Description

Technical Field

[0001] The present invention relates to the technical field of wooden hanger production, and particularly relates to a wooden hanger profiling machine and a cutting method. Background Art

[0002] During the production of wooden hangers, it is necessary to round the edges of the hangers to make the edge surfaces of the hangers smoother. During the production process, the wooden hangers need to be positioned and clamped, and then a profiling tool is used to perform profiling cutting on the edges of the hangers to achieve efficient processing.

[0003] To ensure the processing quality of the edges of wooden hangers, the positioning of wooden hangers is quite important. However, the cutting equipment in the prior art fails to accurately position the wooden hangers, resulting in unqualified processing quality of the edges of wooden hangers. In addition, sometimes the processed wooden hangers cannot be discharged successfully, resulting in material blockage. Summary of the Invention

[0008] Specifically, the clamping tooling is provided with two positioning cavities arranged vertically, the clamping tooling is provided with a positioning back strip and a supporting bottom strip, the rear end of the positioning back strip in the advancing direction is connected with a positioning block, the positioning block is provided with a long strip hole, the long strip hole is connected with the positioning back strip by screws, the positioning block is L-shaped, the positioning block is provided with an inclined positioning surface, and the inclined positioning surface is used for positioning the thick-end tenon of the hanger half-wood board. The piston rod of the clamping cylinder is coaxially fixedly connected with a sliding rod, the sliding rod is fixedly connected with two connecting blocks, and the pressing plate is fixedly connected with the connecting blocks.

[0009] Specifically, the cross-section of the storage cylinder is strip-shaped, the length direction of the cross-section of the storage cylinder is along the tangential direction of the turntable. During the rotation of the turntable, the side where other components approach the positioning cavity is defined as the cavity-approaching side, and the side where the object moves away from the positioning cavity is defined as the cavity-sending side: A passive dial rod is hinged to the bottom plate at the cavity-sending side of the storage cylinder. The passive dial rod is provided with a transverse section and a longitudinal section, so it is L-shaped. The bottom plate at the cavity-sending side of the storage cylinder is provided with an adjusting long strip hole, and an installation screw rod is installed in the adjusting long strip hole. The passive dial rod is rotatably sleeved on the installation screw rod. A limiting block is fixedly connected to the edge of the bottom plate at the cavity-sending side of the storage cylinder.

[0010] Specifically, the top side edge of the hanger half-wood board is provided with two discontinuous arc surface segments, which are respectively called the top arc surface segment and the shoulder arc surface segment.

[0011] Specifically, the base is provided with two layers of discharge receiving plates. The discharge receiving plates are approximately tangent to the turntable. The base is hinged with a swing rod. The end of the swing rod is fixedly connected with a vertical rod. The vertical rod is fixedly connected with two clamping sleeves. An insertion and extraction block is arranged on the facing cavity side of the clamping sleeve. The cross-section of the insertion and extraction block is a right triangle, thus forming an extraction inclined surface.

A plurality of cam strips are fixedly connected to the circumferential surface of the turntable. The plurality of cam strips together enclose a circle. The contact roller contacts the cam strips.

[0012] The cutting method of the wooden hanger profiling machine includes the following steps:

[0013] Pushing step: The pushing rod of the pushing mechanism pushes the two lowest-positioned hanger semi-boards in the storage cylinder into the positioning cavity of the clamping tooling.

[0014] Positioning step: The two hanger semi-boards rotate with the clamping tooling. During the rotation, the tip arc surface of the hanger semi-board will slide over the aligning arc surface of the passive lever, causing the passive lever to swing, thereby stretching the elastic rubber pull ring. The passive lever maintains elastic abutment against the tip arc surface of the hanger semi-board under the action of the elastic restoring force of the elastic rubber pull ring, so that the thick-end tenon of the hanger semi-board remains in abutment against the inclined positioning surface to achieve the positioning of the hanger semi-board.

[0015] Clamping step: The clamping cylinder drives the pressing plate to move downward, so as to jointly clamp the two hanger semi-boards with the supporting bottom strip.

[0016] Profiling cutting step: The clamping tooling drives the hanger semi-board to rotate to the profiling cutting mechanism, and the profiling cutting cutter disc cuts the top arc surface section and the shoulder arc surface section of the hanger semi-board.

[0017] Discharging step: When the clamping tooling drives the hanger semi-board to rotate to the vertical rod, the clamping cylinder drives the pressing plate to move upward to release the hanger semi-board. At this time, the contact roller just contacts the trough profile at the edge of the cam strip, so that the extraction inclined surface of the insertion and extraction block abuts against the inner side of the tip of the hanger semi-board. Subsequently, the contact roller climbs along the climbing profile at the edge of the cam strip, causing the swing rod to swing outwards, thereby driving the extraction inclined surface to push out the hanger semi-board to achieve discharging.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] First, after the hanger semi-boards are pushed into the positioning cavity, the two hanger semi-boards rotate with the clamping tooling. During the rotation, the tip arc surface of the hanger semi-board will slide over the aligning arc surface of the passive lever, causing the passive lever to swing, thereby stretching the elastic rubber pull ring. The passive lever maintains elastic abutment against the tip arc surface of the hanger semi-board under the action of the elastic restoring force of the elastic rubber pull ring, so that the thick-end tenon of the hanger semi-board remains in abutment against the inclined positioning surface to achieve the precise positioning of the hanger semi-board.

[0020] Second, the two profiling cutting mechanisms can sequentially perform profiling cutting on the top arc surface section and the shoulder arc surface section of the wooden clothes hanger semi-board, with high cutting efficiency and high cutting precision;

[0021] Third, when the clamping tooling drives the wooden clothes hanger semi-board to rotate to the vertical rod, the clamping cylinder drives the pressing plate to move upward to release the wooden clothes hanger semi-board. At this time, the contact roller just contacts the trough contour on the edge of the cam bar, so that the extraction inclined surface of the insertion and extraction block moves to abut against the inner side (the side close to the positioning back bar) of the tip of the wooden clothes hanger semi-board. Subsequently, the contact roller climbs along the climbing contour on the edge of the cam bar, causing the swing rod to swing outwards, thereby driving the extraction inclined surface to extract the wooden clothes hanger semi-board, ensuring the success rate of discharging and avoiding material blockage.

[0047] Specifically, the cross-section of the storage bin 31 is long strip-shaped, and the length direction of the cross-section of the storage bin 31 is along the tangential direction of the turntable 11. During the rotation of the turntable 11, the side where other components approach the positioning cavity 21 is defined as the cavity-approaching side, and the side where the object moves away from the positioning cavity 21 is defined as the cavity-sending side: A passive shifting rod 61 is hinged to the bottom plate at the cavity-sending side of the storage bin 31 (see Figure 6 , Figure 7 ). The passive shifting rod 61 is provided with a transverse section 612 and a longitudinal section 611, thus presenting an L shape.

[0051] The cutting method of the wooden clothes hanger profiling machine includes the following steps:

[0052] Pushing step: The pushing rod 341 of the pushing mechanism pushes the two lowest-positioned hanger semi-boards 5 in the storage cylinder 31 into the positioning cavity 21 of the clamping tooling 2;

[0053] Positioning step: The two hanger semi-boards 5 rotate with the clamping tooling 2. During the rotation, the tip arc surface 54 of the hanger semi-board 5 will slide over the aligning arc surface 6111 of the passive lever 61, causing the passive lever 61 to swing, thereby stretching the elastic rubber pull ring 64 (refer to Figure 7 ). The passive lever 61 maintains an elastic abutment against the tip arc surface 54 of the hanger semi-board 5 under the action of the elastic restoring force of the elastic rubber pull ring 64, so that the thick-end tenon 51 of the hanger semi-board 5 remains abutted against the inclined positioning surface 2131 (see Figure 4 , Figure 5 ) to achieve the positioning of the hanger semi-board 5;

[0054] Clamping step: The clamping cylinder 22 drives the pressing plate 221 to move downward, so as to jointly clamp the two hanger semi-boards 5 with the supporting bottom strip 212;

[0055] Copying cutting step: The clamping tooling 2 drives the hanger semi-board 5 to rotate to the copying cutting mechanism 4, and the copying cutting cutter head 41 cuts the top arc surface section 52 and the shoulder arc surface section 53 of the hanger semi-board 5;

[0056] Discharging step: When the clamping tooling 2 drives the hanger semi-board 5 to rotate to the vertical rod 72 (see Figure 9 ), the clamping cylinder 22 drives the pressing plate 221 to move upward to release the hanger semi-board 5. At this time, the contact roller 721 just contacts the trough contour at the edge of the cam strip 112 (as shown in Figure 9 ), so that the ejection inclined surface 7311 of the insertion and ejection block 731 abuts against the inner side of the tip of the hanger semi-board. Subsequently, the contact roller 721 climbs along the climbing contour at the edge of the cam strip 112, causing the swing rod 71 to swing outward, thereby driving the ejection inclined surface 7311 to eject the hanger semi-board 5 to achieve discharging.

[0057] The beneficial effects of the present invention are as follows:

[0058] First, after the hanger semi-board 5 is pushed into the positioning cavity 21, the two hanger semi-boards 5 rotate with the clamping tooling 2. During the rotation, the tip arc surface 54 of the hanger semi-board 5 will slide over the aligning arc surface 6111 of the passive lever 61, causing the passive lever 61 to swing, thereby stretching the elastic rubber pull ring 64 (refer to Figure 7 ). The passive lever 61 maintains an elastic abutment against the tip arc surface 54 of the hanger semi-board 5 under the action of the elastic restoring force of the elastic rubber pull ring 64, so that the thick-end tenon 51 of the hanger semi-board 5 remains abutted against the inclined positioning surface 2131 (see Figure 4 , Figure 5 ) to achieve the precise positioning of the hanger semi-board 5;

[0059] Second, the two profiling cutting mechanisms 4 can sequentially perform profiling cutting on the top arc surface section 52 and the shoulder arc surface section 53 of the hanger semi-wood board 5, with high cutting efficiency and high cutting accuracy;

[0060] Third, when the clamping tooling 2 drives the hanger semi-wood board 5 to rotate to the vertical rod 72 (see Figure 9 ), the clamping cylinder 22 drives the pressing plate 221 to move upward to release the hanger semi-wood board 5. At this time, the contact roller 721 just contacts the trough profile on the edge of the cam bar 112 (as Figure 9 shown), so that the extraction inclined surface 7311 of the insertion and extraction block 731 moves to abut against the inner side of the tip of the hanger semi-wood board (the side close to the positioning back strip 211). Subsequently, the contact roller 721 climbs along the climbing profile on the edge of the cam bar 112, causing the swing rod 71 to swing outward, thereby driving the extraction inclined surface 7311 to extract the hanger semi-wood board 5, ensuring the success rate of discharging and avoiding material blockage.

The wooden hanger profiling machine according to claim 4 is characterized in that: The top side edge of the hanger half-wood board is provided with two discontinuous arc segments, which are respectively called the top arc segment and the shoulder arc segment. The profiling cutting disc provided by one profiling cutting mechanism is used to process the top arc segment, and the profiling cutting disc provided by the other profiling cutting mechanism is used to process the shoulder arc segment.

6. The wooden hanger profiling machine according to claim 5, characterized in that: The base is provided with two layers of discharge receiving plates, which are roughly tangent to the turntable. The base is hinged with a rocker arm, a vertical rod is fixedly connected to the end of the rocker arm, two jackets are fixedly connected to the vertical rod, and an insert block is provided on the cavity side of the jacket. The cross-section of the insert block is a right-angled triangle, thereby forming an ejection slope, which gradually deviates away from the center of the circle along the rotation direction of the turntable. A contact roller is provided on the vertical rod sleeve, and a plurality of cam strips are fixedly connected to the circumference of the turntable. The plurality of cam strips together form a circle, and the contact roller is in contact with the cam strip.

7. The cutting method of the wooden hanger profiling machine as claimed in claim 6, characterized in that: The following steps are involved: Pushing step: The pushing rod of the pushing mechanism pushes the two lowest hanger half-wood boards in the storage barrel into the positioning cavity of the clamping tooling; Positioning steps: the two half-wood boards of the hanger rotate with the clamping fixture. During the rotation process, the arc surface of the tip of the half-wood board of the hanger slides over the arc surface of the passive lever, causing the passive lever to swing, thereby stretching the elastic rubber pull ring. The passive lever maintains elastic abutment against the arc surface of the tip of the half-wood board of the hanger under the elastic restoring force of the elastic rubber pull ring, thereby maintaining the thick end tenon of the half-wood board of the hanger against the inclined positioning surface, so as to achieve the positioning of the half-wood board of the hanger; Clamping steps: The clamping cylinder drives the clamping plate to move downward, thereby clamping the two half-wooden boards of the hanger together with the supporting bottom bar; Profiling cutting steps: the clamping tool drives the hanger half-wood board to rotate to the profiling cutting mechanism, and the profiling cutting cutter disc cuts the top arc surface segment and the shoulder arc surface segment of the hanger half-wood board; Discharging steps: when the clamping tool drives the hanger half wooden board to rotate to the vertical rod, the clamping cylinder drives the pressing plate to move up to release the hanger half wooden board. At this time, the contact roller just contacts the trough profile of the edge of the cam strip, so that the pulling-out slope of the plug-in block rests against the inner side of the tip of the hanger half wooden board. Then, the contact roller climbs along the climbing profile of the edge of the cam strip, causing the rocker arm to swing outward, thereby driving the pulling-out slope to pull out the hanger half wooden board to achieve discharging.
