Description

Technical Field

[0001] The utility model belongs to the technical field of numerical control bending machines, in particular to a slide block guide device for a numerical control bending machine. Background Art

[0002] CNC bending machine is a kind of equipment that uses CNC technology to perform precise bending processing on metal sheets. It uses a computer digital control system to accurately control the bending angle, force, speed and other parameters. Compared with traditional bending machines, it has higher precision, stability and repeatability. The operator can input the corresponding parameters and instructions in the CNC system according to the processing requirements, and the machine can automatically complete the bending process. In CNC bending machines, the slider is a very important component. It is the main moving part that cooperates with the mold for bending operations. The movement of the slider is achieved through the hydraulic system or other drive devices to cooperate with the guide device. During the bending process, the slider presses up or down with the mold and works together with another mold to achieve bending and forming of the sheet.

[0003] Most of the existing slider guide devices are used for the guiding movement of a single or two sliders, and the movement direction of the slider is single. For some plates with complex bending processes, the position of the plate on the workbench needs to be continuously adjusted during the bending process so that the bending part of the plate and the mold on the slider are at the same horizontal position, and the mold installed on the slider needs to be frequently replaced to be suitable for processing different bending structures, which greatly affects the processing efficiency of the bending machine. Utility Model Content

[0004] The utility model aims to provide a slide guide device for a numerically controlled bending machine, which solves the problem of low efficiency of the existing slide guide device when processing plates with complex structures by setting a lateral adjustment component.

A plurality of guide grooves are penetrated and opened on one side of the guide plate, and connectors are slidably fitted inside the plurality of guide grooves.

[0008] The connecting piece comprises a connecting rod, and two symmetrical clamping grooves are arranged on the peripheral side of the connecting rod. The connecting rod is slidably matched with the guide groove.

[0009] The utility model is further configured such that the lateral driving component includes a servo motor fixed to the outer bottom of the support frame, the servo motor output shaft is fixedly connected to a screw, the end of the screw away from the servo motor is rotatably matched with the inner bottom of the support frame, the peripheral side of the screw is threadedly connected to a support seat, a transmission plate is fixed to the top of the support seat, and the transmission plate is fixedly connected to the guide plate by bolts.

[0010] The utility model is further configured that both ends of the connecting rod are threadedly connected to the limiting sleeves, and the ends of the two limiting sleeves away from the connecting rod are both provided with hexagonal grooves.

[0011] The utility model is further configured that a limiting groove is formed through a side surface of the support frame, and the limiting groove is slidably matched with the connecting rod.

[0012] The utility model is further configured such that the longitudinal drive assembly includes a first guide rail fixed on two opposite inner sides of the support frame, a mounting plate is slidably fitted on the two first guide rails, a hydraulic cylinder is fixed on the bottom of the mounting plate, a second guide rail is fixed on the top of the mounting plate, and a plurality of sliders are slidably fitted on the second guide rail.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Specific embodiment 1

[0032] See also Figure 1-9 The utility model is a slider guide device for a CNC bending machine, comprising a support frame 1 and a plurality of sliders 7. A longitudinal driving assembly 2 is arranged on one side of the support frame 1, and a lateral adjustment assembly 3 is arranged on the other side of the support frame 1. The lateral adjustment assembly 3 comprises a lateral driving component 4 arranged on one side of the support frame 1, and a guide component 5 is arranged on one side of the lateral driving component 4. The guide component 5 comprises two linear guide rails 501 fixedly connected to the support frame 1, and a guide plate 502 is slidably matched on the two linear guide rails 501. A plurality of guide grooves 503 are penetrated on one side of the guide plate 502, and a connecting member 6 is slidably matched inside the plurality of guide grooves 503. The connecting member 6 comprises a connecting rod 601, and two symmetrical card grooves 604 are arranged on the side surface of the connecting rod 601, and the connecting rod 601 is slidably matched with the guide groove 503.

[0033] Specifically, the lateral drive component 4 includes a servo motor 401 fixed to the outer bottom of the support frame 1, the output shaft of the servo motor 401 is fixedly connected to a screw 402, the end of the screw 402 away from the servo motor 401 is rotatably matched with the inner bottom of the support frame 1, the side surface of the screw 402 is threadedly connected to a support seat 403, the top of the support seat 403 is fixed with a transmission plate 404, and the transmission plate 404 is fixedly connected to the guide plate 502 by bolts.

[0034] Furthermore, both ends of the connecting rod 601 are threadedly connected to the limiting sleeves 602, and the ends of the two limiting sleeves 602 away from the connecting rod 601 are provided with hexagonal slots 603. One side of the plurality of sliders 7 is fixedly connected to the connecting plate 701, and one side of the connecting plate 701 is penetrated by a sliding groove 702, which is movably connected to the two slots 604.

[0035] The operation process of this embodiment is as follows: first, according to the sheet processing process, a guide plate 502 with a plurality of guide grooves 503 of a matching shape is selected for installation, and then the sliders 7 having the same number as the guide grooves 503 are installed on the longitudinal drive assembly 2. In this embodiment, two sets of symmetrical guide grooves 503 are taken as an example. After the device is installed and the sheet is ready to be bent, the servo motor 401 is started to drive the screw 402 to rotate, so that the support seat 403 moves upward or downward along the screw 402, and the support seat 403 simultaneously drives the transmission plate 403 fixedly connected thereto. 4 is moved, the transmission plate 404 drives the guide plate 502 fixedly connected thereto to move, and the guide groove 503 on the guide plate 502 drives the connecting rod 601 slidingly matched therewith to move horizontally, so that the spacing between any adjacent connecting rods 601 is changed at an equal distance, and at the same time, the connecting rod 601 drives the slider 7 to move synchronously by pushing the slide groove 702 until the slider 7 moves to the specified position, at which time the servo motor 401 stops rotating, and then drives the slider 7 to move upward through the longitudinal drive assembly 2, so that the mold installed on the slider 7 bends the specified position of the plate;

[0036] When the device processes different plates and needs to replace different guide plates 502, one end of the hexagonal wrench is inserted into the hexagonal slot 603 at one end of the limiting sleeve 602, and then the hexagonal wrench is turned to remove all the limiting sleeves 602 close to the guide plate 502 from the corresponding connecting rod 601, and then the connecting rod 601 is pushed out of the guide slot 503, and then the fixing bolts between the transmission plate 404 and the guide plate 502 are removed. After the bolts are removed, the guide plate 502 can be removed from the linear guide rail 501, and then the new guide plate 502 can be installed on the linear guide rail 501 first, and then the connecting rod 601 is inserted into the corresponding guide slot 503, and the limiting sleeve 602 is installed on the connecting rod 601 by the hexagonal wrench, and finally the transmission plate 404 and the guide plate 502 are fixedly connected by bolts;

[0037] The slide groove 702 is movably connected with the two clamping grooves 604, so that when the limit sleeve 602 is rotated by the hexagonal wrench, the connecting rod 601 will not rotate together. Figure 8 The length of the locking slot 604 is greater than the sum of the widths of the limiting sleeve 602 and the connecting plate 701 , so that the connecting rod 601 can be pushed out of the guiding slot 503 when the guiding plate 502 is disassembled. Specific embodiment 2

[0039] See also Figure 1-9On the basis of the first specific embodiment, specifically, the longitudinal drive assembly 2 includes a first guide rail 201 fixed on two opposite inner sides of the support frame 1, and a mounting plate 202 is slidably matched on the two first guide rails 201. A hydraulic cylinder 203 is fixed to the bottom of the mounting plate 202, and a second guide rail 204 is fixed to the top of the mounting plate 202. The second guide rail 204 is slidably matched with a plurality of sliders 7. A limiting groove 101 is provided through one side of the support frame 1, and the limiting groove 101 is slidably matched with the connecting rod 601.

[0040] The operation process of this embodiment is as follows: after the slider 7 moves to the specified position, the piston rod of the hydraulic cylinder 203 pushes the mounting plate 202 to move upward, and the mounting plate 202 drives the slider 7 to move upward through the first guide rail 201 fixed on the top thereof, so that the mold fixed on the slider 7 bends the plate. In the process of the slider 7 moving up and down, the connecting rod 601 slides in the slide groove 702 on one side of the connecting plate 701, so that the connecting rod 601 will not interfere with the movement of the slider 7 in the vertical direction.

[0041] The limiting groove 101 on one side of the support frame 1 not only guides the movement of the connecting rod 601, but also restricts the connecting rod 601 from moving up and down, so as to ensure that the slider 7 can achieve precise movement in the horizontal direction, and molds of different shapes can be installed on each slider 7 to avoid frequent replacement of new molds.
