The rounding machine is bad in working condition, the hydraulic drive is used, the impact resistance and the durability are good, but the uniform rotary cutting of the single plates needs the hydraulic drive element to realize large-range accurate stepless speed regulation, and the difficulty is high. At present, the prior art is mainly realized by adopting an electric stepless speed regulation driving feed screw rod, and has the defect of poor durability of equipment which does not resist impact. OSB veneered flakeboard shaving production relies on long wood slicing equipment, which is expensive, and has low material utilization rate, and generates ultra-three-piece crushed aggregates. The rotary-cut shavings are used for replacing by individual manufacturers, the utilization rate is as high as 95 percent, the sheet shape is good and controllable, the process difficulty of the rotary-cut shavings replacing long-material slicing shavings is that rough processing of the wood, namely, rounding of the wood, is realized, the basic requirement of the equipment is to obtain uniform shavings with the thickness of less than 0.7, the existing hydraulic rounding machine cannot meet the requirement, the modified numerical control rotary-cut rounding machine can meet the requirement on the thickness but does not have poor impact resistance and durability, and the prior art also lacks a rounding device which can meet the requirements on the shavings, is durable and has high efficiency.

Disclosure of Invention

The invention aims to provide a cam interlocking hydraulic drive rotary cutting rounding machine, which overcomes the defect that in the prior art, a rounding device which can meet the requirements of wood shavings and is durable and efficient is absent.

The invention is realized by adopting the following technical scheme: the cam interlocking hydraulic drive rotary-cut rounding machine comprises a rack, wherein a cutter holder, a single-roller seat and a double-roller seat are arranged on the rack, a single roller is arranged on the single-roller seat, double rollers are arranged on the double-roller seat, a rocker mandrel and a cam shaft penetrating through the rack are arranged on the rack, two rocker arms are symmetrically hinged to two ends of the rocker mandrel, a connecting rod is hinged to the rocker arms, the connecting rod is hinged to a connecting rod seat fixed on the double-roller seat or the cutter holder, an oil cylinder seat is fixedly arranged on the rack, an oil cylinder is hinged between the oil cylinder seat and the rocker arms, two cams are symmetrically and fixedly arranged at two ends of the cam shaft, a roller is arranged on each rocker arm, and the roller is attached to the outer.

Further, the cam outer edge shape adopts a continuous irregular spiral.

Furthermore, the oil cylinder is connected with an overflow valve.

Furthermore, the two rocker arms which are symmetrically arranged are fixedly connected with a synchronous connecting support.

Compared with the prior art, the invention has the beneficial effects that:

the invention realizes the independent control and the integration of the force and the speed of the feed system, realizes the precise stepless speed regulation in a larger range, has the speed regulation accuracy and reliability of the mechanical cam superior to numerical control, simultaneously has simple and effective control of hydraulic pressure on the pressure, has buffering and good impact resistance effect, and improves the durability of the machine.

Detailed Description

The invention will be further explained with reference to the drawings.

As shown in fig. 1, the cam interlocking hydraulic drive rotary cutting and rounding machine of the present invention includes a frame 1, a tool apron 2, a single roller seat 3 and a double roller seat 7 are arranged on the frame 1, a single roller 4 is arranged on the single roller seat 3, and a double roller 6 is arranged on the double roller seat 7. The machine frame 1 is provided with a rocker arm core shaft 13 and a cam shaft 16 which are positioned below the double-roller seat 7 and penetrate through the machine frame 1, two rocker arms 10 are symmetrically hinged to two ends of the rocker arm core shaft 13, a connecting rod 8 is hinged to the rocker arms 10, the connecting rod 8 is hinged to a connecting rod seat 9 fixed on the double-roller seat 7 or the cutter holder 2, and the rocker arms 10, the connecting rod 8 and the double-roller seat 7 form a rocker slider mechanism. One of the double-roller seat 7 and the tool apron 2 can do reciprocating linear motion along the track on the frame 1 to realize driving and reversing, when the double-roller seat 7 can do reciprocating linear motion along the track on the frame 1, the connecting rod 8 is hinged with the connecting rod seat 9 fixed on the double-roller seat 7, and when the tool apron 2 can do reciprocating linear motion along the track on the frame 1, the connecting rod 8 is hinged with the connecting rod seat 9 fixed on the tool apron 2. An oil cylinder base 12 is fixedly arranged on the frame 1, an oil cylinder 11 is hinged between the oil cylinder base 12 and the rocker arm 10, two cams 14 are symmetrically and fixedly arranged at two ends of a cam shaft 16, a roller 15 is arranged on the rocker arm 10, the roller 15 is attached to the outer edge of the cam 14, and the roller 15, the cam 14 and the rocker arm 10 form a cam swing mechanism together.

The shape of the cam 14 is strictly designed according to the rotary cutting process requirements and the mechanism parameters, the rotary cutting thickness of the cam 14 is linearly related to the rotary cutting linear speed, the rotary cutting thickness does not change along with the rotary cutting diameter, the control procedure is simplified, and the fault is low and the precision is high. The cam swing mechanism is used as a passive speed limiting and regulating device, when the working feed suddenly impacts, the roller 15 and the cam 14 can be separated from contact and force is removed, and then the working feed is immediately switched into, so that the inconvenience caused by overload fault parking of the frequency converter is avoided.

Further, the outer edge shape of the cam 14 is a continuous irregular spiral.

Further, the oil cylinder 11 is connected with an overflow valve. When the working and withdrawing processes, the oil cylinder 11 is always used as the driving force for the swing of the rocker arm 10, namely the movement of the double-roller seat 7 or the cutter holder 2, so that the set pressure and the back overflow when sudden impact are achieved, and the buffering effect is achieved.

Furthermore, two rocker arms 10 which are symmetrically arranged are fixedly connected with a synchronous connecting support, and the two rocker arms 10 are connected into a whole so as to ensure synchronous feed or withdrawal of the cutters at two sides.

The working principle of the invention is as follows: when the cam 14 rotates anticlockwise, the oil cylinder 11 pushes the rocker arm 10 to swing anticlockwise, the connecting rod 8 drives the double-roller seat 7 or the tool holder 2 which can do reciprocating linear motion along the track on the rack 1 to move forward, and the cam 14 and the rocker arm 10 change the rotating direction to move back.
