Description

Technical Field

[0001] This utility model relates to the field of cold-bent steel processing equipment, and more specifically, to a support device for processing high-strength cold-bent steel. Background Technology

[0002] To facilitate movement, the support bases for equipment used in processing high-strength cold-formed steel are mostly designed with casters, and brake pads on the casters are used to restrict their movement, thereby fixing the position of the support base.

[0003] Once the brake pads come loose, the casters can rotate freely. Generally speaking, if the brake pads of one of the four casters come loose, it will accelerate the loosening of the brake pads of the other three casters, eventually leading to a change in the position of the support base, which is not conducive to the processing of cold-formed steel. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the embodiments of this utility model provide a support device for processing high-strength cold-formed steel. The technical problem to be solved by this utility model is: how to reduce and improve the stability when the casters are restricted.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a support device for processing high-strength cold-formed steel, including a support base; a caster wheel, including a shaft frame and a wheel, the shaft frame and the support base being rotatably connected, and the wheel being rotatably connected to the shaft frame; a limiting mechanism including a connecting rod, a lead screw and a threaded sleeve, one end of the connecting rod passing through the shaft frame and the other end being movably connected to the threaded sleeve, the lead screw being internally threaded into the threaded sleeve, the lead screw being rotatably connected to the support base, and the thread between the lead screw and the threaded sleeve being self-locking.

[0006] In a preferred embodiment, there are at least two connecting rods, which are arranged between any two adjacent casters, and the two connecting rods are rotatably connected to the same threaded sleeve.

[0007] In a preferred embodiment, a manual adjustment component is provided on the support base. The manual adjustment component is a polygonal plate fixed to the end of the lead screw, and the manual adjustment component is arranged near the edge of the support base.

[0008] In a preferred embodiment, a manual adjustment component is provided on the support base. The manual adjustment component includes a meshing gear and a rack. The gear and a lead screw are fixedly connected. The gear is located at the bottom center of the support base. A through hole is provided in the support base, and a rack is slidably connected in the through hole.

[0009] In a preferred embodiment, a filler block is inserted into the perforation, and the upper and lower end faces of the filler block are in contact with and adhered to the inner wall of the perforation through anti-slip pads.

[0010] In a preferred embodiment, the combined length of the rack and the filling block is equal to the length of the perforation, and a handle is fixed to the filling block.

[0011] In a preferred embodiment, the handle is positioned above the top surface of the rack.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] This application sets up a limiting mechanism, which uses the rotation of the lead screw and the connecting rod as a medium to drive the corresponding caster wheel to deflect, so that the movable paths of several caster wheels are in different directions, thereby limiting the caster wheels from moving the support base. Moreover, the self-locking characteristic of the thread makes it more stable. Attached Figure Description

[0024] Example 1

[0025] like Figure 1-2 A support device for processing high-strength cold-formed steel includes a support base 1, casters 2, and a limiting mechanism 3.

[0026] The support base 1 is the base body, and its upper surface has threaded holes for loading and unloading molds.

[0027] There are at least four casters 2, which are installed at the four corners of the bottom surface of the support base 1. This embodiment uses four casters as an example. The limiting mechanism 3 is used to limit the rotation of two casters 2 located on any one of the lines.

[0028] The caster wheel 2 includes an axle frame 21 and a wheel 22. The axle frame 21 and the caster wheel base are rotatably connected. The caster wheel base is detachably connected to the four corners of the bottom surface of the support base 1 by bolts and fasteners. The wheel 22 and the axle frame 21 are rotatably connected.

[0029] The limiting mechanism 3 includes a connecting rod 31, a lead screw 32, a screw sleeve 33, and a manual adjustment component 34. When the two wheels 22 remain parallel to each other, the two connecting rods 31 pass through the corresponding shaft brackets 21 respectively. Then, the other end of the connecting rod 31 is movably connected to the screw sleeve 33 through a ball bearing. The lead screw 32 is threaded through the screw sleeve 33. The manual adjustment component 34 is fixed on one end of the lead screw 32 near the outer side of the support base 1, and the other end is rotatably connected to the bottom of the support base 1. The manual adjustment component 34 here is a plate with edges.

[0030] When the manual adjustment component 34 is rotated, the drive screw 32 rotates. At this time, the screw sleeve 33 moves relative to the screw 32. An angle is formed between the two connecting rods 31, which drives the two shaft brackets 21 to deflect relative to each other. At this time, the shaft brackets 21 drive the wheels 22 to deflect as well. The two wheels 22 are in a non-movable position and are naturally locked, which can prevent the connecting rods 31 from moving.

[0031] The lead screw 32 and the threaded sleeve 33 are self-locking.

[0032] Self-locking means that after the manual adjustment component 34 is removed, the screw 32 and the sleeve 33 remain stationary because the thread helix angle is less than the equivalent friction angle of the thread.

[0033] The advantages of this design are:

[0034] Originally, the universal wheels with brake pads were prone to loosening because the brake pads needed to be moved up and down frequently. In this embodiment, the self-locking function can also be achieved through threads, and the threads will not loosen or the probability of the threads loosening is much less than the probability of the brake pads loosening. When the lead screw 32 and the screw sleeve 33 move relative to each other, the connecting rod 31 drives the corresponding wheel 22 to rotate synchronously and symmetrically. At this time, the positions of the two wheels 22 cannot be matched to move the support base 1, so they are equivalent to being limited. Therefore, it can be said that the locking method of this embodiment is superior to the brake pad locking method of the prior art.

[0035] Example 2

[0036] like Figure 1 , Figures 3-6 A support device for processing high-strength cold-formed steel includes a support base 1, casters 2, and a limiting mechanism 3.

[0037] The support base 1 is the base body, and its upper surface has threaded holes for loading and unloading molds.

[0038] There are at least four casters 2, which are installed at the four corners of the bottom surface of the support base 1. This embodiment uses four lockable casters 2 as an example.

[0039] The caster wheel 2 includes an axle frame 21 and a wheel 22. The axle frame 21 and the caster wheel base are rotatably connected. The caster wheel base is detachably connected to the four corners of the bottom surface of the support base 1 by bolts and fasteners. The wheel 22 and the axle frame 21 are rotatably connected.

[0040] The limiting mechanism 3 includes a connecting rod 31, a lead screw 32, a screw sleeve 33, and a manual adjustment component 34. When the two wheels 22 remain parallel to each other, the two connecting rods 31 pass through the corresponding shaft brackets 21 respectively. Then, the other end of the connecting rod 31 is movably connected to the screw sleeve 33 through a ball bearing. The lead screw 32 is threaded through the screw sleeve 33. The manual adjustment component 34 is connected to the lead screw 32 near the center of the bottom of the support base 1. The lead screw 32 and the support base 1 are rotatably connected.

[0041] The manual adjustment component 34 includes a gear 341 and a rack 342. The rotation direction of the two pairs of wheels 22 is controlled by the screw sleeves 33 on both sides of the lead screw 32. The manual adjustment component 34 is located in the middle of the bottom surface of the support base 1. The gear 341 and the lead screw 32 are fixedly connected. A through hole is opened inside the support base 1, and the rack 342 passes through the through hole. The gear 341 and the rack 342 mesh and drive each other. By moving the rack 342 laterally, the rack 342 can be driven to rotate, thereby driving the lead screw 32 to rotate. The rack 342 does not form a squeezing relationship with the through hole.

[0042] The perforation is a T-shaped opening, through which the gear 341 passes and meshes with the horizontally placed rack 342.

[0043] Furthermore, the sidewall of the rack 342 and the sidewall of the perforation are slidably connected by sliding edges and grooves to ensure the smoothness of the rack 342 during movement.

[0044] Furthermore, a filling block 35 is provided on the side of the rack 342. The upper and lower end faces of the filling block 35 abut against the upper and lower inner walls of the perforation. Handles are fixed on both the inner and outer sides of the filling block 35. The handles pass through the top of the rack 342 without interfering with the rack 342. The total length of the rack 342 and the filling block 35 is equal to the total length of the perforation.

[0045] In use, simply insert the filling block 35 into the left or right side of the rack 342 to prevent the gear 341 from resetting.

[0046] Preferably, the lead screw 32 is a double-ended lead screw with opposite threads at both ends. Therefore, when the lead screw 32 rotates, the two threaded sleeves 33 will move closer or further apart, thereby causing the four wheels 22 to change position synchronously, and the wheels 22 on the diagonal will rotate in the same direction.

[0047] This application sets up a limiting mechanism 3, which uses the rotation of the lead screw 32 and the connecting rod 31 as a medium to drive the corresponding caster wheel 2 to deflect, so that the movable paths of several caster wheels 2 are in different directions, thereby limiting the caster wheels 2 from moving the support base 1, and the thread self-locking characteristic has higher stability.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
