At the same time, after stamping is completed, the waste slag cannot be directly discharged, and it is necessary to manually remove the waste slag, which is time-consuming and laborious, and accidents are likely to occur during the operation, and the safety is not high. Summary of the Invention

[0005] The utility model provides an efficient stamping device for high-rise fire doors, aiming to solve the problems that when the stamping device is in use, it cannot clamp and fasten the stamping workpiece, resulting in the displacement of the workpiece during the operation, which may cause accidental injury to the staff. At the same time, after stamping is completed, the waste slag cannot be directly discharged, and it is necessary to manually remove the waste slag, which is time-consuming and laborious, and accidents are likely to occur during the operation, and the safety is not high.

[0006] An embodiment of the utility model provides an efficient stamping device for high-rise fire doors, including a support frame. A support table is installed on the support frame. A pushing mechanism is arranged on the support frame. A first hydraulic cylinder is installed at the top of the support frame. The output end of the first hydraulic cylinder is fixedly connected to a lower pressing plate. A base is installed at the bottom of the lower pressing plate. A punch is connected to the base. A clamping and fastening mechanism is further arranged at the bottom of the lower pressing plate.

[0007] Further, the pusher mechanism includes a through - opening formed in the support frame, which is arranged facing the support table. A second hydraulic cylinder is installed in the through - opening, and a push plate is installed at the output end of the second hydraulic cylinder.

[0008] By adopting the above - mentioned technical solution, after the punch has finished stamping the workpiece, the second hydraulic cylinder can push towards the waste slag until the push plate pushes the waste slag off the support table, avoiding the process of manually removing the waste slag, saving time and effort, and preventing accidental injuries to the staff due to operation errors, thus greatly improving safety.

[0009] Further, the clamping and fastening mechanism includes two fixed columns fixedly connected to the bottom of the lower pressing plate. The two fixed columns are respectively located on both sides of the base. A sliding groove is formed in the fixed column, and a sliding plate is slidably connected in the sliding groove. One end of the sliding plate is connected to the bottom of the sliding groove through a first spring, and the other end of the sliding plate is fixedly connected to a push rod. The push rod extends outside the sliding groove and is fixedly connected to a sliding block at the end.

[0010] By adopting the above - mentioned technical solution, when the lower pressing plate presses down until the clamping block contacts the workpiece, the push rod will slide upward in the sliding groove of the fixed column and compress the first spring. When the lower pressing plate rises, the first spring can reset and rebound.

[0011] Further, the clamping and fastening mechanism further includes a clamping block below the fixed column. A sliding track is provided on the surface of the clamping block, and a cavity is formed inside the clamping block. A guide rod is fixedly connected in the cavity. The sliding block is slidably connected to the guide rod. A second spring is connected between the bottom of the cavity at the end far from the support table and the sliding block, and the second spring is sleeved outside the guide rod.

[0012] By adopting the above - mentioned technical solution, the sliding block can slide on the guide rod in the cavity. At the same time, under the continuous downward push of the lower pressing plate and the push rod, the sliding block can squeeze the second spring. When the lower pressing plate rises, the second spring can reset and rebound.

[0013] Further, the surface of the clamping block facing the support table is right - angled and fits with the edge of the support table.

[0014] By adopting the above - mentioned technical solution, the clamping block can better fit with the support table.

[0015] Further, the surface of the fixed column opposite to the clamping block is wedge - shaped and they match each other.

[0016] By adopting the above technical solution, when the fixing column is attached to the surface opposite to the clamping block, the fixing column can continue to move along the clamping block of the wedge surface, so that the two clamping blocks move synchronously inward relative to each other under the action of the fixing column to clamp the workpiece.

[0017] The beneficial effects of the present utility model are as follows:

[0018] 1. By setting the material pushing mechanism in the present utility model, after the punch has finished stamping the workpiece, the second hydraulic cylinder can push towards the waste slag until the push plate pushes the waste slag away from the support table, avoiding the process of manually removing the waste slag, saving time and effort, and not causing accidental injury to the staff due to operation errors, greatly improving safety.

[0019] 2. By setting the clamping and fastening mechanism in the present utility model, when the lower pressing plate presses down until the clamping block contacts the workpiece, the push rod will slide upward in the chute of the fixing column and compress the first spring. At the same time, under the continuous downward push of the lower pressing plate and the push rod, since the surface of the fixing column opposite to the clamping block is wedge-shaped, the fixing column can continue to move along the clamping block of the wedge surface, enabling the sliding block to slide on the guide rod in the cavity and squeeze the second spring, so that the two clamping blocks move synchronously relative to the support table under the action of the fixing column to clamp the workpiece, avoiding the displacement of the workpiece during the operation and accidentally injuring the staff.

Specific embodiments

[0028] In order to make the objectives, technical solutions and advantages of the technical solutions of the present utility model clearer, the technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings of specific embodiments of the present utility model. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0029] Referring to Figure 1 , Figure 2 , an efficient stamping device for high-rise fire doors according to an embodiment of the present utility model is proposed, which includes a support frame 1, a support table 2 is installed on the support frame 1, a material pushing mechanism 3 is arranged on the support frame 1, the material pushing mechanism 3 includes a through port 31 opened on the support frame 1, the through port 31 is arranged opposite to the support table 2, a second hydraulic cylinder 32 is installed in the through port 31, and a push plate 33 is installed at the output end of the second hydraulic cylinder 32. After the punch 7 has completed stamping on the workpiece, the second hydraulic cylinder 32 can push towards the waste slag until the push plate 33 pushes the waste slag away from the support table 2, avoiding the process of manually removing the waste slag, saving time and effort, and not causing accidental injuries to the staff due to operation errors, greatly improving safety.

[0030] Referring to Figure 1 , Figure 3 , Figure 4 , Figure 5, a first hydraulic cylinder 4 is installed on the top of the support frame 1. The output end of the first hydraulic cylinder 4 is fixedly connected with a lower pressing plate 5. A base 6 is installed at the bottom of the lower pressing plate 5. A punch 7 is connected to the base 6. A clamping and fastening mechanism 8 is also arranged at the bottom of the lower pressing plate 5. The clamping and fastening mechanism 8 includes two fixed columns 81 fixedly connected to the bottom of the lower pressing plate 5. The two fixed columns 81 are respectively located on both sides of the base 6. A chute is opened in the fixed column 81. A sliding plate 82 is slidably connected in the chute. One end of the sliding plate 82 is connected with the bottom of the chute through a first spring 89. The other end of the sliding plate 82 is fixedly connected with a push rod 83. The push rod 83 extends outside the chute and is fixedly connected with a sliding block 84 at the end. The clamping and fastening mechanism 8 also includes a clamping block 85 below the fixed column 81. A slideway 87 is arranged on the surface of the clamping block 85. A cavity 86 is opened inside the clamping block 85. A guide rod 88 is fixedly connected in the cavity 86. The sliding block 84 is slidably connected with the guide rod 88. A second spring 810 is connected between the bottom of the cavity 86 at the end far from the support table 2 and the sliding block 84. The second spring 810 is sleeved outside the guide rod 88. The surface of the clamping block 85 opposite to the support table 2 is right-angled and fits with the edge of the support table 2, so that the clamping block 85 can better fit with the support table 2. The surface of the fixed column 81 opposite to the clamping block 85 is wedge-shaped and matches with each other. When the lower pressing plate 5 is pressed down until the clamping block 85 contacts the workpiece, the push rod 83 will slide upward in the chute of the fixed column 81 and compress the first spring 89. At the same time, under the continuous downward pushing of the lower pressing plate 5 and the push rod 83, the sliding block 84 can slide on the guide rod 88 in the cavity 86. Because the surface of the fixed column 81 opposite to the clamping block 85 is wedge-shaped, when the fixed column 81 fits with the surface of the clamping block 85 opposite to it, the fixed column 81 continues to slide along the wedge surface of the clamping block 85. Then the sliding block 84 can squeeze the second spring 810 in the cavity 86, so that the two clamping blocks 85 move relatively towards the support table 2 under the action of the fixed column 81 to clamp the workpiece. When the lower pressing plate 5 is lifted, the first spring 89 and the second spring 810 can reset and rebound, so that every time the first hydraulic cylinder 4 descends to punch the workpiece, the workpiece can be automatically clamped and fastened first and then punched under the action of the clamping block 85 and the push rod 83. After the punching is completed, under the action of the first spring 89 and the second spring 810, the clamping block 85 and the push rod 83 can also reset and loosen the clamping and fastening of the workpiece.

[0031] The specific implementation method is as follows: When in use, when it is necessary to punch a workpiece, place the workpiece on the support table 2, start the machine, and the first hydraulic cylinder 4 presses down, and then the lower pressure plate 5 presses down. When the lower pressure plate 5 presses down until the clamping block 85 contacts the workpiece, the push rod 83 will slide upward in the chute of the fixed column 81 under the continuous pressing of the lower pressure plate 5, and compress the first spring 89. When the opposite surfaces of the fixed column 81 and the clamping block 85 are in contact, the push rod 83 will stop compressing the first spring 89. At the same time, under the continuous downward action, the fixed column 81 will continue to slide downward along the inclined surface of the clamping block 85. In the case where the fixed column 81 cannot slide left and right, the two fixed columns 81 will synchronously squeeze the two clamping blocks 85 towards the support table 2, causing the two clamping blocks 85 to slide synchronously towards the support table 2 to clamp and fasten the workpiece. At the same time, the sliding block 84 will compress the second spring 810 along the guide rod 88 until the punch 7 completes the punching of the workpiece. When the punching is completed, the first hydraulic cylinder 4 retracts, the lower pressure plate 5 rises, and the first spring 89 and the second spring 810 reset and rebound. Then, the push rod 83 and the clamping block 85 can reset under the action of the first spring 89 and the second spring 810, waiting to clamp and fasten the workpiece during the next punching. After clamping and fastening the workpiece, it can prevent the workpiece from shifting during the punching process, preventing accidental injury to the staff. At the same time, the second hydraulic cylinder 32 will advance, causing the push plate 33 to push the waste slag on the support table 2 away from the support table 2, avoiding the process of manually removing the waste slag, saving time and effort, and not causing accidental injury to the staff due to operation errors, greatly improving safety.
