Description

Blank positioner

Technical Field

The utility model relates to the technical field of material cutting processing, in particular to a cutting positioning device.

Background

The existing doors and windows are processed by adopting an angle splicing process, for example, one door and window needs to adopt four strip-shaped sections, two ends of each strip-shaped section are provided with 45-degree oblique angles, the four strip-shaped sections are connected end to enclose a rectangular frame, and two 45-degree oblique angles of two adjacent strip-shaped sections are spliced, so that the spliced parts of the two adjacent strip-shaped sections are in a right-angle shape.

When processing a strip-shaped section with a 45-degree oblique angle, the strip-shaped raw material needs to be cut into multiple sections, and simultaneously, the two ends of each section of the material are cut to obtain the 45-degree oblique angle, so that the strip-shaped section is formed. Since the 45 bevel angle at both ends of each piece of material is symmetrically distributed, this results in that the bevel angle shape of the end of the strip of raw material that is cut after each piece of material is cut is not identical to the bevel angle shape of the next piece of material, which requires re-cutting the end of the strip of raw material to form a 45 bevel angle with the target orientation.

Two main factors are considered when re-cutting the end of the strip of raw material: the amount of cut and the bevel shape after cutting along the length of the stock material, wherein the portion of the stock material cut from the end of the elongated stock material is often referred to as the stub bar. In the current production process, operators need to visually control the cutting amount, namely, the length of the stub bar, so that the loss of the stub bar is up to 0-5% and 2% saw loss is caused when the material is cut in order to ensure that the bevel angle shape after cutting meets the requirements. Therefore, the current production process has large dependence on the technical capability of operators, and the cutting effect and the material utilization rate are difficult to be considered.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

The present utility model will be further described in detail below with reference to the drawings and detailed description for the purpose of enabling those skilled in the art to better understand the aspects of the present utility model.

Referring to fig. 1 to 3, fig. 1 is a diagram showing a cutting effect of a cutter on a workpiece; fig. 2 is a schematic structural diagram of a blanking positioning apparatus according to an embodiment of the present utility model; fig. 3 is a schematic diagram illustrating installation of a blanking positioning device and a to-be-blanked according to an embodiment of the present utility model.

Referring to fig. 1 and 2, the present utility model provides a blanking positioning device, which includes a first positioner and a second positioner; the first positioner is provided with a cutting joint 1 for the cutter to move along the joint, for example, the cutting joint 1 extends along oblique lines, and the cutter can be embedded into the cutting joint 1 and move in the cutting joint 1 along the tracks shown by the oblique lines so as to cut a material to be cut 01; the second positioner is provided with a positioning block 2 and a driver 3, and the driver 3 is connected with the positioning block 2 and can drive the positioning block 2 to be close to and far away from the first positioner so as to block and avoid the end part of the material to be cut 01.

In this embodiment, the cutter embedded in the slit 1 is used for cutting the material 01 to be cut, and thus the mounting position of the material 01 to be cut is close to the first positioner, for example, the material 01 to be cut is abutted against the first positioner or is close to the first positioner. Because the mounting position of the material to be cut 01 is close to the first positioner, when the driver 3 drives the positioning block 2 to be close to the first positioner, the positioning block 2 is gradually close to the material to be cut 01 and blocks the end part of the material to be cut 01, so that the material to be cut 01 is attached to the material to be cut 01, otherwise, when the driver 3 drives the positioning block 2 to be far away from the first positioner, the positioning block 2 is gradually far away from the material to be cut 01 until the end part of the material to be cut 01 is separated.

The driver 3 may be an electric push rod or a pneumatic push rod, and the positioning block 2 may be a stub bar 011 obtained after a certain cutting.

The blanking positioning device provided by the embodiment can be applied to the blanking operation of the door and window frame and is used for cutting the long-strip-shaped work material into door and window frame strips with oblique angles at two ends. The long strip-shaped work material can be cut into a plurality of door and window frame strips, the oblique angles at the two ends of any door and window frame strip are symmetrically distributed, and when the long strip-shaped work material is continuously cut, the end part of the long strip-shaped work material needs to be cut again, so that the end part of the long strip-shaped work material forms the oblique angle with the target orientation. The blanking positioning device provided by the embodiment adopts the cutter moving along the kerf 1 to cut the end part of the strip-shaped work material by an oblique angle, and adopts the second positioner to position the mounting position of the end part of the strip-shaped work material, so that the cutter moving along the kerf 1 can cut the end part of the strip-shaped work material at a designated position.

Therefore, the cutting positioning device provided by the embodiment utilizes the first positioner to restrict the cutting position of the cutter, and utilizes the second positioner to restrict the position of the to-be-cut material 01, namely, the long-strip-shaped work material, relative to the cutter, so that the cutter is ensured to cut at the appointed position of the end part of the long-strip-shaped work material, the situation that the cutting position of the cutter is too far forward to cause that the qualified bevel angle cannot be obtained by cutting is avoided, and the situation that the cutting position of the cutter is too far backward to cause that part of the long-strip-shaped work material is cut and abandoned is avoided. Wherein, near the front refers to near the end of the long strip work material, near the back refers to near the middle of the long strip work material along the length direction.

When the blanking positioning device provided by the embodiment is used for cutting the oblique angle of the long-strip-shaped work material, firstly, before cutting, the positioning block 2 of the second positioner is moved to the end part of the long-strip-shaped work material, is tightly attached to the end part of the long-strip-shaped work material, and accurately limits the space position of the end part of the long-strip-shaped work material, so that the relative positions of the long-strip-shaped work material and the cutter are limited, and the cutter is accurately aligned to the appointed position of the long-strip-shaped work material; then, the cutter is started to move along the cutting seam 1, the cutter gradually approaches the long-strip-shaped work material and cuts at a designated position of the long-strip-shaped work material, and the end part of the long-strip-shaped work material is enabled to present a specific oblique angle by cutting off the redundant material at the end part of the long-strip-shaped work material. The second positioner can remove the positioning block 2 at the stage from the moment when the cutter is set to the moment when the cutter is cut, and can also remove the positioning block 2 after the cutter is cut.

In summary, the cutting positioning device provided by the utility model can accurately position the cutter and the material to be cut 01, not only can ensure that the cutter cuts the material to be cut 01 along a specific track, but also can ensure that the cutter cuts at a designated position of the material to be cut 01, and can ensure the processing quality of products and consider the utilization rate of materials by improving the precision of the cutting position.

The blanking positioning device provided by the utility model is further described below with reference to the accompanying drawings and the embodiments.

In some embodiments, the blanking positioning apparatus further includes a mounting seat 4, and the first positioner and the second positioner are both disposed on the mounting seat 4; the driver 3 is slidably connected with the mounting seat 4, and the sliding direction of the driver and the mounting seat is parallel to the feeding direction of the material to be cut 01. The feeding direction of the material to be cut 01 refers to a moving direction when the material to be cut 01 is driven to move in order to cut the same material to be cut 01 for a plurality of times.

Although the sawing is unavoidable when cutting the material 01 to be cut, that is to say the size of the sawing zone 012 corresponds to the knife, if the knife is not changed, the size of the sawing zone 012 is also unchanged. However, in the above embodiment, the driver 3 of the second positioner is slidably connected with the mounting seat 4, and an operator can adjust the relative position between the second positioner and the first positioner according to specific process requirements, for example, if the feeding direction of the to-be-cut material 01 is distributed along the X axis, the driver 3 and the mounting seat 4 slide relatively along the X axis, at the same time, the driver 3 of the second positioner can drive the positioning block 2 to move along the Y axis, and the length of the material loss of the stub bar 011 is controlled by adjusting the distance between the positioning block 2 and the kerf 1.

Usually, when a cutter is used to cut an oblique angle with the same size at the end of the material to be cut 01, the base of the driver 3 and the mounting seat 4 are fixed relatively, and the telescopic rod of the driver 3 drives the positioning block 2 to move along the Y-axis direction. When the cutter is adopted to cut oblique angles with different sizes of the material 01 to be cut, the base of the driver 3 can be slid along the mounting seat 4, so that the mounting seat 4 and the driver 3 can relatively move along the X axis, and the positioning effect of the positioning block 2 on the end part of the material 01 to be cut is adjusted.

When the positioning block 2 moves along the Y-axis direction, the positioning block 2 approaches and separates from the first positioner and the slit 1 thereof, for example, when the positioning block 2 moves toward the positive direction of the Y-axis direction, the positioning block 2 approaches the first positioner and the slit 1 thereof, whereas when the positioning block 2 moves toward the negative direction of the Y-axis direction, the positioning block 2 separates from the first positioner and the slit 1 thereof.

In some embodiments, the mount 4 may include a base 41 and a standing baffle 42 provided at an edge of the base 41; the standing board 42 is provided at the edge of the base 41, and can serve as a mounting base for the actuator 3, for example, the actuator 3 is slidably connected to the standing board 42. The standing plate 42 may also serve as a plate for the base 41, and prevent cutting scraps from splashing outside the plate.

In order to facilitate the connection between the mounting seat 4 and the driver 3, the second positioner further comprises a clamping piece 5; one end of the clamping piece 5 is fixed on the driver 3, the other end of the clamping piece 5 is provided with a sleeve-setting baffle 42 and is connected with the standing baffle 42 in a sliding manner, for example, the clamping piece 5 can be sleeved on the edge of the upper plate body of the standing baffle 42 and can slide along the edge of the upper plate body. It can be seen that the clip 5 is provided between the driver 3 and the standing board 42, and can realize the sliding connection of the driver 3 and the standing board 42. Generally, the vertical baffle plate 42 is provided with scales distributed along the sliding direction of the clamping member 5, and can be used for calibrating the relative sliding distance between the driver 3 and the vertical baffle plate 42, so that an operator can accurately adjust the relative positions of the driver 3 and the mounting seat 4 according to specific process requirements.

In some embodiments, the blanking positioning device provided by the utility model is provided with a feed inlet, and the to-be-blanked material 01 enters the blanking positioning device from the feed inlet; at the same time, the base 41 has a guide surface which guides the cut-out to slide down, and which is upwardly distributed and inclined in a direction away from the feed opening.

When the cutter is used for cutting the material to be cut 01, the material to be cut 01 can be divided into three parts: waste stub bars 011, finished product lumps and work material which is not cut. Still taking the example of the blank positioning device for processing door and window frame strips, the work material refers to the long-strip work material mentioned above, the finished product block refers to the door and window frame strips mentioned above, and the waste head 011 refers to a cut-away portion removed for cutting out an oblique angle with a target orientation and magnitude at the end of the long-strip work material. When the cutter finishes the cutting operation of one finished product block, a waste head 011 and a finished product block are generated, and the waste head 011 and the finished product are separated from the work material which is not cut.

In order to avoid accumulation of the scrap head 011 and the final product block at the position of the first positioner and the slit 1 thereof, the above embodiment employs a guide surface to guide the scrap head 011 and the final product block to slide down. The material guiding surface is upwards distributed, and the waste head 011 and the finished product material block drop downwards on the material guiding surface after being separated from the work material which is not cut; the guide surface is inclined in a direction away from the feed inlet, and the waste head 011 and the finished product block falling on the guide surface can slide downwards along the inclined plane where the guide surface is located, so that the waste head and the finished product block are away from the feed inlet. The material guiding surface can guide the waste material head 011 and the finished product material block away from the feeding hole, so that the waste material head 011 and the finished product material block are prevented from being continuously piled up at the feeding hole, and the continuous cutting of the cutting positioning device is facilitated.

Referring to fig. 2 and 3, the blanking positioning device is applied to the blanking operation of door and window frames, because the directions of oblique angles at two ends of a single door and window frame strip are different, for example, the oblique angles at two ends of the same door and window frame strip are symmetrically distributed, two first positioners and corresponding cutters can be adopted to respectively cut strip-shaped work materials, and the distribution tracks of the kerfs 1 of the two first positioners can be symmetrically distributed and exactly correspond to the oblique angles at two ends of the same door and window frame strip. In addition, the two first positioners are distributed at intervals along the feeding direction of the material to be cut 01, the distance between the two first positioners is equal to the target length of the finished product block, and the two cutters can synchronously move along the slits 1 of the two first positioners to realize cutting, and can also sequentially move along the slits 1 of the two first positioners to realize cutting.

In addition, referring to fig. 2 and 3, in the blanking positioning apparatus, the first positioner further includes a cutter positioning plate 6, and the slit 1 is specifically an inclined slit provided in the cutter positioning plate 6; at the same time, the side of the positioning block 2 facing the tool positioning plate 6 is in an angle shape, and when the positioning block 2 approaches to and contacts the first positioner, the angle of the positioning block 2 is abutted against the tool positioning plate 6. For the positioning block 2, the tool positioning plate 6 can assist in positioning the positioning block 2; for the cutter positioning plate 6, the angle of the positioning block 2 is attached to the cutter positioning plate 6, so that the positioning block 2 can be prevented from interfering with the movement of the cutter in the cutting joint 1 and interfering with the sight of an operator.

Furthermore, in some embodiments, the first positioner further comprises a knife positioning plate 6, the slit 1 being in particular an oblique slit provided in the knife positioning plate 6; at the same time, the side of the positioning block 2 facing the cutter positioning plate 6 is in an angle shape, that is, when the positioning block 2 approaches to and is tightly attached to the first positioner, the angle of the positioning block 2 is attached to the cutter positioning plate 6, at this time, the positioning block 2 can also be tightly attached to the end of the to-be-cut material 01, so that the position of the end of the to-be-cut material 01 is accurately limited, and the precision of the cutting position of the cutter at the to-be-cut material 01 is ensured.

The angle of locating piece 2 laminating cutter locating plate 6, to locating piece 2, cutter locating plate 6 can be used for the auxiliary positioning locating piece 2, and to cutter locating plate 6, the angle of locating piece 2 can avoid interfering the cutting path of cutter in joint 1, also can avoid interfering the realization of operating personnel.

In the above embodiment, the positioning block 2 is provided with the positioning groove for embedding the end of the material to be cut 01, that is, the positioning groove is disposed on the positioning block 2 and faces the material to be cut 01, when the end of the material to be cut 01 is attached to the positioning block 2, the end of the material to be cut 01 is embedded into the positioning groove, so that the positioning accuracy of the end of the material to be cut 01 of the positioning block 2 can be improved. In this embodiment, the positioning block 2 takes the bottom surface of the positioning groove as a positioning surface for accurately defining the position of the end of the material 01 to be cut.

In summary, the blanking positioning device provided by the utility model can be improved on conventional non-automatic equipment and semi-automatic equipment, can automatically and accurately control the loss of the stub bar 011, ensure the cutting effect, completely eliminate the artificial visual loss, reduce the operation difficulty and improve the material utilization rate. In addition, compared with full-automatic equipment, when the blanking positioning device provided by the utility model is applied to non-automatic equipment and semi-automatic equipment, the improvement cost is low, and the blanking positioning device can be widely applied to most factories in China at present.
