Description

Technical Field:

[0001] The utility model relates to the technical field of grooving knives, in particular to a pneumatic double-V grooving knife. Background Art:

[0002] At present, the existing V-shaped grooving knives are mainly used to groove materials in a V shape. Their structures are as shown in the patent applications with publication numbers CN219074567U and CN216541044U. The former discloses an electric V-shaped grooving vibrating knife, which installs a blade at the bottom of a rotating cylinder. During operation, a driving mechanism is required to drive the rotating cylinder and the blade to move forward to cut one side of the V-shaped groove, and then return to cut the other side of the V-shaped groove. It takes two round trips to complete the cutting of the V-shaped groove, resulting in a slow cutting speed and low efficiency. The latter discloses a multi-axis horizontal V-shaped grooving machine, which drives two sets of symmetrically arranged grooving knives to move simultaneously through a driving mechanism to cut and groove the material. Although it can complete the cutting of the V-shaped groove at one time, its structure is too complex, the volume is large, the control difficulty is high, and the manufacturing cost is greatly increased.

[0003] In summary, the above problems of the existing V-shaped grooving knives have become technical problems that urgently need to be solved in the industry. Content of the Utility Model:

[0004] The utility model provides a pneumatic double-V grooving knife to make up for the deficiencies of the existing technology, solving the problems of slow cutting speed and low efficiency of the previous single V-shaped grooving knife, and solving the problems of complex structure and too high manufacturing cost of the previous two sets of V-shaped grooving knives.

[0005] The technical solution adopted by the utility model to solve the above technical problems is as follows:

[0006] A pneumatic double-V grooving knife includes a rotating cylinder, a base is connected to the bottom of the rotating cylinder, and two sets of vibrating knife mechanisms are symmetrically installed on both sides of the base. The vibrating knife mechanism includes a linear guide rail obliquely arranged on the side of the base, a tool holder is slidably installed on the linear guide rail, the tool holder is connected to a driving unit installed on the base, a blade is installed at the bottom of the tool holder, and the blades of the two sets of vibrating knife mechanisms are arranged in a V shape.

[0007] A connecting block is provided on the outer side of the upper part of the rotating cylinder.

[0008] The rotating cylinder and the base are fixedly connected by a plurality of screws.

[0009] A reference seam is vertically provided at the center of the base, and the two sets of vibrating knife mechanisms are symmetrically arranged with the reference seam as the center.

[0010] The driving unit is a cylinder.

[0011] The cylinder block of the cylinder is installed in the cylinder groove of the base. A number of bolts pass through the long strip T-shaped groove on the other side of the base and are connected to the cylinder block of the cylinder for fixation. The piston rod of the cylinder is fixedly connected to the tool holder.

[0012] An air inlet passage is provided in the rotating cylinder and the base. An air inlet nozzle is provided at the top of the rotating cylinder, and two air outlet nozzles are provided at the side of the base. The two air outlet nozzles are respectively connected to the two cylinders through pipelines.

[0013] A sealing ring is provided between the rotating cylinder and the base for sealing.

[0014] Adopting the above scheme, the utility model has the following beneficial effects:

[0015] By symmetrically installing two sets of vibrating knife mechanisms on both sides of the base at the bottom of the rotating cylinder, and the blades of the two sets of vibrating knife mechanisms are arranged in a V shape, the integration of the two sets of vibrating knife mechanisms is realized. The cutting work of the V-shaped groove can be completed by one-way movement. The cutting speed is fast, the efficiency is high, and the structure is simple, the volume is small, the control difficulty is small, and the manufacturing cost is low. Description of the drawings:

[0021] To clearly illustrate the technical features of this scheme, the utility model will be elaborated in detail below through specific embodiments and in conjunction with its drawings.

[0022] Combined as Figures 1-4In the illustrated embodiment, a pneumatic double-V grooving tool includes a rotating cylinder 1. A base 2 is connected to the bottom of the rotating cylinder 1. Two sets of vibrating knife mechanisms are symmetrically installed on both sides of the base 2. The vibrating knife mechanism includes a linear guide rail 3 obliquely arranged on the side of the base 2. A tool holder 4 is slidably installed on the linear guide rail 3. The tool holder 4 is connected to a driving unit installed on the base 2. A blade 5 is installed at the bottom of the tool holder 4. The blades 5 of the two sets of vibrating knife mechanisms are arranged in a V shape.

[0023] A connecting block 6 is provided on the outer side of the upper part of the rotating cylinder 1 and is connected to an external fuselage through the connecting block 6 to drive the rotating cylinder 1 to rotate.

[0024] The rotating cylinder 1 and the base 2 are fixedly connected by a plurality of screws.

[0025] A reference slot 7 is vertically provided at the center position of the base 2. The two sets of vibrating knife mechanisms are symmetrically arranged with the reference slot 7 as the center. The reference slot 7 can be used as a reference benchmark during the initial debugging of the blade position.

[0026] The driving unit is a cylinder 8.

[0027] The cylinder block of the cylinder 8 is installed in a cylinder groove of the base 2. A plurality of bolts pass through a long strip-shaped T-shaped groove 9 on the other side of the base 2 and are connected to the cylinder block of the cylinder 8 for fixation. The piston rod of the cylinder 8 is fixedly connected to the tool holder 4. The position of the cylinder 8 in the cylinder groove can be adjusted and fixed by bolts after the position is adjusted.

[0028] An air inlet passage 10 is provided inside the rotating cylinder 1 and the base 2. An air inlet nozzle 11 is provided at the top of the rotating cylinder 1. Two air outlet nozzles 12 are provided on the side of the base 2. The two air outlet nozzles 12 are respectively connected to the two cylinders 8 through pipes. Gas can enter the air inlet passage 10 from the air inlet nozzle 11 and then be supplied to the two cylinders 8 respectively through the air outlet nozzles 12, saving connection pipes and simplifying the air path connection structure.

[0029] A sealing ring 13 is provided between the rotating cylinder 1 and the base 2 for sealing to prevent gas from leaking out between the rotating cylinder 1 and the base 2.

[0030] Working principle:

[0031] During operation, the external fuselage drives the rotating cylinder 1 to translate through the connecting block 6. The rotating cylinder 1 drives two sets of vibrating knife mechanisms to translate through the base 2. The two blades 5 simultaneously perform grooving cutting on the material. At the same time, the cylinder 8 is activated, and the cylinder 8 drives the tool holder 4 to reciprocate along the linear guide rail 3. The tool holder 4 then drives the blade 5 to reciprocate, causing the blade 5 to perform grooving cutting while translating and vibrating. After the two blades 5 cooperate with each other, the cutting of the V-shaped groove can be completed by advancing unidirectionally once. The cutting speed is fast and the efficiency is high. When the grooving in one direction is completed, the external fuselage drives the rotating cylinder 1 to turn, and the rotating cylinder 1 drives two sets of vibrating knife mechanisms to turn for cutting the V-shaped groove in the other direction.

[0032] The above specific implementation manners cannot be used as a limitation on the protection scope of the present utility model. For those skilled in the art of this technology, any alternative improvement or transformation made to the implementation manners of the present utility model falls within the protection scope of the present utility model.
