Abstract
Description
Technical Field
[0001] This utility model belongs to the field of stamping die technology, and in particular relates to a stamping die with safety protection function. Background Technology
[0002] Stamping dies with safety protection functions achieve operational safety, equipment protection, and risk prevention through a variety of technical means.
[0003] Traditional stamping dies are typically mounted on stamping equipment using bolts. However, with prolonged use, the bolts on the upper die can easily loosen, and due to the die's weight, there is a risk of it falling off. Furthermore, uneven stress can occur during the stamping process, which can lead to bolt breakage and the upper die falling off. When it falls off, it can collide with the lower die, damaging both dies and posing a significant safety risk to nearby workers. Therefore, we propose a stamping die with safety protection features. Utility Model Content
[0004] The purpose of this utility model is to provide a stamping die with a safety protection function. By setting an anti-fall part, specifically, the upper die is inserted into the lifting seat through the top insert block. When the locking block moves above the lifting seat, the locking block pops out by the elastic force of the spring. At this time, the locking block will support the upper die on the lifting seat. When the bolt of the upper die breaks during stamping, the locking block is used to support the upper die to prevent the upper die from falling. This avoids the lower die from colliding and being damaged by the upper die. It solves the problem that traditional stamping dies are usually installed on stamping equipment by bolts, which are prone to loosening and, due to the weight of the die, are prone to falling off. When they fall off, they will collide with the lower die, causing damage to both dies.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0006] This utility model relates to a stamping die with safety protection function, including a stamping machine base, a lower die positioned and installed on the top of the stamping machine base, a top seat installed above the stamping machine base, a hydraulic cylinder installed on the top of the top seat, columns installed at the four corners of the bottom of the hydraulic cylinder, the bottom of the columns being fixedly connected to the top of the stamping machine base, a lifting seat slidably connected to the columns, and an upper die positioned and installed at the bottom of the lifting seat, and further comprising:
[0007] A fall arrestor, wherein the fall arrestor is installed on the top of the upper mold, and the fall arrestor is used to support and limit the movement of the upper mold; and
[0008] A buffer section is installed at the bottom of the lifting seat and is used to absorb the impact force during stamping.
[0009] The hydraulic cylinder output end is fixedly connected to the top of the lifting seat, the hydraulic cylinder is connected to the hydraulic system, and the upper mold is installed on the lifting seat by bolts.
[0010] Furthermore, the fall arrestor includes two insert blocks fixedly connected to the upper mold, the insert blocks being used for positioning the upper mold during installation; and
[0011] A disassembly assembly is mounted on the insertion block and is used to assist in the disassembly of the upper mold.
[0012] The first insertion block is square in shape, and the lifting seat has two square slots, which are inserted into the square slots.
[0013] Furthermore, the front and back sides of the insert block are slidably connected with a locking block, and a spring is fixedly connected to the inner side of the locking block. The other end of the spring is fixedly connected to the inner wall of the insert block. When the upper mold is installed, the locking block will first contact the lifting seat. Since the top of the locking block is set with an incline, the locking block can be pushed smoothly into the insert block.
[0014] The top of the card block is sloped, the bottom of the card block is flat, and the spring is used to spring the card block back to its original position.
[0015] Furthermore, the disassembly assembly includes a U-shaped frame disposed above the first insertion block. The front and back of the locking block are slidably connected to limit rods, and the bottom of the limit rods is fixedly connected to the top of the lifting seat. The U-shaped frame can simultaneously push the two locking blocks on the first insertion block. After the locking blocks are pushed into the first insertion block, the locking blocks will push and squeeze the U-shaped frame under the elastic action of the spring, so that the U-shaped frame is fixed on the outside of the first insertion block, without the need for staff to support the U-shaped frame.
[0016] The limiting rod is used to limit the movement of the U-shaped frame, so that the U-shaped frame moves in a straight line.
[0017] Furthermore, the buffer section includes two fixed blocks fixedly connected to the bottom of the lifting seat, and two damping rods fixedly connected to the bottom. The bottom of each damping rod is fixedly connected to the top of the press base. A second spring is sleeved on the outside of each damping rod. The top of the second spring is fixedly connected to the bottom of the fixed block, and the bottom of the second spring is fixedly connected to the top of the press base. The damping rods and the second spring are used to absorb the impact force simultaneously, reduce the damage caused by excessive force on the mold, alleviate the instantaneous pressure during the stamping process, and extend the service life of the mold.
[0018] Furthermore, a second insert block is slidably connected to the side of the fixed block facing the upper mold. A threaded rod is threadedly connected inside the fixed block, and a throttle is fixedly connected to the outside of the threaded rod. A convex shaft is fixedly connected to the side of the threaded rod facing the second insert block. The threaded rod is rotatably connected to the second insert block through the convex shaft. Slots are provided on both the left and right sides of the upper mold. The convex shaft is used to limit the movement, allowing the threaded rod to smoothly drive the second insert block to move.
[0019] The second insert is used to insert into the slot, the inner diameter of which is larger than that of the second insert. When the threaded rod rotates, it drives the second insert to move through the convex shaft.
[0020] This utility model has the following beneficial effects:
[0021] 1. This utility model incorporates a fall prevention mechanism. Specifically, the upper mold is inserted into the lifting seat via a top insert block. When the locking block moves above the lifting seat, it pops out due to the elastic force of a spring. At this time, the locking block supports the upper mold on the lifting seat. If the bolts of the upper mold break during stamping, the locking block supports the upper mold to prevent it from falling, thereby preventing the lower mold from colliding and being damaged with the upper mold.
[0022] 2. This utility model incorporates a buffer section. Specifically, by rotating the handle clockwise, the second insert block moves from the fixed block to the slot on the upper mold. The second insert block then limits the upper mold, preventing it from falling. The damping rod and spring 2 are used to absorb the impact force simultaneously, reducing damage caused by excessive force on the mold.
[0023] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0033] Please see Figures 1-5 As shown, this utility model is a stamping die with safety protection function, including a stamping machine base 1, a lower die 11 positioned and installed on the top of the stamping machine base 1, a top seat 12 installed above the stamping machine base 1, a hydraulic cylinder 121 installed on the top of the top seat 12, columns 122 installed at the four corners of the bottom of the hydraulic cylinder 121, the bottom of the columns 122 being fixedly connected to the top of the stamping machine base 1, a lifting seat 123 slidably connected to the columns 122, an upper die 124 positioned and installed at the bottom of the lifting seat 123, and further including:
[0034] Fall arrestor 2, installed on top of upper mold 124, serves to support and limit the movement of upper mold 124; and
[0035] The buffer part 3 is installed at the bottom of the lifting seat 123 and is used to absorb the impact force during the stamping process.
[0036] The hydraulic cylinder 121 is fixedly connected to the top of the lifting seat 123 at its output end. The hydraulic cylinder 121 is connected to the hydraulic system. The upper mold 124 is installed on the lifting seat 123 by bolts.
[0037] The fall arrestor 2 includes two insert blocks 21 fixedly connected to the upper mold 124, the insert blocks 21 being used for positioning the upper mold 124 during installation; and
[0038] Disassembly component 22 is installed on insert block 1 21 and is used to assist in the disassembly of upper mold 124.
[0039] Among them, the first insertion block 21 is square, and the lifting seat 123 has two square slots, and the first insertion block 21 is inserted into the square slots.
[0040] Both the front and back of the insert block 21 are slidably connected to the locking block 211. The inner side of the locking block 211 is fixedly connected to the spring 212, and the other end of the spring 212 is fixedly connected to the inner wall of the insert block 21. The upper mold 124 is inserted into the lifting seat 123 through the top insert block 21. When the locking block 211 moves above the lifting seat 123, the locking block 211 pops out by the elastic force of the spring 212. At this time, the locking block 211 will support the upper mold 124 on the lifting seat 123. When the bolt of the upper mold 124 breaks during stamping, the locking block 211 is used to support the upper mold 124 to prevent the upper mold 124 from falling, thereby preventing the lower mold 11 from colliding and being damaged by the upper mold 124.
[0041] The top of the locking block 211 is sloped, the bottom of the locking block 211 is flat, and the spring 212 is used to spring back the locking block 211 to reset.
[0042] The disassembly assembly 22 includes a U-shaped frame 221 set above the insertion block 21. The front and back of the locking block 211 are slidably connected to the limit rod 222, and the bottom of the limit rod 222 is fixedly connected to the top of the lifting seat 123.
[0043] The limiting rod 222 is used to limit the U-shaped frame 221, so that the U-shaped frame 221 moves in a straight line.
[0044] The buffer part 3 includes two fixed blocks 31 fixedly connected to the bottom of the lifting seat 123, and two damping rods 32 fixedly connected to the bottom. The bottom of the two damping rods 32 is fixedly connected to the top of the press base 1. A second spring 321 is sleeved on the outside of the damping rods 32. The top of the second spring 321 is fixedly connected to the bottom of the fixed block 31, and the bottom of the second spring 321 is fixedly connected to the top of the press base 1.
[0045] A second insert block 33 is slidably connected to the side of the fixed block 31 facing the upper mold 124. A threaded rod 331 is threadedly connected inside the fixed block 31. A handle 332 is fixedly connected to the outside of the threaded rod 331. A convex shaft 333 is fixedly connected to the side of the threaded rod 331 facing the second insert block 33. The threaded rod 331 is rotatably connected to the second insert block 33 through the convex shaft 333. Slots 125 are provided on the left and right sides of the upper mold 124. When the handle 332 is rotated clockwise, the second insert block 33 moves from inside the fixed block 31 into the slot 125 on the upper mold 124. The second insert block 33 will limit the upper mold 124 and prevent it from falling. The damping rod 32 and the second spring 321 are used to absorb the impact force at the same time and reduce the damage caused by excessive force on the mold.
[0046] Among them, the second insert 33 is used to insert into the slot 125. The inner diameter of the slot 125 is larger than that of the second insert 33. When the threaded rod 331 rotates, it drives the second insert 33 to move through the convex shaft 333.
[0047] One specific application of this embodiment is:
[0048] In use, first insert the upper mold 124 into the lifting base 123 through the top insert block 21. The locking block 211 will then be pushed into the insert block 21, compressing the spring 212. When the locking block 211 moves above the lifting base 123, it will pop out due to the spring force of the spring 212. At this point, the locking block 211 will support the upper mold 124 on the lifting base 123. Then, use bolts to fix the upper mold 124 to the lifting base 123 to complete the installation. In this method, if the bolts of the upper mold 124 break during stamping, the locking block 211 will support the upper mold 124, preventing it from falling and thus avoiding collision damage between the lower mold 11 and the upper mold 124. Then, turn the handle 332 clockwise. Rod 331 drives the second insert block 33 to move through the cam shaft 333, so that the second insert block 33 moves from the fixed block 31 to the slot 125 on the upper mold 124. Then, stop rotating the handle 332, and the second insert block 33 will limit the upper mold 124 again to prevent the upper mold 124 from falling. When stamping is performed, the hydraulic cylinder 121 is started to drive the lifting seat 123 to move downward, so that the upper mold 124 and the lower mold 11 cooperate to perform stamping. The damping rod 32 and the second spring 321 are used to absorb the impact force at the same time, reduce the damage caused by excessive mold force, relieve the instantaneous pressure during the stamping process, and extend the service life of the mold. The hydraulic cylinder 121 is controlled by the hydraulic system, which includes a power mechanism, a control mechanism, an execution mechanism, and an auxiliary connection mechanism.
[0049] When the upper mold 124 needs to be replaced, first rotate the second insert block 33 counterclockwise to pull the second insert block 33 into the fixing block 31, then remove the bolts fixing the upper mold 124, and then press the U-shaped frame 221 down. The U-shaped frame 221 will slide on the limit rod 222, and after the U-shaped frame 221 contacts the locking block 211, it will push the locking block 211 into the first insert block 21, so that the upper mold 124 can be smoothly disengaged from the lifting seat 123 and the disassembly is completed.
