Abstract

The utility model relates to a pipe expanding and rivet head combination tool which is suitable for pipe expanding and a rivet head of a metal pipe head, and belongs to the technical field of auxiliary tools matched with electrical tools. At least three roller shafts are arranged on a machine frame, and each roller shaft is provided with a roller with high hardness. When the tool is used, under the power of the electrical tools, the rotary rollers expand and roll up along net pipe heads to bring back draft of the pipe heads; big heads and small heads of the end portions of net pipes in a framework are formed; by means of control of adjusting pieces through a surface bearing, the purpose that the big heads and the small heads are suitable for pipes with big diameters and pipes with small diameters is achieved; and each roller shaft is fixed in the machine frame through fixing pieces, and a special tool for the pipe expanding and the rivet head is formed. The tool is simple and applicable in structure, and is beneficial for effective reinforcement of the net pipes; and the ends of the net pipes cannot easily fall off from holes in the framework through force exerting or a pry bar, and therefore the anti-theft effect is improved.

Description

Expanding rivet head assembly tool

Technical field

The utility model relates to a combination expander rivet tools for the metal tube and nozzle expansion rivet head ,belonging to the auxiliary tool technology field, which is working with power tool.

Background technology

The dwelling house in town and country uses the room for the safety of the person and property with some now, burglary-resisting window take stainless steel tube as main material all has been installed, these burglary-resisting windows are take the stainless steel square tube as framework, weld up and down some square tube reinforcements in framework, some webmasters of horizontally set, each root webmaster all passes corresponding hole on framework and reinforcement, and the industry and commerce that adds that has is carried out the spot welding reinforcing at webmaster and corresponding aperture.But in the application of reality, often cannot stand and steal firmly repeatedly pulling of people, an end webmaster will break away from the hole on framework, forms macroscopic void, thereby has lost antitheft effect.

Summary of the invention

The utility model is designed to provide a combination of pipe expansion rivet tool for strengthening the network security windows, security windows due to address existing network management framework and reinforcement through corresponding holes, only in NM and the corresponding orifice spot welding reinforcement, the presence of people forced to stand up to repeated theft pull and pry bars, one end of the network will be out of the holes on the frame, the formation of large pores, thus losing the security role of the defect by the utility model with the appropriate power tool to achieve an effective network reinforcement, in addition to the implementation of the shear, the difficult through force or pry bar from the frame on the network side of the hole, thereby enhancing the security effect.

The utility model is intended to achieve the following technical solutions A combination expander rivet tools from the rack, roller shafts, rollers, adjusting nut and the bearing form; rack center section was dry shaped structure; Rack front-end and back-end small disc between large disc fixed at least three equally spaced radial roller shaft; axis of each wheel in turn sets set wheel, wheel bearings and connecting screwing the adjusting nut; wheel size of the head ends of the structure was connecting bearing the bulk of the inner end of the arc with a concave edge.

Being radial fixing roller shaft and the angle of frame central axle is 5-10 °.

One end of roller shaft is placed in the corresponding hole of roundel, and the other end is placed in the respective aperture of big disk and fixes through bolt.

Bearing adopts plane bearing, and the moving limit in plane bearing and an end of roller are fixed.

The diameter of roundel is 20-22 ㎜.

The diameter of big disk is 30-32 ㎜.

The axial length of roller is 15-25 ㎜.

The utility model in a rack provided with at least three roller shaft,, High hardness of each wheel shaft assembly, when used, the electric power of the tool, the rotary roller along the ferrule extend up along the network turn VOL,, Prompted tube head produces backwards pull,, formed network ends in the frame size of the head,, By plane bearing after adjusting member control, meet the applicable size diameter pipe purpose, each roller shaft through fixed fastening in a rack, , the formation of both flaring and rivet special tools.This practical new construction is simply applicable, is conducive to effective reinforcing of webmaster, be difficult to by firmly or the thick stick sled make the webmaster end break away from hole on framework, thereby improve antitheft effect.

The specific embodiment

Further illustrate in conjunction with the accompanying drawings and embodiments the utility model, as shown in Figure 1, the utility model is by frame 1, roller shaft 2, and roller 3, adjusting nut 4 and bearing 5 consist of; The central cross-section of frame 1 is dried font structure; At least be radial equi-spaced apart between the roundel of frame 1 front end and the big disk of rear end and fix three roller shafts 2; Be nested with successively bearing 5 and the adjusting nut 4 that spins of roller 3, connection roller 3 on each roller shaft 2; The two ends of roller 3 are the concentric reducer structure, the arc limit that major part the inner of connection bearing 5 has indent; One end of roller shaft 2 is placed in the corresponding hole of roundel, and it is fixing through bolt 6 that the other end is placed in the respective aperture of big disk; Bearing 5 adopts plane bearing, and the moving limit in plane bearing and an end of roller 3 are fixed; The diameter of roundel is 20-22 ㎜; The diameter of big disk is 30-32 ㎜; Being radial fixing roller shaft 2 and the angle of frame 1 central shaft is 5-10 °; The axial length of roller 3 is 15-25 ㎜.

In line with the use of this utility model, shown in Figure 1, on the security window frame N NM W corresponding to each end of the two stainless steel square tube hole machining eleven poor hole, frame N to configure certain distance light stiffener L, , several Webmaster W in the utility model group under the operation, flared pipe ends produce riveting hekou G and M,, because of the two tensile strength,, test proved Webmaster W single tube tensile up to extremely heavy, , combined frame N Peng Zhang using countersunk head concealed installation method, solid to achieve the effect of anti-skid theft.
