Description

Nailing machine

Technical field

The present invention relates to the nailing machine that uses in the operation in interlocking.

Background technology

Generally, in floor construction, in most cases a plurality of flooring materials are constructed through interlocking.In the interlocking process, on backing material, place a flooring material, from squeezing into special nails such as bail obliquely to backing material, thereby flooring material is fixed on the backing material from the bight of the outstanding joint tongue base portion of flooring material end face.This joint tongue is engaged, knock-in tack obliquely in the same manner from the bight of the joint tongue base portion that forms at end face in abutting connection with the opposite side of the end face with being formed with accepting groove of flooring material with the accepting groove of the flooring material end face that is formed at adjacency.Repeat this operation.

In this floor construction process, need nail be squeezed into the bight that forms by joint tongue and flooring material end face with the angle of 45 degree.But the bight between the flooring material end face of joint tongue and its base portion is narrow.The front end of nailing machine breaks away from the bight easily when therefore, squeezing into.Nail squeeze into position deviation the time, can produce following problems: produce the cokled surface of joint tongue crackle, flooring material, or ailhead is outstanding and chimeric bad with the accepting groove of next flooring material from the surface of flooring material.

In order to eliminate this unfavorable condition, proposed to penetrate floor construction that the fore-end of nail is set as wedge shape with nailing machine (for example with reference to No. 3531313 communique of Japan Patent).Because fore-end attenuates, thereby fore-end reaches the bight of joint tongue base portion, and fore-end contact with the bight and becomes stable, and the easy aligning of will following closely from the bight of flooring material is squeezed into.

But this floor construction is used nailing machine, though squeeze into the position in guiding, squeeze into posture aspect good, the fore-end of nail exit wound of bullet and the nosed that directly contacts with flooring material have produced the gap between partly.That is, between the bight of nail exit wound of bullet and flooring material, produced the space.Owing to can not get supporting at this space nail, thereby the maintenance of the posture of nail is insufficient.Therefore, under the situation of harder flooring material nailing such as no dirty material, have following problem: nail bends in the space that can not fully keep following closely, thereby produces and buckle.

Summary of the invention

One or more embodiment according to the present invention provides a kind of nailing machine, can action be squeezed in the bight that the nail of getting from exit wound of bullet fully stably remains on the joint tongue base portion of flooring material, thereby can prevent buckling of non-magnetic shim reliably.

One or more embodiment according to the present invention provides a kind of nailing machine, and it comprises: tool body has strike mechanism; With contact head, can squeeze into the front end that reciprocatingly is located at above-mentioned tool body on the direction at nail.Front end at the contact head has the front and back, and the front and back angulation is below 90 degree.Form the exit portal of supplying with the nail of being squeezed into by strike mechanism in the inside of contact head, exit portal is to the boundary portion opening of above-mentioned front and back.

According to one or more embodiment of the present invention, the front end of contact head can be reliably contacts with the bight of the joint tongue base portion of flooring material, and almost very close to each other between the peristome of exit wound of bullet and bight.Therefore, owing to can very stably keep the nail got from exit wound of bullet, until penetrating fully, thereby can prevent buckling of non-magnetic shim reliably from exit wound of bullet.

The specific embodiment

Fig. 1 is the perspective view of nailing machine; Fig. 2 is the longitudinal sectional view of nailing machine shown in Figure 1; Fig. 3 is the enlarged drawing of the part of Fig. 2.In the drawings, label 1 expression nailing machine.Nailing machine 1 comprises: the handle 3 that has the tool body 2 that hits mechanism, rearward dispose from tool body 2, the contact head 4 that is provided with highlightedly from the front end of tool body 2 with to the rectangular nail casket 5 that is formed on the exits wound of bullet 6 supply connected nails (bail) that contacts head 4 inside.

Hitting mechanism comprises: be housed in the trigger valve 13 that hammers into device 7, the strike piston 8 that combines with the upper end one that hammers into device 7, accommodates the strike cylinder 9 that hits piston 8 sliding freely, the upper end of the air chamber 10 of the interior storing compressed air of tool body 2 and strike cylinder 9 is carried out the main valve 11 of open and close controlling and controlled the switching of main valve 11 through the operation of trigger 12 on the exit wound of bullet 6 sliding freely.Hammer into device 7 and get the bail ahead that supplies to exit wound of bullet 6 from the nail supply passageway of nail casket 5.

Contact head 4 is arranged to squeeze on the direction at nail and is moved back and forth, and the front end 4a of contact head 4 is outstanding from tool body 2.As shown in Figure 3, the other end 4b of contact head 4 can engage with the spring 16 on the contact lever that is located at trigger 12 15, and all the time by spring to direction (nail the is squeezed into direction) application of force of giving prominence to from tool body 2.During knock-in tack, be pressed in flooring material etc. and be driven into its relative tool body 2 is relatively moved to the top shown in the dotted line among Fig. 3 through contacting head 4, the end 4b through contact head 4 rotates contact lever 15.When under this state, trigger 12 being carried out pull operation, at first effectively valve rod 18 is pressed into trigger valve 13 actions.Action through trigger valve 13 makes main valve 11 carry out opening action, hits piston 8 and utilizes the compressed air in the air chamber 10 to squeeze into driving.That is,, just can not get bail through hitting mechanism as long as contact head 4 does not move to squeezing into direction in the opposite direction with nail.So, contact head 4 has the ejaculation function of getting nail and as the function of the safety device that hits mechanism.

The front 17a of the front end face 17 of contact head 4 clips exit wound of bullet 6 and forms the angle below 90 degree with back 17b.As shown in Figure 4, exit wound of bullet 6 forward end face 17 front 17a with the back 17b boundary portion be top 19 openings.Preferably, front 17a tilts about 40 degree (with reference to Fig. 3 and Fig. 5) with respect to exit wound of bullet 6.

Then, through nailing machine with flooring material with nail when being fixed on the backing material, as shown in Figure 5, the top 19 of the front end face 17 of contact head 4 is abutted on the bight 22 of base portion of joint tongue 21 of flooring material 20.Because the front 17a of front end face 17 and back 17b angulation be below 90 degree, thereby top 19 is abutted on the bight 22 reliably.And, the top 19 of the front end face 17 that contacts head 4 is pressed on the flooring material 20.Thus, though the tool body 2 of nailing machine moves downwards, contact head 4 relatively moves to the top relative to tool body 2, becomes the state that trigger 12 moves effectively.Make the strike mechanism action through pulling trigger 12, can get the bail 23 of front with the angle of about 45 degree.

The front 17a of the front end face 17 of

contact head

4 and 17b angulation at the back form identically or littler than it with the angle in the bight 22 of the base portion of the joint tongue 21 of flooring material 20, and exit wound of bullet 6 is top 19 openings of end face 17 forward.Therefore, almost very close to each other between the front end of exit wound of bullet 6 and bight 22.Therefore, because the front end of the bail of getting from exit wound of bullet 6 23 is driven into bight 22 in the moment of getting from the openend of exit wound of bullet 6, thereby the front end of bail 23 can not rock.During after bail 23 has just been got from exit wound of bullet 6 until being driven into flooring material 20 to a certain extent, the posture of bail 23 is unstable, thereby along with becoming of squeezing into is stable.But; According to present embodiment; Because almost very close to each other between the peristome of exit wound of bullet 6 and flooring material 20, thus bail 23 get from exit wound of bullet 6 back until being driven into flooring material 20 to a certain extent during, the posture of bail 23 also can continue to remain in the exit wound of bullet 6; Thereby can fully stably continue to keep, till bail 23 is got fully.Therefore, bail 23 is buckled in the time of can preventing to squeeze into reliably.

In addition, as shown in Figure 5, the outstanding equal in length of the front 17a of the front end face 17 of contact head 4 and length and the joint tongue 21 of back 17b or more than it, get final product.

And, guarantee to contact the width of the front end face 17 of head 4 to a certain extent, nailing machine is difficult for to horizontal inclination.But, when the width of front end face 17 is wide, is difficult to know from where getting bail, thereby has unworkable problem.In the present embodiment, like Fig. 6 and shown in Figure 7, form discretely about the front 17a of the front end face 17 of nailing machine, middle body 17c (recess) is lower.Bail 23 is got from the position of middle body 17c on the width of front end face 17.Therefore, middle body 17 becomes the target of squeezing into the position, thereby can know from where getting bail 23.

Though with reference to specific embodiment the present invention has been described at length, those skilled in the art certainly carry out various changes, modification under the situation that does not break away from purport of the present invention and scope.

The application with the Japanese patent application that proposed on December 21st, 2005 (Japan special be willing to 2005-368023) as the basis, in this reference and quote its content.
