Description

Technical Field

[0001] The utility model relates to the field of concrete pipe pile manufacturing, in particular to the field of cage reinforcement production, and specifically refers to a slotted rivet cutter. Background Art

[0002] Typically, during the construction of bridges, culverts, or high-rise buildings, foundation piles are driven according to construction requirements. A reinforcement cage is then lowered into the pile hole, and a guide tube is inserted into the hole for concrete pouring. The reinforcement cage primarily serves as a tensile strength barrier. Concrete has high compressive strength but low tensile strength. The reinforcement cage constrains the pile concrete, allowing the entire concrete structure to withstand a certain amount of axial tension. The reinforcement cage primarily consists of a main reinforcement cage and end plate assemblies fixed to each end of the main reinforcement cage. The end plates in the end plate assembly are typically secured with ferrules around their perimeters by riveting. Hoop riveting is a necessary step in the production of steel cages. In current conventional production, one or more rivet cutters are often used to complete the riveting through vertical or horizontal riveting. However, in the actual production process, there is a common deviation in the outer diameter processing of the end plate, combined with the abnormal length of the hoop skin when the hoop skin is cut, which often leads to a mismatch between the outer diameter of the end plate and the inner diameter formed by the hoop skin during riveting. For example, if the outer diameter of the end plate is too small, the hoop skin is prone to falling off; if the outer diameter of the end plate is too large, it will lead to edge cutting, etc., causing the riveting process to fail.

[0003] Based on this, it is necessary to propose a ferrule riveting process solution to solve the shortcomings of the current existing technology. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings of the above-mentioned prior art and provide a solution of a slotted rivet cutter.

[0005] In order to achieve the above purpose, the utility model is a slotted rivet cutter as follows:

[0006] The main feature of the slotted rivet cutter is that the slotted rivet cutter is provided with a plurality of notched edges on the blade of the rivet cutter, and is a concentric circle structure with a central hole. The plurality of notched edges are arranged on the outer periphery of the concentric circle structure. The rivet cutter blade contacts the sleeve skin through intermittent riveting action, so that the entire sleeve skin is tightly fitted with the end plate groove under the action of multiple circles of riveting pressure of the notched edges.

[0007] Preferably, the cutting edges are evenly distributed on the outer periphery.

[0008] Preferably, the cutting edges are unevenly distributed on the outer periphery.

[0009] Preferably, the cutting edge is designed as a special-shaped edge.

[0010] Preferably, the number of the missing cutting edges is set to be single or multiple.

[0011] Preferably, the circumference of the rivet cutter blade is set to be not an integer multiple of the circumference of the end plate groove to be riveted.

[0012] Preferably, the slotted rivet cutter is configured as an integrated rivet cutter or a multi-row blade rivet cutter.

[0013] The slotted rivet cutter of the present invention can effectively solve the problem of rotational riveting deviation caused by the lack of tight fit between the ferrule skin and the end plate slot. Through the design of the missing cutting edge, the abnormal deviation of the ferrule skin caused by the lack of tight fit between the ferrule skin and the end plate during the continuous rotational riveting process can be accommodated, thereby successfully riveting the ferrule skin with mismatched sizes to the end plate slot.

[0026] In order to more clearly describe the technical content of the present invention, further description will be given below in conjunction with specific embodiments.

[0027] Before describing in detail the embodiments of the present invention, it should be noted that, hereinafter, the terms "comprises", "comprising" or any other variations are intended to cover non-exclusive inclusion, whereby a process, method, article or apparatus comprising a series of elements includes not only these elements, but also other elements not expressly listed or inherent to such process, method, article or apparatus.

[0028] See also Figures 2 to 4 As shown, the slotted rivet cutter of the present invention, wherein the slotted rivet cutter is provided with a plurality of notched edges 2 on the rivet cutter blade 1, and is a concentric circle structure with a center hole, and the plurality of notched edges 2 are arranged on the outer periphery of the concentric circle structure, and the rivet cutter blade 1 contacts the sleeve skin 3 through intermittent riveting action, so that the entire sleeve skin 3 is tightly fitted with the end plate groove 4 under the riveting pressure of multiple circles of the notched edges 2.

[0029] As a preferred embodiment of the present invention, the cutting edges 2 are evenly distributed on the outer periphery.

[0030] As a preferred embodiment of the present invention, the cutting edges 2 are unevenly distributed on the outer periphery.

[0031] As a preferred embodiment of the present invention, the cutting edge 2 is designed as a special-shaped edge.

[0032] As a preferred embodiment of the present invention, the number of the cutting edges 2 is set to be single or multiple.

[0033] As a preferred embodiment of the present invention, the circumference of the rivet cutter blade 1 is set to be not an integer multiple of the circumference of the end plate groove 4 to be riveted.

[0034] As a preferred embodiment of the present invention, the slotted rivet cutter is configured as an integrated rivet cutter or a multi-row blade rivet cutter.

[0035] like Figure 1 As shown, in the prior art, the blade of the annular rivet cutter 1 is continuous, that is, during riveting, the blade contact point, the ferrule skin and the riveted end plate groove are in continuous contact; the changing length of the blade contact point, the ferrule skin riveting length and the length of the riveted end plate groove are all changing and moving at the same distance; when the ferrule skin is not tightly fitted with the end plate groove, the continuous blade riveting causes some slight deviation / extra ferrule skin deviation / extra amount to gradually accumulate and increase; eventually, the ferrule skin cannot be completely screwed into the end plate groove, causing the ferrule to fail.

[0036] In this regard, the present technical solution addresses the shortcomings of the existing technology and designs a discontinuous slotted rivet cutter; when the rivet cutter blade 1 contacts the sleeve skin 3 and presses it into the end plate groove 4, it is intermittent; at this time, the excess sleeve skin 3 can be squeezed into the missing cutting edge 2; when the rivet cutter is riveted to this position again, the excess sleeve skin 3 contacts the continuous blade and can be riveted into the end plate groove 4, that is, the slotted rivet cutter acts continuously along the rivet edge, and its missing cutting edge design can realize intermittent riveting action. After multiple rounds of riveting, the sleeve 3 skin is completely screwed into the end plate groove 4.

[0037] In actual application, the blade of the slotted rivet cutter is provided with several notched edges 2, which can effectively solve the problem that when the ferrule skin is not tightly fitted with the end plate groove 4, continuous blade riveting causes the deviation of some slightly deviated ferrule skins 3 to increase.

[0038] At the same time, since the circumference of the blade of the slotted rivet cutter of the present technical solution is not an integer multiple of the circumference of the end plate groove to be riveted, the ferrule with the missing cutting edge that was not riveted in the first circle can be riveted into the end plate groove when the second circle is riveted, so that under the action of multiple circles of riveting, the ferrule skin 3 can be completely screwed into the end plate groove 4.

[0039] The slotted rivet cutter of the present invention can effectively solve the problem of rotational riveting deviation caused by the lack of tight fit between the ferrule skin and the end plate slot. Through the design of the missing cutting edge, the abnormal deviation of the ferrule skin caused by the lack of tight fit between the ferrule skin and the end plate during the continuous rotational riveting process can be accommodated, thereby successfully riveting the ferrule skin with mismatched sizes to the end plate slot.

[0040] In this specification, the present invention has been described with reference to specific embodiments thereof. However, it will be apparent that various modifications and variations may be made without departing from the spirit and scope of the present invention. Accordingly, the specification and drawings are to be regarded as illustrative rather than restrictive.
