Abstract
Description
Technical Field
[0001] This utility model belongs to the field of corner code cutting technology, specifically, it relates to a processing device for window corner codes. Background Technology
[0002] Angle brackets are used for assembly during the production of aluminum alloy doors and windows. They are mainly used to connect the horizontal and vertical frames to fix the angle of the doors and windows and increase their stability. Aluminum door and window angle brackets are usually cast into a long piece during the production process, and then cut into slices according to the thickness requirements. This usually requires cutting equipment for processing.
[0003] The utility model application CN201922402973.9 (announcement number CN211332369U) discloses a corner code cutting machine for workpiece processing, belonging to the field of door and window workpiece processing device. It includes a cutter, which is mounted on the first piston rod of a first cylinder. The first cylinder is mounted on a first mounting plate, and the first mounting plate is connected to a base. A limit block is provided below the cutter to limit the vertical displacement of the cutter. The limit block is connected to a cutting fixed seat, which is connected to the base. A feeding device is provided on the other side of the base.
[0004] The spacing between the two support blocks in the above patent is not adjustable. Since the corner pieces have different lengths before cutting, if the corner piece to be cut is too long relative to the spacing between the two support blocks, instability will occur during the processing and movement of the corner piece, affecting the cutting accuracy. Utility Model Content
[0005] In view of this, the present invention provides a processing device for window corner codes, which solves the technical problem that the spacing between the support blocks is not adjustable. Since the corner codes have different lengths before cutting, if the corner code to be cut is too long relative to the spacing between the two support blocks, instability will occur during the processing and movement of the corner code, affecting the cutting accuracy.
[0006] This utility model is implemented as follows:
[0007] This utility model provides a processing device for window corner codes, which has a processing table. The front end of the processing table is the corner code cutting point. The processing table is provided with two longitudinally movable support blocks. The top wall of the support blocks is provided with an inverted triangular groove, and the groove is used to place the corner code body.
[0008] A vertically movable pressure block is provided above the support block. The bottom end of the pressure block is adapted to the groove of the support block. The support block and the pressure block together drive the corner code body to be cut to move forward.
[0009] Based on the above technical solution, the processing equipment for window corner codes of this utility model can be further improved as follows:
[0010] Furthermore, the support block is fixedly installed in the middle of the support plate, a vertical plate is fixedly installed on the support block, and a telescopic cylinder is fixedly installed on the side wall of the vertical plate. The movable end of the telescopic cylinder extends downward and its end is fixedly installed on the top wall of the pressure block.
[0011] Furthermore, longitudinally arranged racks are installed on both the left and right sides of the top wall of the processing table, and the teeth of the racks are arranged opposite each other and are meshed with a spur gear.
[0012] The spur gear on the left is rotatably connected to the left end of the front support plate, and the spur gear on the right is rotatably connected to the right end of the rear support plate.
[0013] Furthermore, the top wall of the processing table is fixed with two guide rails parallel to the rack, and two guide blocks are slidably connected to each guide rail. The bottom wall of the support plate is fixedly connected to the top wall of the two guide blocks on the same side.
[0014] Furthermore, a connecting plate is fixedly installed on the rear wall of the rear support plate, and the connecting plate is provided with a longitudinally movable push block, the bottom wall of which is slightly higher than the groove of the support block.
[0015] Furthermore, a telescopic cylinder B is fixedly installed in the transverse middle of the connecting plate. The movable end of the telescopic cylinder B extends forward and is fixedly connected to the rear wall of the push block. Rollers are fixedly installed at the four corners of the bottom wall of the connecting plate.
[0016] Compared with the prior art, the beneficial effects of the processing equipment for window corner codes provided by this utility model are:
[0017] By setting two sets of independently moving racks and spur gears, the two support blocks can be moved simultaneously, separately, closer to each other, or further away from each other by simultaneously turning on drive motor A, turning on drive motor A separately, and specifying the rotation direction of the output shaft of drive motor A, thereby adapting to various lengths of the angle to be cut.
[0018] By setting up pressure blocks that can move vertically relative to the support blocks, the distance between the pressure blocks and the corner brackets can be adjusted to achieve two modes: pressing down on the corner brackets (the support blocks and pressure blocks drive the corner brackets to move) or slightly above the corner brackets (the support blocks and pressure blocks provide guidance for the movement of the corner brackets).
[0019] The components of this processing equipment can be flexibly adjusted to facilitate moving the corner code to the processing area for cutting. Attached Figure Description

[0032] Example 1
[0033] like Figure 1-4 As shown, this utility model provides a processing device for window corner codes, which has a processing table 1. The front end of the processing table 1 is the corner code cutting point. The processing table 1 is provided with two longitudinally movable support blocks 42. The top wall of the support block 42 is provided with an inverted triangular groove, and the groove is used to place the corner code body.
[0034] A vertically movable pressure block 43 is provided above the support block 42. The bottom end of the pressure block 43 is adapted to the groove of the support block 42. The support block 42 and the pressure block 43 together drive the corner code body to be cut to move forward.
[0035] Optionally, in the above technical solution, the support block 42 is fixedly installed in the middle of the support plate 41, the support block 42 is fixedly installed with a vertical plate 44, and the side wall of the vertical plate 44 is fixedly installed with a telescopic cylinder 45. The movable end of the telescopic cylinder 45 extends downward and the end is fixedly installed on the top wall of the pressure block 43.
[0036] Optionally, in the above technical solution, both the left and right sides of the top wall of the processing table 1 are equipped with longitudinally arranged racks 51, and the teeth of the racks 51 are arranged opposite each other and are meshed with a spur gear 52.
[0037] The left spur gear 52 is rotatably connected to the left end of the front support plate 41, and the right spur gear 52 is rotatably connected to the right end of the rear support plate 41.
[0038] Furthermore, a drive motor A53 is fixedly installed on each of the support plates 41. The output axis of the drive motor A53 extends downward, passes through the support plate 41, and is connected to the spur gear 52.
[0039] Optionally, in the above technical solution, the top wall of the processing table 1 is fixed with two guide rails 46 parallel to the rack 51, and two guide blocks 47 are slidably connected on each guide rail 46. The bottom wall of the support plate 41 is fixedly connected to the top wall of the two guide blocks 47 on the same side.
[0040] Two guide rails 46 are located outside the two racks 51. A pad 2 is fixedly installed on the bottom wall of the rack 51. The rack 51 is fixedly installed on the processing table 1 through the pad 2 to raise the rack 51 and prevent the spur gear 52 from contacting the top wall of the processing table 1.
[0041] Optionally, in the above technical solution, a connecting plate 31 is fixedly installed on the rear wall of the rear support plate 41, and a longitudinally movable push block 32 is provided on the connecting plate 31. The bottom wall of the push block 32 is slightly higher than the groove of the support block 42.
[0042] Optionally, in the above technical solution, a telescopic cylinder B33 is fixedly installed in the transverse middle of the connecting plate 31. The movable end of the telescopic cylinder B33 extends forward and is fixedly connected to the rear wall of the push block 32. Rollers 34 are fixedly installed at the four corners of the bottom wall of the connecting plate 31.
[0043] The push block 32 is hollow to reduce its weight and the force on the moving end of the telescopic cylinder B33. When the moving end of the telescopic cylinder B33 is fully retracted, the push block 32 is located behind the rear pressure block 43. When the moving end of the telescopic cylinder B33 is fully extended, the push block 32 is located in front of the front pressure block 43. The purpose is to push the corner piece left on the support block 42 forward so that the corner piece left on the pressure block 43 can completely leave the rear pressure block 43 and the front pressure block 43, and thus move to the cutting point.
[0044] The telescopic cylinder 45 is a cylinder with a guide rod; the output shaft of the drive motor A53 can rotate clockwise and counterclockwise; preferably, the drive motor A53 is a geared motor.
[0045] The cylinder itself can be selected from existing equipment as needed, and the cylinder can be raised and lowered by existing control components and controllers such as solenoid valves and PLCs used to control the cylinder's raising and lowering.
[0046] During cutting, the front pressing block 43 can press the corner code tightly, and it moves upward during feeding; during cutting, the front support block 42 is located at the frontmost position.
[0047] Preferably, a rubber sheet made of rubber material is installed on the bottom wall of the pressure block 43, so that the pressure block 43 is in flexible contact with the corner code, thereby reducing the squeezing damage to the corner code to be processed.
[0048] When the corner code moves on both support blocks 42 at the same time, at least one pressure block 43 moves down to clamp the corner code.
[0049] Preferably, when the corner brackets are placed on the two support blocks 42, the corner brackets at the front of the front support block 42, the corner brackets at the rear of the rear support block 42, and the corner brackets between the two support blocks 42 have basically the same length, so as to avoid the situation where they are tilted to one side or one end is too long.
[0050] Preferably, the bottom wall of the push block 32 is slightly higher than the groove of the support block 42 by 1-3 mm, so that the push block 32 does not contact the support block 42 when it moves, but the push block 32 can still contact the rear wall of the corner bracket, thus avoiding friction caused by the contact between the push block 32 and the support block 42. Preferably, when the support block 42 provides guidance for the movement of the corner bracket, the pressure block 43 is slightly higher than the corner bracket by 1-3 mm.
[0051] The height of the upper inclined surface of the pressure block 43 in this application needs to correspond to the inclined surface of the cutting fixing seat on both sides of the cutting blade during actual processing, so that the height remains unchanged when the corner code is moved to the cutting position after being loaded.
[0052] Working principle:
[0053] In use, adjust the distance between the two support blocks 42 according to the length of the corner code to make the distance between the support blocks 42 less than the length of the corner code. At this time, the corner code can be placed on the two support blocks 42 at the same time. When the corner code is placed on the support block 42, activate the telescopic cylinder 45 to extend its movable end and drive the pressure block 43 to move down, pressing the part of the corner code located on the support block 42 onto the support block 42, so that the corner code cannot move on its own, and drive the corner code to move forward so that the cutting component cuts the corner code.
[0054] One way to move the corner code is as follows: First, both pressure blocks 43 press down on the corner code, and the two support blocks 42 move forward at the same time (the drive motor A53 needs to be started at the same time). When the corner code at the front end of the front support block 42 is cut (or the remaining corner code at the front end cannot be cut in one go), the front pressure block 43 is moved up slightly and does not contact the corner code.
[0055] At this time, the front support block 42 acts as a guide component during the forward movement of the corner code to prevent the corner code from shifting. The rear support block 42 clamps the corner code and continues to move forward, so that the corner code is cut. When the rear support block 42 moves to the position that fits the front support block 42 (the rear pressure block 43 moves up and cancels the clamping of the corner code).
[0056] At this point, the corner brackets remaining on the two support blocks 42 cannot move further. Then, the telescopic cylinder B33 is activated to drive the push block 32 forward along the support block 42, pushing the remaining corner brackets forward so that the corner brackets are completely cut off.
[0057] The adjustment method of the support block 42 is as follows: the front drive motor A53 is started, causing its conveying shaft to drive the spur gear 52 to rotate clockwise or counterclockwise. With the left rack 51 fixed, the spur gear 52 moves forward or backward while rotating by meshing with the rack 51, thereby driving the front drive motor A53 and the support plate 41, etc., to move in the same direction under the guidance of the guide rail 46.
[0058] When the rear drive motor A53 is started, its conveyor shaft drives the spur gear 52 to rotate clockwise or counterclockwise. With the right rack 51 fixed, the spur gear 52 moves forward or backward while rotating by meshing with the rack 51, thereby driving the rear drive motor A53 and support plate 41, etc., to move in the same direction under the guidance of the guide rail 46.
[0059] Adjust the longitudinal position of the support blocks 42 respectively to change the distance between the two support blocks 42. As needed, both support blocks 42 can be adjusted, or only one support block 42 can be adjusted.
[0060] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
