Description

Technical Field

[0001] This utility model relates to the field of metal matrix composite material processing technology, and in particular to a plastic pre-compression device for metal matrix composite plates. Background Technology

[0002] In the production of metal-based composite panels, the plastic layer and the metal substrate need to be pre-pressed to achieve initial bonding, ensuring the stability of subsequent hot pressing or bonding processes. Traditional pre-pressing devices have the following drawbacks: 1. They often use manual wrenches to adjust the clamping plate spacing, resulting in uneven clamping force and easy loosening, causing the panels to shift during pre-pressing and affecting bonding accuracy; 2. The compaction mechanism is mostly driven by a single cylinder, lacking a buffer structure. Excessive instantaneous pressure can easily cause deformation of the plastic layer or damage to the metal substrate, and uneven pressure transmission can easily generate air bubbles. Utility Model Content

[0009] Preferably, the two fixing plates are arranged in a left-right mirror image, and the lower ends of the two fixing plates are fixedly connected to the upper left and upper right parts of the base plate, respectively.

[0010] Preferably, the outer surfaces of both rubber pads are bonded to the inner surfaces of the two clamping plates with strong adhesive.

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] Please see Figure 1-4 This utility model provides a technical solution: A plastic pre-compression device for metal-based composite panels includes a base plate 1, with support feet 2 fixedly connected to the four corners of the lower end of the base plate 1, mounting holes 3 opened at the upper ends of the four support feet 2, a placement platform 4 fixedly connected to the middle of the upper end of the base plate 1, and a clamping device 5 and a compaction device 6 fixedly connected to the upper end of the base plate 1.

[0020] In this embodiment, the compaction device 6 includes four base blocks 61. Each of the four base blocks 61 has an electric telescopic rod 62 fixedly connected to its upper end. Each of the four electric telescopic rods 62 has a spring 63 fitted onto its outer surface. Each of the four electric telescopic rods 62 has a top block 64 fixedly connected to its output end. Each of the four top blocks 64 has a top plate 65 fixedly connected to its upper end. A cylinder 66 is fixedly connected to the middle of the lower end of the top plate 65. A compaction plate 67 is fixedly connected to the output end of the cylinder 66. The lower ends of the four base blocks 61 are fixedly connected to the upper ends of the base plate 61. One end of each of the four springs 63 is fixedly connected to the upper ends of the four base blocks 61, and the other end is fixedly connected to the lower ends of the four top blocks 64.

[0021] The above scheme involves four base blocks 61 fixed to the base plate 1, supporting the electric telescopic rods 62. The telescopic rods 62 extend and retract, causing the top block 64 to rise and fall, thereby adjusting the height of the top plate 65. The cylinder 66 on the top plate 65 drives the compaction plate 67 to move down and compact the plate. The springs 63 connect the base blocks 61 and the top block 64 at both ends, which can buffer the pressure and avoid excessive instantaneous force. The four sets of telescopic rods and springs work together to make the top plate 65 bear force evenly and ensure that the pressure of the compaction plate 67 is transmitted evenly.

[0022] In this embodiment, the clamping device 5 includes two fixing plates 51. Each fixing plate 51 is threaded with a threaded rod 52. The inner sides of each threaded rod 52 are movably connected to a clamping plate 53 via bearings. The inner sides of each clamping plate 53 are provided with rubber pads 54. The outer sides of each threaded rod 52 are fixedly connected with circular blocks 55. The outer surfaces of each circular block 55 are fixedly connected with several rotating wheels 56. The several rotating wheels 56 are all fixedly connected with rubber rings 57. The two fixing plates 51 are arranged in a left-right mirror image, and the lower ends of the two fixing plates 51 are fixedly connected to the upper left and upper right parts of the base plate 1, respectively. The outer sides of the two rubber pads 54 are bonded to the inner sides of the two clamping plates 53 with strong adhesive. The several rotating wheels 56 are arranged in a circular array around the center of the two circular blocks 55.

[0023] With the above scheme: two fixed plates 51 are fixed to the base plate 1 in a mirror image, and the threaded rod 52 is threadedly connected to the fixed plate 51. Rotating the rotating wheel 56 with the rubber ring 57 drives the threaded rod 52 to rotate through the round block 55, so that the clamping plate 53 connected to the bearing on the inner side of the threaded rod 52 moves laterally. The rubber pad 54 on the inner side of the clamping plate 53 contacts the plate to achieve stable clamping. The rotating wheel 56 in the ring array facilitates labor-saving operation and ensures uniform clamping force.

[0024] It should be noted that this utility model is a plastic pre-compression device for metal-based composite panels. In the process of use, firstly, the metal-based composite panel is placed on the placement platform 4, ensuring that the base plate 1 is fixed firmly by the support feet 2 and the mounting holes 3. The rotating wheel 56 with rubber ring 57 in the clamping device 5 is rotated, and the threaded rod 52 is driven to rotate in the fixed plate 51 by the round block 55, so that the clamping plate 53 moves inward. The rubber pad layer 54 adheres to both sides of the panel to complete the clamping and fixing. The electric telescopic rod 62 of the compaction device 6 is started, and the top block 64 drives the top plate 65 to adjust to a suitable height. The cylinder 66 drives the compaction plate 67 to move down, and the spring 63 buffers the pressure to pre-compress the panel. After the pre-compression is completed, the cylinder 66 drives the compaction plate 67 to reset, the electric telescopic rod 62 retracts, and the rotating wheel 56 is rotated in the opposite direction to release the clamping plate 53, and the processed panel is taken out.

[0025] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
