Description

Technical Field

[0001] The present invention relates to the technical field of pen holder welding devices, and in particular to an automatic welding machine for a square pen holder with an edge. Background Art

[0002] A pen holder is a cylindrical stationery used to store various writing utensils. It usually has an opening and a flat bottom, and can be placed stably on the desktop. Pen holders can be made of a variety of materials, such as metal, plastic, ceramic, and wood. Similarly, the shape design can also be diversified.

[0003] The current pen holder is designed as a square or nearly square pen holder with a edging. The metal pen holder is formed by bending the metal sheet raw material and welding is performed at the joints after forming. Manual bending requires a high level of technical skills of the workers, limits the production speed, and it is difficult to ensure uniform welding quality, resulting in a high rate of product failure. Production is mostly completed by manual operation, resulting in low production efficiency, which needs to be improved. Summary of the Invention

[0004] In order to improve the problem of low production efficiency of manually produced square pen holders with wrapped edges, this technical solution provides an automatic welding machine for square pen holders with wrapped edges.

[0005] The purpose of this technical solution is achieved in this way:

[0006] An automatic welding machine for an edged square pen holder comprises a frame provided with a workbench;

[0007] A shaping module is mounted on the frame and fixed above the workbench;

[0008] A loading mechanism, which is provided on the workbench and is used to drive the workpiece to be loaded onto the shaping module;

[0009] A first punching device is mounted on the frame and is located on the side where the workpiece is fed into the shaping module, and is used to perform a first punching operation on both ends of the workpiece;

[0010] A second punching device is used to perform a second punching operation on two opposite sides of the workpiece;

[0011] A welding device, mounted on the frame, for welding the joints of the workpieces after secondary stamping;

[0012] A demoulding device is installed on the frame and is used for demoulding the workpiece after welding on the shaping module.

[0013] Through the above technical solution, when an automatic welding machine for a square pen holder with hemming is used normally, the workpiece is placed on the loading station of the workbench, and the loading mechanism drives the single workpiece to move and abut against the shaping module after loading and then return, and drives the first stamping device to stamp the workpiece so that the two opposite sides of the workpiece that are not abutting against the lower end face of the shaping die are bent upward, thereby realizing the first stamping and forming of the three side walls of the pen holder; the second stamping devices located on the opposite sides of the frame are driven to stamp the workpiece so that they are close to the workpiece so as to bend the protruding parts on both sides of the workpiece that are not abutting against the two side walls of the shaping die inward, and the second stamping surrounds the four side walls of the pen holder, and the splicing position is aligned with the welding device, and the welding device is driven to weld the splicing to ensure a firm connection to form a complete pen holder structure, and the demolding device is driven to push the pen holder out of the shaping module. Multiple devices cooperate with each other, and automated operation reduces manual intervention and improves production efficiency.

[0014] Preferably, the feeding mechanism includes a feeding assembly and a pushing assembly, the feeding assembly includes a feeding drive member and a feeding plate sliding on the workbench, and the feeding plate is provided with a material storage die seat;

[0015] The loading drive member drives the loading plate to move between a first position and a second position; when the loading plate is in the first position, the storage die seat prepares the workpiece, and when the loading plate is in the second position, the position of the storage die seat is aligned with the pusher assembly.

[0016] Through the above technical solution, the loading drive member drives the loading plate to slide, and the loading plate drives the storage die base to switch between the first position and the second position. When the storage die base is in the first position, a workpiece can be prepared in the storage die base. When it moves to the second position, it drives the workpiece position to align with the pushing assembly. The pushing assembly can push the workpiece against the shaping module, control the processing process, improve the precise positioning capability of loading, and improve the loading efficiency.

[0017] Preferably, the pushing assembly includes a pushing drive member and a pushing block sliding on the frame, and the sliding direction of the pushing block is perpendicular to the sliding direction of the loading plate;

[0018] The pusher driving member drives the pusher block to move up and down, so that the pusher block pushes the workpiece of the storage die base to lean against the shaping module.

[0019] Through the above technical solution, the pushing drive member drives the pushing block to slide upward. Based on the position of the workpiece of the storage die base, it is located between the pushing block and the shaping module, so that the workpiece is pushed against the shaping module. The abutting surface is the first side wall of the pen barrel, which limits the movement of the workpiece to facilitate the subsequent first stamping.

[0020] Preferably, the loading plate is provided with a first giveway groove, the length direction of which corresponds to the sliding direction of the loading plate, the workbench is provided with a second giveway groove, and the material storage mold base is provided with a material storage groove, one side of the first giveway groove is connected to the material storage groove, and the other side is connected to the second giveway groove, so that the pushing block can pass through the first giveway groove, the second giveway groove and the material storage groove and then lean against the shaping module.

[0021] Through the above technical solution, the width of the push block is adapted to the cross-sectional width of the giveway groove 1, the giveway groove 2 and the storage groove. The giveway groove 1 of the loading plate can always be connected to the position of the push block corresponding to the giveway groove 2 along the sliding direction. When the position of the storage groove is aligned with the push block, the push block can slide through the giveway groove 2 and the giveway groove 1 and then press the workpiece in the storage groove against the shaping module.

[0022] Preferably, the frame is provided with two first punching devices, and the two first punching devices are arranged on opposite sides of the pusher block along its sliding direction in a one-to-one correspondence;

[0023] The first stamping device includes a stamping drive member and a stamping block arranged at the driving end of the stamping drive member. The stamping block is slidingly connected relative to the push block, and the sliding direction is parallel to the sliding direction of the push block. The stamping drive member is used to drive the stamping block to move.

[0024] Through the above technical solution, the stamping drive parts on both sides respectively drive the stamping blocks at their driving ends to move synchronously in the same direction, so that the stamping blocks on both sides cooperate to slide and press the two sides of the workpiece, and the workpiece is formed into a U shape, realizing precise stamping drive.

[0025] Preferably, the spacing between the punching blocks on both sides matches the width of the shaping module.

[0026] Through the above technical solution, the gap between the two side punching blocks matches the width of the forming module, so that the punching operation of the two side punching blocks can accurately act on the workpiece to bend it upward without being hindered by the forming die base, ensuring the normal progress of the stamping operation.

[0027] Preferably, the frame is provided with two second punching devices, and the two second punching devices are located on opposite sides of the shaping module;

[0028] The second punching device includes a second punching driver and a second punching block provided at a driving end of the second punching driver. The second punching driver drives the second punching block to move. The second punching block has an abutting portion for abutting against a workpiece.

[0029] Through the above technical solution, the two stamping drive components 2 respectively drive the stamping blocks 2 at their driving ends to move synchronously in opposite directions, and the abutting part pushes the protruding part on the upper part of the workpiece to bend inward and abut against the stamping module. The stamping block 2 abuts against the side wall of the workpiece, and the bent ends of the workpiece are spliced ​​with each other to achieve precise stamping drive.

[0030] Preferably, the welding device comprises a welding drive member and a welding head provided below the welding drive member;

[0031] The welding head slides relative to the frame, and the sliding direction of the welding head is parallel to the sliding direction of the pusher block. The welding driving component is used to drive the welding head to move for welding.

[0032] Through the above technical solution, the welding drive drives the welding head to move relative to the frame, and its sliding path is consistent with the moving direction of the pusher block, that is, it approaches the forming module in a parallel direction, so that the welding head can align the joint position of the workpiece that has been stamped for the second time on the forming module to perform welding operations, thereby completing the welding.

[0033] Preferably, the demoulding device includes a demoulding module sliding on the shaping module and a demoulding driving member arranged on the frame;

[0034] The demoulding drive member drives the demoulding module to slide, and the sliding direction of the demoulding module is set along the length direction of the shaping module.

[0035] Through the above technical solution, the demoulding drive drives the demoulding module to slide back and forth along the length direction of the shaping module. The demoulding module can accurately move the workpiece after the second stamping on the shaping module, so that it can be detached from the shaping module for acquisition, thereby further improving production efficiency.

[0036] Preferably, a space is left between the frame and the workbench for the loading plate to pass through.

[0037] Through the above technical solution, the clearance space provides sliding clearance for the loading plate, thereby improving the sliding stability of the loading plate.

[0038] Compared with the existing technology, this technical solution has the following outstanding and beneficial technical effects:
