism 2 and the buffer protection mechanism 3, the height of the section 1100 in the protection frame 1 is almost the same as the height of the section 1100 in the roller press 4 and the stamping die 900, so that the section is effectively protected, and the section is prevented from being scrapped.

Referring to fig. 2 and 4, the buffering protection roller assembly 11 includes a suspension roller 13 and two stroke compression springs 14 respectively disposed at two sides of the suspension roller 13, and the suspension roller 13 and the two stroke compression springs 14 are connected through a transmission rod 15.

In the normal operation process, the profile 1100 passes through the protective frame 1 through the region enclosed by the suspension roller 13 and the two buffer protective roller frames 12, and the profile 1100 can be subjected to speed adjustment and height adjustment in the region enclosed by the suspension roller 13 and the two buffer protective roller frames 12 according to the real-time speed requirement. Thereby effectively offsetting the speed differences of different devices.

Specifically, the suspension roller 13 is provided with a suspension roller shaft 131, the transmission rod 15 is inserted into the suspension roller shaft 131, a suspension roller sliding groove 132 is arranged between the two stroke pressure springs 14, and the suspension roller shaft 131 is slidably connected with the suspension roller sliding groove 132.

When a fault occurs, the device stops, the section 1100 falls to drive the suspension roller 13 to fall along the suspension roller sliding groove 132, the transmission rod 15 drives the two stroke pressure springs 14 to press down, the buffer of the section 1100 in the falling process is realized, and the length of the suspension roller sliding groove 132 is smaller than the limit compression degree of the stroke pressure springs 14.

More specifically, the protection frame 1 is provided with a protection bracket 17 matched with the suspension roller shaft 131, one end of the protection bracket 17 is arranged at one side of the buffer protection roller assembly 11, and one end of the protection bracket 17 is arranged between the two stroke compression springs 14.

In order to prevent the over-compression of the stroke compression spring 14, the protective bracket 17 restricts the further falling of the levitation roller 13 while preventing the accidental falling of the levitation roller sliding groove 132. The floating roller sliding groove 132 also protects the floating roller shaft 131.

It should be understood by those skilled in the art that the protection frame 1 is disposed between the roller press 4 and the stamping die 900, the feeding roller 41 is disposed at one end of the roller press 4 close to the protection frame 1, the feeding roller 51 is disposed at one end of the stamping die 900 close to the protection frame 1, and the height of the buffer protection roller assembly 11 is higher than the heights of the feeding roller 41 and the feeding roller 51. The upward bending in the air of the profile 1100 during the feeding process is achieved by limiting the distance between the roller presses 4 and the stamping die 900. The height of the buffer protection roller assembly 11 is higher than the height of the feeding roller 41 and the feeding roller 51 so as to protect the profile 1100 from being excessively deformed during operation.

Furthermore, both ends of the protection frame 1 are provided with curve adjusting frames 6, the curve adjusting frames 6 comprise curve rollers 61 and adjusting bases 62, and the heights of the two curve adjusting frames 6 are lower than the height of the feeding rollers 41. The profile 1100 passes through the buffer rack through the curve adjustment rack, and further operation according to a certain arc stroke is guaranteed. Meanwhile, for better buffering effect, the height of the curve adjusting frame 6 is lower than that of the feeding roller 41.

Furthermore, the buffering protection roller frame set 12 is composed of two buffering protection roller frames 121 which are oppositely arranged, the suspension roller 13 is arranged between the two buffering protection roller frames 121 and is parallel to the two buffering protection roller frames 121 respectively, the two stroke compression springs 14 are arranged in the two buffering protection roller frames 121 respectively, and an opposite-incidence sensor 133 is arranged between the two buffering protection roller frames 121. The suspension roller 13 is arranged between the two buffer protection roller frames 121, so that the stable operation of the suspension roller 13 is guaranteed to the maximum extent, the deflection of the suspension roller 13 caused by the falling of the section 1100 is avoided, and meanwhile, the stroke pressure spring 14 is arranged in the buffer protection roller frames 121, so that the service life of the stroke pressure spring 14 can be prolonged.

In the embodiment, 3 correlation sensors 133 are arranged, when any one of the correlation sensors 133 detects the bounce of the suspension roller 13, the whole line operation can be stopped immediately, and the safety of the production operation is ensured to the greatest extent by experience.

In order to more efficiently control the operation of the profile 1100, the protection frame 1 comprises a protection top cover 16, and a pause detection sensor 134, a correlation operation sensor 135 and a correlation emergency sensor 136 are sequentially arranged at one end of the buffer control mechanism 2, which is close to the protection top cover 16, from top to bottom.

Wherein, when the section 1100 moves in the range of the pause detection sensor 134 and the correlation operation sensor 135, it is the normal moving range of the section 1100, when the section 1100 is higher than the position of the pause detection sensor 134, the feeding is paused immediately; when the section 1100 is lower than the correlation emergency sensor 136, controlling the punch to stop suddenly; when the fault is cleared, profile 1100 is raised again from a position below correlation emergency sensor 136.

The pause detection sensor 134, the correlation operation sensor 135 and the correlation emergency sensor 136 may be implemented by correlation sensors.

In order to further ensure that the safety of the operation of the profile 1100 is improved, the height of the buffer protection roller assemblies 11 of the protection frame 1 is higher than the height of the buffer protection roller assemblies 11 of the two buffer protection mechanisms 3.

In order to further limit the radian of the profile 1100 and prevent the profile 1100 from being excessively deformed, the bottom surface of the protective top cover 16 is provided with a plurality of protective rollers 161, and the diameter of the protective rollers 161 is not more than one half of the diameter of the floating rollers 13. The protective roller 161 can prevent the profile 1100 from deforming due to direct contact with the protective top cover 16.

The working principle of the invention is as follows: when in use, the section 1100 wound on the storage mechanism 7 is rolled by the roller press 4, and then enters the stamping die 900 through the section conveying buffer mechanism 1000 for stamping. During punching, the section 1100 is conveyed to the position below the first stripper plate 300, the upper template 100 moves downwards, and first punching is performed by using the first stripper plate 300; the section 1100 is continuously conveyed along the slide guide baffle 202 and abutted against the positioning plate 207, and is positioned by using a circular hole formed by first punching in the first step; the upper template 100 moves downwards, the first stripper plate 300 is firstly pressed on the section 1100, and a first punching is carried out on a second section of section; continuously moving the upper template 100 downwards to enable the second stripper plate 400 to be pressed on the first section of the section, performing secondary punching, forming a groove on the first section of the section by matching the forming package insert 102 with the deformation positioning space 206, forming a punching hole on the groove by the extrusion needle 103, and cutting off the tool rest 208 to enable the first section of the section and the second section of the section to be separated from each other; the upper die plate 100 moves upwards, and a second gap 800 is restored between the second stripper plate 400 and the upper die plate 100 under the action of the second elastic piece 700, so that the end part of the extrusion needle 103 is separated from the first section of the section bar; pushing the second section of profile to indirectly push the first section of profile, wherein the first section of profile slides out of the extrusion space 201 under the action of the guide inclined plane 209, and the second section of profile enters the extrusion space 201 instead of the first section of profile; the above steps are repeated to achieve continuous production. And transferring the punched finished product into a storage basket 8 to realize discharging and storage. Under the condition of normal operation, the profile 1100 is subjected to first curve adjustment through the curve rollers 61 of the curve adjusting frame 6 and then enters the protective frame 1, due to the limitation of the equipment height and distance of the roller press 4 and the stamping die 900 and the protective frame 1, the profile 1100 sequentially leaves the protective frame 1 through the buffer control mechanism 2 and the buffer protective mechanism 3 through a certain radian, is subjected to bending adjustment through the curve adjusting frame 6 again, and finally enters the feeding rollers 51 for stamping. When a fault occurs, the section 1100 suddenly stops on the whole line, the buffer protection roller assembly 11 of the buffer control mechanism 2 firstly contacts the section 1100, and the buffer protection roller assembly 11 of the buffer protection mechanism 3 is combined to ensure that the section 1100 stably falls until the height of the section 1100 is approximately consistent with the height of the feeding roller 41 and the height of the feeding roller 51, so that the minimum loss of the section 1100 during the fault is realized. Therefore, the automatic production line is mechanically and automatically controlled from feeding to rolling and then stamping forming, a set of complete automatic production line is formed, the degree of automation is high, the production efficiency is high, stability and reliability are realized, both hands are liberated, and the safety is greatly improved.
