Description

Technical Field

[0001] The utility model relates to the technical field of crank presses, and specifically relates to a crank press for forging tower angle steel fittings. Background Art

[0002] A crank press refers to a press that uses a crank connecting rod as a working mechanism and is the most commonly used cold stamping equipment. When it works, it can use the reciprocating crank connecting rod mechanism to complete repetitive processing operations.

[0003] The patent with the publication number CN216096216U discloses a crank press for forging steel structure power tower angle steel fittings, which includes a forging table, on which a stamping mechanism, a forging mechanism and a positioning mechanism are arranged; the stamping mechanism includes a mounting bracket, two fixing plates, a rotating long rod, a driving gear, a crankshaft and a driven gear. The mounting bracket is fixedly installed on the top of the forging table, the two fixing plates are both fixedly installed on the top of the mounting bracket, the rotating long rod passes through the two fixing plates and is rotatably connected with the two fixing plates. The technical problem solved by the utility model is to provide a crank press for forging steel structure power tower angle steel fittings that can position the angle steel blank directly above the forging die before forging, so that the lengths of both sides of the forged finished product are the same.

[0004] However, in this patent, the working mechanism of the crank press can reciprocate up and down continuously for processing, but the workpiece needs to be manually placed under the crank connecting rod mechanism for processing. Therefore, the crank connecting rod mechanism may cause hand injuries to workers during the up and down movement. For this reason, a new type of crank press is needed to avoid this problem. Summary of the Utility Model

[0005] In order to solve the above technical problems, the utility model proposes a crank press for forging tower angle steel fittings, which can automatically move the workpiece under the crank connecting rod mechanism of the crank press without workers approaching the crank connecting rod mechanism, so that workers will not be at risk of hand injuries during the processing.

[0006] The technical solution for achieving the purpose of the utility model is: a crank press for forging tower angle steel fittings, including a crank press body, on which a crank connecting rod mechanism is arranged, and a processing component is arranged on the crank press body. The processing component includes a support rod, a ring, a first magnet, a turntable, a mold and a second magnet. The support rod is fixedly connected to the crank press body, the ring is fixedly connected to the support rod, the first magnet is fixedly connected to the ring, the turntable is rotatably connected to the ring, a plurality of the molds are fixedly connected to the turntable, a plurality of the second magnets are fixedly connected to the turntable, and a driving component is also arranged on the crank press body.

[0007] Preferably, the processing assembly further includes an annular groove and a roller. The annular groove is formed in the circular ring, the roller is arranged on the turntable, and the roller is in rolling connection with the inside of the annular groove.

[0008] Preferably, the plurality of molds and the plurality of second magnetic blocks are both distributed in an annular array, and the molds and the second magnetic blocks are respectively located at the top and bottom of the turntable.

[0009] Preferably, the driving assembly includes a limiting block, and the plurality of limiting blocks are distributed in an annular array at the bottom of the turntable.

[0010] Preferably, the bottom of the limiting block is beveled, and the limiting blocks correspond to the molds one by one.

[0011] Preferably, the driving assembly further includes a sliding seat, a first connecting rod and a second connecting rod. The sliding seat is slidably connected to the crank press body. The first connecting rod is fixedly connected between the sliding seat and the crank connecting rod mechanism. The second connecting rod is fixedly connected to the sliding seat, and the second connecting rod cooperates with the limiting block.

[0012] Compared with the prior art, the remarkable advantages of the present utility model are:

[0013] Firstly: In the present utility model, workpieces can be sequentially placed into each mold, and then the crank press body is started. After the crank press body is started, the crank connecting rod mechanism thereon will reciprocate up and down, and drive the second connecting rod to move up and down. When the second connecting rod moves downward, it is the stage when the crank connecting rod mechanism moves downward and processes the workpieces in the mold. When the processing is completed and the crank connecting rod mechanism moves upward, it will drive the second connecting rod to move upward. At this time, the second connecting rod will abut against the bevel at the bottom of the limiting block, thereby causing the limiting block to move. The movement of the limiting block will cause the entire turntable to rotate, so that the next mold on the turntable moves below the crank connecting rod mechanism.

[0014] Second: in the present utility model, when the second connecting rod drives the limiting block to move, the next die will not exactly move below the crank connecting rod mechanism. At this time, there is still a small distance between the next die and the exact lower position of the crank connecting rod mechanism. Subsequently, the crank connecting rod mechanism moves downward again. When the second connecting rod disengages from the gap between the two limiting blocks, at this time, the first magnet and the second magnet approach under the action of the suction force, driving the entire turntable to rotate a small distance again, prompting the die corresponding to the second magnet to exactly move below the crank connecting rod mechanism. At the same time, the next limiting block moves above the second connecting rod. Therefore, as the crank connecting rod mechanism reciprocates up and down, the turntable will periodically rotate at a certain angle, so that each die can be sequentially moved below the crank connecting rod mechanism to complete the processing. The whole process is automatic. Workers only need to successively place workpieces into each die without approaching the crank connecting rod mechanism. Therefore, workers will not be at risk of having their hands crushed by the crank connecting rod mechanism. Description of the Drawings

Detailed Embodiment

[0022] The present utility model will be described in detail below. The technical solutions in the embodiments of the present utility model are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] The present utility model provides a crank press for forging tower angle steel fittings through improvement. The technical solution of the present utility model is as follows:

[0024] As Figures 1 - 4 shown, a crank press for forging tower angle steel fittings includes a crank press body 1. A crank connecting rod mechanism 2 is arranged on the crank press body 1. A processing component 3 is arranged on the crank press body 1. The processing component 3 includes a support rod 31, a ring 32, a first magnet 34, a turntable 35, a mold 36 and a second magnet 38. The support rod 31 is fixedly connected to the crank press body 1. The ring 32 is fixedly connected to the support rod 31. The first magnet 34 is fixedly connected to the ring 32. The turntable 35 is rotatably connected to the ring 32. A plurality of molds 36 are fixedly connected to the turntable 35. A plurality of second magnets 38 are fixedly connected to the turntable 35. A driving component 4 is further arranged on the crank press body 1. The second magnet 38 will adsorb to the first magnet 34 during the rotation process. Whenever a second magnet 38 adsorbs to the first magnet 34, exactly one mold 36 is directly below the crank connecting rod mechanism 2.

[0025] Furthermore, the processing component 3 further includes an annular groove 33 and a roller 37. The annular groove 33 is formed on the ring 32. The roller 37 is arranged on the turntable 35. The roller 37 is in rolling connection with the inner wall of the annular groove 33. By using the rotation of the roller 37 and the inner wall of the annular groove 33 to realize the connection between the ring 32 and the turntable 35, the friction force that needs to be overcome during the rotation of the turntable 35 can be reduced.

[0026] Furthermore, a plurality of molds 36 and a plurality of second magnets 38 are both distributed in an annular array. The molds 36 and the second magnets 38 are respectively located at the top and bottom of the turntable 35.

[0027] Furthermore, the driving component 4 includes a limiting block 44. A plurality of limiting blocks 44 are distributed in an annular array at the bottom of the turntable 35. When the second connecting rod 43 moves upward, it will abut against the bottom of the limiting block 44, prompting the limiting block 44 to move and causing the turntable 35 to rotate. However, when only the second connecting rod 43 drives the limiting block 44 to move, the mold 36 cannot be exactly directly below the crank connecting rod mechanism 2. Instead, when the second connecting rod 43 moves downward, through the attraction of the first magnet 34 to the second magnet 38, the mold 36 rotates a small distance again. At this time, the mold 36 will be directly below the crank connecting rod mechanism 2.

[0028] Furthermore, the bottom of the limiting block 44 is beveled, and the limiting blocks 44 correspond to the molds 36 one by one. Since the second connecting rod 43 can only move up and down, in order to enable the turntable 35 to rotate, when the second connecting rod 43 moves downward, the attraction of the first magnet 34 to the second magnet 38 is also required to rotate the turntable 35 by a certain angle, so that the next limiting block 44 can move above the second connecting rod 43.

[0029] Furthermore, the driving assembly 4 further includes a sliding seat 41, a first connecting rod 42 and a second connecting rod 43. The sliding seat 41 is slidably connected to the crank press body 1. The first connecting rod 42 is fixedly connected between the sliding seat 41 and the crank connecting rod mechanism 2. The second connecting rod 43 is fixedly connected to the sliding seat 41, and the second connecting rod 43 cooperates with the limiting block 44.

[0030] The specific working method is as follows: First, the workpieces are sequentially placed into the respective molds 36. Subsequently, the crank press body 1 is started. After the crank press body 1 is started, the crank connecting rod mechanism 2 thereon will reciprocate up and down. At the same time, when the crank connecting rod mechanism 2 moves up and down, it will drive the first connecting rod 42 to move up and down. When the first connecting rod 42 moves up and down, it will drive the sliding seat 41 and the second connecting rod 43 to move up and down. When the second connecting rod 43 moves downward, it is the stage when the crank connecting rod mechanism 2 moves downward and processes the workpiece in the mold 36. When the processing is completed and the crank connecting rod mechanism 2 moves upward, it will drive the second connecting rod 43 to move upward. At this time, the second connecting rod 43 will abut against the bevel at the bottom of the limiting block 44, thereby promoting the movement of the limiting block 44. The movement of the limiting block 44 will cause the entire turntable 35 to rotate, so that the next mold 36 on the turntable 35 moves below the crank connecting rod mechanism 2. However, when the second connecting rod 43 drives the limiting block 44 to move, the next mold 36 will not exactly move below the crank connecting rod mechanism 2. At this time, there is still a small distance between the next mold 36 and the exact lower position of the crank connecting rod mechanism 2. At this time, the crank connecting rod mechanism 2 moves downward again. When the second connecting rod 43 disengages from the gap between the two limiting blocks 44, at this time, the first magnet 34 and the second magnet 38 approach under the action of the suction force, driving the entire turntable 35 to rotate a small distance again, prompting the mold 36 corresponding to the second magnet 38 to exactly move below the crank connecting rod mechanism 2, and at the same time, the next limiting block 44 moves above the second connecting rod 43. Therefore, as the crank connecting rod mechanism 2 reciprocates up and down, the turntable 35 will periodically rotate by a certain angle, so that each mold 36 can be sequentially moved below the crank connecting rod mechanism 2 to complete the processing. The entire process is automatic. Workers only need to continuously place the workpieces into the respective molds 36 without approaching the crank connecting rod mechanism 2. Therefore, workers will not be at risk of having their hands crushed by the crank connecting rod mechanism 2.

[0031] The technical means disclosed by the solution of the present utility model are not limited to those disclosed by the above-mentioned technical means, but also include technical solutions composed of equivalent replacements of the above technical features. Matters not covered by the present utility model belong to the common general knowledge of those skilled in the art.
