Abstract

The utility model provides a bent bar blocking device which comprises a guide sleeve used for inserting and limiting a bar; the lifter is used for driving the guide sleeve to lift and adjust the height; the spring realizes elastic connection of the guide sleeve; and the guide sleeve is mounted at the top of the elevator in a clamping manner, so that quick disassembly and assembly are realized. The lifter is used for adjusting the height of the guide sleeve to be concentric with the bar; and when the bending degree or the size deviation of the bar is large, the bar is blocked by the guide sleeve, so that the damage to detection equipment is avoided. And due to the arrangement of the spring, the guide sleeve is elastically connected, and when the bar collides with the guide sleeve, the guide sleeve can deviate for buffering, so that the damage to the guide sleeve caused by collision is reduced.

Description

Technical Field

[0001] The utility model relates to the technical field of steel rolling, in particular to a bending bar blocking device. Background Art

[0002] After the bars are rolled, they will bend, so they will be straightened first, and then non-destructive testing will be performed to determine whether the material is qualified.

[0003] Due to the limited straightening capacity of the straightening machine, there will still be bars with large curvature or large dimensional deviation, especially at the head and tail ends of the bars. When such bars with poor straightening effect are subjected to line flaw detection, the bars with large curvature or large dimensional deviation will damage the equipment.

[0004] Therefore, how to overcome the above-mentioned defects has become a problem to be solved urgently by those skilled in the art. Utility Model Content

[0005] In order to solve the technical problems in the background technology, the utility model discloses a bent bar blocking device.

[0006] The utility model provides a bent bar material blocking device, comprising:

[0007] Guide sleeve, used for limiting the insertion of rods;

[0008] A lifter, used to drive the guide sleeve to move up and down to adjust its height;

[0009] Spring, to achieve elastic connection of the guide sleeve;

[0010] The guide sleeve is installed on the top of the lift by snap-fitting, which enables quick disassembly and assembly.

[0011] The lift is used to adjust the height of the guide sleeve so that it is concentric with the rod; when the rod has a large curvature or dimensional deviation, the rod will be blocked by the guide sleeve to avoid damage to the testing equipment. The setting of the spring makes the guide sleeve elastically connected. When the rod hits the guide sleeve, the guide sleeve will deviate and buffer, thereby reducing the damage caused by the collision to the guide sleeve.

[0012] In order to improve the position stability of the guide sleeve, further improvements are: the elevator is a four-linked screw elevator, and a support plate is installed at the top driving end; the guide sleeve is installed on the upper end of the support plate through a spring.

[0013] The specific structure of the guide sleeve clamping is: the upper end of the support plate is connected with a clamping seat through a spring, and a clamping slot is arranged on the clamping seat; both ends of the guide sleeve are provided with clamping plates, which are clamped in the clamping slot.

[0014] In order to improve the position stability of the guide sleeve clamping, a further design is that the clamping plate and the slot wall of the clamping slot are provided with a penetrating plug hole, and a latch is installed in the plug hole.

[0015] The state of the spring directly affects the stability of the guide sleeve. Based on this, a further design is that the coils of the spring are arranged closely in sequence. This arrangement not only makes the guide sleeve elastic, but also improves the supporting strength of the spring, making the position of the guide sleeve more stable.

[0022] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0023] Embodiment 1:

[0024] like Figure 1-4 As shown, the utility model discloses a bent bar blocking device, including a chassis, in which a lift 2 is installed. The lift 2 is a four-linked screw lift, and a support plate 4 is installed at the driving end of the upper end.

[0025] The upper end of the support plate 4 is connected to a holder 5 through four symmetrically arranged springs 3. The upper end of the holder 5 is clamped with a guide sleeve 1, and its specific structure is as follows: two symmetrically arranged slots 6 are provided on the holder 5. Square clamping plates 7 are provided at both ends of the guide sleeve 1, which are clamped in the slots 6 to achieve quick disassembly and assembly of the guide sleeve 1. The shape of the clamping plate 7 makes it contact with the bottom surface of the slot 6, and the position is more stable. The slot wall of the clamping plate 7 and the slot 6 is provided with a through plug hole 8, and a latch 9 is installed in the plug hole 8 to improve the stability of the installation structure of the guide sleeve 1.

[0026] The guide sleeve 1 is used to limit the insertion of the rod; the elevator 2 is used to adjust the height of the guide sleeve 1 so that it is concentric with the rod; when the curvature or size deviation of the rod is large, the rod will be blocked by the clamping plate 7 to avoid damage to the detection equipment. The setting of the spring 3 makes the guide sleeve 1 elastically connected. When the rod hits the guide sleeve 1, the guide sleeve 1 will deviate and buffer, thereby reducing the damage to the guide sleeve 1 caused by the collision.

[0027] Embodiment 2:

[0028] Compared with the first embodiment, the difference is that the coils of the spring 3 are arranged closely in sequence. Such an arrangement not only makes the guide sleeve 1 elastic, but also improves the support strength of the spring 3 and the position stability of the guide sleeve 1.

[0029] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without deviating from the technical concept of the utility model through the above description. The technical scope of the utility model is not limited to the content of the specification, and its technical scope must be determined according to the scope of the claims.
