Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of auxiliary equipment for metal sheet cutting and processing, specifically a material unloading support device for a thin shearing machine. Background Technology
[0002] In the thin-shearing process of sheet metal, when the width difference between the upper and lower reels is large (especially when the width of a single side of the reel is ≤500mm), the reel is prone to skewing on one side when placed on the unloading trolley, making normal unloading impossible. Simultaneously, this skewing causes indentation defects on one side of the reel due to pressure from the tilt, leading to reel degradation and affecting product quality. Previously, to address these issues, companies typically used support devices to support the reel.
[0003] However, the existing support devices are generally adjusted by bolts / nuts, which require the use of wrenches and other auxiliary tools when adjusting the height, making the operation very inconvenient and affecting the unloading efficiency of the thin shear machine. Utility Model Content
[0004] The first technical problem this utility model aims to solve is to provide a material unloading support device for a thin shearing machine, which adopts a "pull-out lifting rod + gear rack" structure, eliminating the need for auxiliary tools such as wrenches, thereby solving the problems of inconvenient operation and low unloading efficiency when adjusting the height of the support device.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: A thin shearing machine unloading support device includes a horizontally arranged base, a positioning cylinder vertically fixed to the top of the base, a horizontally arranged top seat, and a lifting cylinder vertically fixed to the bottom of the top seat and capable of moving up and down within the positioning cylinder. Its core improvement lies in the fact that: a positioning sleeve and a rotating sleeve that extend laterally and are coaxially arranged are fixed on the left and right outer side walls of the positioning cylinder, and a lifting rod is assembled inside the positioning sleeve and the rotating sleeve. The positioning cylinder is equipped with a gear that is coaxially mounted with the lifting rod and can rotate with the lifting rod. A gear rack that meshes with the gear is vertically fixed inside the lifting cylinder. When the lifting rod is pulled out of the positioning sleeve, it can be rotated, and the height of the lifting cylinder can be adjusted by rotating the lifting rod; when the lifting rod is inserted into the positioning sleeve, the lifting rod is restricted from rotating by the positioning sleeve, and the lifting cylinder is completely fixed.
[0006] By adopting the above solution, the support device uses a "pull-out lifting rod + gear rack" structure, which eliminates the need for auxiliary tools such as wrenches. The lifting rod can be pulled out from the positioning sleeve to rotate and adjust the height. After insertion, the rotation is restricted and fixed by the positioning sleeve, making the operation more convenient and improving the unloading efficiency of the thin shearing machine.
[0007] As a preferred embodiment of the unloading support device for a thin shearing machine, a clearance groove is provided on both the left and right side walls of the lifting cylinder, wherein the lifting rod is located in the clearance groove to avoid the lifting rod interfering with the up and down movement of the lifting cylinder.
[0008] As a preferred embodiment of the unloading support device for a thin shearing machine, two vertically arranged limiting blocks are fixed inside the positioning cylinder, and the gear is placed between the two limiting blocks to prevent the gear from moving along the axial direction of the lifting rod; a vertically arranged clearance groove is provided inside the lifting cylinder, and both limiting blocks are located in the clearance groove to prevent the lifting rod from interfering with the up and down movement of the lifting cylinder.
[0009] In a preferred embodiment of a thin shearing machine unloading support device, the lifting rod is divided into a left section, a middle section, and a right section. Both the left and middle sections of the shaft are fixed with limiting ribs; the left section of the shaft engages with the internal positioning sleeve through its limiting ribs (cross-shaped), and the middle section of the shaft engages with the internal gear through its limiting ribs (straight-legged). The surface of the right section of the shaft is smooth, and the right section of the shaft rotates with the inside of the swivel sleeve.
[0010] The first technical problem this invention aims to solve is to provide a material unloading support device for a thin shearing machine, which solves the problem of wear on the roll shaft caused by the top seat by adding two sets of rotating support wheels to support the roll shaft.
[0011] To achieve the above objectives, the present invention adopts the following technical solution: Based on the above scheme, two symmetrical brackets are fixed on the upper surface of the top seat. Each bracket is rotatably mounted with a support wheel to support the roller and reduce the friction between the two.
[0012] The beneficial effects of this utility model are: 1. Convenient operation and improved unloading efficiency: Adopting a "pull-out lifting rod + gear rack" structure, no auxiliary tools such as wrenches are required. The lifting rod can be rotated and adjusted by pulling it out from the positioning sleeve. After insertion, the rotation is restricted and fixed by the positioning sleeve, making the operation more convenient.
[0013] 2. Improve unloading efficiency: Quick adjustment and reliable fixation reduce downtime and improve the unloading efficiency and output of the thin shear. Attached Figure Description

[0018] Example 1, as Figures 1 to 2 As shown, a thin shearing machine unloading support device includes a horizontally arranged base 1, a positioning cylinder 2 vertically welded and fixed to the top of the base 1, a horizontally arranged top seat 3, and a lifting cylinder 4 vertically welded and fixed to the bottom of the top seat 3 and capable of moving up and down within the positioning cylinder 2.
[0019] Continue as Figures 1 to 2 As shown, a positioning sleeve 5 and a rotating sleeve 6 that extend laterally and are coaxially arranged are welded and fixed on the left and right outer side walls of the positioning cylinder 2, respectively. A lifting rod 7 (with a handle) is assembled inside the positioning sleeve 5 and the rotating sleeve 6.
[0020] like Figures 4 to 5 As shown, clearance grooves 8 are provided on both the left and right side walls of the lifting cylinder 4, and the lifting rod 7 is located in the clearance grooves 8 to prevent the lifting rod 7 from interfering with the up and down movement of the lifting cylinder 4.
[0021] like Figure 6 As shown, the boom 7 is divided into a left boom 71, a middle boom 72 and a right boom 73. Limiting ribs are welded and fixed on both the left section 71 and the middle section 72; the left section 71 is in a limiting engagement with the inside of the positioning sleeve 5 through its limiting rib, which is the cross-shaped limiting rib 74; the middle section 72 is in a limiting engagement with the inside of the gear 9 through its limiting rib, which is the straight limiting rib 75. The surface of the right section of the shaft 73 is smooth, and the right section of the shaft 73 rotates with the inside of the rotating sleeve 6.
[0022] like Figure 3 As shown, a gear 9 is installed inside the positioning cylinder 2, which is coaxially assembled with the lifting rod 7 and can rotate with the lifting rod 7. A gear rack 10 that meshes with the gear 9 is vertically welded and fixed inside the lifting cylinder 4.
[0023] Continue as Figure 3 As shown, two vertically arranged limiting blocks 11 are welded and fixed inside the positioning cylinder 2. The gear 9 is placed between the two limiting blocks 11 to prevent the gear 9 from moving axially along the lifting rod 7.
[0024] Continue as Figure 3 As shown, a vertically arranged clearance groove 12 is provided inside the lifting cylinder 4, and two limiting blocks 11 are located inside the clearance groove 12 to prevent the lifting rod 7 from interfering with the up and down movement of the lifting cylinder 4.
[0025] like Figures 4 to 5 As shown, when the lifting rod 7 is pulled out from the positioning sleeve 5, the lifting rod 7 can be rotated, and the height of the lifting cylinder 4 can be adjusted by rotating the lifting rod 7; when the lifting rod 7 is inserted into the positioning sleeve 5, the lifting rod 7 is restricted from rotating by the positioning sleeve 5, and the lifting cylinder 4 is completely fixed.
[0026] Working principle of Example 1: Placement: The base 1 is placed longitudinally on the unloading station of the thin shearing machine, and the roll is supported by the top seat 3.
[0027] Height adjustment process: Pull out the lifting rod 7 until the left section of the rod 71 is completely disengaged from the positioning sleeve 5, as follows. Figure 4 As shown; rotating lifting rod 7: the cross-shaped limiting rib 74 of the left section of the rod 71 rotates with the lifting rod 7, and drives the gear 9 to rotate synchronously through the straight limiting rib 75 of the middle section of the rod 72; the gear 9 meshes with the gear rack 10 inside the lifting cylinder 4, driving the lifting cylinder 4 to move up and down along the positioning cylinder 2 until the target height is reached; the lifting rod 7 is pushed in towards the positioning sleeve 5, so that the cross-shaped limiting rib 74 of the left section of the rod 71 re-engages with the positioning sleeve 5 for limiting, at which point the lifting rod 7 cannot rotate, and the lifting cylinder 4 is fixed, as shown. Figure 5 As shown.
[0028] Example 2, as Figure 7 As shown, the only difference between this embodiment and Embodiment 1 is that, based on Embodiment 1, two mutually symmetrical brackets 13 are fixed on the upper surface of the top seat 3. Each bracket 13 is rotatably mounted with a support wheel 14 to support the scroll and reduce the friction between the two.
[0029] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model.
