Description

Technical Field

[0001] This utility model relates to the field of garment accessory production technology, specifically a bending device for garment back button production. Background Technology

[0002] In the industrial production of garment back buttons, bending is a core process that determines product quality and production efficiency. Currently, the mainstream processing methods still rely on traditional stamping dies or manual operation. An existing patent, CN220387726U, describes a bending device comprising a support base, a moving frame, a first drive mechanism, a locking frame, a second drive mechanism, a bending frame, and a third drive mechanism. The moving frame slides along a first direction on the support base. The first drive mechanism drives the moving frame to translate. The locking frame is rotatably connected to the moving frame and has a locking port. The second drive mechanism drives the locking frame to rotate. The bending frame is rotatably connected to the locking frame and has a first bend and a second bend. The third drive mechanism drives the bending frame to rotate. In this invention, based on the locking port securing the outer arc rib, the third drive mechanism drives the bending frame to rotate relative to the locking mechanism. This allows the first and second bends to bend the protruding portions of the stirrups on the inner and outer sides of the outer arc rib, respectively. This simple and reliable method achieves convenient and efficient bending of the stirrup ends, ensuring the quality of the stirrup binding.

[0003] Regarding the aforementioned technologies, the inventors believe that the following defects exist: When using existing bending devices, due to the lack of an effective back-blowing structure, the workpiece after bending needs to be manually unloaded, and the residual material after stamping will affect the subsequent stamping of the back buckle. Therefore, we propose a bending device for garment back buckle production to solve the above-mentioned problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a bending device for garment back button production. It solves the problems of existing bending devices, which lack an effective back-blowing structure, requiring manual unloading of the bent workpiece and causing residual material residue after stamping to affect subsequent back button stamping.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a bending device for producing garment back buttons, including a support mechanism, a bracket mechanism fixedly connected to the outside of the support mechanism, and four bracket mechanisms in total, wherein every two longitudinally adjacent bracket mechanisms form a group, and the two groups of bracket mechanisms are fixedly connected to the left and right sides of the support mechanism in opposite directions.

[0006] The top of the support mechanism is fixedly connected to a top plate assembly, and a stamping push rod is installed on the bottom surface of the top plate assembly. There are two stamping push rods, which are fixedly connected in a straight array on the left and right sides of the bottom surface of the top plate assembly. The bottom surface of the stamping push rod is also fixedly connected to a bottom plate assembly and a pressure block assembly.

[0007] Preferably, a groove is provided on the top surface of the support mechanism. This groove is a forming groove, which is used to assist in bending the workpiece.

[0008] Preferably, the top surface of the support mechanism has grooves arranged in a straight line array. These grooves are assembly slots, which are semi-circular in shape and are used to place workpieces.

[0009] Preferably, a collector cylinder is fixedly connected to the top surface of the top plate assembly. The collector cylinder has an internal hollow structure, and an air supply pipe is fixedly connected to the rear side of the outer peripheral surface of the collector cylinder.

[0010] Preferably, an air supply check valve is fixedly connected to the outside of the air supply pipe, and a wind seat is fixedly connected to the side of the air supply pipe away from the manifold.

[0013] Beneficial effects

[0014] This utility model provides a bending device for garment back button production. Compared with the prior art, it has the following advantages:

[0015] This bending device for garment back button production achieves precise positioning and bending of the back button blank through the semi-circular positioning structure of the assembly groove and the preset curvature of the forming groove. This avoids curvature deviations caused by manual operation and significantly improves the consistency of the back button bending angle. The cooperation between the stamping push rod and the forming groove ensures a stable bending process and reduces wrinkles and deformation. At the same time, the pneumatic back-blowing system (compressor, air supply pipe, air seat, etc.) automatically blows off the workpiece and cleans up the slag after stamping, without manual intervention, thus avoiding defective products caused by slag residue.

[0016] This bending device for garment back button production converts mechanical motion into pneumatic power through the linkage of the guide rod assembly and piston plate when the stamping push rod is pressed down.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-6This utility model provides a technical solution: a bending device for producing garment back buttons, including a support mechanism 1, a bracket mechanism 2 fixedly connected to the outside of the support mechanism 1, and four bracket mechanisms 2 in total, wherein every two longitudinally adjacent bracket mechanisms 2 form a group, and the two groups of bracket mechanisms 2 are fixedly connected to the left and right sides of the support mechanism 1 in opposite directions.

[0026] The top of the support mechanism 2 is fixedly connected to the top plate assembly 201. The bottom surface of the top plate assembly 201 is equipped with a stamping push rod 3. There are two stamping push rods 3. The two stamping push rods 3 are fixedly connected in a straight array on the left and right sides of the bottom surface of the top plate assembly 201. The bottom surface of the stamping push rod 3 is also fixedly connected to the bottom plate assembly 301 and the pressure block assembly 3011.

[0027] Through the cooperation of support mechanism 1 and bracket mechanism 2, the four bracket mechanisms 2 are fixed in two groups to both sides of support mechanism 1, providing stable support for top plate assembly 201 and stamping push rod 3, ensuring the stability of the overall structure of the device during the stamping process, and providing a reliable mechanical foundation for back buckle bending forming.

[0028] See Figures 1-3 A groove is provided on the top surface of the support mechanism 1. The groove is a forming groove 101, which is used to assist in bending the workpiece 1012.

[0029] The forming groove 101 at the top of the support mechanism 1 has a groove structure that matches the shape of the back buckle blank. When the stamping push rod 3 drives the pressure block assembly 3011 to press down, the forming groove 101 can guide the workpiece 1012 to bend according to the preset arc, which helps to achieve precise bending and improves the consistency of the back buckle bending angle.

[0030] See Figures 5-6 The top surface of the support mechanism 1 has grooves arranged in a straight array. These grooves are assembly grooves 1011. The assembly grooves 1011 have a semi-circular structure and are used to place the workpiece 1012.

[0031] The assembly slot 1011 at the top of the support mechanism 1 is semi-circular and is used to place the workpiece 1012. The semi-circular structure can position the back buckle blank and prevent the blank from shifting during stamping. At the same time, it adapts to the arc feature at the bottom of the back buckle and ensures accurate clamping before bending.

[0032] See Figures 1-2 A collection cylinder 2011 is fixedly connected to the top surface of the top plate assembly 201. The collection cylinder 2011 has an internal hollow structure, and an air supply pipe 2012 is fixedly connected to the rear side of the outer peripheral surface of the collection cylinder 2011.

[0033] The gas flow channel is formed by connecting the top of the top plate assembly 201 with the air supply pipe 2012 through the flow collector 2011 (hollow structure), which provides an airflow carrier for subsequent backflushing and cleaning of slag. It is the core component of the pneumatic backflushing system.

[0034] See Figures 3-5 An air supply check valve 2013 is fixedly connected to the outside of the air supply pipe 2012. A wind seat 2014 is fixedly connected to the side of the air supply pipe 2012 away from the manifold 2011. The wind seat 2014 is fixedly connected to the front end of the forming groove 101 opened inside the support mechanism 1.

[0035] The air supply one-way valve 2013 on the outside of the air supply pipe 2012 can control the unidirectional flow of airflow, avoid gas backflow, ensure the stable airflow ejected from the air seat 2014, and blow the stamped workpiece 1012 out of the forming groove 101, realizing automatic unloading and cleaning of material residue.

[0036] See Figures 1-2 An air inlet pipe 2015 is fixedly connected to the top surface of the manifold 2011. The air inlet pipe 2015 is connected to the manifold 2011, and an air inlet one-way valve 2016 is fixedly connected to the outside of the air inlet pipe 2015.

[0037] By cooperating with the air inlet pipe 2015 at the top of the manifold 2011 and the air inlet check valve 2016, an external air source is allowed to supply air into the manifold 2011, providing a power source for the movement of the piston plate 3013 and the backflush airflow, ensuring a continuous air supply to the pneumatic system.

[0038] See Figures 1-4 A guide rod assembly 3012 is fixedly connected to the top surface of the base plate assembly 301. The guide rod assembly 3012 has a cylindrical structure, and a piston plate 3013 is fixedly connected to the top surface of the guide rod assembly 3012. The piston plate 3013 is slidably connected inside the collector cylinder 2011.

[0039] The guide rod assembly 3012 of the base plate assembly 301 is connected to the piston plate 3013. When the stamping push rod 3 is pressed down, the guide rod assembly 3012 drives the piston plate 3013 to slide in the collector cylinder 2011, compressing the gas in the cylinder. The compressed air is then delivered to the air seat 2014 through the air supply pipe 2012, realizing the linkage control of stamping and backflushing.

[0040] During operation, the stamping push rod 3 is activated, which drives the base plate assembly 301 and the pressure block assembly 3011 to move downward. After the pressure block assembly 3011 contacts the workpiece 1012, it continues to press down with the stamping push rod 3, pressing the workpiece 1012 into the forming groove 101. The groove contour of the forming groove 101 is consistent with the bending shape of the back buckle target, forcing the workpiece 1012 to bend along the preset arc. During this process, the support mechanism 1 resists the stamping pressure through the internal reinforcing structure to avoid deformation.

[0041] After stamping is completed, the stamping push rod 3 drives the base plate assembly 301 to reset upward. At this time, the guide rod assembly 3012 at the top of the base plate assembly 301 moves upward synchronously. The piston plate 3013 at the top of the guide rod assembly 3012 slides in the collector cylinder 2011 to compress the air in the cylinder. The collector cylinder 2011 is connected to the external air source through the air inlet pipe 2015. The air inlet check valve 2016 ensures that the gas flows into the collector cylinder 2011 in one direction. The compressed air is delivered to the air seat 2014 through the air supply pipe 2012. The air supply check valve 2013 prevents the airflow from flowing back. The air seat 2014 is located at the front end of the forming groove 101. The sprayed airflow blows the bent workpiece 1012 out of the forming groove 101 and blows away the slag generated during the stamping process to avoid residual slag affecting subsequent processing.

[0042] After the workpiece 1012 is blown down to the collection device, the operator can place a new back buckle blank in the assembly slot 1011 and repeat the above stamping and back-blowing process to achieve continuous production. The stable structure of the support mechanism 2 ensures the accuracy and reliability of the device in multiple batch stamping operations.

[0043] In summary, this device, by incorporating the pressure block assembly 3011, can perform stamping and forming operations.

[0044] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
