Description

Technical Field

[0001] The present invention relates to a protective member for a portable cutting machine attached to a portable cutting machine for cutting rod-shaped members such as reinforcing bars and round bars for concrete reinforcement.

Background Art

[0002] At construction sites such as building sites and civil engineering sites, portable cutting machines are used to cut rod-shaped members (workpieces) such as reinforcing bars and round bars for concrete reinforcement. The main body of the portable cutting machine is composed of a combination of a housing, a cylinder, a pump case, and a motor housing. The portable cutting machine is, for example, of a handgun type with a gripping portion formed on the motor housing, and the user of the portable cutting machine can grip (carry) the portable cutting machine with one hand by the gripping portion.

[0003] A cutting portion for cutting the rod-shaped member is provided at the tip of the piston in the housing and the cylinder. The cutting portion is a pair of cutters consisting of a movable cutter and a fixed cutter. A piston is disposed in the cylinder so as to be reciprocally movable, and a movable cutter is provided at the tip of the piston of the cylinder. By the piston reciprocating inside the cylinder, the movable cutter provided at the tip of the piston can be drawn out (advanced) or drawn in (retreated). The fixed cutter is provided at a position facing the movable cutter in the housing.

[0004] The portable cutting machine is, for example, a hydraulic type and has a reservoir (oil tank) in the main body. Further, as the power source of the portable cutting machine, for example, an AC power source, a built-in battery, etc. are used. When cutting a rod-shaped member, the user first places the rod-shaped member between the cutting parts (a pair of cutters). Specifically, at the desired cutting position, the user places the rod-shaped member such that the direction perpendicular to the longitudinal direction of the rod-shaped member coincides with the moving direction of the movable cutter (the direction in which the cylinder reciprocates). When the user turns on the power of the portable cutting machine, the piston is pulled out (moves forward). The rod-shaped member is cut at the desired cutting position by the movable cutter at the tip of the piston of the cylinder and the fixed cutter located opposite thereto, on a plane perpendicular to its longitudinal direction.

[0005] When cutting a hard rod-shaped member, there is a risk that the cut rod-shaped member or its fragments may scatter and injure the user. Therefore, a protective member for preventing scattering is attached to the portable cutting machine (for example, Japanese Unexamined Patent Application Publication No. 2019-058971).

[0006] In Japanese Unexamined Patent Application Publication No. 2019-058971, a box-shaped protective member that covers the cutting part is attached to the portable cutting machine. A pair of insertion holes facing each other are formed in the box-shaped protective member. When cutting a rod-shaped member, the user first inserts the rod-shaped member into the pair of insertion holes in its longitudinal direction. In other words, the rod-shaped member is inserted into the pair of insertion holes and penetrates the box-shaped protective member. Then, when the user turns on the power of the portable cutting machine, the movable cutter inside the box-shaped member is pulled out (moves forward), and the cutting part cuts the rod-shaped member in a direction perpendicular to its longitudinal direction.

Summary of the Invention

Problems to be Solved by the Invention

[0008] In Japanese Patent Application Laid-Open No. 2019-058971, the cutting portion is covered with a box-shaped protective member, and the box-shaped protective member prevents the scattered rod-shaped member or its fragments cut by it.

[0009] However, since the entire cutting portion is covered by the box-shaped protective member, the cutting position of the rod-shaped member cannot be visually recognized when the rod-shaped member is cut. Therefore, there is a possibility that the rod-shaped member may be cut at the wrong position or the cutting surface may be oblique (not the surface perpendicular to the longitudinal direction). In addition, since there is no member for holding the rod-shaped member inside the box-shaped protective member during cutting, the rod-shaped member may be pushed against the movable cutter or piston during cutting, and the cutting position may move significantly. In this regard as well, the possibility of cutting the rod-shaped member at the wrong position cannot be denied. Furthermore, it is necessary to pre-form the box-shaped protective member in a shape and size that cover the entire cutting portion, and the configuration is complicated. In particular, it is difficult to change the shape and size of the pair of insertion holes according to the shape and thickness of the cross-section of the rod-shaped member, and the box-shaped protective member has low versatility.

[0010] An object of the present invention is to provide a protective member for a portable cutting machine that can surely cut a rod-shaped member at a desired position, prevent the scattered cut rod-shaped member or its fragments, and is versatile and has a simple configuration for rod-shaped members with different cross-sectional shapes and sizes.

Means for Solving the Problems

[0011] In order to achieve the above object, in the present invention, the protective member is provided close to the cutting portion. The protective member has a holding portion and a covering portion. The holding portion holds the rod-shaped member, and the covering portion covers at least a part of the cutting portion. That is, according to the present invention according to claim 1, in a protective member of a portable cutting machine including a cutting portion for cutting the rod-shaped member in a plane perpendicular to the longitudinal direction of the rod-shaped member, the protective member is provided close to the cutting portion, has a holding portion and a covering portion, the holding portion can hold the rod-shaped member in its longitudinal direction, the covering portion covers at least a part of the cutting portion, and the cutting portion can be visually recognized from a portion not covered by the covering portion.

Advantages of the Invention

[0012] In the present invention according to claim 1, the holding portion holds the rod-shaped member in its longitudinal direction, so that the relative position of the rod-shaped member with respect to the cutting portion is fixed. Therefore, when cutting, the rod-shaped member is prevented from being pushed by the cutting portion (movable cutter) and moving greatly, and the rod-shaped member can be cut at a desired position. Further, the covering portion is formed in a shape that covers at least a part of the cutting portion, preventing the scattered pieces of the cut rod-shaped member. The cutting position can be confirmed by visually observing the cutting portion (or the holding portion, the rod-shaped member) from the non-covered portion of the covering portion, and the rod-shaped member can be cut at a desired position. Furthermore, since the holding portion holds the rod-shaped member, it is not necessary to change the shape of the protective member according to the cross-sectional shape and size of the rod-shaped member, and the versatility of the protective member is high. And it is sufficient for the protective member to have a holding portion and a covering portion, and its structure is simple.

[0014] In a protective member of a portable cutting machine including a cutting portion that cuts the rod-shaped member on a plane orthogonal to the longitudinal direction of the rod-shaped member, the protective member is provided close to the cutting portion and has a holding portion and a covering portion. The holding portion enables the rod-shaped member to be held in its longitudinal direction, and the covering portion covers at least a part of the cutting portion and enables the cutting portion to be visible from a location not covered by the covering portion.

Embodiment

[0015] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view of a protective member of a portable cutting machine according to an embodiment of the present invention and a portable cutting machine with the protective member attached, where (A) shows a perspective view from the left rear and (B) shows a perspective view from the right rear. FIG. 2(A) is a plan view of the protective member of the portable cutting machine and the portable cutting machine with the protective member attached, and (B) is a partial plan view of the portable cutting machine excluding the upper surface (top surface) from (A). FIG. 3 is a perspective view of the protective member of the portable cutting machine, where (A) shows a perspective view from the left rear and (B) shows a perspective view from the right rear. Note that, unless otherwise specified, front, rear, up, down, left, and right refer to the directions as seen from the user of the portable cutting machine, and are denoted by Fr, Rr, Up, Lw, L, and R.

[0016] As shown in FIGS. 1(A) and (B), the basic configuration of the portable cutting machine 1 is the same as that of the prior art. The main body 10 of the portable cutting machine is composed of a combination of a housing 12, a cylinder 14, a pump case 16, and a motor housing (not shown). The portable cutting machine 1 is, for example, of a handgun type with a gripping portion (not shown) formed on the motor housing, and the user can hold the gripping portion (not shown) and use and carry the portable cutting machine with one hand.

[0017] The housing 12, the cylinder 14, the pump case 16, and the motor housing (not shown) are each formed, for example, from a cast iron alloy or the like. A pump (not shown) is housed in the pump case, a motor (not shown) is housed in the motor housing, and a piston 14-1 (see FIG. 2(A)) is disposed in the cylinder so as to be reciprocable. On the side surface of the cylinder 14 (the left side surface in Fig. 1(A)), there is provided a side handle mounting hole 14-2 for mounting a separate side handle (not shown), but this is not essential. If a separate side handle is mounted in the side handle mounting hole 14-2, the user can hold the gripping portion (not shown) with one hand and the side handle with the other hand respectively, and prevent the portable cutting machine 1 from shaking when cutting the rod-shaped member 30.

[0018] The motor housing (not shown) is connected to the pump case 16 (the rear part of the pump case in Fig. 1(A)(B)), but it may be connected to the pump case in advance and integrated with the main body, or may be a separate body. A power source is connected to the motor inside the motor housing (not shown), and an AC power source, a built-in battery, etc. are used as the power source. The motor housing (not shown) is provided with a power switch (not shown) for driving the motor. Note that the motor housing (not shown) may be rotatable with respect to the pump case 16, but this is not essential.

[0019] The portable cutting machine 1 is, for example, a hydraulic type, and a reservoir (oil tank, not shown) is provided inside the pump case 16. An oil plug 16-1 for injecting oil into the reservoir is provided on the side surface of the pump case 16 (the left side surface in Fig. 1(A)). Generally, first and second chambers (not shown) communicating with the main body 10 are defined before and after sandwiching a piston head (not shown). When the power switch of the motor housing (not shown) is turned on, the motor and the pump are started, the oil in the reservoir inside the main body is pressurized and supplied to the first chamber, and the piston 14-1 in the cylinder moves forward.

[0020] At the tip of the housing 12 and the piston 14-1 in the cylinder, cutting portions 12a and 14a are respectively provided. The cutting portions 12a and 14a are a pair of cutters, which are respectively a fixed cutter and a movable cutter. The movable cutter 14a is provided at the tip of the piston 14-1 in the cylinder, and the fixed cutter 12a is provided at a position in the housing 12 facing the movable cutter.

[0021] As shown by the dashed-dotted line in Fig. 2(A), a rod-shaped member (workpiece) 30 such as a reinforcing bar or round bar for concrete reinforcement is installed so that its longitudinal direction is sandwiched by the cutting portions, that is, the movable cutter 14a and the fixed cutter 12a. In other words, the rod-shaped member (workpiece) 30 is installed so that its longitudinal direction is orthogonal to the moving direction of the piston 14-1 (i.e., the reciprocating direction of the movable cutter 14a; the direction of the arrow in Fig. 2(A)).

[0022] As shown in Figs. 1(A)(B) and Fig. 2(A), the protection member 20 is provided close to the cutting portions 12a and 14a and has a holding portion 22 and a covering portion 24. As shown in Figs. 1(A)(B), etc., the holding portion 22 has a pressing portion 22-1 and a receiving portion 22-2. The pressing portion 22-1 is connected to the movable cutter 14a, and the receiving portion 22-2 and the covering portion 24 are arranged close to the fixed cutter 12a.

[0023] As can be clearly seen by referring to Figs. 3(A)(B) in combination with Figs. 1(A)(B), the pressing portion 22-1 is formed, for example, by bending the tip of a plate-shaped member. At least one or more mounting holes 22-1a1 are formed in the bent tip surface 22-1a of the pressing portion 22-1. Also, as shown in Fig. 2(B), another mounting hole 14a-1 corresponding to the mounting hole 22-1a1 is formed in the movable cutter 14a. The mounting hole 14a-1 is a threaded hole with threads cut. By engaging a bolt 22-1a2 (see Fig. 2(A)) with the mounting hole 22-1a1 of the pressing portion and the other mounting hole 14a-1 of the movable cutter 14a, the pressing portion is fixed to the movable cutter. Note that the attachment of the pressing portion 22-1 is not limited to the engagement of the bolt 22-1a2, and it is sufficient that the pressing portion is attached to the movable cutter 14a provided at the tip of the piston in the cylinder 14. Further, the position and number of the attachment holes 22-1a1 are not limited to those described.

[0024] The receiving portion 22-2 is provided facing the pressing portion 22-1 and is arranged close to the fixed cutter 12a. The receiving portion 22-2 has, for example, a substantially rectangular shape and is formed of an elastic member such as rubber. A groove 22-2a having a shape corresponding to the cross-sectional shape of the rod-shaped member 30 is provided in the surface of the receiving portion 22-2 facing the pressing portion 22-1 (the rear surface in FIGS. 1(A) and 1(B)). The groove 22-2a is formed in a substantially semi-circular cross-sectional shape. Note that the formation of the groove 22-2a is not essential and is not limited to this shape.

[0025] As will be described later, the receiving portion 22-2 is attached to the covering portion 24 via the attachment member 26, and the covering portion is attached to the housing 12. In other words, the receiving portion 22-2 is attached to the housing 12 together with (via) the covering portion 24.

[0026] The covering portion 24 is formed by combining, for example, a plurality of plate-like members. As shown in FIGS. 3(A) and 3(B), the covering portion 24 is configured by combining, for example, an upper surface (top surface) 24a, a bent surface (front surface) 24b, and an auxiliary surface 24c. The upper surface (top surface) 24a and the bent surface (front surface) 24b are formed by bending a single plate-like member by 90 degrees. Then, another plate-like member is attached so as to be orthogonal to the upper surface and the bent surface at a position surrounded by the upper surface 24a and the bent surface 24b, thereby forming the auxiliary surface 24c. Note that the formation method of the covering portion 24 is not limited to this.

[0027] According to FIGS. 3(A) and 3(B), at the position surrounded by the upper surface 24a and the bent surface 24b, the auxiliary surface 24c is arranged on the left side of the center, and the receiving part 22-2 is arranged on the right side of the center, respectively. Also, as can be seen by referring to FIG. 1(B) in conjunction with FIGS. 3(A) and 3(B), the fixed cutter 12a is located between the auxiliary surface 24c and the receiving part 22-2.

[0028] At least one mounting hole 24c-1 is formed in the auxiliary surface 24c. As shown in FIG. 2(B), another mounting hole 12a-1 corresponding to the mounting hole 24c-1 is formed in the fixed cutter 12a. A part of the housing 12 is located between the auxiliary surface 24c and the fixed cutter 12a, and another mounting hole 12h is formed in this housing. Each of the mounting holes 24c-1 and 12h is a threaded hole with threads cut. By engaging a bolt 40 with the mounting hole 24c-1 of the auxiliary surface, the mounting hole 12a-1 of the fixed cutter, and the mounting hole 12h of the housing, the covering part 24 is fixed to the fixed cutter 12a. Note that the attachment of the covering part 24 is not limited to the engagement of the bolt 40. The position and number of the mounting holes 24c-1 are not limited to those described.

[0029] The receiving part 22-2 is attached to the covering part 24 via an attachment member 26. As can be seen by referring to FIG. 3(B), the attachment member 26 is formed, for example, by bending a thin plate-like member into a U-shaped cross-section, and a substantially rectangular receiving part 22-2 can be arranged inside the bent part. A pair of mounting holes 26-1 are formed in the attachment member 26. Also, at a predetermined position on the covering part 24, for example, on the bent surface 24b, another mounting hole 24b-1 corresponding to the pair of mounting holes 26-1 is formed. An engaging member 28 composed of a bolt 28-1 that can be inserted into the mounting hole 26-1 of the attachment member and another mounting hole 24b-1 of the covering part, and a nut (not shown) corresponding to the bolt is provided as another member. Further, a spring member (coil spring) 28-2 wound around the outer peripheral surface of the shaft of the bolt 28-1 is provided as another member. As shown in Fig. 1(B), first, the receiving part 22-2 is enclosed in the mounting member 26. The bolt 28-1 of the engaging member is inserted through the mounting hole 26-1 of the mounting member, the spring member 28-2 is wound around the outer peripheral surface of the bolt, and then it is inserted through another mounting hole 24b-1 of the covering part, and a nut (not shown) of the engaging member is engaged, so that the receiving part 22-2 is fixed to the covering part 24 via the mounting member 26. Note that the attachment of the receiving part 22-2 and the mounting member 26 is not limited to the engagement of the engaging member 28, and it is only necessary that the receiving part 22-2 is attached in the vicinity of the fixed cutter 12a. Also, the position and number of the mounting holes 26-1 are not limited to those described.

[0030] As shown in Figs. 1(A) and (B), the covering part 24 covers at least a part of the cutting part (fixed cutter 12a). The part not covered by the covering part 24 is open, and for example, the cutting part (fixed cutter 12a, movable cutter 14a) is visible from the upper part of the covering part. The reference numeral 24-1 indicates the opening.

[0031] The attachment of the protection member 20 to the portable cutting machine 1 before cutting the rod-shaped member 30 will be described. First, the bolt 22-1a2 is inserted through and engaged with the mounting hole 22-1a1 of the pressing part and another mounting hole 14a-1 of the movable cutter 14a, and the pressing part 22-1 is attached to the movable cutter 14a. Thereby, the pressing part 22-1 is attached to the cylinder 14 via the movable cutter 14a.

[0032] Next, among the surfaces of the receiving part 22-2, the surface (front surface) facing the groove 22-2a and the upper and lower surfaces are adhered to the bent inner surface of the mounting member 26 to integrate the receiving part and the mounting member. A pair of engaging members 28 (bolt 28-1, nut (not shown)) with the spring member 28-2 wound around are respectively inserted through and engaged with a pair of mounting holes 26-1 of the mounting member, and the receiving part 22-2 is attached to the covering part 24 via the mounting member 26. Insert the bolt 40 through the mounting hole 24c-1 of the auxiliary surface, the mounting hole 12h of the housing, and the mounting hole 12a-1 of the fixed cutter, and engage them to attach the covering portion 24 to the fixed cutter 12a. Thereby, the receiving portion 22-2 and the covering portion 24 are attached to the housing 12.

[0033] Describe the cutting of the rod-shaped member 30. The user of the portable cutting machine 1 places the rod-shaped member 30 so as to sandwich it in the longitudinal direction between the pressing portion 22-1 and the receiving portion 22-2 (Fig. 2(A)). More specifically, since the pressing portion 22-1 moves together with the piston 14-1, the rod-shaped member 30 is disposed in contact with the receiving portion 22-2 (groove 22-2a), and a space for the movement of the pressing portion is created between the rod-shaped member and the pressing portion. The user visually checks from the opening 24-1 (from above) whether the positions of the cutting portions 12a and 14a located between the pressing portion 22-1 and the receiving portion 22-2 match the desired cutting position of the rod-shaped member 30, and positions the rod-shaped member and the portable cutting machine (cutting portion). Tighten each bolt and nut to fix the pressing portion 22-1 and the receiving portion 22-2 respectively.

[0034] Next, the user turns on the power switch of the portable cutting machine 1 provided on the motor housing (not shown). When the power is turned on, the motor and the pump are started, and the movable cutter 14a at the tip of the piston 14-1 advances. As the movable cutter 14a advances, the pressing portion 22-1 attached to the movable cutter 14a approaches the rod-shaped member 30 disposed in the receiving portion 22-2. The rod-shaped member 30 is cut by the advancing movable cutter 14a and the fixed cutter 12a located opposite to the movable cutter in a plane perpendicular to the longitudinal direction at the desired cutting position of the user.

[0035] When the rod-shaped member 30 is cut, the holding portion 22 (pressing portion 22-1, receiving portion 22-2) clamps and holds the rod-shaped member, so that the relative position of the rod-shaped member with respect to the cutting portions 12a and 14a is fixed. Therefore, when cutting, the rod-shaped member 30 is prevented from being pushed by the cutting portion, particularly the movable cutter 14a that advances, and the piston 14-1, and the rod-shaped member can be cut at a desired position.

[0036] Before the rod-shaped member 30 is cut, the upper surface 24a of the covering portion covers the upper part of the fixed cutter 12a attached to the housing 12. Also, the bent surface 24b and the auxiliary surface 24c cover the front part and the left part of the fixed cutter 12a, respectively. And when the rod-shaped member 30 is cut, since the movable cutter 14a advances, not only the upper part of the fixed cutter 12a but also the upper part and the left part of the movable cutter are covered by the upper surface 24a and the auxiliary surface 24c of the covering portion. By covering at least a part of the cutting portions 12a and 14a with the covering portion 24 in this way, it is possible to prevent the scattered rod-shaped member 30 and its fragments from scattering.

[0037] Also, in the embodiment, the upper surface 24a of the covering portion covers not only the cutting portions 12a and 14a but also the upper part of the receiving portion 22-2. By covering at least a part of the receiving portion 22-2, for example, the upper part of the receiving portion, with the covering portion 24 in this way, it is possible to further prevent the scattered rod-shaped member 30 and its fragments from scattering. Furthermore, the pressing portion 22-1 not only presses the side surface of the rod-shaped member 30 to fix the rod-shaped member, but also can prevent the rod-shaped member 30 and its fragments cut by the tip surface 22-1a close to the fixed cutter 12a from scattering to the right.

[0038] The covering portion 24 covers the fixed cutter 12a and enables the fixed cutter to be visible from the uncovered portion (opening 24-1) of the covering portion. Therefore, the user of the portable cutting machine 1 can confirm the desired cutting position of the rod-shaped member 30 from the opening 24-1 and cut the rod-shaped member at the desired position.

[0039] If the receiving part 22-2 is formed of an elastic member such as rubber, it is not necessary to change the shape of the protection member 20 according to the cross-sectional shape and size of the rod-shaped member 30, and the versatility of the protection member is further enhanced. Further, if the receiving part 22-2 is formed of an elastic member, it is possible to prevent the displacement, wobbling of the rod-shaped member, and the transmission of vibration from a motor (not shown) during cutting. Furthermore, if a groove 22-2a corresponding to the cross-sectional shape of the rod-shaped member 30 is formed in the receiving part 22-2, it goes without saying that the displacement and wobbling of the rod-shaped member during cutting can be further prevented because the rod-shaped member 30 is held on the inner surface of the groove.

[0040] The user can fix the protection member 20 (holding part 22, covering part 24) while checking the positions of the protection member 20 and the rod-shaped member 30 by an engagement member (bolt, nut) 28 or the like. Further, the spring member 28-2 can prevent the transmission of vibration from a motor (not shown) during cutting, and further reduce the load applied from the movable cutter 14a to the rod-shaped member 30 during cutting.

[0041] The above-described embodiments are for explaining the present invention, and do not limit the present invention. Needless to say, all modifications and improvements within the technical scope of the present invention are included in the present invention. For example, the shapes of the holding part (pressing part, receiving part) and the covering part are not limited to the shapes of the embodiments. The pressing part is provided on the piston (movable cutter), and the receiving part and the covering part are provided on the housing, respectively, but are not limited thereto. The position of the opening is also not limited to the position of the embodiment.
