Description

Technical Field

[0001] The utility model relates to the field of wood processing equipment, and particularly relates to a wood board cutting machine. Background Art

[0002] In furniture factories, a large amount of materials are processed by using a cutting machine to cut boards into workpiece blanks. Due to the need to clamp the boards, at least one to two workpiece woods are wasted from one piece of raw material, resulting in relatively large waste or a certain cost for recycling, thus increasing the production cost.

[0003] In the existing processing method, the wood board is placed on the clamp in front of the feeding rack, the moving clamp head presses down to clamp it, and the wood board is pushed by the feeding rack to the position of the cutting tool for cutting and processing into workpiece blanks of various shapes. Since the static clamp head of the clamp is fixed relative to the wood board, the wood of the clamped part cannot be cut, leaving a large piece of wood. This wood can only be recycled and synthesized for secondary use or treated as waste. As a result, material waste or processing cost increases.

[0004] In the prior art, due to clamping the wood board, the wood material of the clamped part cannot be processed, so the tail material with a relatively large production area cannot be utilized and is directly treated as waste; directly wasting wood increases the production cost. For some tail materials with a relatively large production area, many times, a flat side surface is processed from multiple pieces of tail materials, and then the tail materials are synthesized into large-area boards by using the plywood process. The process of processing the tail materials and then synthesizing them into large boards not only wastes materials but also increases the cost of using the remaining materials.

[0021] The following further elaborates on the utility model of the present application in detail in combination with the accompanying drawings and specific embodiments. For a clear and complete description of the technical solution, the following embodiments are selected for illustration; based on the content recorded in the present application, other embodiments obtained without creative labor fall within the protection scope of the present utility model.

[0022] In the following embodiments, it should be noted that the orientation or positional relationships such as "upper", "lower", "left", "right", "inner", "outer", "top / bottom", etc. in the terms are all based on the orientation or positional relationships shown in the accompanying drawings. It is only for the convenience of clearly describing this embodiment, rather than indicating or implying that the device or element referred to must have a specific orientation, so it cannot be understood as a limitation to the present application.

[0023] As Figures 1-5 shown, a specific embodiment of the present utility model is a wood plate cutting machine, which includes a processing frame 3 and a pushing mechanism arranged on the processing frame 3 for pushing the wood plate to move back and forth. The pushing mechanism includes a pushing frame body 1 and a plate clamping device 2 installed on the pushing frame body 1. The plate clamping device 2 is at least two, and each plate clamping device 2 can independently move in the same direction as the wood plate relative to the pushing frame body.

[0024] At least one group of horizontal sliding rails 102 is arranged on the pushing frame body 1 along the moving direction of the wood plate. The plate clamping devices 2 are movably installed on the horizontal sliding rails 102 in a one-to-one correspondence. Each plate clamping device 2 is provided with a corresponding horizontal power mechanism 4, and the horizontal power mechanism 4 can drive the plate clamping device 2 to slide back and forth horizontally along the horizontal sliding rail 102.

[0025] To facilitate the overall horizontal movement of the pushing frame body, installation grooves 101 equivalent to the number of horizontal sliding rails (one installation groove corresponds to one group of horizontal sliding rails) are arranged on the pushing frame body 1, and the horizontal sliding rails 102 are installed in the installation grooves 101 in a one-to-one correspondence. The pushing frame body 1 and the plate clamping device 2 are integrally designed to facilitate the overall horizontal movement. Each group of horizontal sliding rails can be one rail, two rails, or three rails.

[0026] The plate clamping device 2 is composed of a clamping frame body 201, a moving chuck 202, a static chuck 203 and a clamping power mechanism 204. The moving chuck 202 is hinged inside the front end of the clamping frame body 201. There are at least two static chucks 203 fixedly arranged below the front end of the clamping frame body 201. The clamping power mechanism 204 is fixedly installed at the tail of the clamping frame body 201. The clamping power mechanism 204 can drive the moving chuck 202 to rotate close to or away from the static chuck 203. The horizontal power mechanism 4 is a telescopic cylinder; the clamping power mechanism 204 is an oil cylinder. Driven by the horizontal power mechanism, the plate clamping device can move forward and backward relative to the feeding frame body alone. The static chuck, the clamping power mechanism and the moving chuck arranged below the clamping device can cooperate with each other to achieve the clamping function. When the static chuck extends to the specified position, the clamping power mechanism can drive the moving chuck to clamp the wood; when it is necessary to process the clamping position, the clamping power mechanism can drive the moving chuck to release the wood, and after the static chuck retracts.

[0027] In order to better drive the clamping device to move smoothly, the clamping frame body 201 is of a U-shaped frame structure. Sliding wing plates 206 are arranged on both sides of the clamping frame body 201. The sliding wing plates 206 are fixedly installed on both sides of the clamping frame body 201. The clamping frame body 201 is of a hollow structure. The sliding wing plates 206 are provided with sliding grooves corresponding to the horizontal slide rails 102.

[0028] In order to reasonably allocate space for installing the clamping power mechanism, the clamping power mechanism is installed at the top end of the tail of the clamping frame body 201 through fixing bolts. The clamping power mechanism 204 forms an angle of 75 - 90° with the horizontal plane; a top cover plate 205 that fits the clamping frame body 201 is arranged on one side of the clamping power mechanism 204.

[0029] In order to facilitate clamping of the wood, the front end of the clamping frame body 201 is of a slope-shaped structure, and a guiding plate 207 with a V-shaped opening is further arranged inside the front end of the clamping frame body 201.

[0030] In order to make the clamping of the wood more stable, the number of static chucks 203 below the front end of the clamping frame body 201 is two. The static chucks 203 are provided with corrugated tooth structures, and an anti-slip soft chuck is fixedly installed at the front end of the moving chuck 202.

[0031] Embodiment 1

[0032] As Figure 3, the processing rack 3 is provided with a first horizontal moving pair 5 in the Y direction and a second horizontal moving pair 6; the second horizontal moving pair 6 is provided with a horizontal carriage 7; an upper power spindle 8 and a lower power spindle 9 are arranged on the horizontal carriage 7, and cutting tools 10 are arranged on the two power spindles. The horizontal carriage 7 realizes horizontal movement in the X direction relative to the wooden board material to be processed under the start of the servo motor; a material pushing frame body 1 is arranged on the second horizontal moving pair 6, and four plate clamping devices for a cutting machine are arranged on the material pushing frame body 1. The horizontal power mechanisms correspond to the plate clamping devices one by one. The horizontal power mechanism can drive the plate clamping device to realize forward and backward movement relative to the material pushing frame body separately. Under the control of the driving program, the X and Y carriages of the wooden board realize relative movement to the tool in the XY plane to realize the processing of blank parts of various shapes. When the tool needs to cut at a certain clamping device position, the clamping power mechanism at this position first loosens the chuck and retreats away from the wooden board area to enable the cutting tool to smoothly cut this position. After cutting this position is completed, the moving chuck advances to the original clamping position and clamps the workpiece to keep the workpiece stable, facilitating the subsequent chuck to automatically give way to the cutting tool. Finally, the cutting processing work of the whole process is perfectly realized.

[0033] The above is only the preferred embodiment of the present invention and is not intended to limit the present invention. Any minor modifications, equivalent replacements, and improvements made to the above embodiments based on the technical essence of the present invention shall be included in the protection scope of the technical solution of the present invention.
