Description

Technical Field

[0001] This utility model relates to the field of molding machines, and in particular to a fully automatic molding machine unit for cable tray production. Background Technology

[0002] Cable trays are structural systems used to support, protect, and manage cables, widely used in construction, industry, power, and communications. Cable trays provide a stable support structure, preventing cables from being directly exposed or haphazardly suspended, and preventing cable displacement, sagging, or damage due to gravity, external forces, or environmental factors. Cable trays protect cables from mechanical damage, chemical corrosion, humidity, or high temperatures, extending their lifespan. A standardized cable tray system can prevent cable short circuits and open circuits, ensuring the stability of power and signal transmission and reducing the risk of accidents. Cable trays provide an orderly way to classify and organize various cables, avoiding haphazard cable laying and making maintenance and management more convenient. Using cable trays greatly simplifies the cable installation process and makes future additions or modifications to wiring easier to adjust and expand without large-scale alterations to existing facilities. Fully automatic molding machines in cable tray production are efficient and precise automated production equipment, mainly used for forming, stamping, and bending of cable tray panels. It plays a crucial role in the cable tray manufacturing process, significantly improving production efficiency, product quality, and consistency while reducing labor costs and material waste. Through automated feeding, stamping, bending, and cutting processes, it achieves integrated molding of cable tray panels, minimizing manual intervention. Compared to traditional manual or semi-automatic equipment, fully automated molding units can significantly increase production speed and meet the demands of large-volume orders.

However, when the correction mechanism is performing correction, it is inconvenient to correct sheet metal of different sizes. In view of this, a fully automatic molding machine unit for cable tray production is provided. Utility Model Content

[0004] The main purpose of this utility model is to provide a fully automatic molding machine for cable tray production, so as to solve the problem in the related technology that it is inconvenient to correct plates of different sizes when the correction mechanism is used for correction.

[0005] To achieve the above objectives, according to one aspect of this utility model, a fully automatic molding machine unit for cable tray production is provided, including a support, wherein a plurality of support plates are symmetrically fixedly installed on the middle of the upper surface of the support, a sliding groove is provided on the side wall of the support plate near the edge of the upper surface, a limit block is slidably installed in the sliding groove, a connecting block is fixedly installed on one side of the limit block, a clamping shaft is rotatably installed between the two connecting blocks, and a telescopic groove is provided on the side wall of the support plate near the lower edge. The machine also includes a positioning block, which is slidably installed in the telescopic groove, and a plurality of rotating grooves are provided on one side wall of the positioning block, in which a feeding wheel is rotatably installed.

[0011] Furthermore, a reset spring is fixedly installed on the upper surface of the sliding groove, and the other end of the reset spring is fixedly installed on the upper surface of the limit block.

[0012] Furthermore, the upper surface of the support plate is provided with a threaded hole that connects to the upper surface of the sliding groove. A clamping bolt is installed in the threaded hole, one end of which presses against the upper surface of the limit block, and a return spring is wrapped around the clamping bolt.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This fully automatic molding machine for cable tray production is equipped with a support plate. A telescopic groove is formed on the side wall of the support plate near its lower edge. A positioning block is slidably installed within the telescopic groove. Several support springs are fixedly installed on the inner side wall of the telescopic groove, with the other end of each spring fixedly installed on one side of the positioning block. One side of the positioning block has an angled section that slopes from the side wall of the support plate towards the center of the feeding chute. Several rotating grooves are formed on the side wall of the positioning block. These rotating grooves have an arc-shaped structure, and a feeding wheel is rotatably installed within each groove. One end of the feeding wheel is exposed to the outside. The angled section on one side of the positioning block facilitates the entry of the sheet metal between the two positioning blocks. The support springs push... The positioning blocks press against the sidewalls of the sheet metal to accommodate sheets of different sizes, aligning and correcting them for easy entry into the next step. This also prevents damage to the equipment from rigid collisions. The beveled angle of the positioning blocks applies pressure gradually upon contact with the sheet metal, reducing stress concentration at the connection points of the positioning blocks due to instantaneous impact. The feeding wheel contacts the sheet metal through a rotating groove, converting sliding friction into rolling friction and reducing the coefficient of friction. The arc-shaped rotating groove allows the feeding wheel to adapt to minor unevenness on the sheet metal surface, preventing localized wear caused by jamming. The symmetrically arranged positioning blocks ensure even distribution of the correction force, preventing excessive force on one side from causing deformation of the mechanism.

[0015] 2. This fully automatic molding machine for cable tray production is equipped with a sliding groove. A limit block is slidably installed in the sliding groove. A connecting block is fixedly installed on one side of the limit block. Several clamping shafts are rotatably installed between the two connecting blocks. The upper surface of the support plate has a threaded hole that connects to the sliding groove. A clamping bolt is installed in the internal thread of the thread. The clamping bolt pushes the limit block to move downward, so that the clamping shaft is brought into contact with the upper surface of the plate. By tightening the clamping bolt, the downward pressure of the clamping shaft can be precisely controlled to adapt to the correction requirements of plates of different thicknesses and avoid overload impact. The clamping shaft and the plate are clamped and corrected by rolling friction between the clamping shaft and the plate to reduce the wear of the plate. Several clamping shafts distribute the pressure to avoid excessive force at a single point, which would cause local wear. The clamping shaft presses the upper surface of the plate to prevent the plate from shifting. Attached Figure Description

[0026] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0027] This embodiment provides a fully automatic molding machine for cable tray production, including a support 1. Several support plates 11 are symmetrically fixedly installed on the middle of the upper surface of the support 1. A sliding groove 111 is opened on the side wall of the support plate 11 near the edge of the upper surface. A limit block 3 is slidably installed in the sliding groove 111. A connecting block 31 is fixedly installed on one side of the limit block 3. A clamping shaft 311 is rotatably installed between the two connecting blocks 31. A telescopic groove 112 is opened on the side wall of the support plate 11 near the lower edge. It also includes a positioning block 2. The positioning block 2 is slidably installed in the telescopic groove 112. Several rotating grooves 22 are opened on one side wall of the positioning block 2. A feeding wheel 221 is rotatably installed in the rotating groove 22. The feeding wheel 221 of the positioning block 2 presses against the side wall of the material to clamp and position the material.

[0028] like Figure 1 , Figure 2 As shown, a feeding groove 12 is provided at the center of the lower surface of the support 1. Several feeding rollers 121 are rotatably installed in the feeding groove 12. The plate moves along the feeding groove 12 by rotating the feeding rollers 121.

[0029] like Figure 2 As shown, several support springs 21 are fixedly installed on the inner side wall of the telescopic groove 112. The other end of the support spring 21 is fixedly installed on one side of the positioning block 2. The support spring 21 pushes the positioning block 2 to squeeze the side wall of the plate to adapt to plates of different sizes, so that the plate can be centered and corrected so that the plate can enter the next step, while avoiding rigid collisions that could damage the equipment.

[0030] like Figure 3 , Figure 4 As shown, a bevel is provided on one side of the positioning block 2, which is inclined from the side wall of the support plate 11 toward the middle of the feeding groove 12. The bevel on one side of the positioning block 2 facilitates the entry of the plate into the space between the two positioning blocks 2. The bevel of the positioning block 2 applies pressure gradually when it contacts the plate, reducing the stress concentration of the connection part of the positioning block 2 due to instantaneous impact.

[0031] like Figure 5 As shown, the rotating groove 22 has an arc-shaped structure. One end of the feeding wheel 221 is exposed to the outside of the rotating groove 22. The feeding wheel 221 contacts the plate through the rotating groove 22, converting sliding friction into rolling friction and reducing the coefficient of friction. The arc-shaped rotating groove 22 enables the feeding wheel 221 to adapt to the slight unevenness of the plate surface, avoiding local wear caused by jamming.

[0032] like Figure 3 As shown, the limiting block 3 is a T-shaped structure adapted to the sliding groove 111;

[0033] like Figure 3 , Figure 6 As shown, a return spring 32 is fixedly installed on the upper surface of the sliding groove 111. The other end of the return spring 32 is fixedly installed on the upper surface of the limit block 3. When the plate needs to be removed, loosen the clamping bolt 321, and the return spring 32 will reset to drive the limit block 3 to move upward so as to remove the plate.

[0034] like Figure 3 As shown, the upper surface of the support plate 11 is provided with a threaded hole that connects to the upper surface of the sliding groove 111. A clamping bolt 321 is installed in the threaded hole. One end of the clamping bolt 321 presses against the upper surface of the limiting block 3. The return spring 32 is wrapped around the clamping bolt 321. The clamping bolt 321 squeezes the limiting block 3 and pushes the limiting block 3 to move downward, so as to drive the clamping shaft 311 to fit against the upper surface of the plate. By tightening the clamping bolt 321, the downward pressure of the clamping shaft 311 can be precisely controlled to adapt to the correction requirements of plates of different thicknesses and avoid overload impact.

[0035] In practical use, the material to be fed is placed on the feeding roller 121 of the feeding trough 12. The feeding roller 121 rotates to drive the material between the two positioning blocks 2. One side of the positioning block 2 has an oblique angle that slopes from the side wall of the support plate 11 toward the middle of the feeding trough 12. The oblique angle on one side of the positioning block 2 facilitates the material to enter between the two positioning blocks 2. The oblique angle of the positioning block 2 applies pressure gradually when it contacts the material, reducing stress concentration at the connection part of the positioning block 2 due to instantaneous impact. One side of the positioning block 2 has several rotating grooves 22. The rotating grooves 22 have an arc-shaped structure. The feeding wheel 221 is rotatably installed in the rotating grooves 22. The other side of the positioning block 2 is fixedly installed with... There are several support springs 21, with the other end of each support spring 21 fixedly installed on the inner side wall of the telescopic groove 112. The support springs 21 push the positioning blocks 2 to press the side wall of the plate to adapt to plates of different sizes, so that the plates can be centered and corrected, so that the plates can enter the next step. At the same time, rigid collisions are avoided to prevent damage to the equipment. The feeding wheel 221 contacts the plate through the rotating groove 22, converting sliding friction into rolling friction and reducing the coefficient of friction. The arc-shaped rotating groove 22 allows the feeding wheel 221 to adapt to the slight unevenness of the plate surface, avoiding local wear caused by jamming. The symmetrically arranged positioning blocks 2 ensure that the correction force is evenly distributed, preventing excessive force on one side from causing deformation of the mechanism. Tighten the clamping bolt 321 in the threaded hole. The clamping bolt 321 presses against the limiting block 3 and pushes the limiting block 3 downward to drive the clamping shaft 311 to fit against the upper surface of the plate. By tightening the clamping bolt 321, the downward pressure of the clamping shaft 311 can be precisely controlled to adapt to the correction requirements of plates of different thicknesses and avoid overload impact. The clamping shaft 311 is used to clamp and correct the plate. There is rolling friction between the clamping shaft 311 and the plate to reduce the wear of the plate. Several clamping shafts 311 disperse the pressure to avoid excessive force at a single point, which would cause local wear. The clamping shaft 311 clamps the upper surface of the plate to prevent the plate from shifting.

[0036] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
