Detailed Description
The following describes the embodiments of the present utility model further with reference to the drawings. The description of these embodiments is provided to assist understanding of the present utility model, but is not intended to limit the present utility model. In addition, the technical features of the embodiments of the present utility model described below may be combined with each other as long as they do not collide with each other.
In the prior art, a cylindrical air filter is required to be provided with its shape and structural supporting effect by the cylindrical filter support member 100 matched thereto. When assembling, it is necessary to use the cylindrical filter support member 100 as a raw material (accessory), and then to cover the cylindrical filter support member 100 with an air filter and to add end caps at the openings at both ends of the cylindrical filter support member 100 with the air filter, so as to form an air filter and use the air filter in an air purifying device.
The cylindrical filter screen supporting member 100 as a raw material (accessory) has a cylindrical shape which determines that it occupies a large space, and is disadvantageous for transportation and storage. Often damaged during shipping and storage, which affects the product quality of the final product (air filter). Cylindrical fittings do not facilitate quality inspection prior to further processing. Cylindrical parts generally take longer to inspect than planar parts. If a cylindrical fitting is purchased and reassembled into an air filter, product quality stability is not controllable because the fitting quality is not controllable. If a planar accessory (for example, the planar net-shaped filter screen supporting member 100) is purchased, the planar net-shaped filter screen supporting member 100 needs to be welded and combined before being assembled, and the welding process needs to be manually fixed and then welded, so that the labor intensity is increased and the overall production efficiency is reduced.
According to the technical scheme, the special riveting die for the filter screen supporting structure is provided, the problems that in the prior art, the production efficiency of an air filter is low, the product quality is poor, and accessories occupy the transportation storage space are solved, and the beneficial effects of improving the production efficiency and the product quality and saving the occupied space of the accessories are realized by combining the protruding part 21 of the middle edge locking die 20 with the corresponding groove 31 of the pressing die positioned below the middle edge locking die 20.
The general idea of the embodiment of the utility model for solving the technical problems is as follows:
the special riveting die for the filter screen supporting structure consists of a first die 10 positioned at the top, an intermediate edge locking die 20 positioned below the first die and a second die 30 positioned below the intermediate edge locking die 20; wherein one end of the middle locking mold 20 is provided with a protruding part 21, and the protruding part 21 is matched with a groove 31 arranged on the second pressing mold 30. When the planar filter screen support member 100 is placed between the intermediate side locking die 20 and the second die 30 and the pressing operation is started, one end of the planar filter screen support member 100 forms a groove of the pre-press bend 1, the other end of the planar filter screen support member 100 also forms a hook of the pre-press bend 2, the groove and the hook are matched, the groove and the hook form a buckling structure 110 when the planar filter screen support member 100 is curled, the planar filter screen support member 100 is curled into a cylindrical shape, and the hook and the groove are buckled together, the planar filter screen support member 100 becomes the cylindrical filter screen support member 100. The cylindrical filter screen support member 100, which contains the fastening structure 110 and is fastened together, is sent to an ultrasonic welding device for welding. At this time, the two ends of the planar filter screen supporting member 100 are not required to be gripped and fixed together by a human hand, and only the cylindrical filter screen supporting member 100 having the fastening structure 110 and fastened and combined together is required to be directly welded by the wave-welded joint.
In order to better understand the above technical solutions, the following detailed description will refer to the accompanying drawings and specific embodiments.
A special riveting die for a filter screen supporting structure is suitable for a riveting machine. As shown in fig. 1 and 2, includes a first die 10, an intermediate lockstitch die, and a second die 30; an intermediate side locking die 20 is arranged below the first die 10, and a second die 30 is arranged below the intermediate side locking die 20.
The lower part of one end of the middle edge locking mold 20 is provided with a protruding part 21, and the upper part of one end of the protruding part 21 arranged below one end of the second pressing mold 30 corresponding to the middle edge locking mold 20 is provided with a groove 31 matched with the protruding part 21.
The screen support member 100, which is typically a screen support grid sheet, places the screen support grid sheet in a position between the intermediate lock edge die 20 and the second die 30. As shown in fig. 3, the riveting machine is started, a groove is formed at one end of the filter screen supporting grid sheet between the protruding part 21 and the groove 31, a hook is formed at the other end of the filter screen supporting grid sheet far away from the protruding part 21 and the groove 31, and the groove and the hook form a buckling structure 110 shown in fig. 4 together.
As shown in fig. 4, the filter support mesh sheet forming the fastening structure 110 is curled into a cylindrical shape, and the grooves and hooks are fastened together to form a fixed cylindrical filter support mesh, and the fastening structure 110 is changed into a welded structure by an ultrasonic welding device. And (3) sleeving the air filter screen outside the welded cylindrical filter screen supporting grid, and adding cover plates at the two ends of the openings of the cylindrical filter screen supporting grid to form the air filter screen core.
In a preferred embodiment, the distance between the first die 10 and the second die is 60mm when the die as a whole is in a closed state; the length of the second die 30 is 60mm.
In order to increase the fastening degree of the fastening structure 110, the intermediate side locking mold 20 and the second press film located below the intermediate side locking mold 20 need to be further improved. As shown in fig. 2, the middle edge locking mold 20 is integrally T-shaped, and a protruding portion 21 is provided below one end of the top of the middle edge locking mold 20, and the protruding portion 21 is in a sickle shape. The second pressing mold 30 has a V-shape, preferably an asymmetric V-shape, corresponding to the groove 31 of the boss 21 to enhance the coupling force of both ends of the filter support mesh sheet. The middle portion of the middle crimping die 20 is protruded in a direction away from the top thereof to form a protrusion (corresponding to a vertical of a T-shape) which is matched with the middle recess of the second die 30.
The uniformity of the pressing force can improve the stability of the entire mold, and in order to improve the stability of the entire mold, the upper die portion (first die 10) of the mold needs to be more tightly combined with the intermediate edge locking die 20. The larger the mutual contact area of the first die 10 and the intermediate edge locking die 20 is, the more tightly the bonding between the two is, and the higher the pressing force and stability are. The bottom of the first die 10 and the top of the intermediate crimping die 20 are designed in a dome shape, which helps to increase the effective contact area of the first die 10 and the intermediate crimping die 20, thereby improving the overall stability of the die.
The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings, but the present utility model is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the utility model, and yet fall within the scope of the utility model.
