Description

Technical Field

[0001] This application relates to the technical field of caster seat processing equipment, and particularly to a molding machine for producing an integrated caster seat. Background Art

[0002] During the manufacturing process, the quality of the caster seat directly determines whether it can effectively transmit and disperse these forces, avoid local stress concentration, thereby extending the service life, and ensuring the stable operation of equipment, furniture, or transportation. The design of the caster seat not only needs to consider a perfect fit with the caster to ensure its stable connection, but also take into account the rationality of the overall structure to bear the huge weight and complex and changeable mechanical loads generated during the operation of the caster. A high-quality caster seat should have excellent mechanical properties, such as high strength, high toughness, good wear resistance and corrosion resistance, to cope with the challenges of various harsh environments and complex working conditions.

[0003] Traditional caster seat production mostly adopts welding and riveting methods. These methods not only have complex processes and low production efficiency; although the welding process can firmly connect different metal materials together, during the welding process, parameters such as temperature, current, and time need to be precisely controlled. Slight carelessness may lead to poor weld quality, which in turn causes uneven product strength. Welding will also generate a heat-affected zone at the joint, resulting in stress concentration, increasing the cracking risk of the product; although riveting does not involve high-temperature heating, its operation process is equally cumbersome, and there are strict requirements for the selection and installation position of the rivets. If the rivets are not selected properly or the installation position deviates during the riveting process, it will cause a decrease in the strength of the caster seat connection, affecting the stability of the overall structure; whether it is welding or riveting, it is inevitable to leave marks at the joint as the starting point of corrosion, especially in harsh environments such as humidity and salt spray, which will seriously shorten the service life of the caster seat and its connected equipment. Summary of the Invention

[0004] This device provides a molding machine for producing an integrated caster seat, and the specific implementation is as follows:

[0005] A molding machine for producing an integrated caster seat, comprising:

[0006] A plurality of die seats arranged along the transportation direction of the material plate, a die set corresponding to the die seats one by one above the material plate, and the die set is connected to the output end of the die pressing drive assembly. The die set presses against the die seat to achieve stamping and forming of the material plate;

[0007] The die sets are arranged in sequence along the conveying direction as a cutting die, a pre-punching die, a stamping die, a shaping die and a cutting die. The cutting die cuts the material plate into an integral structure composed of alternately connected caster seat bases and connecting plates. The slopes of the guide seats of the pre-punching die, the stamping die and the shaping die gradually increase, and the side plates are gradually bent and formed relative to the bottom plate by sequentially stamping on the caster seat base.

[0008] Based on the above technical solution, the caster seat is integrally formed by stamping. Through the pre-punching die, the stamping die and the shaping die, precise and gradual bending operations of the plate are realized, which not only greatly improves the batch production efficiency of the caster seat, but also significantly enhances the stability and durability of the product. During the stamping process, the pre-punching die performs preliminary positioning and punching on the caster seat base, and the stamping die gradually bends the caster seat base into the predetermined shape of the caster seat with a strong punching force, realizing uniform stress on the caster seat base, avoiding deformation or cracking caused by local stress concentration. At the same time, the efficient operation of the stamping die also ensures the continuity and stability of the production line and improves the production efficiency.

[0009] Preferably, it further includes a lower body for installing the die seat and an upper body for installing the die pressing drive assembly and the die sets. An elastic telescopic rod is provided between the lower body and the die sets.

[0010] Preferably, a conveyor belt is provided below the end of the lower body, and a hollow conduction groove communicating with the top of the conveyor belt is provided on the end die seat. A waste box for collecting the connecting plates is provided behind the end of the lower body.

[0011] Based on the above technical solution, by arranging the conveyor belt and the waste box in a staggered manner, under the action of the cutting die, the caster seat base and the connecting plate can be automatically separated and classified for conveying, further improving the automation level. By arranging the conveyor belt and the waste box in a staggered manner on the production line of the caster seat and closely combining them with the cutting die, it can ensure that after the action of the cutting die, the caster seat base and the connecting plate can be respectively conveyed to the designated positions. This layout avoids the confusion and interference between materials and provides convenience for subsequent classification processing.

[0012] Preferably, it further includes a feeder provided on the lower body, and the output end of the feeder acts on the periphery of the material plate to convey it forward.

[0013] Preferably, it further includes guide columns arranged equidistantly along the length direction of the material plate on the lower body. Grooves are provided on the inner sides of the guide columns on both sides, and the guide columns are slidably connected to both sides of the connecting plate.

[0014] Based on the above technical solution, by setting the guide columns, and the bottom of the connecting plate protrudes downward compared with the bottom of the caster seat base, and the height difference of the protrusion is the same as the height of the groove in the guide column. With the help of this height difference, the stability of the forward conveying of the material plate during the stamping process can be realized.

[0015] Preferably, the contour of the frontmost die base corresponds to the overall outer contour of the bottom plate and the side plates, and the remaining die bases have the same outer contour as the bottom plate.

[0016] Preferably, a sand channel stamping head acting on the bottom plate is provided at the center position of the bottom of the pre-punching die, and first bending guide seats acting on the side plates are provided on both sides of the bottom of the pre-punching die.

[0017] Preferably, a center stamping head acting on the bottom plate is provided at the center position of the bottom of the stamping die, and second bending guide seats acting on the side plates are provided on both sides of the bottom of the pre-punching die.

[0018] Preferably, the shaping die includes vertical bending guide seats acting on the side plates provided on both sides of the bottom.

[0019] Preferably, the cutter contour of the cutting die conforms to the arc direction of the bottom plate, and the connection between the cutter and the bottom plate and the connecting plate is vertically corresponding.

[0020] Based on the above technical solutions, the pre-punching die first acts on the side plate part of the sheet metal. Through the preset die shape and punching force, the side plate is initially turned down to a certain angle, laying a foundation for the subsequent stamping and forming. The pre-punching die also takes into account the preliminary stamping of the large sand channels on the bottom plate, preparing for the final forming of the large sand channels, reducing the resistance and deformation during the subsequent stamping process; on the basis of the pre-punching die, the stamping die further turns down the side plate a second time to ensure that the side plate reaches the final designed angle and shape. The stamping die performs the final stamping and forming of the large sand channels to make them meet the accurate dimensional and shape requirements. The stamping die also undertakes the task of stamping and forming the center hole to ensure that the center hole position of the caster seat is accurate and the size is appropriate; the shaping die finely shapes the large sand channels and small sand channels that have been initially formed on the bottom plate, eliminating the possible minor deformations or unevenness generated during the stamping process, and improving the surface quality and accuracy of the product.

[0021] In summary, the present application includes the following beneficial technical effects:

[0022] 1. The present utility model integrally forms the caster seat by stamping, and realizes the step-by-step bending operation of the sheet metal during the forming process with the aid of the pre-punching die, stamping die and shaping die, which not only ensures the batch production of the caster seat, but also improves the stability of stamping and subsequent use;

[0023] 2. The present utility model staggers the layout of the conveyor belt and the waste bin. Under the action of the cutting die, the caster seat base and the connecting plate can be automatically separated and classified for conveying, further improving the automation level;

[0024] 3. The structure of the present utility model is simple. The pre-punching die is used to initially turn down the side plate, and at the same time, it also takes into account the pre-punching of the large sand channels on the bottom plate.

The mold group 7 is sequentially arranged along the conveying direction as a cutting die 701, a pre-punching die 702, a punching die 703, a shaping die 704 and a cutting die 705. The cutting die 701 cuts the material plate 10 into an integral structure composed of alternately connected caster seat bases 12 and connecting plates 13. The guiding seat slopes of the pre-punching die 702, the punching die 703 and the shaping die 704 gradually increase, and the side plates 1202 are gradually bent and formed relative to the bottom plates 1201 by sequentially punching on the caster seat bases 12.

[0047] The contour of the frontmost die holder 8 corresponds to the overall outer contour of the bottom plate 1201 and the side plates 1202. The outer contours of the remaining die holders 8 are the same as that of the bottom plate 1201. At the center position of the bottom of the pre-punching die 702, there is a sand channel punching head 7022 acting on the bottom plate 1201.
