Description

Technical Field

[0001] This utility model relates to the field of spring production technology, and in particular to an automatic sofa spring machine for producing sofa springs. Background Technology

[0002] Sofa springs are metal components installed in the sofa frame to provide seating comfort and support. High-quality springs can extend the lifespan of the sofa and reduce the possibility of deformation and sagging.

[0003] In existing automatic sofa spring machines, the feeding mechanism uses guide rollers and pressure rollers to transport the round steel bars used for spring production. Due to prolonged contact with the raw materials, these components are prone to wear and damage. The replacement and maintenance costs of these vulnerable parts are high, and they may affect the continuity of production. To address the shortcomings of the existing technology, we propose an automatic sofa spring machine for producing sofa springs. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose an automatic sofa spring production machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An automatic sofa spring production machine includes a bottom support plate, a top support plate fixedly connected to the upper side of the bottom support plate, and a spring stamping assembly and a feeding assembly disposed between the bottom support plate and the top support plate. The feeding assembly includes an electric telescopic rod, a connecting block fixedly connected to the output end of the electric telescopic rod, an mounting ring fixedly connected to the lower side of the connecting block, and several sets of upper and lower supports laterally fixedly mounted on the mounting ring. A rotating rod is rotatably mounted on the inner side of the lower support, and an abutment seat is fixedly mounted at the bottom of the rotating rod. A telescopic cylinder is hinged between the rotating rod and the upper support. The telescopic cylinder includes a sleeve and a sliding column, the sliding column being slidably mounted on the inner side of the sleeve, an electromagnetic coil being fixedly mounted on the inner side of the sleeve, and a permanent magnet being fixedly mounted at the bottom of the sliding column.

[0007] Furthermore, a mounting side plate is fixedly installed at the bottom of the top support plate, and the electric telescopic rod is fixedly installed on the side of the mounting side plate.

[0008] Furthermore, the inner side of the abutment seat is arc-shaped and has several transverse grooves.

[0009] Furthermore, the spring stamping assembly includes an upper cylinder and a lower cylinder. The upper cylinder is fixedly installed at the bottom of the top support plate, and a stamping block is fixedly installed on the output end of the upper cylinder. A matching stamping groove is fixedly installed on the output end of the lower cylinder. An installation groove is provided on the bottom support plate, and the lower cylinder is fixedly installed at the bottom of the installation groove.

[0010] Furthermore, the stamping block is matched with the size of the matching stamping groove.

[0011] Furthermore, a sliding rod is fixedly installed on the upper side of the bottom support plate, and the sliding rod slides through the mounting ring.

[0012] Furthermore, a round steel bar is provided on the upper side of the bottom support plate, and a power switch is fixedly installed on the side wall of the bottom support plate.

[0013] Furthermore, a discharge chute is provided on the side of the matching stamping groove, and several lateral reinforcing plates are fixedly connected between the two sides of the discharge chute and the bottom support plate.

[0014] Compared with related technologies, the automatic sofa spring production machine proposed in this utility model has the following beneficial effects:

[0015] In this utility model, an automatic sofa spring production machine is described. Through a feeding assembly, the extension and retraction of a telescopic cylinder is automatically controlled by the forward and reverse energization of an inner electromagnetic coil. When the telescopic cylinder extends, it causes the contact seat to press against the outer wall of the round steel. At this time, the electric telescopic rod extends to perform material feeding. When the telescopic rod retracts, the inner electromagnetic coil of the telescopic cylinder is energized in the reverse direction to achieve retraction, causing the contact seat to rotate outward. Therefore, when the electric telescopic rod retracts, the round steel will not return in the opposite direction. Through the combined design of the above structure, intermittent cyclic material feeding is achieved. This is automated control, and the contact seat, which directly contacts the feeding components, is easy to replace. The replacement and maintenance costs of vulnerable parts are low, and maintenance is convenient, thus improving the practicality of this utility model. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Reference Figure 1-6 An automatic sofa spring production machine includes a bottom support plate 1, a top support plate 3 fixedly connected to the upper side of the bottom support plate 1, a spring stamping assembly 5 and a feeding assembly 7 disposed between the bottom support plate 1 and the top support plate 3; the feeding assembly 7 includes an electric telescopic rod 71, a connecting block 72 fixedly connected to the output end of the electric telescopic rod 71, an mounting ring 73 fixedly connected to the lower side of the connecting block 72, several sets of upper supports 75 and lower supports 76 laterally fixedly mounted on the mounting ring 73, a rotating rod 77 rotatably mounted inside the lower support 76, an abutment seat 78 fixedly mounted at the bottom of the rotating rod 77, a telescopic cylinder 79 hinged between the rotating rod 77 and the upper support 75, the telescopic cylinder 79 includes a sleeve 791 and a sliding column 793, the sliding column 793 slidably mounted inside the sleeve 791, an electromagnetic coil 792 fixedly mounted inside the sleeve 791, and a permanent magnet 794 fixedly mounted at the bottom of the sliding column 793.

[0025] In this method, the top support plate 3 is fixedly installed with the mounting side plate 6 at the bottom, and the electric telescopic rod 71 is fixedly installed with the side of the mounting side plate 6.

[0026] By setting it up in the above manner, the mounting side plate 6 provides a lateral mounting support point for the electric telescopic pole 71.

[0027] In this method, the inner side of the contact seat 78 is arc-shaped and has several transverse grooves 710.

[0028] With the above-mentioned arrangement, the inner side of the contact seat 78 is provided with several transverse grooves 710, which increases the frictional roughness of the inner side of the contact seat 78. As a result, when the contact seat 78 is pressed against the outer wall of the round steel 10, it can drive the round steel 10 to move by friction to perform material conveying.

[0029] In this configuration, a slide rod 74 is fixedly installed on the upper side of the bottom support plate 1, and the slide rod 74 slides through the mounting ring 73.

[0030] By setting the slide bar 74 in the above manner, the mounting ring 73 moves more smoothly when driven by the electric telescopic rod 71.

[0031] In this method, a round steel bar 10 is provided on the upper side of the bottom support plate 1, a power switch 2 is fixedly installed on the side wall of the bottom support plate 1, a discharge groove 8 is provided on the side of the matching stamping groove 54, and several lateral reinforcing plates 9 are fixedly connected between the two sides of the discharge groove 8 and the bottom support plate 1.

[0032] With the above configuration, the discharge groove 8 is located on the side of the spring stamping assembly 5. After the round steel 10 is stamped from the spring stamping assembly 5, it enters the discharge groove 8. The two sides of the discharge groove 8 limit the two sides of the spring sheet formed by the stamping of the round steel 10 to prevent the spring sheet from flipping.

[0033] In this method, the spring stamping assembly 5 includes an upper cylinder 51 and a lower cylinder 52. The upper cylinder 51 is fixedly installed at the bottom of the top support plate 3. A stamping block 53 is fixedly installed on the output end of the upper cylinder 51. A matching stamping groove 54 is fixedly installed on the output end of the lower cylinder 52. An installation groove 4 is provided on the bottom support plate 1. The lower cylinder 52 is fixedly installed at the bottom of the installation groove 4. The stamping block 53 and the matching stamping groove 54 are matched in size.

[0034] With the above configuration, the upper cylinder 51 and the lower cylinder 52 start synchronously. During operation, the synchronous start of the upper cylinder 51 and the lower cylinder 52 drives the stamping block 53 and the matching stamping groove 54 to move closer to each other. When the stamping block 53 and the matching stamping groove 54 are close together, the round steel 10 located in the middle is stamped to form a spring sheet.

[0035] The working principle of the automatic sofa spring production machine provided by this utility model is as follows:

[0036] In use, the round steel used for producing sofa springs is inserted into the inner side of the feeding assembly 7. The electromagnetic coil 792 inside the telescopic cylinder 79 is energized in the forward direction. The magnetic repulsion between the electromagnetic coil 792 and the permanent magnet 794 causes the telescopic cylinder 79 to extend as a whole, thereby causing the rotating rod 77 to rotate inward. This causes the contact seat 78 at the bottom of the rotating rod 77 to abut against the outer side of the round steel 10. At this time, the electric telescopic rod 71 is activated to extend, thereby feeding the round steel 10 towards the spring stamping assembly 5. After feeding is completed, the electromagnetic coil 792 inside the telescopic cylinder 79 is energized in the forward direction. When the magnetic coil 792 is energized in reverse, the magnetic attraction between the electromagnetic coil 792 and the permanent magnet 794 causes the telescopic cylinder 79 to shorten as a whole, which in turn causes the rotating rod 77 to rotate outward, so that the contact seat 78 at the bottom of the rotating rod 77 moves away from the outside of the round steel 10. At this time, the electric telescopic rod 71 retracts, waiting for the next intermittent material feeding operation. At the same time, the upper cylinder 51 and the lower cylinder 52 start synchronously, causing the stamping block 53 and the matching stamping groove 54 to move closer to each other synchronously, stamping the round steel 10 located in the middle position to form a spring sheet.

[0037] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
