Abstract
Description
Technical Field
[0001] This utility model relates to the field of straightening machine technology, specifically a straightening machine with protective functions. Background Technology
[0002] As a key piece of metal processing equipment, straightening machines play an indispensable role in many industrial fields. In industries such as steel, non-ferrous metals, machinery manufacturing, automobile manufacturing, and aerospace, metal materials often suffer from deformation defects such as bending and twisting after processing such as rolling, forging, and stretching. These defects can seriously affect the quality of metal materials and their subsequent processing performance, leading to problems such as substandard product dimensional accuracy and reduced mechanical properties.
[0003] According to announcement number CN 220111979 U, a channel steel straightening machine includes a straightening machine body. Support plates are fixedly connected to both sides of the bottom of the straightening machine body. Several head bodies are symmetrically arranged on the top of the straightening machine body. A straightening groove is opened on one side of the straightening machine body. An adjustment device is provided on one side of the straightening machine body. The adjustment device includes a baffle. An electric telescopic rod is provided on one side of the baffle. The outer surface of the electric telescopic rod is set on the inner wall of the straightening machine body.
[0004] This device uses a baffle to hold one end of the channel steel against one side. An electric telescopic rod moves the baffle towards one side of the straightening machine body, pushing the channel steel into the rectangular groove. This prevents bent channel steel from failing to pass through the straightening groove and thus ensuring complete straightening. However, during the straightening process, the metal material is subjected to significant stress, which may cause breakage or fragmentation. This results in high-speed ejection of metal fragments and debris. These fragments possess high kinetic energy and, if they hit an operator, could cause serious bodily injury such as cuts, punctures, or crushing wounds, and could even be life-threatening. Utility Model Content
[0005] The purpose of this invention is to provide a straightening machine with protective functions to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a straightening machine with protective function, comprising a straightening machine body, wherein support feet are symmetrically and fixedly connected to the bottom of the straightening machine body in the front, back, left and right directions, and a protective mechanism is provided on the top of the straightening machine body, and a buffer mechanism is provided inside the protective mechanism;
[0007] The protective mechanism includes a fixed frame, which is fixedly connected to the top and back of the straightening machine body. Rotary shafts are rotatably connected to the left and right sides of the inner wall of the fixed frame. Rotary plates are symmetrically fixedly connected to the left and right surfaces of the rotating shafts. Protective frames are fixedly connected to the top of the two rotating plates. Transparent plates are fixedly connected to the surface of the protective frames. An L-plate is fixedly connected to the top of the straightening machine body near the left side of the back. A servo motor is fixedly connected to the back of the L-plate. A worm gear is fixedly connected to the output end of the servo motor. A worm wheel is fixedly connected to the surface of the rotating shaft near the left end.
[0008] Preferably, the inner wall of the fixing frame has holes on the left and right sides that match the rotating shaft, and the rotating shaft surface passes through and is rotatably connected to the holes.
[0009] Preferably, the protective frame has grooves on both the left and right sides to facilitate the movement of the workpiece within the grooves and to facilitate straightening work.
[0010] Preferably, the worm gear meshes with a worm wheel.
[0011] Preferably, the buffer mechanism includes a first fixing plate, which is symmetrically fixedly connected to the left and right sides of the protective frame near the bottom front. Guide rods are symmetrically arranged on the top of the two first fixing plates. A limit ring is fixedly connected to the surface of the guide rod near the top. A second fixing plate is fixedly connected to the surface of the guide rod near the bottom. A spring is sleeved between the first and second fixing plates on the surface of the guide rod. A rubber pad is fixedly connected to the bottom of the guide rod.
[0012] Preferably, the top of the first fixing plate has a hole that matches the guide rod, and the guide rod is slidably connected to the hole through the surface of the guide rod.
[0013] Preferably, the top end of the spring is fixedly connected to the bottom of the first fixed plate, the bottom end of the spring is fixedly connected to the top of the second fixed plate, and the rubber pad is in contact with the top of the straightening machine body near the front.
[0014] Compared with the prior art, this utility model provides a straightening machine with protective function, which has the following beneficial effects:
[0015] 1. This straightening machine with protective functions features a protective frame and transparent plate in its protective mechanism that effectively shields the working area of the straightening machine, preventing workpieces from popping out due to force during the straightening process and causing safety hazards. At the same time, the transparent plate does not affect the operator's observation of the internal working conditions, ensuring operational safety and visibility. The servo motor drives the worm gear, worm wheel, and rotating shaft to rotate, and the opening and closing of the protective frame can be flexibly controlled. This facilitates the loading and unloading of workpieces when needed and can also be closed in time during operation to form protection. The automated control method improves the convenience of operation.
[0016] 2. This protective straightening machine features a buffer mechanism that, through the coordinated action of a first fixed plate, guide rod, limit ring, second fixed plate, spring, and rubber pad, provides excellent cushioning and shock absorption for the protective frame during closing. When the protective frame rotates downwards and approaches the top of the straightening machine body, the rubber pad first contacts the straightening machine body, providing initial cushioning. Subsequently, the spring is compressed, further absorbing and dispersing the impact force, preventing a rigid collision between the protective frame and the straightening machine body. This protects both the protective frame and the straightening machine body from damage and extends the service life of the equipment. Attached Figure Description

[0025] This utility model provides the following technical solution:
[0026] Example 1
[0027] Please see Figure 1-3 This utility model provides a technical solution: a straightening machine with protective function, including a straightening machine body 1, with support feet 2 symmetrically fixedly connected to the bottom of the straightening machine body 1 in the front, back, left and right directions, and a protective mechanism 3 provided on the top of the straightening machine body 1, with a buffer mechanism 4 provided inside the protective mechanism 3;
[0028] The protective mechanism 3 includes a fixed frame 31, which is fixedly connected to the top and back of the straightening machine body 1. Rotating shafts 32 are rotatably connected to the left and right sides of the inner wall of the fixed frame 31. Rotating plates 33 are symmetrically fixedly connected to the surface of the rotating shafts 32. Protective frames 34 are fixedly connected to the top of the two rotating plates 33. Transparent plates 35 are fixedly connected to the surface of the protective frames 34. An L-plate 36 is fixedly connected to the top of the straightening machine body 1 near the left side of the back. A servo motor 37 is fixedly connected to the back of the L-plate 36. A worm gear 38 is fixedly connected to the output end of the servo motor 37. A worm wheel 39 is fixedly connected to the surface of the rotating shaft 32 near the left end.
[0029] The inner wall of the fixed bracket 31 has holes on the left and right sides that match the rotating shaft 32, and the rotating shaft 32 passes through and is rotatably connected to the hole.
[0030] The protective frame 34 has grooves on both the left and right sides to facilitate the movement of the workpiece within the grooves and to facilitate straightening work.
[0031] The worm 38 meshes with the worm wheel 39.
[0032] Example 2
[0033] Please see Figure 4 Furthermore, based on Example 1, a buffer mechanism 4 is obtained.
[0034] The buffer mechanism 4 includes a first fixing plate 41, which is symmetrically fixedly connected to the left and right sides of the protective frame 34 near the bottom front. Guide rods 42 are symmetrically arranged on the top of the two first fixing plates 41. A limit ring 43 is fixedly connected to the surface of the guide rod 42 near the top. A second fixing plate 44 is fixedly connected to the surface of the guide rod 42 near the bottom. A spring 45 is sleeved between the first fixing plate 41 and the second fixing plate 44 on the surface of the guide rod 42. A rubber pad 46 is fixedly connected to the bottom of the guide rod 42.
[0035] The top of the first fixing plate 41 has a hole that matches the guide rod 42, and the guide rod 42 passes through the surface and slides up and down in the hole.
[0036] The top end of the spring 45 is fixedly connected to the bottom of the first fixed plate 41, and the bottom end of the spring 45 is fixedly connected to the top of the second fixed plate 44. The rubber pad 46 is in contact with the top of the straightening machine body 1 near the front.
[0037] In actual operation, when this device is in use, an L-plate 36 is fixedly connected to the top of the straightening machine body 1 near the left side of the back. A servo motor 37 is fixedly connected to the back of the L-plate 36. A worm gear 38 is fixedly connected to the output end of the servo motor 37. A worm wheel 39 is fixedly connected to the surface of the rotating shaft 32 near the left end, and the worm gear 38 meshes with the worm wheel 39. When it is necessary to open the protective frame 34 for workpiece loading and unloading operations, the servo motor 37 is started. The servo motor 37 drives the worm gear 38 to rotate. Since the worm gear 38 meshes with the worm wheel 39, the rotation of the worm gear 38 will drive the worm wheel 39 to rotate, thereby driving the rotating shaft 32 to rotate. The rotation of the rotating shaft 32 causes the rotating plate 33 and the protective frame 34 to lift upward, realizing the opening of the protective frame 34. When the operation is completed and the protective frame 34 needs to be closed, the servo motor 37 is controlled to rotate in the reverse direction, the worm gear 38 drives the worm wheel 39 in the reverse direction, causing the shaft 32 to rotate in the reverse direction. The protective frame 34 then rotates downwards and finally covers the working area on the top of the straightening machine body 1, providing protection. The protective frame 34 has slots on the left and right sides. This design is to facilitate the movement of the workpiece in the slots. During the straightening process, the workpiece can smoothly enter the straightening area of the straightening machine through these slots and move out of the slots after straightening is completed without being obstructed by the protective frame 34, ensuring the continuity and smoothness of the straightening work. A transparent plate 35 is fixedly connected to the surface of the protective frame 34, which allows the operator to observe the working conditions inside the straightening machine.
[0038] As the protective frame 34 rotates downwards under the drive of the servo motor 37 and approaches the top of the straightener body 1, the rubber pad 46 first makes near-frontal contact with the top of the straightener body 1. The rubber pad 46, with its elasticity and softness, can absorb some of the impact force upon contact, providing initial cushioning. As the protective frame 34 continues to move downwards, the guide rod 42 slides upwards within the hole of the first fixing plate 41, and the second fixing plate 44 compresses the spring 45. During compression, the spring 45 generates a spring force opposite to the compression direction. This spring force further absorbs and disperses the impact force of the protective frame 34 as it descends, thereby reducing the collision force between the protective frame 34 and the straightener body 1, preventing damage to both the protective frame 34 and the straightener body 1 due to rigid collisions, and extending the service life of the equipment.
