Description

Technical Field

[0001] This utility model relates to the field of cutting device technology, and in particular to an automatic cutting device for spring strip material. Background Technology

[0002] The spring (or elastic body, Bourdon tube) is the core component of pressure measurement. When external pressure is applied to the sensor, the spring undergoes bending or expansion deformation due to the elastic properties of the material. For example, in a pressure-type temperature sensor, after the temperature-sensing material (such as gas or liquid) inside the temperature bulb expands due to heat, the pressure is transmitted to the spring through the capillary, causing it to undergo mechanical deformation. This process directly converts the pressure change into a measurable physical displacement, providing a basis for subsequent signal conversion.

[0003] Existing spring clips typically employ a cutting device to cut the entire strip into individual spring clips. The cut spring clips and waste are collected separately for convenient subsequent processing. For example, Chinese Patent Publication No. CN217476032U discloses "An Automatic Cutting Device for Small Spring Clip Strips," which includes a strip track assembly, a distance-fixed feeding assembly, a cutting assembly, and a pressing component. The strip track assembly includes a strip track and a track cover plate. The track cover plate is detachably and fixedly installed on the strip track, forming a [missing information - likely a connection or structure]. A channel for conveying material is provided, and a cutting station is provided on the channel. A fixed-distance feeding component is configured to convey the material in the channel to its flow direction at a fixed distance. The cutting component includes a stationary cutting blade and a moving cutting blade. The moving cutting blade is located below the stationary cutting blade and is connected to a cutting drive component. The stationary cutting blade is fixed at the cutting station and has a first clearance hole. A pressing component is located above the stationary cutting blade corresponding to the first clearance hole. It is configured to press the material through the first clearance hole during cutting.

[0004] In practical applications, the stamping process generates waste materials during manufacturing, including:

[0005] Improper blade clearance: If the clearance is too large, the material is easily torn, producing large burrs and debris; if the clearance is too small, the blade edge will squeeze the material, resulting in powdery debris.

[0006] Insufficient perpendicularity of the cutting edge: A tilted or bulging cutting edge can cause scraping against materials, resulting in burrs and debris.

[0007] Excessive cutting depth: The cutting edge cuts into the material too deeply, increasing the friction time with the cross-section and generating more debris;

[0008] The cutting of the springs and the mixing of waste materials can cause scratches and abrasions on the product surface, affecting the performance of the springs. When used in temperature and pressure sensors or other precision components, it can easily cause abnormal signal transmission, requiring additional manual sorting or rework, increasing time costs, and making it difficult to completely remove tiny waste materials, thus reducing the yield rate. Utility Model Content

[0009] The purpose of this utility model is to solve the shortcomings of the existing technology, such as causing scratches and abrasions on the product surface, affecting the performance of the spring sheet, easily causing abnormal signal transmission when used in precision components, difficulty in completely removing tiny wastes by manual sorting, and low yield. Therefore, an automatic cutting device for spring sheet material strip is proposed.

[0010] To achieve the above objectives, the present invention adopts the following technical solution:

[0011] Design an automatic cutting device for spring strip material, including a processing table and a material tray. A support base is fixedly installed on the processing table, and a cutting module is installed on the support base.

[0012] The cutting module is equipped with a discharge port and a waste port, and the support base is also equipped with a pressing module. A material guiding channel is provided between the pressing module and the cutting module.

[0013] The processing table is equipped with a collection box that matches the discharge port, and the collection box is equipped with a screening mechanism.

[0014] Furthermore, the cutting module includes a base plate and a punching head. The base plate has a through hole that matches the discharge port, and the punching head has a punching part that matches the through hole.

[0015] Furthermore, the base plate is connected to a mounting plate via a support tube, and a cylinder is mounted on the mounting plate. The shaft end of the cylinder passes through the mounting plate and is fixedly connected to a transmission structure, which is connected to the stamping head.

[0016] Furthermore, the screening mechanism includes a screen, a partition is fixedly installed inside the collection box, and a linear motor that is poweredly connected to the screen is installed on the collection box.

[0017] Furthermore, a pushing structure is provided on the screen, and both the pushing structure and the screen are provided with racks. Two racks are meshed with a gear, and the gear is rotatably mounted on the collection box.

[0018] Furthermore, the pushing structure includes a moving plate and a scraper. The scraper has multiple sliders integrally formed. The moving plate has multiple grooves corresponding to the sliders on the side near the scraper. A separation block is installed on the screen. The separation block and the scraper have mutually cooperating inclined surfaces.

[0019] The automatic cutting device for spring strip material proposed in this utility model has the following advantages:

[0020] In this utility model, a collection box is set on the processing table, and a screening mechanism is set in the collection box. The screening mechanism is used to screen the cut spring pieces and debris to prevent the spring pieces from mixing with waste and causing scratches and abrasions on the surface of the spring pieces.

[0021] Secondly, in this invention, the cut shrapnel and debris are screened by a screening mechanism, which is more efficient than manual sorting and collects the waste into a collection box for easy recycling. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Reference Figures 1-4 An automatic cutting device for spring strip material includes a processing table 1 and a material tray 2. A support base 3 is fixedly installed on the processing table 1, and a cutting module 4 is installed on the support base 3.

[0029] The cutting module 4 is equipped with a discharge port 5 and a waste port 6. The support base 3 is also equipped with a pressing module 7. A material guiding channel 8 is provided between the pressing module 7 and the cutting module 4.

[0030] The processing table 1 is equipped with a collection box 11 that matches the discharge port 5, and the collection box 11 is equipped with a screening mechanism 9.

[0031] In this utility model, a collection box 11 is provided on the processing table 1, and a screening mechanism 9 is provided inside the collection box 11. The screening mechanism 9 is used to screen the cut spring pieces and debris to prevent the spring pieces from mixing with waste and causing scratches or abrasions on the surface of the spring pieces.

[0032] Furthermore, in this embodiment, the cutting module 4 includes a base plate 41 and a punching head 42. The base plate 41 has a through hole that matches the discharge port 5, and the punching head 42 has a punching part that matches the through hole. The punching part of the punching head 42 punches the spring strip material to cut out suitable springs. The springs and the waste generated during cutting fall into the collection box 11 along the discharge port 5. Finally, the waste is screened by the screening mechanism 9.

[0033] Furthermore, in this embodiment, the base plate 41 is connected to the mounting plate 44 via the support tube 43. A cylinder 45 is mounted on the mounting plate 44. The shaft end of the cylinder 45 passes through the mounting plate 44 and is fixedly connected to a transmission structure 46. The transmission structure 46 is connected to the stamping head 42. The cylinder 45 drives the transmission structure 46 to move up and down, thereby driving the stamping head 42 to move up and down. Both sides of the transmission structure 46 are movably inserted into the support tube 43, serving as a guide.

[0034] It should be noted that in this embodiment, the screening mechanism 9 includes a screen 91, and a partition 92 is fixedly installed inside the collection box 11. The partition 92 separates the collection box 11 into a collection area and a waste area. A conveyor belt can be installed in the collection area to transport the spring pieces. A linear motor 93 that is poweredly connected to the screen 91 is installed on the collection box 11. The linear motor 93 drives the screen 91 to move back and forth, thereby screening out the debris and collecting it in the waste area of ​​the collection box 11.

[0035] Furthermore, in this embodiment, a pushing structure 94 is provided on the screen 91, and both the pushing structure 94 and the screen 91 are provided with racks 95. The racks 95 are slidably connected to the collection box 11, preferably located on the outer wall of the collection box 11. The collection box 11 has corresponding grooves. The racks 95 are connected to the pushing structure 94 or the screen 91 through connecting columns. The connecting columns are movably located in the grooves. A guide strip that cooperates with the racks 95 is fixedly provided on the collection box 11. The two racks 95 are meshed with a gear 96. The gear 96 is rotatably located on the collection box 11. When the screen 91 moves, under the action of the gear 96, the pushing structure 94 moves in the opposite direction to the screen 91, thereby pushing the spring into the collection area for collection.

[0036] More specifically, in this embodiment, the pushing structure 94 includes a moving plate 941 and a scraper 942. Multiple sliders are integrally formed on the scraper 942, preferably T-shaped blocks or dovetail blocks. Multiple grooves corresponding to the sliders are provided on the side of the moving plate 941 near the scraper 942. A separating block 943 is installed on the screen 91. The separating block 943 prevents some debris from being pushed by the scraper 942 to the collection area of ​​the spring sheet. The separating block 943 and the scraper 942 have mutually cooperating inclined surfaces. When the scraper 942 moves to contact the separating block 943, the two inclined surfaces contact each other, causing the scraper 942 to move along the inclined surface of the separating block 943, and the height of the scraper 942 also increases accordingly, thereby preventing the separating block 943 from obstructing the scraper 942 from pushing the spring sheet.

[0037] Working method: During operation, the stamping part of the stamping head 42 stamps the spring strip material to cut out suitable springs. The springs and the waste generated by cutting fall into the collection box 11 through the discharge port 5. The screen 91 is driven by the linear motor 93 to move back and forth, thereby removing the debris and collecting it in the waste area of ​​the collection box 11. When the screen 91 moves, the pushing structure 94 moves in the opposite direction to the screen 91 under the action of the gear 96, thereby pushing the springs into the collection area for collection.
