Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of rubber processing, in particular to a edge pressing device for rubber processing. Background Art
[0002] Rubber is a highly elastic polymer material. It has good elasticity at room temperature and can produce large deformation under the action of small external force. This deformation can return to its original state after the external force is removed. Rubber is divided into two types: natural rubber and synthetic rubber. Natural rubber is made by extracting Hevea brasiliensis or other plant latex, and undergoing processes such as coagulation and drying, while synthetic rubber is made by chemical methods from various monomers through polymerization reactions. Rubber is widely used in industry and life, such as manufacturing tires, hoses, tapes, cables, etc. Rubber processing is the process of making rubber into rubber products. The basic process of processing various rubber products includes basic processes such as plasticizing, mixing, calendering or pressing (i.e. extrusion), molding and vulcanization. Each process has different requirements for the product and is coordinated with several auxiliary operations, one of which involves a rubber processing edge pressing device.
[0003] However, most rubber edge pressing processes are performed by manually fixing the rubber and then pressing the edge with a lever, which is laborious and prone to defects. Insufficient pressure or ineffective fixation of the rubber can cause the rubber to deform. When faced with some special edge pressing shapes, the edge pressing operation cannot be performed accurately and quickly, which increases the difficulty of rubber edge pressing and affects the quality of rubber edge pressing.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.
[0017] Embodiment 1: Figure 1-4As shown, the utility model provides a rubber processing edge pressing device, comprising a bottom plate 1, one end of the bottom plate 1 is fixedly connected to a support frame 2, one side of the top of the bottom plate 1 is fixedly connected to two fixed blocks 3, the tops of the two fixed blocks 3 are fixedly connected to a fixing device 4, a punching device 5 is provided between the two fixed blocks 3 and the support frame 2, the punching device 5 comprises an upper pressing plate 51, one side of the bottom end of the upper pressing plate 51 is fixedly connected to an upper mold plate 52, the other side of the bottom end of the upper pressing plate 51 is fixedly connected to two sliding sleeves 53, the inner surfaces of the two sliding sleeves 53 are slidably connected to sliding rods 54, the sliding rods 5 The bottom end of the bottom plate 4 is fixedly connected to the top of the bottom plate 1, a support plate 551 is fixedly connected to the middle of the top of the bottom plate 1, and a model plate 55 is slidably connected to one end of the support plate 551 facing away from the two sliding rods 54, and a stamping module 56 is fixedly connected to one end of the model plate 55, and the second telescopic rods 552 are fixedly connected to both sides of the bottom end of the model plate 55, and the bottom ends of the two second telescopic rods 552 are fixedly connected to the top of the bottom plate 1, and four spring shafts 58 and a first telescopic rod 57 are fixedly connected to one side of the top of the bottom plate 1, and the four spring shafts 58 and the top of the first telescopic rod 57 are fixedly connected together There is a lower template 59, and a cylinder 50 is fixed on the top of the support frame 2. The output end of the cylinder 50 passes through the support frame 2 and is fixedly connected to the top of the upper pressing plate 51. When the rubber strip needs to be processed, the rubber strip is placed on the two fixed blocks 3, and then the cylinder 50 is started. The output end of the cylinder 50 applies pressure downward to the upper pressing plate 51, so that the upper pressing plate 51 moves downward through the sliding sleeves 53 and the sliding rods 54 at both ends. The upper pressing plate 51 moving downward drives the upper template 52 to be clamped on the outer surface of the stamping module 56, and the semicircular groove at one end of the upper template 52 clamps the rubber strip. Pressed tightly on the outer surface of the stamping module 56, the stamping module 56 buffers the pressure through the second telescopic rods 552 at both ends of the model plate 55, so that the model plate 55 drives the stamping module 56 to slowly descend to the top groove of the lower template 59. As the cylinder 50 continues to apply pressure, the rubber strip adheres to the outer surface of the stamping module 56 along the grooves of the upper template 52 and the lower template 59. The downward pressure applies an upward reaction force to the lower template 59 through the spring shaft 58 at the bottom and the first telescopic rod 57, forcing the rubber strip to change into a circular shape, thereby achieving the purpose of pressing the rubber edge.
[0018] The fixing device 4 includes a fixing plate 21, a sliding groove 27 is provided at the top of the fixing plate 21, a sleeve plate 23 is fixedly connected to one side of the top of the fixing plate 21, a threaded rod 24 is threadedly sleeved on the inner surface of the sleeve plate 23, a clamping plate 25 is fixedly connected to one end of the threaded rod 24, a slider 26 is slidably connected in the sliding groove 27, the bottom end of the clamping plate 25 is fixedly connected to the top of the slider 26, a clamping body 22 is fixedly connected to the other side of the top of the fixing plate 21, and one end of the threaded rod 24 is fixedly connected to the rotating rod 2 8. When the rubber strip needs to be fixed, the rubber strip is placed between the clamping plate 25 and the engaging body 22, the support frame 2 at the top of the two fixed blocks 3 is rotated, and the rotating rod 28 is rotated so that the threaded rod 24 is threadedly rotated on the inner surface of the sleeve plate 23, so that the clamping plate 25 fixed at one end of the threaded rod 24 is linearly moved along the sliding groove 27 on the outer surface of the fixed plate 21 through the slider 26 at the bottom end, and the engaging bodies 22 at both ends are fixed, thereby achieving the purpose of clamping and fixing both sides of the rubber strip.
[0019] The stamping module 56 is cylindrical, and semicircular grooves are provided at the bottom of the upper template 52 and the top of the lower template 59. The center points of the upper template 52, the stamping module 56 and the lower template 59 are on the same vertical horizontal line. The circular stamping module 56 is used to cooperate with the upper template 52 and the lower template 59 to perform stamping and curling movements. The vertically descending upper template 52 realizes one-step extrusion of the rubber with the cooperation of the lower template 59.
[0020] A slide groove is provided at one end of the model plate 55 facing the support plate 551, and circular grooves are provided on both sides of the top of the punching device 5 to cooperate with the two sliding rods 54. The slide groove facilitates the downward pressure applied by the upper template 52 to the model plate 55, so that the model plate 55 can slide up and down under the action of the sliding rod 54.
[0021] The four spring shafts 58 are distributed in a rectangular array, the lower outer surface of the upper template 52 is fitted with the upper outer surface of the lower template 59, and the bottom end of the clamping plate 25 is slidably fitted with the outer surface of the fixed plate 21. The spring shafts 58 in a rectangular array cooperate with the first telescopic rod 57 to eject under the downward pressure, and the fitted upper template 52 and lower template 59 are for better extrusion of the rubber.
[0022] Working principle: when the rubber strip needs to be processed, the rubber strip is placed on the two fixed blocks 3, and then the cylinder 50 is started. The output end of the cylinder 50 applies pressure downward to the upper pressing plate 51, so that the upper pressing plate 51 moves downward through the sliding sleeves 53 and the sliding rods 54 at both ends. The upper pressing plate 51 moving downward drives the upper template 52 to be clamped on the outer surface of the stamping module 56. The semicircular groove at one end of the upper template 52 presses the rubber strip against the outer surface of the stamping module 56. The stamping module 56 buffers the pressure through the second telescopic rods 552 at both ends of the model plate 55, so that the model plate 55 drives the stamping module 56 to slowly descend to the top groove of the lower template 59. As the cylinder 50 continues to apply pressure, the rubber strip adheres to the outer surface of the stamping module 56 along the grooves of the upper template 52 and the lower template 59. The downward pressure applies an upward reaction force to the lower template 59 through the spring shaft 58 and the first telescopic rod 57 at the bottom, forcing the rubber strip to change in a circular shape, thereby achieving the purpose of pressing the rubber edge.
[0023] When the rubber strip needs to be fixed, the rubber strip is placed between the clamping plate 25 and the engaging body 22, the support frame 2 at the top of the two fixed blocks 3 is rotated, and the rotating rod 28 is rotated so that the threaded rod 24 is threadedly rotated on the inner surface of the sleeve plate 23, so that the clamping plate 25 fixed at one end of the threaded rod 24 is moved linearly along the sliding groove 27 on the outer surface of the fixed plate 21 through the slider 26 at the bottom end, and the engaging bodies 22 at both ends are fixed, thereby achieving the purpose of clamping and fixing both sides of the rubber strip.
[0024] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
