Detailed ways

As shown in Figures 1-2, a billeting machine includes a frame 10, and the frame 10 is provided with a pushing part 20 for pushing a blank and an execution part 30 for processing a blank a, and the pushing part 20 The pushing direction is consistent with the processing direction of the blank a of the execution part 30 and the push end of the push part 20 is set at the feed end of the execution part 30. The minimum distance between the push end of the push part 20 and the feed end of the execution part 30 is greater than that of the blank a length, the pushing part 20 has two position states: one of them is to push the blank a into the execution part 30 to realize the processing of the blank a, and the other position state is that the push part 20 returns to the initial position so that the execution part 30 feeds End-feeding; wherein, the division of blank A and blank a is as shown in Figure 2-3 and Figure 6, with the bamboo and wood raw material as blank A, and the strip-shaped rough material stripped from the bamboo and wood raw material as blank a,

In order to ensure that the travel path of the blank a is accurate and ensure the quality of its finished product, as a further preferred solution of the present invention: the blanking machine also includes a guide unit 40 for guiding the blank a, and the guide unit 40 includes a guide groove 41 and a press Tight part 42, the guide path of the guide groove 41 is set to coincide with the action path of the pushing part 20, and its guide path extends inwardly from the feed end of the execution part 30 along its processing direction and ends at the discharge end of the execution part 30. The pressing part 42 is arranged on the guide groove 41 and together with the working surface of the frame 10 and the guide groove 41 constitutes a passage for the billet a to travel, as shown in FIGS. 1-3 . In practical application, as shown in Figure 1, the specific structure of the guide groove 41 can be realized by arranging pressing plates on both sides of the travel path of the blank a, the guide groove 41 is formed by relying on the gap between the pressing plates, and the pressing part 42 is directly fixed to the pressing plate so that it, together with the working surface of the frame 10 and the guide groove 41, constitutes a passage for the blank a to travel, and its pressing part 42 can be arranged in multiple groups according to the actual situation, so as to finally achieve the function of restraining and guiding the blank a.

Since the specific processing objects of the present invention are strip-shaped blanks such as wood chips or bamboo fan blades, the corresponding main processing parts are in the width and thickness directions, therefore, the execution part 30 includes The first execution unit 31 arranged in succession for processing the thickness direction of the blank a and the second execution unit 32 for processing the width direction of the blank a, each of the execution units includes a blade 33 and a clamping base 34, the The blade 33 is fixed on the clamping base 34 at a certain angle with the processing surface, and the guide path of the guide groove 41 extends inwardly from the feed end of the execution part 30 along its processing direction and ends at the blade of the second execution unit 32 33 at the tip of the tool, as shown in Figure 1-2; in this way, when the pushing part 20 pushes the blank a to the executing part 30, the first executing unit 31 realizes the processing in the thickness direction of the blank a, and then the pushing part 20 continues to push the blank a moves forward, and the second execution unit 32 realizes the cutting of its width dimension, and finally ensures that its processed width and thickness direction dimension meet the subsequent processing requirements.

In order to specifically realize the movement performance of the pushing part 20, the pushing part 20 includes a pushing rod 21 and a limiting unit 22 for guiding the limiting pushing rod 21, and the billeting machine also includes driving the pushing part 20 to guide along the guide groove 41 The power mechanism 50 for reciprocating linear motion in the direction, the power mechanism 50 is a crank rocker mechanism, the rocker end of the power mechanism 50 is connected to the bottom of the push rod 21 of the push part 20 and forms a hinged fit with it, and its crank end is connected to the power At the same time, in order to ensure that the motion cycle of the pushing part 20 meets the actual processing requirements, a gearbox 60 for controlling the action speed of the power mechanism 50 is connected between the power source and the crank end, as shown in FIG. 1 . Because the rocker end of the power mechanism 50 is connected to the bottom of the push rod 21 of the push part 20 and forms a hinged fit with it, when the power source drives the power mechanism 50 to move, the rocker end produces a reciprocating linear motion and transmits its action to the pusher through the hinged fit. The push rod 21 finally realizes the reciprocating linear motion of the push rod.

Considering that the strip-shaped blank a still needs to be manually produced from the blank A, in order to further optimize the structure of the present invention and improve its working efficiency, the blanking machine also includes a cutting tool 71 arranged on one side of the advancing path of the pushing part 20 And the baffle plate 72 that is positioned at its other side, the described cutting tool 71 and the baffle plate 72 jointly constitute the material cutting mechanism, the tip of the knife of the described material cutting tool 71 and the otch are directed to be oppositely set with the pushing direction of the pushing part 20, so The material cutting mechanism is arranged between the feed end of the execution part 30 and the push end of the push part 20 . The actual processing takes bamboo raw material as an example, as shown in Figure 2, when the pushing part 20 returns to the initial position, one side of the semi-cylindrical blank A shown in Figure 4 is leaned against the baffle plate 72, and the pushing part 20 Under the action of the power mechanism 50, the push motion is performed again, and the semi-cylindrical blank A is peeled off the strip-shaped blank a under the dual force of the end of the push rod 21 of the push part 20 and the cutting tool 71, relying on the continuous reciprocation of the push part 20 Pushing, and finally peeling the strip-shaped blank a from the blank A continuously, and processing by the executing part 30 to obtain the finished blank.

In order to ensure that the blank a can enter the feeding end of the execution part 30 accurately and reliably, the blanking machine also includes a material guide piece arranged at the tail end of the cutting mechanism for the transition of the blank a from the tail end of the cutting mechanism to the guide groove 41 80, as shown in Figure 5, the shape of the guide sheet 80 is in the shape of a sheet-shaped curved arc, and the outer side of the arc surface is set towards the cutting mechanism; the guide sheet 80 extends to both sides to fix it on the machine. The wing plate 81 on the working surface of the frame 10 ensures the stability of its material guide sheet 80 during processing.

Further, the pressing part 42 includes a pressing shaft 421 and a rolling bearing unit 422 sleeved on the pressing shaft 421, and the axial direction of the pressing part 42 is set perpendicular to the direction of travel of the blank a, as shown in Figure 1-3 Show. When the blank a passes through the guide sheet 80 and travels toward the execution part 30, the guide groove 41 and the pressing part 42 jointly form a travel channel that restricts its travel direction, so as to ensure that its travel path meets the requirements, and finally ensure that it passes through the execution part. The part 30 is in a suitable processing position during processing, and the selection of the bearing unit 422 avoids the direct dry friction between the blank a and the pressing part 42, which can effectively prolong its service life, thereby ensuring the stable and reliable operation of the machine body.

Considering that the size and shape of bamboo and wood handicrafts are different, the size requirements of the blank a required for it will vary greatly accordingly. The first adjustment unit 91 and the second adjustment unit 92 for fine adjustment in the width direction of the blank a, the first adjustment unit 91 is located at both ends of the pressing shaft 421 of the pressing part 42 and at each execution unit of the execution part 30 , the second adjustment unit 92 is arranged at the baffle plate 72 forming the material cutting mechanism, as shown in Figure 1-3, so as to ensure that the adjustment unit is adjusted accordingly according to the size requirements of the strip blank a to determine its material cutting The width, blank processing thickness and width dimension meet the required requirements, and its adjustment methods can be selected in many ways, such as screw nut adjustment, etc., which will not be repeated here.

Because the present invention relies on the instantaneous momentum of the pushing part 20 to process the blank a, in order to prevent the processed blank a from flying out of the discharge end of the execution part 30 and causing harm to the surrounding personnel, and also in order to facilitate the collection of the processed blank a, the punching The blank machine is provided with a material baffle plate 100 at the discharge end of the execution part 30 to prevent the blank a from splashing, as shown in FIG. 1 . During actual work, a collector can be provided at the lower part of the baffle plate 100. After the blank a hits the baffle plate 100, it will naturally lose its kinetic energy and fall into the collector, which is convenient and quick; meanwhile, as shown in Figure 1, the The blanking machine is provided with an infrared counting unit 110 at the falling point path of the blank a to measure the number of blanks a falling into the collector, which is convenient for later calculation and management.

Here, taking bamboo raw material as example, the overall processing flow of the blank a of the required processing of the present invention is described as follows:

(1), cut the bamboo raw material according to the length requirements of the required processing strip blank a, obtain a certain length of tubular bamboo raw material, and obtain a semi-cylindrical blank A as shown in Figure 4 after half-cutting it;

(2), as shown in Figure 2, when the pushing part 20 is in the initial position, one side of the semi-cylindrical blank A shown in Figure 4 is leaned against the baffle plate 72;

(3), the power mechanism 50 moves and drives the pushing part 20 to perform linear pushing motion, and the semi-cylindrical blank A is under the double application force of the instantaneous impact of the end of the pushing rod 21 of the pushing part 20 and the cutting force of the cutting tool 71. The shape blank a is peeled off from the blank A;

(4), as shown in Figure 2, the push rod 21 of the push part 20 returns to the initial position again, repeats the above-mentioned operation, and strips the strip blank a from the blank A again, and at this moment the strip blank a is initially stripped out in the subsequent strip. The top feeding and lower pressing part 42 of the billet, the working surface of the frame 10 and the guide groove 41 jointly form a channel to advance one station;

(5), repeat the operation as above, the pushing part 20 is constantly moving, and the blank a is continuously peeled off from the blank A, and the strip-shaped blank a stripped at first is processed by each execution unit of the execution part 30 under the top feeding of the subsequent blank , and finally the material is discharged from the discharge end of the execution part 30 and falls into the collector, and the number of processed blank a is calculated by the infrared counting unit 110 located at the falling path of the blank a.
