Description

Technical Field

[0001] The present application relates to the field of plate bending, and in particular to a multi-angle bending machine for a refrigerator cabinet. Background Art

[0002] A freezer is a device that preserves food, medicine and other items at low temperatures. It is widely used in various fields of today's life. The basic function of a freezer is to refrigerate and keep the inside of the box at an appropriate low temperature. It is usually composed of a freezer body and a refrigeration system installed in the body. In order to ensure the durability and aesthetics of the freezer body, the freezer body in the existing technology is usually made of stainless steel sheets.

[0003] When processing and producing refrigerator cabinets, it is usually necessary to bend the stainless steel sheets according to the design dimensions of the refrigerator cabinets. The bending machines in the prior art usually adopt the method of pressing down the die head to achieve the bending of the stainless steel sheets. In actual operation, the stainless steel sheets will be warped along the bending position due to the influence of bending. When multiple bends at a relatively close distance are required, the stainless steel sheets will extend above the die head after the previous bend. At this time, the lifting unit arranged above for driving the die head to move up and down will block the multi-angle continuous bending of the stainless steel sheets, resulting in the inability to achieve multi-angle continuous bending at a relatively close distance, affecting its processing convenience.

[0004] To this end, we propose a multi-angle bending machine for a refrigerator cabinet to solve some of the problems existing in the above-mentioned prior art. Summary of the Invention

The two corresponding front and rear connecting rods are hinged to each other at their ends close to each other, and the hinge point is located directly below the central axis of the bending die head. A pressure block for pressing the connecting rod is fixedly installed at the bottom of the cross bar.

[0009] Furthermore, the pressing block is arranged on the left side of the bending die head, the pressing block is located directly above the hinge point between the front and rear connecting rods, and the bottom of the pressing block is arranged as a right-angle structure.

[0010] Furthermore, the top of the machine is supported under the bracket, and a limiting groove is opened in the middle position of the left and right sides of the machine, which is located directly below the hinge point between the front and rear connecting rods, and the bottom angle of the limiting groove is set to a right-angle structure that matches the flipping trajectory of the connecting rod.

[0011] Furthermore, a plurality of transversely arranged rollers are rotatably mounted inside the bracket. The plurality of rollers are evenly distributed inside the bracket from front to back, and the outer end walls of the rollers are wrapped with a rubber layer.

[0012] Furthermore, sliding sleeves are slidably installed on both the left and right sides of the top of the bracket, and a vertically set limit plate is fixedly installed on the side of the sliding sleeve close to the center of the bracket.

[0015] Compared with the existing technology, the advantages of this application are:

[0016] 1. The present application installs the supporting column and the electric lifting assembly for controlling the lifting of the bending die head on the left side, so that there is no other structure above the bending die head, so the folding of the stainless steel sheet during the bending process will not be blocked, and the bending operation can be performed continuously at multiple adjacent positions.

[0018] 3. By rotating the bracket to the front and rear sides of the bending table and fixing the pressure block at the bottom of the cross bar to press the connecting rod, the bracket and the stainless steel sheet can be tilted synchronously during the bending operation.

By wrapping the rubber layer on the outer end wall of the roller, the contact friction resistance between the roller and the stainless steel sheet can be effectively improved, thereby effectively improving the stability of the stainless steel sheet during the movement and adjustment process.

[0020] 5. By sliding the sleeves on the left and right sides of the top of the bracket, the positions of the left and right sleeves and their distance can be adjusted. The stainless steel sheet to be bent can be positioned with the help of the limit plates on the left and right sleeves, which is conducive to ensuring the accuracy and stability of the stainless steel sheet during the bending process.

[0021] 6. By projecting the light beam emitted from the groove onto the stainless steel sheet, a striking light marking line is formed, which helps to assist the staff to quickly correct the bending position, thereby effectively ensuring the stability and accuracy of the stainless steel sheet during the bending process.

[0022] 7.

DETAILED DESCRIPTION

[0036] The embodiments will be combined with the drawings in the specification to clearly and completely describe the technical solution of this application. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making any creative work shall fall within the scope of protection of this application.

[0037] Example 1:

[0038] The present invention provides a multi-angle bending machine for refrigerator cabinets. Figure 1 - Figure 11 , including a machine 1, a horizontally arranged bending table 101 is fixedly installed in the middle position of the top of the machine 1, and a V-shaped forming groove is opened on the top of the bending table 101, and the bottom angle of the forming groove is set to 90°, a column 2 is fixedly installed on the left side of the bending table 101 on the top of the machine 1, and a vertically arranged electric lifting component 201 is installed inside the column 2, and a horizontally arranged cross bar 202 is fixedly installed on the lifting end of the electric lifting component 201, and a bending die 203 located directly above the forming groove is fixedly sleeved on the outer side of the cross bar 202, and the bottom of the bending die 203 is adapted to the internal size of the forming groove, a horizontally arranged first electromagnet 3 is fixedly installed on the bottom of the bending table 101, and a plurality of horizontally distributed second electromagnets 301 are fixedly installed inside the cross bar 202, and the first electromagnet 3 and the second electromagnet 301 are magnetically attracted to each other after being energized.

[0039] During the use of the device, the staff connects the device to an external power supply so that the external power supply provides power support for the device. Then, the staff can control the device to be powered on and start. The staff places the stainless steel sheet used to process the refrigerator cabinet on the top of the bending table 101 and adjusts the position of the stainless steel sheet so that the position to be bent is directly below the bending die 203. Then, the staff controls the device to drive the lifting end of the electric lifting assembly 201 to move downward, driving the cross bar 202 and the bending die 203 on the cross bar 202. Moving downward, the bottom of the bending die 203 acts on the stainless steel sheet, and cooperates with the forming groove opened on the top of the bending table 101 to bend the stainless steel sheet. When the bending die 203 moves downward to apply extrusion pressure to the stainless steel sheet, the first electromagnet 3 installed under the bending table 101 and the second electromagnet 301 installed inside the cross bar 202 are energized and started, and magnetic attraction is generated between the two, which applies auxiliary force to the downward pressure of the bending die 203, thereby ensuring the stability of the bending die 203 in moving downward to extrude and bend the stainless steel sheet.

[0040] After a single bending operation is completed, the bending die 203 is controlled to rise upward by the electric lifting assembly 201. Since no other structure is set above the bending die 203, the staff can adjust the position of the stainless steel sheet again and perform multiple bending operations at similar positions continuously. The stainless steel sheet that is bent to the top of the bending die 203 by the bending operation will not be blocked, and the stainless steel sheet wrapped around the outside of the bending die 203 can be moved to the right and removed after continuous bending.

[0041] The present application achieves this by installing the supporting column 2 and the electric lifting assembly 201 for controlling the lifting of the bending die head 203 on the left side, so that there is no other structure above the bending die head 203, so that the folding of the stainless steel sheet during the bending process will not be blocked, and the bending operation can be performed continuously at multiple adjacent positions, which is suitable for continuous small-size bending at the edge of the refrigerator cabinet body, which is beneficial to improving the processing convenience of the refrigerator cabinet body. At the same time, the column 2 and the electric lifting assembly 201 separately arranged on the left side make the right side of the bending die head 203 unobstructed, providing a smooth unloading position for the continuously bent stainless steel sheet. In addition, by installing the first electromagnet 3 and the second electromagnet 301, which are magnetically attracted after being energized, at the bottom of the bending table 101 and inside the cross bar 202, respectively, the force of the bending die head 203 moving down to bend the stainless steel sheet is guaranteed by magnetic attraction, thereby improving the bending effect of the device on the stainless steel sheet to a certain extent.

[0042] The bending table 101 is made of non-magnetic mold steel, and the cross bar 202 and the bending die head 203 are also made of non-magnetic mold steel. During the use of the device, the bending table 101, the cross bar 202 and the bending die head 203 are made of non-magnetic mold steel, so that the bending table 101, the cross bar 202 and the bending die head 203 do not have magnetic conductivity, and will not cause shielding or obstruction to the magnetic attraction between the first electromagnet 3 and the second electromagnet 301 after power is turned on, which is beneficial to ensure the stability of the device when bending the stainless steel sheet with the help of magnetic attraction to assist the bending die head 203.

[0043] See also Figure 5 and Figure 10 The right side cross section of the bending die 203 is set to a square structure, and the cross bar 202 is fixedly installed on the central axis of the bending die 203. During the use of the device, by setting the cross section of the bending die 203 to a square structure, the bending die 203 is used to continuously extrude and bend the stainless steel sheet. The bent end wall of the stainless steel sheet can be wrapped around the outside of the bending die 203 along the bending mark, which is conducive to continuous bending operations to the extreme degree, and then forming edge strips at the edge of the stainless steel sheet, which meets the production requirements of the refrigerator cabinet body and effectively improves the convenience of the refrigerator cabinet body processing process.

[0044] See also Figure 2The front and rear sides of the bending table 101 are rotatably mounted with symmetrical brackets 4. The top of the bracket 4 is flush with the top of the bending table 101. The hinge point of the bracket 4 and the bending table 101 is in the same horizontal plane as the top of the bending table 101. Slide grooves 401 are provided on the left and right end walls of the bracket 4. The end of the slide groove 401 close to the bending die 203 is slidably connected to a connecting rod 402. The two front and rear corresponding connecting rods 402 are hinged to each other at their ends close to each other, and the hinge point is located just below the central axis of the bending die 203. The bottom of the cross bar 202 is fixed. A pressure block 403 is fixedly installed for pressing the connecting rod 402. During the use of the device, the cross bar 202 moves up and down driven by the electric lifting component 201. When the cross bar 202 moves downward, it carries the pressure block 403 downward and acts on the connecting rod 402, so that the cross bar 202 exerts a downward pressing force on the connecting rod 402 during the downward movement, driving the side of the bracket 4 away from the connecting rod 402 to be synchronously tilted upward along with the bending of the stainless steel sheet, thereby realizing the operation of lifting the bottom tilted position of the stainless steel sheet during the bending process.

[0045] In the present application, by rotatably installing the bracket 4 on the front and rear sides of the bending table 101, and fixing the pressure block 403 on the bottom of the cross bar 202 for pressing the connecting rod 402, the bracket 4 and the stainless steel sheet can be synchronously tilted during the bending operation, so that after bending, the bracket 4 can lift and support the upward tilt of the stainless steel sheet to avoid the upward tilted part of the stainless steel sheet from falling and deforming due to excessive mass after bending, which is beneficial to ensuring the stability of the device during bending of the stainless steel sheet. At the same time, by setting the rotating hinge point of the bracket 4 to be on the same horizontal plane as the top of the bending table 101, coordinating the hinge connection between the front and rear connecting rods 402, and the sliding connection between the connecting rod 402 and the slide groove 401, the top of the bracket 4 can be fitted with the bottom of the stainless steel sheet, further ensuring the stability of the stainless steel sheet in the lifting and fitting process of the refrigerator cabinet.

[0046] See also Figure 4 The pressing block 403 is set on the left side of the bending die 203, and the pressing block 403 is located directly above the hinge point between the front and rear connecting rods 402. The bottom of the pressing block 403 is set to a right-angle structure. During the use of the device, by setting the pressing block 403 directly above the hinge point between the front and rear connecting rods 402, the pressing block 403 can accurately act on the hinge point position between the front and rear connecting rods 402 when it moves downward and presses, ensuring the stability of the downward pressing force. In the extrusion and bending process, the front and rear brackets 4 are synchronously flipped relative to each other, and the bottom of the pressing block 403 is set to a right-angle structure, so that the front and rear brackets 4 are perpendicular to each other after flipping, which is consistent with the shape formed by the bending die 203 after extrusion and bending of the stainless steel sheet.

[0047] See also Figure 4 The top of the machine 1 is supported under the bracket 4, and a limiting groove 404 is opened in the middle position of the left and right sides of the machine 1, which is located directly below the hinge point between the front and rear connecting rods 402, and the bottom angle of the limiting groove 404 is set to a right angle structure that matches the flipping trajectory of the connecting rod 402. During the use of the device, by opening the limiting groove 404 on the left and right sides of the middle position of the top of the machine 1 and setting the bottom angle of the limiting groove 404 to a right angle, the downward movement of the front and rear connecting rods 402 is restricted, thereby further ensuring the stability of the device during actual use.

[0048] See also Figure 5 The top of the roller 405 is 2 mm higher than the top of the bracket 4, which can effectively prevent the stainless steel sheet from being scratched by the friction between the roller 405 and the top of the bracket 4.

[0049] See also Figure 4 , Slide sleeves 406 are slidably installed on the left and right sides of the top of the bracket 4, and a vertically arranged limit plate 407 is fixedly installed on one side of the slide sleeve 406 near the center position of the bracket 4, and the outer surface of the limit plate 407 is set to a smooth structure, and a threaded hole is provided on the top of the slide sleeve 406 to pass through it, and a bolt 408 is connected to the threaded hole. During use of the device, by rotating the bolt 408, the tightness of the bolt 408 squeezing the top of the bracket 4 can be adjusted, and then the slide sleeve 406 can be adjusted and fixed. By sliding the slide sleeve 406 on the left and right sides of the top of the bracket 4, the positions of the left and right slide sleeves 406 and their spacing can be adjusted. The limit plates 407 on the left and right slide sleeves 406 are used to position the stainless steel sheet to be bent, which is beneficial to ensuring accurate and stable bending of the stainless steel sheet. At the same time, by setting the outer surface of the limit plate 407 to a smooth structure, it is beneficial to reduce the contact friction between the limit plate 407 and the stainless steel sheet, thereby ensuring smooth movement during bending of the stainless steel sheet.

[0050] See also Figure 5 and Figure 11 , grooves 5 are equidistantly provided from left to right at the right-angled position at the bottom of the bending die 203, and an infrared lamp 501 is fixedly installed inside the groove 5. Transparent hard resin is also encapsulated in the groove 5. During the use of the device, the infrared lamp 501 installed in the groove 5 is powered on and starts to emit a striking light beam downward. The light beam is projected onto the stainless steel sheet of the downward method to form a light marking line from left to right. This application forms a striking light marking line by projecting the light beam emitted from the groove 5 onto the stainless steel sheet of the downward method, which is helpful to assist staff in quickly correcting the bending position, thereby effectively ensuring the stability and accuracy of the stainless steel sheet bending process.

[0051] See also Figure 8 and Figure 9 An auxiliary unloading platform 6 is fixedly installed on the right end of the machine 1, and a V-shaped groove with a bottom angle of 90° is opened on the top of the auxiliary unloading platform 6. Longitudinally arranged rollers 601 are rotatably installed on the front and rear inner end walls of the V-shaped groove, and the rollers 601 are externally connected to a servo motor. A pressure sensor that is electrically connected to the control end of the electric lifting component 201 is also installed on the inner end wall of the V-shaped groove. During the use of the device, under normal circumstances, when the bent stainless steel sheet is not wrapped around the outside of the bending die 203, after the bending die 203 rises upward, the bent stainless steel sheet can be directly removed forward or backward.

[0052] When the stainless steel sheet is wrapped around the bending die 203 after being bent at multiple angles continuously, the staff moves the stainless steel sheet to the right after the bending die 203 is raised, so that the stainless steel sheet moves to the top of the auxiliary unloading platform 6. Then the staff controls the bending die 203 to descend downward through the electric lifting component 201. The stainless steel sheet moves down to the V-groove opened on the top of the auxiliary unloading platform 6 while following the descent of the bending die 203. When the pressure sensor installed in the V-groove is pressed, the signal is transmitted to the control end of the electric lifting component 201, which controls the electric lifting component. 201 stops descending, after which the servo motor is powered on and starts to drive the roller 601 to rotate, and the stainless steel sheet assisted by the sleeve on the outside of the bending die 203 moves out to the right, thereby realizing convenient unloading of the stainless steel sheet after continuous bending. The present application installs the auxiliary unloading platform 6 on the right side of the machine 1, and provides a V-shaped groove on the top of the auxiliary unloading platform 6, which cooperates with the roller 601 connected to the servo motor inside, so as to realize the auxiliary unloading of the stainless steel sheet assisted by the sleeve on the outside of the bending die 203 after continuous bending, which is conducive to ensuring the convenience of unloading the stainless steel sheet after continuous multi-angle bending during the use of the device.

[0053] The above is only the best implementation method adopted by this application in combination with current actual needs, but the scope of protection of this application is not limited to this.
